As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

OBJECTIVE To explore the mechanism of action of Qingre huatan huoxue decoction against atherosclerosis （AS）based on macrophage polarization. METHODS Using atorvastatin served as the positive control， the drug-containing serum of the Qingre huatan huoxue decoction was prepared to treat RAW264.7 macrophages. Macrophage viability， apoptosis rate， and the fluorescence intensities of CD86 and CD206 were measured， along with the levels of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）. Apolipoprotei n E-deficient （ApoE －/－ ） mice （AS model mice） fed with a high-fat diet were randomly assigned to model group， atorvastatin group （2.6 mg/kg）， and low-， medium- and high-dose groups of Qingre huatan huoxue decoction （90， 180， 360 mg/kg）， respectively. C57BL/6J mice fed with a standard diet served as the normal control group， with 10 mice per group. The treatment group mice were administered the corresponding drugs intragastrically， once daily， for 8 consecutive weeks. Serum levels of TNF-α and IL-1β were measured in all groups. Lipid deposition in the aorta （assessed by the percentage of plaque in the entire aorta and aortic root） and morphological changes in the aortic root were observed. Expression levels of CD86 and CD206 in aortic tissue， as well as the protein expression levels of inducible nitric oxide synthase （iNOS）， arginase-1 （Arg-1）， AMP-activated protein kinase （AMPK）， phosphorylated AMPK （p-AMPK）， and peroxisome proliferator-activated receptor γ （PPAR-γ） in aortic tissues were all detected. RESULTS Cell experiment results showed that， at concentrations of 5-100 μg/mL， the drug-containing serum of the Qingre huatan huoxue decoction significantly increased RAW264.7 cell viability （ P ＜0.05）. The drug-containing serum of the Qingre huatan huoxue decoction at concentrations of 10， 50， and 100 μg/mL， along with atorvastatin， significantly reduced apoptosis rates， CD86 fluorescence intensity， and TNF-α and IL-1β levels in RAW264.7 cells， while markedly enhancing CD206 fluorescence intensity （ P ＜0.05）. Animal experiment results showed that， compared with the model group， all dosage groups of Qingre huatan huoxue decoction and the atorvastatin group showed significantly reduced/down-regulated levels of TNF-α and IL-1β in serum， along with decreased aortic total and root plaque percentages， CD86 expression， and iNOS protein expression. CD206 expression and Arg-1， p-AMPK/AMPK， PPAR-γ protein expression were significantly up-regulated （ P ＜0.05）. Pathological morphology of the aorta showed varying degrees of improvement. CONCLUSIONS The formula of Qingre huatan huoxue decoction exerts its anti-AS effects by regulating macrophage polarization， increasing the proportion of M2 macrophages， thereby effectively inhibiting AS plaque formation and reducing inflammatory responses.

ObjectiveTo genotype the specimens from hand-foot-and-mouth disease (HFMD) cases in Dehong Prefecture, Yunnan Province in 2023 by gene sequencing, and to analyze the genetic characteristics of Coxsackievirus A4 (CVA4), CVA6, CVA10, CVA16 and enterovirus A71 (EV-A71), so as to clarify the serotypes of enteroviruses causing endemic HFMD and the genotype composition of CVA4, CVA6, CVA10, CVA16 and EV-A71 prevalent in HFMD, and to provide baseline genotype data for monitoring the dynamic changes of the five virus genotypes. MethodsStool specimens from HFMD cases in Dehong Prefecture in 2023 that tested positive for EV-A71, CVA16 and other enteroviruses by real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) were first subjected to gene sequencing and typing of the VP4/VP2 junction region to determine the viral types. Subsequently, the complete VP1 gene of each virus was amplified in two segments using group-specific VP1 gene primers corresponding to enterovirus groups (i.e., enterovirus group A, B, and C) and sequenced (group A virus: primers 486/488 and 487/489, group B virus: primers 490/492 and 491/493, group C virus: primers 494/496 and 495/497). The representative reference sequences of VP1 genes for CVA4, CVA6, CVA10, CVA16 and EV-A71 were downloaded from the literature, and the VP1 gene phylogenetic tree was constructed using MEGA 6.0 software for genetic characterization. ResultsA total of 256 stool specimens were collected from HFMD cases in Dehong Prefecture in 2023, of which 94 tested positive for nucleic acid by RT-qPCR, yielding a positive rate of 36.72%. Of the 94 positive specimens, 83 were identified as group A viruses, and were classified into 5 serotypes (17 strains of CVA4, 3 of CVA6, 6 of CVA10, 49 of CVA16, and 8 of EV-A71). Nine strains were group B viruses, comprising 2 serotypes: 2 strains of echovirus type 3 (E3) and 7 strains of Coxsackievirus B type 5 (CVB5). The remaining 2 strains were group C viruses, both identified as poliovirus type 3 (PV3). Genetic analyses of the VP1 region showed that all 17 CVA4 strains were identified as subgenotype C2, all 3 CVA6 strains as subgenotype D3a, all 6 CVA10 strains as genotype C. Among the 49 CVA16 strains, 46 were identified as subgenotype B1a and 3 as subgenotype B1b, and all 8 EV-A71 strains were identified as subgenotype C4a. ConclusionIn 2023, group A viruses dominated the pathogenic spectrum of HFMD in Dehong Prefecture. Among them, CVA16 had the highest positivity rate. Genetic characteristic analyses showed that CVA4, CVA6, CVA10 and EV-A71 were each composed of a single genotype (subgenotype), while CVA16 was composed of two subgenotypes (B1a and B1b), with B1a being the predominant one. It is recommended that molecular epidemiological surveillance of HFMD pathogens, particularly group A viruses, be continuously strengthened in Dehong Prefecture.

