RESUMO
With the acceleration of social rhythm， the progress of science and technology， and the increase of the number of phubbers， the incidence of cervical degenerative diseases is also increasing year by year. Cervical spondylotic radiculopathy（CSR）， as one of the diseases induced by cervical degeneration， has seriously affected people's quality of life and physical and mental health. Traditional Chinese medicine（TCM） is effective in the treatment of CSR， but the theoretical and basic experimental evidence is not sufficient， and the current formulation standard of animal model is not unified. Therefore， based on the clinical guidelines of Chinese and Western medicine for CSR and the characteristics of the disease and syndrome， the author systematically summarized and analyzed the existing animal models， and found that the existing models of microvascular clamp nerve root compression method had a poor agreement with the the Chinese and Western medical guidelines， while the modeling methods of spinal canal insertion， autologous bone insertion compression， stainless steel column compression， and fixed frame cervical degeneration reflected a high degree of agreement in the Western medical guidelines. However， the Chinese medical diagnostic criteria were poorly matched. This indicates that the existing animal models of this disease show few TCM syndrome elements， and lack information collection and evaluation in animal behavioral evaluation similar to the four diagnoses of TCM. In conclusion， this paper aims to systematically evaluate the current status of animal model establishment of CSR based on the concept of combination of disease and syndrome， so as to provide a theoretical basis for the model establishment of CSR that is more consistent with clinical characteristics and symptoms of Chinese and Western medicine.
RESUMO
BACKGROUND:Active components of Astragalus have an antioxidant effect, which is considered to result in the neuron-like differentiation of bone marrow mesenchymal stem cels. OBJECTIVE:To investigate the effect of astragalus polysaccharides combined with basic fibroblast growth factor to induce the differentiation of bone marrow mesenchymal stem cels into nerve cels. METHODS:After 24 hours of pretreatment with basic fibroblast growth factor, passage 3 human bone marrow mesenchymal stem cels were cultured with astragalus polysaccharides for 1-3 days (combined group). Blank control group and basic fibroblast growth factor group were set up. Expression of neuron-specific enolase and nestin was detected using western blot or immunocytochemical staining. RESULTS AND CONCLUSION:The expression of neuron-specific enolase was higher in the combined group than the basic fibroblast growth factor group (P < 0.05). Expression of nestin was found in both basic fibroblast growth factor group and combined group, but the gray value was higher in the combined group than the basic fibroblast growth factor group (P < 0.05). These findings indicate that astragalus polysaccharides combined with basic fibroblast growth factor is better to induce the neuronal differentiation of bone marrow mesenchymal stem cels.
RESUMO
Objective:To develop a Child School Refusal Behavior Rating Scale(SRBQC)and examine its reliabilities and validities. Methods:Based on literature review,interview,and open-ended questionnaire,124 origi-nal items were developed. Totally 573 students were recruited to complete the test version. After item and explorato-ry factor analysis,the formal scale-SRBQC was got. Totally 946 students were tested with formal version for further confirmatory factor analysis,internal consistency reliability and composite reliability. The criterion validity was test-ed with the Social Anxiety Scale for Child (SASC). Totally 41 students were retested for test-retest reliability with 2 weeks interval. Results:The formal version of SRBQC included 19 items. Exploratory factor analysis generated 5 factors which account 59. 793% of the variance in all,the results of confirmatory factor analysis showed that SR-BQC had a good construct validity (χ2 =329. 51,df=142,χ2/df=2. 32,CFI=0. 97,GFI=0. 93,IFI=0. 97,NFI=0. 95,NNFI=0. 96,RMSEA=0. 05,SRMR=0. 05). The SRBQC scores were positively correlated with the SASC scores (r=0. 18-0. 34,Ps<0. 05 ). The Cronbach coefficients were 0. 87 for the total questionnaire and 0. 55 -0. 78 for the 5 factors. The test-retest reliabilities were 0. 84 for the total questionnaire and 0. 66 -0. 78 for the 5 factors. Conclusion:The reliability and validity of the School Refusal Bevior Questionaire for Children(SRBQC) meet the needs of psychometrics.
