Development of a nomogram predictive model for acute mortality risk in patients with type B aortic dissection based on the MIMIC-IV database:A retrospective analysis

:1134-1144
 
       目的   构建并验证主动脉夹层B型(TBAD)患者急性期预后的列线图预测模型,帮助临床医生在急性期内更准确地评估TBAD患者的死亡风险,并制定更合适的治疗策略。方法   回顾性分析从重症监护医学信息数据库v2.2 中提取的399例 TBAD患者的人口学资料和临床资料,结局为TBAD患者急性期(≤14 d)内死亡。先采用最小绝对收缩选择算法回归筛选特征变量,再采用多因素分析确定独立预后因素,并据此构建预测模型。通过受试者工作特征曲线、校准曲线、决策曲线分析(DCA)评价列线图预测模型的性能和临床适用性。结果  APS Ⅲ评分、二氧化碳总量、红细胞分布宽度为TBAD患者14 d内死亡的独立预测因素。列线图预测模型在内部验证中的受试者工作特征曲线下面积为0.776(95% CI0.691 ~ 0.860),Hosmer-Lemeshow 检验P=0.604,校准曲线和标准曲线高度重合,表明该模型具有良好的区分度和校准度。同时,DCA曲线显示,预测模型在大部分的阈值概率范围内提供了显著的净收益。结论   本研究基于APS Ⅲ评分、二氧化碳总量、红细胞分布宽度构建的列线图预测模型可以较准确地预测TBAD患者14 d内的死亡风险,有助于临床医生制定更合适的个体化治疗策略。

帕金森病患者执行功能障碍与脑小血管病总负荷的相关性研究

The total burden of CSVD correlates with the executive functions in patients with Parkinson's disease

:1128-1133
 
        目的   探讨帕金森病(PD)患者执行功能障碍与脑小血管病(CSVD)总负荷的关系。方法   回顾性分析2020年1月1日—2024年6月30日在佛山市第一人民医院住院的156例PD患者收集患者的临床资料,包括性别、年龄、教育年限、高血压病史等,采用简易精神状态量表(MMSE)、蒙特利尔认知评估量表(MoCA)评估认知功能以及采用额叶功能评定表(FAB)评估执行功能。根据患者的认知功能和执行功能评定结果,将156例患者分为PD认知功能正常(PD-NC)组、PD执行功能异常组(PD-EF)和PD非执行功能异常组(PD-NEF)。所有研究对象均行头颅磁共振检查,行CSVD总负荷的评分。比较3组患者一般临床资料、CSVD及其标志物的差异。结果  PD-EF组的年龄、病程、H-Y分期、脑室周围白质高信号(PVWMH)、皮层下白质高信号(DWMH)、腔隙性脑梗死(LI)、CSVD 总负荷评分高于PD-NEF组、PD-NC组,差异均有统计学意义(均P<0.05)。Spearman相关性分析结果显示,PD患者FAB评分与PWMH评分、DWMH评分、LI数目、CSVD总负荷评分均呈负相关(均P<0.05)。多元线性回归分析显示,PD患者FAB评分越低,DWMH评分、LI数目、CSVD总负荷评分均越高(均P<0.05)。结论  PD患者执行功能障碍和CSVD总负荷相关。
       Objective  To explore whether total burden of cerebaral small vessel disease(CSVD)detected with MRI was associated with the executive functions in patients with Parkinson's disease(PD).Methods  In total,156 patients with PD in First People’s Hospital of Foshan from January 2020 to June 2024 were retrospectively enrolled.Detailed clinical data were obtained.The clinical data of all the patients such as age,gender,years of education,hypertension history were collected.The MiniMental State Examination(MMSE)and the Montreal Cognitive Assessment Scale(MoCA)were used to assess cognitive function,the Frontal Assessment Battery(FAB)was used to assess executive function.According to the function levels,all cases were divided into PD with normal cognition(PD-NC)group,PD with executive function(PD-EF)and PD with non-executive function(PD-NEF).All the patients underwent brain MRI to determine the presence and burden of CSVD,scoring between 0 and 4.Results  The age,course of disease,Hoehn-Yahr staging,the scores of periventricular white matter hyperintensities(PWMH),the scores of deep subcortical white matter hyperintensities(DWMH),the numbers of lacunar infarcts(LI),the CSVD scores were significantly higher in the patients of PD-EF group than PD-NC group and PD-NEF group(P<0.05).Spearman’s correlation analysis showed that FAB scores had a significant correlation with scores of PWMH,the scores of DWMH,the numbers of LI,and the CSVD burden scores(P<0.05).Multivariable analysis showed that there was a significant negative correlation between FAB scores and the scores of DWMH,the numbers of LI,the CSVD scores.Conclusions  The total MRI CSVD burden was associated with the executive functions in patients with PD in this study.

