Objective This study aimed to develop and empirically evaluate a sarcopenia management program for lung transplant candidates based on the Transtheoretical Model(TTM).The objective was to improve preopera-tive muscle condition and enhance patients' tolerance to lung transplantation.Methods Using the TTM as the the-oretical framework,the sarcopenia management program was developed through a literature review and 2 rounds of expert consultations.A convenience sampling method was employed to recruit inpatients from the lung transplant department of a tertiary hospital in Zhejiang Province between January 2022 and January 2024.Patients admitted between February 2023 and January 2024 were assigned to an intervention group,while those admitted between January 2022 and January 2023 were allocated to a control group.The intervention group received an 8-week sar-copenia management program based on the TTM in addition to standard prehabilitation care,whereas the control group received only standard prehabilitation care.Outcome measurements included pre-and post-intervention com-parisons of the modified Strength,Assistance with Walking,Rise from a Chair,Climb Stairs,Falls,and Calf Circum-ference(SARC-CalF)score,handgrip strength,6-minute walking distance(6MWD),and upper arm circumference,as well as their respective changes before and after the intervention.Additionally,stage-based behavioral change as-sessment and adverse event incidence were compared between the 2 groups.Results A total of 8 patients from the intervention group and 9 from the control group dropped out,resulting in a final sample of 32 patients in the intervention group and 31 in the control group.Compared to the control group,the intervention group demonstrated significantly greater improvements in SARC-CalF scores,handgrip strength,6MWD,and upper arm circumference(P＜0.05).After the intervention,the intervention group had a statistically significant difference in behavioral stage tran-sition compared to the control group(P＜0.05).During the intervention process,neither group experienced any ad-verse events.Conclusion The sarcopenia management program based on the TTM effectively improved patient ad-herence,enhanced preoperative muscle condition,and demonstrated potential benefits in improving physical function and nutritional status.

Objective:To explore the independent risk factors for chemoresistance during gemcitabine plus cisplatin (GC) adjuvant chemotherapy in patients with locally advanced bladder cancer after radical cystectomy and to construct a related predictive model.Methods:The clinical data of 228 patients with locally advanced bladder cancer who received GC chemotherapy after radical cystectomy at Beijing Friendship Hospital, Capital Medical University, from January 2013 to June 2024 were retrospectively analyzed. Among them, 184 were males, and 44 were females, with an average age of (68.8±10.6)years and an average body mass index (BMI) of (24.2±3.6)kg/m 2. According to tumor progression during chemotherapy, patients were divided into a chemotherapy-resistant(CR) group ( n=59) and a non-chemotherapy-resistant(NCR) group ( n=169). Independent sample t-test, chi-square test, and non-parametric test were used to compare general clinical characteristics and relevant examination results during chemotherapy between the two groups. Multivariate linear regression analysis was used to identify independent risk factors for GC chemoresistance. Propensity score matching (PSM) was used to match the TNM stage data between the two groups, and Kaplan-Meier and log-rank tests were used to compare overall survival(OS)after matching. Results:The median number of chemotherapy cycles was 3 in the CR group and 4 in the NCR group. Compared with the NCR group, CR patients were younger [(66.3±9.4) years vs.(69.7±10.9)years], had a higher proportion of kidney transplantation history[6.8%(4/59) vs. 0.6%(1/169)], hypertension [50.8%(30/59) vs. 36.1%(61/169)], coronary heart disease[23.7%(14/59) vs.9.5% (16/169)], and hydronephrosis [13.6%(8/59) vs. 4.1%(7/169)](all P<0.05). CR patients had a higher proportion of T 4 stage [20.3% (12/59) vs. 5.9% (10/169)], N 2 stage [42.4% (25/59) vs. 8.3% (14/169)], multifocal tumors at initial diagnosis [59.3% (35/59) vs. 26.6% (45/169)], and larger maximum tumor diameter [2.5 (1.5, 3.4) cm vs. 1.6 (1.2, 2.5) cm] (all P < 0.05). The CR group showed higher proportions of long-term urinary tract infection (UTI) [90.1% (53/59) vs. 7.7% (15/169)], higher