高龄初产妊高征孕妇过氧化反应的研究

目的：探讨高龄初产妊高征孕妇体内过氧化反应。方法：测定正常初产妇、妊高征孕妇妊娠晚期母血过氧化脂质（LPO）、超氧化物歧化酶（DOD）的含量。结果：1．高龄初产妇母血LPO较非高龄初产妇明显升高，SOD明显下降，P＜0．05。孕妇年龄与母血LPO呈明显正相关，与SOD呈明显负相关，P均＜0．05。2．妊高征孕妇LPO较正常孕妇显著增高，SOD显著下降，P＜0．05，并随病情加重LPO水平升高、SOD水平下降更为显著，P＜0．05。3．高龄初产妊高征孕妇母血LPO含量较非高龄初产妊高征孕妇明显增高，P＜0．05，而SOD则无显著变化，P＞0．05。4.妊高征孕妇胎儿宫内生长发育迟缓（IUGR）发生率较正常孕妇显著升高，P＜0．025，各组脐血清LPO、SOD含量无显著差异，P＜0．05。结论：高龄初产妊高征孕妇体内过氧化作用明显增强，LPO水平的升高可能为高龄初产妇妊高征发生率及IUGR发生率增加的原因之一。     

Nephrotic syndrome in a mother and her infant: relationship with cytomegalovirus infection

This case report describes infantile nephrotic syndrome (NS) in a baby girl with a clinically severe cytomegalovirus (CMV) infection. Culture of the baby's urine was positive for CMV and IgM anti-CMV antibodies were detected. After an unsuccessful course of corticosteroids, gancyclovir treatment was started and a remission of cutaneous, pulmonary, and renal symptoms was achieved. As the mother also developed NS at the end of pregnancy, a common etiology could be postulated, although there were no signs of recent CMV infection in the mother, only anti-CMV IgG. The relationship between CMV infection and glomerular disease is still unclear: NS may represent another manifestation of CMV disease.     

职业接触氯乙烯对生殖功能影响的调查

对全国１２个城市中１３个聚氯乙烯制造工厂中２７３６名接触氯乙烯的工人及３４４２名对照厂工人，进行了生殖功能的流行病学调查研究，结果表明，接触氯乙烯男、女工人的各项生殖结局指标与对照组比较无显著性差异，但女工氯乙烯接触组妊娠合并症的发生率明显高于对照组，表明氯乙烯对女工的妊娠过程有一定影响，因此积极改善劳动条件，不仅对保护工人健康，而且对保护其子代的正常发育成长也有重要意义。     

可溶性血管内皮生长因子受体-1与妊娠高血压疾病的关系

目的探讨可溶性血管内皮生长因子受体1(sFlt1)与正常妊娠和妊娠高血压疾病的关系。方法23例妊娠高血压孕妇(妊娠期高血压7例、轻度子痫前期3例、重度子痫前期9例、子痫4例)为妊娠高血压疾病组,20例足月妊娠血压正常孕妇作为对照组。应用半定量逆转录聚合酶链反应(RTPCR)技术检测两组孕妇分娩后胎盘组织中sFlt1的表达强度。结果妊娠高血压疾病组sFlt1mRNA1.45±1.47,与对照组1.04±0.69比较,差异无显著性(P>0.05)。子痫组(2.99±2.47)明显高于对照组(P<0.01)。结论sFlt1是维持正常妊娠所必需的因子。它表达水平的高低与妊娠高血压的发病有关,在子痫患者中表达明显增高。     

妊娠期妇女外阴阴道念珠菌病的病原学和治疗研究

目的 调查孕妇外阴阴道念珠菌病(vulvovaginal candidiasis，VVC)的发病率，对检出的VVC进行病原学和治疗研究。方法 连续对产科门诊1000例孕妇进行VVC发病情况调查。对分离的念珠菌进行体外抗真菌药物敏感试验。对66例VVC患者应用咪康唑栓治疗，400mg／d，6d为一疗程。结果 孕妇VVC的发病率为12．7％(127／1000)。37．4％(374／1000)的孕妇以往有VVC病史，0．6％的孕妇为复发性VVc。127例VVC中，白念珠菌、光滑念珠菌、热带念珠菌和克柔念珠菌分别占87．1％、9．9％、1．5％和1．5％。有4例患者同时感染2种念珠菌。114株白念珠菌对咪康唑、克霉唑、氟康唑、伊曲康唑、制霉菌素耐药率依次为10．5％、2．6％、6．1％、7．9％和0。13株光滑念珠菌对咪康唑和制霉菌素均敏感，对克霉唑、伊曲康唑和氟康唑均敏感或剂量依赖敏感。应用咪康唑栓治疗的患者在治疗完成后1～2周及4～6周的病原学治愈率分别为84．8％和80．3％。结论 VVC是孕妇的常见病，白念珠菌仍然是主要致病菌，其次为光滑念珠菌。常用抗真菌药物对引起VVC的念珠菌存在不同程度的耐药率，应用咪康唑栓治疗孕妇VVC效果满意。     

