After the full implementation of Diagnosis-Intervention Packet(DIP)payment,driven by the dual mode of public welfare and economy,disease cost accounting,as a key link,promotes the transformation of hospitals from extensive income-driven development mode to refined operation management.Through literature analysis,it compares the characteristics,advantages and limitations of various methods of disease cost accounting.Combined with the current situation of case hospital cost accounting and the dilemma of disease cost accounting,the parameter distribution method combined with the service unit superposition method is used to realize the medical business cost and medical total cost accounting of the DIP disease in the case hospital.In addition,how to better implement DIP disease cost accounting in county-level public hospitals is discussed and suggested,in order to further improve the same type of hospitals and speed up the application of disease cost accounting results.

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.

Objective To analyze the characteristics of influenza incidence and the changes of innate immune cells among children who visited the pediatric outpatient or emergency department of a hospital in Shanghai from Jan.2019 to Dec.2023,so as to provide references for the prevention of influenza in children.Methods Influenza-like illness(ILI)children who first visited the pediatric outpatient or emergency department of The First Affiliated Hospital of Naval Medical University from Jan.2019 to Dec.2023,and underwent influenza virus antigen or nucleic acid testing were enrolled.Their clinical and laboratory data were collected for retrospective analysis.With a month as the basic monitoring unit,a line chart was used to describe the changes in the number of influenza cases and the positive rate.Then,these cases were assigned to pre-coronavirus disease 2019(COVID-19)group(Jan.2019 to Dec.2019),mid-COVID-19 group(Jan.2020 to Dec.2022),or post-COVID-19 group(Jan.2023 to Dec.2023),and the influenza positive rates among these groups were compared.To further observe the changes of the innate immune cells of children with influenza A after non-pharmacological intervention(NPI)measures,considering the development characteristics of children's white blood cells,children with influenza A were assigned to 2 subgroups according to age:0-6 years or 7-16 years.Within each subgroup,they were assigned to pre-NPI group or post-NPI group according to time.A ratio of 1∶1 matching was carried out according to gender and age using propensity score matching,and the blood routine parameters were compared between the 2 groups.Results A total of 41 028 ILI children were enrolled.During the COVID-19 period from Jan.2020 to Dec.2022,the influenza positive rates decreased significantly(P＜0.001),and almost no influenza virus was detected.The peak of influenza reappeared in Mar.2023,with a lag in the peak period,but higher than previous years'peak,and the speed of reaching the peak was faster.In each subgroup,the white blood cell count and lymphocyte ratio of children with influenza A in the post-NPI group were lower than those in the pre-NPI group(all P＜0.001),and the monocyte ratio was higher than that in the pre-NPI group(both P＜0.001).Conclusion The implementation of NPI measures during COVID-19 leads to disruption of influenza transmission route and changes in the epidemic trend of influenza.The influenza virus causes serious public health problems after COVID-19 period,and children with influenza A experience more serious immune response.It is recommended to strengthen the vaccination of influenza vaccine before the flu season.

Objective To explore the palliative care needs of peritoneal dialysis patients and their care-givers,providine a scientific basis for the targeted implementation of palliative care intervention programs.Methods A semi-structured in-depth interview was conducted on 14 patients and 6 caregivers at a peritoneal dialysis center in a third-class hospital in Beijing.We used the Colaizzi seven-step data analysis method and the phenomenological method of qualitative research to analyze the data and refine the theme.Results Through the analysis,5 theme groups were summarized,including the need to alleviate physiological and psychological symptoms,the need for family support and help,the need for social help,the lack of understanding of pallia-tive care,and the lack of scientific view of death.Conclusions Peritoneal dialysis patients and their caregiv-ers have a strong need for palliative care.Medical staff should fully respect the uniqueness of peritoneal dialysis patients and implement targeted palliative care interventions based on their needs and preferences,so as to ef-fectively improve their quality of life.

Protrusive facial deformities, characterized by the forward displacement of the teeth and/or jaws beyond the normal range, affect a considerable portion of the population. The manifestations and morphological mechanisms of protrusive facial deformities are complex and diverse, requiring orthodontists to possess a high level of theoretical knowledge and practical experience in the relevant orthodontic field. To further optimize the correction of protrusive facial deformities, this consensus proposes that the morphological mechanisms and diagnosis of protrusive facial deformities should be analyzed and judged from multiple dimensions and factors to accurately formulate treatment plans. It emphasizes the use of orthodontic strategies, including jaw growth modification, tooth extraction or non-extraction for anterior teeth retraction, and maxillofacial vertical control. These strategies aim to reduce anterior teeth and lip protrusion, increase chin prominence, harmonize nasolabial and chin-lip relationships, and improve the facial profile of patients with protrusive facial deformities. For severe skeletal protrusive facial deformities, orthodontic-orthognathic combined treatment may be suggested. This consensus summarizes the theoretical knowledge and clinical experience of numerous renowned oral experts nationwide, offering reference strategies for the correction of protrusive facial deformities.

