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 observe the effect of rehabilitation robot training on abdominal muscles thickness and balance ability in children with hemiplegia. MethodsFrom October, 2024 to December, 2025, 58 children with hemiplegia were admitted to Beijing Bo'ai Hospital and randomly divided into control group (n = 29) and experimental group (n = 29). Both groups received conventional rehabilitation treatment, and the experimental group received rehabilitation robot training in addition, for four weeks. The thickness of bilateral external oblique, internal oblique and transversus abdominis, Berg Balance Scale (BBS) score, the time of Timed Up and Go Test (TUGT), the center of pressure (COP) ellipse area, and self-selected walking speed (SWS) and maximum walking speed (MWS) of 10-meter walk test were compared before and after training. ResultsThree cases dropped out in each group. After training, the thickness of the external oblique, internal oblique and transverse abdominis on the hemiplegic side increased significantly in the experimental group (|t| > 7.280, P < 0.001, Cohen's d = 1.43~2.01), and was better in the experimental group than in the control group (|t| > 2.895, P < 0.01, Cohen's d = 0.80~1.60); the BBS score increased in both groups (|t| > 6.667, P < 0.001, Cohen's d = 1.30~4.06), and was better in the experimental group than in the control group (t = -2.721, P < 0.01, Cohen's d = 0.75). The time of TUGT decreased in both groups (t > 5.790, P < 0.001, Cohen's d = 1.14~2.68), and was better in the experimental group than in the control group (t = 2.290, P < 0.05, Cohen's d = 0.63). The SWS and MWS increased in both groups (|Z| > 2.910, P < 0.01, r = 0.40~0.68), and were better in the experimental group than in the control group (|Z| > 2.912, P < 0.05, r = 0.40~0.45), and the differences remained significant after correction. ConclusionRehabilitation robot training can improve the thickness of external oblique, the internal oblique and transversus abdominis muscles on the hemiplegic side in children with hemiplegia, and improve their balance and walking functions.

Objective To explore the relationship between PANoptosis and hepatic ischemia-reperfusion injury (HIRI), and to screen the key genes of PANoptosis in HIRI. Methods PANoptosis-related differentially expressed genes (PDG) were obtained through the Gene Expression Omnibus database and GeneCards database. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways related to PDG. A protein-protein interaction network was constructed. Key genes were selected, and their diagnostic value was assessed and validated in the HIRI mice. Immune cell infiltration analysis was performed based on the cell-type identification by estimating relative subsets of RNA transcripts. Results A total of 16 PDG were identified. GO analysis showed that PDG were closely related to cellular metabolism. KEGG analysis indicated that PDG were mainly enriched in cellular death pathways such as apoptosis and immune-related signaling pathways such as the tumor necrosis factor signaling pathway. GSEA results showed that key genes were mainly enriched in immune-related signaling pathways such as the mitogen-activated protein kinase (MAPK) signaling pathway. Two key genes, DFFB and TNFSF10, were identified with high accuracy in diagnosing HIRI, with areas under the curve of 0.964 and 1.000, respectively. Immune infiltration analysis showed that the control group had more infiltration of resting natural killer cells, M2 macrophages, etc., while the HIRI group had more infiltration of M0 macrophages, neutrophils, and naive B cells. Real-time quantitative polymerase chain reaction results showed that compared with the Sham group, the relative expression of DFFB messenger RNA in liver tissue of HIRI group mice increased, and the relative expression of TNFSF10 messenger RNA decreased. Cibersort analysis showed that the infiltration abundance of naive B cells was positively correlated with DFFB expression (r=0.70, P=0.035), and the infiltration abundance of M2 macrophages was positively correlated with TNFSF10 expression (r=0.68, P=0.045). Conclusions PANoptosis-related genes DFFB and TNFSF10 may be potential biomarkers and therapeutic targets for HIRI.

