Objective To observe the effect of electroacupuncture on hand dysfunction after stroke. Methods Forty hemiplegic patients after stroke were selected from a multi-center large-scale trail, belonged to rehabilitation group (n=20) and electroacupuncture group (n=20), who accepted routine rehabilitation and additional electroacupuncture, respectively, for six weeks. They were assessed with Brunnstrom Grade, Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT) and modified Barthel index (MBI) before treatment, two, four and six weeks during treatment, and twelve weeks after treatment. Results There were differences between two groups in scores of FMA, WMFT and total time to complete WMFT twelve weeks after treatment (t>1.900, P<0.05). There was no difference between two groups in scores of MBI and Brunnstrom Grade (t=0.532, Z<1.79, P>0.05), but electroacupuncture group seemed to improve more. Conclusion Elec-troacupuncture may improve the muscle strength for patients in flaccid paralysis, and promote the recovery of hand function for patients af-ter stroke.

Among them,only 49.51% needed calcium supplementation,only 79.37% held that they could have fruit during confinement in childbirth,as high as 66.02% went out after confinement,only 33.49% washed during puerperal,20.39% had over light anxiety. Conclusion It is necessary to reinforce health education and puerperal health guide to puerperal women in Chongqing to improve nutrition and health level and mental situation of puerperal women.

The purpose of this study was to study the effect of three different transfection reagents (Lipofectamine™ LTX & PLUS™, Lipofectamine 2000 and Nano-PAMAM-D) and three different testicular injection methods (rete testicular injection, seminiferous tubules injection and testicular interstitial injection) on the efficiency of production transgenic mice. After the mixtures of plasmid DNA (pEFP-C1) and transfection reagent were injected with different testicular injection methods, the sperm density, vitality, positive sperm rates and PCR positive transgenic mice rate were examined 30 days after injection. The results showed that the damage degree from slight to serious of three transfection reagents was Lipofectamine™ LTX & PLUS™, Lipofectamine 2000, and PAMAM-D. The sperm positive rates with green fluorescence of these three groups were 35.65%±0.69%, 12.86%±0.35% and 10.04%±0.20%, respectively. The PCR positive rates of transgenic newborn mice were 29.17%, 13.70% and 5.88%, respectively. Among the groups of different testicular injection methods, the damage degree from slight to serious was rete testicular injection, seminiferous tubules injection, and testicular interstitial injection, whereas the sperm positive rates with green fluorescence were 35.13%, 15.13%, and 0%, respectively. The PCR positive rates of transgenic newborn mice among different testicular injection groups were 33.3%, 12.5%, and 0.0%. The combination of rete testicular injection and Lipofectamine™ LTX & PLUS™ had the lowest toxicity and highest transgenic efficiency in the production of transgenic mice.

BACKGROUND:Which an ideal method to treat type Rockwood Ⅲ acromioclavicular joint dislocation is,traditional or surgical therapy,is still controversial.OBJECTIVE:To investigate the clinical effect of clavicular hook plate implantation on type Rockwood Ⅲ acromioclayicular joint dislocation.METHODS:A total of 56 patients with type Rockwood Ⅲ acromioclavicular joint dislocation were selected from Department of Orthopaedics of Yiling Hospital between December 2005 and June 2008.There were 42 males and 14 females,aged 16-65 years and mean age of 32 years.All patients were treated with clavicular hook plate implantation.Indicators including visual analogue scale (VAS),the United States shoulder and elbow surgeon score (ASES),and Constant and Murley scoring system were tested pre-operatively,one year postoperatively,before internal fixation,and 3 months after internal fixation;additionally,functional changes of the shoulder joint and complications were analyzed before and after clavicular hook plate implantation.RESULTS AND CONCLUSION:The surgery and following-up were successfully achieved in 56 cases.The following-up lasted for 15-30 months,with the mean time of 20 months.The internal fixation was taken out at about 1 year after implantation.Coracoclavicular ligament was repaired in 32 cases but not in the 24 cases.Two patients with acromioclavicular joint dislocation recurrence were excluded,and coracoclavicular ligament therapy was not performed.Shoulder pain,foreign body sensation,and internal fixation failure occurred in two cases.One year after operation,VAS was decreased compared with that before operation,but ASES and Constant and Murley score were significantly increased (P＜0.01).At three months after internal fixation,VAS was decreased compared with that at 1 year after operation,but ASES and Constant and Murley score were increased (P＜0.05).The results demonstrated that clavicular hook plate implantation for treating type Rockwood Ⅲ acromioclavicular joint dislocation is simple and less invasive,thus it is an ideal internal fixation.

Objective To assess the predictive value of short-latency somatosensory evoked potential (SSEP) in the acute phase of stroke regarding functional recovery. Methods One hundred and fifty stroke patients were included. SSEPs were recorded on the first 7 days after stroke, and the patients were then stratified into groups with absent, abnormal and normal responses. Clinical state was determined according to the NIH stroke scale (NIHSS), the Fugl-Meyer assessment (FMA), the modified Barthel index (MBI) and the modified Rankin scale (MRS). SSEP was followed up at 1, 3, 6 and 12 months. Results The NIHSS and FMA scores were significantly different comparing any two groups or at different times in the same group. The median SSEP N20 latency and tibial nerve SSEP P40 latency during stroke were positively correlated with MRS scores 12 months later but negatively correlated with MBI results. The ADL results 12 months after stroke were used to evaluate functional recovery, and the prediction rate of the SSEP results alone was 40.8% , however the rate improved to 44.2% when SSEP results were combined with FMA scores and became 46.1% when SSEP, FMA and MRS results were all considered. Conclusion SSEP has independent predictive value regarding functional recovery after stroke. Combined assessment of initial FMA, MRS and SSEP substantially improves the predictive power for stroke prognosis.

Objective To search MRI features of patients with HIV-negative cryptococcus meningoencephalitis (CM)and evaluate the value in judging the prognosis of CM.Methods The findings of cranial MRI and prognosis were retrospectively analyzed in 19 cases with India-ink capsule staining-proved HIV-negative CM in our department.The prognosis was evaluated by Glasgow Outcome Scale:score 1=death,score 2=persistent vegetative state,score 3=severe disability,score 4=moderate disability,score 5=good recovery. The patients with score 1-3 were classified as the group of poor prognosis,while those with score 4,5 as good prognosis.Results Abnormal manifestations on cranial MRI were observed in 84.2%(1 6/1 9)cases,meninges enhanced in 84.2% (1 6/1 9),brain edema in 31.6%(6/1 9),brain parenchyma lesion in 47.4% (9/1 9 ),vasculitis in 5.2% (1/1 9 ).The mean duration of follow-up was 3.5 years,The prognosis of 5/9(44.4%)cases with brain parenchyma lesion confirmed by cranial MR was poor.Conclusion The MRI manifestation of HIV-negative CM is diverse,and brain parenchyma lesion confirmed by cranial MRI may associated with poor prognosis.
