Objective To investigate the possibility that TGF ? may also influence the basal and FSH stimulated production of estradiol and progesterone by granulosa cells in vitro. Methods Granulosa cells were obtained from infertile patients undergoing in vitro fertilization and embryo transfer treatment and cultured with serum free supplemented HAM′s F 10 medium(control) or increasing concentrations of TGF ? 1,2 in the absence or presence of FSH (96 U/ml). The media were collected in 24, 48, 72 and 96 h intervals and assayed for estradiol and progesterone. Results Increasing amounts of TGF ? had a significant effect on estradiol production, especially in the presence of FSH,The estradiol value was evaluated from (12 077.9?5 835.3) pmol/L and (13 656.1? 8 404 3) pmol/L to (16 606.8?7 993.3) pmol/L and (19 480.4?913.8) pmol/L. TGF ? inhibited FSH stimulated progesterone but not unstimulated progesterone release ( P

Objective To explore the composition situation of the risk factors of patients with stroke in Huainan area. Methods 471 continuous registration and hospitalized patients with stroke in Huainan were selected,of which,362 cases were ischemic stroke,109 cases were hemorrhagic stroke,and the known risk factors were statistically analyzed. Results Of all patients,the incidence of hypertension was first(69. 3% was in ischemic stroke, 77. 9% was in hemorrhagic stroke) ,and hypertension was the most important risk factors. The composition of risk factors in stroke patients of different gender were different,and the smoking,drinking problem was more prominent in male patients (51.1% ,33.2%respectively)than that in female patients(5.1% ,2.0% respectively) (x2 =111-81,67.62, all P＜0.01) ;The incidence of diabetes, heart disease, atrial fibrillation was higher in female patients (37. 6% ,31. 9% ,19.3%respectively) than that in male patients (22.3% ,20.4% ,8.8% respectively) (x2 = 13. 12,8.09,11. 12,all P＜0.01). Hypertension,diabetes accounted for only 40.8% and 47.4% of patients taking regular medication. Atrial fibrillation was more common in patients with hemorrhagic stroke. Conclusion Controlling blood pressure and blood sugar was still important in the primary prevention and secondary prevention of stroke in the region. People of different gender should be targeted for individual health education, and promoting a healthy lifestyle should be paid attention, so as to the occurrence of stroke could be effectively prevented.

Objective To observe the effects of parecoxib sodium on laparoscopic cholecystectomy ( LC ) patients after remifentanil fast track anesthesia.Methods 120 patients underwent general anesthesia for laparoscopic cholecystectomy were divided into two groups using random number table,60 cases in each group.The observation group was injected parecoxib sodium 40mg+saline solution 5 mL,while the control group was injected only saline so-lution 5mL prior to induction of anesthesia.The heart rate,mean arterial pressure,awaked time,pain score,agitation score and adverse reaction were compared.Results 5, 15, 30min after extubation, heart rate were ( 75.7 ± 4.8)times/min,(79.3 ±6.2)times/min,(74.2 ±5.2)times/min in the observation group and (85.2 ±3.8)times/min, (88.2 ±5.9)times/min,(86.1 ±6.2)times/min in the control group,and the mean arterial pressure were (103.5 ± 11.3)mmHg,(104.7 ±12.6)mmHg,(108.4 ±12.7)mmHg in the observation group and (132.3 ±16.3)mmHg, (135.2 ±14.6) mmHg,(133.6 ±11.8) mmHg in the control group,there were statistifically significant differences (t=4.722,4.357,4.236,4.732,4.367,4.063,all P <0.05).The pain score,agitation score were (2.5 ± 0.9)points,(1.4 ±0.8) points in the observation group,which were lower than (4.2 ±1.2) points,(3.2 ± 1.2)points in the control group(t =4.232,5.234,all P<0.05).Conclusion Parecoxib sodium can reduce the fast-track anesthesia agitation and pain,improve hemodynamics and stress response in LC patients.

Objective: To investigate quantification of expression of LTB4 inducing IL-1? and TNF-? at mRNA level in synovial membrane cells of rheumatoid arthritis. Methods: Primary cultured synovial cells from RA patients were treated with exogenous LTB4,MK-886(inhibitor of 5-lipoxygenase activating protein) and Bestatin(inhibitor of leukotriene A4 hydrolase) in the presence of LIT respectively, expressions of TNF-? and IL-1? were detected at mRNA level by Real-time Quantitative PCR. Results: Expressions of basic TNF-?(TNF-?/GAPDH) and IL-?(IL-?/GAPDH) at mRNA level in primary cultured synovial cells were 0.02?0.00 and 0.16?0.01 respectively. LTB4(10~ -9 mol/L-10~ -8 mol/L) was shown to induce dose-dependent increase of mRNA expression of TNF-?.(7-15 times) and IL-1? (1 time) , endogenous product of LTB4 by LIT significantly increased mRNA expressions of TNF-? (145 times) and IL-1?(12 times) respectively. LIT-treated synoviocytes with addition of MK-886 (5-LOX exciting protein FLAP inhibitor) (1-10 ?mol/L) were inhibited to secrete LTB4 dose-dependently, following the markedly down-regulated expressions of TNF-? (15%-66%) and IL-1? (41%-71%) at mRNA level . Bestatin(100 mg/L) could also remarkably diminish LTB4-induced mRNA expressions of TNF-?(86%) and IL-1?(79%). Conclusion: LTB4 of synovial membrance cells in rheumatoid arthritis could induce expressions of TNF-? and IL-1? at mRNA level, and their expression at mRNA level had been quantified successfully. It is a beneficial help to quantify all kinds of cytokines in methodology.

Objective To verify the flow field performance of the air dynamic wind tunnel. Methods The performance of the flow field was evaluated by testing the flow speed of sample-point on the sample-transect of the tunnel. Results Among the flow range of the tunnel, the relative deviations of the speeds of each sample-point on the sample-transect were less than 10%. When the flow rate was set, the relative deviations of the sample-transect average speed in different test period were less than 10%. The ratio of average wind velocity of upper reach to down reach of the tunnel was between 0.92 and 1.03. Conclusion The flow field of the air dynamic wind tunnel is even, stable and coincident.

Objective To sbserve the effect of sirolimus-eluting stent in actual clinical practice. Methods The study included 263 patients who had implanted the cypher stents from December 2002 to May 2004. The incidence of MACE was followed up in all patients 8?2 months after stent implantation by means of telephone or out-patient department visit. Evaluation of the therapeutic effect was also made in the diabetes subgroup and different types of lesions, including left main, bifurcation, chronic total occlusion, diffuse disease, in-stent restenosis, littlie vessel, acute occlusion, ostial lesions, and just A-type lesions. The rate of restenosis was observed in all of the lesion. Results Among 246 patients, all patients were successfully implanted with the cypher stents, 93.5% patients had been followed up, 10 (3.8%) patients had MACE. 139 (52.6%) patient were revised by angiography. The total rate of restenosis was 10.1%, and among it 12.9% was diabetes mellitus patients, 11.1% with chronic total occlusion, 11.3% with little vessel lesion, 10.0% with diffuse lesion, 22.2% with left main lesion, 18.1% with bifurcation, 11.1 with CTO 9.1% with ostial lesions, and 8.7% with A-type lesion lesion. Conclusion Cypher stent implantion was safe and effective in actual clinical proctice. The incidence rate of MACE was low in lesions such as chronic total occlusion, diffuse disease, in-stent restenosis, littlie vessel, acute occlusion, ostial lesions, and A-type lesion. It may be beneficial for patients who had left main, bifurcation, in-stent restenosis.
