This study investigates the material basis and mechanism of Arisaematis Rhizoma Preparatum in the treatment of chronic obstructive pulmonary disease(COPD) using animal experiments, component analysis, network pharmacology, and molecular docking. A mouse model of COPD was constructed by cigarette smoke and lipopolysaccharide(LPS). Blood gas analysis was performed to measure the pH and partial pressure of carbon dioxide(PCO_2) in the blood of the mice. Lung tissue sections were analyzed using HE staining, and the effects of Arisaematis Rhizoma Preparatum water extract on inflammatory factors(TNF-α, IL-6, and IL-1β) and the PI3K/AKT signaling pathway in the lung tissue of COPD model mice were studied by qPCR and Western blot. The composition of the Arisaematis Rhizoma Preparatum water extract was analyzed using UPLC Q-Exactive Orbitrap MS. The SwissTargetPrediction database was used to predict the targets of the chemical components in Arisaematis Rhizoma Preparatum. GeneCards, OMIM, TTD, PharmGKB and DrugBank disease databases were used to screen for COPD targets, and the potential targets of Arisaematis Rhizoma Preparatum in treating COPD were identified. A protein-protein interaction(PPI) network of intersection targets was constructed and analyzed using the STRING database and Cytoscape 3.9.0, and core genes were screened. GO functional analysis and KEGG pathway enrichment analysis were performed using R language, and molecular docking verification was conducted using AutoDock Vina software. The results of the animal experiments showed that Arisaematis Rhizoma Preparatum water extract improved pulmonary ventilation function in COPD model mice, reduced lung inflammatory cells, decreased alveolar cavities, and improved lung tissue condition. The levels of inflammatory factors TNF-α, IL-6 and IL-1β were decreased, and the phosphorylation levels of PI3K and AKT were inhibited. Fifty-two chemical components were identified from Arisaematis Rhizoma Preparatum, and 440 intersection targets related to COPD were found. Nine key components were screened, including hydroxyphenylethylamine, L-tyrosine, L-tyrosyl-L-alanine, 3,4,5-trihydroxy-1-cyclohexene-1-carboxylic acid, methyl azelate, zingerone, 6-gingerol, linoleamide, and linoleoyl ethanolamine. Five core targets were identified, including AKT1, TNF, STAT3, ESR1, and IL1B. The PI3K/AKT pathway was identified as the key pathway for the treatment of COPD with Arisaematis Rhizoma Preparatum. Molecular docking results showed that 75% of the binding energies of key components and core targets were less than-5 kcal·mol~(-1), indicating good binding affinity. In conclusion, Arisaematis Rhizoma Preparatum may improve pulmonary ventilation function, enhance lung pathological morphology, and reduce pulmonary inflammation in COPD model mice by inhibiting the PI3K/AKT signaling pathway and downregulating TNF-α, IL-6, and IL-1β inflammatory factors. The material basis may be associated with L-tyrosyl-L-alanine, 3,4,5-trihydroxy-1-cyclohexene-1-carboxylic acid, zingerone and 6-gingerol, and AKT1 and TNF may be the primary targets.

OBJECTIVE:
Asthma imposes a significant global health burden. This study examines changes in the asthma-related disease burden from 1990 to 2021 and projects future burdens for 2050 under different scenarios.
METHODS:
Using data from the Global Burden of Disease 2021 study, we analyzed asthma incidence, prevalence, mortality, and disability-adjusted life years (DALYs) from 1990 to 2021. We projected the disease burden for 2050 based on current trends and hypothetical scenarios in which all risk factors are controlled. Temporal trends in age-standardized incidence, prevalence, mortality, and DALY rates were explored using Annual Percent Change.
RESULTS:
In 2021, the age-standardized rates for asthma incidence, prevalence, mortality, and DALYs in China were 364.17 per 100,000 (95% uncertainty interval [ UI]: 283.22-494.10), 1,956.49 per 100,000 (95% UI: 1,566.68-2,491.87), 1.47 per 100,000 (95% UI: 1.15-1.79), and 103.76 per 100,000 (95% UI: 72.50-145.46), respectively. A higher disease burden was observed among Chinese men and individuals aged 70 years or older. Compared to the current trend, a combined scenario involving improvements in environmental factors, behavioral and metabolic health, child nutrition, and vaccination resulted in a greater reduction in the disease burden caused by asthma.
CONCLUSION
Addressing modifiable risk factors is essential for further reducing the asthma-related disease burden.

