目的 探讨数字减影血管造影（DSA）在冠状动脉病变诊断中的应用价值，并评估血清学参数相对于DSA金标准的诊断效能。方法 本研究纳入100名确诊为冠心病的患者。病例组为100例DSA确诊的冠心病患者，对照组按1:1比例匹配100例同期接受DSA检查排除冠心病的患者。应用DSA技术分别评估冠心病的狭窄程度及部位等指征。回顾性收集并对比分析两组患者的各项血清学参数（cTnI、CK-MB、hs-CRP、LDL-C、TC），计算血清学指标诊断冠心病的效能，并进一步探究以上评估于入组患者性别亚组间的统计学差异。结果 病例组与对照组在性别、年龄、BMI等基线资料上均衡可比（P > 0.05）。以DSA为金标准，cTnI诊断冠心病的灵敏度为82.0%，特异度为85.0%；hs-CRP的灵敏度为85.0%，特异度为75.0%。 cTnI、hs-CRP水平随冠状动脉狭窄程度加重而显著升高（P < 0.05）。且以上冠心病评价指征于患者性别亚组间均无统计学差异（ P <0.05）。结论 DSA技术可用于冠状动脉病变发生的部位、形态、数目等指征的明确评估，且于不同性别亚组间无统计学差异。血清学参数，尤其是cTnI和hs-CRP，对冠心病具有良好的辅助诊断价值，其水平与病变严重程度相关，可作为DSA检查前的有效筛查工具，为后续的治疗提供重要的参考依据。

Objective: To investigate the clinical value of digital subtraction angiography (DSA) in the diagnosis of coronary artery disease (CAD) and to evaluate the diagnostic performance of serological parameters relative to the DSA gold standard. Methods: A total of 100 patients with confirmed CAD were included in this study. The case group comprised 100 patients with CAD confirmed by DSA, while the control group consisted of 100 age- and sex-matched individuals who underwent DSA during the same period and were excluded from CAD. DSA was employed to assess the degree and location of coronary artery stenosis. Retrospective collection and comparative analysis of serological parameters (cTnI, CK-MB, hs-CRP, LDL-C, TC) were performed between the two groups. The diagnostic efficacy of these serological indicators for CAD was calculated, and subgroup analyses were conducted to explore potential sex-related differences. Results: The case and control groups were comparable in baseline characteristics such as sex, age, and BMI (P > 0.05). Using DSA as the gold standard, the sensitivity and specificity of cTnI for diagnosing CAD were 82.0% and 85.0%, respectively; hs-CRP demonstrated a sensitivity of 85.0% and specificity of 75.0%. Levels of cTnI and hs-CRP increased significantly with the severity of coronary stenosis (P < 0.05). No statistically significant differences were observed between male and female subgroups (P > 0.05). Conclusion: DSA provides definitive assessment of lesion location, morphology, and number in coronary artery disease, with no significant sex-related differences. Serological markers, particularly cTnI and hs-CRP, demonstrate good auxiliary diagnostic value for CAD. Their levels correlate with disease severity and may serve as effective screening tools prior to DSA, offering important reference value for subsequent clinical management.

Objective To analyze the distribution of pathogens and the epidemiological characteristics of children with acute lower respiratory tract infections (ALRTI) admitted to Zhengzhou People’s Hospital from February 2024 to February 2026. Methods: A total of 193 pediatric patients with ALRTI who visited Zhengzhou People’s Hospital between February 2024 and February 2026 were selected as study subjects. Throat swab samples were collected from the patients, and pathogen testing results were compiled to compare the distribution of pathogens across different genders, age groups, and seasons of onset. Results: Among the 193 children, 165 tested positive for pathogens, resulting in an overall positive detection rate of 85.49%. The top three most frequently detected pathogens were RSV (20.73%), MP (19.69%), and HRV (15.54%); RSV infection had the highest prevalence (44.83%) among infants, followed by HRV infection (20.69%). Among preschoolers, the prevalence of RSV, HRV, and MP infections (17.31%, 17.31%, and 19.23%, respectively) was relatively high. MP infections were most common among preschool and school-age children (33.33% and 26.32%, respectively); the proportion of mixed infections was lower among infants (6.90%) but higher among preschoolers (20.00%); In spring, the distribution of pathogens was relatively balanced, with high proportions of HRV, MP, and SP infections (14.58%, 12.50%, and 14.58%, respectively). In summer and fall, the MP infection rate was high (31.82% and 28.85%, respectively). In winter, the RSV infection rate (55.10%) was high. The proportion of children with mixed infections was relatively similar across the four seasons, with a relatively higher infection rate (17.31%) in autumn. Conclusion: Among the pathogens identified in children with acute lower respiratory tract infections admitted to Zhengzhou People’s Hospital from 2024 to 2026, RSV and MP were the primary pathogens. The incidence peaks of various respiratory pathogens varied according to the children’s age groups and seasons. Clinicians should conduct early pathogen identification based on actual conditions to guide the development of targeted treatment plans and improve patient outcomes.

