Based on the theory of "sweet-flavored medicinals retaining and restoring body fluid"， this paper proposed that the core pathogenesis of hypercoagulable state in malignant tumors is qi deficiency and fluid consumption， blood stasis and vessels stagnation， which evolves dynamically according to the pattern "qi deficiency → fluid consumption → blood stasis". Accordingly， a staged treatment system is established with the general principle of "fortifying the middle jiao， restoring fluid and activating blood circulation". In the initial stage， invigorating the spleen and boosting qi to generate body fluid， targeting the onset of middle jiao deficiency and body fluid consumption； in the middle stage， nourishing yin and unblocking collaterals to facilitate body fluid circulation， addressing the disorder of body fluid transportation and collateral injury caused by internal dryness； in the late stage， consolidating yin and resolving blood stasis to retain body fluid， resolving yin impairment， fluid exhaustion， and binding of stasis and toxin. By regulating body fluid metabolism to improve the hypercoagulable state， this system is intended to provide insights for the prevention and treatment of hypercoagulable state in malignant tumors with traditional Chinese medicine.

Esophageal cancer （EC） is a highly prevalent malignant tumor in China. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， as one of the key oncogenic pathways， can promote the cell cycle progression， proliferation， migration， and invasion， induce chemoresistance， and inhibit apoptosis and autophagy of EC cells. Traditional Chinese medicine （TCM）， with the advantages of targeting multiple points with multiple components to delay cancer progression， can target the PI3K/Akt signaling pathway for EC treatment. This article preliminarily discusses the molecular mechanism and role of the PI3K/Akt signaling pathway in EC and elaborates on the specific targets and efficacy of TCM in treating EC through intervention in the PI3K/Akt signaling pathway in the past five years. TCM materials and extracts inhibiting the PI3K/Akt signaling pathway in EC include Borneolum， spore powder of Ganoderma lucidum without spore coat， extract of Celastrus orbiculatus， root extract of Taraxacum， and Bruceae Fructus oil emulsion. TCM active ingredients exerting the effect include flavonoids， terpenoids， saponins， phenols， polysaccharides， alkaloids， and other compounds. TCM compound prescriptions with such effect include Qige San， Huqi San， Xuanfu Daizhetang， Tongyoutang and its decomposed prescriptions， Liujunzi Tang， and Xishenzhi Formula. In addition， TCM injections such as Compound Kushen Injection and Kang'ai injection also inhibit the PI3K/Akt signaling pathway in EC. This paper summarizes the role of the PI3K/Akt signaling pathway in EC and the TCM interventions， aiming to provide reference for the research and clinical application of new drugs for EC.

ObjectiveTo explore the mediating effect of empathy ability on clinicians’ medical narrative competence and humanistic care quality， and to provide data support for the improvement of clinicians’ empathy ability， narrative competence， and humanistic care quality. MethodsEmploying a convenience sampling method， a questionnaire survey was conducted among clinicians in Hebei province using a general data questionnaire， the Chinese Physician Narrative Behavior Scale， the Chinese version of the Jefferson Scale of Empathy， and the Humanistic Care Quality Scale. SPSS 21.0 software was used to analyze the current situation and correlation of clinicians’ medical narrative competence， empathy ability， and humanistic care quality. Amos 26.0 software was utilized to construct the structural equation model， and the Bootstrap method was adopted to test this model. ResultsThe scores of clinicians’ medical narrative competence， empathy ability， and humanistic care quality were （84.436±11.939）， （106.058±18.936）， and （117.652±14.087）， respectively. There were significantly positive correlations between clinicians’ medical narrative competence and humanistic care quality （r = 0.530， P<0.01）， between empathy ability and humanistic care quality （r=0.416， P < 0.01）， as well as between medical narrative competence and empathy ability （r=0.176， P<0.01）. Clinicians’ medical narrative competence had a positive predictive effect on humanistic care quality （β = 0.649， P < 0.001）. The empathy ability of clinicians played a partial mediating role between medical narrative competence and humanistic care quality （β = 0.061， P < 0.001）， with a mediating effect size of 0.068， accounting for 8.59% of the total effect. ConclusionClinicians’ medical narrative ability， empathy ability， and humanistic care quality are all at a moderately high level. Empathy ability plays a partially mediating role between medical narrative ability and humanistic care quality. It is suggested that clinicians’ medical narrative competence should be improved through various ways， thereby improving their humanistic care quality.

