AIM:To evaluate the efficacy of Wuling Capsule(xylaria) in treating senile systolic hypertension. METHODS: Sixty-four patients with senile systolic hypertension were randomly divided into two groups.Both the treated group and the control group were treated with anti-hypertensive for 4 weeks,but the treated group received Wuling Capsule.Therapentic effects were evaluated with HAMA.Noninvasive resting blood pressure was taken every day after treatment,and dynamic blood pressure before and after treatment. RESULTS: HAMA in both groups decreased somewhat but blood pressure in the treated group was lower than that in the control group,remission rate of the treated group was greater than that in the control group.Treatment period of the treated group was shorter than that of the control group. CONCLUSION: Wuling Capsule can relief anxiety in senile hypertension patients,and it can rise the control rate of blood pressure,and also shorten the treatment period.

For understanding the effect of MDG-1, a water-soluble β-D-fructan polysaccharide from Ophiopogon japonicas, on intestinal microecological balance, especially on the changes of lactobacillus, sixty 8-week-old male C57BL/6J mice were given a high-fat diet for six weeks and were also gavaged with saline once a day simultaneously. Then the mice which is below 30 grams or dropped more than 10% through lavage were eliminated and the rest were randomly divided into four groups: diet-induced obese (DIO) model group (n = 12, gavaged with saline), low-dose MDG-1 group (n = 12, gavaged with MDG-1, 75 mg · kg(-1)) , medial-dose MDG- 1 group (n = 12, gavaged with 150 mg · kg(-1)), and high-dose MDG-1 group (n = 12, gavaged with 300 mg · kg(-1)) according to the weight and blood glucose; the model group and MDG-1 group were placed on a high-fat diet while the normal control group (n = 12, gavaged with saline) were kept on a low-fat diet through the experiment. After 12-weeks of treatment, feces samples were collected and cultured for intestinal microecological balance analysis. Then the intestinal probiotics were cultured through traditional methods combined with modified gradient gel electrophoresis (DGGE) method. The changes of lactobacillus in each treatment group were also detected by a statistical analysis of the total number of the intestinal flora. We have established the phylogenetic tree by 16S rDNA sequencing and use some molecular identification methods such as PCR-DGGE to analyse the changes of the dominant bacteria floras, and also get the pure culture. In conclusion, different concentrations of MDG-1 can increase the number of the intestinal probiotics, especially Taiwan lactobacillus and Lactobacillus murinus, and improve their diversity and promote proliferation in a dose-dependent way.

Objective To evaluate the effect of individualized diet nursing on nasogastric gavage-indueced complications after operations on laryngeal cancer? Methods Sixty patients having undergone surgical operation on laryngeal cancer were randomly divided into experiment group and control group in equal number? The control group received nutritional support by conventional enteral nutrition and the experiment group was managed by individualized diet nursing with nasogastric feeding? On days 3 and 10 after operation,the two groups were compared in terms of body constitution,results of experimental tests and complications?Result Compared to the control group,the experiment group showed no significant difference in terms of body constitution and results of experimental tests(P > 0?05)but significantly lower rate of complications on days 3 and 10(P < 0?05)? Conclusion The individualized diet nursing for laryngeal cancer patients may ensure their needs for nutrition,meanwhile reduce the incidences of complications from enteral nutrition,and thus promote their recovery?

The drug release characteristics ofDa Chuanxiong Fang multiunit drug delivery system (DCXFMDDS) in vivo and in vitro were evaluated. Ferulic acid (FA) and senkyunolide I (SI) were used as marker components, which were two of the effective components of Da Chuanxiong Fang. And their contents were determined by HPLC. Drug release characteristics in vitro of DCXFMDDS and Da Chuanxiong pills and pharmacokinetics characteristics of DCXFMDDS and Da Chuanxiong Fang active fraction (DCXFAF) in rats were compared. It was obvious that FA released from the DCXFMDDS in a sustained fashion but SI in a fast fashion both in vitro and in vivo. The releasing process and the releasing mechanism of FA and SI from DCXFMDDS were different, but the AUC value indicated that compared with DCXFAF the extent of absorption of FA and SI from DCXFMDDS was increased. Though from the same multiunit drug delivery system, FA an SI had different drug release characteristics both in vitro and in vivo, and that may be one of the reason why DCXFMDDS has the good properties such as rapid and long-lasting effect and high efficiency.

