Objective To study the effect of modified sensorimotor training (SMT) method on standing ba- lance of the stroke patients during their recovery stage. Methods Sixty stroke patients at recovery stage were ran- domly divided into an intervention group and a control group. The intervention group was trained by modified SMT method which combined Thera-band with partial body weight support (PBWS) system, while the control group was trained only with their standing balance in the parallel bars based on the neurodevelopment therapy (NDT) method. Both groups were given the same medications as well as physical therapy, acupuncture and OT. The patients in the two groups practiced standing balance in front of a mirror daily, 40 minutes every day and 6 days every week for 4 weeks. The balance abilities of patients were evaluated by Berg balance scale (BBS) , and their lower extremity func- tions were assessed by simplification Fugl-Meyer assessment (FMA). Results After training, both groups showed significant improvement in BBS and FMA ( P

To study in vitro anti-influenza viral activities of Chinese traditional patent medicines for influenza prevention and treatment, neuraminidase (NA) activity assay was used to examine NA inhibitory activity of 33 Chinese traditional patent medicines through fluorimetric assay, and influenza virus induced cytopathic effect (CPE) inhibition assay was used to verify their anti-influenza viral activities in vitro. The assay results showed that most liquid preparations displayed relatively high NA inhibitory activities, such as Shuanghuanglian oral liquid, Qingkailing oral liquid, Qingre Jiedu oral liquid, and Reduning injection. Among liquid preparations, Shuanghuanglian oral liquid not only displayed the highest NA inhibitory effect, but also exhibited obvious in vitro anti-viral activity in CPE experiment. Among solid preparations, Shuanghuanglian powder for injection showed the highest activity on NA inhibition, and Fufang Yuxingcao tablet showed relatively strong anti-influenza viral activity in CPE cells. From the results, it can be concluded that most Chinese traditional patent medicines possessed NA inhibitory activity, but only a few of them displayed significant in vitro anti-influenza viral activities. These results will provide important information for the isolation of active constituents, and for the clinical uses of Chinese traditional patent medicines for influenza treatment and prevention.

Objective To study the effects of different anesthetic methods on stress response in patients during laparoscopic hysterectomy. Methods 45 patients scheduled for laparoscopic hysterectomy were randomly divided into three groups: group A (n = 15) , group B( n = 15) and group C (n = 15). blood samples was taken from patients in each group before anaesthesia, at 10 min and 40 min after pneumoperitomeum with CO_2 , 10 min after operation, to determine the glucose (BG) , catecholamine ( CA ) , C - response protein (CRP) and interleukins -6( IL -6). The changes of MAP ,HR,P_(ET)CO_2 and SpO_2 were also recorded. Results After anesthesia, the MAP, HR significantly decreased in group A (P 0.05 ). Conclusion Combined general epidural anesthesia can effectively inhibit the stress response in patients undergoing laparoscopic hysterectomy.

ObjectiveTo investigate the characteristics of left ventricular structural damage in patients with primary aldosteronism(PA).MethodsA total of 438 inpatients with hypertension from January 2007 to June 2010 were screened for PA,and diagnosis was made in 213 PA patients and 225 patients with essential hypertension (EH).The left ventricular structure of all subjects was evaluated according to the results of echocardiographic measurements.Results The duration of hypertension and plasma aldosterone level in patients with PA were significantly higher (P＜ 0.01 ),while the serum potassium and plasma renin activity were significantly lower (P＜0.01 ) than those in patients with EH.The interventricular septum thickness,left ventricular end-diastolic dimension,left ventricular mass index (LVMI),left ventricular end-diastolic volume,and stroke volume in patients with PA were significantly higher than those in EH patients( P＜0.01 ) after the duration of hypertension was corrected.In patients with PA,the prevalence of left ventricular hypertrophy (LVH) was higher than that in EH patients ( 53.1％ vs 33.8 ％,x2 =16.57,P ＜ 0.01 ). Normal left ventricular geometry ( NG ),concentric remodeling ( CCR ),concentric hypertrophy( CCH),and eccentric hypertrophy (ECH) were found respectively in 24.9％,22.1％,22.1％,and 30.9％ of patients with PA.Multiple stepwise regression analysis showed that the seated plasma aldosterone level (β=0.43,P ＜ 0.01 ) and systolic blood pressure (β =0.45,P ＜ 0.01 ) were the main factors that influenced LVMI.The course was the main parameter that influenced relative wall thickness(β=0.011,P＜0.05 ).Conclusion The prevalence of LVH is higher in patients with PA than that in EH patients.The eccentric hypertrophy is the most common left ventricular geometrical pattern in patients with PA.