systemic immune-inflammation index (SII) [991.6 (451.0, 1577.9) vs. 462.8 (309.0, 766.7)], absolute neutrophil count [6.5(4.1, 7.8)× 10 9/L vs. 3.9 (2.9, 5.1)× 10 9/L], and platelet count [(220.0 ± 96.2)× 10 9/L vs. (191.0 ± 64.8)× 10 9/L], but lower albumin levels [(34.3 ± 4.2) g/L vs. (39.9 ± 3.8) g/L] and albumin-to-globulin ratio (A/G) [(1.2 ± 0.3) vs. (1.3 ± 0.2)] (all P < 0.05). Multivariate linear regression analysis identified only T stage and long-term UTI as independent risk factors for GC chemoresistance( P<0.05).The probability of GC chemoresistance in bladder cancer patients was calculated as: P(Chemoresistance)=[0.155×T stage+ 0.624×(long-term UTI)]×100%(long-term UTI = 1 if present during chemotherapy, otherwise=0). After PSM, survival analysis showed that the median OS was significantly higher in the NCR group (55 months) than that in the CR group (30 months) ( P=0.020). Conclusions:This study demonstrates that advanced T stage and persistent UTI are independent risk factors for GC chemotherapy resistance in locally advanced bladder cancer patients. Based on these findings, a predictive model for chemotherapy resistance probability was constructed using multivariate linear regression analysis.

The " no-accompany" service is an important measure to meet the patients′ needs for comprehensive, continuous, and high-quality diversified care and to enhance their medical experience. Starting in March 2024, the Second Affiliated Hospital of Zhejiang University School of Medicine launched a pilot " no-accompany" service in the breast surgery and dermatology wards. The hospital established a working team led by the nursing department and involving multiple administrative departments such as the medical affairs department, medical insurance office, and logistics management department. And the hospital has successfully advanced the implementation of the " no-accompany" ward program by establishing a multi-department collaborative management mechanism, standardizing the management of medical caregivers, developing a tiered fee scheme for the " no-accompany" service, and improving relevant service measures. The acceptance of the " no-accompany" service by patients increased from (3.93±0.83) in the second quarter of 2024 to (4.69±0.59) in the fourth quarter, and overall satisfaction rose from (4.18±0.73) to (4.50±0.54) (all P<0.001). The job competency of medical caregivers also improved significantly from (64.80±3.49) before starting work in March 2024 to (94.00±2.40) in the fourth quarter ( P<0.001). These findings provide a reference for the implementation of " no-accompany" services in public hospitals.

OBJECTIVE To explore the distribution and drug resistance of the pathogens causing the abdominal(pelvic)soft tissue infections in secondary or above medical institutions of Suzhou so as to provide bases for pre-vention and control of the infections.METHODS The surveillance data of abdominal(pelvic)soft tissue infections that were reported regularly from 58 member institutions of Suzhou from Jan.2020 to Dec.2023 were collected from the regional nosocomial infection surveillance platform by Suzhou nosocomial infection management and qual-ity control center.Totally 26 tertiary hospitals and 32 secondary hospitals were involved.RESULTS Most of the 1178 strains of pathogens were isolated from the tertiary hospitals,the proportion of gram-negative bacteria was the highest;Escherichia coli,Klebsiella pneumoniae and Enterococcus faecium ranked the top 3 species.The constituent ratio of carbapenem-resistant Klebsiella pneumoniae(CRKP)strains the was highest among the mul-tidrug-resistant organisms.The K.pneumoniae and CRKP strains were sensitive to tigecycline;the E.coli strains were highly sensitive to carbapenems,minocycline and piperacillin-tazobactam;Stenotrophomonas maltophilia strains were highly resistant to most of the antibiotics;Enterobacter cloacae strains were highly resistant to ampi-cillin-sulbactam but were highly sensitive to carbapenems;the drug resistance rate of the A.baumannii strains to tigecycline was less than 5％;the drug resistance rate of Pseudomonas aeruginosa strains to ticarcillin-clavulanic acid was highest.CONCLUSIONS The abdominal(pelvic)soft tissue infection is always mixed infections.The pathogens show severe drug resistance.It is necessary to strengthen the surveillance of etiological spectrum and drug resistance and conduct targeted guidance for clinical practice of diagnosis and treatment.

