目的 构建首发脑出血患者并发卒中相关性肺炎的风险预测模型并验证模型的预测性能。方法 回顾性分析2012年1月—2022年12月广州市第一人民医院治的419例首发脑出血患者的临床资料，按照7︰3比例随机化分为训练列（293例）和验证队列（126例）。统计基于开发队列数据，采用Logistic回归模型分析首发脑出血患者并发卒中相关性肺炎的影响因素，并构建风险预测模型。基于开发队列和验证队列数据，采用校准曲线、受试者操作特征（ROC）曲线下面积和决策曲线分析模型的预测性能。结果 419例首发脑出血患者中有113例发生卒中相关性肺炎，发生率为26.97%。美国国立卫生研究院卒中量表（NIHSS）评分、吞咽困难、初始血肿体积、中性粒细胞百分比与白蛋白比值（NPAR）、中性粒细胞计数与淋巴细胞计数比值（NLR）、手术治疗、气管插管、留置胃管均是首发脑出血患者并发卒中相关性肺炎的影响因素（P＜0.05）。基于上述影响因素构建了首发脑出血患者并发卒中相关性肺炎的风险预警模型，校准曲线显示模型在开发队列和验证队列中预测卒中相关性肺炎发生率均与实际发生率相近；ROC曲线显示此模型在开发队列、验证队列中预测的曲线下面积分别为0.906（95%CI：0.867~0.937）、0.884（95%CI：0.815~0.934）；决策曲线分析显示当开发队列阈概率在3%~80%内、验证队列阈概率在2%~76%内使用此模型干预比全/无干预更有临床价值。结论 基于NIHSS评分、吞咽困难、初始血肿体积、NPAR、NLR、手术治疗、气管插管、留置胃管构建的首发脑出血患者并发卒中相关性肺炎的风险预测模型具有良好预测性能和临床应用价值。

      Objective To construct a risk prediction model for stroke associated pneumonia in patients with initial cerebral hemorrhage（ICH）and validate the predictive performance of the model．Methods A retrospective analysis was conducted on the clinical data of 419 patients with ICH admitted to our hospital from January 2012 to December 2022．They were randomly divided into a development cohort（293 cases）and a validation cohort（126 cases）according to a 7∶3 ratio．The Logistic regression model was used to analyze the influencing factors of stroke related pneumonia in patients with ICH based on the development cohort data，and a risk prediction model was constructed．Based on the development cohort data and validation cohort data，the predictive performance of the model was analyzed using calibration curves，receiver operating characteristic（ROC）curve，and decision curve analysis．Results Among 419 patients，113 developed stroke associated pneumonia，with a rate of 26.97%．The National Institutes of Health Stroke Scale（NIHSS）score，swallowing difficulties，initial hematoma volume，neutrophil percentage to albumin ratio（NPAR），neutrophil count to lymphocyte count ratio（NLR），surgical treatment，endotracheal intubation，and indwelling gastric tube were all independent influencing factors for stroke associated pneumonia in patients with ICH（P＜0.05）．Based on the above influencing factors，a risk prediction model for stroke associated pneumonia in patients with ICH was constructed．The calibration curve showed that the predicted incidence of stroke associated pneumonia by the model in both the development and validation cohorts was close to the actual incidence．The ROC curve showed that the predicted area under the curve for this model in the development cohort and validation cohort was 0.906（95%CI：0.867-0.937）and 0.884（95%CI：0.815-0.934），respectively．The decision curve analysis showed that when the threshold probability of the development cohort was between 3%-80%，and the threshold probability of the validation cohort was between 2%-76%，the intervention using this model was more clinically valuable than all/no intervention．

Conclusions The risk prediction model for stroke associated pneumonia in patients with ICH based on NIHSS score，swallowing difficulties，initial hematoma volume，NPAR，NLR，surgical treatment，tracheal intubation，and indwelling gastric tube has good predictive performance and clinical application value．

目的 分析围绝经期女性糖脂代谢水平与卵巢储备功能减退（DOR）的相关性，并探讨绝经激素治疗的应用价值。方法 回顾性选取2024年2月至2026年2月就诊于本院的194例围绝经期女性为研究对象，根据其卵巢储备功能将其分为DOR组（n=103）与卵巢储备功能正常组（NOR，n=91）。比较2组临床资料，采用Logistic回归分析围绝经期女性DOR的危险因素，绘制ROC曲线分析其预测效能，并利用Spearman相关系数分析指标相关性。同时予以所有患者绝经激素治疗（MHT），比较治疗前后的性激素指标、糖代谢指标、超声指标及安全性指标。结果 Logistic多因素结果显示：年龄、FSH、HbA1c、TG是围绝经期女性DOR的重要影响因素（P＜0.05）。ROC结果显示：联合预测的AUC=0.982，95%CI为0.964~1.000，灵敏度为0.990，特异度为0.923，校准曲线拟合性好。卵巢储备功能与年龄、FSH、HbA1c、TG均呈显著正相关（P均<0.05）。与治疗前相比，FSH、LH、HbA1c、TG、LDL-C水平有明显下降（P＜0.05），子宫内膜厚度略有增加（P＜0.05）；AMH、卵巢体积无显著变化（P＞0.05）。MHT治疗后不良反应发生率为4.64%。结论 糖脂代谢异常与围绝经期女性DOR密切相关，是其重要危险因素。规范MHT干预可有效改善内分泌代谢紊乱，且安全性可靠。

