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 compare the clinical outcomes of rheumatoid arthritis (RA) patients treated with different disease modifying antirheumatic drugs (DMARD) by analysing the clinical data and improve the understanding of different DMARDs.Methods The clinical data of RA patients who were treated and followed-up during Jan.1999 to Mar.2003 in Peking Union Medical College Hospital were retrospectively reviewed.The clinical efficacy and radiotogical changes were compared between patients treated with one DMARD only,2 DMARDs combination and 3 DMARDs combination.The short-term and long-term effects among different dosage regimens in the three groups,and the long-term results of different duration of DMARD treatment were also compared.Resuits Three hundred and twenty-night patients had their clinical and follow-up data available for analysis.Among them,256 patients had DMARDs as their initial treatment.Some of the patients showed eorticosteroid in their treatment regimen while some patients did not have steroid.The clinical effectiveness had no significant difference between patients who had corticosteroid or not.Patients treated with 2 or more DMARDs combination had more improvement in ESR,CRP level,morning stiffness and number of swollen and tender joints compared with one DMARD alone.There was no significant difference in adverse reactions between the 3 groups treated with DMARDs.Conclusion DMARDs combination treatment can significantly and rapidly improve the symptoms and lab parameters in RA.

Objective To investigate the correlation between tetramine poisoning and hypocalcemia in children.Methods According to different severe cases grade,tetramine poisoning children were divided into critical group(70-90 score),extremely critical group(

Objective To investigate the systemic stress responses after laparoscopic resection in colorectal cancer patients.Methods Sixty patients were randomized into the laparoscopic resection group (30 cases) and open resection group (30 cases) from October 2001 to September 2002 in our hospital.Analgesic dosages, recovery time of intestinal peristalsis, postoperative temperatures, C reactive protein(CRP), IL 6 and white blood cell (WBC) counts were recorded after operation. Results The changes of postoperative temperatures and WBC counts showed no significant difference between two groups.But in the laparoscopic resection group, the recovery time of intestinal peristalsis, postoperative analgesic dosages, CRP and IL 6 significantly decreased ( P

Objective To investigate and dispose an outbreak of seasonal influenza in hospital,so as to provide reference for the prevention and control of influenza outbreak in hospital.Methods Eight cases of influenza-like in-fection occurred in the department of neurosurgery at a hospital between July 29 and August 7,2014,epidemiologi-cal investigation was conducted,throat swabs of infected persons were collected for laboratory detection.Results Of 8 infected persons,6 were health care workers (HCWs)in department of neurosurgery,1 was a family member of HCW,and 1 was a patient,the major symptoms of the infected persons were low-grade fever,sore throat,and ma-laise,there were 67 patients and HCWs in this department,the attack rate of influenza was 11.94%,there was no similar infection in other departments of the hospital during the same period.The throat swabs from 6 infected HCWs were positive in influenza virus nucleic acid detection.Office for healthcare-associated infection (HAI)man-agement participated the investigation,after active isolation and antiviral treatment,the outbreak was effectively controlled.Conclusion This HAI outbreak is a seasonal influenza H3 outbreak,ventilation and environmental dis-infection in wards should be strengthened when central air conditioning is running,anti-influenza vaccination among HCWs should be performed during the epidemic season of influenza,and surveillance should be strengthened to pre-vent influenza outbreak in hospital.

Objective To investigate the correlation between uric acid level and increase of carotid intima-media thickness (IMT) in the elderly.Methods Clinical data of elderly and middleaged people who took health physical examination from Jan.2013 to Dec.2014 in a 3A-level hospital in Beijing were collected.The elderly people were divided into IMT normal group and plaque group.Logistic regression and linear regression were used to analyze the related factors for IMT thickening and uric acid level.Results The occurrence rate of hyperuricemia had a significant difference between the elderly group and the middle-aged group (P＜0.01).There were significant differences in uric acid level [(350.6±89.6) μmol/L vs.(359.6±86.6) μmol/L, t=5.19, P＜0.05].Body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), blood urea,cholesterol, high density lipoprotein levels between the IMT normal group and plaque group were [(25.3±3.6)kg/m2 vs.(25.8±3.5) kg/m2, (115.9±13.8) mmHg vs.(126.8±16.9) mmHg, (74.6±11.3) mmHg vs.(77.8±12.1) mmHg, (4.9±0.9) mmol/L vs.(5.0±1.0) mmol/L,(1.2±0.3) mmol/L vs.(1.2±0.3) mmol/L, all P＜0.01].Multi factor correlation analysis showed that the IMT thickening was correlated with gender, SBP, low density lipoprotein, blood glucose,while had no correlation with uric acid level.Blood uric acid level was related with gender, smoking, BMI, triglycerides, blood glucose, C-reactive protein, high-density lipoprotein.Conclusions Blood uric acid level, BMI, blood pressure and lipids are increased in the plaque group as compared with the IMT normal group.However, blood uric acid level can not be used as an independent risk factor for IMT lesions.
