Platelets are small, anucleated cells generated by cytoplasmic fragmentation and shedding from mature megakaryocytes. Upon vascular stimulation or injury, platelets become activated and adhere to exposed vascular endothelial cells, ultimately forming thrombi to promote blood coagulation and wound healing. In recent years, increasing evidence from in-depth studies on platelet function has revealed that autophagy plays a crucial role in platelet production and functional performance. Autophagy is an intracellular process of material recycling and reuse, involving autophagosome formation, cargo degradation, and nutrient recycling, which facilitates the maintenance of homeostasis and defense against pathogen infection. Numerous studies have demonstrated that autophagy participates in the regulation of platelet production, activation, and aggregation, and is closely implicated in the pathogenesis of platelet dysfunction-related diseases such as immune thrombocytopenia. Additionally, platelet-rich plasma therapy, by modulating the autophagic process, has shown great potential in treating osteoarthritis and promoting diabetic foot wound healing. This review thoroughly explores the potential roles of autophagy in regulating platelet production and function, as well as in platelet-related diseases. Future research should focus on the molecular mechanisms of platelet autophagy, investigate its dynamic changes under different disease conditions, and explore how autophagy modulation can improve platelet function and treat related diseases. This will provide a theoretical foundation for developing novel therapeutic strategies and is expected to bring breakthroughs in the treatment of platelet-related diseases.

Hypertension ranks among the most prevalent chronic non-communicable diseases worldwide, with its prevalence rising steadily and exerting substantial impacts on the demographic composition of voluntary blood donors and the safety of blood supply. The eligibility of hypertensive individuals for safe blood donation and the relevant screening and management strategies have long remained controversial in transfusion medicine. This article systematically reviews the epidemiological characteristics of hypertension, donation-related physiological alterations and underlying risk mechanisms. By synthesizing evidence from international multicenter studies and regulatory practices across major nations, it conducts a comprehensive analysis of blood donation safety and donor admission criteria for hypertensive patients. Available evidence demonstrates that for hypertensives with well-stabilized blood pressure and no severe cardiac, cerebral or renal complications or target organ damage, the overall incidence of adverse reactions following blood donation is comparable to that in healthy donors, and no definitive correlation has been identified between blood pressure levels and vasovagal responses. Current mainstream international management frameworks are gradually shifting from screening reliant on a single blood pressure cutoff value toward an integrated strategy combining stratified risk classification and individualized dynamic assessment, with core focus on long-term blood pressure control, consistency of medication regimens and complication status. Meanwhile, emerging technologies including artificial intelligence, ambulatory blood pressure monitoring and wearable devices have opened innovative avenues for blood donation risk evaluation and full-cycle donor management. In light of existing clinical evidence, future efforts should further refine the multi-dimensional risk stratification system, facilitate the implementation of intelligent screening and continuous monitoring technologies, and scale up health education and follow-up management for hypertensive populations. Such measures aim to appropriately expand the pool of eligible blood donors while safeguarding donation safety, ultimately achieving coordinated improvement in blood safety and blood supply capacity.

Objective:To explore the role of glutathione peroxidase 4 (GPX4)-dependent ferroptosis in diclofenac-induced kidney injury.Methods:Human kidney tubular epithelial cells (HK-2 cells) were cultured and then divided into 3 groups: control group, diclofenac group, and iron death inhibitor ferrostatin-1 (Fer-1) group. The same amount of 1% Fer-1 (final concentration 10 μmol/L) and phosphate buffered saline was respectively added to cells in the Fer-1 group and the other 2 groups. After 48 hours of culture, diclofenac 200 μmol/L was added to cells in the diclofenac group and the Fer-1 group. The cell viability of each group was detected by cell counting kit-8 (CCK-8). The cell cycle, apoptosis and intracellular reactive oxygen species (ROS) levels were detected by flow cytometry. The levels of intracellular iron ion, lactate dehydrogenase (LDH), malondialdehyde (MDA) and GPX4 were detected by enzyme-linked immunosorbent assay. The expression level of GPX4 was detected by Western blotting method.Results:Compared with the control group, the cell viability and G1 phase cell percentage of the diclofenac group were significantly lower, and compared with the diclofenac group, those were significantly higher (all P<0.05). The apoptosis rate of diclofenac group was significantly higher than that of the control group ( P<0.05), but there was no significant difference in apoptosis rate between Fer-1 group and diclofenac group ( P>0.05). Compared with the control group, the intracellular ROS, iron content, LDH, and MDA levels were significantly higherin the diclofenac group, while the expression level of GPX4 was lower (all P<0.05). However, the ROS, iron content, LDH, and MDA levels in the Fer-1 group were lower than those in the diclofenac group, while GPX4 expression was higher than that in the diclofenac group (all P<0.05). Conclusion:Diclofenac can induce ferroptosis in HK-2 cells and inhibiting the ferroptosis can alleviate cell injury, suggesting that GPX4-dependent ferroptosis may be involved in kidney injury induced by diclofenac.

