Face masks have been linked to dry eye complaints in recent studies. <strong>Purpose:</strong> To evaluate the changes in tear-film status and Ocular Surface Disease Index (OSDI) score following prolonged use of face mask. <strong>Design:</strong> Cross-sectional study. <strong>Method:</strong> Patients between 18 to 70 years using masks regularly for at least 2 hours/day for at least 5 days/week from different eye-care centres in Dhaka were included. All subjects were divided into 4 groups. Mask use lasted approximately 2 hours/day in Group 1, 4 hours/day in Group 2, 6 hours/day in Group 3 and 8 hours or more/day in Group 4. Evaluation of symptoms, tear- film stability and tear volume was done by Ocular Surface Disease Index (OSDI) scores, Tear-film Break-Up Time (TBUT) and Schirmer-1 test. Average of right & left eye’s Tear-film Break Up time (TBUT) and Schirmer-1 value were noted. <strong>Results:</strong> Total 100 patients were enrolled (n = 100). The TBUT (p < 0.001) and Schirmer-1 measurement (p = 0.01) were significantly lesser and Ocular Surface Disease Index (OSDI) score were significantly higher in patients using face-masks for longer time (p < 0.001). <strong>Conclusion:</strong> Patients who wore masks for prolonged time had tear film instability, reduced tear volume and higher Ocular Surface Disease Index (OSDI) score.展开更多

OBJECTIVE: To investigate the possible risk factor of cerebral infarction plus peripheral arterial disease (PAD), compare metabolic characteristics of patients who having CI plus PAD or only having CI, and understand the significance of ABI on screening and diagnosing CI plus PAD of lower limb. DESIGN: Contrast observation based on CI patients. SETTING: Department of Neurology, Nanxishan Hospital of Guangxi Zhuang Autonomous Region. PARTICIPANTS: A total of 124 CI patients were selected from Department of Neurology, Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2005 to April 2006, including 72 males and 52 females aged from 45 to 88 years. All patients met the diagnostic criteria of cerebrovascular disease established by National Academic Conference of Cerebrovascular Diseases in 1995 and determined as cerebral infarction with MRI or CT examination. All patients provided informed consent. There were 46 cases (37.2%) with CI plus PAD and 78 cases (62.8%) only with CI. METHODS: Blood pressure of bilateral ankles and upper extremities was measured at plain clinostatism with DINAMAP blood pressure monitor (GE Company). The ratio between average systolic pressure of lateral ankle and average systolic pressure of both upper extremities was regarded as ABI. The normal ABI was equal to or more than 0.9. If ABI < 0.9 occurred at one side, patients were diagnosed as PAD. On the second morning after hospitalization, blood was collected to measure fasting blood glucose (FBG), 2-hour postprandial blood glucose (PBG2h), glycosylated hemoglobin (HbA1c), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Among them, blood glucose, lipid and other biochemical markers were measured with enzyme chemistry assay and HbA1c was measured with HbA1c meter based on high liquid phase. Measurement data and enumeration data were compared with t test and Chi-square test, and multiple factors were dealt with Logistic regression analysis and multivariate linear regression analysis. MAIN OUTCOME MEASURES: Results of correlation between ABI and metabolic markers with multivariate linear regression analysis; risk factors of CI plus PAD with Logistic regression analysis; comparisons of metabolic markers between PAD and non-PAD patients. RESULTS: All 124 patients with acute CI were involved in the final analysis. ① Comparisons of metabolic markers: Levels of serum LDL-C and uric acid (UA) were higher of PAD patients than those of non-PAD patients (t =2.051 9, 3.339 1, P < 0.05); however, there were no significant differences among other metabolic markers (P > 0.05). ② Results of multivariate linear regression analysis: PBG2h, LDL-C and UA were obvious correlation with ABI of posterior tibial artery of lower limb and dorsal pedis artery (partial regression coefficient = -0.231 to -1.010, P < 0.05). ③ Risk factors of CI plus PAD with Logistic regression analysis: Age, smoking history, sum of CI focus (≥3) and LDL-C were independent risk factor of CI plus PAD (OR =1.524-5.422, P < 0.05-0.01). CONCLUSION: ① Levels of serum LDL-C and UA of patients with CI plus PAD are high. ② ABI of lower limbs is correlation with PBG2h, LDL-C and UA. In addition, measuring ABI is beneficial for early diagnosing PAD of lower limbs of patients who have poorly controlled blood glucose, abnormal lipid and poor renal function. ③ Age, LDL-C and sum of CI focus (≥3) are independent risk factors of CI plus PAD. It is of significance for screening non-PAD patients to evaluate risk degrees and prognosis and select therapeutic methods based on ABI measurement.展开更多

Disease conditions rose with the advancing growth stage, which grew more quickly during the early stage of anthesis, flower withering period and early si- lique mature period. Yield less rate increased with the increasing stem disease rate and disease index. Yield loss rate( Y1 ) had extremely significant correlation with stem disease rate(X1 )and disease index(X2 ), and the related models were Y1 = 0. 544 330 2X1 -2. 316 1 (n = 14, r --0. 986 0 * * )and YI = 0. 673 408 X2 - 1. 016 4 ( n = 14 ,r = 0.977 2 ~ * ), respectively. Disease control indexes for one time control against S. sclerotlorum in mechanical direct seeding fields were stem disease rate as 11.8% and disease index as 7.6, respectively. The control indexes for twice control against the disease were stem disease rate as 16.8% and disease index as 11.7. This paper provided a new scientific basis for preventing S. sclerotiorum in mechanical direct seeding fields.展开更多

