Triple-negative breast cancer (TNBC) represents a distinctive subtype, characterized by the absence of estrogen receptors, progesterone receptors, and human epidermal growth factor receptor 2 (HER2). Due to its high inter-tumor and intra-tumor heterogeneity, TNBC poses significant chanllenges for personalized diagnosis and treatment. The advant of clustered regular interspaced short palindromic repeats (CRISPR) technology has profoundly enhanced our understanding of the structure and function of the TNBC genome, providing a powerful tool for investigating the occurrence and development of diseases. This review focuses on the application of CRISPR/Cas technology in the personalized diagnosis and treatment of TNBC. We begin by discussing the unique attributes of TNBC and the limitations of current diagnostic and treatment approaches: conventional diagnostic methods provide limited insights into TNBC, while traditional chemotherapy drugs are often associated with low efficacy and severe side effects. The CRISPR/Cas system, which activates Cas enzymes through complementary guide RNAs (gRNAs) to selectively degrade specific nucleic acids, has emerged as a robust tool for TNBC research. This technology enables precise gene editing, allowing for a deeper understanding of TNBC heterogeneity by marking and tracking diverse cell clones. Additionally, CRISPR facilitates high-throughput screening to promptly identify genes involved in TNBC growth, metastasis, and drug resistance, thus revealing new therapeutic targets and strategies. In TNBC diagnostics, CRISPR/Cas was applied to develop molecular diagnostic systems based on Cas9, Cas12, and Cas13, each employing distinct detection principles. These systems can sensitively and specifically detect a variety of TNBC biomarkers, including cell-specific DNA/RNA and circulating tumor DNA (ctDNA). In the realm of precision therapy, CRISPR/Cas has been utilized to identify key genes implicated in TNBC progression and treatment resistance. CRISPR-based screening has uncovered potential therapeutic targets, while its gene-editing capabilities have facilitated the development of combination therapies with traditional chemotherapy drugs, enhancing their efficacy. Despite its promise, the clinical translation of CRISPR/Cas technology remains in its early stages. Several clinical trials are underway to assess its safety and efficacy in the treatment of various genetic diseases and cancers. Challenges such as off-target effects, editing efficiency, and delivery methods remain to be addressed. The integration of CRISPR/Cas with other technologies, such as 3D cell culture systems, human induced pluripotent stem cells (hiPSCs), and artificial intelligence (AI), is expected to further advance precision medicine for TNBC. These technological convergences can offer deeper insights into disease mechanisms and facilitate the development of personalized treatment strategies. In conclusion, the CRISPR/Cas system holds immense potential in the precise diagnosis and treatment of TNBC. As the technology progresses and becomes more costs-effective, its clinical relevance will grow, and the translation of CRISPR/Cas system data into clinical applications will pave the way for optimal diagnosis and treatment strategies for TNBC patients. However, technical hurdles and ethical considerations require ongoing research and regulation to ensure safety and efficacy.

Background: Delirium in the post-anesthesia care unit (PACU) may be associated with worse outcomes in children with moyamoya disease (MMD). This retrospective study aimed to describe the prevalence of PACU delirium in children with MMD and investigate its risk factors. Methods: Patients with MMD aged < 15 years who underwent indirect revascularization between January 2014 and October 2023 were included in this study. Delirium was assessed using the Pediatric Anesthesia Emergence Delirium Scale. Potential risk factors for PACU delirium were evaluated using multivariate logistic regression. Results: PACU delirium occurred in 245 (33%) of the 750 hemispheric procedures performed in 522 patients. Delirium was associated with a higher incidence in patients undergoing the first revascularization (37%) than in those undergoing the second (25%; P = 0.002). Cerebral infarction as the initial presentation (odds ratio [OR]: 4.64, first revascularization), high pediatric moyamoya magnetic resonance imaging (MRI) score (OR: 2.75, first revascularization; OR: 3.50, second revascularization), and high intraoperative mean arterial pressure variability (mmHg/min) (OR: 9.17, first revascularization; OR: 8.82, second revascularization) were associated with PACU delirium. Conversely, total intravenous anesthesia (TIVA) was associated with a lower incidence of PACU delirium (OR: 0.46, first revascularization; OR: 0.25, second revascularization). Conclusions A significant proportion of patients with MMD developed delirium in the PACU. High intraoperative blood pressure variability and preoperative MRI lesions are independent risk factors for PACU delirium in children with MMD. TIVA may exert a protective effect against PACU delirium. Further studies are required to clarify the causality of these associations.