Objective:To compare the efficacy and safety of crisaborole ointment 2% versus pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged 2 years or older.Methods:A multicenter, randomized, open-label, controlled clinical trial was conducted. A total of 120 pediatric patients aged 2 - 17 years with mild to moderate atopic dermatitis were enrolled from departments of dermatology of 8 hospitals in China between March 2022 and February 2023. The participants were randomly assigned in a 1∶1 ratio to the crisaborole group and the pimecrolimus group, and received the treatment with crisaborole ointment 2% and pimecrolimus cream 1% respectively, twice a day for 4 weeks. Visits were scheduled at baseline/on day 1, as well as on days 8, 15, and 29. The primary efficacy outcome was the percentage of patients achieving the Investigator's Static Global Assessment (ISGA) success (defined as clear [0] or almost clear [1] on the ISGA scale, combined with ≥ 2‐grade improvement from baseline) on day 29. The secondary efficacy outcomes included changes in the Eczema Area and Severity Index (EASI) total scores from baseline to day 29, percentages of patients achieving ISGA improvement (defined as clear [0] or almost clear [1] on the ISGA scale), as well as changes in the Peak Pruritus Numerical Rating Scale (NRS) scores, Dermatology Life Quality Index (DLQI) /Infants' Dermatology Life Quality Index (IDLQI) /Children's Dermatology Life Quality Index (CDLQI) scores, and in the Dermatitis Family Impact (DFI) scores. Drug safety was evaluated according to the incidence of adverse events. Categorical data were compared using the chi-square test. Since measurement data did not follow a normal distribution, the rank sum test was used for comparisons of measurement data between groups.Results:A total of 106 children with mild to moderate atopic dermatitis were included in the per-protocol analysis set, with 52 in the crisaborole group (26 males and 26 females) and 54 in the pimecrolimus group (27 males and 27 females). There were no significant differences in age, disease duration, ISGA and EASI scores at baseline between the two groups (all P > 0.05). On day 29, 22 patients (42.31%) in the crisaborole group and 25 (46.30%) in the pimecrolimus group achieved ISGA success, with no significant difference between the two groups ( χ2 = 0.17, P = 0.68) ; 35 patients (67.31%) in the crisaborole group and 45 (83.33%) in the pimecrolimus group achieved ISGA improvement, also with no significant difference between the two groups ( χ2 = 3.68, P = 0.06) ; additionally, there were no significant differences in the EASI, pruritus NRS, DLQI/IDLQI/CDLQI, or DFI scores between the two groups (all P > 0.05). Adverse reactions to the two topical agents were mainly local reactions such as mild to moderate pain, itching, or worsening of itching, and no obvious systemic adverse reactions occurred. The incidence of drug-related adverse reactions was 46.15% (24 cases) in the crisaborole group and 37.04% (20 cases) in the pimecrolimus group, with no significant difference between the two groups ( χ2 = 0.91, P = 0.34) . Conclusion:The efficacy of crisaborole ointment 2% was comparable to that of pimecrolimus cream 1% in the treatment of mild to moderate atopic dermatitis in children aged ≥ 2 years, and it yielded early and rapid improvement in the quality of life of patients and their families, with good safety and tolerability profiles.

Objective:To compare the clinical characteristics of monogenic and non-monogenic early-onset inflammatory bowel disease (EO-IBD) in children and to explore the necessity of genetic analysis in EO-IBD research.Methods:A retrospective analysis of clinical data was conducted on 73 children diagnosed with EO-IBD at the Children's Hospital affiliated with Capital Institute of Pediatrics between January 2017 and December 2023. Genetic analysis was performed utilizing next-generation sequencing technology, with patients stratified into monogenic and non-monogenic groups based on the presence or absence of pathogenic mutations. Subsequently, a comparative analysis of clinical characteristics was conducted between these two cohorts of EO-IBD patients.Results:Among the 73 EO-IBD cases, 27 (37%) were diagnosed as monogenic IBD, and 46 (63%) as non-monogenic IBD. Compared to the non-monogenic group, the monogenic group had an earlier age of onset [1 (0.2, 3.0) months vs. 15 (4.1, 51.3) months, P < 0.001], with a higher incidence within the first month of life (70.4% vs. 13.0%, P < 0.001). Monogenic IBD cases were more likely to present with Crohn's disease (CD) phenotypes (88.9% vs. 52.2%, P = 0.003) and colonic involvement (L2) (91.7% vs. 62.5%, P < 0.001), but were less likely to present with non-penetrating, non-stricturing (B1) disease (87.5% vs. 95.8%, P = 0.019). Children in the monogenic group were more prone to severe malnutrition (74.1% vs. 21.3%, P < 0.001), perianal abscesses (40.7% vs. 8.7%, P < 0.001), perianal tags (22.2% vs. 0%, P = 0.004), fever (74.1% vs. 23.9%, P < 0.001), oral ulcers (44.4% vs. 6.5%, P < 0.001), and skin lesions (33.3% vs. 2.2%, P < 0.001). Regarding treatment, the monogenic group had higher usage of thalidomide (88.9% vs. 54.3%, P = 0.002) and hematopoietic stem cell transplantation (HSCT) (37.0% vs. 0, P < 0.001) and a higher mortality rate (22.2% vs. 2.2%, P = 0.017) . Conclusions:For children with IBD presenting at an early age, especially within the first month of life, and showing symptoms like fever, oral ulcers, skin lesions, severe malnutrition, and perianal disease, monogenic IBD should be considered. Genetic testing results can aid in guiding treatment decisions.
