目的   通过生物信息学手段筛选非小细胞肺癌（NSCLC）中的关键靶点基因，识别预后标志物NDC80，并探讨其在NSCLC中的表达意义，进而分析NDC80作为NSCLC基因治疗靶点的可行性。方法   采用癌症基因组图谱（TCGA）TCGA数据库检索NSCLC相关数据，进行加权基因共表达网络分析（WGCNA）以识别关键基因，并进行差异表达分析、相关性分析和蛋白互作网络构建。对筛选出的关键基因进行功能分析。利用免疫组化染色法检测癌组织及癌旁组织中NDC80蛋白的表达水平，并进一步探究其与临床病理特征的关系。采用Kaplan-Meier法分析NDC80表达与NSCLC患者无进展生存时间（PFS）的关系。结果   共筛选出20个与NSCLC高度关联的关键基因，包括CDC20、CDK1、MCM4、CDC6、MCM2、PLK1、NDC80、CCNB1、CDC45、AURKA、MCM8、BUB1、CDT1、ORC1、CCNA2、CASC5、MAD2L1、BUB1B、CENPA、AURKB。免疫组化验证显示，NDC80蛋白在NSCLC组织中高表达，其在NSCLC组（阳性表达率88.6%）显著高于癌旁组（50.0%）（P＜0.05）。NDC80蛋白的阳性表达率在TNM分期（Ⅲ期+Ⅳ期）、低分化、淋巴结转移的NSCLC组高于TNM分期（Ⅰ期+Ⅱ期）、高分化及中分化以及未发生淋巴结转移的NSCLC组（P＜0.05）。NDC80蛋白的阳性表达率在不同性别、年龄、病灶大小分类的NSCLC组织中无显著差异（P＞0.05）。Kaplan-Meier分析显示，NDC80蛋白高表达组的PFS中位数为（9.00±0.27）个月，明显低于低表达组（11.00±0.79）个月（P＜0.05）。结论   本研究发现的关键基因在NSCLC干细胞的维持中发挥重要作用。免疫组化结果显示，NDC80蛋白在NSCLC组织中高表达，且与肿瘤分化、TNM分期及淋巴结转移密切相关。NDC80蛋白高表达组的PFS明显低于低表达组，提示NDC80可能成为NSCLC筛查、治疗和预后评估的潜在生物标志物。

        目的   分析广州番禺地区鹦鹉热衣原体肺炎患者临床表现、实验室及胸部CT特征、并发症以及治疗方案，为其临床诊治提供参考。方法   回顾性分析2022年1月—2024年7月在广州市番禺区何贤纪念医院通过二代测序技术确诊的10例鹦鹉热感染患者的临床资料。结果  5例（5/10）患者有明确的鸟类或禽类接触史，8例（8/10）患者以发热为首发症状，发热（10/10）、咳嗽、咳痰（10/10）、呼吸困难（7/10）、相对缓脉（8/10）是主要临床表现。患者白细胞计数通常正常或轻微升高；多数患者存在有不同程度的电解质紊乱（10/10）及肝功能损伤（8/10）、乳酸脱氢酶升高（8/10），白蛋白显著降低（8/10）和C反应蛋白显著升高（10/10）。最常见的胸部CT异常为多肺叶受累的斑片状或片状实变，而重症患者多合并双侧胸腔积液。大多数患者经四环素或喹诺酮类单用，或者四环素联用β-内酰胺类抗菌药物治疗，预后良好。结论   有鸟类或禽类接触史、以发热为首发或主要症状、存在相对缓脉、白细胞计数升高不明显等临床特征可有助于区分鹦鹉热衣原体肺炎与其他传统细菌性肺炎，但这并不能确诊。二代测序技术是确诊鹦鹉热衣原体感染的很好方法，可以缩短诊断延误时间并改善患者预后。

Objective To refine and optimize the paper-based assessment tool for evaluating neurological function in spinal cord injury patients, and to explore its impact on clinical practice．Methods A comprehensive review of existing literature on neuromotor function assessment in spinal cord injury patients was conducted, complemented by discussions among members of this study．This led to the integration of a preliminary evaluation framework．Subsequently, a two-round Delphi consensus process involving experts was undertaken to finalize the content of the assessment project．Based on this, a paper-based evaluation system was developed and converted into an electronic format by computer professionals．This system was then tested in a clinical setting, where it was administered to 120 spinal cord injury patients at the Spine Surgery Department of Guangzhou First People’s Hospital between 1 August 2021 and 31 May 2023．Patients were randomly assigned to either an experimental group or a control group, allowing for a comparison of accuracy, efficiency, and convenience in clinical application．Results The experimental group demonstrated a notable improvement in assessment accuracy over the control group, with a significant reduction in error rate from 20.3% to 4.7% and a decrease in omission rate from 32.0% to 5.0%．Furthermore, the average assessment time was shortened by 6.0 minutes, markedly enhancing the efficiency of the evaluation process．Conclusions The optimized neurological function assessment system for spinal cord injury patients has proven effective in enhancing both the accuracy and efficiency of assessments, while significantly minimizing subjective errors．This system holds considerable potential for widespread clinical adoption and application．

