Objective Discbuss the hypertension prevalence rate in the Wuhan male taxi drivers and the dangerous factor to provide the basis for its professional publie health work. Methods The Wuhan male taxi drivers were carried on the healthy physical examination who in the Hubei province medicine medical examination center during 2005-2007 and were carried on the epidemiology statistical analysis. Results The Wuhan male taxi drivers hypertension prevalence rate is 28.28%. That is higher than the common crowd. Hypertension leaves outside the heredity factor and be closely correlated with the age of harnesses, the body weight index, and so on. Conclusions The Wuhan male taxi drivers'hypertension prevalence rate is unoptimistic. We should take the synthesis preventing and controlling measure to reduce this crowd hypertension prevalence rate.

Objective To evaluate the feeding effect of semi-demand feeding and abdominal massage on the feeding process, feeding performances and clinical safety (including the time of returning to birth weight, feeding tolerance, apnea). Methods A total of 120 preterm infants that met inclusion criteria of the study were randomly assigned to three groups, and each group had 40 cases. Control group:received standard feeding care. Semi-demand feeding group: received 5-10 minutes of oral motor intervention every time before feeding(including oral stimulation and non nutritional sucking), then decided feeding methods according to its consciousness behavior state. Semi-demand feeding combined abdominal massage group: received both semi-demand feeding and abdominal massage before feeding. Observed and recorded the three groups′ transition time, whether there were statistically significant differences in feeding performance and clinical safety. Results The feeding transition time was (11.55± 4.69), (10.98±3.85), (8.50±3.87)d in control group, semi-demand feeding group and semi-demand feeding combined abdominal massage group, and there were significant differences (F=6.088, P=0.003). In terms of feeding performance, the feeding efficiency were (7.27 ± 2.65), (9.74 ± 2.63), (9.52 ± 2.13) ml/min, the feeding proficiency were (66.31 ± 14.51)%, (76.64 ± 12.46)%, (82.26 ± 10.65)%, the volume transfer were (63.99 ± 11.02)%, (80.16 ± 14.41)%, (84.97 ± 11.16)% in control group, semi-demand feeding group and semi-demand feeding combined abdominal massage group, and there were significant differences (F=12.189, 16.383, 31.959, all P < 0.01).Among the clinical safety, the time of restoration of birth weight were (10.55 ± 1.99), (9.28 ± 1.77), (10.05 ± 2.46) d in control group, semi-demand feeding group and semi-demand feeding combined abdominal massage group, and there were significant differences(F=3.759, P=0.026). The incidence of feeding intolerance were 50.0%(20/40), 40.0%(16/40), 22.5%(9/40), and there were significant differences(χ2=6.613, P=0.037). The incidence of apnea were 37.5%(15/40), 20.0%(8/40), 15.0%(6/40), and there were significant differences(χ2=6.093, P=0.048). Conclusions The combined intervention methods could accelerate the feeding process, improve feeding performance as well as reduce the incidence of feeding intolerance and apnea. Hence, semi-demand feeding combined abdominal massage is a recommended choice for clinical use.

Objective To transplant the umbilical cord mesenchymal stem cells(UCMSCs) derived from human umbilical cord into cisterna magna of hypoxic-ischemic encephalopathy(HIE) rat model,and to observe their survival,proliferation and differentiation in the rat brain.Methods UCMSCs were isolated from human umbilical cord of babies delivered after full-term normal cesarean section,and labeled by bromodeoxyuridine(BrdU).Pregnant rats were randomly divided into experimental group(n=6) and control group(n=1).HIE models were built by ligating both sides of the uterine arteries of full-pregnant rats(21 days) in experimental group rats for 15 minutes.The neonatal rats in experimental group were divided into stem cells group(n=24) and PBS group(n=19) at random.The labeled UCMSCs were injected into cisterna magna of the rats in stem cells group,while PBS was injected into the rats of PBS group.In 1,2,3 and 4 weeks after transplantation,the brain tissue section slides were immunohistochemically stained with antibodies against BrdU,Nestin,neuron specific enolase(NSE) and glial fibrillary acidic protein(GFAP),and thionin.Control group with normal delivery was tested as concurrent control.Results At 1 week after transplantation,BrdU,Nestin,NSE and GFAP positive cells were found in the hippocampal dentate gyrus of the rats in stem cells group rats.The number of BrdU-positive and Nestin-positive cells increased(Pa0.05).The NSE-positive and GFAP-positive cells gradually increased from 1-4 weeks post transplantation and comparisons between groups had statistical significance(Pa

OBJECTIVETo investigate the inhibitory effects of OMT on TGF-β1-induced CFBs proliferation, and then explore the mechanism.

METHODThe experiment was randomly divided into 6 groups as following: control group (serum free DMEM), model group (20 μg x L(-1) TGF-β1), OMT low dose group (1.89 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT medium dose group (3.78 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT high dose group (7.56 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), SB203580 group (p38MAPK blocking agent, 1 x 10(-5) mol x L(-1) + 20 μg x L(-1) TGF-β1). Vimentin of CFBs was identified by immunocytochemical methods, α-SMA of myFBs as well. Inhibitory effects of OMT on CFBs proliferation was detected by the MTT assay. Picric acid Sirius red staining was analyzed collagen type I and collagen type III deposition. Western blot was determined the expression of p38MAPK, p-p38MAPK, collagen type I and collagen type III.

RESULTMTT results showed that OMT significantly inhibited CFBs proliferation induced by TGF-β1 (P < 0.01) α-SMA immunocytochemical experiments suggested that OMT could protect against the CFBs proliferation. OMT could significantly decrease the deposition of collagen type I and collagen type III by Western bloting and picric acid Sirius red staining. Western blot results showed that TGF-β1 enhanced p38MAPK phosphorylation, however OMT attenuated the phosphorylation of p38MAPK induced by TGF-β1 (P < 0.01).

CONCLUSIONOMT can inhibit the CFBs proliferation induced by TGF-β1, and its mechanism may be involved in inhibiting p38MAPK phosphorylation.
