Local anesthetics (LAs), such as articaine (AT), exhibit limited efficacy in inflammatory environments, which constitutes a significant limitation in their clinical application within oral medicine. In our prior research, we developed AT-17, which demonstrated effective properties in chronic inflammatory conditions and appears to function as a novel oral LA that could address this challenge. In the present study, we further elucidated the beneficial effects of AT-17 in acute inflammation, particularly in oral acute inflammation, where mitochondrial-related apoptosis played a crucial role. Our findings indicated that AT-17 effectively inhibited lipopolysaccharide (LPS)-induced nerve cell apoptosis by ameliorating mitochondrial dysfunction in vitro. This process involved the inhibition of mitochondrial reactive oxygen species (mtROS) production and the subsequent activation of the NRF2 pathway. Most notably, improvements in mitochondria-related apoptosis were key contributors to AT-17's inhibition of voltage-gated sodium channels. Additionally, AT-17 was shown to reduce mtROS production in nerve cells through the Na⁺/NCLX/ETC signaling axis. In conclusion, we have developed a novel local anesthetic that exhibits pronounced anesthetic functionality under inflammatory conditions by enhancing mitochondria-related apoptosis. This advancement holds considerable promise for future drug development and deepening our understanding of the underlying mechanisms of action.

Porcine hemagglutinating encephalomyelitis virus(PHEV),a betacoronavirus with a sin-gle-stranded,positive-sense RNA genome,is an important pathogen in the swine industry.It causes porcine hemagglutinating encephalomyelitis(PHE),presenting with symptoms such as vomiting,diarrhea,neurological symptoms,and respiratory distress,particularly in piglets.The virus is asso-ciated with high mortality rates and growth stunting in subclinical cases.PHEV has a well-docu-mented global distribution,with occurrences reported across Europe,South America,North Amer-ica,and East Asia,posing a considerable challenge to the swine industry.This review aims to pro-vide a comprehensive overview of PHE's virological characteristics,epidemiology,clinical and pathological manifestations,mechanisms of infection and pathogenicity,and the current state of di-agnostic techniques.It further evaluates advancements in vaccine and antiviral development,along-side comprehensive prevention and control strategies,contextualized within the framework of the latest foundational research.

Lens injury is an important etiological factor in the reduction of visual function following ocular trauma.Currently, there are no clear standards for the classification of lens injury, and comprehensive diagnostic tools are lacking.This deficiency leads to numerous controversies and challenges in critical areas, such as diagnosis and preoperative evalution, timing of surgery, surgical strategy, and assessment of postoperative prognosis.Tomographic imaging technology, such as computed tomography, magnetic resonance imaging, optical coherence tomography, has introduced a new dimension to the evaluation of lens injury, which is crucial for assessing the transparency, texture, location, morphology, and integrity of the lens, as well as the zonules and nearby intraocular structures.However, the use of tomographic imaging technology is somewhat limited due to the limitations of relying on a single method.With the ongoing advancement of imaging technologies and the rapid development of big data and artificial intelligence, tomographic imaging will become an increasingly essential tool in the future management of lens injury.Our expert group reviewed the epidemiological characteristics and classification of lens injury and the major challenges currently faced in the diagnosis and treatment of lens injury, and provided expert recommendations mainly focusing on the application, shortcomings and limitations of current tomographic imaging technology in the diagnosis and treatment of lens injury, and future development directions.

Objectives:To explore the impact of intensive lipid-lowering strategy on short-term prognosis of acute coronary syndrome(ACS)patients with multi-vessel disease. Methods:A total of 136 ACS patients with multi-vessel disease who received coronary stenting at Zhongnan Hospital of Wuhan University from August 2019 to November 2020 were enrolled in this study.Patients were divided into intensive lipid-lowering group(control low density lipoprotein cholesterol[LDL-C]below 1.0 mmol/L within 3 months,and continuously meet the standards within 12 months,n=69)or standard lipid-lowering group(gradually control LDL-C below 1.4 mmol/L within one year,n=67).The total cholesterol(TC),triglycerides(TG),LDL-C,high-density lipoprotein cholesterol(HDL-C),and lipoprotein(a)(Lp[a])data were collected.Incidence of major adverse cardiovascular events(MACE,including cardiac death,myocardial infarction,target vessel revascularization and stroke)were observed during 12 months of follow up. Results:The baseline data of the intensive lipid-lowering group and the standard lipid-lowering group were consistent before intervention.At the timeline of enrollment,there was no statistically significant difference in the blood lipid profiles(including TC,TG,LDL-C,HDL-C)between the two groups.After 3-months,patients in the intensive lipid-lowering group experienced significantly lower TC,TG,LDL-C and Lp(a)compared with baseline values(all P<0.05),while HDL-C remained unchanged(P>0.05).The standard lipid-lowering group showed a significant decrease in TC and LDL-C compared with baseline values(both P<0.05).The TC and LDL-C levels were significantly lower in the intensive lipid-lowering group than in the standard lipid-lowering group at 3/6/12 months follow up after discharge(all P<0.01).At 12 months follow-up,Kaplan-Meier survival analysis showed that the incidence of MACE was significantly lower in the intensive lipid-lowering group than in the standard lipid-lowering group(2.90%vs.14.93%,χ2=6.090,P=0.014).Multiple Cox regression analysis revealed that the intensive lipid-lowering strategy significantly reduced the risk of MACE compared with the standard lipid-lowering strategy(HR=0.177,95%CI:0.037-0.838,P=0.029). Conclusions:Our data show that intensive lipid-lowering strategy may probably reduce the incidence of short-term MACE in ASC patients with multi-vessel disease.Large-scale prospective multi-center studies are needed to further validate these results.

