OBJECTIVE To explore and establish a full-cycle management model for drug traceability codes that aligns with national policy requirements and the practical needs of healthcare institutions， thereby enhancing the refinement of drug management and the level of medication safety. METHODS A tripartite strategy integrating “hardware deployment， system transformation， and process re-engineering” was adopted. This involved the introduction of intelligent identification devices （personal digital assistant， high-definition industrial reader）， the modification of the hospital information system interface， and the re-engineering of workflows （drug warehousing， dispensing and distribution， drug withdrawal， uploading to the insurance platform） to achieve comprehensive， informatized collection and association of drug traceability codes throughout all stages. RESULTS A full-cycle management model for drug traceability codes was successfully established， realizing the goals of making drugs “traceable to their source， trackable in their distribution， and accountable in their responsibility”. The patient waiting time for medication dispensing before and after the implementation was [3.08（1.67，5.58）] min and [3.28（1.77，5.98）] min， respectively. Among them， the patient waiting time under the pre-preparation mode was [3.60（2.13，6.35）] min and [3.50（2.03，6.30）] min， respectively； the patient waiting time under the real-time mode was [2.05（0.83，4.03）] min and [2.78（1.18，5.38）] min， respectively； the number of dispensing errors was 3， 0， respectively； the staffing of relevant positions had not been increased. CONCLUSIONS The drug traceability code management model constructed from a full-cycle perspective effectively meets national policy requirements. It provides data support for refined hospital management and offers solid technical and procedural safeguards for ensuring patient medication safety and strengthening medical insurance fund supervision， demonstrating practical value.

Objective:To explore the correlation between inflammatory factor levels in gingival crevicular fluid and pain degree, stress response and masticatory function in patients with combined periodontal and pulpal lesions.Methods:A retrospective selection of 92 patients with combined periodontal and pulpal lesions admitted to Yan ′an People′s Hospital from May 2022 to May 2023 was divided into mild group (60 cases) and moderate-severe group (32 cases) according to the degree of combined periodontal and pulpal lesions. Periodontal clinical indicators were compared between the two groups; enzyme-linked immunosorbent assay (ELISA) was used to detect inflammatory factors in gingival crevicular fluid and serum cortisol (Cor) and adrenocorticotropic hormone (ACTH) levels; Visual Analogue Scale (VAS) was used to evaluate pain degree; and weighing method was used to evaluate masticatory efficiency. Pearson correlation analysis was used to evaluate the correlation between inflammatory factor levels in gingival crevicular fluid and pain degree, stress response and masticatory function.Results:The probing depth (PD), attachment loss (AL), Plaque Index (PLI) and Bleeding Index (BI) in the moderate-severe group [(5.35±0.40)mm, (5.98±0.59)mm, 1.22±0.42, 1.28±0.43] were all higher than those in the mild group [(4.23±0.36)mm, (2.53±0.29)mm, 1.05±0.34, 0.80±0.40] (all P<0.05). The levels of interleukin-1β (IL-1β), interleukin-17 (IL-17) and high-sensitivity C-reactive protein (hs-CRP) in gingival crevicular fluid in the moderate-severe group [(41.87±11.78)μg/L, (606.32±59.33)pg/ml, (58.64±10.63)mg/L] were higher than those in the mild group [(30.35±10.53)μg/L, (478.63±43.18)pg/ml, (43.15±9.85)mg/L], and the level of transforming growth factor-β (TGF-β) [(53.98±6.98)μg/L] was lower than that in the mild group [(121.67±12.87)μg/L] ( P<0.05). The serum Cor and ACTH levels in the moderate-severe group [(165.68±34.64)μg/L, (25.97±6.37)ng/L] were higher than those in the mild group [(148.73±29.65)μg/L, (17.97±5.34)ng/L] (all P<0.05). The VAS score in the moderate-severe group [(5.03±1.20)points] was higher than that in the mild group [(3.57±1.01)points] ( P<0.05). The bite force and masticatory efficiency in the moderate-severe group [(95.32±23.73)lbs, (65.97±13.34)%] were lower than those in the mild group [(113.75±26.46)lbs, (75.89±16.86)%], and the gingival index (1.41±0.50) was higher than that in the mild group (0.85±0.36) (all P<0.05). Correlation analysis showed that IL-1β was positively correlated with disease degree, periodontal indexes, IL-17 and inflammatory factors, and negatively correlated with TGF-β; IL-17 was positively correlated with disease degree and multiple indexes, and negatively correlated with TGF-β, bite force and masticatory efficiency; TGF-β was positively correlated with bite force and masticatory efficiency, and negatively correlated with disease degree and multiple indexes. Conclusions:Inflammatory factors in gingival crevicular fluid of patients with combined periodontal and pulpal lesions are closely related to pain and stress response, and affect masticatory function. In diagnosis and treatment, inflammatory status should be comprehensively considered to provide a basis for personalized treatment.

