The present study reported that 5srRNA from reticulocytes of rabbit could pass into the nucleus of mouse myeloma cells SP2/0,and in the mean time DNA synthesis and cells division were markedly suppressed. In a separate experiment, the rRNA was extracted from embryonic liver and erythrocytes of rabbit or rat and analysed by agarose electrophoresis method. The result indicated that the amount of 5srRNA in various period of the development of erythrocyte is changed along with denucleation process. Thus it is likely that 5srRNA of mammalian erythrocyte plays a role in reversing malignant phenotype of tumor cells and promoting denucleation of mammalian erythrocyte through inhibiting DNA synthesis.

Objective To study the effect of 2?-(3-hydroxypropoxy)-Calcitriol (ED-71) on the cell growth and differentiation of human osteoblast-like cell line OS-732. Methods Osteoblast-like cells were cultured with various concentration of ED-71.The effects of ED-71 on proliferation and differentiation were detected by (MTT), alkaline phosphatase activity and level of osteocalcin (bone gla protein,BGP). Results The proliferation rate of osteoblast-like cells cultured for 4 days was significantly inhibited by 10~ -7mol/L concentration of ED-71. ED-71 in 10~ -8, 10~ -9mol/L concentration can significantly increase BGP level, but ED-71 in 10~ -7mol/L concentration may decrease BGP level.Alkaline phosphatase activity compared with control was not changed significantly. Conclusions ED-71 can inhibit cell growth in high concentration and improve cell differentiation in lower concentration.

Objective To study the relationship between serum 1,25 -dihydroxy vitamin D3 level and inflammatory factor in elderly primary hypertension patients.Methods Sixty -eight primary hypertension patients were selected as hypertension group,and 60 healthy subjects were selected as control group in this study.The serum 1,25 -dihydroxy vitamin D3 level and plasma inflammatory factor were measured and compared.Results The serum 1,25 -dihydroxy vitamin D3 level in the hypertension group was significantly lower,while plasma inflammatory factor in the hypertension group was significantly higher than in the control group(t =6.445,7.326,8.174,8.556,all P <0.01).Pearson correlation analysis showed that the serum 1,25 -dihydroxy vitamin D3 level was negatively related with systolic blood pressure,plasma diastolic blood pressure and inflammatory factor (r =-0.425, -0.367, -0.254, -0.263, -0.296,all P <0.05).Logistic repression analysis revealed that the inflammatory factor was a risk factor for hypertension,while the 1,25 -dihydroxy vitamin D3 level was a protecting factor for primary hypertension. Conclusion The serum 1,25 -dihydroxy vitamin D3 level is significantly lower in elderly primary hypertension patients than in healthy subjects.The serum 1,25 -dihydroxy vitamin D3 level and the inflammatory factor are predic-tive factors for hypertension.

Objective To investigate the clinical efficacy of Q-switch 1064 nm wavelength laser combining with microneedle technology for the treatment of melasma.Methods 70 melasma patients were selected in the Out-patient Department of Wuhan General Hospital of Guangzhou Military Command from July 2012 to Sept.2013.The patients were randomly divided into 3 groups:the combining therapy group (patients in this group received Q-switch 1064 nm wavelength laser combining with microneedles technology,the treatment interval was 2 or 3 weeks,and the whole course was 2-6 months);the microneedle group and the Q-switch 1064 nm wavelength laser group.The effect and the adverse reaction were observed and recorded during the treatment,and the reduced area of the pigment patch was also measured to judge the total efficacy after the course.Results The total effective rate was 78.6％ (22/28) in the combining therapy group and 40.0％ (8/20) in the microneedle group,45.5％ (10/22) in the Q-switch 1064 nm wavelength laser group.There were statistically significant differences between the combining therapy group and the other groups (P1 ＜0.05,P2 ＜0.05),without obvious adverse reaction.Conclusions It is significantly better to use American Medlite C6 Q-switch 1064 nm wavelength laser combining with microneedles technology than that of the single use of Q-switch 1064 nm wavelength laser or microneedles in the treatment for the patients with melasma.The method is also simple to handle and suitable for clinical application.

Objective To explore the change and the spectra of opportunistic infections in AIDS patients after antiretroviral treatment in He′nan province.Methods Inpatients of post treatment with disease in accordance with the criteria were selected from the Sixth People′s Hospital of Zhengzhou.A retrospective study was carried out, including the content such as gender,age,infection route,treatment time,the date of complication,and CD4+T lympho-cyte counts when the patient with complications.Disease were divided into four group:opportunistic infections,adverse drug reactions,tumor,cardio-cerebrovascular disease and diabetes mellitus.Statistic case number and incidence of every kinds of the disease in the different stages of HAART.Results (1)1 001 cases of patients were involved in the result analysis.People of 41-60 years old,the peasants and peasant workers,accounted for 57.4%and 78.9%.The infection route was mainly through blood transmission and blood collection, accounting for 83.45%.Most of the patients come from Zhumadian, Xuchang, Zhoukou, Nanyang, which were high -incidence area in He′nan.( 2 ) In 1 001 patients of post treatment, the rate of opportunistic infections was 58.4%, while adverse drug reactions was 30.5%.Bacterial pneumonia,extrapulmonary tuberculosis,oral cavity fungal infection and tuberculosis were common in opportunistic infections of patients of post treatment.The main adverse reactions were allergic dermatitis,liver injury and myelosuppression.The liver cancer case was the highest ( 8/29 ) .( 3 ) 1 001 cases were divided into 6 groups according to different count of treatment time,during 3 months of treatment,the incidence rate of opportunistic infec-tions and adverse drug reactions was the highest,accounted for 75.2% and 41.6%.After 5 years of treatment,the incidence rate of cardio-cerebrovascular disease and diabetes mellitus was 6.39%.With the prolonging of HAART time,incidence of opportunistic infections and adverse drug reactions remarkably reduced,but the occurence rate car-dio-cerebrovascular disease and diabetes mellitus increased.Conclusion In AIDS patients after HAART in He′nan at present,opportunistic infections and adverse drug reactions are main diseases and used to occur during three months after HAART.Attention will be focused on tumor, cardio -cerebrovascular disease and diabetes mellitus in AIDS patients of long-term survival.
