AIM: To study the effects of oxidative modification lipoproteins on blood coagulation and fibrino (lysis) in vitro. METHODS: Normal human plasma VLDL, LDL and HDL, which were isolated by density gradient ultracentrifugation method, were oxidatively modified by Cu~(2+) and HOCl method. N-VLDL, Ox-VLDL, N-LDL, Ox-LDL, N-HDL, Ox-HDL were added to the reaction system which consisted of mixed fresh normal plasma respectively, prothrombin time (PT), activated partial thrombplastin time (APTT), plasminogen activator inhibitor 1 (PAI-1), tissue plasminogen activator (t-PA) and platelet aggregation were measured according to the direction of the kits. RESULTS: The relative electrophoretic mobility (REM), absorbance at 234nm and TBARS of oxidized VLDL, LDL and HDL mediated by HOCl or Cu~(2+) were significantly higher than that of the control group (P

With the widespread application of diving technology, the safety of long-term diving has become a research focus. Research on the chronic health effects of long-term diving on divers mainly focuses on the respiratory system, circulatory system, nervous system, skeletal system, urinary system, as well as psychological health and sleep. Long-term diving can lead to increased lung capacity, thickening of nasal mucosa, myocardial hypertrophy, changes in heart rhythm, and hearing loss in divers. The impact of long-term diving on health is influenced by diving exposure index such as diving mode, maximum diving depth, underwater stay time, diving frequency, and number of dives, as well as individual factors such as years of diving experience, age, and medical history of divers. However, research on the effects of diving on health are inconsistent, and the potential mechanisms of health damage are unclear. Future large-scale research should be conducted under strict experimental conditions and with standardized inclusion criteria for subjects. Establishing a scientific and systematic assessment method for decompression is crucial for studying the chronic health effects of divers and enhancing understanding of relevant mechanisms to promote the development of diving industry and sport.

Objective:
To explore the genetic basis for a patient with autism.
Methods:
High-throughput sequencing was carried out to detect copy number variations in the patient.
Results:
DNA sequencing found that the patient has carried a 0.11 Mb deletion in distal 2p16.3 spanning from genomic position 50 820 001 to 50 922 000, which resulted removal of exon 6 and part of intron 7 of the NRXN1 gene. The same deletion was not found his parents and brother.
Conclusion
Partial deletion of the NRXN1 gene may underlie the disease in this patient.

Objective:To explore the efficacy and safety of whole-brain low-dose radiotherapy(LDRT)combined with PD-1 inhibitor sin-tilimab and intrathecal pemetrexed(IP)for the treatment of refractory non-small cell lung cancer(NSCLC)with leptomeningeal metastases(LM).Methods:Retrospective analysies were was performed on eight NSCLC patients with LM at the West China Hospital of Sichuan Uni-versity from December 2022 to May 2024.Among the eight patients,there were four were males and four were females,with a median age of 49 years(rangeing,between 34 to 58 years).All patients were treated with whole-brain LDRT combined with immune checkpoint inhibit-or(ICI)and intrathecal chemotherapy regimens,and the therapeutic efficacy was evaluated according to the Response Assessment in Neuro-Oncology(RANO)criteria and the Karnofsky physical status(KPS)score.Adverse reactions were assessed according to the Common Criteria for the Evaluation of Adverse Events(CTCAE version 5.0).Survival analysis was performed using the Kaplan-Meier method.The classification proportion of cerebrospinal fluid subsets before and after treatment was analyzed using by single-cell sequencing,and the differential ana-lysis of gene expression in parallel cells was performed.Results:The best clinical treatment effects in eight patients were were evaluated us-ing the RANO criteria:five patients(62.5%)were evaluated as improved and three(37.5%)as stable.The median KPS score of the eight pa-tients was 30(20-50)before treatment,which was significantly improved to 60(40-90)after treatment(P=0.000 9).The remission rate of neurological symptoms was 100%(8/8)in eight patients.The median neurological progression-free survival(NPFS)was 12 months.The res-ults of single-cell sequencing in CSF of patientss(P1)showed that the proportion of T cells in the patient samples after whole-brain LDRT treatment was significantly higher than that before treatment(6.08%vs.68.87%),and the proportion of tumor cells was significantly lower(12.92%vs.0.6%).The differential analysis of gene expression showed that CCL5 and CXCL13 were significantly upregulated in T cells of CSF after WB-LDRT treatment.Conclusions:The combination of whole-brain LDRT with ICI and IP in the treatment of NSCLC with LM can signific-antly alleviate neurological symptoms,improve quality of life and prolong the NPFS of patients,which is a safe and effective treatment.
