Objective To investigate the effectiveness and safety of acetaminophen combined with ketorolac tromethamine in pain management early after laparoscopic cholecystectomy(LC).Methods Ninety patients with LC under general anesthesia,42 males and 48 females,aged 18-78 years,BMI 18-28 kg/m2,ASA physical statusⅠorⅡ,were selected and randomly divided into two groups by random num-ber table method:the acetaminophen combined with ketorolac tromethamine group(group AK)and the nal-buphine group(group NA),45 patients in each group.Group AK received 500 mg(diluted to 50 ml)of acetaminophen injection and 30 mg of ketorolac tromethamine(diluted to 10 ml)injection pumped 15 mi-nutes before induction of anesthesia,and group NA received 50 ml of NS injection and 0.2 mg/kg of nalbu-phine(diluted to 10 ml)injection pumped at the same time.Postoperative pain was recorded 0.5,3,6,12,and 24 hours after surgery using VAS pain scores(the non-inferiority boundary Δ = 1.0 score).The sleep quality score on the night of surgery,the number of remedial analgesia cases within 24 hours after sur-gery,the Ramsay sedation score 0.5,3,and 6 hours after surgery,the occurrence of adverse reactions such as nausea and vomiting within 24 hours after surgery,and the overall satisfaction of patients were recorded.Results Compared with group NA,the VAS pain scores 0.5 hour after surgery was reduced in group AK(P＜0.05).The sleep quality score and overall satisfaction in group AK were significantly higher than those in group NA(P＜0.05).There were no significant differences in the rate of remedial analgesia,the score of Ramsay sedation at different time points and the incidence of nausea and vomiting within 24 hours after surgery between the two groups.Conclusion Acetaminophen combined with ketorolac tromethamine is not less effective than nalbuphine in relieving early postoperative pain after laparoscopic cholecystectomy without increasing the incidence of nausea and vomiting.Patients receiving acetaminophen combined with ketorolac tromethamine have higher sleep quality scores on the night of surgery and overall satisfaction.

Mitophagy, a highly precise form of autophagy, plays a pivotal role in maintaining cellular homeostasis by selectively targeting and eliminating damaged mitochondria through a process known as mitophagy. Within this tightly regulated mechanism, dysfunctional mitochondria are specifically delivered to lysosomes for degradation. Disruptions in mitophagy have been implicated in a diverse range of pathological conditions, spanning diseases of the nervous system, cardiovascular system, cancer, aging, and metabolic syndrome. The elucidation of mitophagy’s impact on cardiovascular disorders, liver diseases, metabolic syndromes, immune dysfunctions, inflammatory conditions, and cancer has significantly advanced our understanding of the complex pathogenesis underlying these conditions. These studies have shed light on the intricate connections between dysfunctional mitophagy and disease progression. Among the disorders associated with mitochondrial dysfunction, insulin resistance (IR) stands out as a prominent condition linked to metabolic disorders. IR is characterized by a diminished response to normal levels of insulin, necessitating higher insulin levels to trigger a typical physiological reaction. Hyperinsulinemia and metabolic disturbances often coexist with IR, primarily due to defects in insulin signal transduction. Oxidative stress, stemming from mitochondrial dysfunction, exerts dual effects in the context of IR. Initially, it disrupts insulin signaling pathways and subtly contributes to the development of IR. Additionally, by inducing mitochondrial damage and autophagy, oxidative stress indirectly impedes insulin signaling pathways. Consequently, mitophagy acts as a protective mechanism, encapsulating damaged or dysfunctional mitochondria through the autophagy-lysosome pathway. This efficient process eliminates excessive oxidative stress reactive. The intricate interplay between mitochondrial function, oxidative stress, mitophagy, and IR represents a captivating field of investigation in the realm of metabolic disorders. By unraveling the underlying complexities and comprehending the intricate relationships between these intertwined processes, researchers strive toward uncovering novel therapeutic strategies. With a particular focus on mitochondrial quality control and the maintenance of redox homeostasis, these interventions hold tremendous potential in mitigating IR and enhancing overall metabolic health. Emerging evidence from a myriad of studies has shed light on the active involvement of mitophagy in the pathogenesis of metabolic disorders. Notably, interventions such as exercise, drug therapies, and natural products have been documented to induce mitophagy, thereby exerting beneficial effects on metabolic health through the activation of diverse signaling pathways. Several pivotal signaling molecules, including AMPK, PINK1/Parkin, BNIP3/Nix, and FUNDC1, have been identified as key regulators of mitophagy and have been implicated in the favorable outcomes observed in metabolic disorders. Of particular interest is the unique role of PINK1/Parkin in mitophagy compared to other proteins involved in this process. PINK1/Parkin exerts influence on mitophagy through the ubiquitination of outer mitochondrial membrane proteins. Conversely, BNIP3/Nix and FUNDC1 modulate mitophagy through their interaction with LC3, while also displaying certain interrelationships with each other. In this comprehensive review, our objective is to investigate the intricate interplay between mitophagy and IR, elucidating the relevant signaling pathways and exploring the treatment strategies that have garnered attention in recent years. By assimilating and integrating these findings, we aim to establish a comprehensive understanding of the multifaceted roles and intricate mechanisms by which mitophagy influences IR. This endeavor, in turn, seeks to provide novel insights and serve as a catalyst for further research in the pursuit of innovative treatments targeting IR.

