"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 further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

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.

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 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 study the pharmacokinetic characteristics of lamotrigine tablets in Chinese healthy subjects under fasting and fed conditions,and to evaluate the bioequivalence and safety profiles between the domestic test preparation and the original reference preparation.Methods Twenty-four Chinese healthy male and female subjects were enrolled under fasting and fed conditions,18 male and 6 female subjects under fasting conditions,17 male and 7 female subjects under fed conditions.A random,open,single-dose,two preparations,two sequences and double-crossover design was used.Plasma samples were collected over a 72-hour period after give the test or reference preparations 50 mg under fasting and fed conditions.The concentration of lamotrigine in plasma was detected by liquid chromatography-tandem mass spectrometry,and the main pharmacokinetic parameters were calculated to evaluate the bioequivalence by WinNonLin 8.1 program.Results The main pharmacokinetic parameters of single-dose the tested and reference preparations were as follows:The fasting condition Cmax were(910.93±248.02)and(855.87±214.36)ng·mL-1;tmax were 0.50(0.25,4.00)and 1.00(0.25,3.50)h;t1/2 were(36.1±9.2)and(36.0±8.2)h;AUC0_72h were(27 402.40±4 752.00)and(26 933.90±4 085.80)h·ng·mL-1.The fed condition Cmax were(701.62±120.67)and(718.95±94.81)ng·mL-1;tmax were 4.00(1.00,5.00)and 4.00(0.50,5.00)h;t1/2 were(44.2±12.4)and(44.0±12.0)h;AUC0-72h were(30 253.20±7 018.00)and(30 324.60±6 147.70)h·ng·mL-1.The 90％confidence intervals of the geometric mean ratios of Cmax and AUC0-72 hfor the test preparation and reference preparation were all between 80.00％and 125.00％under fasting and fed conditions.Conclusion Two kinds of lamotrigine tablets are bioequivalent,and have similar safety in Chinese healthy male and female subjects under fasting and fed conditions.

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.