By analyzing the understandings of water points (acupoints connected with the kidney) and its association with water (kidney), zangfu organs and meridian-collateral recorded in Suwen: Shuire Xue Lun (Discussion on Water and Heat Diseases in Plain Question), it is found that the recognition on the water points is different from that on water diseases in Huangdi Neijing (the Yellow Emperor 's Inner Classic). The recognition on the water points focuses on the core theory, "rooted at the kidney", to explain the water diseases. Besides, in association with the study on the connotation of "luo" in Huangdi Neijing, it is discovered that "yinluo" discussed in water points is actually the misunderstanding of "zang zhi yinluo" that means "the connection by the kidney". It is shown that the discussion of water points refer to the elaboration of zangfu organs and 57 acupoints connected with water (the kidney), rather than the theory of collaterals. The characteristics of these 57 acupoints involved and the related needling techniques provide a new approach to the treatment of zangfu diseases.

The diseases and pathological manifestations associated with chongmai (thoroughfare vessel) are the representative in the practical applications of chongmai theory. Elucidating this theory serves as a prerequisite of acupuncture and moxibustion therapy. Based on literature analysis, the diseases and clinical manifestations of chongmai recorded in the time of Huangdi Neijing (The Yellow Emperor's Inner Classic) were analyzed so as to reinterpret the diagnostic process, pathological characteristics, and clinical manifestations of disorders, and evaluate the value of chongmai theory. Chongmai diseases were identified from the palpation initially, known as the "palpation on abdominal pulse". The "qi reversion" of chongmai represents a typical clinical manifestation of chongmai diseases, such as ji (abdominal mass), jia (abdominal hematoma), and shan (hernia), occurring in different sites of the abdomen and in different pathological stages. A part of distribution of chongmai is considered in clinical manifestation, diagnosis and treatment of acupuncture and moxibustion. To emphasize the significance of chongmai in modern acupuncture-moxibustion theory and practice, the diagnostic and therapeutic patterns of the related disorders should be considered in clinical practice. The characteristics of chongmai are reflected in three aspects: qi, blood and abdomen, which are determined by both its inherent properties and the clinical manifestations of related diseases.

Objective : To explore the effect and mechanism of CD151 on vascular permeability by regulating vesicle internalization and recycling. Methods: Wild-type mice and CD151 knockout mice were divided into WT-con group, WT-model group, KO-con group and KO-model group, with 6 mice in each group. WT-model group and KO-model group were intraperitoneally injected with LPS to prepare sepsis ALI model, and WT-con group and KO-con group were intraperitoneally injected with phosphate buffer saline(PBS) as a control. 24 h after modeling, pulmonary vascular permeability was measured by Miles test. The siRNA silencing CD151 expression(si-CD151) and negative control si-NC were transfected into EA.hy 926 cells. The permeability of endothelial cell layer to FITC-dextran at different time points was observed under basic conditions and vascular endothelial growth factor-A(VEGF-A) stimulation conditions. Transcriptome sequencing of endothelial cells in si-CD151 group and si-NC group; the distribution and internalization of CD151 in each group were measured using immunofluorescence. Western blot and real-time quantitative RT-qPCR were used to detect the expression of VE-cadherin in si-CD151 groupand other groups. The distribution and internalization of VE-cadherin in each group were measured using immunofluorescence. Results : Miles experiment results indicated that dye exudation in lung tissue of WT-model group was significantly higher than that of WT-con group(P<0.01). The dye exudation in the lung tissue of KO-model group increased compared with WT-model group(P<0.05). The results of endothelial cell layer permeability test showed that the permeability of FITC-dextran in si-CD151 group was significantly higher than that in control group after VEGF-A stimulation for 30, 60 and 120 min(P<0.05). Transcriptome sequencing results suggested that CD151 in endothelial cells was closely related to vesicle-mediated transport. Compared with other groups, protein and mRNA levels of VE-cadherin in CD151 knockdown endothelial cells was significantly lower(allP<0.01). The immunofluorescence assay demonstrated that after VEGF-A stimulation, the decrease of CD151 expression significantly impaired the expression of VE-cadherin at cell-cell contacts and reduced the CD151-VE-cadherin colocalization in the perinuclear region compared with other groups. Conclusion The absence of CD151 affects the internalization and recycling of endothelial cell vesicles, affects the expression and internalization of VE-cadherin, and then influences vascular permeability.

