ObjectiveTo address the limitations of the current quality standard for Polygalae Radix（PR）， which relies on a single component for quality assessment and struggles to holistically control its intrinsic quality， by constructing a comprehensive quality evaluation system integrating "macro-characterization of chemical profile， synchronous quantification of multiple index components， and quantitative analysis of multi-components by single marker（QAMS） for key component groups". This study aims to facilitate the scientific revision of the quality standard for PR. MethodsHigh performance liquid chromatography（HPLC） characteristic chromatograms were established for 11 batches of PR medicinal materials（YZ）， 10 batches of PR decoction pieces（YP）， and 10 batches of licorice-processed PR decoction pieces（ZYZ）， followed by similarity evaluation and identification of common peaks. HPLC-QAMS was developed for xanthones（sibiricaxanthone B， polygalaxanthone Ⅺ， polygalaxanthone Ⅲ） in the characteristic chromatograms. Simultaneously， the external standard method（ESM） was used to determine the contents of the corresponding xanthones and 3，6'-disinapoyl sucrose in YZ， YP， and ZYZ， followed by multivariate statistical analysis and Spearman correlation analysis. ResultsThe similarity between the characteristic chromatograms of 31 batches of PR samples and the reference chromatogram was>0.9. A total of 13 common peaks were identified， and 10 of these peaks were characterized through reference standard comparison. The successfully constructed QAMS method showed that the relative correction factors（RCFs） of sibiricaxanthone B and polygalaxanthone Ⅺ to polygalaxanthone Ⅲ were 0.76 and 0.88， and their relative retention times（RRTs） were 0.85 and 0.97， respectively. The results calculated by the QAMS method showed no significant difference from those obtained by the ESM. According to the limit standard for polygalaxanthone Ⅲ in the 2020 edition of the Pharmacopoeia of the People's Republic of China（hereinafter referred to as the Chinese Pharmacopoeia）， the pass rate of 31 batches of samples was only 19.35%. Multivariate statistical analysis indicated certain compositional differences between different batches of YZ and YP， as well as between YP and ZYZ， with 3，6'-disinapoyl sucrose identified as the main differentiating component. Furthermore， correlation analysis revealed that the content of polygalaxanthone Ⅲ was positively correlated with the contents of sibiricaxanthone B and polygalaxanthone Ⅺ， but showed no association with the content of 3，6'-disinapoyl sucrose. ConclusionIt is recommended that the content limit for polygalaxanthone Ⅲ in YZ，YP and ZYZ be revised to not less than 0.07%， or the total content of polygalaxanthone Ⅲ， sibiricaxanthone B and polygalaxanthone Ⅺ be not less than 0.18%. The newly established triple quality control model of "holistic control via characteristic chromatograms， precise quantification of oligosaccharide esters， and efficient detection of xanthones by QAMS" provides a systematic and precise solution for quality evaluation of PR and similar Chinese herbal medicines.

OBJECTIVE To investigate the neuroprotective effect and mechanism of eleutheroside B （ELB） on Parkinson’s disease （PD） model mice by regulating the IκB kinase β （IKKβ）/nuclear factor-κB （NF-κB） signaling pathway. METHODS Fifty mice were randomly divided into normal control group， model group， positive control group （selegiline hydrochloride， 10 mg/kg）， and ELB low-dose and high-dose groups （80， 160 mg/kg）， with 10 mice in each group. Each group was given relevant medicine or normal saline intragastrically for 14 consecutive days. Starting from the 10th day of administration， the model group and all administration groups were intraperitoneally injected with 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine （MPTP） 30 mg/kg， for five consecutive days to establish the chronic PD model. After the last administration for 24 h， six mice were randomly selected from each group to test their behavioral abilities； detect the levels of interleukin-1β （IL-1β）， IL-10， tumor necrosis factor-α （TNF-α） in brain tissue and their mRNA expressions were measured， and positive expression of tyrosine hydroxylase （TH）， protein expressions of TH， α -synuclein （ α -syn）， ionized calcium-binding adaptor molecule 1 （Iba-1）， as well as phosphorylation levels of IKKβ and NF-κB p65 proteins in the brain tissue were detected. The ultrastructure of neurons in substantia nigra was observed. RESULTS Compared with the model group， rotarod endurance time and climbing score of each administration group （except for the ELB low-dose group） were increased significantly （ P ＜0.05）， while the levels and mRNA expressions of IL-1β， TNF-α， α -syn， and Iba-1， as well as phosphorylation levels of IKKβ and NF-κB p65 proteins in brain tissue were decreased significantly （except for TNF-α in the ELB low-dose group）. Conversely， the level and mRNA expression of IL-10 （except for the ELB low-dose group）， TH positive expression and protein expressions were significantly increased （ P ＜0.05）. Typical neurodegenerative pathological changes， such as neuronal karyopyknosis， mitochondrial swelling and vacuolization， and endoplasmic reticulum dilation， all showed varying degrees of improvement. CONCLUSIONS ELB may exert neuroprotective effects by inhibiting the activation of the IKKβ/NF-κB signaling pathway， alleviating inflammatory responses， reducing abnormal α -syn aggregation and neuronal loss， and further improving motor dysfunction in PD mice.

