[ABSTRACT]AIM:TodeterminetheeffectsofShensongyangxincapsule(SSYX)ontheventricularelectrical properties, structural remodeling and cardiac function in the rats with diabetes mellitus (DM).METHODS:Male SD rats (n=45) were randomly divided into control group (n=15), DM group (n=15) and SSYX group (n=15).The rats in DM group and SSYX group were injected with streptozotocin (60 mg/kg, ip), while the rats in control group were given normal saline (1 mL/kg, ip).The blood samples were collected 72 h after treatment for determining the blood glucose lev-els in DM group and SSYX group .The model rats in SSYX group were administered with SSYX (1 g· kg-1 · d-1 , ig) for 6 weeks, while the other rats received normal saline (2 mL· kg-1· d-1, ig).The echocardiography was used to assess the cardiac function , and the lead II electrocardiogram was also recorded in all the animals .The radioimmunoassay and Masson trichrome staining were used to measure the plasma levels of endothelin -1 (ET-1) and the collagen deposition in the ventricles, respectively.A whole Langendorff-perfused heart model was used to conduct the electrophysiologic study .The monophasic action potential ( MAP) and the ventricular effective refractory period ( VERP) were recorded in the left anteri-or free wall ( LAF) , and the burst pacing was used to induce ventricular arrhythmia ( VA) .RESULTS: Compared with control group, the VERP, action potential duration (APD), QT interval, incidence of VA, degree of myocardial fibrosis and plasma level of ET-1 were increased , while the cardiac function was declined in DM group .Compared with DM group , the VERP, APD, QT interval, incidence of VA, degree of myocardial fibrosis and plasma level of ET-1 were all de-creased, while the cardiac function was improved in SSYX group .CONCLUSION: SSYX attenuates the electrical and structural remodeling and improves the cardiac function in DM rats .

Objective To investigate the influence and the clinical significance of interleukin-2 (IL-2) on T lymphocyte subgroup after chemotherapy in acute myeloid leukemia patients. Methods Fiftyfour acute myeloid leukemia patients were divided into treatment group (chemotherapy combined with IL-2,28 cases) and control group (pure chemotherapy,26 cases) by radom digits table. In treatment group, IL-2400 000 U was dripped after chemotherapy for 14 days. Then the T lymphocyte subgroup change before and after treatment was examined. Results After 14 days' treatment, the levels of CD3 (0.6026±0.2275 ),CD4(0.4972±0.1224),CD56(0.3016±0.1053 ) in treatment group were significantly higher than those before treatment(0.3926±0.2010,0.2264±0.1190,0.1729±0.1226) and in control group (0.4352±0.1930,0.2738±0.1362,0.1937±0.1268)(P< 0.05). Conclusion IL-2 treatment can obviously raise the levels of T lymphocyte subgroup and can raise the immunologic function.

Objective To observe the effect of Huangxiong Kangshuan capsule on serum high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) levels in patients with acute cerebral infarction. Methods Ninety-two patients with acute cerebral infarction admitted to the First Affiliated Hospital of Anhui University of Traditional Chinese Medicinefrom July 2013 to December 2016 were enrolled, and they were divided into an observation group (47 cases) and a control group (45 cases) by random number table. The control group was given conventional treatment of ischemic cerebrovascular disease, while the observation group was additionally treated by Huangxiong Kangshuan capsule orally taken, once 3 tablets, 3 times a day, on the basis of routine treatment; the duration of treatment was 2 weeks in both groups. After 2 weeks of treatment, the clinical effects of the two groups and the changes of serum hs-CRP and IL-6 levels were observed.Results After treatment, the levels of serum hs-CRP and IL-6 were decreased significantly compared with those before treatment in the two groups [observation group: hs-CRP (mg/L) was 6.18±2.17 vs. 14.11±3.01, IL-6 (ng/L): 28.10±11.47 vs. 120.83±24.51; control group: hs-CRP (mg/L) was 8.89±2.46 vs. 13.97±2.69, IL-6 (ng/L) was 49.48±16.43 vs. 115.25±24.05], and the degree of decline in the observation group was more significant than that in the control group [hs-CRP (mg/L): 6.18±2.17 vs. 8.89±2.46, IL-6 (ng/L): 28.10±11.47 vs. 49.48±16.43, bothP < 0.01]; the total effective rate of the observation group was significantly higher than that of the control group [87.2% (41/47) vs. 71.1% (32/45),P < 0.05]. Conclusion Huangxiong Kangshuan capsule can decrease the serum hs-CRP and IL-6 levels in patients with acute cerebral infarction, and has a role in brain protection and nerve function defect improvement.