Objective To explore the effects of extrinsic and intrinsic recognition loading on gait in patients with Parkinson disease.Methods Eight patients with Parkinson disease and six control subjects were instrutted to walk with extrinsic and intrinsic recognition loading respectively.The gait parameters in two conditions were measured with three-dimension motion analysis equipment.FAB scale and Stroop Test were used as the evaluation of executive function.Results The velocity(cm/s),the cadence(step/min),single support and swing phase(%)in the audition stimulates condition in the patients group((113.4±14.32)step/min,(78.90±16.35)cm/s,(40.50±2.58)%,(40.50±2.58)%)were significantly better than those in the calculation condition(respectively(91.27±15.54)step/min,(63.79±21.49)cm/s,(37.95±2.61)%,(37.95±2.61)%).In the calculation condition,the coefficients of variability in stride length,swing and sinfle support phase were significantly higher in the patient group(respectively(6.69±3.99),(8.56±5.69),(8.56±5.69))than in thecontrol group(respectively(3.23±1.34),(5.02±2.54),(5.02±2.54));in the audition condition,except that,the coefficients of variability in step length and velocity also were significantly higher in the patient group(respeetively(11.92±5.86),(6.89±4.98))than the control group(respectively(7.35±3.32),(2.5±1.53)).In the patients group,the score of FAB(15.63±1.51)was lower and error rates of Stroop test(0.087±0.056)was higher than those in the control group(respectively(17.67±0.52),(0.027±0.03))significantly.The error rate of stroop-3 was significantly negative correlated with the gait variables of patient group in the calculation condition.Conclusion The extrinsic audition stimulates has lower effect on the gait of patients of Parkinson's disease than the intrinsic recognition loading.

Objective To investigate the reliability and sensitivity of a three dimensional motion analysis system by using the segmental method.Methods Ten healthy young men participated in this study.They were asked to stand with one leg and with their eyes open and closed,respectively,each lasted for 30 seconds and was re- peated twice.According to the 12-segment rigid body model of the human body,twenty-one infrared light emitting di- ode(1RED)markers were placed over the bony prominences on the proximal and distal ends of each segment,the motion track of the IRED markers was recorded by the three dimensional motion analysis system.The mean sway am- plitude( MSA )and the sway path(SP)of the center of gravity(COG)were calculated.Correlation analysis was used to determine the reliability between the two repetitions.Paired sample t-test was used to determine the sensitivity be- tween the eyes open and closed conditions.Results The correlation coefficients of the MSA of the COG in the eyes open and closed conditions were 0.623 and 0.018,respectively,and the correlation coefficients of the SP of the COG were 0.936 and 0.654,respectively.It was also shown that significant differences existed among the three directions of the MSA of the COG and the SP of the COG.Conclusion Besides the weak reliability of the MSA of COG in the eyes closed condition,the high reliability and sensitivity of the MSA and SP of the COG are found.The segmental method can be used in the scientific study of human balance control.

Pg.The adherence activity of periodontal pathogens to HA was enhanced by Ss and Av.When cultivated with Sm,the adherence activity of Pg was reduced.Periodontal pathogens had no effect on the adherence activity of Sm and Av,and Ss excepted. Conclusion The adherence activity of periodontal pathogens is lower than that of cariogenic bacteria.Periodontal pathogens can utilize early-attached bacteria to become those predominant bacteria in periodontal ecosystem.

Objective To investigate the change of cardiac function in elderly hypertensive patients with heart valve degenerative by echocardiography.Methods A total of 126 cases were divided into a valve disease group and non-valve disease group groups.The parameters of trial size,cardiac function and pulmonary artery pressure were detected.Results Of all 126 cases were the patients with hypertension including 28.6% (36/126) of valve disease group and 71.4% (90/126) of non-valve disease.There were 31 cases with mitral valve disease,22 cases with tricuspid valve disease; 26 cases with aortic valve disease; 36 cases with double or three alvular lesions in valve disease group.There was a significant difference in ventricle size and systolic function among valve disease group and non-valve disease group and control group.But there was no significant difference in thickness of ventricular wall between valve disease group and non-valve disease group.Conclusion The elderly hypertensive patient with valve disease was an independent factor for the development of congestive heart failure.

AIM: To investigate protective effect of N-acetylcysteine (NAC) on liver and lung in mice after hepatic ischemia/reperfusion injury. METHODS: BALB/c mice were used in a model of partial hepatic ischemia/reperfusion (I/R) injury.They are divided randomly to sham-operated control group(SH), hepatic I/R group or NAC pretreated in hepatic I/R group(I/R-NAC).The level of TNF-α in protal vein and plasma ALT were measured at 1hour and 3 hour, respectively after reperfusion.Lung tissue wet-to-dry(W/D) weight ratio compared. RESULTS: Lung tissue W/D ratio showed significant difference between two groups; The expressions of TLR2/4 mRNA in liver and lung increased obviously after hepatic I/R injury. Histological evaluation showed several changes in lung tissue in I/R group.The level of TNF-α and ALT in protal vein increased continually in I/R group at 1hour and 3 hour of reputation compared with SH group.The level of TNF-α and ALT declined significantly in the group pretreated by NAC. CONCLUSION: N-acetylcysteine can inhibit the activation of TLR2/4 and reduce TNF-α secretion resulted from I/R injury it might abate liver and lung injury following partial hepatic ischemia-reperfusion in mice.
