ObjectiveTo investigate whether Shixiaosan can improve neurological function and inhibit ferroptosis in rats with cerebral ischemia-reperfusion injury (CIRI) by regulating the nuclear factor E2-related factor 2 (Nrf2)/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) pathway. MethodsA rat model of CIRI was established using the intraluminal filament method. Briefly, cervical blood vessels were separated, branches of the external carotid artery were ligated, and the common carotid artery and internal carotid artery were clamped. A nylon filament was inserted through the opening of the external carotid artery to the origin of the middle cerebral artery to block blood flow and induce cerebral ischemia. After 60-120 min of ischemia, the filament was withdrawn to restore blood flow, and the external carotid artery incision was ligated. The rats were divided into a CIRI group, a Shixiaosan low-dose (-L) group (intragastric administration of 1.26 g·kg-1 Shixiaosan), a Shixiaosan high-dose (-H) group (intragastric administration of 2.52 g·kg-1 Shixiaosan), a donepezil hydrochloride tablet (DON) group (intragastric administration of 0.45 mg·kg-1 DON), and a Shixiaosan -H + Nrf2 inhibitor (ML385) group (intragastric administration of 2.52 g·kg-1 Shixiaosan combined with intraperitoneal injection of 30 mg·kg-1 ML385). An additional 12 rats underwent cervical artery separation followed by incision suturing and served as the control group. Equal volumes of double-distilled water were administered to the CIRI and control groups. Neurological function impairment was assessed using the modified Garcia JH score. Magnetic resonance imaging was used to determine the cerebral infarct volume ratio. Hematoxylin-eosin (HE) staining and Prussian blue staining were performed to observe neuronal injury and iron accumulation in the ischemic penumbra, respectively. Transmission electron microscopy was used to examine the ultrastructure of neuronal mitochondria in the ischemic penumbra. Commercial kits were used to measure ferrous iron (Fe2+), malondialdehyde (MDA), reduced glutathione (GSH) content, and reactive oxygen species (ROS) activity in the ischemic penumbra. The BODIPY (581/591) C11 fluorescent probe was used to detect intracellular lipid peroxidation levels. Western blot was performed to detect protein expression levels of Nrf2, SLC7A11, GPX4, transferrin receptor 1 (TFRC), ferritin heavy chain (FHC), and ferritin light chain (FLC) in the ischemic penumbra. ResultsCompared with the control group, the CIRI group exhibited neuronal injury in the ischemic penumbra, characterized by reduced neuron numbers, nucleolar shrinkage, and interstitial edema. Marked iron accumulation was observed in the tissue. Neuronal mitochondria showed atrophy and rupture, with reduced mitochondrial cristae and increased membrane density. The cerebral infarct volume ratio, Fe2+ content, MDA content, ROS activity, and lipid peroxidation levels were increased, whereas the modified Garcia JH score, GSH content, and protein expression levels of Nrf2, SLC7A11, GPX4, FHC, and FLC were decreased, and TFRC protein expression was increased (P<0.05). Compared with the CIRI group, the Shixiaosan -L group, Shixiaosan -H group, and DON group showed attenuated neuronal injury in the ischemic penumbra, reduced iron accumulation, alleviated mitochondrial damage, decreased cerebral infarct volume ratio, Fe2+ and MDA contents, ROS activity, and lipid peroxidation levels, as well as increased modified Garcia JH scores, GSH content, and protein expression levels of Nrf2, SLC7A11, GPX4, FHC, and FLC, while TFRC protein expression was decreased (P<0.05). The magnitude of changes in all indicators was greater in the Shixiaosan -H group than in the Shixiaosan -L group (P<0.05). Compared with the Shixiaosan -H group, all measured indicators in the Shixiaosan -H + ML385 group showed opposite trends (P<0.05). ConclusionShixiaosan may inhibit ferroptosis and restore neurological function in rats with CIRI by activating the Nrf2/SLC7A11/GPX4 pathway.

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.
3.Research advances in iron metabolism disorder and intracranial atherosclerotic cerebral infarction
Journal of Apoplexy and Nervous Diseases 2026;43(2):185-192
Intracranial atherosclerosis (ICAS) is an important etiology of ischemic stroke and has a complex pathogenesis. Iron is an essential trace element for maintaining normal physiological functions of the human body, and the regulation of iron homeostasis is of great significance for ensuring proper physiological activities. Studies in recent years have shown that iron metabolism disorder plays a pivotal role in the development and progression of intracranial atherosclerotic cerebral infarction, involving various pathological processes such as inflammatory response, cell death, lipid metabolism, and blood-brain barrier dysfunction. This article systematically elaborates on the mechanisms through which iron overload promotes ICAS, including oxidative stress, inflammatory response, and lipid peroxidation,with a focus on the key role of related molecular mechanisms (including glutathione depletion, inhibition of GPX4 activity, and lipid peroxide accumulation)in intracranial atherosclerotic cerebral infarction, in order to provide new ideas for the prevention and treatment of intracranial atherosclerotic disease.
