Objective To study the effects of irradiation and W11-a12,a kind of repair-promoting drug,on anion-selective channel in membranes of mouse peritoneal macrophage. Methods The activity of anion-selective channel was recorded from cell-attached patches with patch clamp techniques. Results The effects of irradiation on anion-selective channel in membranes of peritoneal macrophage included:①decreasing the mean number of activated channels by the presence of zymosan; ②prolonging the mean time from stimulus to the opening of channels; ③depressing the opening of channels by decreasing open-state probability,shortening open-time and prolonging close-time. The effects of irradiation could partly be depressed by W11-a12. Conclusion Irradiation will depress the anion-selective channel of peritoneal macrophage, which may be an important way to depress the function of macrophage.

In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

Objective To analyze the electrocardiography(ECG)data of pressure overload-induced cardiac hy pertrophy rats.Methods Pressure overload cardiac hypertrophy was induced by abdominal aorta constriction. Echocardiogram and heart weight measurement demonstrated the occurrence of cardiac hypertrophy.Standardized ECG parameters of limb and chest were measured and statistically analyzed.Results Two weeks after hypertrophy models were established,echocardiogram showed greater LVPWTd,IVSTd,LVDd.ECG showed that left axis deviation and higher R waves in V_A,V_B,V_C(P

To control the quality of Maca, the quality standard was established in this study. According to the methods recorded in the Appendix of Chinese Pharmacopoeia (2010 Edition), the water, extract, total ash, acid insoluble substance, and heavy metals inspections in Lepidium meyenii were carried out. N-benzyl-9Z, 12Z-octadecadienamide in L. meyenii was identified by TLC, and it was determined by HPLC. The results showed that the N-benzyl-9Z, 12Z-octadecadienamide identification of TLC was a strong mark and specificity. In content determination experiment, the linearity of N-benzyl-9Z, 12Z-octadecadienamide was in the range of 0.01-2 microg (r = 0.9998), and the average recovery (n=9) was 99.27% (RSD 2.0%). The methods were simple, accurate, with good reproducibility. It is suitable for quality control L. meyenii.

BACKGROUND:Previous studies concerning neuromechanism of acupuncture for regulating gastric function mainly focused on peripheral nerve, involving in central nervous system. In particular, there are few studies addressing higher central nervous system.
OBJECTIVE:To explore the effects of acupuncture at Neiguan (PC6) and Zusanli (ST36) on gastric-related neurons in the hypothalamic paraventricular nucleus.
METHODS:Using microelectrode extracellular recording technique, gastric related neurons in the paraventricular nucleus were found in gastric distension rats. Stimulation was conducted for 30 seconds by hand acupuncture at Neiguan and Zusanli. The effects of acupuncture on gastric-related neurons in the paraventricular nucleus were observed.
RESULTS AND CONCLUSION:The discharge of 109 neurons in the hypothalamic paraventricular nucleus of 60 rats was recorded. A total of 56 gastric-related neurons of the 109 neurons were observed. The number of neurons response to acupunctures at Zusanli, Neiguan, Pishu (BL20) and Weishu (BL21) were respectively 44, 47, 29, and 33, with the reaction proportion of 78.57%, 83.47%, 51.79%and 58.93%. Results suggested that there exist gastric distension stimulation and acupuncture stimulations from neurons soma to visceral reaction in the hypothalamic paraventricular nucleus, which simultaneously participates in the regulation of acupuncture on the gastric function.
