The dysfunction of qi, blood, and fluid underlies the pathology of diabetes mellitus. The symptoms, signs, and physical and chemical indexes of diabetes mellitus patients reflect the duration, degree, primary and secondary pathological state of the abnormal metabolism of qi, blood, and fluid. It is necessary to construct a three-dimensional syndrome differentiation system of diabetes mellitus based on spatial and temporal dimensions. According to the four stages of depression, heat, deficiency, and damage, the location of the disease can be locked into qi, ying, and blood levels. The process reflects the pathological trend of the abnormal metabolism of qi, blood, and fluid: qi depression (prodromal stage: asymptomatic metabolic disorder/early stage of qi level) → qi heat (initial stage: index stage/late stage of qi level) → deficiency of both qi and yin (middle stage: symptom stage of three more and one less/stage of ying level) → damage of zang-fu viscera and meridians (late stage: complication stage/stage of blood level). According to the time process, the treatment principles are proposed as follows: during the early stage of qi level, treatment should focus on strengthening the spleen to regulate qi flow, to prevent the accumulation of glucose; during the late stage of qi level, treatment should focus on clearing heat and resolving turbidity, to remove the stagnated heat caused by glucose; during the stage of ying level, treatment should focus on benefiting qi and nourishing yin, to improve the symptoms about deficiency of both qi and yin; during the stage of blood level, treatment should focus on promoting blood circulation and removing blood stasis, to remove the complication. According to the etiology and pathogenesis of diabetes mellitus, the sequential treatment strategy is thus proposed, which is strengthening the spleen to regulate qi flow, clearing heat and resolving turbidity, benefiting qi and nourishing yin, and promoting blood circulation and removing blood stasis. The compound prescriptions such as Houpo Sanwu Decoction, Baihu Jia Renshen Decoction, Danggui Liuhuang Decoction, and Taohong Siwu Decoction are used with modification in the stage-based treatment.

The occurrence of diabetes mellitus （DM） is closely related to insulin resistance and islet β cell dysfunction. Modern studies have found that macrophages are widely present in the liver，fat，skeletal muscle，islets， and other tissues and organs. Macrophage M1/M2 polarization plays an important role in the occurrence and development of diabetes mellitus and its related complications by intervening in inflammatory response，improving insulin resistance，and promoting tissue repair. Most of the traditional Chinese medicines that regulate the activation and polarization of macrophages are Qi-replenishing and Yin-nourishing，heat-clearing， and detoxicating medicinal，which are consistent with the etiology and pathogenesis of diabetes and its related complications. Therefore，by summarizing the mechanisms between macrophage activation，polarization， and insulin resistance in various tissues，this paper reviewed traditional Chinese medicine and its effective components and compounds in improving diabetes mellitus and its related complications through multi-channel regulation of macrophage polarization and regulation of M1/M2 ratio，providing references for the future treatment of DM and its related complications with traditional Chinese medicine.

This paper summarizes the clinical experience in applying jiao （角） medicine to treat diabetes mellitus from the perspective of qi， blood， and fluids. It is believed that impaired spleen transportation and transformation is the key pathomechanism of diabetes， leading to metabolic disturbances in qi， blood， and fluids， and resulting in a sequential pathological progression of "qi → thick fluids → thin fluids → blood". At the qi level， the disease is mainly characterized by spleen qi deficiency and stagnation， and is commonly treated with Hongshen （Panax Ginseng）， Huangqi （Astragalus Mongholicus）， and Baizhu （Atractylodes Macrocephala） to tonify the spleen and regulate qi. At the thick fluids level， the condition manifests as abdominal distension， internal heat， and turbid pathogens， requiring Zexie （Alisma Orientale）， Huanglian （Coptis Chinensis）， and Dahuang （Rheum Palmatum） to clear the spleen and drain turbidity. At the thin fluids level， with qi and yin deficiency and predominant yin damage， Gegen （Pueraria Lobata）， Wuweizi （Schisandra Chinensis）， and Maidong （Ophiopogon Japonicus） are used to nourish yin and generate fluids. At the blood level， where vascular damage is predominant， Shuizhifen （Whitmania Pigra Powder）， Danshen （Salvia Miltiorrhiza）， and Sanqifen （Panax Notoginseng Powder） are applied to activate blood circulation， resolve stasis， and unblock the channels. Clinicians may flexibly select appropriate jiao medicine based on the specific pathological layer affected in each patient.

