Toll-like receptor is a receptor to identify the pathogen associated molecular,which relates the natural immune with required immune.Toll-like receptor activates natural immune and induces several cytokines.As a result,it will influence the differentiation of initiated T-cell by identifying Pathogens.The main Tolllike including TLR2、3、4、7、8、9 are closely related with anti-rotavirus to identify the natural immune affection of rotavirus.This review to explain the pathogenesis of Toll-like in rotavirus infection,as well as the key role which Toll-like plays in preventing rotavirus infection and controlling the inflammation.

Vascular stenosis can mainly be divided into two types:the congenital vascular stenosis and acquired vascular stenosis.The etiology of congenital vascular stenosis is unclear yet,it usually occurred in different types of congenital cardiovascular and cerebrovascular stenosis.Acqnired vascular stenosis is often caused by athemsclerotic plaque,resulting in the percutaneous brace implantation,or balloon angioplasty.Imaging methods can be helpful in the clinical diagnosis and evaluation of various congenital or acquired vascular stenosis accurately and timely.Currently,imaging technology has developed rapidly and the new imaging technology emerges.This paper briefly reviews the imaging technology progress in evaluating the vascular stenosis.

Objective To investigate the effects of inhalation of isoflurane (Iso) on pulmonary and systemic inflammatory response through the changes in the plasma and pulmonary levels of IL-1β and IL-10 in rats. Methods Thirty-two adult male Wistar rats were randomly divided into 4 groups (n=8 each): group control (group C), group Iso-4 h, group Iso-8 h and group R. Group C inhaled air only. Group Iso-4 h and Iso-8 h inhaled in 40% O2 + 1.5% Iso for 4 and 8 h respectively. Group R inhaled 40% O2 + 1.5% Iso for 8 h and then withdrew and only inhaled 40 % O2 for 2 h. Blood samples were taken from femoral artery for measurement of plasma concentrations of IL-1β and IL-10 by ELISA. Then the rots were sacrificed to collect bronchoalveolar lavage fluid (BALF) for measurement of IL-1β and IL-10 concentrations. The right lung tissues were obtained for determination of the expression of IL-1β mRNA and IL-10 mRNA by RT-PCR. Results The BALF concentration of IL-1β and IL-1β mRNA expression in lung tissues were significantly higher in group Iso-4 h, and the concentrations of plasma and BALF IL-1β and IL-10, and the expression of IL-1β mRNA and IL-10 mRNA in lung tissues were significantly higher in group Iso-8 h than in group C (P<0.05), but there were no significant differences in the concentrations of plasma and BALF IL-1β and IL-10 and expression of IL-1β mRNA and IL-10 mRNA in lung tissues between group R and group C (P>0.05). The plasma and BALF IL-10 concentrations and IL-10 mRNA expression in lung tissues were significantly higher in group Iso-8 h than in group Iso-4 h (P<0.05). The concentrations of plasma and BALF IL-1β and IL-10 and expression of IL-1β mRNA and IL-10 mRNA in lung tissues were significantly lower in group R than in group Iso-8 h (P<0.05). Conclusion Isollurane inhalation can induce transient pulmonary and systemic inflammatory response in rats.

Objective To investigate the clinical effect of pegylated interferon(IFN)on chronic hepatitis C and its effect on cellular immune function.Methods A total of 92 patients with chronic hepatitis C were enrolled in our hospital from June 2013 to October 2016.They were randomly divided into study group and control group by single and double numbers(admission order),with 46 cases in each group.The control group was treated with recombinant human interferon alpha-2b on the basis of conventional treatment.The study group was treated with pegylated interferon alpha-2a on the basis of conventional treatment.Results After treatment, the rates of RVR, EVR, ETVR and SVR in the study group(52.17%, 71.74%, 76.09% and 54.35%, respectively)were significantly higher than those in the control group(34.78%, 50%, 58.70%, 39.13%, respectively), The difference was statistically significant(P<0.05).There were no significant difference in the cellular immune function index between the two groups before treatment;After treatment,the CD3+, CD4+, CD4+/CD8+ and other immune function indexes of the study group were significantly higher than those before treatment, while the results of CD8+ were significantly lower than before treatment(P<0.05);There was no significant difference in the cellular immune function in the control group compared with before, and the difference of the cellular immune function between the 2 groups after treatment was statistically significant(P<0.05).Conclusion Pegylated interferon(IFN)on the basis of routine treatment can improve the virologic response and cellular immune function in patients with chronic hepatitis C.

OBJECTIVE:To observe the protective effect of different extraction samples from Salvia miltiorrhiza decoction on acute myocardial ischemia model mice. METHODS:96 mice were randomized into blank control group (normal saline),model group(normal saline),positive drug group [Compound Salvia miltiorrhiza tablet,4.6 mg(crude drug)/(kg·d)],high-dose,medi-um-dose and low-dose groups of water extract,supercritical CO2 extract and supercritical CO2 extract+dregs water extract [24,12, 6 mg(crude drug)/(kg·d)],with 8 mice in each group,12 groups in total. They were given medicine intragastrically once a day. On sixth day,30 min after giving drugs,those groups were given isoprenaline 20 mg/kg,ih,to induce myocardial ischemia model except for blank control group,once a day,for consecutive 3 d. Electrocardiogram ST segment variation of mice were observed. The times and duration of buccal respiration were observed after rapid decapitation,and the activities of CK and LDH in serum were determined. RESULTS:Compared with blank control group,electrocardiogram ST segment and the activity of CK and LDH increased in model group,while the times and duration of buccal respiration after rapid decapitation reduced(P<0.01);compared with model group,above indicators of medication groups had been improved (P<0.01),and were positively correlated to drug concentration;the indicators of supercritical CO2 extract+dregs water extract group were most close to those of blank control group. CONCLUSIONS:Different extraction samples from Saliva miltiorrhiza decoction all have protective effect on acute myocardial ischemia model mice,and the protective effect of supercritical CO2 extracting+dregs water extracting sample of Salvia Miltiorrhiza decoction is best.
