重庆市主城区早孕期妇女叶酸与出生缺陷预防认知调查

目的了解旱孕期妇女对叶酸、出生缺陷认知度，促进早孕期妇女对出生缺陷预防的认识。方法采用问卷形式对重庆市主城区147名正常早孕期妇女进行调查，随机抽取96名参加血清叶酸值测定。结果参与调查的早孕期妇女，叶酸知晓率为88．4％；68人（46．3％）能够正确选择“叶酸的功能”选项；123人（83．7％）知道胚胎发育早期体内叶酸缺乏可能会影响胎儿神经系统的发育；21人（14．3％）选择会在孕期全程服用叶酸，有24人（16．3％）一直未服用。16人（10．0％）接触了射线、噪声、化学制剂等有害环境因素；9人（6．1％）在孕期服用了药物；9人（6．1％）在饮食或生活习惯上对胎儿发育不利。神经管畸形认知度调查结果显示，59人（40．1％）清楚神经管畸形的类型包括无脑儿、脑积水和脊柱裂；74人（52．1％）认为怀孕时体内缺乏叶酸是神经管畸形发生的可能原因。96名参加血清叶酸值测定结果显示，无叶酸缺乏者，其统计均值为（26．34±9．81）ng／mL。结论早孕期妇女对出生缺陷预防的认识有待进一步提高。     

院内发生急性心肌梗死的临床探讨

急性心肌梗死（AMI）系常见心血管疾病，虽多年来在诊治上有进展，死亡率已下降至10％左右，但对中老年生命威胁仍较大。在工作中，作发现有部分AMI是在住院过程中发生，为提高防治水平，特将我院1994年10月～2005年4月住院发生的16例AMI分析如下。[第一段]     

The correlation between TNF-α, IL-6 in cervical mucous during follicular development and ovulation stimulation in different protocols

Objective To investigate the correlation between TNF-α and IL-6 levels in cervical mucous during follicular development and ovulation stimulation in different protocols.Methods 36 infertile women were set up as experimental groups,divided into CC, HMG, IVF-ET group,each group consisted of 12 infertile women and 15 women with normal menstrual cycles were choiced as control group.Cervical mucous during follicular phase, luteal phase and ovulation phase were collected.TNF-α, IL-6 levels in cervical mucous were measured by radioimmunology assay (RIA).Follicular development were monitored by transvaginal ultrasonagraphy.Results (1) TNF-α levels in cervical mucous of experimental groups and control group were periodically various among the reproductive cycle.It increased during follicular phase, reached to peak during ovulation phase, and decreased during luteal phase (P＜0.05).IL-6 levels had no obvious periodical changes.(2) Compared with CC and control group, levels of TNF-α,IL-6 in HMG and IVF-ET group were significantly higher (P＜0.05).(3) Levels of TNF-α and IL-6 in cervical mucous were positively correlated with the dominant follicle diameter (r=0.261, r=0.192 respectively,P＜0.05).(4) TNF-α and IL-6 showed positive correlation in the reproductive cycle (r=0.782,P＜0.05).Conclusions (1) TNF-α level shows a cyclic change in the reproductive cycle and peaks during ovulation,whereas IL-6 level does not.(2) TNF-α and IL-6 may play a certain role in the process of follicular development and ovulation.(3)The levels of TNF-α and IL-6 are up-regulated by gonadotrophic hormone.(4) TNF-α and IL-6 may have coordination properties and participate in the same biological effects.     

Comparison of clinical outcomes of frozen-thawed blastocysts transfer in natural and hormonally controlled cycles

Objectives:To assess the clinical outcomes of frozen-thawed blastocysts transfer in natural and hormonally controlled cycles.Methods:A retrospective analysis of natural and hormonally controlled cycle for 246 frozen-thawed blastocyst transfer cycles,the clinical pregnancy rate,implantation rate,early abortion rate were compared.Results:Of the 192 hormonally controlled cycles,the cancel rate,clinical pregnancy rate per ET,implantation rate and abortion rate were 7.3%(14/192),53.9%(96/178),38.8%(131/338)and 11.5%(11/96)respectively,whereas in 54 natural cycles,these rates were 16.7%(9/54),68.9%(31/45),52.9%(45/85)and 16.1%(5/31)respectively.There was no significant difference between the two groups with regard to the clinical pregnancy and abortion rate per ET,but the cancel rate and implantation rate were higher in natural cycles.However,the pregnancy and implantation rates of patients without PCOS in hormonal control cycles(57.2%,40.9%)were similar with those in natural cycles(P>0.05).Conclusion:These findings suggested that both hormonally controlled and natural cycles had similar pregnancy outcomes in frozen-thawed blastocysts transfer.
