Objective: Patients with atherosclerotic cardiovascular disease (ASCVD) following percutaneous coronary intervention (PCI) are classified as very-high-risk individuals in cardiovascular disease (CVD) risk stratification. The distribution pattern of traditional Chinese medicine (TCM) syndromes in this patient population, as well as its association with blood lipid profiles and clinical prognosis, remains unclear. The present prospective cohort study aims to investigate these correlations, thereby providing insights to enrich the research fields. Methods: We enrolled consecutive patients with ASCVD who underwent PCI at the Integrated Cardiology Unit of China-Japan Friendship Hospital between September 1, 2020 and December 31, 2022. Demographics and clinical characteristics, signs and symptoms defining each TCM syndrome, and fasting venous blood samples were collected at baseline and follow up or upon major adverse cardiovascular events (MACEs). We analyzed the correlation between TCM syndromes, blood lipid profiles, and MACEs, and developed a new joint prognostic model incorporating both TCM syndromes and blood lipids using logistic regression. The analyses were based on detailed baseline and one-year follow-up data. Results: A per-protocol analysis was performed on 586 patients with complete data ultimately. During the one-year follow-up, 174 patients (29.69%) experienced a MACE. We performed statistical analyses on comorbidities, medication, and biochemical indicators across groups defined by TCM syndrome differentiation. When comparing different TCM syndromes, no significant differences were found in age, body mass index (BMI), history of revascularization, comorbidities, family history of CVD, smoking or drinking, or statin intensity (P > 0.05). Patients with intertwined phlegm and blood stasis syndrome exhibited significantly higher levels of total cholesterol (TC, 5.27 ± 1.18 mmol/L, P < 0.001), triglyceride (TG, 1.96 ± 1.33 mmol/L, P = 0.008), low-density lipoprotein cholesterol (LDL-C, 3.35 ± 0.79 mmol/L, P < 0.001), and high-density lipoprotein cholesterol (HDL-C, 1.24 ± 0.81 mmol/L, P < 0.001) compared with those with other TCM syndromes combined. A multivariable logistic regression model was constructed to predict MACEs. The model included TCM syndrome type [with intertwined phlegm and blood stasis as a predictor, adjusted odds ratio (OR) = 1.413, 95% confidence interval (CI): 0.517 – 3.864, P = 0.501], age (adjusted OR = 0.97, 95% CI: 0.955 – 1.001, P = 0.057), male gender (adjusted OR = 0.698, 95% CI: 0.416 – 1.170, P = 0.173), TC (adjusted OR = 1.004, 95% CI: 0.513 – 1.965, P = 0.990), and LDL-C (adjusted OR = 5.825, 95% CI: 2.214 – 15.326, P < 0.001). This model demonstrated good discriminatory ability for MACEs in post-PCI ASCVD patients [the area under the receiver operating characteristic (ROC) curve (AUC) = 0.865, 95% CI: 0.816 – 0.914]. Conclusion The intertwined phlegm and blood stasis TCM syndrome is associated with a distinct atherogenic lipid profile characterized by elevated levels of TC and LDL-C. The prognostic model that incorporates this TCM syndrome type along with conventional lipid parameters (TC and LDL-C) shows good discriminatory ability for predicting MACEs in ASCVD patients after PCI, underscoring the potential clinical utility of integrating TCM syndrome differentiation into CVD risk assessment.

