Objective To investigate the value of double-balloon endoscopy (DBE) and multi-slice CT enteroclysis (MSCTE) in diagnosis of Crohn's disease (CD) in small intestine. Methods DBE and MSCTE were performed in 71 patients with suspected Crohn's disease in small intestine. The two methods were compared in terms of diagnosis, extents of disease, existance of complications and activity of the disease according to the pathologic findings and the outcome of follow-up. Results The diagnostic yields of DBE and MSCTE were comparable with no significant difference (χ2=2.29, P> 0.05). The positive and negative likelihood ratios were 22.5 and 0. 022 in DBE respectively, and were 1.6 and 0. 240 in MSCTE respectively. The results of DBE was consistent with MSCTE in diagnosis of mild bowel stenosis, but was inconsistent with MSCTE in diagnosis of moderate-severe bowel stenosis (χ2=11.298, P=0.001). The concordance of two methods in diagnosis of disease activity was 95.8%. Conclusions The first choice in diagnosis of small bowel CD is DBE. The combination of two methods will be helpful in diagnosis and evaluation of CD severity.

Results Totally,19 974 patients participated in this study,and 17 345 valid questionnaires were retrieved with a return rate of 86.84%.Of them,122 were found to have vitiligo.The prevalence and standardized prevalence of vitiligo was 0.70% and 0.56% in all patients,0.95% (75) and 0.69% in male patients and 0.50% (47) and O.45% in female patients.respectively.A significant elevation was observed in the prevalence of vitiligo in males than in females (P<0.01).The prevalence of vitiligo was increased with age and peaked in patients aging from 60 to 69 years and those over 70 years.The age at onset of vitiligo varied from 0 to 19 years in 21.85% of these patients,from 20 to 49 years in 47.05%.The most connnon type was focal vitiligo,which accounted for 36.06%,while the rarest type wag segmental type (2.46%).The pesitivity rate of family history of vitiligo was 9.84% in patients and 1.31% in community population (P<0.01).About 31.97% of the patients complained of negative influence of vitiligo on quality of life.Conclusions The standardized prevalence of vitiligo is 0.56%in 6 provinces from China.Males seem to have a higher prevalence of vifiligo than females.

Objective:To explore the genotype and clinical phenotype characteristics of patients with pancreatic agenesis caused by GATA6 gene mutations and to improve the clinical understanding of pancreatic agenesis.Methods:The clinical data of a newborn with pancreatic agenesis admitted to the Second Hospital of Shandong University were retrospectively analyzed. Relevant literature published until October 31, 2022, were retrieved from China National Knowledge Infrastructure, Wanfang Database, VIP Database, Chinese Medical Journal Full Text Database, PubMed, Embase and SCI Database with the terms of "pancreatic agenesis", "GATA6", "pancreatic agenesis/hypoplasia" and "GATA6 Translation Factor". The characteristics of gene variants and clinical manifestations of patients diagnosed with pancreatic agenesis caused by GATA6 gene mutation were retrieved and summarized.Results:This case was a full-term male infant who developed insulin dependent hyperglycemia and fatty diarrhea 2 d after birth, accompanied by intrauterine growth restriction, congenital heart disease, and cryptorchidism. Genetic testing showed a novel heterozygous mutation of GATA6 (c.1366C>T) which was consistent with the autosomal dominant inheritance pattern. The phenotype and genotype between the proband and his parents were consistent with the cosegregation. The ACMG mutation was rated as pathogenic variant. Intravenous infusion of insulin, subcutaneous injection of insulin, or long-acting insulin were not effective. After continuous subcutaneous pumping of aspartic insulin combined with oral pancreatic enzyme replacement therapy, the infant's condition was improved and discharged. Follow up to age of 15 months, the patient still relied on continuously subcutaneous pump to control blood glucose, pancreatic exocrine function was back to normal, and the development was generally normal. A total of 59 cases were reported in 22 articles, with the case from our hospital, there were 60 patients in total. Among them, 47 were probands and 13 were family members, about 61.7% (29/47) of which were de novo mutations. There were 39 variants, of which 28.2% (11/39) were missense mutations and 71.8% (28/39) were functional deletion variations. Mutations of GATA6 gene had a broad phenotype spectrum. The phenotypes mainly included neonatal diabetes mellitus ( n=39) and pancreatic exocrine insufficiency ( n=39). Other extra-pancreatic features included different types of congenital heart disease ( n=54), congenital biliary abnormalities ( n=23), intestinal developmental disorders ( n=16), neurocognitive disorders ( n=18) and endocrine abnormalities ( n=15). Conclusions:The heterozygous variations of GATA6 gene lead to pancreatic hypoplasia and a broad phenotype spectrum. The pancreatic phenotypes mainly include neonatal diabetes mellitus and pancreatic exocrine insufficiency, and extra-pancreatic phenotypes include congenital heart disease and other developmental abnormalities.

【Objective】 To reveal possible mechanisms of miRNA in diabetic hepatopathy through bioinformatics method. 【Methods】 Subset data of miRNA and their matched mRNAs in the liver of STZ-induced diabetic mice and the normal liver tissues of congenial mice by detecting on microarrays were collected from GEO database； information from the database and bioinformatics analysis were applied to mine a batch of miRNAs in diabetic hepatopathy and targeted mRNAs regulated. Then qRT-PCR was used to verify the expressions of miRNAs in diabetic liver from 20 STZ-treated Kunming mice and 10 normal homologous mice. 【Results】 Via detection and analysis， miRNAs differentially expressed （including 96 up-regulated and 77 down-regulated） were significantly obtained. Groups of miRNAs and their effectors （mRNAs） that may be related to the pathological process of diabetic liver disease in mice were screened by GO and KEGG enrichment analyses， combined with relevant protein annotations in the databases and references. The expressions of miR-200a-3p， miR-200b-3p and miR-222-3p in the mice’s liver tissue detected by qRT-PCR were significantly down-regulated. In addition， the expressions of related effector genes CERS6， MYBL1， SCD2， SLCO1A4 and PLK2 were up-regulated， while the expressions of ACSS2， BCL6 and SLC10A2 were down-regulated. 【Conclusion】 The variation trend of those candidate miRNAs in mouse diabetic liver compared with that in control livers was consistent with that of the previous studies and prediction， which revealed their potential molecular regulation in this disease process.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.