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 explore the effect of Lokomat robotic-assisted gait training on lower limb motor function in children with hemiplegia.Methods From October,2023 to January,2025,a total of 52 children with hemiplegia admitted to Beijing Bo'ai Hospital were randomly divided into control group(n=26)and observation group(n=26).Both groups received conven-tional rehabilitation therapy,while the observation group additionally received Lokomat robotic-assisted gait training,for four weeks.Before and after intervention,the self-selected walking speed(SWS)and maximum walking speed(MWS)of 10-meter Walk Test,6-minute walking distance(6MWD),Physiological Cost Index(PCI),as well as gait line length asymmetry ratio,single support line asymmetry ratio,stance phase asymmetry ratio and step length ratio were compared.Results After intervention,SWS,MWS and 6MWD improved in both groups(|Z|>2.910,P<0.01),and were better in the the observation group than in the control group(|Z|>2.069,P<0.05);PCI significantly decreased in both groups(|Z|>4.458,P<0.001),and was lower in the observation group than in the control group(Z=-2.435,P<0.05);the gait line length asymmetry ratio,single support line asymmetry ratio and stance phase asymmetry ratio improved in both groups(Z=3.398,|t|>2.211,P<0.05),and were better in the observation group than in the control group(Z=2.802,|t|>2.107,P<0.05).Conclusion Lokomat robotic-assisted gait training can effectively improve walking speed and endurance in children with hemiplegia,reduce energy expenditure,enhance walking efficiency,and promote gait symmetry,thereby fa-cilitating symmetrical gait patterns.

Objective To investigate the potential role of plasma adiponectin concentration in predicting the response of patients with depression to electroconvulsive therapy(ECT).Methods This study enrolled depressive patients scheduled for ECT at the First Hospital of Shanxi Medical University between January 2022 and March 2024.Patients were categorized as either ECT responders(>50%reduction)or non-responders(≤50%reduction)based on post-ECT reduction rate of the 24-item Hamilton depression scale(HAMD)scores from baseline.Plasma adiponectin levels were measured in all patients before their first ECT treatment.To identify predictors of ECT response in patients with depression,the predictive value of plasma adiponectin was evaluated using receiver operating characteristic(ROC)curve analysis.Results A total of 80 patients with depression were enrolled including 44 in the ECT-responsive group and 36 in the non-responsive group.The plasma adiponectin level was significantly higher in the responsive group than in the non-responsive group[5.67(3.64,10.55)μg/mL vs.4.01(2.59,5.04)μg/mL,P=0.002].Pearson correlation analysis revealed a significant positive correlation between plasma adiponectin levels and the HAMD reduction rate(r=0.300,P=0.007).Multivariate logistic regression analysis showed that plasma adiponectin was independently associated with the response to ECT in patients with depression(OR=1.218,95%CI:1.009-1.470,P=0.040).Furthermore,ROC curve analysis demonstrated that the area under the curve(AUC)for adiponectin in predicting ECT response was 0.748(95%CI:0.583-0.813).Conclusion Pretreatment plasma adiponectin may serve as a potential biomarker for predicting response to ECT in patients with depression.

Objective To discuss the efficacy and safety of AcoStream mechanical thrombectomy(AMT)system in treating high risk acute pulmonary embolism(APE),and to analyze the risk factors associated with postoperative recurrence of pulmonary embolism(PE).Methods A total of 137 patients with APE,who were admitted to Bingzhou Medical University Hospital Yantai Affiliated hospital from January 2018 to April 2023,were collected.The patients were divided into AMT group(receiving AMT treatment,n=76)and catheter-directed thrombolysis group(CDT group,n=61).The preoperative risk,surgical core indicators,perioperative and follow-up results,and incidence of adverse events were compared between the two groups.One month after treatment,the risk factors for PE recurrence in the AMT group were analyzed.Results Compared with the CDT group,in the AMT group the preoperative risk stratification of pulmonary embolism was higher,the patients were older,the cardiac function grade was higher,the intraoperative used urokinase dose was less,and the postoperative hospital stay was shorter;the differences in the above indexes between the two groups were statistically significant(all P＜0.05).During follow-up period of one month,the difference in the recurrence of pulmonary embolism between the two groups was statistically significant(P=0.026).Logistic regression analysis revealed that pre-operative NT-proBNP was the risk factor for PE recurrence at one month after AMT treatment(OR=1.001,95％CI:1.000-1.001).Conclusion AMT technique carries high efficacy for removing thrombus in different pulmonary artery segments,which is suitable for the treatment of APE.While reducing the bleeding amount,AMT technique will not increase the time spent for operation,besides,it has excellent advantages in improving the right heart function and in ensuring clinical safety.

