RESUMO
Objective:To study the safety and feasibility of gasless transoral endoscopic thyroidectomy though vestibular approach using self-retaining retractor for papillary thyroid carcinoma.Methods:The clinical data of 39 papillary thyroid carcinoma patients undergoing gasless transoral endoscopic thyroidectomy were collected at Department of Head and Neck Surgery, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from Nov 2020 to Jun 2021.Results:All cases successfully underwent laparoscopic surgery without conversion to open surgery. The mean duration of operation was (142±35) min, and the postoperative mean hospital stay was (4.1±0.8) days. The mean maximum diameter of the tumor was (8.5±4.5) mm, and the mean number of lymph node harvest of by central compartment dissection was 7.7±5.9. Postoperative complications were transient hypoparathyroidism in 2 cases but recovered in 1 month. Scalp hydrop in 1 patient,fading subsequently. Transient sensory change around the lower lip in 3 cases, which recovered in 6 months. No patient suffered from recurrent laryngeal nerve palsy or hematoma, no permanent hypoparathyroidism occurred, nor of the postoperative bleeding .Conclusion:The gasless transoral endoscopic thyroidectomy viaoral vestibular approach is a feasible approach in selected papillary thyroid carcinoma patients.
RESUMO
Objective:To investigate the development trend of physical examination volume and revenue in health-checkup institutions in China from 2010 to 2019.Methods:In this longitudinal study, the annual income, annual physical examination volume and other indicators reflecting institutional size were collected with questionnaire from 374 health-checkup institutions in the year of 2010, 2015 and 2019. The geometric mean method is used to calculate the compound annual growth rate (CAGR) of the annual physical examination volume, annual income, mean per capita cost from 2010 to 2015 and 2015 to 2019.Results:The annual physical examination volume of health-checkup institutions increased from 1.81 (1.00, 3.20) ×10 4 person times in 2010 to 5.08(3.50, 7.28)×10 4 person times in 2019; the CAGR of the physical examination volume from 2010 to 2015 was 14.04%(8.14%, 23.78%), and it was 9.49%(3.39%, 19.07%) from 2015 to 2019. The annual revenue increased from 768.73 (350.00, 1 623.75) ×10 4 yuan in 2010 to 3 500.00 (1 997.73, 6 818.54) ×10 4 yuan in 2019; the CAGR of annual revenue from 2010 to 2015 was 25.75% (15.17%, 35.09%), and it was 15.67% (8.78%, 26.11%) from 2015 to 2019. The mean per capita cost increased from 434.26 (278.82, 666.66) yuan in 2010 to 755.80 (506.90, 1 005.42) yuan in 2019; the CAGR of the mean per capita cost was 9.82% (1.71%, 17.10%) from 2010 to 2015, and it was 5.37% (0.95%, 10.46%) from 2015 to 2019. Conclusion:From 2010 to 2019, health-checkup institutions in China developed rapidly, and the CAGR of the annual physical examination volume, annual revenue, mean per capita cost are high.
RESUMO
Objective:To explore the influence of elastic band aerobics training on cardiovascular risk factors in adults.Methods:Twenty-four health management centers participated in the competition. Each individual participant learned elastic band aerobics through video and tested their own indexes before and after intervention. Height, body weight (BW), muscle content (MC), fat content (FC), waist circumference (WC), hip circumference (HC), body fat rate (BFR), resting systolic and diastolic blood pressure (SBP and DBP) were measured. A paired samples t-test was used to analyze pre-and post-test results.Results:After 8 weeks of elastic band aerobics training, there were significant differences in body weight, body mass index (BMI), waist circumference, body fat content, systolic and diastolic blood pressure for male contestants before and after training ( P<0.01). These decreased by 1.39%, 1.45%, 0.98%, 3.61%, 2.28%, 2.34%, and 3.05% respectively. Weight, waist circumference, hip circumference, waist hip ratio, body fat content and rate of female contestants decreased by 1.25%, 1.59%, 0.65%, 0.99%, 4.22%, and 2.38% respectively ( P<0.01). There were significant differences in absenteeism between the top 10 and bottom 14 teams ( P<0.05). Average absenteeism rates were 2.8% and 10.7% respectively. Overall attendance rate of participants was 92.6%, higher than the clinical standard of an 80% level of compliance. Conclusions:Eight-week elastic band aerobics training can significantly improve body composition of adults, reducing body fat rate and waist circumference. Using competition as an opportunity to exercise promotes implementation and persistence of sports training programs.
RESUMO
Objective To learn the development of Chinese health management centers,and to provide evidence for discipline planning and development goals.Methods A self-designed questionnaire was used to get the information about the size and personnel structure,discipline and scientific research,academic and talent training,informatization and comprehensive service ability of 103 health management centers.Results About 76％ health management centers occupied a land of more than 1000 square meters.Annual health checkup showed an increasing trend year by year (from 39 500 persons per year in 2009 to 52 500 persons per year in 2011).Nearly 54％ health management centers provided health/disease risk assessment services,and only 21％ provided psychological evaluation services.The main challenges for academic activities in these centers were information collection and record,research topic selection and study design,specific training for chorin disease screening and technique skills.Conclusion Sustainable development of health management industry in China may largely depend on discipline construction of health management.
RESUMO
Objective To develop a multidimensional self-report health measurement scale for accurate evaluation of health status in Chinese adults. Methods Delphi method was used to select health measurements. Item database was set up based on available questionnaires. A total of 1858 individuals from Beijing, Hebei ,Tianjin, Shanxi and other provinces of China received field pretest. Results A self-report health assessment tool with 90 items was developed, Cronbach a coefficient of which was 0. 669 to 0. 917,split-half reliability 0. 572 to 0. 877, and test-retest reliability 0. 693 to 0. 896. Six factors from exploratory factor analysis accounted for 71.732% total variance,with the common factor＞0.4. Confirmatory factor analysis showed good fit index and construct validity. Conclusion The newly developed self-rated health measurement scale ,which involves six dimensions and 90 items ,shows good reliability and validity.
RESUMO
RNA dot blot hybridization was employed to investigate the alterations in C-myc, C-H-ras transcript levels in bone marrow and peripheral blood cells from 24 patients with acute nonlymphocytic leukemia. 10 cases of normal bone marrow cells were used as control. We found that the positive rates and intensities of expression of C-myc and C-H-ras in acute nonlymphocytic leukemia were hipher than those of normal control. The C-myc and C-H-ras expressed simultaneously in 10 patients. After having been cultured 5 days with RA and low dose Ara-C combined with low dose Harr, the C-myc transcipt level of C-myc in acute nonlymphocytic leukemia was decreased obviously.
