METHODS: S G C-7901 c el ls were t reat ed wi t h H pylori SS1-LPS in the presence or absence of pretreatment for 1 h with viable LBG or supernatant recovered from LBG culture MRS broth (LBG-S ). Cellular lysates were prepared for Western blot with anti-TLR4, anti-transforming growth factor β-activated kinase 1 (TAK1), anti-phospho-TAK1, anti-nuclear factor κB (NF-κB), anti-p38 mitogen-activated protein kinase (p38MAPK), and anti-phospho-p38MAPK antibodies. The amount of IL-8 in cell culture medium was measured by ELISA. R E S U LT S : H p y l o r i S S 1 -L P S u p -r e g u l a t e d t h eexpression of TLR4, stimulated the phosphorylation of TAK1, subsequently enhanced the activation of NF-κB and the phosphorylation of p38MAPK in a timedependent manner, leading to augmentation of IL-8 production in SGC-7901 cells. Viable LBG or LBG-S pretreatment attenuated the expression of TLR4, inhibited the phosphorylation of TAK1 and p38MAPK, prevented the activation of NF-κB, and consequently blocked IL-8 production.

Background. Despite the danger of infection during the outbreak of the 2019 novel coronavirus (COVID-19) in Wuhan, many patients still need surgical treatment. Most elective surgeries were delayed because of the public health emergency. However, when patients have life-threatening emergencies or illnesses, surgeries are often needed as soon as possible. Moreover, due to hospital overcrowding during the COVID-19 outbreak, healthcare professionals initially struggled to address the issue due to a lack of experience. This is especially true for day surgery centers with higher patient mobility. Methods. We remodeled pathways to separate patients and medical personnel to minimize the COVID-19 infection rate. Further, strategies for medical staff education and potential patient education, ward disinfection and maintenance, setup with 3 more screening stations, patient and companion management, medical staff management, and perioperative management were implemented before starting elective day surgery. Results. From February 11 to March 11 in 2020, 202 day surgeries were performed. These were all elective surgeries and included ultrasound-guided Mammotome biopsy, endoscopic polypectomy, hernia repair, pediatric surgeries, cholecystectomy, choledochoscopy, radical mastectomy, percutaneous transhepatic cholangial drainage, liver biopsy, video-assisted thoracoscopic surgery, laparoscopic resection of colon cancer, colostomy apotheosis, and varicose vein surgery. On days 7, 14, and 30 after discharge, no postoperative complications were reported or infection of COVID-19 cases was reported. Conclusions. Using scientific and well-designed protocols, day surgery can ensure quality surgical care with while ensuring medical safety during the COVID-19 outbreak. These protocols may also be applied to other surgical departments in China.

Healthcare facilities in China are facing increasing demands as the country has the fastest aging populations in the world. Day surgery can be utilized to address some of these demands. Benefits of day surgery include shortened hospital stay, decreased risk of hospital-associated infections, and increased cost efficiency. We present a retrospective study of eight years of day surgery data from West China Hospital, one of the largest hospitals in China, with an emphasis on an examination of the growth in day surgeries. We examined patterns of utilization of day surgery versus inpatient surgery (including types of surgeries performed in the Day Surgery Center and the ratio of day surgery versus elective surgery), as well as unplanned readmission and return to inpatient department rates, and a comparison of average costs and length of stay for day surgery versus hospital surgery. Day surgery has a safe and cost-effective way to alleviate the soaring healthcare demands in West China. There is potential opportunity to further address the ever-increasing demands on the healthcare system in this area by performing more complex surgeries as day surgeries. This article presents an effective organizational protocol and proposes a reliable medical quality assurance system, which prioritizes safety of the growing day surgery program; furthermore, it describes the factors and lessons learned from the successful implementation of a day surgery system.

Temporomandibular joints (TMJs) constitute a pair of joints that connect the jawbone to the skull. TMJs are bilateral joints which work as one unit in conducting daily functions such as speaking, mastication, and other activities associated with the movement of the jaw. Issues associated with the TMJs may arise due to various factors—one such factor being the internal load on the TMJ. These issues may contribute to temporomandibular disorders (TMD). This study aims to evaluate the mandibular trajectories and the associated stress changes during the process of opening the mouth on the TMJs of an asymptomatic subject. The mouth opening motion was recorded by a motion capturing system using models of the mandible and maxilla constructed based on the computed tomography (CT). Two discs constructed based on magnetic resonance imaging (MRI). Finite element analysis was performed on the relative motion of the mandible to the maxilla and validated. The process modelled by these displacements provided less than 10% error in terms of deformation. The simulation results indicate that the lateral intermediate zone—the head and neck of the mandible—and the articular eminence sustained the most significant stresses during the mouth opening motion. The results also suggested that the stresses increase as the range of opening increases with the greatest von Mises stress, tensile, and compressive stress found at the position of maximal opening.