METHODS: We reviewed and analyzed the responses of 334 patients to a specifically designed questionnairebased on the short inflammatory bowel disease questionnaire (SIBDQ) and the German pain questionnaire. Pain intensity, HRQOL, Crohn’s disease activity index (CDAI) and colitis activity index (CAI) were correlated and verified on a visual analog scale (VAS). RESULTS: 87.9% of patients reported pain. Females and males reported comparable pain intensities and HRQOL. Surgery reduced pain in both genders (P = 0.023), whereas HRQOL only improved in females. Interestingly, patients on analgesics reported more pain (P = 0.003) and lower HRQOL (P = 0.039) than patients not on analgesics. A significant correlation was found in UC patients between pain intensity and HRQOL (P = 0.023) and CAI (P = 0.027), and in CD patients between HRQOL and CDAI (P = 0.0001), but not between pain intensity and CDAI (P = 0.35). No correlation was found between patients with low CDAI scores and pain intensity. CONCLUSION: Most IBD patients suffer from pain and have decreased HRQOL. Our study reinforces the need for effective individualized pain therapy in IBD patients.展开更多

Its morbidity and mortality have remained high owing to complications of extensive skin involvement as well as its conventional steroid therapy. We reviewed the medical literature and found indicators of an autoimmune etiology for its pathogenesis triggering genetically predisposed patients. Objective: to evaluate, prospectively, the role of Rituximab (R) therapy in its persistent, severe and extensive form. Patients and methods: A total of 12 patients, with disease duration of 6 ± 1 months, were treated with yearly R infusions (1 g followed by 1 g 2 weeks later). Results: Significant clinical improvement was achieved as documented by decrease in total score of Bullous Pemphigoid Disease Area Index from 60 ± 3 to 6 ± 2 that persisted for 26 ± 11 months of follow up. Moreover, IBP autoantibodies (anti-BP 180 and anti-320 IgG) levels fell from to 91 ± 3 and 81 ± 2 to 8 ± 2 and 9 ± 2, respectively. Conclusions: R is a safe and effective treatment for severe IBP and such response further confirms its autoimmune pathogenesis.展开更多

The reiults showed that the disease index and diseased plant rate of eggplant verticillium wilt were the lowest in the plots with substrate treatment and root-irrigation treatnent. The control effects in the plots with substrate treatment were higher than those in the plots with only root irrigation treatment. Moreover, higher concentration of microbial fertilizer resulted in better control effect and higher yield. Thus, the microbial fertilizer had a broad application prospect.展开更多

The included patients received 1 capsule thrice a day of placebo or curcumin(150 mg) for 8 wk. Patients were evaluated clinically and endoscopically at 0,4 and 8 wk. The primary outcome was clinical remission at 8 wk and secondary outcomes were clinical response, mucosal healing and treatment failure at 8 wk. The primary analysis was intention to treat worst case scenario(ITT-WCS).RESULTS Of 300 patients with UC, 62 patients(curcumin: 29, placebo: 33) fulfilled the inclusion criteria and were randomized at baseline. Of these, 21 patients did not complete the trial, 41 patients(curcumin: 16, placebo: 25) finally completed 8 wk. There was no significant difference in rates of clinical remission(31.3% vs 27.3%, P = 0.75), clinical response(20.7% vs 36.4%, P = 0.18), mucosal healing(34.5% vs 30.3%, P = 0.72), and treatment failure(25% vs 18.5%, P = 0.59) between curcumin and placebo at 8 wk.CONCLUSION Low dose oral curcumin at a dose of 450 mg/d was ineffective in inducing remission in mild to moderate cases of UC.展开更多
文摘AIM:To assess the reliability of web-based version of ocular surface disease index in Chinese(C-OSDI)on clinically diagnosed dry eye disease(DE)patients.METHODS:A total of 254 Chinese participants(51%male,129/254;mean age:27.90±9.06 y)with DED completed paper-and web-based versions of C-OSDI questionnaires in a randomized crossover design.Ophthalmology examination and DED diagnosis were performed prior to the participants being invited to join the study.Participants were randomly designated to either group A(paper-based first and webbased second)or group B(web-based first and paper-based second).Final data analysis included participants that had successfully completed both versions of the C-OSDI.Demographic characteristics,test-retest reliability,and agreement of individual items,subscales,and total score were evaluated with intraclass correlation coefficients(ICC),Spearman rank correlation,Wilcoxon test and Rasch analysis.RESULTS:Reliability indexes were adequate,Pearson correlation was greater than 0.8 and ICCs range was 0.827 to 0.982;total C-OSDI score was not statistically different between the two versions.The values of mean-squares fit statistics were very low compared to 1,indicating that the responses to the items by the model had a high degree of predictability.While comparing the favorability 72%(182/254)of the participants preferred web-based assessment.CONCLUSION:Web-based C-OSDI is reliable in assessing DED and correlation with the paper-based version is significant in all subscales and overall total score.Webbased C-OSDI can be administered to assess individuals with DED as participants predominantly favored online assessment.
