原发性高血压伴左心室肥厚患者常规治疗效果的影响因素分析

目的探讨原发性高血压(EH)伴左心室肥厚(LVH)患者常规治疗效果的影响因素。方法选取2018年1月—2020年1月在河北北方学院附属第一医院接受厄贝沙坦治疗的400例EH伴LVH患者为研究对象,根据治疗效果将其分为有效组(359例)、无效组(41例),比较两组患者一般资料、治疗前间歇性左束支传导阻滞(LBBB)发生率及心率变异性(HRV)指标,采用多因素Logistics回归分析EH伴LVH患者治疗效果不佳的影响因素。结果治疗后,有显效、有效、无效患者分别为269例、90例、41例,有效率为89.75%。两组患者性别及入院时极低频、低频(LF)/高频(HF)比较,差异无统计学意义(P>0.05);两组患者年龄、高血压病程、入院时血压、入院时LVH、入院时间歇性LBBB发生率,以及入院时正常RR间期标准差(SDNN)、相邻RR间期之差的均方根(RMSSD)、相邻RR间期差值>50 ms的RR间期所占百分数、HF、LF比较,差异有统计学意义(P<0.05)。多因素Logistic回归分析结果显示:年龄≥65岁、高血压病程≥10年、入院时舒张压较高、收缩压较高、入院时LVH重度肥大、入院时发生间歇性LBBB,以及入院时SDNN、RMSSD、HF、LF是EH伴LVH患者常规治疗无效的危险因素(P<0.05)。结论EH伴LVH患者常规治疗效果受多种因素影响,其中合并间歇性LBBB、HRV降低与EH伴LVH患者常规治疗后疗效不佳有关。

Primary malignant melanoma of the esophagus combined with squamous cell carcinoma:A case report

BACKGROUND Primary malignant melanoma of the esophagus is a rare malignant tumor of the esophagus,and its combination with squamous cell carcinoma is also rare.Here,we report the diagnosis and treatment of a case of primary esophageal malignant melanoma combined with squamous cell carcinoma.CASE SUMMARY A middle-aged man underwent gastroscopy for dysphagia.Gastroscopy revealed multiple bulging esophageal lesions,and after pathologic and immunohistochemical analyses,the patient was finally diagnosed with"malignant melanoma with squamous cell carcinoma".This patient received comprehensive treatment.After one year of follow-up,the patient was in good condition,and the esophageal lesions seen on gastroscopy were controlled,but unfortunately,liver metastasis occurred.CONCLUSION When multiple esophageal lesions are present,the possibility of multiple pathological sources should be considered.This patient was diagnosed with primary esophageal malignant melanoma combined with squamous cell carcinoma.
