OBJECTIVE To upgrade the drug traceability code management system for a pediatric hospital under the “payment by code” background， aiming to comprehensively enhance traceability integrity， efficiency， and compliance. METHODS Taking Xiamen Children’s Hospital as the implementation setting， a before-and-after control design was adopted to construct an intelligent drug traceability code management system through systematic upgrades involving the technology platform， core mechanisms， and coordination with medical insurance. Key interventions included： upgrading a traceability code management platform and designing a dynamic code pool； innovating differentiated traceability mechanisms for routine， split-dose， and special drugs； establishing a tiered early-warning and emergency response system； and constructing a data coordination and quality control system. The drug traceability code upload rate served as the primary outcome. Process indicators such as the root causes distribution of failed uploads and the duration of medication returns， and a comprehensive outcome （the number of insurance-flagged abnormal prescriptions） were also analyzed. The data between the baseline period （April 2025） and the observation period （June-August 2025） were compared and evaluated. RESULTS After the upgrade， the overall upload rate of drug traceability codes increased from 9.21% （baseline） to 99.86% （August 2025）. The upload rate of traceability codes in previously unmanaged areas， such as the inpatient pharmacy and pharmacy intravenous admixture services， soared from 0 to nearly 100%. The proportion of non-uploads due to system issues fell from 66.44% （June 2025） to 2.62% （August Additionally， the number of insurance-flagged） abnormal prescriptions dropped sharply from 2 275.00 in the first “payment by code” policy month （July 2025） to 212.00 by the end of the observation period （August 2025）， a 90.70% decrease. CONCLUSIONS The developed management system effectively addresses complex scenario challenges such as high-frequency drug splitting. It significantly enhances traceability code upload performance and ensures a high degree of compliance with medical insurance data requirements. These outcomes contribute to proactive risk mitigation against insurance claim denials and demonstrate a concurrent optimization of pharmacy operations.

OBJECTIVE To formulate the Expert Consensus on the Implementation and Management of Drug Selection for Centralized Volume-Based Procurement in Medical Institutions of Guangxi （hereinafter referred to as the “ Consensus ”）， and to provide decision-making support and practical guidance for the drug selection and management of centralized volume-based procurement （hereinafter referred to as “centralized procurement”） drugs in medical institutions at all levels in Guangxi. METHODS A systematic review was conducted on the materials from previous batches of centralized procurement implemented in Guangxi. A comprehensive search was carried out for drug-related works and books， along with a systematic collation of guidelines on drug selection， expert consensus on centralized procurement， and policy documents. Through three rounds of specialized seminars， combined with existing evidence-based data and the practical drug selection experiences of medical institutions at various levels， this Consensus was formulated after thorough discussion and successive rounds of revision. RESULTS & CONCLUSIONS The Consensus systematically outlines the three key stages in the implementation of centralized procurement in medical institutions： procurement volume reporting， confirmation of agreed procurement volume， and procurement and usage implementation. It proposes drug selection strategies for centralized procurement bas ed on multiple dimensions， including specifications， dosage forms， packaging materials， fill volume， and manufacturing enterprises. In response to practical challenges encountered in the selection process， corresponding countermeasures are proposed， such as establishing a regularized information reserve mechanism， strengthening information technology support， and implementing categorized selection approaches. The Consensus advocates for medical institutions to construct an integrated “policy， data， and quality” decision-making system to promote full-cycle management of centralized procurement. This Consensus will provide scientific and practical guidance for medical institutions at all levels in Guangxi in the drug selection of centralized procurement， facilitating the smooth implementation and sustainable development of centralized procurement policies at the institutional level.

