This article systematically explores the traditional Chinese medicine （TCM） pathogenesis evolution and metastatic mechanisms of advanced gastric cancer from the perspective of "phlegm-toxin flowing infusion". Based on this theory， it is proposed that advanced gastric cancer presents a pathogenesis evolution characterized by healthy qi depletion， phlegm-toxin flowing infusion， and collateral damage with blood stasis. Healthy qi depletion is the root of the disease， in which spleen and kidney insufficiency leads to weakened healthy qi and inability to resist pathogenic factors. Phlegm-toxin flowing infusion is the core pathogenesis， where phlegm-dampness and cancer toxin intertwine and migrate to other organs along with qi movement. Collateral damage with blood stasis constitutes the final pathological stage of metastasis， where phlegm-toxin obstruction damages the collaterals， and congealed qi and blood form accumulations. On this basis， the meridian pathways and metastasis mechanisms of advanced gastric cancer spreading to multiple sites such as the liver， peritoneum， lungs， bones， brain， ovary， and lymph nodes are further analyzed， providing references for clinical management and research of this disease.

ObjectiveTo investigate the current status of assistive device use and unmet needs among persons with disabilities in Sichuan-Chongqing region, and to identify the key factors associated with satisfaction with these devices. MethodsFrom October, 2024 to February, 2025, quota sampling was adopted to recruit 1 040 persons with disabilities in Sichuan and 260 persons with disabilities in Chongqing. Telephone and online questionnaires were used to collect data on demographic characteristics, status of assistive device utilization and unmet assistive device needs, as well as satisfaction with assistive device use. Correlation analysis, multiple linear regression analysis and structural equation modeling were performed to identify key factors associated with satisfaction. ResultsA total of 1 186 valid responses were collected, of which 942 were from Sichuan Province and 244 from Chongqing Municipality. The utilization rate of assistive devices among persons with disabilities in Sichuan-Chongqing region was 61.9%, and the rate of unmet assistive device needs was 30.6%. The assistive device utilization rate of participants with agricultural household registration (57.98%) was lower than that of participants with non-agricultural household registration (66.86%). The utilization rate showed a J-shaped upward trend with the increase of educational attainment. Educational attainment (P = 0.002), perceived usefulness of assistive devices (P < 0.001), home living environment (P < 0.001), public environment (P < 0.001) and disability type (significant differences were found in visual and hearing disabilities compared with physical disability, P < 0.05) were key predictors of satisfaction with assistive device use. The impact of public environment on satisfaction was exerted through two indirect mediating paths: mediating effect via perceived usefulness of assistive devices (ind₁ = 0.357, 95%CI 0.279 to 0.437, P < 0.001), contributing approximately 70% of the total indirect effect; mediating effect via home living environment (ind₂ = 0.129, 95%CI 0.006 to 0.242, P = 0.038), contributing approximately 25% of the total indirect effect. ConclusionThere is a structural imbalance between assistive device use and demand in Sichuan-Chongqing region. People with psycho-intellectual disabilities are most likely to be excluded from the service chain because they neither perceive need nor access information. Education exerts a robust positive effect on both adoption and satisfaction, so training content must be tailored to different educational levels. Satisfaction is shaped by disability type, device usefulness and environmental factors. Future product development should therefore integrate functional and psychosocial dimensions. Priority should be given to micro-scale home-and-community accessibility retrofits before extending upward to public transportation and employment settings, to maximize the cost-effectiveness of limited funds.

Diabetes, hyperlipidemia, and hyperuricemia have emerged as global chronic metabolic disorders posing significant public health challenges. Edible medicinal plants demonstrate multitarget regulatory effects and favorable safety profiles in the management of chronic metabolic diseases, owing to their bioactive compounds and nutritional synergy. Radix Astragali (RA), a traditional Chinese medicine with medicine–food homology, has a long history of application in China. Based on a review of relevant literature, this article discusses the historical background, modern research, therapeutic functions, and mechanisms of RA in the treatment of chronic metabolic diseases. Modern studies have shown that RA contains a variety of bioactive components and demonstrates efficacy in managing diabetes, hyperlipidemia, and hyperuricemia. Its mechanisms of action involve modulation of the insulin signaling pathway, regulation of lipid metabolism-related enzyme activity, promotion of uric acid excretion, and other processes. Notably, RA exhibits certain common therapeutic effects across hyperglycemia, hyperlipidemia, and hyperuricemia. Through modulation of the gut microbiota and inhibition of inflammatory pathways, RA exerts synergistic, multitarget effects that improve metabolic disorders associated with chronic metabolic diseases.