4.Exploration of ethical governance in human genomics research
Chinese Medical Ethics 2026;39(5):571-579
With the rapid development of human genomics technologies and their clinical applications, relevant ethical issues have induced complex ethical governance challenges. These challenges mainly manifest in the dilemma of reconstructing a new social contract under data open sharing, the moral conflict between the collective nature of group data and individual benefits, the problem of structural inequality under precision medicine, the risk of imbalance between costs and benefits, the dilemma of genetic modification from a eugenic perspective, and the issue of proxy consent and privacy protection. International governance practices indicate that these challenges can be addressed to some extent by improving legislation, issuing initiatives, strengthening the functions of ethics committees and corresponding institutions, and focusing on the ethicality of research projects. However, issues such as legal lag and insufficient binding force of initiatives still exist. Meanwhile, although China’s ethical governance work has made continuous progress in top-level design, international exchanges and theoretical research, specialized legislation and cross-subject collaboration mechanisms still necessitate improvement. A systematic ethical governance framework requires establishing a pre-regulatory system, refining ethical review, and promoting specialized legislation and case approval systems. It is also vital to improve genomic data governance, refine cloud platform management mechanisms, and promote hierarchical governance of the data. Furthermore, it is crucial to clarify the responsibilities of the scientific research community, standardize ethical review, strengthen public communication, and build a moral community with the collaborative cooperation of the government, medical and healthcare institutions and their technical personnel, the public, and research subjects. Through the construction of an ethical governance system for human genomics research, this ensures that genomics technologies benefit humanity without transgressing ethical boundaries, thereby achieving the safety, fairness, and sustainability of their research and application.
5.Research progress on the role and molecular mechanisms of growth hormone in myopia development
International Eye Science 2026;26(7):1234-1238
In recent years, the incidence of myopia has been increasing annually, emerging as a significant public health issue, particularly among adolescents. Recombinant human growth hormone(rhGH), a primary treatment for short stature in children, has raised widespread concern due to its potential to promote myopia progression. Recent studies have revealed that growth hormone(GH)may contribute to the development of myopia by regulating scleral extracellular matrix metabolism and axial length through multiple mechanisms, including downstream signaling pathways[e.g., insulin-like growth factor-1(IGF-1)], cellular signaling pathways(e.g., MMP/TIMP balance and the Wnt/β-catenin pathway), and epigenetic mechanisms(e.g., miR-29a and DNA methylation). Therefore, this article reviews recent research progress on the role of GH in the pathogenesis and progression of myopia, with the aim of providing insights into visual protection and myopia prevention strategies for children receiving GH therapy for short stature.

ObjectiveStudies have shown that nuciferine has anti-cerebral ischemia effect, but the specific mechanism of action has not been elaborated. Based on the transcriptome results, the pharmacological mechanism of nuciferine against cerebral ischemia was analyzed from multiple dimensions including tissue, cell, pathological process, biological process and signaling pathway. MethodsThirty SD rats were randomly divided into the sham group, model group and nuciferine group(40 mg·kg-1) according to weight. Except for the sham group, the model of middle cerebral artery occlusion(MCAO) was established by thread embolization method after 30 min of administration in the other two groups. Twenty-four hours after surgery, transcriptome sequencing was used to detect the gene expression profiles in the cortex penumbra of rat cerebral tissue, and gene ontology(GO) and kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed for differentially expressed genes. The mechanismof nuciferine against cerebral ischemia was analyzed from 5 dimensions of tissue, cell, pathological process, biological process and signaling pathway by the transcriptome-based multi-scale network pharmacology platform(TMNP). ResultsTranscriptome sequencing and gene quantitative analysis showed that 667 genes were significantly reversed by nuciferine. Further enrichment analysis of KEGG and GO suggested that the pathways of nuciferine involved regulating stress response, ion transport, cell proliferation and differentiation, and synaptic function. TMNP research found that at the tissue level, nuciferine could significantly improve the cerebral tissue injury caused by ischemia. At the cellular and pathological levels, nuciferine could play an anti-cerebral ischemia role by improving the state of various nerve cells, mobilizing immune cells, regulating inflammation. And at the level of biological processes and signaling pathways, nuciferine mainly acted on the processes such as vascular remodeling, inflammation-related signaling pathways, and synaptic signaling. ConclusionCombined with the results of transcriptome sequencing, gene quantitative analysis and TMNP, the mechanism of nuciferine against cerebral ischemia may be related to processes such as intervening in stress response and inflammation, affecting vascular remodeling and regulating synaptic function. These results can provide a basis and reference for further study of the pharmacological mechanism of nuciferine against cerebral ischemia.