Antibody-drug conjugates （ADCs） are a novel class of anti-tumor agents composed of a targeted monoclonal antibody， a cytotoxic drug， and a linker connecting the two. They combine the high specificity of antibodies with the potent cytotoxicity of chemotherapeutic agents. Triple-negative breast cancer （TNBC） is characterized by high aggressiveness， elevated risks of recurrence and metastasis， and poor prognosis， largely due to the lack of effective therapeutic targets. This review summarizes the research progress of ADCs in the treatment of TNBC. It has been found that ADCs targeting human epidermal growth factor receptor 2 （such as trastuzumab deruxtecan）， trophoblast cell surface antigen 2 （such as sacituzumab govitecan and datopotamab deruxtecan）， zinc transporter LIV-1 （such as ladiratuzumab vedotin）， HER-3 （such as patritumab deruxtecan）， epidermal growth factor receptor （such as AVID100）， and glycoprotein non-metastatic melanoma protein B （such as glembatumumab vedotin） have all demonstrated promising therapeutic effects against TNBC. Despite challenges including acquired resistance and treatment-related toxicities， ADCs are undoubtedly reshaping the therapeutic landscape for TNBC and are expected to occupy a more central position in TNBC treatment in the future.

Objective To investigate the influencing factors of stroke patients with hypertension and their compliance with antihypertensive drugs, and to provide targeted intervention measures for stroke prevention in hypertensive patients.  Methods Using the method of multi-stage cluster sampling, a total of 59,434 permanent residents aged 40 and above were selected from 48 monitoring sites in 9 cities of Hebei Province from December 2019 to December 2020. Unconditional logistic regression analysis was used to explore the influencing factors of stroke complicated with hypertension and the compliance of patients with antihypertensive drugs.  Results Among the 59 434 subjects, the prevalence rate of stroke was 4.33% and the prevalence rate of stroke complicated with hypertension was 82.47%. The results of univariate analysis showed that the proportion of women, rural areas, dyslipidemia, diabetes, obesity, and people with family history of stroke was higher in stroke patients with hypertension, and the difference was statistically significant (P<0.05). Multivariate logistic regression analysis showed that rural areas, dyslipidemia, diabetes, obesity, and family history of stroke significantly increased the risk of stroke, and the OR (95%CI) values were 1.29 (1.03-1.62), 1.39 (1.12-1.72), 1.58 (1.25-1.99), 1.61 (1.22-2.12) and 1.60 (1.26-2.04), respectively. Among stroke patients with hypertension, 92.71% of patients took antihypertensive drugs. It was found that women's compliance with antihypertensive drugs was good, with an OR (95%CI) value of 1.46 (1.01-2.09).  Conclusion The prevalence rate of stroke complicated with hypertension is high in people aged 40 and above in Hebei Province. Hypertensive people should lower blood lipids, control blood glucose, and lose weight as soon as possible to prevent the occurrence of stroke.

ObjectiveTo investigate the ability of clinically isolated， Helicobacter pylori （H. pylori）-specific gene polymerase chain reaction （PCR）-positive gastric， vaginal， and fecal Candida to release H. pylori. MethodsResuscitate 4 strains of H. pylori -specific 16S rDNA and ureA gene PCR-positive Candida strains isolated in laboratory from clinical sources， including 1 strain of gastric Candida， 1 strain of fecal Candida， 2 strains of vaginal Candida and the standard Candida albicans strain ATCC10231 （Ca10231）. The presence of H. pylori-specific ureA in the 5 strains of Candida isolates was confirmed by PCR. The aforementioned strains of Candida and H.pylori were inoculated into urea medium and cultured in a constant temperature incubator at 37 ℃. The color change of the medium was observed daily. A change in the medium's color from yellow to red indicated the presence of urease activity. Then， the five strains of Candida and H. pylori were co-incubated with the magnetic beads coated with H. pylori antibodies respectively. Scanning electron microscopy （SEM） was employed to observe the presence of bacilli adsorbed on the surface of the magnetic beads. PCR was used to detect the presence of H.pylori-specific 16S rDNA and ureA genes on magnetic beads. ResultsThe PCR analysis of the ureA gene in the four Candida isolates was positive， whereas the Ca10231 strain tested negative. Upon culturing the four Candida isolates on urea medium， the medium color changed from yellow to red which was determined to be urease positive， while the medium containing Ca10231 remained unchanged， which was urease negative. SEM revealed that bacilli could be observed on the surface of magnetic beads co-incubated with the 4 strains of Candida of clinical origin and H.pylori isolate. Specifically， PCR testing of the magnetic beads co-incubated with one vaginal Candida， one gastric Candida and H.pylori isolate showed positive results for the 16S rDNA and ureA genes of H. pylori； however， the PCR tests for the two genes were negative for the magnetic beads co-incubated with the other two Candida isolate. ConclusionThis study demonstrates that H. pylori-specific genes Candida can release H. pylori.

