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 predictive value of plasma lipoprotein associated phospholipase A 2 (Lp-PLA2 ) in cere-bral infarction(CI) after transient cerebral ischemia attack (TIA).Methods Plasma Lp-PLA2 level was detected in 112 TIA pa-tients ,and the incidence rate of CI was observed on 7 ,30 ,90 d after TIA.Then the grouping was performed according to the Lp-PLA2 level ,and the predictive value of Lp-PLA2 in the risk of CI occurrence after TIA was evaluated.Results Among 112 patients with TIA ,27 cases (24.1% ) developed CI within 90 d;there were 17 cases(63.0% ) of CI after TIA in the Lp-PLA2 >207 μg/L group ,which were significantly higher than that in the 175-207 μg/L group and <175 μg/L group (P<0.05);moreover the CI occurrence in TIA patients was mainly concentrated within 7 d after onset ;the patients of Lp-PLA2 ≥175μg/L were mainly distrib-uted in the moderate and high risk groups of ABCD2 score system ;in ROC curve of Lp-PLA2 for predicting CI after TIA ,with Lp-PLA2 ≥194 μg/L as the diagnostic critical point ,the sensitivity was 0.730 and specificity was 0.680.Conclusion Lp-PLA2 may be an effective risk predictive indicator of CI occurrence after TIA ,and can improve the adverse outcome of TIA patients.

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 early intervention effect in autism spectrum disorders children with dysaudia. METHODS Three cases of child with language barrier were diagnosed with dysaudia by acoustic impedance test, distortion otoacoustic emission (DPOAE) and short sound auditory brainstem response test (ABR). They were diagnosed with autism pectrum disorders through further test. They were matched with hearing aid, and took speech rehabilitation training, followed-up one year to observe the language communication effect. RESULTS After one year of treatment with hearing aid, both CAP and SIR score increased. CONCLUSION Autism spectrum disorders children with dysaudia can get better language exchange by early intervention with hearing aid and speech rehabilitation training.

BACKGROUND:Metabolic characteristics of the 800 meters race is not very clear, which creates a lot of obstacles for the exercise training of 800 meters race. OBJECTIVE: To investigate the characteristics of material and energy metabolism of 800 meters race, to improve the scientific training of the 800 meters race and to verify the feasibility of nuclear magnetic resonance-based urine metabonomics in sports training monitoring. METHODS: Seven middle distance athletes were subject to an 800 meters race at ultimate intensity, and their urine metabonomics analysis was conducted in combination with the Human Metabolism Database and other databases before and after exercise. RESULTS AND CONCLUSION:OPLS-DA model showed that the metabolic samples before and after movement presented the cluster-like distribution. The change was mainly caused by the folowing metabolites, including leucine, lactic acid, creatinine, succinic acid, hypoxanthine, and adenosine. Through the analysis we could infer that the 800 meters race is a sport event mainly dependent on glycolysis for energy supply, working together with raw phosphate and aerobic oxidation for energy supply. The amino acid metabolism and methane metabolism of the athletes were more vigorous after 800 meters running, and moreover, there were certain oxidative stress during the 800 meters race. These findings indicate that nuclear magnetic resonance-based urine metabonomics takes the advantages of invasive, high sensitivity, less sample requirement, simple processing.

Objective:To explore the abortion effect and mechanism induced by Chinese herbal medicine rhubarb extract.Methods:The pregnant mice at day 3 of gestation were Drenched by Aqueous extract of rhubarb at different doses (7,5,2.5 g/kg)once per day for five days,and mices in control group were oral administration of same volume of saline.All mices at 12 day of gestation were sacrificed.estradiol and progesterone levels in serum were detected by Radioimmunoassay;Content of IFN-γ, IL-2 and TNF-αin uterine lysates were measured by ELISA, macrophages in endometrium were determined by immunohistochemical method, mast cells in endometrium were tested by Toluidine blue staining, respectively.Results: showed as follows:With increasing dose of rhubarb extract,abortion rate and resorption rate were gradually increased and was 100%abortion in 7g/kg treatment groups.Estrogen and progesterone content showed a downward trend,IFN-γ,IL-2 and TNF-αin uterine lysates and the numbers of macrophages and mast cells were significantly higher in mices Drenched by Aqueous extract of rhubarb than in the control.Conclusion: These results show that rhubarb extract not only interfere stability of pregnancy state in pregnant mices because of its diarrhea,but also can directly affect endometrial environment in early embryonic mice,Resulting in abortion.

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.
