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 analyze the clinical and genetic characteristics of a Chinese pedigree affected with congenital Isolated growth hormone deficiency (IGHD). METHODS: A pedigree presenting with Pituitary stalk interruption syndrome (PSIS) (including the proband, his two younger sisters and both parents) who had visited the Capital Institute of Pediatrics Affiliated to Capital Medical University in September 2020 was selected as the study subject. Clinical data were collected. Peripheral blood samples were collected from the proband and his family members. Following the extraction of genomic DNA, whole-exome sequencing (WES) was carried out, and candidate variants were validated by Sanger sequencing. The pathogenicity of the candidate variants was classified based on guidelines from the American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of the Institute Pediatrics of Capital Medical University (Ethics No.: SHERLL2025033). RESULTS: The proband and one younger sister (Ⅱ3) presented with growth retardation, short stature, and a doll-like facies. Another younger sister (Ⅱ2) and both parents had normal heights and appearance. Sanger sequencing confirmed that the proband and his younger sister (Ⅱ3) both harbored compound heterozygous variants of the GHRHR gene, namely c.776C>A (p.T259K) and c.1166G>A (p.R389Q). The other younger sister (Ⅱ2) and the parents were heterozygous carriers. The c.1166G>A (p.R389Q) variant was unreported previously. Based on the guidelines from the ACMG, it was classified as variant of uncertain significance (PM2_Supporting+BP4). Bioinformatics analysis indicated a deleterious effect on the protein function. CONCLUSION Variants of the GHRHR gene probably underlay the pathogenesis of IGHD in this pedigree. Above finding has provided a basis for the clinical diagnosis and genetic counseling for this family.

This paper will review the development status, application advantages and existing problems of clinical decision support system in the field of clinical nursing of Traditional Chinese Medicine, aiming to provide reference for the development of a more specialized and systematic clinical decision support system for clinical nursing of Traditional Chinese Medicine.

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 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.
