As an exclusive Miao medicine of Honwing Pharma （Guizhou） Co. Ltd.， Yifei Zhike capsules are both a prescription drug and an over-the-counter （OTC） drug. Its main ingredients include Ranunculus ternatus and Panax notoginseng. With the effects of nourishing Yin and moistening the lungs， as well as relieving cough and reducing phlegm， Yifei Zhike capsules are often used in the treatment of acute and chronic bronchitis， pulmonary tuberculosis， and other diseases. However， there is insufficient understanding of their efficacy， suitable syndromes， and safety in clinical practice， with a lack of relevant expert consensus on clinical application. To standardize their clinical application， 30 experts from the fields of respiratory medicine， pharmacy， and evidence-based medicine were invited to develop an Expert Consensus on the Clinical Application of Yifei Zhike Capsules （Consensus for short） through evidence-based medicine methods. The Consensus clarified the syndrome characteristics， disease stages， dosages， treatment courses， combined medication， and other norms in the treatment of acute/chronic bronchitis and pulmonary tuberculosis and could be applicable to clinical physicians and pharmacists in medical and health institutions at all levels. In disease diagnosis， it provided diagnostic criteria for traditional Chinese medicine and Western medicine and clarified that the suitable traditional Chinese medicine syndrome was the syndrome of Qi-Yin deficiency with intermingled phlegm-blood stasis. Clinical studies have confirmed that Yifei Zhike capsules combined with standard anti-tuberculosis therapy can effectively improve the symptoms of pulmonary tuberculosis patients， increase the sputum smear conversion rate， and promote the absorption of lesions. When treating acute cough caused by respiratory tract infections， Yifei Zhike capsules can increase the markedly effective rate and the seven-day disappearance rate of cough symptoms. Meanwhile， recommendations for specific usage， dosages， and treatment courses were given for different diseases， and it was pointed out that long-term medication required key monitoring of adverse reactions. In safety， the adverse reactions of Yifei Zhike capsules involved multiple aspects such as the digestive system and allergic reactions， and pregnant women and women during menstruation were prohibited from using it. In addition， modern research has shown that Yifei Zhike capsules have an adjuvant therapeutic effect on tuberculous pleurisy and may be effective for inflammatory and benign pulmonary nodules. However， further research should be conducted on the toxicological safety of long-term medication. The formulation of the Consensus provides a scientific basis for the rational clinical application of Yifei Zhike capsules， which helps to improve clinical efficacy and reduce medication risks.

In addition， through policy alignment， academic promotion， and a dynamic revision mechanism， the standardization of clinical application was promoted， providing a demonstration for the evidence-based transformation of characteristic therapies of Miao medicine.

Objective To explore the efficiency improvement in segmenting neural network with the application of Transformer + U-Net artificial intelligence (AI) and modeling with the application of Python scripts in three-dimensional (3D) printing brachytherapy. Methods A Transformer + U-Net AI neural network model was constructed, and Adam optimizer was used to ensure rapid gradient descent. Computed tomography or magnetic resonance imaging data of patients were standardized and processed as self-made data sets. The training set was used to train AI and the optimal result weight parameters were saved. The test set was used to evaluate the AI ability. Python programming language was used to write an automated script to obtain the output segmentation image and convert it to the STL file for import. The source applicator and needle could be automatically modeled. The time of automatic segmentation and modeling and the time of manual segmentation and modeling were entered by two people, and the difference was verified by paired t-test. Results Dice similarity coefficient (DSC), mean intersection over union (MIOU), and Hausdorff distance (HD95) were used for evaluation. DSC was 0.9341, MIOU was 0.8762, and mean HD95 was 2.516. The mean time of manual segmentation was 1187 s, and the mean time of AI segmentation was 145 s (P < 0.01). The mean time of manual modeling was 321 s, and the mean time of modeling with Python automated scripts was 18 s (P < 0.01). Conclusion The application of Transformer + U-Net automatic segmentation and Python automated scripts can effectively improve work efficiency in the 3D printing brachytherapy for cervical cancer.

