Objective To review the clinical features of drug-induced liver injury (DILI) in elderly Chinese patients.Methods A literature search was conducted with the key wordsdrug-induced liver injury ordrug-induced liver disease andelderly; four Chinese medical databases were used:including Chinese Biomedical Literature Database (CBM),Chinese Science and Technology Periodical Database (VIP),Wanfang Database and China National Knowledge Infrastructure (CNKI),from when the bases established to December 2011.Data from retrieved literatures of retrospective controlled studies of DILI were analyzed by SPSS 14.0 software.Results Five studies met the inclusion criteria,including 275 elderly patients (aged group) and 602 non-elderly patients (non-aged group) with DILL There was no significant difference in gender between the two groups (P ＞ 0.05).Clinical manifestations of jaundice,fatigue,anorexia,and skin itching were more commonly seen in the aged group (P ＜ 0.01).Cholestatic hepatic injury occurred more frequently in the aged group than in the non-aged group [24.9％ (61/245) vs.18.8％ (102/245),P ＜ 0.05],while hepatocellular type occurred more frequently in the non-aged group [64.3％ (350/544) vs.55.1％ (135/245),P ＜ 0.05].More DILI were induced by Chinese herb medicine and cardiovascular drugs in the aged group than in the non-aged group [47.0％ (79/168) vs.35.9％ (93/254) and 8.3％ (14/168) vs 1.2％ (3/259) respectively,P ＜ 0.05].As for the prognosis,there was no significant difference in clinical cure and improvement rate between the two groups [84.4％ (141/167) vs.81.5％ (291/357),P ＞0.05].Conclusion The elderly are more sensitive to the drugs and have a high risk of DILI.Prevention and timely diagnosis and treatment of DILI are particularly important for elderly patients.

Source data and its source documents are the foundation of clinical research. Proper source data management plays an essential role for compliance with regulatory and GCP requirements. Both paper and electronic source data co-exist in China. Due to the increasing use of electronic technology in pharmaceutical and health care industry, electronic data source becomes an upcoming trend with clear advantages. To face new opportunities and to ensure data integrity, quality and traceability from source data to regulatory submission, this document demonstrates important concepts, principles and best practices during managing source data. It includes but not limited to: (1) important concepts of source data (e.g., source data originator, source data elements, source data identifier for audit trail, etc.); (2) various modalities of source data collection in paper and electronic methods (e.g., paper CRF, EDC, Patient Report Outcomes/eCOA, etc.); (3) seven main principles recommended in the aspect of data collection, traceability, quality standards, access control, quality control, certified copy and security during source data management; (4) a life cycle from source data creation to obsolete is used as an example to illustrate consideration and implementation of source data management.

Neurodegenerative disease is characterized by progressive loss of neurons in specific brain regions that results in neuronal dysfunction of the central nervous system. Although the pathological mechanism is not fully established, the activation of glial cells mediated neuroinflammation appears to be involved. Heat shock protein 70 (HSP70) is originally described as intracellular chaperone, which plays an important role in protein quality control in cells. However, recent study showed that up-regulation of HSP70 had anti-inflammatory effects in the brain. HSP70 protected neurons from damage and improved neurological function by decreasing inflammatory response as indicated by inactivation of glial cells and inhibition of pro-inflammatory cytokine release. So it is of great significance to find new compounds targeting at HSP70 as neuroprotective agents to delay the progress of neurodegenerative disease. This review will focus on the role of HSP70 in neuroinflammation and the recent advances in using HSP70 as a target for the treatment of neurodegenerative disease.

The aim of this study is to investigate the protective effect of N-[2-(4-hydroxyphenyl)ethyl]-2-(2, 5-dimethoxyphenyl)-3-(3-methoxy-4-hydroxyphenyl)acrylamide (FLZ), a novel synthetic squamosamide cyclic derivative, against Parkinson's disease (PD) model mice induced by the inflammatory bacterial endotoxin, lipopolysaccharides (LPS) and the neurotoxin 1-methy-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP). C57/BL mice were ip injected LPS (5 mg x kg(-1)) once. One week following the LPS injection, mice received a subcutaneous injection of MPTP (25 mg x kg(-1)) once daily for 2 days. Eight weeks later, FLZ (25, 50 and 75 mg x kg(-1)) was orally administered to mice once daily for 60 days. The motor ability of the mice was evaluated by rod climbing test and footprint test. The dopamine (DA) levels in mouse striatum were determined by high performance liquid chromatography system. The tyrosine hydroxylase (TH)-positive cells were showed by immunohistochemical analysis. FLZ treatment significantly improved motor dysfunction of mice challenged by LPS plus MPTP. The increase of TH-positive cell numbers and elevation of DA levels may be contributed to the beneficial effects of FLZ on motor behavior. This study showed FLZ has significant therapeutic effect on LPS plus MPTP induced chronic PD model, which indicates its potential as a new candidate drug to treat PD.

The arrangement of fascicles of musculocutaneous nerve at different levels in brachial plexus were studied in 22 adult cadavers. The nerve fascicles were dissociated and traced under operative microscope. At the distal end of the musculocutaneous nerve, the muscular and cutaneous fascicles are separated.The muscular fascicles are situated at the latero-anterior quadrant of the cross-section of the nerve.The mixed fascicle are become predominated proximally. The muscular and the muscular predominated mixed fascicles are still situated at latero-anterior quadrant. At the level 1 cm below the clevicle, 1cm and 1.5 cm above the clevicle,the fascicles of the nerve are situated at the lateral superio-anterior quadrant of the crosssection of relative parts of brachial plexus. The fascicles of the nerve are situated at the anterior quadrant of the crosssection of superior trunks. The fibers of musculocutaneous nerve are originate from C5, C6 and C7, being 31.6,％, 64.6％ and 3.8％,respectively.
