Objective To investigate the effect of stoma skin care powde combined with skin protective mem-brane in prevention and treatment of secondary eczema after anal fistula surgery. Methods Eighty-three patients after anal fistula operation were divided into test group and control group. On the basis of routine treatment,the pa-tients in test group were used stoma skin care powder combined with skin protective membrane to protect the peri-anal skin. While the patients in control group were treated routinely. The degree of pruritus,the onset time,the number of skin lesions,the area of eczema and the healing time of eczema were observed in two groups 4 d,14 d and 24 d post-operation. Results Patients in test group had lowerdegree of pruritus,later onset time after dressing, less skin lesions,samller area of eczemaand shorter healing time of eczema than patients in control group in the 3 time nodes (all P<0.05). Conclusion Stoma skin care powder combined with skin protective membrane could effec-tively isolatepostoperative wound secretions and anus polyrrhea,and have preventive and therapeutic effects on sec-ondary perianal eczema after anal fistula surgery.

Urinary excretions of transforming grow th factor-? 1 (TGF-? 1), laminin (LN) and type Ⅳ collagen were determined i n 182 type 2 diabetic patients. Urinary excretions of TGF-? 1, LN and type Ⅳ collagen were increased in type 2 diabetic patients, and these findings were fa irly well correlated with severity of diabetic nephropathy (DN). Urinary TGF-? 1 seems to be the early index of DN, urinary LN and type Ⅳ collagen appear to be the indices of DN severity.

AIM: To investigate the molecular mechanism of amylin in inducing apoptosis of human pancreatic islet ?-cells. METHODS: Human pancreatic islet cells were isolated and cultured. The cells were treated with amylin or amylin and aminoguanidine (AG group) for 24 h, respectively. Apoptosis of pancreatic islet ?-cells was studied by in situ TUNEL method combined with double staining for insulin and ELISA. The levels of insulin, NO 2 -/NO 3 - and glutathione (GSH), p53 mRNA and bcl-2 mRNA were also detected. RESULTS: (1) The enrichment factor and the apoptosis rate of pancreatic islet ?-cells in amylin group were markedly higher than that in control group and AG group ( P

AIM: To investigate the effect of losartan on the mRNA expression of type 2 angiotensin II receptor and cytokines in diabetic rat kidney.METHODS: SD rats were randomly divided by following groups: control rats(group C),diabetic rats(group D) and diabetic rats treated with losartan (30(mg?kg~(-1)?d~(-1)),by gavage,group DT).At the end of 8-weeks study,mRNA expressions of the type 2 angiotensin II receptor(AT_2),transforming growth factor-?_1(TGF-?_1),platelet-derived growth factor-B(PDGF-B),tumor necrosis factor-?(TNF-?) and collagen Ⅳ in rats renal cortex were measured by RT-PCR,respectively.In addition,angiotensin Ⅱ level in renal cortex was determined by the radioimmunoassay.RESULTS: In group D,urine protein excretion(P

Objective To compare the safety and efficacy of insulin degludec (IDeg) with those of insulin glargine (IGlar) in insulin-naive subjects with type 2 diabetes (T2DM).Methods This was a 26-week,randomized,open-label,parallel-group,treat-to-target trial in 560 Chinese subjects with T2DM (men/women:274/263,mean age 56 years,mean diabetes duration 7 years) inadequately controlled on oral antidiabetic drugs (OADs).Subjects were randomized 2:1 to once-daily IDeg (373 subjects) or IGlar(187 subjects),both in combination with metformin.The primary endpoint was changes from baseline in glycosylated hemoglobin(HbA1c) after 26 weeks.Results Mean HbA1c decreased from 8.2％ in both groups to 6.9％ in IDeg and 7.0％ in IGlar,respectively.Estimated treatment difference (ETD) of IDegIGlar in change from baseline was-0.10％ points (95％ CI-0.25-0.05).The proportion of subjects achieving HbA1c ＜ 7.0％ was 56.3％ and 49.7％ with IDeg and IGlar,respectively [estimated odds ratio of IDeg/IGlar:1.26 (95 ％ CI 0.88-1.82)].Numerically lower rateof overall confirmed hypoglycaemia and statistically significantly lower nocturnal confirmed hypoglycemia were associated with IDeg compared with IGlar,respectively [estimated rateratio of IDeg/IGlar 0.69 (95％ CI 0.46-1.03),and 0.43 (95％ CI 0.19-0.97)].No differences in other safety parameters were found between the two groups.Conclusions IDeg was non-inferior to IGlar in terms of glycaemic control,and was associated with a statistically significantly lower rate of nocturnal confirmed hypoglycaemia.IDeg is considered to be suitable for initiating insulin therapy in Chinese T2DM patients on OADs requiring intensified treatment.Clinical trail registration Clinicaltrials.gov,NCT01849289.

AIM:To investigate the antagonism mechanism of benazepril on renal fibrosis of unilateral uretreal obstructire (UUO).METHODS:Fiftyfour Sprague-Dawley (SD) rats were randomly divided into three groups:sham operation group,model group,benazepril group.All the other groups were treated with surgery method of unilateral ureteral ligation to establish a rat model of renal fibrosis except the sham operation group.The pathological changes were observed by Masson staining;the positive staining expression of TGF-β1,Col-Ⅳ,Wnt1,Wnt4 in frozen sections were observed by immunofluorescence staining;the expressions TGF-β1,Col-Ⅳ,Wnt1 and Wnt4 mRNA in renal tissues were detected by real time fluorescence quantitative PCR.RESULTS:Masson staining results:compared with the sham group,the parts of blue dye collagen fiber and the degree of renal fibrosis increased significantly in all modeled groups;compared with the model group,the parts of blue dye collagen fiber and the degree of renal fibrosis decreased significantly in benazepril group.Immunofluorescence and PCR results:compared with the model group,the positive expression of Wnt1,Wnt4,TGF-β1,Col-Ⅳ and mRNA in the benazepril group decreased significantly.CONCLUSION:Benazepril can improve renal fibrosis by inhibiting the expression of TGF-β1,Col-Ⅴ,Wnt1,Wnt4 and ameliorating the level of renal fibrosis.

