ObjectiveTo investigate the correlation between neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， systemic immune-inflammation index （SII） and the severity of intrauterine adhesions （IUA）. MethodsThe retrospective study included 380 patients who underwent transcervical resection of adhesions （TCRA） from December 2019 to March 2025. Based on the American Fertility Society （AFS） classification， patients were divided into mild （n=61）， moderate （n=225）， and severe （n=94） groups. NLR， PLR， and SII were calculated from preoperative blood tests. Statistical analyses included Kruskal-Wallis test and ordinal Logistic regression. ResultsNLR， PLR， and SII were significantly higher in the severe IUA group compared to the mild group （P<0.05）， with SII showing the strongest predictive ability （OR=1.004， P=0.001）. The number of intrauterine procedures was an independent risk factor （OR=1.27/level， P=0.016）. The predictive model ［Logit（P）=-0.676+0.241×operation times+0.004×SII］ effectively identified severe IUA cases. ConclusionInflammatory markers （particularly SII） are correlated with IUA severity and may serve as non-invasive tools for clinical assessment.

Objective To identify the cuproptosis genes associated with prognosis and immune microenvironment in lung cancer with the use of bioinformatics.Methods The lung cancer dataset used in this study was obtained from the TCGA database.The cuproptosis-related genes(CRGs)were obtained from the previously reported literature.The R software Deseq2 package was used to identify the differentially expressed genes(DEGs)in lung cancer.The intersection of DEGs and CRGs was taken to obtain the differentially expressed CRGs(DE-CRGs).COX analysis and R software rms package were used to identify DE-CRGs associated with the prognosis of lung cancer.Estimate and Cibersort algorithms were applied to identify the correlation of DE-CRGs with the immune microenvironment.Results Compared to the normal tissues,a total of 5,269 DEGs were present in lung cancer tissues in the TCGA database,and there were 11 shared genes between DEGs and CRGs.The 11 DE-CRGs mainly regulated the energy metabolism,carbon metabolism and amino acid metabolism.In the DE-CRGs,LIPT1 was an independent risk factor for lung cancer,and the column chart constructed with the clinical features(age,TNM staging,and residual tumor)predicted the survival of lung cancer patients in a manner similar to their actual outcomes.LIPT1 showed a positive correlation with the infiltration of M1 and M2 type macrophages,activated natural killer cells cells and CD8+T cells,and showed a significant negative correlation with M0 type macrophages,activated mast cells,neutrophils and Treg cells(P<0.05).Conclusion LIPT1 may serve as a prognostic and immune microenvironment-associated cuproptosis gene,which is a novel biomarker for lung cancer therapy.

Objective To observe the therapeutic effect and mechanism of Xinmaikang Prescription for mice with atherosclerosis(AS).Methods A high-fat diet feeding method was used to construct an AS ApoE-/-mouse model.Successful modeled mice were randomly divided into four groups,i.e.,the model group,the Atorvastatin group,and the low-and high-dose groups of Xinmaikang Prescription,with eight mice in each group.A normal group(eight mice)was also set up.After 12 weeks of corresponding intervention in each group,the pathological changes of aorta were observed by oil red O staining,enzyme-linked immunosorbent assay(ELISA)was used to determine the contents of interleukin 1β(IL-1β)and interleukin 18(IL-18)in serum,and real-time quantitative polymerase chain reaction(qPCR)was used to detect the mRNA expression levels of pyroptosis-associated proteins nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)and cysteine protein hydrolase 1(Caspase-1)as well as inflammatory factors IL-1β and IL-18 in aorta tissues,and Western Blot method was used to detect the protein expression levels of NLRP3,Caspase-1,IL-1β and IL-18 in aortic tissues.Results Compared with the normal group,the intima thickness in the model group was significantly increased,and a large number of lipid plaques and inflammatory cell infiltration appeared in aorta,the contents of IL-1β and IL-18 in serum were elevated(P<0.01),and the mRNA and protein expression levels of NLRP3,Caspase-1,IL-1β and IL-18 in the aortic tissues were significantly increased(P<0.01);in the Xinmaikang Prescription high-dose group and Atorvastatin group,the lipid droplets and area of vulnerable plaques in aortic tissues were significantly reduced,and the serum levels of IL-1β and IL-18 were decreased(P<0.01),and the mRNA and protein expression of NLRP3,Caspase-1,IL-1β and IL-18 in aortic tissues were significantly reduced(P<0.01).Conclusion Xinmaikang Prescription may effectively reduce the inflammatory response and pyoptosis of vascular endothelial cells in AS model mice through regulating the NLRP3/Caspase-1/IL-1β signaling pathway,thus exerting the effect of preventing and treating AS.