ObjectiveTo explore the spatial distribution patterns of flavonoid glycosides in Epimedium sagittatum and the influences of environmental factors on the accumulation of these components. MethodsThe spatial statistical analysis and GeoDetector model were used to analyze the distribution patterns of epimedin A，epimedin B，epimedin C，icariin，and total flavonoid glycosides in E. sagittatum samples from 92 different production areas in 36 cities of 13 provinces/municipalities/autonomous regions of China，as well as the effects of 28 environmental factors on the accumulation of each component. ResultsThe average content of flavonoid glycosides 64 （69.56%） producing areas and 30 （83.33%） cities met the quality standard of no less than 1.50% of total flavonoid glycosides in the 2020 edition of Chinese Pharmacopoeia.Epimedin A，epimedin B，epimedin C，icariin，and their sum showed significantly high accumulation.The hot spots regions of epimedin A and epimedin B were similar with each other，mainly located in western Hunan，eastern Hubei，eastern Guizhou，and northern Guangxi.The common hot spot areas of epimedin C and total flavonoid glycosides were in western and southwestern Hunan，southern Henan，northern Anhui，eastern Guizhou，and southern Chongqing.The hot spots areas of icariin were in southern Chongqing，western Hunan，and eastern and northeastern Guizhou.The interactions between environmental factors had stronger explanatory power for the accumulation of components than single factors.The strongest single factor and interactive factor affecting the accumulation of epimedin C were precipitation of wettest quarter （q=0.16） and its interaction with temperature seasonality （q=0.35），respectively.The strongest single factor influencing both the accumulation of icariin and total flavonoid glycosides was the precipitation of coldest quarter （q equals 0.15 and 0.22，respectively）.The strongest interactions were observed between precipitation of coldest quarter and gravel content （q=0.34），as well as between precipitation of coldest quarter and aspect （q=0.35）. ConclusionThirteen cities，including Zhumadian and Nanyang in Henan，Huaihua，Shaoyang，and Zhangjiajie in Hunan，and Zunyi，Qiandongnan，and Tongren in Guizhou，were hot spots of total flavonoid glycosides in E.sagittatum.Precipitation，gravel content，temperature seasonality，and aspect significantly influence the accumulation of flavonoid glycosides in E.sagittatum.This study provides reference for the utilization and production zoning of E.sagittatum.

Objective To explore the effect of plasma-activated gas(PAG)in promoting wound healing.Methods The pro-healing effect of PAG was explored by testing the effectiveness of PAG in promoting cell proliferation and healing of infected wounds.Cell proliferation assay:five different cells(i.e.,HSF,IHSMC,WPMY-1,HaCaT,and HFF)in logarithmic growth phase were inoculated into culture plates.After the cells grew adherently to the wall,the different cells were each grouped experimentally using a suitable time gradient.After the cells were treated with PAG for different time,their activity was detected by CCK-8 method.Animal infected wound healing assay:a wound of about 1.5 cm × 1.5 cm in size was created on the back of SD rats with sterile tweezers and scissors,and then the wound was infected with P.Aeruginosa with A600nm=6.5.After the infection was completed,the wounds were treated with PAG at regular intervals,and the experiment groups were subdivided according to the different treatment durations.Wound healing photographs and changes in relative wound area were used as indicators of healing performance.Results Cell proliferation assay:PAG treatment was effective in promoting cell proliferation for a reasonable period of time,while overdose led to cell death.Therefore,the dose of cells treated with plasma activation gas was defined as=W/N(J/cell),where W is the work consumed by the activation gas device during the treatment process and N is the number of cells.The three indexes(starting dose,optimal dose and safe dose range)were used to characterize the proliferative effect of PAG.Animal infected wound healing assay:the experimental groups all showed accelerated wound healing,so the optimal treatment time was used to characterize the pro-healing effect of PAG.The sterilization mode played a primary role,with an optimal treatment time of 2 min,and the pro-healing mode played a secondary role.The treatment conditions with the best overall healing effect were 2 min for the sterilization mode and 1 min for the pro-healing mode.Conclusion PAG has the effect of promoting cell proliferation and infected wound healing,and indicators can be summarized to quantitatively describe its effect,which is conducive to further standardization of PAG research and clinical utility.

