Acute lung injury （ALI） is a common clinical inflammatory respiratory emergency with high morbidity and mortality， for which there is no effective and safe therapeutic drug. Nuclear factor-κB （NF-κB）， as a classic inflammatory signaling pathway， can interact with upstream and downstream regulatory factors such as Toll-like receptor 4 （TLR4）， mitogen- activated protein kinase （MAPK）， nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3）， high mobility group box-1 protein 1 （HMGB1）， to jointly affect ALI. This review summarizes the latest research findings in recent years regarding the treatment of ALI through traditional Chinese medicine （TCM） interventions targeting NF-κB signaling pathways. It has been found that a variety of TCM monomers （danshensu methyl ester， salidroside total glycosides， berberine， Codonopsis pilosula polysaccharides， ursolic acid， chrysophanol， and polyphenols from longan seed kernels， etc.） and compound formulas （Resolving-dampness and defeating-toxins formula， Jinyin qingre oral liquid， Xuebijing injection， Combined treatment of lung and intestine， Huangqi baihe decoction， etc.） can modulate NF-κB signaling pathway， and can prevent and control ALI by inhibiting inflammation， improving oxidative stress， reducing apoptosis and modulating the intestinal flora in a multi-pathway manner.

Conjunctival lymphangiectasia is a low-incidence ocular surface disease that is currently rarely reported in the relevant literature. It may be related to cosmetic eyelid surgery, tumor, radiation or chemotherapy and other factors and often causes a foreign body sensation, lacrimation, eye pain, visual fatigue and other discomfort. These symptoms of constant eye irritation affect the patient's quality of life. At present, anterior segment optical coherence tomography can be used for clinical diagnosis, and the novel monoclonal antibody D2-40, as a marker of lymphatic endothelial cell dilatation, has high specificity in pathological diagnosis. Previous studies have not fully defined the pathogenesis of the disease, and treatment methods vary. Conventional treatment has resulted in varying degrees of damage to the conjunctiva in patients. In recent years, anti-vascular endothelial growth factor drugs have been reported to be effective in treating the disease with few complications. This article reviews the pathogenesis, diagnosis and treatment of this rare disease in order to gain a better understanding of conjunctival lymphangiectasia and provide more support for clinical diagnosis and treatment.

ObjectiveTo develop a predictive model and application for spontaneous passage of common bile duct stones using automated machine learning algorithms given the complexity of treatment decision-making for patients with common bile duct stones， and to reduce unnecessary endoscopic retrograde cholangiopancreatography （ERCP） procedures. MethodsA retrospective analysis was performed for the data of 835 patients who were scheduled for ERCP after a confirmed diagnosis of common bile duct stones based on imaging techniques in Changshu First People’s Hospital （dataset 1） and Changshu Traditional Chinese Medicine Hospital （dataset 2）. The dataset 1 was used for the training and internal validation of the machine learning model and the development of an application， and the dataset 2 was used for external testing. A total of 22 potential predictive variables were included for the establishment and internal validation of the LASSO regression model and various automated machine learning models. The area under the receiver operating characteristic curve （AUC）， sensitivity， specificity， and accuracy were used to assess the performance of models and identify the best model. Feature importance plots， force plots， and SHAP plots were used to interpret the model. The Python Dash library and the best model were used to develop a web application， and external testing was conducted using the dataset 2. The Kolmogorov-Smirnov test was used to examine whether the data were normally distributed， and the Mann-Whitney U test was used for comparison between two groups， while the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. ResultsAmong the 835 patients included in the study， 152 （18.20%） experienced spontaneous stone passage. The LASSO model achieved an AUC of 0.875 in the training set （n=588） and 0.864 in the validation set （n=171）， and the top five predictive factors in terms of importance were solitary common bile duct stones， non-dilated common bile duct， diameter of common bile duct stones， a reduction in serum alkaline phosphatase （ALP）， and a reduction in gamma-glutamyl transpeptidase （GGT）. A total of 55 models were established using automated machine learning， among which the gradient boosting machine （GBM） model had the best performance， with an AUC of 0.891 （95% confidence interval： 0.859‍ ‍—‍ ‍0.927）， outperforming the extreme randomized tree mode， the deep learning model， the generalized linear model， and the distributed random forest model. The GBM model had an accuracy of 0.855， a sensitivity of 0.846， and a specificity of 0.857 in the test set （n=76）. The variable importance analysis showed that five factors had important influence on the prediction of spontaneous stone passage， i.e.， were solitary common bile duct stones， non-dilated common bile duct， a stone diameter of <8 mm， a reduction in serum ALP， and a reduction in GGT. The SHAP analysis of the GBM model showed a significant increase in the probability of spontaneous stone passage in patients with solitary common bile duct stones， non-dilated common bile duct， a stone diameter of <8 mm， and a reduction in serum ALP or GGT. ConclusionThe GBM model and application developed using automated machine learning algorithms exhibit excellent predictive performance and user-friendliness in predicting spontaneous stone passage in patients with common bile duct stones. This application can help avoid unnecessary ERCP procedures， thereby reducing surgical risks and healthcare costs.

