OBJECTIVE To provide references for the accurate identification and management of immune-related cutaneous adverse events (irCAEs) caused by durvalumab, and ensuring safe clinical drug use. METHODS Clinical pharmacists participated in the diagnosis and treatment process of a patient with gallbladder cancer who developed irCAEs caused by durvalumab. The clinical pharmacists systematically reviewed the patient’s past medical history and medication history, and assisted physicians in assessing the association between adverse drug reactions and administered drugs. Meanwhile, the clinical pharmacists conducted a graded assessment of the adverse reaction, proposed recommendations such as discontinuing durvalumab and adjusting the administration regimen of glucocorticoids, assisted physicians in restarting immunotherapy, and carried out medication education and other pharmaceutical care. RESULTS The occurrence of irCAEs in this patient was “highly likely” related to durvalumab and was classified as severe. The physicians adopted the clinical pharmacist’s opinion, and after symptomatic treatment, the patient’s skin symptoms improved, and discharged with medication. After the completion of glucocorticoid therapy for the patient, the physician restarted immunotherapy with tislelizumab, and no related adverse reactions occurred again in the patient. CONCLUSIONS Durvalumab can cause irCAEs such as severe skin maculopapular rash. In clinical practice, it is crucial to promptly identify and discontinue suspicious drugs, immediately implement effective symptomatic treatment measures, and actively resume immunotherapy to ensure the continuity and safety of the patient’s treatment.

OBJECTIVE To investigate the potential mechanism by which Juanxiao decoction improves bronchial asthma (hereinafter referred to as “asthma”) based on the nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3) inflammasome signaling pathway. METHODS Female SD rats were randomly assigned to normal group, model group and Juanxiao decoction low-, medium- and high-dose groups (0.36, 0.72 and 1.44 g/kg, calculated based on crude drug weight), as well as positive control group (Dexamethasone acetate tablets, 0.2 mg/kg), with 10 rats in each group. Except for the normal group, asthma models were established in the remaining groups via intraperitoneal injection of ovalbumin combined with aluminum hydroxide, followed by nebulized inhalation of ovalbumin. On day 14 of the experiment, rats in each group received intragastric administration of the corresponding solution or normal saline, once a day, for 7 consecutive days. Following the final administration, the following parameters were measured in each group: lung function indexes (forced vital capacity, forced expiratory volume in 0.3 second, peak expiratory flow), serum levels of inflammatory markers (interleukin-1β, interleukin- 18), and the percentages of inflammatory cells (lymphocytes, eosinophils, neutrophils) in bronchoalveolar lavage fluid. Histopathological changes in lung tissue were observed, and the protein and mRNA expressions of nuclear factor-kappa B (NF- κB), NLRP3 and caspase-1 in lung tissue were detected. RESULTS Compared with the normal group, pathological changes such as alveolar wall thickening and inflammatory cell infiltration were observed in rats in the model group. All pulmonary function indicators were significantly reduced in rats in the model group and the administration groups. The levels of inflammatory markers, the percentages of inflammatory cells, and the protein and mRNA expressions of NF-κB, NLRP3 and caspase-1 were significantly elevated or up-regulated (P<0.05). Compared with the model group, pathological changes in rats in each dosage group of Juanxiao decoction were significantly alleviated, and all quantitative indicators showed dose-dependent improvements (P<0.05). CONCLUSIONS Juanxiao decoction can reduce airway inflammatory responses in asthmatic rats, alleviate lung function impairment, and improve pathological changes such as inflammatory cell infiltration. Those effects may be related to the inhibition of the NLRP3 inflammasome signaling pathway.