AIM:To investigate the relationship between the dynamic changes of Lymphocyte-to-monocytes ratios(LMR)before PD-1 inhibitor treat-ment and the efficacy and prognosis of PD-1 inhibi-tor treatment in patients with advanced non-small cell lung cancer(NSCLC).METHODS:The clinical case data of 83 patients with advanced non-small cell lung cancer admitted to the Cancer Hospital of Wuhu Second People's Hospital from June 2019 to July 2022 were retrospectively analyzed.The rou-tine blood LMR values of all patients before and af-ter treatment were collected,the cut-off value was calculated according to the ROC curve,and the LMR was divided into two groups:high and low be-fore treatment and after treatment.The differenc-es of ORR,DCR,PFS and OS among the patients in each group were analyzed and compared,and the value of LMR value and dynamic changes after treatment on the efficacy and prognosis of patients with PD-1 inhibitors in the treatment of NSCLC pa-tients was analyzed.RESULTS:According to the ROC curve,the critical value of LMR was 1.8,and the LMR was divided into the low LMR group at baseline(LMRB/S<1.8),the high LMR group at base-line(LMRB/S≥1.8)and the low LMR group after treatment(LMRafter<1.8)and the high LMR group af-ter treatment(LMRafter≥1.8).The ORR and DCR after immunotherapy in the high LMRB/S group were high-er than those in the low LMRB/S group(P=0.037;P= 0.0025).Among the patients with low LMRB/S be-fore treatment,the DCR of the LMRafter≥1.8 group was better than that of the LMRafter<1.8 group after treatment(P=0.005).Among the patients with high LMR before treatment,the DCR of the LMRafter≥1.8 group was better than that of the LMRafter<1.8 group(P=0.034).Kaplan-Meier analysis showed that PFS and OS were longer in the high LMRB/S group than in the low LMRB/S group before treat-ment.In the low LMRB/S group before treatment,PFS and OS were longer in patients with LMRafter≥1.8 than those with LMRafter<1.8(P=0.047;P=0.007).Multivariate Cox regression model analysis showed that high LMRB/S value before treatment was an in-dependent risk factor for PFS and OS in NSCLC pa-tients(P=0.006;P=0.033).CONCLUSION:High LMR value of patients before immunotherapy may im-prove the efficacy of PD-1 inhibitors,improve the prognosis of patients,and prolong the survival time.Moreover,the increase of LMR value after treatment may increase the efficacy of patients with low LMR before treatment and improve the prognosis of patients.

Objective:To explore the mechanism of miR-30e-5p inhibiting the invasion and migration of hepatoma cells by targeting phosphoinositide-3-kinase catalytic delta polypeptide(PIK3CD)-mediated phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)/mammalian target of the rapamycin(mTOR)signaling pathway.Methods:HepG2 cells were divided into control group,miR-30e-5p mimics group,PIK3CD knockdown group,negative control group,and miR-30e-5p mimics+PIK3CD overexpression group by transfecting the corresponding plasmids,the expression of miR-30e-5p,PIK3CD and PI3K/AKT/mTOR signaling pathway was detected by qRT-PCR and Western blot;the proliferation rate of Hep G2 cells in each group was detected by CCK-8 method;cell migration and invasion were measured by cell scratch test and Transwell test;the expression of matrix metalloproteinase(MMP)2,MMP9,E-cadherin,N-cadherin,Vimentin in Hep G2 cells of each group were detected by Western blot.The targeting regulation of miR-30e-5p on PIK3CD in Hep G2 cells was detected by double luciferase report assay.Results:Compared with the control group,the proliferation rate,migration rate,invasion number,the expression of N-cadherin,MMP2 and MMP9 proteins,the expression of PIK3CD protein and mRNA,p-P13K/PI3K,p-AKT/AKT,and p-mTOR/mTOR in the miR-30e-5p mimics group and PIK3CD knockdown group were lower(P＜0.05),the expression of E-cadherin protein was higher(P＜0.05).Overexpression of PIK3CD attenuates the inhibitory effects of miR-30e-5p mimics on proliferation,migration and invasion of hepatocellular carcinoma cells and elevates the expression of PI3K/AKT/mTOR pathway-related proteins;miR-30e-5p targets down-regulation of PIK3CD expression.Conclusion:Up-regulation of miR-30e-5p can prevent PI3K/AKT/mTOR signal activation by decreasing the expression of PIK3CD,thereby inhibiting the proliferation,migration and invasion of hepatocellular carcinoma cells.

