According to traditional Chinese medicine （TCM） theory， impaired spleen transportation function disrupts nutrient distribution， causing metabolic accumulation of lipids that transform into pathogenic phlegm-dampness. These pathological factors disseminate through the San Jiao and obstruct meridian pathways， ultimately forming the pathogenesis described as "all disorders involve phlegm". Phlegm and dampness share common pathogenic origins but manifest distinct clinical manifestations. Dampness， as the precursor， may congeal into phlegm， while existing phlegm accumulation can further exacerbate dampness stagnation， thereby establishing a self-perpetuating pathological cycle. Modern medical research has confirmed that the essence of "phlegm-dampness" syndrome is closely associated with energy metabolism disorders， serving as a common pathological basis for metabolic syndrome， type 2 diabetes mellitus， atherosclerosis， and other major chronic diseases. As a crucial vehicle for medical experimental research， disease-syndrome combination animal models serve as an indispensable means to advance the modernization of TCM. Currently， based on classical theories such as "rich and greasy foods produce phlegm" and "physical coldness combined with cold consumption causes external pathogens to invade the skin and hair， thereby generating internal dampness"， researchers primarily employ two paradigms to construct animal models of phlegm-turbidity， dampness obstruction， and phlegm-dampness syndromes： the first involves simulating TCM etiological factors （through methods like dietary irregularities， imblanace between work and rest， and combined internal-external dampness exposure）， while the second combines disease with syndrome differentiation （inducing pathological changes through physical， chemical， or biological interventions）. Through comprehensive evaluation incorporating macroscopic observation and microscopic index detection， model animals undergo systematic biological and pathological assessment， with further syndrome type verification achieved via the "prescription-based syndrome detection" approach. However， existing models still exhibit significant deficiencies in both the standardization of modeling methodologies and the systematization of evaluation criteria. This paper reviews the strategies for constructing "phlegm-dampness" syndrome animal models and their corresponding evaluation indices， focusing on the pathological correlations among different modeling approaches. The aim is to provide methodological guidance for research on TCM syndromes related to "phlegm-dampness" syndrome and to support the development of TCM therapies for resolving phlegm and eliminating dampness. This study not only contributes to advancing the standardization of TCM syndrome research but also provides crucial technical support for the modernization of TCM.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

Objective:To investigate the correlation between rectal colonization of carbapenem resistant Klebsiella pneumoniae（CRKP）and bloodstream infections（BSI）using molecular epidemiological analysis. Methods:Patients admitted to the Intensive Care Unit（ICU），Hematology Department，and Neurosurgery Department of the First Hospital of Jiaxing from January 2022 to December 2024，were enrolled. Rectal CRKP colonization screening was performed for all participants，with concurrent monitoring for BSI.Whole genome sequencing of CRKP strains in the intestine and blood flow of patients with CRKP rectal colonization and CRKP-BSI was performed using the Illumina NovaSeq PE150 sequencing platform，and samples were genotyped based on the PubMLST database. MLST 2.0 was applied for multi site sequence typing，VFDB online database was used to analyze virulence genes，ResFinder was used to analyze resistance genes，and whole genome sequences were imported into BioNumerics software for core genome multi site sequence typing and clustering analysis. Using the BacWGSTdb database to construct a phylogenetic tree based on genomic SNPs，and the homology between CRKP rectal fixed plants and corresponding BSI-CRKP infected plants were analyzed.Results:A total of 772 patients were included，including 78 cases with positive results in rectal CRKP colonization screening（10.1%）and 694 cases without rectal CRKP colonization（89.9%）. The CRKP-BSI rate in rectal CRKP colonization patients was significantly higher than that in non-CRKP colonization patients［19.2%（15/78） vs. 5.5%（38/694）， χ2=20.749， P<0.001］. Analysis of CRKP rectal colonization strains and bloodstream infection strains in 15 patients with CRKP rectal implantation and CRKP-BSI revealed that ST11 type was the main strain（ n=10），followed by ST37 type（ n=3），with all carrying multiple β-lactam and carbapenem producing enzyme resistance genes.The distribution of virulence genes showed that CRKP strains carried multiple virulence genes，with iroE being ubiquitous，followed by iucA/ B/ C/ D， rmpA2，rmpA，and iroN. All ST11-type CRKP strains exhibited hypervirulent characteristics. Capsular serotyping analysis showed that the predominant type of CRKP colonization and infection strains was KL64. The results of cgMLST and SNP clustering analysis showed that CRKP rectal fixed plants exhibited homology with blood flow infected plants. Moreover，two clusters of CRKP rectal colonization strains with significant homology were found to cluster together among 15 patients. Conclusions:Rectal colonization of CRKP is an important risk factor for the occurrence of BSI-CRKP in hospitals，and ST11 hypervirulent CRKP is the main type. It is recommended to screen high-risk patients for CRKP to reduce the risk of BSI-CRKP.

