目的 探讨肝硬化腹水患者不同血清钠水平与病情严重程度的关系。 方法 回顾分析2008年7月－2010年6月收治47例肝硬化腹水并发低钠血症患者，根据其入院时血清钠水平分为低钠血症轻（A组）、中（B组）、重（C组）3组。比较肝硬化腹水患者不同血钠水平的腹水程度及疗效的关系、以及低钠程度与肝性脑病、肝肾综合征和死亡发生率的关系。 结果 与A组比较，B、C两组腹水量、肝性脑病、肝肾综合征及病死率明显增高，差异有统计学意义（P＜0.05）；对治疗的效果明显降低（P＜0.05）。 结论 肝硬化腹水患者的血清钠水平与其病情程度具有紧密相关性，监测血清钠的水平可作为判断病情严重程度的重要指标之一，提示在临床上需重视预防、及时发现并治疗低钠血症。
ObjectiveTo explore the association of pretreatment hyponatremia with clinicopathological and prognostic characteristics of non-small cell lung cancer (NSCLC) patients. MethodsThe PubMed, EMbase, Web of Science, VIP, CNKI and WanFang databases were searched from the inception to July 12, 2021 for relevant literatures. The quality of included studies was assessed by the Newcastle-Ottawa Scale (NOS) score. The relative risk (RR) and hazard ratio (HR) with 95% confidence interval (CI) were combined to assess the relationship between pretreatment hyponatremia and clinicopathological and prognostic characteristics. The prognostic indicators included the overall survival (OS) and progression-free survival (PFS). All statistical analysis was conducted by the STATA 15.0 software. ResultsA total of 10 high-quality studies (NOS score≥6 points) involving 10 045 patients were enrolled and all participants were from Asian or European regions. The pooled results demonstrated that male [RR=1.18, 95%CI (1.02, 1.36), P=0.026], non-adenocarcinoma [RR=0.86, 95%CI (0.81, 0.91), P＜0.001] and TNM Ⅲ-Ⅳ stage [RR=1.17, 95%CI (1.12, 1.21), P＜0.001] patients were more likely to experience hyponatremia. Besides, pretreatment hyponatremia was significantly related to worse OS [HR=1.83, 95%CI (1.53, 2.19), P＜0.001] and PFS [HR=1.54, 95%CI (1.02, 2.34), P=0.040]. Pretreatment hyponatremia was a risk factor for poor prognosis of NSCLC patients. ConclusionMale, non-adenocarcinoma and advance stage NSCLC patients are more likely to experience hyponatremia. Meanwhile, the pretreatment sodium level can be applied as one of the prognostic evaluation indicators in NSCLC and patients with hyponatremia are more likely to have poor survival. However, more researches are still needed to verify above findings.
