In the peacekeeping operations of the United Nations,medical personnel need to have clear legal compliance to solve the ethical problems encountered.The existing laws and regulations are impractical with a nar row cover,which can't meet the actual requirements.Based on the literatures and practical examples,this paper discussed the medical ethical problems involved in peacekeeping operations using the three-step method (empirical investigation,comparative analysis and summarization),and provided suggestions and countermeasures to the construction of medical ethics in peacekeeping medical support.

Objective To observe and compare the curative effects of zoledronic acid (ZA) combined with radiotherapy and ZA combined with chemotherapy in the treatment of bone metastasis of non-small cell lung cancer (NSCLC). Methods Seventy-eight patients with NSCLC bone metastasis treated by radiotherapy or chemotherapy were taken in our hospital from January 2010 to June 2014, including 39 cases of ZA combined conventional fractionation radiotherapy (radiotherapy combined group), and 39 cases of ZA combined with chemotherapy (paclitaxel liposome + cisplatin) (chemotherapy combined group). Each group had 39 cases. WHO objective evaluation standard, efficacy evalulation of solid tumor metastasis and curative effect standard grading of pain, anticancer agent toxicity classification standard, Karnofsky standard were used for evaluating and analyzing the patients with primary lung tumor, bone metastasis, degree of pain, adverse reactions and functional status (once before and after the treatment). Results The efficiency rate of primary lung tumor, the efficiency rate of bone metastasis, the total effective rate of pain relief and the improvement rate of functional status (Karnofsky score increased by 10 points or more)in the radiotherapy combined group and chemotherapy combined group were 82.05 % (32/39) vs. 79.49 % (31/39), 48.72 % (19/39) vs. 51.28 %(20/39), 82.05 % (32/39) vs. 84.62 % (33/39), 66.67 % (26/39) vs. 71.79 % (28/39) respectively, and the differences were not statistically significant (the values of x2 were 0.224, 0.237, 0.195, 0.259 respectively, all P> 0.05); Although the two groups showed low-grade fever, bone marrow suppression, esophagitis, liver and kidney damage, gastrointestinal reactions and other adverse reactions, the adverse reactions of two groups were close to [28.21 % (11/39) vs. 30.77 % (12/39)] (x2 = 0.314, P> 0.05). Fortunately, these reactions were controlled well after symptomatic treatment. Conclusion ZA combined with radiotherapy or chemotherapy is a safe and effective way for bone metastasis of NSCLC, which should be taken based on the individual condition of the patients.

Methods Laparoseope,duodenoscope and choledochoscope were combined to treat 293 cases with cholelith-iasis which included 2 cases cholecystolithisasis, 131 cases were cholecystolithiasis with secondary choledocholith,28 cases with primary choledocholith,39 cases with calculus of intrahepatic duct,93 cases with calculus of intrahepatic or extrahepatic duct. Results The program had minor trauma, mild suffering, and less operative complications,compared with traditional open operations. Conclusion The combined treatment of laparoscopy, duodenoscopy, choledochoscope and surgery for the cholelithiasis in the primary hospital is feasible, safe and effective.

OBJECTIVETo evaluate the value of endometrial microvessel density (MVD) in assessing the endometrial receptivity during the peri-implantation period.

METHODSA total of 104 patients undergoing in vitro fertilization and embryo transfer (IVF-ET) treatment were analyzed retrospectively. The subjects were divided into clinical pregnancy group (50 cases) and nonpregnant group (54 cases) according to the IVF-ET outcome. Endometrial tissues were collected 7 days after the natural ovulation prior to IVF-ET for measurement of the endometrial MVD using electron microscopy, which was analyzed in relation to the clinical outcome of the treatment.

RESULTSThe endometrial MVD was significantly higher in the clinical pregnancy group than in the nonpregnant group [(4.12∓1.84)% vs (3.46∓1.26)%, t=-2.127, P=0.036). ROC curve analysis showed that the MVD had an area under the curve slightly over 0.5 (0.598) for predicting clinical pregnancy, suggesting a poor specificity in predicting the clinical outcome of the treatment.

CONCLUSIONIn IVF-ET cycles, the endometrial MVD during the peri-implantation period is helpful for assessing the endometrial receptivity, but the specificity remains low.

The study was aimed to isolate and establish mesenchymal stem cell line from adult murine bone marrow as well as to identify its biological characteristics and differentiation potential. Bone marrow cells (BMCs) were collected by flushing the femurs and tibias of 4 - 5-week-old male C57BL/6 mice, and were inoculated at a concentration of 1 x 10(6)/cm(2). mMSCs were isolated, enriched and expanded by using bone marrow adherant culture and monoclonal culture. The characteristics of the cells, such as morphology, growth pattern, cell cycle, phenotype, karyotype and multipotent differentiation potential, cytogenetic stability and tumorigenesis were determined. The results indicated that the cell population consisted of spindle- and star-shaped cells, they were highly positive for CD29, CD44, Sca-1, MHC-I, moderate positive for CD13, CD90.2 and negative for CD117, CD45, Flk-1 and MHC-II. mMSCs could be induced to differentiate into adipocytes, osteoblast cells and chondrocytes. It is concluded that mMSC can be isolted, expanded and enriched by using bone marrow adhcrent culture and monoclonal culture. No tumor formations are observed for 3 months in nude mice after subcutaneous injection. mMSCs retain their properties after at least 30 passages in culture as well as from frozen stocks.

OBJECTIVETo study the association of human epidermal growth factor receptor family molecules expression in gastric cancer tissues with the prognosis of patients with gastric cancer.

METHODSClinical data of 161 patients with gastric cancer undergoing gastrectomy in Jiangsu Cancer Hospital between January 2006 and January 2007 were analyzed retrospectively. The expression of HER1, HER2, HER3 and HER4 was detected by immunohistochemistry. Association of the expression of HER family with the prognosis of patients was examined. Kaplan-Meier method was used to analyze the survival.

RESULTSHigh expression rates of HER1, HER2, HER3 and HER4 were 46.0% (74/161), 10.6% (17/161),55.9% (90/161) and 68.3% (110/161) respectively. Univariate analysis revealed that high expression of HER3 was associated with tumor invasion depth, lymph node metastasis, stage, neurovascular invasion, and overall 4-year survival. High expression of HER4 was associated with tumor distant metastasis and stage. High co-expression of HER2 and HER3 was associated with overall 4-year survival (P=0.023). Multivariate analysis revealed that high expression of HER3 and stage were prognostic independent factors.

CONCLUSIONUp-regulated expression of HER3 is associated with the poor prognosis in gastric cancer patients.
