OBJECTIVE To investigate the apoptosis-inducing effect of esculetin （Esc） on acute myeloid leukemia （AML） HL-60 cells by regulating the protein kinase B （AKT）/S-phase kinase-associated protein 2 （SKP2）/MutT homolog 1 （MTH1） pathway. METHODS AML HL-60 cells were randomly divided into control group （routine culture）， Esc low-concentration group （L-Esc group， 25 μmol/L Esc）， Esc medium-concentration group （M-Esc group， 50 μmol/L Esc）， Esc high-concentration group （H-Esc group， 100 μmol/L Esc）， and high-concentration of Esc+ SC79 （AKT agonist） group （100 μmol/L Esc+5 μmol/L SC79）. Cell proliferation in each group was detected by MTT assay and colony formation assay. The level of reactive oxygen species （ROS） in cells was measured by using the CM-H2DCFDA fluorescent probe. Cell apoptosis was analyzed by flow cytometry. Western blot assay was performed to detect the expression levels of apoptosis-related proteins [B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cleaved caspase-3]， AKT/SKP2/MTH1 pathway-related proteins （p-AKT， AKT， SKP2， MTH1）， along with the upstream and downstream proteins of AKT phosphatidylinositol 3-kinase （PI3K）， cyclin-dependent kinase inhibitor 1 （P21） and cyclin-dependent kinase inhibitor 1B （P27）. RESULTS Compared with control group， the cell viability， colony number， and the phosphorylation levels of AKT and PI3K proteins as well as protein expressions of SKP2， MTH1 and Bcl-2 were significantly decreased （P＜0.05）， while ROS level， apoptosis rate， and the expression levels of Bax， cleaved caspase-3， P21 and P27 proteins were significantly increased （P＜0.05）. Moreover， the effects of Esc exhibited concentration-dependence （P＜0.05）. Compared with H-Esc group， above indexes of high-concentration of Esc+ SC79 group were reversed significantly （P＜0.05）. CONCLUSIONS Esc may promote massive ROS production and induce activation of apoptosis in HL-60 cells by inhibiting the AKT/SKP2/MTH1 pathway， thus inhibiting the proliferation of HL-60 cells.

Objective:To evaluate the effect of umbilical cord milking (UCM) on neonatal outcomes after cesarean section.Methods:Chinese and English databases (including CNKI, Wanfang, China Biology Medicine Disc, VIP, Yiigle, PubMed, Embase, CINAHL, Web of Science, the Cochrane Library, and Google Scholar) and ClinicalTrials.gov were retrieved from the inception to July 2023. Randomized controlled trials regarding UCM in neonates from different races who were born by cesarean section were included. The outcomes were postnatal hemoglobin level, hematocrit value, peak serum bilirubin level, phototherapy, cord blood pH value, intraventricular hemorrhage, death, polycythemia, neonatal necrotizing enterocolitis, and Apgar score. The risk of bias among the included studies was confined to low or possible risk according to the Cochrane Risk of Bias Assessment Tool 2.0. RevMan5.3 was used for meta-analysis, and subgroup analysis was performed among neonates with different gestational ages. The certainty of evidence was evaluated using the grades of recommendations assessment, development, and evaluation (GRADE) framework.Results:A total of 11 articles involving 2 347 neonates (1 322 full-term and 1 025 preterm infants) were included. Meta-analysis results showed that: (1) Compared with the immediate cord clamping, UCM increased the hemoglobin level within 24 h and 48-72 h after birth ( MD=1.40, 95% CI: 1.11-1.70, Z=9.32; MD=0.86, 95% CI: 0.69-1.02, Z=10.02, both P<0.01), hematocrit value within 24 h and 48-72 h after birth ( MD=2.73, 95% CI: 0.18-5.29, Z=2.09, P=0.04; MD=3.57, 95% CI: 2.29-4.85, Z=5.46, P<0.01). However, no significant differences were found in the peak bilirubin level, phototherapy, cord blood pH, and Apgar score at 1 and 5 min (all P>0.05). (2) Compared with delayed cord clamping, UCM increased the hemoglobin level ( MD=0.83, 95% CI: 0.75-0.91, Z=20.11, P<0.01) and hematocrit value ( MD=2.34, 95% CI: 1.25-3.43, Z=4.20, P<0.01) within 24 h after birth, but not in the hematocrit value at 48-72 h after birth ( MD=－0.38, 95% CI:－2.27-1.52, Z=0.39, P=0.70) or the peak bilirubin level ( MD=－0.65, 95% CI:－2.16-1.04, Z=0.69, P=0.49). Sensitivity analysis showed that for full-term neonates born by cesarean section, the peak bilirubin level in the UCM group was significantly lower than that in the delayed cord clamping group ( MD=－1.30, 95% CI:－2.26-0.34, Z=2.66, P<0.01). Still, the incidence of phototherapy, intraventricular hemorrhage (grade Ⅰ-Ⅳ), death, polycythemia, neonatal necrotizing enterocolitis, and Apgar score at 1 min and 5 min showed no statistical differences (all P>0.05). Conclusions:UCM could increase the short-term postnatal hemoglobin and hematocrit levels in neonates born by cesarean section, which might prevent neonatal anemia in the short term without increasing the adverse neonatal outcomes. Little effects were observed on the peak bilirubin level, phototherapy, polycythemia, etc. More high-quality and large-sample randomized controlled trials are needed in the future.

