ObjectiveTo evaluate the effectiveness of exhalation-inhalation exercise on early pulmonary rehabi-litation for patients with acute exacerbation of chronic obstructive pulmonary disease （AECOPD）. MethodsA total of 120 participants with AECOPD were randomly divided into a treatment group and a control group， with 60 participants in each group. The control group treated with conventional western medicine， while the treatment group received exhalation-inhalation exercise training on the basis of conventional western medicine treatment， with 30 minutes per session and 5 sessions per week. The course of treatment for both groups was 12 weeks. The primary outcome was the 6-minute walking distance （6MWD）. The secondary outcomes included pulmonary function indexes including forced expiratory volume in one second/forced vital capacity （FEV1/FVC）， percentage of predicted forced expiratory volume in one second （FEV1%） and percentage of predicted forced vital capacity （FVC%）， St.George's Respiratory Questionnaire （SGRQ） score， modified Medical Research Council （mMRC） dyspnea scale score， COPD assessment test （CAT） score， hospital anxiety and depression scale-anxiety subscale ［HADS（A）］ score， and hospital anxiety and depression scale-depression subscale ［HADS（D）］ score. Meanwhile， safety of all participants was recorded and assessed. ResultsDuring the treatment， 12 participants dropped out from both the treatment group and the control group， with 48 participants in each group finally included in the analysis. The 6MWD of both groups after treatment was higher than that before treatment， and the 6MWD of the treatment group was higher than that of the control group （P＜0.05 or P＜0.01）. After treatment， the SGRQ score， mMRC score and CAT score of the treatment group were lower than those before treatment， while FEV1%， FVC% and FEV1/FVC were higher than those before treatment （P＜0.05）. Moreover， after treatment， the FEV1/FVC of the treatment group was higher than that of the control group， while the SGRQ score， mMRC score and CAT score were lower than those of the control group （P＜0.05 or P＜0.01）. There was no statistically significant difference in pulmonary function indexes， SGRQ score， mMRC score and CAT score after treatment in the control group （P＞0.05）. No statistically significant difference was observed in HADS（A） score and HADS（D） score after treatment within and between groups （P＞0.05）. The incidence of adverse reactions in the treatment group was 6.25% （3/48）， and 0 in the control group， with no statistically significant difference between groups （P＞0.05）. ConclusionExhalation-inhalation exercise for patients with AECOPD in early pulmonary rehabilitation can improve patients' exercise tole-rance， quality of life， clinical symptoms and pulmonary function， with good safety.

Objective To explore the independent risk factors for complicated coronary heart disease (CHD) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and to construct a risk prediction model. Methods A retrospective study was performed to analyze the clinical data of 308 OSAHS patients who visited Jiangsu Provincial People's Hospital from January 2021 to June 2025. The patients were divided into the CHD group (n=80) and non-CHD group (n=228) according to the presence or absence of complicated CHD. Independent risk factors were identified using univariate analysis and multivariate logistic regression, and a nomogram prediction model was constructed. The model was evaluated using the calibration curve, Hosmer-Lemeshow test, Decision Curve Analysis (DCA) curve, and Receiver Operating Characteristic (ROC) curve. Results The incidence of CHD in OSAHS patients was 25.97%. Age, history of hypertension, oxygen desaturation index (ODI), severe polysomnography (PSG) grade, decreased high-density lipoprotein cholesterol, elevated homocysteine, and elevated troponin I were independent risk factors for OSAHS complicated with CHD (P<0.05). The nomogram model demonstrated good calibration (Hosmer-Lemeshow test, P=0.995), and the DCA curve showed high clinical net benefit. The area under the ROC curve was 0.940 (95% CI: 0.908~0.972), with a sensitivity of 0.842 and a specificity of 0.900. Conclusion Age, history of hypertension, ODI, PSG grade, high-density lipoprotein cholesterol, homocysteine, and troponin I are independent risk factors for CHD in OSAHS patients. The prediction model constructed based on these factors can provide a reliable tool for clinical nurses to early identify high-risk individuals and formulate targeted intervention strategies.

Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

ObjectiveTo investigate the current status of HIV-related health service uptake among cross-border couples (Chinese husbands and Myanmar wives) in Dehong Dai and Jingpo Autonomous Prefecture (hereinafter referred to as Dehong Prefecture), and to provide evidence for optimizing HIV prevention and control strategies in border areas. MethodsA cross-sectional survey was conducted from September 2022 to September 2023 among 14 662 cross-border couples (Chinese husbands and Myanmar wives) in Dehong Prefecture. Data on sociodemographic characteristics, HIV/AIDS knowledge awareness, and utilization of HIV-related health services within the past year were collected. Multivariable logistic regression was used to analyze factors associated with HIV testing uptake among husbands and wives. ResultsA total of 29 324 individuals (14 662 couples) were included. The overall awareness rate of HIV/AIDS was 82.09%, with the rate among husbands significantly higher than that among wives (85.17% vs. 79.01%, P<0.001). Overall, 94.98% of participants had received at least one HIV-related health service, and the HIV testing rate in the past year was 65.52%. Multivariable logistic regression analysis showed that, compared with participants married for 0‒3 years, those married for 4‒10 years and ≥11 years were more likely to have received HIV testing. The corresponding ORs were 1.344 (95%CI: 1.187‒1.521) and 1.381 (95%CI: 1.211‒1.574) among husbands, and 1.308 (95%CI: 1.155‒1.481) and 1.344 (95%CI: 1.178‒1.533) among wives, respectively. Compared with those holding a marriage certificate, those possessing a border marriage registration certificate were positively associated with HIV testing uptake, with ORs of 1.710 (95%CI: 1.575‒1.857) among husbands and 1.700 (95%CI: 1.565‒1.847) among wives. Compared with illiterate participants, those with primary school education showed lower testing rates, with ORs of 0.738 (95%CI: 0.650‒0.837) among husbands and 0.827 (95%CI: 0.766‒0.891) among wives. Additionally, a history of sexually transmitted diseases (OR=3.656, 95%CI: 1.243‒15.589) and participation in the New Rural Cooperative Medical Scheme (OR=1.51, 95%CI: 1.179‒1.935) were independently associated with higher testing rates among husbands. ConclusionThe overall utilization of HIV-related health services among cross-border couples in Dehong Prefecture is satisfactory, but significant gender disparities exist, with foreign wives showing lower rates of knowledge awareness and lower proportions obtaining such knowledge through certain channels compared with their Chinese husbands. Couples with shorter marriage duration, those with primary school education, and those not included in the border marriage registration system are vulnerable groups with lower HIV testing uptake. Future interventions should prioritize cross-border marriage families at the early stage of entry and in the newly married period. Based on the border marriage registration management system and primary healthcare networks, health education and HIV testing services targeting foreign spouses should be strengthened to improve service accessibility and equity.

Objective To investigate whether transcutaneous electrical acupoint stimulation(TEAS)can improve the muscle strength,endurance and work efficiency of calf muscles in healthy young men,aiming to explore a new method for preventing and combating microgravity-induced muscle atrophy in space environments.Methods 40 healthy young men aged 18-35 years were randomly divided into a Control group(Pseudo Transcutaneous Electrical Acupoint Stimulation)and a Experimental group(Transcutaneous Electrical Acupoint Stimulation)in a 1∶1 ratio,with 20 participants in each group.In the Control group,the indicator light of the stimulator was covered,and the device was turned on,but the electrodes did not contact the skin,The device automatically turned offafter 3 seconds.In the Experimental group,the TEAS device was connected to the current and TEAS intervention was performed.The electrical stimulation waveform was a sperse-dense wave with a frequency of 4/20 Hz,and the intensity was determined by patient tolerance.The acupoints selected for electrical stimulation in both groups were bilateral Zusanli(ST36)、Liangqiu(ST34),Taixi(KI3),and Fuliu(KI7).Zusanli and Liangqiu were paired,and Taixi and Fuliu were paired.The intervention frequency was 30 min/time,1 time/day,6 days/week,for 2 weeks.The relative peak torque at 60°/s,relative peak torque at 180°/s,and average power at 180°/s of the bilateral calf muscles were measured using an isokinetic dynamometer at 0th,7th,and 14d day of the experiment.Results After 1 week of TEAS,compared with Control group,there were no significant changes in the relative peak torque at 60°/s,relative peak torque at 180°/s and average power at 180°/s of the bilateral anterior calf muscles in the Experimental group(all P>0.05);however,compared with Control group,the relative peak torque at 60°/s and the relative peak torque at 180°/s of the bilateral posterior calf muscles in the Experimental group were significantly increased(all P<0.05).After 2 weeks TEAS;compared with the Control group,there were no significant changes in the relative peak torque at 60°/s,relative peak torque at 180°/s and average power at 180°/s of the bilateral anterior calf muscles in the Experimental group(all P>0.05);however,the relative peak torque at 60°/s,relative peak torque at 180°/s,and average power at 180°/s of the bilateral posterior calf muscles were significantly increased in the Experimental group(all P<0.05).Conclusion TEAS of Zusanli,Liangqiu,Fuliu and Taixi acupoints on the lower limbs for 2 weeks can effectively improve the maximum muscle strength,endurance and work efficiency of the posterior calf muscles in healthy young men.