AIM: To assess the repeatability and agreement of higher-order aberration obtained by adaptive optics visual simulator(VAO)compared with OPD-Scan Ⅲ.METHODS: A cross-sectional study was conducted from August to September 2023, including a total of 204 patients(204 eyes)with myopia whose right eyes were measured. The examinations were performed by the same skilled examiner using both devices separately. The VAO device was used to measure higher order aberrations of orders 3 to 6 at a pupil diameter of 4.5 mm, while both the VAO and OPD-Scan Ⅲ devices were utilized to measure total higher-order aberration(tHOA), spherical aberration(SA), coma aberration(Coma), and trefoil aberration(Trefoil)of the entire eye at pupil diameters ranging from 3 to 6 mm. Furthermore, the repeatability of whole eye aberration measurements obtained with the VAO device was evaluated and the agreement of the two devices was assessed.RESULTS: The whole-eye higher-order aberrations measured by VAO demonstrated excellent repeatability(0.767≤ICC≤0.941, Sw<0.01 μm, TRT<0.1 μm). There was no statistically significant difference in Coma measured by VAO or OPD-Scan Ⅲ for pupil diameters ranging from 4 to 6 mm(P>0.05), while a statistically significant difference was observed in whole-eye tHOA of other pupil diameters(all P<0.05). The agreement of aberration measurements for each order between VAO and OPD-Scan Ⅲ for 3 mm pupil diameters, SA at 4 and 5 mm pupil diameter and Coma at 4 mm pupil diameter showed a 95% limit of agreement(LoA)<0.1, indicating good agreement; however, poor agreement was found for the remaining aberration measurements at different pupil diameters, with a 95%LoA>0.1, and there were significant differences in higher-order aberrations measured by two devices under a pupil diameter of 3 mm(r=0.218-0.317, P<0.01), 4 mm(r=0.406-0.672, P<0.01), 5 mm(r=0.538-0.839, P<0.01 and r=0.030-0.109, P>0.01)and 6 mm(r=0.369-0.766, P<0.01).CONCLUSION: The VAO demonstrates favorable repeatability when assessing whole-eye higher order aberration under pupil diameters of 3-6 mm. However, there is inadequate agreement and interchangeability in whole-eye higher order aberration at 3-6 mm pupil diameter between VAO and OPD-Scan Ⅲ for clinical purposes.

ObjectiveTo investigate the possible mechanism of electroacupuncture at "Neiguan" (PC6) and "Zhongwan" (RN12) in the treatment of functional dyspepsia (FD). MethodsSPF male SD rats were randomly divided into model group, Neiguan (PC6) group, Zhongwan (RN12) group, and Neiguan-Zhongwan (PC6-RN12) group, with 8 rats in each group. Except for the normal group, the other groups of rats were cogavaged with 0.1% sucrose iodoacetamide solution combined with small platform standing training to establish FD rat models. After successful modeling, the rats in the normal group and model group were tied up for 30 min/d for 7 days; the Neiguan group, Zhongwan group, and Neiguan-Zhongwan group were treated with electroacupuncture intervention at "Neiguan" (PC6), "Zhongwan" (RN12), and "Neiguan" - "Zhongwan" (PC6-RN12) acupoints, respectively, using continuous wave, frequency of 2 Hz, current intensity of 1 mA, 30 min/d, and continuous intervention for 7 days. The general condition of rats in each group was observed. After treatment, the body weight and food intake of rats were measured, and the gastric emptying rate was calculated; HE staining was performed on the gastric antrum tissue of rats to observe the histopathologic changes; the expressions of calcitonin gene-related peptide (CGRP) and Ghrelin protein in gastric antrum were detected by Western Blot; the metabolites in gastric antrum tissues were detected by liquid chromatography-mass spectrometry (LC-MS), and differential metabolites were screened by correlation analysis, then Metabo Analyst 5.0 and KEGG databases were used for metabolic pathway analysis. ResultsUnder light microscope, the gastric antrum structure was complete and the glands were abundant. No obvious inflammation and edema were found in gastric mucosa. Compared with the normal group, the body weight, food intake, and gastric emptie rate of rats in model group decreased, the expression of Ghrelin protein decreased and the expression of CGRP protein increased in gastric antrum tissue (P<0.01). Compared with model group, the body weight, food intake, and gastric emptance rate of rats in Neiguan group, Zhongwan group and Neiguan-Zhongwan group all increased, CGRP protein expression decreased in Neiguan group, and Ghrelin protein expression increased and CGRP protein