Objective:To investigate the magnetic resonance imaging (MRI) features of pediatric and adolescent mediastinal T-lymphoblastic lymphoma (T-LBL) and to evaluate their predictive value for early treatment response.Methods:A retrospective, multicenter case series study was conducted on 49 pediatric and adolescent patients diagnosed with mediastinal T-LBL between September 2020 and May 2024 at the Fifth Affiliated Hospital of Zhengzhou University, Beijing Gaobo Boren Hospital, and Henan Cancer Hospital.All patients underwent chest MRI, including conventional MRI sequences and diffusion-weighted imaging.Tumor imaging characteristics were analyzed, and quantitative parameters such as minimum apparent diffusion coefficient (ADCmin), maximum ADC (ADCmax), and mean ADC (ADCmean) were measured.Treatment response was evaluated 15 days post-treatment.The patients were divided into a response group (complete or partial response, 26 cases) and a non-response group (progressive disease or minor response, 23 cases).The relationship between MRI features and treatment response was analyzed.The intraclass correlation coefficient was used to assess inter-reader agreement, and independent sample t-tests and chi-square tests were employed to compare differences between groups.Receiver operating characteristic (ROC) curve analysis was conducted to evaluate the predictive performance of imaging parameters. Results:Significant differences were observed between the response and non-response groups in ADC values [ADCmin (0.80±0.41)×10 -3 mm 2/s vs.(1.23±0.70)×10 -3 mm 2/s, ADCmax (1.14±0.48)×10 -3 mm 2/s vs.(1.92±0.77)×10 -3 mm 2/s, ADCmean (0.98±0.42)×10 -3 mm 2/s vs.(1.56±0.74)×10 -3 mm 2/s] and the maximum tumor diameter was [(11.92±3.61) cm vs.(8.17±2.46) cm] (all P<0.05).ROC curve analysis showed that ADCmax had the highest predictive efficiency for treatment response, with an area under the curve (AUC) of 0.853 (95% CI: 0.790-0.910), sensitivity of 92.3%, and specificity of 65.2%.The AUC for the maximum tumor diameter was 0.814, demonstrating its excellent predictive performance. Conclusions:MRI features, particularly ADC values and the maximum tumor diameter, can effectively predict treatment response in pediatric and adolescent mediastinal T-LBL.

Objective: To investigate the role mechanism of doublecortin(DCX) in glioma and screen DCX overexpression-related differentially expressed genes, so as to provide new targets for glioma targeted therapy. Methods: Using rat glioma C6 cells as the target cells, LV-DCX-EGFP, LV-Cas9-Puro, and LV-Ctrl-EGFP lentiviruses were constructed. DCX overexpressing and control C6 cell lines were established through Cas9 dual-vector system transfection and screening. Transcriptome sequencing was used to obtain the differentially expressed gene profiles. iDEP and DESeq2 were applied to screen differentially expressed genes with the threshold of |Log_2FC|>2 and P0.7, indicating good diagnostic value. RT-qPCR validation showed that the mRNA expression levels of some upregulated genes(POU2F3, LPAR6, SREBF1) significantly increased ( P < 0. 001) , while the mRNA expression levels of some downregulated genes (UBB , ACTB , UBE2I) also significantly increased (P < 0. 001) , which might be relat⁃ed to transcriptional and post⁃transcriptional regulation. Conclusion Differentially expressed genes and their regu⁃latory networks related to DCX overexpression in glioma are successfully screened , providing a theoretical basis for revealing the role mechanism of DCX in glioma development and laying a foundation for the development of potential therapeutic strategies.

Objective:To evaluate the effect of an opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine on early postoperative recovery in patients undergoing laparoscopic radical resection of colon cancer.Methods:This study was a randomized controlled trial. From January 2023 to July 2024, 72 patients of either sex, aged 45-65 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective laparoscopic radical resection of colon cancer with general anesthesia at Yichang Central People′s Hospital, were divided into 2 groups ( n=36 each) using a random number table method: control group (group C) and opioid-sparing anesthesia strategy group (group D). Anesthesia was induced with sufentanil and propofol and maintained with propofol and remifentanil in group C. In group D, ultrasound-guided quadratus lumborum block was performed before the start of anesthesia, and anesthesia was induced with esketamine, propofol and lidocaine and maintained with esketamine, propofol, low-dose remifentanil, lidocaine and magnesium sulfate. Patient-controlled intravenous analgesia was carried out at the end of surgery until 48 h postoperatively, using dezocine for rescue analgesia. The Quality of Recovery-15 scores were assessed and recorded at 1 day before operation and 1, 3 and 7 days after operation. Ramsay sedation scores were recorded at 2, 6, 12, 24 and 48 h after surgery. The effective pressing times of patient-controlled analgesia and requirement for rescue analgesia were recorded within 24 h after surgery and during the 24-48 h postoperative period. The intraoperative consumption of opioid, emergence time, duration of postanesthesia care unit stay, time to first flatus, first ambulation time and length of postoperative hospital stay were also recorded. The postoperative complications were recorded during hospital stay and assessed with the Clavien-Dindo classification. Results:Compared with group C, the Quality of Recovery-15 scores were significantly increased at each time point after operation, Ramsay sedation scores were increased at 2, 6 and 12 h after operation, the effective pressing times of patient-controlled analgesia and rate of rescue analgesia were decreased in each postoperative period, the intraoperative consumption of remifentanil was reduced, the time to first flatus, first ambulation time and length of postoperative hospital stay were shortened, the incidence of nausea and vomiting was decreased ( P<0.05), and no significant change was found in the emergence time or duration of postanesthesia care unit stay in group D ( P>0.05). Conclusions:The opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine can raise the quality of early postoperative recovery in the patients undergoing laparoscopic radical resection of colon cancer.