OBJECTIVE To assess the cost-effectiveness of durvalumab combined with chemotherapy as a first-line treatment for advanced biliary tract cancer from the perspective of the Chinese healthcare system. METHODS Using data from the TOPAZ-1 clinical trial， a three-state Markov model comprising progression-free survival （PFS）， progressive disease （PD） and death was developed， with a cycle length of 21 days and a 10-year time horizon. Patients in the observation group received durvalumab in combination with gemcitabine and cisplatin， whereas those in the control group received placebo plus the same chemotherapy regimen. The evaluation indexes were quality-adjusted life year （QALY） and the incremental cost-effectiveness ratio （ICER）. The willingness-to-pay （WTP） threshold was set at three times the 2024 Chinese per capita gross domestic product （GDP） （287 247 yuan/QALY）. The sensitivity analyses， along with scenario analyses， were performed. RESULTS In the base-case analysis， the ICER of observation group compared to control group was 1 166 344.46 yuan/QALY， far exceeding the WTP threshold， indicating that the regimen was not cost-effective. One-way sensitivity analysis identified the PD state utility， discount rate， cost of durvalumab， and PFS state utility as the main drivers of ICER variation. Probabilistic sensitivity analysis showed that， at the above WTP threshold， the probability of the acceeptance of this regimen was 0， further supporting the robustness of the base-case findings. In the scenario analysis， inclusion of a patient assistance program reduced the ICER to 235 885.16 yuan/ QALY， below the above WTP threshold， suggesting cost-effectiveness under this assistance program. However， when applying a regional WTP threshold set at three times the per capita GDP （158 475 yuan/QALY） of Gansu Province （the province with the lowest GDP in China in 2024）， the ICER remained above the threshold， indicating that the regimen was not cost-effective at the regional level. CONCLUSIONS At current pricing， durvalumab plus chemotherapy as a first-line treatment for advanced biliary tract cancer is not cost-effective in China. Although the introduction of a patient assistance program can substantially reduce the ICER and achieve cost-effectiveness at a WTP threshold set at three times the 2024 per capita GDP of China， due to limited affordability in low-income areas， the program remains not cost-effective.