expression decreased in Zhongwan group and Neiguan-Zhongwan group (P<0.01 or P<0.05). Compared with Neiguan-Zhongwan group, Ghrelin protein expression decreased and CGRP protein expression increased in Neiguan group and Zhongwan group (P<0.05 or P<0.01). Metabolomics results showed that compared with normal group, the content of metabolites adenosine diphosphate ribose, adenosine monophosphate and adenosine diphosphate in gastric antrum tissue of model group decreased; compared with model group, the contents of adenosine diphosphate, adenosine diphosphate and citicoline in Neiguan group increased, the contents of nicotine adenine dinucleotide, cytidine diphosphate ethanolamine and citicoline in Zhongwan group increased, and the contents of adenosine diphosphate, cytidine diphosphate and citicoline in Neiguan-Zhongwan group increased (P<0.05 or P<0.01). Compared with model group, the main metabolic pathways of different metabolites in PC6-RN12 group were glycerophospholipid metabolism, taurine and hypotaurine metabolism, purine metabolism, starch and sucrose metabolism. ConclusionElectroacupuncture at “Neiguan” and “Zhongwan” acupoints can effectively regulate gastrointestinal motility and improve FD symptoms in FD rats, and the effect is better than that of "Neiguan" or "Zhongwan" acupoints alone. The mechanism may be related to the influence of related metabolites on energy metabolism, glucose metabolism and nucleotide metabolism, thereby regulating gastrointestinal motility hormones.

Objective:To investigate the therapeutic effect of high-flow nasal cannula oxygen therapy (HFNC) and non-invasive positive pressure ventilation (NPPV) on patients with pulmonary edema caused by seawater drowning.Methods:A retrospective analysis method was used. Based on the Utstein database of emergency drowning in the First Hospital of Qinhuangdao, the clinical data of patients with seawater drowning pulmonary edema admitted to the emergency medicine department of the First Hospital of Qinhuangdao from January 1, 2019 to December 31, 2022 were collected. The patients were divided into NPPV group and HFNC group according to different ventilation methods. The general data, endotracheal intubation rate in 7 days, arterial blood gas analysis indexes [arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2), arterial oxygen saturation (SaO 2)] and hemodynamic indexes (systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, blood lactic acid) before and after treatment, length of stay in intensive care unit (ICU), oxygen therapy comfort of the two groups were compared. Results:A total of 54 patients were enrolled, including 21 patients in the NPPV group and 33 patients in the HFNC group. There were no significant differences in gender, age, state of consciousness and other general information between the two groups. Compared with NPPV group, the rate of endotracheal intubation in HFNC group within 7 days was significantly lower [24.2% (8/33) vs. 33.3% (7/21), P < 0.05]. Before treatment, there were no significant differences in arterial blood gas analysis and hemodynamics between the two groups. After treatment, the above indexes in both groups were significantly improved compared with those before treatment, and PaO 2, SaO 2, systolic blood pressure, diastolic blood pressure and mean arterial pressure in HFNC group were significantly higher than those in NPPV group [PaO 2 (mmHg, 1 mmHg≈0.133kPa): 93.56±6.37 vs. 82.14±6.25, SaO 2: 1.02±0.09 vs. 0.95±0.11, systolic blood pressure (mmHg): 117.37±8.43 vs. 110.42±8.38, diastolic blood pressure (mmHg): 79.43±7.61 vs. 72.21±4.32, mean arterial pressure (mmHg): 92.34±6.32 vs. 85.12±5.38], PaCO 2, heart rate and blood lactic acid were significantly lower than those in NPPV group [PaCO 2 (mmHg) : 34.26±5.63 vs. 37.24±6.22, heart rate (times/min): 73.38±7.56 vs. 86.25±5.41, blood lactic acid (mmol/L): 1.38±0.36 vs. 2.25±1.14], and the differences were statistically significant (all P < 0.05). In addition, the length of ICU stay in HFNC group was significantly shorter than that in NPPV group (days: 13.30±2.38 vs. 16.27±4.26), and the comfort rate of oxygen therapy was significantly higher than that in NPPV group [66.7% (22/33) vs. 42.8% (9/21)], with statistical significance (all P < 0.05). Conclusion:HFNC can improve the oxygenation of patients with pulmonary edema caused by seawater drowning, improve hemodynamics, reduce the rate of tracheal intubation, shorten the length of ICU stay, and improve the comfort of oxygen therapy, which has certain clinical application value.