【摘要】 目的 探讨基于峰值呼气流速（peak expiratory flow rate，PEFR）的呼吸性肌肉力量减低对I-IIIA期非小细胞肺癌（non-small cell lung cancer，NSCLC）患者术后预后的影响。方法 回顾性分析我院2020年1月-2025年11月接受根治性手术切除的I-IIIA期NSCLC患者临床及影像资料，包括基于肺功能的PEFR（呼吸性肌肉力量指标）及胸部CT的胸肌质量指数（pectoralis muscle index, PMI）。分别采用Jonckheere-Terpstra检验、Spearman’s相关分析比较PEFR与PMI随年龄的变化规律及二者的相关性。低PEFR定义为小于PEFR的性别特异性下四分位数，进一步采用单、多因素Cox回归分析探讨PEFR及PMI对NSCLC患者术后结局的影响。结果 共纳入102例患者，中位年龄62岁（53-67岁），男性65例（63.7%），低低PEFR组24例（23.5%）。低PEFR组在年龄、FEVI、DLCO、FEV1/FVC、FVC、血清白蛋白及随访时间等方面均与正常组间存在显著差异（P＜0.05）。在男、女性患者中，PEFR均表现为随年龄增长逐渐下降的趋势；且与PMI具有较好的相关性（r=0.25，P=0.001）。单因素及多因素Cox回归分析显示，低PEFR是影响NSCLC患者术后无进展生存期（progression free survival, PFS）的独立危险因素（HR=1.57，95%CI：1.03-2.39；P=0.036）结论 呼吸性肌肉力量减低是NSCLC患者术后PFS的独立危险因素，有望成为NSCLC术后复发的早期生物学标志物。

【Abstract】 Objective To investigate the impact of reduced respiratory muscle strength, assessed by peak expiratory flow rate (PEFR), on postoperative outcomes in patients with stage I-IIIA non-small cell lung cancer (NSCLC). Methods Clinical and imaging data of patients with stage I-IIIA NSCLC who underwent radical resection at our hospital from January 2020 to November 2025 were retrospectively analyzed, including PEFR (an indicator of respiratory muscle strength) based on pulmonary function tests and the pectoralis muscle index (PMI) derived from chest CT. The Jonckheere-Terpstra test and Spearman’s correlation analysis were used to evaluate age-related changes in PEFR and PMI and their correlation, respectively. Low PEFR was defined as values below the sex-specific lower quartile of PEFR. Univariate and multivariate Cox regression analyses were performed to assess the impact of PEFR and PMI on postoperative prognosis in NSCLC patients.Results A total of 102 patients were enrolled, with a median age of 62 years (range 53-67 years); 65 patients (63.7%) were male, and 24 (23.5%) were classified into the low PEFR group. The low PEFR group showed significant differences from the normal PEFR group in age, FEV1, DLCO, FEV1/FVC, FVC, serum albumin, and follow-up duration (all P < 0.05). In both male and female patients, PEFR progressively decreased with age and was positively correlated with PMI (r = 0.25, P = 0.001). Univariate and multivariate Cox regression analyses identified low PEFR as an independent risk factor for postoperative progression-free survival (PFS) in NSCLC patients (HR = 1.57, 95% CI: 1.03–2.39; P = 0.036).Conclusion Reduced respiratory muscle strength is an independent risk factor for postoperative PFS in NSCLC patients and may serve as an early biomarker for postoperative recurrence.

