ObjectiveTo assess the therapeutic effectiveness and safety of the traditional Chinese medicine compound Shenlong decoction in addressing the symptoms of pulmonary deficiency and stasis in patients with idiopathic pulmonary fibrosis （IPF）. MethodsSixty eligible patients with lung deficiency and collateral stasis syndrome of IPF were randomly assigned to the observation （30 patients） and control groups （30 patients）. All patients underwent standard Western medical therapy. Additionally，the observation group received Shenlong decoction granules，while the control group received a placebo. Both treatments were packaged in four doses of 10.5 g each，taken twice daily for three months. The indexes of the patients during the treatment cycle were observed，and the main indexes include traditional Chinese medicine （TCM） syndrome scores and 6 min walk test （6MWT）. The secondary indexes include pulmonary function test ［actual value/expected value of total lung volume （TLC%），actual value/expected value of vital capacity（FVC%），actual/predicted diffusing capacity of the lung for carbon monoxide（DLCO%），actual/predicted forced expiratory volume in one second （FEV₁%），and FEV₁/ forced vital capacity （FVC）］，blood gas analysis ［arterial blood diathesis partial pressure of oxygen （PaO₂），partial pressure of carbon dioxide （PaCO₂），and arterial oxygen saturation （SaO₂）］，serum inflammatory factors ［transforming growth factor-β₁ （TGF-β₁），interleukin-4 （IL-4），interleukin-13 （IL-13），interleukin-12 （IL-12），and gamma-interferon （IFN-γ）］，and quality of survival evaluation ［St George's Respiratory Questionnaire （SGRQ） score］. The patients' clinical manifestations were determined at the end of the treatment， and the occurrence of adverse events was recorded. ResultsA total of 53 patients completed the study，comprising 27 in the control group and 26 in the observation group. Upon completion of the treatment period，the control group achieved a total effective rate of 33.33% （9/27），whereas the observation group demonstrated a total effective rate of 53.85% （14/26），which was statistically superior to the control group （χ²=4.034，P<0.05）. After the treatment，the TCM syndrome scores，6MWT，DLCO%，FEV₁%，PaO₂，PaCO₂，TGF-β₁，IL-4，IL-13，IL-12，and IFN-γ in the two groups were all significantly improved （P<0.01）. Compared with those in the control group after treatment at the same period，the TCM syndrome scores，6MWT，PaO₂，and PaCO₂ were significantly improved in the observation group after 60 days and 90 days of medication （P<0.01）. Three months after the end of medication，the SGRQ score in the observation group showed significant improvement when compared to that in the control group （P<0.05），and no severe adverse events were reported during the follow-up period. ConclusionCompound Shenlong decoction can alleviate clinical symptoms such as shortness of breath and wheezing in patients with lung deficiency and collateral stasis syndrome of IPF，enhance exercise tolerance，improve the quality of life，and have certain potential advantages in improving pulmonary function.

Objective: To develop a non-invasive predictive model for coronary artery stenosis severity based on adaptive multi-modal integration of traditional Chinese and western medicine data. Methods: Clinical indicators, echocardiographic data, traditional Chinese medicine (TCM) tongue manifestations, and facial features were collected from patients who underwent coronary computed tomography angiography (CTA) in the Cardiac Care Unit (CCU) of Shanghai Tenth People's Hospital between May 1, 2023 and May 1, 2024. An adaptive weighted multi-modal data fusion (AWMDF) model based on deep learning was constructed to predict the severity of coronary artery stenosis. The model was evaluated using metrics including accuracy, precision, recall, F1 score, and the area under the receiver operating characteristic (ROC) curve (AUC). Further performance assessment was conducted through comparisons with six ensemble machine learning methods, data ablation, model component ablation, and various decision-level fusion strategies. Results: A total of 158 patients were included in the study. The AWMDF model achieved excellent predictive performance (AUC = 0.973, accuracy = 0.937, precision = 0.937, recall = 0.929, and F1 score = 0.933). Compared with model ablation, data ablation experiments, and various traditional machine learning models, the AWMDF model demonstrated superior performance. Moreover, the adaptive weighting strategy outperformed alternative approaches, including simple weighting, averaging, voting, and fixed-weight schemes. Conclusion The AWMDF model demonstrates potential clinical value in the non-invasive prediction of coronary artery disease and could serve as a tool for clinical decision support.

