目的 探讨白蛋白-胆红素（ALBI）联合中性粒细胞与淋巴细胞比值（NLR）预测肝硬化合并食管胃底静脉曲张破裂出血（EGVB）的临床价值。方法 回顾性分析2021年1月—2022年12月肇庆市第一人民医院消化内科收治的80例肝硬化合并EGVB患者的临床资料,通过电话及门诊、再入院对其进行为期1年的随访,根据随访结果,将其分为2组,即存活组（n=69）与死亡组（n=11）,分析导致患者死亡的危险因素,并评估ALBI联合NLR预测肝硬化合并EGVB患者死亡的临床价值。结果 死亡组的年龄60岁以上、腹水和肝性脑病者占比,总胆红素（TBiL）、NLR、凝血酶原时间（PT）、谷丙转氨酶（ALT）水平及ALBI评分均高于存活组（均P<0.05）,而血红蛋白（HGB）、白蛋白（ALB）及血钠水平均低于存活组（均P<0.05）;Logtisic回归分析显示,年龄60岁以上、腹水、肝性脑病和TBiL、NLR水平升高及ALBI分级为3级是肝硬化合并EGVB患者死亡的危险因素（均P<0.05）;ALBI联合NLR预测肝硬化合并EGVB患者预后的准确率及灵敏度高于单一诊断,漏诊率低于单一诊断（P<0.05）。结论 肝硬化合并EGVB患者可见ALBI评分及NLR水平升高,而以上两种指标是患者死亡的危险因素,将其联合检测可评估患者预后,预测其死亡风险。

Objective To investigate the clinical value of albumin-bilirubin（ALBI）combined with neutrophil lymphocyte ratio（NLR）in predicting liver cirrhosis complicated with esophageal and gastric varices bleeding（EGVB）．Methods The clinical data of 80 patients with liver cirrhosis complicated with EGVB admitted to the Department of Gastroenterology of the First People's Hospital of Zhaoqing from January 2021 to December 2022 were retrospectively analyzed．They were followed up for one year by telephone,outpatient service and readmission．According to the follow-up results,they were divided into the survival group（n=69）and the death group（n=11）．The risk factors leading to the death of patients were analyzed and evaluated．Results The proportion of age over 60,ascites and hepatic encephalopathy,the levels of TBiL,NLR,PT,ALT and ALBI in the death group were higher（P<0.05）,while the levels of HGB,ALB and blood sodium were lower（P<0.05）．Logistics analysis showed that age over 60,ascites,hepatic encephalopathy,NLR and ALBI grade 3 were independent risk factors for the death（P<0.05）．The accuracy and sensitivity of ALBI combined with NLR in predicting their prognosis were significantly higher than that of single diagnosis,and the missed diagnosis rate was lower（P<0.05）．Conclusions ALBI scores and NLR levels significantly increase in patients with liver cirrhosis complicated with EGVB,and the above two indexes are risk factors for the death,and the combination of them can evaluate the prognosis of patients and predict the death risk．

自发性脑出血（SICH）是脑卒中的一种常见形式,其预后通常较差,因此早期评估和调节患者出血后的免疫状态至关重要。免疫检查点是评估T淋巴细胞活跃性和增殖状态的关键指标,监测这些检查点有助于预测脑出血患者的预后。程序性死亡蛋白1（PD-1）和细胞分化抗原28（CD28）作为两个典型的免疫检查点,它们在脑出血预后评估中的应用正逐渐成为研究的热点。该文综述了脑出血后机体免疫状态的变化,以及PD-1和CD28在脑出血后评估和治疗中的研究进展。

Spontaneous intracerebral hemorrhage（SICH）is a common cause of stroke,with specific outcomes often being poor．Therefore,early assessment and modulation of the immune status after hemorrhage are of critical importance．Immune checkpoints serve as key indicators for assessing the activation and proliferation of T cells,and monitoring these checkpoints can help to predict the outcomes of patients with intracerebral hemorrhage．PD-1（programmed death 1）and CD28（Cluster of Differentiation 28）are two representative immune checkpoints,and their use in prognostic assessment after intracerebral hemorrhage is becoming a focus of research．This article reviews the changes in the immune state of the body after intracerebral hemorrhage,as well as the research progress on the use of PD-1 and CD28 in the evaluation and treatment following intracerebral hemorrhage．