BACKGROUND: Ferroptosis-related genes play a crucial role in regulating intracellular iron homeostasis and lipid peroxidation, and they are involved in the regulation of tumor growth and drug resistance. The expression of ferroptosis-related genes in tumor tissues can be used to predict patients' future survival times, aiding doctors and patients in anticipating disease progression. Based on the sequencing data of lung adenocarcinoma (LUAD) patients from The Cancer Genome Atlas (TCGA) database, this study identified genes involved in the regulation of ferroptosis, constructed a prognostic model, and evaluated the predictive performance of the model. METHODS: A total of 1467 ferroptosis-related genes were obtained from the GeneCards database. Gene expression profiles and clinical data from 541 LUAD patients were collected from the TCGA database. The expression data of all ferroptosis-related genes were extracted, and differentially expressed genes were identified using R software. Survival analysis was performed on these genes to screen for those with prognostic value. Subsequently, a prognostic risk scoring model for ferroptosis-related genes was constructed using LASSO regression model. Each LUAD patient sample was scored, and the patients were divided into high-risk and low-risk groups based on the median score. Receiver operating characteristic (ROC) curves were plotted, and the area under the curve (AUC) was calculated. Kaplan-Meier survival curves were generated to assess model performance, followed by validation in an external dataset. Finally, univariate and multivariate Cox regression analyses were conducted to evaluate the independent prognostic value and clinical relevance of the model. RESULTS: Through survival analysis, 121 ferroptosis-related genes associated with prognosis were initially identified. Based on this, a LUAD prognostic risk scoring model was constructed using 12 ferroptosis-related genes (ALG3, C1QTNF6, CCT6A, GLS2, KRT6A, LDHA, NUPR1, OGFRP1, PCSK9, TRIM6, IGF2BP1 and MIR31HG). The results indicated that patients in the high-risk group had significantly shorter survival time than those in the low-risk group (P<0.001), and the model demonstrated good predictive performance in both the training set (1-yr AUC=0.721) and the external validation set (1-yr AUC=0.768). Risk scores were significantly associated with the prognosis of LUAD patients in both univariate and multivariate Cox regression analyses (P<0.001), suggesting that this score is an important prognostic factor for LUAD patients. CONCLUSIONS This study successfully established a LUAD risk scoring model composed of 12 ferroptosis-related genes. In the future, this model is expected to be used in conjunction with the tumor-node-metastasis (TNM) staging system for prognostic predictions in LUAD patients.

OBJECTIVE: To compare the registration accuracy of cone beam computed tomography (CBCT) images while registering to virtual craniodentofacial patients based on soft tissue and the dentition registration method. METHODS: Virtual dentofacial patients out of 13 selected participants who needed CBCT scanning were established by impression with a registered-block impression (RBI) based on digital dental images, three-dimensional (3D) facial images and maxillofacial CBCT images. CBCT images were processed in the Mimics software program, establishing the craniofacial virtual patients based on CBCT images (CCTs). Registration between virtual patients from RBI and CCT, using the soft tissue in lower half face (STE) and dentition (DTN) as the reference area, respectively, forming two kinds of virtual craniofacial patients based on digital dental images, 3D facial images and skeletal images of CBCT (hiding the soft tissue and dental casts from CBCT). Three-dimensional deviation analysis was performed in the upper half face and lower half face of facial images from CBCT between two kinds of virtual craniodentofacial patients and compared with 3D facial images from RBI and recorded as root mean square error (RMSE). Paired-t test was used to compare the deviations of RMSEs between the upper and lower half of the face and the upper half of the face of facial images from CCT, respectively, between the two kinds of virtual craniodentofacial patients based on STE and DTN methods. RESULTS: Paired-t tests showed that there was no statistically significant difference between the upper and lower half faces of facial images from CCT between STE and DTN (P>0.05), but the deviation of RMSEs of the upper half face of facial images from CCT in STE was smaller than those in DTN [(1.696±0.420) mm vs. (1.752±0.424) mm, P < 0.01]. CONCLUSION The registration accuracy of CBCT registered in virtual craniodentofacial patients using soft tissue as the reference area was higher.

The disturbance of the human microbiota influences the occurrence and progression of many diseases. Live therapeutic bacteria, with their genetic manipulability, anaerobic tendencies, and immunomodulatory properties, are emerging as promising therapeutic agents. However, their clinical applications face challenges in maintaining activity and achieving precise spatiotemporal release, particularly in the harsh gastrointestinal environment. This review highlights the innovative bacterial functionalized encapsulation strategies developed through advances in physicochemical and biological techniques. We comprehensively review how bacterial encapsulation strategies can be used to provide physical barriers and enhanced adhesion properties to live microorganisms, while introducing superior material properties to live bacteria. In addition, this review outlines how bacterial surface coating can facilitate targeted delivery and precise spatiotemporal release of live bacteria. Furthermore, it elucidates their potential applications for treating different diseases, along with critical perspectives on challenges in clinical translation. This review comprehensively analyzes the connection between functionalized bacterial encapsulation and innovative biomedical applications, providing a theoretical reference for the development of next-generation bacterial therapies.