文摘<strong>Background:</strong> Dry eye is characterized by tear film instability, decreased tear volume and a high Ocular Surface Disease Index (OSDI) score. Face masks have been linked to dry eye complaints in recent studies. <strong>Purpose:</strong> To evaluate the changes in tear-film status and Ocular Surface Disease Index (OSDI) score following prolonged use of face mask. <strong>Design:</strong> Cross-sectional study. <strong>Method:</strong> Patients between 18 to 70 years using masks regularly for at least 2 hours/day for at least 5 days/week from different eye-care centres in Dhaka were included. All subjects were divided into 4 groups. Mask use lasted approximately 2 hours/day in Group 1, 4 hours/day in Group 2, 6 hours/day in Group 3 and 8 hours or more/day in Group 4. Evaluation of symptoms, tear- film stability and tear volume was done by Ocular Surface Disease Index (OSDI) scores, Tear-film Break-Up Time (TBUT) and Schirmer-1 test. Average of right & left eye’s Tear-film Break Up time (TBUT) and Schirmer-1 value were noted. <strong>Results:</strong> Total 100 patients were enrolled (n = 100). The TBUT (p < 0.001) and Schirmer-1 measurement (p = 0.01) were significantly lesser and Ocular Surface Disease Index (OSDI) score were significantly higher in patients using face-masks for longer time (p < 0.001). <strong>Conclusion:</strong> Patients who wore masks for prolonged time had tear film instability, reduced tear volume and higher Ocular Surface Disease Index (OSDI) score.
文摘BACKGROUND The pediatric Crohn’s disease activity index(PCDAI)is used as a standard tool to assess disease activity in clinical trials for pediatric Crohn’s disease.AIM To examine which items on the PCDAI drive assessment of disease activity,and how subgroups of subjective and objective items reflect change in disease state over time.METHODS Selective raw data from three prospectively collected datasets were combined,including 703 children with full PCDAI data at baseline,at 3-mo(Q1,n=670),and 1-year(Q4,n=474).Change in individual PCDAI scores from baseline to Q1 and to Q4 were examined using the non-weighted PCDAI.RESULTS Abdominal pain,well-being,weight,and stooling had the highest change scores over time.Objective indicators including albumin,abdominal exam,and height velocity followed.Change scores for well-being and abdominal exam did not explain significant variance at Q1 but were significant predictors at Q4(P<0.001 and P<0.05).Subjective and objective subgroups of items predicted less variance(18%and 22%)on total PCDAI scores at Q1 and Q4 compared to the full PCDAI,or a composite scale(both 32%)containing significant predictors.CONCLUSION Although subjective items on the PCDAI change the most over time,the full PCDAI or a smaller composite of items including a combination of subjective and objective components classifies disease activity better than a subgroup of either subjective or objective items alone.Reliance on subjective or objective items as stand-alone proxies for disease activity measurement could result in misclassification of disease state.

文摘We aimed to develop a disease risk comorbidity index(DRCI)based on disease risk index(DRI)and Hematopoietic Cell Transplantation-Specific Comorbidity Index(HCT-CI)in patients receiving haploidentical hematopoietic stem cell transplantation(haplo-HSCT).We identified the prognostic factors of disease-free survival(DFS)in a training subset(n=593),then assigned a weighted score using these factors to the remaining patients(validation subset;n=296).The multivariable model identified two independent predictors of DFS:DRI and HCT-CI before transplantation.In this scoring system,we assigned a weighted score of 2 to very high-risk DRI,and assigned a weighted score of 1 to high-risk DRI and intermediate-and high-risk HCT-CI(i.e.,haplo-DRCI).In the validation cohort,the three-year DFS rate was 65.2%(95%confidence interval(CI),58.2%–72.2%),55.8%(95%CI,44.9%–66.7%),and 32.0%(95%CI,5.8%–58.2%)for the low-,intermediate-,and high-risk group,respectively(P=0.005).Haplo-DRCI can also predict DFS in disease-specific subgroups,particularly in acute leukemia patients.Increasing score was also significantly predictive of increased relapse,increased non-relapse mortality(NRM),decreased DFS,and decreased overall survival(OS)in an independent historical cohort(n=526).These data confirmed that haplo-DRCI could effectively risk stratify haplo-HSCT recipients and provide a tool to better predict who will best benefit from haplo-HSCT.
