Objective:To investigate the effects of sodium butyrate,the most important short chain fatty acids,on growth suppression and apoptosis of SHG-44 glioma cell line.Methods:Human glioma SHG-44 cells were treated with 2 mmol/L and 4 mmol/L sodium butyrate.The inhibition of cell growth was assessed by MTT spectropotometric analysis and immunohistochemisty methods.The apoptosis was observed by reverted microscope and transmission electron microscope.And mitochondrial transmembrane potential was detected by rhodamine 123 dyeing,which confirmed that SHG-44 cells suffered a mitochondrial path apoptosis.Results:Sodium butyrate treatment resulted in significant inhibition of cell growth,with proliferating cell nuclear antigen expression weakened.Furthermore,4 mmol/L sodium butyrate could induce the SHG-44 cells apoptosis.It was proved that cellular membrane shrunk,vacuoles existed in plasm,and apoptosis bodies occurred by morphologic observation.In addition,the △?m was decreased in apoptosis cells after 4 mmol/L sodium butyrate treatment.Conclusion:These results indicate,in malignant glioma SHG-44 cells,sodium butyrate could not only suppress cell growth,but also induce apoptosis by a mitochondrial path.

In view of the increased incidences of cardiac arrest outside hospital year by year and younger tendency of the patients,foreign medical education practice showed that school-age children accepting cardiopulmonary resuscitation (CPR) skill training will benefit most from this survival skill in the future.This article elaborated on the meaning and methods of promoting CPR training in primary and middle school based on the present situation of CPR in order to promote its further development.

Objective To investigate the effect of sodium butyrate on the growth suppression and cellular differentiation of cultured SHG 44 glioma cell line Methods Human glioma SHG 44 cells were treated with 2 mmol/L sodium butyrate The inhibition of cell growth was assessed by MTT spectrophotometric analysis and AgNORs analysis The cellular differentiation was determined by flow cytometry, electron microscopy, immunohistochemical method and agglutination test Results Treatment of SHG 44 cells with sodium butyrate resulted in significant inhibition of cell growth and G1 S transition in time dependent and dose dependent manners Sodium butyrate could induce differentiation of SHG 44 cells with regularized nuclei and increased heterochromatins The mitochondria and rough endoplasmic reticulum increased in density in normal state Furthermore, SHG 44 cells expressed more GFAP but less vimentin, and the agglutination degree decreased obviously Conclusion Sodium butyrate may suppress glioma cells growth and induce differentiation of human glioma cells

Objective To investigate the effect of Yiqi Yangyin Huoxue Decoction combined with Western medicine therapy , while on this basis the observation group was combined with the on serum CRP ,TNF‐α,blood lipid and hemorheology levels in cor‐onary heart disease angina pectoris .Methods Totally 114 patients with coronary heart disease(CHD) angina pectoris were random‐ly divided into observation group (n=57) and control group (n=57) according to the random number table method .The control group was treated with Western medicine treatment ,while on this basis the observation group was combined with the therapy of Yiqi Yangyin Huoxue Decoction .The treatment cource was 4 weeks in the two groups .Serum CRP ,TNF‐α,blood lipids ,hemorheol‐ogy levels ,frequency and duration of angina pectoris attack ,efficacy of angina pectoris and ECG and adverse reactions were contras‐tively analyzed in the two groups .Results The levels of serum CRP and TNF‐αafter treatment in the two groups were decreased (P<0 .05);sthe serum levels of CRP and TNF‐α after treatment in the observation group were lower than those in the control group(P<0 .05);the TG ,TC and LDL‐C levels after treatment in the two groups were decreased (P<0 .05);the TC ,LDL‐C and TG levels after treatment in the observation group were lower than those in the control group (P<0 .05);fibrinogen ,plasma vis‐cosity and whole blood viscosityafter treatment in the two groups were decreased (P<0 .05);the fibrinogen ,plasma viscosity and whole blood viscosity after treatment in the observation group were lower than those in the control group (P<0 .05);the angina pectoris attack frequency after treatment in the two groups were reduced (P<0 .05) ,the duration was shortend (P<0 .05);but the angina pectoris attack frequency after treatment in the observation group was lower than that in the control group (P<0 .05) ,the duration was shorter than that in the control group (P<0 .05);the total effective rate of angina pectoris and ECG in the observa‐tion group was higher than that in the control group (P<0 .05) .The two groups had no serious adverse reactions during the treat‐ment process .Conclusion Yiqi Yangyin Huoxue Decoction combined with Western medicine can reduce serum CRP ,TNF‐α,blood lipid and hemorheologic levels in CHD angina pectoris ,and has remarkable curative effect with safety and reliability .

BACKGROUND:Bone marrow mesenchymal stem cels have the ability to differentiate into a variety of non-hematopoietic tissue cels. Effects of magnetic fields on the differentiation of bone marrow mesenchymal stem cels have attracted a lot of attention in recent years. OBJECTIVE:To summarize the effects of magnetic fields on the differentiation of bone marrow mesenchymal stem cels towards osteoblasts, chondrocytes, adipocytes, nerve cels and cardiomyocytes, which provide references for the research and application of tissue engineering seed cels as wel as the clinical applications of magnetic fields. METHODS:The first author performed a data retrieval of PubMed and CNKI databases from 2000 to 2015 to search the articles addressing the effects of magnetic fields on the differentiation of bone marrow mesenchymal stem cels, and reviewed the literatures systematicaly. Finaly, 40 articles were chosen for further analysis. RESULTS AND CONCLUSION:Magnetic fields can promote the differentiation of bone marrow mesenchymal stem cels towards osteoblasts, chondrocytes, nerve cels and cardiomyocytes, and inhibit the differentiation of bone marrow mesenchymal stem cels towards adipocytes. There are optimal frequency and intensity in the induction of magnetic fields on the differentiation of bone marrow mesenchymal stem cels. In general, low-intensity and low-frequency magnetic fields have more obvious effects on bone marrow mesenchymal stem cels. The facilitation of magnetic fields on the differentiation of bone marrow mesenchymal stem cels is also a time-dependent behavior.

Objective:According to the tumor of children psychology, explore a set of suitable for children accurate tumor radiotherapy positioning method, in order to improve the positioning accuracy, thus improve the tumor clinical cure rate.Methods: 1.Eliminate fear; 2.Adaptability training; 3.The methods of psychological suggestion. Evaluation method: take psychological induction of radiation induced by radiation therapy in children with and without taking mental children from the placement time, downtime in drug utilization rate, treatment rate and bit error rate comparison.Results: There is obvious difference between two groups (P<0.05).Conclusion: radiotherapy positioning of children with psychological intervention in the method, can improve the treatment of children's compliance.
