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.

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.

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 awareness of knowledge about HPV infections and the willingness to HPV vaccination among male university students in Tongzhou District, Beijing Municipality, so as to provide insights into the formulation of the HPV vaccination strategy among males. Methods: A total of 997 male university students in Tongzhou District were selected as the study subjects using a multi-stage stratified cluster random sampling method, and a self-designed questionnaire was used to investigate the awareness of HPV infections and HPV vaccine, and willingness to HPV vaccination. In addition, the factors affecting the willingness to HPV vaccination were identified. Results: A total of 935 subjects were enrolled, with a mean age of (19.08±1.38) years, and there were 570 subjects with a Beijing household registration (60.96%). Among the 313 male university students that had heard of HPV, the awareness of HPV and HPV-related diseases was 59.42%, and among the 300 male university students that had heard of HPV vaccines, the awareness of HPV vaccines was 75.33%. The willingness to HPV vaccination was 38.50%, and the willingness was high among male university students with a non-Beijing household registration ( χ2=3.971, P=0.046 ), high household annual income ( χ2trend=6.219, P=0.013 ), short distance to vaccination clinics ( χ2=19.238, P<0.001 ), having heard of HPV ( χ2=11.188, P=0.001 ), having heard of HPV vaccine ( χ2=14.548, P<0.001 ), awareness of HPV and related diseases ( χ2=16.855, P<0.001 ) and awareness of HPV vaccine ( χ2=19.299, P<0.001 ). Conclusions The awareness of HPV and HPV vaccines and the willingness to HPV vaccination are low among male university students in Tongzhou District. Improving the correct recognition of HPV and HPV vaccines and the access to vaccination services are helpful to improve the willingness to HPV vaccination among male university students.

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.
