Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Purpose To evaluate the diagnostic value of three-dimensional amide proton transfer weighted imaging(APTWI)in distinguishing benign from malignant bone tumors and the diagnostic efficacy of APTWI combined with diffusion-weighted imaging(DWI).Materials and Methods Sixty-nine patients with pelvic and lower extremity bone tumors,confirmed by puncture or surgical pathology at the First Affiliated Hospital of Zhengzhou University,were prospectively collected from April 2022 to July 2023.On the relevant parameter maps of APTWI and DWI,the asymmetric magnetization transfer rate at a chemical shift of 3.5 ppm[MTRasym(3.5 ppm)]and apparent diffusion coefficient(ADC)values corresponding to the lesions were measured,respectively.Comparative analysis of differences in each parameter was conducted,and the diagnostic efficacy of these parameters alone and in combination was compared.Results Among 69 bone tumor,24 were benign cases and 45 malignant cases.MTRasym(3.5 ppm)of malignant bone tumors was higher than that of benign tumors[(2.974±0.630)%vs.(2.215±0.963)%],while ADC values of malignant bone tumors were lower than those of benign tumors[(1.143±0.406)×10-3 s/mm2 vs.(1.757±0.449)×10-3 s/mm2],with significant differences between the two groups(t=3.532,-5.645;P<0.001).Receiver operating characteristic curve showed that MTRasym(3.5 ppm),ADC values,and their combination exhibited good performance in the differential diagnosis of benign and malignant bone tumors,with the area under the curve being 0.765,0.841 and 0.874,respectively.There were no statistically significant differences in the area under the curve between the combined APTWI-DWI and either APTWI or DWI alone in diagnosing benign and malignant bone tumors(combined vs.APTWI:Z=1.873,P=0.064;combined vs.DWI:Z=1.333,P=0.167).The diagnostic specificity of combined APTWI-DWI was significantly higher than that of APTWI alone(96%vs.56%,P=0.001),but there was no statistically significant difference compared with DWI alone(96%vs.80%,P=0.189).Conclusion APTWI and DWI,either alone or in combination,could serve as effective imaging indicators for distinguishing benign from malignant bone tumors.The combination of APTWI and DWI shows a trend of achieving higher diagnostic efficacy and diagnostic specificity in differentiating benign from malignant bone tumors,thus holding potential clinical application value.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

OBJECTIVE: To explore clinical efficacy of membrane-induced technique combined with gastrocnemius muscle flap transposition in treating traumatic osteomyelitis of the upper tibia. METHODS: A retrospective analysis was conducted on 7 patients with traumatic osteomyelitis of the upper tibia who were treated with membrane-induced technique combined with gastrocnemius muscle flap transposition from January 2022 to December 2023. Among them, there were 4 males and 3 females; aged from 29 to 57 years old; 4 patients were treated after open fracture, 2 patients were treated after closed fracture, and 1 patient was treated after scalding; the courses of disease ranges from 2 weeks to 8 years; sinus tracts were present in all patients, and the lesion range of the tibia ranged from 5 to 9 cm. The results of deep tissue bacterial culture showed that 2 patients were negative, 3 patients were staphylococcus aureus, 1 patient was methicillin-resistant staphylococcus aureus, and 1 patient was pseudomonas aeruginosa and 1 patient was klebsiella pneumoniae. After debridement, the range of bone defect ranged from 8 to 12 cm, and the cortical defect accounted for approximately 30% of the circumference. The area of soft tissue defect ranged from 8.0 cm×2.0 cm to 10.0 cm×6.0 cm. At the first stage, vancomycin-loaded/meropenem/gentamicin-loaded bone cement was implanted. The gastrocnemius muscle flap was repositioned to cover the wound surface and free skin grafting was performed. After an interval of 7 to 10 weeks, the stageⅡsurgery was performed to remove bone cement. Autologous iliac bone mixed with vancomycin/gentamicin and calcium sulfate artificial bone was transplanted, and the wound was sutured. One patient retained the original internal plants, one patient removed the internal plants and replaced them with steel plate external fixation, one patient replaced the internal plants and added steel plate external fixation, and three patients were simply fixed with steel plate external fixation. One year after operation, the recovery of knee joint and ankle joint functions was evaluated by using Hospital for Special Surgery (HSS) knee joint score and Kofoed ankle joint function score respectively. RESULTS: All patients had their wounds closed simultaneously with bone cement implantation and healed well. All patients were followed up for 12 to 17 months after operation, and satisfactory bone healing was achieved at 6 months after stageⅡsurgery. Twelve months after operation, all patients had good bone healing without obvious limping was observed when walking. At 12 months after operation HSS knee joint score ranged from 93 to 100 points, and Kofoed ankle function score ranged from 96 to 100 points. CONCLUSION For traumatic osteomyelitis of the upper tibia, a staged treatment plan combining membrane-induced technique and gastrocnemius flap transposition on the basis of thorough debridement could safely cover the wound surface, effectively control bone infection and achieve satisfactory bone healing, without adverse effects on limb function.

