It is the objective foundation for carrying out such activities and affects the decision-making and the effect of activities.

Endoplasmic reticulum(ER) is a locus where proteins are modified,folded and calcium stored.The accumulation of unfolded protein and disorder of calcium ion can lead to ER stress.Early ER stress will induce unfolded protein response(UPR)which may be protective to cells.On the contrary,long-time strong ER stress will induce cell apoptosis,even death.ER stress has been suggested to be involved in some human neurodegenerative diseases.However,the exact contributions of ER stress in the various disease processes are yet unknown.This review mainly summarizes recently reported discoveries concerning ER stress associated with neurodegenerative diseases and highlights current knowledge in this field that may reveal novel insight into disease mechanisms and help to design better therapies for these disorders.

Aim To investigate the effect of α1-anti-trypsin Z variant (ATZ)overexpression on cell autoph-agy.Methods HEK 293T cells were transfected with pcDNA3.1 zeo+/ATM or pcDNA3.1 zeo+/ATZ,e-qual amount of empty vector was used as control.Cells were treated with NH4Cl for 4 hours and processed for detecting ATZ,LC3 and p62 by immunoblot.Mean-while ,expression and intracellular localization of ATZ, LC3 in 293 T cells were observed with double labeled immunofluorescence.The mRNA levels of autophagy-related genes were measured by real-time PCR.Immu-nohistochemistry was used to observe the morphology of ATZ-positive cells.Results Compared with the control,higher LC3Ⅱ levels and LC3 puncta were observed in ATZ transfected cells.Meanwhile,the levelsof p62 were decreased in ATZ transfected cells,andreversed by NH4 Cl (25 mmol·L -1 )treatment.Overexpression of ATZ increased the mRNA levels of Atg5and Atg12,but had no obvious influence on Beclin1.ATZoverexpressing cells presented abnormal morphologies.The nuclei became reduced,condensed,and even disappeared in ATZpositive cells.Conclusion ATZ overexpression increases autophagy activity whichmay be related to increasing Atg5 and Atg12 levels.

Objective To analyze the blood screening results after adjustment of critical value 40 to 50 U/L and to observe the effect of reducing blood scrap rate and to discuss the correlation between ALT and HBV,HCV infection.Methods We screened 2656 blood donors (ALT >40 U/L)by serological and nucleic acid amplification testing(NAT)in Qingdao blood center from 2013 to 2014,and conducted the correlation analysis by chi square test.Results 1 771 cases (66.68%)were ALT 40-50 U/L,including 6 cases of HBsAg ELISA (+),2 cases NAT (+),4 cases NAT(-).In the 8 cases of anti-HCV ELISA (+)samples,4 cases NAT (+),3 cases NAT (-),1 case with positive TP without NAT result.In 885 blood donors with ALT>50 U/L,5 cases were HBsAg-reactive,7 cases were anti-HCV-reactive,and 873 cases were negative.Related statistics showed that there was no signifi-cant difference between ALT and HBV infection (P <0.05),but significant difference was found between ALT and HCV infection (P >0.05).Conclusion The proportion of blood donors with ALT 40-50 U/L is much higher than that with ALT >50 U/L do-nors.Adjustment of the critical value greatly reduces blood scrap rate.Elevated ALT is associated with the infection of HBV but not with HCV.

Objective To investigate the change and clinical significance of serum procalcitonin (PCT) level in patients with community-acquired pneumonia (CAP).Methods One hundred and forty-five CAP patients were enrolled.Serum PCT level was measured by immunofluorescent antibody staining method.CURB-65 score and pneumonia severity index (PSI) score were used to evaluate the severity of the patients with CAP.Correlations between PCT and blood white blood cell (WBC) count,serum C-reactive protein (CRP),PSI score,CURB-65 score,hospitalization duration and mortality were analyzed with Pearson correlation analysis,Logistic regression analysis and so on.Results Serum PCT in patients with CAP showed positively correlated with CURB-65 score and PSI score (r =0.606,0.943,P＜ 0.01 ),and serum PCT was also positively correlated with age,serum CRP and hospitalization duration (r =0.753,0.233,0.281,P ＜0.01),but it wasn't correlated with blood WBC count (r =0.152,P ＞0.05).Logistic regression analysis showed that each increment of 1 μ g/L for serum PCT would increase 2.828-fold for the risk of death in CAP patients.Conclusions Serum PCT predicts the sensitivity and specificity of CAP with a similar prognostic accuracy with CURB-65 score and PSI score.Serum PCT in patients with CAP correlates with hospitalization duration and mortality.Therefore,it is a promising prognostic marker to evaluate the severity and outcome of CAP.It may serve as a useful marker for clinicians to evaluate the severity and prognosis of CAP.

BACKGROUND: As for the treatment of chylous fistula concurrent in oral-maxillofacial tumor resection simultaneously undergoing neck lymph node dissection, many different approaches have been put forward. A simple surgical ligation, strong negative pressure drainage, filling the muscle tissue alone or a combination of the above methods are all unsatisfactory regarding the prognosis and curative effect.OBJECTIVE: To evaluate the validity of medical biological adhesive cohering peripheral autologous muscle tissues to block thoracic duct fistula in order to prevent chylous fistula following neck lymph node dissection.METHODS: All of the 12 patients were detected and diagnosed as chylous fistula in neck lymph node dissection surgery, the wounds were immediately sutured and treated with medical biological adhesive cohering peripheral autologous muscle tissues to block thoracic duct fistula. RESULTS AND CONCLUTION: Of all the 12 patients, 10 recovered without chylous fistula or severe complications, and reoperations were adopted to cure the failed 2 cases. All patients were visited 3 months postoperatively, no recurrence of chylous fistula, local stimulus response or allergy was found. It is suggested medical adhesive to block thoracic duct fistula may be an effective and safe way for prevent chylous fistula following neck lymph node dissection.

Objective To analyze the feature of B cell epitope of soluble liver antigen(SLA) in autoimmune hepatitis. Methods Twenty-one autoimmune hepatitis(AIH) were enrolled the study. The control groups included 15 primary biliary cirrhosis(PBC) patients, 20 chronic virus hepatitis patients and 20 heaths. The serum incubated with coated one dimension of SLA peptide pools by ELISA for mapping the B cell epitopes. ELISPOT was performed to screen the SLA specific T cell response by observing the secretion of IFN-γ after PBMC simulated. Results Ten serum samples from AIH patients recognized the SLA peptide pools, the frequency was 47.62%, which was higher than PBC group, virus hepatitis group and normal control group, P value was 0.001, <0.001 and <0.001, respectively. The 10 positive serum dominant response to SLA 7 th pool(aa385-441), which laid in the unique no conservative region of the SLA molecular. T cell recognizing regions laid dominantly in first and second pool, the frequency was 30% and 40%, respectively, however the recognized frequency of 7th pool was 10%. Conclusion B cell linear epitopes lie in the sequence aa385-441, which is the unique unconservative region in the high conservative SLA molecular and overlaps with part sequence of T cell epitopes. The results show it is complex and interaction that SLA induced humoral-mediated immunity and cellular immunity to involve in AIH pathogenesis.