Objective:To present an evaluation indicator system for access to cancer screening services.Methods:The evaluation indicator pool was constructed through a scoping review. The theoretical framework was constructed based on the multi-source indicators, and the qualitative expert consultation method was employed to form the initial version of the three-level evaluation indicator system. Delphi expert consultation method was conducted in two rounds to evaluate the relevance, importance, and availability of the proposed evaluation indicator system. The expert positive coefficient, authority coefficient, coordination degree of expert opinions, and concentration of expert opinions were subjected to analysis. Subsequently, the three-level evaluation indicator system for access to cancer screening services was adjusted and determined based on the boundary value method and the open opinions of experts. Finally, the combination weight method was employed to determine the weight.Results:The initial version of the indicator system comprised 3 primary (first-level) indicators, 11 secondary (second-level) indicators, and 46 tertiary (third-level) indicators. Delphi expert consultation was conducted for the initial version, and 17 experts ultimately completed it, exhibiting a positive coefficient of 100% and an authority coefficient of 0.87. In comparison to the initial round of consultation, Kendall's W coefficient ranges (0.15-0.43, all P<0.05) of relevance, importance, and availability scores for each tertiary indicator in the second round exhibited an improvement. The analysis of the importance dimension indicates that expert opinions are also more concentrated, as evidenced by an increase of 8.5% and 7.0% in the proportion of the tertiary indicators with an arithmetic mean above 8 and a full mark ratio above 0.5, respectively. The final evaluation indicator system comprises three primary indicators, with the weights of structure evaluation, process evaluation, and outcome evaluation being 0.338, 0.378, and 0.285, respectively. It also comprises 11 secondary indicators and 45 tertiary indicators. Conclusions:The evaluation indicator system developed in this article can be an effective evaluation tool for quantitative comparison of access to cancer screening services across different populations, cancer types, and before and after intervention. Furthermore, it is recommended that the system undergo continuous optimization concerning its application.

Objective:To investigate the correlation between the expression level of glypican-6 (GPC6) in gliomas and the prognosis of patients, as well as the effect of GPC6 on the proliferation of glioma cells in vitro.Methods:The transcriptome sequencing (RNA-seq) data of GPC6 gene and clinical data of glioma patients were downloaded from The Cancer Genome Atlas (TCGA) database. A total of 667 patients were enrolled, and the median FPKM value of GPC6 RNA-seq was used to distinguish the low and high expression of GPC6 gene. Kaplan-Meier method was used to analyze the overall survival (OS) of GPC6 high and low expression groups in 664 patients with survival data, and log-rank test was used for inter group comparison. The postoperative tumor tissue chips were retrospectively collected from glioma patients who underwent surgery from February 2008 to October 2011, immunohistochemistry (IHC) was used to detect the expression of GPC6 protein in 147 samples, and semi-quantitative scoring ≥ 4 points or not was used to distinguish the high and low expression of GPC6 protein based on the proportion of positive cells and staining intensity. The distributions of patients with high and low expression of GPC6 protein in tumor tissues were compared between different clinical pathological features in 147 patients, and Kaplan-Meier method was used to analyze the overall survival and disease-free survival (DFS) of patients in the GPC6 protein high and low expression groups; the risk factors that affect poor OS and DFS in patients were analyzed using univariate and multivariate Cox proportional hazards models. The human glioma U251 cells were infected with lentivirus packaged with GPC6 small interfering RNA and lentivirus packaged with unrelated control sequences, namely ShGPC6 group and ShCtrl group, respectively; green fluorescent cells were counted daily and the cell proliferation fold was calculated for 5 days, and the cell proliferation curve was plotted.Results:In TCGA database, the median FPKM value of 667 glioma patients was 225.66. The median FPKM value of GPC6 gene in 515 World Health Organization (WHO) classification low-grade glioma patients was lower than that in 152 high-grade glioma patients (201.10 vs. 347.92), and the difference was statistically significant ( Z = 5.36, P < 0.001); the OS of patients in GPC6 low expression group (332 cases) was better than that in GPC6 high expression group (332 cases), and the difference was statistically