BACKGROUND:According to the theory of Traditional Chinese Medicine, stimulating certain acupoints of the body after exercise may improve its antioxidant capacity, but different acupoints have different effects. OBJECTIVE:To compare the effect of different acupuncture combinations on the antioxidant capacity of myocardial and liver tissues in rats after exhausted swimming exercise, and screen out the optimal acupoint combination for exercise-induced fatigue. METHODS:Seventy Sprague-Dawley male rats were divided into five groups: control group (n=10), model group (n=15),Sanyinjiao +Zusanli group (n=15),Shenshu +Zusanli group (n=15),Dazhui+Zusanli group (n=15). Except the control group, rats in the other four groups were subject to exhausted swimming. In the three acupuncture groups, rats were given acupuncture at corresponding acupint combinations at 15 minutes after exercise. RESULTS AND CONCLUSION:Compared with the control group, the activities of superoxide dismutase and glutathione peroxidase in the myocardial and liver tissues were significantly reduced in the model group, while the malonaldehyde content in cardiac muscle was significantly increased. Compared with the model group, the activities of superoxide dismutase and glutathione peroxidase in the cardiac muscle were significantly increased inSanyinjiao +Zusanli group, the superoxide dismutase in liver tissue was significantly increased inShenshu+Zusanli group, the malonaldehyde content in the myocardial tissue was significantly decreased in Sanyinjiao +Zusanli group and Dazhui +Zusanligroup, the malonaldehyde content in the liver tissue was significantly decreased in Sanyinjiao +Zusanligroup. Different acupuncture combinations have different effects on the activities of superoxide dismutase and glutathione peroxidase, as wel as the malonaldehyde content in the myocardial and liver tissues of fatigued rats. Acupunture could increase the antioxidant ability in cardiac muscle of rats and the best combination might beDazhui+Zusanli; acupoint combinations ofShenshu +Zusanli andSanyinjiao +Zusanli are specific for liver tissue.

Objective To investigate the effect of cinobufacin on P53,PTEN and HIF-1αin patients with advanced lung cancer.Methods 100 cases with advanced lung cancer were divided into two groups.control group(n=50) were treated with routine treatment, experiment group(n=50) on the base of the control group with 0.3 g cinobufacin,3 times per day oral.P53, PTEN, HIF-1α,tumor marker,survival rate and mortality were compared after the treatment.Results Compared with the control group,the serum levels of P53, HIF-1αexpression level was lower(P<0.05),PTEN expression level was higher (P<0.05),CEA,NSE,CYFRA21-1,CA125 were lower(P<0.05);the survival rate was higher, the mortality was lower(P<0.05). Conclusion Cinobufacin can regulate the advanced lung cancer patients serum P53, PTEN and HIF-1αlevels and reduce the tumor markers levels, improve the survival rate.It is of great importance for clinical treatment of advanced lung cancer.

Objective To explore the effect of endothelial progenitor cells (EPCs) on the development of collateral formation in stable angina patients with serious coronary artery disease.Methods The subjects were patients ( n =92) who underwent coronary angiography (CAG) and had chronic total occlusion (CTO) in one major coronary artery.They were divided into two groups,patients without collaterals (coil-,n =50) and patients with collaterals (coll +,n =42).EPCs were isolated from peripheral blood samples and cultured.The numbers of colony-forming units (CFUs) and the vasculargenesis capacity in vitro was assayed respectively.The plasma level of SDF-1α was determined by enzyme linked immunosorbent assay.Results The number of colony-forming units ( CFUs ) [ ( 22.10 ± 4.69 ) CFUs/106 EPCs vs ( 16.90 ± 3.66) CFUs/106 EPCs ],vasculogenesis capacity in vitro (25.3 ± 3.2 vs 17.4 ± 2.6) and plasma level of SDF-1 α[ (243.7 ± 19.2 ) ng/ml vs ( 203.1 ± 17.8) ng/ml,P ＜ 0.01 ] in coll + group were higher than that of coll group.It had a positive correlation between the level of collateral circulation and the numbers of CFUs,vascular genesis activity of circulating EPCs and plasma level of SDF-1αt( r =0.74,0.69,0.82,0.81,0.64,P ＜ 0.01 ).Conclusions The number of CFUs and vasculargenesis activity of EPC in coll + group with serious coronary artery disease is significantly higher than that in coll- group.These changes may be related to the increase of plasma SDF-1 α.The method improving the numbers and function of EPCs,increasing the activity of SDF-1 α may benefit the patients with coronary artery disease.

The principal investigator responsibility system has been progressively under implementation at some of the domestic medical universities. However, since there are big differences between military medical universities and civilian ones in terms of organizational structures, tasks to be committed, functions and personnel systems, military medical universities have to consider own characteristics and well handle the following four pairs of relations in the process of implementing principal investigator responsibility system: the relation between the subject groups and the teaching and research sections, the relation between the subject research and the discipline construction, the relation between the subject research and the personnel training, and the relation between the collective assessment and the individual assessment in the process of performance assessment.
