Objective: To explore the correlation between the composition of bone marrow lymphocyte subsets and the clinical attributes observed in de novo AML patients, as well as their influence on prognosis. Methods: A detailed study was carried out on a cohort of 191 de novo acute myeloid leukemia patients who were admitted to our medical center between October 2022 and September 2024. In addition, a group of 24 patients with iron deficiency anemia individuals was carefully chosen as the control cohort. The proportions of lymphocyte subsets within the bone marrow of de novo AML patients were analyzed. Furthermore, an in-depth analysis was performed to investigate the association between the expression levels of these subsets in de novo AML patients and their clinical attributes, as well as their prognostic implications. Results: The proportion of CD19 and CD56 lymphocytes within the bone marrow of de novo AML patients significantly diminished compared to the control cohort (8.5% vs 13.2% P<0.05, and 15.5% vs 18.0%, P<0.05). Conversely, no significant discrepancies were observed in the CD3 , CD3 CD4 , and CD3 CD8 lymphocyte percentages between the AML patients and control group (71.7% vs 72.1%, 32.5% vs 33.7% and 32.8% vs 35.7%, P>0.05). When analyzing the relationships between lymphocyte subsets within the bone marrow of de novo patients and their respective clinical characteristics, patients aged 60 years and above exhibited diminished percentages of CD3 CD8 lymphocytes in the bone marrow compared to their younger counterparts (31.6% vs 34.1%, P<0.05), while the CD56 lymphocyte subsets demonstrated an increased prevalence (17.2% vs 14.4%, P<0.05). Furthermore, patients with leukocytosis (WBC≥100×10 /L) presented lower levels of CD3 and CD3 CD4 lymphocytes in the bone marrow compared with those without it (65.3% vs 72.9% P<0.05, and 28.9% vs 33.2%, P<0.05), respectively. The AML1-ETO fusion gene-positive cohort exhibited a higher prevalence of CD3 CD8 lymphocytes in the bone marrow than in the negative group (38.2% vs 32.3%, P<0.05), whereas the FLT3-ITD mutation-positive group presented a decreased prevalence of CD56 lymphocytes compared with the negative group (12.4% vs 16.8%, P<0.05). In addition, the NPM1 mutation-positive group demonstrated lower levels of CD3 CD8 lymphocytes in the bone marrow than in the negative group (29.1% vs 33.3%, P<0.05). Variables such as tumor protein p53(TP53) mutation positive, the absence of hematopoietic stem cell transplantation, and CD3 CD4 lymphocyte proportions below 25% were identified as independent adverse prognostic indicators for AML patients (P<0.05). Conclusion: The pathogenesis of AML is closely associated with an imbalance in bone marrow lymphocyte subsets. The FLT3-ITD mutation potentially contributes to the dysregulation of CD56 lymphocyte subset expression. The AML1-ETO fusion gene and NPM1 mutation are implicated in the abnormal expression of CD3 CD8 lymphocytes within the bone marrow. Moreover, the percentage of CD3 CD4 lymphocytes in the bone marrow serves as a prognostic factor for de novo AML patients.

Objective: To construct a 5G unmanned aerial vehicle (UAV) airport platform for blood transportation and explore its feasibility and advantages within the blood emergency support system. Methods: Based on 5G high-speed network transmission technology, a UAV management system was designed to achieve a closed-loop management of the entire transportation process, including blood distribution, route information, flight status, emergency dispatch, hospital reception, real-time temperature monitoring, and video surveillance. Integrated with an open UAV airport, the first "5G UAV Blood Transportation Intelligent Airport Platform" was established. Results: At present, the platform has settled in 2 sets of UAV systems, established 17 routes, and carried out regular UAV blood transportation services for 15 hospitals. From January 1, 2024 to June 30, 2025, a total of 12 134 sorties were completed, with a total transported blood weight of 7 692.38 kg, including 25 500 units of red blood cells, 3 824.5 units of platelets, 1 350 370 mL of plasma, and 10 810 units of cryoprecipitate. Compared to land transportation, UAV delivery saved an average of 46.8 minutes during rush hours (maximum: 89.3 minutes) and an average of 32.3 minutes during non-rush hours (maximum: 59.1 minutes). In terms of the quality of UAV blood transportation, the temperature of suspended red blood cells was between 4 and 8℃, that of platelets was between 20 and 24℃, and that of plasma was below 0℃. No damage has occurred so far. Conclusion: The UAV blood transportation platform can stably provide blood delivery services during both routine and emergency conditions, ensuring timely blood delivery and stable blood quality.

