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.

Objective: To systematically evaluate the association between random urinary electrolyte levels and hypertension among children and adolescents in Guizhou Province, so as to provide evidence for region specific dietary guidance and interventions. Methods: In 2023, a total of 2 480 children and adolescents aged 6 to 17 years were recruited from a nine-year coherent style school in Guizhou Province in a children health cohort, with follow ups conducted in 2024 and 2025. Random urine samples were collected to measure urinary sodium, potassium, calcium, and chloride, and the urinary sodium to potassium ratio (Na/K) was calculated. The diagnosis of hypertension was based on the criteria established by the Chinese Guidelines for Hypertension Prevention and Treatment (2024 revised edition) and relevant research. Linear mixed models and multinomial Logistic regression were used to assess the associations of urinary electrolytes with systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and the risk of hypertension. Results: At baseline, SBP, DBP, and MAP were 102.33 (94.33, 110.33), 61.33 (56.33, 67.00) and 75.22 (69.67, 81.33)mmHg among children and adolescents, respectively. After adjusting for potential confounders and two follow-ups, higher urinary Na/K ratio was positively associated with higher of SBP ( β=0.054, 95%CI =0.028- 0.081 ) and MAP ( β=0.038, 95%CI =0.010-0.066), as well as higher risks of hypertension ( OR=1.248, 95%CI =1.006-1.548) (all P <0.05). Higher of urinary chloride levels were positively associated with higher of SBP ( β=0.088, 95%CI = 0.009- 0.167), whereas higher of urinary potassium (SBP: β=-0.062, 95%CI =-0.096 to -0.028; MAP: β=-0.041, 95%CI = -0.078 to -0.005) and calcium levels (SBP: β=-0.036, 95%CI =-0.065 to -0.007) were negatively associated with blood pressure (all P < 0.05 ). Conclusion The urinary Na/K, as a comprehensive electrolyte marker, more stably reflects sodium load and excretory pressure in children and adolescents, and may serve as an early predictor of hypertension risk.

Objective: To establish a rapid, accurate, and decentralized workflow for bacterial whole-genome sequencing (WGS) and risk profiling within the shelf-life of platelet concentrates, and to characterize the species, virulence, antimicrobial resistance (AMR), and immune evasion mechanisms of co-existing bacteria in qualified platelet products, thereby providing a scientific basis for transfusion safety assessment. Methods: Three units of platelet concentrates, which tested negative by routine bacterial screening, were collected from the Chengdu Blood Center between May and June 2025. Samples were enriched at 37℃under six aerobic and nine anaerobic conditions for 7 days. Using a culturomics strategy, aliquots were plated for isolation on days 1, 3, 5, and 7 to obtain cultivable isolates, with negative culture controls included to exclude contamination. High-molecular-weight genomic DNA was extracted via mechanical grinding, purified, and size-selected. Sequencing libraries were constructed and sequenced on the G-seq500 single-molecule nanopore sequencing platform. Genomes were assembled using Flye and polished with NextPolish, with quality evaluated by BUSCO and CheckM. Taxonomic identification was performed using GTDB-Tk. Functional annotation and database comparisons were conducted to analyze virulence factors, AMR genes, and genes related to immune evasion and environmental adaptation. Results: Viable bacteria were successfully isolated from all three qualified platelet units within their shelf life. The isolates were identified as Bacillus albus, Niallia taxi, and Staphylococcus warneri. Nanopore sequencing generated 92 227-109 813 reads (totaling 680-758 Mb) with an N50 of 7 625-8 584 bp and Q20/Q30 scores of 97%/93%, respectively. All three genomes were assembled into complete circular chromosomes with 1-3 plasmids, achieving >93% completeness. Functional analysis revealed that B. albus carried multiple hemolysins, metalloproteases, and multidrug resistance genes, indicating the highest potential pathogenicity and AMR risk. S. warneri exhibited a typical multidrug resistance profile and regulatory network characteristic of coagulase-negative staphylococci, suggesting intermediate virulence. N. taxi harbored few canonical virulence factors and lacked functional AMR determinants, presenting a "low-virulence, low-resistance" profile. Notably, all three strains were enriched in genes encoding antimicrobial peptide resistance systems (e.g., dltABCD, mprF, GraRS, BceAB) and antioxidant enzymes, suggesting a strong capacity to withstand immune stress in the blood environment. Conclusion: Viable bacteria can be recovered from qualified platelet concentrates that test negative by routine screening. Nanopore WGS enables rapid strain-level identification and comprehensive risk profiling of virulence, resistance, and immune adaptation traits. The functional repertoires of these "co-existing" isolates range from environmental adaptation to potential pathogenicity, representing an underappreciated risk for transfusion-transmitted infections in susceptible recipients.

