The Journal of Practical Medicine 2017;33(12):2032-2035
Objective To investigate the correlation between gut microbiota and hepatitis B virus(HBV) infection at different stage. Methods 84 patients aged 25 ~ 40 were enrolled in the study,the ALT,AST and HBV antigens and antibodies qualitatively detected. Then they were divided into four groups based on HBV related antigens and antibodies qualitative detection according to guideline for chronic HBV infection:48 in the protective antibody positive group where vaccine injection was performed for producing protective antibodies ,14 in the HBV recovery group 9 in chronic HBV infection group And 13 in antibody negative group where vaccine injection was done. Their fecal samples were collected and total DNA were extracted and subjected to enterobacterial repetitive intergenic consensus sequence polymerase chain reaction(ERIC-PCR). After ERIC-PCR,gel electrophoresis and genetool software were used to analyse the differences in the amount of bands and the position of main bands between groups. Results The amounts of bands in the antibody negative and chronic HBV infected groups were significantly smaller than the protective antibody group and HBV recovery group. The position of main band in the protective antibody group and HBV recovery group were wildly spread within groups ,and most main bands in the HBV recovery group were above 282 bp. The main bands in the antibody negative and chronic HBV infected groups were centralized in 60 ~ 70 bp. Conclusions Compared with the protective antibody group and HBV recovery group ,the richness of gut microbiota in the antibody negative and chronic HBV infected groups are significantly decreased and lack of microbiota above 200 bp in ERIC-PCR.

9.The roles and mechanism of tumor-derived factors in the development of cancer cachexia
Parenteral & Enteral Nutrition 1997;0(04):-
Syndrome of cachexia,which is a common feature of many types of cancer,characterized by loss of adipose tissue and skeletal muscle,is responsible not only for a poor quality of life and poor response to chemotherapy,but also a decreased survival time.It can not be fully explained by the accompanying anorexia,because increasing nutrient support is unable to reverse the wasting syndrome.Although patients with cachexia frequently show an elevated resting energy expenditure,cachexia can occur with a normal energy expenditure.Lipid mobilizing factor and proteolysis inducing factor,two tumor-derived factors,can directly mobilize fatty acids and amino acids from adipose tissue and skeletal muscle respectively.It is important of the knowledge about the roles and mechanism of LMF and PIF in the development of cancer cachexia,which should lead to the development of new therapeutic methods.
