Objective To study the effect of motor imagery therapy combined with conventional physical training on hemiplegia lower extremity function in stroke patients with hemiplegia.Methods Thirty hemiplegic patients meeting the eligible criterions were randomly divided into two groups: a treatment group (n = 13 ) and a control group ( n = 17).All subjects accepted conventional rehabilitative treatment.Patients in treatment group were treated with motor imagery therapy after physical training, while the patients in control group were treated with physical training only.Motor function was measured by the percentages of changes in maximum loading on affected lower limb (PL%), Barthel index (BI), 5m maximum back and forth walking speed (5m MBFWS), Berg balance scale ( BBS), Fugl-Meyer motor assessment ( lower limb) (FMA-L) before the beginning of training and at the end of sixweek training.Results In both groups, all measurements at the end of training improved significantly ( P < 0.01 )compared to that at the beginning of training.After the whole training course, PL% and 5m MBFWS (m/s) in treatment group were significantly better compared to those in control group( P < 0.05 ), and the other measurements were not statistically significant between two groups( P > 0.05 ).Conclusion Motor imagery therapy had positive effect on hemiplegia lower extremity function of sub-acute stroke patients.

Objective To predict the prognosis after acute cerebral infarction using a combination of indicators. Methods Two hundred and seventeen patients with acute cerebral infarction admitted from October 2005 to December 2008 were studied. Logistic regression analysis of the data from 112 of the patients admitted from October 2005 to March 2007 was used to select 20 indicators for study. The indicators were combined into prognostic indexes using a multi-layer perception (MLP) neural network (NN) model. Data on the subsequent 105 patients were usedto appraise the model. Results The agreement of the prediction results of the NN model with the real recovery observations was rated as "excellent" in 39 cases, "OK" in 27 and "bad" in 32. The sensitivities were 95.1%,87.1% and 96.9% respectively. On average, the differences between the predicted results with the NN model andthe real recovery were not significant. Conclusion The NN model delivered good precision in predicting the outcome of acute cerebral infarction and it is worthy of further investigation.

Objective To investigate the efficiency of transduction of recombinant adenovirus-mediated human endothelial nitric oxide synthase (eNOS) into lung tissue by repeated intratracheal transfection in rats.Methods Sixty 3-4 month old male Wistar rats weighing 220-280 g were randomly divided into 2 groups:control group (group C,n =10) and eNOS gene transduction group (group T,n =50).The animals were anesthetized with intraperitoneal 10％ chloral hydrate 35 mg/kg,tracheally intubated and mechanically ventilated (VT 2.5 ml,RR 60 bpm,FiO2 1.0).Recombinant adenovirus carrying human eNOS gene was given as gift by Professor Gerard from Texas University,Southwest Medical Center.In group T 50 μl of the recombinant adenovirus in concentration of 5 × 109 PFU/ml was instilled into trachea every 5 minutes for 12 times,while in group C equal volume of vector conservation solution was instilled instead.Pulmonary arterial blood samples were obtained at 2,5,7,14 and 21 d after intratracheal transfection (n =10 at each time point) for determination of serum NO concentration.The animals were immediately sacrificed after blood sample collection for determination of expression of eNOS protein in the lung tissue and RNA.The eNOS expression in the trachea,bronchus,lung,liver,spleen and kidney was detected by immuno-histochemistry.Results The serum NO concentrations were significantly higher at all time points in group T than in group C.The eNOS expression was detected in the epithelial cells of trachea and bronchi,and endothelial cells of alveoli and pulmonary blood vessels in group T but not in group C.eNOS expression was not detected in liver,spleen and kidney at 7 d after intratracheal transfection in group T.Conclusion Human eNOS gene mediated by recombinant adenovirus was transducted into rat lung tissue with normal enzyme activity by repeated intratracheal administration without being detected in distant organs.

