Objective To explore the characteristics and risk factors of myopia among adolescents in Yuexiu District,Guangzhou,and to provide reference for reducing the incidence of myopia among adolescents．Methods This project adopted stratified random cluster sampling to select 2 774 adolescents distributed in Yuexu District,Guangzhou as the research objects,which were divided into myopia group（n=1 657）and non-myopia group（n=1 117）according to the myopic examination．Through questionnaire survey,the overall situation and epidemiological characteristics of myopia among adolescents in our district were comprehensively known,in order to explore the related behaviors and factors affecting the occurrence and development of myopia among adolescents in our district,explore reasonable intervention measures,and put forward scientific and effective myopia prevention and control technical means and strategies．Results Among 2 774 adolescents,1 657 were nearsighted（59.73%）．Among them,872 were female and 785 were male．The number of myopia in kindergarten,primary school,middle school and high school students were 20,446,484 and 707 respectively,showing an increasing trend．School period,eyes use environment in school and outside school,reading and writing posture,situations of electronic screen use,close distance eye use,outdoor activities and sleep,myopia examination and correction were the relevant influencing factors on myopia of adolescents in Yuexui District of Guangzhou（P<0.05）．The myopia degree of adolescents in Yuexiu District of Guangzhou was positively correlated with school period,out-of-school eyes use environment,electronic screen use,outdoor activities and sleep conditions,and close distance eyes use（P<0.05）,and negatively correlated with in-school eyes use environment,reading and writing posture,myopia examination and correction conditions（P<0.05）．After Logistic multivariate analysis of the factors with statistical difference between different prognostic groups,school period,eyes use environment in school and outside school,reading and writing posture,electronic screen use,close distance eyes use,outdoor activities and sleep conditions,myopia examination and correction were the relevant influencing factors on myopia of adolescents in Yuexui District of Guangzhou（P<0.05）．Conclusions In Yuexiu District,Guangzhou,the population with myopia is gradually moving to a younger age．School period,eyes use environment in school and outside school,reading and writing posture,electronic screen use,close distance eyes use,outdoor activities and sleep condition,myopia examination and correction are the relevant influencing factors．It is recommended to strengthen the organization of students to go outdoors for a variety of outdoor sports activities between classes,while encouraging parents to set a good example of eye care outside the school and work with the school to protect their children’s eyesight．

目的 探讨Nolla分期对青少年拔牙正畸患者下颌第三磨牙倾斜角的影响。方法 选择2018年10月—2022年10月收治的100例拔牙正畸青少年患者。100例患者均拔除了4颗前磨牙,共有100颗下颌第三磨牙,通过Nolla分期,可将100例患者分成四组,每组25例。Ⅰ组：牙冠正在形成,Ⅱ组：牙冠基本形成,Ⅲ组：牙根形成在1/2以下,Ⅳ组：牙根形成在1/2以上。在治疗前后,测量下颌第三磨牙倾斜角,对角度α的变化进行分析。结果 第三磨牙牙胚倾斜角、MP-SN、MP-FH在不同组间比较差异无统计学意义（F=0.256,P=0.857;F=0.033,P=0.992;F=0.028,P=0.994）;治疗前组间下颌第三磨牙角度比较差异无统计学意义（P>0.05）,治疗后不同组间下颌第三磨牙角比较差异有统计学意义（F=13.376,P<0.001）,治疗前后Ⅰ组、Ⅱ组、Ⅳ组第三磨牙的角度无差异（t=0.757,P=0.453;t=0.224,P=0.824;t=0.852,P=0.399）,Ⅲ组治疗后角度变化减少（t=3.697,P<0.001）。结论 青少年正畸拔牙后,下颌第三磨牙处于牙根形成阶段的一半以下可能会导致第三磨牙近中倾斜加重。当下颌第三磨牙处于牙冠形成阶段,牙冠形成超过一半时,第三磨牙角度变化较小。在治疗前应根据Nolla分期评估下颌第三磨牙的预后情况,并及时制定相应的干预策略。

Objective To explore the effect of Nolla staging on the inclination angle of mandibular third molars in adolescent orthodontic patients undergoing tooth extraction. Methods A total of 100 adolescent patients who underwent tooth extraction orthodontic treatment from October 2018 to October 2022 were included．All 100 patients had 4 premolars extracted,with a total of 100 mandibular third molars．According to Nolla staging,the 100 patients can be divided into 4 groups,with 25 cases in each group．Group I：The crown was forming,Group II：The crown was basically formed,Group III：The root formation was below 1/2,Group IV：The root formation was above 1/2．The inclination angle of the mandibular third molar was measured before and after treatment,and the angle α changes will be analyzed. Results There was no difference in the inclination angle,MP-SN,and MP-FH of the third molar tooth germ among different groups（F=0.256,P=0.857;F=0.033,P=0.992;F=0.028,P=0.994）．There was no difference in the angle of mandibular third molar teeth between groups before treatment（P>0.05）,the contrast of mandibular third molar angles between different groups after treatment was signifiant（F=13.376,P<0.001）,while the angles in Group I,Group and Group Ⅳ were not slgnificantly different（t=0.757,P=0.453;t=0.224,P=0.824;t=0.852,P=0.399）,and the angle change decreased after treatment in Group Ⅲ（t=3.697,P<0.001）. Conclusions After orthodontic extraction in adolescents,if the mandibular third molar is less than half of the root formation stage,it may lead to increased mesial inclination of the third molar．However,when the mandibular third molar is in the stage of crown formation and the crown is more than half formed,the angle change of the third molar is relatively small．Therefore,in clinical practice,Nolla staging should be evaluated in the prognosis of mandibular third molars before treatment and develop corresponding intervention strategies in a timely manner．

