Objective To explore the correlation between serum adipokines and cytokines levels in obese patients with colon cancer.Methods 53 patients with obese colon cancer treated in our hospital from January 2011 to June 2013 were selected as the observation group and at the same time 51 cases of non-obese colon cancer were selected as the control group.TNF-α,IGF-1,VEGF and adipokines levels were measured in the two groups.Results The IGF-1 level in the stage A-B and the stage C-D of the ob-servation group was significantly increased compared with the same stages of the control group (P <0.05).The TNF-α,IGF-1 and VEGF levels in the stage C-D of the observation group were significantly higher than those in the stage A-B (P <0.05 ),the TNF-αand VEGF levels in the stage C-D of the control group were significantly increased compared with the stage A-B (P <0.05).The visfatin and leptin levels in the stage A-B of the observation group were significantly increased compared with the same stages of the control group (P <0.05),the visfatin,resistin and leptin levels in the stage stage C-D of the observation group were significantly increased compared with the same stages of the control group (P <0.05).Visfatin was positively correlated with IGF-1 and VEGF (P <0.05),resistin was positively correlated with IGF-1 (P <0.05 ),leptin was positively correlated with TNF-α, IGF-1 and VEGF (P <0.05).Conclusion Obvious lipid metabolism and cellular cytokines disorders exist in obese colon cancer, their disorder level could promote the progression of colon cancer.

Objective: To establish p53 trancated muteins group and analyse their expression and effects on p53 related downstream genes in HeLa cells. Methods: Using PCR-based site-directed mutagenesis technique, a group of P53 muteins with the N- and/or C-terminals differently trancated were set up. The plasmids with p53 mutein genes were used to transfect HeLa cells, the p53 muteins and some p53 related downstream genes' expression were analyzed by RT-PCR. Results: The p53 muteins were expressed in HeLa cells and they had effects on some of p53 related downstream genes. Conclusion: The P53 muteins may be a good tool to analyze P53 function and has effects on p53 related downstream genes' expression model.

Objective: To prepare highly purified THANK protein. Methods: THANK was efficiently expressed in E.coli as inclusion bodies. After bacteria were lysed under ultrasonication, TE buffer,1% TritonX and 2 mol /L urea was used to efficiently extract inclusion bodies. After denaturation with 8 mol/L urea,THANK was partially purified by Sephacryl S-200 chromatography, and then subsequent refolding step was optimized for a maximal recovery of biological active protein. The renatured THANK was purified to homogeneity with Q Sephadex Fast Flow gel filtration and then desalted by Sephadex G-25 chromatography. Results: The purity of biologically active THANK was above 97% in SDS-PAGE densitometric studies. Conclusion: An effective method of denaturation, renaturation and purification of recombinant THANK is established.

OBJECTIVETo assess the atherogenicity of lipoprotein(a), the effect of the heterogeneity of lysine binding of apolipoprotein(a) [apo(a)], a plasminogen-like glycoprotein component on the proliferation of human arterial smooth muscle cells (SMCs).

METHODSBoth wild type (wt) Trp72 and mutant (mut) Trp72-->Arg forms of apo(a) kringle IV-10 were expressed by employing a GST-gene fusion system into E. coli. The proliferation of SMCs was determined by flow cytometry and MTT colorimetry. Enzyme-linked immunosorbent assay (ELISA) assay was used to detect the active form of transforming growth factor beta(1) (TGF-beta(1)).

RESULTSApo(a) wt-kringle IV-10 that has lysine binding properties possessed a growth-stimulating activity to SMCs on a dose-dependence manner by stimulating cells in the G(1)/G(0) phase of cell cycle to S and G(2)/M phase, and reduced significantly the amounts of endogenous active TGF-beta(1) in culture when compared with the control medium and the GST group (2.4 +/- 0.5 vs 8.6 +/- 1.6 and 9.1 +/- 1.7 ng/ml, P < 0.01). The growth-stimulating effect of apo(a) mut-kringle IV-10 deficient in lysine binding was negligible.

CONCLUSIONSApo(a) induces SMCs growth by inhibiting the activation of latent TGF-beta(1), an activity that may involve the ability of apo(a) kringle IV-10 to bind lysine. The mitogenic effect of apo(a) wt-kringle IV-10 on SMCs might play an active role in the atherogenic function of lipoprotein(a).