Objective To analyze the clinical study of stellate ganglion block combined with Ginkgo biloba extract to treat cervical dizziness．Methods A total of 100 hospitalized patients with cervical dizziness at Zhoukou Orthopedic Hospital were selected as the study subjects,who were admitted between June 2022 and June 2023．They were divided into a control group and an observation group based on the odd and even numbers of admission,with 50 cases in each group．The control group received stellate ganglion block treatment,while the observation group received a combination of Ginkgo biloba extract treatment on the basis of the control group,The degree of improvement in clinical symptoms（headache,dizziness,tinnitus,blurred vision）,neck pain scale,clinical efficacy,and incidence of adverse reactions were compared between two groups of patients．Results After 30 days of treatment,the clinical symptom score of the observation group was lower than that of the control group（P<0.05）．There was no statistically significant difference in the numerical grading scores between the two groups before treatment（P>0.05）．On the 15th and 30th day of treatment,the observation group had lower numerical grading scores than the control group（P<0.05）．The total effective rate of treatment in the observation group was higher than that in the control group（P<0.05）．During the treatment period,the incidence of complications in the observation group was lower than that in the control group,and the difference was statistically significant（P<0.05）．Conclusions The use of stellate ganglion block combined with Ginkgo biloba extract in the treatment of patients with cervicogenic dizziness can significantly improve their disease symptoms,significantly alleviate their neck pain,effectively improve the clinical effect,while reducing the incidence of adverse reactions．

新生儿期的免疫系统发育阶段对维持新生儿健康至关重要,具有独特的免疫调节机制。近年来,人们越来越关注髓源性抑制细胞（MDSCs）在新生儿免疫调节中的作用。MDSCs是一类免疫抑制功能强大的异质性细胞群体,它们能够通过多种机制调节免疫应答。MDSCs在新生儿中的调节作用对防止过度免疫反应和促进免疫耐受至关重要,有助于预防新生儿期炎症性疾病,并对其后续健康产生积极影响。近期研究文献分析展示了MDSCs在新生儿免疫调节中的多种作用机制,包括在特定病理条件下的保护作用、与新生儿期炎症反应的相互作用,以及对长期免疫发展的潜在影响。因此,深入理解MDSCs在新生儿免疫中的角色,不仅有助于揭示其复杂的调节机制,也为制定新的预防和治疗新生儿炎症性疾病的策略提供了新的思路。

The developmental stage of the immune system during the neonatal period is crucial for maintaining neonatal health,characterized by unique immunoregulatory mechanisms．In recent years,increasing attention has been drawn to the role of myeloid-derived suppressor cells（MDSCs）in neonatal immune regulation．MDSCs represents a heterogeneous population of cells with potent immunosuppressive functions,capable of modulating immune responses through various mechanisms．The regulatory role of MDSCs in neonates is vital for preventing excessive immune reactions and promoting immune tolerance,thereby aiding in the prevention of neonatal inflammatory diseases and positively influencing subsequent health outcomes．Analysis of recent research literature reveals multiple mechanisms through which MDSCs contribute to neonatal immune regulation,including protective effects under specific pathological conditions,interactions with neonatal inflammatory responses,and potential impacts on long-term immune development．Therefore,a comprehensive understanding of the role of MDSCs in neonatal immunity not only helps elucidate their intricate regulatory mechanisms but also provides novel insights for developing strategies for the prevention and treatment of neonatal inflammatory diseases．

目的 研究内托生肌法治疗肉芽肿性乳腺炎溃后期的临床疗效。方法 63例符合肉芽肿性乳腺炎溃后期的患者,分为西药组31例和中药组32例。西医药组予常规激素、抗生素等治疗,中药组予内托生肌法,加减组方,两组治疗时间为6个月。比较两组患者的疾病转归、乳房外形评价、临床症状观察评分等指标。结果 中药组6个月治愈率高于西药组,中药组临床治愈18例（56.2%）、痊愈11例（34.4%）,相较于西药组临床治愈11例（35.5%）和痊愈9例（29%）;治疗后中药组乳房外形评价优于西药组,中药组临床症状评分较低,组间比较差异具有统计学意义。两组患者治疗前后免疫球蛋白IgA、IgG、IgM水平比较差异均未见统计学意义。中药组相较于西药组不良反应更少,患者依从性更高。结论 内托生肌法治疗肉芽肿性乳腺炎溃后期能促进肉芽肿创面愈合,加快肉芽组织新生,改善破溃流脓症状以及在恢复乳房外观方面具有明显的优势。

Objective To study the clinical efficacy of endotropic muscle-generating therapy in treating late-stage ulcerative granulomatous mastitis．Methods Sixty-three eligible patients were included in the western medicine group（31 cases）and the traditional Chinese medicine group（32 cases）．The western medicine group received conventional hormones and antibiotics,while the traditional Chinese medicine group received the endotropic muscle-generating method with adjustments．The treatment duration for both groups was six months．Disease regression,breast shape evaluation,clinical symptom observation scores,and other relevant indices of both groups were compared．Results The study found that the six-month cure rate in the traditional Chinese medicine group（56.2% clinically cured,34.4% cured）exceeded that of the western medicine group（35.5% clinically cured,29% cured）．Breast appearance evaluation in the traditional Chinese medicine group significantly better that of the western medicine group post-treatment,and clinical symptom scores were lower,demonstrating a statistically significant difference．Before and after treatment,there was no significant difference in the levels of immunoglobulins A,G,and M observed between the two groups．The traditional Chinese medicine group exhibited fewer side effects and higher patient compliance compared to the western medicine group．Conclusions The endotropic muscle-generating method,when employed to treat granulomatous mastitis in the late ulcerative stage,proves effective in promoting granulomatous wound healing,accelerating the generation of new granulation tissue,and improving ulceration and pus flow symptoms．Additionally,it contributes to the restoration of breast appearance．
