Objectives: To study the treatment outcome of mucoepidermoid carcinoma(MEC).Methods:128 cases of MEC with definite pathologic diagnosis treated in our hospital during the past 15 years were investigated. The relationship between the effects of the therapy and the prognosis was analysed.Result:Treatment with surgical operation only was used in 99 cases,radiotherapy after operation was applied in 26 cases and follow-up was carried out in 76 cases. 5-year survival rate was 90.7%.5 patients who died within 5 years after operation were all with the diagnosis of MEC in clinical stage Ⅳand poor differentiaton.Conclusion:The local extensive excision for the well differentiated MEC,the radiotherapy after operation for poorly differentiated or that of clinical stage Ⅳ,especially in maxilla,may increase 5-year survival rate.Since there were cases of recurrences of MEC 13 years after surgical treatment,long-term follow-up is necessary.

Objective To study the effects of arsenic trioxide ( As2 O3 ) on inhibiting the proliferation of pancreatic carcinoma cell lines. Methods The inhibiting rate of As2O3 and Fluorouracin(5-Fu) ,Gemcitabine(GEM) on pancreatic carcinoma cell lines PC-3 were detected by using CCK-8 assay. Results As compared with 5-Fu、GEM,the inhibiting rate of As2O3 was the highest one( P ＜ 0.01 or P ＜ 0.05). Conclusion As2O3 can inhibit pancreatic carcinoma cell lines PC-3 effectively in vitro. The effects of As2O3 on inhibiting the proliferation of pancreatic carcinoma cell lines was stronger than 5-Fu and GEM. This is possibly due to the extensive and unique anticancer mechanism of As2O3.

Objective To assess the efficency and safety of non-peritoneal drain versus peritoneal drain after appendectomy of severe appendicitis. Methods Randomized controlled trials (RCTs) or quasi-randomize controlled trials(QRCTs) were searched and identified from CNKI (1994 to Oct 2008) ,CBM (1978 to Oct 2008), VIP (1989 to Oct 2008), Wanfang Data (1997 to Oct 2008), MEDI.INE (1966 to Oct 2008), EMBASE (1974 to Oct 2008),The Cochrane Library (issue3, 2008) and SCI (1974 to Oct 2008), and related journals were also scanned. We evaluated the quality of the included studies by Jadad scale and analyzed the data by Cochrane Collaboration' s RevMan 5. 0. Results We included 15 randomized controlled trials or quais-randomized controlled trials (n = 2809). Meta analysis showed that there were statisticly differences between two groups on the incidence of wound infection [OR = 0.43,95%CI (0.29,0.65)], postoperative intestinal adhesion [OR = 0.26,95%CI(0. 18,0.37)]and the duration of hospital stay [WMD = - 0.38,95%CI(- 4.96, - 1.20)], but no difference was found on the incidence of abscesses [OR = 0. 77,95% CI(0. 39, 1. 51)]. Conclusions The current evidences show that contrast with peritoneal drain, the non-peritoneal drain can significantly reduce the incidence of wound infection and intestinal adhesion, and shorten the duration of hosipital stay. Before draw the conclution into clinical practice, further high-quality, large scale, double-blind randomized controlled trials are still needed.

Objective To compare the clinical effect of off-pump coronary artery bypass grafting (eft-pump CABG)and on-pump coronary artery bypass grafting(on-pump CABG).Methods The clinical dates of 152 cases with coronary artery bypass grafting(off-pump CABG group 85 cases,on-pump CABG group 67 cases)were received from June 2005 to December 2008,the preoperative dates,postoperative mortality and the rate of complication were compared between two groups.Results The preoperative dates of two groups were no significant difference(P>0.05);2 cases(2.35%)were died in off-pump CABG group and 13 cases(15.29%)had complications in off-pump CABG group;9 cases(13.43%)were died in on-pump CABG group and 25 cases(37.31%)had complications in on-pump CABG group.The mortality and the rate of complication in off-pump CABG group was significantly less than that in on-pump CABG group.it was significant difference(P<0.01).Conclusion Off-pump CABG is safe therapy of mieosurgieal operation.

OBJECTIVETo introduce and evaluate the technical feasibility and anatomical and functional outcomes of one-stage vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis.

METHODSWe retrospectively reviewed our experiences with 17 patients with Mayer- Rokitansky-Kuster-Hauser syndrome treated with primary surgery from September 2010 to April 2013. All patients underwent vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis. We describe the details of this technique, observe the time of epithelization and evaluate the long- term anatomical, functional, and sexual outcomes.

RESULTSThe time of epithelization was 13 d (range: 12-15 d). At a mean follow-up of 15 months (range: 12-24 months), the mean postoperative dependence on the vaginal stent was 11.7 ± 1.64 months (range: 9-15 months), the mean depth of the neovagina was (9.0 ± 0.94) cm (range: 7-11 cm), the mean circumference was (12.3 ± 1.36) cm (range: 10.0-14.5 cm) and the mean volume was (105 ± 10) ml (range 85-120 ml). The mean female sexual function index score of the 12 sexually active patients was 29.5 ± 2.6. No spouse reported discomfort during intercourse.

CONCLUSIONSVaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis is an effective and feasible approach for patients with Mayer-Rokitansky-Kuster-Hauser syndrome. The procedure has satisfactory long-term anatomical and functional results. The use of the acellular allogenic dermis is limited by the high price and the potential infection.

The aim of this study was to investigate how the killer immune globulin-like inhibition receptor (KIR) in match with HLA-Cw impacts on NK cell activity. Mononuclear cells were isolated in 20 ml peripheral blood from 27 healthy persons by Ficoll-Hypaque and purified by NK cell isolation kit. Target cells were mononuclear cells isolated from bone marrow of 30 de novo AML patients. The KIR expression were detected by flow cytometry with antibodies against CD158a, CD158b. The 2 ml of peripheral blood from healthy persons and AML patients were collected, the DNA was extracted by using PROTRANS method, the HLA-Cw and KIR gene were detected by PCR-SSP typing with sequence specific primers. The NK cell cytotoxicity against AML cells was determined by MTT after combination of KIR with HLA-Cw gene. The results indicated that the purity of NK cells was (90.8 +/- 6.08)%. The less the KIR/HLA-Cw matched, the more activity was shown in NK cells. When no match of NK cell/target cell (KIR/HLA-Cw) there was, the cytotoxicity was (50.66 +/- 8.40)%, 1 or 2 matches showed cytotoxicity of (38.28 +/- 6.71)% and (19.74 +/- 4.15)% (p < 0.001). Expression level of KIRs on NK cells also was related with cytotoxicity level (p < 0.001). It is concluded that the interaction between inhibitory KIR and HLA ligands, and also expression level of KIRs on NK cells both impact significantly on NK cell function, that the less match of KIR/HLA-Cw, and the less expression of KIRs on NK cells result in the stronger NK cell cytotoxicity.

Under the guidance of the concept of fast tract surgery (FTS), peri-operative managements including pre-operative, intra-operative and post-operative treatments can be optimized to accelerate the rehabilitation of surgery patients. Post-operative recovery of gastrointestinal functions is one of the key links of FTS, in which Chinese medicine has certain features and advantages over it. Current assessments on post-operative gastrointestinal functions recovery include clinical and laboratory assessments, but there is still no industrial assessment received by all. The current situation of post-surgery assessment of peri-operative gastrointestinal functions was studied in this paper, and the research orientation of this field was analyzed and prospected.
