The prevalence is between 5% - 30%. CVI is associated with older age, smoking, lower extremity trauma, presence of an arteriovenous shunt, and elevated estrogen levels. All patients should be initially treated with conservative management. Venoactive drugs like calcium dobesilate are useful. Objectives: The primary objective compared the clinical improvement in patients with CVI, grades 0 - 3 of the CEAP classification of chronic venous disease, produced by two formulations of calcium dobesilate: calcium dobesilate LP 1 g OD vs calcium dobesilate 500 mg BID, immediate release. The secondary objective assessed the side effects of both formulations. Method: All patients took one tablet and one capsule at 7 am, and one capsule at 7 pm, for 8 weeks. One group received dobesilate 1 g OD and the other group received dobesilate 500 md BID. They were evaluated after 15, 30 and 60 days of treatment, using the symptom evaluation scale. Results: In both groups, there was a significant decrease in the symptom score after 15 days. Four patients in the Dobesilate OD group: had adverse effects, which did not require suspension of treatment. In the BID dobesilate group, there was one therapeutic failure, and one case of gastric discomfort. Conclusions: Prolonged-release Calcium dobesilate 1 g OD is as effective as calcium dobesilate 500 mg BID for the treatment of patients with chronic venous insufficiency.展开更多

Prophylactic cervical cerclage is a surgical procedure performed between 11 and 14 weeks of gestation upon diagnosis of cervix insufficiency among pregnant women. Aims & Objectives: In this study, we aimed to evaluate the effectiveness of prophylactic cervical cerclage in comparison to other interventions to treat cervical insufficiency among pregnant women using a meta-analysis approach. Methods: We searched the three databases (Coachrane Library, PubMed, and MEDLINE) that were used for articles related to research aims by using MeSH keywords. The timeline of research was set from January 2015 to January 2024. The methodological quality assessment of included studies was performed by the Risk of Bias in Non-randomized Studies—of Interventions (ROBINS-I). A recent meta-analysis was conducted by using Review Manager 5.4.0 software. Results: About 441 research articles were extracted from three electronic databases and only 125 articles were assessed for eligibility criteria. Finally, 8 studies were included in the analysis for a recent meta-analysis. Six out of eight included retrospective or pilot studies were graded as having a moderate risk of bias, and two studies had low risk on the basis of owning bias. About 1008 pregnant women with cervical insufficiency were analyzed in a recent meta-analysis. By pooled analysis, it was evaluated that significant difference found in prolongation of delivery weeks (Mean difference = 1.05;Cl: 0.81 to 1.29: p > 0.00001), number of deliveries > 37 weeks (OR = 0.59;Cl: 0.19 to 1.84: p > 0.006), and preterm birth (OR = 0.73;Cl: 0.42 to 1.28: p > 0.50) among pregnant women receiving prophylactic cervical cerclage as compared to other treatment strategies. Conclusion: Recent meta-analysis suggested the prophylactic cervical cerclage reduces the rates of preterm birth, abortion rates, number of deliveries > 37 weeks, and other complications as compared to the other cervical cerclage types and conservative treatments.展开更多

Many patients referred for surgery already have a poor clinical condition and an advanced New York Heart Association functional class. There is no consensus on the optimal surgical technique for this condition, including on whether to perform the procedure on a beating or an arrested heart and whether to perform valve repair or replacement. Methods: We analyzed four case series between 2015 and 2022 in which patients with secondary tricuspid regurgitation (TR) underwent valve repair on a beating heart and right atrial plication for a dilated right atrium. The TRI-SCORE was calculated for each patient. Results: All patients experienced a favorable postoperative course with significant improvements in heart failure symptoms. TR was markedly reduced;however, in one patient with concomitant mitral regurgitation (MR) and a high TRI-SCORE, MR worsened postoperatively. This patient later died from unknown causes due to multiple comorbidities in the late phase. Conclusions: Tricuspid valve repair on a beating heart was effective for improving the cardiac function, and the TRI-SCORE proved useful as a preoperative risk assessment tool. The underlying mechanism by which TR exacerbates MR requires further investigation.展开更多

