Serum bio-chemical indices, haematological indices and blood electrolytes are critical physiological indices which have health implications on the diagnosis, prognosis and treatment of livestock diseases especially in animals bred under different management systems. It is important to stress that cascades of parameters of both genetic and non-genetic origin greatly have direct and in-direct health implications on serum bio-chemical indices and blood electrolytes in livestock animals and subsequently on their health/ production performances. Laboratory blood tests would be a vital tool to help detect any deviation from normal state of wellbeing in animals. Therefore, this review intends to provide base line information to establish certain haematological and serum bio-chemical indices as standard references which can be employed as alternative therapy for diagnosis, prognosis and treatment of cascades of diseases plaguing livestock animals bred under different management systems especially under the harsh condition of the tropics. Hence, it is important to establish standard values for the various blood and serum bio-chemical indices base on parameters of non-genetic origin;age, sex, physiological state, stress level, management systems, medication, health status, nutrition, hormone, climate, etc. and genetic parameters which include the breed and genotype of the animal among others obviously affect the blood and serum profile of healthy animal which subsequently influence their production performance and efficiency.展开更多

[Method] Totally 500 individuals of 1-day-old Guangxi Partridge chickens were randomly divided into five groups, five replicates each group and 20 chicks each replicate. Groups A, B and C were treatment groups supplemented with 0.70%, 0.35% and0.175% P. felterrae extracts in the basal diet, respectively; group D was a medical control group supplemented with 0.01% colistin sulfate premix in the basal diet; and group E was a control group with basal diet. Serum samples were collected from 10 chickens in each group at 21, 35 and 49 days of age, to analyze the biochemical and immune indexes. [Result] It had no significant impact on serum TP and GLU contents of chickens by adding different levels of P. felterrae extracts in the basal diet(P 〉0.05). However, at 21 and 35 days of age, the TBILI content of chickens in groups A, B and C were extremely lower or significantly lower than that in group E( P〈0.01; P〈0.05). At 35 days of age, the serum AKP activities in groups A, B and C were extremely higher than that in group E(P〈0.01), and the serum GOT activities at 21 and 35 days of age in group C were significantly higher than that in group E(P〈0.05). At 49 days of age, the serum Ig G content in groups A, B and C and the IL-2 content in group B and group C were significantly lower or extremely lower than that in group E( P〈0.05; P〈0.01); the T-AOC content in group B was significantly higher than that in group E(P〈0.05); the GSH content in groups A, B and C were significantly higher than that in group E( P〈0.05). Adding different levels of P. felterrae extracts in the diet significantly decreased the TBILI content, reduced the Ig G, IL-2 and IL-6 contents, and improved the AKP and GOT activities and the T-AOC and GSH contents of Guangxi Partridge chicken. [Conclusion] Adding 0.35% P. felterrae extracts in the basal diet received the best effort.展开更多

The serious complications are major risk factors for poor longterm surgical outcome. Studies have reported an association between early postoperative prognostic nutritional index(PNI) and prediction of severe complications after abdominal surgery. However, there have been no studies on the use of early postoperative PNI for predicting serious complications following PD.AIM To analyze the risk factors and early postoperative PNI for predicting severe complications following PD.METHODS We retrospectively analyzed 238 patients who underwent PD at our hospital between January 2007 and December 2017. The postoperative complications were classified according to the Dindo-Clavien classification. Grade Ⅲ-Ⅴ postoperative complications were classified as serious. The risk factors for serious complications were analyzed by univariate analysis and multivariate logistic regression analysis.RESULTS Overall complications were detected in 157 of 238 patients(65.9%) who underwent PD. The grade Ⅲ-Ⅴ complication rate was 26.47%(63/238 patients).The mortality rate was 3.7%(9/238 patients). Multivariate logistic regression analysis revealed that preoperative serum albumin [odds ratio(OR): 0.883, 95%confidence interval(CI): 0.80-0.96; P < 0.01] and PNI on postoperative day 3 <40.5(OR: 2.77, 95%CI: 1.21-6.38, P < 0.05) were independent factors associated with grade Ⅲ-Ⅴ postoperative complications.CONCLUSION Perioperative albumin is an important factor associated with serious complications following PD. Low early postoperative PNI(< 40.5) is a predictor for serious complications.展开更多

