Objective:To compare transvaginal ultrasonography and hysteroscopy in diagnosis of intrauterine adhesions.Methods: One hundred and one cases of infertile women were treated by transvaginal ultrasound and hysteroscopy.Results: One hundred and one cases of infertility by hysteroscopy diagnosis of 87 cases of intrauterine adhesions, transvaginal ultrasound 68 cases of intrauterine adhesions, 78.16% sensitivity, sensitivity and different degree of intrauterine adhesions without significant difference. The diagnosis coincidence rate of intrauterine adhesions was consistent with transvaginal ultrasonography and hysteroscopy.Conclusion: In the clinical diagnosis and treatment of intrauterine adhesions, transvaginal sonography has the value of irreplaceable hysteroscopy. Vaginal ultrasonography can be used as the first choice for intrauterine adhesions.

Objective To characterize the clinical features and outcome of massive lower gastrointestinal hemorrhage in patients with Crohn's disease.Methods The clinical data form 13 patients Who identified as Crohn's disease accompanied by massive lower gastrointestinal hemorrhage between 1998 and 2007 were retrospectively analyzed.Results The ratio of men to women was 3.3 : 1.Bleeding was the first symptom of disease in foor patients.The lesion was involved in small howel in 10 cases.The origin of bleeding was identified in 8 cases.Four patients received surgical operation and none of them died,while 9 patients received medical treatment and 3 of them died.Totally 10 patients were followed up for 6 to 94 months.Eight patients had recurrent massive hemorrhage,and two of them subsequently required surgery.One patient died after surgery.All patients who had recurrent massive bleeding and still survival were characterized by recurrent bleeding as only or major clinical feature,and they were all with small bowel involvement.Conclusions Diagnostic and therapeutic approach of massive lower gastrointestinal hemorrhage in Crohn's disease is very challenging.It is possible that there exists a particular phenotype of Crohn's disease that presents a tendency of bleeding recurrence,whose bleeding probably related to small bowel lesions.

Objective To investigate circulating betatrophin levels in non-alcoholic fatty liver disease patients (NAFLD). To explore its association with various metabolic parameters in Chinese subjects. Methods From August 2014 to April 2015 , 58 patients with NAFLD and 41 non-NAFLD control subjects with age and sex matched were enrolled in the Department of Endocrinology of Zhujiang Hospital. Results In NAFLD group, serum betatrophin concentrations significantly increased (781.96 vs. 431.89 pg/mL, P < 0.05) and associated only with HDL-cholesterol level. In normal group, betetrophin levels are associated with multiple metabolic parameters, such as fasting glucose, insulin, C peptide, HOMA-IR, QUICK index and HDL-C levels. Conclusions Serum betatrophin concentration significantly elevated in non-alcoholic fatty liver disease patients and was negatively correlated with HDL-C level (r = -0.479, P < 0.001).

The teacher training of medical colleges has become a pressing task force.Young doctors should systematically study the educational theory,make positive observation,conduct teaching rounds and share experience,use the Internet,read the literature and pay attention to academic practice to improve clinical teaching ability.

Background Takayasu arteritis is a non specificity inflammation of aorta and its branch.The incidence of Takayasu arteritis is low and its ocular secondary disease is rare.The correct diagnosis of Takayasu arteritis is very important for its early treatment in clinic.Objective This study is to analyze the fundus findings and characteristic of fundus fluorescein angiography (FFA) of Takayasu retinopathy.Methods The FFA and clinical data of 12 patients (24 eyes) with Takayasu arteritis were retrospectively reviewed.Written informed consent was obtained from all the patients before and initiation of any study protocol.Results In 12 patients,chronic ischemic retinopathy was found in 15 eyes of 9 patients.The arm to retina circulation time(A RCT) prolonged to (19.20±2.95) s in 5 eyes,and the retinal circulation time (RCT) delayed to 10.62±6.15 s in 5 eyes.Peripapillary arteriovenous anastomosis was found in 2 eyes of 2 patients.Macular arch ring was incomplete in 6 eyes of 4 patients.Eight patients (14 eyes) had telangiectasis and microaneurysm,and 2 eyes of 2 patients presented neovascularization on the disc or elsewhere.In 12 patients,hypertensive retinopathy was found in 4 eyes of 3 patients,showing narrow retinal artery,arteriosclerosis,hemorrhage,cotton wool spots and hard exudates.Ten patients were diagnosed as Takayasu arteritis before FFA examination,and 2 patients were determinedly diagnosed after FFA was performed.Conclusion The main features of Takayasu retinopathy are hypertensive retinopathy and chronic ischemic retinopathy.It is important for ophthalmologist to correctly recognize the clinical features of TA.

