Asthma is a chronic inflammatory respiratory disease involving multiple cells and cellular components， characterized by recurrent episodes of wheezing， shortness of breath， chest tightness， and coughing， significantly impacting patients' quality of life. The phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway， as a crucial hub in intracellular signaling， is widely involved in the regulation of cell growth， proliferation， survival， metabolism， and a series of pathophysiological processes. Its regulatory role in the pathological progression of asthma is particularly significant， specifically in promoting airway inflammation， mediating epithelial mesenchymal transition， accelerating airway remodeling， regulating cell autophagy， inducing mucus hypersecretion， and influencing immune response balance. This study analyzed potential molecular targets of the PI3K/Akt pathway， including activators such as cysteine proteinase inhibitor 1（CST1）， found in inflammatory zone 1（FIZZ1） and free fatty acid receptor 1（FFAR1）， and inhibitors such as human β-defensin-3（hBD-3）， disintegrins， metalloproteinase 33（ADAM33） and interleukin-27（IL-27）， and initially revealed the potential molecular mechanisms of traditional Chinese medicine（TCM） in asthma intervention. Based on this， the authors systematically summarized the efficacy and specific mechanisms of TCM monomers， compounds， and external treatments for asthma by regulating the PI3K/Akt signaling pathway through literature review and analysis， aiming at establishing a robust foundation for the wide application and advanced development of TCM in asthma treatment， offering innovative insights for clinical research and drug development of asthma.

Objective To evaluate the feasibility of establishing canine rectovaginal fistula ani-mal model using magnetic surgery techniques.Methods Ten female Beagle dogs were randomly di-vided into study group(n=5)and control group(n=5).The study group underwent rectovaginal fistula modeling using magnetic surgery technology,while the control group was subjected to sharp puncture of the rectovaginal septum followed by indwelling rubber tube placement to establish the model.Surgical procedure duration and postoperative adverse events were recorded in both groups.Two weeks later,the magnets and rubber tubes were removed.The formation of rectovaginal fistulas in the animals of two groups was observed,and the success rates of model construction of two groups were statistically analyzed.Results Both groups successfully completed the preparation of the recto-vaginal fistula models.The operative time in both groups was less than 2 minutes.No adverse events such as magnet detachment were observed in the study group during the postoperative period.In the control group,the rubber tube dislodged on day 6 post-surgery in one dog,leading to spontaneous healing of the fistula.Two weeks after surgery,the magnets and rubber tubes were removed.Naked-eye observation showed that the rectovaginal fistula formed well in the experimental dogs of the study group,while the rectovaginal fistula formed well in 4 experimental dogs in the control group.The success rate of model construction in the study group was 100％,and was 80％in the control group.Conclusion The construction of a canine rectovaginal fistula model by magnetosurgical techniques has the advantages of simple operation and high success rate.Magnetosurgical techniques may serve as an ideal animal model for constructing and studying the histopathological changes and treatment methods of rectovaginal fistulas.

Objective:To investigate the predictive value of mucosal vascular pattern (MVP) under narrow-band imaging (NBI) enteroscopy in patients with ulcerative colitis (UC) in clinical remission for histological healing and clinical recurrence.Methods:A total of 142 patients with UC in clinical remission who visited the First Affiliated Hospital of Weifang Medical University from January 2018 to January 2021 were included in the study and underwent colonoscopy. The white light and NBI endoscopic images were collected and biopsies were obtained. The Mayo endoscopic score (MES) was calculated based on white light images, and MVP staging was evaluated based on mucosal vascular patterns under NBI. Nancy index (NI) was used to evaluate histological healing and patients were followed up for 1 year. The Spearman correlation coefficients of MES and MVP with histological healing and recurrence were calculated. The receiver operator characteristic (ROC) curve was plotted and the area under curve (AUC) was applied to evaluate the accuracy of white light and NBI endoscopy for predicting histological healing of UC in clinical remission.Results:According to the MVP criteria, 47 were defined as clear, 63 blurred, and 32 invisible. Spearman correlation analysis showed a significant correlation between MVP under NBI and histological healing ( r=0.549, P<0.001) and a moderate correlation between MES under white light and histological healing ( r=0.462, P<0.001). Spearman correlation analysis showed a moderate correlation between MVP under NBI and clinical recurrence ( r=0.451, P<0.001) and a moderate correlation between MES under white light and clinical recurrence ( r=0.352, P<0.001). AUC of NBI for diagnosing histological healing of UC in clinical remission was 0.809 (95% CI: 0.738-0.879), with a sensitivity of 84.6% (77/91) and specificity of 64.7% (33/51), superior to the white light endoscopy, of which AUC, sensitivity and specificity were 0.763 (95% CI: 0.678-0.848), 81.3% (74/91) and 66.7% (34/51). Conclusion:MVP staging under NBI could predict histological healing of UC patients in clinical remission and is superior to white light endoscopy.