We evaluated the associations of age, body mass index (BMI) and serum lipid profile with serum PSA level in 6774 Chinese men (aged 20-49 years) who received a routine health examination. Eligible men were classified into 10-year age groups, BMI was categorized as underweight (〈18.5), normal (18.5-22.9), overweight (23.0-24.9), obese (25.0-29,9) and very obese (〉30) according to the redefined World Health Organization (WHO) criteria for the Asia-Pacific region. PSA levels were compared among groups as well, In multiple linear regression analysis, PSA was positively correlated with age (P〈0.0001). Negative correlations existed between PSA and BMI (P〈0.0001) and triglyceride level (P=0.01). No relationship could be found between PSA and serum cholesterol (P=0.711) or high-density lipoprotein (HDL; P =0.665). In addition, we found that serum PSA levels increased with age and decreased with BMI. Our study demonstrates that age, BMI and triglyceride levels influence the PSA level in men 〈50 years of age.展开更多

Geese were fed the diets containing 4.29%, 5.29% and 6.29 % crude fiber, respectively. The experiment lasted 35 d.[Result] Final weight and daily gain of 5.29 %CF group were significantly higher than those of 6.29 % CF group(P<0.05);Feed intake was markedly higher than those of 4.29% and 6.29 % CF groups(P<0.05);Feed gain ratio was significantly lower than that of 6.29 % CF group(P<0.05). Compared with 4.29% and 6.29 % CF groups, serum albumin concentrations of 5.29 % CF group increased significantly(P<0.05), while serum total protein and globin contents were higher(P>0.05), but serum uric acid level was lower(P>0.05).[Conclusion] 5.29 % crude fiber could lead to higher growth performance of Dingan geese.展开更多

Methods The serum concentration of leptin in 39 patients with CHF (14 in cardiac function class Ⅱ , 21 in class Ⅲ, 4 in classⅣ , NYHA) and in 46 patients with cardiac function class Ⅰ (NYHA) were assessed by radioimmunoassay. Results The serum concentration of leptin were 9.018±4.519 μg/l in CHF group (cardiac function class Ⅱ 11.492±5.649 μg/l, class Ⅲ 7.763±3.321 μg/l, class Ⅳ 6.100±2.657 μg/l); 11.674± 6.911 μg/l in class Ⅰ group. The serum concentrations of leptin were significantly lower in CHF group, as compared with class Ⅰ group (P〈 0.05). Moreover, the decrease of serum leptin concentration was significantly correlated with the decreased serum concentrations of total cholesterol, triglyceride, body mass index and left ventricular ejection fraction in CHF group, respectively (P 〈 0.05). Conclusions The significance of the decrease in serum leptin in CHF patients needs further study.展开更多

Ltd. feedlot Yining Tuogelake village used tethered and scattered feeding methods to conduct fattening young Xinjiang brown cattle experiment. [Method] The 16-month-old young Xinjiang brown bulls were se- lected totaling 68 heads, divided into scattered group and tethered group. Male claves were taken as test subjects from October to February of following year and body conformation linear evaluation were made, followed by measurement of body size indexes and Regular collection of Blood samples. [Result] In the two feeding ways, scattered group feeding improved the ADG of youth Xinjiang brown cattle bull calf (P〈0.01), and the whole calf ADG 845.58g was significantly higher than that in tethered group at 619.11g, increasing by 36.58%; furthermore, scattered group in the December, January and February average daily weight gain was significantly higher compared with the tethered group at 13.61%, 32.32%, 53.47%, respectively. Scattered group feeding significantly increased the young calf serum phosphorus content (P〈0.01), higher than the tethered group at 0.62%, 7.89%, 14.29% in February, December and January respectively. But the tethered feeding young cattle serum phosphorus content gradually declined. Of the two groups, male calf serum calcium content had little effects on the serum calcium with insignificant difference (P〉0.05). Bulls by scattered feeding method was proved faster and better in the whole growth period, in terms of body height, body length, circumference, leg cir- cumference, rump length, waist high, sciatic wide, hip width basically in the contin- ued growth trend. [Conclusion] Scattered feeding can significantly improve the young Xinjiang brown cattle's daily gain, and accelerate the body height, heart girth and body length etc body growth. What's more, scattered feeding serum calcium and phosphorus content are significantly higher than tethered feeding.展开更多