Objective:To utilize single-nucleus RNA sequencing(snRNA-seq) technology to investigate the primary cell subpopulations in human limb venous malformations (VMs) tissue and the role of the key gene RhoJ.Methods:Surgical resection specimens of VMs tissues and surrounding normal vein tissues were collected from 100 clinically diagnosed and screened patients with limb VMs at the Department of Hemangioma Surgery of the Third Affiliated Hospital of Zhengzhou University from January 2021 to December 2023. (1) Transcriptome analysis: Three patient samples were randomly selected for snRNA-seq studies, with the surgically removed VMs tissue serving as the experimental group and the surrounding normal vein tissue as the control group. A gene expression matrix for cell nuclei was established, followed by data quality control, dimensionality reduction, clustering, and cell type annotation. Cell-to-cell communication analysis was performed using the R language CellChat package to identify dominant cell subpopulations. The FindMarkers function was utilized to screen for differentially expressed genes (DEGs) between the dominant cell subpopulations of the experimental and control groups, and functional enrichment analysis was conducted. (2) Tissue experiments: An additional 35 patient samples from both the experimental and control groups were randomly selected. The mRNA and protein expression levels of the RhoJ gene were measured using real-time quantitative PCR (RT-qPCR) and Western blotting, respectively. (3) Validation experiments with human umbilical vein endothelial cells (HUVECs): HUVECs were transfected with pcDNA3.1-NC (blank control) and pcDNA3.1-RhoJ (plasmid expression vector carrying the RhoJ gene), respectively. The biological behavior differences between the two groups of cells were examined using the CCK-8 cell proliferation assay, Transwell invasion assay, and Matrigel angiogenesis assay. Measurement data conforming to a normal distribution were expressed as Mean±SD, and comparisons between the two groups were performed using an independent samples t-test. Results:Through CellChat intercellular communication analysis, it was discovered that endothelial cells were the predominant cell subpopulation in both the experimental and control groups, exhibiting strong communication links with other cell subpopulations. In the analysis of DEGs, it was found that the RhoJ gene in endothelial cells was significantly involved in the biological processes of angiogenesis and regulation. In tissue experiments, RT-qPCR and Western bloting results indicated that the relative expression levels of RhoJ mRNA (4.48±1.29 vs. 1.01±0.17) and protein (1.22±0.03 vs. 0.51±0.20) in the experimental group were significantly higher than those in the control group, with statistically significant differences ( P<0.01 for both). The results of the HUVECs validation experiment showed that the cell proliferation, invasion, and angiogenesis abilities of the pcDNA3.1-RhoJ group were significantly enhanced compared to the pcDNA3.1-NC group. Conclusion:Endothelial cells represent the dominant cell subpopulation during the occurrence and locally invasive progression of VMs, playing a crucial role in this process. The RhoJ gene is significant in regulating the biological behavior of VMs endothelial cells.

