Objective To explore the feasibility and reference value of allogeneic lung transplantation and postoperative monitoring in miniature pigs for lung transplantation research. Methods Two miniature pigs (R1 and R2) underwent left lung allogeneic transplantation. Complement-dependent cytotoxicity tests and blood cross-matching were performed before surgery. The main operative times and partial pressure of arterial oxygen (PaO2) after opening the pulmonary artery were recorded during surgery. Postoperatively, routine blood tests, biochemical blood indicators and inflammatory factors were detected, and pathological examinations of multiple organs were conducted. Results The complement-dependent cytotoxicity test showed that the survival rate of lymphocytes between donors and recipients was 42.5%-47.3%, and no agglutination reaction occurred in the cross-matching. The first warm ischemia times of D1 and D2 were 17 min and 10 min, respectively, and the cold ischemia times were 246 min and 216 min, respectively. Ultimately, R1 and R2 survived for 1.5 h and 104 h, respectively. Postoperatively, in R1, albumin (ALB) and globulin (GLB) decreased, and alanine aminotransferase increased; in R2, ALB, GLB and aspartate aminotransferase all increased. Urea nitrogen and serum creatinine increased in both recipients. Pathological results showed that in R1, the transplanted lung had partial consolidation with inflammatory cell infiltration, and multiple organs were congested and damaged. In R2, the transplanted lung had severe necrosis with fibrosis, and multiple organs had mild to moderate damage. The expression levels of interleukin-1β and interleukin-6 increased in the transplanted lungs. Conclusions The allogeneic lung transplantation model in miniature pigs may systematically evaluate immunological compatibility, intraoperative function and postoperative organ damage. The data obtained may provide technical references for subsequent lung transplantation research.

OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets, followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established , and the zebrafish were treated with L. ruthenicum Murr. extract (LRME) at concentrations of 0.1, 0.2 and 0.4 mg/mL, respectively; 24 h later, behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 (IL-6), IL-1β, IL-10, tumor necrosis factor-α (TNF-α)], oxidative stress markers [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), catalase (CAT)], and neurotransmitters [5- hydroxytryptamine (5-HT), γ-aminobutyric acid (GABA), glutamic acid (Glu), dopamine (DA), and norepinephrine (NE)] were measured. The protein expression levels of protein kinase B1 (AKT1), phosphorylated AKT1 (p-AKT1), epidermal growth factor receptor (EGFR), B-cell lymphoma 2 (Bcl-2), sarcoma proto-oncogene,non-receptor tyrosine kinase (SRC), and heat shock protein 90α family class A member 1 (HSP90AA1) in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these, apigenin, naringenin and others were recognized as core active compounds, while AKT1, EGFR and others served as key targets; EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-, medium-, and high-dose groups were 54.60%, 69.03% and 77.97%, 开发。E-mail:hjp_yft@163.com respectively, while the inhibition ratios of locomotor distance were 0.57, 0.83 and 0.95, respectively. Compared with the model group, the number of resting counts, resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups (P<0.05). Neuronal damage in the brain was alleviated. Additionally, the levels of IL-6, IL-1β, TNF-α, MDA, Glu, DA and NE, as well as the protein expression levels of AKT1, p-AKT1, EGFR, SRC and HSP90AA1, were markedly reduced (P<0.05), while the levels of IL-10, SOD, GSH-Px, CAT, 5-HT and GABA, as well as Bcl-2 protein expression, were significantly elevated (P<0.05). CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects, and its specific mechanism may be related to the regulation of inflammatory responses, oxidative stress, neurotransmitter balance, and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

