ObjectiveTo study the rehabilitative effects and pathological changes in rats after acute cerebral infarction. Methods 30 male Wister rats were randomly divided into 3 groups :Group A(sham group),Group B(model group) and Group C(rehabilitation group). Animal model was made by the middle cerebral artery occlusion(MCAO).For each group, Bederson Neural Function was scored and balancing wood,rotating bar,and net screen were tested at 24 hours,3 days and 7 days after operation respectively. On the 7th day after operation, pathological change of brain tissue was observed. ResultsCompared with Group A, Bederson Neural Function scores of Group B,C indicated significant differences at each time (P<0.01).The abilities of grasping, walking and coordinating of all the groups after 24 hours by operation handicapped, however with time continuing,every function of Group A restored and that of Group B or C improved partly,but showed significant difference compared with Group A(P<0.01).After 3 days by operation,balancing wood test of Group C was better than that of group B(P<0.05),after 7 days,except Bederson Neural Function score,there were difference between Group C and B(P<0.05 or P<0.01).After 7 days by operation,compared with Group A,brain tissue of infarction area in Group B indicated significantly edema, neural cells decreased. Compared with Group B, the edema in Group C decreased and neural cells increased.ConclusionsRehabilitation therapy can improve the MCAO rats' ability of equilibrating, grasping and walking, and decrease edema, increase neural cells in infarction areas.

ObjectiveTo observe effects of rehabilitation training on behavior and sensory evoked potential of rats with acute cerebral infarction.Methods30 male Wistar rats were randomly divided into sham operation groups (group A), model group (group B), and rehabilitation group (group C). Animal model was made by blocking the middle cerebral artery (MCA). For each group, the Bederson Neural Function was scored and balancing wood, rotating bar, and net screen were tested at the 24 hours, 3rd day and 7th day after operation respectively. The sensory evoked potential (SEP) latency of each group was also tested right after operation and on the 7th day after operation.ResultsComparing with group A, Bederson Neural Function scores of groups B and C indicated significant differences at each time (P<0.01). The ability of grasping, walking and coordinating of all groups handicapped 24 hours after operation, however, with time continuing, every function of group A restored and that of group B or C improved partly, but showed significant difference compared with group A (P<0.01). On the 3rd day after operation, balancing wood test of group C was better than that of group B (P<0.05), on the 7th day after operation, except Bederson Neural Function scores, there were significant difference between groups C and B (P<0.01 or P<0.05). Right after operation, compared with group A, the SEP latency of group B and C showed significant difference (P<0.01), on the 7th day after operation, the SEP latency of group C improved significantly compared with itself right after operation (P<0.01).ConclusionThe rehabilitation training can improve the MCAO rats' ability of equilibrating,grasping and walking and adjust the abnormal latency of SEP after MCAO, and prevent the nerve cells from damage caused by ischemic trauma.

ObjectiveTo investigate the reliability and validity of Chinese Rehabilitation Research Center Standard Aphasia Examination (CRRCAE) among patients with aphasia after cerebral injury. Methods40 patients were measured using the CRRCAE. For reliability, interclass correlation coefficients were analyzed. For validity, the correlation coefficients of the aphasia quotients and 4 items of CRRCAE and Western Aphasia Battery (WAB) were analyzed.ResultsThe interclass correlation coefficients>0.9, while the Cronbach α of total scale was 0.9411, the scale of the comprehension was 0.8677,the scale of express was 0.8889. CRRCAE had positive relationship with WAB(with the aphasia quotients, r=0.948,P<0.01). The effect size statistics scale was 0.94.ConclusionCRRCAE shows a good retest reliability and good internal consistency. The total scale of CRRCAE can be correlated with serious level of aphasia effectively.

Objective To investigate the prevalence of mutation in the locus 306 of embB gene in multi-drug resistant (MDR) Mycobacterium tuberculosis (TB) and evaluate the prospects for using it as a molecular marker to detect MDR-TB.Methods The 291 strains enrolled in this study were from the reference laboratory of Shanghai municipal centers for disease control and prevention, all of which had been tested for drug susceptibility.Mutation in embB 306 was screened both by amplification refractory mutation system (ARMS) and DNA sequencing.The mutation frequencies of embB 306 in the sample groups varied in drug resistance were statistically analyzed.Results 38(51.4% ) of the 74 MDR-TB were embB 306-mutant (X2 =93.8,P＜0.01).Of the 24 TB resistant to at least two drugs but not MDR, 9(37.5% ) were embB 306 mutant (X2 =60.1 ,P＜0.01 ).But only two(4.9% ) embB 306-mutant strains were found in 41 strains resistant to only one drug (X2 =6.8,P=0.0093).None embB 306-mutant strains were found in 152 pansensitive strains.The specificity of using embB 306 as a molecular marker for detecting multi-drug resistant TB was 94.9% (206/217).Conclusions As a molecular marker for screening drug resistant TB,especially MDR-TB, the gene locus embB 306 shows a relatively high sensitivity and specificity, promising a sound future for its application in clinics to realize fast screening of patients infected with MDR-TB and to provide evidence for appropriate medication.

