OBJECTIVE To investigate the immunotoxicity and potential mechanism of Carthamus tinctorius extract on RBL-2H3 cells via direct induction and induction by sensitized serum prepared with an overdose of the extract. METHODS For direct induction by C. tinctorius extract， RBL-2H3 cells were divided into normal control group （no treatment） and C. tinctorius extract group （10 mg/mL）. For induction by sensitized serum prepared with an overdose of C. tinctorius extract， rats were divided into normal control group （no treatment）， adjuvant-treated group （1 mL adjuvant）， C. tinctorius extract-induced sensitization group （2.04 g/mL）， and ovalbumin （OVA）-induced sensitization group （50 mg/mL）. Sensitization was performed once every other day for a total of 3 times. Morphological changes of RBL-2H3 cells were observed， the degranulated rate of cells was counted， and histamine content was determined； the release rate of β -hexosaminidase （ β -Hex） was calculated， the levels of interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） and intracellular Ca²⁺ concentration were detected. RESULTS Under direct induction by C. tinctorius extract， compared with the normal control group， the volume of cells in the C. tinctorius extract group was significantly reduced and cell density decreased； the degranulation rate of cells， histamine content， β -Hex release rate， IL-6 and TNF-α levels， as well as intracellular Ca²⁺ concentration were all significantly increased （ P ＜0.01）. Under i nduction by sensitized serum prepared with an overdose of C. tinctorius extract， compared with the adjuvant-treated group， the above indicators in the C. tinctorius extract-induced sensitization group and the OVA-induced sensitization group showed consistent changes with those in the C. tinctorius extract group under direct induction， all being significantly elevated （ P ＜0.01）. CONCLUSIONS C. tinctorius extract may affect degranulation of RBL-2H3 cells and promote Ca²⁺ influx accompanied by the release of pro-inflammatory cytokines through two approaches： direct induction and induction by sensitized serum prepared under overdose administration. Its mechanism may be related to the activation of the calcium signaling pathway and the regulation of inflammatory pathways under the synergistic effect of multiple components.

OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics （ 2026 edition ） in response to the challenges faced by such clinics in China， including uneven development， large discrepancies in service specifications， insufficient patient awareness， and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association， the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association， and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association， a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research， current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections： definition and connotation of pharmacist-managed clinics， establishment requirements， implementation and management， post competency， and practical research. Firstly， the definition and connotation included three operational forms of pharmacist-managed clinics （independent mode， physician-pharmacist joint mode， and online pharmacist-managed clinic mode） and classified service modes （specialty-specific， drug-specific， and disease-specific pharmacist-managed clinics）. The establishment requirements were further refined， covering system construction （pharmaceutical service management system， quality control and assessment mechanism）， personnel qualifications （professional credentials， continuing education and professional training， etc）， service recipients， as well as service venues and facilities. Subsequently， the implementation and management of pharmacist-managed clinics were proposed， involving service procedures， intervention measures， documentation and records， patient education and follow-up， humanistic care， as well as risk management and quality control. Finally， post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics， as well as the suggestions on teaching methods； practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment， management， teaching， and research， fill the guideline gap in this field， and can promote the high-quality development of pharmacist-managed clinics.