Case Presentation: A 48-year-old female patient with hypertension and progressive weight gain, the clinical signs of hypercorticism motivated a hormonal workup revealing an independent ACTH Cushing’s syndrome: with urinary free cortisol (UFC) at 649 nmol/24h (4× normal), adrenocorticotropin hormone (ACTH) at 1.5 ng/l. The rest of the hormonal workup was not performed due to a lack of financial means. An Adrenal CT scan showed a 4 cm right adrenal adenoma. The patient underwent a right adrenalectomy with an adrenal adenoma on pathological examination. The contralateral side was normal. The patient was treated with hydrocortisone 30 mg/d for 6 weeks then 15 mg/d, during the monitoring we noted a persistence of the adrenal insufficiency for now 4 years. Basal cortisol levels during follow-up were very low (<3 μg/dl) ruling out the need for synacthen stimulation tests. Conclusion: Adrenal cortisol tumors are recognized by suppression, the duration of hypothalamic-pituitary-adrenal axis suppression is variable from 11 to 60 months depending on the series, which depends on the duration, severity of hypercortisolism, tumor size and other unknown factors. A longer follow-up of these patients is necessary to look for recovery of the contralateral adrenal gland.展开更多

文摘Objective To analyze whether association of edge to edge valve repair with artificial ring annuloplasty would result in better results in patients with severe tricuspid regurgitation (TR) . Methods From April,2001 to May, 2010,41 patients underwent tricuspid valve repair to treat severe TR were studied. Twenty-one patients were done artificial ring annuloplasty alone (group R) and twenty patients were done artificial ring annuloplasty associated with edge to edge valve repair (group E) . All the
文摘AIM:To compare and analyse the diagnostic efficacy of the College of Optometrists Vision Development Quality of Life Questionnaire(COVD-QOL)and the Convergence Insufficiency Symptom Survey(CISS)in detecting convergence insufficiency and to compare their diagnostic value in clinical applications.METHODS:Using the diagnostic test method,62 adult patients with convergence insufficiency(age:24.74±3.75y)and 62 normal participants(age:23.61±3.13y)who visited the Optometry Clinic of West China Hospital of Sichuan University from April 2021 to January 2023 were included.All subjects completed the CISS and COVD-QOL.Statistical analysis of the sensitivity and specificity of the CISS and COVD-QOL and comparison and joint experimental analysis of their diagnostic efficacy were performed.RESULTS:The sensitivity of the CISS and COVD-QOL for convergence insufficiency was 64.5%and 71.0%,respectively,while the specificity was 96.8%and 67.7%,respectively.Compared to the CISS alone,the combination of the CISS and COVD-QOL demonstrated lower sensitivity and specificity.The areas under the receiver operating characteristic curve of CISS,COVD-QOL and CISS combined with COVD-QOL were 0.806,0.694 and 0.782,respectively.CONCLUSION:Considering the low sensitivity of the CISS and the low specificity of the COVD-QOL,it is recommended to supplement these questionnaires with other screening tests for the detection of convergence insufficiency.

文摘Pain is a common complaint among patients seeking medical care.If left un-treated,pain can become chronic,significantly affecting patients’quality of life.An accurate diagnosis of the underlying cause of pain is crucial for effective treatment.Chronic venous insufficiency(CVI)is frequently overlooked by pain physicians.Moreover,many pain physicians lack sufficient knowledge about CVI.CVI is a common condition resulting from malfunctioning or damaged valves in lower limb veins.Symptoms of CVI,ranging from mild to severe,include pain,heaviness,fatigue,itching,swelling,skin color changes,and ulcers in the lower limbs.Recently,it has become more widely known that these symptoms can be attributed to CVI.Even slight or mild CVI can cause related symptoms.Pain physicians primarily consider neuromusculoskeletal disorders when assessing patients with leg pain,and often neglect the possibility of CVI.In clinical practice,when pain physicians encounter patients with unresolved leg pain,they must assess whether the patients exhibit symptoms of CVI and conduct tests to differ-entiate CVI from other potential causes.
