AIM:The aim of our study is to investigate the metabolic profile differences during cervical lesion progression and evaluate their potential clinical value in assisting the diagnosis of cervical cancer(CC).METHODS:Ul-tra-high-performance liquid chromatography coupled with high-resolution mass spectrometry(UHPLC-HRMS)was em-ployed to conduct non-targeted metabolomic analysis of cervical swab samples from 43 CC patients,34 high-grade squa-mous intraepithelial lesion(HSIL)patients,and 43 healthy controls.Based on the distinct features among the three groups,principal component analysis(PCA)was used to identify the metabolic differences among CC,HSIL and healthy groups.MetaboAnalyst 5.0 was then employed to perform KEGG pathway enrichment analysis on the differential metabo-lites.Finally,random forest machine learning algorithm was used to construct classification prediction models for distin-guishing CC from healthy,HSIL from healthy,and CC from HSIL.The performance of these models was evaluated using receiver operating characteristic(ROC)curve analysis.RESULTS:A total of 1 543 metabolites were identified across the healthy,HSIL and CC groups after filtration,with 407 metabolites differing between the groups.The study found that metabolite PGE2 was present in all three groups,with its expression levels progressively increasing with the progression of cervical lesions.Differential metabolite enrichment analysis demonstrated that CC is associated with specific cancer-relat-ed metabolic pathways,including the tricarboxylic acid cycle,tyrosine metabolism,tryptophan metabolism,and the pen-tose phosphate pathways.Additionally,the study developed three prediction models based on metabolic products for diag-nosing HSIL and CC:the full model,the simplified model,and the PGE2 model.The results indicated that metabolites ex-hibited strong diagnostic efficiency.Both the full model and the simplified model effectively distinguished CC from HSIL,CC from healthy,and HSIL from healthy.The AUC values for the full model were 0.90,0.92 and 0.84,respectively,while those for the simplified model were 0.81,0.95 and 0.85,respectively.Furthermore,the PEG2 model achieved AUC values of 0.74 and 0.80 for distinguishing CC from healthy and HSIL from healthy,respectively.CONCLUSION:The metabolic profiles of cervical cancer exhibit significant differences during the progression of cervical cancer,and these metabolites hold potential clinical value as biomarkers for cervical lesions.

ObjectiveTo study the relationship between qi stagnation constitution and suboptimal health status (SHS) or lifestyle.MethodsFrom 2012 to 2013, we conducted a cross-sectional survey of 24 159 Chinese individuals aged 12–80 years. The qi stagnation constitution was assessed using the Constitution in Chinese Medicine Questionnaire. Health status was evaluated through medical records and the Subhealth Measurement Scale V1.0 (SHMS V1.0). Health-promoting lifestyles were measured using the Health-Promoting Lifestyle Profile II (HPLP-II).ResultsOf the 24 159 participants, 16.1% and 15.2% were classified as “always” and “sometimes” having the qi stagnation constitution, respectively. Those classified as “rarely” having the qi stagnation constitution scored higher on both the HPLP-II and SHMS V1.0. The participants classified as “always” having the qi stagnation constitution showed a significant association with SHS or disease compared to other imbalanced constitutions. Those in the “always” category were approximately 21 times more likely to be classified as having SHS (odds ratio [OR]: 21.17, 95% confidence interval [CI]: 15.74–28.45), whereas those in the “sometimes” category were approximately six times more likely (OR: 5.89, 95% CI: 5.04–6.90). Accordingly, the qi stagnation constitution score was significantly associated with the diagnosis of SHS, with an area under the curve of 0.77 (P .001). A score of 18.75 yielded the highest Youden Index (0.407), with a sensitivity of 60.5% and a specificity of 80.3%. Significant associations were observed between health-promoting lifestyles and qi stagnation constitution severity in an ordinal regression analysis (P .001). Protective factors included stress management (OR: 1.59), self-actualization (OR: 1.57), and exercise (OR: 1.36). In contrast, poorer interpersonal relationships (OR: 0.79), greater health responsibilities (OR: 0.86), and poorer nutrition (OR: 0.91) were associated with increased severity.ConclusionModulating the qi stagnation constitution through lifestyle interventions may help prevent the progression of SHS to disease, which aligns with core preventive principles in traditional Chinese medicine.

Objective To explore the authentic experiences of needle-related distress during arteriovenous fistula cannulation in hemodialysis patients and provide a basis for developing targeted assessment tools and intervention plans in clinical practice.Methods This study adopted a descriptive phenomenological research method.Using purposive sampling,13 hemodialysis patients with arteriovenous fistula from the blood purification center of a tertiary hospital in Changzhou were recruited for semi-structured interviews between November 2024 and January 2025.Data were analyzed using Colaizzi's 7-step method.Results Totally 4 themes and 10 sub-themes were extracted,namely dynamic evolution of distressing experiences(cognitive gaps and unfamiliar environments triggering distress,familiarity with procedures and self-management alleviating distress,sudden medical events reawakening distress),embodied cognition of distressing experiences(somatic distress,cognitive distress,mind-body dualistic interaction),subjective interaction in distress perception(subjective perceptions of differences in puncture skills,positive regulation through good communication attitudes),coping strategies for distressing experiences(empowerment-based coping,adaptive compromise).Conclusion The needle-related distress associated with arteriovenous fistula puncture in hemodialysis patients is not a single physical feeling,but a complex experience involving physical and mental interaction,nurse-patient interaction and coping strategies.Clinically,a dynamic assessment and precise intervention system should be constructed to improve patients' puncture experience and quality of life.

Objective To explore surgical treatment efficacy for PAES.Methods A retrospective analysis was done on 12 PAES patients'surgery in our hospital from March 2018 to December 2023.Surgical plans included double popliteal artery exploration and repositioning with tendon transplantation,popliteal artery and vein release plus arterial thrombus removal,popliteal fossa exploration with popliteal artery release,and autologous vein patch angioplasty plus abnormal muscle bundle resection.Results Follow-up was 3 months to 5 years.11 patients had good affected limb skin temperature and blood supply,no symptom recurrence.One patient had left lower limb skin temperature decrease and pallor 2 years post-op(diagnosed as left popliteal fossa traumatic neuroma compressing popliteal artery),with blood supply restored after tumor removal.Conclusion Open surgery(tendon transplantation,vein patch)for PAES is effective.

Diabetic nephropathy （DN） is one of the serious and common microvascular complications of diabetes mellitus （DM） and the main cause of end-stage renal disease （ESRD）. Endoplasmic reticulum stress （ERS） is a common stress defense mechanism in eukaryotic cells. In the ERS state， cells activate the unfolded protein response （UPR） to enhance the folding of unfolded proteins and the degradation of misfolded proteins， so as to restore the normal physiological function of the endoplasmic reticulum and avoid cell damage. However， excessive or chronic persistent ERS can induce apoptosis， inflammation， oxidative stress and other pathways to eventually cause cell damage. In recent years， a large number of studies have confirmed that ERS is closely associated with the occurrence and development of DN. In the case of DN， ERS is involved in the damage or protection of podocytes， glomerular mesangial cells， renal tubular epithelial cells， and glomerular endothelial cells. The regulation of ERS has become one of the hotspots in the prevention and treatment of DN and has received extensive attention in the field of traditional Chinese medicine. This paper systematically expounds the role of ERS in the occurrence and development of DN and summarizes the ERS-targeted regulation of DN by traditional Chinese medicine， with a view to providing certain research ideas for the prevention and control of DN with traditional Chinese medicine.