ObjectiveTo investigate the association between the maintenance treatment of modified Yiqi Huoxue Jiedu Formula （益气活血解毒方） or poly ADP ribose polymerase （PARP） inhibitors and the recurrence and metastasis of advanced ovarian cancer. MethodsA case-control study design was employed， dividing patients with advanced ovarian cancer into two groups based on the occurrence of recurrence and metastasis following first-line maintenance treatment. Patients with recurrence and metastasis comprised the case group， while those without recurrence and metastasis served as the control group. The previous first-line maintenance treatment method was set as the exposure factor in the study （with the use of modified Yiqi Huoxue Jiedu Formula defined as exposed and PARP inhibitors defined as unexposed）. Basic information was collected for both groups， including the achievement of satisfactory R0 surgery， age， stage， neoadjuvant chemotherapy， lymph node metastasis， germline BRCA1/2 mutations， homologous recombination deficiency positivity， first-line maintenance treatment method （modified Yiqi Huoxue Jiedu Formula or PARP inhibitors）， and CA125 levels after the last chemotherapy. The baseline data of the two groups were assessed for differences. If there exists difference， a 1∶1 nearest neighbor matching method was used for propensity score matching. Univariate and multivariate logistic regression analyses were employed to evaluate the association between the modified Yiqi Huoxue Jiedu Formula or PARP inhibitors and the recurrence and metastasis of ovarian cancer. ResultsA total of 201 patients with advanced ovarian cancer were included， with 97 in the case group and 104 in the control group. Both groups showed statistically significant differences in R0 surgery， stage， neoadjuvant chemotherapy， and CA125 levels after the last chemotherapy （P＜0.05）， indicating baseline imbalance. After propensity score matching， there were 71 patients in both the case and control groups， achieving baseline balance （P＞0.05）. Univariate logistic regression analysis indicated that the achievement of satisfactory R0 surgery （P = 0.006）， disease stage （P = 0.001）， the use of neoadjuvant chemotherapy （P = 0.024）， treatment modality （P = 0.006）， and CA125 levels after the last chemotherapy （P = 0.013） were associated with the recurrence and metastasis of ovarian cancer. Multivariate logistic regression analysis revealed that disease stage was an independent influencing factor for the recurrence and metastasis of ovarian cancer （P = 0.030）， whereas the P-value for the correlation between first-line maintenance treatment and ovarian cancer was 0.188. ConclusionFirst-line maintenance treatment of ovarian cancer patients with the use of modified Yiqi Huoxue Jiedu Formula or PARP inhibitors does not correlate with the recurrence and metastasis of ovarian cancer.

ObjectiveTo analyze the distribution of traditional Chinese medicine （TCM） syndrome elements in patients with immune-related adverse events （irAEs） associated with malignant tumor immunotherapy and to explore the influencing factors for the occurrence of irAEs. MethodsClinical data were retrospectively collected from malignant tumor patients treated with programmed death-1 （PD-1） inhibitors， including demographic information， tumor history， duration of immunotherapy， occurrence of irAEs， types and grades of irAEs （G1-G5）， and TCM four-diagnostic information. Patients were divided into irAEs group and the non-irAEs group based on the occurrence of irAEs. Propensity score matching （PSM） at a 1∶2 ratio was performed to balance baseline characteristics between groups. Syndrome elements before treatment and cumulative contributions of syndrome elements before and after irAEs onset were evaluated using the "Syndrome Elements Differentiation Scale". Logistic regression analysis was conducted to identify factors associated with the occurrence of irAEs. The use of glucocorticoids in the irAEs group was also analyzed. ResultsAfter 1∶2 matching， 59 patients were included in the irAEs group and 118 were in the non-irAEs group. No statistically significant differences were found between groups in terms of age， gender， primary tumor site， pathological type， or tumor stage （P＞0.05）. Patients in the non-irAEs group were more likely to have received targeted therapy， while the irAEs group had a longer duration of immunotherapy and a higher rate of positive programmed death-ligand 1 （PD-L1） expression （P＜0.05）. In total， 72 irAEs events occurred among 59 patients， with an overall incidence rate of 19.4% （59/304） and a grade 3~5 incidence rate of 6.8% （4/59）， mainly presenting as cardiotoxicity， nephrotoxicity， and pneumotoxicity.Before immunotherapy， the top three syndrome elements in the irAEs group were spleen （71.2%， 42/59）， kidney （42.4%， 25/59）， and lung （39.0%， 23/59）. For the pathogenic nature elements， yin deficiency （52.5%， 31/59）， phlegm （40.7%， 24/59）， and dampness （35.6%， 21/59） ranked highest. Compared to the non-irAEs group， the distribution of spleen， kidney， liver， yin deficiency， and qi deficiency elements showed significant differences in the irAEs group （P＜0.05）. After the occurrence of irAEs， the cumulative contributions of spleen， lung， stomach， heart， yin deficiency， qi deficiency， and yang hyperactivity elements increased significantly （P＜0.05）. Multivariate Logistic regression analysis indicated that duration of immunotherapy， spleen syndrome element， kidney syndrome element， liver syndrome element， yin deficiency element， and qi deficiency element were independent risk factors for irAEs （P＜0.05 or P＜0.01）. Among the irAEs patients， 15 received glucocorticoid combined with TCM treatment， while 6 received glucocorticoid therapy alone. Patients receiving combined treatment required lower doses and shorter courses of glucocorticoids compared to those treated with glucocorticoids alone （P＜0.05）. ConclusionIn malignant tumor patients， spleen， kidney， lung， yin deficiency， phlegm， dampness， and qi deficiency are the predominant syndrome elements before and after the occurrence of irAEs. However， elements such as heat and qi stagnation significantly increase after irAEs onset. Duration of immunotherapy， spleen， kidney， liver syndrome elements， yin deficiency， and qi deficiency are independent risk factors for the development of irAEs.