Objective:To explore the current status of rumination in inpatients with metastatic prostate cancer (mPCa) under the disease coping mechanism, and analyzing its influencing factors.Methods:From March 2021 to December 2022, 267 mPCa inpatients at the Tenth People's Hospital of Tongji University were selected as the study subject using convenience sampling. The survey was conducted using the General Information Questionnaire, Chinese Version of Event Relate Rumination Inventory (C-ERI), Medical Coping Modes Questionnaire (MCMQ), International Prostate Symptom Score (IPSS), and Social Support Revalued Scale (SSRS), and the factors influencing the rumination in patients were analyzed.Results:This study collected 260 valid questionnaires, with an effective response rate of 97.4% (260/267). The total score of rumination in 260 mPCa patients was (31.08±6.46), with invasive rumination and purposeful rumination scores of (14.13±4.44) and (16.95±4.55), respectively. The initial prostate-specific antigen index, confrontation medical coping modes were the influencing factors of invasive rumination in mPCa patients ( P<0.05). The initial prostate-specific antigen index, course of disease, social support, and confrontation medical coping style were the influencing factors of purposeful rumination in mPCa patients ( P<0.05) . Conclusions:The rumination of mPCa patients is above the medium level, and is influenced by multiple factors under the disease coping mechanism. Clinical medical and nursing staff should combine the clinical situation and characteristics of mPCa patients, provide personalized interventions as early as possible, and assist patients in improving their positive cognitive processing abilities.

Objective:To investigate the feasibility and efficacy of transcystic injection of indocyanine green during laparoscopic cholecystectomy (LC) surgery in the treatment of patients with gallbladder stones combined with liver cirrhosis.Methods:The clinical data of 96 patients with cirrhosis who underwent LC for gallbladder stones with cholecystitis attacks in the Department of Hepatobiliary and Pancreatic Surgery of the Second People′s Hospital of Changzhou City from January 2018 to May 2022 were retrospectively analyzed. All patients were diagnosed by clinical history and auxiliary examination before surgery and underwent cholecystectomy according to their groups, which were divided into fluorescence group ( n=49) and white light group ( n=47) according to whether ICG was used or not, where the fluorescence group underwent LC in fluorescence mode after direct intraoperative injection of ICG via gallbladder. The two groups were compared in terms of identification time of the three tubes, operation time, intraoperative bleeding, intraoperative injury, intraoperative open abdomen and blood transfusion, postoperative drainage time, postoperative hospitalization time, postoperative complications and changes in infection and liver function indexes before and after surgery. The measurement data obeying normal distribution were expressed as mean±standard deviation( ± s), and independent sample t-test was used for comparison between groups. The measurement data obeying the skewed distribution were expressed by M( Q1, Q3), and the Mann-Whitney U test was used for comparison between groups. Count data were expressed as rates (%), and the chi-square test or Fisher′s exact probability method was used for comparison between groups. Results:The procedure was successfully performed in both groups, and the identification of triple-tube time, operative time, intraoperative bleeding, postoperative drainage time, postoperative hospital stay, postoperative ALT, postoperative GGT, and postoperative TBIL in the fluorescent group were (14.96±1.49) min, (52.14±7.36) min, 5(5, 10) mL, (1.61±0.61) d, (2.37±0.49) d, 31.5(22.0, 44.8) U/L, 38.0(21.0, 91.5) U/L, 18.0(11.5, 22.8) μmol/L, and (29.87±3.37) min, (84.36±13.25) min, 10(10, 20) mL, (2.70±0.69) d, (3.15±0.42) d, 45.0(28.0, 64.8) U/L, 73.0(32.0, 132.0) U/L, 23.0(16.1, 29.3) μmol/L in the white light group and the differences were statistically significant compared with the two groups( P<0.05). In the fluorescence group, there was no intraoperative injury and no cases of intraoperative opening, and there were 2 cases of postoperative complications, while in the white light group, there were 2 cases of intraoperative injury, 1 case of intraoperative opening, and 5 cases of postoperative complications, and there were no cases of blood transfusion in both groups. There was no statistically significant difference between the fluorescence group and the white light group when comparing the preoperative laboratory indexes of both groups ( P>0.05). When comparing the first postoperative white blood cell count, C-reactive protein, aspartate aminotransferase, and alkaline phosphatase indexes in the fluorescence group and the white light group, there was no statistically significant difference between the two groups ( P>0.05). Conclusion:When LC is performed in patients with symptomatic gallbladder stones combined with cirrhosis, intraoperative injection of indocyanine green via the gallbladder to visualize the gallbladder and bile duct structures is simple and easy to perform, and the safe and efficient dissection of extrahepatic bile ducts and gallbladder bed speeds up the procedure while reducing postoperative trauma.