Ovarian cancer is the most lethal malignancy affecting the female reproductive system. Pharmacological inhibitors targeting CDK4/6 have demonstrated promising efficacy across various cancer types. However, their clinical benefits in ovarian cancer patients fall short of expectations, with only a subset of patients experiencing these advantageous effects. This study aims to provide further clinical and biological evidence for antineoplastic effects of a CDK4/6 inhibitor (TQB4616) in ovarian cancer and explore underlying mechanisms involved. Patient-derived ovarian cancer organoid models were established to evaluate the effectiveness of TQB3616. Potential key genes related to TQB3616 sensitivity were identified through RNA-seq analysis, and TRIM4 was selected as a candidate gene for further investigation. Subsequently, co-immunoprecipitation and GST pull-down assays confirmed that TRIM4 binds to hnRNPDL and promotes its ubiquitination through RING and B-box domains. RIP assay demonstrated that hnRNPDL binded to CDKN2C isoform 2 and suppressed its expression by alternative splicing. Finally, in vivo studies confirmed that the addition of siTRIM4 significantly improved the effectiveness of TQB3616. Overall, our findings suggest that TRIM4 modulates ubiquitin-mediated degradation of hnRNPDL and weakens sensitivity to CDK4/6 inhibitors in ovarian cancer treatment. TRIM4 may serve as a valuable biomarker for predicting sensitivity to CDK4/6 inhibitors in ovarian cancer.

Objective: To understand the association between beverage and snack intake and insufficient serum 25 hydroxyvitamin D [25(OH)D] among primary and secondary school students, so as to provide a scientific basis for targeted intervention measures. Methods: From October to December 2021, a stratified random sampling method was used to select 2 477 primary and secondary school students aged 8 to 15 years old from 9 counties in Yunnan Province implemented the Nutrition Improvement Plan for Rural Compulsory Education Students. The intake of beverages and snacks was investigated using the Rural Student Nutrition Monitoring Questionnaire from Chinese Center for Disease Control and Prevention. The snack intake intensity was calculated and classified into no intake, extremely low, low, medium, and high intensity. Serum 25(OH)D levels were measured in the laboratory, and levels <20 ng/mL were defined as insufficient. Chi square tests, LASSO regression, random forest and binary Logistic regression were used to analyze the association between 20 types of beverages and snacks and serum 25(OH)D insufficiency. Results: Insufficient serum 25(OH)D was detected in 564 boys (45.9%) and 855 girls (68.5%), with a total of 1 419 cases (57.3%). Binary Logistic regression results showed that extremely low intake intensity of carbonated beverages ( OR =1.51), plant protein beverages ( OR =1.61), and milk tea beverages ( OR =1.39) increased the risk of insufficient serum 25(OH)D, while protective factors were fruits and vegetables ( OR =0.77) and pure milk and yogurt ( OR =0.74) (all P <0.05). Subgroup analysis showed that extremely low intake intensity of carbonated beverages, milk containing beverages, tea beverages, fruit and vegetable juices, and plant protein beverages increased the risk of insufficient serum 25(OH)D in girls ( OR =2.22, 1.72, 1.67, 1.74, 1.92), and high intake intensity increased the risk of insufficient serum 25(OH)D in boys ( OR =1.73, 1.48, 1.52, 1.49, 1.97) (all P <0.05). Extremely low intake intensity of carbonated beverages, plant protein beverages, and milk tea beverages in junior high school students ( OR =1.92, 2.54, 1.68) and low intake intensity in primary school students ( OR =1.40, 1.33, 1.45) increased the risk of insufficient serum 25(OH)D (all P <0.05). Conclusions Frequent intake of beverages and highly processed snacks increases the risk of insufficient serum 25(OH)D in primary and secondary school students, while natural foods such as fruits, vegetables, pure milk and yogurt can reduce the risk. Girls and junior high school students are more susceptible to these effects.

AIM:This study aimed to explore the induction of ferroptosis in non-small-cell lung cancer(NSCLC)cells by tubeimoside II(TBMS II)and to elucidate the underlying molecular mechanisms.METHODS:H460 NSCLC cells were cultured in vitro.Cell survival rates were assessed by using MTT assays,and doses of TBMS II resulting in below 50%survival were selected for further experimentation.Cell migration was evaluated using Transwell assays and the effects of TBMS II on H460 cell proliferation were assessed by colony formation assays.Flow cytometry and fluores-cence microscopy were used to assess changes in lipid peroxidation(lipid ROS),and the levels of GSH,T-AOC,MDA,and Fe2+were measured using commercial kits.Protein levels of GPX4,SLC7A11,FTH1,NCOA4,P62,and LC3 were examined using Western blot.Changes in mitochondrial structure were detected by transmission electron microscopy,and immunofluorescence was used to assess LC3 co-localization of FTH1 and NCOA4,as well as co-localization of LC3 and NCOA4 with lysosomes.RESULTS:Compared with the control group,TBMS II dose-dependently reduced H460 cell via-bility,migration,and clone formation,accompanied by the appearance of vacuoles within the cells.TBMS II treatment al-so led to decreased GSH and T-AOC levels,while increasing the cellular contents of MDA,indicating oxidative stress.Ad-ditionally,there was a decrease in the expression of the antioxidant proteins SLC7A11 and GPX4 in the cells,while lipid ROS and Fe2+levels were increased in proportion to the TBMS II concentration.The ferroptosis inhibitor ferrostatin-1 re-versed cell death caused by TBMS II,suggesting ferroptosis induction.Furthermore,increasing the TBMS II concentra-tion resulted in an upregulation of the autophagy marker proteins LC3 II/LC3 I and P62,indicative of increased autopha-gy.TBMS II also affected mitochondrial morphology in the cells,as seen in reduced mitochondrial fluorescence intensity.Protein expression of NCOA4 increased with higher TBMS II concentrations,while that of FTH1 decreased.Co-localiza-tion of LC3 II with FTH1 and NCOA4,as well as the lysosomal association of LC3 II and FTH1,also increased in a dose-dependent manner.CONCLUSION:TBMS II induces ferritinophagy in H460 cells,leading to decreased cell viability and increased ferroptosis.