OBJECTIVE To analyze the safety and efficacy of vonoprazan (VPZ) in the treatment of peptic ulcer (PU) and post-endoscopic submucosal dissection (ESD) ulcers, providing evidence-based pharmaceutical evidence for clinical practice and medical decision-making. METHODS Retrieved from CNKI, Wanfang, VIP, CBM, PubMed, Embase, Web of Science, and the Cochrane Library, meta-analyses/systematic reviews related to VPZ in the treatment of PU and post-ESD ulcers were collected. Two researchers independently performed literature screening, data extraction, quality assessment of included studies, and evaluation of literature overlap. By employing the umbrella review analysis, a fresh meta-analysis was conducted on all relevant raw research data when a high degree of overlap was identified among the included studies. RESULTS A total of 17 meta-analyses were included, with quality ranging from high to very low; all outcome measures involved showed a very high level of overlap in the included meta-analyses (corrected covered area: 22.22%-100%). In the treatment of post-ESD ulcers, compared to proton pump inhibitor (PPI), VPZ significantly improved the ulcer healing rate at 4 weeks post-ESD [RR=1.27, 95%CI (1.03, 1.56), Z=2.21, P= 0.027] and the ulcer contraction rate post-ESD [MD=0.08, 95%CI (0.00, 0.16), Z=2.09, P=0.037], while significantly reducing the ulcer recurrence rate in patients with a history of PU [RR=0.49, 95%CI (0.32, 0.73), Z=3.49, P=0.001]; the delayed bleeding rate in the VPZ group was significantly lower than that in the lansoprazole subgroup [RR=0.47, 95%CI (0.25, 0.90), Z=2.28, P=0.02]. In the treatment of PU, the incidence of adverse events with VPZ was significantly higher than that with PPI in the duodenal ulcer subgroup [RR=1.13, 95%CI (1.02, 1.26), Z=2.38, P=0.017]. CONCLUSIONS For post-ESD ulcers, VPZ demonstrates superior therapeutic efficacy compared to PPI and can reduce ulcer recurrence rates in patients with a history of PU. However, it does not offer advantages in terms of safety for duodenal ulcer treatment.

ObjectiveTo study the mechanism of Yinchenhao Tang on the improvement of cholestatic liver injury (CLI) by inhibiting toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear transcription factor-κB (NF-κB) pathway via regulating farnesol X receptor (FXR). MethodsA total of 40 Wistar male rats were randomly selected, with 10 as a blank group,and the remaining rats were subjected to the CLI model induced by alpha-naphthalene isothiocyanate (ANIT). After modeling,they were randomly divided into the model group, the ursodeoxycholic acid (0.1 g·kg-1) group and the Yinchenhao Tang (9.23 g·kg-1) group,with 10 animals in each group. Each administration group was given the corresponding drug by intragastric administration for three consecutive days. Alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),γ-glutamyl transpeptidase (γ-GT),total bile acid (TBA),total bilirubin (TBil) and direct bilirubin (DBil) levels in serum were detected. Tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β),and interleukin-6 (IL-6) levels in liver tissue were detected. Real-time PCR was used to detect the mRNA expression of FXR,TLR4,MyD88,NF-κB,F4/80,TNF-α,IL-1β and IL-6 in liver tissue. Western blot was used to detect protein expression of FXR,TLR4,MyD88 and NF-κB in liver tissue. The histopathological changes of the liver were observed by hematoxylin-eosin (HE) staining. ResultsCompared with those in the blank group,ALT,AST,ALP,γ-GT,TBA,TBil and DBil levels in serum of rats in the model group were significantly increased (P<0.01). The levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were significantly increased (P<0.01),and the mRNA and protein expressions of FXR in liver tissue were decreased (P<0.01). The mRNA and protein expressions of TLR4,MyD88 and NF-κB and the mRNA expression of F4/80 were obviously increased (P<0.05,P<0.01). Hepatic histopathology showed inflammatory cell infiltration and proliferative changes of bile duct epithelial cells. Compared with those in the model group,ALT,ALP,γ-GT,TBA,TBil and DBil levels in serum of rats in the ursodeoxycholic acid group were obviously decreased (P<0.05,P<0.01),and the levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were obviously decreased (P<0.05,P<0.01). The mRNA and protein expressions of TLR4,MyD88 and NF-κB and the mRNA expression of F4/80 in liver tissue were obviously decreased (P<0.05,P<0.01). ALT,AST,ALP,γ-GT,TBA,TBil and DBil levels in the serum of rats in the Yinchenhao Tang group were obviously decreased (P<0.05,P<0.01),and the levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were obviously decreased (P<0.01). The mRNA and protein expressions of FXR in liver tissue were significantly increased,and the mRNA expressions of TLR4,MyD88,NF-κB,and F4/80, as well as the protein expressions of TLR4 and NF-κB were obviously decreased (P<0.05,P<0.01). The inflammatory cell infiltration of liver tissue and the proliferation of bile duct epithelial cells decreased. ConclusionYinchenhao Tang has an obvious protective effect on CLI,and its mechanism may be related to regulating FXR to inhibit TLR4/MyD88/NF-κB pathway-mediated inflammatory response.

