Objective:To explore the metabolic regulations of different Traditional Chinese Medicine (TCM) syndromes in the diabetic patients with high risk for foot ulceration.Methods:Based on gas chromatography-mass spectrometer and multi-dimensional data processing methods, the metabolomics analysis was used to compare the serum metabolites profile of healthy people (32 cases) and the high-risk foot patients in Cold and Blood Stagnation syndrome (44 cases), Heat-toxin hurting Yin syndrome (54 cases), and Qi-Blood deficiency syndrome (33 cases), who were hospitalized at Shanghai TCM-Integrated Hospital from Apirl to December, 2018.Results:This study suggested that compared with healthy people, the diabetic patients with high risk for foot ulceration showed significantly lower serum level of urea [(2.41 ± 1.57)×10 5vs. (3.32 ± 2.10)×10 5], L-leucine [(4.94 ± 3.15)×10 5vs. (6.39 ± 3.57)×10 5], aspartic acid [(3.94 ± 4.48)×10 5vs. (9.62 ± 6.93)×10 5], 9H-purine [(1.74 ± 1.95)×10 5vs. (3.34 ± 2.23)×10 5] ( P<0.05 or P<0.01), while higher level of d-Glucose [(3.72 ± 1.71)×10 5vs. (2.21 ± 1.32)×10 5] and d-glucopyranose [(3.32 ± 2.10)×10 5vs. (1.35 ± 1.43)×10 5] ( P<0.01). Energy metabolism, amino acid metabolism and sugar metabolism were mainly involved. the content of L-tyrosine in the group of patients with Cold and Blood Stagnation syndromewas significantly higher than that in healthy people. The urea, purine, leucine, aspartic acidcontent in patients of Heat-toxin hurting Yin syndrome were significantly lower than that in healthy people. The purine content in patients of Qi and Blood Deficiency Syndrome was significantly lower than that in healthy people. Compared with the syndrome of Heat-toxin hurting Yin syndrome, patients in Cold and Blood Stagnation syndrome showed a significantly higher content of beta-1-galactopyranoside and butanoic acid. Compared to the Qi-Blood deficiency syndrome, serum urea level in patients of Heat-toxin hurting Yin syndrome was significantly higher than those in the patients of other two TCM syndromes. Conclusions:The serum metabolomics profiling differentiate three TCM-syndrome in high-risk DF patients, which can provide objective basis for clinical TCM syndrome differentiation and treatment of high-risk diabetic foot patients.

Malignant tumors are one of the main causes of death from chronic diseases in China,and their incidence and mortality rates show an in-creasing trend year by year.Advanced non-surgical treatment of malignant tumors is an important means of improving patients'prognosis and en-hancing their quality of life.The traditional Chinese medicine Ganoderma lucidum has anti-tumor ef-fects and plays a role in the treatment of many ma-lignant tumors.In this paper,a systematic review of the effects of Ganoderma lucidum active ingredi-ents on tumors has been conducted at home and abroad in the past five years to explore the anti-tu-mor mechanism of Ganoderma lucidum active in-gredients and to lay a theoretical foundation for the application of Ganoderma lucidum active ingre-dients in clinical practice.

OBJECTIVE:To evaluate the effectiveness and safety of repaglinide combined with metformin versus glimepiride combined with metformin in the treatment of type 2 diabetes mellitus (T2DM),and to provide evidence-based reference for the clinic. METHODS:Retrieved from CJFD, VIP, Wanfang database, PubMed, Embase, Medline and Cochrane Library, randomized controlled trials (RCTs) about therapeutic efficacy (HbA1c, FPG, 2 hPG) and safety (the incidence of ADR,hypoglycemia and gastrointestinal reaction)of repaglinide combined with metformin(trial group)versus glimepiride combined with metformin(control group)in the treatment of T2DM were collected. Meta-analysis was performed by using Rev Man 5.2 statistical software after data extraction and quality evaluation with Cochrane systematic evaluation manual. RESULTS:A total of 12 RCTs were included,involving 957 patients. Results of Meta-analysis showed that the decrease of 2 hPG in trial group was significantly better than control group,with statistical significance [MD=-0.70,95％CI(-1.02,-0.38),P<0.001]. There was no statistical significance in the decrease of HbA1c [MD=0.00,95％CI(-0.24,0.25),P=0.98] or FPG [MD=0.10,95％CI(-0.17,0.36),P=0.47],the incidence of ADR [OR=0.54,95％CI(0.28,1.06),P=0.07],hypoglycemia [OR=0.52,95％CI(0.13,2.06),P=0.35] or gastrointestinal reactions [OR=0.60,95％CI(0.15,2.41),P=0.47] between 2 groups. CONCLUSIONS:Repaglinide combined with metformin is better than glimepiride combined with metformin in reducing 2 hPG,but both of them have similar safety.

