Conclusion: The method of compound coenzyme for injection is feasible according to the proposed limit value. It is suggested that the quality standard of compound coenzyme for injection should be added with the examination of depressor substance.

Objective To explore the mechanism by which liraglutide modulated the differentiation of monocyte subsets in high glucose (HG) conditions.Methods Primary mouse splenocyte suspensions were cultured in HG conditions induced by IFN-γ in the presence or absence of liraglutide.The cells were harvested,co-incubated with antibodies,and analyzed on a BD FACS Calibur.Mononuclear cells (MNCs) were gated according to lower granularity and larger size by SSC and FSC.Monocytes (MCs) were defined as CD11b+MNC and divided into three subsets based on Ly6C expression:Ly6Clow,Ly6Cmid,and Ly6Chi.ROS production in Ly6C+ and Ly6C-MCs was detected by 2',7'-dichlorofluorescein-diacetate (DCFH-DA) staining and ROS-containing MCs were identified as DCF+ cells in both Ly6C+ and Ly6C-MCs.Results HG (15 mmol/L,25 mmol/L,35 mmol/L) dose-dependently increased Ly6Chi and Ly6Cmid MC differentiation and also enhanced the production of ROS in Ly6C+MCs.Liraglutide (100 U,200 U) dose-dependently inhibited HG-induced Ly6Chi and Ly6Cmid MC differentiation and also promoted the differentiation of Ly6Clow MCs.Moreover,liraglutide significantly inhibited HG-induced ROS production in Ly6C+ MCs.Conclusion Liraglutide treatment significantly inhibited inflammatory MC diferentiation induced by HG and also reduced ROS production in inflammatory MCs.

Infectious stones are produced by urease producing microorganisms, which have a fast generation rate, high recurrence and mortality rates, and are prone to complications related to infection. At present, the treatment of infectious stones includes surgical treatment and drug treatment, and the research on its treatment methods has become one of the hotspots in the field of urology. This article provides a review of the research progress in the treatment of infectious stones, with the aim of improving understanding of the treatment of infectious stones.

Inflammatory orofacial pain, in which substance P (SP) plays an important role, is closely related to the cross-talk between trigeminal ganglion (TG) neurons and satellite glial cells (SGCs). SGC activation is emerging as the key mechanism underlying inflammatory pain through different signalling mechanisms, including glial fibrillary acidic protein (GFAP) activation, phosphorylation of mitogen-activated protein kinase (MAPK) signalling pathways, and cytokine upregulation. However, in the TG, the mechanism underlying SP-mediated orofacial pain generated by SGCs is largely unknown. In this study, we investigated whether SP is involved in inflammatory orofacial pain by upregulating interleukin (IL)-1β and tumour necrosis factor (TNF)-α from SGCs, and we explored whether MAPK signalling pathways mediate the pain process. In the present study, complete Freund's adjuvant (CFA) was injected into the whisker pad of rats to induce an inflammatory model in vivo. SP was administered to SGC cultures in vitro to confirm the effect of SP. Facial expression analysis showed that pre-injection of L703,606 (an NK-1 receptor antagonist), U0126 (an inhibitor of MAPK/extracellular signal-regulated kinase [ERK] kinase [MEK] 1/2), and SB203580 (an inhibitor of P38) into the TG to induce targeted prevention of the activation of the NK-1 receptor and the phosphorylation of MAPKs significantly suppressed CFA-induced inflammatory allodynia. In addition, SP promoted SGC activation, which was proven by increased GFAP, p-MAPKs, IL-1β and TNF-α in SGCs under inflammatory conditions. Moreover, the increase in IL-1β and TNF-α was suppressed by L703, 606, U0126 and SB203580 in vivo and in vitro. These present findings suggested that SP, released from TG neurons, activated SGCs through the ERK1/2 and P38 pathways and promoted the production of IL-1β and TNF-α from SGCs, contributing to inflammatory orofacial pain associated with peripheral sensitization.

Nonalcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis and insulin resistance and there are currently no approved drugs for its treatment. Hyperactivation of mTOR complex 1 (mTORC1) and subsequent impairment of the transcription factor EB (TFEB)-mediated autophagy-lysosomal pathway (ALP) are implicated in the development of NAFLD. Accordingly, agents that augment hepatic TFEB transcriptional activity may have therapeutic potential against NAFLD. The objective of this study was to investigate the effects of nuciferine, a major active component from lotus leaf, on NAFLD and its underlying mechanism of action. Here we show that nuciferine activated ALP and alleviated steatosis, insulin resistance in the livers of NAFLD mice and palmitic acid-challenged hepatocytes in a TFEB-dependent manner. Mechanistic investigation revealed that nuciferine interacts with the Ragulator subunit hepatitis B X-interacting protein and impairs the interaction of the Ragulator complex with Rag GTPases, thereby suppressing lysosomal localization and activity of mTORC1, which activates TFEB-mediated ALP and further ameliorates hepatic steatosis and insulin resistance. Our present results indicate that nuciferine may be a potential agent for treating NAFLD and that regulation of the mTORC1-TFEB-ALP axis could represent a novel pharmacological strategy to combat NAFLD.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
