Oral mifepristone 600 mg and vaginal gemeprost for mid-trimester induction of abortion: An open multicenter study

This open multicenter study was performed in 20 hospital gynecological units in the UK. The effects of 600 mg oral mifepristone as pretreatment to vaginal prostaglandin induction of second second trimester abortion was studied in 267 women.

The primary efficacy variable was the abortion induction interval, defined as the time taken to expel the fetus from the time of administration of the first prostaglandin pessary. Induction was commenced 36 to 48 hours following mifepristone intake.

The mean abortion induction interval was 7 h. A total of 81.9% of women aborted within 12 h. There was a significant relationship between abortion induction interval and age of gestation, and a significant inverse relationship between abortion induction interval and parity.

Vomiting, pelvic pain, and nausea were the most frequently reported adverse events. Two patients required transfusion and one patient with a uterine scar from a previous cesarean section suffered a ruptured uterus and hysterotomy.     

1994～2001年广西疾病监测点甲、乙类传染病发病特点分析

目的 通过对广西疾病监测点1994—2001年甲、乙类传染病发病特点进行分析，为广西甲、乙类传染病的防治提供科学的依据和建议。方法 运用Epi Info2000统计软件将监测点1994～2001年甲、乙类传染病报告资料进行整理分析。结果 监测点的报告发病率高于常规疫情，甲、乙类传染病总体发病水平呈下降趋势，农村地区所报病种远多于城市；肠道传染病呈逐年下降，血源及性传播疾病呈上升趋势，肺结核已成为广西高发病种。结论 广西疾病监测工作的建设仍需加强，肠道传染病防治工作不能放松，呼吸道传染病和血源及性传播疾病的控制力度要加强。     

我对子午流注阴阳盛衰转换的认识

阐述了时相与阴阳的关系，阴阳昼夜的盛衰转换与经脉循行、气血流注密切相关；对传统流注说和任督为主的阴阳循环说进行了分析，认为子午流注阴阳盛衰转换在妇科学中有重要意义，子午流注所指出的4个较重要的时期与月经周期中的4期(行经期、经后期、经间排卵期、经前期)相关。重视研究日相阴阳太极钟的变化，将能更加深入地认识月经周期中阴阳消长转化的规律变化，从而推动中医妇科学向前发展。     

Recombinant human erythropoietin in the treatment of cancer-related anaemia

Abstract: The efficacy and safety of recombinant human erythropoietin (rhEPO) were tested when given subcutaneously (s.c.) in an escalating dose of 2000–10,000 units (U) daily in 60 patients with cancer-related anaemia (CRA). A positive response, defined as an increase in haemoglobin more than 2 g/dl and independence of blood transfusions, was observed in 23 of 48 evaluable patients (48%) within a median of 8 wk. In detail, rhEPO corrected anaemia in 11 of 14 patients (79%) with malignant lymphoma, in 8 of 15 patients (53%) with multiple myeloma and in 4 of 10 patients (40%) with a solid tumour. The median dose of rhEPO in successful cases was 5000 U daily. Four patients with agnogenic myeloid metaplasia and 5 with myelodysplastic disorder failed to respond to rhEPO. No patient had any severe side effects. Pretreatment serum erythropoietin levels appeared to be a weak predictor for response to rhEPO treatment. In conclusion, rhEPO seems to be safe and effective in correcting CRA in certain groups of patients.

同济医科大学控烟活动及效果评价

我校自1993年开展控烟工作，1995年9月开始创办无吸烟大学校园，采取了卫生宣教和行政干预等综合措施，并进行了效果评价。高强度干预措施实施前期（1995年3月）和中期（1996年10月）相比，男医学生和男女学生平均吸烟率分别从16.3％和11．4％下降到9．6％和5．94％；男教工和男女教工平均吸烟率分别从28．6％和13．8％下降到13．9％和8．86％。     

Hepatic-pericardio-phrenic collateral (natural shunt) in a patient with Budd-Chiari syndrome

Hepatic venous outflow tract obstruction, Budd-Chiari syndrome (BCS), leads to portal hypertension and to the development of collaterals that bypass the obstruction. Described here is a BCS patient with an unusually large transdiaphragmatic collateral between the left hepatic and left innominate veins, which decompressed the oesophageal varices. This has not been reported earlier in the literature.     

Screening and treatment of bacteriuria in pregnancy and postpartum period

The paper gives an overview of today's knowledge of urinary tract infection in pregnancy and different treatment procedures. Three different studies of urinary tract infection (UTI) in pregnancy and the postpartum period are reported. Urinary screening of 1798 pregnant women showed a cumulative frequency of bacteriuria of 4.8%, recurrent infection in one-fifth of the cases, and pyelonephritis in 0.6%. Chlamydial infection was observed as a cause of dysuria in pregnancy. In the postpartum period bladder bacteriuria was demonstrated in 3.7%. The condition persisted in 27%, while short-course treatment had significant effect.Presented at the Zambon Symposium on Bacteriuria in Pregnancy, International Urogynecological Association Annual Meeting, Riva del Garda, Italy, September 13, 1989.     

Incentives for cooperation in quality improvement among hospitals--the impact of the reimbursement system.

Up to now, few analytical models have studied the incentives for cooperation in quality improvements among hospitals. Only those dealing with reimbursement systems have shown that, from the point of view of individual or competing hospitals, retrospective reimbursement is more likely to encourage quality improvements than prospective financing, while the reverse holds for efficiency improvements. This paper studies the incentives to improve the quality of hospital care, in an analytical model, taking into account the possibility of cooperative agreements, price besides non-price (quality) competition and quality improvements that may simultaneously increase demand, increase or reduce costs and spill over to rival hospitals. In this setting quality improvement efforts rise with the rate of prospective reimbursement, while the impact of the rate of retrospective reimbursement is ambiguous, but likely to be negative for quality improvements that are highly cost-reducting and create large spillovers. Cooperation may lead to more or less quality improvement than non-cooperative conduct, depending on the magnitude of spillovers and the degree of product market competition, relative to the net effect of quality on profits and the share of costs that is reimbursed retrospectively. Finally, the stability of cooperative agreements, supported by grim trigger strategies, is shown to depend upon exactly the opposite interaction between these factors.
