1.Pregnancy in renal transplant recipient: A case report and review
Journal of Peking University(Health Sciences) 2009;41(6):710-711
SUMMARY In recent years, successful pregnancies in renal transplant women have been reported worldwide. However, pregnancy in renal trasplant recipient is relatively rare in China. This paper reported a case of pregnancy 2 years post renal transplant. At the end of 28 weeks' gestation she had abnormal liver and renal function complicated with severe preeclampsia. Literatures were reviewed on considerations about pregnancy in renal transplant women. Maternal and neonatal outcomes can be improved by intensive care during pregnancy, proper immunosupression and timely termination of pregnancy.
2.Prevention of recurrence and metastasis of gastrointestinal stromal tumor
Cancer Research and Clinic 2006;0(08):-
With the progress of gastrointestinal stromal tumor(GIST), to prevent GIST's recurrence and metastasis is still a hot topic. The pre-operative pathological diagnosis of GIST is difficult to be made, and the biopsy has the chance to cause metastasis. Standard operative procedure is the key point to prevent GIST's recurrence and metastasis, which includes en-bloc resection, enough margin and so on. For the recurrence/metastasis GIST, the reoperation can be performed, but the effective therapy is to use the molecular targeted drug:imatinib.
3.Surgical treatment in gastrointestinal stromal tumors
Cancer Research and Clinic 2006;0(08):-
The treatment of gastrointestinal stromal tumors (GIST) has been revolutionized by the molecular targeted therapy, but we still emphasize the importance of how to use surgical principle and skill to treat GIST. In this review, we describe the experience in the treatment of GIST located in esophagus, gastrointestinalinal tract and colorectum. During operation, the surgeon shouldi resect the tumor completely. If the tumor can not to be resected completely, treatment should be managed by imatinib mesylate(Gleevec). Because GISTs seldom appear lymph metastases, it is not necessary to perform lymph node dissection.

Objective To investigate the causes and mechanism of preterm birth through analysis of the relationship between histological chorioamnionitis (HCA) in placental tissue and preterm birth.Methods Totally,327 preterm birth cases with report of placental pathologic examination were retrospectively collected from those women who delivered from December 1,2009 to December 1,2012 in Peking University First Hospital.According to the etiology of preterm birth,three groups were assigned:iatrogenic group (n=106),spontaneous contraction group (n=56) and premature rupture of membranes (PROM) group (n=165).According to the gestational age at delivery,three subgroups were further divided:early-preterm group (≥ 28-< 32 weeks),mid-preterm group(≥ 32-< 34 weeks) and late-preterm group (≥ 34-< 37 weeks).HCA was confirmed when ≥ 5 neutrophil infiltration identified on the chorionic plate and amniotic membrane under high power light microscope after HE staining.The relationship between HCA and the different types of preterm birth and the different delivery gestational age were analyzed.Besides,the consistency between clinical chorioamnionitis and HCA was also analyzed.Chi-square test was applied for statistics.Results The incidence of HCA in the spontaneous contraction group was significantly higher than in the iatrogenic group and PROM group [66.1% (37/56) vs 25.5% (27/106) and 33.3% (55/165),x2=25.27 and 18.44,both P < 0.01],but no significant difference was found between the latter two groups (P > 0.05).Among the three subgroups,the early-,midand late-preterm subgroup,the incidence of HCA in the iatrogenic group was 24.0% (6/25),33.3% (8/24) and 22.8% (13/57) (P > 0.05),and 13/17,5/7 and 59.4% (19/32) in the spontaneous contraction group (P > 0.05).However,significantly higher incidence of HCA was shown in the early-preterm subgroup than in the mid-and late-preterm subgroup [70.0% (20/29) vs 41.2% (14/34) and 20.6% (21/102),X2=4.87 and 24.58,both P < 0.05] in the PROM group.Among the subjects in PROM group,those with the latency ≥ 72 h after the rupture of membranes had a higher incidence of HCA than those with the latency less than 72 h [68.6% (24/35) vs 23.8% (31/130),x2=24.82,P < 0.01].For all 327 cases in this study,the incidence of clinical chorioamnionitis was 15.9% (52/327),among which 31 cases [59.6% (31/52)] were diagnosed as HCA.Conclusions The occurrence of HCA is closely associated with spontaneous contraction preterm.Some iatrogenic preterm birth might cause HCA.The earlier the preterm birth and the longer the latency after PROM,the higher the incidence of HCA.Differential diagnosis is necessary as the inconsistency between clinical chorioamnionitis and HCA.

