Autoimmune hepatitis (AIH) is an autoimmune disease characterized by chronic liver inflammation, with a gradually increasing incidence rate, and its social and medical burdens cannot be neglected. Intestinal microecology is becoming a research hotspot in the field of autoimmune disease. In recent years, it has been believed that changes in intestinal microecology can cause changes in autoimmune state, microbial metabolites, and intestinal barrier, which is one of the driving factors for the onset of AIH. Early diagnosis and correct treatment can help to improve the prognosis of AIH patients. This article introduces the characteristics of gut microbiota in AIH patients, elaborates on the impact of intestinal microflora imbalance on the pathogenesis of AIH, and briefly describes related treatment regimens from the perspective of intestinal microecology, so as to comprehensively understand and explain the role of intestinal microecology in AIH and the impact of intestinal microecology balance on the pathogenesis, diagnosis, and treatment of AIH.

Objective@#To analyze the clinical characteristics of cases of novel coronavirus pneumonia and a preliminary study to explore the relationship between different clinical classification and liver damage.@*Methods@#Consecutively confirmed novel coronavirus infection cases admitted to seven designated hospitals during January 23, 2020 to February 8, 2020 were included. Clinical classification (mild, moderate, severe, and critical) was carried out according to the diagnosis and treatment program of novel coronavirus pneumonia (Trial Fifth Edition) issued by the National Health Commission. The research data were analyzed using SPSS19.0 statistical software. Quantitative data were expressed as median (interquartile range), and qualitative data were expressed as frequency and rate.@*Results@#32 confirmed cases that met the inclusion criteria were included. 28 cases were of mild or moderate type (87.50%), and four cases (12.50%) of severe or critical type. Four cases (12.5%) were combined with one underlying disease (bronchial asthma, coronary heart disease, malignant tumor, chronic kidney disease), and one case (3.13%) was simultaneously combined with high blood pressure and malignant tumor. The results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBil) for entire cohort were 26.98 (16.88 ~ 46.09) U/L and 24.75 (18.71 ~ 31.79) U/L, 39.00 (36.20 ~ 44.20) g/L and 16.40 (11.34- ~ 21.15) mmol/L, respectively. ALT, AST, ALB and TBil of the mild or moderate subgroups were 22.75 (16.31- ~ 37.25) U/L, 23.63 (18.71 ~ 26.50) U/L, 39.70 (36.50 ~ 46.10) g/L, and 15.95 (11.34 ~ 20.83) mmol/L, respectively. ALT, AST, ALB and TBil of the severe or critical subgroups were 60.25 (40.88 ~ 68.90) U/L, 37.00 (20.88 ~ 64.45) U/L, 35.75 (28.68 ~ 42.00) g/L, and 20.50 (11.28 ~ 25.00) mmol/L, respectively.@*Conclusion@#The results of this multicenter retrospective study suggests that novel coronavirus pneumonia combined with liver damage is more likely to be caused by adverse drug reactions and systemic inflammation in severe patients receiving medical treatment. Therefore, liver function monitoring and evaluation should be strengthened during the treatment of such patients.

Objective To investigate drug resistance and clinical efficacy of second-line anti-tuberculosis drugs in patients with multidrug-resistant pulmonary tuberculosis.Methods A total of 183 multi-drug resistant pulmonary tuberculosis (MDR-PTB) patients received standard anti-tuberculosis treatment in Zhejiang Provincial Center for Diagnosis and Treatment of Tuberculosis during March 2011 and March 2013.Patients were divided into four groups according to the results of first-line anti-tuberculosis drugs susceptibility test:group A (n =30) resistant to isoniazid (H) and rifamipicin (R) ; group B (n =28) resistant to HR and ethambutol (E) ; group C (n =53) resistant to HR and streptomycin (S) ; groups D (n =72) resistant to HRES.Drug susceptibility tests of second-line drugs kanamycin (Km),protionamide (Pto),paraaminosalicylic acid (PAS) and levofloxacin (Lfx) were performed.Negative conversion rates of mycobacterium tuberculosis in sputum culture were also observed and compared among different groups with x2 test.Results Among 183 MDR-PTB patients,49 cases (26.8%) were resistant to Lfx,which was significantly higher than that of Km (8.7%,n =16),Pto (13.1%,n =24) and PAS (6.6%,n=12) (x2 =37.983,P<0.05).The resistant rate to Lfx in group D was 45.8% (33/72),which was higher than that in group A (2/30,6.7%),group B (6/28,21.4%) and group C (8/53,15.1%) (x2 =14.413,5.047 and 13.087,P <0.05).The occurrence of pre-extensively drug resistance (Pre-XDR) in group D was 34.7% (25/72),which was higher than that in group A (3/30,10.0%) and group C (9/53,17.0%) (x2 =6.499 and 4.852,P < 0.05).Among 157 MDR-PTB patients who received standard anti-tuberculosis treatment for one year,the negative conversion rate of mycobacterium tuberculosis in sputum culture was 87.3% (137/157).The negative conversion rate in group D was lower than that in other groups,but the difference was not of statistical significance (x2 =1.899,P > 0.05).Conclusions The efficacies of second-line anti-tuberculosis drugs vary among MDR-TB patients resistant to different firstline anti-tuberculosis drugs.The sensitivity tests results of the first-line drugs may serve as reference for MDR chemotherapy regimen in lack of test results of second-line drugs.
