Objective Investigating the expression of TLR3 and TLR7 mRNA in peripheral blood mononuclear cells (PBMC) of patients with chronic hepatitis C infection (CHC),to explore the effects of gender and age on Toll-like receptor expres-sion.Methods Peripheral blood was collected from 1 1 5 patients of chronic hepatitis C infection,1 1 3 healthy individuals.Ex-pression levels of TLR3 and TLR7 mRNA were detected by real-time quantitative PCR.Results The expression of TLR3 and TLR7 mRNA were significant difference between patients with CHC infection and healthy individuals (t=38.73,6.16, P<0.05),respectively.The expression of TLR3 and TLR7 mRNA were significant difference between premenopausal fe-males with CHC infection,postmenopausal females and young males of CHC infection (t=61.210,6.464,P<0.05;t=24.166,26.266,P<0.05),respectively.The expression of TLR3 and TLR7 mRNA were significant differences between old males and young males of chronic hepatitis CHC infection (t=86.349,19.583,P<0.05).The expression of TLR3 mRNA was significant differences between old males and postmenopausal females of CHC infection (t=122.941,P<0.05).There was no correlation between the expressions of TLR3 and TLR7 and HCV-RNA load of CHC patents of Gender and age dis-crepancies (|r|<0.40,P>0.05).The HCV-RNA load of premenopausal females was significant lower than young males and old females (t=3.49,2.51,P<0.05),the load of old males was lower than old females (t=2.35,P<0.05),however, there was no significant differences between old males and old females (t=1.20,P<0.05).Conclusion Gender and age dis-crepancies have a relationship with the expression of Toll-like receptors of patients with CHC infection,which may provide a theoretical basis and a new method for CHC.

Hepatitis C virus (HCV)was easily developed into hepatitis,cirrhosis and liver cancer after infecting human.Cur-rently,the traditional method of treatment of HCV was pegylated interferon and ribavirin program,which was ineffective and had poor side effects,while the new direct antiviral drugs were expensive.Therefore,looking for cheap and non-toxic side effects of treatment was the focus of current research.More and more evidence indicate that micro-Ribose Nucleic Acid (miRNAs)play an important role in the development of liver disease,regeneration and functional regulation.This review studies the relationship between miR-122 and Hepatitis C virus and hepatocellular carcinoma.

Objective: To examine the emotional states of asthmatic children with different degrees of severity, as well as the effects of emotion on change of cytokines in airway. Methods: Asthmatic children were divided into two groups according to the degrees of severity: moderate and mild. Their emotional states were measured and results were compared. Correlation analysis was conducted between scores on emotional scales and sputum levels of IL-8.Results: Total scores on anxiety and depression were higher in the moderate group than in the mild group. Negative correlation was found between levels of anxiety and IL-8 during acute exacerbation of asthmatic condition. Conclusion: Emotional distress was found to be increased with severity of asthmatic condition in children. Anxiety contributed to the decreased concentration of IL-8 in asthmatic children's airway.

Objective To evaluate the efficacy of preoperative biliary drainage (PBD) in the pancreaticoduodenectomy for malignant obstructive jaundice.Methods Database including PubMed,EMBASE,Cochrane Central Register of Controlled Trials,Academic Degree Dissertation Database and Conference Database were searched with malignant obstructive jaundice,pancreaticoduodenectomy,preoperative biliary drainage,comparative study.Literatures about the randomized controlled trials of PBD (PBD group) and efficacy of early surgery (ES group) in the pancreaticoduodenectomy were retrieved from January 2001 to December 2013,and then a Meta analysis was carried out based on the data.The count data were analyzed using the odds ratio (OR),relative risk (RR) and 95％ confidence interval (95％ CI),and the measurement data were analyzed using mean difference (MD) and 95％ CI.The heterogeneity of the data was analyzed using the I2 test.Data were integrated by fixed or random effect model.Results Twelve literatures including 1 982 patients were selected.There were 1 029 patients in the PBD group and 953 in the ES group.The results of Meta analysis showed that the operation time,volume of blood loss and rate of postoperative wound infection in the PBD group were significantly different from those in the ES group (MD =10.50,107.92,95％ CI:6.34-14.66,16.43-199.42;RR =1.62,95％CI:1.19-2.21,P ＜0.05).There were no significant differences in the postoperative mortality,incidence of pancreatic fistula,incidence of bile leakage,incidence of delayed gastric emptying and duration of hospital stay between the 2 groups (RR=0.69,95％CI:0.52-0.92;OR =0.68,1.35,95％CI:0.38-1.21,0.93-1.95;MD =0.69,95％CI:-0.67-2.05;RR =0.00,95％ CI:-0.02-0.01,P ＞0.05).Conclusion PBD in the pancreaticoduodenectomy for malignant obstructive jaundice cannot reduce postoperative mortality and incidence of complications in patients,and should not be used as the conventional management in the perioperative period.

Background It is thought in recently that photodynamic therapy (PDT) is an effective treatment method for chronic central serous chorioretinopathy (CSC), but the dosage of verteporfin and its long-term efficacy and complications is rarely elucidated ever before.Objective This study was to observe the long-term efficacy and safety of 60％ dose verteporfin PDT for chronic CSC.Methods This is a retrospective study and a self-controlled design was used.The clinical data of 25 eyes of 21 chronic CSC patients who received 60％-dose verteporfin PDT in Henan Eye Institute from January 2009 to May 2010 were reviewed, with the male 18 (85.71％) and female 3 (14.29％) as well as monocular CSC 17 patients and binocular CSC 4 patients.The average ages of the patients were (43±5) years.Fundus fluorescein angiography (FFA) , indocyanine green angiography (ICGA), optical coherence tomography(OCT) and best corrected visual acuity (BCVA) were examined in all the patients before and after treatment.PDT with the 60％-dose verteporfin (3.6 mg/m2) was carried out on the CSC eyes.The treated eyes were examined 2 weeks, 1 month and 3 months after PDT.The BCVA,subfoveal choroid thickness,FFA and ICGA findings before and after PDT were compared.The following-up duration was 5 years or more.Results The BCVA before and 3 months after PDT were 0.5 ±0.1 and 0.9±0.2, respectively, with a statistically significant difference between them (t =19.17,P =0.00).The subfoveal choroidal thickness value 3 months after PDT was (326.56±39.47) μm,which was significantly reduced in comparison with (486.24 ±47.53) μm before PDT (t =25.17, P =0.00).FFA and ICGA showed that the leakage of fluorescein (hyperfluorescence) was disappeared in all the treated eyes.No systemic or local adverse effects and recurrence were observed during the follow-up period.Conclusions On the basis of the results of this study and available information,60％-dose verteporfin PDT seems to have a better long-term efficacy and safety than full-dose verteporfin in treating chronic CSC.

The spike gene of porcine epidemic diarrhea virus (PEDV) was sequenced from 55 South China field strains isolated from pigs with symptoms of diarrhea. The sequences were compared within the set of field strains as well as with reference strains available in GenBank. Within the 55 South China PEDV field strains, the deduced amino acid sequence identities ranged from 93.8% to 99.9 % and ranged from 90.7% to 99.5% when compared with the foreign reference strains in GenBank. Our phylogenetic analysis showed that 10 of the 55 South China PEDV strains belonged to G1b and 45 belonged to G2b.
