BACKGROUND:Epidemiological studies indicate that individuals with neurodegenerative diseases exhibit a comparatively lower risk of developing the majority of cancers.Although the precise mechanisms underlying this inverse correlation remain unclear,it is noteworthy that aberrant glucose metabolism,a pathological factor common to both conditions,may significantly contribute to this association.OBJECTIVE:To review the potential relationship between cancers and neurodegenerative diseases in glucose metabolism.METHODS:PubMed was searched for relevant literature using the search terms of"cancer,neurodegenerative diseases,Alzheimer's disease,Parkinson's disease,metabolic reprogramming,glucose metabolism,aerobic glycolysis,neuroprotection,aging,"and 136 articles were finally included for analysis.RESULTS AND CONCLUSION:Cancer and neurodegenerative diseases exhibit a profound pathological correlation at the level of glucose metabolism imbalance associated with aging.Cancer cells promote uncontrolled proliferation,invasion,and metastasis through the persistent activation of aerobic glycolysis,whereas neurodegenerative diseases are characterized by a reduction in aerobic glycolysis.Restoring aerobic glycolysis may confer neuroprotective effects and delay disease progression.The key nodes of glucose metabolism demonstrate a bidirectional regulatory pattern:metabolic regulators,which are significantly upregulated or aberrantly activated in cancer,are inhibited or functionally inactivated in neurodegenerative diseases.Mitochondria play a crucial role in mediating the aging process through the regulation of reactive oxygen species homeostasis and mitochondrial autophagy.They establish regulatory networks that connect cancer and neurodegenerative diseases,and maintaining their functional homeostasis is of paramount importance for disease prevention and treatment.

ObjectiveTo investigate the effects of Yueju Wan on the 5-hydroxytryptamine (5-HT) signaling pathway in rats with functional dyspepsia (FD) and to explore its therapeutic mechanism in the treatment of FD. MethodsSixty Sprague-Dawley (SD) rats were randomly divided into a normal group, model group, mosapride group (1.575 mg·kg-1), and Yueju Wan low-, medium-, and high-dose groups (0.735, 1.47, and 2.94 g·kg-1, respectively). The FD rat model was established using GUO's tail-clamping stimulation combined with irregular feeding. After 14 days of modeling, rats were administered the corresponding drugs by gavage for 28 days. After treatment, gastric emptying rate and small intestinal propulsion rate were measured. Serum levels of 5-HT, tryptophan hydroxylase (TPH), and substance P (SP) were detected by enzyme-linked immunosorbent assay (ELISA), and acetylcholine (ACh) levels were determined by chemical methods. Histopathological changes in the gastric antrum were observed using hematoxylin-eosin (HE) staining. Real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot were used to assess the mRNA and protein expression levels of 5-hydroxytryptamine 4 receptor (5-HT4R), SP, and acetylcholinesterase (AChE) in colon tissue, as well as 5-hydroxytryptamine 3 receptor (5-HT3R), SP, and AChE in hypothalamic tissue. Immunohistochemistry (IHC) was used to examine the expression of 5-HT and 5-HT4R in the colon and 5-HT and 5-HT3R in the hypothalamus. ResultsCompared with the normal group, the gastric emptying rate and small intestinal propulsion rate in the model group were significantly decreased (P<0.01). Serum levels of 5-HT, SP, ACh, and TPH were significantly reduced (P<0.01). Histopathological examination revealed irregular arrangement of glands in the gastric antrum, slight mucosal atrophy, and mild inflammatory cell infiltration. The mRNA and protein expression levels of 5-HT4R, SP, and AChE in colon tissue, as well as 5-HT3R, SP, and AChE in hypothalamic tissue, were significantly decreased (P<0.01), and 5-HT protein expression in both the colon and hypothalamus was also significantly reduced (P<0.01). Compared with the model group, all Yueju Wan groups showed significantly increased gastric emptying rate and small intestinal propulsion rate (P<0.01). The glands in the gastric antrum were more regularly arranged, with no inflammatory cell infiltration observed. Serum levels of 5-HT, SP, ACh, and TPH were significantly increased (P<0.01). The mRNA and protein expression levels of 5-HT4R, SP, and AChE in colon tissue and 5-HT3R, SP, and AChE in hypothalamic tissue were significantly upregulated (P<0.05, P<0.01), and 5-HT protein expression in both the colon and hypothalamus was significantly increased (P<0.01). ConclusionYueju Wan has preventive and therapeutic effects on FD, and its mechanism may be related to regulation of the 5-HT signaling pathway, promotion of brain-gut peptide secretion, and enhancement of gastric motility.

Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage (Shang Han Lun). This prescription is composed of Bupleuri Radix, Scutellariae Radix, Cinnamomi Ramulus, Zingiberis Rhizoma, Trichosanthis Radix, Ostreae Concha, and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang, warming the spleen, and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis (CC), irritable bowel syndrome, and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain, poor appetite, postprandial fullness, aversion to greasy food, soft stool, and bitter mouth, being a type of biliary dyspepsia. In modern medicine, dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation, promoting the function of gallbladder, resolving stones, alleviating spasms, and relieving the pain for CC, demonstrating definite short-term efficacy but suffering from single effects, high recurrence rate, and poor compliance. Although surgical treatment can cure cholecystitis, it is accompanied by the increased incidence of adverse events such as abdominal pain, diarrhea, and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins, baicalin, cinnamaldehyde, gingerol, Trichosanthis Radix polysaccharide, Ostreae Concha polysaccharide, and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses, improving gallbladder contraction and gastrointestinal motility, regulating the bile acid-intestinal flora axis and the brain-gut axis, and modulating blood lipids through multiple targets. By reviewing the previous literature, this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

ObjectiveTo evaluate the effects and safety of the optimized new Shengmai Powder (优化新生脉散方) on exercise tolerance in patients with chronic heart failure (CHF) of qi deficiency, blood stasis, and fluid retention syndrome. MethodsA randomized, double-blind, placebo-controlled trial was conducted. A total of 78 CHF patients with qi deficiency, blood stasis, and fluid retention syndrome were recruited and randomly assigned to a treatment group (39 cases) and a control group (39 cases). On the basis of conventional western medical therapy, patients in the treatment group additionally received the optimized new Shengmai Powder granules, while the control group was given an oral placebo of optimized new Shengmai Powder granules. Patients in both groups took 30.6 g each time, twice a day, mixed with water for administration, with a total treatment course of 4 weeks. The primary outcomes were 6-minute walk distance (6MWD) and peak oxygen uptake (Peak VO2) measured by cardiopulmonary exercise testing. Secondary outcomes included New York Heart Association (NYHA) functional classification, B-type natriuretic peptide (BNP) levels, cardiac function indexes including left ventricular ejection fraction (LVEF), left ventri-cular end-systolic diameter (LVESD) and left ventricular end-diastolic diameter (LVEDD), Minnesota Living with Heart Failure Questionnaire (MLHFQ) scores, and scores of four diagnostic information of traditional Chinese medicine (TCM). All indicators were assessed once before and after treatment respectively. Safety indicators were evaluated, and adverse events during the trial were recorded. ResultsAll patients in both groups were included in the full ana-lysis set (FAS) and safety set (SS). Compared with baseline, the 6MWD and Peak VO₂ of cardiopulmonary exercise test in the treatment group significantly increased after treatment, while the MLHFQ scores, serum BNP levels and scores of TCM four diagnostic information significantly decreased, and the NYHA cardiac function grade significantly improved (P<0.01). After treatment, the 6MWD and Peak VO₂ of cardiopulmonary exercise test, as well as their changes from baseline in the treatment group were higher than those in the control group; the MLHFQ scores, serum BNP levels and scores of TCM four diagnostic information in the treatment group were lower than those in the control group; and the improvement of NYHA cardiac function grade in the treatment group was superior to that in the control group (P<0.01). There was no statistically significant differences in all indicators after treatment in the control group (P>0.05). The incidence of adverse events was 5.1% (2/39) in the treatment group and 2.6% (1/39) in the control group, with no statistically significant difference between groups (P>0.05). ConclusionOn the basis of conventional western medicine treatment, the addition of the optimized new Shengmai Powder can further improve exercise tolerance, cardiac function and quality of life in patients with CHF of qi deficiency, blood stasis and fluid retention syndrome, and show good safety.

