观察受体鼠妊娠和胚胎着床情况,并检测胚胎移植时小鼠子宫内膜中白血病抑制因子(Lif)表达水平,探讨超排卵对小鼠胚胎着床潜能的影响。方法:建立超排周期胚胎和自然周期胚胎移植小鼠模型,比较妊娠率、胚胎着床率的差异及其与Lif蛋白的表达水平之间的关系。结果:超排卵周期受体组的妊娠率(20.00%)和胚胎着床率(8.33%)显著低于自然周期组的妊娠率(55.00%)和胚胎着床率(35.00%)(P<0.05)。自然周期胚胎和超排周期胚胎受体组内膜中Lif蛋白的表达水平相似(P>0.05),妊娠受体组Lif蛋白的表达水平显著高于未孕受体组(P<0.05),但单胎妊娠和多胎妊娠受体组内膜中Lif蛋白的表达水平相似(P>0.05)。结论:超排卵可能降低胚胎的着床潜能,Lif蛋白的表达水平与胚胎着床有关,但与着床胚胎的数目无比例关系。
摘要:目的: 探讨二维及彩色多普勒超声对妊娠合并卵巢扭转的诊断价值。 方法 :对11例经手术及病理证实的妊娠合并单纯卵巢扭转,进行二维及彩色多普勒和能量多普勒超声图像分析。 结果 :11例患侧卵巢在二维图像中均有不同程度的肿大,超声压痛征均呈阳性反应;其中7例有明显的位置改变,5例有不同程度的盆腔积液;彩色多普勒和能量多普勒显示患侧卵巢内部均无明显血流信号。 结论 :妊娠期卵巢扭转有典型超声图象特征,可为临床提供较可靠的诊断依据。Abstract: Objective: To evaluate the diagnostic value of two dimension ultrasound (2DUS), color Doppler flow imaging (CDFI) and power Doppler imaging (PDI) for ovarian torsion during the pregnant period.〖WTHZ〗Methods : Using the techniques of 2DUS, CDFI and PDI to analyze sonographic features of 11 ovarian torsion cases which were dominated by operation and pathology.〖WTHZ〗Results : The tumescent sick ovaries were detected in all case with ovaries torsion by 2DUS. The patient felt pain when their sick ovaries were pressed. The position of seven sick ovaries was changed. The pelvic effusion was detected in five cases. The blood flow signal was not demonstrated in all sick ovaries by CDFI and DPI.〖WTHZ〗Conclusion : The ultrasonic imaging characteristics are reliable to diagnose ovarian torsion during the pregnant period.
The authors studied retrospectively clinical data of seventy cases with breast cancer during pregnancy and lactation.They were treated and diagnosed by operation and pathology.Primary factors influencing prognosis were analyzed.It was demonstrated that 5year survival rate of the patients were significantly influenced by clinical stage , month of pregnancy and lactation, time of symptoms, type of operation, type of pathology, histological grade of malignancy, recurrence and metastasis, and estrogen receptor status (P<0.05).Age and termination of pregnancy had no beneficial effect on survival (P>0.05).The prognosis of pregnant and lactating breast cancer was poorer than ordinary breast cancer.Their 5year survival rate were 55.7% and 74.3%, respectively. After they were matched for stage and for age, no difference in survival was found.Early diagnosis and radical operation combined with radiotherapy, chemotherapy and hormonal therapy have better prognosis.The method can shorten time of treatment and improve survival rate.Termination of pregnancy has not been shown to improve survival and shall not be advised routinely.Future pregnancy may be detrimental and shall be discouraged.
