OBJECTIVE To provide a basis for aligning Chinese pharmacoeconomic research on heart failure （HF） with international standards. METHODS A qualitative comparison o f domestic and global HF pharmacoeconomic studies was conducted across four dimensions： research methods and model application， research perspectives and endpoints， data sources and parameter selection， and policy translation and practical impact. RESULTS & CONCLUSIONS Global studies predominantly utilize long-term dynamic models， societal perspectives， real-world data integration， and directly inform reimbursement decisions. Conversely， domestic research often relies on short-term simplified models， a single healthcare system perspectives， literature-derived data， and individual medicine recommendations. Future domestic studies should transition to long-term dynamic modeling， develop localized disease-specific utility databases via big data， establish reimbursement-linked closed-loop mechanisms， and foster multidisciplinary collaboration to optimize healthcare resource allocation.

Obesity and its related metabolic diseases have become a major global public health threat, and its rising incidence significantly increases the risk of cardiovascular and cerebrovascular diseases, diabetes and other complications. Pancreatic lipase is a key enzyme that converts food-borne lipids into triglycerides and fatty acids, and the effective inhibition of its activity has become an important strategy for the treatment of obesity. This paper discusses the screening methods of pancreatic lipase inhibitors, and summarizes and reviews the basic principles, advantages and disadvantages and application status of traditional screening methods, modern new screening methods and virtual screening methods. In view of the problems faced by the screening methods of pancreatic lipase inhibitors, future research urgently needs to move towards a collaborative innovation path of multi-technology integration, intelligent screening and complex systematization of traditional Chinese medicine, so as to open up new research paradigms.

Objective: To fabricate a hydrogel loaded with inositol hexaphosphate-zinc and preliminarily evaluate its performance in self-mineralization and osteoinduction, thereby providing a theoretical basis for the development of bone regeneration materials. Methods: The hydrogel framework (designated DF0) was formed by copolymerizing methacryloyloxyethyltrimethylammonium chloride and four-armed poly(ethylene glycol) acrylate, followed by sequentially loading inositol hexaphosphate anions via electrostatic interaction and zinc ions via chelation. The hydrogel loaded only with inositol hexaphosphate anions was named DF1, while the co-loaded hydrogel was named DF2. The self-mineralization efficacy of the DF0 , DF1 and DF2 hydrogels was characterized using scanning electron microscopy, transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and selected area electron diffraction (SAED). The biocompatibility was assessed via live/dead cell staining and a CCK-8 assay. The osteoinductive capacity of the DF0 , DF1 and DF2 hydrogels on MC3T3-E1 cells was assessed via alkaline phosphatase (ALP) and Alizarin Red S (ARS) staining. In the aforementioned cell experiments, cells cultured in standard medium served as the control group Results: The DF0, DF1, and DF2 hydrogels were successfully synthesized. Notably, DF1 and DF2 exhibited distinct self-mineralization within 6 days. Results from TEM, EDS, and SAED confirmed that the mineralization products were amorphous calcium phosphate in group DF1, and amorphous calciumzinc phosphate in group DF2. Biocompatibility tests revealed that none of the hydrogels (DF0, DF1, and DF2) adversely affected cell viability or proliferation. In osteogenic induction experiments, both ALP and ARS staining were intensified in the DF1 and DF2 groups, with the most profound staining observed in the DF2 group. Conclusion The developed inositol hexaphosphate-zinc hydrogel (DF2) demonstrates the dual capacity to generate calcium-phosphate compounds through self-mineralization while exhibiting excellent osteoinductive properties. This biocompatible, dual-promoting osteogenic hydrogel presents a novel strategy for bone regeneration.

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.

To systematically synthesize evidence on multiple KRAS G12C inhibitors(KRAS G12C inhibitors, KRAS G12Ci) as monotherapy within a unified population and recommended-dose framework, establish a comparable benchmark range of efficacy and safety for previously treated patients with advanced or metastatic KRAS G12C-mutant non-small cell lung cancer(NSCLC), and explore potential effect modifiers.

