Positive outcomes have been reported about the transcranial magnetic stimulation for aphasia. This paper reviewed the relat-ed literatures about repetitive transcranial magnetic stimulation used in clinical and research, and discussed the possible mechanisms in the recovery of aphasia, and the roles of hemispheres in brain.

Objective In order to investigate the interactions between the activities of daily living of children with post poliomyelitis and depression of their parents.Method 40 cases whose children were with post poliomyelitis were tested by SDSCR.Children's activity of daily living were tested with Barthel's index.Result 65％ of parents whose children with post polimyelitis were depression.Their symptoms of depression were mainly moderate level.There are marked difference comparing with the domestic normal analyzing model.The activities of daily living of the post poliomyelitis's children was worse,the older their parent's age was the higher the incidence of depression occurred was.Conclusion We should pay attention to their parents emotion changes when we carry out the community rehabilitation of post poliomyelitis's children,and strive them for positive coperating our rehabilitation training.

Objective To investigate the effect of isoflurane pretreatment on hypoxia/reoxygenation (H/R)-induced syndecan-1 shedding from human umbilical vein endothelial cells (HUVECs) . Methods HUVECs were cultured in EMB-2 medium and randomly divided into 3 groups ( n = 32 each) : control group (group C), H/R group and isoflurane pretreatment group (group I). H/R was produced by 4 h exposure of HUVECs to hypoxia followed by 2 h reoxygenation in H/R and I groups. HUVECs were exposed to the mixture of 5% CO2 and 95% O2 for 30 min and then cultured in normal culture atmosphere (21% O2) in group C. In group I, HUVECs were expased to 1.73% isoflurane and incubated for 30 min before H/R. The syndecan-1 expression, concentrations of shed syndecan-1 in the medium, and cell permeability and viability were measured at the end of reoxygenation. Results Compared with group C, the shed syndecan-1 concentration in the medium and cell permeability were significantly increased, while the syndecan-1 expression and cell viability decreased in H/R and Ⅰ groups ( P ＜ 0.01) . Compared with group H/R, the shed syndecan-1 concentration in the medium and cell permeability were significantly decreased, while the syndecan-1 expression and cell viability increased in group Ⅰ (P ＜ 0.01) . Conclusion Isoflurane pretreatment can protect HUVECs against H/R injury through inhibiting the syndecan-1 shedding.

Objective:To study the feasibility of electronic gingivoplasty on the subjects suffering from high blood sugar or blood coagulating dysfunction on rat model.Methods:Electronic gingivoplasty was performed in 10 SD rats with high blood sugar and 10 with blood coagulating dysfunction on the right side of mandible and scalpel gingivoplasty on the left.For each group of diseased rats 10 healthy rats were used as the controls. Gingival tissue slices of the rats with high blood sugar and the controls were obtained 1,24, 72 hours, one and two weeks after operation respectively, and processed for histological observation. The bleeding condition were evaluated with paper tips during the operations on the rats with blood coagulating dysfunction and the controls.Results:The process of histological reaction in the tissues of operation area after electronic gingivoplasty was basically similar to that after scalpel gingivoplasty. Electronic surgery caused more slight inflammatary reaction than scalpel surgery in high blood sugar group. The amount of bleeding during electronic surgery was significantly smaller than that during scalpel surgery in blood coagulating dysfunction group.Conclusion:Electronic surgery is feasible for gingivoplasty on the subjects with high blood sugar or blood coagulating dysfunction.

Objective To investigate the technique of drain air, cryotherapy, and explant (DACE) of operation for superior bullous retinal detachment (SBRD). Methods In the DACE procedure, drainage and air or balanced salt soultion (BSS) injection were carried out first, with the intention of flattening the retina before localization of retinal hole, cryotherapy out of choroid and scleral buckling. Results In 42 SBRD eyes, 40 underwent the operation with DACE technique. In 23 eyes injected with BSS instead of air, 5 should be injected air due to no avail for flattening deeply retinal detachment, and 1 needed scleral buckling due to new retinal tear after DACE procedure two weeks. During the follow up, all retinae attached. Conclusions The DACE technique is very useful and effective in upper ballooned retinal detachment due to single hole or breaks localized in small area between the 10 and 2 o′clock meridiant. BSS instead of air injection can eliminate the difficulty of observation of retinal breaks from the presence of air in some cases.