BACKGROUND:Recent studies have shown that Du Meridian electroacupuncture has a unique effect on alleviating spinal cord injury,but the underlying mechanisms require further clarification.OBJECTIVE:To investigate the regulatory effects and the associated action mechanisms of Du Meridian electroacupuncture on ferroptosis after cervical spinal cord injury in rats.METHODS:One hundred SD rats were randomly divided into sham,model,Du Meridian electroacupuncture,RSL3,and Du Meridian electroacupuncture+RSL3 groups.The sham group underwent only laminectomy.The other four groups were subjected to cervical spinal cord injury by the Allen method.The Du Meridian electroacupuncture group received electroacupuncture after cervical spinal cord injury.The RSL3 group received intraperitoneal injections of glutathione peroxidase 4 inhibitor RSL3 after cervical spinal cord injury.The Du Meridian electroacupuncture+RSL3 group received both electroacupuncture and RSL3 intervention after cervical spinal cord injury.Samples were collected on postoperative days 7 and 28 to assess motor function,histological morphology,neuronal survival,glial scar formation,oxidative stress levels,Fe2+content,glutathione peroxidase 4,and long-chain acyl-CoA synthetase 4 expression.RESULTS AND CONCLUSION:(1)Finally,90 rats completed the follow-up experiment,with 18 rats in each group.(2)FLS and BBB scores were significantly higher in the Du Meridian electroacupuncture group compared with the model and Du Meridian electroacupuncture+RSL3 groups(P＜0.05).(3)Compared with the model group,Du Meridian electroacupuncture improved cervical spinal cord tissue morphology and mitochondrial ultrastructure,while these effects were inhibited by RSL3.(4)Du Meridian electroacupuncture increased the expression of microtubule-associated protein 2,glutathione peroxidase 4,glutathione,and superoxide dismutase(P＜0.05)and reduced the expression of glial fibrillary acidic protein,long-chain acyl-CoA synthetase 4,reactive oxygen species,malondialdehyde,and Fe2+compared with the model group(P＜0.05).However,RSL3 reversed the inhibitory effects of Du Meridian electroacupuncture on ferroptosis,lipid peroxidation and oxidative stress.(5)The results suggest that Du Meridian electroacupuncture inhibits ferroptosis by regulating the glutathione peroxidase 4/long-chain acyl-CoA synthetase 4 axis,thereby reducing secondary neuronal damage and glial scar formation after cervical spinal cord injury and improving neurological function.

AIM:To investigate the effect of dyes,Remazol BrOrange yellow(RBY)and erythrosine(ERY),on the outcomes of immunoblotting analysis when used for staining the concentrate gel in sodium dodecyl sulfate-polyacryl-amide gel electrophoresis(SDS-PAGE).METHODS:Polyacrylamide gels were divided into five groups:the control group(prepared according to the conventional kit protocol),the RBY-stained group with a final concentration of 0.08 g/L,the RBY-stained group with a final concentration of 0.16 g/L,the ERY-stained group with a final concentration of 0.08 g/L,and the ERY-stained group with a final concentration of 0.8 g/L.Gels were prepared and subjected to electro-phoresis,followed by coomassie brilliant blue staining to visualize protein bands.Subsequently,proteins were transferred to PVDF membranes,which were then blocked,incubated with primary and secondary antibodies,washed,and finally ex-posed for imaging to observe the target protein vinculin bands.RESULTS:Compared with the unstained concentrate gel,the loading wells of the RBY or ERY pre-stained concentrate gel were more clearly visible.Analysis of the gels stained with coomassie brilliant blue after electrophoresis and marker visualization showed no significant different in protein elec-trophoretic mobility between prestained and unstained gels.Comparative analysis of the immunoblotting also indicated that the detection of protein samples transferred to PVDF membranes was unaffected.CONCLUSION:Prestaining concen-trate gels with RBY or ERY can enhance the efficiency of gel-based electrophoresis and immunoblotting analysis.

OBJECTIVE To provide technical support for improving recognition rate of adverse drug events （ADEs） related to traditional Chinese medicine （TCM） formula granules and decoction pieces among inpatient patients. METHODS By referencing the global trigger tool （GTT） whitepaper， literature on adverse reactions to TCM， and expert review opinions， ADE trigger items for TCM formula granules and decoction pieces used in the inpatients were established. GTT was applied to analyze ADEs in inpatients who had used TCM formula granules and decoction pieces in our hospital from August 2013 to August 2023， utilizing the Chinese Hospital Pharmacovigilance System. The effectiveness of GTT and the characteristics of these ADEs were analyzed. RESULTS A total of forty-eight triggers were established， including thirty-two laboratory test indexes， thirteen clinical symptoms， and three antidotes. Among the 1 682 patients included， GTT identified 652 potential ADEs， 284 true positive ADEs，with a trigger rate of 38.76% and a positive predictive value of 43.56%. After review by the auditor， 278 cases of ADEs were finally confirmed， with an incidence rate of 16.53%， significantly higher than the number of spontaneously reported ADEs during the same period （0）. The 278 cases of ADEs were mostly grade 1 （223 cases）， mainly involving hepatobiliary system， gastrointestinal system， blood- lymphatic system， etc；a total of 219 types of TCMs are involved，and the top five suspected TCMs used at a frequency higher than 1% were Poria cocos， Codonopsis pilosula， Atractylodes macrocephala， fried Glycyrrhiza uralensis， and Scutellaria baicalensis. CONCLUSIONS The established GTT can improve the recognition rate of ADEs for hospitalized patients using traditional Chinese medicine formula granules and decoction pieces.