Objective To evaluate the efficacy of siege scheme of TCM for acute cerebral infarction bowel and visceral strike (block pattern). Methods Totally 110 patients were randomly divided into TCM siege scheme group (55 cases) and control group (55 cases) by randomized parallel controlled study with foresight and multicenter. The control group was treated with the standardized treatment, and TCM siege scheme group was treated with TCM siege scheme, including mild hypothermia TCM pillow therapy, TCM rectal enema, and other multiple treatments based on the standardized treatment. The Glasgow Coma Scale (GCS), the time of pulling out urine tube and nasal feeding tube, and the number of tracheotomy caused by illness changes of the two groups were compared. Results The baseline data of two groups have good comparability (P>0.05). On 10, 15 d of treatment, the number of lucid people in the TCM siege scheme group was significantly more than that in the control group (P<0.05). Compared with the control group, treatment group had less number of tracheotomy, and shorter time of success pulling out urine tube and nasogastric feeding tube (P<0.05). Conclusion TCM siege scheme can improve the consciousness of ischemic stroke in patients with acute cerebral infarction bowel and visceral strike, reduce complications, shows shorter successful pull urine tube and nasogastric feeding, and provides guarantee conditions for further rehabilitation treatment.

Objective To investigate the feasibility, safety and efficacy of transarterial embolization with low concentration of n-butyl cyanoacrylate(NBCA) in rabbit VX2 liver tumor models. MethodsTwenty-four rabbits were implanted with VX2 hepatic tumors into the left hepatic lobes, and were scanned with CT to measure the volume of the tumor after 14 days. They were randomly divided into three groups with 8 rabbits assigned to each group. Transarterial embolization was conducted with physiological saline in control group A, with pure Lipiodol in group B, with 2.5% NBCA in group C. Hepatic toxicity was evaluated by blood biochemical analysis of the plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST). One week later, the volumes of the tumors were measured by CT again. Tumor growth rate was the ratio of tumor's volume at 7th day after embolization to the tumors' volume before embolization. The survival periods of the rabbits of the three groups after treatment were also recorded. The data of ALT and AST mean values from each group were analyzed with repeated measurement analysis of variance (ANOVA). Tumor growth rates and survival periods were analyzed by using one-way ANOVA. Results All animal models were successfully established and underwent interventional catheterization. Both ALT and AST mean values of the rabbits in group A, B and C at each time point before and after embolization were significantly different (ALT F=10.508, 16.443, 19.828, respectively; AST F=23.696, 23.334, 15.594, respectively)(P＜0.05). ALT in group A, B, C were (49.4±13.5), (115.2±48.8), (124.7±49.4)U/L, while AST in group A, B, C were (52.3±12.0), (128.3±50.1), (137.0±66.9)U/L 4 days after embolization. The ALT and AST mean values were significantly elevated 4 days after embolization in group B and group C compared with those before embolization and those of group A 4 days after treatment(P＜0.05). However, the ALT and AST mean values showed no statistically significant difference in all the groups before embolization and 7 days after embolization. On the other hand, the growth rates of the tumors differed significantly among the three groups(F=110.865, P=0.000). The group C showed significantly lower tumor growth rate (0.839±0.144)% than the group A(2.978±0.547)%(P=0.000), but no significantly different tumor growth rate compared with group B(0.871±0.0725)%( P=0.845). Consequently, the survival period of the animals in group C(38.9±4.0) days was significantly longer than that in group A(32.1±3.1)days (P=0.006), while it was not significantly different from that in group B(36.9±4.8)days(P=0.366). ConclusionsTransarterial embolization with low concentration of NBCA was feasible and safe. It could be a new option of treatment for HCC and might have potential further clinical value.

One hundred and fifty-six patients with primary aldosteronism(PA)and 189 patients with essential hypertension (EH) were included in this study.The value of estimate glomerular filtration rate (eGFR) was calculated by MDRD equation.The plasma levels of aldosterone,triglycerides,creatinine and fasting glucose were measured.The plasma creatine,24 hour urine albumin excretion in PA patients were higher and eGFR and plasma aldosterone were lower than those in EH patients ( all P ＜ 0.01 ).Multiple regression analysis revealed that the plasma concentrations of aldosterone ( P =0.003 ) and creatinine ( P =0.001 ) were independent predictors of eGFR.

Objective To explore an effective mode for the prevention and control of hypertension in agricultural and pastoral areas in Xinjiang by comparing the effect of mode A with that of B in blood pressure-lowering treatment. Methods 1445 patients with hypertension in agricultural and pastoral areas were included in this study. They voluntarily received mode A or B blood pressure-lowering treatment. The changes in heart rate , blood pressure, lipid, and glucose, and the incidences of cardiovascular and cerebrovascular events and adverse events were noted;and the effect of modes A and B was compared. Results 87.07%of the patients chose mode A group, while 12.93%chose mode B. The rate of pressure control was 70.71%in mode A group and 68.75%in mode B group , with no significant statistical difference (P>0.05). In 12th month of treatment, the decreased level of systolic pressure was (19.09 ± 20.33)mmHg in the group with mode A and (14.14 ± 17.85) mmHg in the group with mode B, showing a significant statistical difference between the two groups (P=0.047); and the declined level of diastolic pressure was (11.17 ± 13.23)mmHg and (8.17 ± 11.17) mmHg, respectively, with no significant statistical difference. Conclusion Mode A blood pressure-lowering treatment can effectively control blood pressure in hypertensive patients living in agricultural and pastoral areas in Xinjiang.