[Summary]Diabetic peripheral neuropathy(DPN)is one of the most common complications of diabetes.The blood nerve barrier(BNB)is a barrier structure located in peripheral nerve tissue,protecting nerve tissue from toxic substances in the blood and maintaining material exchange and information transmission between nerves and blood.Studies have shown that changes in BNB may be the initial event leading to the occurrence of DPN.After BNB is destroyed,blood-borne pathogens can directly damage peripheral nerves and cause DPN.This article will review the physiological and pathological characteristics of BNB,the relationship between BNB and DPN,and the research progress in targeting BNB for the treatment of DPN.

Objective To observe the value of MR lymphangiography(MRL)radiomics for evaluating central conducting lymphatic anomaly(CCLA).Methods Sixty-one patients with complex lymphatic anomaly,including 41 CCLA(group A),20 non-CCLA(generalized lymphatic anomaly and Gorham-Stout disease)and 20 subjects with normal thoracic duct(group B,n=38)were retrospectively enrolled.Cervical and thoracic(combined with abdominal if necessary)MRL was acquired using three-dimensional heavily T2W fast spin echo sequence.ROI was delineated along overall thoracic duct,and radiomics features were extracted.Data sets of group A and B were divided into K subsets using 5-fold cross-validation.The union of(K-1)subset was always used as training set,while the other subsets were used as validation set.Radiomics model was constructed based on support vector machine(SVM)algorithm.Receiver operating characteristic curve was drawn,the area under the curve(AUC)was calculated to evaluate the efficacy of SVM model for assessing CCLA.Results The proportions of bifurcation,cystoid change and extension of main thoracic duct,and extension of terminal thoracic duct in group A were all higher,while of normal main and terminal thoracic duct in group A were both lower than those in group B(all P＜0.05).No significant difference of proportions of multiple thoracic ducts,dextral thoracic duct,part of thoracic duct invisible,multiple terminal thoracic ducts,cystoid change of terminal thoracic duct nor terminal thoracic duct pampiniform was found between groups(all P＞0.05).The sensitivity,specificity,accuracy,positive predictive,negative predictive and AUC of SVM model for evaluating CCLA in training set was 78.95％,97.56％,88.61％,96.77％,83.33％and 0.920,respectively,which in validation set was 78.95％,83.57％,82.28％,83.33％,81.40％and 0.833,respectively.Conclusion MRL radiomics could be used to effectively evaluate CCLA.

Abstract OBJECTIVE To introduce the developing procedure of reference standards of nitrosamines by taking 1-methyl-4-nitrosopiperazine(MNP) as example and discuss the problems needing attention when using nuclear magnetic resonance(NMR) quantitative method. METHODS The structure of the material was confirmed by mass spectrometry, infrared spectrum and nuclear magnetic methods. In terms of quantitative assessment, the purity of the material was analyzed by HPLC, and the water was investigated. The content of MNP was determined by mass balance method, the content of the material was verified by NMR quantitative method. RESULTS MNP was consistent with its structure. In the quantitative NMR investigation, it was found that the use of different internal standards had a great impact on the calibration results. CONCLUSION Since MNP is basic, it is easy to reduce the final determination result by using an acidic internal standard in NMR quantitative analysis. Therefore, it is suggested that an appropriate internal standard should be selected for this kind of sample in the process of NMR quantitative determination.

Fenugreek is a kind of Chinese herbal medicine with great development prospects.At present,there are many modern reports on its components extraction,quality standards,processing technology and pharmacological effects.However,there is still a lack of research on sorting out and analyzing the relevant ancient records,and people's herbological cognition of fenugreek is still controversial and incomplete.In this study,through systematic review and analysis of ancient records,the names,original plant,processing methods and properties(including nature,flavor,meridian tropism,action,application,toxicity and contraindication)of fenugreek were comprehensively verified for the first time,which provided a herbological reference for further development,utilization and in-depth study of Fenugreek.It is found that fenugreek has several names such as Kudou,Luba,Huba and Jidou.Based on analyzing the descriptions and pictures of fenugreek original plant in ancient records,there is a strong likelihood that the ancient and modern medicinal fenugreek belong to the same species.In addition to the current common method of stir-frying with salt solution,the ancient books also recorded eight processing methods of fenugreek,such as stir-frying,steaming,baking,and calcining.According to the research of properties,it is found that fenugreek is warm-hot in nature,bitter,sweet,and pungent in flavor,and attributive to the kidney,stomach,liver and bladder meridians.In addition to the efficacy recorded in pharmacopoeia,this study also complemented fenugreek's actions of"improving hearing and eyesight,guiding fire to origin"and application of"fullness and discomfort in abdomen and hypochondrium".According to the textual research of toxicity and contraindication,fenugreek has been recorded as non-toxic in the past dynasties,but it should be used cautiously in the excess-heat syndrome,Yin deficiency syndrome,and pregnant women.
