hemiplegic patients following stroke were devided into two groups一一group A andgroup B for this study. Rehabilitation treatment started for the patients in group A in one month,yet forthose in group B in two or three months after onset of the stroke. Compared the conditions of the twogroups of patients before their rehabilitation treatment,there was no obvious difference(P<0.05)in thefour aspects of their motor ability(Ⅰ-activity in bed;Ⅱ-aclivity in wheel-chair;Ⅲ-in-ward;Ⅳ-outdoor activity).While the result of analysis on their post-treating shift of motor ability showed that thetrend,which the proportion of patients with ability Ⅰ andⅡ decreased but the proportion of patients withability Ⅲ and Ⅳ increased,was more significant in group A than in group B(P<0.05).Thereby it indicatesthat the early starting of rehabilitation treatment is favourable for improving motor ability of hemiplegic pa-tients following stroke.

Objective To investigate the protective effect of exogenous oxygen and superoxide dismutase (SOD) on acute spinal cord injury. Methods A rabbit model of L2 spinal cord injury was produced by Allen's method, and then the rabbits were randomly divided into experimental group and control group. In the experimental group, the rabbits received exogenous oxygen, SOD or both 30 min after injury. 12h after injury, the amount of MDA and SOD of spinal tissues were determined, and pathological changes of spinal cord were observed at the fourth weeks after injury. Results Combinant administration of exogenous oxygen and SOD could inhibit MDA production and increase SOD activities, effect of which was stronger that single administration (P

Objective To study the association between platelet distribution width (PDW) and other indexes in coronary heart disease (CHD) patients with heart failure (HF).Methods Five hundred and ninety-one CHD patients with HF were divided into control group with their NT-proBNP＜300 ng/L (n=228),mild HF group with their NT-proBNP=300-3000 ng/L (n=191),and severe HF group with their NT-proBNP＞3000 ng/L(n=172).Their blood and echocardiographic parameters were recorded.Results The PDW was significantly shorter in 3 groups after treatment than before treatment (0.129±0.031 vs 0.133±0.027,0.133±0.030 vs 0.141± 0.029,0.139±0.028 vs 0.148±0.029,P＜0.05,P＜0.01),and was significantly longer in mild HF group and severe HF group than in control group and in severe HF group than in mild HF group after tgreatment (P＜0.05,P＜0.01).Multivariate stepwise regression analysis showed that PDW was positively associated with NT-proBNP and LAD (P=0.001,P=0.000) and negatively associated with LVEF (P=0.003).Conclusion PDW increases with the severity of HF in CHD patients and can thus play an auxiliary role in assessing the severity of their HF.

Objective: To synthesize 10-position schiff base derivatives of emodin and study the anti-tumor activity. Methods:The 10-position schiff base derivatives of emodin were synthesized through emodin reacting with ammonia derivatives in absolute alcohol with acetic acid as the catalytic agent. Their structures were characterized by 1 H-NMR and ESI-MS, and the anti-tumor activity on k562 cells was determined by MTT method. Results:Three 10-position schiff base derivatives were synthesized and the structures were confirmed, and the IC50 on k562 cells was 4. 5, 3. 8 and 2. 0 μmol·L-1 , respectively. Conclusion:The 10-position schiff base de-rivatives of emodin can improve the anti-tumor activity and druggability of the parent compound, which are worthy of further study.

Objective To assess the clinical use of anti-Parkinson's disease(PD)drugs in the patients with PD,and provide a basis to formulate an effective clinical drug program.Methods 190 PD patients were interviewed by questionnaires about resources,dosage and costs of anti-PD drugs from April,2004 to March,2005.Results By retrospective analysis,number of drugs used in per patient per year was 2.88;levodopa dosage and Levodopa Equivalents(LDE)per patient were 323.0 mg/d and 318.6 mg/d respectively,and LDE increased significantly following by scores of Hoehn-Yahr(H&Y)class increasing(P

