健康人群血清骨钙素影响因素的研究 —— 以北京市海淀区为例

目的了解健康人群血清OC的变化及与能量代谢的关系。方法根据排除标准筛选115名受试者(男60人,女55人),用电化学发光法和终点法检测血清OC,能量代谢指标水平,并分析血清OC与TC、TG、HDL-C、LDL-C、FINS、FPG、HOMA-IR之间的关系。结果绝经后女性OC水平与男性、绝经前女性差异存在统计学意义(P0.05)。相关性分析中,男、女性年龄与血清OC之间均呈显著负相关(r_男=-0.517和r_女=-0.568)。男、女性BMI与血清OC之间均呈显著负相关(r_男=-0.286和r_女=-0.453)。男性HDL-C与血清OC之间呈显著正相关(rHDL-C=0.271)。女性TG与血清OC之间呈显著负相关(r_(TG)=-0.340);女性HDL-C与血清OC之间呈显著正相关(rHDL-C=0.275)。男性FINS、HOMA-IR与血清OC之间呈显著负相关(r_(FINS)=-0.295,rHOMA-IR=-0.28)。女性FPG、FINS、HOMA-IR与血清OC之间无显著相关性。结论在选取的受试者中,绝经后女性血清OC水平明显低于绝经前女性,绝经后女性出现肥胖较明显。年龄、BMI与血清OC呈显著负相关,即血清OC可能导致肥胖。血清OC与机体能量代谢相关。

目的 调查北京市社区老年人潜在不适当用药(potentially inappropriate medication,PIM)现状.方法 采用自我报告方式,收集北京市社区215名老年人用药信息,根据2019版美国老年人PIM标准(Beers criteria for PIM use in older adults,Beers标准)和中国老年人潜在不适当用药判断标准(中国PIM标准)评价并做描述性分析.结果 根据2019版Beers标准发现66人(30.7%)存在84例次PIM,其中中枢神经系统药物(36例次)、血液系统药物(14例次)、内分泌系统药物(11例次)导致的PIM最多;采用中国PIM标准发现53人(24.7%)存在73例次PIM,前三位分别为:中枢神经系统药物(31例次),血液系统药物(17例次),解热、镇痛、抗炎与抗风湿药(17例次).结论 社区老年人PIM发生率较高,特别是中枢神经系统和血液系统用药需要引起关注.Beers标准和中国PIM标准可相互补充,且需不断更新完善.     

中风病急性期痰热证与MMP-1和MMP-3表达的影响＊

目的 研究缺血性中风病急性期痰热证与MMP-1和MMP-3表达的相关性，其相关性研究能否形成微观辨证的依据。方法 筛选发病7天内就诊于中国中医科学院西苑医院的缺血性中风痰热证患者45名，非痰热证44名，对每例患者分别作出痰湿证、气虚证、血瘀证、内风证、阴虚证和内火证的量化诊断，并用ELISA法检测血清中MMP1和MMP-3的含量。结果 痰热证组和非痰热证组MMP-1和MMP-3的表达均无明显差异。结论 MMP-1和MMP-3不能作为痰热证的微观指标，需进一步寻找微观指标对中风病痰热证证候诊断及疗效评价提供更加客观支持。

The impact of the American College of Surgeons Oncology Group (ACOSOG) Z0011 trial: An institutional review

BackgroundAxillary dissection (AD) was historically recommended for all patients with breast tumor involvement discovered by sentinel lymph node biopsy (+SLNB). However, after the ACOSOG Z0011 trial, omission of AD became the recommendation for selected patients with a +SLNB. We report the impact of ACOSOG Z0011 on the completion AD rate in patients with +SLNB at our institution.MethodsWe retrospectively reviewed all patients diagnosed with breast cancer between March 2009 and February 2013 (n = 1781). This cohort was divided into two groups: 1) those diagnosed BEFORE Z0011 and 2) those diagnosed AFTER Z0011. We calculated both the percentage of patients with a +SNLB who underwent AD and, from those patients, the percentage who did and did not meet the Z0011 criteria.ResultsThe BEFORE group contained 849 patients; 144 had +SLNB and from those 113 underwent AD. The AFTER group contained 932 patients: 139 had +SLNB and from those 73 underwent AD. The completion AD rate in the BEFORE group was 78.5%, compared to 52.5% in the AFTER group (p < 0.001). From the patients who met the Z0011 criteria, 75.6% of the BEFORE patients underwent AD, compared to only 2.2%% in the AFTER group (p < 0.001). Among those who did not meet the Z0011 criteria, a similar percentage of patients underwent AD in each group (BEFORE 79.8%, AFTER 74.4%, p = 0.384).ConclusionFollowing the publication of the ACOSOG Z0011 trial, we experienced a significant decrease in the completion AD rate among patients with a +SLNB who met the Z0011 inclusion criteria.     

Development and validation of a model for the early prediction of the RRT requirement in patients with rhabdomyolysis

IntroductionRhabdomyolysis (RM) is a complex set of clinical syndromes involving the rapid dissolution of skeletal muscles. The early detection of patients who need renal replacement therapy (RRT) is very important and may aid in delivering proper care and optimizing the use of limited resources.MethodsRetrospective analyses of the following three databases were performed: the eICU Collaborative Research Database (eICU-CRD), the Medical Information Mart for Intensive Care III (MIMIC-III) database and electronic medical records from the First Medical Centre of the Chinese People's Liberation Army General Hospital (PLAGH). The data from the eICU-CRD and MIMIC-III datasets were merged to form the derivation cohort. The data collected from the Chinese PLAGH were used for external validation. The factors predictive of the need for RRT were selected using a LASSO regression analysis. A logistic regression was selected as the algorithm. The model was built in Python using the ML library scikit-learn. The accuracy of the model was measured by the area under the receiver operating characteristic curve (AUC). R software was used for the LASSO regression analysis, nomogram, concordance index, calibration, and decision and clinical impact curves.ResultsIn total, 1259 patients with RM (614 patients from eICU-CRD, 324 patients from the MIMIC-III database and 321 patients from the Chinese PLAGH) were eligible for this analysis. The rate of RRT was 15.0% (92/614) in the eICU-CRD database, 17.6% (57/324) in the MIMIC-III database and 5.6% in the Chinese PLAGH (18/321). After the LASSO regression selection, eight variables were included in the RRT prediction model. The AUC of the model in the training dataset was 0.818 (95% CI 0.78–0.87), the AUC in the test dataset was 0.794 (95% CI 0.72–0.86), and the AUC in the Chinese PLAGH dataset (external validation dataset) was 0.820 (95% CI 0.70–0.86).ConclusionsWe developed and validated a model for the early prediction of the RRT requirement among patients with RM based on 8 variables commonly measured during the first 24 h after admission. Predicting the need for RRT could help ensure appropriate treatment and facilitate the optimization of the use of medical resources.     

女性生殖细胞发育过程的分子遗传学研究进展

女性生殖细胞的发育主要经历胚胎发育期和青春期后的卵泡发育期,其中有丝分裂-减数分裂转换、减数分裂阻滞和再激活是发育过程中的关键阶段。各发育阶段独具特征性分子事件,其顺序发生亦需严密的基因调控及与性腺体细胞的交互作用。近年来,单细胞转录组学研究揭示了生殖细胞及性腺体细胞的阶段特异性表达基因、信号传导通路及表观遗传学变化,为深入理解生殖细胞发育过程、阐明相关疾病的发病机制以及促进生殖遗传研究成果的临床转化提供了科学依据和理论基础。
