Objective To evaluate the effects of stepwise and fine-grained dietary management on the diet control of liver cirrhosis patients complicated with gastrointestinal hemorrhage. Methods Eighty liver cirrhosis patients complicated with gastrointestinal hemorrhage were assigned to experimental group (41 cases) and control group(39 cases) by random digits table method. The patients in experimental group were treated with stepwise and fine-grained dietary management and the patients in control group were given conventional dietary treatments. The compliance diet, mastery of nutrition knowledge, malnutrition risk at admission, intake food, discharge and 2 months after discharge between two groups were monitored. The incidence of rebleeding was tracked after 1 year of discharge. Results The incidence of malnutrition risk in Child-Pugh class C was higher than that in Child-Pugh class B( Z=-4.3, P<0.05 ) . The incidence of malnutrition risk in patients with high education level was lower than that in patients with lower education( r=-0.453, P<0.05 ). The experimental group significantly outperformed control group in mastery of nutrition knowledge at discharge:80(70, 84) points vs. 52(42, 64) points, in compliance diet and malnutrition risk after 2 months after discharge:86(76, 91)%vs. 53(46,57)%, 1(1, 2) points vs. 2(1,3) points, the rebleeding rate in experimental group was significantly less than that in control group within 1 year after discharge 14.6%(6/41) vs. 35.9%(14/39), and the differences were statistically significant between two groups ( χ2 = 4.226- 51.232, all P < 0.05 ). Conclusions Stepwise and fine-grained dietary management can improve the mastery of nutrition knowledge, compliance diet and nutritional status, and reduce the occurrence of rebleeding, worth popularizing further in clinical care of liver cirrhosis patients complicated with gastrointestinal hemorrhage.

Objective:To explore the correlation between glycemic control of type 2 diabetes mellitus (T2DM) patients and brachial-ankle pulse velocity (baPWV). Methods:A community-based cross-sec-tional study was conducted in Beijing, China. Every subject underwent physical examinations, glycated hemoglobin ( HbA1 c ) , blood lipid and baPWV measurements and completed a standardized question-naire. T2DM patients were divided into well controlled and poorly controlled groups according to HbA1c levels. The correlation between glycemic control of T2DM patients and baPWV was analyzed. Results:In this study, 1 341 subjects were recruited, including 733 T2DM patients and 608 non-diabetes sub-jects. Compared with non-diabetes subjects, abnormal baPWV ( baPWV≥1 700 cm/s) rate for T2DM patients was higher (40. 8% vs. 26. 8%, P<0. 001). With HbA1c<6. 5% or <7. 0% as the aim of glycemic control in T2DM patients, the abnormal baPWV rates for non-diabetes subjects, well controlled and poorly controlled T2DM patients were significantly different (non-diabetes vs. HbA1c<6. 5% T2DM vs. HbA1c≥6. 5% T2DM: 26. 8% vs. 32. 8% vs. 42. 6%, P <0. 001; non-diabetes vs. HbA1c <7. 0% T2DM vs. HbA1c≥7. 0% T2DM:26. 8% vs. 36. 1% vs. 43. 4%, P<0. 001). After being ad-justed for gender, age, smoking status, diabetes mellitus family history, T2DM duration, cardiovascular diseases ( CVD ) , waist hip ratio ( WHR ) , systolic blood pressure ( SBP ) , diastolic blood pressure ( DBP) , total triglycerides ( TG) , high density lipoprotein cholesterol ( HDL-C) , and low density lipo-protein cholesterol ( LDL-C ) , the Logistic regression models suggested that glycemic control status of T2DM patients was associated with abnormal baPWV. Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1 c <6 . 5% T2 DM patients and HbA1 c≥6 . 5% T2 DM patients were 0 . 927 (95%CI 0. 560-1. 537) and 1. 826 (95%CI 1. 287-2. 591). Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1c<7. 0% T2DM patients and HbA1c≥7. 0% T2DM patients were 1. 210 (95%CI 0. 808-1. 811) and 1. 898 (95%CI 1. 313-2. 745). Conclusion:The glycemic con-trol status of T2DM patients from communities is significantly associated with baPWV. Poor glycemic con-trol is a risk factor for abnormal baPWV. Keeping HbA1c under control might lower the risk of cardiovas-cular diseases in T2DM patients.