Objective To observe the effect of Wuyaojing granules(WYJG) on immunological function of mice.Methods Mice were randomly divided into six groups:the high-dosage WYJG group(6.0g/kg),the midst-dosage WYJG group (2.0g/kg),the low-dosage WYJG group(1.0g/kg),the Lindera aggregate group (0.9g/kg),the korean Ginseng group (2.0g/kg) and the normal control group(H2O).After a period of 30-day treatment,the effects of WYJG on the T lymphocyte transformations capacity induced by ConA,delayed hypersensitivity leaded by DNFB,the number of lymphocyte B,serum level of hemolysin and NK activity were observed. Results The high-dosage and the low-dosage WYJG could significantly increase T lymphocyte transformations capacity induced by ConA(P0.05).Conclusion WYJG can significantly increase T lymphocyte transformations capacity induced by ConA and strengthen delay hypersensitivity leaded by DNFB.

ObjectiveTo observe the clinical effects of locking proximal humerus plate(LPHP) in the treatment of complex proximal humeral fracture of aged patients and to analyze the influencing factors. Methods Among 39 cases with complex humeral fractures (aged 60-83 years),there were 29 cases with three-part fractures and 10 with four-part fractures according to the Neer classification.They were operated by LPHP via deltoid-pectoral approach. Neer numerical rating system was employed to evaluate postoperative function of shoulders.Results39 cases were followed up for average of 16 months.According to Neer numerical rating system,the excellence rates of three-part fractures and four-part fractures were 86.2％ (25 cases) and 50.0％ (5 cases),respectively,with total excellence rate of 76.9％(30 cases). Age (OR =1.314, P＜0.05) and fracture type ( OR =1.295, P＜0.05)ofpatientswereindependentriskfactorsforprognosis of proximal humeral fracture of aged patients by multiple logistic regression. Conclusions LPHP is an effective implant for treating complex proximal humeral fracture of aged patients,with age and fracture types as important risk factors of prognosis.<英文关键词>=humeral fractures

Objective To establish an experimental choroidal neovascularization(CNV)model in brown norway(BN)rats by laser infusion in order to study the evolution of CNV during 3 weeks with intravitreaI injection of 1 μl(25 μg)bevacizumab,and make a preliminary investigation of the treatment effect of bevacizumab on experimental CNV. Methods Four groups of 48 BN rats were photocoagulated by krypton laser in 1 eye to induce CNV model in 1 eye,in which 4 groups received 1 μl(25 μg)bevacizumab intravitreal injection 1 week after photocoagulation and the other groups received the same volume intravitreall injection of balanced salt solution(BSS)as control.Fundus fluorescein angiography(FFA)examinations were taken on 1,2,3 week and the eyes were enucleated and processed for histopathologic examination.The areas of CNV were measured in the early phase of FFA.FⅧ-Rag protein was investigated with immunohistoehemistry and was semiquantkatively analyzed. Results The area and the leakage of CNV in bevacizumab treated BN rat eyes were obviously reduced as compared with the control group at each interval.In the treatment group,the expression of FⅧ-Rag was depressed.The examination of FⅧ-Rag and FFA verified the depression of CNV as compared with the control group at each interval.The density of treatment was lower than of control group(P＜0.01).After bevacizumab treatment for 2 weeks,the area of CNV and the expression of FⅧ-Rag were decreased[(0.920±0.634)mm2 and 35.57±10.52,respectively),as compared with the control group[(2.489±0.590)mm2 and 175.37±25.20]. Conclusions Intravitreal bevacizumab injection can inhibit the development of CNV.