significant ( P < 0.001). IHC staining of the tissue chip showed that GPC6 protein was mainly expressed in the cytoplasm and nucleus of glioma cells; high expression of GPC6 protein accounted for 31.3% (46/147) of patients. Among patients who died, relapsed, had high grading, had survival time ≤ 84 months, and had positive epidermal growth factor receptor, the proportion of patients with GPC6 protein high expression was relatively higher, and the differences were statistically significant (all P < 0.05). There were no statistically significant differences in the proportions of GPC6 protein high expression patients among patients with different genders, age ≤ 43 years old, Ki-67 positivity, and programmed death receptor ligand 1 positivity (all P > 0.05); compared to the GPC6 low expression group (101 cases), the GPC6 protein high expression group (46 cases) had worse overall survival (median OS time: 57.0 months vs. not reached) and DFS (median DFS time: 33.0 months vs. not reached), and the differences were statistically significant (both P < 0.001). Multivariate Cox regression analysis showed that high expression of GPC6 protein (high expression vs. low expression, HR = 1.86, 95% CI: 1.04-3.31, P = 0.036) was the independent risk factor for poor OS in glioma patients, but the expression level of GPC6 protein was not the independent influencing factor for DFS (high expression vs. low expression, HR = 1.55, 95% CI: 0.95-2.53, P = 0.077). After infecting U251 cells with recombinant lentivirus for 3 days, reverse transcription polymerase chain reaction detection showed that the relative expression level of GPC6 mRNA in the ShGPC6 group was lower than that in the ShCtrl group, and the difference was statistically significant ( P < 0.001), the knockdown efficiency of GPC6 reached 79.32%; under the fluorescence microscope, the number and intensity of fluorescence positive U251 cells in the ShCtrl group increased day by day after infection with recombinant lentivirus, while there was no significant change in the ShGPC6 group; starting from the second day, the proliferation rate of U251 cells in the ShCtrl group was higher than that in the ShGPC6 group, and the differences were statistically significant (all P < 0.01). Conclusions:High GPC6 expression level may associate with the high risk of death in glioma patients, and high GPC6 expression may promote the proliferation of glioma cells.

Objective To analyze the causal relationship between brain resting state functional magnetic resonance imaging(rsfMRI)network and myocardial infarction using the Mendelian randomization(MR)research method.Methods Four analytical methods of MR[inverse-variance weighted(IVW),weighted median method(WME),weighted mode method,and MR-Egger method]were used to conduct a two-way two-sample analysis between 191 types of rsfMRI phenotypes of the brain(34 691 types)and myocardial infarction.And based on the aggregated analysis of genome-wide association studies(GWAS)data,MR was used to explain the causal relationship between the two.Then,the IVW method was used for analysis and research as the main result,and other analytical methods were used as supplementary analyses.Finally,the credibility of the results was verified by using sensitivity analysis.Results The neural connection activities located at the edge of the fusiform gyrus of the temporal lobe and the default mode network[odds ratio(OR)=1.260,95%confidence interval(95%CI)1.120-1.420,P<0.001]may increase the risk of myocardial infarction.In addition,the motor and subcortical cerebellar networks located in the posterior central gyrus,anterior central gyrus,and cerebellum(OR=0.770,95%CI was 0.680-0.880,P<0.001),and the subcortical cerebellar and motor networks located in the cerebellum and paracentric lobules(OR=0.810,95%CI was 0.720-0.900,P<0.001)and the neural connection activities of the motor and subcortical cerebellar networks located in the posterior central gyrus,anterior central gyrus and subcortex(OR=0.730,95%CI was 0.630-0.840,P<0.001)were associated with a reduced risk of myocardial infarction.Sensitivity analysis showed that the research results were reliable,and after the reverse MR study,it was confirmed that there was no reverse causal association between the two.Conclusion The network signals located at the edge of the fusiform gyrus of the temporal lobe and in the default mode may be potential risk factors for myocardial infarction;the motor and subcortical cerebellar networks located in the posterior central gyrus,anterior central gyrus and cerebellum,as well as the subcortical cerebellar and motor networks located in the cerebellum and paracentric lobules,and the neural connection activities of the motor and subcortical cerebellar networks located in the posterior central gyrus,anterior central gyrus and subcortex may be potential protective factors,providing new ideas for the prevention and treatment of myocardial infarction.