This article summarized the clinical experience of national TCM master Zhang Zhen in treating gastroesophageal reflux cough by applying the theory of"dredging and regulating qi".Professor Zhang Zhen believes that the pathogenesis of gastroesophageal reflux cough lies in the abnormal ascending and descending of qi movement in the viscera.Specifically,it is manifested as weakness of the spleen and stomach,dysfunction of the pivot mechanism,failure of the liver to dredge and disperse,failure of the lung qi to descend,insufficiency of kidney yang,and failure of the kidney to receive qi.Clinically,the treatment method of dredging and regulating qi is adopted,and the Shutiao Decoction is used as the basic prescription.The disease is treated from three aspects,namely strengthening and regulating the spleen and stomach,soothing the liver and purifying the lung,and tonifying the kidney and helping it receive qi.The regulation of the qi movement of the whole body is organically combined with that of the local areas to jointly smooth the operation of the qi movement throughout the body.It is hoped that this can provide references and ideas for the treatment of gastroesophageal reflux cough in TCM.

Objective The aim of this study was to analyze the incidence and mortality of lymphoma and their changing trends in cancer registration areas of Liaoning Province from 2016 to 2020,and to provide data support for lymphoma prevention and treatment.Methods The data of tumor registration areas in Liaoning province from 2016 to 2020 were collected and sorted out,and the crude incidence,mortality,China standardized incidence and mortality,world standardized incidence and mortality,and cumulative rate of lymphoma were calculated;Joinpoint 5.0.2 software was used to analyze the changing trends of the above indicators from 2016 to 2020.Results From 2016 to 2020,the crude incidence of lymphoma in tumor registration areas of Liaoning Province was 7.43/100,000,age-standardized incidence by Chinese standard population(ASIRC)was 4.07/100,000,and age-standardized incidence by world standard population(ASIRW)was 3.95/100,000;the crude mortality was 4.29/100,000,age-standardized mortality by Chi-nese standard population(ASMRC)was 2.07/100,000,and age-standardized mortality by world standard population(ASMRW)was 2.02/100,000.The ASIRC and ASMRC were higher in males(4.62/100,000 and 2.53/100,000,respectively)than in females(3.56/100,000 and 1.61/100,000,respectively),also higher in urban areas(4.65/100,000 and 2.32/100,000,respectively)than in rural areas(2.46/100,000 and 1.65/100,000,respectively).The incidence and mortality of lymphoma increased with age.The in-cidence reached its peak in the 70-79 age group,and the mortality reached its peak in the 80+age group.From 2016 to 2020,the crude incidence of lymphoma increased from 6.86/100,000 to 8.22/100,000,with a statistically significant trend(APC=5.06％,95％CI;1.13％-9.14％,P=0.026).ASIRC increased from 4.01/100,000 to 4.45/100,000,with no statistical significance(P＞0.05).The crude mortality increased from 3.85/100,000 to 4.53/100,000,while ASMRC decreased from 2.02/100,000 to 2.01/100,000,with no statistically significant trend in the two changes(P＞0.05).Conclusions The incidence and mortality of lymphoma in cancer registration areas of Liaoning Province are higher in men than those of women,and higher in cities than those in rural areas,and reach the peak in the elderly group.The prevention and control of key populations and health management should be strength-ened,especially pay attention to the health needs of the elderly population,and explore possible directions for multidisciplinary collab-orative diagnosis and treatment to reduce the disease burden.

