Nowadays, for gait instability phenomenon, many researches have been carried out at home and abroad. However, the relationship between plantar pressure and gait parameters in the process of balance adjustment is still unclear. This study describes the human body adaptive balance reaction during slip events on slippery level walk by plantar pressure and gait analysis. Ten healthy male subjects walked on a level path wearing shoes with two contrastive contaminants (dry, oil). The study collected and analyzed the change rule of spatiotemporal parameters, plantar pressure parameters, vertical ground reaction force (VGRF), etc. The results showed that the human body adaptive balance reaction during slip events on slippery level walk mainly included lighter touch at the heel strikes, tighter grip at the toe offs, a lower velocity, a shorter stride length and longer support time. These changes are used to maintain or recover body balance. These results would be able to explore new ideas and provide reference value for slip injury prevention, walking rehabilitation training design, research and development of walking assistive equipments, etc.

Objective:To study the reliability, validity of PANSS(Chinese version) and its implication.Methods:105 schizophrenic patients were recruited and were evaluated using PANSS. The principle component analysis and reliability analysis were used to study the factor structure and internal reliability, homogeneity among items.Results:Factor analysis resulted in a five-factor: negative, positive, excitement-hostile, anxiety/depression, cognitive defect. The internal consistency reliability was 0.87 (Cronbach ?). The internal consistency reliability of the 5 dimensions ranged from 0.74～0.90.Conclusion:The structure, validity and reliability of PANSS (Chinese version) are acceptable. PANSS can be used to assess the symptoms of schizophrenia in Chinese patients.

Objective o observe the therapeutic effects of suspension-assisted functional rehabilitation training of motor function for patients with cerebral infarction. Methods Ninety-six patients with cerebral infarction were divided randomly into a treatment group and a control group. All patients were given routine medical treatment and routine limb movement therapy. Those in the treatment group also used an electrically-driven suspension device to aid in their functional rehabilitation training. The patients were assessed with a simplified Fugl-Meyer Motor Functional Assessment (S-FMMFA), and using the Postural Assessment Scale for stroke patients ( PASS), the Barthel Index (BI) and the 6-minute walking distance test before and after treatment and at a 6-month foliowup. Results The average S-FMMFA, PASS, BI and the 6-minute walk results in the treatment group were all significantly better than those in the control group. Conclusions Suspension-assisted training can significantly help improve limb movement function and ADL performance in cerebral infarction patients.

The levels of the antibody response against,classic swine fever (CSF) vaccine were measured by blocking ELISA at different time for pigs vaccinated with CSF vaccine (CSFV group,n= 3),pigs inoculated with porcine eircovirus type 2 (PCV2) and with CSF vaccine two weeks later (when PCV2 viremia was detected by PCR,PCV2/CSFV group,n=3),or inoculated with both CSF vaccine and PCV2 at the same time (CSFV/PCV2 group,n=3),respectively.And distribution of genome or antibodies specific to PCV2 of the PCV2 infection group,PCV2/CSFV group and CSFV/PCV2 group were also detected by indirect ELISA or PCR,respectively.The results showed that experimental infection of PCV2 was successful.In pigs inoculated with both PCV2 and CSF vaccine,the antibody response to CSF vaccine was significantly lower than that of animals treated with CSF vaccine vaccination alone at 52 days postinoculation (DPI).The average titers of antibodies against CSFV in animals of CSFV group were obviously higher than those of the PCV2/CSFV or CSFV/PCV2 group at 49 and 52DPI,respectively.The positive rate of antibodies against CSFV in pigs of CSFV group was 100% in comparison with that of animals inoculated with PCV2 and the vaccine (only 67%).The results suggested that the infection of PCV2 could suppress the antibody response to classical swine fever vaccine.

Objective:To investigate the application of photoplethysmogram in analyzing the fingertip pulse amplitude volume (PAV)to evaluate the endothelial function in diagnosing coronary heart disease,and to clarify its relationship with the risk factors of cardiovascular diseases.Methods:Total 409 patients with chest pain accepted coronary angiography (CAG)were selected and diveded into positive group (CAG+)(n=288)and negative group (CAG-) (n = 121)according to angiographic results.Fingertip photoplethysmogram was used to analyze the fingertip PAV by the way of applying endothelial function diagnostic after reactive ischemia,and the relationship between the PAV value and the risk factors of coronary heart diseases was analyzed,and the critical reference value of prediction index of coronary heart disease was determined.The risk factors such as age,gender,serum total cholesterol (TC ), low density lipoprotein (LDL ), high density lipoprotein (HDL ), non-HDL, serum triglyceride (TG),hypertension,diabetes,smoking,family history of coronary heart disease,body mass index (BMI)of the subjects in various groups were analyzed,and the relationship between the risk factors of coronary heart disease and PAV was analyzed by Logistic regression analysis.Results:The PAV of patients in CAG+group was significantly lower than that in CAG-group (P <0.01).The peak point of PAV was<1.37,if PAV<1.37 was used to predict the coronary heart disease,the predictive sensitivity,the specificity,the positive prediction and the negative prediction were 74.65%,44.63%, 76.24%, and 42.52%.The Logistic regression analysis showed that PAV was negatively associated with hypertension,smoking history,TG (OR= 1.476,OR=2.002, OR = 1.844;P < 0.01 ). Conclusion: PAV is associated with coronary heart disease and its risk factors (hypertension,smoking history,TG),and PAV=1.37 can be used as the peak point to predict the coronary heart disease.

The TNA mRNA expression in 33 samples of cervical carcinoma and 28 samples of condyloma have been observed by using ~3H and Digoxigenin labeled TNF—? cDNA probes and in situ hybridization technique, we found that the results of in situ hybrdfzation with these two kinds of labeled probes were alike, the sensitivity with ~3H labeled probe was slightly higher than that with Digoxigenin labeled probe. Nevertheless, the nonisotope probe would be used more and more in future because of its safety, rapidity and convenience in work.
