1.Theoretical research on LOU Ying′s guideline and item syndrome differentiation
Journal of Beijing University of Traditional Chinese Medicine 2025;48(4):483-489
The guideline and item classification approach represents a distinct historical method ology, first introduced by ZHU Xi in his Compendium of Comprehensive Mirror for Aid in Government during the Southern Song Dynasty. LOU Ying later adapted this framework to the field of traditional Chinese medicine, critically analyzing and addressing the limitations of prior academic theories. By drawing upon the rich intellectual traditions of classical texts and historical works, LOU Ying restructured and refined his ideas, ultimately establishing the "guideline and item" medical theory. This innovative framework profoundly influenced LOU Ying′s work, shaping both the compilation of medical texts and the development of novel theoretical approaches in traditional Chinese medicine. In disease differentiation and treatment, LOU Ying proposed the theory of guideline and item classification, that is, taking yin and yang as two guidelines, taking qi and blood, exterior and interior, upper and lower parts, deficiency and excess, cold and heat as ten items, and constructing a syndrome differentiation system focusing on qi and blood, focusing solely on upper and lower parts, distinguishing exterior and interior, carefully examining deficiency and excess, and distinguishing cold and heat. The guideline and item classification system integrates and harmonizes multiple syndrome differentiation method ologies, including the eight-principle pattern identification, viscera syndrome differentiation, differentiation of syndromes according to the pathogenesis of Sanjiao, and qi-blood-fluid pattern identification. As a precursor to modern method of syndrome differentiation and treatment, it possesses unique theoretical significance and considerable clinical relevance. Its applicability to diagnosing and treating various diseases, coupled with its greater operational practicality compared to other methods, highlights its value in contemporary clinical practice. This system offers a complementary and enhanced framework for syndrome differentiation and treatment, warranting further adoption and promotion in the clinical setting.

BACKGROUND:
The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China.
METHODS:
This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences.
RESULTS:
Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n = 278] vs . 43.7% [ n = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses.
CONCLUSION
This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

ObjectiveTo explore the effect of Buzhong Yiqitang on the immune imbalance of helper T cell 17 (Th17)/regulatory T cell (Treg) and Notch1 signaling pathway in mice with autoimmune thyroiditis (AIT). MethodA total of 60 8-week-old NOD.H-2h4 mice were randomly divided into the normal group, model group, western medicine group (selenium yeast tablet, 32.5 mg·kg-1), and low-dose (4.78 g·kg-1·d-1), middle-dose (9.56 g·kg-1·d-1), and high-dose (19 g·kg-1·d-1) Buzhong Yiqitang groups, with 10 mice in each group. The normal group was fed with distilled water, and the other groups were fed with water containing 0.05% sodium iodide for eight weeks. After the animal model of AIT was formed spontaneously, the mice were killed under anesthesia after intragastric administration for eight weeks. Serum anti-thyroglobulin antibodies (TGAb), thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroid hormone (FT4) were detected by enzyme-linked immunosorbent assay (ELISA), and thyroid tissue changes were observed by hematoxylin-eosin (HE) staining. The mRNA and protein expressions of retinoid-related orphan receptor-γt (RORγt), interleukin (IL)-17, forkhead box P3 (FoxP3), IL-10, Notch1, and hair division-related enhancer 1 (Hes1) in thyroid tissue were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultCompared with the normal group, the thyroid structure of the model group was severely damaged, and lymphocytes were infiltrated obviously. The levels of serum TGAb, FT3, and FT4 contents were significantly increased, and TSH content was significantly decreased (P<0.01). The mRNA and protein expression levels of RORγt, IL-17, Notch1, and Hes1 were significantly increased, while those of FoxP3 and IL10 were significantly decreased in the model group (P<0.01). Compared with the model group, thyroid structural damage and lymphocyte infiltration were improved in the treatment groups, and serum TGAb, FT3, and FT4 contents were significantly decreased. TSH content was increased, and mRNA and protein expression levels of RORγt, IL-17, Notch1, and Hes1 were decreased. mRNA and protein expression levels of FoxP3 and IL-10 were increased to different degrees (P<0.05, P<0.01), and the middle-dose Buzhong Yiqitang group had the most significant intervention effect. ConclusionBuzhong Yiqitang can alleviate the thyroid structural damage in AIT mice, and its mechanism may be related to improving the abnormal differentiation of Th17/Treg immune cells and inhibiting the activation of the Notch1 signaling pathway.