Objective To investigate the relationship between acupuncture analgesia and cellular immunity, the acupuncture effect on expression of c fos mRNA, ppENKmRNA,iNOSmRNA and iNOS activity in the mouse peritoneal macrophage were studied. Methods Twenty BALB/c mice were randomly divided into 2 groups:a,the acupuncture group treated with 5Hz electroacupuncture (EA); b, the control group treated with no EA. The pain threshold was detected by K + ionophoresis method before and after EA or restraining. The experiment was performed by using in situ hybridization, NADPH NBT histochemistry, RNA dot blot and protein dot blot techniques. All dot blot signals were scanned for statistical analysis. Results The hybridization signals and iNOS activity appeared as granules in bluish violet color, localized in the cytoplasm of the macrophage. All dot blot signals were increased in the acupuncture group, when compared with those in the control group( P

Objective To evaluate the role of arthroscopy in diagnosis and treatment of osteoarthritis of the knee.Methods The data of 108 patients (118 knees) with osteoarthritis of the knee and received arthroscopic surgery were analyzed retrospectively including sign, X-ray and MRI examinations of knee, the average stage in hospital, diagnoses before and after operation, and prognosis.Results Arthroscopic surgery was of benefit to diagnosis and treatment of osteoarthritis of knee. The average stage in hospital was 11±7 days. The following-up of 98 patients showed that 82 patients were excellent, 16 patients good and only 1 patients not up to standard.Conclusion Arthroscopic surgery has following advantages such as less invasive surgery, shorter stage in hospital, good curative effect in the near future.

Objective Based on the analysis of relevant factors on scores of the first clinical dietitian post-training examination (CDPTE) in China,to explore the clinical dietitians' post competency evaluation basis.Method 108 students who completed the clinical nutritionist training (60 physicians,nurse or technician 48) were imposed comprehensive evaluation designed according to the concept of post competency.Through analysis and comparison,the correlation factors of the candidates' passing rate and their mastering rate of the module were studied.Results The results of all the candidates' comprehensive theoretical examination increased with the degree and the source of the candidates.Among them,the college students' pass rate was 76.47％,undergraduates' pass rate was 86.21％,Graduates' pass rate was 96.97％;the pass rate in western region was 85％,the central part was 85.71％,the eastern part was 89.55％.All the candidates' knowledge module mastery rate in the comprehensive examination of the theory from high to low in order was:for hospital diet (73.7％),enteral nutrition and parenteral nutrition (72.7％),public nutrition (70.7％),nutrition screening and assessment (66.7％),common nutrition related diseases (65.4％),clinical nutrition related health students regulations,medical psychology and ethics basic knowledge (40.0％).The examination pass rate was related to the educational level of the examinee and the source area,while the knowledge module mastery rate was closely related to the work of clinical nutrition.Conclusion We concluded that the CDPTE could objectively reflect the candidate's clinical competence and professionalism and it was designed on the basic principle of post competency.CDPTE has a positive significance for scientific assessment of clinical dietician,guide for training,and evaluation of training effects as well.The scores of CDPTE can objectively reflect the examinees' clinical competence and professionalism and CDPTE can achieve the goal of evaluating the candidates' competency,and it is of practical significance for scientific evaluation of clinical practice,guiding learning and evaluating the training effect.

Objective To improve the outward appearanee in toe-to-hand transfer,a reshaped procedure of second toe was studied. Methods In reconstructing a finger with second toe transfer,a piece of flap from the fibular side of the second toe,or/and a H-shaped flap from the tibial of great toe were designed and transferred to the volar side in order to obliterate the constriction below the toe pulp. Results In 17 patients,22 fingers reconstructed with these procedure,ouly one rotation flap necrosis partly.The appearance of the newly reconstructed thumbs and fingers were improved,the pulp of reconstructed finger was similar to a natural finger, the narrow neck of second toe was well-stacked,and the interpbalangeal joint was straighten. Conclusion Reconstructed finger with this reshaped second toe is similar to a normal finger.