ObjectiveTo investigate the inhibitory effect of Biejiajian Pills （BJJW） on the growth of liver cancer， as well as its potential mechanism in mediating the AMP-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway through mitochondrial energy metabolism. MethodsHuman hepatoma Huh7 cells were used to establish a nude mouse model of subcutaneous xenograft tumor. A total of 18 tumor-bearing nude mice were randomly divided into model group， BJJW group （2.2 g/kg）， and metformin group （250 mg/kg）， and the corresponding drug was given by gavage for 14 consecutive days. Tumor volume and weight were monitored during the experiment； HE staining was used to observe histopathological changes； the levels of reactive oxygen species （ROS） and adenosine triphosphate （ATP） in tumor tissue were measured； immunohistochemistry and Western blotting were used to measure the expression levels of proteins associated with the AMPK/mTOR pathway. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Tukey’s test was used for further comparison between two groups； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups， and the Dunn’s test was used for further comparison between two groups. ResultsCompared with the model group， the BJJW group had a tumor inhibition rate of 45.73%， with significant reductions in both tumor volume and weight （P<0.01）. Pathological examination showed that compared with the model group， the BJJW group had a significant reduction in the number of tumor cells and the presence of extensive necrosis. Mechanistic studies showed that compared with the model group， the BJJW group had a significant increase in ROS level （P<0.001） and a significant reduction in ATP level （P<0.001）， as well as significant increases in p-AMPK/AMPK ratio （0.81±0.20 vs 0.13±0.04， P<0.01） and p-ULK1/ULK1 ratio （0.69±0.17 vs 0.18±0.13， P<0.01） and a significant reduction in p-mTOR/mTOR ratio （1.34±0.16 vs 3.20±0.62， P<0.01）. ConclusionBJJW may inhibit the growth of liver cancer by inducing mitochondrial energy metabolism dysfunction， increasing the level of ROS， reducing the level of ATP， and activating the AMPK/mTOR signaling pathway.

Objective Estimating the residual risk of transfusion-transmitted diseases in voluntary blood donors is crucial for monitoring blood safety.and to analyze the evolution trend over a five-year period in Yantai,Shandong Province.Methods This study retrospectively reviewed screening data from Yantai Central Blood Station between 2018 and 2022.We compared the positivity rates between first-time and repeat donors,calculated the prevalence of each virus,and estimated the residual risk using the prevalence-window period model.Meanwhile,the age characteristics of all positive donors were analyzed.Results Over the five-year period,a total of 320 016 individuals donated blood.The overall reaction rate of transfusion-transmitted diseases was 0.165%,with HBV(0.129%)being the most common.The positivity rate among first-time donors[P(FTDs)](0.310%)was significantly higher than that among repeat donors[P(RDs)](0.054%)(χ2=312.783,P<0.05).The serological residual risks for HBV,HCV,and HIV were 1∶188 090,1∶1 042 805,and 1∶392 995,respectively.During the five-year period,they decreased from 1∶129 495 to 1∶390 011,from 1∶697 002 to 1∶1 145 826,and from 1∶684 109 to 1∶1 067 317,respectively.The residual risks of HCV and HIV after NAT were 1∶22 369 329 and 1∶6 639 965,respectively,which were significantly reduced by 21.5-fold and 16.9-fold,and decreased steadily during the study period.Among the HBV-DNA(+)donors,61.8%(68/110)were RDs,and the residual risk was 1∶65 350.Conclusion This study demonstrates the remarkable effectiveness of introducing nucleic acid amplification technology(NAT)in reducing the residual risk of HBV,HCV,and HIV,particularly for HCV and HIV.The residual risk for HBV remains higher compared to HCV and HIV due to the discovery of occult HBV infections(OBI).Therefore,a crucial step toward further reducing this residual risk is the use of more sensitive reagents and detection platforms.Furthermore,implementing effective long-term incentive mechanisms and strategic planning to increase the proportion of repeat donors(RDs)is critical for enhancing transfusion safety.

Objective:To investigate the potential profiles of imposter phenomenon in undergraduate nursing interns, and to analyze inter-group differences and associated influencing factors.Methods:A total of 216 undergraduate student nurses on placement from January 2023 to July 2024 were surveyed using a general information questionnaire, the Imposter Phenomenon Scale, and the Social Support Rating Scale. The data were used to identify latent profiles and influencing factors associated with imposter phenomenon among the student nurses, with the use of Mplus 8.3 and SPSS, respectively.Results:The mean imposter phenomenon score of the nursing students was (57.88±10.38) points. They were divided into three groups: low-, intermediate-, and high-level imposter syndrome groups, accounting for 17.13%, 38.89%, and 43.98%, respectively. Sex (odds ratio [ OR]=10.514, 95% CI: 3.021-36.588), monthly family income ( OR=0.154, 95% CI: 0.051-0.469), undergraduate grades ( OR=4.947, 95% CI: 1.924-12.723), and social support ( OR=0.051, 95% CI: 0.008-0.322) were factors influencing the profiles of imposter phenomenon among the students. Conclusions:The imposter syndrome of the undergraduate nursing interns is generally at an intermediate level. Nursing managers and nursing educators should provide more assistance to the intermediate- and high-level groups, with a more comprehensive social support system and targeted intervention strategies, so as to effectively reduce their imposter phenomenon level.

