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 effects of prostaglandin E₂ （PGE₂） microinjection into the median preoptic nucleus （MnPO） on core body temperature in female mice， and to clarify its underlying mechanism. MethodsMicroinjection cannula were implanted into the MnPO of female mice using stereotaxic surgery.Subsequently， a multi-channel temperature acquisition system was used to simultaneously monitor rectal and brown adipose tissue （BAT） temperatures before and after intra-MnPO injections of different reagents.To investigate the thermoregulatory effects of the microinjection of PGE₂ into the MnPO， 12 female C57BL/6 mice were randomly divided into a saline group （n=6） and a PGE₂ group （n=6）， which were injected with 0.1 μL saline and PGE₂ （2.8 mmol/L）， respectively.To determine whether E-series prostaglandin receptor （EP）1， EP3， and EP4 receptors mediate the thermoregulatory effects of PGE₂， 15 female C57BL/6 mice were randomly divided into 3 groups （n=5 per group）.Mice in each group first received an injection of 0.1 μL PGE2 （2.8 mmol/L） into the MnPO. After their body temperature returned to baseline levels， they were subsequently injected with a mixture of either EP1， EP3 or EP4 antagonist （ant） （20 mmol/L） + PGE2 （2.8 mmol/L）. ResultsCompared with baseline level， the rectal temperature （P<0.01） and BAT temperature （P<0.001） of female mice both increased significantly after microinjection of PGE₂ into the MnPO.Compared with the saline group， the increases in rectal temperature （P<0.001） and BAT temperature （P<0.000 1） were significantly greater in the PGE₂ group of mice.Furthermore， following the injection of PGE₂ into MnPO， the increase in BAT temperature was found to be significantly greater than that in rectal temperature in mice （P<0.001）.Compared to the administration of PGE₂ alone， co-injection of an EP3 ant + PGE₂ into the MnPO of mice resulted in a significantly smaller increase in both rectal temperature （P<0.001） and BAT temperature （P<0.001）.In contrast， the increases in rectal and BAT temperatures following MnPO injection of either EP1 ant + PGE₂ or EP4 ant + PGE₂ were not statistically significant （P>0.05）. ConclusionInjection of PGE₂ into the MnPO elevates BAT and core body temperature in female mice via the EP3 receptor.

Lung cancer （LC） is a significant global public health issue， with both its incidence and mortality rates ranking among the highest worldwide. The age-standardized incidence and mortality rates are increasing annually， posing a serious threat to the life and health of LC patients. Radical surgical resection is the primary treatment for malignant lung tumors. However， postoperative multidimensional functional impairments， including respiratory， mucosal， and psychological functions， are common. These impairments not only reduce patients' quality of life and affect their treatment tolerance and duration， but also negatively correlate with prognosis， facilitating disease recurrence and metastasis. At present， postoperative functional dysfunction after LC surgery remains a key clinical challenge that urgently needs to be addressed. There is a lack of standardized and regulated postoperative rehabilitation treatment management and traditional Chinese medicine （TCM） differentiation and treatment strategies for LC. Focusing on the core underlying pathogenesis of "Qi sinking" after LC surgery， and guided by the classical TCM theory of "lungs governing Qi"， this study， based on the core concept of the "five perspectives on treatment" theory， innovatively proposes the respiratory dysfunction as the core pathogenesis of "Qi sinking in the chest" during the rapid rehabilitation phase， mucosal dysfunction as the core pathogenesis of "Yin deficiency and Qi sinking" during the postoperative adjuvant treatment phase， and the psychological dysfunction as the core pathogenesis of "Qi sinking with emotional constraint" during the consolidation phase. Accordingly， stage-specific dynamic functional protection strategies are constructed. In the rapid rehabilitation phase， the strategy emphasizes tonifying Qi and uplifting sinking Qi， with differentiation and treatment based on the principle of ''descending before ascending''. In the adjuvant treatment phase， the approach focuses on nourishing Yin and uplifting Qi， with prescription combinations that integrate unblocking and tonification. In the consolidation phase， the strategy aims to resolve constraint and uplift Qi， with clinical treatment emphasizing a combination of dynamic and static methods. At each stage of functional rehabilitation， clinical differentiation and treatment should support healthy Qi and eliminate pathogenic factors simultaneously. This study is the first to propose the concept of postoperative functional protection in TCM， offering a new approach for TCM differentiation and treatment in the full-cycle， stage-based， and dynamic protection of postoperative function in LC patients. It is expected to contribute to the construction and development of an integrated TCM-Western medicine comprehensive program for cancer prevention and treatment in China.