Objective To investigate the effects of physical activity and disease burden on self-ef-ficacy and quality of life in patients with inflammatory bowel disease(IBD).Methods A total of 312 IBD patients were selected by convenience sampling method.General information of patients was col-lected.Self-efficacy[Chronic Disease Management Self-Efficacy Scale(CDM-SES)],physical activi-ty[International Physical Activity Questionnaire-Short Form(IPAQ-SF)],disease burden[Inflamma-tory Bowel Diseases Disk(IBD-disk)Scale]and quality of life[Inflammatory Bowel Disease Ques-tionnaire(IBDQ)]were assessed in IBD patients.The chain-mediating effects of physical activity and disease burden on self-efficacy and quality of life in IBD patients were analyzed.Results There were statistically significant differences in self-efficacy of IBD patients with different ages,body mass index(BMI),places of residence,marital status,educational background and disease stages(P＜0.05);there were statistically significant differences in physical activity among IBD patients with different gen-der,age,place of residence,marital status,education background,disease stage and whether to use biological agents(P＜0.05);there were statistically significant differences in the disease burden of IBD patients with different BMI,place of residence,marital status,education background,payment method and disease stage(P＜0.05);there were statistically significant differences in the quality of life of IBD patients with different ages,places of residence,marital status,education levels,pay-ment methods,disease stages and whether to use biological agents(P＜0.05).The quality of life of IBD patients was positively correlated with self-efficacy and physical activity(r=0.605,0.482,P＜0.01),and negatively correlated with disease burden and disease stage(r=-0.550,-0.362,P＜0.01).Physical activity and disease burden partially mediated between self-efficacy and quality of life in IBD patients.Conclusion IBD patients exhibited moderate levels of self-effi-cacy,low levels of physical activity,and high disease burdens.Clinical healthcare professionals should actively take measures to improve patients'self-efficacy and physical activity levels to reduce disease burden.

Objective To analyze the effect of Callicarpa nudiflora on wound healing and phos-phatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/AKT/mTOR)path-way by regulating M2 macrophage polarization in rats with diabetic foot ulcer.Methods A total of 40 rats were selected,with 10 rats in control group(topical application of saline),and the remaining 30 were used to establish rat model of diabetic foot ulcer.Ultimately,27 rats were successfully mod-eled and divided into model group(topical application of saline),Callicarpa nudiflora group(topi-cal application of Callicarpa nudiflora),and Callicarpa nudiflora combined with inhibitor group(topical application of Callicarpa nudiflora combined with CD206 inhibitor,a marker protein of M2 macrophages),with 9 rats in each group.The wound healing rate,levels of basic fibroblast growth factor(bFGF)and vascular endothelial growth factor(VEGF),relative expression levels of induc-ible nitric oxide synthase(iNOS),CD16/32,CD206,PI3K,AKT and mTOR as well as mRNA ex-pression levels of PI3K,AKT and mTOR were compared among groups.Results On the 3rd,7th and 14th days after intervention,compared with the control group,the wound healing rate,VEGF,bFGF,relative expression level of CD206,relative expression of PI3K,AKT and mTOR at mRNA and protein levels were significantly decreased while the relative expression levels of iNOS and CD16/32 were significantly increased in all other groups(P＜0.05);compared with the model group,the Callicarpa nudiflora group and the Callicarpa nudiflora combined with inhibitor group showed significant increased wound healing rate,VEGF,bFGF,relative expression level of CD206,and relative expression of PI3K,AKT and mTOR at mRNA and protein levels,and significant de-creased relative expression levels of iNOS and CD16/32(P＜0.05);compared with the Callicarpa nudiflora group,the Callicarpa nudiflora combined with inhibitor group showed significant decreased wound healing rate,VEGF,bFGF,relative expression level of CD206,and relative expression of PI3K,AKT and mTOR at mRNA and protein levels,and significant increased relative expression levels of iNOS and CD16/32(P＜0.05).Conclusion Callicarpa nudiflora can promote M2 mac-rophage polarization,increase wound healing rate and levels of VEGF and bFGF in rats with diabetic foot ulcer,and activate the PI3K/AKT/mTOR signaling pathway.

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.