Subsequently, employing years of education as a covariate, an analysis of covariance was performed on the EBEDT behavioral results and the changes in prefrontal Oxy-Hb concentrations in the three groups.The statistical software was SPSS 25.0.Results:(1)The correct number of EBEDT in schizophrenia group (13.93±7.67) was significantly lower than that in major depressive disorder group (19.26±8.07) and normal control group (21.79±6.36)(both P<0.05), and the EBEDT reaction time in schizophrenia group ((3.97±1.77) s) was significantly longer than those in major depressive disorder group ((3.21±1.27) s) and normal control group ((2.63±0.62) s)(both P<0.05).(2)During the EBEDT task block, the normal control group showed increased activation levels in the frontal polar region, Broca's area, anterior motor cortex and supplementary motor area (SMA) compared with the control block( t=2.02-3.18, all P<0.05); and the schizophrenia group showed increased activation levels in the frontal eye field compared with the control block( t=2.26, P=0.03); while the major depressive disorder group exhibited decreased activation levels in the entire prefrontal lobe compared with the control block( t=-3.47--2.34, all P<0.05). (3)During the emotion recognition task of EBEDT, the activation levels of the frontal polar area (ch37), dorsolateral prefrontal cortex (ch31), Broca's area (ch49, ch51, ch53), and SMA (ch1, ch47, ch52) were significantly different among the major depressive disorder, schizophrenia and normal controls( F=3.23-5.53, all P<0.05). Further pairwise comparisons showed that the activation levels in all the above pathways were lower in the major depressive disorder group than those in the normal control group, and the activation levels in Broca's area (ch53) and SMA area (ch52) were lower in the schizophrenia group than those in the normal control group, while the activation levels in the frontal polar area (ch37) and Broca's area (ch49) were lower in the major depressive disorder group than those in the schizophrenia group(all P<0.05). Conclusions:In EBEDT, the activation patterns of the prefrontal cortex are different between patients with major depressive disorder and patients with schizophrenia. Patients with major depressive disorder have a decrease in prefrontal cortex activation, while patients with schizophrenia have an increase in the frontal eye field activation.The activation levels in prefrontal cortex of both patients group are lower than that of normal controls. Meanwhile, the prefrontal cortex activation level of patients with major depressive disorder is lower than that of patients with schizophrenia.

To explore the mechanism by which vinegar-processed Euphorbiae Pekinensis Radix regulates gut microbiota and reduces intestinal toxicity, this study aimed to identify key microbial communities related to vinegar-induced detoxification and verify their functions. Using a derivatization method, the study measured the content of short-chain fatty acids(SCFAs) in feces before and after vinegar-processing of Euphorbiae Pekinensis Radix. Combined with the results of previous gut microbiota sequencing, correlation analysis was used to identify key microbial communities related to SCFAs content. Through single-bacterium transplantation experiments, the role of key microbial communities in regulating SCFAs metabolism and alleviating the intestinal toxicity of Euphorbiae Pekinensis Radix was clarified. Fecal extracts were then added to a co-culture system of Caco-2 and RAW264.7 cells, and toxicity differences were evaluated using intestinal tight junction proteins and inflammatory factors as indicators. Additionally, the application of a SCFAs receptor blocker helped confirm the role of SCFAs in reducing intestinal toxicity during vinegar-processing of Euphorbiae Pekinensis Radix. The results of this study indicated that vinegar-processing of Euphorbiae Pekinensis Radix improved the decline in SCFAs content caused by the raw material. Correlation analysis revealed that Bifidobacterium was positively correlated with the levels of acetic acid, propionic acid, isobutyric acid, n-butyric acid, isovaleric acid, and n-valeric acid. RESULTS:: from single-bacterium transplantation experiments demonstrated that Bifidobacterium could mitigate the reduction in SCFAs content induced by raw Euphorbiae Pekinensis Radix, enhance the expression of tight junction proteins, and reduce intestinal inflammation. Similarly, cell experiment results confirmed that fecal extracts from Bifidobacterium-transplanted mice alleviated inflammation and increased the expression of tight junction proteins in intestinal epithelial cells. The use of the free fatty acid receptor-2 inhibitor GLPG0974 verified that this improvement effect was related to the SCFAs pathway. This study demonstrates that Bifidobacterium is the key microbial community responsible for reducing intestinal toxicity in vinegar-processed Euphorbiae Pekinensis Radix. Vinegar-processing increases the abundance of Bifidobacterium, elevates the intestinal SCFAs content, inhibits intestinal inflammation, and enhances the expression of tight junction proteins, thereby improving the intestinal toxicity of Euphorbiae Pekinensis Radix.