文摘BACKGROUND: Ankle brachial index (ABI) is widely involved in researches and clinical application of peripheral vascular injury of patients with diabetes mellitus (DM); however, the application in cerebral infarction (CI) is rare. OBJECTIVE: To investigate the possible risk factor of cerebral infarction plus peripheral arterial disease (PAD), compare metabolic characteristics of patients who having CI plus PAD or only having CI, and understand the significance of ABI on screening and diagnosing CI plus PAD of lower limb. DESIGN: Contrast observation based on CI patients. SETTING: Department of Neurology, Nanxishan Hospital of Guangxi Zhuang Autonomous Region. PARTICIPANTS: A total of 124 CI patients were selected from Department of Neurology, Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2005 to April 2006, including 72 males and 52 females aged from 45 to 88 years. All patients met the diagnostic criteria of cerebrovascular disease established by National Academic Conference of Cerebrovascular Diseases in 1995 and determined as cerebral infarction with MRI or CT examination. All patients provided informed consent. There were 46 cases (37.2%) with CI plus PAD and 78 cases (62.8%) only with CI. METHODS: Blood pressure of bilateral ankles and upper extremities was measured at plain clinostatism with DINAMAP blood pressure monitor (GE Company). The ratio between average systolic pressure of lateral ankle and average systolic pressure of both upper extremities was regarded as ABI. The normal ABI was equal to or more than 0.9. If ABI < 0.9 occurred at one side, patients were diagnosed as PAD. On the second morning after hospitalization, blood was collected to measure fasting blood glucose (FBG), 2-hour postprandial blood glucose (PBG2h), glycosylated hemoglobin (HbA1c), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Among them, blood glucose, lipid and other biochemical markers were measured with enzyme chemistry assay and HbA1c was measured with HbA1c meter based on high liquid phase. Measurement data and enumeration data were compared with t test and Chi-square test, and multiple factors were dealt with Logistic regression analysis and multivariate linear regression analysis. MAIN OUTCOME MEASURES: Results of correlation between ABI and metabolic markers with multivariate linear regression analysis; risk factors of CI plus PAD with Logistic regression analysis; comparisons of metabolic markers between PAD and non-PAD patients. RESULTS: All 124 patients with acute CI were involved in the final analysis. ① Comparisons of metabolic markers: Levels of serum LDL-C and uric acid (UA) were higher of PAD patients than those of non-PAD patients (t =2.051 9, 3.339 1, P < 0.05); however, there were no significant differences among other metabolic markers (P > 0.05). ② Results of multivariate linear regression analysis: PBG2h, LDL-C and UA were obvious correlation with ABI of posterior tibial artery of lower limb and dorsal pedis artery (partial regression coefficient = -0.231 to -1.010, P < 0.05). ③ Risk factors of CI plus PAD with Logistic regression analysis: Age, smoking history, sum of CI focus (≥3) and LDL-C were independent risk factor of CI plus PAD (OR =1.524-5.422, P < 0.05-0.01). CONCLUSION: ① Levels of serum LDL-C and UA of patients with CI plus PAD are high. ② ABI of lower limbs is correlation with PBG2h, LDL-C and UA. In addition, measuring ABI is beneficial for early diagnosing PAD of lower limbs of patients who have poorly controlled blood glucose, abnormal lipid and poor renal function. ③ Age, LDL-C and sum of CI focus (≥3) are independent risk factors of CI plus PAD. It is of significance for screening non-PAD patients to evaluate risk degrees and prognosis and select therapeutic methods based on ABI measurement.

文摘Real-time monitoring and investigation in fields showed that the disease starting period of Sclerotinia sclerotiorum in mechanical direct seeding fields was earlier. Disease conditions rose with the advancing growth stage, which grew more quickly during the early stage of anthesis, flower withering period and early si- lique mature period. Yield less rate increased with the increasing stem disease rate and disease index. Yield loss rate( Y1 ) had extremely significant correlation with stem disease rate(X1 )and disease index(X2 ), and the related models were Y1 = 0. 544 330 2X1 -2. 316 1 (n = 14, r --0. 986 0 * * )and YI = 0. 673 408 X2 - 1. 016 4 ( n = 14 ,r = 0.977 2 ~ * ), respectively. Disease control indexes for one time control against S. sclerotlorum in mechanical direct seeding fields were stem disease rate as 11.8% and disease index as 7.6, respectively. The control indexes for twice control against the disease were stem disease rate as 16.8% and disease index as 11.7. This paper provided a new scientific basis for preventing S. sclerotiorum in mechanical direct seeding fields.