Objective To evaluate the effects of seven different skin interventions in the result of penicillin skin test by network Meta-analysis. Methods A systematic search of PubMed, Cochrane Library, Web of Science, EBSCO, Chinese Biomedical Literature Database, China National Knowledge Infrastructure and Wanfang Database from construction to July 2017 was carried out. Control trials examining the effects of skin interventions on the false positive rate of penicillin skin test were included. Methodological quality of included studies was assessed according to the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0.All data was screened,extracted and reviewed by 2 researchers independently and analyzed by WinBUGS, R and Stata. Results Totally 18 trials involving 25 077 patients were included.The results of network Meta-analysis showed the statistically significant difference in favor of saline, 0.5% glutaral and iodine-containing disinfector when compared to alcohol (P<0.05). However,there was no difference in effects between other different skin interventions on the false positive rate (P>0.05). Probability ranking showed that there was a great possibility for saline, direct injection, 0.5% glutaral and iodine-containing disinfector in the reduction of false positive rate. Conclusions Saline, 0.5% glutaral and iodine-containing disinfector were superior to other skin interventions in reducing false positive rate of penicillin skin test.

Objective To explore the association of interleukin (IL)-1 genotypes with Alzheimer′s disease (AD). Methods Using polymerase chain reaction and restriction fragment length polymorphism, the IL-1A (-889) and IL-1B (+3953) genotypes in 84 cases of AD and 139 controls were detected and analyzed. Results The frequencies of IL-1A(- 889) C/C, C/T and T/T genotypes were 72.6% and 84.2%, 23.8% and 14.4%, 3.6% and 1.4% in AD cases and controls respectively. The genotypes frequencies of IL-1A (-889) C/C, C/T and T/T in AD cases were similar to that of controls (χ2=4.53, P＞0.05), but the frequencies of IL-1A (-889) T allele were significantly higher in AD cases than in controls (15.5% vs. 8.6%, χ2=4.93, P＜0.05). The frequencies of IL-1B (+3953) C/T genotypes and T allele were also significantly higher in AD cases than in controls (16.7% vs. 6.5%, 8.3% vs. 3.2%, χ2=5.88,5.56, both P＜0.05). Conclusions IL-1 genotypes are associated with AD. IL-1 genotypes may play an important role in the development of AD.

OBJECTIVETo explore the relationship between central obesity and cardiovascular risk factors and their clustering in adults of Jiangsu province.

METHODSMulti-stratified clustering sampling method was used to sample 8 400 residents aged 18 years and over from 14 diseases surveillance units in Jiangsu province from October to December 2010. Information was obtained with face-to-face interview, physical examination and laboratory testing. A total of 8 380 residents finished the study protocol and their data were analyzed. Central obesity was defined as waist circumference ≥ 85 cm in males or ≥ 80 cm in females. Following complex weighting of the samples, level and proportion of cardiovascular risk factors in group with different waist circumference were analyzed.

RESULTSThe prevalence of central obesity among adults in Jiangsu province was 46.2%, the proportion of males and females was 46.4% and 46.1%, respectively (P > 0.05). The prevalence of center obesity varied significantly in residents with different age, area, education and occupation (all P < 0.01). The level of systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, triglyceride, high density lipoprotein cholesterol and low density lipoprotein cholesterol was also significantly different in residents with different degree of waist circumference (all P < 0.01). The prevalence of hypertension, diabetes, dyslipidemia and clustering of cardiovascular risk factors increased in proportion to increasing waist circumference (all P < 0.05). Multivariate logistic regression analysis showed that the risk of hypertension, diabetes, dyslipidemia and clustering of cardiovascular risk factors was 2.2 (OR = 2.2, 95% CI: 2.0-2.4) and 4.7 (OR = 4.7, 95% CI: 3.9-5.7); 2.1 (OR = 2.1, 95% CI: 1.7-2.5) and 3.8 (OR = 3.8, 95% CI: 3.2-4.5); 2.3 (OR = 2.3, 95% CI: 1.8-2.9) and 4.1 (OR = 4.1, 95% CI: 3.2-5.3); 3.4 (OR = 3.4, 95% CI: 2.9-3.9) and 8.0 (OR = 8.0, 95% CI: 6.2-10.2) fold higher in residents with mild and severe central obesity than residents without central obesity.

CONCLUSIONSThe extent of central obesity positively correlates with the prevalence of cardiovascular risk factors and their clustering in adults of Jiangsu province. Comprehensive interventions on obesity serve as an important tool to reduce the cardiovascular risk in adult Jiangshu residents.