Objective To compare the clinical efficacy of phacoemulsification (Phaco) combined with goniosynechialysis and phacoemulsification combined with trabeculectomy in the treatment of acute primary angle-closure glaucoma (APACG) complicated with cataract. Methods The clinical data of 200 patients with APACG complicated with cataract treated in our hospital from January 2022 to January 2025 were retrospectively analyzed. According to surgical procedures, the patients were divided into trabeculectomy group (Phaco combined with trabeculectomy) and goniosynechialysis group (Phaco combined with goniosynechialysis), with 100 patients (200 eyes) in each group. Intraocular pressure, visual acuity [best corrected visual acuity (BCVA)], central anterior chamber depth, optic disc vessel density [whole-image optic disc vessel density (wiVD), disc-inside vessel density (diVD)], quality of life [25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25)] and complications were compared between the two groups. Results At 1 week, 1 month and 3 months after surgery, the goniosynechialysis group had lower intraocular pressure, better BCVA, deeper central anterior chamber depth, and higher wiVD and diVD than the trabeculectomy group (P<0.05). One month postoperatively, the NEI-VFQ-25 score of the goniosynechialysis group was significantly higher than that of the trabeculectomy group (P<0.05), while no significant difference was observed between the two groups at 3 months after surgery (P>0.05). The overall incidence of complications in the goniosynechialysis group was 6.50%, which was lower than 13.00% in the trabeculectomy group (P<0.05). Conclusion Compared with phacoemulsification combined with trabeculectomy, phacoemulsification combined with goniosynechialysis can effectively control intraocular pressure, increase anterior chamber depth, improve optic disc blood circulation, restore visual acuity, enhance quality of life and reduce the incidence of complications in patients with APACG complicated with cataract.

Objective : To investigate the effect of lidocaine combined with esketamine on recovery quality and cognitive function in patients undergoing lung surgery. Methods : A total of 100 patients receiving pulmonary resection at our hospital between July 2023 and December 2025 were enrolled and randomized via a random number table into two equal arms (n=50 per group): observation and control. The control group was treated with routine anesthesia to maintain anesthesia, and the observation group was treated with lidocaine and esketamine on the basis of routine anesthesia. The recovery quality [ Riker sedation agitation score ( SAS ) at 30 min after extubation, recovery time, extubation time ], cognitive function [ simple mental state examination score ( MMSE ) before operation and 1 d, 3 d after operation ], perioperative hemodynamic indexes [ mean arterial pressure ( MAP ), heart rate ( HR ) before anesthesia drug infusion ( T0 ), tracheal intubation ( T1 ), 5 min after extubation ( T2 ) ] and the incidence of adverse reactions at 72 h after operation were compared between the two groups. Results : In the observation group, the SAS score measured 30 minutes post-extubation and the MMSE scores at 1 day and 3 days post-operation were significantly higher than those in the control group. Conversely, both recovery and extubation times were shorter in the observation group compared to the control group. No significant differences in MAP and HR were observed at T0, T1, and T2 within the observation group (P > 0.05). In contrast, within the control group, MAP and HR at T1 and T2 were notably elevated compared to T0, with the differences being statistically significant (P < 0.05). Conclusion : The application of lidocaine combined with esketamine in lung surgery can improve the quality of recovery, protect postoperative cognitive function, maintain perioperative hemodynamic stability, and has good safety.

The sensitivity, specificity, and accuracy of ultrasound were 70.89% (112/158), 86.21% (50/58), and 75.00% (162/216), respectively; while those of SPECT/CT were 92.41% (146/158), 94.83% (55/58), and 93.06% (201/216), respectively. The sensitivity and accuracy of SPECT/CT were significantly higher than those of ultrasound (both?P<0.001). The detection rates of SPECT/CT in the upper-left, lower-left, and upper-right regions were significantly higher than those of ultrasound (P<0.05).?Conclusion?99mTc-MIBI SPECT/CT dual-phase imaging demonstrates superior sensitivity and accuracy compared with cervical ultrasound in preoperative localization of SHPT, especially showing significant advantages in detecting lesions in the upper-left, lower-left, and upper-right regions. It can serve as an important supplement or the first-choice imaging modality for preoperative localization in SHPT patients.