Objective To analyze the epidemiological characteristics and risk factors of chronic kidney disease in patients with 10 years of hypertension. Methods A total of 350 patients with 10 years or longer course of hypertension who underwent physical examination in the Second Affiliated Hospital of Air Force Medical University from June 2021 to June 2024 were selected. General information of the patients was collected through questionnaires. Renal function related indicators and imaging results were obtained through relevant laboratory tests and imaging examinations. Based on the results of renal function related indicators, the epidemiological characteristics of chronic kidney disease in hypertensive patients with 10 years of hypertension, as well as risk factors for chronic kidney disease in the hypertensive patients were identified. Results Among the 350 patients enrolled in this study, there were 71 (20.29%) with proteinuria, 32 (9.14%) with hematuria, and 40 (11.43%) with decreased renal function. A total of 80 (22.86%) cases with structural variations such as kidney stones and cysts were detected by renal B-mode ultrasound. There were 121 (34.57%) patients with hypertension and chronic kidney disease. There were statistically significant differences in gender, age, diabetes, hyperlipidemia and hyperuricemia between patients with chronic kidney disease and those without (P<0.05). Multivariate logistic regression analysis results showed that gender, age, diabetes, hyperlipidemia, and hyperuricemia were the risk factors for chronic kidney disease in patients with hypertension (P<0.05). Conclusion Patients with 10 years of hypertension have a high risk of chronic kidney disease, and the risk factors include gender, age, diabetes, hyperuricemia, and hyperlipidemia.

ObjectiveTo evaluate the clinical efficacy and safety of Huaban Jiedu Formulation (化斑解毒方, HJF) in treating psoriasis vulgaris with blood-heat syndrome. MethodsA randomized, double-blind, placebo-controlled study was conducted with 60 patients diagnosed with psoriasis vulgaris of blood-heat syndrome. Patients were randomly assigned to either a treatment group or a control group, with 30 cases in each. The treatment group received HJF granules orally, one dose a day, combined with topical Qingshi Zhiyang Ointment (青石止痒软膏), while the control group received placebo granules, one dose a day, combined with the same topical ointment. Both groups were topically treated twice daily of 28 days treatment cours. Psoriasis area and severity index (PASI), visual analogue scale for pruritus (VAS), traditional Chinese medicine (TCM) syndrome scores, dermatology life quality index (DLQI), and psoriasis life stress inventory (PLSI) were assessed before treatment and on day 14 and day 28. Response rates for PASI 50 (≥50% reduction) and PASI 75 (≥75% reduction), as well as overall clinical efficacy, were compared between groups. Serum levels of interleukin-6 (IL-6) and interleukin-17 (IL-17) were measured before and after 28 days of treatment. Adverse reactions during treatment were recorded. ResultsAfter 28 days of treatment, both groups showed significant reductions in PASI total score, lesion area score, erythema, scaling, and infiltration scores, pruritus VAS score, TCM syndrome score, DLQI, PLSI, and serum IL-6 and IL-17 levels (P<0.05). Compared to the control group, the treatment group had significantly greater improvements in PASI total score and erythema score, TCM syndrome score, serum IL-6 and IL-17 levels, and PASI 50 response rate after 28 days (P<0.05). Between-group comparisons of score differences before and after 28-day treatment revealed that the treatment group showed significantly better improvements in PASI total, lesion area score, erythema score, TCM syndrome score, DLQI, PLSI, and inflammatory markers (P<0.05 or P<0.01). The total effective rate on day 14 and day 28 was 40.00% (12/30) and 83.33% (25/30) in the treatment group, versus 6.90% (2/29) and 41.38% (12/29) in the control group, respectively. The clinical efficacy in the treatment group was significantly superior to that in the control group (P<0.05). Mild gastric discomfort occurred in 3 patients in the treatment group and 1 in the control group. ConclusionHJF can effectively improve skin lesions and TCM symptoms relieve pruritus, enhance quality of life, and reduce inflammatory markers IL-6 and IL-17, in patients with blood-heat syndrome of psoriasis vulgaris, with a good safety profile.