PURPOSE: We carried out the study aiming to explore and analyze the risk factors, the distribution of pathogenic bacteria, and their antibiotic-resistance characteristics influencing the occurrence of surgical site infection (SSI), to provide valuable assistance for reducing the incidence of SSI after traumatic fracture surgery. METHODS: A retrospective case-control study enrolling 3978 participants from January 2015 to December 2019 receiving surgical treatment for traumatic fractures was conducted at Tangdu Hospital of Air Force Medical University. Baseline data, demographic characteristics, lifestyles, variables related to surgical treatment, and pathogen culture were harvested and analyzed. Univariate analyses and multivariate logistic regression analyses were used to reveal the independent risk factors of SSI. A bacterial distribution histogram and drug-sensitive heat map were drawn to describe the pathogenic characteristics. RESULTS: Included 3978 patients 138 of them developed SSI with an incidence rate of 3.47% postoperatively. By logistic regression analysis, we found that variables such as gender (males) (odds ratio (OR) = 2.012, 95% confidence interval (CI): 1.235 - 3.278, p = 0.005), diabetes mellitus (OR = 5.848, 95% CI: 3.513 - 9.736, p < 0.001), hypoproteinemia (OR = 3.400, 95% CI: 1.280 - 9.031, p = 0.014), underlying disease (OR = 5.398, 95% CI: 2.343 - 12.438, p < 0.001), hormonotherapy (OR = 11.718, 95% CI: 6.269 - 21.903, p < 0.001), open fracture (OR = 29.377, 95% CI: 9.944 - 86.784, p < 0.001), and intraoperative transfusion (OR = 2.664, 95% CI: 1.572 - 4.515, p < 0.001) were independent risk factors for SSI, while, aged over 59 years (OR = 0.132, 95% CI: 0.059 - 0.296, p < 0.001), prophylactic antibiotics use (OR = 0.082, 95% CI: 0.042 - 0.164, p < 0.001) and vacuum sealing drainage use (OR = 0.036, 95% CI: 0.010 - 0.129, p < 0.001) were protective factors. Pathogens results showed that 301 strains of 38 species of bacteria were harvested, among which 178 (59.1%) strains were Gram-positive bacteria, and 123 (40.9%) strains were Gram-negative bacteria. Staphylococcus aureus (108, 60.7%) and Enterobacter cloacae (38, 30.9%) accounted for the largest proportion. The susceptibility of Gram-positive bacteria to Vancomycin and Linezolid was almost 100%. The susceptibility of Gram-negative bacteria to Imipenem, Amikacin, and Meropenem exceeded 73%. CONCLUSION Orthopedic surgeons need to develop appropriate surgical plans based on the risk factors and protective factors associated with postoperative SSI to reduce its occurrence. Meanwhile, it is recommended to strengthen blood glucose control in the early stage of admission and for surgeons to be cautious and scientific when choosing antibiotic therapy in clinical practice.

Purpose To evaluate the diagnostic value of three-dimensional amide proton transfer weighted imaging(APTWI)in distinguishing benign from malignant bone tumors and the diagnostic efficacy of APTWI combined with diffusion-weighted imaging(DWI).Materials and Methods Sixty-nine patients with pelvic and lower extremity bone tumors,confirmed by puncture or surgical pathology at the First Affiliated Hospital of Zhengzhou University,were prospectively collected from April 2022 to July 2023.On the relevant parameter maps of APTWI and DWI,the asymmetric magnetization transfer rate at a chemical shift of 3.5 ppm[MTRasym(3.5 ppm)]and apparent diffusion coefficient(ADC)values corresponding to the lesions were measured,respectively.Comparative analysis of differences in each parameter was conducted,and the diagnostic efficacy of these parameters alone and in combination was compared.Results Among 69 bone tumor,24 were benign cases and 45 malignant cases.MTRasym(3.5 ppm)of malignant bone tumors was higher than that of benign tumors[(2.974±0.630)%vs.(2.215±0.963)%],while ADC values of malignant bone tumors were lower than those of benign tumors[(1.143±0.406)×10-3 s/mm2 vs.(1.757±0.449)×10-3 s/mm2],with significant differences between the two groups(t=3.532,-5.645;P<0.001).Receiver operating characteristic curve showed that MTRasym(3.5 ppm),ADC values,and their combination exhibited good performance in the differential diagnosis of benign and malignant bone tumors,with the area under the curve being 0.765,0.841 and 0.874,respectively.There were no statistically significant differences in the area under the curve between the combined APTWI-DWI and either APTWI or DWI alone in diagnosing benign and malignant bone tumors(combined vs.APTWI:Z=1.873,P=0.064;combined vs.DWI:Z=1.333,P=0.167).The diagnostic specificity of combined APTWI-DWI was significantly higher than that of APTWI alone(96%vs.56%,P=0.001),but there was no statistically significant difference compared with DWI alone(96%vs.80%,P=0.189).Conclusion APTWI and DWI,either alone or in combination,could serve as effective imaging indicators for distinguishing benign from malignant bone tumors.The combination of APTWI and DWI shows a trend of achieving higher diagnostic efficacy and diagnostic specificity in differentiating benign from malignant bone tumors,thus holding potential clinical application value.

