OBJECTIVETo explore the effect of Chinese drugs for activating blood circulation and removing blood stasis (CDABCRBS) on carotid atherosclerotic plaque and long-term ischemic cerebrovascular events.

METHODSBy using open and control method, effect of 4 groups of platelet antagonists, platelet antagonists + CDABCRBS, platelet antagonists +atorvastatin, platelet antagonists +atorvastatin +CDABCRBS on carotid atherosclerotic plaque and long-term ischemic cerebrovascular events of 90 cerebral infarction patients were analyzed.

RESULTSThrough survival analysis, there was no statistical difference in the effect of the 4 interventions on the variation of carotid stenosis rates or ischemic cerebrovascular events (P > 0.05). The occurrence of ischemic cerebrovascular events could be postponed by about 4 months in those treated with platelet antagonists + CDABCRBS and platelet antagonists + atorvastatin +CDABCRBS. By multivariate Logistic analysis, age, hypertension, and clopidogrel were associated with stenosis of extracranial carotid arteries (P <0.05). Age, diabetes, aspirin, clopidogrel, CDABCRBS were correlated with cerebrovascular accidents (P < 0.05).

CONCLUSIONSWhether or not accompanied with hypertension is an influential factor for carotid stenosis, but it does not affect the occurrence of ischemic cerebrovascular events. CDABCRBS could effectively prolong the occurrence time of ischemic cerebrovascular events.

Objective To study the curative effect of praziquantel against juveniles of Paragonimus westermani and the dynamic changes of T lymphocytes and their subpopulations in infected mice after treatment. Methods Mice infected with metacercariae of P. westermani were treated with praziquantel 10 days after infection for examining the curative effect. Results Mice infected orally each with 30 metacereariae of F. westermani were treated with praziquantel at doses of 400,500 and 600 mg/(kg?d) respectively for 3 d, the juvenile reduction rates were 71.01 % ? 10.38% ,82.29% ? 7.92% and 95.83% ? 3.24% respectively; when the mice were infected with 80 metacercariae and treated with a dose of praziquantel 600 mg/(kg?d) for 3 d, the worm reduction rate was 84.49% ?10.91%. T lymphocytes and their subpopulations began to increase at 1 wk and returned to normal at 8 wk after praziquantel treatment. Conclusion The efficacy of praziquantel against juvenile P. westermani was poorer than that against adult worms ; the efficacy was relevant to the drug dosage and the number of metacercariae infected. The T lymphocytes and their subpopulations may be regarded as an index for curative effect.

Objective B-type natriuretic peptide(BNP) have been used widely in the diagnosis and prognosis of cardiogenic diseases, but the association between BNP concentrations and non-cardiogenic critical illness is unknown. Our study aims at investigating the role of natriuretic peptide testing for predicting 28-day mortality of non-cardiogenic critically ill patients in emergency department (ED). Methods A total of 255 non-cardiogenic critically ill patients treated in the emergency department were prospectively enrolled and a sample of blood was obtained for BNP measurement from each patient. A variety of clinical and laboratory variables were recorded. After 28 days, the vital status of each patient was ascertained and the association between BNP values at presentation and mortality was assessed. Results 71 patients died during the 28-day observation period. Median BNP concentrations at presentation among decedents were significantly higher than those of survivors (326. 0 ng/L versus 50. 9 ng/L,P <0. 001). The optimal BNP cut point for predicting 28-day mortality was 114. 0 ng/L. In a multivariate analysis (Cox-regression), a BNP concentration greater than 114. 0 ng/L(RR 7. 268, 95% CI 3. 864-13. 672) and an Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores greater than 20 (RR 3. 330, 95% CI 1. 815-6. 109)were the independent predictors of the 28-day mortality. BNP concentration alone had an area under the receiver operating characteristic curve (AUC) of 0. 825 for predicting mortality. Conclusions BNP concentrations at presentation are strong predictor of 28-day mortality in patients with non-cardiogenic critically ill patients in ED, which is better than Rapid Acute Physiology Score (RAPS) , Rapid Emergency Medicine Score (REMS) and APACHE Ⅱ score.

The paper suggests appling various teaching methods comprehensively to raise the students' interest and activate the class atmosphere to improve the biochemistry teaching effect on the basis of teaching materials and the level of the students during the teaching practice.

Combining the experiment teaching innovation in our college,we carried on beneficial quest to the teaching mode of the biochemistry experiment.During the practice of the designing experiment,we not only pay attention to cultivating students' creation ability,but also lay emphasis on cultivation of their autonomy ability.which is very important to improve the students,early scientific research abilities or clinical practice abilities and so on.

Objective To investigate the effect of different antiplatelet or anticoagulation therapy on postoperative pocket hematoma after electrophysiological devices placements (EPD). Methods The clinic data of 410 patients who took anti-platelet or anticoagulation therapy and needed to be implanted EPD from February 2012 to February 2015 were selected. According to the type of therapy, patients were divided into 4 groups:dual anti-platelet drug (DAP) treatment group (DAP group, 114 cases), low-molecular-weight heparin (LMWH) bridging treatment group (LMWH group, 98 cases), aspirin (ASA) alone group (ASA group, 94 cases) and warfarin group (104 cases). The incidence of pocket hematoma after electrophysiological devices placements was observed. The risk factors of pocket hematoma were analyzed. Results The incidence of pocket hematoma was higher in LMWH group than that in the other 3 groups: 18.4% (18/98) vs. 4.4% (5/114), 3.2% (3/94) and 2.9% (3/104), and there was statistical difference (P<0.05). But there were no significant differences in the incidence of pocket hematoma among DAP group, ASA group and warfarin group (P>0.05). The multiple Logistic regression analysis revealed that LMWH bridging therapy was an independent risk factor for the development of pocket hematoma (OR=7.105, 95%CI 1.872-17.283). Conclusions LMWH bridging therapy can increase the risk of development of pocket hematomas after electrophysiological devices placement.

The ion beam bioengineering study articles for 1994 -2003 years were retrieved, the research material and the level of the research, magazine, the ion source and the fund source were analysed and counted. The results indicate that the ion beam bioengineering of China get a fast development under the support of the nation and the local government and college. The development in the field of microbe is the fastest. in 21st century, the local government and colleges gradually enlarge the support of the ion beam bioengineering, some articles are under the support of enterprise researcher and fund. The contents of these articles mainly about application study. After analysing the data, the future of ion beam bioengineering of China was forecasted.