Objective To analyze the correlation between glycolipid metabolism levels and diminished ovarian reserve (DOR) in perimenopausal women, and to explore the application value of menopausal hormone therapy.Methods A total of 194 perimenopausal women admitted to our hospital from February 2024 to February 2026 were retrospectively enrolled. They were divided into the DOR group (n=103) and the normal ovarian reserve (NOR) group (n=91) according to ovarian reserve function. Clinical data were compared between the two groups. Logistic regression analysis was used to identify risk factors for DOR. Receiver operating characteristic (ROC) curves were plotted to evaluate predictive efficacy, and Spearman correlation analysis was performed to assess indicator correlations. All patients received menopausal hormone therapy (MHT). Sex hormone indicators, glycolipid metabolic indicators, ultrasonographic indicators and safety indicators were compared before and after treatment.Results Multivariate Logistic regression showed that age, folliclestimulating hormone (FSH), glycated hemoglobin A1c (HbA1c) and triglyceride (TG) were independent risk factors for DOR in perimenopausal women (P＜0.05). ROC analysis revealed that the combined prediction yielded an AUC of 0.982 (95%CI: 0.964–1.000), with a sensitivity of 0.990 and a specificity of 0.923, and good calibration curve fitting. Ovarian reserve was significantly positively correlated with age, FSH, HbA1c and TG (all P＜0.05). After treatment, levels of FSH, luteinizing hormone (LH), HbA1c, TG and lowdensity lipoproteincholesterol (LDLC) decreased significantly (P＜0.05), and endometrial thickness increased slightly (P＜0.05). No significant changes were observed in antiMüllerian hormone (AMH) and ovarian volume (P＞0.05). The incidence of adverse reactions after MHT was 4.64%.Conclusion Abnormal glycolipid metabolism is closely associated with DOR and serves as a critical risk factor in perimenopausal women. Standardized MHT can effectively improve endocrinemetabolic disorders with satisfactory safety.

目的 评估调脂药物靶点所介导的脂质表型（HMGCR、PCSK9和NPC1L1）与高血压肾病风险之间潜在的因果相关性。方法 使用来自欧洲人群公开可获得的全基因组关联研究（GWAS）汇总数据进行孟德尔随机化（MR）分析。采用与低密度脂蛋白胆固醇（LDL-C）相关的遗传变异,根据选定的调脂药物靶基因筛选工具变量,使用逆方差加权法作为主要MR分析方法,并进行敏感性分析确保结果的稳健性。结果 基因预测的LDL-C水平与较高的高血压肾病风险相关（OR=1.19,95% CI：1.03~1.38,P=0.021）。较高的HMGCR介导的LDL-C水平与高血压肾病风险存在正向因果相关性（OR=4.08,95% CI：2.86~5.81;P<0.001）。然而,PCSK9和NPC1L1介导的LDL-C水平与高血压肾病风险无相关性。Cochran Q检验、MR-PRESSO检测和MR-Egger截距测试显示工具变量之间不存在异质性或水平多效性。结论 HMGCR介导的LDL-C与高血压肾病的发病风险存在因果相关性,针对HMGCR基因的他汀类药物在高血压肾病的防治中可能具有潜在益处。

Objective To assess the potential causal relationship between lipid phenotypes mediated by lipid-lowering drug targets（HMGCR,PCSK9 and NPC1L1）and the risk of hypertensive nephropathy．Methods Mendelian randomization（MR）analysis was conducted using summary data from publicly available European ancestry genome-wide association studies（GWAS）．Genetic variants associated with low-density lipoprotein cholesterol（LDL-C）were used as instrumental variables based on selected lipid-lowering drug target genes screening tools．Inverse variance weighting was selected as the main MR analysis method,with sensitivity analyses conducted to ensure the robustness of the results．Results Genetically predicted LDL-C levels were associated with a higher risk of hypertensive nephropathy（OR=1.19,95% CI：1.03~1.38,P=0.021）．Higher LDL-C levels mediated by HMGCR were positively causally related to increased risk of hypertensive nephropathy（OR=4.08,95% CI：2.86~5.81;P<0.001）．However,LDL-C levels mediated by PCSK9 and NPC1L1 showed no significant association with the risk of hypertensive nephropathy．Cochran’s Q test,MR-PRESSO,and MR-Egger intercept tests showed no heterogeneity or horizontal pleiotropy among instrumental variables．Conclusions The findings of this study support the causal relationship between LDL-C mediated by HMGCR and increased risk of hypertensive nephropathy,suggesting potential benefits of statin therapy for hypertensive nephropathy．