ObjectiveTo investigate the influence of entecavir （ETV） versus tenofovir alafenamide fumarate （TAF） on renal function in previously untreated patients with chronic hepatitis B （CHB）. MethodsA retrospective analysis was performed for the clinical data of 167 previously untreated CHB patients who received ETV or TAF treatment for at least 48 weeks at the outpatient service of Department of Infectious Diseases in The First Affiliated Hospital of Nanchang University from September 2019 to November 2023， and according to the antiviral drug used， they were divided into ETV group with 117 patients and TAF group with 50 patients. In order to balance baseline clinical data， propensity score matching （PSM） was used for matching and analysis at a ratio of 2∶1， and the two groups were compared in terms of estimated glomerular filtration rate （eGFR） and the incidence rate of abnormal renal function at week 48. According to eGFR at week 48， the patients were divided into normal renal function group and abnormal renal function group. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The multivariate Logistic regression analysis was used to investigate the influencing factors for abnormal renal function， and the receiver operating characteristic （ROC） curve was used to assess the performance of each indicator in predicting abnormal renal function. The Kaplan-Meier method was used to analyze the cumulative incidence rate of abnormal renal function， and the log-rank test was used for comparison. The analysis of variance with repeated measures was used to compare the dynamic changes of eGFR during antiviral therapy in CHB patients. ResultsAfter PSM matching， there were 100 patients in the ETV group and 50 patients in the TAF group. There were no significant differences in baseline clinical data between the ETV group and the TAF group （all P>0.05）， with an eGFR level of 112.29±9.92 mL/min/1.73 m² in the ETV group and 114.72±12.15 mL/min/1.73 m² in the TAF group. There was a reduction in eGFR from baseline to week 48 in both groups， and compared with the TAF group at week 48， the ETV group had a significantly lower eGFR （106.42±14.12 mL/min/1.73 m² vs 112.25±13.44 mL/min/1.73 m²， t=-2.422， P=0.017） and a significantly higher incidence rate of abnormal renal function （17.00% vs 4.00%， χ²=5.092， P=0.024）. After the patients were divided into normal renal function group with 131 patients and abnormal renal function group with 19 patients， the univariate analysis showed that there were significant differences between the two groups in age （Z=-2.039， P=0.041）， treatment drug （ETV/TAF） （χ²=5.092， P=0.024）， and baseline eGFR level （t=4.023， P<0.001）， and the multivariate Logistic regression analysis showed that baseline eGFR （odds ratio ［OR］=0.896， 95% confidence interval ［CI］： 0.841 — 0.955， P<0.001） and treatment drug （OR=5.589， 95%CI： 1.136 — 27.492， P=0.034） were independent influencing factors for abnormal renal function. Baseline eGFR had an area under the ROC curve of 0.781 in predicting abnormal renal function in CHB patients， with a cut-off value of 105.24 mL/min/1.73 m²， a sensitivity of 73.68%， and a specificity of 82.44%. The Kaplan-Meier curve analysis showed that the patients with baseline eGFR≤105.24 mL/min/1.73 m² had a significantly higher cumulative incidence rate of abnormal renal function than those with baseline eGFR>105.24 mL/min/1.73 m² （χ²=22.330， P<0.001）， and the ETV group had a significantly higher cumulative incidence rate of abnormal renal function than the TAF group （χ²=4.961， P=0.026）. With the initiation of antiviral therapy， both the ETV group and the TAF group had a significant reduction in eGFR （F=5.259， P<0.001）， but the ETV group only had a significant lower level of eGFR than the TAF group at week 48 （t=-2.422， P=0.017）； both the baseline eGFR≤105.24 mL/min/1.73 m² group and the baseline eGFR>105.24 mL/min/1.73 m² group had a significant reduction in eGFR （F=5.712， P<0.001）， and there was a significant difference in eGFR between the two groups at baseline and weeks 12， 24， 36， and 48 （t=-13.927， -9.780， -8.835， -9.489， and -8.953， all P<0.001）. ConclusionFor CHB patients initially treated with ETV or TAF， ETV antiviral therapy has a higher risk of renal injury than TAF therapy at week 48.

