Objective:To investigate diagnostic and prognostic value of actin-binding protein ANLN in clear cell renal cell carcinoma(ccRCC)and its relationship with tumor microenvironment.Methods:Gene expression data and clinical data for ccRCC were downloaded from The Cancer Genome Atlas(TCGA).Relationship between ANLN expression and clinicopathological features was assessed by Wilcoxon rank sum test and Logistic regression.Receiver operating characteristic(ROC)curve was used to assess diagnostic value of ANLN expression in ccRCC.Kaplan-Meier and Cox regression analysis were used to investigate effect of ANLN expression on overall survival.Gene set enrichment analysis(GSEA)was used to identify signaling pathways associated with ANLN in ccRCC.Relationship between ANLN expression and immune infiltration was analyzed by ESTIMATE algorithm,tumor immune estima-tion resource(TIMER)and CIBERSORT algorithms.Relationship between ANLN and drug sensitivity was calculated using CellMiner database.Results:ANLN expression was significantly upregulated in ccRCC tissues.ANLN expression in ccRCC was correlated with clinicopathological features.ROC analysis showed that ANLN had a high diagnostic value in ccRCC.High ANLN expression was signifi-cantly associated with poor prognosis.Multivariate Cox regression analysis showed that high ANLN expression was an independent risk factor for overall survival in ccRCC patients.GSEA showed that ANLN was associated with multiple signaling pathways.In terms of immunity,ANLN was closely associated with tumor microenvironment,immune infiltration and immune checkpoint molecules in ccRCC.ANLN expression was negatively correlated with sensitivity of most antitumor drugs.Conclusion:ANLN is a potential diagnos-tic and prognostic biomarker and immunotherapeutic target for ccRCC.

Diabetes, hypertension, and dyslipidemia, collectively referred to the " Three Highs, " represent increasingly prevalent metabolic risk factors in China. Many individuals experience all three conditions concurrently, significantly heightening the risk of cardiovascular disease and mortality. Although the National Metabolic Management Center(MMC) has been established for over eight years and has its unique features, the awareness, treatment, and control rates of these diseases in China remain low, and the efficiency of community management is insufficient. According to the previous two editions of management guidelines and the most recent domestic and international diagnostic and treatment guidelines, this paper conducts an in-depth analysis of the operational experience and management strategies of the MMC. Its aim is to improve the efficiency of grassroots MMC mode management for " Three Highs" patients and ensure that patients receive more standardized management.

The latest epidemiological data suggests that the situation of adult diabetes in China is severe, and metabolic diseases have become significant chronic illnesses that have a serious impact on public health and social development. After more than six years of practice, the National Metabolic Management Center(MMC) has developed distinctive approaches to manage metabolic patients and has achieved a series of positive outcomes, continuously advancing the standardized diagnosis and treatment model. In order to further improve the efficiency, based on the first edition, the second edition guideline was composed by incorporating experience of the past six years in conjunction with the latest international and domestic guidelines.

Neovascularization plays an important role in many physiological and pathological processes, but its mechanism is still unclear. Since vascular cells are subjected to a variety of biochemical and biomechanical stimulations in vivo and live in a complex microenvironment, it is necessary to construct the vascular model in vitro and simulate the in vivo microenvironment to explore the mechanism of neovascularization. Recently, owing to the advance of micromachining and microfluidic technology, various in vitro microvascular models have emerged. Variables such as shear stress, interstitial flow and biochemical gradient of angiogenic factors have been controlled in these models, which greatly promotes the research of neovascularization. The construction, development and biomechanical design of various microvascular models are reviewed in this paper.

The tilted supine position has been evaluated to be one of the significantly effective approaches to prevent bedsore of the patients in the bedridden state. Thus, it has deeply positive influences that in view of dynamics this study explores how the position works. Based on the anatomical theories, this study formulates the human dynamic model. Furthermore, the dynamic simulation of three usual postures in tilted supine position including lying on back, lying with one knee bent and lying with the upper and lower limb on one side lifted is carried out. Therefore, the changes of the three driving forces named as chest force, waist force and thigh force in the tilted supine position can be observed. In order to verify the validity of this simulation, this study obtains the electromyogram measurements of ectopectoralis, external obliques and thigh muscles which are respectively close to the chest, waist and thigh by conducting the human force measurements experiment. The result revealed that in terms of range and trend, the experimental data and simulation's data were consistent. In conclusion, the changes of these muscles in the supine position movements are researched efficiently by both this experiment and the dynamic simulation. Besides, the result is crucially key to find the mechanism of human's tilted supine position movements.

Microfluidic technology refers to the technique of precise fluid control by manipulating submillimeter-scale fluids. In recent years, the use of microfluidic technology has realized the construction of organ-on-chips. The organ-on-chip refers to a micro-model with physiological functions, and cultivating living cells in a continuously perfused micro-chamber to simulate the physiological functions of tissues and organs. As the physiological function of the organ-on-chip has many advantages such as definite function, controllable microenvironment, rich measurement information, low chemical consumption, low cost, promising automation and high throughput, it has a huge application prospect in the field of drug development to solve the bottleneck problems in cellular and animal experiments, which has caused a great concern in the academic community. Although the organ-on-chip is still a very young research field, some microfluidic organ-on-chips have been developed and their potential applications are explored, including drug target optimization, drug screening and toxicity tests, and biomarker identification. In this review, the progress made in microfluidic organ microchips and their potential significance in clinical research were analyzed.

Objective: To investigate clinicopathological features of carcinoma showing thymus-like elements (CASTLE) in the head and neck regions. Methods: Clinicopathological data of 7 patients with CASTLE in the head and neck regions were retrospectively reviewed.Immunohistochemical staining and in situ hybridization for EBER were performed. BRAF^V600E mutation was examined by ARMS method in 6 cases. Results: There were 5 females and 2 males with age between 49 and 78 years (average of 65.6 years). All tumors were solitary nodular lesions with an infiltrative border, including 6 intrathyroid tumors and 1 extrathyroid tumor in the laryngeal pharynx.The tumors were 1.7-4.1 cm in diameter (average of 3.0 cm). Four cases demonstrated lymph node metastasis.All patients were alive without metastasis during follow-up, except one consultation case (with FNA sample) developed recurrence at the primary site. The cases showed different immunoreaction to CD5, diffuse immunoreaction with p63, CK5/6 and CD117, but negative staining for TTF1, TG and calcitonin. One case showed positive immunoreaction with Synin less than 30% tumor cells. The Ki-67 labeling index was between 3% and 90%. No BRAF^V600E mutation and EB virus infection were detected. Conclusions Extrathyroid CASTLE involving laryngeal pharynx shows the similar morphological and immunohistochemical features with intrathyroid CASTLE.Immunohistochemical markers of CD5 and CD117 are helpful in the diagnosis. Ki-67 labeling index can be high in CASTLE, especially in lymphoepithelioma type. CD5-negative CASTLE may have neuroendocrine differentiation. BRAF^V600E mutation and EB virus may not be involved in the carcinogenesis of CASTLE.