Objective To explore the therapeutic effects of bronchoalveolar lavage in children with severe pulmonary infection complicated by lung consolidation and its impact on CT features and pulmonary function．Methods A prospective study was conducted on 100 children with severe pulmonary infection complicated with pulmonary consolidation in a hospital from May 2022 to May 2024．They were randomly divided into observation group and control group using a random number table method,50 cases in each group．The control group of children received routine treatment,and the observation group received conventional treatment plus bronchoalveolar lavage．Clinical efficacy,inflammatory factors,CT features,and alterations in pulmonary function before and after therapy were compared．Results The total effective rate of the observation group was higher than that of the control group（P<0.05）．After treatment,the white blood cell count（10.36±2.52）×10⁹/L,interleukin-6（20.57±5.05）ng/L,C-reactive protein（13.12±2.64）mg/L,and procalcitonin（101.62±12.16）pg/L in the observation group were all lower than those in the control group（13.25±3.32）×10⁹/L,interleukin-6（31.69±4.11）ng/L,C-reactive protein（16.16±4.44）mg/L,and procalcitonin（113.46±18.11）pg/L（P<0.05）．After treatment,the proportion of CT imaging features such as pleural effusion,bronchial wall thickening,air bronchogram sign,lung consolidation,ground glass opacities,decreased in both groups of children,and the observation group was lower than the control group（P<0.05）．After treatment,the peak levels of expiratory flow in both groups of children increased,with the observation group（90.67±18.45）L/s higher than the control group（81.27±17.69）L/s．The forced vital capacity levels were also higher,with the observation group（3.33±0.68）L higher than the control group（2.68±0.25）L（P<0.05）．Conclusions Adding bronchoalveolar lavage to routine treatment for children with severe pulmonary infection complicated with pulmonary consolidation can improve their clinical efficacy,alleviate inflammatory reactions,and improve various chest CT manifestations and lung function．

目的 血清同型半胱氨酸（Hcy）水平与慢性肾脏病（CKD）的进展相关,但中年人群的非线性关联研究较少,本研究旨在寻找慢性肾脏病危险因素。方法 本研究基于NHANES 1996—2006年数据,纳入5 361例45~65岁参与者,以估算肾小球滤过率（eGFR）<60 mL/（min·1.73 m²）和尿白蛋白/肌酐比值（uACR）≥30 mg/g评估肾功能下降。结果 通过逻辑回归及平滑曲线拟合分析发现,Hcy每升高1 µmol/L,eGFR降低的风险增加8%（OR=1.08,95%CI：1.06~1.10）,uACR升高的风险增加2%（OR=1.02,95%CI：1.00~1.04）。非线性分析显示,Hcy对eGFR的阈值效应拐点为13.4 µmol/L（拐点左侧OR=1.59,95%CI：1.49~1.70;右侧无显著关联）。亚组分析表明,性别、高血压、糖尿病等协变量无交互作用,然而,在敏感性分析中,糖尿病患者中Hcy与eGFR降低的关联更强（交互P=0.015 8）。结论 本研究提示,控制Hcy水平或可延缓美国中年人群（尤其是糖尿病患者）的肾功能衰退。

Objective Elevated serum homocysteine（Hcy）levels are linked to chronic kidney disease（CKD）progression,yet the nonlinear relationship in middle-aged populations remains underexplored．Methods This study analyzed data from 5 361 participants aged 45-65 years in the NHANES 1996-2006 cohort．Renal dysfunction was defined as an estimated glomerular filtration rate（eGFR）<60 mL/min/1.73 m² and urinary albumin-to-creatinine ratio（uACR）≥30 mg/g．Results Logistic regression and smoothed curve fitting revealed that each 1 µmol/L increase in Hcy elevated the risk of reduced eGFR by 8%（OR=1.08,95% CI：1.06-1.10）and uACR by 2%（OR=1.02,95% CI：1.00-1.04）．A nonlinear threshold effect was identified at 13.4 µmol/L,with a stronger association below this threshold（OR=1.59,95% CI：1.49-1.70）and no significant effect above it．Subgroup analyses showed no interactions with gender or hypertension,but a stronger Hcy-eGFR association was observed in diabetics（interaction P=0.0158）．Conclusions These findings suggest that controlling Hcy levels may mitigate renal decline,particularly in diabetic populations,warranting further causal investigations．

Objective To investigate and analyze the role of magnifying endoscopy in endoscopic submucosal dissection（ESD）in the treatment of early esophageal cancer and precancerous lesions．Methods Esophageal cancer patients in our hospital from January 2020 to July 2022 were selected as the observation objects,the investigator was a first-degree relative over 40 years old who found abnormal esophageal lesions through ordinary endoscopy,and underwent magnifying endoscopy,according to suspected esophageal mucosal epithelial nipple capillary loop（IPCL）changes,defined the nature of the lesion to estimate the invasion depth．Patients with suspected early esophageal cancer and precancerous lesions were given ESD treatment,and those with suspected progressive esophageal cancer underwent surgical treatment,and were sent to the whole specimen for pathological examination．Results A total of 128 patients with first-degree relatives of esophageal cancer over 40 years old were found to have simultaneous enlarged endoscopy simultaneously through common endoscopy,among which 102 patients had obtained overall pathological specimens by ESD and surgery．Comparing the preoperative diagnosis of magnifying gastroscopy and the postoperative overall pathological specimens,the overall accuracy of magnifying endoscopy for the diagnosis of early esophageal lesions was 87.3%,the sensitivity of detecting early esophageal squamous cell carcinoma was 97.8%,specificity was 15.4%,the positive predictive value was 88.8%,and the negative predictive value was 50%．In terms of invasion level,the overall accuracy of magnifying endoscopy for the depth diagnosis of early esophageal squamous cell carcinoma was 69%,90.6% accuracy and 70.6% sensitivity of B1 vessels,32.2% and 76.9% of B2 vessels,66.7% and 33.3% of B3 vessels．Conclusions The magnifying endoscopic treatment of patients with early esophageal cancer and precancerous lesions under ESD can accurately diagnosis the nature of esophageal lesions,improve the detection rate of lesions,and has high practical value．