ObjectiveTo explore the mechanism by which Zuoguiwan improves the pancreas development in the gestational diabetes mellitus (GDM) model by observing the effects of Zuoguiwan on the expression of key regulatory factors in different stages of pancreas development. MethodsPregnant Wistar rats were randomly assigned into blank, model, insulin detemir (20 U·kg-1) and Zuoguiwan (1.89 g·kg-1) groups (n=18). GDM was induced by peritoneal injection of streptozotocin on day 6.5 (E6.5d) in the embryonic stage, and the blank group was given an equal volume of sodium citrate buffer. The modeling performance was assessed by measuring the blood glucose of pregnant rats. Except the blank group and model group, pregnant rats in other groups were administrated with corresponding drugs from E9.5d to delivery. The random blood glucose of pregnant rats was monitored, and the embryos and offspring rats were measured for the length and weighed on E12.5d, E18.5d and day 21 after birth (B21d). The Lee's index of rats on B21d was calculated. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the fasting insulin (FINS) levels of B22d rats and the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) was calculated. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), total cholesterol (CHO), triglyceride (TG), high-density lipoprotein cholesterol (HDL), and low-density lipoprotein cholesterol (LDL) in E18.5d pregnant rats and B22d offspring were determined. The pathological changes in the pancreas of E12.5d, E18.5d and B22d rats were observed by hematoxylin-eosin (HE) staining. Western blot was used to determine the protein levels of pancreatic duodenal homeobox 1 (Pdx1), pancreas-specific transcription factor 1a (Ptf1a), and sex-determining region Y-box protein 9 (Sox9) in the pancreas of E12.5d embryos, Pdx1, Nkx2 homeobox 2 (Nkx2.2), and hairy and enhancer of split-1 (Hes1) in the pancreas of E18.5d embryos, and Pdx1, v-maf musculoaponeurotic fibrosarcoma oncogene homolog A (Mafa), and NK transcription factor-related homeobox gene family 6 locus 1 (Nkx6.1) in the pancreas of B22d rats. ResultsCompared with the blank group, the model group showed elevated blood glucose levels in pregnant rats on B0d, E9.5d, E12.5d, E15.5d, and E18.5d (P<0.05, P<0.01), decreased body weight and body length (P<0.01) and increased Lee's index in the offspring. In addition, the B22d offspring showed rising levels of FBG, FINS, HOMA-IR, AST, and TG (P<0.01), a declined level of HDL (P<0.01), and pancreatic acinous cells with edema and loose arrangement. The pregnant rats on E18.5d exhibited raised levels of ALT, AST, and TG (P<0.05, P<0.01) in the pancreas and a declined level of HDL (P<0.05). The E12.5d embryos showed up-regulated protein levels of Pdx1, Sox9, and Ptf1a in the pancreas (P<0.01) and the E18.5d embryos exhibited down-regulated protein levels of Pdx1, Nkx2.2, and Hes1 in the pancreas (P<0.01). The protein levels of Pdx1, Nkx6.1, and Mafa in the pancreas of B22d offspring were down-regulated (P<0.01). Compared with the model group, the insulin group exhibited lowered blood glucose in pregnant rats on B0d, E15.5d, and E18.5d (P<0.05, P<0.01). The offspring in all treatment groups showcased increased body weight and body length (P<0.01) and decreased Lee's index. The B22d offspring exhibited declined levels of FBG, FINS, and HOMA-IR in the insulin group (P<0.01) and lowered levels of FBG and HOMA-IR in the Zuoguiwan group (P<0.01). The B22d offspring in all the treatment groups showed reduced levels of ALT, AST, TBIL, CHO, TG, and LDL, a raised level of HDL, and alleviated edema of pancreatic acinous cells. The pregnant rats on E18.5d demonstrated declined levels of TG and ALT (P<0.05, P<0.01) and an elevated level of HDL (P<0.05). The pancreas of E12.5d embryos presented down-regulated protein levels of Pdx1 and Sox9 and an up-regulated protein level of Ptf1a in the insulin group (P<0.05). The pancreas of E12.5d embryos in the Zuoguiwan group presented down-regulated protein levels of Pdx1, Sox9, and Ptf1a (P<0.01). All the treatment groups showed up-regulated protein levels of Pdx1, Nkx2.2, and Hes1 in the pancreas of E18.5d embryos (P<0.01) and Pdx1, Nkx6.1, and Mafa in the pancreas of B22d embryos (P<0.05, P<0.01). ConclusionZuoguiwan can promote the growth and development and ameliorate the pathological changes in the pancreas of the offspring of GDM model by regulating the expression of Pdx1 pathway-related regulatory factors in different stages of pancreas development.
