AIM: Hypermethylation of the promoter of the hMLH1gene, which plays an important role in mismatch repair during DNA replication, occurs in more than 30% of human gastric cancer tissues. The purpose of this study was to investigate the effects of environmental factors, genetic polymorphisms of major metabolic enzymes, and microsatellite instability on hypermethylation of the promoter of the hMLH1 gene in gastric ***: Data were obtained from a hospital-based,case-control study of gastric cancer. One hundred and ten gastric cancer patients and 220 age- and sex-matched control patients completed a structured questionnaire regarding their exposure to environmental risk *** of the hMLH1 gene promoter,polymorphisms of the GSTM1, GSTT1, CYP1A1, CYP2E1,ALDH2 and L-myc genes, microsatellite instability and mutations of p53 and Ki-ras genes were ***: Both smoking and alcohol consumption were associated with a higher risk of gastric cancer with hypermethylation of the hMLH1 gene promoter. High intake of vegetables and low intake of potato were associated with increased likelihood of gastric cancer with hypermethylation of the hMLH1 gene promoter. Genetic polymorphisms of the GSTM1, GSTT1, CYP1A1, CYP2E1,ALDH2, and L-mycgenes were not significantly associated with the risk of gastric cancer either with or without hypermethylation in the promoter of the hMLH1 *** of the hMLH1 promoter was significantly associated with microsatellite instability (MSI): 10 of the 14 (71.4%) MSI-positive tumors showed hypermethylation,whereas 28 of 94 (29.8%) the MSI-negative tumors were hypermethylated at the hMLH1 promoter *** of the hMLH1 gene promoter was significantly inversely correlated with mutation of the ***: These results suggest that cigarette smoking and alcohol consumption may influence the development of hMLH1-positive gastric cancer.

We analyzed the relationship among the tumor makers, curative resection and recurrence, ***: Among the 679 patients with gastric cancer, curative resection was 93.6%(n = 636) and noncurative resection was 6.4%(n = 43). The independent risk factors for the non-curative resection were tumor location and the positivity of preoperative serum CA 19-9 and CA 125 levels. After curative resection, the independent prognostic risk factors for recurrence in curative resection were gender, stage, and preoperative increased serum CA 125 level(HR = 2.431, P =0.020), in a multivariate analysis. CONCLUSION: Preoperative CA 125 is a useful predictive biomarker for curative resection and prognostic biomarker for recurrence in gastric cancer patients.

Bone metastasis is a rare event in patients with gastric cancer, but pathologic fracture, paralysis, pain and hematological disorders associated with the bone metastasis may influence the quality of life. We report herein the case of a 53-year-old man who presented with primary remnant gastric cancer with bone metastasis. The patient requested further investigations after detection of a metastatic lesion in the 2 nd lumbar vertebra during evaluation for back pain that had persisted for 3 mo. No other metastatic lesions were detected. He underwent total gastrectomy and palliative metastasectomy to aid in reduction of symptoms, and he received combination chemotherapy with tegafur(S-1) and cisplatin. The patient survived for about 60 mo after surgery. Currently, there is no treatment guideline for gastric cancer with bone metastasis, and we believe that gastrectomy plus metastasectomy may be an effective therapeutic option for improving qualityof life and survival in patients with resectable primary gastric cancer and bone metastasis.

Obesity is associated with a number of metabolic abnormalities such as type 2 diabetes and has become a major health problem worldwide. In the present study, we investigated the effects of Epimedium koreanum Nakai(Herba Epimedii, HE) and its main constituent icariin on the adipocyte differentiation in 3T3-L1 preadipocytes. HE extract and icariin significantly reduced lipid accumulation and suppressed the expressions of PPARγ, C/EBPα, and SREBP-1c in 3T3-L1 adipocytes. They also inhibited fatty acid synthase(FAS), acyl-Co A synthase(ACS1), and perilipin. Moreover, HE extract and icariin markedly increased the phosphorylation of AMPK. These results indicated that HE extract and icariin can inhibit the adipocyte differentiation through downregulation of the adipogenic transcription factors, suggesting that HE containing icariin may be used as a potential therapeutic agent in the treatment and prevention of obesity.
