Cellular autophagy is a major degradative pathway for clearance of aggregate-prone proteins and damaged organelles. It plays an important role in regulating cellular homeostasis, cell growth and development, and disease development. Dysfunctional autophagy contributes to the pathology of various neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and Huntington's disease, in which specific pathological protein accumulation occurs. A growing body of evidence suggests that resveratrol plays a significantly role in the regulation of autophagy and clearance of pathological proteins. Resveratrol is a potential drug for neurodegenerative diseases therapy. This review focuses on the effects of resveratrol on cellular autophagy and clinical application in the control of neurodegenerative diseases.

Objective To investigate the clinical value of serum endocan and procalcitonin (PCT) in early diagnosis and prognosis evaluation of sepsis.Methods The patients with systemic inflammatory response syndrome (SIRS,n = 26) and sepsis (n = 78) admitted to intensive care unit (ICU) of the Third Hospital of Hebei Medical University from December 2014 to December 2016 were enrolled. According to the severity of disease, the sepsis patients were divided into general sepsis group (n = 20), severe sepsis group (n = 24), and septic shock group (n = 34). The cases were divided into survival group (n = 55) and non-survival group (n = 23) according to 28-day mortality. The serum endocan, PCT, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, and sequential organ failure assessment (SOFA) score were recorded when the patients were admitted into ICU. The differences in endocan, PCT, APACHE Ⅱ, SOFA score between SIRS and sepsis groups and within sepsis subgroups were compared. Spearman correlation analysis was used to analyze the correlation between the indexes of sepsis patients. Receiver operation characteristic curve (ROC) was used to evaluate the value of endocan and PCT for the diagnosis and prognosis of sepsis.Results ① Serum endocan, PCT, APACHE Ⅱ, SOFA score and 28-day mortality in the sepsis group were significantly higher than those in the SIRS group [endocan (μg/L): 4.28 (10.64) vs. 1.03 (0.69), PCT (μg/L): 3.94 (10.75) vs. 0.43 (0.39), APACHE Ⅱ:18.81±9.17 vs. 9.35±3.78, SOFA: 9.00 (7.20) vs. 4.50 (1.50), 28-day mortality: 29.49% vs. 11.54%, allP < 0.01]. The area under the ROC curve (AUC) of endocan, PCT, APACHE Ⅱ, SOFA score for sepsis diagnosis were 0.887, 0.842, 0.822, 0.835, respectively. When the cut-off value of endocan was 1.26μg/L, the sepsis diagnostic sensitivity was 87.2% and specificity was 81.8%. When the cut-off value of PCT was 0.75μg/L, the sepsis diagnostic sensitivity was 85.9% and specificity was 81.8%. ② With the severity of the disease increased, the index showed an increasing trend in patients with sepsis. Serum endocan, PCT, APACHE Ⅱ, SOFA score and 28-day mortality in septic shock group were significantly higher than those in severe sepsis group or general sepsis group [endocan (μg/L): 13.02 (6.70) vs. 3.33 (3.05), 1.60 (0.98); PCT (μg/L): 8.10 (17.68) vs. 5.47 (8.92), 1.57 (2.78); APACHE Ⅱ: 25.00 (9.50) vs. 18.00 (9.00), 9.50 (5.75); SOFA: 13.00 (4.50) vs. 8.00 (3.00), 5.00 (3.50); 28-day mortality: 52.94% vs. 20.83%, 0%; allP < 0.01]. There was a significantly positive correlation between endocan, PCT, APACHE Ⅱ, SOFA, indicating that the endocan and PCT can be used to assess the severity of sepsis. ③ Serum endocan, PCT, APACHE Ⅱ and SOFA score in non-survival group were significantly higher than those in the survival group [endocan (μg/L): 15.05 (9.23) vs. 2.32 (4.81), PCT (μg/L):18.40 (16.99) vs. 3.10 (6.67), APACHE Ⅱ: 28.13±7.56 vs. 14.91±6.64, SOFA: 14.70±3.65 vs. 7.38±3.26, allP < 0.01]. The AUC of endocan, PCT, APACHE Ⅱ, SOFA score for the prediction of non-survival sepsis were 0.915, 0.763, 0.899, 0.930. When the cut-off value of endocan was 4.37μg/L, the septic death prediction sensitivity was 95.7% and specificity was 70.9%. When the cut-off value of PCT was 7.68μg/L, the septic death prediction sensitivity was 65.2% and specificity was 78.2%.Conclusions Serum endocan is more clinically valuable than PCT in early diagnosis and prognosis assessment of sepsis.

Translational medicine is a novel concept about combination of basic research and clinical application. The aim of translational medicine is to realize the translation of basic research into clinical practice. microRNAs (miRNAs) are non-coding single-stranded RNAs with 21-25 nucleotides in length as newly discovered factors in regulating gene expression. Recently, the key regulatory role of miRNA in the cardiovascular system has been elucidated and amount of remarkable results has been achieved, particularly in the regulation of cardiac arrhythmias. A series of studies demonstrate that miRNAs are involved in the regulation of expression of a variety of proteins associated with cardiac electrical activity, and are the potential targets of occurrence of cardiac arrhythmias and anti-arrhythmic drugs. miRNAs as a therapeutic target regulate the stability of mRNAs of target genes or play an inhibitory role in the translation process. Stability of the corresponding miRNA expression levels in the target organ may be a new approach for the disease therapy. Regarding the dysfunction of miRNA, we employed miRNA re-expression strategy and anti-miRNA strategy to correct target protein function and provide a new entry for the therapy of arrhythmia. With the technology of miRNA mimics and antagomirs, miRNAs are expected to treat various cardiovascular diseases and will provide a fresh impetus to achieve transform medicine.

Objective To compare the efficacy of different antibiotics strategy,introperitoneal (IP) cefazolin plus third-generation cephalosporin versus IP Vancomycin plus thirdgeneration cephalosporin on peritoneal dialysis (PD)-related peritonitis.Methods All episodes of PD -associated peritonitis happened in prevalent PD patients between January 2008 and December 2012 were recruited from the PD Center of Peking University First Hospital.According to their empiric antibiotics scheme,episodes were divided into group A (where IP cefazolin plus third-generation cephalosporins were administrated) and group B (where IP Vancomycin plus third-generation cephalosporins were administrated).Multivariable logistic regression model was used to explore the influence of different emnpiric antibiotics scheme on peritonitis outcome.Results Patients in Group B had significantly lower level of serum albumin (33.5±6.0 vs 35.3±5.2 g/L) and cholesterol (4.6±1.3 vs 4.9± 1.1 mmol/L) than those in group A.In group A,the percentage of gram-positive bacteria was similar to group B (43.2％ vs 43.3％,P =0.96),but gram-negative bacteria was numerically lower (16.9％ vs 24.7％,P =0.08).Different empiric antibiotics strategy was not independent predictor of peritonitis outcome [OR =1.07,95％ CI(0.45,2.56),P=0.87].Conclusion Both cefazolin and vancomycin can be selected as first-line empiric antibiotic covering gram-positive organisms in the treatment of PD related peritonitis.