AIM: To investigate the diagnostic and prognostic value of differential expression of Cyclin D1 and p53 in eyelid tumors.METHODS: This retrospective study enrolled patients who underwent surgical resection for eyelid tumors at our hospital between March 2018 and March 2023. Participants were categorized into benign and malignant groups based on tumor characteristics. Clinical data were collected. Genetic data for eyelid tumors were obtained from the GEO database, and differential gene analysis, including volcano plot visualization and KEGG pathway enrichment analysis, was performed using the Sangerbox 3.0 platform. Immunohistochemistry was used to detect the expression levels of Cyclin D1, p53, and BAX in tissue samples. Correlations with clinical features were analyzed using Spearman analysis, and prognostic factors were identified via Logistic regression analysis.RESULTS: This study included 69 patients with eyelid tumors(78 eyes), categorized into a benign group(37 patients, 41 eyes)and a malignant group(32 patients, 37 eyes)based on tumor characteristics. There were significant differences between the two groups in histological subtype, TNM staging, vascular invasion, differentiation status, and local infiltration(all P<0.05). Among benign tumors: pigmented nevi in 11 eyes(27%), hemangiomas in 9 eyes(22%), squamous cell papillomas in 5 eyes(12%), epidermoid cysts in 5 eyes(12%), seborrheic keratoses in 4 eyes(10%), neurofibromas in 3 eyes(7%), and both calcifying epithelioma and xanthelasma in 2 eyes each(5%); among malignant tumors: basal cell carcinoma in 18 eyes(49%), meibomian gland carcinoma in 8 eyes(22%), squamous cell carcinoma in 5 eyes(14%), sebaceous gland carcinoma in 4 eyes(11%), lymphoma and malignant melanoma each in 1 eye(3%). At the follow-up cutoff date of March 2025, the 2-year survival rate in the benign group(95%)was significantly higher than that in the malignant group(78%; P<0.05). Bioinformatics analysis identified 4 103 differentially expressed genes, including Cyclin D1, p53, and BAX, which were predominantly involved in pathways such as the p53 signaling pathway and calcium-related signaling. Spearman analysis revealed that local invasion(rs=0.71, P<0.05)and TNM stage(rs=0.73, P<0.05)correlated with Cyclin D1 expression; local invasion(rs=0.76, P<0.05)and histological subtype(rs=0.65, P<0.05)correlated with p53 expression. Logistic regression results indicated that Cyclin D1, p53, TNM staging, and local invasion were prognostic risk factors. ROC curve analysis demonstrated that the combined detection of these four indicators had the highest predictive value for prognosis(AUC=0.83).CONCLUSION: High expression of cyclin D1 and p53 serves as molecular markers for distinguishing benign from malignant eyelid tumors and assessing prognosis. Combined detection of these markers with TNM staging and local invasion demonstrates high predictive value for prognosis.

Objective:
To analyze the epidemiological characteristics and influencing factors of severe fever with thrombocytopenia syndrome (SFTS) in Zhejiang Province from 2019 to 2023, so as to provide the reference for strengthening SFTS prevention and control.
Methods:
Data on laboratory-confirmed SFTS cases in Zhejiang Province from 2019 to 2023 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Meteorological data, geographic environment and socioeconomic factors during the same period were collected from the fifth-generation European Centre for Medium-Range Weather Forecasts, Geospatial Data Cloud, and Zhejiang Statistical Yearbook, respectively. Descriptive epidemiological methods were used to analyze the epidemiological characteristics of SFTS from 2019 to 2023, and a Bayesian spatio-temporal model was constructed to analyze the influencing factors of SFTS incidence.
Results:
A total of 578 SFTS cases were reported in Zhejiang Province from 2019 to 2023, with an annual average incidence of 0.23/105. The peak period was from May to July, accounting for 52.60%. There were 309 males and 269 females, with a male-to-female ratio of 1.15∶1. The cases were mainly aged 50-<80 years, farmers, and in rural areas, accounting for 82.53%, 77.34%, and 75.43%, respectively. Taizhou City and Shaoxing City reported more SFTS cases, while Shaoxing City and Zhoushan City had higher annual average incidences of SFTS. The Bayesian spatio-temporal interaction model showed good goodness of fit. The results showed that mean temperature (RR=1.626, 95%CI: 1.111-2.378) and mean wind speed (RR=1.814, 95%CI: 1.321-2.492) were positively correlated with SFTS risk, while altitude (RR=0.432, 95%CI: 0.230-0.829) and population density (RR=0.443, 95%CI: 0.207-0.964) were negatively correlated with SFTS risk.
Conclusions
SFTS in Zhejiang Province peaks from May to July. Middle-aged and elderly people and farmers are high-risk populations. Taizhou City, Shaoxing City, and Zhoushan City are high-incidence areas. Mean temperature, mean wind speed, altitude, and population density can all affect the risk of SFTS incidence.