文摘Background: Chronic venous insufficiency (CVI) describes a condition that affects the venous system of the lower extremities due to venous hypertension (VH. The prevalence is between 5% - 30%. CVI is associated with older age, smoking, lower extremity trauma, presence of an arteriovenous shunt, and elevated estrogen levels. All patients should be initially treated with conservative management. Venoactive drugs like calcium dobesilate are useful. Objectives: The primary objective compared the clinical improvement in patients with CVI, grades 0 - 3 of the CEAP classification of chronic venous disease, produced by two formulations of calcium dobesilate: calcium dobesilate LP 1 g OD vs calcium dobesilate 500 mg BID, immediate release. The secondary objective assessed the side effects of both formulations. Method: All patients took one tablet and one capsule at 7 am, and one capsule at 7 pm, for 8 weeks. One group received dobesilate 1 g OD and the other group received dobesilate 500 md BID. They were evaluated after 15, 30 and 60 days of treatment, using the symptom evaluation scale. Results: In both groups, there was a significant decrease in the symptom score after 15 days. Four patients in the Dobesilate OD group: had adverse effects, which did not require suspension of treatment. In the BID dobesilate group, there was one therapeutic failure, and one case of gastric discomfort. Conclusions: Prolonged-release Calcium dobesilate 1 g OD is as effective as calcium dobesilate 500 mg BID for the treatment of patients with chronic venous insufficiency.

文摘The incidence of premature ovarian insufficiency(POI)is increasing worldwide,particularly among younger women,posing a significant challenge to fertility.In addition to menopausal symptoms,POI leads to several complications that profoundly affect female reproductive function and overall health.Unfortunately,current clinical treatment strategies for this condition are limited and often yield unsatisfactory outcomes.These approaches typically involve hormone repla-cement therapy combined with psychological support.Recently,mesenchymal stem cell(MSC)therapies for POI have garnered considerable attention in global research.MSCs can restore ovarian reproductive and endocrine functions through diverse mechanisms,including controlling differentiation,promoting angiogenesis,regulating ovarian fibrosis,inhibiting apoptosis,enhancing autocrine and paracrine effects,suppressing inflammation,modulating the immune system,and genetic regulation.This editorial offers a succinct summary of the application of MSC therapy in the context of POI,providing evidence for groundbreaking medical approaches that have potential to enhance reproductive health and overall well-being for women.
文摘BACKGROUND Premature ovarian insufficiency(POI)is a condition that causes secondary amenorrhea owing to ovarian hypofunction at an early stage.Early follicular depletion results in intractable infertility,thereby considerably reducing the quality of life of females.Given the continuum in weakened ovarian function,progressing from incipient ovarian failure(IOF)to transitional ovarian failure and further to POI,it is necessary to develop biomarkers for predicting POI.The oxidative stress states in IOF and POI were comprehensively evaluated via oxidative stress[diacron-reactive oxygen metabolites(d-ROMs)]test and anti-oxidant capacity[biological antioxidant potential(BAP)].METHODS Females presenting with secondary amenorrhea over 4 mo and a follicle stimulating hormone level of>40 mIU/mL were categorized into the POI group.Females presenting with a normal menstrual cycle and a follicle stimulating hormone level of>10.2 mIU/mL were categorized into the IOF group.Healthy females without ovarian hypofunction were categorized into the control group.Among females aged<40 years who visited our hospital from January 2021 to June 2022,we recruited 11 patients into both POI and IOF groups.For the potential antioxidant capacity,the relative oxidative stress index(BAP/d-ROMs×100)was calculated,and the oxidative stress defense system was comprehensively evaluated.RESULTS d-ROMs were significantly higher in the POI and IOF groups than in the control group,(478.2±58.7 U.CARR,434.5±60.6 U.CARR,and 341.1±35.1 U.CARR,respectively)(U.CARR is equivalent to 0.08 mg/dL of hydrogen peroxide).However,no significant difference was found between the POI and IOF groups.Regarding BAP,no significant difference was found between the control,IOF,and POI groups(2078.5±157.4μmol/L,2116.2±240.2μmol/L,and 2029.0±186.4μmol/L,respectively).The oxidative stress index was significantly higher in the POI and IOF groups than in the control group(23.7±3.3,20.7±3.6,and 16.5±2.1,respectively).However,no significant difference was found between the POI and IOF groups.CONCLUSION High levels of oxidative stress suggest that evaluating the oxidative stress state may be a useful indicator for the early detection of POI.