Significance of Anticardiolipin Antibodies on Short and Long Term Allograft Survival and Function following Kidney Transplantation

The significance of anticardiolipin antibodies (ACAs) prior to renal transplantation is unclear. We studied a cohort of 337 patients who underwent renal transplantation from 1996 to 2001. Follow-up continued until allograft loss, patient death or 31 December 2002. The primary outcome was a composite endpoint of death-censored allograft loss or a 25% reduction in estimated glomerular filtration rate (GFR) from 1-month post-transplant. Secondary outcomes were allograft loss, a 25% reduction in GFR, acute rejection and creatinine at 1 year. IgG and IgM ACA titers were positive (> or =15) in 18.1% of recipients. There were no significant differences at baseline between recipients, except coumadin therapy in those with positive ACA titers (20% vs. 7.4%). Post-transplant, there was no increase in the primary outcome in ACA-positive patients, even after adjustment for anticoagulation with coumadin (HR = 1.42 [0.68, 2.96]). There was no difference in secondary outcomes between those with or without positive titers. Two of five patients with very high titers (>50) who were not anticoagulated had early graft loss. A positive ACA titer prior to kidney transplantation was not associated with inferior renal outcomes after transplantation, although more research is required to address the prognostic significance of very high ACA titers.     

Foetal radiation dose in radiotherapy for breast cancer

Management of breast cancer during pregnancy is complicated by the high risks of abortion and foetal malformation from the use of radio therapy and chemotherapy. A case of breast cancer during pregnancy, treated with radiotherapy, and the estimated foetal dose is reported.     

Transurethral resection of a bladder tumor in pregnancy: A report of 2 cases

Carcinoma of the urinary bladder presenting during pregnancy is rare. We report two such cases presenting with gross hematuria, both of which were managed by transurethral electroresection of the tumor; there was no adverse effect on the pregnancies. Transurethral resection thus appears to be the procedure of choice in the management of this condition, and carries minimal morbidity even when performed during pregnancy. EDITORIAL COMMENT: As these authors point out, bladder tumors are rare in pregnancy and frequently present as gross hematuria that is mistaken for vaginal bleeding due to the pregnancy. Ultrasound is very helpful in distinguishing the causes of bleeding, and will show the bladder filled with clots and frequently the tumor as well. Standard transurethral resection is effective when performed during pregnancy, bearing in mind the need to heed to the anesthetic risks inherent in any operative procedure during pregnancy.     

What should nurse teachers be doing? A preliminary study

There is little doubt that the role of the nurse teacher is complex and multifaceted in nature. The apparently conflicting demands of NHS trusts and education in the United Kingdom, at the time of integration of nurse education into the higher education sector, further complicates the role. This recognition underlines the need to capture and measure key aspects of nurse teacher function in order to maximize educational gain. Using a comprehensive literature review, focus group discussions and a small number of individual semi-structured interviews, this preliminary study explored the issue of teacher workload, from the perspective of the principal stakeholders in nurse and higher education. Competing research and clinical practice objectives for nurse teachers are identified against a background of changing health care provision, reduced availability of placements and an increased need for evidence-based practice.     

上海市闵行区流动人口中的孕产妇保健状况

通过对上海市闵行区580名外来孕产妇及580名作为对照的本地孕产妇的孕产期保健现况调查分析,表明外来孕产妇缺乏必要的孕产期保健措施,有47.6％的外来孕产妇从未做产前检查,产后保健则完全没有,并由此而造成外来产妇在急产、死产、甚至孕产妇死亡等方面令人忧虑的现状。为适应和促进当前经济发展的新形势,改善流动人口的孕产妇保健状况,应对流动人口中孕产妇保健状况深入研究,并采取相应的措施。
