Objective To investigate prevalence of metabolic syndrome (MS) and its related factors in patients with maintaining hemodialysis (MHD). Methods A total of 162 cases on MHD in Beijing Chaoyang Hospital during June to December 2010, were enrolled in this study and divided into MS group and non-MS group according to the diagnostic criteria for MS set by the International Diabetes Federation. Anthropometric and blood biochemical characteristics of the two groups were compared with t-test and x2 test Risk factors for MS were explored with binary logistic regression analysis. Results Prevalence of MS was 40. 7% (66/162) . There was significant difference found in body mass index [(24. 2 ±3. 1) vs. (21. 6 ±2. 7) kg/m2], waistline circumference[(93 ±8) vs. (79 ±7)cm] , white blood cell count [(6. 8 ± 1. 5) × 109/L vs. (5. 6 ± 1. 4) × 109/L] , hypersensitive serum C-reactive protein [(7 ± 5)vs. (4 ±3) mg/L], high-density lipoprotein-cholesterol [(0. 99 ±0. 26)vs. (1.39 ±0.39) mmol/L], low-density lipoprotein-cholesterol [(2. 5 ± 0. 8) vs. ( 2. 1 ± 0. 7) mmol/L], triglyceride ( TG) [( 2. 1 ±1.1 )vs. (1.3±0.8) mmol/L], fasting blood glucose [(5.9±2. 7)vs. (4.8±1.3) mmol/L], serum level of iron [(16±7)vs. (13 ±5) μmol/L], uric acid [(429±114) vs. (388±88) (μmol/L], and carbon dioxide combining power (CO2CP) [(22 ±4)vs. (23 ±4) mmol/L]between MS group and non-MS group (All P < 0.05 ) . But there was no significant difference found in subjective global assessment of nutritional status (SGA) , thickness of skin fold of the triceps muscle (TSF) between the two groups (Both P > 0.05). Binary logistic regressive analysis revealed that serum level of iron (OR = 1.058,95% CI = 1.001 -1. 119), white blood cell count ( OR = 1. 786,95% CI = 1. 346 - 2.371) and hypersensitive serum C-reactive protein (OR = 1. 101,95% CI = 1.010 - 1.201 ) were independent risk factors for MS in MHD patients. Conclusions Morbidity of MS is high in patients with MHD, involved with inflammation process. Serum level of iron, white blood cell count and hypersensitive serum C-reactive protein are independent risk factors for MS in patients with MHD and no inevitable connection between MS and nutritional status in them is found.

Mother-to-child transmission (MTCT)is an important way of hepatitis B virus (HBV)transmission.Blocking the HBV MTCT has a great significance for the prevention and treatment of hepatitis B.This article reviews the current blocking strategies implemented in the antepar-tum,peripartum,and postpartum stages,and summarizes the controversies existing in the blocking strategies in different stages.The significance of HBV occult infection and germ cell transmission in the HBV MTCT is analyzed.The results indicate that the current strategies for the prevention of hepatitis B MTCT need further improvement.Attentions should be focused on HBV occult infection and germ cell transmission.

Objective To compare the clinical utility of s7 and s670 intracoronary sents in the management of patients with coronary artery disease. Methods The clinical follow-up outcomes of 68 patients after implantation of s7 (n=32; group Ⅰ) and s670 (n=36;group Ⅱ) intracoronary stents were retrospectively analysed. Results The successful procedure rates were 100% in group Ⅰ and 97.2% in groupⅡ. The follow-up period was six months for both groups. In group Ⅰ, there were no death, no re-infarction and no revascularization but 2 patients experienced reccurrence of angina ( 6.25%). In group Ⅱ, there were 1 death, 1 patient undergoing revascularization, 3 patients suffering from reccurrence of angina ( 13.8%). Conclusions Both s7 and s670 intracoronary stents appear to be safe and effective in the treatment of coronary lesions with favorable outcomes.