ObjectiveTo investigate the material basis of the pathogenesis of cerebral ischemic injury with blood stasis and toxin syndrome and to explore the protective effects of Huayu Jiedu prescription (HYJDP) on neutrophil extracellular trap-related cell death (NETosis) in cerebral ischemic injury following acute cerebral infarction. MethodsSeventy-two Sprague-Dawley (SD) rats were randomly divided into six groups (n=12 per group): sham operation (Sham) group, blood stasis and toxin model (Model) group, low-, medium-, and high-dose HYJDP groups (HYJDP-L, HYJDP-M, and HYJDP-H; 9, 18, and 36 g·kg-1, respectively), and butylphthalide (NBP) group (0.06 g·kg-1). Except for the Sham group, rats in all other groups were subjected to carrageenan/dry yeast combined with a modified intraluminal filament method to establish a focal cerebral ischemia model of the middle cerebral artery with blood stasis and toxin syndrome. Neurological function was evaluated at 24 h after modeling using the Zea-Longa neurological deficit score. Cerebral infarction rate was assessed by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Pathological morphology of brain tissue was observed using hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay (ELISA) was used to determine serum levels of interleukin-8 (IL-8), myeloperoxidase-DNA complexes (MPO-DNA), and citrullinated histone H3 (CitH3). Protein expression of phosphorylated phosphatidylinositol 3-kinase (p-PI3K), protein kinase B (p-Akt), mammalian target of rapamycin (p-mTOR), sequestosome 1 (p62), and CitH3 in brain tissue was detected by Western blot. Immunofluorescence (IF) was used to detect the expression of neutrophil-specific marker Ly6G, CitH3, and neuron-specific nuclear protein (NeuN) in brain tissue. ResultsCompared with the Sham group, neurological deficit scores and cerebral infarction rates in the model group were significantly increased (P<0.01 for both). HE staining showed varying degrees of neuronal degeneration and necrosis, characterized by blurred neuronal structures, nuclear pyknosis and fragmentation, cytoplasmic dissolution into a vacuolated reticular pattern, and mild glial cell proliferation. ELISA results showed that serum levels of IL-8, MPO-DNA, and CitH3 were significantly increased (P<0.01). Western blot analysis demonstrated decreased expression of p-PI3K, p-Akt, p-mTOR, and p62, while CitH3 expression was significantly increased (P<0.01). IF results showed an increased number of NETs+ cells and a significant decrease in NeuN+ cells (P<0.01). Compared with the Model group, neurological deficit scores in the HYJDP-H group were significantly decreased (P<0.05), and cerebral infarction rates in the HYJDP-H and NBP groups were significantly reduced (P<0.01). HE staining showed that brain tissue damage was markedly alleviated in the HYJDP-H group. ELISA results showed that levels of IL-8, MPO-DNA, and CitH3 were significantly decreased in the HYJDP-M, HYJDP-H, and NBP groups (P<0.01). Western blot analysis showed that expression of p-PI3K, p-Akt, p-mTOR, and p62 was significantly increased in the HYJDP-H and NBP groups, while CitH3 expression was significantly reduced in all drug intervention groups (P<0.01). IF results showed that the number of NETs+ cells was significantly decreased and the number of NeuN⁺ cells was significantly increased in all drug intervention groups (P<0.01). ConclusionNETs may be the material basis of the pathogenesis of cerebral ischemic injury characterized by blood stasis and toxin. HYJDP can regulate the PI3K/Akt/mTOR signaling pathway, reduce the release of pro-inflammatory mediators and NETosis-related products, alleviate cerebral ischemic injury caused by autophagy-dependent NETosis, and thereby exert a neuroprotective effect.

ObjectiveTo investigate the effect and mechanism of simvastatin pretreatment on kidney ischemia reperfusion injury (IRI) in mice. MethodsFifteen male C57BL/6 mice aged 6-8 weeks were divided into three groups: Sham operation group (Sham group), kidney IRI group (IR group), and simvastatin pretreatment+kidney IRI group (SIM group). Hematoxylin-eosin (HE) staining of kidney tissue and detection of serum creatinine (SCr) and lactate dehydrogenase (LDH) were used to evaluate kidney injury. The levels of superoxide dismutase (SOD), reduced glutathione (GSH), malondialdehyde (MDA) and reactive oxygen species (ROS) were detected to evaluate oxidative stress. The contents of ferrous iron (Fe2+) and ferric iron (Fe3+) in kidney tissue were detected, and the morphological changes of mitochondria were observed by transmission electron microscope. The relative expression levels of Kruppel-like factor 2 (KLF2), glutathione peroxidase 4 (GPX4), solute carrier family 7 member 11 (SLC7A11), and acyl-coa synthetase long chain family member 4 (ACSL4) protein in kidney tissue were detected. ResultsCompared with the IR group, the SIM group had significantly reduced renal tubular injury and decreased contents of Scr and LDH in serum (P < 0.001). It also showed increased expression of SOD and GSH and decreased expression of MDA and ROS (P < 0.01). Simvastatin pretreatment reduced the contents of Fe2+ and Fe3+ in the tissues (P < 0.01) and alleviated mitochondrial damage. It also promoted the expression of KLF2 (P < 0.01), up-regulated the expression of ferroptosis-related protective proteins GPX4 and SLC7A11, and down-regulated the expression of ferroptosis-related damage protein ACSL4 (P < 0.05). ConclusionSimvastatin pretreatment may inhibit kidney ferroptosis by promoting the expression of KLF2 to alleviate kidney IRI.

