Objective To summarize present randomized controlled trials ( RCTs) and assess the effect of physical training on vasovagal syncope using meta-analysis method. Methods According to inclusion and exclusion criteria of literature review, articles during 2012 to 2013 were selected from medical electronic databases searching, including Cochrane Library, PubMed, Medline, EMBASE, Elsevier, Ovid, CNKI, and Wanfang by computer. Results Six RCTs were selected finally. According to Meta-analysis of 6 RCTs, it represented that 6 RCTs included totally 250 patients in treatment group and 265 patients in control group, and indicated patients in treatment group ( 252 cases ) having lower rate of syncope recurrence as compared with control group (265 cases) (RR =0. 40, 95%CI; 0. 24 -0. 69,P =0. 000 5). Conclusions The currently published RCTs support that physical training can be effective treatment of vasovagal syncope and further large-scale multicentre and better designed study were still expected to give more convincing evidence.

Objective To explore the relevant protective/risk factors during the development of coronary heart disease blood stasis evidence in the process of pre-existing evidence based on the macro-,meso-,and micro-health state characterization parameter system of Chinese medicine state science.Methods 253 cases of coronary heart disease to be investigated were collected from the outpatient and inpatient departments of the Department of Cardiology in the hospitals affiliated to Hunan University of Traditional Chinese Medicine,and questionnaires were formulated according to the three dimensions of macro,meso,and micro,and the collected parameters were categorized with Python software,and the patients were diagnosed as pre-coronary heart disease blood stasis evidence(150 cases)and coronary heart disease blood stasis evidence(100 cases),and statistical analyses were performed with frequency analysis,χ2 test,and Logistic regression and other methods for statistical analysis.Results ①The results of univariate analysis showed that:age,BMI,history of smoking,history of alcohol consumption,history of hypertension,history of diabetes mellitus,average monthly high temperature,air quality,season,type of occupation,social environment,coronary artery angiographic stenosis,diastolic blood pressure,systolic blood pressure,creatinine,uric acid and total cholesterol differed between patients diagnosed as pre-Coronary artery disease blood stasis evidence and those diagnosed as Coronary artery disease blood stasis evidence,and all the differences were statistically significant(P<0.05).② Binary logistic regression analysis showed that age,BMI,history of alcohol consumption,type of occupation,coronary angiographic stenosis,diastolic blood pressure,creatinine,and dark red tongue were independent risk factors.A prediction model was established:P=1/[1+exp(16.522-1.427×age-0.975×BMI-3.55×drinking history+1.982×monthly average high temperature+0.709×season-1.827×occupational type-1.1×coronary angiographic stenosis-0.072×diastolic blood pressure-0.076×creatinine+2.398×dizziness-4.108×dark red tongue+4.169×pulse asthenia)],the model prediction rate was 90.5%.Conclusion The logistic regression model of coronary heart disease with blood stasis evidence is good with clinical diagnosis,which lays the foundation for the exploration of the state between the already diseased and undiseased of coronary heart disease,and provides important basic data for the theory of subhealth.

Objective To analyze results of breast cancer screenings in the Cancer Screening Program in Urban China (CanSPUC) during 2012-2013. Methods In 14 cities of 9 provinces (Eastern Region: Beijing, Hebei, Liaoning, Shandong and Guangdong; Central Region: Heilongjiang and Hunan;Western Region: Chongqing and Gansu), 198 097 women aged 40-69 years who had lived in their cities for ≥3 years were surveyed through a cancer risk assessment questionnaire during 2012-2013. The questionnaires identified women considered to be at high risk for breast cancer, of whom 17 104 received screening examinations, for whom complete records of breast cancer screening and other data were available for 12 440 subjects altogether, including breast ultrasound exams for subjects 40-44 years old. Subjects older than 45 years or in whom breast imaging reporting and data system (BI-RADS) ultrasound had found≥3 lesions also underwent mammography. In this cohort, BI-RADS 3 class was defined as suspicious and BI-RADS ≥4 class as positive. Chi-square tests were used to compare breast cancer screening results by groups. Results As of October 2013, breast cancer screening percentages for the 12 440 subjects for whom full data were available were, by region, Eastern: 55.43% (6 895); Central: 21.45% (2 669); and Western:23.12% (2 876); by age, 40-44 years: 5.50% (684); ≥45 years: 94.50% (11 756). Using BI-RADS, 2018 subjects were found to have 3 lesions (detection rate:16.22%), which were distributed regionally as Eastern:19.00% (1 310 women), Central: 13.75% (367) and Western; 11.86% (341); χ2=91.45, P<0.001; and 289 were found to have≥4 lesions (detection rate:2.32%), which were distributed regionally as Eastern:2.41%(166), Central:1.54%(41) and Western;2.85%(82);χ2=11.04, P=0.004. Women aged 50-54 years had the highest detection rate of BI-RADS 3 lesions at 18.74% (561/2 994), and those aged 40-44 years had the highest detection rate of BI-RADS ≥4 at 2.92% (20/684). Conclusion Detection rates of BI-RADS ≥4 lesions were highest in the Western region and in women aged 40-44 years, and lowest in the Central region and in women aged 60-64 years. Detection rates of BI-RADS 3 lesions were highest in the Eastern region and in women aged 50-54 years and the lowest in the Western region and in women aged 60-64 years.