文摘AIM: To evaluate intensity, localization and cofactors of pain in Crohn’s disease and ulcerative colitis patients in connection with health-related quality of life (HRQOL) and disease activity. METHODS: We reviewed and analyzed the responses of 334 patients to a specifically designed questionnairebased on the short inflammatory bowel disease questionnaire (SIBDQ) and the German pain questionnaire. Pain intensity, HRQOL, Crohn’s disease activity index (CDAI) and colitis activity index (CAI) were correlated and verified on a visual analog scale (VAS). RESULTS: 87.9% of patients reported pain. Females and males reported comparable pain intensities and HRQOL. Surgery reduced pain in both genders (P = 0.023), whereas HRQOL only improved in females. Interestingly, patients on analgesics reported more pain (P = 0.003) and lower HRQOL (P = 0.039) than patients not on analgesics. A significant correlation was found in UC patients between pain intensity and HRQOL (P = 0.023) and CAI (P = 0.027), and in CD patients between HRQOL and CDAI (P = 0.0001), but not between pain intensity and CDAI (P = 0.35). No correlation was found between patients with low CDAI scores and pain intensity. CONCLUSION: Most IBD patients suffer from pain and have decreased HRQOL. Our study reinforces the need for effective individualized pain therapy in IBD patients.

文摘Objective:The ulcerative colitis endoscopic index of severity(UCEIS)and the Mayo endoscopic score(MES)are developed as objective methods of evaluating endoscopic severity in patients with ulcerative colitis(UC).The aim of this study is to investigate the diagnostic accuracy of the UCEIS and MES in predicting the patient's response to mesalazine.Methods:Consecutive patients with UC who had undergone colonoscopy within 1 month before starting mesalazine between October 2011 and July 2016 were retrospectively collected at the Department of Gastroenterology,Sir Run Run Shaw Hospital,Zhejiang University School of Medicine.The median follow-up was 81 months,and all the data were analyzed in January 2021.The primary outcome was the need for step-up treatment,which included the use of corticosteroids,immunomodulatory,or surgery during admission and follow-up.Data were analyzed using the c2 or Fisher exact test,Spearman test,t-test,and ManneWhitney U test.Results:Totally,65 patients were enrolled,of whom 12(18.5%)needed step-up treatment due to nonresponse to mesalazine.The UCEIS score,MES,and the ulcerative colitis disease activity index(UCDAI)score were significantly higher in patients who had nonresponse to mesalazine(UCEIS score:6.92±0.69 vs.4.45±1.17,p<0.001;MES:2.67±0.49 vs.2.15±0.69,p=0.024;UCDAI score:9.33±1.87 vs.6.70±2.38,p=0.002).In the multivariate analysis,the UCEIS score(OR=25.65,95%CI:3.048 e45.985,p=0.003),UCDAI score(OR=1.605,95%CI:1.144e2.254,p=0.006),and C-reactive protein level(OR=1.056,95%CI:1.006e1.108,p=0.026)were independent risk factors of nonresponse.The area under the ROC curve of UCEIS was 0.95,with a sensitivity of 100%and specificity of 84.6%,a cut-off value of 6,which outperformed the MES with an area under the ROC curve of 0.70.When the UCEIS score≥6,60%of patients eventually needed step-up treatment.Conclusions:The UCEIS is a useful instrument for predicting the therapeutic effect in patients with UC treated with mesalazine.The high probability of mesalazine treatment failure and benefits of other therapies should be discussed in patients with baseline UCEIS score≥6.
文摘Capsule endoscopy(CE)is a recently developed diagnostic method for diseases of the small bowel that is non-invasive,safe,and highly tolerable.Its role in patients with inflammatory bowel disease has been widely validated in suspected and established Crohn’s disease(CD)due to its ability to assess superficial lesions not detected by cross-sectional imaging and proximal lesions of the small bowel not evaluable by ileocolonoscopy.Because CE is a highly sensitive but less specific technique,differential diagnoses that can simulate CD must be considered,and its interpretation should be supported by other clinical and laboratory indicators.The use of validated scoring systems to characterize and estimate lesion severity(Lewis score,Capsule Endoscopy Crohn’s Disease Activity Index),as well as the standardization of the language used to define the lesions(Delphi Consensus),have reduced the interobserver variability in CE reading observed in clinical practice,allowing for the optimization of diagnoses and clinical management strategies.The appearance of the panenteric CE,the incorporation of artificial intelligence,magnetically-guided capsules,and tissue biopsies are elements that contribute to CE being a promising,unique diagnostic tool in digestive tract diseases.