ObjectiveTo establish a regional risk assessment system for hospital-acquired infections in neurosurgery department of general hospital, and to evaluate its prevention and control effectiveness. MethodsFailure mode and effect analysis (FMEA) was used to identify the core risk factors for infections in neurosurgery department. The risk priority number (RPN) of each risk factor was calculated to determine the priority intervention targets. Targeted interventions were developed and continuously refined through the plan-do-check-act (PDCA) cycles. Data from January to June 2023 (control group) and July to December 2023 (intervention group) were collected to compare the differences in environmental hygiene monitoring qualification rate, incidence rate of hospital-acquired infections among inpatients, and detection rate of bacterial antimicrobial resistance. ResultsHigh-risk factors for hospital-acquired infections in neurosurgery department included patient-related risk factors, inadequate implementation of isolation measures for special infections, and poor compliance with surgical site infection (SSI) prevention protocols. After intervention, the environmental hygiene qualification rate significantly increased from 81.55% to 100.00% (χ²=120.49, P<0.001). The overall hospital-acquired infection rate among inpatients decreased from 2.62% to 2.45%, the infection rate of per case declined from 3.12% to 2.84%, and the detection rate of multidrug-resistant organism infections reduced from 43.72% to 36.79%. Additionally, antimicrobial utilization rate decreased from 48.75% to 42.53% (χ²=34.09, P<0.001). ConclusionThe FMEA-based risk assessment system can effectively identify critical infection risks in neurosurgery department, and targeted interventions can significantly improve infection prevention and control performance.

Background Co-exposure to noise and microwave radiation occurs frequently. The central nervous system has been identified as a sensitive target organ for both noise and microwave exposure individually, and the underlying mechanisms remain poorly understood. The specific biological effects resulting from co-exposure to these two factors have yet to be fully elucidated. Objective To clarify the effects of co-exposure to noise and microwave on neurobehavior and hippocampal tissue structure, and to explore the underlying mechanism through the assessment of serum cytokines. Methods C57BL/6N mice were selected and randomly assigned to a blank control group, a noise group, a microwave group, and a combined noise & microwave exposure group. To establish the exposure models, the noise group was subjected to broadband noise at 100 dB for 2 h, while the microwave group received radiation at a central frequency of 9.375 GHz with an average power density of 12 mW·cm−2 and a specific absorption rate of 2.58 W·kg−1 for 15 min. Open field and tail suspension tests assessed anxiety-like emotional behaviour; novel object recognition and Y-maze tests evaluated cognitive function. Histological changes in hippocampal tissue were examined using haematoxylin and eosin (HE) staining, and Nissl staining under light microscopy. Serum cytokine levels were measured using radioimmunoassay and enzyme-linked immunosorbent assay (ELISA). Results After 3 d of exposure, the noise, microwave, and combined exposure groups showed significant reductions in exploration frequency, duration, and distance within the central zone of the open field test compared to the control group (P < 0.01); the combined exposure group exhibited increased ratios of peripheral-to-central exploration time and distance (P < 0.05). After 7 d of exposure, compared with the control group, the noise group maintained a decrease in central zone exploration time (P < 0.01), while the combined exposure group showed persistent decline across all central zone metrics (P < 0.05) and elevated peripheral-to-central ratios (P < 0.05); compared to the microwave group, the combined exposure group showed significant less time in the central zone (P < 0.05) and higher peripheral-to-central ratios (P < 0.05). Regarding behaviour and cognition, compared with the control group, the combined exposure group showed increased immobility time in the tail suspension test after 3 d of exposure (P < 0.01). At this interval, all exposure groups demonstrated reduced frequency and duration of novel object recognition (P < 0.05), with the combined exposure group showing a marked decrease in novel arm exploration time (P < 0.01). After 7 d of exposure, compared with the control group, the