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 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 evaluate the clinical efficacy of ultrasound-guided needle knife release with different pathways for carpal tunnel syndrome (CTS). METHODS: Sixty CTS patients were randomly divided into a transverse group and a longitudinal group, with 30 patients in each group. The transverse group received the needle knife release under ultrasound above and below the median nerve along the short axis, while the longitudinal group received the needle knife release under ultrasound above the median nerve along the long axis. The patients' visual analogue scale (VAS) scores, Levine scores, and median nerve cross-section area (CSA) were assessed before treatment, on the 7th, 14th, and 30th days after treatment. The median nerve conduction indexes (motor conduction: latency [Lat], amplitude[Amp], motor conduction velocity [MCV]; sensory conduction: Lat, Amp, sensory conduction velocity [SCV]) were evaluated before treatment and on the 30th day after treatment. RESULTS: Compared before treatment, the VAS scores, Levine scores, and median nerve CSA were reduced in both groups on the 7th, 14th, and 30th days after treatment (P<0.05); the transverse group showed lower VAS and Levine scores and smaller CSA than those in the longitudinal group (P<0.05). On the 30th day after treatment, motor and sensory Lat was reduced (P<0.05), motor and sensory Amp was increased (P<0.05), and MCV and SCV were faster (P<0.05) in both groups. The transverse group had shorter Lat, higher Amp, and faster MCV and SCV than those in the longitudinal group (P<0.05). CONCLUSION The ultrasound-guided needle knife release with transverse and longitudinal pathways could both effectively alleviate pain and improve median nerve conduction in CTS patients, with the transverse pathway showing superior efficacy to longitudinal pathway.

OBJECTIVES: Non-small cell lung cancer (NSCLC) is associated with poor prognosis, with 30% of patients diagnosed at an advanced stage. Mutations in the EGFR and KRAS genes are important prognostic factors for NSCLC, and targeted therapies can significantly improve survival in these patients. Although tissue biopsy remains the gold standard for detecting gene mutations, it has limitations, including invasiveness, sampling errors due to tumor heterogeneity, and poor reproducibility. This study aims to develop machine learning models based on radiomic features to predict EGFR and KRAS gene mutation status in NSCLC patients, thereby providing a reference for precision oncology. METHODS: Imaging and mutation data from eligible NSCLC patients were obtained from the publicly available Lung-PET-CT-Dx dataset in The Cancer Imaging Archive (TCIA). A three-dimensional-convolutional neural network (3D-CNN) was used to extract imaging features from the regions of interest (ROI). The LightGBM algorithm was employed to build classification models for predicting EGFR and KRAS gene mutation status. Model performance was evaluated using 5-fold cross-validation, with receiver operator characteristic (ROC) curves, area under the curve (AUC), accuracy, sensitivity, and specificity used for validation. RESULTS: The models effectively predicted EGFR and KRAS mutations in NSCLC patients, achieving an AUC of 0.95 for EGFR mutations and 0.90 for KRAS. The models also demonstrated high accuracy (EGFR 89.66%; KRAS 87.10%), sensitivity (EGFR 93.33%; KRAS 87.50%), and specificity (EGFR 85.71%; KRAS 86.67%). CONCLUSIONS A radiogenomics-machine learning predictive model can serve as a non-invasive tool for anticipating EGFR and KRAS gene mutation status in NSCLC patients.

Chronic heart failure (CHF) is a pathological state in which the cardiac ejection fraction is insufficient to meet an individual's metabolic needs owing to changes in the cardiac structure or function. Various etiologies such as myocardial infarction and inflammation are implicated, and the main symptoms are dyspnea, lower limb edema, fatigue, and discomfort during rest or exercise. CHF is the primary outcome of cardiovascular disease, and the increasing morbidity and mortality rates highlight the significant risks of this condition. According to traditional Chinese medicine, the pathogenesis of CHF is deficiency of heart qi and heart yang, which predominantly affects the heart, but may also impede the function of other zang-organs such as the spleen and kidney, and aggravate the symptoms of heart failure. With technological advancements and enhanced awareness of health conditions and disease prevention, China has promoted traditional medicine practices such as medicine and food homology (MFH), which has received increasing attention in recent years. This concept stipulates that certain medicines and foods have the same origin; ergo, these foods have medicinal properties, with many being used in the prevention and treatment of CHF. However, the efficacy and safety of MHF substances have yet to be determined, and there is no consensus regarding the development of disease prevention and treatment strategies. This article therefore reviews the current evidence for MFH in the prevention and treatment of CHF by summarizing the therapeutic potential of this practice and discussing treatment strategies and aims to improve the understanding of Chinese medicine and food homologous substances in the treatment of this condition, as well as highlight the current literature and avenues for future research.

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 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.

