ObjectiveTo explore the potential mechanism of Xiaoqinglongtang(XQL) in the prevention and treatment of high altitude pulmonary edema(HAPE) by network pharmacology, molecular docking, and molecular dynamics simulation, and to verify it by in vivo animal model. MethodsIn this study, the active ingredients, drug targets, and HAPE-related targets of XQL were collected from BATMAN-TCM, GeneCards, and Online Mendelian Inheritance in Man(OMIM) databases. The protein-protein interaction(PPI) network was constructed by using intersection targets, and the core targets were screened and visualized by Cytoscape software. Functional annotation and pathway analysis of the intersection targets were performed by gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) functional enrichment. AutoDock and GROMACS were used to evaluate the binding ability of active ingredients to key targets. In the experimental verification part, a mouse model of HAPE induced by hypobaric hypoxia(simulated 6 000 m altitude for 48 h) was established. The control effect was evaluated by hematoxylin-eosin(HE) staining, lung tissue water content, lung tissue wet/dry weight ratio, real-time quantitative polymerase chain reaction(Real-time PCR) detection of gene expression levels, and immunohistochemistry and Western blot detection of key protein expression. ResultsA total of 355 active ingredients of XQL, 2 142 targets, 716 HAPE-related targets, and 236 intersection targets were obtained by network pharmacology analysis. Key core targets such as interleukin (IL)-6, tumor necrosis factor (TNF), protein kinase B1 (Akt1), and hypoxia-inducible factor-1α (HIF-1α) were screened. The results of GO analysis of common targets involved 738 biological processes(BP), 72 cellular components(CC), and 135 molecular functions(MF). KEGG analysis effectively enriched two important signaling pathways: Phosphoinositol 3-kinase (PI3K)/Akt and HIF-1α. The results of molecular docking and molecular dynamics simulation showed that the screened active ingredients had good binding ability with key targets. In the HAPE model induced by hypobaric hypoxia(6 000 m, 48 h), the lung tissue water content, lung tissue wet/dry weight ratio, and pathological injury score of the model group were significantly increased(P<0.01), accompanied by exudation of a large number of red blood cells in the alveoli and alveolar interstitium, a significant increase in inflammatory cells, a significant widening of the alveolar septum, and mutual fusion between the alveoli. The XQL administration group significantly improved the above pathological changes(P<0.01). The results of inflammatory factor expression showed that compared with the control group, the model group showed significantly up-regulated expression of TNF-α, IL-6, and IL-1β in the lung tissue(P<0.01). Compared with the model group, the XQL administration group had significantly decreased expression of inflammatory factors(P<0.05, P<0.01). The mRNA expression of key pathway related genes PI3K, Akt1, mammalian target of rapamycin(mTOR), and HIF-1α was significantly increased in the model group(P<0.01), and decreased in a concentration-dependent manner after XQL administration(P<0.05, P<0.01). The expression levels of key proteins PI3K, phosphorylation(p)-PI3K, Akt1, p-Akt1, mTOR, p-mTOR, and HIF-1α in lung tissue were analyzed by immunohistochemistry and Western blot. Compared with the blank group, the model group showed increased expression of key proteins(P<0.05, P<0.01). Compared with the model group, the XQL administration group exhibited decreased expression of key proteins(P<0.05, P<0.01). ConclusionXQL can reduce lung inflammation and improve HAPE. The mechanism may be related to the regulation of PI3K/Akt/mTOR and HIF-1α pathways. This study provides a new idea and a theoretical basis for the treatment of HAPE with XQL.

Objective:To investigate the efficacy and safety of the combination therapy of venetoclax (VEN) and azacitidine (AZA) in treatment of newly diagnosed elderly patients with acute myeloid leukemia (AML).Methods:A retrospective cohort study was conducted. The clinical data of 17 newly diagnosed elderly AML patients who received VEN+AZA regimen at the First Hospital of Putian City from April 2021 to June 2023 were collected. Treatment outcomes and adverse events were analyzed. Survival curves were plotted by using the Kaplan-Meier method, and intergroup comparisons were performed by using the log-rank test.Results:Among the 17 patients, the median age [ M ( Q1, Q3)] was 70 (68, 74) years, with 11 males (64.7%) and 6 females (35.3%). The median number of treatment courses was 4.0 (2.5, 8.5). After the first course, the composite complete remission (cCR) rate was 41.2% (7/17), minimal residual disease (MRD) negativity rate was 5.9% (1/17), and overall response rate (ORR) was 82.4% (14/17). By the end of follow-up in September 2023, the cCR rate reached 64.7% (11/17), MRD negativity rate was 52.9% (9/17), and ORR was 88.2% (15/17). The median number of courses to achieve cCR was 1.0 (1.0, 2.0), and to achieve MRD negativity was 3.0 (2.0, 3.5). The follow-up rate was 88.2% (15/17), and the median follow-up time was 17.3 months (95% CI: 7.0-27.6 months). The median progression-free survival (PFS) time was 6.5 months (95% CI: 1.7-11.3 months), and median overall survival (OS) time was 12.0 months (95% CI: 0.3-23.7 months). The median OS time after progression was 1.5 months (95% CI: 1.0-2.0 months). All patients experienced hematological adverse events, with 94.1% (16/17) experiencing grade ≥ 3 hematological adverse events. The most common non-hematological adverse event was infection (88.2%, 15/17), with the lung being the most frequent site of infection (82.4%, 14/17), while 41.2% (7/17) of patients had pre-existing infections before treatment. Conclusions:The VEN+AZA regimen demonstrates high remission rates and significant efficacies in treating newly diagnosed elderly AML patients. Although adverse events occur in nearly all patients, most are able to tolerate the treatment.

