Objective To discuss the clinical efficacy of compound gastritis mixture (CGM) in treating precancerous lesions of gastric carcinoma (PLGC).Methods Totally 85 PLGC patients were randomly divided into treatment group and control group. The treatment group took CGM and the control group took Vitacoenzyme tablets. One therapeutic course was three months, and the treatment lasted for two courses. The clinical symptoms, electronic gastroscopy presentation, and pathological tissues before and after treatment were observed, the clinical efficacy was evaluated.Results There was statistical significance in TCM syndrome between the two groups (P<0.05), and the effective rate in the treatment group was more obvious than that in the control group (P<0.01). The symptoms of the two groups were significantly improved (P<0.05,P<0.01), but the improvements of the main symptoms in the treatment group were superior to those in the control group (P<0.05,P<0.01). The total effective rate of electronic gastroscopy presentation was 80.0% (36/45) in the treatment group, which was better than that of the control group (P<0.05). Pathological curative effects of chronic atrophic gastritis, intestinal metaplasia, and dysplasia in the treatment group were also better than those in the control group (P<0.05).Conclusion CGM has definite clinical efficacy in treating PLGC.

Aim To investigate Jianpi Qinghua Chinese herbal compound( JQCC) on the expressions of the rel-evant proteins of TLR4 and its downstream MyD88-de-pendent pathways, and on the inflammatory factor TNF-α in the animal model of chronic atrophic gastritis ( CAG) in rats, so as to discuss the molecular mecha-nism of JQCC in the treatment of CAG. Methods 53 Wistar rats were randomly divided into the blank con-trol group(n=8) and the CAG model group(n=45), and the animal model of CAG in rats was replicated by the “ammonia + sodium deoxycholic acid + ethanol”method. After the successful modeling was confirmed, the rest of the 40 CAG rats in the CAG model group were divided into the model group, the vitacoenzyme-tablet group, the low dose of JQCC group, the medium dose of JQCC group, the high dose of JQCC group ( each group n =8 ) . The experimental animals of all the groups were given intragastric administration of medication continuously for 30 days. Then the patho-logical histological changes were observed by HE stai-ning. The protein expressions of TLR4, MyD88, NF-КB and COX-2 were tested by Western-blot assay. And the serum TNF-α level was measured by ELISA. Results The protein expressions of TLR4 , MyD88 , NF-КB and COX-2 and the serum TNF-α level in the rats in the model group were increased evidently ( P<0. 01). Compared with the model group, the gastric mucosa lesions were improved in the low dose of JQCC group, the medium dose of JQCC group, the high dose of JQCC group, together with significant decreases of the protein expressions of TLR4 , MyD88 , NF-κB and COX-2 and the serum TNF-α level ( P <0. 05 or P <0. 01 ) . Conclusion JQCC could effectively improve the pathological and histological changes in the gastric mucosa in CAG rats, and the therapeutic mechanism might be related to the expressions of the relevant pro-teins of TLR4-MyD88-dependent pathways and the ex-pressions of anti-inflammatory cytokines.

Objective To explore promoter methylation of HIC1 gene and the expression of HIC1/SIRT1 related to the occurrence, development, and metastasis of papillary thyroid carcinoma. Methods Using Bisulfite sequencing PCR to analyze the promoter methylation of HIC1 gene. Using quantitative real-time PCR and Western blot to analyze expression differences of HIC1 and SIRT1 genes in tissues of papillary thyroid carcinoma(40 cases) and in adjacent normal thyroid(40 cases), of which datas were analyzed by statistics. Results The degree of HIC1 gene promoter methylation was significantly higher than that in adjacent normal tissues(P<0. 01). The degree of HIC1 gene promoter methylation in papillary thyroid carcinoma was related to lymph node metastasis, age, and the tumor-node-metastasis stages(P<0. 01). Compared with the expression of HIC1 mRNA and protein in adjacent normal thyroid tissue, that in papillary thyroid carcinoma was significantly lower(P<0. 01), while the expression of SIRT1 mRNA and protein in papillary thyroid carcinoma was significantly higher(P<0. 01). The lower expression of HIC1 mRNA and protein in the tumor tissues was related to the stage of lymph node metastasis, age, and the tumor-node-metastasis stages(P<0. 05). There was a strong negative correlation between the degree of HIC1 gene promoter methylation and expression of HIC1 in papillary thyroid carcinoma(P<0. 05). The expression of HIC1 mRNA and protein between that of SIRT1 also showed a strong negative correlation(P<0. 01). Conclusion Promoter hypermethylation of HIC1 and aberrant expression of HIC1/SIRT1 in papillary thyroid carcinoma may play a significant role in the oncogenesis and progress of papillary thyroid carcinoma. HIC1 is expected to become a new marker for prevention and treatment of papillary thyroid carcinoma.