This paper discussed the differentiation and treatment of chemotherapy-induced nausea and vomiting （CINV） in traditional Chinese medicine， based on the theory of "yin qi descends， while all yang qi ascends” from Inner Canon of Yellow Emperor （《黄帝内经》）. The core pathogenesis of CINV is attributed to chemotherapy-induced injury to the middle jiao （焦）， resulting in the separation of yin and yang and loss of their mutual communication. Acute and explosive CINV is often characterized by "all yang qi ascends"， with stomach yang constraint transforming into fire， and qi counterflow leading to vomiting， which can be treated by unblocking stomach yang， draining fire and scattering the counterflow， with Huoxiang Zhengqi Powder （藿香正气散） and medicinals of clearing function. For delayed cases， which are often due to "yin qi descends"， and the accumulation of turbid yin obstructs and constrains the deficient yang， the treatment should focus on promoting qi flow to eliminate turbidity， unblocking and boosting yang qi， and Chengqi-series Formulas （承气类方） or Xiao Banxia Decoction （小半夏汤） can be considered. Refractory and anticipated cases usually involve stomach-kidney deficiency and zang-fu （脏腑） organs disharmony， making yin and yang difficult to restore balance， for which the treatment should focus on nourishing both the stomach and kidneys and harmonize the zang-fu organs， with formulas such as Fuzi Lizhong Decoction （附子理中汤） or Xiaoyao Powder （逍遥散） modified as appropriate.

Colorectal cancer is a common and malignant tumor in the digestive tract. Invasion and metastasis of cancer cells are key factors leading to the high mortality rate and postoperative recurrence of colorectal cancer. Chemotherapy is the main treatment method for preventing recurrence of this disease. However， there are many toxic side effects in clinical application， which seriously hinder the treatment process. Therefore， it is imperative to search for efficient and low-toxicity drugs. Traditional Chinese medicine （TCM） has a long history of treating colorectal cancer and offers advantages such as safety， effectiveness， multiple targets， multiple pathways and minimal toxic side effects， which have made it increasingly popular worldwide. According to TCM， the pathogenesis of colorectal cancer is rooted in both deficiency and excess. TCM formulas mainly focus on tonifying the body to address the invasion and metastasis of colorectal cancer， such as Jianpi compound， Jianpi Xiaoai decoction， and Bushen Jiedu Sanjie decoction. TCM monomers， such as emodin， berberine， and tanshinone， mainly focus on clearing heat and removing toxin， circulating blood and transforming stasis， and resolving swelling and dispersing nodules. Signaling pathways play a crucial role for analyzing invasion and metastasis， and research has shown that pathways such as Wnt/β-catenin， phosphatidylinositol-3 kinase/protein kinase （PI3K/Akt）， Janus kinase 2/signal transduction and transcription activating factor 3 （JAK2/STAT3）， nuclear factors-κB （NF-κB）， vascular endothelial growth factor （VEGF） play important roles in the invasion and metastasis of colorectal cancer. The invasion and metastasis of colorectal cancer can be inhibited via regulating the key proteins and related factors in these pathways. In this review， we searched various literature databases， such as PubMed， China National Knowledge Infrastructure （CNKI）， and VIP， using keywords such as "colorectal cancer"， "signaling pathway"， "invasion and metastasis"， and "traditional Chinese medicine"， to summarize and analyze the relevant pathways of TCM compounds and monomers against invasion and metastasis of colorectal cancer published in the past five years. The review aims to provide new insights and references for in-depth research on the therapy for invasion and metastasis of colorectal cancer and new drug development.

Objective:To summarize domestic and foreign transitional readiness assessment tools for adolescents with chronic diseases and analyze the current status of their application in the clinic, so as to provide references for healthcare professionals to select appropriate tools.Methods:China National Knowledge Infrastructure, Wanfang Data, VIP and China Biomedical Literature Database, PubMed, Web of Science, Embase, Medline, CINAHL, Cochrane Library and scholar.google.com were searched for literature related to the assessment tools of transition readiness in adolescents with chronic illnesses from inception to March 29, 2024. Two researchers independently screened the literature and extracted the data.Results:A total of 491 articles were initially retrieved and 24 were included, involving a total of 8 transitional readiness assessment tools for adolescents with chronic diseases, including the Transition Readiness Assessment questionnaire, the University of North Carolina TRxANSITION Scale, Am I ON TRAC for adult care? Questionnaire, Transition Questionnaire, Self-Management and Transition to Adulthood with Rx=Treatment Questionnaire, Good 2 Go Questionnaire, State Assessment Questionnaire for Transition, and Self-assessment Scale of Transition Readiness for Adolescents. The Transition Readiness Assessment questionnaire and Self-Management and Transition to Adulthood with Rx=Treatment Questionnaire have good reliability and validity, comprehensive evaluation, wide applicability, simple use, and are suitable for clinical use.Conclusions:The quality of existing tools for assessing transitional readiness of adolescents with chronic diseases is mixed. The Transition Readiness Assessment questionnaire and Self-Management and Transition to Adulthood with Rx=Treatment Questionnaire are more appropriate options in the clinic, but they still need to be improved. Future studies need to continue to introduce tools to assess transitional readiness for chronic diseases in adolescents and develop localized assessment tools.