Objective:To explore the TCM syndromes and risk factors of patients with anxiety and/or depression after coronary revascularization through real-world data mining based on the national pilot project of Chinese and Western medicine clinical collaboration for major difficult diseases; To provide clinical evidence and guide practice for the diagnosis and treatment of bicardiac diseases after coronary revascularization.Methods:A retrospective multi-center clinical study was conducted. From September 2018 to December 2019, 577 patients who underwent successful percutaneous coronary intervention in the Department of Cardiovascular Medicine of Affiliated Hospital of Liaoning University of Traditional Chinese Medicine, Department of Cardiovascular Medicine of the People's Hospital of Liaoning Province were enrolled using the collaborative platform system of TCM and Western Medicine Diagnosis and follow-up for coronary disease. Clinical data database was established. Baseline data, TCM syndrome types and elements, coronary angiography and stent implantation status, relevant disease history, Hamilton Anxiety and Depression Scale, etc. were collected. A combination of postoperative phone calls and outpatient visits was performed, with follow-up every 3 months for a total of 1 year. The TCM treatment patterns and risk factors of patients with anxiety and depression after coronary artery revascularization surgery were analyzed and explored.Results:A total of 577 patients were enrolled and 561 patients were followed up. Age distribution: The age of males and females undergoing coronary revascularization due to ACS was (61.80±11.00) years and (68.37±10.13) years, with no statistical significance between groups ( P>0.05), but the age of onset in males tended to be earlier than in females. The distribution pattern of TCM syndrome elements showed that the most deficiency syndrome elements were qi deficiency (61.75%, 176/285), followed by yin deficiency (28.77%, 82/285). The most common excessive symptom was blood stasis (39.13%, 108/276), and the other syndromes were phlegm turbidity (36.23%, 100/276) and qi depression (20.29%, 56/276), etc. The distribution of TCM syndrome types was as follows: in the population with anxiety and depression state of coronary revascularization, the TCM syndrome types with frequency higher than 10% were successively phlegm and blood stasis with depression syndrome, qi deficiency and blood stasis syndrome, heart, gallbladder and qi deficiency and qi-yin deficiency with blood stasis syndrome. Among the people without anxiety and depression, the TCM syndromes with a frequency higher than 10% were heart blood stasis syndrome and qi deficiency and blood stasis syndrome, with statistical significance ( χ2=12.07, P<0.01). Correlation analysis showed that the number of stents, and LDL-C were positive correlated with anxiety and depression( r values were 0.107, 0.118,respectively, P<0.05), and the uric acid was negative correlation ( r=-0.127, P=0.011). Multivariate Cox proportional hazards regression showed the age [ RR (95% CI)=1.052 (1.012-1.094), P=0.010] and diabetes mellitus [ RR (95% CI)=4.561 (1.028-20.238), P=0.046] at the sixth month of treatment. Conclusions:The age of acute coronary syndrome and coronary revascularization is mainly concentrated in patients aged 60-70 years, and male patients tend to have earlier onset than female patients, and the risk of coronary heart disease is relatively high. Qi-deficiency syndrome accounts for the highest proportion, and the most excessive syndrome is blood stasis syndrome. The TCM syndromes with high frequency of anxiety and depression are phlegm and blood stasis with depression syndrome and qi-yin deficiency with blood stasis syndrome. The number of stents implanted and low density lipoprotein cholesterol are positively correlated with postoperative anxiety and depression. Age and diabetes history are independent risk factors for end-point events at about 6 months after treatment.

Background Magnesium is an important nutrient, and participates in most metabolic processes. Many studies show an association between dietary magnesium intakes and nutrition-related diseases such as diabetes. However, the data of dietary magnesium intakes and secular trends among the whole life cycle of Chinese residents are not available. Objective To investigate the dietary magnesium intakes and associated secular trends over the past three decades in residents of all ages and China, to identify the high-risk residents of magnesium deficiency and plan nutritional interventions, and provide basic data support for the revision of dietary magnesium reference intake. Method The data came from the 10 rounds of the "China Health and Nutrition Survey" from 1991 to 2018, and the participants with complete sociodemographic and dietary data wereselected. The median intakes, insufficient rates, and secular trends of dietary magnesium intakes were analyzed in different survey years. Analysis of multiple linear regression was used to analyze the annual change characteristics of dietary magnesium intakes controlling gender, age, education, urban-rural stratum, and north-south region. Wilcoxon trend test was used to analyze the secular trends of dietary magnesium intakes in different characteristic groups. The trends of insufficient rate were analyzed by Cochran-Armitage trend test among different characteristic groups. Results A total of 127169 residents were included in the present study. The medians of dietary magnesium intakes in 1991, 1993, 1997, 2000, 2004, 2006, 2009, 2011, 2015, and 2018 were 283.70, 283.38, 304.26, 285.50, 283.64, 275.49, 267.92, 242.93, 240.51, and 238.89 mg·d⁻¹, respectively, showing a significant downward trend (F=2931.81, P<0.001). Dietary magnesium intakes showed significant differences in gender, age, education level, income level, urban-rural stratum, and north-south region in almost all survey years, except that there was no significant difference among different income groups in 1991. Insufficient rate of dietary magnesium intake showed a significant upward trend (Z=62.62, P<0.001), approximate 60% of Chinese residents consumed insufficient magnesium. The insufficient rate was 53.94% for male and 65.35% for female, and the insufficient rate in the 14-17 age group was as high as 71.29%. Conclusion The dietary magnesium intake shows a significant downward trend and insufficient intake of dietary magnesium is prevalent among Chinese population. It is necessary to observe the high-risk population and conduct relevant nutritional interventions, as well as to further assess the recommended intake of magnesium.