Objectives To determine the predictive effect of the transvaginal ultrasonographic cervical measurement in induction of labor among the nulliparous. Methods This prospective observational study recruited women with singleton gestation scheduled for induction of labor at ≥37 weeks. All the pregnancy women were nulliparous. Transvaginal ultrasonographic cervical measurement was performed and Bishop score was detemined, each by operators masked to the other measurement. Data were collected on parity, gestational age, mode of delivery, induction agent, induction onset of labor interval, Bishop score and cervical measurement. Results A total 121 women were included. A stepwise regression model identified cervical length was the best linear predictor of induction to onset of labor interval. ( r=0.67, P

Objective To analyze the oral glucose tolerance test (OGTT) curve characteristics in Chinese women with gestational diabetes mellitus (GDM) or gestational impaired glucose test (GIGT) and to evaluate whether omission of the third-hour plasma glucose measurement of the OGTT could alter the sensitivity of the diagnosis on GDM,and whether there is a close relationship between plasma glucose values of 50 g glucose challenge test (50 g GCT) or OGTT and insulin therapy. Methods A retrospective analysis on medical records of 647 cases with GDM from January 1,1989 to December 31,2002 and 233 cases with GIGT were performed. Among 647 cases of GDM,535 were diagnosed by 75g OGTT. All OGTT (535 with GDM and 233 with GIGT) results were evaluated. Results There were 112 cases of GDM diagnosed by elevated fasting plasma glucose without OGTT performed. Of 535 cases of GDM diagnosed by OGTT,49.2% (263/535) women were with fasting plasma glucose value ≥5.8 mmol/L;90.1% (482/535) women with 1hr plasma glucose values ≥ 10. 6 mmol/L;64.7% (359/535) were with 2 hr plasma glucose levels ≥9.2 mmol/L. There were only 114 cases (21.3%) with abnormal 3 hr plasma glucose levels among 535 women with OGTT,and when 3 hr plasma glucose reached cutoff value,49.1% the other three values of OGTT were abnormal and 34.2% with the other two values of OGTT. Among 233 women with GIGT,only 4 cases with the abnormal 3 hr plasma glucose. We also investigate use of the glucose values for the first 2 hours of OGTT only missed 19 cases of GDM,still discriminated 516 cases. Omission of the third -hour glucose tolerance test value only resulted in failure to diagnose 2.9%(19/647) of GDM cases and 1.72%(4/233) of GIGT cases in Chinese women. Plasma glucose levels ≥11.2 mmol/L following 50 GCT were highly associated with GDM necessitating insulin therapy (75.4%). An elevated fasting plasma glucose level was also associated with insulin therapy (59.7%).Conclusion Omission of the third -hour glucose tolerance test value still yielded a higher sensitivity of 97.1%(628/647) of GDM cases and 98.2%(229/233) of GIGT cases in Chinese women. It is practicable to omit 3-hour post -glucose ingestion value of the OGTT in Chinese women. Plasma glucose levels ≥11.2mmol/L following 50g GCT indicated 75.4% cases of GDM necessitating insulin therapy.

Objective To investigate clinical presentation, diagnosis,gestational outcome and treatment of Eisenmenger’s syndrome during pregnancy. Methods Two patients with Eisenmenger’s syndrome during pregnancy were reported retrospectively. Results The first case was admitted in labor at 34 weeks and 4 days in pregnancy,She had dysphoria,tachypnea and dyspnea right after vaginal delivery and died immediately The diagnosis of pulmonary embolism was highly suspected clinically. The second case was admitted because of fetal growth restriction Cesarean section was performed after cyanosis worsened at 35 weeks and 4 days She was discharged from the hospital two weeks after delivery. Conclusion Eisenmenger’s syndrome during pregnancy was associated with extremely poor maternal and fetal outcome Pregnancy is contraindicated in such patients Contraception is necessary after marriage Pregnancy should be terminated as early as possible in such women. In cases who intends to continue the pregnancy,closely observation must be provided to ensure the safety for both mother and the fetus.
