Objective: To study the effect of early rehabilitation on motor function of upper and lower extremities and activities of daily living(ADL) in patients with hemiplegia after stroke; and to observe whether motor function recovery of upper and lower extremities is different. Method: 96 patients were randomly divided into two groups, rehabilitation group (48 cases) and control group(48 cases). Prospective method was used in this study. Patients in the rehabilitation group were given clinical treatment and regular rehabilitation training, while those in control group were given clinical treatment and unguided self- training. The evaluation was done in pre- treatment and post- treatment(6- 8 weeks) respectively.Motor function was assessed in Fugl-Meyer assessment(FMA), ADL assessed in Barthel Index. Result: The motor scores (measured by FMA) and ADL scores (measured by Barthel index) in the two groups were improved after 6-8 weeks treatment, but there was a significant difference between the two groups, the scores in the rehabilitation group were obviously superior to those in the control group (P ＜ 0.01 ). The mean of the Fugl-Meyer Scale (transferred to percentage of maximal motor scores) of the lower extremities was higher than that of the upper extremities pre-and post-treatment (P＜0.01). However, the improvement degree of FMA scores between upper and lower extremity had no statistical difference (P＞0.05). Conclusion:Early rehabilitation training of the patients with stroke hemiplegia may obviously improve motor function of the limbs and raise ADL scores. However, the degree of improvement in upper and lower extremity is similar in the first two months after early training.

ObjectiveTo evaluate the safety and efficacy of GM1 ganglioside treatment for persons with Parkinson's disease.Methods33 Parkinson's disease patients with a fluctuating response to levodopa received 100 mg GM1 ganglioside (used as add-on agent to the previous medication regimen) daily. Unified Parkinson's disease Rating scale (UPDRS) motor score and Activities of Daily Living (ADL) score were measure before and 2, 3 or 4 weeks after treatment. The side-effect of GM1 during treatment were observed. ResultsAfter 2, 3, 4 weeks of treatment, There was significant improvement in patients with GM1 treament on the UPDRS motor scores were (23.5±8.9), (22.8±8.3) and (22.5±9.1) respectively, which was improved compared with that before (36.7±10.2) (P<0.01). The ADL portion of the UPDRS at these time were (21.4±10.9), (20.3±9.5) and (20.6±10.2) respectively, also showed significant improvement compared with the baseline (30.5±12.1) (P<0.01). However, there was no significant differece between the scores that measured at the time spots 2 weeks after treatment.No side-effect had been observed.ConclusionGM1 ganglioside can improve neurologic function significantly in PD patients with fluctuating response to levodopa.

In order to understand the natural evalution of the motor function and the activities of daily living(ADL) in post stroke patients,and to provide scientific basis for the early treatment and rehabilitation training of the stroke patients,the motor function and ADL of 150 stroke patients without systematic rehabilitation training were evaluated at 5-6 week and 6 month of post stroke,respectively.The results showed that most patients had functional improvements.The functional recovery of upper limbs and especially hands was worse than that of lower limbs.The average ADL scores increased from 59.80 to 69.54,but the improvements were unsatisfactory.The results suggested that it is necessary to carry on the early rehabilitation training for the stroke patients fo that the patients motor function and ADL could improve more quickly and better to greater degree.

Objective To study the effect of early rehabilitation on motor function of upper and lower extremities and activities of daily living(ADL) in hemiplegics after stroke.Methods96 patients were randomly divided into two groups, rehabilitation group(48 cases) and control group(48 cases). Prospective method was used in this study. Patients in the rehabilitation group were given clinical treatment and regularly rehabilitation training, while those in control group were given clinical treatment and unguided self training, and the evaluation was done in pre treatment and post treatment(68 weeks) respectively. Motor function was assessed in Brunnstrom Grade, ADL assessed in Barthel Index. Results The motor scores (measured by Brunnstrom criteria) and ADL scores (measured by Barthel Index) in the two groups rised after 68 weeks treatment, but there was a significant difference between the two groups,i.e., the scores in the rehabilitation group were obviously superior to those in the control group(P<0.01). ConclusionEarly rehabilitation training on hemiplegics after stroke may obviously improve motor function of the limbs and rise ADL scores.