Objective:To develop and evaluate the efficacy and safety of a three-dimensional (3D) digestive endoscope for gastric endoscopic submucosal dissection (ESD) through animal experiments.Methods:Two Dutch pigs were utilized from the Zhengzhou University Animal Experiment Center for the study. ESD procedures were performed by two senior endoscopists, one using 3D glasses and the other utilizing a 3D high-definition head display. The success of ESD was assessed based on predefined criteria, including completion of surgical steps, complete detachment of the presumptive lesion, and effective bleeding control during and after the surgery. The number of successful procedures and incidences of perforation were recorded. The stereoscopic experience of the endoscopists, including both the primary endoscopist and the assistant, was also evaluated. Furthermore, the assessment encompassed any reported symptoms of eye discomfort, such as eye fatigue, ocular pain, and blurred vision. Additionally, the confidence level of the endoscopists in the mechanical aspects of the operation, as well as encountered issues during the endoscopic procedures, were documented.Results:Two ESD were successful and no perforation occurred. Feedback from endoscopists suggested that 3D digestive endoscopy offered clear images with enhanced three-dimensionality during surgery, clear sense of distance and layering, allowing for a precise judgment of bleeding points, which surpassed 2D capabilities. No eye discomfort was experienced by endoscopists or assistants during or after the procedures. While endoscopists exhibited high confidence in 3D digestive endoscopy, they noted issues with image blurring when the camera was positioned less than 10 mm from the gastrointestinal tract wall.Conclusion:Preliminary results show that 3D digestive endoscopes can provide excellent stereo imaging, improved positioning accuracy, and safety during live animal stomach ESD procedures, without significantly increasing endoscopists' eye discomfort. Nevertheless, efforts are needed to address image blurring concerns when the camera is close to the gastrointestinal tract wall.

Objective:To construct an analytic method aimed at the characteristics of the commonly method of supplementing and pouring of acupuncture based on the analysis and modeling of ultrasound images around acupoint region in the process of acupuncture.Methods:A total of 7 healthy subjects who underwent physical examination in Beijing Zhongguancun Hospital from June,2022 to June,2023 were selected,and their Kongzui acupoints were acupunctured by 10 acupuncturists with associate senior title as 4 kinds of acupuncture manipulations included reinforcing by twisting and rotating(RFTR),reducing by twisting and rotating(RDTR),reinforcing by lifting and thrusting(RFLT),and reducing by lifting and thrusting(RDLT).The B-ultrasound diagnostic device was used to collect the images of muscle and fascial tissue below the acupoint,so as to construct the model of images.The definition of virtual acupuncture point was adopted to study the regulation of perturbation of subcutaneous tissue that was caused after the skin was acupunctured by needle.The change regulation of the virtual acupuncture point of muscle bundle below skin at Zuikong acupoint of subjects was analyzed.Results:The difference value of average absolution value between peak and trough of the trajectory of virtual acupuncture point of twisting and rotating was 0.066±0.045,and the average value of amplitude of this method was less than that(0.428±0.276)of lifting and thrusting method,and the twisting and rotating method was uniform and symmetrical,and there was difference between two kinds of acupuncture methods.The characteristics of computer graphics was used to qualify the work effect of lifting and thrusting,and reinforcing and reducing,which showed the heavy insertion and light lifting of RFLT,and showed heavy lifting and light insertion of RDLT,thus distinguished the two methods[(RFLT)and(RDLT)].Conclusions:The ultrasound imaging and computer graphics can be used to analyze the regularity of the common"reinforcing and reducing"method of acupuncture and moxibustion.

