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.

Objective To analyze the syphilis epidemic characteristics and trends of Yongchuan District during 2010? 2015 to provide a basis for formulating the prevention and control strategy of syphilis.Methods The data of syphilis cases reported in Yongchuan District of Chongqing City during 2010-2015 were arranged,checked anal statisticallyanalyzed.Results The incidence rate of syphilis showed a reverse U type change trend from rising to declining,latent syphilis accounted for the highest proportion,congenital syphilis cases were decreased year by year.The analysis results showed that the constituent ratio of latent syphilis and congenital syphilis had statistical difference between 2010-2013 and 2014-2015(P＜0.05);syphilis high prevalent area was concentrated at the city and town area,while prevalence rate was slower in rural area.Most of syphilis patients were concentrated in the age group of 25-45 years old.There was no difference between women and men;syphilis cases generally had lower educational level,majority concentrated at the population of junior high school or below;the occupations in the syphilis patients were concentrated at the entertainment personnel,followed by migrant workers.Conclusion The incidence rate of syphilis is changed from rising to smoothly and steady decreased.It is necessary to adopt the pertinent prevention and control measures for the high-risk population.

Methods After making the models of cecal ligation and perforation,the SD rats were divided into two groups.The rats in the control group were administrated with parenteral nutrition.The rats in the experimental group were administrated with parenteral nutrition and probiotics via the needle jejunostomy and neck vein for 5 d.The feces in the cecum were cultured by anaerobic bacterial growth.The vena cava blood and the homogenated tissues of the lives,hungs and mesenteric lymph nodes were cultured to determine bacterial translocation. Results The quantity of normal intestinal bacteria in the experimental group and the control group had significant difference except Enterobacteriaceae.The quantity of L.acidophilus and Bifidobacteria in the experimental group were higher than those in the control group.The quantity of C.perfrigens,the potential pathogenic germ in the experimental group were lower than those in the control group(P

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 investigate the anxious and despondent emotion in patients suffering from chronic eczema,and its influence factor thereof.Methods:The patients suffering from chronic eczema were investigated with self-rating anxiety scale(SAS),self-rating depression scale(SDS)and evsenck personality questionnaire(EPQ).The healthy persons were investigated with SAS and SDS.The severity of pruritus and skin rash in patients suffering from chronic eczema was assessed by visual analogue scale (VAS)and eczema area severity index (EASI).Results:The scores of SAS and SDS were significantly higher in patients with chronic eczema than that of healthy persons(P＜0.01).The multivariate stepwise regression analysis result demonstrated that the factors influencing anxious emotion were in turn severity of pruritus,disease position and stability of emotion introverted-extroverted disposition.The factors influencing despondent emotion were in turn disease position,course of disease,concealing,stability of emotion and severity of pruritus.Conclusion:There was obvious anxious and despondent emotion in patients with chronic eczema.These emotions were closely correlated with psychosocial factors,severity of pruritus and skin rash.

Objective Thymic epithelial tumors(TET) consist of thymoma and thymic carcinoma. The purpose of this study was to investigate the diagnostic value of 18 F-fluorodeoxyglucose (FDG) coinci-dence SPECT imaging in TET. Methods 18 F-FDG coincidence SPECT images of 37 TET patients ( male 16, female 21, age range 24-82 years; mean age 55 years) were retrospectively analyzed according to the simplified WHO histological classification: high survival thymoma (types A, AB and B1 ), median survival thymoma (types B2 and B3 ), and low survival thymoma (thymic carcinoma). Qualitative visual interpreta-tion was based on foci of18F-FDG uptake'higher than that of normal mediastinum. Turnour/lung radioactivity ratio (TLR) was calculated from the counts of region of interest (ROI) drawn around the mass and over a comparable area of normal lung tissue in TET patients. The distribution of18F-FDG uptake was compared with the enhanced CT findings. TLR was also correlated with the Ki67-1abeling index. Statistical comparison for TLR in different groups were performed with variance analysis. Results Thirty-four TET were positive and 3 negative ( A, A, AB) by 18 F-FDG coincidence SPECT images. The differences among the 3 sub-groups were statistically significant (F=9.99,P<0.05). The TLR of these 3 subgroups was variable: 1.42±0.27, 2.13±0.74, 3.00±1.19, respectively. A close correlation (r=0.613, P=0.002) of the TLR with the Ki67 labeling index (n= 22) was found. In addition, 18 F-FDG coincidence SPECT detected two metastases ( anterior chest wall and right supraclavicular fossa lymph node) that were not identified on enhanced CT. Conclusions 18 F-FDG coincidence SPECT is useful in differentiating subgroups of thymic epithelial tumors and in identifying more invasive thymic lesions.18 F-FDG may be a novel tracer that ena-bles in vivo evaluation of cellular proliferation in human TET.