Cerebral hyperperfusion syndrome (CHS) is a rare but serious complication after cerebral revascularization, which may lead to catastrophic consequences. The mechanism of CHS is not fully understood, and it may be related to cerebral autoregulation dysfunction and the increase of blood pressure after operation. Timely detection and treatment of cerebral hyperperfusion can avoid CHS. This article reviews the pathogenesis, diagnosis, clinical manifestations, prevention and treatment of CHS.

Objective:To evaluate the effects of fine particle matter(PM2.5)and ozone(O3)com-bined exposure on adenosine triphosphate(ATP)amount and ATPase activities in nasal mucosa of Spra-gue Dawley(SD)rats.Methods:Twenty male SD rats were divided into control group(n=10)and exposure group(n=10)by random number table method.The rats were fed in the conventional clean environment and the air pollutant exposure system established by our team,respectively,and exposed for 208 d.During the exposure period,the concentrations of PM2 5 and O3 in the exposure system were moni-tored,and a comprehensive assessment of PM2 5 and O3 in the exposure system was conducted by combi-ning self-measurement and site data.On the 208 d of exposure,the core,liver,spleen,kidney,testis and other major organs and nasal mucosal tissues of the rats were harvested.Each organ was weighed and the organ coefficient calculated.The total amount of ATP was measured by bioluminescence,and the ac-tivities of Na+-K+-ATPase and Ca2+-ATPase were detected by spectrophotometry.The t test of two inde-pendent samples was used to compare the differences among the indicator groups.Results:From the 3rd week to the end of exposure duration,the body weight of the rats in the exposure group was higher than that in the control group(P＜0.05),and there was no significant difference in organ coefficients be-tween the two groups.The average daily PM2 5 concentration in the exposure group was(30.68±19.23)μg/m3,and the maximum 8 h ozone concentration(O3-8 h)was(82.45±35.81)μg/m3.The chemi-luminescence value(792.4±274.1)IU/L of ATP in nasal mucosa of the rats in the exposure group was lower than that in the control group(1 126.8±218.1)IU/L.The Na+-K+-ATPase activity(1.53±0.85)U/mg in nasal mucosa of the rats in the exposure group was lower than that in the control group(4.31±1.60)U/mg(P＜0.05).The protein content of nasal mucosa in the control group and the exposure group were(302.14±52.51)mg/L and(234.58±53.49)mg/L,respectively,and the ac-tivity of Ca2+-ATPase was(0.81±0.27)U/mg and(0.99±0.73)U/mg,respectively.There was no significant difference between the groups.Conclusion:The ability of power capacity decreased in the rat nasal mucossa under the sub-chronic low-concentration exposure of PM2 5 and O3.

Objective To quantitatively analyze the effects of population aging and other risk factors on the burden of colorectal cancer in China from 1990 to 2019. Methods The Global Burden of Disease Study 2019 was used to describe the temporal trend of the burden of colorectal cancer. A decomposition method established by Gupta was applied to quantify the burden related to population growth, aging, age-specific prevalence, and disease severity. Results The age-standardized disability adjusted life years (DALY) rates of colorectal cancer in China showed an overall upward trend from 1990 to 2019. The DALY in 2019 increased by 191.12% compared with that in 1990, with 34.54% of the increase attributed to population growth, 111.36% to population aging, and 77.56% to the rise of age-specific prevalence. Meanwhile, -32.54% benefited from the changes in disease severity. Diet low in milk was the primary risk factor for the disease burden of colorectal cancer in China in 2019, followed by diet low in whole grains and calcium. In the last 30 years, the corresponding risk factor of the most rapid increase in China was high BMI with an average annual percentage of change of 4.14%, and the corresponding risk factor of the most rapid decrease in China was diet low in fiber with an average annual percentage of change of -2.00%. Conclusion Aging population is mainly responsible for the considerable increase in the burden of colorectal cancer in China from 1990 to 2019. The health administrative authorities should take corresponding measures to address the adverse impacts associated with aging.