ObjectiveTo analyze the quantity-quality transfer of standard decoction of Ginseng Radix et Rhizoma（GRR） decoction pieces produced by fresh and traditional cutting， and to provide reference for quality control and application development of the decoction pieces produced by fresh cutting. MethodTen batches of representative GRR decoction pieces produced by fresh and traditional cutting and their standard decoctions were prepared by standard process， and high performance liquid chromatography（HPLC） fingerprint of the standard decoction was established and performed on an Agilent EC-C₁₈ column（4.6 mm×150 mm， 2.7 μm） with acetonitrile（A）-0.1% phosphoric acid aqueous solution（B） as the mobile phase for gradient elution（0-23 min， 18%-21%A； 23-35 min， 21%-28%A； 35-80 min， 28%-32%A）， and the detection wavelength was 203 nm. Then similarity evaluation， principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA） of fingerprint of the standard decoction were performed to screen the differential components with variable importance in the projection（VIP） value>1. Quantitative analysis was carried out on the screened known differential components， and combined with the indicators of the dry extract rate and the transfer rate， to explore the differences in the quantity-quality transfer between the standard decoction of GRR decoction pieces produced by fresh and traditional cutting. ResultThe fingerprint similarity of the standard decoction of GRR decoction pieces produced by fresh and traditional cutting was more than 0.950， and 18 common peaks were identified， including 9 identified common peaks. The results of PCA and PLS-DA showed that there were some differences in the contents of index components between the two standard decoctions. The contents of ginsenoside Rg₁， Re and Ro in GRR decoction pieces produced by fresh cutting were higher than those in traditional decoction pieces， while the contents of ginsenoside Rb₁， Rc ， Rb₂ and Rd were lower than those in traditional decoction pieces. The contents of ginsenoside Rg₁， Re， Rb₁ and Ro in the standard decoction of GRR decoction pieces produced by fresh cutting were higher than those in the standard decoction of traditional decoction pieces， while the contents of ginsenoside Rc ， Rb₂ and Rd were comparable between the two standard decoctions. Compared with the standard decoction of the traditional decoction pieces， the average transfer rates of ginsenoside Rg₁， Rb₁， Rc， Rb₂ and dry extract rate of the standard decoction of GRR decoction pieces produced by fresh cutting were significantly increased（P<0.05）， and the average transfer rate of ginsenoside Re and Rd also increased， but the difference was not statistically significant. ConclusionThe dry extract rate， content and transfer rate of index components of standard decoction of GRR decoction pieces produced by fresh cutting are better than those of the standard decoction of traditional decoction pieces， which can provides data support for the subsequent clinical application of fresh cutting products.

MethodsFifty SD rats were randomly divided into a blank group， a model group， a Danshen Pill （丹参滴丸） group， and a low- and high-dosage Danggui Sini Granules group， with 10 rats in each group. Except for the blank group， the rat model of coronary heart disease with cold congealing and blood stasis syndrome was established by repeated cold stimulation at low temperature combined with intraperitoneal injection of posterior pituitary hormone in all other groups. In the 6th week of modelling， 0.073 g·kg^-1·d^-1 of compound Danshen Pill was given to the Danshen Pill group， 20.2 and 40.4 g·kg^-1·d^-1 of Danggui Sini Granules were given to the low- and high-dose Danggui Sini Granules groups， respectively， and 0.2 ml/10 g of sterile water was given to the blank group and the model group， all for 2 consecutive weeks. The general conditions of the rats were recorded， and the body mass was compared weekly. At the end of the intervention， electrocardiogram， blood rheological indexes， including whole blood low-cut viscosity， whole blood high-cut viscosity， erythrocyte aggregation index， and cardiac index were detected to evaluate the effect of the medication， and HE staining was used to observe the myocardial histopathological changes， TUNEL staining to detect the apoptotic situation of cardiomyocytes， and ELISA to detect the serum thyroid-stimulating hormone （TSH）， free triiodothyronine （FT₃）， free tetraiodothyronine （FT₄） levels and thromboxane B₂ （TXB₂）， 6-keto-prostaglandin F1α （6-Keto-PGF_1α）， endothelin 1 （ET-1）， and nitric oxide （NO） levels. ResultsCompared with the blank group at the same time point， the body mass of rats in the remaining groups decreased at all time points （P＜0.05 or P＜0.01）； compared with the model group at the same time point， the body mass of rats in high-dose Danggui Sini Granules group and Danshen Pill group increased at the 6th and 7th weeks （P＜0.05 or P＜0.01）. In the blank group， the S-T segment of the electrocardiogram was close to