Study on the risk factors of postoperative wound complications in patients with ankle fracture.

Wound complications after surgery for ankle fractures can lead to catastrophic consequences. The purpose of this study was to evaluate the risk factors of postoperative wound complications in patients with ankle fracture and to determine their effects on prognosis. 200 patients with ankle fracture treated in our hospital from October 2021 to December 2023 were analysed retrospectively.

Study on Diesel Engine Selective Catalytic Reduction Performance at Different Atmospheric Pressures Using the Response Surface Method.

Nitrogen oxides (NO ) are the main emissions of diesel engines. Selective catalytic reduction (SCR) is the main technology used to reduce NO emissions from diesel engines. NO conversion efficiency and ammonia (NH) escape are the main indicators to evaluate SCR performance.

[Treatment analysis of complex Schatzker type Ⅳ tibial plateau fractures].

Objective: To explore treatment strategy for complex Schatzker Ⅳ tibial plateau fracture.

Methods: Forty-one patients with complex Schatzker type Ⅳ tibial plateau fractures were treated from January 2016 to January 2021, including 28 males and 13 females, aged from 19 to 65 years old with an average of (35.3±19.

Pathological Responses of the Primary Tumor and Locoregional Lymph Nodes After Neoadjuvant Immunochemotherapy in Esophageal Squamous Cell Cancer.

Background: The current study attempted to describe the specific patterns of pathological tumor response and locoregional node metastases from surgically resected esophageal squamous cell carcinoma after neoadjuvant immunochemotherapy (NAIC), as well as to explore the association between clinicopathological characteristics and such oncological patterns.

Methods: Fifty-one patients with cT3 or deeper esophageal squamous cell cancer underwent subtotal esophagectomy after NAIC. The NAIC regimen included intravenous administration of platinum-based and docetaxel- and taxane-based chemotherapeutics along with a 200 mg fixed dose of one programmed death 1 (PD-1) inhibitor, given every 3 weeks.

Multiple-bar Nuss operation: an individualized treatment scheme for patients with significantly asymmetric pectus excavatum.

Background: Research into multiple-bar Nuss operations for the treatment of wide-range or significantly asymmetric pectus excavatum is rarely reported. This paper aims to explore the curative effects of multiple-bar Nuss operations on wide-range or significantly asymmetric pectus excavatum.

Methods: We reviewed the clinical data of 153 patients with pectus excavatum who were treated in our hospital from September 2006 to August 2014.
