目的调查儿童一岁半时视屏内容类型及屏幕暴露频率与学龄前期多动行为的关联，并探究户外活动与视屏行为的交互作用对关联关系的影响，为儿童行为问题的预防及干预提供理论依据及可行方案。方法2022年6月至2023年6月，在广东省惠州市惠城区使用分层整群抽样的方法抽取61所幼儿园中5 648名儿童的家长及教师进行调查，采用Conners教师评定量表（TRS）评估儿童的多动行为，使用自编问卷调查儿童的基本信息、一岁半时视屏内容类型、屏幕暴露频率及户外活动频率。使用多元Logistic回归进行统计分析，在控制儿童的年龄、性别、父母亲受教育程度等因素的条件下，探究视屏行为与多动行为的关联及其与户外活动的交互作用。结果儿童学龄前期多动行为总体检出率为3.2%，品行问题为2.1%、多动问题为2.1%、注意力不集中-被动问题为1.3%、多动指数为0.9%。校正混杂因素后，多元Logistic回归分析显示儿童一岁半时屏幕暴露为“每周2~4次”与学龄前期多动行为的检出率升高有关，比值比（OR） ［95%置信区间（CI）］为1.682 （1.141， 2.480）。每天均有屏幕暴露与学龄前期多动行为、品行问题、多动问题、注意力不集中-被动问题和多动指数的检出率升高均存在关联，OR （95% CI）分别为2.136 （1.218， 3.746）、2.321 （1.185， 4.546）、2.300 （1.208， 4.380）、2.776 （1.267， 6.085）和3.640 （1.525， 8.687），但这种关联在一岁半时每天进行户外活动的儿童中并未发现（交互作用P值＜0.001）。未发现视屏内容类型与多动行为的关联（P＞0.05）。结论幼儿期屏幕暴露频率与学龄前期多动行为问题显著相关，户外活动可以削弱高频屏幕暴露与多动行为之间的关联关系，提示家长及学校应重视对幼儿视屏行为和户外活动的科学引导，合理安排幼儿一日生活，为儿童行为健康发展奠定良好基础。

目的本研究探讨老年慢性心力衰竭（CHF）患者发生低三碘甲状腺原氨酸综合征（LTS）的临床特点及可能的危险因素，建立预测LTS的列线图模型。方法回顾性分析老年CHF患者291例，根据患者入院后检测的甲状腺功能，将其分为LTS组107例和非LTS组184例。收集所有研究对象的一般信息资料和生化指标，同时对可能引起LTS的危险因素中的数值变量（除年龄）均采用中位数进行分组。采用卡方检验对各变量进行统计分析，多因素回归模型分析老年CHF患者合并 LTS的独立危险因素并建立列线图模型。采用C指数、校准曲线及受试者工作特征（ROC）曲线对预测模型进行评估。结果血肌酐（Scr）、C-反应蛋白（CRP）、白介素-6（IL-6）及纽约心脏病协会（NYHA）心功能分级与LTS发生呈正相关（OR 值分别为1.893、2.356、1.021、1.815， P ＜ 0.05），而血清白蛋白（Alb）与LTS呈负相关（OR = 0.412， P ＜ 0.05），即血清Alb水平越低，LTS越容易发生，将上述具有统计学意义的变量引入列线图后，其C指数为0.807［95% CI = （0.757，0.856）］；内部验证的校准曲线表明此预测模型的校准度良好；ROC 曲线分析显示此预测模型的区分度良好。结论老年CHF患者血清Scr、CRP、IL-6、Alb及心功能分级可能是LTS发病的危险因素；血清Alb可能是LTS发病的保护因素。基于以上多种危险因素构建的预测老年CHF患者发生LTS的列线图模型，具有较好的区分度和准确度，可为临床个体化防治提供指导。

目的探索女方体质指数（BMI）对不明原因原发不孕女性人工授精诱导排卵周期（OI-IUI）妊娠结局的影响。方法回顾性分析2016年1月至2022年12月于中山大学孙逸仙纪念医院生殖中心行OI-IUI助孕的不明原因原发不孕夫妻共764个周期的临床资料。按照女方患者BMI分为 3 组，低BMI组（消瘦，BMI＜18.5 kg/m2）、正常BMI组（正常体质量，18.5 kg/m2≤BMI＜23.0 kg/m2）、高BMI组（超重、肥胖，BMI≥23.0 kg/m2 ），比较各组间一般资料以及妊娠结局。采用单因素分析和Logistic回归分析矫正混杂因素，探讨BMI与OI-IUI活产率的相关性。结果三组HCG阳性率（7.08%、9.74%、13.19%）、宫内妊娠率（5.51%、7.91%、13.19%）和活产率（4.72%、6.90%、12.50%）由低BMI组到高BMI组依次递增，早期流产率（14.28%、10.26%、5.26%）则是由低BMI组至高BMI组依次递减，其中高BMI组活产率明显高于低BMI组及正常BMI组，差异有统计学意义（P=0.034）。根据二元Logistic回归分析显示，BMI是影响活产的独立影响因素，与低BMI相比，高BMI可提高活产率（OR=3.15，95%CI=1.191， 8.329，P=0.021）。结论低BMI不利于不明原因原发不孕女性OI-IUI妊娠结局，对该部分患者鼓励以健康方式进行合理增重。