OBJECTIVES: To investigate the structural changes of rat thoracic aorta and changes in expression levels of Bmal1 and cyclins in thoracic aorta endothelial cells following heat stress. METHODS: Twenty male SD rats were randomized equally into control group and heat stress group. After exposure to 32 ℃ for 2 weeks in the latter group, the rats were examined for histopathological changes and Bmal1 expression in the thoracic aorta using HE staining and immunohistochemistry. In the cell experiments, cultured rat thoracic aortic endothelial cells (RTAECs) were incubated at 40 ℃ for 12 h with or without prior transfection with a Bmal1-specific small interfering RNA (si-Bmal1) or a negative sequence. In both rat thoracic aorta and RTAECs, the expressions of Bmal1, the cell cycle proteins CDK1, CDK4, CDK6, and cyclin B1, and apoptosis-related proteins Bax and Bcl-2 were detected using Western blotting. TUNEL staining was used to detect cell apoptosis in rat thoracic aorta, and the changes in cell cycle distribution and apoptosis in RTAECs were analyzed with flow cytometry. RESULTS: Compared with the control rats, the rats exposed to heat stress showed significantly increased blood pressures and lowered heart rate with elastic fiber disruption and increased expressions of Bmal1, cyclin B1 and CDK1 in the thoracic aorta (P<0.05). In cultured RTAECs, heat stress caused significant increase of Bmal1, cyclin B1 and CDK1 protein expression levels, which were obviously lowered in cells with prior si-Bmal1 transfection. Bmal1 knockdown also inhibited heat stress-induced increase of apoptosis in RTAECs as evidenced by decreased expression of Bax and increased expression of Bcl-2. CONCLUSIONS Heat stress upregulates Bmal1 expression and causes alterations in expressions of cyclins to trigger apoptosis of rat thoracic aorta endothelial cells, which can be partly alleviated by suppressing Bmal1 expression.

Gene regulation relies on the precise binding of transcription factors (TFs) at regulatory elements, but simultaneously detecting hundreds of TFs on chromatin is challenging. We developed cFOOT-seq, a cytosine deaminase-based TF footprinting assay, for high-resolution, quantitative genome-wide assessment of TF binding in both open and closed chromatin regions, even with small cell numbers. By utilizing the dsDNA deaminase SsdAtox, cFOOT-seq converts accessible cytosines to uracil while preserving genomic integrity, making it compatible with techniques like ATAC-seq for sensitive and cost-effective detection of TF occupancy at the single-molecule and single-cell level. Our approach enables the delineation of TF footprints, quantification of occupancy, and examination of chromatin influences on TF binding. Notably, cFOOT-seq, combined with FootTrack analysis, enables de novo prediction of TF binding sites and tracking of TF occupancy dynamics. We demonstrate its application in capturing cell type-specific TFs, analyzing TF dynamics during reprogramming, and revealing TF dependencies on chromatin remodelers. Overall, cFOOT-seq represents a robust approach for investigating the genome-wide dynamics of TF occupancy and elucidating the cis-regulatory architecture underlying gene regulation.

Objective:To discuss the effect of prostaglandin E2(PGE2),a pyrogenic mediator,on the discharge activity of warm-sensitive neurons(WSNs)in median preoptic nucleus(MnPO)of hypothalamus in the female mice,and to clarify its mechanism.Methods:Coronal brain slices of MnPO were prepared from the female mice.The slices were then perfused with artificial cerebrospinal fluid(ACSF)containing synaptic transmission blockers(STBs).The discharge frequency was monitored using the patch clamp technique while changing the temperature of the perfusate to identify the WSNs.A total of 32 MnPO WSNs were divided into base line group(n=32)and PEG2(n=32).The patch clamp technique was employed to monitor the discharge frequencies of MnPO WSNs following the perfusion of ACSF and 1 μmol·L-1 PGE2,respectively.The MnPO WSNs with good activity and significant change in discharge frequency after PGE2 perfusion were divided into PGE2 receptor E-series prostaglandin receptrol(EP)1 antagonist(EP1 ant)+PGE2 group(n=7),EP3 ant+PGE2 group(n=7),and EP4 ant+PGE2 group(n=7).The patch clamp technique was used to monitor the discharge frequencies of MnPO WSNs following the perfusion of 3 μmol·L-1 EP1 ant and 1 μmol·L-1 PGE2 mixture,10 μmol·L-1 EP3 ant and 1 μmol·L-1 PGE2mixture,and 10 μmol·L-1 EP4 ant and 1 μmol·L-1 PGE2 mixture,respectively.Resluts:After perfuson of the ACSF containing STBs,a total of 188 MnPO neurons from the female mice with an intrinsic temperature sensitivity coefficient(m value)were identified;out of these,32 neurons had an m value of ≥0.8 and were identified as MnPO WSNs,accounting for approximately 17％of all recorded neurons.Compared with baseline discharge frequency,the discharge frequency of MnPO WSNs after addition of PGE2 was decreased(P＜0.05).Compared with PGE2 group,the percentage change in discharge frequency of MnPO WSNs in EP3 ant+PGE2 group was significantly decreased(P＜0.05).Compared with PGE2 group,the percentage change in discharge frequency of MnPO WSNs in EP1 ant+PGE2 group had no significant difference(P＞0.05).Compared with PGE2 group,the percentage change in discharge frequency of MnPO WSNs in EP4 ant+PGE2 group had no significant difference(P＞0.05).Conclusion:In the female mice,WSNs make up approximately 17％of the total neurons in MnPO.PGE2 can directly inhibit the discharge activity of MnPO WSNs in the female mice through postsynaptic mechanism involving EP3 receptors.