Objective:To analyze the role of dandelion and mulberry leaf in the progression of acute myeloid leukemia(AML)by network pharmacology,and to clarify the active components and their mechanisms in treating AML.Methods:The active components of dandelion and mulberry leaf were screened by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP).The targets were predicted by SwissTargetPrediction Database.The AML-related genes and protein targets were retrieved from the SymMap Database,the GeneCards Human Gene Database,the DisGeNET Database,and the Online Mendelian Inheritance in Man(OMIM)Database.The AML-related genes and target genes of dandelion and mulberry leaf were compared by comparative analysis and were identify by the enrichment genes,followed by Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis.The drug-active component-target network and protein-protein interaction(PPI)network were constructed by Cytoscape 3.8.0 software,and the core genes were selected by CytoNCA plugin;the molecular docking was conducted by AutoDock software.Results:After filtering by databases,39 active components were identified,and 148 common targets between dandelion-mulberry leaf and AML were collected.The GO functional enrichment analysis mainly involved cytokine-mediated signaling pathways,positive regulation of kinase activity,and oxidative stress responses.The KEGG signaling pathway enrichment analysis focused on the phosphatidylinositol 3 kinase/protein kinase B(PI3K-AKT)signaling pathway,the tumor necrosis factor(TNF)signaling pathway,and the Janus kinase/signal transducer and activator of transcription(JAK-STAT)signaling pathway.The key targets were identified by topological analysis including signal transducer and activator of transcription 3(STAT3),epidermal growth factor receptor(EGFR),protein kinase B1(AKT1),recombinant human epidermal growth factor(EGF),vascular endothelial growth factor A(VEGFA),oncogene MYC,tumor protein P53(TP53),mitogen-activated protein kinase 3(MAPK3),cysteiny asparate specific protease-3(CASP3),oncogene SRC,heat shock protein 90 alpha family class A member 1(HSP90AA1),tenascin XB1(CTNNB1),phosphoinositide kinase-3 catalytic subunit alpha(PIK3CA),interleukin 6(IL-6),TNF,mitogen-activated protein kinase 1(MAPK1),and phosphatidylinositide kinase-3 regulatory subunit 1(PIK3R1).The molecular docking results showed the highest affinity pairing to be taraxerol with MYC(-8.74 kcal·mol-1),and quercetin,kaempferol,luteolin,and artemetin demonstrated good binding affinities with various targets.Conclusion:The main active components of dandelion-mulberry leaf,such as quercetin,taraxerol,kaempferol,luteolin,and artemetin,may exert the anti-AML effect by regulating AKT1,STAT3,HSP90AA1,IL-6,and MAPK1;regulation the PI3K-AKT signaling pathway may be the critical mechanism of anti-AML effect by dandelion-mulberry leaf.

OBJECTIVES: Abdominal aortic aneurysm is a pathological condition in which the abdominal aorta is dilated beyond 3.0 cm. The surgical options include open surgical repair (OSR) and endovascular aneurysm repair (EVAR). Prediction of acute kidney injury (AKI) after OSR is helpful for decision-making during the postoperative phase. To find a more efficient method for making a prediction, this study aims to perform tests on the efficacy of different machine learning models. METHODS: Perioperative data of 80 OSR patients were retrospectively collected from January 2009 to December 2021 at Xiangya Hospital, Central South University. The vascular surgeon performed the surgical operation. Four commonly used machine learning classification models (logistic regression, linear kernel support vector machine, Gaussian kernel support vector machine, and random forest) were chosen to predict AKI. The efficacy of the models was validated by five-fold cross-validation. RESULTS: AKI was identified in 33 patients. Five-fold cross-validation showed that among the 4 classification models, random forest was the most precise model for predicting AKI, with an area under the curve of 0.90±0.12. CONCLUSIONS Machine learning models can precisely predict AKI during early stages after surgery, which allows vascular surgeons to address complications earlier and may help improve the clinical outcomes of OSR.

Surgical operation is the main treatment method for pancreatic cancer, and in clinical practice, radical surgery for pancreatic cancer is often combined with superior mesenteric-portal vein confluence pancreaticoduodenectomy to achieve R0 resection. However, severe left-sided portal hypertension (LSPH) may occur after splenic vein dissection, resulting in a series of pathological changes such as congestive splenomegaly, thrombocytopenia, backflow obstruction of splenic vein, and gastrointestinal varices, and in some cases, it can lead to fatal gastrointestinal hemorrhage and hemorrhagic shock. Therefore, in order to better manage LSPH in clinical practice, this article systematically analyzes and reviews the pathogenesis, treatment regimens, and control strategies of LSPH after combined superior mesenteric-portal vein confluence pancreaticoduodenectomy and put forward corresponding suggestions based on current studies.

Malocclusion is a worldwide dental problem that influences the affected individuals to varying degrees. Many factors contribute to the anomaly in dentition, including hereditary and environmental aspects. Dental caries, pulpal and periapical lesions, dental trauma, abnormality of development, and oral habits are most common dental diseases in children that strongly relate to malocclusion. Management of oral health in the early childhood stage is carried out in clinic work of pediatric dentistry to minimize the unwanted effect of these diseases on dentition. This article highlights these diseases and their impacts on malocclusion in sequence. Prevention, treatment, and management of these conditions are also illustrated in order to achieve successful oral health for children and adolescents, even for their adult stage.