Objective:To explore the effects of tyrosine kinase inhibitors (TKI) on SARS-CoV-2 infection, the related symptoms, and recovery in patients with chronic myeloid leukemia (CML) during the SARS-CoV-2 epidemic.Methods:A retrospective case series study was conducted. The information including general data and SARS-CoV-2 infection of 319 CML patients treated in the First Affiliated Hospital of Soochow University from January 2021 to December 2021 and 547 co-residents during the SARS-CoV-2 epidemic was collected by telephone follow-up from December 2022 to January 2023. The differences in clinical characteristics, infection rate, symptom severity, and recovery time of the SARS-CoV-2 between CML patients and their co-residents, between patients whether getting vaccine for SARS-CoV-2, between patients whether receiving TKI and among CML patients receiving different types of TKI were compared. The multivariate logistic regression analysis was used to analyze the factors influencing the infection rate, symptom severity, and recovery time of SARS-CoV-2.Results:The median age [ M ( Q1, Q3)] of CML patients was 46 years (36 years, 57 years) and all 319 CML patients included 188 (59.0%) males and 131 (41.0%) females; the median age of co-residents of CML patients was 41 years (22 years, 55 years), and all 547 co-residents included 266 (48.6%) males and 281 (51.4%) females. There were statistically significant differences in age, gender, vaccination against SARS-CoV-2 or not, infection rate [83.7% (267/319) vs. 90.5% (495/547)], distribution of symptomatic patients at different severity levels (mild, moderate, severe, and fatal), and recovery time [7 d (5 d, 14 d) vs. 6 d (2 d, 8 d)] between CML patients and co-residents (all P < 0.05). There were statistically significant differences in age, gender, SARS-CoV-2 infection rate, distribution of symptomatic patients at different severity levels and recovery time between CML patients (143 cases) and their co-residents (517 cases) who received the SARS-CoV-2 vaccine (all P < 0.05); there were no statistically significant differences in age, gender, infection rate, distribution of symptomatic patients at different severity levels and recovery time between vaccinated and unvaccinated CML patients with SARS-CoV-2 vaccine (all P > 0.05). There were 297 (93.1%) CML patients who took TKI and 22 patients who did not take TKI. There were no statistically significant differences in age and gender distribution between patients taking TKI and those not taking TKI (all P > 0.05). The infection rate of SARS-CoV-2 in patients taking TKI was lower than that of patients not taking TKI [82.5% (245/297) vs. 100.0% (22/22)], and the difference was statistically significant ( P = 0.032); however, there were no significant differences in distribution of symptomatic patients at different severity levels and recovery time between patients taking TKI and those not taking TKI (all P > 0.05). The results of multivariate logistic regression analysis showed that TKI therapy was an independent protective factor for SARS-CoV-2 infection in CML patients (taking TKI vs. not taking TKI: OR = 1.970, 95% CI: 1.093-3.554, P = 0.024), and was an independent risk factor for severe symptoms of SARS-CoV-2 infection (assigning mild, moderate, severe and fatal levels the value of 0, 1, 2, 3; OR = 0.042, 95% CI: 0.004-0.421, P = 0.007) and recovery time exceeding 7 d (> 7 d vs. ≤ 7 d, OR = 0.649, 95% CI: 0.426-0.988, P = 0.044). The third TKI therapy was given in 1 patient, and there were no statistically significant differences in SARS-CoV-2 infection rate, the symptoms at different severity levels and recovery time > 7 d between CML patients receiving first generation TKI (63 cases) and those receiving second generation TKI (77 cases) who were vaccinated against SARS-CoV-2 (all P > 0.05). Conclusions:TKI can reduce the infection rate of SARS-CoV-2 in CML patients, but will aggravate the severity of symptoms and prolong the recovery time. TKI types may have no impact on whether infected with SARS-CoV-2, the severity level of symptoms after infection and recovery time.