At 42 days of age, the serum F content was markedly higher in the three high F groups than that in the control group. From 28 to 42 days of age, the contents of serum total protein (TP) and albumin (ALB) were significantly lower in the three high F groups. From 14 to 42 days of age, the activities of alkaline phosphatase (ALP), alanine aminotransferase (ALT) and the creatinine (Crea) contents in the serum showed a marked increase in the three high F groups;aspartate aminotransferase (AST) activity and uric acid (Ua) content were significantly increased, and a significant increase in the content of malondialdehyde (MDA) along with marked decreases in the activities of total superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px), catalase (CAT), the glutathione (GSH) content and the ability to inhibit hydroxyl radical were observed in the high F groups II and III. In conclusion, F has accumulated in the blood circulatory system and dietary F in the range of 800 - 1200 mg/kg could significantly induce abnormalities of bone, liver and kidney, inhibit the synthesis of protein, enhance lipid peroxidation and disturb the antioxidative system of broiler chickens.展开更多

All patients completed a comprehensive questionnaire survey and underwent abdominal ultrasound examination and a blood test. NAFLD was diagnosed using ultrasonography after other etiologies were excluded. Logistic regression and restricted cubic spline model were conducted to evaluate the relationship of UHR with NAFLD risk.Results The multivariable adjusted odds ratio(95% confidence interval, CI) for NAFLD in the highest versus lowest quartile of UHR was 3.888(2.324–6.504). In analyses stratified by sex and age, we observed significant and positive associations between UHR and the risk of NAFLD in each subgroup. In analyses stratified by body mass index(BMI), a significant and positive association was found only in individuals with a BMI of ≥ 24 kg/m2. Our dose-response analysis indicated a linear positive correlation between UHR and the risk of NAFLD.Conclusion UHR is positively associated with the risk of NAFLD and may serve as an innovative and noninvasive marker for identifying individuals at risk of NAFLD.展开更多

文摘Serum bio-chemical and haematological indices constitute important panels in the diagnosis, prognosis and treatment of livestock diseases via the investigations of myriads of parameters influencing these blood and serum bio-chemical indices. Serum bio-chemical indices, haematological indices and blood electrolytes are critical physiological indices which have health implications on the diagnosis, prognosis and treatment of livestock diseases especially in animals bred under different management systems. It is important to stress that cascades of parameters of both genetic and non-genetic origin greatly have direct and in-direct health implications on serum bio-chemical indices and blood electrolytes in livestock animals and subsequently on their health/ production performances. Laboratory blood tests would be a vital tool to help detect any deviation from normal state of wellbeing in animals. Therefore, this review intends to provide base line information to establish certain haematological and serum bio-chemical indices as standard references which can be employed as alternative therapy for diagnosis, prognosis and treatment of cascades of diseases plaguing livestock animals bred under different management systems especially under the harsh condition of the tropics. Hence, it is important to establish standard values for the various blood and serum bio-chemical indices base on parameters of non-genetic origin;age, sex, physiological state, stress level, management systems, medication, health status, nutrition, hormone, climate, etc. and genetic parameters which include the breed and genotype of the animal among others obviously affect the blood and serum profile of healthy animal which subsequently influence their production performance and efficiency.

