In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

Objective To investigate the significance of intratumoral and peritumoral radiomics models in predicting occult lymph node metastasis in stage T1 non-small cell lung cancer(NSCLC)and to compare the predictive accuracy in different peritumoral radiomics models.Methods The CT images and clinical data of 211 patients without lymph node metastasis on preoperative CT examination and pathologically confirmed NSCLC after surgery were collected.The radiomics features were derived from the three-dimensional volume of interest(VOI)of the intratumoral and peritumoral at 3-,5-,and 10-mm following lesion segmentation on CT images of each patient.The feature data of all nidus were radomly divide into training set and validation set with a ratio of 7︰3.The Pearson or Spearman correlation test was performed to remove redundancy.Dimensionality was reduced by the least absolute shrinkage and selection operator(LASSO)regression analysis.The linear combination of selected features and corresponding coefficients were used to construct the Radiomics score(Radscore).The clinical model and comprehensive model were constructed by logistic regression analysis.The conprehensive model was visualized with the nomogram,and its performance was evaluated.Results Among the peritumoral radiomics models,the peritumoral 5-mm model showed the best predictive efficacy[validation set,area under the curve(AUC)0.771].The comprehensive model containing Radscore,CT image features and CEA exhibited the best performance(validation set,AUC 0.850).Conclusion Intratumoral and peritumoral radiomics models perform efficiently in predicting occult lymph node metastasis in stage T1 NSCLC,and nomogram can effectively and noninvasively predict occult lymph node metastasis in NSCLC.

Objective To explore the effect of miRNA-222-3p in endothelial progenitor cell-derived exosomes(EPCs-Exo)on skin wound healing in diabetic mice.Methods Endothelial progenitor cell(EPCs)derived from C57BL/6 mouse bone marrow were identified by fluorescence staining.Subsequently,EPCs-Exo isolated from the media of EPCs were identified,and high-throughput sequencing of EPCs-Exo miRNA was completed.The skin injury model of diabetic mice was established.According to different groups,the wounds were treated with externally ap-plied phosphate buffer solution(PBS)and EPCs-Exo;Subcutaneous injection of PBS,agomiR-222-3p,and an-tagomiR-222-3p at the edge of the wound was performed continuously for 14 days,and the wound healing rate was observed.Meanwhile,immunofluorescence methods were used to investigate the changes in the expression levels of ROS,CD31,and VEGF in the wound margin tissue before and after treatment.Results EPCs-Exo significantly ac-celerated skin wound healing in diabetic mice,reduced the level of ROS,and increased the expression level of VEGF and CD31 in the wound margin tissue(P＜0.05).High-throughput sequencing showed that miRNA-222-3p was highly expressed in EPCs-Exo.Local subcutaneous injection of miRNA-222-3p into wound margin tissue signifi-cantly promoted the skin wound healing of diabetic mice,reduced the level of ROS,and increased the expression level of VEGF and CD31 in the wound margin tissue(P＜0.05).Conclusion MiRNA-222-3p promotes wound healing in diabetic mice and plays an important role in EPCs-Exo promoting wound healing.

Objective To investigate the application of intravenous iron in patients with abnormal uterine bleeding(AUD)and iron deficiency anemia(IDA)in gynecology,to establish the drug utilization evaluation(DUE)standard,and to comprehensively evaluate the rationality of the clinical application of intravenous iron by analytic hierarchy process(AHP),so as to provide reference for the rational use of intravenous iron in clinical practice.Methods The medical records of patients with AUD and IDA from January to December 2022 in the First Affiliated Hospital of Anhui University of Science and Technology were collected,and the special rationality of the drug was evaluated from the aspects of indications,route and frequency of administration,daily dosage,solvent,combination medication,and contraindications of iron sucrose injection,and the DUE standard of the drug was formulated.AHP was used to analyze and evaluate 113 archived cases of intravenous iron in gynecology from January to December 2022.Results A total of 113 patients were treated with iron sucrose injection,and the indications,route of administration,solvent,contraindications,and allergic reactions were reasonable.The main unreasonableness was that the frequency of administration was inappropriate,the daily dose was inappropriate,the combination was not appropriate,the total iron supplement was not up to standard,and there was no continuous drug monitoring after medication.The case scores 90～100,70～<90 and 60～<70 were 6(5.31%),106(93.81%)and 1(0.88%),respectively.Conclusion Patients with AUD and IDA should pay attention to the dosage,total amount of iron supplementation,combined application of drugs and continuous medication monitoring after intravenous iron supplementation,so as to improve the rationality of their use.

