Objective To investigate the effects of Pollen Typhae total flavone (PTF) on INS-1 pancreaticβcell damage induced by palmitic acid ( PA) . Methods INS-1 pancreatic β cells were given long-term induction with PA to establish the impaired cell model, and then were intervened with PTF. Cell viability was determined by tetrazolium salt ( XTT) colorimetry. Results PA impaired the viabilities of INS-1 pancreatic β cells in concentration- and time-dependent manner, and PTF improved the impairment of INS-1 pancreatic β cells induced by PA in concentration -dependent manner. Moreover, PTF showed better improvement on the impairment when the INS-1 pancreatic β cells were impaired more seriously by PA. Conclusion PTF has effects on ameliorating the impairment of INS-1 pancreaticβcells induced by PA for long time.

Objective To study the chemical constituents from the roots of Euphorbia sonngarica. Methods Compounds were isolated by Sephadex LH-20,MPLC,and silica gel column chromatographies. Their structures were identified by spectral methods together with physicochemical analysis.Results Eleven compounds were isolated from the roots of E.sonngarica.They were identified as cryptomeridiol (Ⅰ),betulin(Ⅱ),betulinic acid(Ⅲ),3?-hydroxy-olean-12-en-28-oic acid(Ⅳ),7-oxo-?sitosterol (Ⅴ),erythrinasinate(Ⅵ),octaeosanoie acid(Ⅶ),1-octacosene(Ⅷ),24-methene-cycloartenol(Ⅸ),eu- phol(Ⅹ),?-sitosterol(Ⅺ).Conclusion CompoundsⅠ-Ⅷare isolated from this plant for the first time.

AIM:To determine the effects of glutamine ( Gln) pretreatment on occludin protein in the rats with intestinal ischemia-reperfusion ( I/R ) injury.METHODS: Male Wistar rats ( n =30 ) were randomly divided into 3 groups (n=10):sham group, I/R group and Gln pretreatment group.The rats in Gln pretreatment group were pretreated with Gln at dose of 1 g? kg-1? d-1 by orogastric route for 7 d, and those in the other 2 groups were pretreated with the same volume of normal saline .Intestinal I/R was induced by 30-min occlusion of the superior mesenteric artery followed by 24 h of reperfusion.After the operation, the levels of IL-10, IL-2, TNF-α, SOD and MDA were measured.The occludin protein was determined by the methods of immunohistochemistry and Western blotting .RESULTS: The occludin protein level in I/R group was significantly lower than that in sham group and Gln group (P<0.05).The levels of MDA and TNF-αin I/R group were significantly higher than those in sham group and Gln group ( P<0.05 ) .The levels of SOD , IL-10 and IL-2 in I/R group were significantly lower than those in sham group and Gln group ( P<0.05 ) .CONCLUSION:Glutamine has a protective effect on occludin protein in intestinal ischemia-reperfusion injury .The mechanism may be rela-ted to oxidative stress response and inflammatory inhibition .

Termite nests is rarely seen in the clinical applications of traditional Chinese medicine, generally used for the treatment of the bone injuries and internal medical diseases. According to the recent research on termite nests, this article makes a summarize of its distribution, types, pharmacognosy characteristics, chemical composition, pharmacological effects and its application research aspects, so as to provide reference for the further development and utilization of termite nests.

Objective To discuss the expressions and clinicopathologic significances of insulin-like growth factor Ⅱ mRNA binding protein 3 (IMP3)in squamous intraepithelial lesion (SIL)and cervical squa-mous cell carcinoma (CSCC)before and after the therapy of radiation and chemotherapy.Methods The expressions of IMP3 in 80 cases of CSCC,90 cases of SIL (60 cases of HSIL,30 cases of LSIL)and 30 cases of cervicitis were detected by immunobistochemistry.The relations between IMP3 and clinicopathological cha-racteristics of CSCC were analyzed.Results The expression rates of IMP3 in CSCC,HSIL,LSIL and cervici-tis were 86.3%(69 /80),78.3%(47 /60),33.3%(10 /30)and 0(0 /30),and the difference among the four groups was statistically signicant (χ2 =87.01,P <0.01).The positive expression rate of IMP3 declined by radiation or chemotherapy (60.0% vs.85.0%,χ2 =5.79,P =0.013).The expression of IMP3 was related with lymph node metastasis (χ2 =3.97,P =0.046),differentiated degree (χ2 =5.95,P =0.018),clinical stage (χ2 =5.82,P =0.016)and invasion depth (χ2 =5.73,P =0.017).There was nothing to do with age (χ2 =0.11,P =0.745).Conclusion IMP3 expresses excessively in CSCC,and is associated with pathologi-cal grade and invasion progress.Radio-chemotherapy can reduce the expression of IMP3.

Objective To observe the effect of capsaicin on lipid deposition in liver cells and the expression of autophagy,to provide new ideas and targets for the study of fatty liver disease.Methods The model of nonalcoholic fatty liver disease (NAFLD) was established by inducing LGF cell line of liver primary cells with oleic acid (40 μg/mL).The experiment was divided into blank control group,oleic acid group,capsaicin group[oleic acid--capsaicin(100 μmol/L)].The level of intracellular lipid was detected by oil red O staining and triglyceride (TG) kit.Western bolt was used to detect the expression level of autophagy marker molecule p62 and LC3,and to calculate the ratio of LC3 Ⅱ/LC3-Ⅰ.Results After treated with 40 μg/mL oleic acid for 24 h,the oil red O staining showed that orange-red lipid droplets were found in the oleic acid group,but there was no obvious orange-red lipid droplet formation in the blank group,which suggesting that the NAFLD cell model was established successfully by using 40 μg/mL oleic acid in vitro.Oil red O staining was observed,the cells in the capsaicin group were significantly less than the oleic acid group,and the content of triglyceride in the liver cells was significantly lower than that in the oleic acid group(P＜0.05).Western bolt test results showed that capsaicin group p62 protein levels were significantly lower compared with the oleic acid group(P＜0.05),while the LC3-Ⅱ/LC3-Ⅰ ratio was higher than that of oleic acid group(P＜0.05).Conclusion NAFLD model was established by inactivating LO2 cell line with oleic acid in vitro.Capsaicin stimulated NAFLD cells,upregulated the autophagy level of NAFLD cells and reduced intracellular lipid deposition,but the specific mechanism need further study.
