"Weibing" is a fundamental concept in traditional Chinese medicine (TCM), representing a transitional state characterized by diminished self-regulatory abilities without overt physiological or social dysfunction. This perspective delves into the biological foundations and quantifiable markers of Weibing, aiming to establish a research framework for early disease intervention. Here, we propose the "Health Quadrant Classification" system, which divides the state of human body into health, sub-health, disease-susceptible state, and disease. We suggest the disease-susceptible stage emerges as a pivotal point for TCM interventions. To understand the intrinsic dynamics of this state, we propose laboratory and clinical studies utilizing time-series experiments and stress-induced disease susceptibility models. At the molecular level, bio-omics technologies and bioinformatics approaches are highlighted for uncovering intricate changes during disease progression. Furthermore, we discuss the application of mathematical models and artificial intelligence in developing early warning systems to anticipate and avert the transition from health to disease. This approach resonates with TCM's preventive philosophy, emphasizing proactive health maintenance and disease prevention. Ultimately, our perspective underscores the significance of integrating modern scientific methodologies with TCM principles to propel Weibing research and early intervention strategies forward.

Objective     To investigate the effects of different types of tricuspid regurgitation, implantation positions, and device models on the treatment outcomes of K-Clip for tricuspid regurgitation using numerical simulations. Methods     Three-dimensional reconstruction of the heart model was performed based on CT images. Two different regurgitation orifices were obtained by modifying the standard parameterized tricuspid valve leaflets and chordae tendineae. The effects of different K-Clip models at different implantation positions (posterior leaflet midpoint, anterior-posterior commissure, anterior leaflet midpoint, posterior septal commissure) were simulated using commercial explicit dynamics software Ls-Dyna. Conclusion     For the two types of regurgitation in this study, clipping at the posterior leaflet midpoint resulted in a better reduction of the regurgitation orifice (up to 75% reduction in area). Higher clamping forces were required for implantation at the anterior leaflet midpoint and posterior septal commissure, which was unfavorable for the smooth closure of the clipping components. There was no statistical difference in the treatment outcomes between the 18T and 16T K-Clip components, and the 16T component required less clamping force. Therefore, the use of the 16T K-Clip component is recommended.

BACKGROUND:The pedicle navigation template has many advantages,but there are still some problems.For example,poor soft tissue dissection leads to poor adhesion of the pedicle navigation template,resulting in screw path deviation;careful dissection of soft tissue to fit the pedicle navigation template leads to prolonged surgery time and increased bleeding;the design of the pedicle navigation template cannot predict the vertebral rotation and the impact of body position changes,resulting in the poor fitting. OBJECTIVE:To explore the utility of a new 5-point positioning point-contact pedicle navigation template in the case of scoliosis and complex pedicle. METHODS:A total of 20 patients with scoliosis and complicated pedicle admitted to the Department of Spinal Surgery,Guizhou Hospital,Beijing Jishuitan Hospital from February 2020 to February 2023 were selected for scoliosis orthopedics.During the operation,the 5-point positioning point-contact pedicle navigation template was used to guide the screws.According to the inclusion and exclusion criteria,34 cases were matched as the empirical nail placement group,and conventional barehanded nail placement was performed.The time of placement,the amount of bleeding,the number of fluoroscopies,the number of manual diversions,the level and accuracy of pedicle screws,the complications of placement,and the rate of correction of main curvature were compared between the two groups. RESULTS AND CONCLUSION:(1)There were no significant differences in sex,age,coronal Cobb's angle of the main curvature,bending Cobb's angle of the main curvature,pedicle variation,apex rotation,fusion segment,number of screws,level of screws,accuracy of screws,and rate of correction of main curvature between the navigation template group and the empirical nail placement group(P>0.05).(2)Compared with the empirical nail placement group,the navigation template group had more advantages in time of placement(P=0.034),amount of bleeding(P=0.036),number of fluoroscopies(P=0.000)and number of manual diversions(P=0.021).(3)There were 0 cases of screw-related complications in both groups.(4)In conclusion,the 5-point positioning point-contact 3D printing pedicle navigation template has a claw-like structure.It can firmly adapt to various deformities of the lamina articular process,avoid drift,and accurately place the screws.It has a point-like contact lamina structure to avoid extensive and complete dissection of the posterior structure,and reduce bleeding,operation time,and trauma.Pre-designed screw entry points and directions can reduce the number of fluoroscopy and operation time.Segmental design can avoid discomfort due to changes in anesthesia position.The operation is simple and the accuracy of screw placement is high.