BACKGROUND: Delayed platelet engraftment is a common complication after umbilical cord blood transplantation (UCBT), and there is no standard therapy. Avatrombopag (AVA) is a second-generation thrombopoietin (TPO) receptor agonist (TPO-RA) that has shown efficacy in immune thrombocytopenia (ITP). However, few reports have focused on its efficacy in patients diagnosed with thrombocytopenia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: We conducted a retrospective study at the First Affiliated Hospital of the University of Science and Technology of China to evaluate the efficacy of AVA as a first-line TPO-RA in 65 patients after UCBT; these patients were compared with 118 historical controls. Response rates, platelet counts, megakaryocyte counts in bone marrow, bleeding events, adverse events and survival rates were evaluated in this study. Platelet reconstitution differences were compared between different medication groups. Multivariable analysis was used to explore the independent beneficial factors for platelet implantation. RESULTS: Fifty-two patients were given AVA within 30 days post-UCBT, and the treatment was continued for more than 7 days to promote platelet engraftment (AVA group); the other 13 patients were given AVA for secondary failure of platelet recovery (SFPR group). The median time to platelet engraftment was shorter in the AVA group than in the historical control group (32.5 days vs . 38.0 days, Z  = 2.095, P  = 0.036). Among the 52 patients in the AVA group, 46 achieved an overall response (OR) (88.5%), and the cumulative incidence of OR was 91.9%. Patients treated with AVA only had a greater 60-day cumulative incidence of platelet engraftment than patients treated with recombinant human thrombopoietin (rhTPO) only or rhTPO combined with AVA (95.2% vs . 84.5% vs . 80.6%, P  <0.001). Patients suffering from SFPR had a slightly better cumulative incidence of OR (100%, P  = 0.104). Patients who initiated AVA treatment within 14 days post-UCBT had a better 60-day cumulative incidence of platelet engraftment than did those who received AVA after 14 days post-UCBT (96.6% vs . 73.9%, P  = 0.003). CONCLUSION Compared with those in the historical control group, our results indicate that AVA could effectively promote platelet engraftment and recovery after UCBT, especially when used in the early period (≤14 days post-UCBT).

AIM: To investigate the mechanism of Hexue Mingmu Tablets(HXMMT)in improving diabetic retinopathy(DR)based on transcriptomics.METHODS: Zebrafish DR models were established by 3-day glucose induction(130 mmol/L)starting at 3 days post-fertilization(dpf). Larvae were randomized into four groups: control group(CG; aquaculture water), model group(MG; 130 mmol/L glucose), low-dose HXMMT treatment group(L-HX; 130 mmol/L glucose +7.5 mg/L HXMMT), and high-dose HXMMT treatment group(H-HX; 130 mmol/L glucose +75 mg/L HXMMT), with a 3-day intervention period until 6 dpf. The area and length of eyes, and body length of zebrafish were observed by stereomicroscopy, retinal morphology was observed by hematoxylin-eosin staining(HE), and retinal vessel diameter was observed under fluorescence microscope. Differentially expressed genes(DEGs)were identified by RNA-sequencing(RNA-seq)technology to further elucidate the molecular mechanism of HXMMT in improving DR in zebrafish, and the sequencing accuracy was validated through quantitative real-time polymerase chain reaction(qRT-PCR).RESULTS: HE staining demonstrated that the intervention with HXMMT significantly improved the disordered cell arrangement, widened gaps, and thickened inner nuclear layer(INL)in ganglion cell layer GCL); retinal vascular diameter quantification revealed that the retinal vessel diameter of the MG significantly increased compared with the CG, and it was significantly changed after the intervention of HXMMT, with significant efficacy in the H-HX(P<0.05); transcriptomics profiling identified 1 470 reversed DEGs, predominantly enriched in the AMPK signaling pathway, FoxO signaling pathway, retinal developmental processes, and tight junction regulation. Technical validation confirmed strong correlation between qRT-PCR and RNA-seq data(R2=0.8571, P<0.05).CONCLUSION: HXMMT may improve retinal vascular microcirculation disorders in DR by regulating core targets including vsx1, pde6c, arr3a, plk1, fbp1b, foxo1a, pcna, and cdk1, as well as synergistically modulating processes such as retinal development in camera-type eyes, visual perception, microtubule cytoskeletal organization, tight junctions, and the AMPK signaling pathway, Foxo signaling pathway.