Objective:To investigate the dose-effect relationship of Xianfu ointment and its decomposed recipes the 1-chloro-2,4-dini-trochlorobenzene(DNCB) induced chronic eczema in mice, and confirm the median effective dose (ED50) of each formula and the synergetic effect by compatibility. Methods:DNCB was used to induce chronic eczema in C57 mice. The mice were treated with gradient dosages of the Xianfu ointment (11.71-11 662.50 mg?kg-1?d-1,k = 0.316), Anemone flaccid (0.53-530.12 mg?kg-1?d-1,k = 0.316), Xianfu ointment without Anemone flaccid (11.18-11 132.40 mg?kg-1?d-1,k =0.316),respectively. The pathological features were observed after hematoxylin-eosin staining. The volume ratio of epidermides and the number of lymphocyte infiltrated in dermis were analyzed with morphometry. The serum levels of IL-2,IFN-γ,IL-4,and IL-13 were detected by ELISA assay. The ED50was calculated by non-linear regression with various slope using Prism-5.0 software.Results:The effects of Xianfu ointment and its decomposed recipes on chronic eczema showed a dose-dependent tendency. The dose-response curves showed"S"shape. The efficacy of Xianfu ointment on chronic eczema was the most significant among the three formulas, which was demonstrated by decreased epidemical thicknes (ED50= 377.90 mg?kg-1?d-1), reduced infiltrated lymphocyte number(ED50= 153.20 mg?kg-1?d-1), increased serum IL-2(ED50=608.90 mg?kg-1?d-1) and IFN-γ (ED50= 205.50 mg?kg-1?d-1) levels, and decreased serum IL-4(ED50= 198.70 mg?kg-1?d-1) and IL-13 levels (ED50= 117.60 mg?kg-1?d-1). And the dose-effect curves of Anemone flaccid and Xianfu ointment without Anemone flaccid groups were both right shift when compared with that of Xianfu ointment. Conclusion:Xianfu ointment and its decomposed recipes can effectively treat chronic eczema. Anemone flaccid has obvious compatibility synergy in the whole formula. The effects of Xianfu ointment is most significant.

Objective: To study the dose-effect relationship of Yuning ointment and its decomposed recipes in the treatment of oleic acid induced acne in mice. Methods: Oleic acid was administrated to the back (2 cm ×2 cm) of the mice (once a day) for 21 days to induce acne. At d22, the gradient dosage of Anemone flaccida crude drug (1. 06-1 060. 23 mg?kg-1?d-1,k=3. 16), Yuning oint-ment without Anemone flaccida crude drug (4. 73-1 767. 75 mg?kg-1?d-1, k=3. 16) and Yuning ointment (2. 84-2 827. 28 mg?kg-1?d-1, k=3. 16) was respectively administrated to the back of mice for 14 days. The pathological changes of skin were observed by hematoxylin-eosin (HE) staining. The diameter of sebaceous glands and the ratio of follicular keratinization area were morphomet-rically analyzed. The serum levels of IL-1, IL-6 and TNF-α were detected by ELISA assay. The median effective dosages (ED50) of A-nemone flaccida in the three prescriptions were regressed by Prism 5. 01 software to determine the prescription dose-effect. Results: All the therapy groups were with significantly relieved pathological changes of sebaceous glands hypertrophy and follicular keratinization, and decreased serum levels of IL-1, IL-6 and TNF-α in a dose-dependent manner. The dose-response curves showed an "S" shape. A-mong the three therapy groups, the effect of Yuning ointment was the best. The ED50of Yuning ointment regressed by Anemone flaccida dose was 0. 28-fold for improving sebaceous glands hypertrophy, 0. 14-fold for inhibiting follicular keratinization, and 0. 15-, 0. 49-and 0. 24-fold for decreasing serum levels of IL-1, IL-6 and TNF-α. . Regressed by Yuning ointment without Anemone flaccida, the ED50of Yuning ointment was lower than Yuning ointment without Anemone flaccid in terms of improving pathological changes and inhibiting the secretion of cytokines. Conclusion: Yuning ointment can prevent and treat acne through regulating immune function. And the prescrip-tion compatibility can enhance the effects of Anemone flaccida.
