KOA是临床上最常见,发病起源于关节软骨的慢性退行性关节疾病。近年来,应用黄芪治疗KOA的报道不断增多,并且开展了大量的机制研究。本文综述了黄芪在KOA治疗中的应用现状及研究进展,同时指出从PPAR-γ信号通路探索黄芪干预KOA的具体分子机制具有积极的理论和实践意义。

神经元特异性烯醇化酶(neuron-specific enolase, NSE)是糖酵解途径中一种重要的同工酶;特异性位于神经元和神经内分泌细胞中。小细胞肺癌(small cell lung cancer,SCLC)细胞浆内含有神经内分泌颗粒,具有神经内分泌分化的特征,为恶性程度高的神经内分泌系统肿瘤。因此,NSE是SCLC诊断中最敏感的肿瘤标志物,在SCLC的临床诊断、治疗、预后均有重要应用价值,科学合理联合检测肿瘤标记物,将能为临床诊疗工作提供有力的帮助。

与正常组织细胞微环境相比,肿瘤微环境具有一定的异质性,包括偏酸性、氧化还原状态失衡、存在高浓度活性氧以及酶过量表达等。根据以上肿瘤微环境特点,可设计出一系列通过各种特殊微环境响应型连接臂相连的小分子或聚合物前药纳米粒。其中,多柔比星阿霉素作为一类最常见的广谱抗肿瘤药物在治疗肿瘤的过程中发挥重要作用。文章探讨了在肿瘤微环境特异性的生理状态下针对不同微环境所设计的多柔比星前药及其释放特性等,归纳总结了肿瘤微环境响应型多柔比星前药的研究进展。

Compared with normal tissue cell microenvironment, there is some differences in tumor microenvironment, such as partial acidity, imbalance of redox state, high concentration of reactive oxygen species and cathepsin. According to the above characteristics of tumor microenvironment, a series of small molecule or polymer prodrug nanoparticles connected by various special microenvironment responsive structures can be designed. Doxorubicin, as one of the most common broad-spectrum antitumor drugs, plays an important role in the treatment of tumors. This review discusses the doxorubicin prodrug designed for different tumor microenvironments under the physiological state of tumor microenvironment specificity and their release characteristics, and summarizes the research progress of tumor microenvironment-responsive doxorubicin prodrug.

       随着糖尿病患者的增加,因肺炎住院的糖尿病患者数也呈现出明显上升趋势。由于糖代谢紊乱及机体免疫功能下降等因素,细菌在高血糖的机体环境中快速繁殖并分泌大量毒素,增加了抗菌药物使用的时间跨度和细菌清除难度,对患者预后造成了极大的威胁。文章主要对糖尿病合并细菌性肺炎患者的病原学特征、耐药情况及药物治疗等进行阐述,旨在进一步为临床预防和治疗提供参考依据。

        With the increasing incidence in diabetes, the number of hospitalized diabetes patients with pneumonia is also increasing. Due to factors such as glucose metabolism disorders and decreased immune function in the body, bacteria rapidly multiply and secrete a large amount of toxins in the hyperglycemic environment,increasing the duration of antibiotic use and the difficulty of bacterial clearance, posing a great threat to patient prognosis. This article mainly elaborates on the pathogenic characteristics, drug resistance, and drug treatment of diabetes patients with bacterial pneumonia, aiming to provide reference for the clinical prevention and treatment.

        儿童孤立性直肠溃疡综合征（SRUS）是一种较为罕见的慢性直肠疾病,儿童发病率低且缺乏明确统计学数据。该病主要表现为便血、排黏液便和排便不尽感,临床诊断较为困难,常易误诊为其他疾病。其发病机制尚不明确,可能与排便习惯异常、直肠黏膜异常、血管异常以及遗传易感性等多种因素有关,其中 CHEK2 基因的 p.H371Y 突变可能在发病机制中起关键作用。诊断需综合病史、体格检查以及排粪造影、超声内镜、肠镜检查与组织病理活检等多种辅助检查手段。治疗上目前尚无统一指南,主要包括改善饮食和排便习惯、生物反馈治疗、药物治疗、内镜下治疗和外科手术治疗等,但总体治疗难度较大且复发率较高。本文对儿童 SRUS 的流行病学、发病机制、临床表现、诊断和治疗等方面的研究进展进行综述,旨在提高临床医师对该病的诊疗水平,为未来进一步的研究提供参考依据。

       Solitary rectal ulcer syndrome（SRUS）in children is a chronic and benign disease of the rectum characterized by ulcers. The clinical incidence of SRUS in children is not high, but it is prone to misdiagnose and miss diagnosis,which can delay the optimal treatment opportunity. This article reviews the research progress on the epidemiology,pathogenesis, clinical manifestations, diagnosis and treatment of SRUS in children, aiming to improve the diagnostic and therapeutic level of clinicians.

股骨转子间骨折是最常见的髋部骨折,内固定手术为其目前治疗的首选方式。头颈钉位置是评估手术效果和判断治疗预后的重要因素,合适的置钉位置有利于稳定骨折、加速康复以及改善预后。目前头颈钉位置最经典的评估方式为尖顶距（TAD）,但TAD至今仍存在较多争议。近年来提出的轴刀角、尖颈距离比、偏心距（ED）以及标准化TAD（STAD）为临床实践拓展了新视野。文章通过对上述头颈钉位置的评估方法及局限性进行文献综述,旨在为临床手术置钉时提供相应的参考。ED和STAD的提出,为未来人工智能评估头颈钉位置提供了可能。

Femoral intertrochanteric fracture is one of the most common hip fractures, and the internal fixation is the preferred treatment. The position of cephalic fixator is an important factor to evaluate the effect of operation and the prognosis of treatment. Tip-apex-distance（TAD）is the most classical method to evaluate the position of cephalic fixator, but it is still controversial. In recent years, the axis-blade angle,tip-neck distance ratio, eccentric distance（ED）and standardized TAD（STAD）have been proposed,though with limitations, they also provide a new perspective for clinical practice. In this study, we reviewed the literature on the evaluation of the position of cephalic fixator in order to provide the corresponding references and guidance for the clinical operation of internal fixation. Both STAD and ED may be the theoretical possibility of artificial intelligence evaluation of the position of cephalic fixator in the future.

        胃食管反流病是一种以烧心和反流为主要症状的胃食管动力障碍性疾病，现有的常规治疗存在药物依赖，手术风险高且易复发等局限性，而经皮电刺激作为一种新兴疗法，在治疗动力障碍性疾病时具有非侵入性、可逆性及调节生理功能的优势。因此本研究为了探讨经皮电刺激治疗胃食管反流病的进展，现从胃食管反流病的神经调控生理、不同经皮电刺激对治疗胃食管反流病的研究以及应用效果等方面进行综述，以期为胃食管反流病提供新的诊断思路和方法。
