Purpose To summarize the characteristics of computed tomography enteroclysis (CTE) in active ulcerative colitis (UC), and to explore the value of multi-slice CTE in the evaluation of UC. Materials and Methods Thirty-five patients with active UC confirmed by clinical manifestation, colonoscopy and pathology underwent CTE examination in the study. According to the modiifed Mayo-score, the patients were divided into mild group, moderate group and severe group, and the CTE manifestations were compared among the three groups. Results Among 35 patients, 6 patients were in the mild group, 13 in the moderate group, and 16 in the severe group. Submucosal bubbles had signiifcant differences between mild and moderate groups (P<0.05), bowel wall stratiifcation, disappearance of haustra and enlarged mesenteric lymph nodes were signiifcantly different between moderate and severe groups (P<0.05), and engorged vasa recta was significantly different between the 3 groups (P<0.05). However, bowel wall thickening, mural hyperenhencement, narrow lumen and fatty deposits around the rectum showed no difference between the three groups (P>0.05). Conclusion Multi-slice CTE can provide image features of bowel wall, intestinal tube and structures outside intestine in the evaluation of UC, thus it is useful in the diagnosis of active UC as well as in its clinical grading.

Objective To study the features of liver damage caused by anti-TB medicines among patients with TB-HBV co-infection, in order to complement and improve the implementation of DOTs strategy in the region. Methods A historical cohort study was conducted including the process of reviewing and analyzing files of the 781 naive TB patients hospitalized from June 2004 to October 2005. Cases were divided into HBsAg (+) group and HBsAg (-) group. Results The overall damage rate among the 781 investigation cases was 20.74%, including 121 cases (74.69%) in HBsAg (+) group and 41 cases (25.31%) in HBsAg (-) group. Data showed that liver damage rate and average value of ALT and AST of HBsAg (+) group were higher than those in HBsAg (-) group. First case with liver damage in HBsAg (+) group happened on the 7th day of the treatment, while the first liver damage case happened in HBsAg (-) group was on the 16th day. The average onset in HBsAg (+) group was earlier than HBsAg (-) group for 18.09 days. The average time of liver function recovery in HBsAg (+) group was 57.02 days and in HBsAg (-) group it was 27.56 days while the appearance among HBsAg (+) group was 29.46 days later than in HBsAg (-) group. Conclusion The incidence rate of liver damage caused by anti-TB medicines was higher among HBV positive patients than those HBV negative patients. Patients co-infected with HBV infection appeared to be more serious, with higher incidence on liver damage and earlier onset, as well as with the degree of damage to the liver.

ObjectiveTo compare the incidence of respiratory and allergic diseases in children in Xuhui District, Shanghai in 2013 and 2020, and to determine the influencing factors. MethodsAnnual average levels of air pollutants including PM2.5, PM10, O3, SO2, and NO2 were collected and described in Shanghai from 2013 to 2020. A cross-sectional survey was conducted by using a questionnaire among grade 3 to 5 students in a school in Xuhui District, Shanghai, in September 2013 and 2020, respectively. The questionnaire collected variables including living environment, daily habits, family history of respiratory and allergic diseases, and incidence of these diseases in children. Chi-square test was used to determine the difference across respiratory and allergic diseases. Logistic regression was conducted to determine the influencing factors. ResultsA total of 1 398 valid questionnaires were collected (705 in 2013 and 693 in 2020). Compared with 2013, annual average concentrations of PM2.5, PM10, O3, SO2, and NO2 in 2020 significantly decreased. The prevalence of bronchial asthma, bronchitis, persistent cough and persistent expectoration in 2013 were significantly higher than those in 2020 (P<0.05) in Xuhui District. Multivariate analysis showed that severe air pollution, boys, parents with asthma or allergy, parents with higher educational levels, and more allergens in household were the risk factors associated with the incidence of bronchial asthma, bronchitis, allergic rhinitis and atopic eczema (P<0.05). Parents with allergy history, high smoking frequency of family member, and more allergens in household were the risk factors associated with the incidence of persistent cough and persistent expectoration (P<0.05). ConclusionTo 2013,2020 air pollution in Shanghai has been mitigated and prevalence of bronchial asthma and bronchitis of children has decreased. Childhood respiratory and allergic diseases are associated with indoor and outdoor environment, family medical history, and family daily habits.

Objective:To study the expression level of programmed death ligand 1 (PD-L1) in combined hepatocellular-cholangiocarcinoma (cHCC-CCA) and its correlation with the clinical characteristics and prognosis.Methods:The clinical data of 75 patients with cHCC-CCA undergoing surgery in Tianjin Medical University Cancer Institute and Hospital from January 2011 to December 2019, including 61 males and 14 females, with a median age of 55 years (36 to 77). Immunohistochemistry was conducted to determine the PD-L1 expression in tumor. The status of PD-L1 expression, clinicopathological data and prognosis of patients were analyzed.Results:In low-differentiated cHCC-CCA tissues, the proportion of PD-L1 expression (21.1%, 8/38) was higher than that in moderately to well-differentiated cHCC-CCA tissues (2.70%, 1/37, χ2=4.366, P=0.037). The median disease-free survival (DFS) and overall survival (OS)of PD-L1 positive patients were 12.3 and 15.1 months, respectively, lower than those of PD-L1 negative patients (14.4 and 23.3 months). The difference of DFS was statistically significant ( χ2=4.052, P=0.044). In multivariate analysis, major vascular invasion (DFS: HR=1.965, 95% CI: 1.119-3.450, P=0.019; OS: HR=1.781, 95% CI: 1.022-3.105, P=0.042) and lymph node metastasis (DFS: HR=2.451, 95% CI: 1.1033-5.814, P=0.042; OS: HR=2.652, 95% CI: 1.120-6.279, P=0.027) were identified as independent prognostic factors affecting DFS and OS. Conclusions:The proportion of PD-L1 positive is higher inthe low-differentiated cHCC-CCA tissue compared to that in moderately to well-differentiated cHCC-CCA. The major vascular invasion and lymph node metastasis are independent factors affecting the prognosis of patients with cHCC-CCA.

V-raf murine sarcoma viral oncogene homolog B1 (BRAF) is a pro-oncogene, which is one member of the RAF family. Mutated BRAF is found in approximately 8% of human tumors. BRAF gene mutations lead to continuous activation of the mitogen-activatd protein kinase (MAPK) pathway, which resulting in abnormal cell proliferation and tumorigenesis. In recent years, recurrent MAPK signaling mutations were identified in ameloblastoma, among which BRAF-V600E is the most prominent type. This provides new strategies for the targeted treatment of ameloblastoma. This paper reviewed the latest advances in BRAF gene mutation associated with ameloblastoma and its potential clinical significance.
