Medical Postgraduates' development of ego-identity has close relation with their physical and mental health. The implication of development of ego-identity involves ego-cognition,their relationship with environment and group. This paper analyzes factors which influence the development of ego-identity, including change of role, multiple pressures on medical graduates, and the loss of sense of belonging. In order to make ego-identity develop harmoniously, it is necessary to enhance role identification, ego identification and the identification of interpersonal environment.

ObjectiveTo observe the clinical efficacy of acupoint application plus modified Yu Ping Feng decoction in treating cold due to weak constitution.MethodNinety-six patients with cold due to weak constitution were divided into two groups. The control group was intervened by regular Western medicine, while the treatment group was by acupointapplication plus modified Yu Ping Feng decoction.ResultThe total effective rate was 91.7% (44/48) in the treatment group, significantly higher than 79.2%(38/48) in the control group. A one-year follow-up study found that the disease duration and relapse frequency in the treatment group were markedly shorter and less than that in the control group (P<0.05).ConclusionAcupoint application plus modified Yu Ping Feng decoction can produce a significant efficacy in treating cold due to weak constitution.

It is of vital importance for medical postgraduates to strengthen moral construction.Based on Bourdieu's field theory,the paper puts forwards methods to enhance the influence of moral education by forming of moral habitus by self-education,clinic practice and academic study and the accumulation of moral educational capital by the combination of mentors,society,schools,families and peer groups.

With the improvement of MRI equipment performance and the usage of multi-channel high sensitivity coil, the application of the diffusion-weighted imaging (DWI) in the abdomen has been achieved. And the DWI has great significance in the diagnosis and differential diagnosis of renal tumors. In this article we reviewed advantages and limitations of magnetic resonance diffusion weighted imaging technology diagnosis in renal cell carcinoma, and also reviewed the latest research progress of DWI technology in the use of kidney.

Objective To investigate the significance of Human papilloma virus(HPV)typing in the screening of cervical dis-ease.Methods 687 cases of gynecological patients in the hospital were enrolled in the study,whose HPV-DNA genotype was detec-ted by real-time fluorescence quantitative PCR(FQ-PCR).In addition to that,389 healthy women who took gynecological examina-tion in the hospital in the same period were enrolled in the study,HPV-DNA quantitative detection were performed on those people (FQ-PCR were used)firstly,and the persons with more than 5×102 IU/mL HPV-DNA were tested for the HPV-DNA subtype. Results In the 687 cases of gynecological patients,164 cases were HPV positive which accounted for 23.9%;The single-infection patients accounted for 74.3%,mixed infection accounted for 25.6%.The mixed infection included 2 -4 types of infection,among which the double infection was most common.The common type were HPV16,52,58 and 35.In 389 cases of healthy women,29 ca-ses were found HPV positive,which accounted for 7.5%;The single infection accounted for 79.3%,mixed infection accounted for 20.7%,mixed infection included 2-3 types of HPV infection,in which double infection is the most common situation.The common type were HPV52,58,16 and 18.Conclusion HPV infection is the major cause of cervical cancer,HPV detection and typing con-tribute to cervical cancer screening and its prevention.

Purpose:To study the expression of P53 and its relationship with hepatitis B virus(HBV) infection in hepatocellular carcinomas (HCC) and chronic liver diseases.Methods:HBsAg, HBcAg and P53 were detected by immunohistochemical staining and HBV DNA by in situ hybridization with total 98 cases of chronic hepatitis, liver cirrhosis, paratumor cirrhosis , HCC and normal liver tissue. Results:The positive rates of HBsAg, HBcAg and HBV DNA were 61.9%(13/21),42.9%(9/21) and 75.0%(12/16) in chronic hepatitis;64.0%(16/25),36.0%(9/25) and 83.3%(15/18) in liver cirrhosis; 72.7%(16/22),61.1%(11/18) and 85.7%(12/14) in the paratumor cirrhosis,as well as 45.2%(14/31),50.0%(14/28) and 64.3%(9/14) in HCC . The positive rate of P53 protein was 27.9%(12/43) in HCC. It was negative in the other groups.Conclusions:The expression of P53 occurs in the later stage of HCC .The infection of HBV is not related to the positive rate of P53 protein in HCC.

Objective To study the expressions of P57~(kip2) mRNA and genetic instability of P57~(kip2) in human hepatocellular carcinoma (HCC).Methods In situ hybridization(ISH) was used to detect the expression of P57~(kip2) mRNA in HCC.MSI and LOH were detected by PCR-polyacrylamide gel electmphoresis-silver staining method.Results There was no expression of P57~(kip2) mRNA found in normal liver tissue.The expression rate of P57~(kip2) mRNA in both pericancerous cirrhosis and hepatocellular carcinoma was 26.7%(8/30).LOH was not identified in 30 cases on three microsatellite loeies;there were 2 microsatellite loeies showing MSI,the total rate of MSI was 16.7%.There was correlation found between the MSI of D11S1760 locies and the expression of P57~(kip2) mRNA(P＜0.05).Conclusion The disorder expression of P57~(kip2) mRNA indicated that P57~(kip2) might be involved in hepatocarcinogenesis and prognosis.MSI may be one of the reasons that explains the disorder expression of P57~(kip2) mRNA in hepatocarcinogenesis and prognosis.

OBJECTIVETo evaluate the colorectal cancer incidence among compliers and non-compliers in the population of colorectal cancer screening area, and to provide scientific basis for health economic evaluation of cancer screening.

METHODSBy screening different years build queue, to retrospectively compare the data of colorectal cancer screening from January 1, 2008 to December 31, 2013 and the data of cancer registration, and to analyze the colorectal cancer incidence rates among screening compliers and non-compliers, and to compare the average intervals between the end of screening and clinical cancer diagnosis using SPSS 19 statistical software. Mantel-Haenszel test was performed with a statistical significance level of α = 0.05.

RESULTSThe non-compliance rate was 38.24% among males and 28.49% among females (P < 0.001). The non-compliance rate was highest in the 40-44 and 70-74 years age groups and lowest in the 50-59 years age group. The compliers of the screening were followed up for 476,049 person-years, and there were 51 cases of colorectal cancer, with an incidence rate of 10.71/100,000. The non-compliers of the screening were followed up for 259 183 person-years, and there were 66 cases of colorectal cancer, with an incidence rate of 25.46/100,000, which was 1.38 times higher than that of the compliance group (χ2 = 21.699, P < 0.001). The incidence rate of colorectal cancer among subjects who were positive in initial screening but refused to receive an electronic colonoscopy was as high as 164.40/100,000, and the average delay time was 20.8 ± 16.8 months.

CONCLUSIONSThe colorectal cancer screening adherence among women is better than among men, and that of 50-54 years and 55-59 years age groups is better than in other age groups. The subsequent incidence rate of colorectal cancer in the non-compliance group is significantly higher than that of the compliance population.