目的探索孤独症谱系障碍 （ASD） 儿童日常执行功能与其核心症状及注意缺陷多动 （ADHD）症状的关联，以及心理理论等其他认知能力对关联的调节作用。方法招募6~12岁ASD儿童，并根据纳入排除标准确定了86名儿童。采用儿童韦氏智力测试 （WISC-Ⅳ）、新异故事测试 （SST）、执行功能行为评定量表 （BRIEF） 评估儿童的认知能力；注意缺陷多动障碍评定量表 （SNAP-Ⅳ）、社交反应量表 （SRS）、重复刻板行为检查表-修订版 （RBS-R） 分别评估儿童的注意缺陷多动症状、社交障碍及重复刻板行为的严重程度。统计方法使用多元线性回归，在控制新异故事分数、言语理解智商等因素的条件下，探索日常执行功能与注意缺陷多动症状、社交损害、重复刻板行为的关联。结果控制新异故事分数、言语理解指数 （VCI） 及其他因素后，ASD儿童的BRIEF总分及各指数与SNAP总分 （b = 0.619~ 0.741，b’ = 0.637~ 0.755）、SRS总分 （b = 0.928~ 1.200，b’ = 0.417~ 0.513） 及RBS-R总分 （b = 0.326~ 0.525，b’ = 0.339~ 0.520） 均存在明显的正向关联 （P< 0.05），并且与SNAP总分的关联更强 （b’ = 0.637~ 0.755，P< 0.01）。除了日常执行功能，新异故事分数 （b = -2.218~ -1.839） 和年龄 （b = 3.181~ 4.037） 也是影响ASD儿童社交功能的重要因素 （P< 0.01）。未发现新异故事分数、年龄对BRIEF分数与SNAP总分、SRS总分及RBS-R总分的关联存在调节效应 （P> 0.05）。结论学龄期ASD儿童的日常执行功能缺陷与ASD症状、ADHD症状显著相关，关联独立于其他领域的认知能力，如心理理论、言语理解智商。

目的 基于机器学习算法对急性缺血性卒中（acute ischemic stroke，AIS）或TIA患者行rt-PA静脉溶栓治疗住院期间脑出血的发生情况进行预测，并探索影响rt-PA溶栓治疗后脑出血发生的危险因素。 方法 纳入中国卒中中心联盟（Chinese Stroke Center Alliance，CSCA）2016年1月—2020年12月登记的被初步诊断为AIS或TIA且接受rt-PA静脉溶栓治疗的患者74 654例，平均年龄为（65.55±12.14）岁，其中，男性患者48 493例（64.96%），住院期间发生脑出血患者2038例（2.73%）。将数据按年份划分为训练集和测试集，即2016—2019年登记患者划分为训练集，2020年登记患者划分为测试集，采用原型选择下采样技术对训练集数据正负样本进行77∶100平衡处理，构建了逻辑回归、极致梯度提升（extreme gradient boosting，XGBoost）、随机森林、梯度提升决策树（gradient boosting decision tree，GBDT）和分类梯度提升（categorical boosting，CatBoost）共5个模型对脑出血结局进行预测，并使用AUC、灵敏度、特异度、Brier评分等指标对模型预测效果进行评价和比较，采用SHAP图对机器学习模型筛选出的特征进行可解释性分析。 结果 XGBoost、GBDT、CatBoost、逻辑回归和随机森林模型的AUC值分别为0.770（95%CI 0.745～0.774）、0.766（95%CI 0.753～0.786）、0.765（95%CI 0.752～0.766）、0.758（95%CI 0.747～0.761）和0.757（95%CI 0.739～0.759），灵敏度分别为0.624（95%CI 0.574～0.672）、0.606（95%CI 0.555～0.655）、0.570（95%CI 0.519～0.620）、0.557（95%CI 0.506～0.607）和0.585（95%CI 0.534～0.635），特异度分别为0.780（95%CI 0.773～0.786）、0.785（95%CI 0.778～0.791）、0.790（95%CI 0.783～0.796）、0.805（95%CI 0.799～0.811）和0.769（95%CI 0.762～0.776），Brier评分分别为0.157、0.154、0.156、0.160和0.161分。通过SHAP图解释结果发现，住院NIHSS评分高、年龄大、空腹血糖水平高、既往心房颤动病史、血小板计数低、发病距溶栓治疗时间窗长、BMI低、就诊时NIHSS评分高等特征为rt-PA溶栓治疗住院期间发生脑出血的危险因素。 结论 基于机器学习构建的预测模型对行rt-PA静脉溶栓治疗的AIS患者住院期间脑出血的发生具有一定预测效果，本研究对未来机器学习技术在脑出血预测领域的应用有一定探索价值。 Abstract: Objective To predict the incidence of cerebral hemorrhage in patients with acute ischemic stroke (AIS) or TIA undergoing intravenous thrombolytic therapy with rt-PA based on machine learning algorithm, and explore the risk factors affecting the incidence of cerebral hemorrhage after rt-PA thrombolytic therapy. Methods A total of 74 654 patients who were initially diagnosed as AIS or TIA and received rt-PA intravenous thrombolytic therapy were enrolled in the Chinese Stroke Center Alliance (CSCA) from January 2016 to December 2020, with an average age of (65.55±12.14) years. Among them, 48 493 were male patients, accounting for 64.96%, and 2038 were cerebral hemorrhage patients during hospitalization, accounting for 2.73%. The data is divided into training sets and test sets by year, that is, the registered patients in 2016—2019 are divided into training sets, and the registered patients in 2020 are divided into test sets. The positive and negative samples of the training set data are 77∶100 balanced using the prototype selection down-sampling technology, and the logistic regression, extreme gradient boosting (XGBoost), random forest, gradient boosting decision tree (GBDT) and categorical boosting (CatBoost) are five models to predict the outcome of intracerebral hemorrhage, and use AUC, sensitivity, specificity, Brier score and other indicators to evaluate and compare the prediction effect of the model, and use SHAP chart to analyze the interpretability of the features screened by the machine learning model. Results The AUC values of XGBoost, GBDT, CatBoost, logistic regression and random forest were 0.770 (95%CI 0.745-0.774), 0.766 (95%CI 0.753-0.786), 0.765 (95%CI 0.752-0.766), 0.758 (95%CI 0.747-0.761) and 0.757 (95%CI 0.739-0.759) respectively, the sensitivity was 0.624 (95%CI 0.574-0.672), 0.606 (95%CI 0.555-0.655), 0.570 (95%CI 0.519-0.620), 0.557 (95%CI 0.506-0.607) and 0.585 (95%CI 0.534-0.635) respectively, the specificity was 0.780 (95%CI 0.773-0.786), 0.785 (95%CI 0.778-0.791), 0.790 (95%CI 0.783-0.796), 0.805 (95%CI 0.799-0.811) and 0.769 (95%CI 0.762-0.776) respectively, and the Brier score was 0.157, 0.154, 0.156, 0.160 and 0.161 respectively. Through the SHAP diagram, we found that the characteristics of high NIHSS score, old age, high fasting blood glucose level, history of atrial fibrillation, low platelet count, long time window between onset and thrombolytic therapy, low BMI, and high NIHSS score at the time of visit were risk factors affecting the incidence of cerebral hemorrhage during the hospitalization of rt-PA thrombolytic therapy. Conclusions The prediction model based on machine learning can predict the occurrence of intracerebral hemorrhage in AIS patients undergoing rt-PA thrombolytic therapy during hospitalization. This study has certain exploration value for the application of machine learning technology in the field of intracerebral hemorrhage prediction in the future.

