Effect of Xuesaitong Soft Capsule (血塞通软胶囊) on Hemorrheology and in Auxiliarily Treating Patients with Acute Cerebral Infarction

Objective: To observe the therapeutic effect of Xuesaitong soft capsule(血塞通软胶囊, XST)and its effect on platelet counts, coagulation factor 1 (CF1) as well as hemorrheologic indexes in treating patients with acute cerebral infarction (ACI). Methods: Two hundred and four patients with ACI were assigned into two groups, the control group (n=96) and the treated group (n=108). They were all treated with conventional Western medicines, including mannitol, troxerutin, citicoline, piracetam and aspirin, while to the treated group, XST was given additionally through oral intake, twice a day, 2 capsules each time for 8 successive weeks. The clinical efficacy was evaluated according to the nerve function deficits scoring and the changes of platelet count. CF1 and hemorrheological indexes were measured before and after treatment.Results: The total effective rate was 87.0% in the treated group, and 87.5% in the control group, respectively, showing insignificant difference between them. But the markedly effective rate in the treated group ( 66.7%) was significantly higher than that in the control group (27.1%, P<0.01). The count of platelet was not changed significantly in both groups after treatment, while CF1 in them evidently lowered at the end of the 4th and 8th weeks of treatment, but showed insignificant difference between the two groups. The hematocrit, whole blood viscosity and plasma viscosity in both groups were all improved significantly after treatment, but also showed insignificant difference in comparison of the two groups. Conclusion: XST has good efficacy in auxiliary treatment of patients with ACI, though its mechanism remains to be further explored.

Effects of Hemp seed soft capsule on colonic ion transport in rats

AIM To investigate the effect of Hemp seed soft capsule(HSCC) on colonic ion transport and its related mechanisms in constipation rats.METHODS Sprague-Dawley male rats were randomly divided into three groups: normal group, constipation group and HSSC group. Rats in the constipation and HSSC groups were administrated loperamide 3 mg/kg per day orally for 12 d to induce the constipation model. Then, the HSSC group was given HSSC 0.126 g/kg per day by gavage for 7 d. The normal and constipation groups were treated with distilled water. After the treatment, the fecal wet weight and water content were measured. The basal short-circuit current(Isc) and resistance were measured by an Ussing Chamber. Besides the in vivo drug delivery experiment above, an in vitro drug application experiment was also conducted. The accumulative concentrations of HSSC(0.1 mg/m L, 0.5 mg/m L, 1.0 mg/m L, 2.5 mg/m L, 5.0 mg/m L, 10.0 mg/m L and 25.0 mg/m L) were added to the normal isolatedcolonic mucosa and the Isc was recorded. Further, after the application of either ion(Cl^-or HCO_3^-) substitution, ion channel-related inhibitor(N-phenylanthranilic acid, glybenclamide, 4,4-diisothiocyano-2,2-stilbenedisulfonic acid or bumetanide) or neural pathway inhibitor [tetrodotoxin(TTX), atropine, or hexamethonium], the Isc induced by HSSC was also measured. RESULTS In the constipation group, the fecal wet weight and the water content were decreased in comparison with the normal group(P < 0.01). After the treatment with HSSC, the fecal wet weight and the water content in the HSSC group were increased, compared with the constipation group(P < 0.01). In the constipation group, the basal Isc was decreased and resistance was increased, in comparison with the normal group(P < 0.01). After the treatment with HSSC, the basal Isc was increased(P < 0.05) and resistance was decreased(P < 0.01) in the HSSC group compared with the constipation group. In the in vitro experiment, beginning with the concentration of 1.0 mg/m L, differences in Isc were found between the experimental mucosa(with HSSC added) and control mucosa. The Isc of experimental mucosa was higher than that of control mucosa under the same concentration(1.0 mg/m L, P < 0.05; 2.5-25 mg/m L, P < 0.01). After the Cl^-or HCO_3^-removal and pretreated with different inhibitors(c AMPdependent and Ca^(2+)-dependent Cl^-channels, Na^+-K^+-2 Cl^-cotransporter(NKCC), Na^+-HCO_3^-cotransporter or Cl^-/HCO_3^-exchanger inhibitor), there were differences between experimental mucosa and control mucosa; the Isc of experimental mucosa was lower than that of control mucosa under the same concentration(P < 0.05). Meanwhile, after pretreatment with neural pathway inhibitor(TTX, atropine, or hexamethonium), there were no differences between experimental mucosa and control mucosa under the same concentration(P > 0.05).CONCLUSION HSSC ameliorates constipation by increasing colonic secretion, which is mediated via the coaction of c AMPdependent and Ca^(2+)-dependent Cl^-channels, NKCC, Na^+-HCO_3^-cotransporter or Cl^-/HCO_3^-exchanger.
