Objective To observe the specific cellular immune response induced by co-immunization of DNA vaccine of Mtb8.4 and plasmid encoding human interleukin 12(hIL-12)in mice.Methods Fifteen C57BL/6N mice were divided into following groups:Mtb8.4 gene vaccine plus plasmid of hIL-12,Mtb8.4 gene vaccine,BCG,empty vector alone and PBS.Mice were immunized intramuscularly in both hind limbs three times at the intervals of three weeks or once subcutaneously with 1?106 of viable M.bovis BCG Pasteur at the time of the first DNA immunization.The level of IFN-? in supernatant of spleno-lymphocyte cultures was measured by ELISA.CTL activities of spleno-lymphocyte were detected with LDH release assay.Results The levels of IFN-? and IL-2 in supernatant of spleno-lymphocyte cultures in the group of Mtb8.4 gene vaccine plus plasmid of hIL-12 were significantly higher than that of group of Mtb8.4 alone(P

Objective To analyze the characteristics of rhabdomyolysis (RM) caused by alcohol withdrawal syndrome (AWS). Methods The clinical data of 7 patients with RM induced by AWS were analyzed retrospectively. Results All 7 patients were male;the age was 38-63 (51.3 ± 9.8) years. All of the 7 patients showed obvious myalgia and fatigue, of whom 4 patients had limb swelling, and 3 patients had epigastric pain. Creatine kinase and myoglobin levels of 7 cases were significantly increased. One case had acute renal failure. Seven patients were improved after treatment with a large amount of fluid infusion. Conclusions For patients with AWS who have generalized withdrawal seizures and epileptic seizures, muscle cells can be damaged due to prolonged muscle contraction, which can cause RM. Changes of myoglobin, creatine kinase, renal function and liver function in patients with AWS should be monitored at clinical admissions. If RM occurs, the patients should be given early fluid therapy.

Objective To systematically review the efficacy and safety of Jinlian Qingre Effervescent Tablet (JQET) compared to Ribavirin for acute upper respiratory tract infection in children.Methods CNKJ,CBM,WanFang Data,VIP,PubMed,EM base,Web of science,and Cochrane Library databases were searched from the date of establishment to December 2016 for all randomized controlled trials (RCTs) and quasi-RCT on the use of JQET in children with acute respiratory infections.Meta-analysis by using Rev Man 5.3.Results A total of seven RCTs involving 782 patients were included,while the group of JQET involving 392 patients,Ribavirin involving 390 patients.The results ofmeta-analysis indicated that the efficacy in Jinlianqingre group was superior to that of Ribavirin control group,such as clinical effectiveness [RR=l.26,95％CI=(1.18,1.34),P＜0.000 01],fever subsidence time [MD=-1.54,95％CI (-1.79,-1.30),P＜0.000 01],the time of subsided cough [MD=-1.53,95％CI (-1.79,-1.27),P＜0.000 01],the disappearance time of pharyngalgia [MD=-1.29,95％CI (-1.88,-0.70),P＜0.000 1],and Pharyngeal congestion disappearance time [MD=-2.80,95％CI(-3.11,-2.49),P＜0.000 01].The difference was statistically significant.There were three adverse reactions reported in JQET group.Conclusion JQET is superior to the Ribavirin control group in clinical effectiveness,fever subsidence time,time of subsided cough,disappearance time of pharyngalgia,and pharyngeal congestion disappearance time to treat acute upper respiratory tract infection in children.However,these results should be carefully interpreted,and this conclusion has to be further verified by high quality,large scale RCTs.

