OBJECTIVES:
To evaluate the value of ⁶⁸Ga-DOTATATE and ¹⁸F-FDG PET/CT imaging in staging and treatment decision for gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN).
METHODS:
This retrospective analysis was conducted in 49 patients with GEP-NEN undergoing 18F-FDG and 68Ga-DOTATATE PET/CT imaging at our hospital from August, 2020 to March, 2023, including 34 newly diagnosed patients and 15 patients with recurrence or metastasis after treatment. GEP-NEN were classified into G1, G2, and G3 neuroendocrine tumors (NET) and neuroendocrine carcinomas (NEC) based on pathological typing. The detection efficiency were classified into 4 patterns based on the number of positive tumor lesions detected by the two tracers: 68Ga-DOTATATE>18F-FDG (A); 68Ga-DOTATATE=18F-FDG (B); 68Ga-DOTATATE<18F-FDG (C); and complementation (D). The value of dual-modality imaging in staging and treatment decision were evaluated by visual analysis.
RESULTS:
In the 49 patients with GEP-NEN, 68Ga-DOTATATE PET/CT was superior to 18F-FDG PET/CT for detecting systemic tumor lesions (P<0.001) and more sensitive for detecting primary/recurrent lesions, lymph node metastasis, liver metastasis, and bone metastasis (P<0.05), while 18F-FDG PET/CT had higher detection rates for lung metastasis and peritoneal metastasis (P<0.05). In terms of the detection efficiency, Pattern A was found in 46.9% (23/49) patients, Pattern B in 38.8% (19/49), Pattern C in 12.2% (6/49), and Pattern D in 2.0% (1/49). The complementary value of ¹⁸F-FDG PET/CT to ⁶⁸Ga-DOTATATE PET/CT was 0% in G1 NET patients (0/13), 8.3% in G2 NET patients (2/24), 50% in G3 NET patients (3/6), and 33.3% in NEC patients (2/6). 12.2% (6/49) of the patients had their staging confirmed or changed due to additional lesions detected by ¹⁸F-FDG PET/CT imaging, resulting subsequently in establishment or adjustment of their treatment plans.
CONCLUSIONS
68Ga-DOTATATE PET/CT imaging should be the primary choice for GEP-NEN patients. Additional ¹⁸F-FDG PET/CT imaging can potentially improve precision of staging and treatment decision-making for G2, G3 and NEC patients but provides virtually no clinical benefits for G1 NET patients.

Objective:To analyze the changes in the costs of hospital rehabilitation after the reform of health insurance payments in the past 6 years, and to identify relevant factors which can provide a reference for the reform of the health insurance payment system in rehabilitation department.Methods:Information on 16, 827 patients hospitalized in the rehabilitation department of The First Affiliated Hospital of Xi′an Jiaotong University between May 2018 and May 2024 was collected and subjected to non-parametric analysis.Results:The average hospitalization cost of rehabilitation department patients over the six years was Y14, 574.92±10, 524.79. During that time the proportion of the cost attributable to Western medicine decreased from 17.1% in 2018 to 7.6% in 2024. The proportion of the patients with hypertension was 51.94%, followed by diabetes mellitus (20.10%). Those with infections had the highest total hospitalization costs. Motor disorders were the most common dysfunction (59.02%), followed by speech disorders (17.45%). Patients with swallowing disorders had the highest hospitalization costs. After the payment system shifted from fee-for-service (FFS) to payment by diagnosis-related group (DRG) in 2023, the average daily inpatient expenditures for rehabilitation patients with all types of diseases gradually declined, reaching its lowest level in 2024.Conclusions:After the health insurance payments shifted from FFS to DRG, the proportion of in patients′ total drug costs decreased annually, and the average daily costs of patients with different types of diseases also decreased significantly, but the comprehensive service fee and diagnostic costs increased.