Objective To evaluate the evidence about impact of physical activity(PA)on glycemic control and related health out-comes in patients with type 2 diabetes mellitus(T2DM).Methods Adhering to PRISMA guideline,systematic reviews and meta-analyses published between 2017 and 2024 were retrieved from the databases such as Medline,Embase and Cochrane Library.Two researchers independently ex-tracted data and assessed the quality using AMSTAR2.The included systematic reviews were systematically re-viewed.Results Eight systematic reviews were included,with six rated as high quality and two as low quality.Various forms of PA interventions,such as aerobic exercise,resistance training,combined training and high-intensity interval train-ing,might significantly reduce glycated hemoglobin,enhance cardiorespiratory fitness,lower cardiovascular risk factors(such as body mass,blood pressure and blood lipids),and decrease the risk of diabetes-related complica-tions and mortality in T2DM patients.Combined training and high-intensity training seemed to be better.Profes-sionally supervised PA was more effective.Conclusions Regular and multimodal PA is effective on glycemic control,and cardiovascular and metabolic risk factors in T2DM patients.It is advocated an individualized,diversified,adequately dosed(encouraging higher total dos-es),intensity-appropriate(promoting higher intensity),combined-mode and supervision-integrated PA strategies.

Objective To investigate the prognostic role of serum beta 2-microglobulin(β2M)as a systemic inflammatory biomarker in hospitalized patients with exacerbation of COPD,compared with other inflammatory biomarkers.Methods We retrospectively analyzed hospitalized patients with exacerbated COPD as the first diagnosis at Beijing Chao-Yang hospital,P.R.China,from December 31,2012 to December 28,2017.Serum β2M levels,laboratory and clinical indexes were measured or collected on admission,and all patients were followed up for 90 days.The prognostic performance of β2M was compared with the neutrophils-lymphocytes ratio(NLR),C-reactive protein values(CRP)and white blood cell(WBC)using MedCalc.Results For 30-day mortality,β2M,NLR,and CRP showed significant predictive value(all P<0.001)and were better than WBC(P=0.044,0.003 and 0.030,respectively)in hospitalized patients with exacerbated COPD,while WBC had no predictive significance.For 90-day mortality,β2M,NLR,CRP,and WBC were all statistically significant,but only NLR outperformed WBC(P=0.004).No significant differences were observed among β2M,NLR,and CRP.Conclusion As a systemic inflammatory biomarker,serum β2M was a useful prognostic biomarker for short-term death in hospitalized patients with COPD exacerbations.It performed slightly better than NLR and CRP for 30-day mortality prediction and slightly superior to CRP and slightly inferior to NLR for 90-day mortality prediction.

Objective:To analyze the current status and trend of the mortality burden of cardiovascular disease in China from 2010 to 2021.Methods:Data related to cardiovascular disease mortality and disability-adjusted life year (DALY) were extracted from the Global Burden of Disease Study 2021 (GBD2021) database. The age-standardized mortality rate and DALY rate were calculated, using the 2021 world standard population estimated by GBD2021. Joinpoint 5.2.0 software was used to calculate the mortality rate, standardized mortality rate, DALY rate, standardized DALY rate, annual percent change (APC), average annual percent change (AAPC), and 95% CI of cardiovascular disease in China from 2010 to 2021. Results:The mortality rate of cardiovascular disease was 357.44/100 000, and the age-standardized mortality rate was 280.11/100 000 in China in 2021. The DALY rate was 7 043.33/100 000, and the age-standardized DALY rate was 5 120.06/100 000. From 2010 to 2021, the mortality rate and DALY rate of cardiovascular disease in China showed an upward trend (AAPC was 1.58% and 0.83%, respectively, both P<0.05), and the standardized mortality rate and standardized DALY rate showed a downward trend (AAPC was -2.13% and -2.02%, respectively, both P<0.05). The mortality burden of cardiovascular disease was higher in males (mortality rate 392.80/100 000, DALY rate 8 156.19/100 000) than in females (mortality rate 320.38/100 000, DALY rate 5 876.87/100 000). With the increase older in age, the mortality burden of cardiovascular disease in China decreased first and then increased. China ranked high in the mortality burden of cardiovascular disease among G20 member countries. Conclusions:The death burden of cardiovascular disease is serious in China. The mortality rate and DALY rate of cardiovascular disease in China showed an increasing trend from 2010 to 2021, and the standardized mortality rate and standardized DALY rate of cardiovascular disease ranked high in G20 member countries. The death burden of cardiovascular disease was more serious in men and the elderly. It is necessary to develop more comprehensive prevention, treatment, and rehabilitation measures for men and the elderly to reduce mortality and disability rates, decrease the disease burden, and improve the quality of life.

