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．

Objective To explore the ethnic differences in heart structure and function between aborigines and long term residents in the plateau area. Methods A total of 200 aborigines and long term residents who underwent physical examination in our hospital from June 2022 to August 2023 were selected as the study subjects,and the aborigines and long term residents were divided into male and female subgroups,and subgroups aged 18-30 years,31-40 years and 41-50 years．The differences of cardiac structure parameters,left ventricular function parameters and Doppler parameters were compared among subgroups. Results The left atrial diameter,right atrial diameter,right ventricular diameter,pulmonary artery diameter,ascending aorta diameter,aortic root diameter,interventricular septal thickness,left ventricular posterior wall thickness,left ventricular end-diastolic diameter,left ventricular end-systolic diameter,left ventricular ejection fraction mitral valve A peak velocity were compared between Aborigines and plateau Long Term Residents,which were no significant difference（P>0.05）．However,the velocity of aortic valve orifice,pulmonary valve orifice and mitral valve E peak velocity increased,and the differences were statistically significant（P<0.05）．There were no significant differences in left atrial diameter,right atrial diameter,right ventricular diameter,pulmonary artery diameter,ascending aorta diameter,aortic root diameter,interventricular septal thickness,posterior left ventricular wall thickness,left ventricular end-diastolic diameter,left ventricular end-systolic diameter,left ventricular ejection fraction,left ventricular diameter,left ventricular diameter,and left ventricular ejection fraction mitral valve A peak velocity indexes in aborigines and long term residents between among aged 18-30 years,31-40 years,41-50 years（P>0.05）,but the differences of aortic valve orifice velocity,pulmonary valve orifice velocity and mitral valve E peak velocity were statistically significant（P<0.05）. Conclusions There were no significant difference in cardiac structure parameters and left heart function parameters between aborigines and long term residents in plateau area．However,the aortic orifice velocity,pulmonary orifice velocity and mitral E-peak velocity of aborigines were higher than those of long term residents．

目的 探讨依奇珠单抗对中重度斑块型银屑病的治疗效果。方法 选取厦门大学附属第一医院2022年1月—2023年8月收治的75例中重度斑块型银屑病患者,应用抽签法进行分组,分为试验组（n=35）与对照组（n=40）。对照组采取常规外用药物治疗,试验组采取依奇珠单抗治疗。对比两组临床疗效,治疗前后外周血调节性T细胞（Treg）和辅助性T细胞17（Th17/Treg）细胞水平变化,并对所有患者进行6个月门诊复查随访,对比复发率及不良反应。结果 试验组总有效率88.57%,高于对照组的67.50%（χ²=4.730,P=0.028）;治疗后两组患者Treg细胞升高,试验组（5.59±1.24）%高于对照组（4.12±1.13）%,对比差异有统计学意义（t=5.371,P<0.001）,Th17细胞、Th17/Treg细胞降低,试验组[（1.06±0.14）%、0.19±0.05]低于对照组[（1.71±0.28）%、0.42±0.14],对比差异有统计学意义（t=12.434、9.212,P<0.001）;试验组停药后6个月复发率低于对照组（5.71% vs 27.50%,χ²=6.180,P=0.013）;试验组不良反应发生率略高于对照组,组间对比差异无统计学意义（14.29% vs 5.00%,χ²=1.900,P=0.168）。结论 依奇珠单抗治疗中重度斑块型银屑病疗效显著,可调节Th17/Treg平衡,降低停药后复发率,且安全性较高。

Objective To explore the therapeutic effect of Ixekizumab on moderate to severe plaque psoriasis. Methods Seventy-five patients with moderate to severe plaque psoriasis who were admitted to the First Affiliated Hospital of Xiamen University from January 2022 to August 2023 were selected and allocated by lottery into an experimental group（n=35）and a control group（n=40）．The control group received routine external medication while the experimental group received Ixekizumab treatment．The clinical efficacy of two groups,changes in Th17/Treg cell values before and after treatment were compared,and a 6-month outpatient follow-up for all patients was conducted to compare recurrence rates and incidence of adverse reactions. Results The total response rate in the experimental group was 88.57%,which was higher than the 67.50% in the control group（χ²=4.730,P=0.028）．After treatment,the level of Treg cell in the two groups was significantly higher,and the level of Treg cell experimental in the group was higher than that in the control group[（5.59±1.24）% vs （4.12±1.13）%,t=5.371,P<0.001]．After treatment,the level of Th17 and Th17/Treg cell in the two groups were lower,and the level of Th17 cell and Th17/Treg in the experimental group[（1.06±0.14）%,0.19±0.05] were significantly lower than those in the control group[（1.71±0.28）%,0.42±0.14],which was statistically significant（t=12.434、9.212,P<0.001）．The relapse rate at 6 months after drug withdrawal in the experimental group was significantly lower than that in the control group（5.71% vs 27.50,χ²=6.180,P=0.013）．The incidence of adverse reactions in the experimental group was higher than that in the control group,but with no statistical significance（14.29% vs 5.00%,χ²=1.900,P=0.168）. Conclusions Ixekizumab has a significant therapeutic effect on moderate to severe plaque psoriasis．It can regulate the Th17/Treg balance and reduce the recurrence rate after discontinuation,and with high safety．
