Objective To study the mechanism of killing and apoptosis-inducing effects of Capparis spinosa alkaloid (CSA) on human hepatocarcinoma cell line HepG2. Methods The killing effect of CSA on human hepatocarcinoma cell line HepG2 was studied by MTT method. Morphological observation of HepG2 cells was carried out by fluorescence microscope. Results The CSA had obvious cytotoxicity on the HepG2 in a dose-dependent manner and its IC50 value was 142.82 ?g/mL. The HepG2 cells showed the characteristic morphologic changes of apoptosis by the function of CSA and the apoptosis percentage is higher than that of the natural one. The progress of cells cycle from S phase to G2 phase had been blocked by CSA. The intracellular Ca2+ level had been increased by the function of CSA, which was positively related with drug concentration. Conclusion CSA has obviously killing and apoptosis-inducing effects on human hepatocarcinoma cell line HepG2 and calcium overload might also be invovled in these events.

China Journal of Chinese Materia Medica 2010;35(10):1335-1338
OBJECTIVETo learn the effects of coptis in treating neonatal jaundice and to find the index that guides the clinical administration of the medicine.
METHODClinical data of 412 cases of neonatal jaundice were studied retrospectively, and univariate and multivariate analysis were made to the factors affecting the incidence according to the Cox model which led to the establishment of the predictive equation. According to the regression coefficients, the relative risk, wald value, the coptis effects were evaluated on the incidence of neonatal jaundice.
RESULTSingle-factor Cox model analysis shows that there are five main factors affecting the incidence of neonatal jaundice, Multivariate Cox model analysis indicates that the five main factors are also independent factors that affect the incidence, the roles of which, ranking from minor to major are, in turn, age, applied coptis, ethnic, G6PD deficiency and cesarean section. Among them, the regression coefficient is -0.259, relative risk 0.772, wald value 6.832. It sugguests that coptis may reduce the incidence of neonatal jaundice, and that it is a protective factor. The prediction equation, by regression coefficients, which has been used to establish the incidence of neonatal jaundice, is as following: h(t, x) = h0 (t) exp (- 0.022 x2 - 0.494x3 + 0.344x8 + 0.226x9 - 0.259x10).
CONCLUSIONCoptis is one of the important factors that affect the occurrence of neonatal jaundice, and it has a protective effect in preventing neonatal jaundice from occurrence.

OBJECTIVETo observe the effect of Huogu II formula compatible with different channel ushering drugs on the homing of bone marrow stem cells of osteonecrosis of the femoral head (ONFH) induced by liquid nitrogen freezing in rabbits and discuss the mechanism for preventing and treating ONFH.
METHODThe ONFH model was established by liquid nitrogen freezing of 84 rabbits. They were randomly assigned to the model group and the Huogu II formula group and groups of Huogu II formula combining with Achyranthis Bidentatae Radix, Asari Radix et Rhizoma, Angelicae Pubescentis Radix, Platycodonis Radix. The remaining 14 rabbits were sham-operated. During the course of ONFH modeling, all of the rabbits were subcutaneously injected with recombinant human granulocyte colony-stimulating factor (rhG-CSF)(30 microg x kg(-1) x d(-1), for consecutively 7 days). Meanwhile, normal saline and decoction of the formulae were orally administrated respectively. WBC was counted in peripheral blood before and after the injection of rhG-CSF. HE stainings at the 2nd and the 4th weeks after the modeling were adopted to observe histopathological changes, vascular morphology was observed by ink perfusion, BrdU and SDF-1 were determined by immunohistochemical assay in femoral heads of the left hind leg.
RESULTCompared with the sham-operated group, the Huogu II formula group showed decrease in the ratio of empty lacuna and increase in vessel area, number of BrdU positive cells and SDF-1 level. In comparison with the model group, the Achyranthis Bidentatae Radix group displayed decreasing empty lacuna ratio and increasing vessel area at the 4th week and increasing SDF-1 at the 2nd week; the Platycodonis Radix group revealed a notably increasing empty lacuna ratio and a sharp decrease in the number of BrdU positive cells at 4th week; Asari Radix et Rhizoma and Angelicae Dubescentis Radix groups showed no remarkable change.
CONCLUSIONHuogu II formula can promote the directional homing of bone marrow stem cell to the necrosis area. Channel ushering drug achyranthes can further boost above effects of Huogu II formula.

PartⅡ The well-growth BV2 microglia were divided into 2 groups ( n=30 each) using a random number table method: LPS+ LXA4 group (group LL2) and LPS+ LXA4+ SIRT1 inhibitor EX527 group (group LLE). Cells in group C were commonly cultured without any treatment. In LXA4 group and LPS group, LXA4 (final concentration 100 nmol/L) and LPS (final concentration 100 ng/ml) were added respectively, and then the cells were incubated for 24 h. In LL1 group and LL2 group, LXA4 (final concentration 100 nmol/L) was added at 1 h before treatment with LPS, and the other treatments were similar to those previously described in LPS group. EX527 (final concentration of 5 μmol/L) was added at 30 min before treatment with LXA4, and the other treatments were similar to those previously described in LL2 group.The expression of inducible nitricoxide synthase (iNOS), CD32, arginine synthase 1 (Arg-1), CD206, interleuckin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α) and IL-10 mRNA was detected by real-time polymerase chain reaction. The concentrations of IL-1β, IL-6, TNF-α and IL-10 in the supernatant were measured using enzyme-linked immunosorbent assay. The content of ROS was detected by DCFH-DA. The activity of SOD was measured by WST-8 assay. The expression of NADPH oxidase 2 (NOX2), superoxide dismutase 1 (SOD1), heme oxygenase-1 (HO-1), SIRT1 and acetylated NF-κB p65 was detected by Western blot. Results:Compared with group C, the expression of iNOS, CD32, IL-1β, IL-6 and TNF-α mRNA was significantly up-regulated, the concentrations of IL-1β, IL-6 and TNF-α in the supernatant were increased ( P<0.05), no significant change was found in the expression of Arg-1, CD206 and IL-10 mRNA and IL-10 concentrations in the supernatant, the expression of NOX2 and HO-1 was up-regulated, SOD1 expression was down-regulated, the activity of SOD was decreased, the content of ROS was increased, the expression of SIRT1 was down-regulated, and the expression of acetylated NF-κB p65 was up-regulated in group LPS ( P<0.05). Compared with group LPS, the expression of iNOS, CD32, IL-1β, IL-6 and TNF-α mRNA was significantly down-regulated, the expression of Arg-1, CD206 and IL-10 mRNA was up-regulated, concentrations of IL-1β, IL-6 and TNF-α in the supernatant were decreased, the concentration of IL-10 was increased, the expression of NOX2 was down-regulated, the expression of HO-1 and SOD1 was up-regulated, the activity of SOD was increased, the content of ROS was decreased, the expression of SIRT1 was up-regulated, and the expression of acetylated NF-κB p65 was down-regulated in group LL1 ( P<0.05). Compared with group LL2, the concentrations of IL-1β, IL-6 and TNF-α in the supernatant were significantly increased, the activity of SOD was decreased, the content of ROS was increased ( P<0.05), and no significant change was found in the IL-10 concentration in the supernatant in group LLE ( P>0.05). Conclusions:LXA 4 can inhibit LPS-induced polarization of microglia to M1 phenotype, and the mechanism may be related to enhancement of SIRT1 activity and inhibition of NF-κB transcriptional activity.