Objective To study the relationship between sex hormones and uric acid in elderly women with coronary heart disease. Methods One handred and fifteen post menopausal female patients were divided into two groups by angiographic results, CAD group (n=61)and control group(n=76).Their serum concentrations of sex hormones and uric acid and general characteristics were compared. Results Baseline clinical characteristics were similar between the two groups,except patients in the CAD group were more likely to have hypertention and diabetes mellitus than the control group .Serum concentrations of estradiol and progestin and androgen showed little difference between CAD and control group,meanwhile, serum uric acid was higher(345.6?96.5 vs 307.9?85.5, P

ObjectiveTo study the epidemiological characteristics of leprosy in China,2001-2010.MethodsData were collected from the database of the national system of leprosy surveillance.A descriptive and comparative analysis was performed.ResultsTotally,15 507 new leprosy cases were detected from 2001 to 2010 with an average case detection rate of 0.118 per 100 000 population.Among these cases,2.7% were children under 15 years,86.5% multibacillary,and 22.5% suffered from grade 2 disability.From 2001 to 2010,a total of 1506 relapse cases were detected,and relapse occurred after multi-drug therapy(MDT) in 464 of these cases.There were significant differences between low and high endemic areas in the proportion of children under 15 years,females,immigrant patients among newly detected patients as well as the proportion of cases of relapse after MDT among all the relapse cases.By the end of 2010,the registered leprosy cases were 6032 with a prevalence rate of 0.450 per 100 000 population,among whom 2886 were under MDT.ConclusionsThe leprosy case detection rate continued to decrease in China from 2001 to 2010 with an unequal distribution.The pocket areas were in Yunnan province,Guizhou province,Sichuan province,Guangdong province,Hunan province and Tibet Autonomous Region.It is warranted to enhance the control of leprosy and reduce the prevalence of disability due to leprosy.

Iatrogenic traumatic biliary stricture is one of the difficult points in the biliary surgery,and operation is the only definitive treatment. The operative opportunity,surgical procedure and techniques are important for the prognosis.From January 1998 to December 2011,173 patients with iatrogenic traumatic stricture were admitted to the Eastern Hepatobiliary Surgery Hospital. According to the Bismuth classification of traumatic biliary stricture,10 patients were in type Ⅰ,22 in type Ⅱ,87 in type Ⅲ,38 in type Ⅳ and 16 in type Ⅴ.Excision of the traumatic stricture with end-to-end anastomosis was performed on 19 patients.Of the 173 patients,154 were treated by Roux-en-Y duodenojejunostomy, and 8 of them received additional hemihepatectomy or partial hepatectomy.A total of 155patients were followed up,with a median time of 74 months,the total excellent and good rate was 94.8% ( 147/155 ).Surgery is the most effective therapy for iatrogenic traumatic biliary stricture. Optimal timing, reasonable surgical methods, strictly following the principle of biliary surgery and perfect operative skills are key points for a better prognosis.

AIM: To compare pharmacokinetics and relative bioavailability of telmisartan capsule (T) and telmisartan tablet(R). METHODS: 20 male healthy Chinese volunteers were enrolled in a randomized two-way crossover designs with a single-oral dose study(80 mg once per day for each preparation). The plasma telmisatan concentration was determined by HPLC- fluorescence detector. Plasma levels of telmisatan were followed up to 96 h. Area under the telmisartan concentration time curve was calculated by variance analysis and the bioequivalent was determined by two one-side t-test. RESULTS: A two-compartment model was adopted in telmisartan plasma concentration-time data analysis. The pharmacokinetic parameters of T and R in single-dose study including Cmax (μg·L-1), Tmax (h), T1/2β (h), MRT(h), AUC0-92(μg·h·L-1) were as following: 456±253 and 760±314, 1.61±0.71 and 1.08±0.36, 22.39±6.29 and 21.08±5.24, 27.02±6.23 and 24.27±5.79, 3454±1050 and 3635±1300, respectively. Statistically significant differences were observed between the parameter values of the two products in Cmax and Tmax; whereas there was no statistically significant difference between AUC0-∞μg·h·L-1 (3601±1095 and 3767±1399). The relative bioavailability for T was 97.28%±12.74%. CONCLUSION: The test telmisartan capsule is bioequivalent to the reference tablet.