Objective:To investigate the association between body composition and coronary artery calcification in patients with chronic kidney disease (CKD).Methods:This cross-sectional study enrolled patients with CKD hospitalized from May 2019 to April 2022 at Sun Yat-sen Memorial Hospital, Guangzhou, China. Skeletal muscle mass index and visceral fat area were measured by bioelectrical impedance analysis. Coronary artery calcification was assessed by computed tomography. Patients were divided into coronary artery calcification group and non-coronary artery calcification group according to the incidence of coronary artery calcification. Patients were categorized into tertile groups according to their skeletal muscle mass index and visceral fat area levels ranging from the lowest to the highest levels (T1 to T3). We defined skeletal muscle mass index≤30.4% as low muscle mass and visceral fat area≥80.6 cm 2 as high visceral fat based on the results of the restricted cubic spline graph. All individuals were divided into 4 phenotypes: normal body composition, low muscle mass, high visceral fat, and low muscle mass with high visceral fat. Spearman correlation analysis and logistic regression analysis were used to assess the association between skeletal muscle mass index, visceral fat area and coronary artery calcification. Results:A total of 107 patients with CKD were enrolled, with an age of (60.0±14.1) years, including 41 female patients (38.3%). Patients of coronary artery calcification group had lower skeletal muscle mass index ((32.0±4.8) vs. (34.3±4.8), P=0.016) and higher visceral fat area ((70.8±32.6) cm 2 vs. (47.9±23.8) cm 2, P<0.001) than those of non-coronary artery calcification group. Patients in the T3 group of skeletal muscle mass index had a lower prevalence of coronary artery calcification (17 (48.6%) vs. 28 (77.8%)) and a lower coronary artery calcification score (0.5 (0, 124.0) vs. 12.0 (0.3, 131.0)) than those in the T1 group ( P<0.05). Similarly, patients in the T1 group of visceral fat area had a lower prevalence of coronary artery calcification (14 (40.0%) vs. 29 (80.6%)) and a lower coronary artery calcification score (0 (0, 3.0) vs. 37.0 (2.0, 131.0)) than those in the T3 group ( P<0.05). Likewise, patients with both low muscle mass and low muscle mass with high visceral fat had a higher prevalence of coronary artery calcification (11(78.6%) vs. 33 (47.8%); 15 (83.3%) vs. 33 (47.8%)) and a higher coronary artery calcification score (31.1 (0.8, 175.8) vs. 0 (0, 16.4); 27.6 (6.4, 211.4) vs. 0 (0, 16.4)) than those with normal body composition ( P<0.05). Spearman correlation analysis showed that skeletal muscle mass index was inversely correlated with coronary artery calcification score ( r=-0.212, P=0.028), and visceral fat area was positively correlated with coronary artery calcification score ( r=0.408, P<0.001). Multivariate logistic regression analysis showed that increased skeletal muscle mass index was inversely associated with coronary artery calcification prevalence (T2: OR=0.208, 95% CI: 0.056-0.770, P=0.019; T3: OR=0.195, 95% CI: 0.043-0.887, P=0.034), and reduced visceral fat area was inversely associated with coronary artery calcification prevalence (T1: OR=0.256, 95% CI: 0.071-0.923, P=0.037; T2: OR=0.263, 95% CI: 0.078-0.888, P=0.031). Consistently, both low muscle mass and low muscle mass with high visceral fat were associated with coronary artery calcification prevalence ( OR=6.616, 95% CI: 1.383-31.656, P=0.018; OR=5.548, 95% CI: 1.062-28.973, P=0.042). Conclusion:Reduced skeletal muscle mass index and increased visceral fat area are significantly associated with both the prevalence and severity of coronary artery calcification in patients with CKD.

Although significant progress has been made in the development of novel targeted drugs for the treatment of acute myeloid leukemia(AML)in recent years,chemotherapy still remains the mainstay of treatment and the overall survival is poor in most patients.Here,we demonstrated the antileukemia activity of a novel small molecular compound NL101,which is formed through the modification on bendamustine with a suberanilohydroxamic acid(SAHA)radical.NL101 suppresses the proliferation of myeloid malignancy cells and primary AML cells.It induces DNA damage and caspase 3-mediated apoptosis.A genome-wide clustered regularly interspaced short palindromic repeats(CRISPR)library screen revealed that phosphatase and tensin homologous(PTEN)gene is critical for the regulation of cell survival upon NL101 treatment.The knockout or inhibition of PTEN significantly reduced NL101-induced apoptosis in AML and myelodysplastic syndrome(MDS)cells,accompanied by the activation of protein kinase B(AKT)signaling pathway.The inhibition of mammalian target of rapamycin(mTOR)by rapamycin enhanced the sensitivity of AML cells to NL101-induced cell death.These findings uncover PTEN protein expression as a major determinant of chemosensitivity to NL101 and provide a novel strategy to treat AML with the combination of NL101 and rapamycin.

