Objective To understand the prevalence and Influencing factors of Metabolic Syndrome(MS) of 40～74 year-old non-diabetes population in Minhang District.Methods A population-based sample(diabetes screening of Minhang District in 2007) of 3 947 individuals aged 40～74 years was investigated by cluster random sampling.They completed a questionnaire and underwent triglyceride,high density lipoprotein measured cholesterol and an oral glucose tolerance test.Results The standardized prevalence rate of MS,overweight,diabetes,impaired glucose regulation(IGR),hypertension,high triglyceride and low HDL were 15.67%,2.45%,5.60%,17.72%,16.47% and 2.00%.The male with MS,overweight or obese,diabetes and hypertension were higher than the female in terms of incidence.The prevalence of MS was increased with age,the highest rate at the ages of 50 years and above.There was no significant difference between male and female at the ages of 45 years and above.The incidence of MS in people with BMI or hypertension or abnormal blood glucose or hige TG or low HDL-C was obviously higher than that of normal population.The OR value were 15.71,28.21,10.09,30.31 and 3.14 respectively.The prevalence of diabetes,coronary heart disease and stroke in people with MS was higher than that of people with out MS.The OR value were 10.09,9.94 and 2.40.Multiple factor analysis showed that the factors related to MS were male,the aged,family history of diabetes and having no physical activity.Conclusions MS and realated diseases are a serious threat to population of 40 years old and above in Minhang District.

Objective To assess the long-term survival and prognosfie factors in a series of patients with distal bile duet carcinoma. Methods A retrospective clinical analysis was made on 76 cases of distal bile duct cancer who were admitted into our hospital from January 1996 to December 2006. Clinicopathologic factors with possible prognostic significanees were selected and analyzed. Survival was calculated with the Kaplan-Meier method. A multivariate analysis of these individuals was performed using the Cox proportional Hazards Model. Results There were 46 males and 30 females. The age ranged from 21 to 88 years with a mean of 65.21 patients received palliative surgery including, bypass procedure, intraoperative biliary stenting, or percutaneous transhepatie biliary drainage. Radical resection was performed on 42 cases and the 1-, 3- and 5-yeur survival rates were 88.0%, 41.3% and 29.2% respectively. 38 cases died of liver metastasis or recurrence. In multivariate analysis, surgical procedure (P = 0.006) and liver metastasis (P = 0.008), but not sex, age, invasion of pancreas, invasion of duodenum, diameter or differentiation of tumor, were significant independent prognostic factors. Conclusions Radical resection is only curative treatment modality. Prevention on postoperative liver metastasis is essential for improving survival.

Objective To distinguish choriocarcinoma from gestational or non-gestational choriocarcinoma and also identify the causative pregnancy of gestational choriocarcinoma by the genetic origin through molecular genetic analysis. Methods Twelve patients with choriocarcinoma, who had experienced surgery prior to chemotherapy were enrolled in this study. All 12 cases were diagnosed pathologically as choriocarcinoma. Peripheral venous blood samples and formalin-fixed paraffin-embedded blocks of choriocarcinoma tissue microdissected from haematoxylin and eosin-stained sections of tissue by microdissection method were available from the patient and (or) her husband. DNA was then prepared from the couples' blood samples and choriocarcinoma tissue by using standard techniques. PCR amplification and fluorescent microsatellite genotyping were performed by using DNA from the couples and captured choriocarcinoma tissues. The genetic contributions to the choriocarcinoma tissue were determined by comparing the fragments of genes from the choriocarcinoma tissue to those from blood samples of the couples. Results The primary lesion was ovary in 7 cases, but only 4 of them had the maternal contribution, indicating a non-gestational origin; the other three were gestational choriocarcinoma. The primary lesion was uterus in 5 cases, which were all gestational choriocarcinoma confirmed by genetic analyses. The causative pregnancies of the 8 cases with gestational choriocarcinoma were identified as androgenetic complete hydatidiform mole (AnCHM) in six cases and normal pregnancies in two cases, respectively. Conclusion Microsatellite polymorphism analysis is a molecular approach for distinguishing the non-gestational choriocarcinoma from the gestational one, and also be used to identify the causative pregnancy of gestational choriocarcinoma.

