Objective: To investigate the distribution of pathogenic bacteria in the patients of injuries combined with infection after May 12 Wenchuan Earthquake and the drug resistance thereof.
Methods: Bacterial culture and identification were conducted on 139 clinical specimens from 108 patients with open injuries combined with infection. Drug-sensitive test was carried out by Kirby-Bauer method on the isolated strains.
Results: Ninety-six stains were isolated, 79.86% of them were from the infected wound secretion and 58.33% were from three department of orthopedics. The bacteria with high isolation rates included Acinetobacter spp. (20 strains), Enterobacter cloacae (20 strains), Escherichia coli (17 strains), and Staphylococcus spp. (13 strains). The isolated Gram negative bacteria showed lower resistance to imipenem, amikacin, and cefoperazone/sulbactam.
Conclusion: The Gram negative bacteria isolated from the wounds caused by earthquake show lower resistance to imipenem, amikacin, and cefoperazone/sulbactam. No Staphylococcus spp. is found resistant to glycopeptides.

Background: The amyloid cascade hypothesis still dominates in Alzheimer's disease (AD), and the acceleration of the clearance efficiency of amyloid-β (Aβ) has been always considered as an effective treatment option to slow the occurrence and progression of AD.
Objective: This study aims to explore the role of zkscan3 and its related pathways in AD of the microglia-mediated pathogenesis, and whether the combined effect of drugs can exert neuroprotective function.
Methods: N9 mouse microglia and HT-22 mouse hippocampal neurons were randomly divided into 6 groups, qRT-PCR technique was used to detect the gene expression level of zkscan3 and the genes related to lysosome generation and function.

Cervical dilatation, uterine evacuation, and curettage (D&E&C) are common gynecological procedures for abortion, yet they carry risks of complications such as uterine perforation and intra-abdominal organ incarceration. Here, we report a rare case of a breastfeeding patient who had an embedded abdominal greater omentum in the anterior wall of the uterus and into the uterine cavity during D&E&C. We used combined hysteroscopic and laparoscopic treatment for this case and successfully removed the embedded greater omentum.

Falling is an emergency situation that can result in serious injury or even death, especially in the absence of immediate assistance. Therefore, developing a model that can accurately and promptly detect falls is crucial for enhancing quality of life and safety. In the field of object detection, while YOLOv8 has recently made notable strides in detection accuracy and speed, it still faces challenges in detecting falls due to variations in lighting, occlusions, and complex human postures.

Background: Fractures of the thoracic and lumbar spine are increasingly common. Although it is known that such fractures may elevate the risk of near-term morbidity, the natural history of patients who sustain such injuries remains poorly described. We sought to characterize the natural history of patients treated for thoracolumbar fractures and to understand clinical and sociodemographic factors associated with survival.

Aligned electrospinning membranes (Align) have demonstrated the potential to enhance wound healing by establishing a regenerative microenvironment surrounding the wound; However, the precise mechanism underlying its facilitation of healing remains unclear. To elucidate aligned electrospun fiber membrane's role in accelerating wound healing and improving its quality, we conducted a comprehensive analysis. Firstly, in vivo experiments confirmed that Align promotes wound healing.
