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.

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.

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.

BACKGROUND: The number of roots and morphology of the root canal system of permanent mandibular first molars vary greatly among different populations; therefore, it is important to be familiar with the variations in the root and root canal for the location and negotiation of the canals. OBJECTIVE: To investigate the variations in the roots and root canal of permanent mandibular first molars in the Han population of southwest Shandong Province by cone-beam CT. METHODS: 656 patients undegoing cone-beam CT examination at the Department of Stomatology, Affiliated Hospital of Jining Medical University, from September 2012 to October 2015 were recruited, and all patients had healthy, well-developed, and untreated bilateral permanent mandibular first molars with normal appearance. Subsequently, the three-dimensional reconstruction based on cone-beam CT data was performed using Planmeca Romexis software to observe the variations in the root and root canal system of permanent mandibular first molars in the Han population of southwest Shandong Province. RESULTS AND CONCLUSION: Among 1312 permanent mandibular first molars, the incidence of permanent mandibular first molars with three roots was 70.66% (927/1312); the majority of root canal variations involved two roots and three root canals, accounting for 48.09% (631/1312). The incidence of distal root was 35.37% (232/656), the incidence of distal root was 29.34% (385/1312) in total teeth, and the incidence of distal root bilaterally was 68.95% (153/232). There was a significantly increased incidence of distal root on the right side than on the left side (P < 0.05), and the incidence in the male was significantly higher than that in the female (P < 0.05). These results suggest that most of Han populations in southwest Shandong Province have permanent mandibular first molars with two roots, and the root canal variations mainly involve two roots and three root canals, with the high incidence of distal root. Moreover, cone-beam CT is available for detecting the variation in roots and root canal system, which can provide references for root canal treatment.