the isoelectric line， the myocardial structure was regular， the fibres were closely arranged， and the nuclei of the cells were intact and neatly aligned； in the model group， the S-T segment of the electrocardiogram significantly elevated， and the arrangement of the myocardial fibres was obviously disordered， with myocardial cells appearing to be swollen， necrotic， and infiltrated by inflammatory cells， and the apoptosis-positive cells of the cardiac muscle cells obviously increased； in each of the medication groups， the electrocardiogram had a lowered S-T segment， and myocardial fibres were aligned， myocyte structure and morphology were improved， inflammatory cells reduced， and the number of apoptosis-positive cells significantly reduced. Compared with the blank group， the cardiac index， whole blood high cut viscosity， whole blood low cut viscosity， erythrocyte aggregation index increased in the model group， and the serum levels of TSH， FT₃， FT₄， NO， 6-Keto-PGF_1α significantly reduced， and the levels of ET-1 and TXB₂ significantly increased （P＜0.05 or P＜0.01）. Compared with the model group， the levels of cardiac index， whole blood high cut viscosity， whole blood low cut viscosity， erythrocyte aggregation index， ET-1 and TXB₂ significantly decreased and the levels of NO and 6-Keto-PGF_1α significantly increased in each medication group， and the serum levels of TSH， FT₃， and FT₄ elevated in the high-dose Danggui Sini Granules group and Danshen Pill group （P＜0.05 or P＜0.01）. The serum TSH level of rats in the low-dose Danggui Sini Granules group was lower than that in Danshen Pill group and the high-dose Danggui Sini Granules group （P＜0.01）. ConclusionDanggui Sini Granules have the effect of alleviating myocardial injury in coronary heart disease with cold congealing and blood stasis syndrome， and its mechanism may be related to reducing myocardial cell apoptosis， improving energy metabolism， and regulating the level of vasoactive factors.

Methods: Data of TCM indicators (tongue, facial, and pulse diagnostics) and clinical parameters from patients diagnosed with CHD at the Cardiology Department of Shanghai Baoshan Hospital of Integrated Traditional Chinese and Western Medicine, from October 3, 2023 to March 15, 2024, were collected. Important variables were identified using importance screening and correlation analysis with CHD risk factors and laboratory markers. Six machine learning models including logistic regression (LR), decision tree (DT), support vector machine (SVM), k-nearest neighbors (KNN), random forest (RF), and gradient boosting (GB), were applied to evaluate the risk of coronary artery obstruction by combining clinical and TCM data of CHD. Model performance was assessed using metrics such as accuracy, precision, and recall, with reliability validated through ten-fold cross-validation. Results: A total of 288 patients were included in the study. Fifteen clinical risk factors, including body mass index (BMI), myoglobin, and alcohol consumption history, were incorporated into the diagnostic models. The KNN model showed good performance when combining clinical data with tongue and facial data. The SVM model performed well when clinical data was combined with pulse data. Among all the models, the KNN model with 10-fold cross-validation, which integrates the three types of TCM diagnostic data (tongue, face, and pulse) with clinical data, performs the best (accuracy: 0.837, precision: 0.814, and recall: 0.809). Conclusion Incorporating TCM diagnostic data can enhance the accuracy of coronary artery obstruction risk assessment. The KNN prediction model that integrate tongue, facial, and pulse data performs the best and can be recommended as a clinical decision support tool.

OBJECTIVE To investigate the protective effect of Tibetan medicine Sanguo decoction on hyperlipidemic rats based on the Nrf2/HO-1 signaling pathway and its related mechanisms. METHODS Forty-eight male SD rats were randomly divided into six groups: the normal control group, the model control group, the simvastatin group(3.5 mg·kg−1), and the Tibetan medicine Sanguo decoction low, medium, and high dose groups(0.43 , 0.86 , 1.72 g·kg−1), with eight rats in each group. The normal control group was fed a basal diet, and the remaining groups were fed the H10060 high-fat diet to prepare a hyperlipidemic rat model. At the same time, each treatment group was given corresponding drugs by gavage once a day. The normal control group and model control group were given an equal volume of physiological saline(once a day) by gavage for 6 consecutive weeks. After 6 weeks, serum levels of lipids[totalcholesterol(TC), triglyceride(TG), low density lipoprotein(LDL) and high density lipoprotein(HDL)] and oxidative parameters[malondialdehyde(MDA), superoxide dismutase(SOD), and glutathione(GSH)] were measured by reagent kit. Nuclear factor erythroid 2-related factor 2(Nrf2), heme oxygenase 1(HO-1), Keap1, and quinone oxidoreductase(NQO1) protein expression in liver tissues were analyzed