ObjectiveThrough multimodal research methods including medication rule mining， network pharmacology， molecular docking and dynamics simulation， and in vivo animal experiments， this study aims to speculate and verify the core composition （Ginseng Radix et Rhizoma Rubra-Salviae Miltiorrhizae Radix et Rhizoma-Notoginseng Radix et Rhizoma） and efficacy （Qi-invigorating and blood-activating） of the drug combination in Yitangkang Compound for improving diabetic cardiomyopathy （DCM）， investigate the interaction relationship and binding strength between core active ingredients of the drug combination and key signaling pathway targets， and further explore the mechanism by which the Qi-invigorating and blood-activating drug combination regulates the calcium signaling pathway to improve cardiac function in DCM rats. MethodsThe Ancient and Modern Medical Cases Cloud Platform was used to construct a DCM prescription database， and the "Analysis Method" module of the platform was applied to mine and summarize medication rules， thereby determining the core composition of the Qi-invigorating and blood-activating drug combination in Yitangkang. Drug-active ingredient-signaling pathway-core target-disease analysis and visualization were conducted by combining network pharmacology with the Traditional Chinese Medicine System Pharmacology Platform （TCMSP） database， SwissTargetPrediction platform， GeneCards database， MetaScape database， CytoScape software， etc. Then， molecular docking was performed via the CB-Dock2 platform， and molecular dynamics simulation of the high-binding-strength docking complexes was carried out by Gromacs software. Finally， in vivo animal experiments were carried out. Twenty-eight Sprague Dawley （SD） rats meeting the research criteria were divided into a normal group， a model group， a drug combination group （3.3 g·kg^-1）， and a Yitangkang group （20 g·kg^-1）. A type 2 diabetes mellitus （T2DM） rat model was established by high-fat diet feeding combined with intraperitoneal injection of streptozotocin （STZ）， followed by continuous feeding for eight weeks until the DCM model was successfully established. During this period， the traditional Chinese medicine （TCM） compound and drug combination were administered for prevention and treatment intervention. Meanwhile， changes in blood glucose， body weight， and heart index of each group were monitored. Cardiac function was assessed by echocardiography， and electrophysiological signals were detected by an electrocardiogram. The heart tissue was observed for pathological changes by hematoxylin-eosin （HE） and Masson staining， and the expression of L-type calcium channel （CACNA1C）， calmodulin （CALM1）， calcium/calmodulin-dependent protein kinase Ⅱδ （CAMK2D）， and neuronal nitric oxide synthase （NOS1） proteins in the calcium signaling pathway of myocardial tissue was detected by Western blot. ResultsIn 62 DCM prescriptions， Ginseng Radix et Rhizoma Rubra， Salviae Miltiorrhizae Radix et Rhizoma， and Notoginseng Radix et Rhizoma were used most frequently. Their meridian tropism mainly involved the spleen， heart， and lung， and their sweet and warm properties were prominent. The drugs for tonifying or blood-activating and stasis-resolving ranked top. In association rule analysis， （Ginseng Radix et Rhizoma Rubra， Salviae Miltiorrhizae Radix et Rhizoma）-Notoginseng Radix et Rhizoma had the highest lift. Network pharmacology obtained 75 active ingredients of the drug combination， 714 drug combination action targets， 2 702 disease targets， and 286 intersection targets. Protein-protein interaction （PPI） network predicted nine interaction component-targets （nine active ingredients and four calcium signaling pathway target genes）. Molecular docking showed the four complexes with the lowest binding energy were 2f3z-ginsenoside Re， 1cll-quercetin， 9blh-（6S）-6-（hydroxymethyl）-1，6-dimethyl-8，9-dihydro-7H-naphtho［8，7-g］benzofuran-10，11-dione， and 5vv0-miltionone Ⅱ. Dynamics simulation showed the CALM1-quercetin complex had the strongest binding affinity. The animal experiment results revealed that compared with the normal group， the model group showed significant changes in blood glucose， body weight， myocardial tissue morphology， heart index， cardiac function， electrophysiological indexes， and the expression levels of CACNA1C， CALM1， CAMK2D， and NOS1 proteins （P<0.05， P<0.01）. Compared with the model group， the Yitangkang group had a certain improvement effect on the above indexes （P<0.05， P<0.01）. Compared with the Yitangkang group， the drug combination group showed no significant difference in improving myocardial tissue morphology， heart index， cardiac function， electrophysiological indexes， and the expression of CACNA1C， CALM1， CAMK2D， and NOS1 proteins， except for blood glucose and body weight. ConclusionGinseng Radix et Rhizoma Rubra， Salviae Miltiorrhizae Radix et Rhizoma， and Notoginseng Radix et Rhizoma are the core Qi-invigorating and blood-activating drug combination in Yitangkang Compound. They have a good preventive and therapeutic effect on STZ-induced DCM in rats， and their mechanism of action may be related to the regulation of the calcium signaling pathway.