Objective:To evaluate the preventive effect of an antimicrobial peptide spray on chemoradiotherapy-induced oral mu-cositis in patients with hematologic malignancies.Methods:From December 2021 to July 2023,a total of 191 newly diagnosed pa-tients with hematologic malignancies undergoing concurrent chemoradiotherapy at our hospital were included in the study.Patients were divided into a treatment group(n=124,received antimicrobial peptide spray)and a control group(n=67,received placebo spray).All patients underwent standardized chemoradiotherapy regimens and oral care.Outcomes compared between groups includ-ed the incidence and severity of oral mucositis,ulcer healing time,pain scores,antibiotic usage,inflammatory markers[C-reactive protein(CRP),procalcitonin(PCT)],duration of neutropenia,adverse events,and quality of life.Results:The incidence of oral mucositis in the treatment group was significantly lower than in the control group(12.90％vs.31.34％,P＜0.05),with a relative risk reduction(RRR)of 58.84％,absolute risk reduction(ARR)of 18.44％,and a number needed to treat(NNT)of 5.423.The treatment group showed shorter ulcer healing time,lower pain scores,reduced antibiotic usage and intensity,lower mean levels of CRP and PCT,and a shorter duration of neutropenia.The incidence of exacerbated local pain and drug-related adverse reactions was also significantly lower in the treatment group,compared to the control group(P＜0.05),with no evident systemic toxicity ob-served.Patients in the treatment group reported higher quality of life and satisfaction scores(both P＜0.05).Conclusion:The an-timicrobial peptide spray effectively reduces the incidence and severity of chemoradiotherapy-associated oral mucositis,mitigates in-flammation and infection risk,and improves quality of life.

Objective To establish a rat model of venous thrombosis in a plateau hypobaric hypoxic environment and to investigate the effect of this environment on venous thrombosis.Methods A total of 144 healthy male SD rats were assigned randomly to four groups(n=36 rats per group):a plains sham operation(A)group,plains operation(B)group,plateau altitude 6000 m+sham operation(C)group,and plateau altitude 6000 m+surgery(D)group.Rats in A and B groups were maintained in a plains normoxic environment,while rats in C and D groups C and D were subjected to a plateau environment.Rats in the surgical groups underwent quantitative constriction to incompletely obstruct the inferior vena cava blood flow.Each group was further divided into subgroups based on time:1,3,5,7,14,and 21 d(n=6 rats per group).Regular vascular ultrasound monitoring was conducted,and blood samples were taken for whole blood viscosity testing and the assessment of inflammatory indicators,including endothelin-1(ET-1),interleukin-6(IL-6)and tissue factor(TF).Coagulation function was evaluated through the activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),fibrinogen(FIB)and D-dimer.After the observation period,the experimental animals were sacrificed and the limbs were removed.Thrombus samples were stained with hematoxylin/eosin(HE),and the thrombus wet mass was measured.Results The thrombosis incidence was significantly higher in the plateau D group than in B group,accompanied by a marked increase in blood viscosity and hematocrit(P＜0.01).Additionally,levels of ET-1,IL-6,and TF were significantly elevated(P＜0.05),indicating a coagulation disorder.Conclusions A plateau hypoxic environment model can be successfully simulated by quantitative coarctation of the inferior vena cava,combined with a specialized environmental chamber.The findings of this study suggest that a plateau hypoxic environment promotes venous thrombosis.
