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 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.

Purpose: To observe the regulative effect of acupoint application of abnormai lipid metabolism in type Ⅱ diabetes. Methods: Thirty patients with type Ⅱ diabetes were treated by acupoint application and routine hypoglycemic agents. Meanwhile, another 30 patients with type Ⅱ diabetes were treated by routine hypoglycemic agents only. A difference in the blood-lipid level between pretreatment and post-treatment was observed in the two groups. Results: Differences in cholesterol,triglyceride, low-density lipoprotein and high-density lipoprotein between pre-treatment and posttreatment in treatment group were significantly different from those in control group(P＜0.01).Conclusion: Acupoint application has a good lowering effect on high blood lipid and can effectively alleviate the disorder of lipid metabolism in diabetics.

Objective To study the cardiomyocyte and renal cell apoptosis induced by overtraining, and the preventive effects of anisodamine against the adverse effects. Methods The rats were forced to swim till exhaustion to reproduce the animal model of overtraining. The animals were randomly divided into control group, exhausted group and anisodamine group. The exhausted group, depending on the recovery time after exhaustion, was divided again into exhaustion subgroup, 6h after exhaustion subgroup, and 24h after exhaustion subgroup. The animals in the anisodamine group received intraperitoneally 10mg/kg of anisodamine before the swimming overtraining, and divided again into 6h after anisodamine injection subgroup and 24h anisodamine injection subgroup. The cardiomyocyte and renal cell apoptosis was observed by the method of TUNEL, image analysis and flow cytometry. Results It was revealed by TUNEL that the number of apoptotic cardiomyocytes was increased after exhaustive swimming, especially in the 6h after exhaustion subgroup. The number of apoptotic cells was also increased in kidney of 0h, 6h and 24h after exhaustion subgroups, especially in 24h after exhaustion subgroup. The apoptosis ratio was also increased significantly in 0h, 6h and 24h after exhaustion subgroups as demonstrated by flow cytometry. Compared with the rats of exhausted group, the number of apoptotic cells in heart and renal tissue was decreased remarkably after anisodamine injection. Conclusion The apoptosis of cardiomyocyte and renal cell could be induced by exhaustive swimming. Compared with kidney, heart injury recovered more quickly. Anisodamine had the preventive effect on the injury to heart and kidney in exhausted rats.

Objective To evaluate the value of the use of fibrin glue in radical mastectorny for breast cancer. Method 52 patients with breast cancer were divided randomly into two groups. In one group (27 patients) fibrin glue was used during radical mastectomy, while in the other group (25 patients), fibrin glue was not used. The volume of drainage on the first postoperative day and total volume of drainage after the operation were collected and measured. The fluid accumulation underneath the flap was also observed. Result In patients with the use of fibrin glue, the amount of drainage was much less compared with those without the use of fibrin glue. Having marked diversity ( P

Based on collecting data at home and abroad, we combined clinical practice of scientific researches. We also summarized key points for design and evaluation of clinical studies in treating children's attention deficit hyperactivity disorder by Chinese medical new drugs from objective and design, selection of diagnostic criteria, recruitment and dropping-out of subjects, effectiveness evaluation, safety evaluation, drug combination, and quality control, and so on. We hope to provide reference for design and evaluation of clinical studies by Chinese medical new drugs.