noise group showed reduced novel object recognition frequency (P < 0.05), and both the noise and microwave groups exhibited decreased novel arm exploration time (P < 0.05). Pathological alterations including an increased number of hyperchromatic nuclei and depleted Nissl bodies were observed in the CA3 and DG regions across all exposure groups with the most severe lesions observed in the combined exposure group. Serum levels of central nervous system-specific protein β (S-100β), glial fibrillary acidic protein (GFAP), and corticosterone (CORT) were significantly elevated in all exposure groups compared with the control group (P < 0.05). Aquaporin-4 (AQP4) levels increased in the combined exposure group (P < 0.05), while CXC chemokine ligand 10 (CXCL10) levels rose in both the noise and combined groups compared with the control group (P < 0.05). Specifically, S-100β and CXCL10 levels in the combined exposure group were higher than those in the microwave group (P < 0.05); moreover, levels of S-100β, GFAP, CORT, AQP4, and CXCL10 in the combined exposure group were significantly higher than those in the noise group (P < 0.05). Conclusion Combined exposure to noise and microwave radiation induces pathological changes in the hippocampus of mice, increases levels of serum stress hormones and neuro-specific biomarkers. These impairments are more severe than those observed following single-factor exposure. The underlaying mechanism may be related to systemic stress response, neuronal damage, astrocyte activation, and changes in blood-brain barrier permeability, leading to emotional behavioral abnormalities and cognitive decline.

ObjectiveTo investigate the mechanism of action of remifentanil (RMZL) in alleviating lung ischemia-reperfusion injury (LIRI) in rats by inhibiting pyroptosis through modulating hypoxia inducible factor-1α (HIF-1α)/NOD-like receptor thermal protein domain associated protein 3 (NLRP3) pathway. MethodsRats were stochastically assigned into Control group, LIRI group, RMZL low-dose group, RMZL medium-dose group, RMZL high-dose group, and RMZL high-dose+HIF-1α activator dimethyloxallyl glycine (DMOG) group, with 18 rats in each group. Rats in Control group only had their left pulmonary hilum free and did not undergo ischemia-reperfusion treatment. Except for the Control group, LIRI models were constructed in all other groups. Rats in LIRI group were intraperitoneally injected with an equal amount of physiological saline 15 minutes before constructing LIRI model; rats in Control group were intraperitoneally injected with an equal amount of physiological saline 15 minutes before freeing left pulmonary hilum; rats in other groups were intraperitoneally injected with corresponding dose of drug 15 minutes before constructing LIRI model. The wet/dry weight ratio of lungs was calculated. HE staining was used to study lung tissue pathology. Immunofluorescence staining was used to detect the relative fluorescence intensity of gasdermin D (GSDMD) and NLRP3 double positive cells in lung tissue. ELISA was used to detect interleukin-1β and IL-18 in lung tissue. Western blot was used to detect HIF-1α, NLRP3, cysteine-aspartic protease-1 (Cleaved caspase-1), and gasdermin D-N (GSDMD-N) proteins in lung tissue. ResultsCompared to the Control group, the LIRI group showed disordered alveolar structure, thickened alveolar septa, and abundant inflammatory cell infiltration in rats. The lung wet/dry weight ratio, relative fluorescence intensity of GSDMD and NLRP3 double positive cells in lung tissue, IL-1β, IL-18 levels, and HIF-1α, NLRP3, Cleaved caspase-1, and GSDMD-N proteins increased (P0.05). For the LIRI group, rats in the RMZL low, medium, and high-dose groups displayed attenuated alveolar septal thickening and reduced inflammatory cell infiltration. The lung wet/dry weight ratio, relative fluorescence intensity of GSDMD and NLRP3 double positive cells in lung tissue, IL-1β, IL-18 levels, and HIF-1α, NLRP3, Cleaved caspase-1, and GSDMD-N proteins declined, and the RMZL high-dose group showed the most prominent trend (P0.05). Compared with the RMZL high-dose group, rats in the RMZL high-dose+DMOG group exhibited thickened alveolar septa and more inflammatory cell infiltration, along with increased lung wet/dry weight ratio, relative fluorescence intensity of GSDMD and NLRP3 double positive cells in lung tissue, levels of IL-1β and IL-18, and protein expression of HIF-1α, NLRP3, Cleaved caspase-1, and GSDMD-N (P0.05). ConclusionRMZL may inhibit pyroptosis in LIRI rats by suppressing HIF-1α/NLRP3 pathway.