OBJECTIVE To study the quality grade stand ard of the premature Forsythia suspensa . METHODS A total of 138 batches of premature F. suspensa were collected from the main producing areas of F. suspensa in China. According to 2020 edition of Chinese Pharmacopoeia ，the contents of impurities ，moisture，ethanol-soluble extract ，volatile oil ，forsythin and forsythoside A in the premature F. suspense were determined ，and the qualified samples were screened. AHP-PCA mixed weighting method was used to give comprehensive weight to the indicators （except for the limit of impurity ）. The comprehensive score of the samples was calculated. The suggestions on the quality grade division of premature F. suspensa were put forward according to cluster analysis of K-mean value. RESULTS & CONCLUSIONS The contents of impurities ，moisture，ethanol-soluble extract ，volatile oil ，forsythin and forsythoside A in the premature F. suspense were 0-7.80％，1.60％-8.18％，13.13％-61.60％，0.21％-3.47％，0.02％-2.15％ and 0.79％-14.04％，respectively；average contents of them were 1.24％，4.97％，34.88％，2.01％，0.42％，6.86％，respectively. Totally 47 batches of 138 batches were qualified in all indexes. It is suggested that the quality grade of the premature F. suspense can be divided into three grades ：in first grade of F. suspense ，the contents of volatile oil ，forsythin，forsythoside A ， ethanol-soluble extract and moisture were ≥2.40％，≥0.59％，≥8.34％，≥38.66％ and ≤4.99％，respectively；in second grade of F. suspense ，the contents of above indicators were ≥2.26％，≥0.41％，≥7.47％，≥32.58％ and ≤5.33％，respectively；in third grade of F. suspense ，the contents of above indicators were ≥2.15％，≥0.32％，≥4.60％，≥31.52％ and≤7.23％，respectively.

Objective·To construct and verify the mouse model that can mimic the vitamin A deficiency(VAD)-like craniofacial skeletal deformity and do not cause embryonic death.Methods·Based on the Cre-LoxP system,the OsxCre;Rosa26dn/dn mice expressing osteoblast-specific dominant-negative retinoid acid receptor α(dnRARα)mutation were obtained by hybridization through OsxCre and Rosa26dnRARa/ddnRARa mice,to achieve the conditional inhibition of retinoic acid signaling to simulate VAD disease.Femur bone mesenchymal stem cells(BMSCs)and parietal bone cells of OsxCre;Rosa26dn/dn mice and their control littermates were isolated and underwent osteogenic induction,to assess the expression of retinoid acid receptor α(RARα)protein through Western blotting.Osteoblasts induced from parietal bone cells of OsxCre;Rosa26dn/dn mice and their control littermates were isolated and the effect of retinoic acid signaling inhibition was verified through dual luciferase gene reporter assay.Meanwhile,Ad-eGFP or Ad-Cre adenovirus-infected femur BMSCs and parietal bone cells of Rosa26dn/dnmice underwent osteogenic induction to assess the expression of dominant-negative mutant protein and the inhibition of the retinoic acid signaling pathway in vitro by Western blotting and dual luciferase gene reporter assay.Moreover,the skulls of 6-week-old OsxCre;Rosa26dn/dn mice were collected,and Micro-CT scanning and three-dimensional(3D)reconstruction were performed to verify the craniofacial skeletal deformities of the mouse model.Results·Western blotting results demonstrated that the level of RARα protein increased in the femur and parietal osteoblasts of OsxCre;Rosa26dn/dn mice compared to that of their control littermates,and also increased in the Ad-Cre-infected femur and parietal osteoblasts of Rosa26dn/dn mice compared to that in the Ad-eGFP-infected group(P＜0.05).Dualluciferase gene reporter assay results indicated that the activity of retinoid acid response element(RARE)was inhibited in the osteoblasts of OsxCre;Rosa26dn/dn mice compared to their control littermates,and was also inhibited in the Ad-Cre-infected group compared to the Ad-eGFP-infected group(P＜0.05).Micro-CT and 3D reconstruction suggested that the skull of 6-week-old OsxCre;Rosa26dn/dn mice exhibited VAD-like craniofacial skeletal deformities,including smaller size of the skull and osteogenesis imperfecta compared to their control littermates.Conclusion·An osteoblast-specific dnRARα expressing mouse model that can mimic VAD-like craniofacial skeletal deformity is successfully constructed,therefore providing a new model for exploring the pathogenesis and therapeutic targets of VAD-like craniofacial skeletal deformity in the future.