Objective To explore the mechanism of action of lamotrigine in the treatment of major depressive disorder(MDD).Methods Information on the drug targets of lamotrigine and the therapeutic targets of MDD were collected for intersection target gene analysis and protein-protein interaction screening.Various biological pathways related to lamotrigine in treatment of MDD were determined through gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis.The screened core targets were preliminarily validated using molecular docking technology.Further validation of Mendelian randomization was conducted using genome-wide association analysis data from gamma-aminobutyric acid recep tor-associated protein-like 1(GABARAPL1)and MDD in the OpenGWAS database.Results The biological pathways related to lamotrigine in treatment of MDD were identified,which included gamma-aminobutyric acid(GABA)ergic synapses,nicotine addiction,glutamatergic synapses,endogenous cannabinoid signaling.Molecular docking showed that the docking energy of lamotrigine with GABRA1,GABRB2,GABRA6,GABRD,GABRG2,GABRG1,GABRA5,GABRA4,GABRB3,and GABRA2 receptors was-5.8 kCal·mol-1.Among them,the GABRB3 receptor showed the strongest docking energy with lamotrigine,which was-9.5 kCal·mol-1.In the genome-wide association analysis data of GABARAPL1,303 single nucleotide polymorphisms were associated with GABARAPL1(P＜5 × 106).15 single nucleotide polymorphisms were screened and retained for Mendelian randomization analysis,and the results showed that GABA receptors may be an important therapeutic target for MDD.Conclusion The treatment of MDD with lamotrigine may be achieved by acting on GABA receptors,which provided a research basis for the clinical application of lamotrigine in treating MDD.

Objective To formulate the quantitative grip strength training program for application in the postoperative patients with autogenous arteriovenous internal fistula,and to evaluate its effect on the mat-uration and initial use of autogenous arteriovenous internal fistula.Methods A total of 98 patients with ce-phalic venous radial arterial anastomosis internal fistula formation surgery in Shenzhen Hospital of Southern Medical University from September 2021 to November 2022 were selected as the study subjects by the conven-ience sampling method.According to the follow-up time,they were divided into the observation group (n=41) and control group (n=42).The observation group adopted the quantitative grip strength training for function-al exercise of the limb on the side of internal fistula,while the control group adopted the conventional grip training for functional exercise of the limb on the side of internal fistula.In postoperative 8 weeks,the matura-tion rate of internal fistula,natural blood flow amount of internal fistula,internal diameter of cephalic vein,pre-pump pressure used in the initial stage of internal fistula and the incidence rate of internal fistula complica-tions were evaluated in the two groups.Results Compared with the control group,the maturation rate of in-ternal fistula in the observation group was higher (97.6％ vs. 83.3％).The inner diameter of cephalic vein and natural blood flow amount of internal fistula in the observation group were larger than those in the control group[(5.24±0.66)mm vs. (4.63±0.59)mm;(1215.38±562.99)mL/min vs. (955.75±341.94)mL/min],the pre-pump pressure used at the initial stage of internal fistula in the observation group was lower than that in the control group[(119.20±19.83)mmHg vs. (135.74±17.07)mmHg],and the differences were statistically significant (P<0.05).Conclusion The quantitative grip strength training could increase the postoperative maturity rate of patients's internal fistula,and is beneficial to the use in the initial stage of internal fistula.

OBJECTIVE To observe the clinical efficacy and effect on serum thymic stromal lymphopoietin(TSLP)levels of pa-tients with advanced liver cancer of qi deficiency and toxic stasis type by Jiawei Yupingfeng San.METHODS Using random double blind method,120 patients with advanced liver cancer of qi deficiency and toxic stasis type were randomly divided into 3 groups:Jiawei Yupingfeng San group,Yupingfeng San group,and placebo group,each consisting of 40 cases.All patients in the 3 groups were given conventional treatment such as radiotherapy,chemotherapy,interventional or targeted therapy;Jiawei Yupingfeng San group was given Jiawei Yupingfeng San granules,Yupingfeng San group was given Yupingfeng San granules,and placebo group was given placebo.The course of treatment was 2 months.The changes of Karnofsky functional status score(KPS score),TCM syndrome score,tumor size and serum TSLP level in the 3 groups were observed before and after treatment,and the correlation between the changes of tumor size and TSLP was analyzed.RESULTS After treatment,the KPS scores of Yupingfeng San group and Jiawei Yupingfeng San group were sig-nificantly increased(P<0.05,P<0.01),TCM syndrome score were decreased(P<0.01),tumor growth(P<0.05,P<0.01)was de-layed,and serum TSLP levels(P<0.05,P<0.01)were decreased.Furthermore,there was a slight positive correlation between chan-ges in tumor size and changes in TSLP(P<0.05).In terms of improving tumor size,the curative effect of Jiawei Yupingfeng San group was better than that of Yupingfeng San group(P<0.05).During the treatment period,no obvious adverse reactions were observed in the 3 groups of patients.CONCLUSION Combined with conventional treatment,Jiawei Yupingfeng San can significantly delay tumor growth in patients with advanced liver cancer of qi deficiency and toxic stasis type and improve patients'TCM syndromes and their qual-ity of survival.The therapeutic mechanism is related to reducing the expression of serum TSLP and improving the immune status of pa-tients,thereby delaying the growth of tumors.