OBJECTIVE To investigate the stability and compatibility of butorphanol， nicardipine， urapidil， and tirofiban. METHODS A micro-infusion pump was used to simulate the infusion process. Samples were collected in real time from the needle tip at 0， 2， 4， 6， and 8 h after mixing of the four drugs. The appearance， pH， and number of insoluble particles were examined. The contents of butorphanol， nicardipine， urapidil， and tirofiban were determined using the ultra-high-performance liquid chromatography method. RESULTS Within 8 hours， all mixed solutions remained clear and transparent， with no visible turbidity， precipitation， color change， or gas generation. The pH fluctuation ranged from 0.02 to 0.09， both within 0.1 pH units. The number of insoluble particles ≥10 μm in size in each compatibility solution was ≤9， and the number of insoluble particles ≥25 μm was ≤2， meeting the requirements of the 2025 edition of the Chinese Pharmacopoeia （Volume Ⅳ）. The relative percentage contents of butorphanol， nicardipine， urapidil， and tirofiban at 8 hours after compatibility mixing ranged from 92.38% to 113.40%. CONCLUSIONS Within 8 hours under simulated clinical micro-infusion pump infusion conditions， the stability and compatibility of the mixed solution containing butorphanol， nicardipine， urapidil， and tirofiban were satisfactory.

Objective To investigate whether the pyroptosis-related Toll-like receptor 4(TLR4)signaling pathway influences the malignant transformation of actinic keratosis(AK)into cutaneous squamous cell carcinoma(SCC).Methods A total of 6 lesion tissue samples each from patients with AK and SCC,as well as 5 normal skin tissue samples from healthy subjects as controls,were collected from the First Affiliated Hospital of Kunming Medical University between August 2020 and August 2021.Quantitative PCR(qPCR)and Western blot analysis were performed to determine the mRNA and protein expression levels of TLR4 pathway-related factors,including TLR4,CPB1,NLRP3,IL-1β,and IL-18.TLR4/TUNEL double immunofluorescence staining was used to evaluate TLR4 expression and the level of cellular pyroptosis in tissue samples.In addition,Western blotting was performed to analyze the expression differences of pyroptosis-related core proteins(pro-caspase-1,cleaved caspase-1/p20,GSDMD,and cleaved N-terminal GSDMD)and TLR4 among the normal keratinocyte cell line HaCaT and SCC cell lines A431 and SCL-1.Results Quantitative PCR and Western blot results showed that the mRNA and protein expression levels of TLR4,CPB1,NLRP3,IL-1β,and IL-18 were significantly higher in SCC tissues than in AK and normal skin tissues(P<0.05).TLR4/TUNEL double immunofluorescence results revealed a progressive increasing trend in TLR4 expression and pyroptosis levels from normal skin to AK and further to SCC(P<0.05).Furthermore,in SCL-1 cells,the expression levels of pro-caspase-1,cleaved caspase-1/p20,cleaved N-terminal GSDMD,and TLR4 were significantly upregulated(P<0.05),whereas in A431 cells,only TLR4 expression was increased(P<0.05),and the levels of other pyroptosis-related proteins were downregulated compared to HaCaT cells(P<0.05).Conclusion The expression of the TLR4 signaling pathway gradually increased from AK to SCC,and its activation status varied among different cutaneous squamous cell carcinoma cell lines.