目的:了解正常妊娠妇女血清中常用肝功能指标测定结果及变化。方法:分别在早孕(孕10~14周)、中孕(孕20~24周)、晚孕(孕30~34周)及产后(产后12周)四个时期序贯性测定120例正常妊娠妇女血清谷丙转氨酶(ALT)、谷草转氨酶(AST)、γ谷氨酰转移酶(GGT)、乳酸脱氢酶(LDH)、总胆红素(TBIL)、直接胆红素(DBIL)、总蛋白(TP)、白蛋白(ALB)、前白蛋白(PA)的水平并进行比较。结果:ALT、AST在早、中、晚孕及产后各期相对于正常对照均升高(P<0.01);TBIL和DBIL在早、中、晚孕均降低(P<0.01);TP、ALB随孕期增加逐渐下降,产后回升,到产后12周上升到正常水平(早、中、晚孕P<0.01,产后P>0.05);GGT在孕期中逐渐升高,于晚孕期达最高峰(P<0.01),产后稍有下降;LDH在孕早中期无明显变化(P>0.05),孕晚期上升,到产后12周仍呈一上升趋势(P<0.01);PA在孕早期低于正常对照(P<0.01),后随孕期上升,到中孕期后上升到正常(P>0.05)。结论:本次实验观察到在妊娠期肝功指标ALT、AST、GGT、LDH升高,可能因为孕妇肝脏负荷增加、基础代谢和能量消耗增多、甾体激素水平增高引起。胆红素代谢指标及营养性指标TBIL、DBIL、TP、ALB、PA降低,可能是妊娠期血浆稀释引起。临床诊断妊娠合并肝功能损害时应考虑上述变化。
Objective To assess the efficacy and safety of S-adenosyl-l-methionine (SAMe) for outcome improvement of intrahepatic cholestasis of pregnancy. Methods Randomized controlled trials (RCT) and quasi-randomized controlled trials were identified from MEDLINE (1983 to 2003), The Cochrane Library (Issue 4,2003), EMBASE (1980 to 2003), China Hospital Digital Library (CHDL) and Wanfang data (1994 to 2003). We also handsearched the relative references. Two researchers evaluated the quality of the trials and extracted the data independently. RevMan software 4.2 was used for meta-analysis. Results Eight studies involving 424 pregnant women were included. The following data were the results of meta-analysis of SAMe for improvements: ① Reducing cesarean-section ratio: no significant difference was seen between SAMe and placebo groups with OR 1.00, 95%CI 0.23 to 4.33 and P= 1.00; significant differences were seen SAMe versus dexamethasone and SAMe versus Dianglining with OR 0.44, 95%CI 0.23 to 0.85 and P=0.01; OR 0.28 95%CI 0.10 to 0.75 and P=0.01 respectively。② Prolonging the period of pregnancy: SAMe had no significant difference compared with placebo groups with WMD=0.70, 95%CI -0.69 to 2.10, P=0.32. SAMe was more effective than dexamethasone, Ganyinling and Qianglining on prolonging the period of pregnancy with WMD=1.10,95%CI 0.46 to 1.74, P=0.000 07; WMD=2.50,95%CI 1.86 to 3.14, P≤0.000 01; WMD=2.20,95%CI 1.61 to 2.79, P≤0.000 01 respectively;③ Increasing the weight of the newborn: meta-analysis showed that SAMe group had not significant difference compared with placebo group on increasing the weight of the newborn with WMD=-26.27,95%CI -338.35 to 285.82, P=0.87. Significant differences were seen between SAMe and dexamethasone, SAMe and Ganyiling, SAMe and Qiangling with WMD=386.86,95%CI 134.41 to 603.31, P=0.002; WMD=410.00,95%CI 321.10 to 498.90, P≤0.000 01 respectively. ④ Fetal distress: There was no significant difference compared with dexamethasone and Kuhuang groups on decreasing the fetal distress with OR=0.47, 95%CI 0.14 to 1.16, P=0.23; OR=0.44, 95%CI 0.10 to 1.97, P=0.29 respectively; ⑤ Decreasing pollution of amniotic fluid: no significant differences were seen in SAMe versus dexamethasone, SAMe versus ursoddeoxycholic and SAMe versus Kuhuang with OR=0.46, 95%CI 0.21 to 1.02, P=0.06; OR=0.68, 95%CI 0.20 to 2.31, P=0.53; OR=0.82 95%CI 0.24 to 2.81,P=0.75 recpectively. ⑥ Newborn stifile: SAMe group had no significant difference compared with dexamethasone and Kuhuang groups on decreasing the Newborn stifile with OR=0.19, 95%CI 0.01 to 4.06, P=0.29; OR=0.31, 95%CI 0.08 to 1.13, P=0.08 respectively. Compared with Qianglining group, SAMe group had better effect on reducing ratio of newborn stifile with OR=0.09, 95%CI 0.02 to 0.42, P=0.002. ⑦ Improving Apgar scores: no significant differences were seen between SAMe and placebo, dexamethasone and ursoddeoxycholic with OR=0.25, 95%CI 0.02 to 3.04, P=0.28; OR=2.09, 95%CI 0.70 to 6.27, P=0.19; OR=1.22, 95%CI 0.35 to 4.19, P=0.75 respectively. Six RCTs mentioned the side effects of S-adenosy-l-methionine, only one RCT reported mild gastrointestinal irritation. Conclusions SAMe is partly effective on improving the pregnancy outcomes of intrahepatic choletasis of pregnancy, such as reducting cesarean-section ratio, prolonging the period of pregnancy and increasing the weight of the newborn. The specified efficacy and safety of SAMe require rigorously designed, randomized, double-blind and placebo-controlled trials to offer evidence.
