Abstract
Long-term use of levodopa in the treatment of Parkinson's disease can cause motor complications, which seriously impair the patients'motor function, reduce the quality of life, and aggravate the functional disability. Since there has been no effective treatment for motor complications, clarifying the influencing factors and prevention methods are conducive to reducing the risk of incidence and improving the quality of life of the patients. This paper summarizes the types and mechanism of motor complications of Parkinson's disease, the influencing factors ( levodopa dose, onset age, Helicobacter pylori infection and high protein diet ) and preventive measures ( psychological intervention, low protein diet, rehabilitation exercise and drugs ), so as to provide reference for the prevention and control of the disease.

The tail suspension test (TST), forced swimming test (FST) and chronic unpredictable mild stress (CUMS) model were used to evaluate the anti-depressant effect of supercritical CO2 extract from Compound Chaigui Fang (FFCGF). A nuclear magnetic resonance (NMR)-based metabonomics combined with multivariate statistical analysis was performed to explore the mechanism of FFCGF. Rats were conducted by CUMS procedure for 28 days and drugs were administrated at the same time. The body weight, sucrose preference, crossings and rearings in open-field tests were evaluated and the urine was collected simultaneously. The metabonomic profiles of rats' urine were analyzed by NMR and potential biomarkers were searched by multivariate statistical analysis. The results showed that administration of FFCGF significantly decreasing the immobility time in FST and TST and improving rats' body weight, sucrose preference, crossings and rearings in CUMS, which were indication that the anti-depressant effect of FFCGF was abvious. Significant differences in the metabolic profile of the CUMS treated group and the control group were observed, which were consistent with the results of behavioral tests. Decreased levels of acetic acid, succinic acid, 2-oxidation glutaric acid and citric acid and increased glycine and pyruvic acid in urine were significantly affected by the CUMS procedure and the 6 biomarkers were reversed evidently after administration of FFCGF. These changes were suggestion that the anti-depressant mechanism of FFCGF was associated with energy metabolism, lipid metabolism and amino acid metabolism.

T cell immune receptor with Ig and ITIM domains (TIGIT), a promising new target in cancer immunotherapy, plays a critical role in limiting adaptive and innate immunity against tumors. The extracellular domain of human TIGIT was used to immune BALB/c mice, and a new anti-human TIGIT chimeric antibody (c7D3) was developed. The mice in this study were used in accordance with the international guidelines for the care and use of laboratory animals, and the animal study was approved by the Institutional Animal Ethics Committee of AbMax Biotechnology. The biological activity of c7D3 was studied. The results showed that c7D3 exhibited high affinity for TIGIT and effectively inhibited the interaction between TIGIT and its ligands. Cell-based assays indicated that c7D3 induced strong luciferase signaling in TIGIT/CD155 signaling reporter assay and enhanced cytokine secretion in a T cell stimulation assay. The data showed that c7D3 has high binding affinity and excellent blocking bioactivity, supporting the further advancement for therapeutic application.

OBJECTIVETo investigate the etiology of 1977 patients from northern China with acute (ALF), sub-acute (SALF) or acute-on-chronic liver (ACLF) failures.
METHODThe age, gender, etiology, pathogenesis, and prognosis of the 1977 patients with liver failures were retrospectively analyzed.
RESULTSOf the 1977 cases, the three most common causes of ALF were HEV (33.96%) or HBV (13.21%) infections or those caused by medicines (9.43%). The three predominant causes of SALF were medicines (31.53%), HEV (16.22%) or HBV (9.91%) infections, but those of the ACLF were HBV (90.29%) infection, alcoholic hepatopathy (2.65%), and HBV super infected with HEV (2.26%) infections. 90.09% (1781) patients were infected by hepatotropic viruses. Of these 1781 patients, the most common cause of their liver failures was HBV infection (92.93%). In these HBV infected patients, 77.10% were from 26 to 55 years old. From 2005 to 2007, there were 39 patients with alcoholic liver failure. In the past two years, there were 23 patients with drug induced liver failure. The improvement rate of the 1977 patients after their treatments was 35.56%. The improvement rate of HEV infected liver failure was higher than drug induced liver failure (P less than 0.05); no statistical significance was found between other groups (P more than 0.05).
CONCLUSIONDifferent types of liver failure have different predominant causes. HBV infection is the most common cause in our 1977 patients. In the past two years, the number of drug induced liver failures and alcoholic liver failures have been increasing.

OBJECTIVETo understand the survival rate of adult blood-borne human immunodeficiency virus (HIV) cases in a county.
METHODSA retrospective cohort study was carried out to determine the survival from HIV infection and related factors among 78 adult HIV cases infected by blood and confirmed by the end of 2002. Kaplan-meier method was used to describe the survival distribution and Cox proportional hazard model was used to determine the factors associated with the survival time.
RESULTSThe total mortality after infection was 78.57/1000 p-y and AIDS related mortality was 72.95/1000 p-y. The median survival time was 7.40 years (95% Confidence Interval: 6.79 - 8.02). After adjustment for the clinical stage at presentation (HIV or AIDS), people who got infected at the age of 30 - 40 years or infected by the end of 1995 would proceed to death slower than the other groups.
CONCLUSIONThe survival of HIV cases infected by blood at the county level might have been underestimated and should be adjusted when HIV/AIDS was estimated and projected. Survival was associated with age when infection started so different survival functions should be used on different age groups that infection started.