文摘Background: Cervical insufficiency is one of the major causes of preterm birth among pregnant women that leads to severe mortality and morbidity issues among newborns. Prophylactic cervical cerclage is a surgical procedure performed between 11 and 14 weeks of gestation upon diagnosis of cervix insufficiency among pregnant women. Aims & Objectives: In this study, we aimed to evaluate the effectiveness of prophylactic cervical cerclage in comparison to other interventions to treat cervical insufficiency among pregnant women using a meta-analysis approach. Methods: We searched the three databases (Coachrane Library, PubMed, and MEDLINE) that were used for articles related to research aims by using MeSH keywords. The timeline of research was set from January 2015 to January 2024. The methodological quality assessment of included studies was performed by the Risk of Bias in Non-randomized Studies—of Interventions (ROBINS-I). A recent meta-analysis was conducted by using Review Manager 5.4.0 software. Results: About 441 research articles were extracted from three electronic databases and only 125 articles were assessed for eligibility criteria. Finally, 8 studies were included in the analysis for a recent meta-analysis. Six out of eight included retrospective or pilot studies were graded as having a moderate risk of bias, and two studies had low risk on the basis of owning bias. About 1008 pregnant women with cervical insufficiency were analyzed in a recent meta-analysis. By pooled analysis, it was evaluated that significant difference found in prolongation of delivery weeks (Mean difference = 1.05;Cl: 0.81 to 1.29: p > 0.00001), number of deliveries > 37 weeks (OR = 0.59;Cl: 0.19 to 1.84: p > 0.006), and preterm birth (OR = 0.73;Cl: 0.42 to 1.28: p > 0.50) among pregnant women receiving prophylactic cervical cerclage as compared to other treatment strategies. Conclusion: Recent meta-analysis suggested the prophylactic cervical cerclage reduces the rates of preterm birth, abortion rates, number of deliveries > 37 weeks, and other complications as compared to the other cervical cerclage types and conservative treatments.
文摘Background: Isolated tricuspid valve disease remains a controversial indication for surgical intervention. Many patients referred for surgery already have a poor clinical condition and an advanced New York Heart Association functional class. There is no consensus on the optimal surgical technique for this condition, including on whether to perform the procedure on a beating or an arrested heart and whether to perform valve repair or replacement. Methods: We analyzed four case series between 2015 and 2022 in which patients with secondary tricuspid regurgitation (TR) underwent valve repair on a beating heart and right atrial plication for a dilated right atrium. The TRI-SCORE was calculated for each patient. Results: All patients experienced a favorable postoperative course with significant improvements in heart failure symptoms. TR was markedly reduced;however, in one patient with concomitant mitral regurgitation (MR) and a high TRI-SCORE, MR worsened postoperatively. This patient later died from unknown causes due to multiple comorbidities in the late phase. Conclusions: Tricuspid valve repair on a beating heart was effective for improving the cardiac function, and the TRI-SCORE proved useful as a preoperative risk assessment tool. The underlying mechanism by which TR exacerbates MR requires further investigation.

文摘Previous studies have shown that reduced sleep duration,sleep fragmentation,and decreased sleep quality in patients with Alzheimer's disease are related to dysfunction in orexin signaling.At the same time,blood-brain barrier disruption is considered an early biomarker of Alzheimer's disease.However,currently no report has examined how changes in orexin signaling relate to changes in the blood-brain barrier of patients who have Alzheimer's disease with sleep insufficiency.This cross-sectional study included 50 patients with Alzheimer's disease who received treatment in 2019 at Beijing Tiantan Hospital.Patients were divided into two groups:those with insufficient sleep(sleep duration≤6 hours,n=19,age 61.58±8.54 years,10 men)and those with normal sleep durations(sleep duration>6 hours,n=31,age 63.19±10.09 years,18 men).Demographic variables were collected to evaluate cognitive function,neuropsychiatric symptoms,and activities of daily living.The levels of orexin,its receptor proteins,and several blood-brain barrier factors were measured in cerebrospinal fluid.Sleep insufficiency was associated with impaired overall cognitive function that spanned multiple cognitive domains.Furthermore,levels of orexin and its receptors were upregulated in the cerebrospinal fluid,and the blood–brain barrier was destroyed.Both these events precipitated each other and accelerated the progression of Alzheimer's disease.These findings describe the clinical characteristics and potential mechanism underlying Alzheimer's disease accompanied by sleep deprivation.Inhibiting the upregulation of elements within the orexin system or preventing the breakdown of the blood-brain barrier could thus be targets for treating Alzheimer's disease.
文摘Antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE) are frequently discussed together and considered two closely related diseases.APS involves multiple organ systems,but APS-related endocrine manifestations are rare.^([1])Among them,adrenal insufficiency (AI) is the first endocrine manifestation of APS.The prompt diagnosis of AI is critical,as this disorder has high morbidity and mortality if left untreated.Here,we report a rare case of acute AI caused by APS secondary to SLE.CASEIn August 2022,a 39-year-old woman without a significant family history of medical diseases presented to our emergency department (ED) for low back pain,nausea,anorexia,fatigue,hypoglycemia,and hypotension.One month prior,she had fatigue,loss of appetite,low back pain,cough with sputum.
