To evaluate the differences of Ophiopogonjaponicus from different cultivations, the metabolomics based method was conducted to compare the effects of Hangmaidong and Chuanmaidong (Chinese name) on plasma endogenous metabolites of normal rats. Data were collected by ultra performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-Q-TOF/MS), and were analyzed by multivariate statistical method, such as Principal Component Analysis and Orthogonal Signal Correction Partial Least Square Discriminant Analysis. Results revealed that the plasma metabolites profiling of low and middle dose group of Chuanmaidong were similar to the control group, but different from the high dose group obviously. Meanwhile the high, middle and low dose groups of Hangmaidong were different from control group notably, and the difference is dose dependent. Lysophosphatidylcholines, the possible endogenous metabolites which contribute to the classification most significantly, are closely related to cardiovascular system diseases. Compared with the group of Chuanmaidong, Hangmaidong has greater impact on the plasma metabolic profiling of normal rats. Hangmaidong and Chuanmaidong showed significant differences pharmacodynamically.

Objective To determine the relationship between serum testosterone level and lean body mass, body fat content, and bone mineral density (BMD) . Methods The study involved 185 healthy females in Changsha, aged 45 ～81. Fasting serum testosterone was measured by radioimmu-noassay. Hologic QDR 4500A fan beam X-ray bone densitometer was used to measure the BMD of anteroposterior lumber (AP, L_(1～4)) and total hip, to measure the bone mineral content, BMD, body fat content and muscle tissue weight of head, trunk, ribs, pelvis, spine, upper limbs, lower limbs and the total body. Body weight, lean body mass and body fat percentage were calculated. SPSS 11.0 software was used to conduct regression analysis. Results (1) Serum testosterone showed no correlation with lean body mass, body fat content, and body fat percentage. (2) Serum testosterone was positively related with the BMD of lumbar spine and hip, but showed no correlation with the BMD after adjustment of age and years since postmenopause. (3) Lean body mass showed significant positive correlation with the BMD of different sites. Total body fat content showed positive correlation with the BMD of total hip, while body fat percentage showed negative correlation with the BMD of the whole body. Conclusion Keeping lean body mass benefits postmenopausal women to maintain bone mineral content, and taking androgen should still be cautious.

Background and Objective Keshan disease is clinically characterized as a dilated eardiomyopathy. We analyze the prevalence trend during last decade of hypertension and Keshan-disease in Yangzhuang village which was a Keshan-disease epidemic area.Method The survey including medical history,blood pressure and ECG were carried out every two years during the follow up 13 years.Results During follow up period,the total detection rate(hypertension:13.4 % vs Keshan-disease:10.7 %,?~2=8.555,P=0.002)and the accumulative rate of hypertension were higher than those of Keshan-disease,which was on the contrary to that before 1993,when increasing rate of Keshan-disease was higher than hypertension.Furthermore,the accumulative increasing rate of hypertension was 240.0%,which was higher than the national average level during corresponding period with no significant differences between female and male.Conclusion The detection rate of hypertension in Keshan disease epidemic area was higher than the average rate nation-wide.Whether the hypertension prevalence was re- lated to Keshan-disease needs further investigation.

OBJECTIVETo investigate the optimal starvation conditions of human umbilical vein endothelial cells (HUVECs) and establish a highly efficient and stable method for separating HUVECs.

METHODSHUVECs harvested from human umbilical cords by digestion with 0.1% collagenase II for 15 min were cultured in endothelial culture medium (ECM) containing 5% fetal bovine serum (FBS), 1% endothelial cell growth factor (ECGS) and 1% penicillin/streptomycin solution(P/S) at 37 degrees celsius; in 5% CO2. The cells were observed for cell morphology under an inverted microscope and identified with immunofluorescence assay. The purity of HUVECs was detected using flow cytometry (FCM). The cell cycles of HUVECs cultured in the presence of 0, 0.1%, 0.5%, and 1% FBS for 0, 6, 12, 18, and 24 h were analyzed with flow cytometry.

RESULTSs The purity of HUVECs harvested by digestion with 0.1% collagenase II reached 99.67%. The primary HUVECs showed a cobblestone or volute appearance in vitro. Immunocytochemistry showed that HUVECs highly expressed VIII-related antigen. Cell culture in the presence of different concentrations of FBS for 6 h resulted in 70% G0/G1 phase cells, which increased to 80%-90% at 12 h of cell culture, and further to around 95% at 18 and 24 h.

CONCLUSIONDigestion with 0.1% collagenase II can obtain high-purity primary HUVECs. Culturing HUVECs in serum-free medium for 12 h can result in a high purity (over 80%) of G0/G1 phase cells.

Objective To investigate the prevalence of unintended pregnancy (UP) and exploring the risk factors of UP for married women of child-bearing age from Qingshan district,Wuhan.Methods A cross-sectional study was adopted in this study.Cluster sampling method was used with 3256 women recruited,in 2010.Information on history and risks related to social-demographic factors of UP were collected,using a self-administered questionnaire.Results Of the 3256 participants,over half of them (53.8％) reorted ever having had the history of UP and 9.1％ reported UP in the past year.Rate of UP in the past year for different age cohorts (18-30,31-40,41-49 years) were 31.8％,10.5％ and 1.8％ respectively.The most frequently reported reason for UP across all the age cohorts was "Did not use any contraceptive methods",with proportions on the reason that reported by women at 18-30,31-40 and 41-49 year-olds,were 69.7％,51.1％ and 42.4％ respectively.The second frequently reported reasons for UP were "Failure of traditional contraception" for younger cohort ( 18-30 years:13.0％ ) and "IUD dropped or pregnancy with IUD" for older-age cohorts (23.4％ at 31-40 year-olds and 37.0％ at the 41-49 year-oplds).The most frequently cited reason for "Did not use any contraceptive methods" was "Believe we were lucky so far,not to get pregnant" (59.6％).The risk factors of UP were being at older age,experiencing sex debut at younger age and got married at younger age.Conclusion The prevalence of lifetime UP history was high among women at child-bearing age from Qingshan district,Wuhan.Reproductive health services and interventions should be taken according to the needs from different age cohorts of women.Younger cohort of women should receive more attention.

OBJECTIVETo evaluate the prognostic factors in treating primary liver cancer (PLC) patients by Pi-strengthening and qi-regulating method (PSQRM), thus providing evidence and optimizing Pi-strengthening and qi-regulating program.

METHODSClinical data of 151 PLC patients treated by PSQRM at Oncology Department, Guangdong Provincial Hospital of Traditional Chinese Medicine from May 2007 to March 2009 were retrospectively analyzed. The univariate analysis was determined to analyze possible prognostic factors. Selected key factors were introduced into the COX proportional hazard model, and multivariate analysis was carried out.

RESULTSThe 1-year survival rate was 21.85%, the median survival time was 6.80 months, and the mean survival time was 8.98 months. The univariate analysis showed that Chinese medicine (CM) syndrome types, clinical symptoms at the initial diagnosis, ascites, tumor types, ratios of foci, portal vein tumor thrombus, intrahepatic metastasis, a-fetoprotein (AFP) levels, total bilirubin classification, albumin classification, Child-Pugh classification, and domestic staging of liver cancer were significant prognostic factors (P < 0.05). The statistic data of multivariate analysis indicated that CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer were independent factors influencing prognosis (P < 0.05).

CONCLUSIONThe prognosis of PLC treated with PSQRM is determined by multiple factors including CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer.
