Objective: To study the impact of sleep characteristics on myopia, among lower primary school students in Shanghai, so as to provide foundation for the prevention of the onset and development of myopia. Methods: A total of 636 students from the first and second grades of two primary schools in Jiading District, Shanghai, were selected through cluster random sampling for questionnaire surveys and ophthalmological examinations in October 2022. The Childrens Sleep Habits Questionnaire (CSHQ) was used to assess sleep quality at baseline. Ophthalmological examinations were conducted in October 2023(479), during which the students study time, screen time and outdoor activity time were monitored for twoweek, repeated twice. Generalized multivariable Logistic regression models and linear regression models were employed to examine the association between sleeprelated factors and myopia, as well as the strength of this association. Results: The baseline survey indicated a myopia prevalence of 18.58%, with 17.18% at followup. The average CSHQ total score was (51.58±4.44), and the average daily sleep duration was (9.43±4.84)h/d, with only 11.6% of participants meeting the recommended sleep sufficiency. Multivariable regression models indicated that insufficient sleep showed positive association with myopia (OR=1.64, 95%CI=1.05-2.56), while bedtime duration was significantly negative associated with myopia (OR=0.74, 95%CI=0.63-0.91, P＜0.05), adjusting for confounding factors. Inconsistency in bed rest time was a risk factor for myopia (OR=1.07, P<0.05), and the consistency of bed rest time, and wakeup time showed statistically significant correlations with SE (P<0.05). There was also statistically significant correlations between consistency in sleep time, bed rest time, and wakeup time with AL (P<0.05). Conclusions Insufficient sleep and bedtime duration are correlated with the onset and progression of myopia. It is critical to ensure sufficient sleep duration and regular sleep habits for children to reduce the occurrence of myopia in the primary school students.

Hereditary angioedema (HAE) is an autosomal dominant inherited disease characterized by recurrent and unpredictable episodes of subcutaneous or submucosal edema. These attacks could induce fatal risk when larynx is involved. The estimated prevalence of HAE is about 1 in 50 000. Due to its rarity and the diversity of clinical manifestations, HAE is known little by related physicians and misdiagnosis and mistreatment happens very often. Therefore, it is crucial to improve physicians′ understanding of HAE. To address this, a comprehensive management approach for the diagnosis and treatment of HAE have developed in our hospital. This approach includes intra-hospital multi-disciplinary treatment (MDT), collaboration with provincial network hospitals, patient education online and offline interacting with media propaganda. By implementing this approach, the diagnostic precision was significantly improved, the diagnostic time was significantly shortened, and the frequency of emergency interventions for severe laryngeal edema was significantly reduced. Additionally, the collection of data from HAE patients has provided valuable clinical insights for the diagnosis and treatment of HAE in China.

Objective:This study aims to evaluate the safety and effectiveness of gilteritinib (Gilt) -based combination therapy bridging allo-HSCT for FLT3-ITD + R/R AML. Additionally, it aims to assess the impact of Gilt maintenance therapy on the prognosis of patients after allo-HSCT. Methods:The clinical data of 26 patients with FLT3-ITD + R/R AML treated at the First Affiliated Hospital of Soochow University from August 2019 to January 2023 were retrospectively analyzed. The analysis included an assessment of the composite complete remission rate (CRc), overall survival (OS) time, disease-free survival (DFS) time, and adverse events experienced by all enrolled patients. Results:A total of 26 patients with FLT3-ITD + R/R AML were enrolled, including 14 men and 12 women with a median age of 38 (18-65) years. A total of 18 cases were refractory, and eight cases were relapsed. The curative effect evaluation conducted between 14 and 21 days showed that the complete remission (CR) rate was 26.9% (7/26), the CR with hematology incomplete recovery was 57.7% (15/26), and the partial response (PR) rate was 7.7% (2/26). The CRc was 84.6% (22/26), and the minimal residual disease (MRD) negativity rate was 65.4%. The 12 month cumulative OS rate for all patients was 79.0%, and the 24 month cumulative OS rate was 72.0%. The median OS time was not determined. The median follow-up time was 16.0 months. Among the patients who responded to treatment, the 12 month cumulative DFS rate was 78.0%, and the 24 month cumulative DFS rate was 71.0%. The median DFS time was not determined. Patients who received allo-HSCT had a median OS time that was significantly longer than those who did not receive allo-HSCT (3.3 months, 95% CI 2.2-4.3 months, P=0.005). The median OS time of patients with or without Gilt maintenance therapy after allo-HSCT was not determined, but the OS time of patients with Gilt maintenance therapy after allo-HSCT treatment was longer than that of patients without Gilt maintenance therapy after allo-HSCT treatment ( P=0.019). The FLT3-ITD mutation clearance rate in this study was 38.5%, and the median OS time of patients with FLT3-ITD mutation clearance was not determined but was significantly longer than the median OS of patients without FLT3-ITD mutation clearance (15.0 months; P=0.018). The most common grade 3 and above hematological adverse events of Gilt-based combination therapy included leukopenia (76.9%), neutropenia (76.9%), febrile neutropenia (61.5%), thrombocytopenia (69.2%), and anemia (57.7%). One patient developed differentiation syndrome during oral Gilt maintenance therapy after allo-HSCT treatment, but his condition improved after treatment. Conclusion:The Gilt-based combination therapy is highly effective in treating FLT3-ITD + R/R AML. It demonstrates a high CRc, MRD negativity rate, and rapid onset, leading to a significant improvement in patients' survival. Furthermore, the clearance rate of FLT3-ITD mutation is notably high. Additionally, implementing bridging allo-HSCT and Gilt maintenance therapy after allo-HSCT treatment has considerably enhances patients' survival. Closely monitoring and managing any adverse event that may occur during treatment are crucial.

