A new approach to overcoming resistance to immunotherapy: nanotechnology.

Immunotherapy for immune response has ushered in a new era of cancer treatment. In recent years, new immunotherapeutic agents have been introduced into clinical trials and even approved for marketing. However, the widespread use of immunotherapeutic agents faces an unavoidable challenge: immunotherapy does not work at all for some patients, or has good efficacy in the initial phase, but immunotherapy resistance develops within a short period of time, and immunotherapy can also cause serious adverse effects such as autoimmune inflammation and non-specific inflammation.

Timing of endoscopy for acute variceal bleeding in patients with cirrhosis (CHESS1905): A nationwide cohort study.

Background: Endoscopy plays an important role in the management of acute variceal bleeding (AVB) in patients with cirrhosis. This study aimed at determining the optimal endoscopy timing for cirrhotic AVB.

Methods: Patients with cirrhosis with AVB across 34 university hospitals in 30 cities from February 2013 to May 2020 who underwent endoscopy within 24 hours were included in this study.

Antitumor therapy for breast cancer: Focus on tumor-associated macrophages and nanosized drug delivery systems.

Background: In breast cancer (BC), tumor-associated macrophages (TAMs) are an important component of the tumor microenvironment and are closely related to poor prognosis. A growing number of studies have focused on the role of TAMs in BC progression and therapeutic strategies targeting TAMs. As an emerging treatment, the application of nanosized drug delivery systems (NDDSs) in the treatment of BC by targeting TAMs has attracted much attention.

Treatment Strategies in Emergency Endoscopy for Acute Esophageal Variceal Bleeding (CHESS1905): A Nationwide Cohort Study.

Background And Aims: Emergency endoscopy is recommended for patients with acute esophageal variceal bleeding (EVB) and their prognosis has improved markedly over past decades due to the increased specialization of endoscopic practice. The study aimed to compare outcomes following emergency endoscopic injection sclerotherapy (EIS) and endoscopic variceal ligation (EVL) in cirrhotic patients with acute EVB.

Methods: Cirrhotic patients with acute EVB who underwent emergency endoscopy were retrospectively enrolled from 2013 to 2020 across 34 university hospitals from 30 cities.

Safety and immunogenicity of COVID-19 vaccination in patients with non-alcoholic fatty liver disease (CHESS2101): A multicenter study.

Background & Aims: The development of COVID-19 vaccines has progressed with encouraging safety and efficacy data. Concerns have been raised about SARS-CoV-2 vaccine responses in the large population of patients with non-alcoholic fatty liver disease (NAFLD). The study aimed to explore the safety and immunogenicity of COVID-19 vaccination in NAFLD.

Long-term response to second-line afatinib treatment for advanced squamous cell carcinoma non-small cell lung cancer: a rare case report.

The ErbB family is composed of four cell membrane receptors: ErbB-1 (epidermal growth factor receptor or human epidermal growth factor receptor [HER]1), ErbB-2 (HER2), ErbB-3 (HER3), and ErbB-4 (HER4). All members of the ErbB family play a critical role in regulating cell growth, proliferation and migration of tumours. Afatinib is an irreversible ErbB family inhibitor that is approved for second-line treatment of advanced squamous cell carcinoma (SqCC) that has progressed following platinum-based chemotherapy.

Abdominal skin inflammation as an initial symptom of a perforating gastric foreign body: A case report.

Rationale: Foreign bodies are frequently ingested, but only approximately 1% of them cause perforation. Perforations in the lesser curvature of the stomach are exceedingly rare. Here, we report a case of gastric perforation in the lesser curvature caused by a foreign body.

[PROCEDURE OF RECONSTRUCTING TRANSVERSE ARCH OF THE FOREFOOT BY TRANSFERING TENDONS FOR CORRECTING HALLUX VALGUS].

Objective: To explore the effectiveness of the procedure of reconstructing the transverse arch of the forefoot by anastomosing adductor hallucis and abductor hallucis tendons in correcting hallux valgus.

Methods: A retrospective analysis was made on the clinical data from 28 patients (40 feet) with hallux valgus treated with the procedure of reconstructing the transverse arch of the forefoot by anastomosing adductor hallucis and abductor hallucis tendons between January 2010 and January 2014. There were 3 males (6 feet) and 25 females (34 feet), with an average age of 51.