ObjectiveTo observe the effect of Yangxin Tongmai Formula （养心通脉方） by midnight-noon ebb-flow administration method for rat models of premature coronary heart disease （PCHD） with blood stasis syndrome， and to explore the possible mechanism of action from the perspective of DNA methylation differential gene expression. MethodsThere were 3 SD rats in each of the blank group， model group and Yangxin Tongmai Formula group， and the rats in the model group and Yangxin Tongmai Formula group were fed with high-fat chow plus vitamin D3 by gavage plus isoproterenol hydrochloride by subcutaneous injection to construct rat models of PCHD with blood stasis syndrome. After successful modelling， rats in Yangxin Tongmai Formula group were gavaged with 18 g/（kg‧d） of Yangxin Tongmai Formula， and rats in blank group and the model group were gavaged with 4 ml/（kg‧d） of 0.9% NaCl solution， and serum samples of rats in each group were collected for DNA methylation sequencing after 3 weeks to screen for the relevant DNA methylation differentiation genes. In addition， rats with successful modelling of PCHD with blood stasis were randomly divided into model group， Yangxin Tongmai Formula with midnight-noon ebb-flow administration method group ［18 g/（kg‧d） of Yangxin Tongmai Formula was gavaged twice in the heart channel period （12：00） and pericardium channel period （20：00）］， the Yangxin Tongmai Formula control group ［18 g/（kg‧d） of Yangxin Tongmai Formula was gavaged twice at 8：00 and 18：00］ and the Atorvastatin Calcium group ［atorvastatin calcium tablets solution 1.8 mg/（kg‧d） at the same intervention time as that in Yangxin Tongmai Formula control group］， and set up a blank group of 8 rats in each group. The model group and blank group were gavaged with 0.9% NaCl solution 4 ml/（kg‧d） for the same time as the Yangxin Tongmai Formula control group. After 3 weeks of gavage， the blood lipids ［including total cholesterol （TC）， low-density lipoprotein （LDL）， high-density lipoprotein （HDL）］ levels of rats in each group were detected； the HE staining of myocardial tissues and thoracic aorta was used to observe the pathomorphological changes； the levels of serum inflammation indexes ［tumour necrosis factor alpha （TNF-alpha）， lipopolysaccharide （LPS）， and interleukin 10 （IL-10）］ were detected； immunoprecipitation-realtime fluorescence quantitative PCR was used to detect the relative expression of cardiac tissue screening differential genes. ResultsThe genes screened for differentially methylated regions were calmodulin 2 （Calm2）， calcium voltage-gated channel subunit α1s （Cacna1s）， and phospholipase Cβ1 （Plcb1）. Compared with the blank group， rats in the model group showed elevated levels of TC， LDL， TNF-α and LPS， and decreased levels of HDL and IL-10 （P＜0.05 or P＜0.01）； HE staining showed obvious swelling of myocardial fibres， accompanied by a large number of inflammatory cell infiltration， and thickening of the inner wall of the aortic vessels with internal wall damage， which was visible as a large number of lipid cholesterol crystals and obvious inflammatory cell infiltration. Compared with the model group， the TC， LDL， TNF-α and LPS contents of rats in the Yangxin Tongmai Formula with midnight-noon ebb-flow administration method group， the Yangxin Tongmai Formula control group， and the atorvastatin calcium group all reduced， and the contents of HDL and IL-10 all elevated （P＜0.05）， with the improvement of myocardial tissue damage and the reduction of inflammatory infiltration， and the improvement of the damage of the inner lining of the thoracic aorta and the reduction of lipid infiltration. Compared with Yangxin Tongmai Formula control group， LDL， TNF-α and LPS contents reduced， and IL-10 contents increased in the midnight-noon ebb-flow administration method group （P＜0.05）. Compared with the model group， the relative expression of Calm2 and Plcb1 genes decreased and the relative expression of Cacna1s gene increased in Yangxin Tongmai Formula control group and the midnight-noon ebb-flow administration method group （P＜0.05）； compared with the Yangxin Tongmai Formula control group， the relative expression of Calm2 gene decreased and the relative expression of Cacna1s gene increased in the midnight-noon ebb-flow administration method group （P＜0.05）. ConclusionThe intervention of Yangxin Tongmai Formula in the heart channel period （12：00） and pericardium channel period （20：00） was more effective in improving the blood lipid level， inhibiting inflammation， and improving myocardial tissue damage in rats of PCHD with blood stasis syndrome， and Calm2 and Cacna1s genes may be the key targets of Yangxin Tongmai Formula in intervening the blood stasis syndrome of PCHD.