Objective:To investigate the efficacy and safety of protein A immunoadsorption (PAIA) combined with rituximab (RTX) in highly sensitized patients who underwent haplo-hematopoietic stem cell transplantation (haplo-HSCT) .Methods:The clinical data of 56 highly sensitized patients treated with PAIA and RTX before haplo-HSCT at the First Affiliated Hospital of Soochow University and Soochow Hopes Hematonosis Hospital between March 2021 and June 2023 were retrospectively analyzed. The number of human leukocyte antigen (HLA) antibody types and the mean fluorescence intensity (MFI), humoral immunity, adverse reactions during adsorption, and survival within 100 days before and after adsorption were measured.Results:After receiving the PAIA treatment, the median MFI of patients containing only HLA Ⅰ antibodies decreased from 7 859 (3 209-12 444) to 3 719 (0-8 275) ( P<0.001), and the median MFI of HLA Ⅰ+Ⅱ antibodies decreased from 5 476 (1 977-12 382) to 3 714 (0-11 074) ( P=0.035). The median MFI of patients with positive anti-donor-specific antibodies decreased from 8 779 (2 697-18 659) to 4 524 (0–15 989) ( P<0.001). The number of HLA-A, B, C, DR, and DQ antibodies in all patients decreased after the PAIA treatment, and the differences were statistically significant (A, B, C, DR: P<0.001, DQ: P<0.01). The humoral immune monitoring before and after the PAIA treatment showed a significant decrease in the number of IgG and complement C3 ( P<0.001 and P=0.002, respectively). Forty-four patients underwent HLA antibody monitoring after transplantation, and the overall MFI and number of antibody types decreased. However, five patients developed new antibodies with low MFI, and nine patients continued to have high MFI. The overall survival, disease-free survival, non-recurrent mortality, and cumulative recurrence rates at 100 days post-transplantation were 83.8%, 80.2%, 16.1%, and 4.5%, respectively. Conclusions:The combination of PAIA and RTX has a certain therapeutic effect and good safety in the desensitization treatment of highly sensitive patients before haplo-HSCT.

Objective:To investigate the role of p-AKT-mTOR-P70S6K signaling pathway in radiation therapy for polyploid cervical cancer cells.Methods:Human cervical cancer HeLa cell lines were selected and HeLa cells were radiated under 7 Gy of 6 MV X-ray. The morphological changes of the cells were observed with an inverted microscope on day 5 after radiation induction. All cells were divided into the 7 Gy group (7 Gy X-ray radiation but not transfected polyploidy HeLa cells) and the control group (the non-radiation-induced and not transfected HeLa cells). In addition, the plasmid carrying pcDNA3 negative control sequence and the plasmid carrying pcDNA3-TT-AKT sequence were transfected into HeLa cells, respectively, which were induced by 7 Gy X-ray radiation after 48 h of transfection, and then they were recorded as the pcDNA3 + 7 Gy group and the pcDNA3-TT-AKT + 7 Gy group. Cell proliferation ability was detected by using CCK-8 assay, cell cycle was detected by using flow cytometry, cell apoptosis was detected by using mitochondrial membrane potential assay, the relative expression levels of cell proliferation, cell cycle, apoptosis and autophagy related proteins were tested by using Western blot.Results:Most of the normal HeLa cells in the 7 Gy group died on day 5 after radiation induction, and only a few surviving cells increased in size with multiple nuclei. The results of Western blot showed that the relative expression levels of p-AKT, p-mTOR and p-P70S6K in HeLa cells of the 7 Gy group were lower than those of the control group (all P < 0.05). CCK-8 assay showed that the absorbance ( A) values were 0.45±0.06, 0.65±0.06 after 48 h of culture and 0.75±0.05, 1.05±0.02 after 72 h of culture, respectively in the pcDNA3 + 7 Gy group and the pcDNA3-TT-AKT + 7 Gy group, and the differences were statistically significant (all P < 0.05), and the A values in the pcDNA3-TT-AKT + 7 Gy group were all higher than those in the pcDNA3 +7 Gy group. Flow cytometry results showed that the proportion of cells was (29.2±3.6)%, (26.7±1.7)% in G 0/G 1 phase and (29.6±1.6)%, (30.3±0.6)% in G 2/M phase, respectively in the pcDNA3 + 7 Gy group and the pcDNA3-TT-AKT + 7 Gy group, and the differences were not statistically significant (all P > 0.05); the proportion of cells in S phase was (10.2±0.9)% and (14.6±1.5)%, respectively in the pcDNA3 + 7 Gy group and the pcDNA3-TT-AKT + 7 Gy group, and the differences were statistically significant ( t = 2.86, P = 0.043). Mitochondrial membrane potential assay showed that the green fluorescence proportion was (23.1±2.5)% and (14.3±1.9)%, respectively in the pcDNA3 + 7 Gy group and the pcDNA3-TT-AKT + 7 Gy group, and the different was statistically significant ( t = 4.82, P = 0.009). Western blot results showed that the relative expression level of p-cdc25c (Ser216) in the pcDNA3-TT-AKT+7 Gy group was higher than that in the pcDNA3+7 Gy group ( P < 0.001); and the relative expression levels of Bak and LC3-Ⅱ/Ⅰ in the pcDNA3-TT-AKT+7Gy group were lower than those in the pcDNA3 +7 Gy group, respectively (all P < 0.05). Conclusions:The p-AKT-mTOR-P70S6K signaling pathway may be involved in the regulation of radiation-induced polyploidy HeLa cell proliferation, cell cycle and cell apoptosis.