Tumor microenvironment(TME)is a complex cellular environment where tumor cells reside,along with various types of cells and extracellular components surrounding the tumor cells.Immune cells are key components of TME,including tumor-associated macrophages(TAMs),myeloid-derived suppressor cells(MDSCs),lymphocytes,regulatory T cells(Tregs),natural killer cells(NK cells),dendritic cells(DCs),and many others.It is worth noting that drug resistance is currently a major factor limiting the efficacy of cancer treatment methods such as chemotherapy,radiotherapy,targeted therapy,and immunotherapy,and a leading cause of treatment failure.Research has found that the development of drug resistance in tumor cells is the result of interactions between tumor cells and TME.Consequently,overcoming drug resistance in tumors caused by TME is considered a significant challenge in cancer treatment.In recent years,with in-depth research into immune cells within TME,significant progress has been made in understanding the specific mechanisms by which immune cells regulate drug resistance in tumor cells.Furthermore,therapeutic strategies that target these immune cells,signaling pathways,or cytokines have been shown to effectively combat tumor drug resistance and enhance the therapeutic outcomes of cancer treatment.This article reviews the research advancements regarding the roles of TAMs,MDSCs,Tregs,and NK cells in tumor drug resistance within TME and discusses the development of targeting strategies to overcome this resistance.Additionally,we explore the relationship of tumor-associated neutrophils(TANs)and B regulatory cells(Bregs)with tumor drug resistance.It is hoped that this review will offer insights and serve as reference for reducing tumor drug resistance and improving the efficacy of anti-tumor therapies.

Objective To observe the value of chocolate balloon(controlled dilatation technique)for vascular preparation of endovascular treatments for lower extremity arteriosclerosis obliterans(ASO).Methods Data of 110 patients with lower extremity ASO who underwent vascular preparation with chocolate balloon were retrospectively analyzed.The type of ASO,with calcification or not and so on were recorded,and the success rate of vascular preparation with chocolate balloon and the therapeutic effect of endovascular treatments for ASO were evaluated.Results Among 110 patients,unilateral lower extremity ASO were found in 100 cases,while bilateral lower extremities ASO were noticed in 10 cases,including 100(100/120,83.33%)chronic occlusive lesions,8(8/120,6.67%)stenotic lesions and 12(12/120,10.00%)thrombotic lesions.Calcification with grade 3-4 were observed in 50 lesions(50/120,41.67%).The technical success rate of vascular preparation with chocolate balloon was 92.50%(111/120),while 7(7/120,5.83%)lesions developed flow-limiting dissection after chocolate balloon dilatation and 2(2/120,1.67%)lesions had significant residual stenosis that did not meet the technical success criteria,which underwent stent implantation without drug-coated balloon(DCB).Besides,flow-limiting dissection were noticed in 15 lesions after DCB,hence salvage stents were implanted.The success rate of endovascular treatments of ASO was 100%.Conclusion Chocolate balloon(controlled dilation technique)was valuable for vascular preparation of endovascular treatments for lower extremity ASO.

Objective To compare the short-term efficacy and occurrence of complication of endoscopic laminar fenestration (Endo-LOVE) and percutaneous endoscopic transforaminal decompression (PETD) in patients with degenerative lumbar lateral recess stenosis (LSLRS). Methods A total of 160 patients with LSLRS were enrolled as study objects, and were randomly assigned to control group (treated with PETD) and observation group (treated with Endo-LOVE), with 80 patients in each group. Surgical indicators, occurrence of complications, and therapeutic effects were observed and compared between the two groups. Bone lateral recess angle, soft lateral recess angle, Oswestry Disability Index (ODI) score, pain score, and Japanese Orthopaedic Association (JOA) score were compared before and after surgery. Results The observation group had less intraoperative blood loss, and shorter operative and hospital stays than the control group (P < 0.05). There were no statistically significant differences in the incidence of complications such as lower limb numbness, fever, and postoperative low back pain between the two groups (P>0.05). There were no statistically significant differences in preoperative bone lateral recess angle or soft lateral recess angle between the two groups (P>0.05). At 72 hours postoperatively, both angles increased in both groups compared with preoperative values, and the observation group had larger angles than the control group (P < 0.05). There were no statistically significant differences in preoperative pain score, ODI score, or JOA score between the two groups (P>0.05). At 3 months postoperatively, JOA scores increased and pain scores as well as ODI scores decreased in both groups compared with preoperative values, with the observation group having higher JOA scores and lower pain scores as well as ODI scores than the control group (P < 0.05). The excellent and good rate was 96.25%(77/80) in the observation group, which was higher than 87.50%(70/80) in the control group (P < 0.05). Conclusion Compared with the PETD approach, the Endo-LOVE approach for the treatment of LSLRS offers shorter operative time, less intraoperative blood loss, and better short-term efficacy.
