Methods： We carded out a mass screening of prostate cancer in Changchun, China, using a prostate-specific antigen assisted by Japan International Cooperation Agency. From June 1998 to December 2000, 3 940 men over 50 years old were screened. Of these, 29 men were diagnosed with prostate cancer. We selected 28 cases and matched them with controls of low prostate-specific antigen value （〈 4.1 ng/mL） by 1：10 according to age and place of employment. A case-control study of diet and prostate cancer was then carded out. Results： After adjustment for education, body mass index （BMI）, smoking, alcohol consumption, marriage and diet, intake of soybean product was discovered to be inversely related to prostate cancer. Men who consumed soybean product more than twice per week on different days had a multivariate odds ratio （OR） of 0.38 （95% confidence interval [CI], 0.13-1.12）. In addition, men who consumed soybean products more than once per day had a multivariate OR of 0.29 （95% CI, 0.11-0.79） compared with men who consumed soybean products less than once per week. The P for trend was 0.02, which showed significant difference. There was no significant difference in P trend for any dairy food. Even when we matched the cases and controls by other criteria, we found that soybean food was the only preventive factor associated with prostate cancer. Conclusion： Our study suggests that consumption of soybeans, one of the most popular foods in Asia, would decrease the risk of prostate cancer.展开更多

Many studies have examined the risk factors for NPC, yet the roles of some risk factors remain inconclusive. The purpose of this study was to examine associations between modifiable lifestyle factors and the risk of NPC in the Singaporean population.Methods: We conducted a case–control study in Singapore with 300 patients and 310 controls who were recruited between 2008 and 2012. Each control was selected and individually matched to each patient based on sex, ethnicity, and age(±5 years). A total of 290 pairs of cases and controls were matched successfully. We examined lifestyle factors such as tobacco smoking, alcohol drinking, various salted and preserved food consumption, and weaning practices.Results: After adjusting for covariates, multivariate analysis showed that those participants who were current smokers and had ever smoked tobacco had a higher risk of NPC than participants who had never smoked, with odds ratios(ORs) of 4.50(95% confidence interval [CI] 2.58–7.86; P < 0.001) and 2.52(95% CI 1.54–4.12; P < 0.001), respectively. Those who consumed salted vegetables at least once a week also showed a significantly increased risk of NPC than those who never or rarely consumed salted vegetables, with an OR of 4.18(95% CI 1.69–10.38; P = 0.002).Conclusion: Smoking(currently and ever-smoked) and consuming salted vegetables once a week or more were lifestyle risk factors for NPC, and changes of these factors for the better may reduce the risk of NPC.展开更多

Anti-obesity interventions are therefore urgently needed. An earlier study has demonstrated that treatment with an herbal formula MCC, which comprises the fruit of Momordica charantia (MC), the pericarpium of Citri reticulate (CR) and L-carnitine (CA), reduced the weight gain in high fat diet (HFD)-fed mice. In the present study, we investigated the effect of long-term treatment with MCC (6 g/kg/day × 40 doses) and various combinations of its constituents in HFD-fed female ICR mice. Body weight change was monitored during the course of the experiment. Total and differential adiposity, plasma lipid contents, metabolic enzyme activities and mitochondrial coupling efficiency in skeletal muscle were measured. Glucose homeostasis was also assessed. Results showed that HFD increased the body weight, total and differential adiposity, and plasma lipid contents as well as impaired metabolic status in skeletal muscle and glucose homeostasis. MCC and all combinations of its constituents reduced the weight gain in HFD-fed mice, which was accompanied with an improvement on glucose homeostasis. While MC, CA and CR independently suppressed the HFD-induced weight gain in mice, MC seems to be the most effective in weight reduction, all of which correlated with the induction of mitochondrial uncoupling in skeletal muscle. Only CA and CR, but not MC, significantly reduced the total adiposity and visceral adiposity as well as plasma cholesterol level. However, the two component combinations, MC + CR and MC + CA, decreased the degree of visceral adiposity and plasma cholesterol level, respectively. MCC treatment at 1.5 g/kg (but not a higher dose of 6 g/kg) suppressed visceral adiposity and induced mitochondrial uncoupling in skeletal muscle in HFD-fed mice. The finding suggests that MCC may offer a promising prospect for ameliorating the diet-induced obesity and metabolic disorders in humans.展开更多
