Intervening animals by pathogen of traditional Chinese medicine (TCM) to establish animal model is the most common and easiest method to determine syndrome attribute of an animal model. However, the underlying prob-lem of this modeling method is that the concept of wind, cold and dampness in the nature are confused with the syn-drome of wind-cold-dampness summarized by abnormal appearance of clinical patients. The typical animal model establishment are through the methods of wind blowing, low temperature freezing, cold water immersion, environmen-tal humidity increasing. Modern medical modeling methods, such as chemicals, organ resections, are also used in the establishment of animal models. Then, the syndrome-attribution of modeling animal is evaluated by physicochemical indexes of modern medicine which is one of modeling methods that have been used by academia in early times. But animal model established by this method is a kind of disease model which is lack of sufficient theoretical and clini-cal evidences. Therefore, the syndrome-attribution should be reappraised among this kind of animal models.

Galectins can recognize and specifically bind to β-galactosidase,and regulate the transformation and survival of tumor cells,and promote the migration and metastasis of tumor cells,etc.Galectins correlate with tumor diagnosis,progression and prognosis.Galectias also can serve as immunoregulatory molecules to regulate the survival,activation,proliferation and differentiation of immune cells,and are components of tumor immune microenvironment.

Objective To explore the effects and mechanism of ursolic acid ( UA) on cholesterol metabolism in human hepatocellular carcinoma HepG2 and mouse hepatocyte AML-12. Methods HepG2 and AML-12 cells were treated with different concentrations of UA (0,10,20,40 μmol·L-1)for 24 h, then the mRNA and protein expression of cholesterol 7alpha-hydroxylase (CYP7A1) and intracellular cholesterol level was detected by RT-PCR、Western blotting and enzymatic method, respectively. Results Compared with 0 μmol·L-1 UA, 20 μmol·L-1 and 40 μmol·L-1 UA significantly increased the expressions of CYP7A1 mRNA and protein(P<0. 05), and decreased intracellular cholesterol level in HepG2 and AML-12 cells (P<0. 05). Conclusion A certain concentration of UA can reduce the level of cholesterol in HepG2 and AML-12 cells. CYP7A1 may be involved in the regulation process.

Recent researches of the association between helicobacter pylori (Hp) and colorectal adenocarcinoma have found that Hp infection rate is higher in the patients with colorectal cancer and other related colorectal adenoma,which suggest that Hp probably influence on local and distant intestinal mucosa epithelial cells achieve carcinogenesis by its own virulence and the role of elevated serum gastrin levels.Hp infection may be a potential risk factor of colorectal cancer.

Purpose To explore the relationship of Tei index and the concentration of plasma brain natriuretic peptide (BNP) in patients with dilated cardiomyopathy. Materials and Methods Fifty healthy individuals (control group) and fifty dilated cardiomyopathy patients (study group) were recruited in this study. BNP level was measured by enzyme-linked immunosorbent assay (ELISA). Color Doppler echocardiography were performed to measure the cardiac indices including left ventricular end-diastolic dimension (LVEDd), left ventricular end-systolic diameter (LVESd), interventricular septal thickness at diastole (IVSd), left ventricular ejection fraction (LVEF). Tei index was then calculated. The indices between the two groups were compared and correlation of Tei index and BNP with cardiac indices was analyzed. Results LVEDd, LVESd, Tei index, and BNP were significantly higher in study group than those in control group (t=14.4, 23.4, 21.9 and 22.3, P<0.01). IVSd and LVEF were significant lower in the study group (t=12.4 and 12.5, P<0.01). BNP was negatively correlated with LVEF (r= -0.266, P<0.05), and positively correlated with Tei index and LVEDd (r=0.401 and 0.326, P<0.05). Tei index was negatively correlated with LVEF and E/A (r= -0.480 and - 0.241, P<0.05), and positively correlated with LVEDd (r=0.375, P<0.05). Multiple stepwise regression analysis showed that the variates of BNP stepwise regression equation were Tei index, LVEF and LVEDd (t=5.984, -2.477 and 2.326, P<0.05); after correcting LVEF, the stepwise regression analysis showed closer relationship between Tei index and BNP (t=2.728, P<0.05). Conclusion There is correlation between Tei index and BNP. Tei index may be a good index for accurately estimating global ventricular function.