After 6 months, the children were divided into two groups according to the treatment effect, 13 cases in the ineffective group and 16 cases in the effective group, the peripheral blood of the children was collected, the blood mononuclear cells were isolated for transcriptome sequencing, the differentially expressed genes between the groups were analyzed, the signaling pathways and metabolic pathways related to the efficacy of TNFi were analyzed by GO and KEGG enrichment, and the mechanism related to the efficacy of TNFi was explored. This study was approved by Medical Ethics Committee of the Guangzhou Women and Children′s Medical Center of Guangzhou Medical University (Ethics No.: 2023-330B00).Results:There was a statistically significant difference in the gender and age distribution between the two groups of children ( P<0.05), while no statistically significant differences were observed in disease duration, rheumatoid antibody levels, or JIA subtypes ( P> 0.05). After sequencing data quality control and comparison of reference genomes, a total of 18 523 protein-coding genes were identified in all children′s samples. A total of 705 differentially expressed genes (DEGs) were identified between the effective group and the invalid group through differential analysis, of which 579 were up-regulated in the effective group and 126 in the inactive group. GO function and KEGG pathway enrichment analysis showed that DEG was significantly enriched in 55 GO entries and 32 KEGG metabolic pathways, which were mainly related to IL-1β; production and regulation, cytokine production and regulation, cytokine-cytokine receptor interaction, immune response regulation, and Toll-like receptor signaling pathway. Conclusion:DEG between the effective and ineffective groups of TNFi treatment may be involved in the biological processes such as cytokine production and regulation, cytokine-receptor interaction, and immune response regulation, which will be helpful to predict the efficacy and prognosis of TNFi treatment for JIA.

Chinese Journal of Postgraduates of Medicine 2025;48(3):250-256
Objective:To explore the influencing factors of brain injury in children with neonatal asphyxia after resuscitation.Methods:The clinical data of 180 children with neonatal asphyxia from January 2017 to January 2024 in Shijiazhuang Maternal and Child Health Hospital were retrospectively analyzed, and all children were received resuscitation treatment. The children were divided into modeling group (126 cases) and validation group (54 cases) in a 7∶3 ratio. Among the children in modeling group, 51 children combined brain injury (brain injury subgroup), and 75 children did not combine brain injury (non-brain injury subgroup). The general data were recorded, and the continuous variables were determined by the receiver operating characteristic (ROC) curve to determine the optimal cut-off value. Multivariate Logistic regression analysis was used to analyze the independent risk factors of brain injury in children with neonatal asphyxia after resuscitation. The R language software "rms" package was used to construct a nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation. The nomogram model was internally verified by the calibration curve, and the prediction efficiency of the nomogram model was evaluated by the decision curve and ROC curve.Results:There was no statistical difference in general data between modeling group and validation group ( P>0.05). The gestation age<37 weeks proportion, severe asphyxia proportion, Ⅱ to Ⅲ grade amniotic fluid contamination proportion, intrauterine distress proportion and blood lactate in brain injury subgroup were significantly higher than those in non-brain injury subgroup: 60.78% (31/51) vs. 38.67% (29/75), 37.25% (19/51) vs. 17.33% (13/75), 27.45% (14/51) vs. 10.67% (8/75), 47.06% (24/51) vs. 26.67% (20/75) and (2.64 ± 0.61) mmol/L vs. (2.21 ± 0.56) mmol/L, and there were statistical differences ( P<0.05 or <0.01); there were no statistical differences in gender composition, birth weight, maternal age, maternal history of adverse pregnancy and childbirth, mode of delivery, parity, abnormal amniotic fluid volume, abnormal fetal position, abnormal umbilical cord, abnormal placenta, systolic blood pressure, diastolic blood pressure, body temperature and blood glucose between the two groups ( P>0.05). ROC curve analysis result showed that the optimal cutoff value of blood lactate was 2.59 mmol/L. Multivariate Logistic regression analysis result showed that the young gestation age, severe asphyxia, Ⅱ to Ⅲ grade amniotic fluid contamination, intrauterine distress and high blood lactate were independent risk factors of brain injury in children with neonatal asphyxia after resuscitation ( OR = 2.854, 3.428, 3.405, 3.427 and 7.844; 95% CI 1.166 to 6.983, 1.263 to 9.305, 1.076 to 10.768, 1.358 to 8.645 and 3.080 to 19.978; P<0.05 or <0.01). The gestation age, degree of asphyxia, amniotic fluid contamination, intrauterine distress and blood lactate were used as predictors to construct a nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation. The calibration curve analysis result showed that the calibration curve of the nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation tended towards the ideal curve ( C- index = 0.824, 95% CI 0.745 to 0.903). The decision curve analysis result showed that, when the risk threshold was greater than 0.18, the clinical net benefits provided by the nomogram model were higher than those of a single independent risk factor, and it could provide significant additional clinical net benefits in predicting the high risk of brain injury in children with neonatal asphyxia after resuscitation. ROC curve of internal validation analysis result that the curve (AUC) of the nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation was 0.824 (95% CI 0.744 to 0.903). ROC curve of external validation result showed that the AUC of the nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation was 0.838 (95% CI 0.714 to 0.962). Conclusions:The gestation age, degree of asphyxia, amniotic fluid contamination, intrauterine distress and blood lactate are independent risk factors for brain injury in children with neonatal asphyxia after resuscitation. The nomogram model constructed based on these factors has a high clinical benefit in predicting brain injury in children with neonatal asphyxia after resuscitation.