This paper comprehensively discusses on the potential neurobiological mechanisms of acupuncture in the treatment of tobacco dependence, focusing on three important aspects, including acupuncture's regulation of tobacco dependence behavior, effects of acupuncture on withdrawal syndrome, and the role of acupuncture in preventing relapse. It is found that acupuncture can inhibit drug-seeking behavior by regulating the reward pathway and related neurons, such as dopamine, thus modulating tobacco dependence behavior. It also alleviates withdrawal symptoms by improving the oral environment of smokers and reducing negative emotions after quitting. Furthermore, acupuncture can prevent relapse by decreasing brain network activity related to smoking cravings and improving cognitive brain functions like addiction memory. Currently, research on the specific neurobiological mechanism of acupuncture in treating tobacco dependence and the involved neural circuits is limited. Future research directions are proposed, including the evaluation of clinical effects, exploration of specific therapeutic mechanisms, investigation of brain pathology, and strengthening the exploration of brain functions. Additionally, combining modern technologies to clarify the neural circuits involved in acupuncture intervention will provide a basis for acupuncture treatment of tobacco addiction.

ObjectiveTo investigate the effect of laminin subunit α3 (LAMA3) on the epithelial-mesenchymal transition (EMT), invasion, and metastasis abilities of pancreatic cancer (PC). MethodsA comprehensive analysis was performed for tumor- and EMT-related databases to identify the EMT genes associated with PC, especially LAMA3. The methods of qRT-PCR and Western blot were used to measure the expression level of LAMA3 in PC tissue and cell lines; immunofluorescence assay was used to determine the localization of LAMA3 in PANC-1 cells; Transwell assay was used to investigate the effect of LAMA3 on the invasion and migration abilities of PC cells. The t-test was used for comparison of continuous data between groups. ResultsThe analysis of the TCGA database identified 3 EMT-related oncogenes for PC, i.e., LAMA3, AREG, and SDC1. The LASSO-Cox regression model showed that LAMA3 had the most significant impact on the prognosis of PC (risk score=0.256 1×LAMA3+0.043 1×SDC1+0.071 4×AREG). The Cox model and nomogram showed that the high expression of LAMA3 was an independent risk factor for the poor prognosis of PC (hazard ratio=1.32, 95% confidence interval: 1.07 — 1.62, P<0.01). Experimental results showed that there was a significant increase in the expression of LAMA3 in pancreatic cancer tissue compared with the normal pancreatic tissue. Compared with the HPDE cell line, there were varying degrees of increase in the expression of LAMA3 in pancreatic cancer AsPC-1, BxPC-3, PANC-1, MIA PaCa-2, and SW1990 cell lines, with the highest expression level in PANC-1 cells. The enrichment analysis showed that LAMA3 was associated with the biological processes and signaling pathways such as EMT, collagen metabolism, extracellular matrix degradation, the TGF-β pathway, and the PI3K pathway. After the knockdown of LAMA3, there were significant reductions in the expression levels of N-Cadherin, Vimentin, and Snail, while there was a significant increase in the expression level of E-Cadherin. Transwell assay showed that there were significant reductions in the invasion and migration abilities of PANC-1 cells after the knockdown of LAMA3. ConclusionLAMA3 is highly expressed in PC and can promote the EMT, invasion, and migration of PC cells, and therefore, LAMA3 may be used as a novel diagnostic marker and a new therapeutic target for PC.