Objective: To analyze the associations among body mass index (BMI), learning screen/gaming screen exposure and executive function in preschool children in Anhui Province, so as to provide a basis for promoting the development of executive function in preschool children. Methods: In June 2022, a stratified cluster sampling and convenience sampling methods were used to survey 3 534 mothers of preschool children in Wuhu City, Luan City, and Fuyang City, Anhui Province. The Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) was used to assess the preschool childrens executive function abnormalities. Binary Logistic regression was conducted to examine the relationships among BMI, learning screen/gaming screen exposure, and their combined effects on executive function abnormalities. Results: The detection rate of abnormal executive function in preschool children was 9.65%. Logistic regression analysis showed that after adjusting for the confounding factors such as pregnancyinduced hypertension, primary caregivers, family per capita monthly income and family structure, the risk of abnormal executive function of children in overweight/obesity group and high learning screen/gaming screen exposure group increased significantly (overweight/obesity:OR=1.78, 95%CI=1.31-2.42, learning screen exposure:OR=1.48, 95%CI=1.18-1.86, gaming screen exposure:OR=1.50, 95%CI=1.18-1.91,P<0.05). Compared with children with normal BMI and low learning screen/gaming screen screen exposure, those with both overweight/obesity and high learning screen/gaming screen exposure had a significantly greater risk of executive function abnormalities (OR=2.07, 95%CI=1.29-3.31; OR=2.42, 95%CI=1.59-3.68,P<0.05). Conclusions Overweight/obesity and high learning screen/gaming screen exposure are important risk factors for executive function abnormalities in preschool children. Therefore, actively guiding preschool children to develop healthy life habits to promote the normal development of their executive functions is essential.

AIM: To explore the effect of lncRNA SNHG6 on injury of human retinal microvascular endothelial cells(hRMECs)induced by high glucose and its possible mechanism.METHODS: The D-glucose-induced hRMECs were used to establish normal glucose(NG)and high glucose(HG)cell injured model. In the HG group, the hRMECs were cultured in DMEM medium at a concentration of 25 mmol/L D-glucose for 24 h, while in the NC group, they were cultured in DMEM medium at a concentration of 5.5 mmol/L D-glucose; according to experimental design, si-NC, si-SNHG6, si-SNHG6 and anti-miR-NC and si-SNHG6 and anti-miR-186-5p were transfected into hRMECs, and then incubated at a concentration of 25 mmol/L D-glucose for 24 h, with HG+si-NC group, HG+si-SNHG6 group, HG+si-SNHG6+anti-miR-NC group and HG+si-SNHG6+anti-miR-186-5p group marked, respectively. The quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression of lncRNA SNHG6 and miR-186-5p; dual-luciferase reporter assay was used to detect the targeting relationship; MTT assay and flow cytometry were used to detect the cell proliferation and apoptosis, respectively; enzyme linked immunosorbent assay(ELISA)was used to detect the levels of IL-1β, TNF-α, IL-8, IL-10; testing kits were used to detect activity of SOD and level of MDA; the Western blot was used to detect the protein expression of cleaved-caspase3, Bax and Bcl-2.RESULTS: The lncRNA SNHG6 expression increased in the HG group, while miR-186-5p expression decreased(both P<0.05). There was target binding of lncRNA SNHG6 with miR-186-5p. After the transfection of si-SNHG6, cell inhibition rate, apoptosis rate, cleaved-caspase3, Bax protein levels, IL-1β, TNF-α, IL-8 contents, and MDA activity were decreased(P<0.05), while Bcl-2 protein, IL-10 contents, and SOD activity were increased(P<0.05). Co-transfection of si-SNHG6 and anti-miR-186-5p increased cell proliferation inhibition rate, apoptosis rate, cleaved-caspase3, Bax, IL-1β, TNF-α, IL-8, and MDA(P<0.05), but decreased Bcl-2, IL-10 and SOD(P<0.05).CONCLUSION: Interfering with lncRNA SNHG6 could inhibit cell apoptosis, inflammation and oxidative stress of high-glucose- induced hRMECs by elevating the expression of miR-186-5p.