Objective To observe the effect of core stability training combined with eye acupuncture on motor function in patients with hemiplegia after stroke.Methods Eighty patients with hemiplegia after stroke were randomly divided into a treatment group and a control group (40 cases in each).Both groups were given regular rehabilitation training, but the patients in the treatment group also were taught core stability training of their waist and abdominal muscle groups, their shoulder muscles, trunk and pelvis.They were also given eye acupuncture.A trunk control test (TCT) , Berg's balance scale (BBS), the modified Barthel index (MBI), functional ambulation categories (FACs) and the Fugl Meyer assessment scale (FMA) were used to assess motor function before and after treatment.Results At the end of 6 weeks of treatment, all of the measurements in both groups had significantly improved.The average TCT, BBS, MBI, FMA, and FAC scores of the treatment group significantly exceeded those of the control group.Conclusions Core stability training and eye acupuncture together can significantly improve the motor function of hemiplegic stroke survivors.The combination therapy is worthy of clinical popularization and application.

Objective To explore the neuroprotective effect of cyclosporine A against cerebral ischemia in a rat model of cerebral ischemia reperfusion. Methods Fifty-two adult male SD rats, weighted 250-280 gram, were randomly divided into three groups: the sham group (group A, n=6), PBS control group (group B, n=23) and cyclosporine A group (group C, n=23). Group C received hypodermic injection of cyclosporine A 10mg/kg daily after surgery and group B re?ceived equal volume of PBS instead. Modified Neurological Severity(mNss)scores were used to assess the neurological deficits at 3, 7, 14, 21 and 30 days following cerebral ischemia. The infarct volume were measured 3 days after reperfu?sion. The neurons, reactive microglia and astrocytes around the infract area were detected by immunofluorescence at 3 and 30 days after surgery. Results Modified Neurological Severity scores were significantly lower in group C than group B at the third(P=0.003),seventh (P=0.011),Fourteenth (P=0.000),twenty-first (P=0.003) and thirtieth (P=0.004) days after surgery. cyclosporine A reduced infarct volume, reactive microglia and astrocytes while increased survived neurons (P<0.001) in ischemic penumbra 3 and 30 days after reperfusion (all P<0.001). Conclusion Continuous injection of cyclosporine A not only protects neurons against ischemia damage but also improves neurological functional recovery af?ter acute stage of damage, possibly through reduction of reactive microglia cells and proliferation of astrocytes.

Objective To investigate the significance and mechanism of intracerebroventricular injection viper venom nerve growth factor (Vngf) in rat neural plasticity after cerebral ischemia reperfusion injury.Methods Ninety Wistar male rats were randomly assigned into Vngf-25 U group (n = 18), Vngf-50 U group (n = 18), Vngf-100 U group (n = 18), ischemia reperfusion group (n = 18) and sham operated group.The expression of candidate plasticity-related gene 15(cpg-15) Mrna and nuclear factor of kappa B ( NF-Κb ) Mrna in rat brain tissues which were collection at 2,7,14 days after surgery were evaluated by the real time PCR.Results The expression of cpg-15 Mrna and NF-Κb Mrna began to increase after surgery( the F value of cpg-15:70.43, 34.11, 31.89, the F value of NF-Κb: 27.47, 34.56, 31.89,P＜0.01).At the same time, expression of cpg-15 Mrna and NF-Κb Mrna in the Vngf groups was significantly different from the I/R group and the sham operated group (the F value of cpg-15:48.18, 55.93, 78.43, the F value of NF-Κb: 45.92, 55.72, 50.49, P ＜0.01).The more Vngf were injected, the more cpg-15 Mrna and NF-Κb Mrna were expressed in Vngf groups.Conclusions The Vngf could accelerate neural plasticity and restore neurofunctional defect through up-regulated the expression of cpg-15 and NF-Κb.

Objective To evaluate the relationship between post-stroke urinary incontinence(UI)and 1 year stroke outcomes.Methods One hundred and thirty consecutive cerebral stroke survivors were classified into 2 groups according to their incontinence status at 1 to 10 d after onset.The patients'baseline characteristics,1 year mortality rate,abilities in the activities of daily living(ADL)and Modified Rankin Scale(mRS)scores were compared.Multivariate analysis was applied to highlight UI risk factors and correlations between UI and 1 year outcomes.Results Total anterior circulation syndrome(TACS)numbers and National Institutes of Health stroke assessment (NIHSS)scores in the UI group exceeded significantly those in the non-UI group,and both were significantly associated with initial UI.The 1 year mortality rate,patients'ADL dependence and mRS scores in the UI group exceeded those in the non-UI group significantly.Initial UI was also significantly associated with the 1 year outcome independently,as well as with age＞75 years,Oxfordshire Community Stroke Project(OCSP)classification and initial NIHSS score.Conclusion UI is common in the patients with TACS and higher initial NIHSS scores.Initial UI predicts a poor 1 year outcome,SO treatment should be strengthened.