It is believed that dampness is a key pathological factor contributing to digestive dysfunction in chronic renal failure. Damp pathogens tend to be entangled with or transformed into other pathogenic factors， obstructing the flow of qi， disturbing the functions of the zang-fu organs， and impairing the spleen and stomach's transportation and transformation functions， ultimately leading to disease onset. Based on this understanding， the treatment principle emphasizes dispelling dampness， regulating qi， and harmonizing the five zang organs. For the syndrome of spleen and kidney qi deficiency with dampness， the self-formulated Buyuan Fengzang Decoction （补元封藏煎） is used to tonify the kidney， secure essence， strengthen the spleen， and eliminate dampness. For the syndrome of turbid dampness obstructing the lung and stomach， the self-formulated Sulian Xiexin Decoction （苏连泻心汤） is applied to open with acrid， descend with bitter， dry dampness， and discharge turbidity. For the syndrome of dampness stagnating and transforming into heat， with concurrent spleen deficiency and liver qi stagnation， the self-formulated Chailian Wendan Decoction （柴连温胆汤） is employed to soothe the liver， strengthen the spleen， and disperse the accumulation. For the syndrome of damp obstruction with qi stagnation and constrained yang， the self-formulated Caozhi Erchen Decoction （草知二陈汤） is used to resolve dampness， relieve constraint， raise yang， and promote the defensive qi.

Objective:To systematically integrate domestic and international qualitative studies on the experiences of cardiac rehabilitation in patients with coronary heart disease (CHD), providing a reference for the development of cardiac rehabilitation in China.Methods:A systematic search was conducted for qualitative studies focusing on the theme or the sub-theme of cardiac rehabilitation experiences in CHD patients. The databases searched included China Biology Medicine disc, China National Knowledge Infrastructure, VIP, Wanfang Data, PubMed, Scopus, Embase, Web of Science, CINAHL, and the Cochrane Library, covering the period from their inception to November 1, 2022. The included literature underwent quality assessment and was subjected to Meta-synthesis using an aggregative integration approach.Results:Seventeen articles were ultimately included, yielding 71 distinct and clear research findings. These were categorized into 11 new categories, forming three integrated results: diverse attitudes, facilitating factors, and hindering factors.Conclusions:Currently, there is insufficient health education on cardiac rehabilitation by medical personnel, affecting patients' participation in cardiac rehabilitation programs. Medical staff should expedite the construction of cardiac rehabilitation centers to meet the rehabilitation needs of patients.

Objective To understand the composition of death causes of residents in Tianzhu Tibetan Autonomous County,Wuwei City,and to analyze the current situation of life expectancy and life loss of residents,so as to provide evidence for disease control and health promotion.Methods According to the international classification of diseases(ICD-10),the population data and death cause monitoring data of Tianzhu Tibetan Autonomous County in 2021 were analyzed,standardized with the data of the seventh national census,and analyzed with SPSS 21.0 software and life expectancy statistics.Results The crude mortality rate of residents in Tianzhu Tibetan Autonomous County was 642.25/100 000,The male crude mortality(727.12/100 000)rate was higher than the female(553.29/100 000).The overall life expectancy was 79.07 years.The life expectancy in males was 76.77 years and the life expectancy in females was 81.47 years.The first five causes of death were circulatory system(mortality 270.14 per 100,000),nervous system(mortality 159.57 per 100,000),malignant tumor(mortality 101.97 per 100,000),respiratory system(mortality 27.81 per 100,000)and gastrointestinal disease disease(mortality 26.48 per 100,000).The first five places of AYLL were injury and poisoning(24.81 years/person),spirit and blood(15.42 Years/person),infectious diseases(13.06 years/person),malignant tumor(11.78 Years/person)and urogenital diseases(9.94 years/person).Conclusion The highest mortality rate in the 2021 Bairi Tibetan Autonomous County was circulatory system disease,and the major causes of premature death were injury and poisoning.

