In the context of medical insurance payment reform,the sample hospital has implemented performance management optimization to effectively address the challenges posed by diagnosis-intervention packet(DIP)payment.Reform measures focused on disease quality,rational diagnosis and treatment,operational management,medical technological value,and policy orientation,and they have significantly optimized service ability and performance evaluation indexes of the hospital.Main achievements included a reduction in the cost consumption index and an increase in the clinical performance index,with the overall DIP payment rate increasing from 88.86%to 103.23%and a marked improvement in operational management.The quality control and operational efficiency of the hospital have been effectively enhanced by choosing proper DIP payment evaluation indexes and improving performance management,and provided strong support for the high-quality development of the hospital.

OBJECTIVES: To investigate the effect of orexin-A-mediated regulation of ionotropic glutamate receptors for promoting motor function recovery in rats with spinal cord injury (SCI). METHODS: Thirty-six newborn SD rats (aged 7-14 days) were randomized into 6 groups (n=6), including a normal control group, a sham-operated group, and 4 SCI groups with daily intrathecal injection of saline, DNQX, orexin-A, or orexin-A+DNQX for 3 consecutive days after PCI. Motor function of the rats were evaluated using blood-brain barrier (BBB) score and inclined plane test 1 day before and at 1, 3, and 7 days after SCI. For patch-clamp experiment, spinal cord slices from newborn rats in the control, sham-operated, SCI, and SCI+orexin groups were prepared, and ventral horn neurons were acutely isolated to determine the reversal potential and dynamic indicators of glutamate receptor-mediated currents under glutamate perfusion. RESULTS: At 3 and 7 days after SCI, the orexin-A-treated rats showed significantly higher BBB scores and grip tilt angles than those with other interventions. Compared with those treated with DNQX alone, the rats receiving the combined treatment with orexin and DNQX had significantly higher BBB scores and grip tilt angles on day 7 after PCI. In the patch-clamp experiment, the ventral horn neurons from SCI rat models exhibited obviously higher reversal potential and greater rise slope of glutamate current with shorter decay time than those from sham-operated and orexin-treated rats. CONCLUSIONS Orexin-A promotes motor function recovery in rats after SCI possibly by improving the function of the ionotropic glutamate receptors.

OBJECTIVE: To explore the genetic etiology of four fetuses with Uniparental disomy (UPD), and analyze their causes. METHODS: Four fetuses undergoing prenatal diagnosis at Wenzhou Central Hospital between November 2021 and July 2024 were selected as the study subjects. Genetic testing and diagnosis were carried out through G-banded chromosomal karyotyping, single nucleotide polymorphism array (SNP-array) and methylation multiplex ligation-dependent probe amplification (MS-MLPA). This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: L2024-11-028). RESULTS: The four cases of pathogenic UPD had involved chromosomes 2, 11, 15 and 16, respectively, of which 2 cases were accompanied by fetal ultrasound abnormalities, One fetus was shown a high risk by serological screening, while another showed a high risk by non-invasive DNA testing. The karyotype of fetus 1 was 45,X?,rob(13;15)(q10;q10), and its parents had both carried a Robertsonian translocation involving chromosomes 13 and 15, whilst the karyotypes of other three fetuses were all normal. Pedigree analysis indicated that the UPDs in three cases were paternally derived, and the remaining one was unknown. The causes of the four cases included imprinting syndrome in two cases, autosomal recessive disorder in one case, and cryptic mosaic trisomy in one case. CONCLUSION The clinical phenotypes of UPD are diverse, and the mechanisms are complex. Combined chromosomal karyotyping, SNP-array, MS-MLPA and other technologies are required to make a clear diagnosis for prenatal genetic counseling and postnatal management.

BACKGROUND: Several studies have demonstrated the occurrence of secondary tumors as a rare but significant complication of chimeric antigen receptor T (CAR-T) cell therapy, underscoring the need for a detailed investigation. Given the limited variety of secondary tumor types reported to date, a comprehensive characterization of the various secondary tumors arising after CAR-T therapy is essential to understand the associated risks and to define the role of the immune microenvironment in malignant transformation. This study aims to characterize the immune microenvironment of a newly identified secondary tumor post-CAR-T therapy, to clarify its pathogenesis and potential therapeutic targets. METHODS: In this study, the bone marrow (BM) samples were collected by aspiration from the primary and secondary tumors before and after CD19 CAR-T treatment. The CD45 + BM cells were enriched with human CD45 microbeads. The CD45 + cells were then sent for 10× genomics single-cell RNA sequencing (scRNA-seq) to identify cell populations. The Cell Ranger pipeline and CellChat were used for detailed analysis. RESULTS: In this study, a rare type of secondary chronic myelomonocytic leukemia (CMML) were reported in a patient with diffuse large B-cell lymphoma (DLBCL) who had previously received CD19 CAR-T therapy. The scRNA-seq analysis revealed increased inflammatory cytokines, chemokines, and an immunosuppressive state of monocytes/macrophages, which may impair cytotoxic activity in both T and natural killer (NK) cells in secondary CMML before treatment. In contrast, their cytotoxicity was restored in secondary CMML after treatment. CONCLUSIONS This finding delineates a previously unrecognized type of secondary tumor, CMML, after CAR-T therapy and provide a framework for defining the immune microenvironment of secondary tumor occurrence after CAR-T therapy. In addition, the results provide a rationale for targeting macrophages to improve treatment strategies for CMML treatment.

