Objective To establish and identify the rabbit model of lumbar disc with severe degeneration．Methods Six New Zealand white rabbits were selected,lumbar X-ray and Pfirrmann grade by MR scan were performed before surgical intervention．Along the space of obliquus externus abdominis and psoas major,the front edge of L2 to L3 was exposed．Then,the nucleus pulposus and part of annulus fibrosus were removed to imitate severe degeneration of lumbar disc．After 6 weeks of rearing,the operated lumbar disc was graded by MR scan,confirming that the lumbar disc met the image of severe degeneration,and then exposed the intervertebral space and injected bone cement．One week later,the anterior lumbar X-ray and the MRI scan for Pfirrmann grading were taken．The animals were sacrificed and dissected to check the bone cement filling in the intervertebral disc．Results The rabbit MR Pfirrmann grade of intervertebral disk was V after 6 weeks of first operation．One week after intervertebral cement injection,the MR Pfirrmann grade was Ⅳ．The surgical segment X-ray was taken one week after the cement injection,which showed that the cement was well filled in the L2-L3 gap and the vertebral space height was close to normal．Animals were sacrificed and dissected,the lumbar intervertebral disc was well filled with cement without shedding or loosening．Conclusions A reliable animal model of lumbar disc with severe degeneration in New Zealand white rabbits can be obtained by injecting cement into the intervertebral space after 6 weeks of removal of the intervertebral disc nucleus pulposus and part of the annulus fibrosus through the obliquus externus abdomins and psoas major intervertebral space．

严重烧伤后患者免疫功能的失调,易导致创面感染、全身炎症反应综合征、脓毒症、感染性休克等并发症,增加患者病死率。免疫细胞功能适度的活化将有助于烧伤患者抵御外界病原体的侵袭、促进创面的愈合,但功能过度激活或者功能低下,则会引发一系列严重的后果。本文旨在归纳严重烧伤后中性粒细胞、单核/巨噬细胞、肥大细胞、NK细胞及T淋巴细胞等免疫细胞的功能变化与炎症反应之间的关系,为完善烧伤患者诊疗、减少并发症、改善预后提供新的思路。

Moderate activation of immune cell function will help burned patients to resist the invasion of external pathogens and promote wound healing,but excessive activation or low function can lead to a series of serious consequences. The purpose of this paper is to summarize the relationship between the functional changes of immune cells such as neutrophils,monocytes/macrophages,mast cells,NK cells,T lymphocytes and inflammatory reaction after severe burns,and to provide new ideas for improving the diagnosis and treatment of burned patients,reducing complications and improving the prognosis.

目的 探讨结核病相关重症患者的诊治特点,提高此类疾病的诊治水平。方法 回顾性分析2020年7月—8月我科收住的4例临床表现类似的结核病相关重症患者的临床资料。结果 4例患者均诊断为活动性结核病或结核潜伏感染,均为合并1个或多个器官功能衰竭的重症患者,均表现为发热、血小板减少、肝肾损伤,经予以个体化的积极抢救治疗,均获得满意疗效。结论 结核病相关重症患者往往病情复杂危重,可能临床特点相似,但实际病因不同,因而治疗重点各异,需临床医生认真剖析病情,找到关键病因,以尽量挽救患者生命。

Objective To explore the characteristics of diagnosis and treatment of severe tuberculosis-related patients and improve diagnosis and treatment of such diseases. Methods Retrospectively analyzed the clinical data of 4 severe tuberculosis-related patients with similar clinical symptoms admitted to our department from July to August, 2020. Results All 4 patients were diagnosed as active tuberculosis or latent tuberculosis infection, with one or several organs failure, fever, thrombocytopenia, liver and renal injury. They were given individualized positive rescue treatment, and achieved satisfying outcomes. Conclusions Severe tuberculosis-related patients often have complex and critical conditions, and may have similar clinical characteristics, but the actual causes are different, so the treatment focuses are different. Clinicians need to carefully analyze the condition, find out the key causes, and try to save the lives of patients.

目的 对儿童重症肺炎支气管肺泡灌洗液(BALF)进行病原学分析及疾病预后的分析。方法 本研究选取2019年3月—2020年12月在我院儿科住院并进行肺泡灌洗治疗的40例重症肺炎患儿作为研究对象。通过对这些患儿在感染急性期肺泡灌洗液中的细菌、真菌、肺炎支原体等进行病原学检查以及T 淋巴细胞亚群的检测,了解台山地区儿童重症肺炎病原体情况及耐药性、T淋巴细胞亚群与疾病严重程度、预后评估的关系。结果 BALF病原学检测结果分析中,肺炎支原体27例,肺炎支原体+肺炎链球菌5例,肺炎支原体+中间葡萄球菌2例,肺炎支原体+铅黄肠球菌1例,肺炎支原体+嗜麦芽假单胞菌2例,病原菌阴性3例;本组病例血清T细胞亚群检测结果显示:大部分病例CD3⁺、CD4⁺、CD8⁺及CD4⁺/CD8⁺水平有不同程度的下降。其中CD3⁺水平下降的有6例,CD4⁺水平下降的有16例,CD8+水平下降的有17例,CD4⁺、CD8⁺水平同时下降的有14例,CD3⁺、CD4⁺、CD8⁺水平同时下降的有4例;BALF细胞总数(3673.1±377.9)×10⁶ /L,巨噬细胞比例(23.6±17.6)%,淋巴细胞(22.1±16.2)%,中性粒细胞(46.5±24.8)%。结论 病原学分析儿童重症肺炎BALF的主要病原菌为肺炎支原体,血清T细胞亚群检测大多表现为CD4⁺、CD8⁺水平下降。

Objective To analyze the etiology of bronchoalveolar lavage fluid and prognosis of children with severe pneumonia. Methods In this study, 40 children with severe pneumonia who were hospitalized in the pediatrics department of our hospital and underwent alveolar lavage treatment from March 2019 to December 2020 were selected as the research objects. Through the detection of pathogens such as bacteria, fungi, Mycoplasma pneumoniae and T lymphocyte subsets of these children in the acute phase of infection, we can understand the pathogens and drug resistance of children with severe pneumonia in Taishan area and the relationship among drug resistance, T lymphocyte subsets and disease severity and prognosis assessment. Results In the analysis of the BALF pathogenic test results, there were 27 cases with Mycoplasma pneumoniae, 5 cases with Mycoplasma pneumoniae+Streptococcus pneumoniae, 2 cases with Mycoplasma pneumoniae+Staphylococcus intermedius, 1 case with Mycoplasma pneumoniae+Enterococcus casseliflavus, 2 cases with Mycoplasma pneumoniae+Pseudomonas maltophilia and 3 cases were pathogenic bacteria negative. The test results of serum T cell subsets of these cases showed that most of the cases had different degrees of decline in the levels of CD3⁺, CD4⁺, CD8⁺ and CD4⁺/CD8⁺. Among them, CD3⁺ levels decreased in 6 cases, CD4⁺ levels decreased in 16 cases, CD8⁺ levels decreased in 17 cases, CD4⁺ and CD8⁺ levels decreased in 14 cases, and CD3⁺, CD4⁺, and CD8⁺ levels decreased in 4 cases; total cell number of BALF was (3 673.1±377.9)×10⁶/L, the proportion of macrophages was (23.6±17.6)%, lymphocytes had (22.1±16.2)%, and neutrophils had (46.5±24.8)%. Conclusions Pathogenic analysis showed that the main pathogen of BALF in children with severe pneumonia is Mycoplasma pneumoniae, and the detection of serum T cell subsets mostly showed a decrease in CD4⁺ and CD8⁺ levels.