Objective To investigate the protective effects of Sulforaphane(SFN)against high glucose(HG)-induced human platelet apoptosis and elucidate the underlying mechanisms in vitro.Methods Purified platelets obtained from healthy individuals were pre-incubated with various concentrations of SFN(5,10,or 20 μmol/L)or a vehicle control(0.05%DMSO)for 40 minutes at 37℃.Subsequently,the platelets were stimulated with normal glucose(NG,5 mmol/L)or high glucose(HG,25 mmol/L)for an additional duration of 90 minutes.Flow cytometry was employed to assess platelet mitochondrial membrane potential depolarization(Δψm),exposure of phosphatidylserine(PS),and generation of total intraplatelet reactive oxygen species(ROS).Phosphorylation levels of PI3K and Akt were determined using Western blot.Results Compared to NG-treated human platelets,HG significantly induced depolarization of platelet Δψm and exposure of PS(P＜0.001).These effects of HG were markedly attenuated by various concentrations of SFN(P＜0.001).Mechanistically,SFN down-regulated the phosphorylation levels of PI3K(P＜0.01)and Akt(P＜0.05),which were increased by HG when compared to the vehicle control,and substantially reduced total intracellular ROS levels(P＜0.001).The inhibitory effects of SFN on HG-induced phosphorylation of PI3K and Akt,as well as its efficacy on total intracellular ROS generation,Δψm depolarization,and PS exposure in HG-stimulated human platelets were completely reversed by a specific agonist for PI3K,740 Y-P.Conclusions The current study demonstrates that SFN exerts a protective effect on platelet apoptosis induced by HG,potentially through the down-regulation of the PI3K/Akt-mediated pathway in human platelets in vitro.These findings suggest that SFN may hold promise for improving thrombosis in diabetes mellitus and related chronic metabolic diseases.

Objective To propose a deep learning neural network approach for transforming megavoltage computed tomography(MVCT)images of cervical cancer into pseudo kilovoltage computed tomography(kVCT)images with high signal-to-noise ratio and contrast-to-noise ratio,thus providing three-dimensional anatomical images and localization information required for adaptive radiotherapy of cervical cancer,and guiding the accelerator to achieve precise treatment.Methods The MVCT and kVCT images of 54 patients treated with cervical cancer radiotherapy were collected,with 44 cases randomly selected as the training set,and the remaining 10 cases as the test set.A cyclic generative adversarial network with gating mechanism and multi-channel data input was used to synthesize pseudo-kVCT images from MVCT images.The network training results were evaluated with imaging quality evaluation parameters,such as mean absolute error(MAE),peak signal-to-noise ratio(PSNR),and structural similarity index(SSIM).Results The MAE,PSNR,and SSIM of MVCT imagesvspseudo-kVCT(5:5)images were(24.9±0.7)HUvs(17.8±0.3)HU,(29.8±0.2)dBvs(30.7±0.2)dB,and 0.841±0.007 vs 0.898±0.003,respectively.Conclusion The generated pseudo-kVCT images have advantages in noise reduction and contrast enhancement,and can reduce the need for additional MV-kVCT electron density calibration in dose calculations.The dose calculation ability of pseudo-kVCT is comparable to that of MVCT,providing a possibility for the application of pseudo-kVCT images in image-guided adaptive radiotherapy.

Objective:To apply deep neural networks to predict high-precision dose distribution in volume modulated arc therapy (VMAT) plans for non-small cell lung cancer (NSCLC) patients.Methods:This study developed a U-shaped network called MHA-resunet, which incorporated a large kernel dilated convolution module and a multi-head attention module. The model was trained from 151 VMAT plans of NSCLC patients. CT images, planning target volume (PTV) and organs at risk (OARs) were fed into the independent input channel. The dose distribution was taken as the output to train the model. The performance of this network was compared with that of several commonly used networks, and the networks′performance was evaluated based on the voxel-level mean absolute error (MAE) within the PTV and OARs, as well as the error in clinical dose-volume metrics.Results:The MAE between the dose distribution predicted by MHA-resunet network and the manually planned dose distribution within the PTV area was 1.51 Gy, and the D98 and D95 errors in the PTV area were both < 1 Gy. Compared with the other three commonly used networks, the dose error of the MHA-resunet was the smallest in the PTV area and in OARs except for the heart. Conclusions:The proposed MHA-resunet network improves the receptive field to learn the relative spatial relationship between the PTV area and the OARs, enabling accurate prediction of dose distribution in NSCLC patients undergoing VMAT radiotherapy.