Three-dimensional printed patient-specific instrumentation (3D-PSI) provides a precise and individualized treatment solution for unicompartmental knee arthroplasty (UKA). Currently, this technology is being applied in clinical practice and has demonstrated certain potential. Compared to conventional instrumentation (CI), 3D-PSI offers a broader range of indications, higher-quality preoperative planning, shorter surgical time, a smoother learning curve, more precise osteotomy and prosthesis placement, and better postoperative functional recovery. However, it still has limitations in the rotational alignment of the tibial component. Additionally, the higher cost for patients and increased hospital equipment investment make it less beneficial for surgeons already proficient in CI techniques. Further reliable evidence is needed to compare 3D-PSI with computer navigation and robotic technologies. This review summarizes the advantages and limitations of 3D-PSI assisted UKA and compares 3D-PSI with different auxiliary technologies.

Objective To investigate the association between single nucleotide polymorphisms(SNP)rs57095329 and rs6864584 of miR-146a gene and cervical intraepithelial neoplasia(CIN).Methods A total of 96 patients diagnosed with CIN were randomly collected as the CIN group,and 225 healthy individuals examined during the same period were selected as the control group using SPSS software.Genotyping of the above SNP loci was performed using the TaqMan probe method,and their correlation with CIN was analyzed.Results The allele and genotype distribution of rs57095329 showed a statistically significant differences compared to the control group,with the frequency of the allele A in the CIN group significantly lower than that in the control group(P<0.001;OR=0.48,95%CI:0.32～0.70).In the dominant model,individuals carrying the G allele(A/G-G/G)had a significantly increased risk of CIN(P<0.001;OR=2.67,95%CI:1.64～4.37).In contrast,no correlation was found between the rs6864584 and the risk of CIN.Conclusion The A allele of the miR-146a gene at the rs57095329 locus may be a protective factor for CIN.

Objective To analyze the single nucleotide polymorphism (SNP) and copy number variation (CNV) of cardiac myxoma to find the SNP sites and CNV events that may play important roles in the occurrence of tumors. Methods The patients with myxoma admitted to our hospital from 2015 to 2019 were randomly selected. The SNP analysis and the CNV test in gene level were performed through whole exome sequencing (WES). The samples were divided into two groups according to the mean size of the tumor: a diameter≤5.7 cm group and a diameter>5.7 cm group. The analysis results were compared between the two groups. Results A total of 14 patients were enrolled, including 8 females and 6 males with a mean age of 61.4 (41-79) years. Thirty-seven cancer-genes with SNP were detected, among which 18 mutated sites had a mutation rate of>10%; and TP53, EP300 and CREBBP played a core binding role in protein-protein interaction-network. The GO enrichment results showed significant differences in the regulation of cell secretion of the mutated genes, and the KEGG enrichment results showed significant differences in the PI3K-AKT and JAK-STAT signaling pathways in the occurrence of myxoma. In addition, 17 new mutation sites of tumor genes with high mutation effect were found in SNP detection. The WES results of 14 samples showed that the CNV events were detected in 120 tumor genes of the samples, 10 of which were included in two tumor databases. The GO enrichment results showed significant differences in the tube development and regulation of cell proliferation, and the KEGG enrichment results showed significant differences in the comprehensive tumor signaling pathway. Statistical differences of ERCC6L and INTS6L in CNV test were found (P=0.030). Conclusion There may be multiple tumor gene site mutations in the process of tumor generation, among which there are multiple core tumor genes such as TP53, EP300 and CREBBP, regulating tumor cells through PI3K-AKT and JAK-STAT signaling pathways and playing an important role in tumor generation. The CNV of ERCC6L and INTS6L genes may be related to tumor growth.