Objectives Objectives To investigate how the imbalance of innate lymphoid cells (ILCs)in the peripheral blood of patients with lung adenocarcinoma affects the balance of downstream mononuclear macrophages and T helper (Th) cells, and to identify the impact of the imbalance of ILCs on the immune status and prognosis of lung adenocarcinoma. Methods The peripheral blood of 20 patients with lung adenocarcinoma and normal controls were collected. The percentage of ILCs, mononuclear macrophages and T lymphocyte in peripheral blood were analyzed by flow cytometry. The characteristic cytokine secretion levels of various types of immune cells in peripheral blood were detected by real-time fluorescence quantitative PCR. Results Compared with the normal controls, the proportion of M2 mononuclear macrophages, ILC1 and ILC2 in patients with lung adenocarcinoma was up-regulated, while the proportion of M1 mononuclear macrophages, CD4⁺ T and CD8⁺ T was down-regulated. The mRNA expression of related cytokines of M1 mononuclear macrophages and ILC1 were decreased; while the mRNA expression of related cytokines of M2 mononuclear macrophages and ILC2 were increased. Along with the decreased CD4⁺T cells-associated cytokine T-bet mRNA expression, and the increased GATA3 mRNA expression. Moreover, the expression of PD-1 in CD8⁺ T cells was also up-regulated. Conclusion The imbalance of ILCs in peripheral blood of patients with lung adenocarcinoma promotes the imbalance of mononuclear macrophages and Th cells, which altogether maintains the immunosuppression in patients with lung adenocarcinoma, and promotes the development of lung adenocarcinoma.

OBJECTIVE: To analyze the clinical characteristics of patients with emergency in-hospital cardiac arrest (IHCA) in Kashgar, Xinjiang Uygur Autonomous Region and the factors affecting the success rate of cardiopulmonary resuscitation. METHODS: Retrospectively selected patients who had cardiac arrest and cardiopulmonary resuscitation in the emergency department of the People's Hospital of 6 counties and cities in Kashgar area from January 2019 to January 2022. The clinical data of all patients were collected, including gender, age, major underlying diseases, the beginning and duration of resuscitation, the number of electric defibrillation acute physiology and chronic health evaluation II (APACHE II). According to whether the resuscitation was successful, all patients were divided into successful resuscitation group and failed resuscitation group. The clinical characteristics of the two groups were compared. Then, the influencing factors of the success rate of cardiopulmonary resuscitation in IHCA patients were analyzed by binary Logistic regression. RESULTS: A total of 1 376 patients were enrolled, including 1 117 cases of failed resuscitation and 259 cases of successful resuscitation. The success rate of resuscitation was 18.82%. Compared with the resuscitation failure group, the patients in the successful resuscitation group were younger (age: 49.10±20.99 vs. 58.44±18.32), the resuscitation start time was earlier [resuscitation start time ≤ 5 minutes: 76.45% (198/259) vs. 66.61% (744/1 117)], the proportion of cardiovascular and cerebrovascular diseases was lower [cardiovascular disease: 49.42% (128/259) vs. 58.19% (650/1 117), cerebrovascular disease: 17.37% (45/259) vs. 21.58% (241/1 117)], the number of electric defibrillation was lower [times: 0 (0, 2) vs. 1 (0, 1)], the proportion of endotracheal intubation was more [80.31% (208/259) vs. 55.60% (621/1 117)], APACHE II score was lower (13.75±8.03 vs. 17.90±4.63), and the difference was statistically significant (all P < 0.01). Binary Logistic regression analysis showed that age, start time of resuscitation, ventilation mode and APACHE II score were protective factors affecting the success rate of cardiopulmonary resuscitation in patients with emergency IHCA [age: odds ratio (OR) = 0.982, 95% confidence interval (95%CI) was 0.973-0.991, P < 0.001; resuscitation start time ≤ 5 minutes: OR = 0.629, 95%CI was 0.409-0.966, P = 0.034; tracheal intubation assisted ventilation: OR = 0.243, 95%CI was 0.149-0.397, P < 0.001; low APACHE II score: OR = 0.871, 95%CI was 0.836-0.907, P < 0.001], while underlying diseases (cardiovascular diseases) are a risk factor affecting the success rate of cardiopulmonary resuscitation (OR = 1.190, 95%CI was 1.015-1.395, P = 0.036). CONCLUSIONS Age, resuscitation start time, ventilation mode, APACHE II score and major underlying diseases (cardiovascular diseases) have a greater impact on the success rate of resuscitation in IHCA patients. The above factors are conducive to improving or formulating more effective rescue strategies for IHCA patients, so as to achieve the purpose of improving the success rate of clinical treatment.