Objective To discuss the genotype and phenotype features of 187 patients with spinocerebellar ataxia type 3 (SCA3) and analyze their genotype-phenotype relationship.Methods A total of 187 patients genetically diagnosed as having SCA3 from 160 families were enrolled from our hospital from 2005 to 2015.Detailed medical histories were collected.SPSS 22.0 was conducted to statistically analyze the genotypes and pathogenic CAG expansions of A TXN3 gene in the patients.Results One hundred males and 87 females suffered SCA3.Mean age at onset was 35.43±11.17 years.The ranges of pathogenic CAG expansion were 65-86 repeats,with mean pathogenic CAG expansion of 74.11±3.56 repeats.A negative correlation was found between number of CAG repeats and age of onset (r=-0.815,P=0.000).Frequencies of the patients with tendon hyporeflexia were 28.9％ and 6.0％,respectively,in the smaller pathogenic CAG expansion group (≤74) and larger pathogenic CAG expansion group (＞74),with significant difference (P＜0.05).Frequencies of patients with rigidity were 27.8％ and 49.4％,respectively,in the smaller pathogenic CAG expansion group and larger pathogenic CAG expansion group,with significant difference (P＜0.05).Conclusions SCA3 is neurodegenerative disorder with high clinical and genetical heterogeneity.There are distinct correlations between number of pathogenic CAG expansion and age of onset,frequency ofhyporeflexia and rigidity.

Background: and PurposeHyperekplexia (HPX), a rare neurogenetic disorder, is classically characterized by neonatal hypertonia, exaggerated startle response provoked by the sudden external stimuli and followed by a shortly general stiffness. Glycine receptor alpha 1 (GLRA1) is the major pathogenic gene of the disease. We described the clinical manifestations of genetically confirmed HPX patients and made a literature review of GLRA1-related HPX to improve the early recognition and prompt the management of the disorder. Methods: Extensive clinical evaluations were analyzed in 4 Chinese HPX patients from two unrelated families. Next generation sequencing was conducted in the probands. Sanger sequence and segregation analysis were applied to confirm the findings. Results: All four patients including 3 males and 1 female presented with excessive startle reflex, a cautious gait and recurrent falls. Moreover, startle episodes were dramatically improved with the treatment of clonazepam in all cases. Exome sequencing revealed 2 homozygous GLRA1 mutations in the patients. The mutation c.1286T>A p.I429N has been previously reported, while c.754delC p.L252* is novel. Conclusions HPX is a treatable disease, and clonazepam is the drug of choice. By studying and reviewing the disorder, we summarized the phenotype, expanded the genotype spectrum, and discussed the possible pathogenic mechanisms to enhance the understanding and recognition of the disease. Early awareness of the disease is crucial to the prompt and proper administration, as well as the genetic counseling.

Objective: To investigate the efficacy and safety of percutaneous lauromacrogol injection (PLI) in treatment of cystic or predominantly cystic thyroid nodules. Methods: A total of 114 cystic thyroid nodules and 61 predominantly cystic thyroid nodules with pain or uncomfort or aesthetic complaints were offered PLI. Therapeutic success rates and side effects were evaluated. From October 2012 to December 2015,114 patients with cystic thyroid nodules and 61 with predominantly cystic thyroid nodules with pain or uncomfortable or aesthetic complaints at the outpatient clinic of the First Affiliated Hospital of Wenzhou Medical University were offered percutaneous lauromacrogol sclerotherapy. Cytological results were benign. This study was a prospective trial. Ultrasonography sound examination was performed in all patients before treatment. The baseline data of all the patients and the data of the patients examined at the follow-up of 1, 3, 6 and 12 months were analyzed. Therapeutic success rate (nodule volume reduction >50%) and safety were observed. The data of nodule volume reduction ratio and the function of thyroid were normal distribution and analyzed by Mann-Whitney test and t test. The data of nodule volume, symptoms score and cosmetic score were skewed distribution, which were indicated with median and analyzed by nonparamentic test. Results: The mean volume of the cystic thyroid nodules was reduced from 12.5 cm³ before PLI to 0.2 cm³ at 12 months after PLI (χ²=266.175, P<0.001), with a therapeutic success rate of 100%, and the mean volume of the predominantly cystic thyroid nodules was reduced from 10.5 cm³ before PLI to 2.0 cm³ at 12 months after PLI (χ²=203.122, P<0.001) with a therapeutic success rate of 93.4%(57/61). Pressure symptom score and cosmetic grade were significantly improved at 12 months after PLI in patients with cystic or predominantly cystic thyroid nodules. Pressure symptom score and cosmetic grade in patients with cystic thyroid nodules were Z=-6.126 and Z=-13.735, respectively; pressure symptom score and cosmetic grade in patients with predominantly cystic thyroid nodules were Z=-3.126 and Z=-7.212, respectively (all P<0.001) . There no significant difference in the thyroid functions before and after PLI in two groups of patients (all P>0.05) . The side effects of PLI were mild. Conclusion PLI is a safe and effective alternative to treat benign cystic or predominantly cystic thyroid nodules.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.