ObjectiveTo explore the mechanism of Buzhong Yiqitang in ameliorating inflammatory injury in autoimmune thyroiditis (AIT) mice based on the Toll-like receptor 4(TLR4)/nuclear transcription factor-kappa B(NF-κB)/absent in melanoma 2(AIM2)inflammasome signaling pathway. MethodThe 120 genetically susceptible 8-week-old NOD.H-2h4 mice were selected and randomly divided into control group, model group, low, medium and high dose groups of Buzhong Yiqitang (4.78, 9.56, 19.12 g·kg-1), and western medicine group (selenium yeast tablets, 3.033×10-5 g·kg-1). The AIT model mice in each group drank ad libitum 0.05% sodium iodide aqueous solution for 8 weeks to establish the AIT model, and the control group drank ad libitum distilled water. Eight weeks later, the mice in each dosing group were divided into groups and gavage. The swelling of thyroid tissue was observed with the naked eye, and the weight of spleen was weighed. The content of serum inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) was measured by enzyme-linked immunosorbent assay (ELISA), and Real-time PCR was used to detect the expression of HMGB1, TLR4, AIM2, NF-κB p65,apoptosis-associated speck-like protein(ASC),cysteinyl aspartate-specific protease-1(Caspase-1), IL-1β mRNA. Western blot was used to detect the expression of high motility group protein 1 (HMGB1), TLR4, AIM2, NF-κB p65, phosphorylation(p)-NF-κB p65, ASC, Caspase-1, and IL-1β proteins in thyroid tissue, and immunofluorescence staining was used to observe the protein expression of HMGB1, AIM2, and NF-κB p65 in thyroid tissue of mice. ResultCompared with the control group, the thyroid tissue of mice in the model group was significantly swollen, the spleen quality was significantly increased, and the expression of HMGB1, TLR4, NF-κB p65, AIM2, ASC, Caspase-1, IL-1β in thyroid tissue was significantly increased (P<0.01). Compared with the model group, the swelling of thyroid tissue in mice in each dose group of Buzhong Yiqitang was improved, the quality of spleen was significantly reduced, and the expression of HMGB1, TLR4, AIM2, NF-κB p65, p-NF-κB p65, ASC, Caspase-1, IL-1β in thyroid tissue was significantly reduced (P<0.05, P<0.01). ConclusionBuzhong Yiqitang can effectively improve the inflammatory injury of AIT, and regulating the abnormal activation of the TLR4/NF-κB/AIM2 inflammasome signal pathway may be one of its intervention mechanisms.

ObjectiveTo investigate the mechanism of Buzhong Yiqitang in ameliorating ferroptosis in autoimmune thyroiditis (AIT) mice based on the nuclear factor erythroid 2-related factor 2 (Nrf2)/peroxisome proliferator-activated receptor γ (PPARγ)/glutathione peroxidase 4 (GPX4) pathway. Method120 SPF-grade 7-8-week-old NOD.H-2h4 mice were randomly divided into control group, model group, low-, medium-, and high-dose Buzhong Yiqitang groups, and western medicine group, with 20 mice in each group. Except for the control group, all mice were fed with classic high-iodine water (0.05% NaI) to induce AIT models after 8 weeks. The low-, medium-, and high-dose Buzhong Yiqitang groups were administered 4.78, 9.56, 19.12 g·kg-1 of Buzhong Yiqitang, respectively, via gavage. The western medicine group was given 3.033×10-5 g·kg-1 selenium yeast tablet suspension via gavage, while the control and model groups were given an equal volume of distilled water via gavage. After 8 weeks of continuous treatment, samples were collected. The pathological morphology of mouse thyroid tissue was observed through hematoxylin-eosin (HE) staining,the content of serumantithyroid peroxidase autoantibody(TPOAb)and anti-thyroglobulin antibodies(TGAb)was measured by enzyme-linked immunosorbent assay (ELISA),the kit was used to detect the levels of superoxide dismutase (SOD), and malondialdehyde (MDA) in mouse serum.

ObjectiveTo investigate the effects of Buzhong Yiqitang on the tumor necrosis factor receptor superfamily member 6 (Fas)/Fas related death domain protein (FADD)/Caspase-8 cell apoptotic signaling pathway in mice model with autoimmune thyroiditis (AIT). MethodThere were 120 SPF grade NOD.H-2h4 mice aged 8 weeks, 100 of which were fed with high iodine water (0.05% NaI), and the AIT model was made after 8 weeks. According to random number table method, they were divided into model group, Buzhong Yiqitang low-dose, medium-dose and high-dose groups (4.78, 9.56, 19.12 g·kg-1), selenium yeast tablet group (3.033×10-5 g·kg-1), with 20 mice in each group and 20 control group. The apoptosis of thyroid cells was detected by in situ end labeling (TUNEL) after 8 weeks of administration. The real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of Fas, FADD, Caspase-8, and Caspase-3 in thyroid tissue. Western blot was used to detect the protein expression of Fas, FADD, Caspase-8, Caspase-3, cleaved Caspase-8, and cleaved Caspase-3 in thyroid tissue, and the immunohistochemical method was used to detect the protein expression of Fas and Caspase-3 in thyroid tissue. ResultCompared with control group, there were more positive expressions of apoptotic cells in model group under fluorescence microscope, and the expressions of Fas, FADD, Caspase-8, Caspase-3, cleaved Caspase-8 and cleaved Caspase-3 were significantly increased (P<0.05, P<0.01). Compared with model group, the positive expression of thyroid apoptotic cells in each administration group was decreased under fluorescence microscope, and the expressions of Fas, FADD, Caspase-8, Caspase-3, cleaved Caspase-8, cleaved Caspase-3 were significantly decreased (P<0.05, P<0.01). ConclusionBuzhong Yiqitang can effectively improve thyroid cell apoptosis and inflammatory injury in AIT mice. The mechanism may be related to the inhibition of Fas/FADD/Caspase-8 signaling pathway.
