ABSTRACT
Objective A variety of secondary metabolites can be obtained after the fermentation of medicinal fungi.The con-tent of these metabolites is much higher than that of cultivated medicinal fungi. We aimed to preliminarily study on the apoptosis of fer-mented Inonotus obliquus(FIO) on hepatocellular carcinoma HepG-2 cells. Methods The experiment was divided into 3 groups:the control group(The same volume of drug-free medium),the UIO group(200 mg/L) and the FIO group(200 mg/L). The contents of polysaccharides,terpenoids and polyphenols in unfermented Inonotus Obliquus (UIO) and FIO were determined by sulfuric acid phenol method,Folin-Ciocalteu method and colorimetric method. Effects of Fermented Inonotus obliquus on apoptosis of HepG-2 Cells were measured by MTT Method and Flow Cytometry. Results The contents of polysaccharides,terpenoids and polyphenols were sig-nificantly increased in FIO group [(10.140±0.849)mg/mL,(1.774±0.001)mg/mL, (9.979±0.022)mg/mL] compared with thatin UIO group [(7.161±0.305)mg/mL,(1.358±0.004)mg/mL,(6.314±0.237)mg/mL](P<0.01). Both UIO and FIO group induced apoptosis of HepG-2 cells according to Annexin V/PI double staining. Compared with the control group(4.3%),the apoptosis rate in-creased in UIO and FIO group (23.14%,27.37%) (P<0.05). In addition, the apoptosis rate was higher in FIO group than that in UIO group (P<0.05). Compared with the control group, the ratio of G0/G1phase cells was significantly increased and the ratio of S phase and G2/M phase was significantly decreased in UIO and FIO group (P<0.01). G0/G1phase cell ratio differences were statistically signif-icant compared with the UIO group (P<0.05) Conclusion FIO can better induce the apoptosis of HepG-2 cells than UIO.
ABSTRACT
<p><b>OBJECTIVE</b>To explore effect of acupuncture at Zusanli (ST 36) and Xuanzhong (GB 39) on cerebrovascular function in the patient of ischemic stroke.</p><p><b>METHODS</b>Three central, single blind, randomized controlled trial method was adopted, and 160 cases were randomly divided into an acupuncture group and a control group, 80 cases in each group. The two groups were treated by routine treatment for ischemic stroke with acupuncture at Zusanli (ST 36) and Xuanzhong (GB 39) added in the acupuncture group. Changes of TCD cerebrovascular blood flow indexes before and after treatment were evaluated.</p><p><b>RESULTS</b>After treatment, TCD indexes significantly improved in the acupuncture group (P < 0.05, P < 0.01) with a significant difference as compared with that in the control group (P < 0.05).</p><p><b>CONCLUSION</b>Acupuncture at Zusanli (ST 36) and Xuanzhong (GB 39) can significantly improve cerebral vasomotoricity, cerebral blood flow auto-regulative function, cerebral hemisphere collateral circulation comprehental function in the patient of ischemic stroke.</p>