BACKGROUND:Research has shown that vanillic acid has anti-inflammatory and anti-oxidative stress effects,but it is unclear whether it has a protective effect on endplate chondrocytes.OBJECTIVE:To explore the effect and mechanism of vanillic acid on endplate chondrocytes under inflammatory microenvironment.METHODS:(1)Primary endplate chondrocytes were isolated from the intervertebral disc of SD rats and identified by toluidine blue staining and collagenⅡ immunofluorescence.(2)The CCK-8 assay was employed to detect the effects of interleukin-1β and vanillic acid on the proliferation activity of endplate chondrocytes,in order to determine the concentration of vanillic acid for subsequent cell treatment.(3)An inflammatory microenvironment was simulated by adding 10 ng/mL interleukin-1β to the culture medium,and the endplate chondrocytes were treated with low,medium,and high mass concentrations of vanillic acid.The expression levels of inflammatory markers and extracellular matrix proteins were detected by western blot assay and immunofluorescence.(4)The expression of nuclear factor κB signaling pathway-related proteins was detected by western blot assay.RESULTS AND CONCLUSION:(1)The morphology of endplate chondrocytes in adherent culture was pike or triangular in shape,positive for toluidine blue staining and immunofluorescence for collagen Ⅱ,indicating that the experimentally extracted cells were endplate chondrocytes.(2)The CCK-8 assay results showed that treatment with 2.5,5,10,and 20 μg/mL vanillic acid for 24 hours did not significantly inhibit the proliferation of endplate chondrocytes.Compared with the interleukin-1β group,the viability of endplate chondrocytes treated with 5,10,and 20 μg/mL vanillic acid for 24 hours was significantly increased(P＜0.05).Therefore,5,10,and 20 μg/mL vanillic acid was selected as the low,medium,and high dose groups for subsequent treatment of endplate chondrocytes.(3)Compared with the model group(complete medium containing 10 ng/mL interleukin-1β),the expression of NOD-like receptor thermal domain associated protein 3(NLRP3),matrix metalloproteinase 13,matrix metalloproteinase 3,and tumor necrosis factor alpha protein in the endplate chondrocytes of the low,medium,and high doses of vanillic acid groups were significantly reduced(P＜0.05).(4)Compared with the model group,the protein expression of aggrecan and collagen Ⅱ in the endplate chondrocytes of the low,medium,and high dose groups of vanillic acid significantly increased(P＜0.05).(5)Compared with the model group,the protein expression of phospho-nuclear factor κB and phospho-inhibitor of nuclear factor κB in the endplate chondrocytes of the low,medium,and high dose groups of vanillic acid was significantly reduced(P＜0.05).(6)The above results indicate that vanillic acid may alleviate the inflammatory response and extracellular matrix degradation induced by interleukin-1β in rat endplate chondrocytes by inhibiting the activation of the nuclear factor κB signaling pathway.

Objective:To investigate the surgical effect of total parathyroidectomy combined with calf subcutaneous autotransplantation in the treatment of secondary hyperparathyroidism.Method:From Dec 2018 to Dec 2022,31 patients with secondary hyperparathyroidism who underwent total parathyroidectomy combined with calf subcutaneous autotransplantation in our hospital were selected to analyze the therapeutic effect.Results:All 31 operations were successfully completed.A total of 120 parathyroid glands were removed,including 27 cases(87.10%)with 4 parathyroid glands and 4 cases(12.90%)with 3 parathyroid glands.The average length of hospitalization was(15.82±8.74)days.Compared with preoperative parathyroid hormone,the value of parathyroid hormone decreased by more than 50%after 20 min of total parathyroidectomy.The levels of serum calcium,phosphorus,iPTH and calcium-phosphorus product at each time point after operation were significantly lower than those before operation(P＜0.01).The symptoms of joint pain was significantly improved in all patients after operation.During the postoperative follow-up of 31 patients,1 patient was confirmed to have graft recurrence at 6 months after operation,which was surgically removed.Conclusion:Total parathyroidectomy combined with calf subcutaneous autotransplantation can effectively treat secondary hyperparathyroidism and significantly improve the quality of life.
