Background: The aim of this study was to compare the effectiveness of two different vitrification methods and slow freezing in terms of the recovery of endocrine function, follicular morphology and proliferation, apoptosis of stromal cells, and angiogenesis after heterotopic transplantation of human ovarian tissue.
Methods: Ovarian tissue from young women aged 29 to 40 was subjected to two vitrification methods and one slow freezing method. The thawed ovarian tissue was then transplanted into nude mice and divided into three groups (VF1 group, VF2 group, SF group) according to the different freezing methods.

Background: Hallux valgus (HV) is a multiplanar deformity and surgical treatment is often guided by two-dimensional radiographic parameters. This study assessed the reliability and accuracy of the AIR classification(The first metatarsal head's lateral edge can be delineated as angular (type A), round (type R), or intermediate (type I) through visual inspection or circle measurements on weight-bearing radiographs.)commonly used in clinical settings to categorize the shape of the lateral edge of the first metatarsal head, against measurements from weight-bearing computed tomography (WBCT).

Herein, we conducted a retrospective observational study from September 26, 2020 to September 30, 2023 to assess PIV epidemiology in Wuhan, China, as well as the clinical characteristics of PIV infections. In total, 14,065 inpatients with ALRTIs were enrolled, of which 936 were identified to have PIV infection.

Recent studies highlight the pivotal role of the gut microbiome (GM) in mediating the therapeutic effects of TCM. However, it is unclear whether the GM contributes to Gui-Shen-Wan's therapeutic restoration of ovarian functions.

With global environmental problems severer, exploring how to improve the eco-environment of LFS through institutional change is receiving increasingly concern. Based on macro and micro data from Inner Mongolia, this study examines the impacts of land titling on the eco-environment of LFS, explores the potential mechanisms, and analyzes the heterogeneity in terms of farm size by applying GIS spatial analysis and time-varying difference-in-difference (TV-DID) model.

The numerical simulations using empirical parameters have proffered insights into the theoretical migration and settling rates of Po aerosols. However, the scarcity of platform tests has impeded the acquisition of particle size distributions and settling velocity, thus weakening the mutual confirmation between experimental and theoretical validation.

Methods: This multicentre retrospective cohort study involved 40 patients with mutations and 40 age-matched and gender-matched inherited retinal diseases (IRDs). The detailed phenotyping and genotyping characteristics and genotype‒phenotype correlations of the patients were analysed.
Soybean provides protein, oil and multiple health-related compounds. Understanding the effects of structural variations (SVs) on economic traits in modern breeding is important for soybean improvement. Here we assembled the high-quality genome of modern cultivar Nongdadou2 (NDD2) and identified 25,814 SV-gene pairs compared to 29 reported genomes, with 13 NDD2-private SVs validated in 547 deep-resequencing (average = 18.

Currently, there is a lack of consensus regarding its treatment strategies. The purpose of this study was to investigate the outcomes of one-stage arthroscopic ankle and tibiotalocalcaneal (TTC) arthrodesis with external fixation in the treatment of septic ankle and hindfoot arthritis.

A common adjuvant therapy is the stimulation of the Yanglingquan point (GB34). Acupoint catgut embedding (ACE), an acupoint stimulation therapy, may be a better treatment for choledocholithiasis.

However, there are currently no standardized guidelines for surgical procedures and complication management. The aim of this study is to investigate the effect of bone lengthening with external fixation by minimally invasive osteotomy based on Ilizarov technique in the treatment of congenital brachymetatarsia.

However, the neural signatures of DMN subsystems in MDD after low resistance Thought Induction Psychotherapy (TIP) remain incompletely understood. We collected functional magnetic resonance imaging data from 20 first-episode, drug-naive MDD and 20 healthy controls (HCs).
View Article and Find Full Text PDFObjective: Distal tibial deformities can significantly impact patients if left uncorrected, often leading to pain, alterations in gait, and the eventual development of post-traumatic arthritis. The criteria for surgical correction in these patients continues to be a subject of debate, while supramalleolar osteotomy (SMO) is an effective method for correcting distal tibial deformities. The purpose of this study was to evaluate and compare the clinical results of SMO using internal fixation or using computer-assisted hexapod external fixator in the treatment of distal tibial deformity.
View Article and Find Full Text PDFObjective: Although several reconstructive methods have been developed to manage large segmental tibial bone defects including bone transport (distraction osteogenesis), contralateral fibular graft, allograft, tibiofibular synostosis, Masquelet technique, and 3D printed scaffold, neglected large tibial defects in adults remain challenging problems. This study describes gradual transverse transport of naturally tibialized fibula using hexapod frames in management of adult patients with neglected large tibial defects.
Methods: We retrospectively reviewed four cases of transverse transport of naturally tibialized fibula from November 2018 to February 2022.
Purpose: Prior research had indicated a relationship between fibrinogen and stroke-associated pneumonia (SAP), yet the nature of this relationship had not been thoroughly investigated. Therefore, this study was designed to elucidate the prognostic value of fibrinogen levels in forecasting the occurrence of SAP among patients with acute ischemic stroke (AIS).
Patients And Methods: In this retrospective cross-sectional analysis, we included 1092 patients who had experienced AIS and were admitted to our facility within 72 h of the onset of their symptoms.