文摘AIM:To explore the relationship between ocular and systemic conditions and the impact of ocular complications on the quality of life(QOL)in patients after allogeneic hematopoietic stem cell transplantation(ALLO-HSCT).METHODS:Forty-four patients with severe hematopoietic disease were enrolled after ALLO-HSCT at our center from July 2018 to October 2020.They completed two questionnaires:the Ocular Surface Disease Index(OSDI)and the quality-of-life scale for Chinese patients with visual impairment(SQOL-DV1).Ocular conditions and systemic conditions were also assessed.RESULTS:Eye damage was correlated with total bilirubin(P=0.005),and gamma-glutamyl transferase(GGT)(P=0.021).There was no significant correlation between the overall QOL score and OSDI(P=0.8226)or SQOLDV1(P=0.9526)scores.The OSDI and the overall QOL score were not correlated with ocular conditions,including best-corrected visual acuity(BCVA),intraocular pressure,Schirmer tear test II,sodium fluorescein staining,tear film breakup time,and tear meniscus height.SQOLDV1 was correlated with BCVA(P=0.0007),sodium fluorescein staining(P=0.007),and tear film breakup time(P=0.0146).CONCLUSION:In some patients,early ocular symptoms are not evident after ALLO-HSCT,while ocular surface complications can be observed after a comprehensive ophthalmological examination.Especially for those with elevated total bilirubin or GGT,regular ophthalmic follow-up visits are essential to diagnose and treat ocular graft versus host disease(o GVHD),especially for patients with elevated total bilirubin or GGT.
文摘[Objectives]The paper was to investigate the effects of different application rates of pesticides and fertilizers on wheat stripe rust and wheat yield.[Methods]Two-factor split block design was adopted.[Results]Different application rates of pesticides and chemical fertilizers would affect the incidence of wheat stripe rust,and further affect the yield of wheat.Triadimefon had no significant effect on wheat yield,and potassium sulfate compound fertilizer had significant effect on wheat yield,while their interaction had no significant effect on wheat yield.There were significant differences in wheat yield among the 15 treatment combinations,which may be due to the fact that the application rate of potassium sulfate compound fertilizer had extremely significant effect on wheat yield.[Conclusions]Under the wheat/green manure/maize zonal rotation system in Bijie,the sowing width of wheat is guaranteed to be 0.5 m under the 1.65 m zonal cropping system,and the sowing rate of wheat is arranged according to the basic seedling of 1.2 million plants/hm^(2).In the early stage of wheat stripe rust,15%triadimefon WP can be sprayed evenly at the dose of 1050 g/hm^(2)by a high-power sprayer in a sunny day.
文摘BACKGROUND We have previously demonstrated that the first wave of the coronavirus disease 2019(COVID-19)pandemic caused exacerbations in ulcerative colitis(UC)patients,probably through psychological and physical stress.However,successive waves of the COVID-19 pandemic continuously followed the first.The effects of this chronic stress on the disease condition in UC patients are of interest.AIM To clarify the effect of chronic stress from COVID-19 on disease condition in patients aggravated after the first wave.METHODS Our previous study investigated 289 consecutive UC outpatients treated in one center during March and April 2020,the period of the first wave of the COVID-19 pandemic.In this study,an identical group of 289 UC patients was evaluated using UC-disease activity index(UC-DAI),endoscopic mucosal appearance score,and Matts pathological grade scoring.RESULTS Of the 289 UC patients included in the study in 2020,10 patients dropped out as of 2021 and another 11 patients dropped out as of 2022,making three groups for 2020,2021 and 2022.No significant differences in characteristics were found among the three groups.UC-DAI scores had aggravated during the period of the first wave of the COVID-19 pandemic,but significantly recovered in 2021 and remained stable in 2022.Matts grade scores significantly recovered in 2021 from those in 2020 and remained stable in 2022.CONCLUSION Disease activity of UC patients recovered in 2021 and remained stable in 2022,aggravated by the stress of the first wave of COVID-19 in 2020 despite persistence of the pandemic.