Objective To analyze the relationship between biochemical level and severity levels and clinical,duration of disease in patients with Parkinson Disease (PD).Methods 69 patients with PD and 69 healthy persons of similar sex and age were selected in the research.Serum uric acid and lipids levels were examined and compared.Results The serum uric acid,triglycerides,total cholesterol and low-density lipoprotein cholesterol (LDL-C) were (322.48 ± 66.18) μmol/L,(1.22 ± 0.86) mmol/L,(4.70 ± 0.92) mmol/L and (3.00 ± 0.85) mmol/L in control group,and (384.23 ± 88.28) μmol/L、(1.64 ± 0.94) mmol/L、(5.37 ± 1.31) mmol/L、(3.53 ± 1.03) mmol/L in control group.The differences are significant (t =-4.68,P =0.000;t =-2.74,P =0.007;t =-2.74,P =0.007;t =-3.49,P =0.001;t =-3.27,P =0.001).Serum UA concentration and high-density lipoprotein cholesterol (HDL-C),LDL-C were lower in patients with Parkinson's disease in duration of disease more than 3 years than those in duration of disease less than 3 years (t =3.373,P =0.001;t =2.440,P =0.017).The serum UA levels of any stages of PD patients were lower than the control group (P ＜ 0.05) according to Hoehn-Yahr staging.All lipid levels in early and middle stage PD disease patients were lower than those in control group (P ＜ 0.05).Serum UA,total cholesterol and HDL-C in female PD patients were (305.69 ± 54.25) μmol/L,(4.99 ± 0.95) mmol/L,(1.25 ± 0.27) mmol/L,and (339.76 ± 73.40) μmol/L,(4.41 ± 0.81) mmol/L,(1.06 ± 0.19) mmol/L in male patients.The difference is significant (t =2.198,P =0.031;t =-2.721,P =0.008;t =-3.266,P =0.002).Multivariate logistic regression models assessed lower uric acid concentrations is the risk of PD (OR =1.01,95％ CI 1.004 ～ 1.015,P =0.001).Conclusion Biochemical level changed differently in Parkinson disease and uric acid reduction could be a risk factor for PD.

Objective To investigate the correlation between the measurement methods of carotidcerebral pulse wave velocity (ccPWV) and the traditional method of brachial-ankle pulse wave velocity (baPWV).Methods A total of 136 healthy volunteers were divided into a youth group (20-39 years),a middleaged group (40-59 years),and an elderly group (more than 60 years) according to their ages.While detecting baPWV,transcranial Doppler ultrasound was used to simultaneously monitor the ipsilateral common carotid artery and the terminal segment of internal carotid artery.The time differences of the beating points of their cardiac cycles and the distanceses of the skin surfaces between the 2 probes were measured and ccPWV was calculated.Results The systolic blood pressure,pulse pressure and mean arterial pressure in the elderly group were signifificantly higher than those in the middle-aged group and the young group.The ccPWVs in the youth,middle-aged and elderly groups were 418 ± 52 cm/s,489 ±54 cm/s,and 599 ± 58 cm/s,respectively.The elderly group was significantly faster than the middle-aged group (t =7.308,P ＜0.001),and the middle-aged group was significantly faster than the youth group (t=6.758,P＜0.001).A Pearson correlation analysis showed that ccPWV was significantly positively associated with the age (r=0.847,P＜0.001) and baPWV (r =0.548,P ＜0.001).The multiple linear regression analysis showed that ccPWV was significantly positively associated with the age and diastolic blood pressure (partial correlation coefficients were 0.742 and 0.293respectively,P ＜0.001 and ＜0.010 respectively).Conchlusions ccPWV is a new measurement method for cerebrovascular stiffneas,and it has a good correlation with the traditional measurement method.