Objectives To investigate the relationship between atherosclerotic acute myocardial infarction (AMI),acute cerebral infarction (ACI)and homocysteine (Hcy). Methods Three hundred and twenty consecutive patients with primary acute myocardial infarction (AMI)(group A)were admitted to the Department of Cardiology,310 patients with primary large artery atherosclerotic cerebral infarction (group B)were admitted to the Department of Neurology,and 327 healthy individuals without cardiovascular and cerebrovascular diseases (group C)at the Department of Physical Examination,Xuanwu Hospital, Capital Medical University were enrolled retrospectively from March 2010 to October 2011. The age and sex were matched in the 3 groups. All the clinical data of subjects were colleted in detail and then were compared and analyzed. Results (1)The Hcy levels (μmol/L)of group A,B,and C were 15. 10 (12. 43, 19.47),15. 80 (13. 10,20. 83),and 13. 20 (11. 00,16. 50;median [interquartile range]),respectively. There were significant differences among the 3 groups (P<0. 05). The incidences of hyperhomocysteinemia (HHcy)were 92. 8%(n=297),97. 1%(n=301),and 84. 7%(n=277)(P<0. 05). (2)Multivariate Logistic regression analysis showed that the independent risk factors for ACI were HHcy (OR 8. 97,95% CI 3. 01-26. 71),hypertension,diabetes,hyperlipidemia and blood ureanitrogen;the independent risk factors for AMI were HHcy (OR 4. 36,95% CI 1. 70-11. 21),hypertension,diabetes,hyperlipidemia,and total blood cholesterol. Conclusion HHcy is an independent factor for ACI and AMI,which have closer relationship with ACI. ACI and AMI have some common risk factors,but their degrees of action are different.

Objective To approach the efficiency and feasibility of preserving the fertility for patients with placental site trophoblastic tumor ( PSTT ).Methods Totally 2 086 cases of gestational trophoblastic neoplasm ( GTN) patients registered in Peking Union Medical College Hospital between 1998 and 2013.Fifty-seven of them were PSTT patients , 40 cases of which suffered hysterectomy , the rest 17 PSTT patients who preserved their fertility were analyzed retrospectively.The computerized database of clinical and pathological reports was reviewed in this cohort.Results The clinical manifestation of PSTT was not specific compared to other types of GTN.The average age of the 17 patients was 29.5 years old (range 22-39 years).The most common antecedent pregnancy was term birth (8 cases), the others were spontaneous abortion in 4 case, artificial abortion in 3 cases and molar pregnancy in 2 cases.The baseline serum β-hCG was slightly elevated and 12 patients (12/15) were less than 1 000 U/L.In this cohort, nine of the patients were in stage Ⅰ, while the other eight cases were in stage Ⅲ .The patients suffered conservative surgery, including dilation and curettage of uterus in 7 cases, open abdomen uterine lesion excision in 4 cases, laparoscopic uterine lesion excision in 3 cases, hysteroscopic uterine lesion excision in 1 case, and pulmonary lobectomy in 2 cases.Two of the patients didn′t received chemotherapy , while the other 15 cases suffered combination chemotherapy.Compared with 40 patients who suffered hysterectomy during the same interval , fertility preservation group did not result in poor outcomes or high risk of relapse rate.Six subsequent pregnancies happened after the therapy , two of them were during their second-trimester, while four patients had healthy babies by vaginal delivery in two and cesarean section in two .The scar of the uterus was fairly well during the cesarean sections.Conclusions Reservation of fertility therapy could be considered in highly-selected patients for young women who strongly desired to preserve their fertility and with localized lesion.Exactitude follow-up after therapy should be recommended.Contraception should also be recommended for at least one year after the chemotherapy.Vaginal delivery could be an option for the future pregnancies.

Objective To investigate the effects of different doses of alcohol on the synthesis of testosterone and the expression of androgen binding protein(ABP)mRNA in rat testis.Methods Forty male Wistar rats were randomly divided into 4 groups(10 rats each group)and received either distilled water(control group)or alcohol(alcohol-fed groups)for 5 months.Alcohol was administered by garage with a single daily dose : 5 g/kg(large dose group),2.5 g/kg(middle dose group)and 0.5 g/kg(small dose group).Testosterone content was measured by ELISA.mRNA levels of peripheral-type benzodiazepine receptors(PBR),PPARct and ABP were assayed by RT-PCR.Results Compared with control group:(1)ethanol feeding with daily doses of 5 g/kg,2.5 g/kg and 0.5 g/kg significantly decreased testosterone levels by 31.13%(P0.05)respectively,indicating that ethanol might impair testosterone synthesis;(2) mRNA levels of PBR were decreased in all three ethanol-treated groups(all P

