The development of traditional Chinese medicine (TCM) diagnosis and treatment has undergone multiple paradigms, evolving from sporadic experiential practices to systematic approaches in syndrome differentiation and treatment and further integration of disease and syndrome frameworks. TCM is a vital component of the medical system, valued alongside Western medicine. Treatment based on syndrome differentiation embodies both personalized treatment and holistic approaches; however, the inconsistency and lack of stability in syndrome differentiation limit clinical efficacy. The existing integration of diseases and syndromes primarily relies on patchwork and embedded systems, where the full advantages of synergy between Chinese and Western medicine are not fully realized. Recently, driven by the development of diagnosis and treatment concepts and advances in analytical technology, Western medicine has been rapidly transforming from a traditional biological model to a precision medicine model. TCM faces a similar need to progress beyond traditional syndrome differentiation and disease-syndrome integration toward a more precise diagnosis and treatment paradigm. Unlike the micro-level precision trend of Western medicine, precision diagnosis and treatment in TCM is primarily reflected in data-driven applications that incorporate information at various levels, including precise syndrome differentiation, medication, disease management, and efficacy evaluation. The current priority is to accelerate the development of TCM precision diagnosis and treatment technology platforms and advance discipline construction in this area.

Objective To investigate the relationship between cognitive function and sleep quality in patients with Alzheimer's disease(AD).Methods A case-control trial was conducted on 151 patients admitted to our department from May 2024 to December 2024.The patients with mild-to-moderate AD were assigned into the AD group(59 cases),and the cognitively normal patients in-to the control group(92 cases).All patients received neuropsychological assessment and sleep quality evaluation,including mini-mental state examination(MMSE),Montreal cognitive assess-ment(MoCA)and Pittsburgh sleep quality index(PSQI).The general clinical data and sleep qual-ity were compared between the two groups.Spearman correlation analysis was applied to analyze the relationship between cognitive function and sleep quality in the AD patients.Results The education level,MMSE score,MoCA score,instant story recall(ISR)score,delayed story recall(DSR)score,clock dawning test(CDT)score and Boston naming test score were significantly lower,while the activity of daily living(ADL)score was obviously higher in the AD group than the cognitively normal group(P＜0.05,P＜0.01).The AD patients had notably higher total score of PSQI and scores of sleep efficiency,nocturnal sleep disturbance and daytime dysfunction than the cognitively normal patients(P＜0.05,P＜0.01).In the AD patients,the total sleep time was positively correlated with the DSR score and the CDT score(r=0.300,P=0.021;r=0.308,P=0.018);hypnotic medication was negatively correlated with MMSE score,ISR score,and DSR score,and positively with ADL score(r=-0.320,P=0.013;r=-0.400,P=0.002;r=-0.331,P=0.010;r=0.355,P=0.006).Multiple linear regression analysis showed that benzodiazepines use and education level were independent influencing factors for cognitive function in the AD patients(P＜0.05,P＜0.01).Conclusion In AD patients,sleep quality is closely associated with cognitive function,as manifested by decreased sleep quality,reduced sleep efficiency,and worsened nocturnal sleep disturbances and daytime dysfunction.Administration of benzodiazepines may exacerbate cognitive impairment in AD patients.So,it is recommended that AD patients should be cautious about taking such drugs.

Objective To investigate the associations of immune cells,CD8+and CD4+T cells,and high-sensitivity C-reactive protein(hs-CRP)with cognitive function,and to explore the relation-ships among immunity,chronic inflammation,and Alzheimer's disease-related cognitive impair-ment.Methods A cross-sectional study was conducted on 101 patients with primary complaints of memory decline who visited the Alzheimer's Disease Clinic of Dongzhimen Hospital from June to December 2024.Mini-Mental State Examination(MMSE)and Delayed Story Recall Task(DSR)were performed to assess their cognitive function,and according to the results,they were divided into observation group(cognitively impaired,60 cases)and control group(cognitively normal,41 cases).Peripheral blood levels of CD8+T cells,CD4+T cells,and hs-CRP were compared between the two groups.Results The observation group exhibited significantly lower total scores and scores of different dimensions of MMSE and DSR scores,but notably higher activities of daily liv-ing scores than the control group(P＜0.05,P＜0.01).Serum hs-CRP level was obviously elevated in the observation group than the control group(P＜0.05).Binary logistic regression analysis revealed that CD8+T cells(OR=0.998,95％CI:0.996-1.000,P=0.038)and body mass index(OR=0.843,95％CI:0.719-0.990,P=0.037)were protective factors,while hs-CRP(OR=2.004,95％CI:1.215-3.306,P=0.006)was an independent risk factor for cognitive impairment.Spearman's rank correlation analysis showed a significant positive correlation between hs-CRP and CD4+T cells(P=0.011),but no significant association with CD8+T cells(P＞0.05).Conclusion Chronic inflammation and immune dysregulation synergistically contribute to cogni-tive decline.Hs-CRP may serve as a potential screening biomarker for cognitive impairment in pri-mary care settings.

