Autophagy is a physiological process which delivers the mutant cytoplasmic proteins and dysfunctional subcellular organs into lysosomes for degradation to generate fuel in the deficiency conditions. It is mainly classified into macroautophagy, microautophagy and chaperon-mediated autophagy (CMA), as well as the selective autophagy such as mitophagy and aggrephagy. This review mainly introduces the key molecular markers of macroautophagy, CMA and mitophagy.

Objective To investiGate the distribution of clinical infectious pathoGens and druG resistance status of common bacteria in the Ninth Peopleˊs Hospital Affiliated to medicine School of ShanGhai Jiao TonG University in 20l2. Methods Clinical isolated bacterial strains were collected from the Ninth Peopleˊs Hospital Affiliated to medicine School of ShanGhai Jiao TonG University durinG 20l2. The identification of bacteria and antimicrobial susceptibility were determined by VITEK 2 COMPACT automatic microbioloGy analyzer. The data were analyzed by WHONET 5. 4 software. Results A total of 3456 pathoGenic strains were collected. Of them,Gram positive cocci,Gram neGative bacilli and funGus accounted for 20. 3%,76. 8% and 2. 9% respectively. Methicillin resistant strains in S. aureus( MRSA ) and coaGulase neGative Staphylococcus ( MRCNS)accounted for averaGe of 44. 4% and 85. 5% respectively. No vancomycin and linezolid resistant strains were found. Extended spectrumβ-lactamases strains accounted for 66. 4% and 30. 6% in Escherichia coli ( E. coli)and Klebsiella spp respectively. Strains of E. coli and Klebsiella spp were still hiGhly susceptible to imipenem. Resistance rates of P. aeruGinosa and A. baumannii sppstrains to imipenem were 8. 3% and 58. 4%respectively. Conclusion The major clinical pathoGenic microorGanisms in the Ninth Peopleˊs Hospital Affiliated to medicine School of ShanGhai Jiao TonG University are still Gram neGative bacilli. Baterial resistance is serious. It is important to strenGthen the detection of resistant bacteria in routine work,which is useful for rational use of antimicrobial aGents.

Objective To conduct a Meta-analysis to evaluate the efficacy and safety of interfer on-α for treating HBeAg-positive chronic hepatitis B in children.Methods PubMed and Chinese Biomedical Database were searched from the beginning to April 2006,and the references of eligible studies were manually screened.Randomized controlled trials published in the English and Chinese literature comparing interferon-α with non-antiviral interventions(placebo or no treatment)in children with chronic hepatitis B were eligible for inclusion.Studies were included if patients were treated for at least 3 months and followed up for at least 6 months after cessation of therapy.Two investigators independently assessed the quality and extracted the data.The methodological quality of trails was assessed by the Jadad-scale plus allocation concealment.Heterogeneity was examined by Chi-square test.Fixed effects model or random effects model was used to pool the data.Sensitivity analyses were used in the treatment course.Results Seven randomized controlled studies with a total of 360 child chronic hepatitis B virus carriers who were positive for hepatitis B surface antigen and hepatitis B e antigen werc identified.It was found by Meta-analysis that,compared with the control,at the end of therapy,interferon-α could significantly clear HBeAg[22.1%vs 6.7%,OR 3.56,95% CI(1.74, 7.28),P=0.000 5],HBV DNA[33.7% vs 12.6%,OR 3.50,95% CI(2.03,6.06),P＜0.01], HBsAg [6.5% vs 0.5%,OR 7.10,95% CI(1.52,33.12),P=0.01],and achieve HBeAg seroconversion [17.3% vs 2.9%,OR 5.62,95% CI(1.65,19.18),P=0.006],but was not more effective in HBsAg seroversion[2.0% vs 0,OR 3.55,95%CI(0.35,35.93),P=0.28]and alanine aminotransferase(ALT)normalization[24.2% vs 16.2%,OR 1.72,95% CI(0.84,3.52), P=0.14].Conclusions Interferon a may be efficacious in clearance of HBeAg,HBV DNA and HhsAg, and achievement of HBeAg seroversion.Little evidence is available on HBsAg seroversion and ALT normali zation.Rigorously designed large sample size randomized double blind clinical trials with large sample size are required to further confirm and support the conclusion.

Objective To investigate the association between morniing blood pressure surge (MBPS) and carotid atherosclerosis in elder patients with essential hypertension. Methods According to the results of24h ambulatory blood pressure monitoring, 106 patients were classified as the morning BP surge group (MBPS group,n = 58) ,and nonsurge group (NMBPS group, n = 48). Patients underwent carotid ultrasound and the intima-medial thickness (CCA-IMT) and plaques were examined. Results The CCA-IMT of the MBPS group was significantly thicker than that the NMBPS group[(1.27 ± 0. 12)mm vs (0.92 ± 0.33 )mm], P ＜ 0. 05 ) ;②Compared with the NMBPS group,the severity of carotid arteries plaque of the MBPS group was significantly higher (72. 15% vs 54.21% ), ( P ＜0. 01 ) ;③Pearson relation analysis showed CCA-IMT level positively correlated with age (r = 0.288, P ＜ 0.001 ) ,the average of 24h SBP ( r = 0. 768 ,P ＜ 0. 001 ), and MBPS ( r = 0. 768, P ＜ 0.001 ). Conclusion The study showed that MBPS was closely related with carotid atherosclerosis in elder patients with essential hypertension and was an important risk factor in the process of atheresclerosis.