文摘[Objective] This trial was to investigate the effect of dietary Picria felterrae Lour extracts on serum biochemical indexes and immune function of Guangxi Partridge chickens. [Method] Totally 500 individuals of 1-day-old Guangxi Partridge chickens were randomly divided into five groups, five replicates each group and 20 chicks each replicate. Groups A, B and C were treatment groups supplemented with 0.70%, 0.35% and0.175% P. felterrae extracts in the basal diet, respectively; group D was a medical control group supplemented with 0.01% colistin sulfate premix in the basal diet; and group E was a control group with basal diet. Serum samples were collected from 10 chickens in each group at 21, 35 and 49 days of age, to analyze the biochemical and immune indexes. [Result] It had no significant impact on serum TP and GLU contents of chickens by adding different levels of P. felterrae extracts in the basal diet(P 〉0.05). However, at 21 and 35 days of age, the TBILI content of chickens in groups A, B and C were extremely lower or significantly lower than that in group E( P〈0.01; P〈0.05). At 35 days of age, the serum AKP activities in groups A, B and C were extremely higher than that in group E(P〈0.01), and the serum GOT activities at 21 and 35 days of age in group C were significantly higher than that in group E(P〈0.05). At 49 days of age, the serum Ig G content in groups A, B and C and the IL-2 content in group B and group C were significantly lower or extremely lower than that in group E( P〈0.05; P〈0.01); the T-AOC content in group B was significantly higher than that in group E(P〈0.05); the GSH content in groups A, B and C were significantly higher than that in group E( P〈0.05). Adding different levels of P. felterrae extracts in the diet significantly decreased the TBILI content, reduced the Ig G, IL-2 and IL-6 contents, and improved the AKP and GOT activities and the T-AOC and GSH contents of Guangxi Partridge chicken. [Conclusion] Adding 0.35% P. felterrae extracts in the basal diet received the best effort.
文摘BACKGROUND Pancreaticoduodenectomy(PD) is a complex surgical procedure with a high morbidity rate. The serious complications are major risk factors for poor longterm surgical outcome. Studies have reported an association between early postoperative prognostic nutritional index(PNI) and prediction of severe complications after abdominal surgery. However, there have been no studies on the use of early postoperative PNI for predicting serious complications following PD.AIM To analyze the risk factors and early postoperative PNI for predicting severe complications following PD.METHODS We retrospectively analyzed 238 patients who underwent PD at our hospital between January 2007 and December 2017. The postoperative complications were classified according to the Dindo-Clavien classification. Grade Ⅲ-Ⅴ postoperative complications were classified as serious. The risk factors for serious complications were analyzed by univariate analysis and multivariate logistic regression analysis.RESULTS Overall complications were detected in 157 of 238 patients(65.9%) who underwent PD. The grade Ⅲ-Ⅴ complication rate was 26.47%(63/238 patients).The mortality rate was 3.7%(9/238 patients). Multivariate logistic regression analysis revealed that preoperative serum albumin [odds ratio(OR): 0.883, 95%confidence interval(CI): 0.80-0.96; P < 0.01] and PNI on postoperative day 3 <40.5(OR: 2.77, 95%CI: 1.21-6.38, P < 0.05) were independent factors associated with grade Ⅲ-Ⅴ postoperative complications.CONCLUSION Perioperative albumin is an important factor associated with serious complications following PD. Low early postoperative PNI(< 40.5) is a predictor for serious complications.
文摘This study is to assess the potential factors that could affect the serum prostate-specific antigen (PSA) level in healthy younger men. We evaluated the associations of age, body mass index (BMI) and serum lipid profile with serum PSA level in 6774 Chinese men (aged 20-49 years) who received a routine health examination. Eligible men were classified into 10-year age groups, BMI was categorized as underweight (〈18.5), normal (18.5-22.9), overweight (23.0-24.9), obese (25.0-29,9) and very obese (〉30) according to the redefined World Health Organization (WHO) criteria for the Asia-Pacific region. PSA levels were compared among groups as well, In multiple linear regression analysis, PSA was positively correlated with age (P〈0.0001). Negative correlations existed between PSA and BMI (P〈0.0001) and triglyceride level (P=0.01). No relationship could be found between PSA and serum cholesterol (P=0.711) or high-density lipoprotein (HDL; P =0.665). In addition, we found that serum PSA levels increased with age and decreased with BMI. Our study demonstrates that age, BMI and triglyceride levels influence the PSA level in men 〈50 years of age.