Objective:To explore the current status and influencing factors of intrinsic capacity in elderly patients with Parkinson's disease.Methods:Convenience sampling was used to select 306 elderly patients with Parkinson's disease who attended Xuanwu Hospital of Capital Medical University from March to September 2024 for the study. Influencing factors were screened based on the health ecology model. Elderly patients with Parkinson's disease were surveyed using the General Information Questionnaire, Connor-Davidson Resilience Scale, Family APGAR Scale, Social Support Rating Scale, and Intrinsic Capacity Assessment Tool. Multiple linear regression was used to analyze the factors influencing the total score and the scores of each dimension of intrinsic capacity in elderly patients with Parkinson's disease.Results:A total of 306 questionnaires were distributed and 301 valid questionnaires were recovered, with a valid recovery rate of 98.37% (301/306). The total intrinsic capacity score of 301 elderly patients with Parkinson's disease was (67.21±11.47), of which 297 elderly patients with Parkinson's disease had impaired intrinsic capacity, and the rate of impaired intrinsic capacity was 98.7% (297/301). The dimensions in descending order of impairment were motor [89.7% (270/301) ], mental [76.1% (229/301) ], sensory [70.4% (212/301) ], vitality [38.2% (115/301) ], and cognitive [25.6% (77/301) ]. Multiple linear regression analysis showed that age, Hoehn-Yahr staging, levodopa equivalent dosage, activity of daily living, history of falls, regular exercise, psychological resilience, social support, and monthly income were the factors influencing the total intrinsic capacity score of elderly patients with Parkinson's disease ( P<0.05) and heterogeneity of influencing factors in each dimension. Conclusions:Elderly patients with Parkinson's disease have a high rate of impaired intrinsic capacity, with the motor dimension being the most severely impaired. Healthcare professionals should pay attention to the assessment of the intrinsic capacity of elderly patients with Parkinson's disease, and customize interventions according to the influencing factors to promote the functioning of elderly patients so as to reduce the burden of care on families and society.

Objective:To explore the correlations of sleep quality and architecture with heart rate variability (HRV) in patients with stenoses of vertebrobasilar artery system and internal carotid artery system.Methods:A retrospective study was performed; 72 patients with stenosis or occlusion of the head and neck arteries (not resulting in cerebral infarction) admitted to Department of Neurology, Second Affiliated Hospital of Zhengzhou University from June 2023 to June 2024 were chosen, including 33 patients with moderate-to-severe stenosis or occlusion of the vertebrobasilar system (VB group) and 39 patients with moderate-to-severe stenosis or occlusion of the internal carotid artery system (ICA group). Pittsburgh sleep quality index (PSQI) and polysomnography (PSG) were used to evaluate the sleep quality and architecture, respectively; and 24-hour ambulatory electrocardiogram was used to assess the HRV. Differences in PSQI score, PSG and HRV parameters between the two groups were compared; partial correlation analysis was used to explore the correlations of HRV parameters with PSQI scores and PSG parameters; multivariate linear regression was used to analyze the independent influencing factors for HRV.Results:(1) Compared with the ICA group, the VB group exhibited significantly higher PSQI scores, spontaneous arousal index (SAI), ratio of time of stage 1 non-rapid eye movement sleep/total sleep time (T N1/T t), and apnea-hypopnea index (AHI), while significantly lower ratio of time of rapid eye movement sleep/total sleep time (T R/T t), spindle wave density in stage 2 non-rapid eye movement sleep (N2), lowest blood oxygen saturation, standard deviation of normal to normal intervals (SDNN) of all sinus beats, low-frequency power (LF), and high-frequency power (HF, P<0.05). (2) In both VB group and ICA group, SDNN was negatively correlated with PSQI score ( r=-0.461, P=0.020; r=-0.378, P=0.036). In the VB group, SDNN was negatively correlated with T N1/T t ( r=-0.467, P=0.019) and SAI ( r=-0.551, P=0.004), and positively correlated with ratio of time of stage 3 non-rapid eye movement sleep/total sleep time (T N3/T t, r=0.686, P<0.001) and spindle wave density in N2 ( r=0.518, P=0.008); LF and HF were negatively correlated with SAI ( r=-0.481, P=0.015; r=-0.564, P=0.003). In the ICA group, HF was negatively correlated with spindle wave density in N2 ( r=-0.369; P=0.041). (3) Multivariate linear regression results indicated that T N3/T t (β=0.348, P=0.018), SAI (β=-0.330, P=0.018), and spindle wave density in N2 (β=0.286, P=0.013) were independent influencing factors for Ln_SDNN in patients with moderate-to-severe stenosis or occlusion of the vertebrobasilar system. Conclusion:Patients with stenosis or occlusion of the vertebrobasilar system exhibit poorer subjective sleep quality, increased light sleep, heightened arousal, and reduced sleep stability compared with those with stenosis or occlusion of the internal carotid artery system, which may be caused by the imbalance of autonomic nerve function.