Objectives:To compare the biomechanical outcomes of six different screw reinforcement methods for posterior lumbar pedicle screw augmentation technique in osteoporotic vertebrae through finite element analysis,and provide a reference for the optimization and selection of internal fixation screws.Method:The lumbar CT scan data from seven males without lumbar pathologies or surgical history were obtained.Age:68.0±4.9 years(60-75),height:171.7±3.2cm(168-176),weight:63.6±3.2kg(59-68).Continuous thin-layer scanning was performed using a 64-slice spiral CT to obtain DICOM images.The L3 vertebral 3D models were reconstructed using Mimics 21.0 software,after optimizing for surface geometry in Geomagic Wrap 2021,seven models of screw were designed and assembled in SolidWorks 2023.Screws were categorized into seven groups based on reinforcement methods:Group A(Control group,no reinforcement),Group B(increasing thread outer diameter),Group C(decreasing pitch),Group D(decreasing the part of pitch contacted cortical bone),Group E(bone cement reinforcement),Group F(penetrating the opposite cortex),and Group G(cortical bone tra-jectory screws).49 finite element models(7 screw types × 7 vertebrae)were established.After material property assignments based on the data from prior research literature,the Static Structural Analysis module of Ansys Workbench 2023 was employed to simulate axial pull-out experiments on the seven established finite element models.The pull-out displacement under an axial tension of 1,200N and the maximum equivalent stress when the screw was damaged were analyzed.Intergroup comparisons employed one-way ANOVA,with indepen-dent-sample t-tests for experimental vs.control group comparisons.Results:The maximum displacements of Groups A-G were 0.142±0.029mm,0.138±0.031mm,0.144±0.032mm,0.139±0.027mm,0.119±0.024mm,0.126±0.028mm,0.040±0.007mm,respectively.No statistically significant differences were observed between Groups A to F(F=0.812,P=0.5489).Group G demonstrated a statistically significant difference compared to Group A(P＜0.001).The maximum equivalent stress of groups A-G were 264.0±7.6MPa,234.8±28.0MPa,245.5±17.5MPa,260.0±7.2MPa,279.7±14.3MPa,311.9±31.4MPa,432.6±87.5MPa.Compared with group A,group B decreased by 11.1％,and group C decreased by 7％,and the differences were statistically significan(P＜0.05);Group D wasn't significantly different from group A(P＞0.05);Compared with group A,groups E-G increased by 5.9％,18.1％and 63.9％,respectively,and the differences were statistically significant(P＜0.05).Conclusions:Differ-ent screw augmentation techniques demonstrated significantly different effects on axial pull-out strength.In-creasing the outer diameter of the screw or decreasing the total pitch will reduce the axial pull-out strength of the screw,and reducing the pitch in the cortical bone area has no obvious positive effect on increasing the holding force of screw.Bone cement reinforcement,increasing the screw length in penetrating contralateral cortical bone,and cortical bone trajectory screw can all significantly improve the axial anti-pullout effect of the screw,among which Cortical bone trajectory screw augmentation technique has the most significant effect.

Objective:To explore the association between A Body Shape Index (ABSI) and sarcopenia in Chinese older adults.Methods:Totally 1 728 participants in waves 1 and 3 of the China Health and Retirement Longitudinal Survey (CHARLS) were enrolled in this cohort-based cross-sectional analysis. ABSI was calculated by using anthropometric measurements from CHARLS. According to the Asian Working Group for Sarcopenia (AWGS) 2019 consensus update on sarcopenia, low muscle strength and low muscle mass were used as the diagnostic criteria for sarcopenia. Logistic regression and restricted cubic spline (RCS) were used to assess the relationship between ABSI and sarcopenia, and subgroup and interaction analyses were conducted to evaluate the influence of other factors on this association.Results:High ABSI showed a significant association with the risk of sarcopenia among older adults in China, and RCS analysis demonstrated a positive linear correlation between ABSI and sarcopenia. Additionally, the relationship of ABSI with sarcopenia was significantly modified by educational level and depressive status.Conclusion:ABSI, a novel anthropometric measure, serves as an effective threshold for assessing sarcopenia risk in the Chinese older population, providing a basis for developing clinical interventions and public health strategies for the prevention and early identification of sarcopenia.

Progesterone receptor membrane component 1(PGRMC1)is closely related to hormone therapy which belongs to the membrane-associated progesterone receptor(MAPR)family.A large number of in vitro experiments,in vivo animal experiments,clinical samples of breast cancer patients and blood studies showed that all synthetic progesterone(excluding natural progesterone and dydrogesterone)can promote the rapid proliferation of breast cancer cells overexpressing PGRMC1.In patients with breast cancer,PGRMC1 is significantly negatively correlated with tumor grade and prognosis,and PGRMC1 level in blood is positively correlated with PGRMC1 expression in breast cancer tissues,and PGRMC1 is superior to traditional tumor markers such as carcinoembryonic antigen(CEA),carbohydrate antigen(CA125),and CA153 in predicting early breast cancer.Therefore,PGRMC1 may serve as a predictive marker for identifying an elevated risk of breast cancer associated with menopausal hormone replacement therapy.