Objective To establish the fingerprint of Xuemai Shutong granules by UPLC-ELSD and determine the contents of 9 components in the preparation simultaneously.Methods The UPLC-ELSD was used to establish the fingerprint of Xuemai Shutong granules,and determine the content of its 9 components.The similarity evaluation system,systematic,cluster analysis,principal component analysis and orthogonal partial least squares discriminant analysis were used to evaluate the quality of different batches of preparation.Results The similarity degrees of UPLC-ELSD fingerprints of 11 batches of Xuemai Shutong granules were from 0.929 to 0.978,17 common peaks were calibrated,of which 11 peaks were identified:peak 3(notoginsenoside R1),peak 4[ginsenoside Rg,(Re)],peak 5(notoginsenoside R2),peak 6(ginsenoside Rb,),peak 9(astragaloside Ⅳ),peak 10(ginsenoside Rk3),peak 11(ginsenoside Rh4),peak 12[20(S)-ginsenoside Rg3],peak 13[20(R)-ginsenoside Rg3],peak 14(ginsenoside Rk1),peak 15(ginsenoside Rg5).The stoichiometric analysis divided 11 batches of samples into 2 classes,and the 2 principal components in PCA analysis reflected the information of 17common peaks,10 peaks which affected the quality difference are screened out.The linear relationship of the 9 components was good in their respective quality ranges in the content analysis(r＞0.999 2),the average recovery rate were between 95.02％-97.78％and the RSD were 0.69％-1.70％(n=6).The contents of notoginsenoside R1,notoginsenoside R2,ginsenoside Rb1,astragaloside Ⅳ,ginsenoside Rh4,20(S)-ginsenoside Rg3,20(R)-ginsenoside Rg3,ginsenoside Rk1 ginsenoside Rg5 in the 11 batches of Xuemai Shutong granules were 0.087 5-0.187 6,0.494 3-0.688 6,0.448 1-0.705 5,0.192 2-0.270 8,1.492 5-2.077 6,0.316 0-0.463 8,0.254 5-0.382 0,0.117 6-0.163 9,3.407 7-4.706 4 mg·g-1,respectively.Conclusions The established fingerprint and content determination method was accurate and reliable,which can improve the quality standard of Xuemai Shutong granules,and provide reference for its overall quality evaluation.

Objective To investigate the protective effect and mechanism of apigenin on the liver of hyperlipidemic mice based on metabolomics methods.Methods C57BL/6 mice were randomly divided into four groups including blank,model,fenofibrate(26.0 mg·kg-1),and apigenin(12.5 mg·kg-1)groups,with six mice in each group.Each group was treated with corresponding drug by gavage once a day for five days.On the third day of administration,the mouse model of acute hyperlipidemia was induced by a single intramuscular injection of Triton WR-1339(5 mL·kg-1)at a concentration of 0.12 g·mL-1.Biochemical indexes such as TC and TG in mice serum were measured by using a fully automatic microplate reader.HE staining was used to observe pathological changes in liver tissue.UPLC-Q-TOF-MS/MS technology was applied to analyze liver tissue samples.Differential metabolites were screened by using multivariate statistical analysis methods such as PCA,PLS-DA,and OPLS-DA.Then we ran the mass spectrometry information of these metabolites through online databases including HMDB,METLIN and KEGG,as well as combined with relevant literature to obtain the potential differential metabolites.The identified potential differential compounds were imported into the MetaboAnalyst platform for metabolic pathway analysis.Results Compared with the blank group,TC and TG levels in mice serum of model group increased obviously(P＜0.01).Irregular arrangement of liver cells,fat vacuoles and infiltration of inflammatory cells were found.Compared with the model group,TC and TG levels in mice serum of apigenin group decreased(P＞0.05).Fatty lesions in liver tissue were significantly improved,and fat vacuoles and inflammatory cell infiltration were significantly reduced.A total of 35 differential metabolites were screened.Twenty-six differential metabolites showed callback trend after apigenin treatment.Eight metabolic pathways were obviously affected,among which pantothenate and CoA biosynthesis,as well as arachidonic acid metabolism are two main metabolic pathways(P＜0.05).Conclusion Apigenin exhibits a certain protective effect on liver of hyperlipidemic mice,and its mechanism may be related to regulating liver inflammatory response and lipid metabolism-related pathways.

Objective:To explore the clinical application value of limb remote ischemic postconditioning (LRIPC) in patients with acute cerebral infarction after recanalization.Methods:A total of 78 patients with acute cerebral infarction admitted to the First Affiliated Hospital of Shantou University Medical College from June 2017 to March 2019 were selected. According to the random number table method, they were divided into the observation group with 39 cases (LRIPC + conventional medical treatment) and the control group with 39 cases (conventional medical treatment). The National Institutes of Health Stroke Scale (NIHSS) and Montreal Cognitive Assessment scale (MoCA) scores, the changes of cerebral blood perfusion, cerebral infarction volume and the levels of nerve function indexes before and after the treatment were compared and analyzed.Results:After the treatment, the NIHSS scores in the observation group were lower than thosein the control group, and the MoCA scores were higher than those in the control group, the differences were statistically significant ( P<0.05). After the treatment, the mean transit time of cerebral blood flow in the observation group was shorter than that in the control group, while the regional cerebral blood flow and regional cerebral blood volume were higher than those in the control group, the differences were statistically significant ( P<0.05). After the treatment, the volume of cerebral infarction in the observation group was lower than that in the control group ( P<0.05). After the treatment, the levels of matrix metalloproteinase 9 and S-100B protein in the observation group were lower than those in the control group: (142.45 ± 36.23) mg/L vs. (176.89 ± 42.63) mg/L, (2.52 ± 0.46) μg/L vs. (3.61 ± 0.75) μg/L; and the level of nerve growth factor was higher than that in the control group: (143.49 ± 10.58) μg/L vs. (124.96 ± 13.62) μg/L, the differences were statistically significant ( P<0.05). Conclusions:LRIPC can improve the nerve functions, cognitive functions andreduce the volume of cerebral infarction by improving cerebral blood flow. It also has a good effect on alleviating the neurological functional impairment after vascular recanalization.