[Objective]The oxidative injury of retinal pigment epithelium(RPE)plays a key role in the pathogenesis of age-related macular degeneration(ARMD). This study is to investigate the effects of endoplasmic reticulum stress and the vital transcriptional factor X-box binding protein 1(XBP1)in acrolein-induced oxidative damage of RPE.[Methods]RPE cells were treated with acrolein (75μmol/L)for 2~24 h,expression of glucose regulated protein 78(GRP78)and XBP1 was determined by Western blot analysis. After being transfected with XBP1 siRNA with 24 h,the expression of XBP1 was knocked-down in RPE cells. Protein level of Nrf2 and SOD2 was then determined by Western blot analysis and intracellular Reactive Oxygen Species(ROS)generation was determined by DCF staining. Acrolein was added for 8 h after being transfected with XBP1 siRNA or control siRNA for 24 h. Apoptosis was detected by TUNEL assay before and after the treatment. Subretinal injection of Cre or GFP adenovirus was performed in XBP 1flox mice. After 1 week the mice were sacrificed. Total RNA was extracted from mice eyecups using TRIzol and real-time RT-PCR was performed to determine the two XBP1 down-stream genes,ERdj4 and p58IPK. Cryosectioning and immunofluorescent staining were performed to look at the expression of XBP1,Nrf2 and SOD2 in mice RPE.[Results]Protein level of GRP78 was significantly un-regulated after exposure to acrolein for 2 and 4 h. XBP1 was activated after acrolein treatment for 6 h. Knock-down of XBP1 by siRNA down-regu?lates anti-oxidant genes expression and increased ROS generation in RPE cells. Loss of XBP1 exacerbates acrolein-induced cell apoptosis. XBP1 was knocked-down in the RPE of XBP1flox mice after subretinal injection of Cre adenovirus. Decreased mRNA level of ERdj4 and p58IPK,and decreased Nrf2 and SOD2 expression were seen in the Cre-injected group.[Conclusions]Acrolein induces ER stress and activates XBP1 in RPE cells. Knock-down of XBP1 down-regulates anti-oxidant genes expression ,increases ROS generation,and exacerbates acrolein-induced cell apoptosis. XBP1 plays a role in the anti-oxidant defense in the RPE cells.

Objective:To investigate the anxious and despondent emotion in patients suffering from chronic eczema,and its influence factor thereof.Methods:The patients suffering from chronic eczema were investigated with self-rating anxiety scale(SAS),self-rating depression scale(SDS)and evsenck personality questionnaire(EPQ).The healthy persons were investigated with SAS and SDS.The severity of pruritus and skin rash in patients suffering from chronic eczema was assessed by visual analogue scale (VAS)and eczema area severity index (EASI).Results:The scores of SAS and SDS were significantly higher in patients with chronic eczema than that of healthy persons(P＜0.01).The multivariate stepwise regression analysis result demonstrated that the factors influencing anxious emotion were in turn severity of pruritus,disease position and stability of emotion introverted-extroverted disposition.The factors influencing despondent emotion were in turn disease position,course of disease,concealing,stability of emotion and severity of pruritus.Conclusion:There was obvious anxious and despondent emotion in patients with chronic eczema.These emotions were closely correlated with psychosocial factors,severity of pruritus and skin rash.

Objective To analyze the related immune parameters in liver transplantation recipients to help guide adjusting future immunosuppressants.Methods Fifty-three tolerant recipients after liver transplantation were included in this study.They had normal liver functions and took only one immunosuppressive drug.They were divided into the 3 ～5 years tolerance group (3Y group,n =21) (including 5 years) after transplantation,and the 5 ～ 11 years tolerance group (5Y group,n =32).Another 15 liver transplantation recipients who had twice or more recurrent acute rejections were enrolled as the RJ group and 32 age-matched healthy donors served as the HC group.The natural killer (NK) cells,B cells,memory T cells,regulatory T cells (Tregs) and the subsets were detected by flow cytometry.The plasma TGF-β level was evaluated using ELISA.Results The percentages of NK cells (3Y group 19.00 ± 0.09,5Y group 20.00 ±0.09,HC group 14.00 ±0.07,RJ group 9.00 ±0.03) and total Tregs within the CD4+ cells (3Y group 6.26 ±2.33,5Y group 4.80 ±2.21,HC group 3.04 ± 1.25,RJ group 1.09 ±0.81) in the 3Y,5Y and HC groups were significantly higher than those in the RJ group (P ＜ 0.05).The proportions of resting Tregs (3Y group 0.23 ±0.07,5Y group 0.16 ±0.02,HC group 0.07 ±0.02,RJ group 0.05 ±0.01),active Tregs (3Y group 0.56 ± 0.11,5Y group 0.42 ± 0.15,HC group 0.08 ± 0.02,RJ group 0.05 ± 0.01) and non-suppressive Tregs (3Y group 3.51 ±0.80,5Y group 3.71 ±0.41,HC group 1.44 ±0.14,RJ group 2.15 ± 0.62) increased significantly in the tolerant recipients after liver transplantation when compared with those in the HC and RJ groups (all P ＜ 0.05).No significant differences on B cells,memory T cells and TGF-β level were detected among in four groups.Conclusions The NK cells,total Tregs,resting Tregs,active Tregs and non-suppressive Tregs increased significantly in the tolerant recipients after liver transplantation.These might serve as potential biomarkers for immune tolerance.
