新翻瓣术式拔除下颌阻生智齿的疗效观察

目的 探讨新的翻瓣术式在拔除下颌阻生智齿中的效果.方法 将184例智齿随机分为两组,新术式组89例采用新术式翻瓣,传统术式组95例采用传统角形切口翻瓣,翻瓣后采用去骨、分牙等通用方法拔牙.结果 两组比较,出血、肿胀、感染等术后并发症没有显著性差异,但新术式组的切口缝合时间明显小于传统术式组.结论 与传统术式相比,新翻瓣术式缝合容易,术后缝合时间显著缩短,且术后恢复好,没有龈裂形成、牙龈退缩、牙周袋形成,值得推广.     

体外养卵祝你好“孕”

由于高龄妇女机能退化,想要自然怀孕比较困难,所以。打排卵针就受到了众多想当妈妈的高龄女星的追捧。如39岁的港星黎姿,就是靠定期注射“超级排卵针”,生下一对双胞胎：而急切希望当上妈妈的刘嘉玲,也曾经试过用打排卵针来增加受孕机会,却最终没有成功。但事实上,李嘉欣能顺利诞下儿子。是靠另一种“助产”方式——体外养卵。     

土槿皮乙酸诱导大鼠神经胶质瘤C6细胞株凋亡

目的:研究土槿皮乙酸诱导大鼠神经胶质瘤C6细胞株凋亡及其机制.方法:采用MTT法检测0、0.625、1.25、2.5、5、10、20、40、80 μmol/L不同终浓度PAB对C6细胞增殖能力的影响,激光扫描共聚焦显微镜观察AO/EB荧光染色后细胞的凋亡情况,流式细胞术检测碘化丙啶(PI)染色后细胞周期的变化,免疫组化法测定C6细胞的凋亡相关蛋白Bcl-2的表达.结果:MTT结果显示,PAB呈时间剂量依赖性抑制C6细胞的生长.PAB处理24、48和72 h后,对C6细胞的半效致死剂量(IC50)分别为39.811、23.306和7.360 μmol/L.5.0、10.0、20.0 μmol/L PAB作用C6细胞72 h后的凋亡率分别为(50.5±0.7)%、(63.5±2.3)%和(80.0±1.2)%,与对照组(12.0±1.6)%比较均明显升高,差异有统计学意义(P<0.05).流式细胞仪检测结果显示5.0、10.0、20.0 μmol/L不同浓度PAB作用C6细胞72小时后,随着浓度的增加,G2/M期细胞逐渐增多,分别为(29.84±6.215)%,(34.58±1.187)%和(70.23±6.325)%,与对照组(7.79±0.570)%相比,后两组差异有统计学意义(P<0.05).C6细胞中Bcl-2蛋白阳性表达率随药物剂量的增大而减小.结论:PAB可抑制大鼠神经胶质瘤C6细胞增殖,阻滞细胞周期于G2/M期、下调Bcl-2表达为其可能的作用机制.     

重组人黄体生成素在体外受精-胚胎移植促排卵治疗中的应用

Objective To evaluate application of recombinant human luteinizing hormone (r-hLH)used in ovarian stimulation of assisted reproductive technique and impact on outcome of pregnancy. Methods From Apr. To Jul. 2009, 123 patients with low LH level ( < 1 U/L) at day 3 of menstruation and downregulation of pituitary function undergoing in vitro fertilization-embryo transfer (IVF-ET) in Reproductive Medical Center, Provincial Hospital Affiliated to Shandong University were enrolled in this study, whom were classified into 66 cases treated by r-hLH in r-hLH group and 57 cases without r-hLH treatment in non-r-hLH group. In the mean time, 145 patients with normal level of serum LH ( 1-2 U/L) not given by r-hLH treatment and undergoing IVF-ET were matched as control group. Total amount of gonadotropin, estradiol levels and LH levels on the administration of human chorionic gonadotropin ( hCG), number of oocytes retrieved, number of 2PN zygotes, rate of high quality embryos, the rates of implantation and clinical pregnancy were compared among these three groups. Results The level of serum LH on the day of hCG administration were ( 1.59 ± 0.77 ) U/L in r-hLH group, (0.54 ± 0.25 ) U/L in non-r-hLH group and (2.39 ± 1.01 ) U/L in control group, which reached tatistical difference between every two groups (P < 0.05). The rates of high quality embryo were 59.36％ in r-hLH group, 57.79％ in non-r-hLH group,which were significantly lower than 65.94％ in control group, respectively (P < 0. 05 ). The rates of 2PN were 67.62％ in r-hLH group and 68. 32％ in control group, which were significantly higher than 62. 84％ in non-r-hLH group, respectively ( P < 0.05 ). The rates of implantation of 29.77％ in r-hLH group were significantly higher than 18.26％ in non-r-hLH group ( P < 0.05 ). The total amount of gonadotropin,estradiol level on the day of hCG administration, the number of oocytes retrieved, and clinical pregnancy rate were not significantly different among those three groups ( P > 0.05 ). Conclusion The administration of recombinant human uteinizing hormone in patients who are profoundly suppressed after down-regulation with long protocol can get more quality embryos, the higher rates of 2PN and implantation.

怎样理解月经过少?

月经过少有哪些误区 1.我曾经说过,人体的结构非常复杂.把它形容成一架结构复杂的机器并不恰当.机器再复杂,都有一定的参数质控,越是复杂,参数越精准.而人体却不然,人体的结构,各个系统的状态,大部分只是一个正常范围.月经也是如此.偶尔月经量的多少,时间长短改变,并不一定是病理情况.如没有导致特别的不适,可以暂且观察1～2个周期.