Objective To investigate the effect of extracellular heat shock protein(HSP)22 on Toll-like receptor(TLR)4/nuclear factor-κB(NF-κB)signaling pathway in oxidative-low-density lipoprotein(ox-LDL)-induced inflammatory damage in coronary endothelial cells(HCAECs).Methods HCAECs were cul-tured in vitro and pretreated with ox-LDL to establish a model of high-lipid-induced endothelial cell injury.Re-combinant human HSP22(rhHSP22)was exogenously treated.The effects of rhHSP22 on the expression of inflammation-related proteins such as interleukin(IL)-8,vascular cell adhesion molecule(VCAM)-1 and NF-κB in endothelial cells and endothelial cell apoptosis were observed.The relationship between HSP22 and TLR4/NF-κB signaling pathway was investigated under the action of TLR4 inhibitor E5564.Western blot was used to detect the expression of IL-8,VACM-1 and NF-κB proteins,and flow cytometry was used to detect the apoptosis of endothelial cells in each group.Results Compared with the CNT group,the relative expression levels of IL-8,VACM-1 and NF-κB protein in the rhHSP22 group,rhHSP22+ox-LDL group,rhHSP22+E5564 group and rhHSP22+E5564+ox-LDL group were significantly increased,and the differences were sta-tistically significant(P<0.05).Compared with the rhHSP22 group,the relative expression levels of IL-8,VACM-1 and NF-κB protein in the rhHSP22+ox-LDL group were significantly increased,and the differences were statistically significant(P<0.05).Compared with the rhHSP22+ox-LDL group,the relative expression levels of IL-8 and VACM-1 in the rhHSP22+E5564+ox-LDL group were decreased,and the differences were statistically significant(P<0.05).Compared with the CNT group,the apoptosis rate in the rhHSP22 group,rhHSP22+ox-LDL group and rhHSP22+E5564+ox-LDL group was significantly increased,and the differ-ence was statistically significant(P<0.05).Compared with the rhHSP22 group,the apoptosis rate in the rhHSP22+ox-LDL group was increased,and the difference was statistically significant(P<0.05).Compared with the rhHSP22+ox-LDL group,the apoptosis rate in the rhHSP22+E5564+ox-LDL group was de-creased,and the difference was statistically significant(P<0.05).Conclusion In ox-LDL-induced inflamma-tory damage of HCAECs,extracellular HSP22 induces the expression of IL-8,VACM-1 and NF-κB proteins by activating the TLR4/NF-κB signaling pathway,and promotes endothelial cell apoptosis.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective To investigate the renal function recovery and perioperative risk factors for chronic kidney disease in patients after acute Stanford type A aortic dissection (ATAAD) repair. Methods A retrospective study was conducted on patients who underwent ATAAD repair at the Xiamen Cardiovascular Hospital, Xiamen University from 2020 to 2021, and their clinical data were analyzed. Results A total of 255 patients were included, with 200 males and 55 females, and an average age of (52.80±12.46) years. The incidence of acute kidney injury (AKI) after ATAAD repair was 43.9%. Dissection involving the renal artery [OR=2.144, 95%CI (1.234, 3.765), P=0.007], intraoperative urine output [OR=0.761, 95%CI (0.625, 0.911), P=0.004], and intraoperative red blood cell transfusion [OR=1.288, 95%CI (1.088, 1.543), P=0.004] were significantly associated with early AKI after ATAAD repair. Long-term renal function follow-up data were available for 232 patients, among whom 40 (17.2%) patients developed chronic kidney disease (CKD). Independent predictors for CKD included lower body mass index [OR=0.827, 95%CI (0.723, 0.931), P=0.003], preoperative cardiac tamponade [OR=5.344, 95%CI (1.65, 17.958), P=0.005], preoperative renal hypoperfusion syndrome [OR=12.629, 95%CI (5.003, 35.373), P<0.001], postoperative peak serum creatinine time>3 d [OR=7.566, 95%CI (2.799, 22.731), P<0.001], and AKI grade [grade 1: OR=4.418, 95%CI (1.339, 15.361), P=0.016; grade 2: OR=8.345, 95%CI (1.762, 40.499), P=0.007; grade 3: OR=9.463, 95%CI (2.602, 37.693), P<0.001]. Conclusion AKI related to ATAAD repair can recover in the early postoperative period, but both the duration and severity of AKI will affect long-term renal function. In addition, patients' nutritional status, preoperative cardiac tamponade, and renal hypoperfusion syndrome are also independent risk factors for long-term renal dysfunction.

Objective:To evaluate the short-and medium-term therapeutic efficacy of shockwave balloon therapy for TASCⅡ C/D femoropopliteal artery atherosclerosis obliteration.Methods:This retrospective cohort study included 25 patients who received shockwave balloon therapy in five vascular centers from August 2022 to June 2023. All patients were diagnosed with TASC Ⅱ C/D femoropopliteal arteriosclerosis obliterans (13 cases of type C and 12 cases of type D), and underwent intravascular shock wave lithotripsy (IVL) to treat calcified lesions. The immediate effectiveness (residual stenosis<30% and no flow-limiting dissection), safety (whether there were adverse vascular events during the operation) and the rate of salvage stent implantation were recorded. The observation indexes of patients before operation, early postoperative period (immediately after operation or before discharge) and postoperative follow-up period (3, 6, 12 months after operation) were collected. The observation indexes included ankle-brachial index (ABI), Rutherford classification, and minimum lumen diameter (MLD). Repeated measures ANOVA was used to evaluate the changes of observation indexes in the early postoperative and follow-up stages compared with those before operation; Kaplan-Meier survival analysis was used to evaluate the one-stage patency rate at follow-up and the target lesion revascularization rate free from clinical drive.Results:The immediate effectiveness of surgery was 100% in all patients, with no vascular related adverse events occurred, and no remedial stent implantation was performed. The ABI, Rutherford grade and MLD of the patients in the early postoperative period and each follow-up stage were improved compared with those before operation, with statistically significant differences ( P<0.05). Kaplan-Meier survival analysis showed that the primary patency rate at 12 months after surgery was 0.78 (95% CI 0.64-0.84), and the revascularization rate of target lesions free from clinical drive was 0.87 (95% CI 0.85-0.95). Conclusion:Shockwave balloon therapy for complex calcified femoropopliteal artery lesions is safe and reliable, with satisfactory short-and medium-term efficacy.

