To analyze the relationship between serum vitamin A and E levels and asthma risk in children aged 1-14 years. Based on a multi-center case-control study design, general information and vitamin A and E test data were collected from asthmatic children in the respiratory outpatient departments of four medical institutions in Hunan Province and control children undergoing health check-ups in the child healthcare departments during the same period from July 2017 to October 2019.After 1∶1 matching age and gender using propensity scores, a total of 2 454 research subjects were included. 1 730 boys and 724 girls, with an age range of 1-14 years, a median age of 3 years and a mean age of (3.58±2.83) years. The levels of vitamin A and E in the asthma group and the control group were compared. Binary Logistic regression was used to analyze the association between vitamin levels and asthma, and stratified analysis by age and gender was conducted. The results showed that a total of 3 447 research subjects were initially included in this study, and 2 454 research subjects were included after propensity scores matching (PSM). After matching, there was no statistically significant difference in age and gender between the two groups ( χ2=0.00 ,P>0.05), and the standardized mean difference (SMD) values were all less than 10%.The levels of vitamin A and E in the asthma group were significantly lower than those in the control group [(0.32±0.09)mg/L vs.(0.34±0.08)mg/L, t=4.94 ,P<0.001;(8.90±2.47)mg/L vs.(9.19±2.58) mg/L, t=2.79 ,P=0.005]. Compared to the normal vitamin A group, the high-risk subclinical deficiency group ( OR=1.53, 95% CI: 1.28-1.83) and the subclinical/clinical deficiency group ( OR=2.68, 95% CI: 1.81-3.97) were significantly positively associated with asthma risk. Compared to the normal vitamin E group, the vitamin E insufficient group was significantly associated with increased asthma risk ( OR=1.28, 95% CI: 1.03-1.57). Subgroup analysis revealed that subclinical/clinical vitamin A deficiency was significantly associated with increased asthma risk across all age groups and both genders (all P<0.05), whereas vitamin E insufficiency was only associated with higher asthma risk in the 1-3 age group and among girls ( P<0.05).In conclusion, subclinical or clinical deficiency of vitamin A may significantly increase the risk of asthma. Vitamin E deficiency is mainly associated with an increased risk of asthma in younger age groups (1-<3 age group) and girls.

Type 2 diabetes mellitus is a common metabolic disease characterized by chronic elevated serum glucose level and abnormal lipid metabolism in the body.The age of onset gradually becomes younger,and the prevalence of overweight/obesity is increasing rapidly,which increases the difficulty of controlling blood glucose and affects the quality of life.Based on the Concept of Wholism of TCM,losing weight and reducing glucose can be achieved through correcting physical bias,regulating intestinal flora and improving insulin resistance.This article summarizes the current diagnosis and treatment of overweight/obese young adults with type 2 diabetes mellitus in four aspects:population characteristics,lifestyle intervention management mode,western medicine treatment and TCM treatment,with a purpose to provide reference for the standardized treatment of traditional Chinese medicine to prevent the disease before it develops and prevent the disease from changing in the future.