ObjectiveThis paper aims to observe the role of Danlou tablet in treating coronary heart disease (CHD) with phlegm-stasis intermingling syndrome in minipigs by improving platelet function and explore the potential pharmacological mechanism of Danlou tablet in regulating platelet function by using proteomics technology. MethodsThirty Bama minipigs were randomly divided into a normal control group (6 pigs) and a high-fat diet group (24 pigs). After 2 weeks of high-fat diet feeding, the high-fat diet group was randomly subdivided into a model group, an atorvastatin group (1 mg·kg-1), and Danlou tablet groups (0.6 g·kg-1 and 0.3 g·kg-1). All groups continued to receive a high-fat diet for 8 weeks after the procedure. The normal control group was given a regular diet, underwent only coronary angiography, and did not receive an interventional injury procedure. The model group and each administration group were fed a high-fat diet. Two weeks later, they underwent a coronary angiography injury procedure. After the procedure, drugs were mixed into the feed every morning for 8 consecutive weeks, with the minipigs maintained on a continuous high-fat diet during this period. Quantitative proteomics technology was further used to study platelet proteins, and differential proteins were obtained by screening. Bioinformatics analysis was performed to analyze key regulatory proteins and biological pathways involved in the therapeutic effect of Danlou tablet on CHD with phlegm-stasis intermingling syndrome. ResultsCompared with the normal control group, the model group showed a significant increase in total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) of minipigs' serum (P<0.01), a significant shortening in prothrombin time of (PT) (P<0.01), a coagulation function index, and an increase in whole blood viscosity (P<0.01) and platelet aggregation rate (P<0.01). Moreover, the platelet morphology was altered, and the contents of endothelin-1 (ET-1) and nitric oxide (NO) were significantly increased (P<0.01). Hemodynamic parameters were obviously abnormal, including significantly decreased systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), left ventricular systolic pressure (LVSP), and left ventricular maximal positive dp/dt (LV+dp/dtmax) (P<0.01). Left ventricular maximal negative dp/dt (LV-dp/dtmax) was significantly increased (P<0.01). Besides, there were myocardial cell hypertrophy, obvious edematous degeneration, massive interstitial inflammatory cell infiltration, high degree of fibrosis, and coronary endothelial atherosclerosis. TC and TG levels in minipigs' serum were significantly reduced in Danlou tablet groups with 0.6 g·kg-1 and 0.3 g·kg-1 (P<0.05, P<0.01), compared with those in the model group. LDL-C was decreased in the Danlou tablet group with 0.6 g·kg-1 (P<0.05). The whole blood viscosity under low and high shear conditions was significantly reduced in the Danlou tablet group with 0.6 g·kg-1 (P<0.05). In groups with all doses of Danlou tablet, maximum aggregation rate (MAR) and average aggregation rate (AAR) were significantly decreased (P<0.05, P<0.01), and platelets' morphological changes such as pseudopodia extension were reduced. ET-1 levels in the serum were significantly reduced. In the Danlou tablet group with 0.6 g·kg-1, NO level in the serum was reduced (P<0.05). In groups with all doses of Danlou tablet, DBP and MAP were significantly increased (P<0.05). In the Danlou tablet group with 0.6 g·kg-1, LVSP and LV+dp/dtmax were significantly increased (P<0.05, P<0.01), and LV-dp/dtmax was significantly decreased (P<0.05). In groups with all doses of Danlou tablet, edematous degeneration in myocardial tissue was milder, and coronary artery lesion degree was significantly alleviated. Compared with the normal control group, there were 94 differentially expressed proteins in the model group, including 81 up-regulated and 13 down-regulated proteins. Compared with the model group, the Danlou tablet group with 0.6 g·kg-1 showed 174 differentially expressed proteins, including 100 up-regulated and 74 down-regulated proteins. A total of 30 proteins were reversed after Danlou tablet intervention. Bioinformatics analysis revealed that its pharmacological mechanism may exert anti-platelet activation, aggregation, and adhesion effects through biological pathways such as regulation of actin cytoskeleton, platelet activation pathway, Fcγ receptor-mediated phagocytosis, as well as proteins such as growth factor receptor-bound protein 2 (GRB2), Ras-related C3 botulinum toxin substrate 2 (RAC2), RAC1, and heat shock protein 90 alpha family class A member 1 (HSP90AA1). ConclusionDanlou tablet can effectively reduce platelet activation and aggregation, exerting a good therapeutic effect on CHD with phlegm-stasis intermingling syndrome in minipigs. Its pharmacological mechanism may involve regulating biological pathways such as actin cytoskeleton and platelet activation pathway, as well as proteins like GRB2, RAC2, RAC1, and HSP90AA1, thereby exerting a pharmacological effect in anti-platelet activation, aggregation, and adhesion.