Objective To investigate the role of STK4-AS1 in regulating the proliferation,invasion,and migration of esophageal squamous cell carcinoma(ESCC)cells through the MYG1/Notch signaling pathway.Methods Quantitative real-time PCR(qRT-PCR)was used to detect the expression of STK4-AS1 in ESCC cells.MTS assay,wound healing and Transwell assay were conducted to explore the proliferation,migration,and invasion abilities in each group in Eca109 and Kyse150 cells.mRNA sequencing(mRNA-seq)was used to detect the down-stream target genes of STK4-AS1.KEGG functional enrichment analyses were used to predict the possible biological processes and signaling pathways.qRT-PCR and western blot were performed to identify mRNA expression of MYG1 and the key downstream transcription factors HES1,HES5,and HEY1 of the Notch signaling pathway,as well as the protein expression of NICD1.Co-transfection plasmids(for over-expressing STK4-AS1 and MYG1)were used to detect the mRNA expression of HES1,HES5,and HEY1 and the protein expression of NICD1 which acted as the key downstream transcription factors in the Notch signaling pathway,as well as the effects on the proliferation,migration,and invasion abilities of ESCC cells.Results The expression of STK4-AS1 was decreased in ESCC cell lines(P<0.01).Over-expression of STK4-AS1 inhibited the proliferation,migration and invasion abilities in Eca109 and Kyse150 cells(P<0.05).STK4-AS1 negatively regulated the expression of MYG1(P<0.01),and the expression of MYG1 was increased in ESCC cell lines(P<0.01).Over-expression of MYG1 could partially reverse the effect of STK4-AS1 on the malignant biological behavior of Eca109 and Kyse150 cells(P<0.05),as well as the mRNA expressions of HES1,HES5,and HEY1 and the protein expression of NICD1(P<0.05).Conclusion STK4-AS1 affects the malignant biological behaviors of ESCC through the MYG1/Notch signaling pathway.

The clinical data of an infant with chondrodysplasia accompanied by early-onset epilepsy and medial temporal lobe dysgenesis due to the FGFR3 gene mutation, who was treated in the Affiliated Hospital of Jining Medical University in March 2024 were retrospectively analyzed.The 9-day-old male infant presented with frequent apnea at 5 hours after birth and experienced first seizure at 24 hours after birth.Physical examination revealed short limbs.Magnetic resonance imaging (MRI) showed abnormal changes in bilateral temporal lobes, hippocampal structure and bilateral lateral ventricular temporal angles, so cerebral developmental abnormalities were considered in this child.Whole exome sequencing confirmed a heterozygous variation in the FGFR3 gene [c.1620C>A(p.Asn540Lys)].After receiving Phenobarbital monotherapy, the child still had frequent seizures, but the seizure was completely controlled after the additional use of Lvetiracetam.To August 2024, a total of 14 patients with achondroplasia, epilepsy, and medial temporal lobe dysplasia caused by FGFR3 gene mutations were identified.These patients typically experienced frequent seizures in early infancy, which could be accompanied by apnea and psychomotor retardation.MRI consistently showed abnormal development of bilateral temporal lobes and hippocampus.Seizures were hardly controlled by anti-seizure medications, and Phenobarbital was effective in some cases.Whole exome sequencing revealed gene variations of c.1620C>A or c. 1620C>G (p.Asn540Lys).Patients with achondroplasia caused by FGFR3 gene mutations may present with early-onset epilepsy and medial temporal lobe dysplasia.Early seizures are frequent and difficult to control, and Phenobarbital is effective in some cases.
