Autoimmune hepatitis (AIH) is the first liver disease which has proved responsive to gluc()orticoids,and the standard therapeutic method is hormone combined with azathioprine.Given that some patients fail to reach the standard of immunosuppressive therapy,and the long-term use of immunosuppressive therapy has many adverse effects,it is necessary to reasonably use anti-inflammatory and liver-protecting drugs to minimize the dose of immunosuppressants,control liver inflammation,reduce the damage of liver cells,and delay the progression of the disease.This paper reviews the advances in the application of anti-inflammatory and liver-protecting drugs in the treatment of AIH,in order to help clinicians make rational decisions.

OBJECTIVE:To study the kinetics of percutaneous permeability of baicalin in nude mice.METHODS:The transdermal constants of baicalin via nude mouse’s skin were determined,and the effects of stratum corneum on the kinetics studied.RESULTS:The kinetic equation of baicalin via nude mouse’s skin was Q=76.07T 1/2 -32.11,while the kinetic equa?tion of baicalin via nude mouse’s skin without stratum corneum was Q=134.25T 1/2 +29.07,and there was baicalin exuded from skin after detachment of patch.CONCLUSION:The kinetics of the patches is accord with the characteristics of frame?work type;the main barrier for baicalin permeance is stratum corneum and the skin without stratum corneum could store drugs.

Objective To observe the relationship between degree of venous injury and the indwelling time by injection of chemotherapy drugs with intravenous catheter system. Methods Totally 43 New Zealand rabbits were selected as the study sample. Among them, three rabbits were chosen by lot as a blank control, the others were evenly divided into two groups randomly. The veins at the edges of the two ears were taken out as the tested blood vessels for the infusion with intravenous catheter system. The two groups were injected respectively with physiological saline and chemotherapy drugs once daily, and then blocked with heparin salt water. After intraperitoneal anaesthesia, pathological sections were prepared by taking live samples from the ear vein where intravenous catheter system puncturing on the 2nd, 4th, 6th,8th and 10th day of transfusion. And inflammation and thrombosis in the vein had been observed under the light microscope. Results In the same indwelling time, the inflammatory response of the two groups was compared: no difference on the 2nd day; difference was seen on the 4th、6th and 8th day; but again no difference on the 10th day. Thrombosis compared: no difference on the 2nd, 4th day, but difference was seen on the 6th, 8th and 10th day. Conclusions Chemotherapy drugs has a strong irritant on blood vessels.The indwelling time should not be too long, generally advisable 2 days,even if no abnormal response is observed locally by the naked eye.

Objective:To explore the structure of maternal verbal scaffolding features and develop a questionnaire on Mother's language scaffolding characteristics, so as to provide a quantitative, convenient and economical self-assessment tool for describing maternal verbal scaffolding features.Methods:On the basis of qualitative research and literature research, a questionnaire survey was conducted among 704 mothers of preschool children. After item analysis and exploratory factor analysis, a formal questionnaire was formed. Two weeks later, 106 mothers were retested to collect test-retest reliability data. Preschool children's expressive vocabulary checklist was used as external criterion.Data were analyzed by SPSS 18.0 and Amos 21.0.Results:(1)The formal questionnaire includes 28 items with two factors-detailed support factor and control rejection factor, the internal consistency coefficients of the two factors were 0.849 and 0.811, the project load was from 0 .482 to 0 .701, and the variance contribution rate was 40.36%.(2) AMOS 21.0 was used for confirmatory factor analysis, indicating that the two-factor structure met the requirements of psychometrics.( χ 2/ df=1.96, RMSEA=0.05, NFI=0.86, CFI=0.90, IFI=0.89). (3)The results of two-factor text-retest reliability were 0.840 and 0.871 as well as the results of split-half reliability was 0.801.The internal consistency reliability was 0.740.The external validity analysis showed that the mother's education level was positively correlated with factor Ⅰ( r=0.288, P=0.000), but not with factor Ⅱ( r=-0.091, P=0.052). There was significant difference in factorⅠbetween mothers with expressive vocabulary development delay children (52.22±10.56) and non delayed children (57.71±7.51) ( t=-5.07, P=0.000). There also was a significant difference in factor Ⅱ between mothers with expressive vocabulary development delay children (37.12±10.09) and non delayed children (31.53±8.59) ( t=4.61, P=0.000). (4)There was no significant difference in the characteristics of language scaffolding between boys(factorⅠ(58.08±8.14), factorⅡ(32.86±9.51)) and girls' mothers(factorⅠ(56.93±8.20), factorⅡ(31.42±8.48)). Analysis of the sample groups showed that age did not affect the verbal scaffolding features of preschool children's mothers( F1=1.633, P1=0.181; F2=0.758, P2=0.518). Conclusion:There are two factors in the questionnaire of the verbal scaffolding features questionnaire, which meet the criteria of psychometrics.The questionnaire of the verbal scaffolding features questionnaire is suitable for evaluating the characteristics of language scaffolding of mothers of preschool children aged 3-6.

Objective:To explore the role of receptor-interaction protein 3 (RIP3) in regulating the infiltration of monocytes/macrophages into the liver in autoimmune hepatitis (AIH).Methods:From January to June in 2018, at Department of Gastroenterology and Hepatology, Tianjin Medical University General Hospital, 10 AIH patients who underwent liver biopsy were enrolled, and at the same time, 5 age and gender matched individuals with normal liver function and hepatic cyst were selected as control. The infiltration of monocytes/macrophages in the liver tissues was observed by immunofluorescence detection in the patients with AIH and controls. Raw264.7 macrophages were divided into control group, lipopolysaccharide group and lipopolysaccharide+ RIP3 inhibitor GSK872 (GSK872) group. The expression of RIP3, mixed lineage kinase domain like pseudokinase ( MLKL), tumor necrosis factor ( TNF)- α, interleukin ( IL)-6, IL-1 β, nod-like receptor protein 3 ( NLRP3), CC motif chemokine ligand ( CCL)2 and CCL5 at mRNA levels were detected by quantitative polymerase chain reaction (qPCR). Raw264.7 macrophages were also divided into control group, lipopolysaccharide group and lipopolysaccharide + dexamethasone group. The relative expression of TNF- α, NLRP3, RIP3 and MLKL at mRNA level in macrophage were detected by qPCR. Twenty-four 6-week-old female C57BL/6 mice were chosen to establish AIH mice model and were randomly divided into control group, concanavalin A (ConA) group, ConA+ dexamethasone group and ConA+ GSK872 group (6 mice in each group). After the mice were executed, the peripheral blood and liver tissues were collected. The histopathology of mice liver were observed and the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured. The expression of CCL2 and CC motif chemokine receptor 2 ( CCR2) at mRNA level were detected by qPCR. The proportion of macrophages in mice livers were analyzed by flow cytometry. The independent sample t test and one-way analysis of variance were performed for statistical analysis. Results:The percentages of CD68 positive macrophages and MAC387 positive infiltrated mononuclear macrophages in livers of AIH patients were both higher than those of controls ((0.84±0.21)% vs. (0.09±0.03)%, (0.79±0.13)% vs. (0.03±0.01)%), and the differences were statistically significant ( t=3.00 and 4.84; all P<0.05).
