OBJECTIVE To explore an intelligent shelf management scheme aimed at enhancing the effective utilization rate of shelves and reducing the risk of dispensing errors for easily confused medicine， thereby facilitating the upgrade of intelligent shelf management in inpatient pharmacies. METHODS An intelligent positioning software based on the “five-level positioning” concept was designed using informational technology. Human-machine collaboration mode was adopted to optimize the shelf management process by integrating priority information， including pharmacological action， drug dosage， packaging color， injection drug type， and label style. Then， the effectiveness of the intelligent positioning software was evaluated comprehensively from multiple aspects such as shelf location arrangement effect， internal dispensing error rate and work experience. RESULTS Compared with the application of intelligent shelf management scheme （April-May， 2025）， the proportion of injectable drugs on the middle layer increased from 59.9% to 78.2% after the application of scheme （June-July， 2025）； the average internal dispensing error rate dropped from 0.098% to 0.049%. Intelligent positioning software ensured precise warehousing positioning， simplified management， reduced dispensing errors and achieved a good experience for pharmacists. In addition， the “intelligent positioning software for pharmaceutical shelf management”， developed based on the “five-level positioning” concept， had been granted one national computer software copyright. CONCLUSIONS In summary， the intelligent positioning software fully considers the actual work needs such as shelf capacity， drug dosage and distance between similar drugs. It can provide accurate prediction of pharmaceutical shelf and optimization scheme， basically achieving dual optimization of low error rate and high dispensing efficiency.

ObjectiveTo investigate the effects of Trpc6 knockout on chronic lipopolysaccharide （LPS）-induced myocardial inflammation and fibrosis in mice and its potential mechanisms. MethodsMale C57BL/6 wild-type （WT） mice and Trpc6 knockout （Trpc6^-/-） mice of the same background were randomly divided into four groups： WT control， WT+LPS （200 μg/kg）， Trpc6^-/- control， and Trpc6^-/-+LPS （200 μg/kg）. Group with LPS received intraperitoneal LPS injections for 21 consecutive days to induce chronic myocardial inflammatory injury. Cardiac ultrasound assessed changes in left ventricular ejection fraction （EF）， left ventricular shortening fraction （FS）， and cardiac output （CO）. Hematoxylin and eosin （HE） staining and periodic acid-Schiff （PAS） staining were used to examine morphological alterations in myocardial tissue. Masson’s trichrome staining was used to assess myocardial fiber alterations； Western blot analysis was used to measure myocardial tissue expression of transient receptor potential calcium channel 6 （TRPC6）， NOD-like receptor family pyrin domain-containing 3 inflammasome （NLRP3），absent in melanoma 2 inflammasome （AIM2）， Caspase-1， interleukin （IL）-6， and IL-1β in mouse myocardial tissue. ResultsCompared with the WT control group， the WT+LPS group exhibited decreased cardiac EF （P<0.01）， FS （P<0.01）， and CO （P<0.05）， along with significantly increased myocardial tissue damage， glycoprotein deposition， and fibrosis （P<0.01）. Further analysis revealed that compared with the WT control group， the WT+LPS group exhibited markedly increased myocardial tissue expression of TRPC6， NLRP3， AIM2， Caspase-1， IL-6， and IL-1β （P<0.01）. Compared with the WT+LPS group， mice in the Trpc6^-/- +LPS group exhibited elevated EF （P<0.01） and FS （P<0.05）， along with reduced myocardial tissue injury， glycoprotein deposition， and fibrosis （P<0.05）. ConclusionChronic LPS treatment can activate NLRP3/AIM2 inflammasomes through the up-regulation of TRPC6 expression， and then lead to chronic myocardial inflammatory injury and fibrosis， while Trpc6 knockdown can reduce myocardial inflammatory injury and fibrosis， and the mechanism is related to inhibiting the activation of NLRP3/AIM2 inflammasomes.

Pulmonary hypertension （PH） is a severe and rare chronic cardiopulmonary disorder for which existing vasodilator therapies can only alleviate symptoms， rather than target or fundamentally reverse the disease. Additionally， the long-term prognosis remains poor. Recent studies have found that some novel anti-tumor drugs （NADs） can relieve PH， such as imatinib， gefitinib， sorafenib， olaparib， piperacillin， everolimus， rituximab， etc. However， some NADs can induce PH or exacerbate its symptoms， including dasatinib， lorlatinib， carfilzomib， bevacizumab， trastuzumab， nivolumab， etc. The effects of lapatinib， ruxolitinib， and bortezomib on PAH are controversial. Individualized medication should be adopted in clinical practice when using NADs for treatment， with close monitoring being essential.

