Cardiovascular diseases, like coronary heart disease and myocardial infarction, are the most common cause of death worldwide. Chinese medicines have demonstrated rich cardioprotective activities for clinical applications. Salvia miltiorrhiza, a very important component of traditional Chinese medicine, can promote blood circulation and relieve blood stasis. Salvia miltiorrhiza is widely used in treatment of cardiovascular and cerebrovascular disease such as coronary heart disease and cerebral infarction ( CI). Tanshinone II(A), the major lipophilic components extracted from the root of S. miltiorrhiza, possesses anti-atherosclerosis, anti-cardiac hypertrophy, anti-oxidant, anti-arrhythmia and so on. This paper discusses current research status of tanshinone II(A) in cardioprotective effects.

OBJECTIVETo seek for a good therapy for childhood hyperkinetic syndrome (CHS).

METHODSTwo hundred and ten patients of CHS were randomly divided into three groups, the Yizhi mixture (YZM) group, the Ritalin group and the combined treated group, 70 in each group. They were treated with YZM alone, Ritalin alone and combined YZM and Ritalin respectively for 12 weeks. The effect was assessed by Conners' questionnaire for hyperkinetic scoring, Achenbach's questionnaire for behavior estimation, clinical general image questionnaire and Tess's questionnaire before and after treatment.

RESULTSThe total effective rate in the YZM group, Ritalin group and combined treated group was 75.7%, 74.2% and 82.8% respectively, and the markedly effective rate in the three groups was 44.3%, 45.7% and 80.0% respectively. By chi 2 test, comparison among the three groups showed that the difference of the total effective rate was insignificant, while that of the markedly effective rate was significant (chi 2 = 23.31, P < 0.01). Further analysis conducted by partitioning method to make comparison between each two groups showed that the markedly effective rate was significantly higher in the combined treated group than that in the YZM group (chi 2 = 18.98, P < 0.01) and in the Ritalin group (chi 2 = 17.62, P < 0.01). The low hyperkinetic score, behavior score, achievement of Chinese and mathematics in the CHS patients were improved after treatment, the improvements were significantly higher in the combined treated group than those in the other two groups (P < 0.05, by q-test). Moreover, the soft nerve signs and abnormal encephalogram were significantly improved in the combined treated and the YZM groups, and the side-effect occurred in the two groups was less than that in the Ritalin group (P < 0.01).

CONCLUSIONThe therapeutic effect of combined treatment of YZM and Ritalin was better than that of YZM or Ritalin alone.

BACKGROUND: Animal experiments showed that recruitment maneuver (RM) and protective ventilation strategy of the lung could improve oxygenation and reduce extravascular lung water. This study was to investigate the effects of RM on respiratory mechanics and extravascular lung water index ( EVLWI) in patients with acute respiratory distress syndrome (ARDS). METHODS: Thirty patients with ARDS were randomized into a RM group and a non-RM group. In the RM group, after basic mechanical ventilation stabilized for 30 minutes, RM was performed and repeated once every 12 hours for 3 days. In the non-RM group, lung protective strategy was conducted without RM. Oxygenation index (PaO2/FiO2), peak inspiratory pressure (PIP), Plateau pressure (Pplat), static pulmonary compliance (Cst) and EVLWI of patients before treatment and at 12, 24, 48, 72 hours after the treatment were measured and compared between the groups. Hemodynamic changes were observed before and after RM. One-way ANOVA, Student's t test and Fisher's exact test were used to process the data. RESULTS: The levels of PaO2/FiO2 and Cst increased after treatment in the two groups, but they were higher in the RM group than in the non-RM group (P<0.05). The PIP and Pplat decreased after treatment in the two groups, but they were lower in the RM group than in the non-RM group (P<0.05). The EVLWI in the two groups showed downward trend after treatment (P<0.05), and the differences were signifcant at all time points (P<0.01); the EVLWI in the RM group was lower than that in the non-RM group at 12, 24, 48 and 72 hours (P<0.05 or P<0.01). Compared with pre-RM, hemodynamics changes during RM were significantly different (P<0.01); compared with pre-RM, the changes were not significantly different at 120 seconds after the end of RM (P>0.05). CONCLUSIONS: RM could reduce EVLWI, increase oxygenation and lung compliance. The effect of RM on hemodynamics was transient.

AIM: To explore the role of extracellular signal-regulated kinases ERK1/2-STAT3 pathway in adaptive cytoprotection induced by H2O2 preconditioning in PC12 cells.METHODS: In PC12 cells,the experimental model of cytoprotection by H2O2 preconditioning against oxidative stress-induced injury was set up.The morphological changes in the apoptotic cells were observed by using of chromatin dye Hoechst 33258.The percent of apoptotic cells was determined by flow cytometry(FCM) with propidium iodide staining.The levels of p-ERK1/2 and p-STAT3 expression were detected by Western blotting assay.RESULTS: Preconditioning with H2O2 at concentration of 100 ?mol/L for 90 min obviously inhibited apoptosis induced by 300 ?mol/L H2O2,and both ERK1/2 and STAT3 were activated.UO126(10 ?mol/L,an inhibitor of ERK1/2) or AG-490(10?mol/L,an inhibitor of JAK2) significantly blocked the cytoprotection effect of H2O2 preconditioning.Moreover,UO126(10 ?mol/L) also markedly inhibited the up-regulation of p-STAT3 expression by H2O2 preconditioning.CONCLUSION: H2O2 preconditioning activates ERK1/2-STAT3 signal pathway,which may be one of the mechanisms underlying H2O2 preconditioning-induced cytoprotection.

Conclusion The test and reference preparation of cefdinir capsules are bioequivalent.

BACKGROUND:This systematic review aims to investigate the prediction value of diffusion tensor imaging for motor function recovery of ischemic stroke patients. METHODS:Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2016, Issue 9), PubMed, Embase, Clarivate Analytics, Scopus, CINAHL, Chinese Biomedical Literature Database, China National Knowledge Infrastructure and Google Scholar were searched for either motor recovery or corticospinal tract integrity by diffusion tensor imaging in different stroke phase from January 1, 1970, to October 31, 2016. The study design and participants were subjected to metrological analysis. Correlation coefficient (r) was used for evaluating the relationship between fractional anisotropy (FA) and motor function outcome. Correlation coefficient values were extracted from each study, and 95％ confidence intervals (CIs) were calculated by Fisher's z transformation. Meta-analysis was conducted by STATA software. RESULTS:Fifteen studies with a total of 414 patients were included. Meta-analysis showed that FA in the subacute phase had the significant correlation with motor function outcome (ES=0.75, 95％CI 0.62-0.87), which showed moderate quality based on GRADE system. The weight correlation coefficient revealed that an effect size (ES) of FA in acute phase and chronic phase was 0.51 (95％CI 0.33-0.68) and 0.62 (95％CI 0.47-0.77) respectively. CONCLUSION:This meta-analysis reveals that FA in the subacute phase after ischemic stroke is a good predictor for functional motor recovery, which shows moderate quality based on the GRADE system.