To analyze the clinical characteristics and follow-up data of Chinese patients with calcium-sensing receptor (CaSR) signaling pathway related hypercalcemia. A retrospective analysis was conducted on six children with hypercalcemia admitted to Department of Endocrinology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from July 2017 to November 2022. Summarized the clinical and pathogenic variants, as well as follow-up data. The results showed that 3 were female and 3 were male of the 6 cases, aged from 2 months to 8 years at the consultation. The clinical symptoms varied from asymptomatic hypercalcemia to vomiting, dehydration, and growth retardation,as well as epilepsy and intellectual disability. Except for 1 case, which showed a significant increase in blood calcium (4.63 mmol/L), the blood calcium of other cases ranged from 2.98 to 3.17 mmol/L. Among the 6 patients, 5 had elevated parathyroid hormone, and 1 was normal. Three cases showed a significant decrease in 24-hour urinary calcium to creatinine ratio. Whole exome sequencing revealed that one patient had compound heterozygous variants and four had a heterozygous variants of CaSR gene, one patient had a heterozygous variant of AP2S1 gene. 1 case underwent total parathyroidectomy, followed by calcium supplementation, 3 cases received salmon calcitonin treatment, and 2 cases accepted low calcium diet, blood calcium levels were all controlled well. In conclusion, CaSR signaling pathway related hypercalcemia is rare. Gene detection is essential for children with hypercalcemia. Familial hypocalcemia hypercalcemia (FHH) can be effectively treated with salmon calcitonin.

OBJECTIVE: To explore the clinical characteristics and genetic basis for three children with Congenital chlorine diarrhea (CCD). METHODS: Three children with CCD who attended the Affiliated Children's Hospital of Capital Pediatric Institute from June 2014 to August 2020 were selected as the research subjects. Peripheral blood samples of the three children and their parents were collected for genetic testing. And the results were verified by Sanger sequencing. RESULTS: The clinical manifestations of the three children have included recurrent diarrhea, with various degrees of hypochloremia, hypokalemia and refractory metabolic alkalosis. Genetic testing revealed that the three children have all carried variants of the SLC26A3 gene, including homozygous c.1631T>A (p.I544N) variants, c.2063_1G>T and c.1039G>A (p.A347T) compound heterozygous variants, and c.270_271insAA(p.G91kfs*3) and c.2063_1G>T compound heterozygous variants. Sanger sequencing confirmed that all of the variants were inherited from their parents. CONCLUSION The variants of the SLC26A3 gene probably underlay the CCD in these children. Above finding has enriched the spectrum of SLC26A3 gene variants.

Subcutaneous panniculitis-like T-cell lymphoma (SPTL) is an extremely rare, indolent skin malignancy that can be difficult to distinguish from autoimmune disease-associated panniculitides. Here, we describe a 12-year-old boy who was diagnosed at age 7 years with dermatomyositis with classical manifestations, including poikiloderma, Gottron’s sign, and symmetric muscle weakness. Recently, the boy presented multiple subcutaneous nodules and fever. Histopathological examination and immunohistochemical staining revealed coexistence of SPTL. To our knowledge, this is the first case of dermatomyositis accompanied with SPTL. This case alert clinical physicians of the possibility of SPTL should be considered when a patient with dermatomyositis has new lesions presenting as nodules and unknown fever.

Objective:To explore the relationship between stigma, psychological resilience and quality of life in patients with stable schizophrenia.Methods:This study is a cross-sectional study. From January to December 2021, 305 patients with stable schizophrenia who were treated in the Outpatient Department of the Affiliated Brain Hospital of Nanjing Medical University were selected by convenient sampling. The survey was carried out by using the General Information Questionnaire, the World Health Organization Quality of Life-Brief Form (WHOQOL-BREF) , the Connor-Davison Resilience Scale (CD-RISC) , and the Perceived Devaluation Discrimination (PDD) . Pearson correlation analysis was used to analyze the relationship between quality of life, stigma and psychological resilience of schizophrenia patients. The structural equation model was established using AMOS 25.0 and the intermediary effect was verified. A total of 305 questionnaires were distributed and 286 valid questionnaires were recovered, with an effective recovery rate of 93.8% (286/305) .Results:Among 286 patients with stable schizophrenia, the scores of psychological resilience, stigma and quality of life were (56.49±14.28) , (29.62±5.70) and (63.15±11.67) respectively. There was a positive correlation between the psychological resilience and the quality of life ( r=0.461, P<0.01) , a negative correlation between the stigma and the quality of life ( r=-0.328, P<0.01) , and a negative correlation between the stigma and the psychological resilience ( r=-0.309, P<0.01) . The results of intermediary effect analysis showed that psychological resilience played a part of intermediary role between the stigma and the quality of life, and the indirect effect was statistically significant (β=- 0.167, P<0.001) , the intermediary effect accounted for 32.2% of the total effect. Conclusions:Psychological resilience is an intermediary variable between the stigma and the quality of life in patients with stable schizophrenia. Nurses should carry out intervention strategies based on the impact of psychological resilience path to reduce the patients' stigma and improve their quality of life.