This article summarized Professor YAN Xiaoping's clinical experience in treating enthesitis-related juvenile idiopathic arthritis （ERA）. The core pathogenesis of ERA is identified as kidney deficiency with pathogenic invasion， for which the basic treatment principle is tonifying the kidney and eliminating the pathogen. ERA is classified into "two stages and three syndromes" for differentiation and treatment. In the acute stage， the pathogenesis is primarily kidney deficiency with pathogen excess； for heat syndrome， it is suggested to tonify the kidneys and clear heat， using a self-made Bushen Qingre Lijie Decoction （补肾清热利节汤）； for cold syndrome， the treatment is to tonify the kidneys and expel cold， using a self-made Bushen Qyuhan Lijie Decoction （补肾祛寒利节汤）. In the remission stage， the pathogenesis is primarily spleen and kidney deficiency， and the basic treatment principle is to tonify the kidneys and fortify the spleen， and strengthen bones and muscles， for which self-made Bushen Jianpi Lijie Decoction （补肾健脾利节汤） is recommended.

Objective To explore the effective induction scheme for differentiation of adipose-derived mesenchymal stem cell (ADMSC) to insulin producing cell (IPC). Methods Different schemes of small molecule compound were used to induce the differentiation of ADMSC. The purity of cells was analyzed by flow cytometry and the morphological changes of cells were observed under the microscope. The quality, performance and insulin related indicators of cells were detected by hematoxylin-eosin and immunohistochemical staining. The maturity and activity of cells were detected by dithizone (DTZ) and diacetylfluorescein/propidium iodide staining. The induction effect of ADMSC differentiated into IPC was analyzed. Results The purity of ADMSC reached more than 99%, and the sphere forming properties of schemes Ⅰ, Ⅱ and Ⅲ were good. Cell induction mass, the expression effects of pancreatic and duodenal homeobox 1 (PDX1), musculoaponeurotic fibrosarcoma oncogene homolog A (MAFA) and insulin and C peptide of schemes Ⅰ were both better than those of other schemes. The DTZ staining depth may be related to IPC maturity, among which the number of apoptotic cells in scheme Ⅰ was significantly less than that of scheme Ⅱ and Ⅲ. Conclusions Induction scheme Ⅰ may improve the differentiation efficiency of ADMSC to IPC and lay a certain foundation for future clinical IPC transplantation applications.

BACKGROUND:Osteoblasts are the main cell types responsible for bone formation and remodeling,and the normal performance of their function is precisely regulated by various signaling pathways.Among them,the bone morphogenetic protein and Wnt signaling pathways play a key role in osteogenesis. OBJECTIVE:To review the role of bone morphogenetic protein/Wnt signaling pathway in the regulation of osteoblast function and analyze its changes in different physiological and pathological conditions in order to further reveal the molecular mechanism of bone formation and remodeling. METHODS:The Chinese and English search terms"BMP signaling pathway,Wnt signaling pathway,and osteogenesis"were searched in CNKI,Wanfang,and PubMed databases for original researches published from the inception to June 2023.Totally 61 articles were finally selected for analysis and summary.Using the method of the literature review,the studies of the bone morphogenetic protein/Wnt signaling pathway in regulating osteogenesis were sorted out and analyzed. RESULTS AND CONCLUSION:(1)Bone morphogenetic protein and Wnt signaling pathways play important roles in the differentiation,proliferation,and maturation of osteoblasts.Bone morphogenetic protein signaling pathway mainly regulates the expression of osteogenesis-related genes through the activation of Smad protein.Smad protein enters the nucleus and regulates the expression of genes related to osteogenesis.Different Wnt signaling pathway from bone morphogenetic protein mainly depends on the activation of β-catenin to exert its biological effects.(2)The regulatory effect of bone morphogenetic protein/Wnt signaling pathway will be affected by many factors in different physiological and pathological states.Growth factors,hormones,and mechanical stress can affect the activity of bone morphogenetic protein/Wnt signaling pathway to some extent.(3)Bone morphogenetic protein/Wnt signaling pathway interacts with other signaling pathways in the regulation of osteogenesis,and they together constitute a complex regulatory network.(4)Chinese medicine and natural compounds can promote bone health by regulating signaling pathways,providing new possibilities for treating bone diseases.(5)Future studies can further explore the interaction of bone morphogenetic protein/Wnt signaling pathway and other signaling pathways and its changes in different physiological and pathological conditions,resolve the key nodes and regulation mechanism in the complex network,to provide more precise targets for the treatment of bone-related diseases,and also provide new ideas to reveal the molecular mechanism of bone formation and remodeling.