文摘Background: The suppression of the hypothalamic-pituitary-adrenal axis by cortisol-secreting adrenocortical tumors is well recognized and requires peri- and postoperative hydrocortisone substitution. Case Presentation: A 48-year-old female patient with hypertension and progressive weight gain, the clinical signs of hypercorticism motivated a hormonal workup revealing an independent ACTH Cushing’s syndrome: with urinary free cortisol (UFC) at 649 nmol/24h (4× normal), adrenocorticotropin hormone (ACTH) at 1.5 ng/l. The rest of the hormonal workup was not performed due to a lack of financial means. An Adrenal CT scan showed a 4 cm right adrenal adenoma. The patient underwent a right adrenalectomy with an adrenal adenoma on pathological examination. The contralateral side was normal. The patient was treated with hydrocortisone 30 mg/d for 6 weeks then 15 mg/d, during the monitoring we noted a persistence of the adrenal insufficiency for now 4 years. Basal cortisol levels during follow-up were very low (<3 μg/dl) ruling out the need for synacthen stimulation tests. Conclusion: Adrenal cortisol tumors are recognized by suppression, the duration of hypothalamic-pituitary-adrenal axis suppression is variable from 11 to 60 months depending on the series, which depends on the duration, severity of hypercortisolism, tumor size and other unknown factors. A longer follow-up of these patients is necessary to look for recovery of the contralateral adrenal gland.

文摘AIM:To observe the surgical effects of slanted bilateral lateral recession(S-BLR)versus conventional bilateral lateral recession(C-BLR)in convergence insufficiency intermittent exotropia(CI-IXT).METHODS:Using a randomized,double-blind,prospective design,22 patients with CI-IXT who were admitted to Renmin Hospital of Wuhan University from July 2019 to December 2020 were included.Patients were randomly divided into either S-BLR or C-BLR group for their subsequent strabismus surgery.All patients were followed up for 12mo.Near deviation,distant deviation,and neardistance difference(NDD)were measured in all patients.RESULTS:Twelve months after surgery,NDD improvement was 10(8,13)prismatic degrees(PD)in S-BLR group and 3(1,6)PD in C-BLR group(P=0.011).The near deviation of S-BLR group was 0(-2,2)PD,while that of C-BLR group was-4(-6,-3)PD(P=0.005).Before and after surgery,the difference in the distant deviation between the two groups was not statistically significant.There was no statistically significant difference in near stereopsis between the two groups(P=0.380)at 12mo.The success rate at 12mo after operation was 90.91%and 72.73%in the two groups(P=0.280).CONCLUSION:CI-IXT patients treated with S-BLR have better surgical outcomes than those treated with C-BLR,which indicates S-BLR is a safe and effective operation pattern.
文摘BACKGROUND Premature ovarian insufficiency(POI)is characterized by an early decline in ovarian function,inducing secondary amenorrhea.While the cause of POI has not yet been identified,the function of mitochondria in the ovaries and the cytotoxicity associated with reactive oxygen species(ROS)have been implicated in follicle pool depletion and a decline in follicle quality.Recently developed tests have enabled easy measurement of diacron-reactive oxygen metabolites(d-ROMs)and biological antioxidant potential(BAP).The combination of these two tests is used to comprehensively assess oxidative stress in the blood.AIM To comprehensively assess the oxidative stress of d-ROMs and BAP in POI.METHODS Participants were classified into two groups:A POI group of 11 women aged<40 years examined between January 2021 and June 2022 with a history of secondary amenorrhea for at least 4 mo in our hospital and an FSH value of≥40 mIU/mL;and a control group of healthy women of the same age with normal ovarian function in our hospital.Plasma d-ROMs and BAP were measured in both these groups underwent.Differences between groups were assessed using the t-test.RESULTS The mean age and mean body mass index(BMI)were 35.8±3.0 years and 20.1±1.9 kg/m2 in the control group and 35.8±2.7 years and 19.4±2.5 kg/m2 in the POI group,respectively.The mean gravidity and parity in control and POI groups were 0.6±0.7 and 0.4±0.5 and 0.6±0.9 and 0.3±0.5,respectively.The two groups did not differ significantly in terms of mean age,BMI,gravidity,or parity.The d-ROMs level was significantly higher in the POI group than in the control group(478.2±58.7 vs 341.1±35.1 U.CARR;P<0.001);however,the BAP level did not significantly differ between the two groups(2078.5±157.4 vs 2029.0±186.4μmol/L).The oxidase stress index(d-ROMs/BAP×100)was significantly higher in the POI group than in the control group(23.7±3.3 vs 16.5±2.1;P<0.001).CONCLUSION Oxidative stress was significantly greater in the POI group than in the control group,suggesting oxidative stress as a factor that can serve as a POI biomarker.