Objective To investigate the expression and clinical significance of microRNA-148a-3p (miR-148a-3p) in lung adenocarcinoma and analyze the effect and mechanism of miR-148a-3p on radiotherapy sensitivity of lung adenocarcinoma cells by targeting the protein core 1β13-galactosyltransferase 1(C1GALT1). Methods Seventy-six patients' tumor tissues from lung adenocarcinoma tissue microarrays and lung adenocarcinoma A549 cell line were selected for the study. The miR-148a-3p in situ hybridizations (ISH) and C1GALT1 immunohistochemical staining were performed on the tissue microarrays to analyze the correlations of miR-148a-3p expression with clinical pathology, prognosis and C1GALT1 expression in the tumor tissues of the 76 patients with lung adenocarcinoma. A549 cells were transfected with miR-148a-3p overexpression plasmid by using cell transfection technique; the clone formation assay was used to detect the sensitivity of the transfected cells for radiotherapy after receiving 2 Gy radiotherapy; the protein expression level of cellular C1GALT1 was detected by western blot; the targeted regulatory relationship between miR-148a-3p and C1GALT1 was verified by dual-luciferase reporter gene experiment; the mechanism of miR-148a-3p regulating the sensitivity of A549 cells to radiotherapy was analyzed by co-transfection technique. Results Low expression of miR-148a-3p in 76 cases of lung adenocarcinoma tissues was significantly associated with lymph node metastasis (P=0.012); the prognosis of patients with high expression of miR-148a-3p was significantly better than that of patients with low expression of miR-148a-3p (P=0.005); there was a significant negative correlation between the expression of miR-148a-3p and C1GALT1 in lung adenocarcinoma tissues (P=0.023). Multivariate analysis showed that low expression of miR-148a-3p, T staging and lymph node metastasis were the independent risk factors for prognosis. Clone formation experiment showed that the number of clone formation in the miR-148a-3p overexpression group was significantly lower than that in the control group (P < 0.001); western blot result showed that overexpression of miR-148a-3p was able to significantly down-regulate the level of C1GALT1 protein in cells (P < 0.001). Dual luciferase reporter gene experiment showed that miR-148a-3p was able to regulate the expression of C1GALT1 by binding to the 3'UTR of C1GALT1. Functional rescue experiment showed that C1GALT1 could partially offset the radiosensitization effect of miR-148a-3p. Conclusion Low expression of miR-148a-3p in lung adenocarcinoma is significantly associated with lymph node metastasis, high expression of C1GALT1 and poor prognosis, and miR-148a-3p can enhance the radiosensitivity of lung adenocarcinoma cells by negatively regulating the expression of C1GALT1.

INTRODUCTION: This systematic review and meta-analysis aimed to evaluate the effectiveness and safety of adjunct systemic corticosteroid therapy in patients admitted to the intensive care unit (ICU) with bacterial community-acquired pneumonia (CAP). METHOD: We searched MEDLINE, Embase and the Cochrane Library to identify randomised controlled trials (RCTs) published from the databases' inception to February 2024. All RCTs evaluating the effect of systemic corticosteroids on mortality, compared to standard of care among adult bacterial CAP patients admitted to ICU were included. Bayesian meta-analysis was conducted in line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Independent authors reviewed each study for eligibility, extracted data and assessed risk of bias in duplicate, with discrepancies referred to senior reviewers. RESULTS: A total of 6 RCTs comprising 1585 patients were included for analysis. In ICU patients with severe CAP who were treated with corticosteroids, there was no significant reduction in hospital mortality (risk ratio [RR] 0.70, 95% confidence interval [CI] 0.39-1.14, certainty of evidence: ⊕⊕⊝⊝ low) or all-cause mortality (RR 0.68, 95% CI 0.34-1.22, ⊕⊕⊝⊝ low) compared with placebo. The use of corticosteroids showed a significant reduction in mechanical ventilation post-intervention (RR 0.58, 95% CI 0.37-0.86, ⊕⊕⊕⊕ high) compared with placebo. In a subgroup analysis of patients treated with hydrocortisone, hospital mortality was significantly reduced (RR 0.45, 95% CI 0.20-0.88, ⊕⊕⊝⊝ low) compared with placebo. There was no significant increase in gastrointestinal bleeding, secondary infections or hyperglycaemia in patients treated with corticosteroids. CONCLUSION Corticosteroids significantly reduced mechanical ventilation requirements, and hydrocor-tisone significantly reduced hospital mortality. Further work is required to determine whether other corticosteroids reduce mortality among ICU patients with CAP.