文摘Background: Idiopathic Bullous Pemphigoid (IBP) is a rare blistering autoimmune disease. Its morbidity and mortality have remained high owing to complications of extensive skin involvement as well as its conventional steroid therapy. We reviewed the medical literature and found indicators of an autoimmune etiology for its pathogenesis triggering genetically predisposed patients. Objective: to evaluate, prospectively, the role of Rituximab (R) therapy in its persistent, severe and extensive form. Patients and methods: A total of 12 patients, with disease duration of 6 ± 1 months, were treated with yearly R infusions (1 g followed by 1 g 2 weeks later). Results: Significant clinical improvement was achieved as documented by decrease in total score of Bullous Pemphigoid Disease Area Index from 60 ± 3 to 6 ± 2 that persisted for 26 ± 11 months of follow up. Moreover, IBP autoantibodies (anti-BP 180 and anti-320 IgG) levels fell from to 91 ± 3 and 81 ± 2 to 8 ± 2 and 9 ± 2, respectively. Conclusions: R is a safe and effective treatment for severe IBP and such response further confirms its autoimmune pathogenesis.

文摘Objective:To assess the relationship between the severity of atopic dermatitis(AD)in children of varying weight categories and their serum 25-hydroxyvitamin D[25(OH)D]levels.Methods:The study population comprised 899 patients with AD and 854 age-and sex-matched controls.The Mann-Whitney U test and Kruskal-Wallis H tests were used to assess differences between groups,and Spearman correlation analysis was used to test correlation.Results:The 25(OH)D level in the AD group was M(Q_(25),Q_(75)),24.0(19.7,28.4)ng/mL,which was significantly lower than the control group(26.4[23.6,29.9]ng/mL;Z=-3.34,P=0.001).25(OH)D levels in children with AD were negatively correlated with body mass index(r=-0.30,P<0.001),Severity scoring of Atopic Dermatitis(SCORAD;r=-0.14,P<0.001),total immunoglobulin E(r=-0.13,P<0.001),and eosinophil(r=-0.08,P=0.017).There were statistically significant differences in 25(OH)D(H=18.46,P<0.001),total immunoglobulin E(H=9.13,P=0.010),eosinophil(H=67.17,P<0.001),and SCORAD(H=10.49,P=0.005)among groups with different body mass index classification.The 25(OH)D levels were 22.3(17.5,27.1)ng/mL in the overweight AD group and 22.3(17.6,25.7)ng/mL in the obese AD group,which were significantly lower than those in the normal-weight AD group(24.7[20.4,25.5]ng/mL;P=0.003,P=0.004).25(OH)D levels were negatively correlated with SCORAD in obese AD patients(r=-0.25,P=0.010).Conclusion:Vitamin D insufficient or deficient is obvious in children AD patients.The 25(OH)D levels in the overweight/obese AD group are significantly lower than those in the normal-weight AD group.Vitamin D level is negatively correlated with SCORAD in obese children with AD.
文摘Objective:To evaluate the effects of rituximab versus mycophenolate mofetil or cyclophosphamide as control in lupus nephritis by meta-analysis.Methods:A systematic search was carried out up to January 2022,obtaining 7 studies involving 645 participants with lupus nephritis at the commencement of the investigation;198 of them were treated with rituximab,while 447 were treated with mycophenolate mofetil or cyclophosphamide.We determined the odds ratio(OR)and mean difference(MD)with 95%confidence index(CI)to compare rituximab’s efficacy to that of mycophenolate mofetil or cyclophosphamide as control in lupus nephritis using random-or fixed-effects model by dichotomous or continuous techniques.Results:The rituximab group showed significantly higher complete renal remission rate(OR=2.52;95%CI 1.30-4.91,P=0.006)and total renal remission rates(OR=2.22;95%CI 1.36-3.63,P=0.001)than the control group.However,there was no significant difference in terms of end Systemic Lupus Erythematosus Disease Activity Index(SLEDAI)score(MD-1.16;95%CI-2.88-0.57,P=0.19),proteinuria(MD-0.31;95%CI-0.70-0.09,P=0.013),and serum creatinine(MD 0.01;95%CI-0.04-0.07,P=0.64)between the rituximab group and the control.Conclusion:Rituximab exhibited significantly greater complete renal remission rate and total renal remission rates,with no significant difference in terms of shorter-end SLEDAI,proteinuria,and serum creatinine,compared with the control in individuals with lupus nephritis.
文摘AIM: To suspect laryngopharyngeal reflux(LPR) in patients with ocular surface disease(OSD). METHODS: The present study evaluated a group of subjects with OSD assessing the Ocular Surface Disease Index(OSDI) and the Reflux Symptom Index(RSI) to detect patients with suspected LPR and define a possible relationship between tests.RESULTS: Two hundred and ninety subjects(175 females, mean age: 60.41±15.68y) were consecutively visited at ophthalmologist offices. One hundred and one(34%) patients had pathological RSI(〉13) and consequently a suspected LPR.CONCLUSION: The current study shows that suspected LPR may be common(34%) in patients with OSD and a suspected LPR may be considered in OSD patients when RSI score is 〉13 and OSDI score is 〉42.
