Background: In China, several measures have been adopted to decrease unnecessary antimicrobial overuse since 2010. This study aimed to identify characteristics of antimicrobial use in Chinese hospitals after implementing these measures and to explore additional targets for future antimicrobial stewardship.
Methods: In 2012, point prevalence surveys conducted in Chinese hospitals included inpatients who were admitted for at least 24 hours. Details regarding infection, antimicrobial use, and bacterial cultures were recorded.
Results: A survey of 786,028 inpatients in 1,313 hospitals included prevalence of health care-associated (3.22%) and community-acquired infections (22.52%); antimicrobial use prevalence (AUP, 38.39%); bacterial culture rate (BCR, 40.16%); and proportions of administration of a single antimicrobial (75.33%), therapeutic (23.16%), prophylactic (11.99%), and therapeutic plus prophylactic (3.24%) AUP rates. Prophylactic AUP rates of hospitals with <300, 300-599, 600-899, and ≥900 beds were 14.23%, 12.45%, 11.45%, and 11.34%, respectively. However, BCRs increased with increasing hospital bed numbers. AUP rates for surgical patients with classes I, II, and III wounds were 45.19%, 68.18%, and 68.47%, respectively. Prophylactic AUP rates for surgical patients decreased with increasing hospital bed numbers. These indices varied among different hospital departments.
Conclusion: More efforts are needed toward small hospitals, prophylactic antimicrobial use for surgical patients, and departments with low BCRs to optimize the clinical antimicrobial use.

Background: The dynein cytoplasmic two heavy chain 1 (DYNC2H1) gene encodes a cytoplasmic dynein subunit. Cytoplasmic dyneins transport cargo towards the minus end of microtubules and are thus termed the "retrograde" cellular motor. Mutations in DYNC2H1 are the main causative mutations of short rib-thoracic dysplasia syndrome type III with or without polydactyly (SRTD3).

Background: Carotid atherosclerotic plaque is the primary cause of cardiovascular and cerebrovascular diseases. It is closely related to oxidative stress and immune inflammation. This bioinformatic study was conducted to identify key oxidative stress-related genes and key immune cell infiltration involved in the formation, progression, and stabilization of plaques and investigate the relationship between them.

Background: Closed head injury (CHI) provokes a prominent neuroinflammation that may lead to long-term health consequences. Microglia plays pivotal and complex roles in neuroinflammation-mediated neuronal insult and repair following CHI. We previously reported that induced neural stem cells (iNSCs) can block the effects of CXCL12/CXCR4 signaling on NF-κB activation in activated microglia by CXCR4 overexpression.

The tendon-bone interface, known as the tenosynovial union or attachment, can be easily damaged by excessive exercise or trauma. Tendon-bone healing is a significant research topic in orthopedics, encompassing various aspects of sports injuries and postoperative recovery. Surgery is the most common treatment; however, it has limited efficacy in promoting tendon-bone healing and carries a risk of postoperative recurrence, necessitating the search for more effective treatments.

Background: The endoplasmic reticulum stress (ER stress) has been involved in various musculoskeletal disorders including non-traumatic osteonecrosis of femoral head (NT-ONFH).
Objective: The current study aimed to investigate the association of glucose-regulated protein 78 (GRP78) as well as CCAAT/enhancer-binding protein homologous protein (CHOP) expressions in serum and femoral head (FH) tissues with NT-ONFH's severity.
Methods: We enrolled NT-ONFH patients (n = 150) alongside healthy controls (HCs, n = 150).
