OBJECTIVE: High-fat diet is one of the main risk factors that disrupt the balance of gut microbiota, which eventually will induce colorectal cancer (CRC). Evodiamine (EVO) is a wildly used multifunctional traditional Chinese medicine extract. In this study, we investigated the role of gut microbiota in high-fat diet-propelled CRC and the potential of EVO for CRC chemoprevention. METHODS: Gut microbiota, serum d-lactic acid and endotoxin from 38 patients with colon cancer and 18 healthy subjects were detected by quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA). In addition, body mass index, phospho-signal transducer and activator of transcription 3 (p-STAT3) expression in cancer tissues and paracancerous tissues were detected by immunohistochemistry. A mouse intestinal inflammatory tumor model was established by azomethane/sodium dextran sulfate, followed by treatment with EVO and 5-aminosalicylic acid (ASA). Gut microbiota and inflammatory factors were detected by quantitative polymerase chain reaction, while serum d-lactic acid and endotoxin were detected by ELISA. Furthermore, cell proliferation, cell apoptosis, and interleukin (IL)-6/STAT3/P65 pathway were evaluated by 5-ethynyl-2'-deoxyuridine, terminal-deoxynucleotidyl transferase-mediated nick-end labeling, and Western blot assays. RESULTS: In patients with colon cancer, the numbers of Enterococcus faecalis and Escherichia coli were increased, while those of Bifidobacterium, Campylobacter and Lactobacillus were decreased. Serum endotoxin and d-lactic acid levels and p-STAT3 levels were significantly increased. In the mouse model, both EVO and ASA inhibited tumor formation, decreased the proliferation of tumor cells, and induced apoptosis of tumor cells. Compared with the control group, the numbers of E. faecalis and E. coli were decreased, while Bifidobacterium, Campylobacter and Lactobacillus numbers were increased. In the EVO group, serum endotoxin and d-lactic acid levels and inflammatory factors were significantly decreased. Further, the IL6/STAT3/P65 signaling pathway was inhibited in the EVO group. CONCLUSION EVO may inhibit the occurrence of colon cancer by regulating gut microbiota and inhibiting intestinal inflammation. The potential mechanism involves inhibition of the IL6/STAT3/P65 signaling pathway, revealing its potential therapeutic significance in clinical applications.

Objective: To determine the prevalence and determinants of folic acid (FA) supplementation in Chinese couples planning for pregnancy and in women during early pregnancy. Methods: This was a cross-sectional study based on the Shanghai PreConception Cohort (SPCC) study. Data on FA supplementation and socio-demographic features were collected using questionnaires. Couples visiting clinics for pre-pregnancy examination and pregnant women at < 14 gestational weeks were recruited in Shanghai, China, between March 2016 and September 2018. Results: Among the pregnancy planners, 42.4% (4,710/11,099) women and 17.1% (1,377/8,045) men used FA supplements, while 93.4% (14,585/15,615) of the pregnant women used FA supplements. FA supplement use was higher in female pregnancy planners who were older ( : 1.13, 95% : 1.08-1.18), had higher education ( : 1.71, 95% : 1.53-1.92), and were residing in urban districts ( : 1.06, 95% : 1.01-1.11) of FA supplementation; female pregnancy planners with alcohol consumption ( : 0.95, 95% : 0.90-0.99) had lower odds of FA supplementation. In early pregnancy, women with higher educational level ( : 1.04, 95% : 1.03-1.06), who underwent pre-pregnancy examination ( : 1.02, 95% : 1.01-1.03) had higher odds of using an FA supplement; older aged ( : 0.99, 95% : 0.98-0.99), and multigravida ( : 0.97, 95% : 0.96-0.98) had lower odds of FA supplementation. Conclusion Although the majority of pregnant women took FA supplements, more than half of the women planning for pregnancy did not. Urgent strategies are needed to improve pre-conception FA supplementation.