Objective To study the characteristics of plasma adiponectin levels exhibiting in gestation women and newborns, as well as the relationships between adiponectin levels and fetal birth weight. Methods Totally 98 subjects have been considered in this study, in-cluding venous blood samples of 36 healthy non-pregnant women (control group), 31 uncomplicated pregnant women (pregnancies group) and the cord blood samples taken at delivery of their singleton infants born at term (newborns group). The concentrations of adiponectin and insulin were determined by radioimmunoassay technique. And SPSS was used for statistical analyses. Results The adiponectin level in women of late period of gestation (WLPG) (11.10±5.72)g/ml was lower than that of other two groups, and the newborns average cord plasma level of adiponectin was (30.71±12.77) g/ml significantly higher than that of the control group (16.52±6.87) g/ml. The adipone-ctin level for WLPG was correlated with FINS and HOMA-IR (r = -0.411, -0.393, P <0.05). The adiponectin level in cord plasma was positively correlated with birth weight(r = 0.416, P < 0.05). The adiponectin level in WLPG was correlated neither with the adiponec-tin level nor body weights of their newborns. Conclusions The average cord plasma adiponectin level of newboms is significantly higher than that of the control group and WLPG. It is positively correlated with birth weight, which suggests that adiponectin may be involved in reg-ulating fetal growth. The adiponectin level in WLPG is correlated neither with the adiponectin level nor body weights of their newborns.

ObjectiveTo evaluate the intermediate term efficacy of posterior stabilized (PS) total knee arthroplasty(TKA) and posterior cruciate-retaining(CR) TKA and explore the clinical related problem.MethodsThe clinical data of 84 patients (87 knees) who treated with primary TKA from May 1992 to May 2006 were analyzed retrospectively.The intermediate term efficacy was compared between PS TKA (PS group,41 cases with 43 knees) and CR TKA (CR group,43 cases with 44 knees).ResultsAll the patients were followed up for 5-10(7.6 ± 1.5 ) years,no infection,dislocation or neurovascular injury occurred in both groups.But 1 knee occurred intraoperative posterolateral femoral condyle fracture in PS group.The lateral retinacular release rate was 2.3％ ( 1/43 ) and 2.3％ (1/44) in PS group and CR group,respectively.The incidence of anterior knee pain was 4.7％(2/43 ) and 4.5％(2/44) after 6 months surgery in PS group and CR group.The incidence of anterior knee pain was 0 at the end of follow-up in both groups.There was no significant difference in the lateral retinacular release rate and the incidence of anterior knee pain between two groups (P ＞0.05).The range of motion and American knee society score(KSS) was similar and no statistical difference was found between two groups(P ＞ 0.05 ).The incidence of patellar tilt or subluxation in X-ray was 2.3％ (1/43) and 2.3％ (1/44) at the end of follow-up in PS group and CR group.There was no significant difference between two groups (P ＞ 0.05 ).At the end of follow-up,no osteolysis,X-ray radiolucent zone and prosthesis loosening were found in both groups.There was no revision owing to loosening or other reasons.ConclusionsThe intermediate term efficacy of PS TKA and CR TKA is near a tie.However,the future efficacy still need further follow-up.

Objective To explore the phenomenon of gene silence of SLC5A8 in breast cancer.Methods Thirty-two patients suffered with breast cancer,hospitalized from June 2014 to June 2015 in affiliated hospital of Hebei university,were collected with the cancer tissue and normal specimen.Real-time quantitative PCR method was used to detect SLC5A8 gene transcription.Paired t-test and-test were used to anaylsed the results.Results Twenty cases of breast cancer tissues (62.5％) have no SLC5A8 gene transcription product,normal breast tissue adjacent to carcinoma specimens that had no product gene transcription was only five (12.5％).SLC5A8 inactivation rate of cancer tissue was significantly higher than normal tissue adjacent to carcinoma (P ＜ 0.05).The SLC5A8 mRNA transcription level of cancer tissue was significantly lower than the normal (P ＜ 0.05).Conclusion SLC5A8 gene transcription silence is the important events in the process of breast cancer occurrence and development.