[Objective] To use Platelet Additive Solution Ⅲ M to suspend concentrated platelets and evaluate their quality at different storage periods, in order to investigate the optimal ratio of Ⅲ M to plasma in the medium for storing concentrated platelets. [Methods] Disposable plastic blood bags with platelet storage bags were used to collect whole blood from healthy voluntary blood donors, and concentrated platelets were collected by plasma-rich method, with a volume of about 50 mL and ≥4.0×10¹⁰ platelets contained in each bag. According to the Platelet Addictive Solution ⅢM/plasma volume ratio in the medium of suspended platelets, the platelets were divided into 3 groups: control group (plasma only), experimental group 1(Platelet Addictive Solution ⅢM/plasma volume ratio of 6.5∶3.5) and experimental group 2 (low plasma group, Platelet Addictive Solution ⅢM/plasma volume ratio of 9∶1), each group of 50 samples. Three groups of platelets were stored at (22±2) ℃ at a flat-bed shaker, and 5 mL were sampled by sterile connection at day 1, 3, 5 and 7 respectively to detect platelet count, pH value, lactate dehydrogenase, CD62P positive rate and Annexin V positive rate. All the data were analyzed with SPSS24.0 software. One-way ANOVA was employed to compare the differences among three groups. In order to pairwise comparisons between means of multiple samples, Bonferroni method was applied. [Results] With the extension of storage time, the platelet count decreased and the Annexin V positive rate increased in the 3 groups, and the difference of the 3 groups was not statistically significant (P>0.05). The pH value decreased in the 3 groups, with values at day 1, 3, 5 and 7 of 7.44±0.13 vs 7.44±0.14 vs 7.41±0.11, 7.31±0.68 vs 7.43±0.23 vs 7.22±0.12, 7.30±0.15 vs 7.42±0.14 vs 7.17±0.12, 7.29±0.33 vs 7.26±0.18 vs 7.04 ± 0.12, respectively. The pH decline in the control group and experiment group 1 was minor, with no statistically significant difference, but experiment group 2 showed relatively larger decreases in day 5 and day 7, with statistically significant difference (P<0.05). LDH concentrate was elevated in 3 groups (mmol/L), with values at day 1,3,5 and 7 of 169.62±99.33 vs 105.80±150.71 vs 77.14±105.38, 225.10±112.86 vs 116.00±72.77 vs 94.42±88.74, 249.42±79.55 vs 119.00±53.51 vs 118.35±80.39, 253.34±86.95 vs 147.71±90.71 vs 124.68±128.68 respectively. Compared with the control group, the difference was statistically significant (P<0.05). Experimental group1 had the smallest increase; CD62P positive rate increased in 3 groups (%), with values at day 1, 3, 5 and 7 of 26.22±11.74 vs 23.48±12.48 vs 40.49±11.86, 41.29±8.36 vs 33.53±25.64 vs 50.42±22.36, 59.59±10.13 vs 36.39±23.10 vs 50.94±20.50, 72.92±15.44 vs 55.54±23.65 vs 61.89±18.82 respectively. Compared with the control group, the increase in experiment group1 was smaller, and the difference was statistically significant (P<0.05). [Conclusion] Platelet Addictive Solution ⅢM/plasma volume ratio of 6.5∶3.5 is superior to traditional plasma in maintaining platelet quality during the in vitro preservation period of platelets.