Objective:This study aimed to observe the curative effect and adverse reaction of docetaxel combined with intraperitoneal cisplatin chemotherapy and hyperthermia treatment of advanced ovarian cancer. Methods:A total of 83 patients with inoperable and recurrent advanced ovarian cancer were randomly divided into two groups:hyperthermia group and control group. The hyperthermia group consisted of 42 cases of docetaxel chemotherapy immediately treated with intraperitoneal cisplatin chemotherapy combined with abdominal local hyperthermia. The control group included 41 cases of docetaxel chemotherapy and intraperitoneal cisplatin chemotherapy treatment only. Results:The total efficiencies of the hyperthermia treatment group and the control group were 81%and 58.1%, respectively, which showed that the total efficiency significantly improved (P<0.05). The ascite control rates were 78.3%and 66.7%and CA125 decreased by 84.2%and 61.5%for the hyperthermia and control groups, respectively. The main adverse reactions were gastrointestinal reaction and bone marrow suppression. However, differences were not statistically significant. Conclusion:Docetaxel combined with cisplatin intraperitoneal perfusion hyperthermia significantly improved the curative effect on advanced ovarian cancer without increasing toxicity, which indicates that it is a treatment worth popularizing.

Objective To evaluate if expression of serum retinol-binding protein 4 (RBP4) concentrations in cholesterol gallstone disease.Methods Serum RBP4 levels of 100 cholesterol gallstone disease patients (cholesterol gallstone disease group) and 147 healthy controls (healthy control group) were measured by enzyme-linked immunosorbent assay and further correlated with clinical and biochemical characteristics,including insulin resistance and renal function.The chemical composition of gallstones was determined by postoperative pathology.Results The level of RBP4 in cholesterol gallstone disease group was significantly lower than that in healthy control group [(30.57 ± 13.64 ) mg/L vs.(41.52 ± 20.25 ) mg/L](P＜ 0.01 ).The level of RBP4 was also associated with gallstone occurrence (OR =0.93,95％ CI:0.88 -0.96,P =0.004).Serum RBP4 levels of all subjects were positively correlated with total cholesterol,triglyceride,creatinine,insulin resistance and albumin ( P ＜ 0.05 or ＜ 0.01 ),and negatively correlated with aspartate aminotransferase (P ＜0.01).In multivariate analysis,cholesterol gallstone formation was significantly associated with a lower serum RBP4 level (OR =2.97,95％ CI:1.15 -7.68,P =0.025 ).Both gallstone patients and controls were subdivided into two groups according to ceatinine:≥ 88.40 μ mol/L group and ＜ 88.40 μ mol/L group.Patients with gallstones were found to have significantly lower serum RBP4 levels than controls in both subgroups (P =0.012,0.045 ).According to GFR,both gallstone patients and controls were subdivided into ≥ 90 ml/(min· 1.73 m2) group,60 - 89 ml/(min· 1.73 m2) group and ＜60 ml/ (min· 1.73 m2) group.It showed that a lower GFR was associated with greater serum RBP4 level in healthy control group.This trend was not noted in cholesterol gallstone disease group.Conclusions Serum RBP4 decreases in cholesterol gallstone disease independent of renal function.The relationship between liver function and RBP4 level in these patients deserves further investigation.

Objective To discussed the relationship between multiple sclerosis(MS)and the genepolymorphism of HLA hoping that these results would be useful for further pathogeny studies,diagnoses,therapy and prognosis estimation of MS.Methods HLA-Ⅱ alleles in 32 patients with MS,36 nonimmunological neurological disease controls and 30 healthy controls,were identified by polymerase chain reaction-specific sequence primers(PCR-SSP)methods.Results The gene frequency of HLA-DR16 (7/32,1/36,0/30),DR11(7/32,3/36,1/30)and DQB1*0502(10/32,6/36,4/30)in patients with MS were higher than those in the 2 control groups.The gene frequency of DQB1*0601(8/32,12/36,17/30)in the patients with MS was lower than the controls.However,only the HLA-DR16 had significant difference (χ2=7.398,RR=17.94,P=0.011;χ2=5.52,RR=9.8,P=0.022).Conclusion HLA-DR16 alleles may be associated with the susceptibility to MS in Guizhou Province.