ObjectiveTo establish an animal model of atrial fibrillation(AF) that accurately reflects the phlegm-heat and blood stasis(TRYZ) pathogenesis in traditional Chinese medicine. MethodsForty SPF-grade SD rats were randomly assigned using a random number table to the following groups:the control group, the TRYZ+AF group,the AF group and the TRYZ group, with ten rats in each group. The TRYZ+AF and TRYZ groups underwent a high-fat diet combined with intraperitoneal lipopolysaccharide(LPS) injection to simulate the pathological alterations of TRYZ syndrome. Groups TRYZ+AF and AF were induced with acetylcholine-calcium chloride(Ach-CaCl2) via caudal vein injection to induce AF. The control group received no intervention and was maintained under normal conditions. The modeling period lasted 3 weeks. Electrocardiography was used to assess AF episodes and duration, echocardiography evaluated left atrial dimensions and cardiac function, fully automated biochemical analyzer measured the levels of total cholesterol(TC), triglycerides(TG), high-density lipoprotein cholesterol(HDL-C) and low-density lipoprotein cholesterol(LDL-C), hemoreometer analyzed the whole blood viscosity, plasma viscosity, and whole blood reduced viscosity, a coagulation analyzer assessed prothrombin time(PT), activated partial thromboplastin time(APTT), thrombin time(TT), and fibrinogen(FIB), enzyme-linked immunosorbent assay(ELISA) was used to determine the levels of C-reactive protein(CRP), interleukin(IL)-1β, IL-6, IL-17, tumour necrosis factor(TNF)-α, matrix metalloproteinase-9(MMP-9), galectin-3(Gal-3), Collagen Ⅰ, and α-smooth muscle actin(α-SMA). Hematoxylin-eosin(HE) staining and Masson's trichrome staining were used to analyze pathological changes in atrial myocardium, Western blot was employed to detect MMP-9, Collagen Ⅰ and α-SMA protein expression in myocardial tissue, real-time quantitative polymerase chain reaction(Real-time PCR) evaluated fibrous factor gene expression levels. Changes in the TRYZ syndrome were assessed via body weight, tongue color[red(R), green(G), and blue(B)], and rectal temperature. Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was employed to detect differential metabolites between the control group and the TRYZ+AF group. ResultsFollowing three weeks of sustained modeling, compared with the control group, rats in the TRYZ+AF and the TRYZ groups exhibited reduced body weight, dry faeces, elevated rectal temperature, dark red tongue, decreased RGB values on the tongue surface, and markedly elevated TC and LDL-C levels(P<0.05, P<0.01). The TRYZ+AF, TRYZ, and AF groups exhibited significantly decreased TT, APTT and PT, along with markedly elevated whole blood viscosity and FIB(P<0.05, P<0.01). Rats in the TRYZ+AF and AF groups exhibited AF rhythm, markedly decreased heart rate, prolonged RR intervals, enlarged left atrium, and significantly reduced ejection fraction and shortening fraction(P<0.05, P<0.01). Serum levels of CRP, IL-1β, IL-6, IL-17, TNF-α, MMP-9, Gal-3, Collagen Ⅰ, and α-SMA were elevated in rats from the TRYZ+AF, TRYZ, and AF groups compared to the control group, with the most pronounced increase observed in the TRYZ+AF group(P<0.05, P<0.01). Histopathology revealed that the collagen fiber deposition in the atrial of rats in the TRYZ+AF, TRYZ and AF groups was higher than that in the control group(P<0.05, P<0.01). Western blot and Real-time PCR results further demonstrated that the protein and mRNA expression levels of MMP-9, Collagen Ⅰ and α-SMA in the myocardial tissue of the TRYZ+AF group were higher than those in the other three groups(P<0.05, P<0.01). Metabolomic analysis revealed 173 differentially expressed metabolites in the TRYZ+AF group and the control group, primarily enriched in pathways such as glycerophospholipid metabolism and glycolysis/gluconeogenesis. ConclusionThis study successfully establishes a rat model of AF integrated with the TRYZ syndrome, demonstrating the pathological process where the interactions of phlegm, heat and stasis jointly trigger tremor, this provides a reliable experimental tool for in-depth research into the biological basis of this disease syndrome.

To explore the advantages of traditional Chinese medicine (TCM) and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications (DMC), refine key pathophysiological insights and treatment principles, and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine, hosted by the China Association of Chinese Medicine, was held in Beijing, 2024. Experts in TCM, Western medicine, and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis, diagnostic and treatment challenges, and mechanism research related to DMC, ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development, research prioritization, and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM, strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.