Objective:To investigate the correlation between remnant cholesterol/high-density lipoprotein cholesterol ratio (RC/HDL-C) and metabolic dysfunction-associated fatty liver disease (MAFLD) in health check-up population.Methods:It was a cross-sectional study. A total of 5 299 subjects who received physical examination in the Health Management Center of Renmin Hospital of Wuhan University from January to December in 2023 and met the admission criteria were selected as the research subjects. The subjects were examined by demography, anthropometry, laboratory tests and liver instantaneous elastography. The Chi-square test, t-test, one-way analysis of variance, Mann-Whitney U test and Kruskal-Wallis H test were used to compare the indexes between the subjects with and without MAFLD. The subjects were divided into 4 groups (Q1-Q4 groups) according to the RC/HDL-C ratio quartiles by quartile method, and the indexes in each group were compared. The receiver operating characteristic (ROC) curves were drawn using MedCalc software and compared to assess the diagnostic efficacy of the RC/HDL-C ratio for MAFLD. Results:With the increase of RC/HDL-C ratio, the detection rate of MAFLD (12.56% vs 43.48%), male proportion (55.68% vs 85.60%), total cholesterol (TC) [(4.63±0.82) vs (5.10±1.06) mmol/L], triglyceride (TG) [0.90(0.71, 1.15) vs 2.58(1.96, 3.50) mmol/L], alanine aminotransferase (ALT) [17.00(13.00, 24.00) vs 26.00(19.00, 38.00) U/L], aspartate aminotransferase (AST) [20.00(17.00, 24.00) vs 23.00(19.00, 29.00) U/L], and controlled attenuation parameter (CAP) [(239.32±40.52) vs (274.60±44.98) dB/m] increased gradually, while high-density lipoprotein cholesterol (HDL-C) [1.40(1.20, 1.64) vs 0.93(0.84, 1.04) μmol/L] decreased gradually (all P<0.05). ROC curves showed that the AUC value of RC/HDL-C ratio was significantly higher in identifying MAFLD when compared with TC, HDL-C, LDL-C, non-HDL-C and RC (AUC=0.676, P<0.05). Conclusions:The RC/HDL-C ratio is positively correlated with the risk of morbidity of MAFLD in health check-up population.

Objective To evaluate the effect of glucocorticoid(GC)treatment on the prognosis of patients with severe viral pneumonia,and to screen for related influencing factors and optimal beneficiary groups,providing reference for clinical medication decisions.Methods Based on the MIMIC-Ⅳ database,eligible patients with severe viral pneumonia were screened and divided into GC group and non GC group.Baseline differences were balanced using propensity score matching(PSM).Kaplan-Meier survival curves were used to analyze the cumulative survival rate of two groups of patients at 30 d,and Cox regression models were used to evaluate the association between GC use and the 30 d mortality risk in patients.Results A total of 518 severe viral pneumonia patients were included,including 43 in the GC group and 475 in the non-GC group.After PSM,there were 43 cases in the GC group and 86 cases in the non-GC group.The Kaplan-Meier survival curves showed that the 30 d cumulative survival rate of patients in the GC group was significantly higher than that in the non-GC group(P＜0.05).The results of multivariate Cox regression analysis showed that GC treatment significantly reduced the 30 d mortality risk[HR=0.35,95％CI(0.154,0.793),P=0.012],especially for patients older than 54 years,receiving mechanical ventilation,and with acute kidney injury.GC use,age＞54 years,and acute kidney injury were independent predictors of patient mortality risk(C-index=0.718 1).Subgroup analysis showed that for specific indications(age＞54 years,mechanical ventilation,no myocardial infarction,no hypertension,no hyperlipidemia,no heart failure,complicated by acute kidney failure),GC use could effectively reduce the 30 d mortality risk.Conclusion GC could effectively improve the prognosis of severe viral pneumonia patients,but individualized patient characteristics and treatment risks need to be considered comprehensively to optimize the medication regimen.