Objective: To compare the effects of high intensity interval training (HIIT) exercise prescription based on machine vision and routine on HIIT the physical and mental health of female college students with simple obesity, so as to provide a basis for the development of weight loss intervention plans for this population. Methods: From August 2023 to February 2024, 115 female college students with simple obesity, selected from Lianyungang Vocational and Technical College and East China Normal University, were randomly divided into a control group ( n =57) and an observation group ( n =58) according to a random number table. The control group received routine HIIT, while the observation group received machine vision based on HIIT exercise prescription (including image acquisition module, image processing module, database management module, backend computer processing and feedback, intelligent evaluation module, which could be customized according to the subjects preferences, providing exercise prescription based on the selected training program and supervised its standardized completion of the training plan). Both were intervened for 12 weeks, 30 minutes each time, once every 2 days, and rest every Sunday. The t-test was used to compare body shape, glucose and lipid metabolism, cardiopulmonary function indicators, anxiety and depression states between two groups before and after intervention. Results: Before intervention, there were no statistically significant differences in physical and mental health status indicators between two groups of female college students ( t =0.13-0.86, all P >0.05). After intervention, body mass indexes, waist hip ratios, body fat percentage, fasting plasma glucose, 2hour postprandial plasma glucose, hemoglobin A1c, triglycerides, total cholesterol, lowdensity lipoprotein cholesterol (LDL-C), anxiety and depression scores were all reduced in both groups ( t-observation =-6.94 to -12.92, t-control =-2.71 to -10.95 ), of which the observation group [(23.46±2.18)kg/m 2, 0.70±0.06, (28.03±3.16)%, (4.55±0.67)mmol/L, (6.03±0.74)mmol/L, (5.10±0.70)%, (1.63±0.31)mmol/L, (4.24±0.58)mmol/L, (2.45±0.43)mmol/L, 35.28±4.76, and 33.03±4.03] were lower compared with the control group [(26.54±2.32)kg/m 2, 0.77±0.06, (30.74±4.38)%, (5.03±0.76)mmol/L, (6.62±0.82)mmol/L, (5.82±0.73)%, (1.98±0.35)mmol/L, (4.95±0.61)mmol/L, (2.88±0.47)mmol/L, 39.18±5.04, and 37.25±4.16] ( t =-7.34, -6.26 , -3.81, -3.59, -4.05, -5.40, -5.68, -6.40, -5.12, -4.27, -5.53)(all P <0.05). After intervention, high density lipoprotein cholesterol, stroke volume, left ventricular ejection fraction, maximum oxygen consumption, volume of tidal, and vital capacity increased in both groups ( t-observation =7.43-18.23, t-control =3.89-10.13), of which the observation group [(1.49±0.22)mmol/L, ( 72.35± 4.69)mL, (68.95±5.10)%, (36.97±3.22)mL/(kg ·( min), (25.29±4.11)mL/(kg · ( min), and (3 374.26±169.54)mL] were higher compared with the control group [(1.23±0.20)mmol/L, (67.32±4.06)mL, (64.83±5.05)%, (33.24±3.14)mL/(kg · ( min), (23.01± 3.58 )mL/(kg · ( min), and (3 197.50±125.81)mL] ( t =6.63, 6.15, 4.35, 6.29, 3.17, 6.34)(all P <0.05). Conclusion HIIT exercise prescription based on machine vision has better effects than routine HIIT on impoving the body shape, glucose and lipid metabolism, cardiopulmonary function of female college students with simple obesity, and also their mental health.

Circulating tumor cells (CTCs) have the ability to sow tumors and can be found in the peripheral blood of patients with precancerous lesions and healthy people. However, CTCs are not currently screened in the donors blood. A large number of allogeneic blood transfusions occurred worldwide each year, and allogeneic blood transfusions expose recipients to the risk of transmission and affect tumors associated with donor CTCs. Although leukocyte filtration can not completely remove tumor cells in the blood, it can effectively reduce the number of white blood cells in the blood and reduce their proliferation ability. Blood irradiation can effectively destroy the DNA of CTCs in the blood, and inhibit the occurrence and metastasis of tumors caused by the infusion of allogeneic blood containing CTCs. Therefore, we should pay attention to the potential risk of CTCs on clinical transfusion, and strengthen the preclinical treatment of blood to avoid donor-related tumor infection in blood recipients due to clinical transfusion.

Objective To investigate the effects of secukinumab combined with E'xian Huaban decoction on traditional Chinese medicine symptom scores and nailfold microcirculation morphology in patients with plaque psoriasis.Methods A total of 120 patients with plaque psoriasis were selected and randomly divided into monotherapy group(n=60)and combination therapy group(n=60).The monotherapy group received secukinumab treatment,while the combination therapy group was treated with secukinumab plus E'xian Huaban Decoction.Clinical therapeutic efficacy,traditional Chinese medicine symptom scores(including skin lesions,pruritus,rough skin,scales and irritabili-ty),relevant scale[Psoriasisarea and Severity Index(PASI),Dermatology Life Quality Index(DLQI)and Visual Analogue Scale(VAS)]scores,inflammatory factors[interleukin-17(IL-17),interleukin-23(IL-23)and vascular endothelial growth factor(VEGF)]levels and nailfold microcircu-lation morphology(loop tube morphology,blood flow state and loop periphery state)were observed in both groups.Results The overall clinical efficacy rate in the combination therapy group was 95.00％,which was significantly higher than 83.33％ in the monotherapy group(P＜0.05).After treatment,traditional Chinese medicine symptom scores(skin lesions,pruritus,rough skin,scales and irritability),inflammatory factors(IL-17,IL-23 and VEGF)levels,scale(PASI,DLQI and VAS)scores as well as loop tube morphology scores,blood flow state scores and loop periphery state scores were signifi-cantly lower compared to pre-treatment values,and these parameters were significantly lower in the combination therapy group than the monotherapy group(P＜0.05).Conclusion Secukinumab combined with E'xian Huaban Decoction can significantly improve clinical symptoms and signs,and enhancing the clinical therapeutic effect.
