Objective To investigate the current status of work readiness and its influencing factors among patients returning to work after lung cancer surgery. Methods A retrospective study was conducted on young and middle-aged postoperative lung cancer patients who were treated at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to September 2023 and returned to their jobs. Data were collected through a general information questionnaire, readiness for return-to-work scale (RRTW), general self-efficacy scale (GSES), and simplified coping style questionnaire (SCSQ). Univariate and multivariate logistic regression analyses were used to explore the factors affecting the work readiness of patients returning to work. Results A total of 219 patients were included, with 59 males and 160 females aged 18-60 years. Among the postoperative lung cancer patients returning to work, 73.1% were in the active maintenance stage of return-to-work readiness with a RRTW score of (17.59±1.48) points, and 26.9% were in the uncertain maintenance stage with a RRTW score of (16.22±1.50) points. Multivariate logistic regression analysis showed that patients aged≤30 years (OR=52.381), employees of enterprises and institutions (OR=7.682), agricultural, pastoral, fishery, forestry laborers (OR=15.665), positive coping (OR=5.043), those with higher self-efficacy (OR=1.157) and engaged in physically demanding work (OR=2.449) had higher return-to-work readiness, while patients with≥2 children (OR=0.055), self-payment (OR=0.044), and those working more than 40 hours per week (OR=0.122) had lower return-to-work readiness. Conclusion The return-to-work readiness of young and middle-aged postoperative lung cancer patients needs to be improved, and occupation, job nature, main coping styles, general self-efficacy and other factors are associated with return-to-work readiness.

Objective To evaluate the clinical efficacy of transumbilical extracorporeal laparoscopic-assisted appendectomy(TUELAA)for pediatric uncomplicated appendicitis.Methods A retrospective analysis was conducted on 38 cases treated with TUELAA between January2019 and October2024.The median age was7.5 years old(range,2.4-16.3 years old).The duration of abdominal pain before admission was(20.6±10.6)h.Preoperative ultrasound revealed an average appendiceal diameter of(0.92±0.15)cm,with appendicoliths identified in15 cases.A vertical umbilical incision approximately1.5 cm in length was made,through which a 5 mm trocar(15 cm in length)with a 30° laparoscope and a 5 mm short trocar(9 cm in length)with grasping forceps were inserted.The abdominal cavity was explored,adhesions were dissected,and the appendiceal tip was grasped.The tissue between the two trocars was incised,and the appendix was extracted through the umbilical incision for extracorporeal ligation and excision.Results Among the 38 cases,31 had no significant adhesions around the appendix,and the appendectomy was successfully performed with smooth extraction of the appendix.In the remaining 7 cases with adhesions around the appendix,blunt laparoscopic dissection was used to release the adhesions.After the appendix tip was freed,it was extracted through the umbilical incision for complete excision.The surgical time was(27.1±8.6)min,and the postoperative hospitalization was1-3 d.Pathological diagnoses revealed32 cases of acute suppurative appendicitis and 6 cases of gangrenous appendicitis.No intravenous analgesics were used postoperatively.No discomfort such as abdominal pain was noted during telephone follow-ups for 2-68 months(median,58 months).Conclusion TUELAA demonstrates definite efficacy and favorable cosmetic outcomes for the treatment of pediatric uncomplicated appendicitis.

Organophosphorus nerve agents are the most threatening chemical warfare agents and terrorist agents.The number of nerve agents and their related chemicals involved in the verification of Chemical Weapon Convention(CWC)exceeds ten million,with the majority being isomers.Accurate structural identification of these chemicals has always been one of the challenges in CWC related verification analysis.In this work,a total of 17 kinds of alkyl phosphonate isomers and structural analogs from 5 groups were designed and synthesized,and then analyzed by gas chromatography-mass spectrometry(GC-MS)and gas chromatography-infrared spectroscopy(GC-FTIR).The spectra of isomers or structural analogs obtained from two techniques as well as the structural information provided therein were compared and analyzed.The results showed that for isomers or structural analogs with similar MS spectra,FTIR spectra could provided more structural fingerprint information of compounds and had advantages in confirming structures.Combined with the excellent separation ability of GC,GC-FTIR can be used to assist GC-MS in the structural confirmation of alkyl phosphates,achieving rapid and accurate identification of isomers or structural analogues.

6-Thioguanine(6-TG)is an antineoplastic agent used in treatment of acute leukemia.However,significant interindividual variability in dosing regimens and frequent clinical manifestations of hepatotoxicity and myelosuppression as adverse effects have affected its therapeutic efficacy.Consequently,the development of rapid analytical methods for 6-TG in clinical samples,enabling continuous therapeutic drug monitoring of plasma concentrations,holds substantial significance in optimizing dosage regimens,mitigating adverse reactions,and investigating drug metabolism mechanisms.In this study,multi-tipped gold nanostars(AuNSs)were prepared.With bis-(p-sulfonylphenyl)phenylphosphine molecule as the protecting agent and internal standard molecule,the AuNSs were assembled onto a highly sensitive surface-enhanced Raman(SERS)substrate for developing a ratio-based SERS quantitative analysis method for 6-TG in serum.The AuNSs containing multiple tips and gaps exhibited strong local surface plasmon resonance effect and SERS activity,ensuring the sensitivity of the analytical method.Furthermore,the introduction of internal standard molecules could improve the reproducibility,which guaranteed this method suitable for rapid analysis of drug molecules in complex samples.Quantitative analysis of 6-TG was achieved with linear detetion range of 1.0×10?4-1.0 mmol/L.In the spiked recovery experiments of serum,the RSD was less than 5.32%,and the recoveries were 94%-104%,which proved that this method could be used for rapid quantitative determination of 6-TG in serum.This method provided a powerful tool for studying drug pharmacokinetics,which could promote the optimization of the usage methods of anti-cancer drugs,and it was expected to further enhance the clinical efficacy and safety of 6-TG,enabling it to achieve the best therapeutic effect.