by Western blotting. The correlation of lipid and oxidative indices was investigated by person correlation. RESULTS Compared with the normal control group, the model control group showed a significant increase in body weight, significantly higher serum levels of TC, TG, LDL, and MDA, significantly lower serum levels of HDL, and significantly lower SOD and GSH activity. Compared with the model control group, each administration group showed a decrease in body weight and serum TC, TG, LDL, and MDA levels. In comparison with the model control group, the body weight was reduced, the serum levels of TC, TG, LDL, and MDA were significantly lower, the serum levels of HDL were significantly higher, and the SOD and GSH activities were significantly higher. Keap1 protein level expression was significantly up-regulated compared with the normal control group, and Nrf2, HO-1, and NQO1 protein level expression were significantly down-regulated in the model control group. Keap1 protein level expression was significantly down-regulated compared to the model control group, and Nrf2, HO-1, and NQO1 protein level expression were significantly up-regulated in the liver tissues of low and high doses of Sanguo decoction. The expressions of Nrf2, HO-1, and NQO1 were significantly up-regulated. Correlation analysis showed that TG was negatively correlated with SOD, HO-1, and NQO1, and positively correlated with Keap1, while TC was negatively correlated with SOD, HO-1, GSH, and Nrf2, and positively correlated with Keap1 and MDA. CONCLUSION The Tibetan medicine Sanguo decoction can improve body weight and blood lipid levels in hyperlipidemic rats, and the mechanism may be related to the regulation of the Nrf2/HO-1 signaling pathway and the improvement of oxidative stress.

ObjectiveTo analyze and determine the differential components of freeze-dried and sun-dried Panacis Quinquefolii Radix（PQR）， and to compare the differences in their pro-angiogenic activities. MethodFingerprints of freeze-dried and sun-dried PQR were established based on ultra performance liquid chromatography（UPLC）， and chemometrics methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were combined to determine the differential saponin composition of the two decoction pieces， and six representative saponins were selected and their contents in freeze-dried and sun-dried PQR were determined by UPLC. Transgenic zebrafish line Tg（fli1a∶EGFP） embryos fertilized for 24 h were selected， and different doses of 70% methanol extracts of freeze-dried and sun-dried PQR（10， 30 mg·L^-1） were used to intervene in normal zebrafish and in a zebrafish model of intersegmental vascular（ISV） injury induced by vascular endothelial growth factor（VEGF） receptor tyrosine kinase inhibitor Ⅱ（PTK787）， then the development of subintestinal vein（SIV） and ISV of zebrafish was observed， SIV diameter， mean number of crossings and mean number of germinations were determined， and the ISV vascular index was calculated， in order to compare the pro-angiogenic activities of the two decoction pieces. ResultThe similarity of the fingerprints of freeze-dried and sun-dried PQR decoction pieces was>0.950， and 17 common peaks were identified， of which 6 common peaks were designated as peak 6（ginsenoside Rg₁）， peak 7（ginsenoside Re）， peak 8（ginsenoside Rb₁）， peak 11（ginsenoside Rc）， peak 13（ginsenoside Rb₂）， and peak 16（ginsenoside Rd）， respectively. A total of 11 differential saponin components were screened by PCA and OPLS-DA， indicating that there were some differences in the contents of the components in the two decoction pieces. The results of determination showed that the contents of ginsenosides Rg₁， Re， Rb₁ and Rb₂ in freeze-dried PQR were higher than those in sun-dried PQR， while the contents of ginsenosides Rc and Rd were lower than those in sun-dried PQR（P<0.05， P<0.01）. In the study of the pro-angiogenic effect on normal zebrafish embryos， compared with the blank group， and the SIV vessel diameter， mean germination rate and mean crossover rate were significantly higher in the high-dose groups of freeze-dried and sun-dried PQR（P<0.01）， and the vessel diameter， mean numbers of crossings and germinations in the freeze-dried PQR group were higher than those of the sun-dried PQR group（P<0.05）. In the study of the pro-angiogenic effect on zebrafish embryos with ISV injury， the development of ISV in the model group was significantly inhibited when compared with the blank group， compared with the model group， different dose groups of freeze-dried and sun-dried PQR could promote the growth and sprouting of ISV， and the number of normal blood vessels in the freeze-dried PQR group was significantly higher than that in the sun-dried PQR group at the same dosage（P<0.05）. ConclusionFreeze-drying can effectively avoid the loss and secondary transformation of ginsenosides in PQR， and its angiogenic activity is better than that of sun-dried PQR， which can provide a reference for the production and development of high-quality PQR decoction pieces.