Abnormal activation of the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway is involved in the pathogenesis of diffuse large B-cell lymphoma (DLBCL). In recent years, inhibitors targeting JAK2 and STAT3 have emerged as promising therapeutic candidates in DLBCL. This review summarizes the efficacy and safety profiles of JAK2 inhibitors (e.g., ruxolitinib) and STAT3 inhibitors (direct small-molecule inhibitors, the antisense oligonucleotide, and proteolysis targeting chimeras, etc.) in preclinical models and clinical trials. Accumulating evidence indicates that JAK2 and STAT3 inhibitors exhibit antitumor activity and are generally well tolerated in a subset of DLBCL patients. Meanwhile, the development of novel drug delivery systems has significantly enhanced the stability, bioavailability, and targeting ability of the compounds. Furthermore, JAK2 and STAT3 inhibitors may exhibit synergistic effects when combined with other therapy strategies (such as combinations with B-cell receptor signaling pathway inhibitors, immunomodulators, or other targeted drugs). However, current clinical applications are still in their early stages. Future research should concentrate on precision treatment strategies based on the genetic subtyping of DLBCL, and further refine the delivery systems for inhibitors as well as combination drug regimens to improve clinical outcomes.

The theory of constitution in traditional Chinese medicine (TCM) has emerged as a new discipline in recent years. Constitution plays a vital role in the onset,progression,transformation,and prognosis of diseases. At present,some clinical scholars have adopted a novel diagnostic and treatment model of "constitution differentiation-disease identification-syndrome differentiation",in which constitution is regarded as a core element throughout the diagnostic and therapeutic process. Constitution is closely associated with etiology,onset,pathogenesis,syndrome differentiation,and treatment. Against this background,the construction of animal models based on constitution holds far-reaching significance for advancing clinical research. This paper focuses on the construction and evaluation of rodent models with Qi-deficiency constitution,aiming to explore how to further induce Qi-deficiency syndromes and related disease states on the basis of Qi-deficiency constitution models,thereby developing an integrated animal model that embodies the trinity of "constitution-disease-syndrome". The establishment of this model not only provides a solid experimental foundation for the development of new therapies and drugs in TCM targeting specific constitutions,diseases,and syndromes,but also greatly promotes the modernization and scientific advancement of TCM theory. By comprehensively applying multidisciplinary technologies and methods,the study evaluates the model's validity,reliability,and practicality,with the aim of opening new avenues for future research in TCM and promoting the development of the field.

