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 investigate the therapeutic effect of Shenmai injection(SMI)on neonatal hypoxic-ischemic encephalopathy(HIE)and it's possible mechanism.Methods 45 neonates with HIE were randomly divided into the SMI treatment group and routine treatment group.At the basic of routine treatment,the SMI treatment group was treated with 10 ml SMI added into 10% GS 30~50 ml via injecting into veins once a day for 7~10 d.The levels of serum S-100?,NSE were measured at 1 d,3 d,6 d after treatment.The development quotients(DQ)was evaluated at 3-month-old infants.Results Compared with routine treatment group,symptoms of nervous system in SMI treatment group were recovered obviously faster,the hospitalization time was shorter(all P

Objective To establish the topotecan(TPT)-resistant cell line of human oophoroma (SKOV3/TPT), and to investigate its biological features. Methods To simulate the condition in clinical chemotherapy, drug resistant SKOV3/TPT cell line of human oophoroma was established by challenging SKOV3 with a large dose of TPT (2160ng/ml). Drug sensitivity was assessed by MTT assay. Light microscopy, electronic microscopy, trypan blue staining rejection, and cell counting were employed to determine the biological features of the cell line. Flow cytometry (FCM) was used to study the cell cycle distribution, the accumulation of intracellular drug, and the expression of P glucoprotein (Pgp). Results SKOV3/TPT cells were established successfully, and the resistance index (RI) was 10.67. They showed an obvious cross-resistance to CPT-11, MX and VCR, but still sensitive to taxol, cis-platin, VP16, MTX and 5-Fluorouracil. Comparing with the parent cells, their morphology was unchanged, but multiplication time was prolonged. The apoptosis rate and the proportion of G2+M phase cells of resistant cells were significantly higher than that of their parent cells (P

Objective To explore the effects of ultraviolet on DNA damage in keratinocytes and to observe the protective role of resveratrol for the cells. Methods Comet assay was employed to evaluate the damage after radiation with different doses of UV rays (UVA, UVB and UVC) of 0, 10, 30, 50, 70 and 90 mJ/cm2, and the effects after pretreatment with various concentrations of resveratrol under irradiation with 30 mJ/cm2. Results UVA irradiation (0 ~ 90 mJ/cm2) had no significant effects on HaCaT cells. However, TailDNA%, TailLength, CometLength, TailMoment and OliveTailMoment showed both UVB and UVC induced DNA damage in a dose-de-pentent manner. UVC was more harmful than UVB at the same dose. Conclusions The DNA breakage induced by UVB and UVC is dose-dependent. As compared with UVB, UVC is more harmful to HaCaT cells. Resveratrol exerts a protective effect in HaCaT cells irradiated by UVB or UVC.

Objective To study the role of suppressor of cytokine signaling ( SOCS ) in the pathogenesis of primary biliary cirrhosis( PBC),the levels of SOCS protein and the changes of function of dendritic cell(DC) were respectively observed from PBC patients.MethodsThe study population consisted of 10 patients of PBC and 8 healthy controls.Phenotypic analysis of cultured peripheral blood mononuclear cells (PBMC)-derived DC was performed by flow cytometry (FCM),such as CD83,CD86 and human leukocyte antigen DR (HLA-DR).The levels of interleukin-10 (IL-10),interferon-γ( IFN-γ) and IL-12 in culture supematant of DC were measured by enzyme linked immunosorbent assay ( ELISA ).The protein levels of SOCS1 and SOCS3 were detected by Western blot ( WB ).The features of changes in these parameters were analyzed between the two groups.ResultsThe expression of CD83,CD86 and HLA-DR in PBC patients were ( 79.4 ± 4.8 ) ％,( 86.5 ± 6.3 ) ％ and (90.0 ± 3.5 ) ％,which were significantly higher than those in healthy control group[ (68.3 ±4.1 )％,(74.2 ±6.3)％ and (83.6 ±7.6)％ ],respectively (t =5.340,4.120,2.514,P ＜0.05).The levels of IL-12 and IFN-γin PBC patients were (53.5 ± 11.1)and (32.0 ±9.0) ng/L,which were significantly higher than those in healthy control group[ (32.1 ± 10.7) and (15.4 ± 8.1 ) ng/L; t =4.123,3.818,P ＜ 0.01 ].There were not any significant difference of IL-10 level between PBC patients [ (7.0 ± 4.6) ng/L ] and the healthy controls [ ( 5.8 ± 4.2) ng/L; t =0.563,P ＞ 0.05 ].The proteins levels of SOCS1 and SOCS3 in PBMC-derived DC from PBC group were decreased significantly than those in healthy control group.ConclusionsThe results suggest that the PBMC-derived DC in PBC patients has greater ability of potent maturation and antigen presentation function.The decreased expression of SOCS levels may be associated with the excessive immunological reaction and the breakdown of self-tolerance.

We carried out a new unit-based method in the teaching process of epidemiology for improving undergraduate prevention-oriented medical students' comprehensive ability. The new method integrated heuristic teaching and case teaching, and focused reform on the system of teaching and assessment. The results showed new teaching method can significantly improve students' capacity of analysis and oral expression, and contributes to the comprehensive ability.

In the last decade, along with the development of taxonomy research in marine-derived actinobacteria, more and more halogenated natural products were discovered from marine actinobacteria. Most of them showed good biological activity and unique structure compared to those from land. The special halogenation mechanism in some compounds' biosynthesis has drawn great attention. So in this review, we focus on the halogenated natural products from marine actinobacteria and their halogenation mechanisms.

Objective To investigate whether serum level of low-density lipoprotein cholesterol can predict the expan?sion of hemorrhage growth in elderly male patients with acute hypertensive intracerebral hemorrhage. Methods Patients (n=108) who visited our hospital with from June 2012 until May 2014 spontaneous hypertensive intracerebral hemorrhage with?in 6 hours of onset which is confirmed by initial computed tomography (CT) were sent to repeated CT within 24 hours of on?set. All selected patients were divided into the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. Clinical data of these 2 groups were compared and the relationships of hematoma growth and its risk factors were analyzed. Results Baseline blood pressure, the level of blood glucose, PT, APTT, FIB, PLT and hemorrhage volume did not differ significantly between the LDL-C≥2.49 mmol/L group and LDL-C<2.49 mmol/L group. The ratio of hemorrhage growth in LDL-C<2.49 mmol/L group was significantly higher than that in LDL-C≥2.49 mmol/L group (34.21%vs 11.43%). Multiple logistic regres?sion analysis showed that LDL-C<2.49 mmol/L was the only risk factor contribute to hemorrhage growth. Conclusion Pa?tients with LDL-C<2.49 mmol/L in acute intracerebral hemorrhage are of high risk of hemorrhage growth so early attention and appropriate procedure are needed to prevent or slow its growth.