The theory of "linkage between spleen and small intestine" has been put forward by doctors as early as the Ming dynasty. In traditional Chinese medicine， the spleen and small intestine cooperate and work together physiologically， and they are also closely related and interact with each other pathologically. The spleen governs transportation and transformation， which involves the function of the small intestine in transforming water and grain. The small intestine， governing the receiving and transformation of substances， depends on the normal transportation of the spleen. At the same time， it provides guarantee for the spleen to transform Qi and generate blood as well as ascend lucidity and descend turbidity. The dysfunction of spleen in transportation is closely related to the dysfunction of small intestine. The stability of intestinal microecology necessitates the normal functioning of the spleen. When the original balance of intestinal flora is disturbed， the spleen functioning will be affected. This study explored the pathogenesis and treatment of diabetes based on the physiological functions of the spleen and small intestine and the Western medicine targets of "nutrients-intestinal flora". According to modern medicine， nutrients are essential to maintain the normal physiological activities of the human body. Proper intake of nutrients can affect the absorption and metabolism of the human body for nutrients by regulating the composition and function of intestinal flora， so as to prevent the occurrence of diabetes. The imbalance of intestinal flora which harbors rich microorganisms may lead to the disturbance of energy metabolism and the dysfunction of the immune system， eventually leading to diabetes. As a metabolic disease， diabetes is closely related to the imbalance of intestinal flora and nutrient intake. Based on the theory of "linkage between spleen and small intestine"， this paper discusses the relationship between spleen and small intestine. Furthermore， this paper discusses the correlation between "spleen-small intestine" and "nutrients-intestinal flora" by reviewing the latest progress in modern medicine and clinical research， aiming to provide a theoretical basis and new ideas for the clinical prevention and treatment of type 2 diabetes mellitus.

By analysing the conceptual connotations of phenotype and traditional Chinese medicine （TCM） symptoms， the relationship between TCM symptoms， phenotypes and diseases is explained. It is believed that phenotypes and TCM syndromes have certain similarities， both of which elaborate the physiological and pathological mechanisms of the human body through external manifestations， and have the temporal and spatial characteristics of both phases and wholeness， as well as focusing on the connection between the innate and the acquired. Summarising the current status of the application of phenomics technology in the studies of TCM syndromes， it is concluded that the study of the intrinsic biological mechanisms of TCM syndromes with the help of phenomics technology has achieved certain results， but there are still problems such as difficulties in matching between traditional Chinese medicine syndromes and phenotypes， the incompleteness of the existing disease phenotype system， and the inconsistency of the understanding about "syndromes". It is proposed that in the future， large-scale clinical databases could be used to collect a wide range of TCM syndromes and phenotypes that are closely related to specific diseases. The phenomics technology could make preliminary correspondence and identification between a single syndrome and the corresponding phenotype， and then further carry out a more accurate phenotypic detection of the composite syndromes， and finally realise the standardization and intelligence of the diagnosis of TCM syndromes with the help of the artificial intelligence technology. By elaborating the modern scientific connotation of TCM syndromes from the perspective of phenotypes， we can provide scientific basis for the determination of TCM syndromes and the clarification of modern biomarkers of syndromes， as well as ideas for the modernisation research of TCM syndromes.