Objective: This study aimed to assess the association of waist circumference (WC) with all-cause mortality among Chinese adults. Methods: The baseline data were from Shanxi Province of 2002 China Nutrition and Health Survey. The death investigation and follow-up visit were conducted from December 2015 to March 2016. The visits covered up to 5,360 of 7,007 participants, representing a response rate of 76.5%. The Cox regression model and floating absolute risk were used to estimate hazard ratio and 95% floating of death by gender and age groups (≥ 60 and < 60 years old). Sensitivity analysis was performed by excluding current smokers; participants with stroke, hypertension, and diabetes; participants who accidentally died; and participants who died during the first 2 years of follow-up. Results: This study followed 67,129 person-years for 12.5 years on average, including 615 deaths. The mortality density was 916 per 100,000 person-years. Low WC was associated with all-cause mortality among men. Multifactor-adjusted hazard ratios ( ) were 1.60 (1.35-1.90) for WC < 75.0 cm and 1.40 (1.11-1.76) for WC ranging from 75.0 cm to 79.9 cm. Low WC (< 70.0 cm and 70.0-74.9 cm) and high WC (≥ 95.0 cm) groups had a high risk of mortality among women. The adjusted s of death were 1.43 (1.11-1.83), 1.39 (1.05-1.84), and 1.91 (1.13-3.22). Conclusion WC was an important predictor of death independent of body mass index (BMI). WC should be used as a simple rapid screening and predictive indicator of the risk of death.

OBJECTIVE: Obesity is recognized as a significant risk factor for diabetes and hypertension. The present study aimed to examine the associations between adults'obesity risk and childhood and parental obesity. METHODS: A total of 204 children aged 6-17 years were recruited in 2002 with an average follow-up period of 13.2 years. Height and body weight were measured by trained staffs. Overweight and obesity were defined based on the Chinese standard for children and adults. T-test, analysis of variance, and Chi-square analysis were used for single factor analysis. Multiple linear and logistic regression analyses were used to perform multifactor analysis. RESULTS: The percentage of non-obese children who grew up to be non-obese adults was 62.6%, and that of obese children who grew up to be obese adults was 80.0%. There was a significant association between childhood body mass index (BMI) and adulthood BMI with a β regression coefficient of 3.76 [95% confidence interval (CI): 1.36-6.16], and between childhood obesity and adulthood obesity with an odds ratio of 5.76 (95% CI: 1.37-24.34). There was no statistical difference between parental obesity at baseline and children's adulthood obesity, after adjustment of confounders. Male participants and those aged 10.0-13.0 years had a higher risk of adulthood obesity with odds ratios of 2.50 (95% CI: 1.12-5.26) and 3.62 (95% CI: 1.17-11.24), respectively. CONCLUSION Childhood obesity is an important predictor of adulthood obesity.

OBJECTIVETo examine the association between habitual sleep duration and obesity among Chinese adults.

METHODSThe association of sleep duration and obesity was investigated among 7,094 community-dwelling Chinese adults. Sleep duration was self-reported. In this study, obesity was defined as follows: body mass index (BMI) ⋝ 28 kg/m2, waist circumference (WC) ⋝ 85 cm in men and ⋝ 80 cm in women, and percent body fat (%BF) ⋝ 25 in men and ⋝ 35 in women. Logistic and quantile regressions were employed to examine relationships of interest.

RESULTSOverall, 6.42% of the participants reported short sleep durations (< 6 h/d) while 14.71% reported long (⋝ 9 h/d) sleep durations. Long sleepers (⋝ 9 h/d) represented a greater frequency of women with obesity [odds ratio (OR): 1.30; 95% confidence interval (CI), 1.02-1.67] and high body fat (1.43, 1.04-1.96) than those who slept 7-8 h/d. An association between long sleep times and higher BMI estimations was found across the 10th-75th percentile of the BMI distribution. Among men, long sleepers (⋝ 9 h/d) presented lower risks of developing abdominal obesity compared with individuals who slept 7-8 h/d (OR = 0.79, 95% CI: 0.44-0.99).

CONCLUSIONOur study suggests that long sleep durations are associated with general obesity in Chinese women but reduced waist circumferences in men. Confirmatory studies are needed to determine the heterogeneous association of sleep time and obesity by gender.

