糖尿病已成为全球最严重的健康问题之一。需要白内障手术的糖尿病患者也日益增多,虽然糖尿病的眼表并发症很常见,但由于糖尿病患者全身和眼部疾病十分复杂,使得眼前段如角结膜和泪腺的糖尿病并发症往往被忽视。糖尿病患者白内障超声乳化术有引发或加重眼前节疾病的风险,包括干眼病（DED）、角膜上皮糜烂、上皮缺损迁延不愈,甚至威胁视力的角膜溃疡。这些风险里最为常见的是DED,并且可能因白内障超声乳化手术而加重。眼科医生需要在手术前预先评估已存在的DED是否需要术前治疗,并且需要注意在已存在 DED 的情况下,各项术前检查数据测量的准确性会降低,以及尽可能减少对眼表造成损害的各种手术因素;并考虑通过管理减少术后 DED。本综述就评估白内障超声乳化术对合并糖尿病的老年性白内障患者的眼表术中的影响因素进行分析。

Diabetes mellitus(DM)has become one of the most serious health problems in the world. The number of diabetic patients requiring cataract surgery is also increasing. Although ocular surface complications of DM are common,the complexity of systemic and ocular disease in diabetic patients makes diabetic complications in the anterior segment,such as the cornea and lacrimal gland,often be overlooked. Phacoemulsification in diabetic patients carries the risk of triggering or exacerbating ocular segment disease,including dry eye disease,corneal epithelial erosion,persistent epithelial defects and even vision-threatening corneal ulcers. The most common of these risks is dry eye disease,and it can be exacerbated by cataract phacoemulsification. Ophthalmologists need to preemptively assess the need for preoperative treatment of pre-existing dry eye disease(DED),be aware of the reduced accuracy of preoperative data measurements in the presence of DED,and minimize surgical factors that can damage the ocular surface;and consider management to reduce postoperative DED. In this review,we analyze the factors that influence phacoemulsification in ocular surface surgery for senile cataract patients with diabetes.

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。

The imbalance of immune function in severely burned patients can easily lead to wound infection,systemic inflammatory response syndrome,sepsis,septic shock and other complications,which increase the mortality of patients. 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.

嵌合基因是指由两个或多个原本不连续的基因片段重组而成的新基因,它们可以通过基因组重排、转录诱导等机制产生。嵌合基因在正常生理和发育过程中具有重要的功能和调控作用。嵌合基因可以改变原有基因的表达水平、编码蛋白质的结构和功能、信号通路的激活和抑制等,从而促进肿瘤细胞的增殖、侵袭、转移和耐药性。近年来,随着高通量测序技术的发展和应用,越来越多的嵌合基因被发现和鉴定,它们在不同类型的肿瘤中具有不同的表达模式和功能作用,为肿瘤的分子诊断、预后评估和靶向治疗提供了新的机会和挑战。本文旨在对嵌合基因产生的机制、检测方法和在肿瘤中的功能和应用等方面进行综述,为进一步认识嵌合基因在肿瘤进展中的功能机制及其精准化治疗提供参考。

Chimeric genes refer to novel genes formed by the recombination of two or more originally non-contiguous gene fragments through mechanisms like genomic rearrangement and transcriptional induction．They play important roles in physiological and developmental regulation．Chimeric genes can alter the expression,structure and function of original genes,modulate signaling pathway activation and inhibition,and thereby promote tumor cell proliferation,invasion,metastasis and drug resistance．In recent years,with the development and application of high-throughput sequencing technologies,increasing numbers of chimeric genes have been discovered and identified．They demonstrate different expression patterns and functional roles in various tumor types,providing new opportunities and challenges for molecular diagnosis,prognostic assessment and targeted therapy of cancers．This review summarizes the mechanisms of chimeric gene formation,detection methods and their functions and applications in tumors,to provide insights into the functional mechanisms of chimeric genes in tumor progression and their implications for precision treatment．

Chronic kidney disease (CKD) is a series of chronic disease groups associated with high morbidity and mortality. Hemodialysis and kidney transplantation are the only choices for end-stage renal disease. According to the literature report, it is shown that small molecule and nucleic acid drugs have great potential in CKD treatments with an unsatisfied therapeutic efficacy because of the lack of specific targeting. Thus, it is necessary to develop a new strategy. Nanocarriers have been widely used in biomedical fields due to their excellent physical and chemical properties. In this review, we have summarized the recent advances in applying functional nanocarriers to deliver the small molecules and nucleic acid drugs in the treatment of CKD.

实体肿瘤物理和化学微环境异常阻碍了肿瘤与外界进行物质交换,降低了药物渗入肿瘤组织,是肿瘤对放化疗抵抗的重要原因。目前,已有多种针对肿瘤微环境各个组分的治疗方法,如使血管正常化、降低肿瘤间质液压、降解细胞外基质等,以达到增强药物等的渗出,从而增强肿瘤治疗效果。声学调控是改变肿瘤理化微环境的一种有效方法,本文对声学调控其中几个主要的机制和研究进展进行综述,以期为临床肿瘤治疗提供新思路。