Objective:To investigate the differences in clinical characteristics and antibiotic resistance of neonatal sepsis（NS）caused by different Gram-staining pathogens.Methods:A retrospective study was conducted on confirmed NS cases admitted to the Neonatal Ward of the Pediatric Department at The First Affiliated Hospital of Dali University，from June 1，2014，to May 31，2024.Patients were divided into Gram-positive and Gram-negative groups based on blood or cerebrospinal fluid（CSF）culture results.Clinical characteristics，pathogen distribution，and antibiotic resistance were compared between the two groups.Results:A total of 98 cases were included，with 81 in the Gram-positive group and 17 in the Gram-negative group.Multivariate logistic regression analysis revealed that NS cases with a high neutrophil percentage（ OR=0.933，95% CI：0.899-0.969）or hemorrhagic symptoms/signs（ OR=0.059，95% CI：0.008-0.458）were less likely to have Gram-positive pathogens detected in blood or CSF cultures（ P<0.05）.Common Gram-positive pathogens included Staphylococcus epidermidis with 35 strains（33.65%）and Staphylococcus hominis with 22 strains（21.15%）.The predominant Gram-negative pathogen was Escherichia coli with 14 strains（13.46%）.Gram-positive pathogens exhibited high resistance to oxacillin（91.30%），erythromycin（90.91%），and penicillin G（90.00%），but low resistance to tigecycline（0），linezolid（0），and vancomycin（0）.Gram-negative pathogens showed high resistance to ampicillin（92.31%），cefazolin（90.00%），and ampicillin/sulbactam（75.00%），but low resistance to amikacin（6.25%），latamoxef（0），and ertapenem（0）.The incidence of concurrent purulent meningitis was lower in the Gram-positive group than in the Gram-negative group（9.88% vs.47.06%， χ2=11.628， P<0.05），and there was significant difference. Conclusion:NS cases with high neutrophil percentages or hemorrhagic symptoms/signs are less likely to be caused by Gram-positive pathogens.Staphylococcus epidermidis and Staphylococcus hominis are common Gram-positive pathogens，while Escherichia coli is the predominant Gram-negative pathogen in NS.Both Gram-positive and Gram-negative pathogens exhibit resistance to specific antibiotics.NS caused by Gram-positive pathogens is less likely to be complicated by purulent meningitis compared to those caused by Gram-negative pathogens.

Objective To investigate the effect and mechanism of miR-155-5p targeting suppressor of cytokine signaling 1(SOCS1)in regulating the Janus kinase 2(JAK2)/signal transducer and activator of transcrip-tion 3(STAT3)signaling pathway in renal injury associated with lupus nephritis(LN).Methods Thirty female MRL-faslpr lupus model mice were randomly divided into five groups(n=6 per group):the model group,the antagomir NC group,the miR-155-5p antagomir group,the miR-155-5p antagomir+shRNA control group,and the miR-155-5p antagomir+SOCS1 shRNA group.The mice were treated with adeno-associated virus vectors carrying miR-155-5p antagomir,antagomir NC,SOCS1 shRNA,or shRNA control.Additionally,six age-matched C57BL/6 mice served as a control group and received an equivalent volume of saline.Serum blood urea nitrogen(BUN)and creatinine(Scr)levels,renal histopathological changes,and the expression levels of miR-155-5p,SOCS1,phosphorylated JAK2(p-JAK2),and phosphorylated STAT3(p-STAT3)in renal tissues were evaluated.Results Compared with the normal group,the model group exhibited significantly elevated levels of BUN,Scr,miR-155-5p,p-JAK2,and p-STAT3 proteins in the kidneys(P<0.01),while the expression level of SOCS1 was markedly reduced(P<0.01).Compared with both the model group and the antagomir NC group,the miR-155-5p antagomir group showed decreased levels of BUN,Scr,miR-155-5p,p-JAK2,and p-STAT3 proteins(P<0.01),along with a significant increase in SOCS1 expression(P<0.01).Similarly,compared with the miR-155-5p antagomir group and the miR-155-5p antagomir+shRNA control group,the miR-155-5p antagomir+SOCS1 shRNA group demon-strated significantly higher levels of BUN,Scr,miR-155-5p,p-JAK2,and p-STAT3 proteins(P<0.01),while SOCS1 expression was notably decreased(P<0.01).Renal pathology analysis revealed that,compared to the normal group,the model group exhibited glomerular atrophy,extensive infiltration of inflammatory cells in the renal tubulointerstitial region,and partial renal tubular necrosis.In contrast,the miR-155-5p antagomir group showed marked improvements in glomerular atrophy,tubular necrosis,and inflammatory cell infiltration compared with the model group and antagomir NC group.Furthermore,compared with the miR-155-5p antagomir group and the miR-155-5p antagomir+shRNA control group,the miR-155-5p antagomir+SOCS1 shRNA group exhibited more severe glomerular atrophy,tubular necrosis,and inflammatory cell infiltration.Conclusion MiR-155-5p exacerbates renal damage in MRL-faslpr lupus model mice by targeting SOCS1,potentially through the activation of the JAK2/STAT3 signaling pathway.