OBJECTIVE To explore the effects of Lishukang capsules on hypoxic pulmonary artery hypertension （HPAH） rats by regulating the HIF-1α/NF-κB signaling pathway. METHODS Sixty rats were randomly divided into control group， model group， positive control group （sildenafil， 30 mg/kg）， Lishukang low-， medium- and high-dose groups （Lishukang capsules 6， 12， 18 g/kg）， with 10 rats in each group. Except for control group， the HPAH model was induced by intermittent hypoxia method （simulating an altitude of 5 000 m） in other groups； at the same time， they were given relevant medicine or normal saline intragastrically， for consecutive 28 days. Within 24 hours of the last administration， the mean pulmonary artery pressure （MPAP） and right ventricule hypertrophy index （RVHI） of rats were detected； pathological morphology of lung tissue was observed， and the expression of α-smooth muscle actin （α-SMA）， mRNA expressions of HIF-1α and NF-κB as well as protein expressions of HIF-1α and NF-κB p65 in lung tissue were determined. RESULTS Compared with model group， MPAP and RVHI in Lishukang medium- and high-dose groups and positive control group were all decreased significantly （P＜0.05）； the expression of α-SMA， mRNA expressions of HIF-1α and NF-κB， and protein expressions of HIF-1α and NF-κB p65 in lung tissue were all decreased significantly （P＜0.05）； additionally， pulmonary vascular remodeling was improved to varying degrees. CONCLUSIONS Lishukang capsules may protect HPAH rats， the mechanism of which may be associated with inhibiting the HIF-1α/NF- κB signaling pathway.

Objective:To investigate the impact of virtual navigation bronchoscopy on perioperative information in patients undergoing thoracoscopic pulmonary resection.Methods:Employed three distinct propensity score matching models to effectively address the baseline data disparities among patients undergoing thoracoscopic pulmonary resection. Categorized the patients into two groups: pulmonary wedge resection and pulmonary segmentectomy. Compared the disparities in clinical characteristics, intraoperative lesion resection, and postoperative recovery between patients who underwent virtual navigation bronchoscopy assisted localization prior to surgery and those who did not employ any specific localization methods.Results:This reserch included a total of 127 patients who underwent localization assisted by virtual navigation bronchoscopy, and 122 patients who did not undergo specialized localization. After propensity score matching, the navigation group demonstrated a statistically significant reduction in intraoperative blood loss[model 3, 40(20, 50) ml vs. 50(20, 100) ml, P=0.027], drainage volume on the first day post-surgery[model 3, 100(50, 175) ml vs. 150(100, 220) ml, P=0.023], and incidence of residual pleural effusion(model 3, 31 cases vs. 38 cases, P=0.046) compared to the non-positioning group among patients undergoing pulmonary wedge resection. In the pulmonary segmentectomy group, we observed a reduction in intraoperative blood loss[model 3, 50(30, 100) ml vs. 100(50, 100) ml, P=0.003] and incidence of residual pneumothorax(model 3, 18 cases vs. 28 cases, P=0.012) in patients who underwent navigation-assisted procedures compared to those without specialized positioning. Conclusion:The utilization of virtual navigation bronchoscopy for preoperative localization assistance in thoracoscopic sublobectomy(including wedge resection and segmental resection) may represent a viable approach to mitigate intraoperative injury and facilitate postoperative recovery.

Objective To establish an electrical field(EF)stimulation model for Schwann cells(SCs),and to provide a basis for exploring the mechanisms of EF stimulation in promoting proliferation,migration and epithelial-to-mesenchymal transition of SCs.Methods A YC-3 bipolar programmable electrical stimulator and an electrotaxis chamber were used to construct an EF stimulation system to stimulate SCs.In the study,SCs were divided into control group(Ctrl)receiving no EF stimulation and EF group stimulated by continuous constant-voltage EF(100 mV/mm,3 h).The effects of EF stimulation on the proliferation and migration of SCs were analyzed using CCK-8 assay,and wound healing assay+Transwell assay,separately;and its effect on SCs adhesion was observed by analyzing the expressions of E-cadherin and N-cadherin using Western Blot.Results The CCK-8 assay results suggested that the absorbance at 450 nm was significantly higher in EF group than in Ctrl group(P<0.05).The results of wound healing assay+Transwell assay revealed that EF group had higher cell migration efficiency than Ctrl group(P<0.05).Western Blot results showed decreased E-cadherin expression and increased N-cadherin expression in EF group as compared with Ctrl group(P<0.05).Conclusion The improved EF stimulation system for SCs is operable.EF stimulation can promote the proliferation and migration of SCs.The decreased E-cadherin expression and increased N-cadherin expression may be related to the occurrence of epithelial-to-mesenchymal transition in SCs after EF stimulation.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Reading is an important way for acquiring knowledge,enhancing humanistic literacy,and alleviating negative moods.This paper,based on a survey of the reading habits of medical staff at a public hospital with 1 508 valid samples,found that the reading preferences were closely associated with factors such as educational background,age,job position,gender,and length of service.Drawing from these insights,this paper proposed recommendations to improve the quantity and quality of read-ing among medical professionals.Additionally,suggestions were made for the construction of a humanistic environment and cul-tural development within public hospitals,aiming to foster a favorable cultural atmosphere and enhance the humanistic care pro-vided to patients.