[Objective] To investigate the change of liver histology, proliferation of BDEC, and expression of TGF-β in different stages of liver chelestusis. [Methods] ①Rat cholestatic livers were induced by common bile duct ligation (BDL) and separated into 3 groups, namely control group (DO), 7 days after BDL group (DT), and 18 days after BDL group (D18). ② Histological changes of livers in different groups were evaluated based on Knodell HAI score. ③ Real-time PCR was used to detect the expression of TGF-β in liver tissue and isolated BDEC in different groups. ④ Statistically analyzing the correlation between Knedell HAl score and the levels of TGF-β_1 mRNA. ⑤ In vitro study was performed to investigate the effect of TGF-β_1 on an immortalized mouse intrahepatic bililary epithelial cell line (mIBEC). [Results] (I) Knedell HAI score and the proliferation of intrahepatic bile ducts increased as the liver cholestasis aggravated. ② The levels of TGF-β_1, TGF-β_2, and TGF-β_3 mRNA were significantly up-regulated in liver tissues and BDEC as the liver cholestasis aggravated. ③ Positive correlation was found between Knedell fibrotic score and the levels of TGF-β_1 mRNA in liver tissues and BDEC(r=0.9376, P<0.05 and r=0.9682, P < 0.01). ④ In vitro study showed that TGF-β_1 inhibited the proliferation of mIBEC. [Conclusion] ① Liver injury, biliary proliferation, and the levels of TGF-β mRNA expression increased as liver cholestasis aggravated. ② The interaction of TGF-β_1 and BDEC plays an important role in the pathogenesis of BDL induced cholestatic liver disease. ④ Up-regulated expression of TGF-β_1 mRNA in the proliferated BDEC participates in the formation of BDL induced cholestatic liver fibrosis.

Objective To investigate the evaluation standard and proper time point of anti-tuberculosis trial for differential diagnosis between intestinal tuberculosis (ITB) and Crohn's disease (CD). Methods Clinical data and endoscopic changes of 28 patients with confirmed ITB and 11 with confirmed CD,who underwent anti-tuberculosis trail, were retrospectively analyzed. Results No significant difference could be found in clinical characteristics of ITB and CD patients on baseline, such as active pulmonary tuberculosis, strong positive skin test and anal fistula/perianal abscess. Clinical symptoms were relieved in both groups right after anti-tuberculosis treatment. After 3 months of treatment, the no-improvement rate in ITB group was 0, whereas that of CD group was 27.3% (P =0. 004). The disappearance rate plus improvement rate of ulcer in ITB group was 90. 9% (20/22) plus 9. 1% (2/22) and 100% ( 28/28 ) plus 0 at 3 and 6 months of treatment, respectively. The disappearance rate plus improvement rate of nodular lesion was 58. 8% (10/17) plus 41.2% (7/17) and 76. 5% (13/17) plus 23.5% (4/17), respectively. There was no obvious improvement of active ulcer or nodular transformation in CD group at any time point ( P ＜ 0. 01 ).Conclusion With deficiency of special index for differential diagnosis of ITB and CD, some cases hard to differentiate still have to accept anti-tuberculosis treatment. Three months of anti-tuberculosis treatment is a proper time point to evaluate the efficacy. Disappearance of active ulcer and nodular transformation, together with cure or obvious improvement in clinic are taken as effective for treatment trail.

Objective To inspect the efficacy and mucosa healing condition of infliximab with azathioprine combination therapy in Crohn's disease (CD) and its correlation with prognosis.Methods A total of 20 active CD patients who received infliximab and azathioprine combination therapy at The First Affiliated Hospital of Sun Yat-sen University were objects of this study.The clinical efficacy was evaluated at 10 weeks,30 weeks,54 weeks and 2 years respectively according to CD activity index.The efficacy was evaluated under endoscopy at 10 weeks,30 weeks,54 weeks and 2 years respectively according to mucosal response situation under endoscopy.The data were analyzed by analysis of variance or Fisher's exact test between two groups.The factor affecred mucosal healing was analyzed by Logistic regression analysis.Results The clinical remission rate of patients without steroid at week 10,30,54 and 2 year were 12/20,16/20,15/20 and 15/20 respectively.Mucosal healing rate at week 10,30 and 54 weeks were 8/20,12/20 and 10/20 respectively.Logistic regression analysis indicated that age was the only factor affected mucosal healing at 30 weeks (OR =0.774,95％ CI:0.630 to 0.950).There was significant differences in clinical remission between mucosa response patients and invalid under endoscopy at 30 weeks and 2 years without steroid (at 30 weeks:14/14 vs 2/6; at 2 years:14/14 vs 1/6; all P＜0.01).Infliximab were withdrawn in 4 of 16 patients who was in non-steroid clinical remission at 30 weeks,and the other 12 patients were continued with infliximab therapy.There was no significant difference in non-steroid clinical remission rate (4/4 vs 11/12) and mucosa healing rate (2/4 vs 7/12) between withdrawal and continue of infliximab therapy (all P＞0.05).Conclusions Infliximab with azathioprine combination therapy can effectively promote and maintain mucosa healing in CD.The mucosa response patients can maintain long time non-steroid clinical remission.

ObjectiveTo investigate the health status and incidence of alcohol abuse of Xinjiang community residents.MethodsThrough multi-stage random sampling,1992 community residents ( 15-65years old) were assessed using socio-demographic information questionnaire,alcohol use disorders identification test (AUDIT) and self-rated health measurement scale-prior test(SHRMS).Single factor analysis and rank sum test were used to identify the incidence of alcohol abuse,the distribution of different populations,and the self-rated health status of abusers.ResultsTotally 298 cases of alcohol abuse were identified,and accordingly,the prevalence rate of alcohol abuse for general population was 15.1％ ( male 26.4％,female 4.8％ ).Key factors for alcohol abuse included male,middle-aged,well-educated,at work,administrative work,high income levels and large number of household.The differences among groups were statistical significant.Presumably the workplace population was at high risk of alcohol abuse.Alcohol abusers were significantly worse than general population in self-rated health status(P ＜ 0.01 ),especially in mental health and social health.ConclusionThe incidence of alcohol abuse is relatively high in Xinjiang rcgion,and the problem need more attention.Further survey and early intervention work for highrisk group are advised to achieve the purpose of prevention and control.
