Safety and aesthetic outcomes of double purse-string suture nipple reconstruction in early breast cancer patients undergoing nipple resection and endoscopic skin-sparing mastectomy with breast reconstruction.

Background: The current surgical methods for managing incisions after nipple excision in breast reconstruction patients are limited. However, double purse-string suture (DPS) shows promise in the treatment of nipple excision. This study aimed to investigate the safety and aesthetic outcomes of DPS nipple reconstruction in early breast cancer patients who underwent endoscopic skin-sparing mastectomy (E-SSM) and breast reconstruction.

Methods: The clinical data of 25 patients who underwent endoscopic removal of injectable Amazingel with/without immediate prepectoral implant-based breast augmentation between April 2020 and January 2024 and met the selection criteria was retrospective analysed. The patients' age ranged from 33 to 73 years, with a mean of 50.

[Past and present of endoscopic surgery and robotic surgery in treatment of breast diseases].

Objective: To review the research progress related to endoscopic surgery and robotic surgery for breast diseases, aiming to provide references for clinical practice.

Methods: The recent domestic and international literature on endoscopic surgery and robotic surgery for breast diseases was reviewed, then the challenges in their development, the innovative evolution of endoscopic surgery combined with clinical practice by our team, and its clinical applications were summarized.

Results: Traditional endoscopic surgery, despite its advantages such as minimal invasiveness, good cosmetic outcomes, and high patient's satisfaction, has been limited in its development due to specific difficulties in establishing the operative field.

A novel technique of reverse-sequence endoscopic nipple-sparing mastectomy with direct-to-implant breast reconstruction: medium-term oncological safety outcomes and feasibility of 24-h discharge for breast cancer patients.

Background: Due to the short operation time and no need for special instruments, reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) with direct-to-implant breast reconstruction (DIBR) has been rapidly becoming popular in the last three years. However, there has yet to be an evaluation of its oncologic safety or the feasibility of discharging patients within 24 h.

Materials And Methods: In this single-centre retrospective cohort study, individuals diagnosed with stage 0-III breast cancer between May 2020 and April 2022 who underwent traditional open mastectomy or R-E-NSM with DIBR were included.

Single Axillary Incision Reverse Sequence Endoscopic Nipple-Sparing Mastectomy in the Management of Gynecomastia: Short-Term Cosmetic Outcomes, Surgical Safety, and Learning Curve of the Preliminary 156 Consecutive Procedures from a Prospective Cohort Study.

Background: Currently, a standard, optimal surgical procedure is still lacking for gynecomastia. Despite the development of a variety of surgical interventions, these techniques were often limited to patients with Simon I and II. The present study aimed to introduce a novel technique for all types and grades of gynecomastia, and reported the preliminary results.

Computational prediction of allergenic proteins based on multi-feature fusion.

Allergy is an autoimmune disorder described as an undesirable response of the immune system to typically innocuous substance in the environment. Studies have shown that the ability of proteins to trigger allergic reactions in susceptible individuals can be evaluated by bioinformatics tools. However, developing computational methods to accurately identify new allergenic proteins remains a vital challenge.

Three-Pedicle Reduction Mammaplasty Technique in the Treatment of Greater Breast Hypertrophy Patients With or Without Breast Cancer: Surgical and Patient-reported outcomes.

Background: Reduction mammoplasty (RM) is an important procedure in the management of symptomatic greater breast hypertrophy with or without early-stage breast cancer. We aim to introduce a new procedure: the three-pedicle reduction mammaplasty technique.

Methods: A prospectively maintained database was reviewed, and two prospectively registered clinical studies were included of all breast hypertrophy patients with or without breast cancer who underwent three-pedicle RM with inverted T incision at West China Hospital or the Fourth People's Hospital of Sichuan Province from 2018 to 2022.

Structure-Guided Designing Pre-Organization in Bivalent Aptamers.

Multivalent interaction is often used in molecular design and leads to engineered multivalent ligands with increased binding avidities toward target molecules. The resulting binding avidity relies critically on the rigid scaffold that joins multiple ligands as the scaffold controls the relative spatial positions and orientations toward target molecules. Currently, no general design rules exist to construct a simple and rigid DNA scaffold for properly joining multiple ligands.

Monitoring microbial communities in intensive care units over one year in China.

Healthcare-associated infections (HAIs) seriously threaten patient health in intensive care units (ICUs). Profiling the microbial composition and diversity in ICU is important to prevent HAI-related spreading. Given that microbial communities vary across different environments, the time-scale characteristics of pathogens in ICUs have not been explored in China.

[Application of three-pedicle reduction mammaplasty in breast cancer patients with moderate or greater breast hypertrophy and/or moderate-to-severe breast ptosis].

Objective: To explore the application and effectiveness of three-pedicle reduction mammoplasty in breast cancer patients with moderate or greater breast hypertrophy and/or moderate-to-severe breast ptosis.

Methods: The clinical data of 15 breast cancer female patients with hypertrophy and/or moderate-to-severe breast ptosis treated by three-pedicle reduction mammaplasty with inverted T incision between January 2019 and March 2021 were retrospectively analysed. The patients were aged 31-58 years, with a median age of 39 years.

Characteristics of Pulmonary Auscultation in Patients with 2019 Novel Coronavirus in China.

Background: Effective auscultations are often hard to implement in isolation wards. To date, little is known about the characteristics of pulmonary auscultation in novel coronavirus (COVID-19) pneumonia.

Objectives: The aim of this study was to explore the features and clinical significance of pulmonary auscultation in COVID-19 pneumonia using an electronic stethoscope in isolation wards.

Spleen and splenic vascular involvement in acute pancreatitis: an MRI study.

Background: To investigate the spleen and splenic vascular involvement in acute pancreatitis (AP) and their correlations with the severity of AP using magnetic resonance imaging (MRI).

Methods: MRI of 239 patients with AP was retrospectively reviewed to assess splenic and splenic vascular complications, and the severity of AP. The severity of AP was graded by the MRI severity index (MRSI) and the New Revised Classification of AP 2012.

T-cell immunoglobulin mucin-3 expression in invasive ductal breast carcinoma: Clinicopathological correlations and association with tumor infiltration by cytotoxic lymphocytes.

As a negative regulatory molecule, T-cell immunoglobulin and mucin domain-3 (Tim-3) is closely associated with tumor immunological tolerance. The aim of this study was to investigate Tim-3 expression in invasive ductal breast cancer (IDC), its effect on clinicopathological parameters and its association with cytotoxic lymphocyte infiltration. Tim-3 protein expression was measured in 150 paraffin-embedded IDC specimens and 100 paired normal breast tissue specimens by immunohistochemistry.

Caspase-3 feedback loop enhances Bid-induced AIF/endoG and Bak activation in Bax and p53-independent manner.

Chemoresistance in cancer has previously been attributed to gene mutations or deficiencies. Bax or p53 deficiency can lead to resistance to cancer drugs. We aimed to find an agent to overcome chemoresistance induced by Bax or p53 deficiency.
