To study the chemical constituents from Zanthoxylum simulans and their anti-inflammatory activity. The constituents of Z. simulans were isolated and purified using various column chromatographies. Their chemical structures were elucidated using extensive spectroscopic methods. The compounds were assayed inhibitory activity against NO production in LPS stimulated RAW 264.7 cells. Four compounds were obtained from the ethanol extract of Z. simulans and determined to be isozanthpodocarpin B(1), kobusin (2), (+)-fargesin (3), and epieudesmin (4). Compound 1 exhibited NO production inhibitory effect with IC50 value of 14.49 µmol · L(-1). Compound 1 is a new dimeric lignan and may be serve as potential anti-inflammatory agent in the future.

OBJECTIVETo compare the difference of Euphorbia Pekinensis Radix before and after being processed with vinegar in the toxicity on rat small intestinal crypt epithelial cells IEC-6, and make a preliminary study on the mechanism of detoxication of Euphorbia Pekinensis Radix processed with vinegar.

METHODWith rat small intestinal crypt epithelial cells IEC-6 as the study object, the MTT method was adopted to detect the effect of Euphorbia Pekinensis Radix before and after being processed with vinegar on IEC-6 cell activity. The morphology of cells were observed by the inverted microscope. The down-regulated mitochondrial apoptosis pathway of enterocytes caused by the vinegar processing was analyzed by using the high content screening.

RESULTCompared with the negative control group, the proliferation inhibition experiment showed that Euphorbia Pekinensis Radix showed a relatively high intestinal cell toxicity (P < 0.01). The results of HCS analysis showed that Euphorbia Pekinensis Radix could significantly reduce the cell nucleus Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.01), and increase Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.01). After being processed with vinegar, compared with Euphorbia Pekinensis Radix groups with different doses, Euphorbia Pekinensis Radix processed with vinegar could significantly decrease the cell proliferation inhibition effect on enterocytes, increase the cell nuclear Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.05), and decrease Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.05), and showed a certain dose-effect relationship.

CONCLUSIONThe vinegar processing can further reduce the toxicity of Euphorbia Pekinensis Radix on enterocytes. Its possible mechanism can decrease the effect of Euphorbia Pekinensis Radix on the permeability of IEC-6 cell membrane, so as to provide a basis for further explanation of the detoxication mechanism of Euphorbia Pekinensis Radix processed with vinegar.

Objective To detect the expression of Id1 and HBx in HBV-related hepatocellular carcinoma (HCC) tissue samples and analyzed the correlation between Id1 expression levels and clinicopathological features of patients.Methods Tumor tissue samples obtained from a total of 113 HCC patients.The expression of Id1 proteins of these samples were detected by immunohistochemical (IHC) staining and evaluated by two independent pathologists.The corrections between the clinical pathological parameters and the IHC scores for Id1and the prognostic significance were statistical analyzed by SPSS 19.0 software.Results Ninty-six of 113 patients is HBV-related HCC.Over-expression of Id1 were found positively correlated with the HBsAg ＞ 200 s/n,histological grade,portal vein invasion.Patients with Id1 overexpression had both shorter disease-free and overall survival times.Conclusions High expression of Id1 was correlated with serum HBsAg,histological grade,portal vein invasion and poor clinical outcomes in HBV-related HCC.

Objective To observe and compare the efficacy and safety between propofol-fentanyl and propo- fol-ketamine for anesthesia of artificial abortion.Methods 450 ASA physical statusⅠandⅡpatients scheduled for elective artificial abortion were randomized into three groups:P group were given intravenous normal saline 2ml be- fore propofol(n=150) ;PF group were given intravenous fentanyl 1?g/kg then propofol(n=150);PK group were given intravenous ketamine 0.4mg/kg then propofol(n=150).Total dose of propofol,extinction time of lash reflex, heart rate(HR),mean arterial pressure(MAP),pulse oxygen saturation(SpO_2),time to open the eye when called, time of full recovery(answering correctly and walking unaided),discomfort,awareness during operation,self-feeling were recorded.Analysis of date was with SPSS 12.0.P＜0.05 was considered significant.Results No episodes of nausea,vomiting,cardio-cerebral syndrome or awareness were noted in all patients;Total dose of propofol,and extinc- tion time of lash reflex in P group were significantly more than those in PK or PF group(P＜0.05),but there was no difference between PK and PF group;MAP,minimum HR and SpO_2 during operation were obviously lower than preoperation or postoperation in those in P or PF group,minimum HR and SpO_2 during operation in P group were significantly lower than in PF or PK group;Minimum HR and SpO_2 during operation in PK group were lower than preoperation,but its decrease extent was less than that in P or PF group(P＜0.05);Time to eye opening in PF or PK group was significantly less than that in P group(P＜0.05);Time to full recovery were not different in three groups;Incidence of pain on injection in PF group(10%)or PK group(8%)was obviously lower than P group (80%);Incidence of coughing and moving during operation in PF group(8%)or PK group(6%)was obviously less than P group(30%);No difference were noted with respect to degree of comfort,time of full recovery,bleeding vol- ume during operation,time to operation.Conclusion Painless artificial abortion can be preformed effectively and safely with propofol-fentanyl or propofol-ketamine,propofol-ketamine especially fits for painless artificial abortion compared with propofol-fantanyl.

Objective To observe the effects of low frequency electrostimulation(LFES)on sleep disorder of patients after acute cerebral infarction(ACI)as evaluated by using polysomnography,and on the recovery of neurological deficits. Methods Seventy cases of acute cerebral infarction were randomly divided into two groups,a treatment group and a control group.Both groups were treated with routine drugs, and the treatment group was also treated with LFES in addition.The changes of neurological deficits(ND) scores and such parameters of polysomnography as sleep latency(SL),total sleep time (TST),sleep efficiency(SE%),sleep maintenance(SMT),rapid eye movement sleep(REM),REM latency(RL),REM time(RT),REM activity(RA),REM density(RD).stage 1 sleep(S1),stage 2 sleep(S2)and deep sleep (S3+4) were observed.Results It was shown that,after treatment,both groups got significant improvement in terms of the ND scores and all the polysomnography parameters except RA,S1 and S2,(P<0.01),and the treatment group improved to a significantly greater extend when compared with the control group (P<0.01).Conclusion It is concluded that LFES could promote recovery of neural function and sleep disorder of ACI patients.