埋伏阻生第三磨牙致邻牙牙根外吸收的预后

Prognostic observation of adjacent tooth external root resorption caused by impacted third molars

:1074-1079
 
      目的    分析拔除导致邻牙牙根外吸收(ERR)的埋伏阻生第三磨牙后ERR患牙的预后情况及影响因素。方法   对32例埋伏阻生第三磨牙挤压致ERR的患牙,在拔除阻生第三磨牙后,通过临床症状、电活力测试观察第二磨牙牙髓的预后,根据其预后不同,分为保髓成功组及保髓失败组,比较两组的基本信息(年龄、性别)、患牙部位、牙根吸收类型,分析影响ERR患牙预后的相关因素。结果   下颌ERR患牙保髓成功率(91.67%)高于上颌ERR患牙(62.50%)P=0.085),牙根吸收未及髓腔的患牙保髓成功率(100%)高于牙根吸收及髓腔的患牙(70.59%)(P=0.046),两组间的基本信息比较差异无统计学意义(P>0.05)。结论   当患牙牙根吸收未及牙髓时或患牙位于下颌时,拔除埋伏第三磨牙后ERR患牙预后相对良好,故应尽早拔除已导致ERR发生的埋伏阻生第三磨牙。
       Objective  To analyze the prognosis and influencing factors of external root resorption(ERR)of adjacent teeth after the removal of impacted third molar that caused ERR.Methods  Thirty-two cases of impacted third molars with external root resorption caused by compression were treated.After the extraction of the impacted third molars,the prognosis of the pulp of the second molars was observed through clinical symptoms and electrical activity tests.According to their different prognoses,they were divided into a successful pulp preservation group and a failed pulp preservation group.The basic information(age,gender),affected tooth location,and root resorption type of the two groups were compared,and the relevant factors affecting the prognosis of ERR patients were analyzed.Results  The success rate of pulp preservation for mandibular ERR patients(91.67%)was higher than that for maxillary ERR patients(62.50%)(P=0.085),and the success rate of pulp preservation for ERR not involving pulp cavity(100%)was higher than that for ERR involving pulp cavity(70.59%)(P=0.046).There was no significant difference in basic information between the two groups(P>0.05).Conclusions  When the root resorption of the affected tooth does not reach the pulp or when the affected tooth is located in the lower jaw,the prognosis of the affected tooth after the impacted third molar removed is good.Therefore,the impacted third molar should be removed as soon as possible to prevent ERR from occurring.

单次根管疏通填充对牙体牙髓病患者填充效果、龈沟液 IL-1β、IL-17A、IL-35 水平的影响

Effects of one-time root canal dredging and filling on filling effect and levels of IL-1β,IL-17A and IL- 35 in gingival crevicular fluid in patients with endodontic disease

:1069-1073
 
       目的   探讨单次根管疏通填充对牙体牙髓病患者的填充效果及龈沟液炎症指标的影响。方法   选择2023年8月—2024年2月天津市人民医院接收的牙体牙髓病患者84例进行研究,采用随机数字表法分为两组,各42例。对照组采取多次根管疏通填充,观察组采取单次根管疏通填充,比较2组填充效果、治疗效果、龈沟液炎症指标、口腔健康和功能指标、并发症情况。结果 观察组欠填、恰填、超填比例与对照组比较无统计学意义(χ 2 分别为0.262、1.615、0.512,P别为0.608、0.203、0.474)。观察组的总有效率为97.62%,高于对照组80.95%(χ 2 =6.098,P=0.014)。治疗后,观察组龈沟液白细胞介素IL-1β、IL-17A、IL-35、肿瘤坏死因子-α水平低于对照组(t分别为3.271、3.028、2.699、2.968,P分别为0.002、0.003、0.008、0.004)。治疗后,观察组龈沟出血指数、牙龈指数低于对照组,咬合力、咀嚼效率高于对照组(t分别为2.311、2.686、2.262、2.776,P分别为0.023、0.009、0.026、0.007)。观察组并发症发生率4.76%低于对照组21.43%χ 2 =5.126,P=0.024)。结论   牙体牙髓病采取单次根管疏通填充治疗可保证恰当的填充效果,取得良好的治疗效果,而且减轻龈沟液炎症反应,促进口腔健康和功能改善,并发症较少,安全性高,值得推广。
       Objective  To explore the effects of one-time  root canal dredging and filling on the filling effect and gingival crevicular fluid inflammation indexes in patients with endodontic disease.Methods  A total of 84 cases of endodontic patients admitted to the Tianjin People’s Hospital from August 2023 to February 2024 were chosen and separated into the control group(n=42,multiple-time root canal dredging and filling)and the observation group(n=42,one-time root canal dredging and filling)by random number table method.The filling effect,therapeutic effect,gingival creval fluid inflammation indicators,oral health and function indicators,and complications were compared.Results  The underfilling,accurate filling and overfilling showed no significant difference between the two groups(χ 2 =0.262,1.615,0.512,P=0.608,0.203,0.474).The total effective  rate of observation group was 97.62%,higher than that of control group 80.95%(χ 2 =6.098,P=0.014).After treatment,levels of interleukin(IL)-1β,IL-17A,IL-35 and tumor necrosis factor-α in gingival crevicular fluid of observation group were lower(t=3.271、3.028、2.699、2.968,P=0.002、0.003、0.008、0.004).After treatment,the sulcus bleeding index and gingival index of the observation group were lower,and the biting force and mastication efficiency were higher(t=2.311、2.686、2.262、2.776,P=0.023、0.009、0.026、0.007).The complication rate in the observation group was 4.76%,lower than that in the control group 21.43%χ 2 =5.126,P=0.024).Conclusions  A one-time  root canal dredging and filling treatment for endodontic diseases can ensure proper filling effect,achieve good therapeutic effect,reduce gingival crevicular fluid inflammation,promote oral health and function improvement,with fewer complications,high safety,which is worthy of promotion.
