RESUMO
Objective@#To analyze and compare the correlation between body mass index (BMI) and cardiopulmonary fitness of children and adolescents aged 7 to 18 years in China and Japan, and to provide important reference for healthy development promotion of children and adolescents in China.@*Methods@#A total of 9 594 children and adolescents aged 7-18 years in China and Japan were selected and examined for height, weight and 20 meters shuttle run test (20mSRT), 4 800 of whom were randomly selected and included for analysis. Independent sample t test was used to compare the differences of BMI and 20mSRT between Chinese and Japanese children and adolescents of different sex and age. Logistic regression was used to compare the odds ratio of high cardiopulmonary fitness among children and adolescents of different nutritional status. Pearson correlation and linear regression were used to analyze the correlation between BMI and 20mSRT.@*Results@#Odds ratios of high cardiopulmonary fitness were 0.57, 0.52 and 0.33 in wasting, overweight and obese children and adolescents in China, and 0.49, 0.36 and 0.16 in Japan, respectively, with significant differences(P<0.05). The BMI-Z scores of Chinese and Japanese children and adolescents ranged from - 2.72 to 8.76. There were significant differences in 20mSRT-z between different BMI-Z groups(P<0.05). The 20mSRT-z score of Chinese and Japanese children and adolescents initially increased with BMI-Z score and then decreased with the increase of BMI-z score. With the decrease of BMI-Z score, 20mSRT performance in Chinese boys decreased significantly.@*Conclusion@#Compared with the normal weight peers in China and Japan, the proportion of wasting, overweight and obese children and adolescents with high cardiopulmonary fitness is lower. The BMI-Z score and 20mSRT-z score shows a general inverted "U-shaped" trend. The effect of wasting on cardiopulmonary fitness is greater in Chinese boys.
RESUMO
Objective To explore a best therapy regimen for conservative treatment of ectopic pregnancy.Methods Total of 124 cases of ectopic pregnancy underwent medicine therapy. They were divided into 4 groups: A group with MTX orly,B group with mifepristone only,C group with MTX and mifepristone comblnation,and D group with combined MTX, mifepristone and Traditional Chinese medicine (TCM). Results The curative rate was 80.65% ,61.29% ,87.10% and 90.32% in group A,group B,group C,and group D. The curative rate of group D is higher than other groups (P<0.05, P<0.01 ). Conclusion Combined MTX, mifepfistone and TCM has better effect on ectopic pregnany and has less side effects.
RESUMO
Objective To investigate the clinical characteristics,diagnosis,treatment of endometriosis in adolescent and to improve our knowledge,and to reduce misdiagnosis.Methods Clinical data of 17 patients with endometriosis in adolescents were analyzed retrospectively.Results Preoperative diagnosis is wrong in nine out of 17 cases.All patients underwent surgical operation and post-operative medcine treatment.Five cases have complicated genital tract anomalies.Four cases relapsed,good prognosis is expected in the other patients.Conclusion Clinical characteristics of endometriosis in adolescents are not positive.The treatment involves the surgical operation and medicine.
