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.

The antitussive activity assay for the root extraction of Disporum cantoniense was carried out with coughing mice induced by ammonia liquor. The results showed that the ethanol and water extractions of D. cantoniense possess strong antitussive activity, and the high dose of the former was better than positive control, and then the constituents of the ethanol extraction were separated and purified by various modern chromatographic techniques. Their structures were identified by physico-chemical properties and spectroscopic data. As a result, eight compounds were isolated and identified as stigmast-4-en-3-one(1), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol(2), obtucarbamate A(3), obtucarbamate B(4), neotigogenin(5), azo-2, 2'-bis[Z-(2,3-dihydroxy-4-methyl-5-methoxy) phenyl ethylene] (6),dimethyl {[carbonylbis (azanediyl)] bis( 2-methyl-5, 1-phenylene) j dicarbamate (7) , and quercetin-3-O-pB-D-glucopyranoside(8). All compounds were isolated from this plant for the first time, and the result of bioactivity-directed isolation showed that compounds 3, 4, and 6 had obvious effect on antitussive activity, and compound 6 had the same level as positive control.

Objective To investigate the effects of remote ischemic postconditioning (RIPoC) on global cerebral ischemia-reperfusion (I/R) injury in rats.Methods One hundred and twenty-eight male adult SD rats weighing 200-250 g were randomly divided into 4 groups ( n =32 each):sham operation group (group S),group I/R,group I/R + RIPoC and remote I/R group (group RI/R ).Global cerebral I/R was induced by four-vessel occlusion.Group I/R + RIPoC received 3 cycles of 15 min reperfusion followed by 15 min ischemia in bilateral femoral arteries at the beginning of cerebral reperfusion.The rats were sacrificed at 24 and 48 h of cerebral reperfusion,and brains were removed for determination of neuronal apoptosis (by TUNEL method) in hippocampal CA1 region and the parietal cortex,Bcl-2 and Bax expression (by Western blot) in hippocampal CA1 region.The superoxide dismutase (SOD) and catalase (CAT) activity and malondialdehyde (MDA) content in hippocampal CA1 region and the parietal cortex were also measured at 48 h of cerebral reperfusion.Morris water maze task was used to test the learning and memory function at 4 d of cerebral reperfusion,and the rats were sacrificed at 7 d of cerebral reperfusion,and brains were removed for determination of neuronal density in hippocampal CAl region and the parietal cortex.Results Cerebral I/R significantly increased the number of apoptotic neurons and MDA content,upregulated Bcl-2 and Bax expression,decreased neuronal density,SOD and CAT activity and learning and memory function in group I/R as compared with group S.RIPoC significantly attenuated these cerebral I/R-induced changes.Conclusion RIPoC could protect brain against global cerebral I/R-induced injury,and the mechanism may be related to inhibiting lipid peroxidation,regulating the balance between Bcl-2 and Bax and inhibiting apoptosis.

Objective To explore the preventative effect of donor peripheral blood stem cell (PBSC) infusion mobilized by granulocyte colony-stimulating factor (G-CSF) for the relapsing patients with leukemia after haplotype hematopoietic stem cell transplantation ( HSCT) , as well as its therapeutic effect and safety. Methods G-CSF was given at 5-10 μg · kg-1 · d-1 to donor and PBSCs were obtained on day 5 and frozen and allotted for storing. PBSC infusion was given to all the 20 patients on day 90 after HSCT,and the second treatment was given to 4 patients on day 30 after the first infusion. The occurrence of graftversus-host disease ( GVHD) , relapse rate of high risk leukemia and long-term survival were evaluat after PBSC infusion. Results A total of 19 patients had acute GVHD after PBSC infusion for a median of 25 (12-60) months, 4 of them were ≥ degree Ⅲ. The cumulative incidence rate was 22.9%, and all of them accepted PBSC infusion twice. Thirteen patients had assessable chronic GVHD, 10 of them were restricted,and no one died of it. Nine patients died of relapse of leukemia. The remaining 11 patients survived leukemia free, including 4 with chronic myelogenous leukemia, 4 with acute myeloid leukemia (AML) , 1 with lymphoma-leukemia and 2 with myelodysplastic syndrome-AML (MDS-AML). Kaplan-Meier analysis showed the disease free survival rate of 2-year was 52. 5%. Conclusion The prophylactic donor PBSC infusion mobilizing with G-CSF is effective, safe and feasible for the relapse of leukemia.

In this study, the general bacterial probe and specific cellulolytic bacterial probes were used to quantify the bacteria in rumen. The total RNA were extracted and then hybridized with general bacterial probe after a dilution of concentration. The result showed that there was a high correlation between the hybridization signal and the dilution of total bacterial RNA. Based on the result above, the quantities of three cellulolytic bacteria in rumen sample were detected. The comparative RNA percentage of three cellulolytic bacteria to total bacterial RNA were similar to the previous reports. It can be concluded that the quantification of bacteria in rumen could be conducted by this approach, and which could be used in future research.

Objective To investigate the features of chronic prostatitis during puberty(CPP)and the effects of pelvic floor biofeedback therapy.Methods Totally,25 CPP children (mean age,16 years) and 15 children (mean age,16 years) with normal lower urinary tract as controls were included.In CPP group,NIH-CPSI scores were evaluated,expressed prostatic secretions (EPS) were examined,and bacterial culture was done;and CPP patients were categorized based on the definitions of NIH types.In both groups, urodynamic examination was performed,including evaluation of uroflow curve,maximum flow rate (Q_(max)), post-voiding residual urine (PVR),detrusor-sphincter dyssynergia (DSD),maximum detrusor pressure (P_(det,max))and maximum urethral closure pressure (MUCP).CPP patients underwent biofeedback therapy, and 10 weeks later the effects were assessed.Results In CPP group,NIH typing showedⅡ,ⅢA andⅢB in 1,3 and 21 cases,respectively.Before treatment in CPP and control groups,the incidence of staccato voiding (20 cases vs 1 case),DSD (22 cases vs 1 case),Q_(max)(10.7?3.7 vs 15.0?4.3ml/s),PVR (7.7?4.1vs 3.2?2.6ml),P_(det,max)(115.1?33.6vs 76.8?16.6cm H_2O)and MUCP(176.5?45.7 vs 86.2?28.5cm H_2O)all showed significant differences between the 2 groups(P＜0.05).In CPP group,the differences in pain(4.6?2.2 vs 2.1?1.6),urination (7.9?2.0vs 2.2?1.7),life impact (9.4?2.2vs 2.6?2.1)and total scores(22.0?5.2vs 7.0?4.2) of NIH-CPSI and Q_(max)(10.7?3.7 vs 14.9?5.6) between pre-and post-biofeedback were significant (P＜0.05).Conclusions The main type of CPP is categoryⅢB.The primary symptom is voiding disorder,which leads to greater psychological stress in patients.Children with CPP have pelvic floor dysfunctions and multiple abnormal urodynamic param- eters.The short-term effect of biofeedback strategies for CPP is satisfactory.

0.5 cm or beneficial anatomical vari- ations displayed on MRCP,were obviously improved and there were no significantly different among the 4 types hilar eholangiocarcinoma.Conclusion MRCP could accurately make the preoperative diagnosis and type of hilar cholangiocarcinoma; the image of second branch of bile duct and the variation of the confluence of hepatic hilar displayed on MRCP has great clinical significance for operative regimes of hilar cholangiocar- cinoma,especially for typeⅣ.It does benefit not only to improve the resection and radical rate of some hilar cholangiocarcinomas, but also to select suitable method of biliary enteric anastomosis and avoid injuring the bile duct in operation.