文摘Objectives To investigate the relationship of serum leptin concentration with the lipids and body mass index (BMI) in patients with chronic congestive heart failure(CHF). Methods The serum concentration of leptin in 39 patients with CHF (14 in cardiac function class Ⅱ , 21 in class Ⅲ, 4 in classⅣ , NYHA) and in 46 patients with cardiac function class Ⅰ (NYHA) were assessed by radioimmunoassay. Results The serum concentration of leptin were 9.018±4.519 μg/l in CHF group (cardiac function class Ⅱ 11.492±5.649 μg/l, class Ⅲ 7.763±3.321 μg/l, class Ⅳ 6.100±2.657 μg/l); 11.674± 6.911 μg/l in class Ⅰ group. The serum concentrations of leptin were significantly lower in CHF group, as compared with class Ⅰ group (P〈 0.05). Moreover, the decrease of serum leptin concentration was significantly correlated with the decreased serum concentrations of total cholesterol, triglyceride, body mass index and left ventricular ejection fraction in CHF group, respectively (P 〈 0.05). Conclusions The significance of the decrease in serum leptin in CHF patients needs further study.
文摘BACKGROUND Conventional five-port laparoscopic surgery,the current standard treatment for colorectal carcinoma(CRC),has many disadvantages.AIM To assess the influence of reduced-port laparoscopic surgery(RPLS)on perioperative indicators,postoperative recovery,and serum inflammation indexes in patients with CRC.METHODS The study included 115 patients with CRC admitted between December 2019 and May 2023,52 of whom underwent conventional five-port laparoscopic surgery(control group)and 63 of whom underwent RPLS(research group).Comparative analyses were performed on the following dimensions:Perioperative indicators[operation time(OT),incision length,intraoperative blood loss(IBL),and rate of conversion to laparotomy],postoperative recovery(first postoperative exhaust,bowel movement and oral food intake,and bowel sound recovery time),serum inflammation indexes[high-sensitivity C-reactive protein(hs-CRP),tumor necrosis factor-α(TNF-α),and interleukin-6(IL-6)],postoperative complications(anastomotic leakage,incisional infection,bleeding,ileus),and therapeutic efficacy.RESULTS The two groups had comparable OTs and IBL volumes.However,the research group had a smaller incision length;lower rates of conversion to laparotomy and postoperative total complication;and shorter time of first postoperative exhaust,bowel movement,oral food intake,and bowel sound recovery;all of which were significant.Furthermore,hs-CRP,IL-6,and TNF-αlevels in the research group were significantly lower than the baseline and those of the control group,and the total effective rate was higher.CONCLUSION RPLS exhibited significant therapeutic efficacy in CRC,resulting in a shorter incision length and a lower conversion rate to laparotomy,while also promoting postoperative recovery,effectively inhibiting the inflammatory response,and reducing the risk of postoperative complications.

文摘[Objective] In the Xinjiang new era from October 2012 to February 2013, agricultural and animal husbandry Co. Ltd. feedlot Yining Tuogelake village used tethered and scattered feeding methods to conduct fattening young Xinjiang brown cattle experiment. [Method] The 16-month-old young Xinjiang brown bulls were se- lected totaling 68 heads, divided into scattered group and tethered group. Male claves were taken as test subjects from October to February of following year and body conformation linear evaluation were made, followed by measurement of body size indexes and Regular collection of Blood samples. [Result] In the two feeding ways, scattered group feeding improved the ADG of youth Xinjiang brown cattle bull calf (P〈0.01), and the whole calf ADG 845.58g was significantly higher than that in tethered group at 619.11g, increasing by 36.58%; furthermore, scattered group in the December, January and February average daily weight gain was significantly higher compared with the tethered group at 13.61%, 32.32%, 53.47%, respectively. Scattered group feeding significantly increased the young calf serum phosphorus content (P〈0.01), higher than the tethered group at 0.62%, 7.89%, 14.29% in February, December and January respectively. But the tethered feeding young cattle serum phosphorus content gradually declined. Of the two groups, male calf serum calcium content had little effects on the serum calcium with insignificant difference (P〉0.05). Bulls by scattered feeding method was proved faster and better in the whole growth period, in terms of body height, body length, circumference, leg cir- cumference, rump length, waist high, sciatic wide, hip width basically in the contin- ued growth trend. [Conclusion] Scattered feeding can significantly improve the young Xinjiang brown cattle's daily gain, and accelerate the body height, heart girth and body length etc body growth. What's more, scattered feeding serum calcium and phosphorus content are significantly higher than tethered feeding.