Objective:To evaluate the efficacy and safety of the pegaspargase, etoposide, methotrexate, and dexamethasone (PEMD) regimen in patients with early-stage nonupper respiratory digestive tract or advanced extranodal natural killer/T-cell lymphoma (ENKTL) .Methods:This retrospective analysis included 38 patients with newly diagnosed early-stage non-upper respiratory digestive tract or advanced ENKTL who received PEMD regimen for induction chemotherapy at the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2022. Survival outcomes and prognostic factors were examined by Kaplan-Meier, and the Log-rank test was used to compare survival.Results:The study population had a median age of 48 years (range, 26-72 years) and included 30 males (78.9%) and 8 females (21.1%). 7 patients’ age >60 years (18.4%). The Eastern Cooperative Oncology Group (ECOG) performance score was >1 in 7 patients (18.4%) ; 20 patients (52.6%) had elevated lactate dehydrogenase levels; and 37 patients (97.4%) exhibited extranodal involvement. Using the Ann Arbor staging system, 37 patients (97.4%) were classified as stage Ⅲ-Ⅳ. The median number of treatment cycles was 5 (1-6), and the median follow-up duration was 60 months (24 - 101 months). Interim efficacy assessment revealed an overall response rate of 52.7%. At 2 and 4 years, the progression-free survival (PFS) rates were 34.2% (95% CI 22.0%-53.2%) and 25.5% (95% CI 14.7%-44.4%), respectively, and the overall survival rates were 50.0% (95% CI 36.4%-68.7%) and 45.5% (95% CI 31.4%-65.7%), respectively. The risk factors for worse PFS were ECOG performance score >1 [ HR=3.711 (95% CI 1.494-9.218), P=0.005]; bone marrow infiltration [ HR=2.251 (95% CI 1.026 - 4.938), P=0.043]; and Prognostic Index for Natural Killer/T-Cell Lymphoma score of 3 - 5 [ HR=2.350 (95% CI 1.009 - 5.476), P=0.048]. Multivariate analysis identified ECOG performance score >1 as an independent risk factor for PFS [ HR=7.971 (95% CI 2.222 - 28.591), P=0.001]. The main adverse effect was anemia in 31 patients (81.6%) . Conclusion:The PEMD regimen was safe and effective for patients with newly diagnosed early-stage non-upper respiratory digestive tract or advanced ENKTL.

Objective To investigate the effects of extracellular vesicles(EVs)derived from synovial fluid of rheumatoid arthritis(RA)patients on angiogenesis of human umbilical vein endothelial cells,and to preliminarily explore the underlying mechanisms.Methods Synovial fluid samples of knee joint were collected from 20 patients with RA and 20 patients with osteoarthritis(OA)in this study.EVs were purified using ultracentrifugation.The morphology and size of EVs were observed by transmission electron microscopy and nanoparticle tracking analysis.CD9,CD63,cytochrome c(Cyt-c),vascular endothelial growth factor(VEGF),lysyl oxidase(LOX),matrix metalloproteinase 2(MMP2),tumour necrosis factor alpha(TNF-α),transforming growth factor beta1(TGF-β1)in EVs were detected using Western blot.Human umbilical vein endothelial cells(HUVEC)were treated with the EVs.The growth,migration and angiogenesis of HUVEC were observed by CCK8 assay,TranswellTM chamber assay,scratch test and matrigel angiogenesis assay,respectively.The effect of EVs on the PI3K/AKT pathway in HUVEC was assessed using Western blot.Results Both EVs from RA synovial fluid(RA-EVs)and OA synovial fluid(OA-EVs)were cup-shaped,mainly between 30-400 nm in diameter,expressing CD63 and CD9,but not Cyt-c.RA-EVs carried more VEGF,LOX,MMP2,TNF-α and TGF-β1 than OA-EVs.Compared with the OA-EVs intervention,RA-EVs significantly promoted the proliferation,migration,and angiogenesis of HUVECs,as well as upregulated PI3K/AKT phosphorylation.The inhibitor of PI3K suppressed angiogenesis induced by EVs.Conclusion EVs in synovial fluid of RA carried more cytokines and enzymes that related angiogenesis and inflammation.These EVs exert their pro-angiogenic effects by activating the PI3K/AKT pathway,then contributing to the pathological progression of RA.