文摘BACKGROUND Tetralogy of Fallot(TOF)is one of the most common congenital heart defects,and surgery is the primary treatment.There are no precise guidelines on the treatment protocol for tricuspid regurgitation(TR)as a common complication of TOF repair.The timing for treatment in patients presenting with valve regurgitation after TOF repair is often difficult to determine.Here,we report the first case of sequential treatment of pulmonary and TR using interventional therapy.CASE SUMMARY We present the case of a 52-year-old female patient,who had a history of TOF repair at a young age.A few years later,the patient presented with pulmonary and tricuspid regurgitation.The symptoms persisted and TR worsened following percutaneous pulmonary valve implantation.Preoperative testing revealed that the patient’s disease had advanced to an intermediate to advanced stage and that her general health was precarious.Because open-heart surgery was not an option for the patient,transcatheter tricuspid valve replacement was suggested.This procedure was successful,and the patient recovered fully without any adverse effects.This case report may serve as a useful resource for planning future treatments.CONCLUSION Treatment of both valves should be considered in patients with tricuspid and pulmonary regurgitations following TOF repair.The interventional strategy could be an alternative for patients with poor general health.

文摘[Objectives]To observe the protective effects of Mongolian medicine Borantunggal on rats with chronic renal insufficiency.[Methods]Male Wister rats were gavaged with 50 mg/kg/d adenine for 12 consecutive weeks,and were intervened with positive control drug Niaoduqing and three groups of different doses of Mongolian medicine Borantunggal.The rats general state,such as body posture,hair color,activity status,renal function,thyroid gland,adrenal gland,and gonadal hormone levels,expression levels of inflammatory mediators,α-smooth muscle actin(α-SMA)and nuclear factor-κB(P65)in renal tissue,and histopathological changes of rat kidney were observed before and after treatment.[Results]The recovery of the general state of rats with chronic renal insufficiency in the low dose group after intervention with Mongolian medicine Borantunggal was the most obvious.Compared with the model group,the level of CRE in the low dose Mongolian medicine group decreased,and the difference was statistically significant(P<0.05).Compared with the normal group,the 24-h urinary protein in the low dose Mongolian medicine group had a declining trend,but the difference was not statistically significant(P>0.05).The urea level in low,medium and high dose Mongolian medicine groups showed a declining trend,and the effect of low dose Mongolian medicine was better.Compared with the model group,the feed intake of the low dose Mongolian medicine group had an increasing trend,while P and TCHO also had a declining trend.Compared with the model group,the levels of LH and COR in the low,medium and high dose Mongolian medicine groups decreased significantly,and the difference was statistically significant(P<0.05).The levels of T,T3 and T4 were significantly increased,the difference was statistically significant(P<0.05),and the effect of low dose Mongolian medicine was better.Compared with the model group,the levels of IL-6,TNF-αand HIF-1 in the low,medium and high dose Mongolian medicine groups were significantly reduced,and the difference was statistically significant(P<0.05).The levels of TGF-β1 and Ang II in the low dose Mongolian medicine group were significantly reduced,and the difference was statistically significant(P<0.05).The level of TGF-β1 in the medium and high dose Mongolian medicine groups decreased,and the difference was statistically significant(P<0.05).The expression of NF-κB P65 andα-SMA proteins in the low dose Mongolian medicine group showed a declining trend,which was better than Niaoduqing.[Conclusions]Mongolian medicine Borantunggal has significant protective and preventive effects on rats with adenine-induced chronic renal insufficiency.In particular,the dose of 0.31 kg/d had the most significant protective effect.Its action mechanism may be related to regulating hormone levels in the body,improving renal function,reducing renal inflammatory response,reducing the"three highs"in the kidney,and inhibiting renal tubular epithelial cell-to-mesenchymal transition and deposition of extracellular matrix(ECM).
