The abnormal gait after stroke was mainly related to the decreasing strength with increasing tension of paretic lower limb muscles. Surface electromyography (sEMG) can respond to the neuromuscular function, that is valuable for abnormal gait analysis for stroke patients. This paper mainly introduced the anatomical basis with sEMG features of walking, the performance of abnormal gait and ab-normal gait analysis based on sEMG. It focused on the advances of sEMG in the analysis of temporal patterns and activating characteristics of muscles associated with abnormal gait, as well as abnormal gait pattern.

Surface electromyography (sEMG), as an objective and quantitive assessment tool, has been used to evaluate the hand neural- muscle dysfunction after stroke in recent years. This paper reviews related literatures in nearly 10 years, which mainly introduced the common parameters of sEMG for the hand neural-muscle function, focused on the application of sEMG to estimate hand neural-muscle dysfunction after stroke.

Objective:To analyze infection-related factors for Coronary artery bypass grafting(CABG).Method: The cases undergoing operations with CABG from January to June in 2006 were 614.The records of the two sets of statistical indicators were kept and the data were analyzed to find the infection-related factors.Result:There were three factors related to infection:the measure of anaesthesia,the time of hospitalization before surgical operations and the duration of prophylac- tic antibiotics treatment.Diabetes mellitus was not a risk factor in our study.Conclusion:In view of patients'health condi- tion,prophylactic antibiotics can be used to prevent infection in surgical operations.Shortening the time of hospitalization before surgical operations and adopting off-pump coronary artery bypass grafting can decrease the infection.CABG is as safe for diabetic patients as for non-diabetic patients.

Objective To establish a RP-HPLC method for the determination of drug release in vitro of atractylenolide Ⅰ liposomes. Methods The release behavior of the drug from liposomes was studied by the third method for dissolution. ZORBAX C18 column (4.6 mm × 250 mm, 5 μm) was used with a mobile phase of Methanol-Acetonitrile-0.2% from liposomes in vitro fitted the log-normal distribution equation and had a property of sustained release. Conclusion The method is simple, fast and selective. It is suitable for the determination of release profile in vitro of atractylenolide Ⅰ liposomes.

Objective:To discuss the regularity of adverse drug reactions induced by statin.Method:82 cases from published articles were retrieved from 1998 to 2008.According to the given standard,the data were statistically analyzed. Result:77 articles carried 82 case reports concerning statins inducing ADRs in the period of 10 years.52 cases were caused by simvastatin.ADRs of statins could involve multiple organs and systems,mainly myopathys.Severe reaction could result in renal failure and even death.Conclusion:A rational use of statins should be strengthened in the clinical practice and strict monitoring in order to prevent and reduce the occurrence of serious adverse drug reactions.

Objective To summarize the clinical application of parenteral nutrition (PN) in Fuwai Hospital. Methods The clinical applications of PN in 132 critically ill patients undergoing cardiac surgery in our hospital were retrospectively investigated and analyzed. Results The application of PN in Fuwai hospital was basically appropriate and standardized. Energy supply in PN formulation was reasonably low, but still met the energy needs of patients in the fasting period. The nutritional composition and energy/nitrogen ratio in the formulation were basically rational. However, problems including the lack of double energy in partial formulation, low proportion of glucose-supplied energy due to low glucose-lipid ratio, and insufficient supply of insulin still existed. One (0.76%)patient was discharged according to his own decision; 22 ( 16.67% ) patients died, which were not directly associated with PN; and the other 109 (82.58%) patients were cured and discharged. Conclusion Application of PN for critically ill patients undergoing cardiac surgery must strictly follow the operation indications and rationally select nutritional components and proportions to ensure its safety and effectiveness.

Objective:To verify the association between social determinants and the quality of life ( QoL) among the elderly in Beijing .Methods:A questionnaire household survey was conducted and 1 685 over 60 dwellers in Beijing were interviewed .The EQ-5D scale was used to measure the elderly ’ s QoL and Time Trade-off model was used to calculate the EQ-5D index.Multiple linear regression and Logistic regression were employed to analyze the association between social determinants and the QoL .Results:There was no statistical significant difference in the QoL between the urban and the rural residents ( P>0 .05 ) .The elderly with higher education level and income or married tended to have higher overall QoL scoresand better performance of five dimensions of the QoL (P<0.05).Conclusion:More policies should be focused on the elderly with lower social determinants in both urban and rural areas in Beijing .

Objective To summarize our experience in management of infected femoral artery pseudoaneurysm caused by addictive drugs injection.Methods Clinical data of 45 cases of infeted femoral artery pseudoaneursysm were reviewed retrospectively.When infected femoral artery pseudoaneurysm was diagnosed,the femoral artery or external iliac artery was ligated and the pseudoaneurysm was resected in all of cases.Anticoagulants and antibiotics were used after operation.Results Lower limbs were salvaged in 44 patients.The ambulation function of affected limb was fine in the short-term.One limb was amputated because of lower limb deep venous thrombosis and gangrene.Thirty-four patients(75.6%) were followed up for 3-12 months,the results were satisfactory.Conclusions Femoral artery or external iliac artery ligation is an effective procedure for management of infected femoral artery pseudoaneurysm.
