目的 探讨经颅多普勒超声（TCD）参数联合屏气指数在颈内动脉（ICA）狭窄或闭塞所致急性脑梗死的评估价值。方法 选择2022年1月—2024年12月，在广州市花都区人民医院连续入组发病72 h内ICA狭窄或闭塞所致的急性脑梗死患者。记录患者人口统计学资料、临床资料及TCD相关参数，包括搏动指数（PI）、阻力指数（ RI）、大脑中动脉平均血流速度（Vm）及屏气指数等。依据患者数字减影血管造影（DSA）结果分为侧支循环良好组及侧支循环不良组。比较两组人口统计学、临床资料及TCD相关参数，采用单因素分析、多因素Logistic回归分析及ROC曲线。结果 共纳入ICA狭窄或闭塞所致急性脑梗死共136例，其中侧支循环良好组46例，侧支循环不良组90例。单因素分析提示：侧支循环良好组与侧支循环不良组在PI［0.95（0.80，1.03）vs 1.01（0.88，1.13）］、RI［0.58（0.51，0.62）vs 0.60（0.54，0.65）］、Vm［57（44，65）vs 50.5（41，63）］及屏气指数［0.78（0.75，0.85）vs 0.72（0.59，0.79）］方面，差异具有统计学意义（P＜0.05）。多因素Logistic回归分析提示Vm（OR=1.029，95%CI：1.006~1.053，P=0.014）、屏气指数（OR=723.401，95%CI：14.524~3 6031.859，P＜0.001）是侧支循环不良的独立危险因素。屏气指数和Vm评估侧支循环情况的ROC曲线下面积（AUC）分别为0.713（95%CI：0.627~0.799）和0.605（0.505~0.705），两者的AUC值比较差异无统计学意义（P＞0.05）。结论 屏气指数和Vm可以评估ICA狭窄或闭塞所致急性脑梗死的侧支循环，屏气指数和Vm的评估效能相当。
Objective To explore the evaluation value of transcranial Doppler ultrasound（TCD）in acute cerebral infarction caused by internal carotid artery（ICA）stenosis or occlusion．Methods From January 2022 to December 2024，patients with acute cerebral infarction caused by ICA stenosis or occlusion within 72 hours of onset were enrolled in our hospital．Patient’s demographic data，clinical data，and TCD related parameters，including pulsatility index（PI），resistance index（RI），average blood flow velocity（Vm）of the middle cerebral artery，and breath holding index（BHI）were recorded．According to the results of digital silhouette angiography（DSA），patients were divided into good collateral group and poor collateral group．Demographic，clinical data，and TCD related parameters were compared between two groups using univariate analysis，multivariate Logistic regression analysis and ROC curve．Results A total of 136 cases of acute cerebral infarction caused by ICA stenosis or occlusion were included，including 46 cases in the collateral good group and 90 cases in the collateral poor group．Univariate analysis showed that the good collateral group and the poor collateral group were different in PI（0.95［0.80，1.03］vs 1.01［0.88，1.13］），RI（0.58［0.51，0.62］vs 0.60［0.54，0.65］），Vm（57［44，65］vs 50.5［41，63］），BHI（0.78［0.75，0.85］ vs 0.72［0.59，0.79］）（P＜0.05）．Multivariate Logistic regression analysis showed that Vm（OR=1.029，95%CI：1.006-1.053，P=0.014）and BHI（OR=723.401，95%CI：14.524-36 031.859，P＜0.001）were independent risk factors for collateral circulation disorders．The area under the ROC curve（AUC）for predicting collateral circulation using BHI and Vm were 0.713（95%CI：0.627~0.799）and 0.605（0.505~0.705），respectively．There was no statistically significant difference in AUC values between the BHI and Vm．Conclusions The BHI and Vm can predict the collateral circulation of acute cerebral infarction caused by ICA stenosis or occlusion，and their predictive power is comparable．
目的 探讨不同年龄儿童性早熟的影响因素及预防措施。方法 本文将2020年1月—2021年1月的性早熟儿童45例(观察组)与正常健康儿童45例(对照组)作为研究对象,通过问卷调查的形式了解所选儿童的家庭因素、饮食、生活方式与社会因素等方面的情况,通过单因素分析与多因素分析探讨相关影响因素。结果 观察组不同年龄段儿童在骨龄、身高、体质量、BMI方面存在统计学差异,P＜0.05;观察组性激素水平明显高于对照组,P＜0.05。结论 儿童性早熟的发生与生活习惯、家庭关系、饮食习惯、母亲初潮年龄等因素有关,帮助其养成科学合理的生活习惯与饮食习惯,改善家庭关系可很好的降低并预防儿童性早熟的发生。对于已经出现性早熟现象的儿童来说,学校与家庭要及时给予其合理的健康教育,包括心理方面与生殖健康方面,及时有效的疏导可有效避免性早熟对儿童心理方面造成不良影响。
Objective To explore the influencing factors and preventive measures of precocious puberty in children of different ages. Methods 45 cases of precocious puberty children (observation group) and 45 cases of normal healthy children (control group) from January 2020 to January 2021 were selected as the research objects. The family factors, diets, lifestyles and social factors of the selected children were investigated by questionnaire survey, and the related influencing factors were discussed by single factor analysis and multi factor analysis. Results There were statistical differences in bone age, height, weight and BMI among children of different ages in the observation group, P<0.05. The levels of sex hormones in the observation group were higher than those in the control group, P<0.05. Conclusion The occurrence of children's precocious puberty is related to living habits, family relations, eating habits, mother's menarche ages and other factors. To help them develop scientific and reasonable living habits and dietary habits and improve family relations can reduce and prevent the occurrence of children's precocious puberty. For children with precocious puberty, schools and families should give them proper health education in time, including psychological and reproductive health. Timely and effective counseling can effectively avoid the adverse effects of precocious puberty on children's psychology.
