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 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 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 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.

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 the improving effects of Shenshao decoction on myocardial structure and function in diabetic cardiomyopathy,and its effect on expression of TLR4/MyD88-dependent pathway signal in diabetic cardiomyopathy.Methods Diabetes mellitus was induced in 8-week-old male Wistar rats by a single intraperitoneal injection of streptozotocin.The changes of plasma myocardial enzyme (CK, LDH) and high sensitive C reactive protein (hsCRP) were measured.Cardiac function was measured by left ventricular intubation.Hematoxylin and eosin staining and electron microscopy were used to observe the changes of myocardial morphology and ultrastructure in rats.Expression of Toll-like receptor 4(TLR4), myeloid differentiation protein 88(MyD88), and nuclear factor-κB P65(NF-κB P65) were tested by immunohistochemistry.Results After 6 weeks of treatment, the left ventricular diastolic and systolic functions were obviously improved;the degrees of myocardial fibers and mitochondrial damage were obviously relieved;the content of CK, LDH and hsCRP decreased (P< 0.05), and hsCPR was positively correlated with CK and LDH (r=0.823,r=0.819,P < 0.05).The expressions of TLR4, MyD88, NF-κB P65 were significantly decreased (P< 0.05).There was no significant difference in the above mentioned indicators between the control group and control+Shenshao decoction group (P> 0.05).Conclusions Shenshao decoction can reduce the myocardial injury in diabetic cardiomyopathy and improve cardiac diastolic and systolic functions.The mechanism may be related to attenuated inflammation by TLR4/MyD88 dependent signaling pathway.

Objective To observe the clinical efficacy of needling a group of acupoints for choke plus rehabilitation training in treating post-stroke deglutition disorder.Method Ninety patients with post-stroke deglutition disorder were randomized into a treatment group and a control group, 45 cases in each group. In addition to the conventional treatment, the control group also received swallowing rehabilitation training, and the treatment group received acupuncture ata group of acupoints for chokeas the major intervention(Aqiang point, Zhiqiang point, Tunyan point, Tiyan point and Fayin point, all extra) besides the intervention given to the control group, both for 3 successive treatment courses. Before and after theintervention, the National Institute of Health Stroke Scale (NIHSS), Videofluoroscopic Study (VFSS), post-stroke swallowing scale of traditional Chinese medicine (TCM) (TCM scale for short), and the occurrence rate of relevant complications were comparedbetween the two groups.Result The total effective rate was 97.8% in the treatment group, significantly higher than 84.4% in the control group (P<0.05); the scores of NIHSS, VFSS and TCM scale in the treatment group were superior to those in the control group (P<0.05);the NIHSS, VFSS and TCM scale scores in the treatment group were superior to those in the control group after the intervention (P<0.05);24 cases in the control group presented complications versus 8 cases in the treatment group (P<0.05).Conclusion Acupuncture at the points group for chokepredominantlyplus rehabilitation training can effectively improve post-stroke deglutition disorder and reduce the occurrence of complications, with satisfactory safety and consistency.
