Objective To observe the effect of electromyographic biofeedback therapy on hemiplegia of patients with cerebral infarction.Methods 122 hemiplegic patients were divided into observed group (n=61) and control group (n=61). The two groups all received physical therapy 6 times a week for two weeks in addition to regular medication. In the meantime the observed group received electromyographic biofeedback. All patients were evaluated with NIHSS, Fugl-Meyer Assesment(FMA) and Barthel Index(BI). Results The improvement in the observed group was greater than in control group in NIHSS, FMA and BI.Conclusion The eletromyographic biofeedback can improve motor function of hemiplegic patients and do benefit their activities of daily living.

Objective:
To examine the causal relationships between obesity, peripheral blood lipid indicators and non-small cell lung cancer (NSCLC) using Mendelian randomization (MR) method, so as to provide the basis for developing NSCLC prevention and control strategies.
Methods:
Genetic variation data of three obesity evaluation indicators, including body mass index (BMI), body fat ratio (BFR) and waist-to-hip ratio (WHR), and seven peripheral blood lipid indicators, including triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB) and lipoprotein a [LP (a)] were collected through genome-wide association studies (GWAS) and related public databases. Potential causal relationships between obesity, peripheral blood lipid indicators and NSCLC were analyzed using inverse-variance weighted (IVW) method and multivariable MR analysis upon a random effect model. Heterogeneity and horizontal pleiotropy of instrumental variables were evaluated using Cochran's Q test and MR-Egger regression.
Results:
There was statistically association between BMI with NSCLC (OR=1.256, 95%CI: 1.087-1.451); there were no statistically associations between BFR, WHR, seven peripheral blood lipid indicators and NSCLC (all P>0.005). There was heterogeneity in the association between BMI, BFR, WHR, TG, HDL-C and NSCLC (all P<0.05); no horizontal pleiotropy of instrumental variables was found (all P>0.05). There was no statistically association between BMI and NSCLC after adjusting BFR (OR=1.367, 95%CI: 0.878-2.128); there was still statistically association between BMI and NSCLC after adjusting WHR and peripheral blood lipid indicators (both P<0.05).
Conclusions
The increase of BMI is associated with the increased risk of NSCLC incidence. BFR may be a potential influencing factor for the association between BMI and NSCLC.

BACKGROUND: Logistic analysis of multi-ordered response-variable is used to probe into from another view the interrelationship between lead content in fetus faeces and neurobehavioral development under exposure to low-level lead in uterus.OBJECTIVE: To probe into multi-factors of neurobehavioral development in neonates and the sensibility.DESIGN: The total score of neurobehavior in neonates was taken as dependent variable and 24 indexes were as independent variables, such as induced factors, lead in umbilicus blood and lead in fetus faeces in questionnaire. Logistic progressive regression of multi-ordered response-variables was used in analysis and corresponding factors were screened at level of P=0.10.SETTING: Wuhan University of Science and Technology, Laboratory Room of Occupation Disease and Epidemic disease in Tongji Medical College of Huazhong University of Science and Technology and Occupation Hospital of China First Metallurgical Construction General Company.PARTICIPANTS: Totally 103 full-month borne and healthy neonates were randomized in Department of Gynecology of one occupation hospital in Qingshan District of New-type Industry Area of Huanhan City from January to October 1999 as the objects. The relatives agreed with topic research and questionnaire investigation and they provided neonatal faeces and received neonatal tests on time.off the umbilicus and preserved in freezing in refrigerator at -4 ℃. The faeces in 24 hours after birth was collected and the lead contents of umbilicus blood and faeces were assayed with graphite furnace atomic absorpBehavioral Neurological Assessment (NBNA) was used in examination on the 3rd day after delivery. Simultaneously, the self-designed questionnaire was adopted in the investigation for parturients. The questionnaire involved other possible factors of neonatal neurobehavioral development, including dependent variables, concerning to states of family, society, environment and health that affected neurological development in neonates and lead contents in umbilicus blood and faeces. Scores of neonatal neurobehavior were taken as response variables. Finally, the corresponding factors were screened.MAIN OUTCOME MEASURES: To screen the factors of neurobehavioral development of neonates.RESULTS: Totally 103 cases entered result analysis. Six factors were selected in the model, named pregnant weeks, the month of drug administration in pregnancy, hemoglobin, emotions in pregnancy, lead level in fetus faeces and drug administration.CONCLUSION: Neonatal neurobehavioral development was related to multiple factors. Good nutrient in pregnancy, long pregnant weeks and good emotions in pregnancy benefit neurobehavioral development of neonates. Drug administration during pregnancy is disadvantageous in neonatal neurobehavioral development, especially the medication at the early phase of pregnancy. The increased lead content in neonatal faeces does not benefit neonatal neurobehavioral development.

Objective To investigate the effect of small direct‐current electrical stimulation on migration and invasion related MMPs/TIMPs expression of trophoblast cells .Methods The trophoblast cells were exposed to the direct current electrical field at 150 mV/mm for 5 and 10 hours .Cell images were recorded with continuous photographing and analyzed by image analyzer .The ex‐pression levels of MMP2 ,MMP9 ,TIMP1 and TIMP2 were measured using quantitative RT‐PCR and Western blot .Results In non‐electrical field culture trophoblast cells migrated slowly with random directions .Trophoblast cells cultured in media containing 10% calf serum with the application of 150 mV/mm direct current electrical stimulation ,showed marked cathodal migration (P<0 .01) ,the cell body stretched ,perpendicular to the direction of the electric field .Compared with the non‐electrical field stimulation controls ,trophoblasts under the electrical field stimulation had the increased MMP2 mRNA and protein expression (P< 0 .05) , while MMP9 ,TIMP1 and TIMP2 had no obvious changes of mRNA or protein expressions .Conclusion Physiological direct‐cur‐rent electrical fields might induce directed migration and perpendicular orientation of trophoblast cells .The enhanced MMP2 expres‐sion may play an important role in the migration and invasive activity of trophoblast cells in small electrical field .