Objective To assess the intervention effect of nicotinamide mononucleotide (NMN) on the mouse model of hematotoxicity induced by subacute benzene exposure. Methods Benzene exposure and NMN intervention were adopted in a 2×2 factorial design, as benzene exposure and non-exposure, and NMN intervention and non-intervention. Male specific pathogen-free C57BL/6J mice were randomly assigned to negative control group, NMN control group, simple benzene exposure group and NMN intervention group, with 12 mice in each group. Benzene exposure of mice in simple benzene exposure group and NMN intervention group was conducted by dynamic inhalation of benzene at a concentration of 325 mg/m³ for six hours per day, five days per week for four weeks (28 days). Mice in the negative control and NMN control group inhaled clean air. During benzene exposure, mice in the NMN control group and NMN intervention group received NMN in drinking water at a dose of 300 mg/kg body weight. Peripheral blood samples of mice were collected for complete blood count analysis and calculation of composite inflammatory indices after 28 days. Results Interaction analysis showed that the counts of peripheral white blood cell, neutrophil, lymphocyte, and platelet of mice in the simple benzene exposure group were lower than those in the negative control group (all P<0.05). Neutrophil and platelet counts in the NMN intervention group were higher than those in the simple benzene exposure group (all P<0.05). The results of main effect analysis showed that the monocyte count of peripheral blood, systemic inflammatory index, systemic inflammatory response index, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio of mice in the benzene exposure group increased (all P<0.05), and the basophil count and lymphocyte/monocyte ratio decreased (all P<0.05), compared with the control group. Conclusion Oral NMN alleviates subacute benzene-induced decreases in peripheral neutrophil and platelet counts in mice. This protective effect may be related to the targeted intervention of NMN on mitochondrial energy metabolism disorder and oxidative damage induced by benzene exposure in male mice.

Objective To develop a predictive model for guiding blood transfusion decisions in pediatric patients with traumatic brain injury(TBI)by identifying and analyzing key factors that influence blood transfusion requirements.Methods A retrospective analysis was conducted on the clinical data of 1,535 pediatric patients with TBI admitted to four medical institutions from January 1,2015,to December 31,2022.Patients were divided into two groups:those who received red blood cell transfusions during hospitalization and those who did not.Comparative analyses were performed on demographic,clinical,and laboratory data between these two groups.Logistic regression analysis was used to identify risk factors associated with in-hospital blood transfusion,and a predictive model was developed using a nomogram.The performance of this model was evaluated using a receiver operating characteristic(ROC)curve.Results Significant differences were observed between the blood transfusion and non-blood transfusion groups in terms of baseline demographics,clinical indicators,and laboratory test results(all P<0.05).Patients in the blood transfusion group exhibited significantly higher in-hospital mortality,compli-cation rates,use of mechanical ventilation,ICU admission rates,and length of stay compared to those in the non-blood transfusion group(all P<0.05).Multivariate logistic regression analysis identified heart rate,presence of other fractures,treatment methods,hemoglobin(Hb),platelet count(Plt),activated partial thromboplastin time(APTT),and D-dimer levels as independent risk factors for blood transfusion in TBI patients.The area under the ROC curve for the blood transfusion prediction model,based on these independent risk factors,was 0.95(95%CI:0.94～0.97),indicating excellent predictive accuracy.Calibration and decision curves further validated the robust-ness and reliability of the model's predictive capacity.Conclusions Heart rate,presence of other fractures,treatment methods,Hb,Plt count,APTT,and D-dimer levels serve as independent risk factors for blood transfusion in TBI patients.The prediction model developed based on these factors demonstrates excellent predictive performance,thereby guiding clinicians in making informed blood transfusion decisions and enhancing the success rate of patient outcomes.

Iron,a vital trace element and redox-active metal in the human body,is pivotal in cellular processes and en-gages in a multitude of biological reactions.Ferroptosis,an emerging form of regulated cell death,is predominantly instiga-ted by the excessive free iron that catalyzes reactive oxygen species(ROS)production via the Fenton reaction.This process results in the peroxidation of polyunsaturated fatty acids within the cellular lipid membrane,compromising the membrane's integrity and thereby inducing ferroptosis.In the context of diabetic retinopathy(DR),ferroptosis plays a sig-nificant role.The disruption of iron metabolism,the excessive accumulation of ROS,and the imbalance of the antioxidant system are key mechanisms contributing to ferroptosis in retinal tissues and the exacerbation of DR's pathological progres-sion.This review provides a systematic summary and in-depth discussion of the advancements in understanding the role of ferroptosis in DR pathogenesis,intending to offer valuable insights for future research endeavors in this field.
