Study Design: Rabbit model study.

Objective: To examine whether cartilaginous endplate (CEP) destruction leads to endplate and vertebral marrow signal changes (Modic changes, MCs) on MR images.

Methods: Sixteen adult rabbits were used in the study and underwent an anterolateral procedure to expose the L2-6 intervertebral discs.

Background: The use of a fluid co-load has been shown to enhance hemodynamic stability and diminish the occurrence of hypotension after spinal anesthesia when paired with prophylactic norepinephrine. This research aimed to identify the effective dosages (ED and ED) of prophylactic norepinephrine boluses, in conjunction with a crystalloid co-load, for the prevention of hypotension after spinal anesthesia in cesarean delivery patients.

Methods: Patients were administered crystalloid co-loads at a dosage of 10 mL/kg, in addition to preventive norepinephrine dosages direct following spinal anesthesia administration.

Background: Annulus fibrosis (AF) defects have been identified as the primary cause of disc herniation relapse and subsequent disc degeneration following discectomy. Stem cell-based tissue engineering offers a promising approach for structural repair. Menstrual blood-derived mesenchymal stem cells (MenSCs), a type of adult stem cell, have gained attention as an appealing source for clinical applications due to their potential for structure regeneration, with ease of acquisition and regardless of ethical issues.

Objective: To introduce a technique of laminotomy using a common trephine to enlarge the interlaminar space at L4/5 segment for interlaminar endoscopic lumbar discectomy (IELD) and report the anatomical basis of this procedure, technical details, as well as primary clinical outcomes of a consecutive patient cohort with L4/5 lumbar disc herniation (LDH).

Methods: On anteroposterior fluoroscopy, the intersection of the medial edge of the inferior articular process and the inferior endplate of L4 vertebra was taken as the target. Using a common trephine, laminotomy was performed to remove a big portion of the posterior wall of the canal under the guidance of endoscopy.

Background: Currently, there is a paucity of recommendations in regards to dressing selection within the enhanced recovery after surgery protocol. We devised a new dressing system to accelerate the recovery after total hip arthroplasty (THA). We aimed to present our experience with this new dressing system as an adjunct to wound management in THA and to evaluate its performance.

Disc degeneration is the common pathology underlying various degenerative spinal disorders and currently there is no effective cure. Here, we found nucleus pulposus (NP) cell senescence was closely associated with the severity of disc degeneration, and exosomes (Exos) derived from mesenchymal stem cells (MSCs) ameliorated NP cell senescence and promoted extracellular matrix (ECM) deposition. As chitosan-based hydrogels have been widely used as vehicles to deliver Exos due to their prominent antibacterial capacity, biocompatibility, and biodegradability, we developed an Exos-laden hydrogel based on quaternized chitosan (QCS) and oxidized starch (OST) to treat disc degeneration.

Rheumatoid arthritis (RA) is a common autoimmune disease leading to pain, disability, and even death. Although studies have revealed that aberrant activation of STING was implicated in various autoimmune diseases, the role of STING in RA remains unclear. In the current study, we demonstrated that STING activation was pivotal in RA pathogenesis.

Lead (Pb) is a widespread environmental heavy metal toxicant and chronic Pb exposure can have irreversible effects on memory and cognitive function, which is closely related to dendritic spines. Studies have shown that SNX6 and Homer1 can regulate the growth of dendritic spines. We aimed to investigate the effect of Pb exposure on the dendritic spines in hippocampus, the expression of SNX6 and Homer1 in rats and PC12 cells.

Objective: To explore the effects of various left anterior descending (LAD) artery-blocked sites on the development of acute myocardial infarction (AMI) and malignant arrhythmia in a swine model.

Methods: Twenty-two pigs underwent occlusion of the coronary artery with balloon angioplasty were randomly divided into three groups according to the blocked site of the balloon: middle-site-blocked LAD group, bottom-third-blocked LAD group and control group. Then, the development of AMI and malignant arrhythmia, including ventricular tachycardia and ventricular fibrillation during the process of model creation, were recorded.

Objectives: Serum cystatin C has been established as a predictor of cardiovascular events. The aim of this study was to evaluate the role of cystatin C in determining the presence and the severity of patients with coronary artery disease (CAD).

Design And Methods: A total of 936 subjects without overt renal disease were included in this cross-sectional study.

Bariatric surgery has developed in western countries for more than 50 years. With the increase of obese patients in China, the surgical treatment of obesity anf diabetes become acceptable. it is important to review the history of bariatric surgery and summarize suitable procedures for Chinese bariatric surgery including Roux-en-Y gastric bypass, sleeve gastrectomy, and adjustable gastric band.

Objective: To evaluate the outcomes and factors related to weight loss after laparoscopic gastric bypass(LGBP) in obese patients.

Methods: Forty-one obese patients who underwent LGBP from May 2010 to December 2011 in the First Affiliated Hospital of Nanjing Medical University were followed up. The operative time, intraoperative complications, postoperative complications, preoperative body mass index(BMI), postoperative BMI, and excess weight loss rate(EWL) were determined and their correlation with efficacy were analyzed.

A large number of clinical studies indicate that bariatric surgery leads to improvement or resolution of type 2 diabetes. The outcomes vary depending on procedure adopted. Biliopancreatic diversion(BPD) is associated with the highest cure rate(98%), followed by Roux-en-Y gastric bypass(RGBP)(80%).
