1.Clinical signification of hepatitis B surface antigen quantification in management of chronic HBV infection
Chinese Journal of Clinical Infectious Diseases 2014;(6):546-550
With the development of automated quantitative detection of serum hepatitis B surface antigen ( HBsAg) , HBsAg quantification is becoming increasingly important in management of chronic HBV infections.Studies have shown that HBsAg quantification together with HBV DNA load may be used to monitor the natural history of chronic HBV infection as well as to predict the clinical outcome of interferon treatment.However, there is no consensus on the clinical use of HBsAg quantification for evaluating patients′responses to nucleos( t) ide analogues therapy.This paper reviews the up-to-date clinical studies on the clinical significance of HBsAg quantification in management of chronic HBV infection.

Chinese Journal of Experimental Ophthalmology 2012;30(9):861-864
Histone acetyltransferases(HATs) faciliate histone acetylation and histone deacetylases(HDACs) serve to remove acetyl groups from histones.The activation and repression of gene expression can be regulated by the acetylation of histone or specific genes.It is certified that acetylation of related genes is down-regulated in diabetic retinopathy,retinal ischemia-reperfusion,degenerative retinopathy,infective retinopathy and retinal tumors,which results in cell apoptosis and retinal dysfunction.So the physiology and pathology of retina have a close relation.The effects of histone acetylation and deacetylases on retinal diseases are still studying because of the complexity and diversity of genetic modification io epigenetic inheritance.This article reviewed the classification of HATs and HDACs and their inhibitors,their effects and function,their relationship to retinopathy,and discuss the protection of their inhibitors to retina.

4.Advances in clinical investigation of adjuvant radiotherapy in rectal cancer
China Oncology 2000;0(06):-
Surgery has remained the mainstay of treatment of rectal cancer but due to high local recurrence rates,adjuvant chemoradiation has become standard practice for advanced rectal cancer.In 1990,postoperative chemoradiation has been established by NCI based on the results of GITSG,NCCTG and intergroup studies.However,the German CAO/ARO/AIO 94 study showed that preoperative chemoradition is better than postoperative in terms of local control and acute toxicity.The 5-year cumulative incidence of local relapse was lower in patients assigned to pre-operative chemoradiation vs postoperative treatment Grade 3 or 4 acute toxic effects occurred in 27% of patients in pre-op group vs 40% in post-op group.The corresponding rates of long-term toxic effects were 14% and 24%,respectively.Preoperative chemoradiation has been the trend of treatment of advanced rectal cancer.
5. Establishment and optimization of the amplified fragment length polymorphism reaction system of Carthamus tinctorins L. genome
Academic Journal of Second Military Medical University 2006;27(3):327-330
Objective: To study the factors affecting amplified fragment length polymorphism (AFLP) of Carthamus tinctorins L. genome, and to develop and optimize the AFLP reaction system, laying a foundation for Marker-assisted breeding of Carthamus tinctorins L.. Methods: Cetyl-trimethyl-ammonium-bromide (CTAB) method was used to extract the genomic DNA of Carthamus tinctorins L., whose concentration and purity were determined by UV spectrophotometry. The genomic DNA was digested by restricted enzyme and ligated with one-step method or two-step method so as to find out which one is more suitable. Then the products were prepared with different dilution multiples (5, 10, 15, 20, 25 and 30) for pre-amplification and with different concentrations of gradients (10, 25, 50, 75, 100, 150 and 200) for selected amplification. Then they were subjected to PAGE electrophoresis and silver-staining after denaturing at 95°C for 8 min. Results: The AFLP reaction system for Carthamus tinctorins L. genome included the following steps: the genomic DNA was precipitated with alcohol by CTAB method to avoid contamination by any inhibitors; the DNA was completely digested by Mse I and EcoR I at 37°C for 3 hours. Two-step method was superior to one-step method in this AFLP system. The digestion time was 3 hours at 37°C and ligated at 16°C over night, with Buffer 2 (NEB Company) as the specific buffer. Furthermore, the optimal dilution was 25 folds for pre-amplification and 75 folds for selected amplification. In this reaction system, the strips in PAGE electrophoresis were clear and less decomposed. Conclusion: The AFLP reaction system in this experiment is suitable for silver-stained AFLP of Carthamus tinctorins L. analysis.

China Journal of Chinese Materia Medica 2014;39(6):1058-1063
OBJECTIVETo observe the changes in the adhesive function of vascular endothelial cells (VEC) and rat monocytes induced by lipopolysaccharide (LPS) and co-cultured with smooth muscle cells (SMC) and the intervention effect of paeonol (Pae).
METHODPrimary rat vascular endothelial cells (VECs) and rat vascular smooth muscle cells (VSMCs) were cultured by predigesting and adhering tissue blocks. The VEC-VSMC co-culture model was established by Transwell chamber. LPS was used to induce VEC injury. MTT assay and LDH assay were used to determine the VEC activity. ELISA assay was used to detect IL-1beta and TNF-alpha secreted by the VEC. The immunocytochemistry assay was carried out to detect the expression of ICAM-1. The Rose Bengal Staining was used to test adhesive function between VECs and monocytes.
RESULTThe concentration of LPS-induced VEC injury was 100 microg x L(-1), and the time was 7 h. after the intervention on the above cell model for 24 h, Paeonol (15, 30, 60 micromol x L(-1)) could effectively inhibit LPS-induced VEC injury and VEC injury, significantly enhance the survival rate of LPS-injured VECs, decrease IL-1beta and TNF-alpha secreted by the injured VEC, and reduce the expression of ICAM-1, so as to inhibit the adhesion of LPS-induced VECs and monocytes.
CONCLUSIONPaeonol could inhibit IL-1beta and TNF-alpha expression to protect VECs from being injured by LPS, and reduce ICAM-1 expression to inhibit the adhesion between VECs and monocytes.
