  • Study on Gradual Oral Diethylnitrosamine Induced Cirrhotic Model in Rats under Avoirdupois Monitoring

    Objective To study the effect and feasibility of gradual oral diethylnitrosamine (DENA) induced liver cirrhotic model in rats under avoirdupois monitoring. Methods Fifty Wistar rats (6 weeks old) were divided into 3 groups: normal control group (n=10), traditional DENA induction group (receiving traditional oral DENA treatment, n=20), gradual DENA induction group (receiving gradual oral DENA treatment under avoirdupois monitoring, n=20). The weight, mortality and liver cirrhosis formation were observed. Results After 4 weeks of inducing cirrhosis, the weight of traditional DENA induction group 〔(234.9±27.1) g〕 was significantly lower than that of normal control group 〔(264.8±33.7) g, P<0.05〕. After 8 weeks of inducing cirrhosis, the weight of traditional DENA induction group 〔(251.5±34.3) g〕 was significantly lower than that of normal control group 〔(303.2±49.4) g, P<0.01〕 and gradual DENA induction group 〔(277.5±27.6) g, P<0.05〕. However, the difference between normal control group and gradual DENA induction group was not remarkable (P>0.05). The mortality in traditional DENA induction group (35%) was significantly higher than that in normal control group (0) and gradual DENA induction group (0), P<0.05. But the rate of cirrhosis formation both in traditional DENA induction group and gradual DENA induction group was 100%. Conclusion Oral DENA induced cirrhotic model in rats is a simple, reproducible and reliable technique. Gradual oral technique, in which DENA is given under avoirdupois monitoring, can improve rat’s security and reduce mortality.

  • Relationship Between The Occurrence of Colorectal Cancer and Diet Composition

    ObjectiveTo summarize the current advancement of the relationship between dietary factors and colorectal cancer in recent years, looking for more reasonable prevention measures. MethodsRelated literatures about the relationship between diet composition and the occurrence of colorectal cancer at home and abroad were collected to make a review. ResultsAmong the environmental factors, dietary factors had a close relationship with colorectal cancer, and was easy to control. Nowadays, it was believed that high animal fat, excessive alcohol consumption, consumption of fried, barbecue, and pickles may be positively associated with the occurrence of colorectal cancer. However, high fiber, high vitamin, high folic acid, the amount of minerals and trace elements in diet were negatively correlated with the occurrence of colorectal cancer. ConclusionsColorectal cancer occurs by environmental factors, genetic factors, and other factors. Diet model of people in different areas is not the same, the occurrence rate of colorectal cancer is also different, so it needs further study to explore its mechanism.

  • Disease burden and attributable risk factors of breast cancer in Chinese females from 1990 to 2019

    ObjectiveTo analyze the latest epidemiological status of breast cancer in China, trends in morbidity and mortality from 1990 to 2019, and related prognostic risk factors.MethodsData on incidence and mortality of Chinese female breast cancer, their related age-standardized rates (ASRs) from 1990 to 2019, and attributable risk factors were obtained from the Global Burden of Disease (GBD) database, and data on disability-adjusted life years (DALYs) of 34 provinces in China were obtained from literature. Joinpoint regression analysis was used to analyze the trends of ASRs. The exposure levels of each attributable risk factor and the increased cancer burden were analyzed.ResultsThe incidence of breast cancer in Chinese females increased annually, from 17.07/100 000 in 1990 to 35.61/100 000 in 2019, while the mortality rate initially increased and decreased, and then exhibited an upward trend after 2016 and there was no obvious variation from 1990 (9.16/100 000) to 2019 (9.02/100 000). Among the 34 provinces of China, Shandong Province had the most serious breast cancer burden, while Macao Special Administrative Region had the lowest. Among the seven prognostic risk factors, high body mass index (BMI) contributed the most to the breast cancer burden and the exposure risk of a diet high in red meat had shown a significant increasing trend in the past 30 years. Therefore, the disease burden caused by a high red meat diet would be increasing.ConclusionsThe incidence rate of breast cancer in Chinese females is increasing. With the development of social economy and the change of people’s dietary habits, the breast cancer burden in China trends to become heavier and heavier. Therefore, it is necessary to conduct the "three early" prevention and treatment and advocate healthy and reasonable diet and living habits to reduce the burden of breast cancer to improve prognosis and quality of life.

  • Evaluation of Dietary and Nutritional Status of Elderly Patients with Chronic Non-infectious Diseases in Community Hospitals

    ObjectiveTo evaluate the dietary and nutritional status of elderly patients with chronic non-infectious diseases in community hospitals in order to make a reasonable dietary pattern for these patients. MethodsA total of 179 elderly patients with chronic non-infectious diseases in a community hospital of Chengdu from January to September 2014 were collected, and we investigated them on their dietary status and basic personal information. The desirable dietary pattern (DDP) score was adopted to evaluate their dietary and nutritional status. ResultsDDP score of the 179 patients with chronic non-infectious diseases in the community hospital was 91.47, and the dietary quality was relatively good. While the DDP scores of animal food and edible oil exceeded the maximum allowable value, DDP scores of the staple food, fish, eggs, vegetables and fruits were lower than the expected scores. ConclusionIt is suggested that meat and other animal food intake be reduced and replaced by regular intakes of poultry, fish and shrimp, and the intake of staple food, eggs, vegetables, fruits be increased to ensure a balanced diet.

  • Analysis of Maternal and Infant Outcomes of Pregnant Women with Gestational Diabetes Mellitus

    ObjectiveTo explore the relationship between the diet during pregnancy and gestational diabetes mellitus (GDM), and analyze the effect of GDM on weight gain, outcome and complication of mother and infant. MethodsWe selected 128 GDM pregnant women and 267 non-GDM pregnant women who were investigated by semi-quantitative food frequency method during September 2009 to March 2011. Then, we collected relevant information and the data were analyzed by t-test and chi-square test. ResultsThere were statistically significant differences between the two groups in total calorie, carbohydrate, fat and protein intakes per day (P<0.05). In general, the rates of insufficient weight gain and excessive weight gain during pregnancy in the GDM group were significantly higher than the non-GDM group (P<0.05), while proper weight gain rate was significantly lower (P<0.01). The risk of hydramnion, intrahepatic cholestasis and pregnancy-induced hypertension in the GDM group was significantly higher than the non-GDM group (P<0.05), while there was no significant difference between the two groups in premature delivery, cesarean section or premature membrane ruptures (P>0.05). Apgar scores were significantly different at minute 1 and 5 between the infants in the two groups (P<0.05). The incidence of fetal death, malformation, mild neonatal asphyxia and fetal macrosomia in the GDM group was significantly higher than the non-GDM group (P<0.05). No significant differences between the two groups in low birth weight infant, cord entanglement and fetal distress were detected (P>0.05). ConclusionGDM can lead to high incidence of poor outcome and complication. It is vital to strengthen the examination and keep balanced dietary structure, in order to reduce the complication and improve the health of mother and child.
