Objective To investigate the effects of the zinc finger protein A20 on LPS-TLR4 signaling pathways in severe acute pancreatitis(SAP) rats.Methods 24 SD rats were randomly divided into 3 groups:group A(the sham operation group),group B (the SAP group),group C (the SAP group treated with LPS).SAP model was induced by retro-injection of intraductal 5％ sodium taurocholate into the biliary-pancreatic duct as previously described.The protein expression of A20,TLR4,NF-κBp65 and p38MAPK in pancreatic tissues was evaluated by immunohistochemistry.Results The positive area of A20 in pancreatic tissues was decreased in group B and group C compared with that in group A (t =17.234,19.698,all P ＜ 0.05).On the contrary,the expression of TLR4,NF-κBp65 and p38MAPK in pancreatic tissues were up-regulated(t =15.909,20.432,16.543,18.629,22.105,19.006,all P ＜ 0.05).A20 was decreased in group C than that in group B (t =14.894,P ＜ 0.05),while TLR4、NF-κBp65 and p38MAPK were increased in group C than those in group B (t =14.047,15.582,17.070,all P ＜0.05).Conclusion The expression of A20 reduced and TLR4,NF-κBp65 and p38MAPK enhanced in the pancreas of rats with SAP,which indicated that A20 inhibited LPS-TLR4 signaling pathways which play important roles in the pathogenesis of SAP.

Marine traditional Chinese medicine (MTCM) is an important part of Chinese medicine (CM),there are some differences in understanding of the current literature and the extension of the connotation of marine medicine,which leads to the definition dispute of MTCM,hindering clinical application and further development of MTCM.In this study,we explored the concept of MTCM in literature,discussed the attributes of ocean marine CM,summed up the differences between the land CM and MTCM over variety characteristics,effect of drug composition characteristics and biological activity characteristics,and discussed the connotation and extension of MTCM from three aspects of theoretical basis and the effect and source of the drug,leading to the formation of the narrow and broad concept of MTCM.The five kinds of disputes in the definition of MTCM were discriminated according to the concept and connotation,which provided a theoretical basis for the definition and the research of MTCM.Moreover,we also defined the English translation and its abbreviation as Marine Traditional Chinese Medicine (MTCM).

A sesquiterpene synthase (AsSS4) full-length open reading frame (ORF) cDNA was cloned from wounded stems of Aquilaria sinensis by RT-PCR method. The result showed that the ORF of AsSS4 was 1,698 bp encoding 565 amino acids. Prokaryotic expression vector pET28a-AsSS4 was constructed and transformed into E. coli BL21 (DE3) pLysS. Recombinant AsSS4 protein was obtained after induction by IPTG and SDS-PAGE analysis with a MW of 64 kD. Enzymatic reactions using farnesyl pyrophosphate showed that recombinant AsSS4 protein purified by Ni-agarose gel yielded five sesquiterpene compounds, cyclohexane, 1-ethenyl-1-methyl-2, 4-bis(1-methylethenyl)-, β-elemene, α-guaiene, α-caryophyllene and δ-guaiene. This paper reported the first cloning and functional characterization of AsSS4 gene from A. sinensis, which will establish a foundation for future studies on the molecular mechanisms of wound-induce agarwood formation in A. sinensis

Objective To investigate anti-hypertension threapy on seasonal variability of blood pressure,urinary 8-OHdG levels in essential hypertension in order to provide a basis for seasonal antihypertensive treatment.Methods Fifty hypertensive patients admitted the hospital of Erdos Clinical Medical College of Inner Mongolia Medical University at summer 2013 were selected as our subjects.The final subjects was 42 cases due to 8 lost cases.The patients were randomly divided into two groups,including 30 cases in renin angiotensin aldosterone system inhibitors(RASI) group and 12 cases in Ca2+ channel blocker(CCB) group.Epidata 3.1 software was applied to perform statistic analysis.Urinary 8-OHdG concentration was measured by enzyme-linked immunosorbent assay (ELISA).Blood pressure was measured in spring,summer,autumn and winter.Results Systolic blood pressure(SBP) in RASI group and CCB group at winter periods were (158±20) mmHg,(158 ± 20) mmHg,higher than that in summer periods ((145 ± 12) mmHg,(141 ± 9) mmHg;P＜ 0.05).Diastolic blood pressure(DPB) in RASI group and CCB group at winter periods were (101 ± 13)mmHg and (100±4)mmHg,significant high than that in summer periods ((93 ±7) mmHg,(90±7) mmHg;P＜0.05).8-OhdG levels in RASI group at summer and autumn periods were (243.20±30.94) ng/L and (240.40±47.99) ng/L,significantly higher than that in winter and spring periods((190.80± 15.56) ng/L and (189.06± 13.56) ng/L),and the differences were significant(P＜0.001).No significant differences were seen in CCB group among 4 seasons in terms of 8-OhdG levels (P ＞ 0.05).Conclusion Blood pressure change still occur among 4 seasons in hypertensive patients after a single CCB containing RASI-based drug antihypertensive therapy.And blood pressure in winter periods is higher than that in summer,which indicates that therapy medication based on RASI might reduce the level of oxidative stress at winter periods.
