each group were sacrificed, respectively. Distributions of BrdU positive cels and ChAT positive cels were detected by S-P immunohistochemical method. The learning and memory abilities of rats were detected by Morris water maze system.
RESULTS AND CONCLUSION:BrdU positive cels were mainly distributed in the cortex and hippocampus, especialy around the blood vessels, and there was the presence of focal aggregation. A smal amount of BrdU positive cels were observed in the basal ganglia and thalamus as wel as in the ependyma. BrdU positive cels were counted at different time after operation. The number of BrdU positive cels decreased with time, and only a smal number of BrdU positive cels were observed at 60 days after transplantation. The number of ChAT positive cels at different time after transplantation was ranked as folows: neural stem cel transplantation group > model group > sham operated group (P < 0.05). Compared with the model group, the time for searching the platform was significantly lower in the neural stem transplantation group and sham operated group, but the number of crossing the platform was significantly higher in the neural stem cel transplantation group and sham operated group (P < 0.05). The results show that neural stem cels could be transplanted into the rats with vascular dementia, and the cels could survive and migrate in the brain of rats and significantly improve the learning and memory ability. This mechanism may be related to the differentiation and growth of cholinergic neurons in the hippocampus.

Objective To study the association between three single nucleotide polymorphisms (SNP; rs2241766,rs1501299 and rs12495941) variants of the adiponectin gene (ADIPOQ) and polycystic ovary syndrome (PCOS) in PCOS family trios.Methods A total of 224 unrelated PCOS probands,their biological parents were recruited.Anthropometric variables such as waist circumference (WC),hip circumference (HC),height and weight were measured in all subjects during the first visit to the outpatient department.Body mass index (BMI) and waist-hip ratio (WHR) were calculated.Serum fasting glucose (FBG),fasting insulin (FINS),total cholesterol (TC),triglycerides (TG),low-density lipoprotein and highdensity lipoprotein cholesterol (HDL) levels were measured.PCOS patients were divided into two groups based on BMh group A (BMI＜25 kg/m2) and group B (BMI≥25 kg/m2).Parents of PCOS patients were accordingly categorized into group C,D (fathers) and group E,F (mothers).The transmission disequilibrium test (TDT) was used to analyze the association between three SNP of ADIPOQ and PCOS.Results (1) A significant positive association was detected between SNP rs1501299 and PCOS (x2=7.093,P=0.008).However we failed to find significant overtransmission of the other two SNP rs2241766 and rs12495941 from parents to PCOS offsprings (x2=1.620,P=0.203; x2=0.713,P=0.398).(2) Linkage disequilibrium (LD) was analyzed in the subjects,rs1501299 and rs2241766 were in weak LD (r2=0.063,D'=0.621).(3) The levels of WC,HC,WHR,testosterone,TG,HDL and FINS were significantly differences between obese and lean PCOS patients (P＜0.05).While in fathers we only found WC,HC,TC levels being statistically different (P＜ 0.05).Mothers of obese PCOS patients had increased levels of FINS compared with mothers of lean PCOS patients (P＜0.05).The genotype frequencies of the three SNP were not different in obese and lean PCOS patients and their parents (P＞0.05).Conclusions TDT confirms that SNP rs1501299 in the ADIPOQ is significantly associated with the risk of PCOS in the Chinese Han population.The three SNP of the ADIPOQ were not associated with the obesity of PCOS.

Objective To assess the carotid elasticity using wave intensity(WI) in subjects with different plasma glucose level.Methods 107 subjects were enrolled in this study,according to their plasma glucose levels,subjects were categorized as normal plasma glucose group (group A),normal plasma glucose in higher level group (group B) and pre-diabetes group (group C).Carotid WI examination was performed and analyzed.The parameters included magnitude of the peak during late systole (W2),negative area during the mid-ejection (NA),and stiffness parameter (β),pressure strain elasticity modulus (Ep),arterial compliance(AC),augmentation index(AI),one point pulse wave velocity(PWVβ).Results Compared to group A,W2,β,Ep,PWVβ increased significantly while AC decreased in group C(P ＜0.05),but there was no obvious difference of NA between two groups.Furthermore,this statistically difference was not found in group B(P ＞0.05).Conclusions Carotid elasticity have been altered in pre-diabetes group which can be evaluated by WI,but no marked change is observed in normal plasma glucose of higher level group.

OBJECTIVE:To investigate the effects of different elutions of Hyssopus cuspidatus on smooth muscle contraction of isolated tracheal in Guinea pigs. METHODS:Isolated tracheal rings were prepared and soaked in Krebs-Henseleit,using acetyl-choline(ACh,1×10-7 g/mL)or histamine(His,1×10-6 g/mL)to induce contraction of tracheal rings,then the effects of H. cuspi-datus water elution and 30%,50%,60%,70%,95%ethanol elutions with mass concentrations of 0.08,0.16,0.32,0.64,1.28, 2.56 mg/mL on contraction of tracheal rings were respectively investigated. Contraction curves were recorded and antispasmodic rates were calculated. Tests were treated with saline as blank control and aminophylline (0.08 mg/mL) as positive control. RE-SULTS:Compared with blank control,0.16-2.56 mg/mL 30%,50% ethanol elution,0.32-2.56 mg/mL 60% ethanol elution and 0.64-2.56 mg/mL 70%,95% ethanol elution can obviously inhibit ACh-induced contraction of tracheal rings,antispasmodic rates were obviously increased(P<0.05 or P<0.01);0.32-2.56 mg/mL water elution and 30%,50% ethanol elution,0.16-2.56 mg/mL 60%,70% ethanol elution and 1.28-2.56 mg/mL 95% ethanol elution can obviously inhibit His-induced contraction of tracheal rings,antispasmodic rates were obviously increased (P<0.05 or P<0.01). The effects of 2.56 mg/mL 60% ethanol elution ap-proach to aminophylline. CONCLUSIONS:Different elutions of H. cuspidatus has certain antagonistic effect on the ACh-induced or His-induced smooth muscle contraction of isolated tracheal in Guinea pigs;60% ethanol elution shows the strongest effect, which has similar effects with aminophylline at high mass concentration.

Object To study the effect of puerarin on the expression of inflammatory factors and miR-155-3p in human umbilical vein endothelial cells ( HUVEC) induced by visfatin.Methods The HUVEC cell injury model was es-tablished with visfatin.Cell proliferation was measured by MTT assay.Cell apoptosis was detected by flow cytometry.The level of CRP and NF-κB was detected by ELISA, and the expression of miR-155-3p was detected by RT-PCR.The expres-sion of myeloid differentiation factor 88 ( MyD88) was identified by western blotting.Results Visfatin induced cell prolif-eration and inhibited apoptosis in HUVEC, meanwhile the expressions of both CRP and NF-κB were significantly increased, compared with that of the control group (P<0.01).Puerarin at moderate and high concentrations obviously reduced the HUVEC injury induced by visfatin, mainly through down-regulating the expression of CRP and NF-κB, as well as up-regu-lating the level of miR-155-3p in the HUVEC.MiR-155-3p mimic markedly decreased the level of MyD88, CRP and NF-κB in the HUVEC induced by visfatin (P<0.05).Conclusions Pueprarin obviously alleviates HUVEC injury induced by visfatin, probably related to down-regulating the level of MyD88, CRP, NF-κB, and up-regulating the expression of miR-155-3p in HUVEC.
