ObjectiveTo study the mechanism of differentiation of mesenchymal stem cells(MSCs) into neuron-like cells in vitro.MethodsMSCs of Wistar rats were separated and cultured, and then induced with DMSO and BHA in vitro. The specific marking proteins of neurons, glia and neural stem cells were detected before preinduction, at 24h after preinduction, at 6h, 24h, and 48h after neuronal induction.ResultsAfter the inducement, many MSCs turned into bipolar,multipolar and taper,and then intersected as network structure. Nestin was strong positive at 6h after neuronal induction, and decreased at 24h, 48h after the induction. NeuN was present at 6 h after neuronal induction, and increased at 24h, 48h after the induction.ConclusionMSCs can be induced into neural stem cells(NSCs) at first, and then differentiate into neuron-like cells in vitro.

OBJECTIVETo explore the mechanism of electroacupuncture at "Neiguan" (PC 6) antagonizing myocardial ischemia injury.

METHODSForty rabbits were randomly divided into 4 groups, model control group, naloxone control group, electroacupuncture plus cerebral spinal fluid group, and electroacupuncture plus naloxone group, 10 rabbits in each group. The effects of electroacupuncture at "Neiguan" (PC 6) after injection of naloxone into the paraventricular nucleus (PVN) of the hypothalamus on myocardial ultrastructure, II lead ECG and transmembrane potentials of the ischemic myocardial cell in the rabbit of myocardial ischemia were investigated.

RESULTSThe injection of naloxone into PVN has no effect on myocardial functions in the normal rabbit and a little effect on ischemic myocardial functions, but at 60 min after myocardial ischemia, this has a certain protective action on myocardial functions (P < 0.05); electroacupuncture at "Neiguan" has obvious protective action on ischemic myocardium, which can be reduced by injection of naloxone into PVN (P < 0.05), but can not be blocked.

CONCLUSION(1) PVN plays an important role in the process of antagonizing myocardial ischemia by electroacupuncture at "Neiguan"; (2) endogenous opioid pepetides in PVN are involved in the acupuncture effect of antagonizing myocardial ischemia; (3) other transmitters in PVN and other nucleus groups in the center also can produce obvious effects in the antagonism to myocardial ischemia by electroacupuncture at "Neiguan".

OBJECTIVETo explore the relationship between serum apolipoprotein A5 (ApoA5) and lipid profile or high sensitive C-reactive protein (hs-CRP) in patients with acute coronary syndrome (ACS).

METHODSSerum apoA5 and hs-CRP levels were measured by ELISA and immunoturbidimetry in control subjects (n = 232), patients with stable angina (SA, n = 127), unstable angina (UA, n = 116) and acute myocardial infarction (AMI, n = 112). Triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were also measured.

RESULTSCompared with controls [(108.7 +/- 23.2) microg/L] and SA patients [(78.3 +/- 20.2) microg/L], serum ApoA5 level was significantly increased in UA [(340.6 +/- 63.5) microg/L] and AMI patients [(373.2 +/- 73.8) microg/L] (all P < 0.05). ApoA5 was positively correlated with TG (r = 0.63 and 0.67, respectively, all P < 0.05) and hs-CRP (r = 0.57 and 0.55, respectively, all P < 0.05) in UA and AMI patients but there were no significant correlations between ApoA5 and TC, HDL-C and LDL-C in ACS patients (all P > 0.05).

CONCLUSIONIncreased serum apoA5 level and the positive correlation between ApoA5 and serum TG and hs-CRP in ACS patients might reflect increased inflammation responses in ACS patients.

OBJECTIVETo explore the impact of being informed of HIV infection before or after pregnancy on the prevention of mother-to-child transmission (PMTCT) HIV interventions uptake.

METHODSFrom 2005 to 2009, a tatal of 5552 HIV-infected pregnant women and their 5894 pregnancies in Henan, Guangxi, Yunnan and Xinjiang province were investigated using the method of a cohort study. The social-demographic characters (the objects were divided three age groups 15-, 25-, 35-49), the period identified to be HIV positive, the outcome of pregnancy and the PMTCT interventions including uptake of antiretroviral drugs (ARVs) were investigated. Through single-factor and non-conditional logistic regression model, the factors influencing the utilization of PMTCT services were analyzed.

RESULTSOf HIV-infected pregnant women, 84.5% (4979/5894) were under 35 year-old, and 56.0% (3108/5552) of them were Han group and the percentage of peasant or unemployment was 85.1% (4727/5552). 86.8% (4815/5552) of these women had junior high school education or less, and the proportion of women knowing HIV infection before the pregnancy was 31.2% (1836/5894). Of HIV positive pregnant women, 31.7% (1869/5894) chose to terminate the pregnancy artificially, and the percentage was 43.8% (805/1836) among those knowing HIV infection before pregnancy. The proportion of the ARVs uptake among HIV positive maternities who delivered was 80.0% (3046/3808), while the percentage among those knowing HIV positive before pregnancy was 92.3% (883/957), which was much higher than it (75.9% (2163/2851)) among the pregnant women knowing HIV infection just during the pregnancy (χ(2) = 120.39, P < 0.05). The results of multivariate analysis showed that the proportion of ARVs' uptake was high among those HIV positive pregnant women knowing to be HIV-infected before pregnancy (versus knowing to be HIV-infected after the pregnancy, OR = 3.91 (95%CI: 3.03 - 5.05)) and age of 15 to 24 year-old (versus age of 35 - 49 year-old, OR = 0.75 (95%CI: 0.57 - 0.98)).

CONCLUSIONIt will promote the HIV-infected pregnant women to receive the PMTCT intervention services if they know their HIV sero-status before pregnancy.

Objective To evaluate the year-round vaccine persistency of trivalent inactivated influenza vaccine (TIV) among elderly aged 65 years and above. Methods Searching "National Center for Biotechnology Information" , "Cochrane Library, CL", "China Biology Medicine disc", "China National Knowledge Infrastructure", "Wanfang Database", the studies of the year-round vaccine persistency of trivalent inactivated influenza vaccine among the elderly aged 65 years and above were included, and meta-analysis were made by Stata 11.0 software. Results A total of 17 studies were included. Compared with the antibody level before immunization, the standard mean differences (SMDs) of geometric mean titer (GMT) was 0.10 (95%CI: -0.12-0.32), 0.57 (95%CI: 0.23-0.91), 0.47 (95%CI:-0.20-1.15) and -0.27 (95%CI: -0.51--0.04) for the total haemagglutination inhibition (HI) antibody, the HI antibody of A/H1N1, the HI antibody of A/H3N2 and the HI antibody of B, respectively, by 360 day. The risk differences (RD) of sero-protection rate (SP) was 0.06 (95%CI: -0.04-0.16), 0.09 (95%CI: -0.15-0.33), -0.08 (95%CI: -0.28-0.13) and 0.00 (95%CI: -0.13 - -0.13) for the total haemagglutination inhibition (HI) antibody, the HI antibody of A/H1N1, the HI antibody of A/H3N2 and the HI antibody of B, respectively, by 360 day. Conclusion The HI antibody responses following TIV vaccination do not reliably persist year-round in the elderly aged 65 years and above . Clinic trials and health economic evaluation studies are needed to assess the feasibility and cost-effectiveness of multiple doses schedule of TIV in elderly.