Gallbladder carcinoma,a relatively rare malignancy within the biliary tract,presents a grave prognosis primarily due to asymptomatic early stages leading to advanced stage diagnosis and the absence of efficacious treatment options.Research has identified chronic inflammation,predom-inantly caused by gallstones,as a critical etiological factor.While surgical intervention offers potential curative outcomes in early stages,the majority of cases are identified too late for optimal surgical outcomes.Chemotherapy and targeted therapy,despite offering new therapeutic avenues,have not significantly improved overall survival rates.Thus,understanding the pathogenesis of gallbladder cancer,especially its association with key genetic and molecular pathways,is imperative for devising novel therapeutic strategies.This review delineates the epidemiology,pathogenesis,current treat-ment modalities,and research advancements in gallbladder cancer,aiming to provide innovative in-sights for clinical management and guide future research endeavors.

Non-small cell lung cancer (NSCLC) is one of the most common types of cancer in the world and is an important cause for cancer death. Although the application of immunotherapy in recent years has greatly improved the prognosis of NSCLC, there are still huge challenges in the treatment of NSCLC. The immune microenvironment plays an important role in the process of NSCLC development, infiltration and metastasis, and they can interact and influence each other, forming a vicious circle. Notably, single-cell RNA sequencing enables high-resolution analysis of individual cells and is of great value in revealing cell types, cell evolution trajectories, molecular mechanisms of cell differentiation, and intercellular regulation within the immune microenvironment. Single-cell RNA sequencing is expected to uncover more promising immunotherapies. This article reviews the important researches and latest achievements of single-cell RNA sequencing in the immune microenvironment of NSCLC, and aims to explore the significance of applying single-cell RNA sequencing to analyze the immune microenvironment of NSCLC.

Objective To compare the short-term clinical effects of Da Vinci robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in the treatment of posterior mediastinal tumors, and to explore the advantages of RATS posterior mediastinal tumor resection. Methods The clinical data of patients who underwent posterior mediastinal tumors resection through the lateral chest approach admitted to the same medical group in the Department of Thoracic Surgery of the First Hospital of Lanzhou University between January 2019 to January 2023 were retrospectively analyzed. According to the different surgical methods, the patients were divided into a RATS group and a VATS group. The clinical data were compared between the two groups. Results A total of 85 patients were included in this study. There were 39 patients in the RATS group, including 25 females and 14 males, with an average age of 47.6±13.0 years, and 46 patients in the VATS group, including 14 males and 32 females, with an average age of 45.3±14.7 years. All patients completed the operation successfully. The hospitalization cost in the RATS group was significantly higher than that in the VATS group (P<0.001), and the white blood cell count and neutrophilic granulocyte percentage on the first day after operation in the RATS group were lower than those in the VATS group, and the differences were statistically significant (P<0.05). The operative time, intraoperative bleeding, postoperative hospital stay, white blood cell count and neutrophil percentage on the third postoperative day, visual analogue scale score on the first and third postoperative days, duration of analgesic pump use, postoperative 12 h oxygen saturation (no oxygen inhalation), postoperative down bed time, total thoracic drainage volume, duration of drainage tube retention, and postoperative complication rates were not statistically different between the two groups (P>0.05). There was no perioperative death, conversion to thoracotomy or serious perioperative complications in both groups. Conclusion RATS resection of posterior mediastinal tumor via lateral thoracic approach is safe and feasible, and its short-term effect is similar to that of VATS via lateral thoracic single-hole approach. It is worth further comparative study to explore its benefit and cost performance.

Objective: To identify the social ecological factors of individual, family, and physical environments for affecting the development of fundamental motor skills (FMS) among overweight and obese children, so as to provide a basis for the future intervention design and policy making. Methods: From March to April 2022, one public primary school was recruited from each of the 4 main urban areas in Shijiazhuang, and a total of 425 children in schools were recruited for data collection including individual, family, physical environmental factors, by using a stratified cluster random sampling approach. Test of Gross Motor Development-Third Edition (TGMD-3) was used to evaluate children s FMS. Hierarchical linear regression model was employed to analysis the associations between the 18 factors for individual, family, and physical environments, and the FMS of overweight and obese children. Results: Individual level including the child s age, gender and sleep duration, and family level including high family economic level, parental support for physical activity, and the physical activity environment surrounding the family and community were consistent predictors of movement skills ( B =0.422, -1.972, 0.014, 0.045, 1.042, 0.827, 1.898), ball skills ( B =0.858, 3.953, 0.013, 0.092, 2.141, 1.173, 1.954), and composite skills ( B =1.305, 1.915, 0.028, 0.142, 3.091, 1.962, 3.879) among overweight and obese children ( P <0.05). Furthermore, child s body mass index (BMI), moderate to vigorous physical activity, perceived motor competence, pleasure of exercise,as well as BMI and physical activity levels of their primary caregiver, were associated with different types of FMS ( P <0.05). Individual, family, and physical environmental factors had moderate to high predictive explanatory power for FMS among overweight and obese children ( 2=0.69, 0.75, 0.93, P <0.01). Conclusions The factors influencing the development of FMS in overweight and obese children are multifaceted, with individual, family, and physical environment factors all playing significant roles.Corresponding measures should be actively taken to improve FMS in overweight and obese children.
