Objective To explore the expression and clinical value of major histocompatibility complex class-Ⅰ related chain A (sMICA) molecule in serum of patients with renal tumor.Methods From March 2013 to July 2013,60 patients with renal tumor,including 37 male patients and 23 female patients were enrolled in this study as experimental group.The mean age was 46 years (range 34-76 years).The pathological diagnosis included renal cell carcinoma in 48 cases and renal angiomyolipoma in 12 cases.The stage classification included T1 stage in 20 cases,T2 stage in 14 cases,T3 stage in 10 cases and T4 stage in 4 cases.Lymphatic metastases were found in 11 cases and metastases in other organs were found in 4 cases.Another 20 healthy volunteers were enrolled as control group,including 10 male and 10 female.The mean age was 31 years (range 24-50 years).The ELISA method was used to detect the soluble MICA's (sMICA) level in serum.And the results were compared with tumor's malice,TNM pathology stages,metastasis.In 15cases with renal cell carcinoma,the expression of MICA molecule in tumor masses and paraneoplastic masses was measured by immunohistochemical (IHC) method.The quantitative expression of MICA-mRNA was detected by RT-PCR in 9 tumor masses and 3 paraneoplastic masses.Results The level of sMICA in renal malignant tumor group was (348.5±32.5) pg/ml,while the sMICA's level in benign renal tumor groups was (289.3±30.4) pg/ml and that in the control group was (168.4±43.2) pg/ml.The level of sMICA in malignant group is statistically higher than that in benign group and control group (P＜0.05).The level of sMICA in T1 、T2 、T3 and T4 stage was (304.3±27.4),(308.4±26.8),(368.3±33.4),(378.4±43.4) pg/ml,respectively.Insignificant difference only demonstrated between T1 and T2 stage.The level of sMICA in those patients with and without lymphatic metastasis was (326.2±32.4),(319.4±32.5) pg/ml,respectively (P＞0.05).Significant difference in the sMICA level could also be observed between patients with other organ metastasis (373.4±45.4) pg/ml and those without metastasis (346.4±31.5) pg/ml (P＜0.05).The IHC results revealed that high expression of MICA molecule in tumor cell.However,this oppsite result was demonstrated in cells located in paraneoplastic tissues.In the results of RT-PCR,the MICA-mRNA level (2.03) in tumor masses was significantly higher than that in pareneoplastic masses (0.77) (P＜0.05).Conclusions MICA highly expressed in renal tumor,and its expression correlates with tumor's malice,TNM pathologic stages,and metastasis.

Objective To study the relationship between general self-efficacy, social support, psychological health and working efficiency.Methods Using General Self-efficacy Scale (GSES), Social Support Rating Scale, Symptom Checklist-90 (SCL-90) and supervisor's rating of work efficiency to investigate 262 nurses. And using correlation and regression analyze the results. Results Correlation analysis found that general self-efficacy and subjective social support had significant negative correlations with the general symptomatic index of SCL-90( r =-0.31,-0.29,P <0.05).Results of regression analysis showed that general self-efficacy, objective social support, using of the social support, and general symptomatic index of SCL-90 had significant effects on working efficiency (β=0.41,0.36,0.35,-0.28,P <0.05).Conclusion Working efficiency of nurses is mainly effected by general self-efficacy, objective social support, using of the social support and psychological status. As a result,all these factors should be taken under consideration in order to improve working efficiencies of nurses.

Objective To investigate the treatment of recipients carrying hepatic virus after renal transplantation. Methods Of the 14 patients, 8 carried HBV and 4 HCV, and the other 2 both HBV and HCV. HBV DNA or RNA was negative before transplantation.Results During the follow-up period of 3 to 20 months, 10 patients had liver dysfunction with higher ALT and AST, but negative for HBV DNA and/or HCV RNA. After adjusting the dosage of immunosuppressants and treatment of liver protection, liver function of these patients all restored to normal level.Conclusion In the hepatic virus carriers receiving renal transplantation, liver dysfunction caused by drug-induced liver damage or hepatic viral injury should be distinguished and corresponding treatment should be given in time.

Objective To explore the significance of complement split product C4d in monitoring chronic rejection of renal allografts in rats.Methods Healthy closed population rats were used as donors and SD rats as recipients. The Wistar to SD model of graft rejection was developed. All the 42 recipients were randomly divided into 2 groups: group A receiving nothing except CsA (5mg?kg~ -1 ? d~ -1 ) in the first 10 days after operation, and group B receiving MMF (10 mg/kg) and CsA after operation. On the 3rd, 5th and 10th week, all the allografts were tested by light microscopy and immunofluorescence. Pathological changes of the kidneys and the expression of C4d in allograft tissue were observed.Results From the 3rd week, the rats in group A showed light pathological changes of chronic rejection and they became more and more obvious as time increased. Pathological changes occurred in group B at the 5th week and lighter than in group A. At the same time, C4d deposition in PTC was obviously observed on the 3rd week in group A, and on the 10th week C4d widespread deposition in allografts.Conclusion The deposition of complement split product C4d in allografts appears earlier than pathological change of chronic rejection, which can be regarded as a significant indicator to predict chronic rejection of renal allografts.

Objective: To select the common syndrome factors of menopausal syndrome through questionnaire investigation among experts. Methods: Firstly, a questionnaire was constructed on the basis of our previous research, and then investigation of the experts by the questionnaire was carried out. The experts came from twelve tertiary hospitals (6 cities) in China, and engaged in clinical practice of gynecology of traditional Chinese medicine (TCM) or integrated traditional Chinese and Western medicine. The common TCM syndrome factors of menopausal syndrome were selected based on consent degree of the experts in mean value, full marks ratio, rank sum and variation coefficient. Results: One hundred sets of the questionnaires were sent out and ninety-eight sets were returned back. The callback rate was 98%. In accordance with cumulative percentage of expert agreement and complete agreement more than 50% and the coefficient variation less than 0.25, we confirmed the common TCM syndrome factors of menopause syndrome. The syndrome factors related to disease location were kidney, liver, heart, and spleen, and those related to the nature of disease were yin deficiency, deficiency of essence, yang deficiency, hyperactivity of yang, qi deficiency, qi stagnation, blood deficiency, and blood stasis. Conclusion: Expert consultation questionnaire can collect consensus opinions of experts and is effective for identifying common TCM syndrome factors of a disease. The TCM syndrome factors acquired through the study may provide the evidence for establishment of TCM syndrome diagnosis criteria for the disease in future.
