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 compare the clinical efficacy of moxibustion Zhiyin with knee chest decubitus,ear acupoint magnetic bead press combined with knee chest decubitus and knee chest decubitus in correction of breech position,thus to provide more safe and effective correction method for the clinical treatment.Methods 150 pregnant women with breech were selected.They were randomly divided into observation group Ⅰ,observation group Ⅱ and control group according to the digital table,50 cases in each group.The control group was treated with knee chest decubitus to correct breech position,the observation group Ⅰ was given moxibustion Zhiyin combined with knee chest position,the observation group Ⅱ was given ear acupoint magnetic bead press combined with knee chest decubitus.Results The effective rates of the observation group Ⅰ and observation group Ⅱ were 96％,92％,respectively,which were higher than 76％ of the control group,the difference were statistically significant (χ2=5.09,4.18,all P＜0.05).The effective rate between the observation group Ⅰ and observation group Ⅱ showed no significant difference (P＞0.05).Conclusion Moxibustion Zhiyin combined with knee chest decubitus and ear acupoint magnetic bead press combined with knee chest decubitus in the correction of breech position have short course of treatment,high success rate,and are more economical and convenient,with high safety and good curative effect,which are worthy of promotion.

Objective:To investigate the effects of Metarhiziun taii polysaccharide on the immunity activity of the diabetic mellitus model mouse.Methods:To build stables type Ⅰ diabetic model mouse by intraperitoneal injecting small dose streptozotocin ( STZ) continuously.Then observeing weight changes,detecting empty stomach serum glucose,immune organ index( include spleen and thymus),peritoneal macrophage phagocyte ability,spleen lymphocyte multiplication and immunoglobulin IgG′s and complement C3,C4 content in blood serum of the diabetic rats.Results:The weight of model mouse had been improved by Metarhiziun taii polysaccharide, serum glucose had been improved degrade of the ability of model mouse.T,B lymphocyte proliferation had been increased obviously by middle and high dose polysaccharid,spleen index,IgG′s and C3,C4 content in blood serum of the diabetic rats could be improved by high dose distinctively.Thymus index and the capacity of peritoneal macrophage phagocyte would enhanced by middle and high dose polysaccharide inject.Conclusion:The immune function and serum glucose of typeⅠdiabetic mode rats could be improved by intra-gastriced Metarhiziun taii polysaccharide.

Objective To analyze CT manifestations of inguinal canal lipomas (ICLS).Methods CT datas of 104 pa tients with ICLS was retrospectively analyzed.And the imaging features were observed by MPR.Results The main CT manifestations of the ICLS were fat density in the inguinal canal and were unconnected with the abdominal fat.Among the 104 ICLSpatients,male (90/104,86.54％) was more than famale(14/104,13.46％;x2=55.538,P＜0.001).Thele sions were located at bilateral sides in 8 cases,left side in 66 cases and right side in 30 cases.The lesions in left side were more than those in right side (x2 13.500,P＜0.001).The mean maximum cross-sectional area of ICLS was (3.89 ± 2.12)cm2.There was no statistically significant difference between male and famale in maximum cross-sectional area (t=1.038,P=0.302).Conclusion In ICLS patients,male is more than famale.And more lesions are located at the left side.The CT manifestations of ICLS have certain characteristics,and MPR images are helpful in diagnosing ICLS.

Objective To study the distribution of variable number tande repeat(VNTR) polymorphisms of the platelet membrane glycoprotein Ⅰ b? in Han nationality at Harbin and the relationship between these polymorpbisms and cerebral infarction(CI).Methods The identification of alleles and genotypes of VNTR polymorphism of the glycoprotein Ⅰ b? gene was performed by polymerase chain reaction (PCR)in 200 healthy individuls and 200 CI patients(77 lacunar infarction patients and 123 atherosclerotic thrombotic infarction patients),to analyze The relationship between gene polymorphisms and cerebral infarction.Results(1)There were three types of alleles:B、C、D,and five types genotypes:BC,BD,CC, CD,DD in Harbin Han nationality.No person with A allele and BB genotype was found.(2)No statistically significant differences of GP Ⅰ b? gene VNTR polymorphism was found between CI patients or subtype CI patients and controls(P=0.412 and 0.572,respectively).Conclusions(1)This study indicates that the C and D alleles of VNTR polymorphisms of GP Ⅰ b? are the main alleles while the CC and CD genotypes are the main genotypes in Harbin Han people.(2)Our findings indicate that no association exists between the VNTR polymorphism of platelet GP Ⅰ b? gene and CI.

Objective To investigate the correlation between human leukocyte antigens-A,-B,-DRB1 (HLA-A,-B,-DRB1) high resolution alleles and chronic renal failure (CRF) caused by immunoglobulin-a nephropathy (IgAN).Method The polymerase chain reaction-sequence-based typing (PCR-SBT) method was used to investigate the genotypes of HLA-A,-B and-DRB1 high-resolution alleles in 191 cases of CRF caused by IgAN (experimental group) and 503 healthy blood donors (control group).The alleles frequencies between two groups were compared and the association between CRF caused by IgAN and the polyrnorphism of HLA was analyzed.Result (1) There were 25 alleles at A locus,48 alleles at B locus and 32 alleles at DRB1 locus in experimental group.(2) The genetic frequency of HLAA * 2901 [Pc =0.033,OR =10.738,95％ CI (1.193,96.691)],HLA DRB1 * 1106 [Pc =0.0001,OR =0.969,95％ CI (0.944,0.994)],HLA-DRB1 * 1202[Pc =0.002,OR =1.859,95％ CI (1.259,2.745)],HLA-DRB1 * 1401 [Pc =0.021,OR =0.984,95％ CI (0.967,0.998)],HLA-DRB1 * 1602[Pc=0.015,OR=1.915,95％ CI (1.157,3.17)] in experimental group was higher than in control group (P＜0.05).Conclusion There is susceptibility association of HLA-A * 2901,HLA-DRB1 * 1106,HLA-DRE * 1202,HLA-DRB1 * 1401,HLA-DRB1 * 1602 with CRF caused by IgAN.It is concluded that there is a close genetic and immunological correlation between HLA alleles and the pathogenesis of CRF caused by IgAN.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.