目的 探讨青春期多囊卵巢综合征(PCOS)患者血清抗苗勒管激素(AMH)与25(OH)D₃水平的相关性。方法 本研究选择在2019年1月—2020年12月在我院妇科门诊就诊的PCOS青春期女性79名,另选择同期体检的非PCOS健康对照85名。对所有受试者测量身高、体质量,计算体质量指数(BMI)。由诊治医生检查研究对象是否有痤疮、多毛以及月经情况。抽取静脉血检测黄体生成素、卵泡刺激素、总睾酮、硫酸脱氢表雄酮、抗苗勒管激素和 25(OH)D₃,将 25(OH)D₃分为不足[25(OH)D₃<30 ng/mL]和缺乏[25(OH)D₃<20 ng/mL]2组,对数据进行比较分析。结果 与健康对照组比较,PCOS组更容易发生月经稀发/闭经,其痤疮发生率较高(P值均<0.05)。体质量指数、AMH值、总睾酮和硫酸脱氢表雄酮的体内检出水平在PCOS组较高,而25(OH)D₃在PCOS组较低(P值均<0.05)。PCOS组的AMH与BMI和总睾酮呈正相关关系,与25(OH)D₃呈负相关关系(P值均<0.05)。25(OH)D₃缺乏组的AMH水平高于25(OH)D₃不足组,对照组和PCOS组的25(OH)D₃缺乏组的AMH水平均高于25(OH)D₃不足组,两两比较其差异有统计学意义(P值均<0.05)。健康对照组的25(OH)D₃缺乏率为67.1%(57/85),而PCOS组的25(OH)D₃缺乏率为96.2%(76/79),2组比较其差异有统计学意义(χ²=22.68,P<0.001)。结论 青春期多囊卵巢综合征患者体内 25(OH)D₃水平与AMH 水平显著相关。AMH 和25(OH)D₃可用于评估青春期PCOS发病风险的替代指标。

Objective To explore the correlation between serum anti-Müllerian hormone (AMH) and 25(OH)D₃ levels in adolescent patients with polycystic ovary syndrome (PCOS). Methods Seventy-nine adolescent girls with PCOS and 85 non-PCOS healthy controls who walked in the gynecological clinic of our hospital from January 2019 to December 2020 were selected. Height, weight were measured and body mass index (BMI) was calculated.Hirsutism, acne and menstruation were evaluated by doctors on all subjects. Venous blood was drawn to detect levels of luteinizing hormone, follicle stimulating hormone, total testosterone, dehydroepiandrosterone sulfate, AMH and 25(OH)D₃, 25(OH)D₃ was further divided into insufficient [25(OH)D₃<30 ng/mL] and deficient [25(OH)D₃<20 ng/mL]level, then all data were compared and analyzed between two groups. Results Compared with the healthy control group, the PCOS group was more prone to have oligomenorrhea or amenorrhea, the incidence of acne was higher in PCOS group than in control group (all P values<0.05). BMI, the levels of AMH, total testosterone and dehydroepiandrosterone sulfate were significantly higher in the PCOS group compared to the control group, while 25(OH)D₃ was the opposite (all P values <0.05). AMH in the PCOS group was positively correlated with BMI and level of total testosterone, and negatively correlated with 25(OH)D₃ (all P values<0.05). The AMH level in the 25(OH)D₃ deficiency group was higher than that in the 25(OH)D₃ insufficient group, the AMH levels of the 25(OH)D₃ deficient group and control group were higher than that in the 25(OH)D₃ insufficient group,the differences were statistically significant (P<0.05). The 25(OH)D₃ deficiency rate in the healthy control group was 67.1% (57/85), while the 25(OH)D₃ deficiency rate in the PCOS group was 96.2% (76/79). The difference between the two groups was statistically significant (χ²=22.68, P<0.001). Conclusions Serum 25(OH)D₃ level was an independent factor significantly associated with AMH level in adolescents with PCOS. AMH and 25(OH)D₃ levels may be used as surrogate markers of PCOS risk in adolescents.
