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: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.