Objetive The present study was aimed to explore the risk factors of mid-term cognitive decline in pa?tients with indexed TIA/minor stroke (NIHSS≤3) in a Chinese hospital-based cohort. Methods We recruited all consec?utive Chinese TIA/minor stroke patients from July to December in 2012 and followed them up in stroke clinics at 3 and 18 months after indexed TIA/minor stroke. The outcome was defined as significantly cognitive decline at 18 months com?pared with that at 3 months. Results A total of 209 consecutive Chinese TIA/minor stroke cases completed their fol?low-up investigation. Among them, 24 (11.5%) exhibited significantly cognitive decline. The independent risk factors of cognitive decline post TIA/minor stroke were education years (OR=0.869,P=0.021), atrial fibrillation(OR=5.950, P=0.001) and multiple silent lacunar infarcts (OR=5.179,P=0.020). Conclusion It is necessary to evaluate the cognition among TIA/minor stroke cases and a close follow-up is required for patients with atrial fibrillation and multiple silent la?cunar infarcts frequently in order to decrease the risk of cognitive decline post TIA/minor stroke.

Objectives Brain atrophy plays a key role in post-stroke dementia. The current study aims to explore risk factors for brain atrophy in different regions in order to find the ultimate therapeutic strategy. Methods Consecutive stroke and/or transient ischemic attack (TIA) patients were recruited from July 2012 to June . The clinical features, neuro?imaging findings and risk factors were collected during hospitalization. Logistic regression analysis showed that, except for age, female gender (Odds ratio, OR=2.447, P=0.007) and the number of silent lacuna infarcts (OR=1.414, P=0.027) were independent risk factors for frontal lobe atrophy. Ischemic stroke history (OR=2.224, P=0.024) was the independent risk factor for parietal lobe atrophy. All of extra-/intracranial larger artery diseases (OR=2.584, P=0.015) and white mat?ter severity score (OR=1.112, P=0.007) as well as the number of silent lacuna infarcts (OR=1.158,P=0.042) were inde?pendent risk factors for medial temporal lobe atrophy. Moreover, diabetes (OR=2.109, P=0.001),atrial fibrillation (OR=1.934, P=0.015) and white matter severity score (OR=1.098, P=0.002) were independent risk factors for global brain atro? phy. Conclusion Risk factors for brain atrophy included diabetes,atrial fibrillation, silent lacuna infarcts and white mat?ter changes. We should pay more attention to those patients with above risk factors in order to slow down the progression of brain atrophy and also prevent them from dementia by early interventions.

Objective To analyze the immunostimulatory effects of cyclic dinucleotides ( CDN) on immune responses to a nasal spray influenza split virus vaccine and to evaluate its potential as a mucosal ad-juvant. Methods A H1N1 influenza split virus vaccine combined with different CDN was used for mouse immunization. Each mouse was intranasally immunized twice with 4. 5μg of hemagglutinin (HA) and 10μg of CDN with an interval of 21 d. Titers of hemagglutination inhibition ( HI) antibodies in serum, secretory IgA ( sIgA) in bronchoalveolar lavage fluid and IgG in serum were detected 21 d after the last immunization. Immunostimulatory activities of different CDN were compared. Effects of cyclic di-GMP ( c-di-GMP) and ch-itosan (CSN) on the immunogenicity of H1N1 and H7N9 influenza split vaccines were analyzed and com-pared. H1N1 influenza split vaccine combined with c-di-GMP or CSN was used to immunize mice. Three weeks after the last immunization, these mice were challenged with 10 times the median lethal dose ( LD50 ) of A/Puerto Rico/8/34 (H1N1) influenza virus. Survival rates of the mice were observed for 14 d. Results All three CDN induced high levels of HI antibodies and IgG in serum and sIgA in BALF. HI antibody sero-conversion rates were also higher than those of the control groups. c-di-GMP was superior to CSN in enhan-cing the immunogenicity of H1N1 and H7N9 antigens as higher titers of HI antibodies in serum and sIgA in BALF were induced. Conclusions CDN could enhance the immunogenicity of influenza antigens with better efficacy than CSN adjuvant.