Objective To evaluate the results of anorectal dynamics in patients with severe rec-tocele.Methods A retrospective analysis was conducted on the clinical data of 38 patients defini-tively diagnosed with severe rectocele at the pelvic floor center of the anorectal department of Nanjing Hospital of Traditional Chinese Medicine from January 2020 to January 2023.All patients underwent anorectal manometry,and the results of anorectal dynamics were analyzed.Results A total of 15 pa-tients(39.47％)had elevated anal resting pressure(ARP),20(52.63％)had normal ARP,and 3(7.89％)had decreased ARP.Five patients(13.16％)had elevated maximum anal sphincter pressure(MASP),9(23.68％)had normal MASP,and 24(63.16％)had decreased MASP.Nor-mal defecation relaxation reflex was observed in 15 patients(39.47％),and abnormal defecation re-laxation reflex was observed in 23 patients(60.53％).Ten patients(26.32％)had normal rectal defecation pressure,and 28(73.68％)had decreased rectal defecation pressure.Eleven patients(28.95％)had elevated rectal initial sensory threshold(RIST),27(71.05％)had normal RIST.Fifteen patients(39.47％)had elevated rectal defecation sensory threshold,21(55.26％)had normal rectal defecation sensory threshold,and 2(5.26％)had decreased rectal defecation sensory threshold.Three patients(7.89％)had elevated rectal maximum tolerable volume,26(68.42％)had normal rectal maximum tolerable volume,and 9(23.68％)had decreased rectal maximum tolerable vol-ume.ARP was moderately positively correlated with the chronic constipation severity(CSS)score(P=0.007,r=0.429),and abnormal defecation relaxation reflex was moderately negatively correla-ted with the CSS score(P=0.019,r=-0.329).In 3 patients(7.89％),both ARP and MASP were decreased,and both ARP and MASP were elevated in 5 patients(13.16％).Conclusion Pre-operative anorectal dynamics analysis is necessary for patients with severe rectocele to formulate a reasonable individualized surgical plan and postoperative rehabilitation program.

Objective: To evaluate the effects of different surface treatment methods and simulated aging on the roughness, microhardness, and color stability of lithium disilicate glass ceramics(LDC). Methods: The LDC were grouped and performed 5 kinds of surface treatments: control group, polishing group, polishing+polishing paste group, glazing group, polishing+glazing group. The roughness and microhardness of the specimen were measured. Then the specimens were divided into two subgroupswhich were treated with water and staining solution. The specimens were measured color parameters before and after processing. The above data was analyzed. Results: The LDC had changes in surface roughness and microhardness after different surface treatments. The polishing+polishing paste group had the lowest surface roughness, and the surface microhardness of the LDC decreased after glazing. After simulating aging, the difference of color and transparency of the polishing+polishing paste group, glazing group, and polishing+glazing group were the smallest. Conclusion Different surface treatments and simulated aging have a certain impact on the roughness, microhardness, and color stability of LDC. Fine polishing with polishing paste has a comparable anti staining effect to glazing on LDC.