Objective To investigate the clinical efficacy of β-blockers in older patients with hypertension combined with vascular dementia.Methods A total of 152 older patients with hypertension combined with vascular dementia who were admitted to Shanxi Provincial Fenyang Hospital between January 2022 and October 2024 were enrolled.The participants were randomly assigned to either the study group or the control group(76 patients each)using the randomized numerical table method.Both groups received conventional treatment,and the study group received metoprolol for 5 weeks in addition to the conventional treatment.Primary outcome indicators,including changes in systolic blood pressure(SBP)and diastolic blood pressure(DBP)before and after treatment,were examined.Additionally,comparison was made to examine the intergroup difference in serological markers,including high-sensitivity C-reactive protein(hs-CRP),tumor necrosis factor-α(TNF-α),interleukin(IL)-6,IL-8,matrix metalloproteinase 9(MMP-9),homocysteine(Hcy),and superoxide dismutase(SOD)levels,and the scores for intelligence,cognitive,and behavioral assessments.Adverse reactions were recorded.Results After treatment,the study group showed reduced SBP from(146.90±7.35)mmHg(1 mmHg=0.133 kPa)to(120.00±6.03)mmHg and reduced DBP from(90.24±5.97)mmHg to(77.23±6.81)mmHg.The reduction in blood pressure in the study group became more significantly when compared with that of the control group,with intergroup difference in SBP reduction being-8.54 mmHg(P<0.001)and intergroup difference in DBP reduction being-10.80 mmHg(P<0.001).Patients in the 2 groups showed statistically significant differences in the levels of hs-CRP,TNF-α,IL-6,IL-8,MMP-9,and Hcy,and in their cognitive and behavioral scores(P<0.05).No statistically significant differences were found in pulse pressure,von Willebrand factor(vWF)levels,or intelligence scores before and after treatment(P>0.05).The main adverse reactions in the study group were central nervous system reactions(22.37%)and withdrawal syndrome(17.11%).Conclusion The β-blocker metoprolol effectively controlled blood pressure,significantly reduced levels of pro-inflammatory factors and specific vascular injury markers,and improved cognitive function and behavioral symptoms in older patients with hypertension combined with vascular dementia,suggesting its therapeutic efficacy for this condition.However,attention should be paid to its associated adverse reactions.

Objective:To investigate the anatomical feasibility of the endoscopic transorbital approach (ETOA) to the orbital apex and lateral middle cranial fossa, to identify stable and recognizable surgical landmarks under endoscopic visualization, and to provide morphometric data for preoperative planning and intraoperative navigation.Methods:Stepwise anatomical dissection was performed on five formalin-fixed cadaveric heads and one fresh arterially injected cadaveric specimen to simulate the ETOA using a 0° endoscope. Key structures and their anatomical relationships were observed and recorded. Additionally, high-resolution CT scans of 50 adults were retrospectively analyzed. Three-dimensional reconstructions and measurements were performed using Mimics 17.0 software. Spatial validation was performed using 17 dry skulls to verify the consistency and reliability of osseous anatomical landmarks.Results:Cadaveric dissection identified the meningo-orbital band, superior orbital fissure, optic canal, foramen rotundum, and foramen ovale as reliable surgical landmarks for the ETOA. A topographic map of the surgical region was established based on the endoscopic view. CT measurements revealed the following distances (Mean±SD): the midpoint of the supraorbital rim to the foramen rotundum (57.31±3.59) mm and foramen ovale (71.46±3.42) mm; the lateral orbital rim to the lateral edge of the superior orbital fissure (37.38±2.52) mm; the distance from the superior orbital fissure to the optic canal (9.98±1.49) mm; and the distance from the anterior ethmoidal artery to the optic canal (19.98±2.05) mm. These measurements were consistent with dry skull data, indicating that these osseous landmarks had stable spatial relationships and were suitable for intraoperative localization.Conclusions:The ETOA provides favorable anatomical accessibility and clinical feasibility for lesions involving the orbital apex and lateral skull base. Key osseous structures demonstrate high identifiability and stable spatial relationships, serving as critical references for intraoperative navigation and preoperative pathway planning. The quantitative anatomical framework established in this study provides critical morphometric support for minimally invasive surgery targeting lesions in this region.