Objective:To observe the protective effect of deproteinized extract of calf blood (DECB)on the ethanol-induced liver injury of the mice,and to preliminaryly discuss its mechanism. Methods:Sixty healthy ICR mice were divided into control group,model group,positive drug group,low,medium and high doses of DECB groups (n=10).By intragastric administration,the mice in control group were given 20 mL·kg-1 saline solution, the mice in low,medium and high doses of DECB groups were administrated with 0.125,0.250,0.500 g·kg -1 DECB,and the mice in positive drug group were administrated with 0.63 g·kg -1 Hugan Tablets;once a day for 30 d. 1 h after the last administration,except control group,the mice in other groups were administrated with one-time grant of 50% ethanol 14 mL·kg -1 ,and fasted for 16 h to establish the models of acute alcohol liver injury.The endurance alcohol time and drunk time of the mice were determined,the activities of aspartate aminotransferase (ALT)and alanine transaminase (AST)activity in serum of the mice were detected,the levels of triglyceride (TG),glutathione (GSH)and malonic dialdehyde (MDA)in liver tissue were determined,and the pathological changes of liver tissue were detected.Results:Compared with model group,the drunk symptoms of the mice in different doses of DECB groups were obviously reduced,the endurance time of the mice in high dose of DECB group and positive drug group was prolonged (P <0.05),and the drinking time was shortened (P <0.05);the ALT and AST activities in serum in mediun and high doses of DECB groups were significantly lower than those in model group (P <0.05).Compared with model group,the MDA and TG levels in liver tissue of the mice in medium and high doses of DECB groups and positive drug group were obviously reduced,and the GSH levels were increased (P <0.05);compared with model group,the pathological damages of liver tissue of the mice in high dose of DECB group caused by ethanol were significantly reduced.Conclusion:DECB can improve ethanol-induced liver injury which may be related to the inhibition of hepatic oxidative stress response.

OBJECTIVETo understand the associations of physical activity domains with metabolic syndrome among a middle-aged Chinese population.

METHODSIn all, 3326 professional adults aged 35-64 years from Beijing and Zhejiang province were recruited with a cluster random sampling method. The Global Physical Activity Questionnaire was modified, and the recommended Asia-Pacific cut-offs of waist circumstance were introduced into the criteria for metabolic syndrome from the Adult Treatment Panel III. A binary logistic regression model was applied to examine the association of all physical activity domains with the risk of the syndrome.

RESULTSParticipants who engaged in domestic activity for ⋜1176 MET-min/week had a 41.6% less chance of having metabolic syndrome [odds ratio (OR), 0.584; 95% confidence interval (CI), 0.480-0.710] than those without this activity. In adjusted models, adults who actively commuted for ⋜33 MET-min/week but <528 MET-min/week had a 25% less chance of having the syndrome (OR, 0.750; 95% CI, 0.582-0.966) than those who did not. No interaction was detected between the two domains of activity and the syndrome.

CONCLUSIONThis study highlighted the independently negative association of traffic and house activity with the prevalence of the syndrome in this sample with a generally low level of moderate activity.

OBJECTIVEObesity is a major risk factor for type 2 diabetes, many indexes can be used to describes obesity and predict diabetes. This research attempts to identify the best indicator of obesity to screening diabetes in Chinese population.

METHODSA cross-sectional data of 8121 subjects aged 35-60 years were included in this research belongs to the Diabetes Appropriate Technology Intervention Study. Anthropometric indicators including body weight, height, waist circumferences (WC), body fat index (BFI) and visceral fat index (VFI) and blood biochemical indicators after an overnight fast [fasting blood glucose, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triacylglycerol] were measured. BMI (body mass index) and Weight to Height Ratio was calculated.

RESULTSSubjects with obesity had a higher risk of physician diagnosed diabetes (OR=2.50, 95% CI 1.83-3.43), new diagnosed diabetes (OR=4.23, 95% CI 2.91-6.15) and pre-diabetes (OR=1.75, 95% CI 1.31-2.34) compared to those with normal Body mass index (BMI). There was a significant trend of increased risk of all diabetes status with increased waist circumference (WC). The waist-to-height ratio (WHtR) yielded the most significant association with new diagnosed diabetes and physician diagnosed diabetes than other indices.

CONCLUSIONCentral obesity is significantly correlated with diabetes. VFI was most correlated with pre-diabetes while WHtR is an efficient screening index than BMI and WC in Chinese community diabetes screening.
