Objective:To explore the associations of menopause with cardiovascular disease (CVD) and related metabolic disorders (including hypertension,diabetes or higher blood sugar,obesity,dyslipi-demia)in Chinese females aged 45 -59 years .Methods:Data were acquired from a national cross-sectional survey conducted in 201 3,China,which was also the second follow-up survey of China Health and Retirement Longitudinal Study (CHARLS).In the study,4 702 Chinese perimenopausal women aged 45 -59 years were enrolled,including 1 769 premenopausal women and 2 933 postmenopausal women.Information was collected from questionnaires of health status and functioning and physical exa-mination.General liner models were employed to calculate age-adjusted or age-and-body-mass-index-adjusted or multiple-factor-adjusted means and their 95% confidence intervals (95% CIs)of cardiovas-cular risk factors (CRFs).The comparisons of CVD and its risk factors according to menopausal status, and calculation of adjusted odds ratios (ORs)and their 95%CIs for the associations of menopause with CVD and its risk factors were performed by multivariate Logistic regression models separately.Results:After adjustment for age and other confounders (including body mass index,marriage,education,current smoking,drink alcohol more than once per month),statistically significant associations of menopause with cardiovascular disease,which referred to having a history of heart disease or stroke in this study, were observed in the participants (OR =1 .34,95% CI:1 .04 -1 .74);prevalence of hypertension (OR =1 .42,95%CI:1 .1 0 -1 .84),prevalence of CRFs clustering number≥2 (OR =1 .31 ,95%CI:1 .02 -1 .68)and average waist circumference level (87.1 1 cm,95%CI:86.81 -87.42 cm in post-menopausal group vs.86.41 cm,95%CI:85.99 -86.84 cm in premenopausal group)were presented higher in postmenopausal group,compared with the premenopausal one.However,diabetes or higher blood sugar (OR =0.96,95%CI:0.60 -1 .52),dyslipidemia (OR =0.84,95%CI:0.59 -1 .20) and obesity (OR =1 .06,95%CI:0.86 -1 .32)were not shown significantly statistically related to me-nopause,after excluding effect of age and other confounders.Conclusion:Postmenopausal women in China had worse CRFs profile than the premenopausal ones,which implied menopause might aggravate the CRFs epidemic and increase the risk of cardiovascular disease beyond effects of aging,which would increase the CVD burden during and after their middle ages.

Nasopharyngeal carcinoma (NPC), a common head and neck neoplasm in southern China,is mostly treated with radiotherapy, however, it can not be completely cured by chemoradiotherapy. Recent investigation on NPC suggests that the nasopharyngeal carcinoma stem cells can be differentiated to heterogeneous cancer cells that have a strong ability for self renovation and further contribute to the development and progression of tumor itself which is closely related to drug resistance, recurrence and metastasis of NPC. Wnt/β-catenin, Notch, Hedgehog, NF-κB and mTOR signaling pathways play important roles in cancer stem cells. Study on nasopharyngeal carcinoma stem cells targeted therapies and its related pathways provides a new strategy for the clinical treatment of NPC.

The PET tracer 5-([11C]methyloxy)-L-tryptophan (5-(11)CMTP) was prepared by nucleophilic fluorination and alkylation reaction via a two-step procedure in order to develop specific tumor probe. The biodistribution and microPET imaging of 5-(11)CMTP were executed. The results unveiled that the overall radiochemical yield with no decay correction was (14.6 ±7.2) %, the radiochemical purity was more than 95% and high uptake and long retention time of 5-(11)CMTP in liver, kidney and blood were observed but low uptake in brain and muscle were found, furthermore, high uptake of 5-(11)CMTP in tumor tissue was observed. It seems that 5-(11)CMTP will be a potential amino acid tracer for tumors imaging with PET.

AIM To investigate the effects of honokiol on ischemic neurological deficiency and on the scavenging ability of ischemia reperfusion (I-R) brain tissue for reactive oxygen species (ROS). METHODSCerebral ischemia was induced by middle cerebral artery occlusion (MCAO) in rats. I-R in mice were induced by blood stream pause in bilateral common carotid arteries for 30 min and reperfusion for 30 min. The activities of ROS scavenging enzymes were determined with colorimetric methods. RESULTS Intravenous honokiol in 5-50 μg·kg-1 significantly decreased the neurological deficiency score, and diminished cerebral infarction volume in rats. In I-R brain tissue of mice, intravenous honokiol in 7-70 μg·kg-1 evidently enhanced the activities of superoxide dismutase, catalase, glutathione peroxidase and peroxidase, and markedly lowered lipid peroxidative product malondialdehyde content. Moreover honokiol significantly increased Na+-K+-ATPase activity in I-R brain tissue. CONCLUSION Honokiol ameliorates the neurological deficiency behavior and diminishes infarction volume in MCAO rats; and enhances cerebral scavenging ability for ROS and Na+-K+-ATPase activity in cerebral I-R mice. It is indicated that honokiol is a protective agent for cerebral ischemia and I-R.

Methods Specific phosphorothioate antisense oligodeoxynucleotides targeting livin were synthesized and then transfected into 786-O cells. The expressions of livin mRNA were detected by RT-PCR. Expression and location of livin protein were observed by confocal laser scanning microscope (CLSM). Apoptosis rate of 786-O cells was investigated by flow cytometer. The activity of Caspase-3 was detected by colorimetric assay. Results After the transfection of ASODN, the expression of livin mRNA was decreased (P

Objective: To observe the influence on IL-1β and IL-2 in rat models with rheumatoid arthritis after moxibustion on Shenshu (BL 23) and Zusanli (ST 36) points, and to discuss the mechanism of moxibustion. Methods: Fifty male Wistar rats were divided randomly into 5 groups,control group, model group, drug group, moxibustion group, and laser group, 10 for each. Four groups except the normal group were built on the model of rheumatoid arthritis. The changes of body weight and plantar circumference were measured and the level of IL-1β、 IL-2 in sera were examined by ELISA. Results: Compared with the model group, the weight and plantar circumference of rats in the moxibustion group were improved significantly after treatment (P＜0.01), and the improvement of plantar circumference also had significant differences compared with the drug group and the laser group (P＜0.05). The level of IL- 1β、 IL-2 in sera were down regulated in the moxibustion group and the laser group, which had statistical differences compared with the model group (P＜0.05), but no statistical differences were found when comparing with the drug group. Conclusion: Moxibustion obviously improves the toe tumefaction of the rats with rheumatoid arthritis, which is better than CO2 laser of 10.6μm. On the aspect of decreasing the amount of IL-1β、 IL-2, CO2 laser of 10.6 μm is similar with moxibustion.

Shanghai began to strengthen the community health service system in 1997 , and had officially en-tered the period of “connotation construction” with the core policy of family doctor system in 2011 after the period of“service framework and network establishment” and“operational mechanism reform”. Through summarizing the poli-cy files related the family doctor system and based on 2013 report on monitoring and evaluation of family doctor system in Shanghai, the paper presented the progress of the system from aspects of system coverage, signature relationship, service mode and operational mechanism, and analyzed the development bottlenecks of the system from aspects of the policy itself, service principal, service supervision and service objects. Finally, the paper proposed some suggestions in order to give some references for further development of national general practitioner system.
