补锌对孕妇锌营养状况及其胎儿生长发育的影响

目的：探讨补锌对孕妇锌营养状况及胎儿生长发育的影响。方法：48例孕妇于孕中期每天补充锌元素20mg，测定孕中、晚期血清锌浓度；新生儿出生时的血清锌浓度及新生儿生长发育指标，并与53例不补锌的孕妇及其新生儿作对照。结果：补锌组孕妇孕晚期血清锌浓度明显高于对照组（P＜0．01），两组中孕中期血清锌浓度＜10．71μmol/L者，补锌组孕妇的新生儿出生体重明显高于非补锌组孕妇的新生儿（P＜0．05）。结论：补锌可提高孕妇孕中、晚期的血清锌浓度，对于孕中期血清锌浓度＜10．71μmol/L中，补锌可能有助于增加其新生儿的出生体重。

The Clinical and Experimental Research on Billings Ovulation Method During Breastfeeding

Objective The effectiveness and acceptability of Billings Ovulation Method (BOM) during breastfeeding were studied. At the same time, the monitoring indexes of fertility return were studied.Methods It was a clinical comparative study of BOM and IUD containing copper (200mm 2). The annual rate of pregnancy, discontinuation rate and continuation rate in the two groups was determined. The serum prolactin and estradiol in 90 breastfeeding mothers and urine estrogen and pregnanediol in different feeding mothers were measured.Results There were 219 subjects in the BOM group and 200 in the IUD group. The pregnancy rate in this two groups was 1. 43% and 1. 54% respectively. The rates of discontinuation and continuation in the IUD group were:8. 87% and 91. 35% as well as in the BOM group were 8. 53% and 90. 17% respectively. Neither result was statistically significant (P>0. 05). The experimtal research showed that menses return was well estimated by 0. 35 ratio of serum prolactin vs. estrodiol. Sensitivity and     

异丙酚、芬太尼、氯胺酮分别用于无痛人工流产术效果观察

目的:探讨异丙酚、芬太尼、氯胺酮分别用于无痛人工流产手术效果观察。方法:将400例早孕要求人工流产的孕妇随机分为异丙酚组、芬太尼组、氯胺酮组和未用药组,每组各100例,观察用药3组镇痛效果,出血量,人工流产综合征,术时血压、心率、呼吸、血氧饱和度情况以及副作用,并与对照组相比。结果:异丙酚组、芬太尼组、氯胺酮组与对照组相比,3组镇痛效果明显(P<0.01),降低人工流产综合征的发生(P<0.01),且未增加术中出血量(P>0.05)。结论:异丙酚、芬太尼、氯胺酮用于无痛人工流产术效果均较理想。     

比林斯法在哺乳期应用的实验和临床研究

目的 :观察比林斯生育调节法 (BOM)在哺乳期避免妊娠的可行性和有效性 ,寻找监测哺乳期生育力恢复的指标。方法 :对比研究比林斯法和 IUD法在 1 2个月中的意外妊娠率、停用率和续用率。测定血生乳素、雌二醇用以估计月经恢复 ;检测尿雌激素和孕二醇 ,确定第 2次月经前是否排卵。结果 :哺乳期比林斯法和 IUD法两组妇女分别观察了 2 1 9例和 2 0 0例。妊娠率、停用率和续用率分别为 1 .43 %、1 .5 4 %,8.5 3 %、8.87%和 90 .1 7%、91 .3 5 %,两组间无统计学差异 (P>0 .0 5 )。同期进行的 90例和 2 75次血生乳素、雌二醇的测定发现 ,二者比例以 0 .3 5作为月经恢复的指标。6 1例尿雌激素和孕二醇测定表明 ,宫颈粘液类型与激素水平吻合外 ;混合喂养妇女第 2次月经前排卵发生率为 47.0 5 %。结论 :(1 ) BOM用于哺乳期避孕的效率如同 IUD法 ,也能被哺乳期妇女接受。 (2 )血生乳素和雌二醇测定可估计哺乳期妇女月经恢复 ,方法简单 ,可应用于临床。 (3 )混合喂养有延迟哺乳期生育的作用。