文摘Objective The relationship between serum uric acid(SUA)levels and glycemic indices,including plasma glucose(FPG),2-hour postload glucose(2 h-PG),and glycated hemoglobin(HbA1 c),remains inconclusive.We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.Methods The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study.A total of 105,922 community-dwelling adults aged≥40 years underwent the oral glucose tolerance test and uric acid assessment.The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.Results A total of 30,941 men and 62,361 women were eligible for the current analysis.Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels,but with different inflection points in men and women.The thresholds for FPG,2 h-PG,and HbA1 c for men and women were 6.5/8.0 mmol/L,11.0/14.0 mmol/L,and 6.1/6.5,respectively(SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes,while the inflection points were reached earlier in men than in women.
文摘[ Objective] TO further explore the mechanism of retained fetal membrane (RFM) of dairy cows in Qinghai Province. [ Methed] As many as 15 dairy cows with retained fetal placenta and 15 without retained fetal placenta were selected. The serum concentrations of eight metal ions, namely, potassium, sodium, calcium, magnesium, copper, iron, zinc and manganese at parturition and 12 h post partum were determined by atomic absorption spectrometry. The anti-oxidative indexes at parturition were determined by UV-1601 doub|e-beam visib|e spectrophotometer. ~=- sultl In the dairy cows with retained fetal placenta, the concentrations of calcium, magnesium, copper, zinc and manganese were decreased signif- icantly ( P 〈 0.05) ; that of iron was increased significantly ( P 〈 0.01 ) ; those of potassium and sodium did not change greatly; the activities of su- peroxide dismutase and glutathione peroxidase were decreased significantly ( P 〈 0.01 ) ; and the MDA content was increased significantly ( P 〈 0.05). However, the concentrations of the eight metal ions and anti-oxidative indexes did not change in the dairy cows without retained fetal placen- ta, [ CondusionJ The RFM of dairy cows has some relationships with the serum concentrations of metal ions and antioxidation.
文摘The aim of this study was to investigate the effects of high dietary fluoride (F) on serum biochemistry and oxidative damage in broiler chickens. 280 one-day-old healthy avian broiler chickens were randomly allotted into four equal groups and fed with a corn-soybean basal diet containing 22.6 mg·F/kg (control group) or same basal diets supplemented with 400, 800, and 1200 mg·F/kg (high F groups I, II, and III) in the form of sodium fluoride for 42 days. At 42 days of age, the serum F content was markedly higher in the three high F groups than that in the control group. From 28 to 42 days of age, the contents of serum total protein (TP) and albumin (ALB) were significantly lower in the three high F groups. From 14 to 42 days of age, the activities of alkaline phosphatase (ALP), alanine aminotransferase (ALT) and the creatinine (Crea) contents in the serum showed a marked increase in the three high F groups;aspartate aminotransferase (AST) activity and uric acid (Ua) content were significantly increased, and a significant increase in the content of malondialdehyde (MDA) along with marked decreases in the activities of total superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px), catalase (CAT), the glutathione (GSH) content and the ability to inhibit hydroxyl radical were observed in the high F groups II and III. In conclusion, F has accumulated in the blood circulatory system and dietary F in the range of 800 - 1200 mg/kg could significantly induce abnormalities of bone, liver and kidney, inhibit the synthesis of protein, enhance lipid peroxidation and disturb the antioxidative system of broiler chickens.