Objective To identify the independent predictors of programmed death-1 (PD-1) inhibitor-related endocrine adverse events and construct a clinically usable risk prediction model. Methods A total of 302 patients with solid tumors treated with PD-1 inhibitors were retrospectively enrolled. According to the presence or absence of endocrine immune-related adverse events (irAEs), the patients were divided into case group and control group. The clinical and laboratory indexes were compared between the two groups. Multivariable logistic regression was used to confirm independent predictors of endocrine irAEs. The nomogram was constructed, while the receiver operating characteristic (ROC) curve was used to test the prediction performance of the model. Results The overall incidence of endocrine irAEs was 21.9% (66/302), and the incidence of hypothyroidism was 19.5% (59/302). The age, PD-1 inhibitors, free thyroxine, thyroid peroxidase antibody (TPOAb), thyroglobulin, amylase, lymphocyte subset CD3 expression were statistically different between the two groups (P＜0.05). Multivariable logistic regression showed that higher expression of lymphocyte subset CD3 was a protective factor to prevent endocrine irAEs occurrence (P＝0.004), while age＜60 years, higher TPOAb and use of pembrolizumab were independent risk factors of endocrine irAEs (P＜0.05). The nomogram model thus constructed, and when the threshold probability of the model exceeded 0.1, its net benefit was higher. ROC curve showed that the AUC of the model to predict endocrine irAEs was 0.760. The prediction result of the model was highly consistent with the actual result. Conclusions The age, type of PD-1 inhibitor, baseline TPOAb level, and baseline CD3 expression can independently predict endocrine irAEs occurrence or not. The nomogram model based on this model has good predictive efficiency, which can provide reference for early identification of high-risk patients and immunotherapy management.

Colorectal cancer(CRC) is one of the most common malignant tumors worldwide, primarily originating from recurrent inflammatory bowel disease(IBD). Therefore, blocking the inflammation-cancer transformation in the colon has become a focus in the early prevention and treatment of CRC. The inflammation-cancer transformation in the colon involves multiple types of cells and complex pathological processes, including inflammatory responses and tumorigenesis. In this complex pathological process, immune cells(including non-specific and specific immune cells) and non-immune cells(such as tumor cells and fibroblasts) interact with each other, collectively promoting the progression of the disease. In traditional Chinese medicine(TCM), inflammation-cancer transformation in the colon belongs to the categories of dysentery and diarrhea, with the main pathogenesis being cold and heat in complexity. This paper first elaborates on the complex molecular mechanisms involved in the inflammation-cancer transformation process in the colon from the perspectives of inflammation, cancer, and their mutual influences. Subsequently, by comparing the pathogenic characteristics and clinical manifestations between inflammation-cancer transformation and the TCM pathogenesis of cold and heat in complexity, this paper explores the intrinsic connections between the two. Furthermore, based on the correlation between inflammation-cancer transformation in the colon and the TCM pathogenesis, this paper delves into the importance of the interaction between inflammation and cancer. Finally, it summarizes and discusses the clinical and basic research progress in the TCM intervention in the inflammation-cancer transformation process, providing a theoretical basis and treatment strategy for the treatment of CRC with integrated traditional Chinese and Western medicine.

This study aims to evaluate the therapeutic effect of Alpiniae Oxyphyllae Fructus-Saposhnikoviae Radix(AOF-SR) in a diabetic kidney disease(DKD) mouse model, explore its potential mechanism in regulating the NOD-like receptor protein 3(NLRP3) inflammasome via phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR) signaling pathway, and provide new theoretical support for traditional Chinese medicine(TCM) intervention in DKD. Using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), the active ingredients and potential targets of AOF-SR were screened and its molecular mechanisms were investigated through molecular docking, molecular dynamics simulations, and experimental validation. The db/db mice were randomly divided into four groups: model group, low-dose AOF-SR group, high-dose AOF-SR group, and canagliflozin group. The db/m mice served as normal group. After one week of acclimatization, the mice underwent drug intervention. Starting from one week after treatment, body weight, blood glucose levels, and 24-hour urinary protein(24hUP) were measured every two weeks. After 13 weeks of administration, tissue collection and indicator detection were performed. Blood glucose, 24hUP, urinary microalbumin(mAlb), serum creatinine(Scr), and blood urea nitrogen(BUN) levels were determined. Pathological changes in kidney tissue were observed using hematoxylin-eosin(HE) staining. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of serum IL-1β, IL-18, and caspase-1, while RT-qPCR was employed to measure the mRNA expression levels of IL-1β, IL-18, caspase-1, and NLRP3. Western blot was used to assess the protein expression levels of NLRP3, PI3K, p-Akt, Akt, p-mTOR, and mTOR. Network pharmacology analysis indicated that wogonin, pinocembrin, hancinol, and kaempferol were the core compounds for drug treatment of the disease. Molecular docking and molecular dynamics simulations showed that core compounds, particularly wogonin, could specifically bind to PIK3R1, thereby regulating the PI3K/Akt/mTOR pathway. The experimental results indicated that both low and high doses of AOF-SR and canagliflozin significantly reduced blood glucose, 24hUP, mAlb, Scr, and BUN levels in db/db mice, while improving kidney pathological damage and inflammatory cell infiltration. Moreover, the treatments reduced the mRNA expression levels of caspase-1, IL-1β, and IL-18 in the kidneys of db/db mice, as well as the secretion of these factors in the serum. The drugs also inhibited the mRNA and protein expression levels of NLRP3 in the kidneys of db/db mice and decreased the protein levels of PI3K, p-Akt/Akt, and p-mTOR/mTOR. In conclusion, AOF-SR may improve kidney inflammation in DKD mice by regulating the PI3K/Akt/mTOR signaling pathway and inhibiting NLRP3 inflammasome activation.