Objective:Non-alcoholic fatty liver disease(NAFLD)is a common metabolic disorder in overweight and obese children,and its etiology and pathogenesis remain unclear,lacking effective preventive and therapeutic measures.This study aims to explore the association between whole blood copper,zinc,calcium,magnesium and iron levels and NAFLD in overweight and obese children aged 6 to 17 years,providing a scientific basis for the prevention and intervention of early NAFLD in overweight and obese children. Methods:A cross-sectional study design was used to collect relevant data from overweight and obese children who visited the Hunan Children's Hospital from January 2019 to December 2021 through questionnaire surveys.Fasting blood samples were collected from the subjects,and various indicators such as blood glucose,blood lipid,and mineral elements were detected.All children were divided into an overweight group(n=400)and a NAFLD group(n=202).The NAFLD group was divided into 2 subgroups according to the ALT level:A non-alcoholic fatty liver(NAFL)group and a non-alcoholic steatohepatitis(NASH)group.Logistic regression analysis was used to analyze the association between minerals(copper,zinc,calcium,magnesium,and iron)and NAFLD,NAFL and NASH. Results:A total of 602 subjects were included,of whom 73.6%were male,with a median age of 10(9,11)years,and a body mass index(BMI)of 24.9(22.7,27.4)kg/m2.The intergroup comparison results showed that compared with the overweight group,the NAFLD group had higher levels of age,BMI,diastolic blood pressure(DBP),systolic blood pressure(SBP),triglyceride(TG),low density lipoprotein(LDL),alanine transaminase(ALT)and aspartate aminotransferase(AST),and lower level of high density lipoprotein(HDL).The NAFL group had higher levels of age,BMI,DBP,SBP,ALT,and AST,and lower levels of HDL compared with the overweight group.The levels of age,BMI,DBP,SBP,TG,LDL,ALT,and AST of NASH were higher than those in the overweight group,while the level of HDL was lower than that in overweight group(all P<0.017).After adjusting for a variety of confounders,the OR of NAFLD for the highest quantile of iron was 1.79(95%CI 1.07 to 3.00)compared to the lowest quantile,and no significant association was observed between copper,zinc,calcium,and magnesium,and NAFLD.The subgroup analysis of NAFLD showed that the OR for the highest quantile of iron in children with NAFL was 2.21(95%CI 1.26 to 3.88),while no significant association was observed between iron level and NASH.In addition,no significant associations were observed between copper,zinc,calcium,and magnesium levels and NAFL or NASH. Conclusion:High iron level increases the risk of NAFLD(more likely NAFL)in overweight and obese children,while copper,zinc,calcium,magnesium,and other elements are not associated with the risk of NAFLD in overweight and obese children.

Objective To study the distribution and significance of CD1a and CD83 positive dendritic cells(DCs)in lung tissue of chronic obstructive pulmonary disease(COPD)mice.Methods Twenty C57BL/6 mice were randomly divided into the air control group and the smoked COPD group(n=10 for each group).COPD mouse model was established using cigarette smoking method.Mice were executed within 24 h after the last cigarette smoking,and right lower lung was collected.Body mass changes and lung histopathological changes of mice were observed in two groups.Mean linear intercept(MLI)was measured,and expression levels of CD1a+and CD83+DCs in lung tissue were detected by immunohistochemistry.Results The body mass of mice at 7,14,21 and 28 d after modeling was lower in the smoked COPD group than that in the air control group(P＜0.05).HE staining showed that the normal alveolar structure of lung tissue of mice in the smoked group was disrupted,with multiple alveoli fused with each other to form a larger alveolar lumen,a large number of inflammatory cells infiltrated in alveolar intervals,and walls of the alveoli were thickened.COPD modeling was successful.Compared with the air control group,MLI values(μm)increased in the smoked COPD group(28.30±3.47 vs.50.40±3.60),and the number of CD1a+DCs(per field of view)in lung tissue increased(9.58±2.18 vs.17.08±3.67),while the number of CD83+DCs(per field of view)decreased(19.78±4.95 vs.8.02±3.30)(all P＜0.05).Conclusion The number of CD1a+DCs in lung tissue is increased and the number of CD83+DCs in lung tissue is decreased in the smoked COPD group of mice,and cigarette smoking may have impaired DC maturation.