Angiostrongylus cantonensis (A. cantonensis) has a complex life history and a variety of hosts, and is highly infectious and pathogenic, which poses a serious health threat. The invasion of exotic molluscs has become an important way for A. cantonensis to spread. More and more studies have been conducted on the infection of A. cantonensis by invasive mollusks, and the detection technology of A. cantonensis in the host has been improved gradually. However, the literatures on the infection of A. cantonensis with invasive mollusks are still scattered, there is still a lack of systematic analysis on the susceptibility characteristics and detection techniques of invasive mollusks infected with A. cantonensis. Therefore, the research on invasive mollusks infected by A. cantonensis in the last 20 years was reviewed, and the research progress on infection types, susceptibility, physiological response, genetic profile, host response and detection methods of A. cantonensis infection in invasive mollusks was systematically analyzed. At least 15 species of globally invasive mollusks that are susceptible to A. cantonensis have been reported so far. The larvae (L1-L3) could be parasitized by Pomacea canaliculata, Pomacea maculata/insularum, Achatina fulica, Cipangopaludina chinensis, and Corbicula fluminea. Nitrogen metabolism and oxidative metabolism of infected mollusks were enhanced after infection. The susceptibility of invasive mollusks to A. cantonensis was related to host species, developmental period, breeding environment, infection dose and infection duration. The morphological and molecular methods was often used to detect A. cantonensis. The accuracy of molecular detection method is higher than that of the morphological method. Angiostrongylus cantonensis can spread globally by hitchhiking on invasive mollusks. Simultaneously elucidated the dispersal mechanism of invasive mollusks and the parasitic behaviors of A. cantonensis can provide a useful reference for the prevention, control and management of A. cantonensis.

Pesticide residue pollution in farmland soil is a key factor affecting the safe production of agricultural products. Microbial degradation is a resourceful, efficient, environmentally friendly, and convenient pesticide residue degradation technology. However, it is not significant effective in the practical field application due to its susceptibility to environmental factors. Therefore, stabilizing and enhancing the field activity of degrading bacteria has become a bottleneck in the industrialization of pesticide residue biodegradation technology. Biofilm is a complex community structure formed by bacteria through the secretion of polysaccharides and proteins and other extracellular polymers, which can surround themselves and adhere to the solid surface. Microorganisms exist in the form of biofilms in soil due to the multi-phase and dispersed characteristics of soil environment. The biofilms plays a positive role in enhancing bacteria's resistance to complex environmental stress, improving the degradation ability of pesticide residues, and maintaining soil health. It overcomes the shortcomings of the traditional free-living bacteria direct-injection remediation technology, such as low efficiency, short persistence period, and insensitivity to low concentration pesticide residues. In recent years, research on bacterial biofilms has been applied to bioremediation of water and soil pollution with significant success. On this basis, this article systematically expounds on the degradation mechanism of bacteria biofilm for pesticide residues in soil, analyzes the advantages and ways of using active bacterial biofilms to promote the soil remediation efficiency of pesticide residue pollutions, and proposes innovative research ideas based on bacterial biofilms to enhance soil resistance to pesticide stress and promote soil health. This article provides reference for improving the environment of the production areas of agricultural products and improving the quality and safety of agricultural products. [ABSTRACT FROM AUTHOR]