文摘AIM:To evaluate the quantitative and qualitative results of the noninvasive tear film break-up time(NI-BUT)test and investigate the predictive ability of the new NIBUT parameter in discriminating between normal Ocular Surface Disease Index(OSDI;scores≤12)and abnormal OSDI(scores≥13).METHODS:A total of 341 eyes of 341 volunteers who applied for routine eye outpatient control were included in the prospective study.All participants'noninvasive first tear film break-up time(NIF-BUT),noninvasive average tear film break-up time(NIAvg-BUT)and average value of the first three break-up time(A3F-BUT)were analyzed.A3F-BUT,the new NI-BUT parameter,is calculated by adding the NIF-BUT value to the 2^(nd )break-up time value that has a difference of at most 1 second from the NIF-BUT value and to the 3^(rd) break-up time and then dividing the respective sum by 3.Receiver operating characteristic(ROC)curve and forward logistic regression analyses were performed to determine the parameter that had the best predictive ability between the OSDI groups.RESULTS:The NI-BUT values of 255 eyes of 255 volunteers included in the study were analyzed statistically.The mean NIF-BUT,NIAvg-BUT,and A3F-BUT values were calculated as 5.3±3.0,8±3.1,and 5.8±3.0 seconds,respectively.All three parameters were found to be significantly lower in the abnormal OSDI group(P=0.014,0.034,and 0.011,respectively).The area under the curve(AUC)of the A3F-BUT to predict abnormal OSDI was AUC=0.625(0.529-0.720),P=0.011 and NIF-BUT was AUC=0.599(0.502-0.696),P=0.043.The A3F-BUT parameter and NIF-BUT parameters were found to be significantly efficient in discriminating abnormal OSDI.CONCLUSION:The new parameter for the NI-BUT test has more predictive ability in the discrimination of OSDI groups.

文摘The control effect of microbial fertilizer on eggplant verticillium wilt was studied through investigation of disease index and diseased plant rate. The reiults showed that the disease index and diseased plant rate of eggplant verticillium wilt were the lowest in the plots with substrate treatment and root-irrigation treatnent. The control effects in the plots with substrate treatment were higher than those in the plots with only root irrigation treatment. Moreover, higher concentration of microbial fertilizer resulted in better control effect and higher yield. Thus, the microbial fertilizer had a broad application prospect.

文摘[Objective] The paper was to explore safe fungicides with high efficiency and long persistence against eucalyptus purple blotch. [Method]10%Difenoconazole WG,500 g /L thiophanate-methyl SC and 50% carbendazim WP were evaluated through experiment in forest,and clear water was used as CK. [Result]Three fungicides all had relatively good control effect against eucalyptus purple blotch. Most eucalyptus trees were able to restore growth and sprout new shoots after continuous three times of administration with the interval of 10 d. 10% Difenoconazole WG possessed the best control effect against eucalyptus purple blotch,with the disease index of 25. 24 and the control effect of 40. 24%; followed by 500 g /L thiophanate-methyl SC 600 times dilution,with the disease index of 27. 09 and the control effect of 35. 87%; 50% carbendazim WP 500 times dilution had the poorest control effect,with the disease index of 32. 21 and the control effect of23. 74%. The disease index of CK was 42. 24. [Conclusion]The above fungicides were safe to eucalyptus,and could be used to control eucalyptus purple blotch.
文摘AIM To evaluate the role of oral curcumin in inducing clinical remission in patients with mild to moderate ulcerative colitis(UC).METHODS A prospective randomized double-blind placebo-controlled trial comparing the remission inducing effect of oral curcumin and mesalamine 2.4 g with placebo and mesalamine 2.4 g in patients of ulcerative colitis with mild to moderate severity was conducted from January 2003 to March 2005. The included patients received 1 capsule thrice a day of placebo or curcumin(150 mg) for 8 wk. Patients were evaluated clinically and endoscopically at 0,4 and 8 wk. The primary outcome was clinical remission at 8 wk and secondary outcomes were clinical response, mucosal healing and treatment failure at 8 wk. The primary analysis was intention to treat worst case scenario(ITT-WCS).RESULTS Of 300 patients with UC, 62 patients(curcumin: 29, placebo: 33) fulfilled the inclusion criteria and were randomized at baseline. Of these, 21 patients did not complete the trial, 41 patients(curcumin: 16, placebo: 25) finally completed 8 wk. There was no significant difference in rates of clinical remission(31.3% vs 27.3%, P = 0.75), clinical response(20.7% vs 36.4%, P = 0.18), mucosal healing(34.5% vs 30.3%, P = 0.72), and treatment failure(25% vs 18.5%, P = 0.59) between curcumin and placebo at 8 wk.CONCLUSION Low dose oral curcumin at a dose of 450 mg/d was ineffective in inducing remission in mild to moderate cases of UC.