Objective To investigate the changes and clinical significance of pyroptosis and inflammation in children with acute lymphoblastic leukemia after chemotherapy.Methods A retrospective analysis was con-ducted on the clinical data of 98 children with acute lymphoblastic leukemia who received chemotherapy in the pediatrics and hematology and oncology departments of the hospital from May 2023 to August 2024.Accord-ing to the results of blood culture,the selected children were divided into the Gram-positive bacteria group,the Gram-negative bacteria group,the fungal group and the non-bloodstream infection group,and drug sensitivity tests were conducted.After chemotherapy,the children were divided into the granulocytosis group and the non-granulocytosis group according to the granulocyte level.The relevant indicators were detected and com-pared by methods such as blood routine,flow microsphere array technology,enzyme-linked immunosorbent assay(ELISA),and Western blot.Results After chemotherapy,the pyroptosis related indicators caspase-1,caspase-4,caspase-5,caspase-11,interleukin(IL)-1 β,IL-18,the proportion of pyroptosis cells and the relative expression level of GSDMD protein in children of each infection type were significantly increased compared with those before chemotherapy(P＜0.05).After chemotherapy,the levels of IL-4,IL-6,IL-10 and interfer-on-γ(IFN-γ)in the granulocytosis group were significantly higher than those in the non-granulocytosis group(P＜0.05),and the granulocyte level was negatively correlated with the levels of IL-4,IL-6,IL-10 and IFN-γ(P＜0.05).There were statistically significant differences in the levels of IL-4,IL-6,IL-10 and IFN-γ in dif-ferent infection states after chemotherapy(P＜0.05).Conclusion The number of granulocytes and the levels of serum cytokines can serve as potential indicators of infection in children with leukemia.The regulation of pyroptosis may provide new strategies for the treatment of childhood leukemia.

6-gingerol, a bioactive compound from ginger, has demonstrated promising anticancer properties across various cancer models by inducing apoptosis and inhibiting cell proliferation and invasion. In this study, we explore its mechanisms against glioblastoma multiforme (GBM), a notably aggressive and treatment-resistant brain tumor. We found that 6-gingerol crosses the blood-brain barrier more effectively than curcumin, enhancing its potential as a therapeutic agent for brain tumors. Our experiments show that 6-gingerol reduces cell proliferation and triggers apoptosis in GBM cell lines by disrupting cellular energy homeostasis. This process involves an increase in mitochondrial reactive oxygen species (mtROS) and a decrease in mitochondrial membrane potential, primarily due to the downregulation of manganese superoxide dismutase (MnSOD). Additionally, 6-gingerol reduces ERK phosphorylation by inhibiting EGFR and RAF, leading to G1 phase cell cycle arrest. These findings indicate that 6-gingerol promotes cell death in GBM cells by modulating MnSOD and ROS levels and arresting the cell cycle through the ERFR-RAF-1/MEK/ ERK signaling pathway, highlighting its potential as a therapeutic agent for GBM and setting the stage for future clinical research.

Radiation-induced thrombocytopenia(RIT)faces a perplexing challenge in the clinical treatment of cancer patients,and current therapeutic approaches are inadequate in the clinical settings.In this research,oxy-matrine,a new molecule capable of healing RIT was screened out,and the underlying regulatory mecha-nism associated with magakaryocyte(MK)differentiation and thrombopoiesis was demonstrated.The capacity of oxymatrine to induce MK differentiation was verified in K-562 and Meg-01 cells in vitro.The ability to induce thrombopoiesis was subsequently demonstrated in Tg(cd41:enhanced green fluorescent protein(eGFP))zebrafish and RIT model mice.In addition,we carried out network pharmacological pre-diction,drug affinity responsive target stability assay(DARTS)and cellular thermal shift assay(CETSA)analyses to explore the potential targets of oxymatrine.Moreover,the pathway underlying the effects of oxymatrine was determined by Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses,Western blot(WB),and immunofluorescence.Oxymatrine markedly promoted MK differentiation and maturation in vitro.Moreover,oxymatrine induced thrombopoiesis in Tg(cd41:eGFP)zebrafish and accelerated thrombopoiesis and platelet function recovery in RIT model mice.Mechanistically,oxymatrine directly binds to toll-like receptor 2(TLR2)and further regulates the downstream pathway stimulator of interferon genes(STING)/nuclear factor-kappaB(NF-κB),which can be blocked by C29 and C-176,which are specific inhibitors of TLR2 and STING,respectively.Taken together,we demonstrated that oxymatrine,a novel TLR2 agonist,plays a critical role in accelerating MK differentiation and thrombopoiesis via the STING/NF-κB axis,suggesting that oxymatrine is a promising candidate for RIT therapy.