BACKGROUND:Various proteins,signaling pathways,and inflammatory mediators are involved in the pathophysiological process of osteoarthritis.The development of small molecule drugs targeting these proteins,signaling pathways,and inflammatory mediators can effectively delay the progression of osteoarthritis and ameliorate its clinical manifestations. OBJECTIVE:To review the research progress of small molecule drugs in the treatment of osteoarthritis based on the pathogenesis of osteoarthritis. METHODS:PubMed,CNKI,and WanFang databases were searched with English search terms"osteoarthritis,arthritis,osteoarthrosis,degenerative,arthritides,deformans,small molecule drugs,small molecule inhibitors,small molecule agents"and Chinese search terms"osteoarthritis,small molecule drugs,small molecule inhibitors."A total of 68 articles were included for review according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION:(1)Currently,studies concerning the pathogenesis of osteoarthritis remain unclear.The occurrence and development of osteoarthritis are strongly associated with proteins,cytokines,and signal transduction pathways,so its therapeutic mechanism is relatively complex.Currently,targeting proteins,cytokines,and signal transduction pathways related to osteoarthritis with small molecule drugs has become a major research focus.(2)Small molecule drugs frequently possess visible intracellular or extracellular targets and efficacy,containing enhancing cartilage repair,resisting joint degradation,attenuating inflammation,and relieving pain.Other anti-osteoarthritis small molecule drugs have shown promise in promoting stem cell chondrogenic differentiation and cartilage matrix reconstruction.(3)At present,small molecule drugs targeting the pathophysiological process of osteoarthritis to delay the progression of osteoarthritis are still in the experimental stage,but most of these small molecule drugs have shown the expected results in the experimental process,and there are no relevant studies to illustrate the efficacy of small molecule drugs in the treatment of osteoarthritis.(4)Small molecule drugs for the treatment of osteoarthritis have reached the expected experimental results in the basic experimental stage.Numerous studies have exhibited that small molecule drugs can target the suppression of specific proteins,cytokines,and signal transduction pathways that cause osteoarthritis,so as to treat osteoarthritis.Nevertheless,its safety and effectiveness still need to be identified by further basic and clinical studies.This process needs to be investigated and studied by more scholars.(5)At present,many scholars in and outside China have made contributions to the treatment of osteoarthritis.Compared with traditional treatment methods,small molecule drugs reveal better efficacy and safety in the basic experimental stage,and it is expected to become an emerging method for the treatment of osteoarthritis in the future to rid patients of pain.

Objective:To analyze the epidemiological and clinical characteristics of respiratory pathogens in China.Methods:This study was a cross-sectional study, which encompassed 19 core units of the clinical pathogen network and established a three-tiered clinical pathogen surveillance system. Thirty respiratory samples were collected every two weeks from various units from January to December 2024, and the clinical and pathogen diagnostic information were gathered. A total of 11 864 samples were tested using this system. The tier-1 clinical pathogen surveillance system covered influenza A virus (Flu-A), influenza B virus (Flu-B), respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The tier-2 clinical pathogen surveillance system focused on 18 key respiratory pathogens. The tier-3 clinical pathogen surveillance system further clarified whether any emerging infectious diseases had occurred.Results:The tier-1 clinical pathogen surveillance system showed Flu-A predominated in December, Flu-B predominated in January, SARS-CoV-2 peaked in March and August, whereas RSV circulated sporadically throughout the year. Geographic trends were broadly consistent across the seven major regions, although Flu-A detection in December was notably higher in Northeast China (48.1%(111/231)) and East China (36.2%(148/409)), and RSV detection was concentrated in the Northwest and South China from January to March. Data from the tier-2 clinical pathogen surveillance system indicated that Streptococcus pneumoniae, Mycoplasma pneumoniae, rhinovirus, and adenovirus were detected year-round, of these, Streptococcus pneumoniae and rhinovirus showed elevated positive detection rates from August to September, while adenovirus peaked in January. Legionella pneumophila was not detected throughout the year, and other pathogens fluctuated throughout the year without a consistent pattern. The predominant etiologic agents of pediatric pneumonia were Mycoplasma pneumoniae (35.0%(105/300)), rhinovirus (25.7%(77/300)), and adenovirus (17.3%(52/300)), whereas adult pneumonia was mainly caused by Streptococcus pneumoniae (10.5%(29/277)), Staphylococcus aureus (6.9%(19/277)), Mycoplasma pneumoniae (6.9%(19/277)), and Flu-A (6.1%(17/277)). The tier-3 clinical pathogen surveillance system did not identify any emerging respiratory pathogens. Conclusion:Respiratory pathogens in China in 2024 exhibit distinct temporal and spatial distribution patterns and vary among different populations.
