肝细胞生长因子促进培养的兔胃粘膜细胞损伤的修复

分离家兔胃粘膜细胞，培养48h细胞融合成片后，造成约2mm2的无细胞区，作为损伤修复模型进行实验。结果：空白对照组约48h完全修复，而肝细胞生长因子（HGF，50μg／L）组24h就修复完毕。其中对照组损伤周边的胃粘膜细胞游走速度为（16．62±0．38）μm／h，而HGF组达（23．90±0．68）μm／L（P＜0．01）；模型制作后12～24h五溴脱氧尿核苷标识率，HGF组（7．6％）约是对照组（0．5％）的15倍。表明HGF有显著促进胃粘膜细胞游走与增殖的功能。提示HGF在胃炎、胃溃疡等疾病的修复过程中可能起着重要作用。     

ERCC1､RRM1预测NSCLC患者GP方案化疗敏感性的对比研究

目的:对比切除修复交叉互补基因1(excision repair cross-complementing rodent repair deficiency,complementationgroup1,ERCC1)和核苷酸还原酶M1(ribonucleotide reductase M1,RRM1)低表达患者选择健择联合顺铂(gemcitabine andcisplatin,GP)方案和未经筛选经验性选用GP方案治疗晚期非小细胞肺癌(non-small-cell lung carcinoma,NSCLC)的临床疗效。方法:采用前瞻性的方法,根据组织标本是否适宜使用免疫组织化学方法检测分子标志物,在确诊为晚期NSCLC的患者中,ERCC1和RRM1低表达者归为A组,未经分子标志物检测的经验治疗者归为B组,经过4～6个周期的GP方案化疗,观察两组的疗效、无进展生存期(progressive-free survival,PFS)、总生存期(overall survival,OS)及化疗过程中的不良反应。结果:基于分子标志物结果选用GP方案较经验性选用GP方案有效率明显提高(χ2=5.377,P=0.02),PFS明显延长(P=0.03),差异有统计学意义;两组OS无显著性差异;不良反应无明显差异。结论:对ERCC1和RRM1低表达患者选择GP方案可以明显提高化疗有效率。     

Arthroscopic Intra‐Articular Repair of the Torn Subscapularis Tendon with Single Anterior Portal,Single Suture Anchor,and X‐Shaped Fixation Technique

Subscapular tendon plays an important role in shoulder joint function. With the advance of magnetic resonance imaging technology and the popularization of arthroscopic shoulder surgery, subscapularis tears have been increasingly detected. However, reduction and fixation of subscapular tendon tears appears to be technically challenging. This study aims to describe an arthroscopic intra‐articular X‐shaped fixation technique: a procedure of subscapularis tendon repair performed with the aid of a suture passer using only a single anterior portal and a single suture anchor. By incorporating the advantages of a single anterior working portal for anchor placement and tear repair, this technique provides an easier way to use suture lasso and make knots in a limited working space, and the whole procedure is minimally invasive with a short learning curve. This technique has been applied in patients with subscapularis tears involving no intraoperative or postoperative complications. Our technology offers a valuable new treatment option for subscapularis tears.

Comparative Analysis of Domestic and International Test Guidelines for Various Concrete Repair Materials

The number of aged bridges among concrete structures is increasing. Therefore, to increase their lifespans, repair and reinforcement schemes ought to be implemented. This study selected various repair materials according to crack-surface treatment, crack-filling, and crack-injection methods. These repair materials were evaluated using various test methods proposed by the Korean Standards and the American Society for Testing and Materials for structure protection, structure restoration, and crack repair; the results were analyzed and compared. Consequently, the structure restoration material exhibited a similar freezing–thawing trend as that of chloride, while also exhibiting similar flexural, compressive, bond, and splitting-tensile strengths. However, chloride yielded performance differences (up to two-fold) depending on the type of material used for comparison. The crack-repair material yielded similar trends only for bond strength but yielded differences (up to 2–4-fold) in tensile, compressive, and flexural strengths depending on the material used for comparison. These results confirmed that crack-repair materials exhibit significant differences in performance depending on the manufacturer compared with structure protection and structure restoration materials. Therefore, it is expected that repair materials appropriate for usability, durability, and structure safety, while also being environmentally friendly, could be used in future bridge repairs based on these test evaluations.     

腹部带蒂含真皮下血管网超薄皮瓣在手部损伤修复中的应用价值

目的：探讨腹部带蒂含真皮下血管网超薄皮瓣在手部损伤修复中的临床效果。方法：对我院接受手部损伤修复的60例患者随机分为实验组和对照组。对照组采用常规腹部带蒂皮瓣方法修复,实验组采用腹部带蒂含真皮下血管网超薄皮瓣修复,比较两组修复效果。结果：实验组12例感觉功能恢复评分为5分,患者感觉功能恢复良好,6例患者评分为4分,修复总有效率为90％（27／30）高于对照组（83．3％）;实验组修复时间为（71．9±12．6）min多于对照组（41．3±10．3）min;实验组修复过程中的出血量为（20．6±5．2）mL、患者修复后住院时间为（2．6±0．4）d,对照组住院时间为（3．5±4）周,实验组住院时间明显优于对照组（P＜0．05）;修复后实验组有1例患者出现并发症（2．5％）低于对照组（P＜0．05）。结论：采用腹部带蒂含真皮下血管网超薄皮瓣在手部损伤修复中效果较好,值得推广应用。     

Targeting Jab1/CSN5 in nasopharyngeal carcinoma

Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus-associated head and neck cancer that is most common in eastern Asia. Epstein-Barr virus infection, environmental factors, and genetic susceptibility play important roles in NPC pathogenesis. Jab1/CSN5 is a multifunctional protein that participates in affecting integrin signaling, controlling cell proliferation and apoptosis, and regulating genomic instability and DNA repair. Correlation of Jab1/CSN5 overexpression with poor prognosis for NPC provides evidence that it is involved in the tumorigenic process. In this review, we highlight recent advances in studies of the oncogenic role of Jab1/CSN5 in NPC and its potential as a therapeutic target for this cancer.