Objective:To investigate the characteristics related to proliferation, migration and invasion of radiation-induced polyploid colon cancer SW1116 cells and their progeny.Methods:Colon cancer SW1116 cells were conventionally cultured in Leibovitz's L-15 medium containing 10% fetal bovine serum. SW1116 cells at logarithmic growth stage were irradiated with 7 Gy X-ray, and the morphological changes of the cells were observed by inverted microscope on days 3, 5, 10 and 19 after radiation induction. According to the morphological changes of the cells, the cells at day 3 after radiation induction were labeled as polyploid giant cancer cell (PGCC) group, and the cells at day 19 were recorded as PGCC progeny group. SW1116 cells without radiation induction were used as control group. Flow cytometry was used to detect cell ploidy in the control, PGCC and PGCC progeny groups, CCK-8 assay was used to detect the proliferation ability of the three groups, cell migration and invasion abilities of the three groups were detected by cell scratch assay and Transwell assay, and Western blotting was used to detect the expressions of cell cycle and proliferation-related proteins and epithelial-mesenchymal transition (EMT) marker N-cadherin (N-cad) in the three groups.Results:The volume of SW1116 cells gradually became larger on days 3, 5 and 10 after radiation induction, and returned to normal on day 19. The proportions of polyploid (DNA content >4N) cell subsets in the control group, PGCC group and PGCC progeny group were (2.3±1.1)%, (23.1±8.1)% and (3.2±0.5)%, the difference was statistically significant ( F = 18.52, P < 0.05), and the proportion of polyploid cell subpopulations in the PGCC group was higher than that in the control group ( t = 5.38, P < 0.01), but the differences between the PGCC progeny group and the control group were not statistically significant ( t = 0.22, P > 0.05). After 72 h of culture, the cell proliferation rates of the control, PGCC and PGCC progeny groups were (100.0±4.1)%, (73.5±0.7)% and (123.9±3.5)%, and the difference was statistically significant ( F = 190.27, P < 0.001). After 48 h of cell scratching, the scratch healing rates in the control, PGCC and PGCC progeny groups were (38.0±2.7)%, (41.5±4.0)% and (63.7±4.2)%, and the difference was statistically significant ( F = 43.05, P < 0.001). After 24 h of culture, the number of invasive cells in the control, PGCC and PGCC progeny groups was 12.9±1.2, 3.4±0.6 and 23.7±1.5, and the difference was statistically significant ( F = 63.64, P < 0.001). The expression levels of cell cycle-related proteins P-cdc25c, cdc25c and cdc2 in the PGCC group were lower than those in the control group (all P < 0.05), and the expression levels of transcription factor-related proteins E2F-2, E2F-3 and EMT marker N-cad were downregulated compared with the control group (all P < 0.05); the expression levels of P-cdc25c, cdc25c, cdc2, E2F-2, E2F-3 and N-cad proteins in the PGCC progeny group were higher than those in the control group (all P < 0.05). Conclusions:Radiation can induce colon cancer SW1116 cells to produce polyploid, which may then generate daughter cells through asymmetric mitosis and gain new life, and then promote the recurrence and metastasis of colon cancer.