RESUMO
Objectives To explore the relevant factors of liver X receptor (LXR) and lipid metabolism in school-age chil-dren with obesity. Methods A total of 80 obese children were selected by indexes of physical growth from pupils in Grades 1-6, aged 7-14 years from June 2011 to October 2011. Fifty-one age and sex matched children with normal BMI were chosen as nor-mal controls. The metabolic indexes including aspartate transaminase (AST), alanine aminotransferase (ALT), glutamyl transpep-tidase (GGT), total cholesterol (CHOL), triacylglycerol (TG), high density lipoprotein cholesterol (HDL-C), low density lipopro-tein cholesterol (LDL-C) and expression of LXR were detected in fasting blood. Results The expression level of LXR in obese children (9.14 ± 1.15) was higher than that in control children (2.84 ± 3.68) with significant difference (t=4.55,P=0.000). Eighty percent (80%) of obese children were LXR>1 (64/80) which was higher than that of control children (23/51, 45.1%), and signifi-cant difference was found between the two groups (χ2=17.01, P=0.000). Compared to controls, the levels of AST, ALT, GGT, CHOL, TG and LDL-C were higher while the level of HDL-C was lower in obese children (P1 (P<0.05). Conclusions Obesity in school-age chil-dren can up-regulate the expression of liver X receptor and cause liver damage and abnormal lipids metabolism.
RESUMO
Objective To systematically assess the clinical efficacy and safety of apixaban versus enoxaparin in the prevention of venous thromboembolism (VTE) after major orthopedic surgery.Methods Based on the principles and methods of Cochrane systematic review,the Cochrane Library,PubMed,EMBASE,Chinese Bio-medicine Database,China Journal Full-text Database,VIP Database were searched from their establishment to March 2012 in whatever languages.Related journals were handsearched as well.Randomized controlled trials (RCTs) of comparing apixaban and enoxaparin in the prevention of venous thromboembolism after major orthopedic operation were included.Cochrane Collaboration' s tool was used for assessing risk of bias in the included trials.Cochrane Collaboration' s software RevMan 5.1 was used for statistical analysis.Results Four RCTs totaling 12 897 patients were included.Apixaban treatment showed significant differences in aspects of total VTE and all-cause mortality [relative risk (RR) =0.63,95％ CI(0.41,0.96)],major VTE [RR =0.59,95％ CI(0.19,0.98)] and symptomatic deep vein thrombosis (DVT) [RR =0.50,95％ CI(0.26,0.97)] when compared with enoxaparin,but the difference in fatal pulmonary embolism was insignificant[RR =1.57,95％ CI(0.41,5.99)].For patients undergoing total knee arthroplasty,apixaban was associated with significantly fewer major bleeding events[RR =0.55,95％ CI(0.32,0.96)] and fewer total bleeding events[RR =0.79,95％ CI(0.66,0.95)] than enoxaparin.For patients undergoing total hip replacement,however,the two treatments revealed no statistically significant differences.With regard to the incidence of drug-related serious adverse events,the two treatments displayed no significant difference[RR =0.97,95％ CI(0.59,1.58)].Conclusion Apixaban is effective in the prevention of VTE after major orthopedic surgery and can significantly reduce the risk of postoperative VTE.
RESUMO
Objective To evaluate the efifcacy and safety of Xiyanping in the treatment of hand-foot and mouth disease. Methods Based on the principles and methods of Cochrane systematic reviews, Cochrane Library, PubMed, Medline, Chinese Bio-medicine Database (CBM), China Journal Full-text Database (CNKI), VIP database and Wanfang database were searched. All of the randomized controlled trials (RCT) of Xiyanping versus ribavirin were included. The data were extracted and evalu-ated by two reviewers independently. Risk assessment tool was used to assess the risk of bias and software Revman5.0 was used for meta-analysis. Results Twenty-four RCT and 3314 patients were included. Comparing to ribavirin, Xiyanping showed better therapeutic outcomes regarding to total effective rate, durations of fever and rash elimination (RR=1.17, 95%CI:1.12~1.23;MD=-1.56, 95%CI:-2.10~-1.02;MD=-1.41, 95%CI:-1.90~-0.93). Side effects were rare in both groups and could be recovered after drug withdrawal. Conclusions The current evidence suggests that Xiyanping is superior to ribavirin in the treatment of hand-foot and mouth disease.