AIM:To observe the neuroprotective effects of total saponins of Trillium tschonoskii Maxim(TST)on rats with vascular dementia(VD)and explore the drug's impact on astrocytes and the Sonic Hedgehog(Shh)pathway as well as its mechanisms of action.METHODS:A rat model of vascular dementia was established by bilateral common carotid artery occlusion.Subsequently,the rats were randomly divided into four groups:donepezil hydrochloride group,TST group,model group,and sham group,with 18 rats in each group.After 5 weeks of gavage,samples were collected.Cognitive function was evaluated by the water maze test.Histopathological changes in brain tissue were examined with HE and Nissl staining.The ultrastructure of astrocytes was analyzed by transmission electron microscopy.The localization and expression of the neuronal nuclear antigen(NeuN),glial fibrillary acidic protein(GFAP),Shh,and glioma-associated oncogene homolog 1(Gli1)were identified using immunohistochemistry.Immunofluorescence was also employed to exam-ine the expression of NeuN and GFAP.Finally,Western blot analysis was used to measure the protein levels of NeuN,GFAP,Shh,Patched 1(Ptch1),Gli1,Bax,Bcl-2,tumor necrosis factor-α(TNF-α),and interleukin-10(IL-10)in the hippocampus.RESULTS:Compared to the sham group,the model rats demonstrated prolonged escape latency,disorga-nized and loosened neuronal arrangement in the hippocampus and cortex,reduced Nissl bodies,and significant neuronal damage.Astrocytes displayed chromatin aggregation,swollen mitochondria with disrupted cristae structures,and swollen endoplasmic reticulum regions.The expression of NeuN,Shh,and Gli1 positive cells significantly decreased,while GFAP positive cells significantly increased.Additionally,the protein levels of NeuN,Shh,Ptch1,Gli1,IL-10,and Bcl-2 in the hippocampus were reduced(P＜0.05),whereas those of GFAP,Bax,and TNF-α were elevated(P＜0.01).Com-pared to the model group,the donepezil hydrochloride and TST groups effectively improved the aforementioned indicators.CONCLUSION:Total saponins of trillium tschonoskii maxim can effectively alleviate pathological damage to neurons in VD rats,thereby improving learning and memory abilities.The underlying mechanisms may involve inhibiting the overacti-vation of astrocytes,activate the Shh/Ptch1/Gli1 signaling pathway,suppress neuroinflammation,and reduce neuronal apoptosis.

OBJECTIVE: Gastric cancer (GC) is one of the most common malignancies seen in clinic and requires novel treatment options. Morin is a natural flavonoid extracted from the flower stalk of a highly valuable medicinal plant Prunella vulgaris L., which exhibits an anti-cancer effect in multiple types of tumors. However, the therapeutic effect and underlying mechanism of morin in treating GC remains elusive. The study aims to explore the therapeutic effect and underlying molecular mechanisms of morin in GC. METHODS: For in vitro experiments, the proliferation inhibition of morin was measured by cell counting kit-8 assay and colony formation assay in human GC cell line MKN45, human gastric adenocarcinoma cell line AGS, and human gastric epithelial cell line GES-1; for apoptosis analysis, microscopic photography, Western blotting, ubiquitination analysis, quantitative polymerase chain reaction analysis, flow cytometry, and RNA interference technology were employed. For in vivo studies, immunohistochemistry, biomedical analysis, and Western blotting were used to assess the efficacy and safety of morin in a xenograft mouse model of GC. RESULTS: Morin significantly inhibited the proliferation of GC cells MKN45 and AGS in a dose- and time-dependent manner, but did not inhibit human gastric epithelial cells GES-1. Only the caspase inhibitor Z-VAD-FMK was able to significantly reverse the inhibition of proliferation by morin in both GC cells, suggesting that apoptosis was the main type of cell death during the treatment. Morin induced intrinsic apoptosis in a dose-dependent manner in GC cells, which mainly relied on B cell leukemia/lymphoma 2 (BCL-2) associated agonist of cell death (BAD) but not phorbol-12-myristate-13-acetate-induced protein 1. The upregulation of BAD by morin was due to blocking the ubiquitination degradation of BAD, rather than the transcription regulation and the phosphorylation of BAD. Furthermore, the combination of morin and BCL-2 inhibitor navitoclax (also known as ABT-737) produced a synergistic inhibitory effect in GC cells through amplifying apoptotic signals. In addition, morin treatment significantly suppressed the growth of GC in vivo by upregulating BAD and the subsequent activation of its downstream apoptosis pathway. CONCLUSION Morin suppressed GC by inducing apoptosis, which was mainly due to blocking the ubiquitination-based degradation of the pro-apoptotic protein BAD. The combination of morin and the BCL-2 inhibitor ABT-737 synergistically amplified apoptotic signals in GC cells, which may overcome the drug resistance of the BCL-2 inhibitor. These findings indicated that morin was a potent and promising agent for GC treatment.