文摘BACKGROUND As left bundle branch pacing(LBBP)is more like physiological pacing,LBBP has emerged as a novel pacing strategy that uses the native conduction system to improve ventricular synchronization with stable pacing parameters.LBBP has been revealed associated with a significantly reduced risk of new-onset atrial fibrillation and heart failure compared with conventional permanent pacemaker implantation.CASE SUMMARY A 64-year-old man was admitted with a 24-h history of chest distress and shortness of breath,which continued unabated.The patient had no symptoms of chest pain,dizziness,syncope,nausea nor vomiting.There were no abnormalities found in routine examinations after admission.Twelve-lead electrocardiogram presented a result of 2:1 atrioventricular block.Coronary angiography was performed the next day and no abnormality was found.Finally,the patient agreed to received LBBP and signed the informed consent.During the process of withdrawing the Medtronic Model 3830 lead into sheath,we found the lead helix was wrapped around the chordae tendineae of the septal valve of tricuspid.Attempts to rotate the 3830 lead failed to release the lead helix from the chordae tendineae,and ultimately we used radiofrequency ablation to ablate the wrapped chordae tendineae.CONCLUSION Radiofrequency ablation effectively solved this problem without complications.It is an effective and reliable method to resolve lead winding chordae.
文摘Objective: To investigate the mid-and long-term clinical effects of tricuspid valvuloplasty with the implantation of an artificial plastic ring.Methods: Data of 677 patients who had functional tricuspid regurgitation and left cardiac valve disease and underwent tricuspid valvuloplasty and left cardiac valve surgery were retrospectively.Among these patients, 353 underwent simple suture annuloplasty(group A) while the rest 324 patients underwent artificial plastic ring annuloplasty(group B).The two-year and more-than-two-year clinical and ultrasonocardiograph(UCG) follow-up data of the two groups were obtained and compared.Results: A total of 600 patients(88.6%) completed the long-term follow-up(more than two years).The two-year follow-up showed no significant difference in the incidence of mild tricuspid regurgitation between the two groups(82.2% vs.92.7%, P=0.37).However, there were significantly more cases that developed into moderate to severe tricuspid regurgitation in group A than in group B(17.8% vs.7.3%, P=0.031).The long-term follow-up revealed that the recurrence rate of tricuspid regurgitation in group B was significantly lower than that in group A(11.0% vs.25.0%, P=0.029), and the ratio of cases developing into moderate to severe tricuspid regurgitation in group A was significantly higher than that in group B(28.9% vs.9.9%, P=0.007).The comparison between the two intra-group time segments showed that the development of tricuspid regurgitation in group A was significantly increased(28.9% vs.17.8%, P=0.022), but in group B it was relatively stable(9.9% vs.7.3%, P=0.52).Conclusions: Artificial ring annuloplasty is associated with significantly less tricuspid regurgitation than simple suture annuloplasty.

文摘Pancreatic exocrine insufficiency is an important cause of maldigestion and a major complication in chronic pancreatitis.Normal digestion requires adequate stimulation of pancreatic secretion,sufficient production of digestive enzymes by pancreatic acinar cells,a pancreatic duct system without significant outflow obstruction and adequate mixing of the pancreatic juice with ingested food.Failure in any of these steps may result in pancreatic exocrine insufficiency,which leads to steatorrhea,weight loss and malnutrition-related complications,such as osteoporosis.Methods evaluating digestion,such as fecal fat quantification and the13C-mixed triglycerides test,are the most accurate tests for pancreatic exocrine insufficiency,but the probability of the diagnosis can also be estimated based on symptoms,signs of malnutrition in blood tests,fecal elastase 1 levels and signs of morphologically severe chronic pancreatitis on imaging.Treatment for pancreatic exocrine insufficiency includes support to stop smoking and alcohol consumption,dietary consultation,enzyme replacement therapy and a structured follow-up of nutritional status and the effect of treatment.Pancreatic enzyme replacement therapy is administered in the form of enteric-coated minimicro-spheres during meals.The dose should be in proportion to the fat content of the meal,usually 40-50000 lipase units per main meal,and half the dose is required for a snack.In cases that do not respond to initial treatment,the doses can be doubled,and proton inhibitors can be added to the treatment.This review focuses on current concepts of the diagnosis and treatment of pancreatic exocrine insufficiency.