To investigate the effect of ethanolic extract from Artemisia Argyi Folium on blood glucose and blood lipids in diabetic mice, ICR mice were induced by intraperitoneal injection of 35 mg/kg streptozotocin (STZ) and a high-carbohydrate/high-fat diet to construct type 2 diabetes mellitus model. Diabetic mice were randomly divided into three groups: the model group (5 mL/kg 0.5% CMC-Na), the Artemisia Argyi Folium ethanolic extract low-dose group (100 mg/kg ) and high-dose group (400 mg/kg ). During the treatment for 6 weeks, the amount of drinking water and food intake of mice were recorded every day. Blood glucose and body weight were recorded every week. After treatment for 6 weeks, serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C),and oral glucose tolerance (OGTT) were measured. The results showed that the amount of drinking water and food intake of mice significantly decreased (P < 0.01) in the Artemisia Argyi Folium ethanolic extract high-dose group; oral glucose tolerance was significantly improved (P < 0.01) and the contents of TC, TG and LDL-C were significantly decreased in the Artemisia Argyi Folium ethanolic extract low-dose group (P < 0.01). The ethanolic extract from Artemisia Argyi Folium could significantly improve the glucose and lipid metabolic disorder in T2DM mice in a dose-dependent manner.

Objective: To explore the relationship between glycemic control and visceral adiposity index (VAI) among type 2 diabetes mellitus (T2DM) patients.Methods: A community-based epidemiological field study for patients with T2DM aged ≥ 40 years was conducted in China.Every participant underwent physical examinations, biochemical tests of fasting glucose, glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and so on, and a questionnaire, including anthropometric characteristics, lifestyle, disease history, family history, and medication use.Those participants with HbA1c ≥7.0% were classified as the poorly controlled in our analysis of relationship between glycemic control and VAI.Anthropometric characteristics, lifestyle, and biochemical indexes of the participants were compared among the groups of different VAI levels.Logistic models were applied in multiple analysis adjusting for possible confounders.Results: A total of 1 607 patients with T2DM were recruited in our analysis with a mean age of (59.4±8.1) years and an average T2DM duration of (7.0±6.4) years.Among them, 78.3% were on hypoglycemic therapy.The cutoff points of quartiles of VAI were calculated for the males and females, respectively.According to the ascending order of the quartiles of VAI, the participants were divided into four groups, i.e.Q1, Q2, Q3, and Q4.The poor glycemic control rate for these groups were 60.6%, 65.7%, 70.1%, and 71.0%, respectively (Trend χ2=12.20, P<0.001).After adjustment for age, gender, systolic blood pressure (SBP), diastolic blood pressure (DBP), LDL-C, smoking, cardio-cerebral vascular disease (CVD) history, hypoglycemic therapy, T2DM duration, and family history of diabetes, the Logistic regression models showed that the glycemic control rate was significantly associated with VAI levels among the patients with T2DM.Compared with the participants in group Q1, the ORs of poor glycemic control for those in groups Q2, Q3, and Q4 were 1.239 (95%CI 0.918 to 1.672), 1.513 (95%CI 1.117 to 2.050), and 1.535 (95%CI 1.128to 2.088), respectively (trend P=0.003).With each quartile increase in VAI, the OR of poor glycemic control was 1.162 (95%CI 1.054 to 1.282).Conclusion: The glycemic control among the patients with T2DM is significantly associated with VAI.High level of VAI is an indicator of poor glycemic control.

Objective: To study the difference in the flora structure and gene function of dental plaque in caries-free and caries-active preschool children by 16S rRNA sequencing. Methods: After oral examination of 96 preschool children aged 3-6 years, they were divided into 3 groups according to their decayed, missing and filled surface (dmfs) index: group CF with no caries (n=31), group ECC with moderate early childhood caries (n=29) and group SECC with severe early childhood caries (n=36). Dental plaques were collected, and DNA was extracted and then underwent metagenomic sequencing by Illumina HiSeq 2 500. The bacterial community structure was analyzed by Qiime. Results : A total of 12 phyla, 31 classes, 31 orders, 50 families, 92 genera and 1 104 species were found in the dental plaque samples of the three groups, most of which belonged to 9 dominant genera, including Streptococcus, Veillonella, etc. The microbial diversity of the dental plaques in the three groups was similar (P > 0.05). Veillonella, Lactobacillus, Megasphaera, and Scardovia in the SECC group were significantly higher than those in the other two groups. There was a significant correlation between the decayed, missing and filled surface (dmfs) index and the genus. Bifidobacterium, Veillonella, Lactobacillus had a positive correlation with the dmfs index, while Eikenella had a negative correlation with the dmfs index. Indicator species analysis showed that Atopobium, Veillonella, Megasphaera, Scardovia, Lactobacillus and Bifidobacterium had high indicative values in the SECC group. Conclusion There are significant differences in plaque microbiota among preschool children with different caries sensitivities. Veillonella, Megasphaera, Scardovia, Lactobacillus, Bifidobacterium and Atopobium may be the indicator genera of severe early children caries.