文摘Objective The aim of this case-control study was to explore the association between serum uric acid to high density lipoprotein cholesterol ratio(UHR) and the risk of nonalcoholic fatty liver disease(NAFLD) in Chinese adults.Methods A total of 636 patients with NAFLD and 754 controls were enrolled from the Affiliated Hospital of Qingdao University, China, between January and December 2016. All patients completed a comprehensive questionnaire survey and underwent abdominal ultrasound examination and a blood test. NAFLD was diagnosed using ultrasonography after other etiologies were excluded. Logistic regression and restricted cubic spline model were conducted to evaluate the relationship of UHR with NAFLD risk.Results The multivariable adjusted odds ratio(95% confidence interval, CI) for NAFLD in the highest versus lowest quartile of UHR was 3.888(2.324–6.504). In analyses stratified by sex and age, we observed significant and positive associations between UHR and the risk of NAFLD in each subgroup. In analyses stratified by body mass index(BMI), a significant and positive association was found only in individuals with a BMI of ≥ 24 kg/m2. Our dose-response analysis indicated a linear positive correlation between UHR and the risk of NAFLD.Conclusion UHR is positively associated with the risk of NAFLD and may serve as an innovative and noninvasive marker for identifying individuals at risk of NAFLD.
文摘BACKGROUND Coronavirus disease 2019(COVID-19)has a spectrum of clinical syndromes with serious involvement of the lung and frequent effection of the liver and hemostatic system.Blood biomarkers are affordable,rapid,objective,and useful in the evaluation and prognostication of COVID-19 patients.AIM To investigate the association between aspartate transferase-to-platelet ratio index(APRI)and in-hospital mortality to develop a COVID-19 mortality prediction model.METHODS A multicenter cohort study with a retrospective design was conducted.Medical records of all consecutive adult patients admitted to Al-Azhar University Hospital(Assiut,Egypt)and Chest Hospital(Assiut,Egypt)with confirmed COVID-19 from July 1,2020 to October 1,2020,were retrieved and analyzed.The patient cohort was classified into the following two categories based on the APRI:(1)COVID-19 presenting with APRI≤0.5;and(2)COVID-19 presenting with APRI(>0.5 and≤1.5).The association between APRI and all-cause in-hospital mortality was analyzed,and the new model was developed through logistic regression analyses.RESULTS Of the 353 patients who satisfied the inclusion criteria,10%were admitted to the intensive care unit(n=36)and 7%died during the hospital stay(n=25).The median age was 40 years and 50.7%were male.On admission,49%had aspartate transferase-dominant liver injury.On admission,APRI(>0.5 and≤1.5)was independently associated with all-cause in-hospital mortality in unadjusted regression analysis and after adjustment for age and sex;after stepwise adjustment for several clinically relevant confounders,APRI was still significantly associated with all-cause inhospital mortality.On admission,APRI(>0.5 and≤1.5)increased the odds of mortality by fivetimes(P<0.006).From these results,we developed a new predictive model,the APRI-plus,which includes the four predictors of age,aspartate transferase,platelets,and serum ferritin.Performance for mortality was very good,with an area under the receiver operating curve of 0.90.CONCLUSION APRI-plus is an accurate and simplified prediction model for mortality among patients with COVID-19 and is associated with in-hospital mortality,independent of other relevant predictors.

The control group received conventional combined therapy, the observation group were given HBO treatment on the base of the control group, the inflammatory factors [C reactive protein (CRP), tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10)] and oxidative stress [malondialdehyde (MDA) and superoxide dismutase-1 (SOD-1)], endothelin (ET) and intracranial pressure (ICP) level changes of the two groups were observed and compared before and after treatment for 10 d in patients. Results: The levels of CRP, TNF-α, IL-6, MDA, ET and ICP in the treatment group and the control group were significantly lower than those in the same group before treatment, the difference was statistically significant (P<0.05), the CRP, TNF-α, IL-6, MDA, ET and ICP levels of the observation group after treatment were significantly lower than the control group after treatment (P<0.05);After treatment, IL-10 and SOD-1 levels of the two groups of patients were significantly increased than the same group before treatment (P<0.05), and both levels in the observation group after treatment was significantly higher than the control group after treatment (P<0.05).Conclusions: HBO treatment of severe brain injury patients with significant effect, can effectively reduce oxidative stress damage and inflammation, improve patients' endothelial cell function, reduce intracranial pressure, and has a certain clinical value.

文摘BACKGROUND Early screening for colorectal cancer(CRC)is important in clinical practice.However,the currently methods are inadequate because of high cost and low diagnostic value.AIM To develop a new examination method based on the serum biomarker panel for the early detection of CRC.METHODS Three hundred and fifty cases of CRC,300 cases of colorectal polyps and 360 cases of normal controls.Combined with the results of area under curve(AUC)and correlation analysis,the binary Logistic regression analysis of the remaining indexes which is in accordance with the requirements was carried out,and discriminant analysis,classification tree and artificial neural network analysis were used to analyze the remaining indexes at the same time.RESULTS By comparison of these methods,we obtained the ability to distinguish CRC from healthy control group,malignant disease group and benign disease group.Artificial neural network had the best diagnostic value when compared with binary logistic regression,discriminant analysis,and classification tree.The AUC of CRC and the control group was 0.992(0.987,0.997),sensitivity and specificity were 98.9%and 95.6%.The AUC of the malignant disease group and benign group was 0.996(0.992,0.999),sensitivity and specificity were 97.4%and 96.7%.CONCLUSION Artificial neural network diagnosis method can improve the sensitivity and specificity of the diagnosis of CRC,and a novel assistant diagnostic method was built for the early detection of CRC.
