Objective:To analyze the factors that influence the height development of children and adolescents aged 3 to 16 years in Chengguan District of Lhasa of Xizang Autonomous Region, China.Methods:During the period from August 2021 to June 2022, a convenient sampling method was used to select 100 children and adolescents aged 3-16 years residing in Chengguan District of Lhasa of Xizang Autonomous Region, China. The subjects' physical measurement indicators, Tanner stage, height development questionnaire, wrist bone age, sex hormones, and nutritional biochemical indicators were carefully collected. The factors that influence height development were analyzed using univariate and multivariate logistic regression analyses. Furthermore, the receiver operating characteristic (ROC) curves were constructed to visualize the effects of these influential factors.Results:The study involved a total of 100 children and adolescents, with 51 (51.0%) participants in the tall stature group and 49 (49.0%) participants in the low stature group. Significant differences were observed between the two groups in terms of height difference relative to the national average, body weight, waist circumference, luteinizing hormone level, the percentage of individuals with an abnormal luteinizing hormone level, follicle stimulating hormone level, and bone age [ χ2 ( t) = 13.6, 2.65, 2.47, -2.58, 10.9, -2.95, 11.8, all P < 0.05]. A univariate logistic regression analysis revealed that body mass, waist circumference, the percentage of individuals with an abnormal luteinizing hormone level, follicle stimulating hormone level, and bone age are factors that possibly affect height development ( OR = 1.05, 1.05, 4.56, 1.18, 2.99, all P < 0.05). Furthermore, a multivariate logistic regression analysis revealed waist circumference, the percentage of individuals with an abnormal luteinizing hormone level, and bone age as independent factors influencing height development ( OR = 1.10, 7.01, 3.14, all P < 0.05). The receiver operating characteristic (ROC) curve analysis showed that the values of the area under the curve were 0.65, 0.65, 0.67, and 0.75 respectively for waist circumference, the percentage of individuals with an abnormal luteinizing hormone level, bone age, and their combination (all P < 0.05). Conclusion:Waist circumference, the percentage of individuals with an abnormal luteinizing hormone level, and bone age appear to be critical factors influencing the height development of children and adolescents In Chengguan District of Lhasa of Xizang Autonomous Region, China.

Objective:To study the methods of hormone-related teaching in standardized residency training of endocrinology.Methods:From February 2022 to June 2022, 25 residents in the Department of Endocrinology, Peking University Third Hospital were given a standardized residency training. The teaching mode combined with a hundred years of insulin development was adopted to practice insulin teaching, and questionnaires were evaluated before and after the teaching. Chi-square test was performed by SPSS 20.0.Results:A total of 31 physicians participated in the training, and 25 residents who were included in the first-stage standardized training were analyzed. Before the training, only 3 people (12%) knew the development history of insulin, and 10 people (40%) answered all the questions about clinical use of insulin correctly. After the training, 23 residents (92%) said they knew or were familiar with the history of insulin development, and 20 residents (80%) answered the questions about the clinical use of insulin correctly, all of which were higher than those before the training, and the difference was statistically significant.Conclusion:The integration of medical history in standardized residency training in endocrinology department can effectively improve the teaching effect, and enhance the humanity quality of young doctors, which can become an effective vehicle in standardized residency training.