Objective To discuss the effects of prophylactic chemotherapy on the outcomes and prognosis of invasive mole patients.Methods One hundred and fifteen invasive mole (IM) patients older than 40 years were registered in Peking Union Medical Collage Hospital.Eleven of them were treated with prophylactic chemotherapy before diagnosed as IM prophylactic chemotherapy group,while the other 104 cases received therapeutic chemotherapy after diagnosed as IM (non-prophylactic chemotherapy group).The general clinical data (including age,clinical stage,risk factor score),treatment,outcomes and relapse of patients were retrospectively compared between two groups.Results (1) The age of prophylactic chemotherapy group and non-prophylactic chemotherapy group were (47±5) versus (46±4) years old.Ratio of clinical stage Ⅰ-Ⅱ were 3/11 versus 29.8％ (31/104),clinical stage Ⅲ-Ⅳ were 8/11 versus 70.2％ (73/104).Ratio of risk factor score 0-6 were 11/11 versus 84.6％ (88/104),risk factor score ＞6 were 0 versus 15.4％(16/104).There were no significant statistical differences between two groups in age,clinical stage or risk factor score (all P＞0.05).(2) Treatment:the total chemotherapy courses between prophylactic chemotherapy group and non-prophylactic chemotherapy group (median 7 versus 5) were significantly different (Z=3.071,P=0.002).There were no significant statistical differences between two groups in the chemotherapy courses until negative conversion of β-hCG,consolidation chemotherapy courses,total therapeutic chemotherapy courses or ratio of hysterectomy (all P＞0.05).(3) Outcomes and relapse:between the prophylactic chemotherapy group and the non-prophylactic chemotherapy group,the complete remission rate were 11/11 versus 98.1％(102/104),the relapse rate were 0 versus 1.0％(1/102).There were no significant difference between the two groups in outcomes or relapse rate (P＞0.05).Conclusions Prophylactic chemotherapy does not substantially benefit the IM patients older than 40 years.Prophylactic chemotherapy may not significantly improve patients' prognosis,in which increased sample size is required in further study.

OBJECTIVE To investigate the prevalence of the antimicrobial and disinfectant-resistant genes from the clinical isolates of meticillin-resistant Staphylococcus aureus(MRSA) and meticillin-resistant Staphylococcus haemolyticus(MRSH).METHODS The identification and antimicrobial susceptibility test of MRSA and MRSH isolates were determined by MicroScan auto SCAN4.PCR was used for detecting antimicrobial and disinfectant-resistant genes.The minimal inhibitory concentration(MIC)and minimal bactericidal concentration(MBC)of benzalkonium bromide to staphylococci that carried qacA/B gene were determined by broth dilution method.RESULTS The positive rates of qacA/B,aac(6′)/aph(2″),aph(3′)-Ⅲ,ant(4′,4″),TEM,erm,and tetM from 24 MRSH strains were 37.5%,87.5%,33.3%,29.2%,95.8%,and 94.4%;and 91.7%.respectively,and 30.6%,91.7%,72.2%,8.3%,100%,94.4% and 91.7%,respectively.The MIC of benzalkonium bromide for MRSH and MRSA were both 32-128 mg/L,MBC for MRSH was 256-512 mg/L and for MRSA was 512-1024 mg/L.The MIC and MBC of benzalkonium bromide for standard strain ATCC25923 were 16 mg/L and 32mg/L,respectively.CONCLUSIONS Antimicrobial and disinfectant-resistant genes are commonly prevalent in MRSA and MRSH isolates.

Objective To investigate the changes of pulmonary capillary wedge pressure(PCWP) before and after off-pump coronary artery bypass graft(OPCABG) using transesophageal echocardiography(TEE). Methods Mitral valve flow(MVF) and pulmonary veinous flow(PVF) were measured in 46 patients before and after OPCAB using TEE and PCWP was detected by cardiac catheter. The correlations between indices derived from TEE and catheterization-measured PCWP and the differences before and after OPCAB were studied. Results There were obvious differences in the indices derived from TEE and PCWP which could reflect the left ventricular function. The most indices measured in PVF and MVF correlated with PCWP(r=(0.30)-(0.76),P