Objective To systematically analyze the characteristics of the disease burden of hypertensive heart disease (HHD) in the elderly (≥60 years) globally and in China from 1990 to 2021, and to predict its future trends from 2022 to 2040, with the aim of providing data support for optimizing comprehensive prevention and control strategies for HHD. Methods Based on the Global Burden of Disease (GBD) 2021 database, the number of prevalent cases and disability-adjusted life years (DALYs) of HHD in the elderly were extracted for the world, China, and five regions categorized by sociodemographic index (SDI). Joinpoint regression was used to analyze the temporal trends of age-standardized prevalence rate and age-standardized DALYs rate of HHD in the elderly. A three-factor decomposition method was applied to evaluate the relative contributions of aging, population growth, and epidemiological changes to the variations in the elderly HHD burden. Additionally, a Bayesian age-period-cohort model was used to predict the elderly HHD burden from 2022 to 2040. Results In 2021, the number of prevalent elderly HHD cases reached 10 283 000 globally and 3 412 400 in China, representing increases of 179.20% and 159.20% respectively, compared with 1990. The DALYs of elderly HHD were 18 812 700 person-years globally and 4 731 400 person-years in China, rising by 76.08% and 29.45% respectively from 1990. Meanwhile, the growth rates of the number of prevalent cases and DALYs of elderly HHD varied across different SDI regions. From 1990 to 2021, the age-standardized prevalence rate of elderly HHD in China, as well as the age-standardized DALYs rate of elderly HHD both globally and in China, showed significant downward trends (all average annual percentage changes<0, all P<0.001). In 2021, the 70-74 years age group accounted for the highest proportion of prevalent cases and DALYs of elderly HHD, both globally and in China. Decomposition analysis revealed that population growth was the dominant factor driving the increase in the elderly HHD burden across all regions. The prediction model results indicated that the number of prevalent cases and DALYs of elderly HHD would continue to rise globally and in China from 2022 to 2040, with the growth rate of the elderly HHD burden in China between 2021 and 2040 expected to exceed the global average. Conclusion Over the past 32 years, although the age-standardized disease rates of elderly HHD have mainly shown a downward trend globally and in China, the absolute number of the disease burden has increased substantially. The projection model indicates a continued upward trajectory, with the growth rate in China higher than the global average. Therefore, there is an urgent need to implement precise prevention and control strategies to effectively mitigate the disease burden of elderly HHD.

ObjectiveTo explore the possible action mechanism of Qingshi Anti-itch Ointment (青石止痒软膏, QAO) in the treatment of psoriasis. MethodsForty mice were randomly divided into four groups, blank group, model group, calcipotriol group and QAO group, with 10 mice in each group. Except for the blank group, psoriasis was induced by applying imiquimod cream to the dorsal skin. After modeling for 6 hours daily, the calcipotriol group and QAO group were treated with 0.5 g of calcipotriol ointment or 0.5 g of QAO, respectively, applied to the treated dorsal skin. The blank group and the model group received no treatment. The skin lesions were observed, and the psoriasis area and severity index (PASI) score was assessed every other day. After 7 days, Hematoxylin and Eosin (HE) staining was performed on dorsal skin tissue to observe pathological changes. The levels of interleukin 1β (IL-1β) and interleukin 18 (IL-18) were determined by enzym-linked immunosorbent assay (ELISA). The protein levels of Caspase-1,Pro-Caspase-1, gasdermin D (GSDMD) and gasdermin-D-N (GSDMD-N) were detected by Western Blot (WB). The protein levels of GSDMD were observed by immunohistochemistry. ResultsCompared with the blank group, the model group mice showed redness, erythema, and white scales on their skin, with histological observations indicating epidermal thickening, elongated spines, and infiltration of inflammatory cells. The PASI scores of the skin tissue on days 1, 3, 5, and 7 were elevated; the IOD and AOD values of GSDMD protein increased; the protein levels of Caspase-1, Pro-Caspase-1,GSDMD, GSDMD-N, and IL-1β and IL-18 were significantly elevated (P<0.05 or P<0.01). Compared with the model group, the QAO group and calcipotriol group showed lighter skin lesions; the PASI scores on day 5 and day 7 in the QAO group, and on day 3, 5, and 7 in the calcipotriol group, were reduced; the IOD and AOD values of GSDMD protein, and the protein level of Caspase-1, GSDMD, and GSDMD-N, as well as level of IL-18 and IL-1β decreased in both groups; in the calcipotriol group, Pro-Caspase-1 protein level also decreased (P<0.05 or P<0.01). Compared with the calcipotriol group, the QAO group showed slightly redder skin, more obvious thickening of the stratum corneum, and less capillary dilation; the PASI scores on day 3 and day 7 increased, while the score on day 5 was reduced; the protein level of Pro-Caspase-1, GSDMD, GSDMD-N, and the level of IL-18 and IL-1β were increased in the QAO group (P<0.05). ConclusionQAO can effectively relieve psoriasis dermatitis in mice. Its potential mechanism may be related to the regulation of the Caspase-1/GSDMD protein pathway, down-regulation of IL-18 and IL-1β levels, and alleviation of pyroptosis.