Objective:Diabetic retinopathy (DR) is the most common cause of adult blindness in China. Screening of DR is important for early detection, prevention, and treatment. However, there is still controversy in the research on the prevalence and risk factors of DR in China. This study was designed to evaluate the prevalence of DR and related risk factors in patients with type 2 diabetes mellitus in Beijing City.Methods:A cross-sectional survey was conducted in in Dongcheng District and Tongzhou District, Beijing City. Patients with type 2 diabetes aged 18-80 years were selected from four communities, and all subjects underwent questionnaires, physical examinations, laboratory examinations and fundus photography. The logistic regression model was used to analyze the associated factors of DR.Results:A total of 1 531 subjects were included, with the median age of 66 years old and the average age of (65.6±7.4) years old, and the glycosylated hemoglobin level in the subjects was 7.2%±1.3%, and the glycosylated hemoglobin compliance rate was 56.0%(857/1 531). A total of 254 patients with diabetic retinopathy were detected, and the prevalence of DR was 16.6%(254/1 531). Among them, there were 218 cases of non-proliferative diabetic retinopathy and 36 cases of proliferative diabetic retinopathy. Compared with the non-DR group, there were statistically significant differences in fasting blood glucose ( Z=-3.74, P<0.001), glycosylated hemoglobin( Z=-10.664, P<0.001), urinary microalbumin excretion rate( Z=-7.767, P<0.001), low-density lipoprotein cholesterol( Z=-2.589, P=0.01), and duration of diabetes( Z=-10.189, P<0.001) between the DR group and the non-DR group. Multivariate regression analysis showed that the duration of diabetes ( OR=1.08, 95% CI: 1.06-1.10, P<0.001), glycosylated hemoglobin ( OR=1.38, 95% CI: 1.23-1.55, P<0.001), and FPG ( OR=1.11, 95% CI: 1.03-1.19, P=0.008) were associated factors for DR. Conclusion:In this study, the prevalence of DR in 4 communities of type 2 diabetes in Beijing City was 16.6%. Besides, this study further confirmed that the duration of diabetes, fasting blood glucose levels, and glycosylated hemoglobin are associated factors for DR in patients with type 2 diabetes.

Follicular lymphoma (FL) is highly heterogeneous with different histopathologic grades. Its biological characteristics and clinical management are different. This study retrospectively analyzed 18F-FDG PET-CT metabolic parameters, clinical features, and their relationship with prognosis in 161 FL patients with different histopathological grades (grade 1-2, grade 3A, grade 3B) at the Shanxi Cancer Hospital. There were 93 cases in the grade 1-2 group, 40 cases in the grade 3A group, and 28 cases in the grade 3B group. The expression of LDH, CD10, EZH2, c-Myc, and CD37 proteins was correlated with histological grade (grade 1-2, grade 3A, and grade 3B) (all P values<0.05) . The SUVmax, TLG, TBR, and TLR for the three groups were different (all P values<0.05) . The optimal thresholds of SUVmax, MTV, TLG, TBR, and TLR for predicting FL disease progression were 8.32, 201.31, 2 342.55, 6.56, and 3.52, respectively, and the rate of disease progression increased in patients with higher thresholds (all P value<0.05) . β 2-MG (>2.3 μg/L) , Follicular lymphoma international prognostic index-1 (FLIPI-1) score (3-5 points) , negative CD37 expression, positive c-Myc expression, and TLG (>2 342.55 g) were all independent risk factors for PFS in the FL patients ( HR=3.609, 2.509, 0.255, 3.506, 13.531, all P value<0.05) . 18F-FDG PET-CT is a powerful complement to FL histopathological grading and the combination of the two may better predict the prognosis of FL patients.