ObjectiveTo unveil the mechanism of Jianpi Huogu prescription （JPHGP） in ameliorating the dyslipidemia of steroid-induced osteonecrosis of the femur head （SONFH） by oxylipidomics combined with transcriptomics. MethodsSixty SD rats were assigned into normal， model， low-， medium-， and high-dose （2.5， 5， 10 g·kg^-1， respectively） JPHGP， and Jiangushengwan （1.53 g·kg^-1） groups. Lipopolysaccharide was injected into the tail vein at a dose of 20 μg·kg^-1 on days 1 and 2， and methylprednisolone sodium succinate was injected at a dose of 40 mg·kg^-1 into the buttock muscle on days 3 to 5. The normal group received an equal volume of normal saline. Drug administration by gavage began 4 weeks after the last injection， and samples were taken after administration for 8 weeks. Hematoxylin-eosin staining was conducted to reveal the histopathological changes of the femoral head， and the number of adipocytes， the rate of empty bone lacunae， and the trabecular area were calculated. Micro-computed tomography was used for revealing the histological and histomorphometrical changes of the femoral head. Enzyme-linked immunosorbent assay was employed to measure the serum levels of triglyceride （TG）， total cholesterol （TC）， low-density lipoprotein （LDL）， high-density lipoprotein （HDL）， apolipoprotein A1 （ApoA1）， and apolipoprotein B （ApoB）. At the same time， the femoral head was collected for oxylipidomic and transcriptomic detection. The differential metabolites and differential genes were enriched and analyzed， and the target genes regulating lipid metabolism were predicted. The predicted target proteins were further verified by molecular docking， immunohistochemistry， and Western blot. ResultsCompared with the normal group， the model group showcased thinning of the femoral head， trabecular fracture， karyopyknosis， subchondral cystic degeneration， increases in the number of adipocytes and the rate of empty bone lacunae （P<0.01）， a reduction in the trabecular area （P<0.01）， decreases in BMD， Tb.Th， Tb.N， and BV/TV， and increases in Tb.Sp and BS/BV （P<0.01）. Compared with the model group， the JPHGP groups showed no obvious thinning of the femoral head or subchondroidal cystic degeneration. The high- and medium-dose JPHGP groups presented declines in the number of adipocytes and the rate of empty bone lacunae， an increase in the trabecular area （P<0.05， P<0.01）， rises in BMD， Tb.Th， Tb.N， and BV/TV， and decreases in Tb.Sp and BS/BV （P<0.05， P<0.01）. Compared with the normal group， the model group showcased raised serum levels of TG， TC， LDL， and ApoB and lowered serum levels of HDL and ApoA1 （P<0.01）. Compared with the model group， the JPHGP groups had lowered serum levels of TG， TC， LDL， and ApoB （P<0.05， P<0.01） and a risen serum level of ApoA1 （P<0.05， P<0.01）. Moreover， the serum level of HDL in the high-dose JPHGP group increased （P<0.01）. A total of 19 different metabolites of disease set and drug set were screened out by oxylipidomics of the femoral head， and 119 core genes with restored expression were detected by transcriptomics. The enriched pathways were mainly concentrated in inflammation， lipids， apoptosis， and osteoclast differentiation. Molecular docking， immunohistochemistry， and Western blot results showed that compared with the normal group， the model group displayed increased content of 5-lipoxygenase （5-LO） and peroxisome proliferator-activated receptor γ （PPARγ） in the femoral head （P<0.01）. Compared with the model group， medium- and high-dose JPHGP reduced the content of 5-LO and PPARγ （P<0.05， P<0.01）. ConclusionJPHGP can restore the levels of oxidized lipid metabolites by regulating the 5-LO-PPARγ axis to treat SONFH in rats. Relevant studies provide experimental evidence for the efficacy mechanism of JPHGP in the treatment of SONFH.