Objective:To develop a mesenteric creeping fat index (MCFI) based on CT enterography (CTE) to characterize the degree of creeping fat wrapping around the inflamed gut in Crohn disease (CD), and to assess the relationship between MCFI and the inflammatory intestinal stricture.Methods:From December 2018 to July 2019, the patients with CD who underwent surgery in the First Affiliated Hospital of Sun Yat-Sen University were prospectively collected. The extent of perienteric mesenteric vessels wrapping around the gut was reconstructed to develop MCFI based on CTE images. The intestinal stricture index was obtained by calculating the ratio of the maximal upstream luminal diameter divided by the minimum luminal diameter apparent within the stricturing region. Using region-by-region correlation between CTE and surgical specimen, creeping fat score in intestinal specimen was obtained by assessing the extent of creeping fat wrapping around the resected bowel segment, and HE staining was performed on the bowel specimen corresponding to creeping fat to obtain the pathological inflammatory score. The Spearman correlation analysis was used to evaluate the correlation between MCFI, creeping fat score in intestinal specimen, and inflammatory score, intestinal stricture index. The ROC curve analysis was used to assess the accuracy of MCFI in distinguishing moderate-severe and mild inflammatory bowel walls.Results:Totally 30 CD patients were enrolled. The creeping fat score in intestinal specimen positively correlated with pathological inflammatory score ( r s=0.403, P=0.027) and with intestinal stricture index ( r s=0.642, P<0.001). MCFI positively correlated with creeping fat score in intestinal specimen ( r s=0.840, P<0.001), with pathological inflammatory score ( r s=0.497, P=0.005), and with intestinal stricture index ( r s=0.599, P<0.001). ROC analysis showed that the area under the curve of MCFI for differentiating moderate-severely from mildly inflammatory bowel walls was 0.718 (95%CI 0.522-0.913). Using MCFI≥4 as a cutoff value, the sensitivity and specificity were 81.8% and 47.4%, respectively. Conclusions:There was a correlation between creeping fat and inflammatory intestinal strictures in CD. MCFI can non-invasively depict the degree of creeping fat wrapping around the gut and assess the inflammatory intestinal stricture.

Objective:To explore the diagnostic efficacy of nomogram based on multi-parameter MRI for assessment of bowel fibrosis in patients with Crohn disease（CD).Methods:The clinical and imaging data of CD patients diagnosed by surgical histopathology in the First Affiliated Hospital of Sun Yat-sen University from June 2015 to March 2018 were prospectively collected. All the patients underwent conventional MRI and diffusion kurtosis imaging（DKI) within 2 weeks before surgery. Patients who underwent surgery between June 2015 and September 2017 were included in the model building group, and those who underwent surgery between October 2017 and March 2018 were included in the model validation group. We measured the apparent diffusion coefficient（ADC) from monoexponential model of diffusion-weighted imaging（DWI), apparent diffusional kurtosis（K app), and apparent diffusion for non-Gaussian distribution（D app) from non-Gaussian DKI model, and observed T 2WI signal intensity and enhancement pattern of the same segment. One to three intestinal specimens per patient were stained with Masson′s trichrome for the histological grading of fibrosis. Correlations between qualitative/quantitative MRI indexes and histological grades were evaluated using the Spearman rank test. Multivariate logistic regression analysis was performed to identify independent factors to be included into the nomogram for predicting the degree of bowel fibrosis and its diagnostic performance was assessed by internal and external validation. Results:A total of 40 CD patients were included, including 31 in the model construction group and 9 in the model verification group. A total of 81 intestinal specimens from 31 patients were graded as none-to-mild bowel fibrosis（ n=32) and moderate-to-severe bowel fibrosis（ n=49) according to a scoring system of fibrosis. In the training cohort, the K app value of moderate-to-severely fibrotic bowel walls was significantly higher than that of none-to-mildly fibrotic bowel walls, and the D appand ADC values of moderate-to-severely fibrotic bowel walls were significantly lower than those of none-to-mildly fibrotic bowel walls（ Z=-5.999, -4.521 and -3.893; P<0.001). There was no significant difference in T 2WI signal intensity or enhancement pattern between these two groups（χ2=1.571 and 0.103; P>0.05). Moderate and mild correlations of histological fibrosis grades with K appand D app( r=0.721 and -0.483; P<0.001), and a mild correlation with ADC（ r=-0.445, P<0.001) were found. Independent factors derived from multivariate logistic regression analysis to predict the degree of bowel fibrosis were K app and D app. Internal and external validation revealed good performance of the nomogram with concordance index of 0.901（95% confidence interval, 0.824-0.978) and 1.000, respectively, for differentiating none-to-mild from moderate-to-severe fibrosis. Conclusion:The DKI-based nomogram can be used to evaluate the bowel fibrosis in CD patients and provides a visual and simple prediction method for clinic.