Objective To provide pharmaceutical monitoring using the Pharmaceutical Care Network Europe(PCNE)for patients with respiratory diseases,to explore effective pharmaceutical monitoring models in the department of respiratory,and to promote clinical rational drug use.Methods Inpatients diagnosed with chronic obstructive pulmonary disease(COPD)and lung infections in 2022 at the First Affiliated Hospital of Anhui University of Science and Technology were selected and divided into a simple group and an intervention group.According to the PCNE classification system,the types,causes,interventions,acceptance of interventions,and resolution status of drug-related problems(DRPs)were analyzed.Results A total of 120 cases were included,60 cases in the simple group and 60 cases in the intervention group.Regarding the number of DRPs,there were 15 cases in the simple group and 45 cases in the intervention group,and there was a significant difference between the two groups(P<0.05).There were a total of 82 DRPs,which were mainly related to therapeutic efficacy(51.22%)and safety(46.34%),and the reasons for this were that patients'incorrect medication usage method,inappropriate usage and dosage,and unscheduled safety monitoring,etc.The pharmacist interventions were 75(91.46%)at the drug level,38(46.34%)at the physician level,and 43(52.44%)at the patient level;after the pharmacist interventions,the acceptance rate was in the range of 97.56%,and 74.39%of the DRPs were resolved.Conclusion PCNE classification system helps clinical pharmacists to enhance their ability to find and deal with DRPs,reduce the risk of clinical adverse events and promote reasonable and safe drug use.Meanwhile,it is conducive to the standardization of pharmaceutical care records for patients with respiratory diseases and provides reference for pharmaceutical service models for patients in the department of respiratory.

Objective:To investigate the clinical effect of intraarticular vancomycin on early periprosthetic joint infection (PJI) in knee arthroplasty and the incidence of postoperative complications.Methods:This is a retrospective cohort study. The clinical data of 1 867 patients who underwent primary knee arthroplasty at Department of Joint Surgery, the Affiliated Hospital of Qingdao University from April 2022 to June 2023 were retrospectively analysed, including total knee arthroplasty (TKA), robotic-assisted total knee arthroplasty (RA-TKA) and unicondylar knee arthroplasty (UKA). There were 687 males and 1 180 females, aged (68.0±11.2)years(range:45 to 87 years). Patients were divided into the vancomycin group and the control group according to whether or not intra-articular injection of 1 g of vancomycin powder dissolved in 30 ml of saline was performed after intraoperative joint capsule closure. In the vancomycin group, 925 patients were included, including 782 TKA, 27 RA-TKA and 116 UKA.In the control group, 942 patients were included, including 767 TKA, 99 RA-TKA and 76 UKA. Early PJI, wound complications, and vancomycin-related toxicity including acute renal collapse, ototoxicity, and allergic reactions were assessed within 3 months postoperatively. The data were compared using the independent sample t test, χ2 test, and Fisher's exact probability method, as appropriate. Major Extremity Trauma Research Consortium (METRC). Results:No PJI was found in all patients in the vancomycin group.Five cases (0.7%,5/767) of early PJI were found in TKA patients in the control group, with a statistically significant difference ( P=0.030); 1 case of early PJI was found in each RA-TKA and UKA patients, with non-significant difference compared with vancomycin group (all P>0.05). Two cases (0.3%,2/782) of incisional complications were found in TKA patients in the vancomycin group, and 4 cases (0.5%, 4/767) of incisional complications were found in TKA patients in the control group, with non-significant difference( P=0.449); no incisional complication was found in RA-TKA patients in the vancomycin group, and 1 case (1.0%,1/99) of incisional complications were found in RA-TKA patients in the control group, the difference was not statistically significant ( P>0.05); no incisional complication was found in both groups of UKA patients.No vancomycin-related acute kidney injury, ototoxicity, or allergic reactions was observed in all patients. Conclusion:Intra-articular injection of 1 g of vancomycin suspension after arthrotomy closure during TKA maybe lower the risk of early PJI without increasing the risk of wound complication and vancomycin-associated systemic toxicity.
