Objective To study the target organ damage in patients of hypertension with metabolic disorder. Methods 1033 patients were divided into five groups: hypertension without complications(102 cases), hypertension with dyslipidemia (117 cases), hypertension with abdominal obesity(119 cases), hypertension with type 2 diabetes mellitus(135 cases), hypertension with metabolic syndrome (560 cases). The structure and the function of heart and blood vessel were examined by color Doppler. Urinary microalbuminuria was determined. Results (1)Only 9.9% patients of hypertension were without metabolic disorder, 90.1% hypertensives complicated with the metabolic disorder; (2)Compared with hypertension with dyslipidemia, hypertension with type 2 diabetes mellitus (P90%) complicated with the metabolic disturbance. Hypertension complicated with abdominal obesity accentuate left ventricular hypertrophy. Hypertension with diabetes mellitus and metabolic syndrome accentuated the vascular and renal lesion.

Objective To investigate the change of the percentage of Th17 cells and cytokine among hepatocellular carcinoma (HCC) tissues and para-carcinoma tissue and the liver tissue of hepatic hemangio-ma, and to explore its clinical significance. Methods To choose 26 of hepatocellular carcinoma patients between November 2014 and December 2016 and also include 11 cases of hepatic hemangioma as control group. The percentage of Th17cells in HCC tissue and para-carcinoma tissue and the liver tissue of hepatic hemangioma was evaluated by flow cytometric; The levels of IL-6 and IL-17 in HCC tissues, para-carcinoma tissue and the liver tissue of hepatic hemangioma were detected by RT-PCR. Results The ratio of Th17 cells to CD4 cells in peripheral blood of HCC was significantly higher than that in control group (4. 07% ± 0. 68% vs. 1. 39% ± 0. 41% ), P＜0. 05. The ratio of Th17 cells to CD4 cells in patients with hepatocellular carcinoma was significantly higher than that in paracancerous tissues and liver tissues of hepatic hemangioma (4. 76% ± 0. 75% vs. 2. 30% ± 0. 26% vs. 0. 77% ± 0. 31% , P＜0. 05). Multivariate linear stepwise regression analysis of the changes of Th17 cells in patients with HCC and their correlation with clinical parameters showed that Th17 lymphocytes in peripheral blood of patients with HCC were closely related to TNM staging(YTh17 =2. 647 +0. 687TNM. It’s indicated that the level of IL-6 and IL-17 in liver cancer tissues was significantly higher than that of the liver hemangioma in the control group through ELISA ( P＜0. 05). The proportion of peripheral blood Th17 cells to CD4 cells is different in different TNM stages(stage I＜stage II ＜stage III ～IV, the difference was statistically significant. RT-PCR analysis showed that the expression of IL-17, IL-6mRNA in hepatocellular carcinoma was significantly higher than that in adjacent tissues and hepatic hemangioma liver tissue (all P＜0. 05). Conclusion The increased proportion of Th17 cells and the increased levels of cytokines IL-6 and IL-17 may be closely correlated with occurrence and development of hepatocellular carcinoma. It can be an important target of anti-tumor therapy.

BACKGROUND:Osteoarthritis is a common chronic inflammation of joints caused by degenerative changes of articular cartilage.More and more studies have shown that mechanical stress is closely related to the development of osteoarthritis.The Hippo pathway is not only involved in the development of tissue cells,but also an effecting factor of mechanical stress,which is involved in the regulation of bone metabolism and cartilage metabolism. OBJECTIVE:Regulation of the Hippo pathway may become one of the new targets for intervention in osteoarthritis.Therefore,this paper reviewed the research on the effect of mechanical stress regulation of the Hippo pathway on osteoarthritis to provide ideas for the pathogenesis of osteoarthritis and provide a new theoretical basis for the treatment of osteoarthritis. METHODS:PubMed,Web of Science,Embase,CNKI,VIP,and WanFang databases were used for a literature search for articles published from inception to 2023 concerning the influence of mechanical stress on osteoarthritis and mechanical stress,Hippo pathway,and osteoarthritis.A total of 75 articles were finally reviewed. RESULTS AND CONCLUSION:(1)Different mechanical stresses may play different roles in cell proliferation,apoptosis and differentiation,osteoarthritis inflammation,and vascular homeostasis in osteoarthritis.(2)Hard extracellular matrix,low cell density,medium shear force,medium tensile force,and compression force can achieve cell proliferation,osteogenic differentiation,and vascular homeostasis,and inhibit inflammatory response by activating YAP/TAZ.(3)Soft extracellular matrix,high cell density,excessive shear force,excessive tensile force,and compressive force inhibit cell proliferation,enhance cartilage differentiation,disrupt vascular homeostasis,and promote inflammation through inactivation of YAP/TAZ,thus promoting the process of osteoarthritis.

Bone homeostasis is based on the dynamic balance of bone formation and bone resorption. An imbalance in bone homeostasis is a major contributor to many skeletal diseases, including osteoporosis. Changes in the composition and diversity of the gut microbiota (GM) are supposed to have a significant impact on bone homeostasis and are closely correlated with changes in bone mass and bone microarchitecture. The "gut-immune" axis, which is formed by the interaction between the host intestinal immune system and GM, is essential for maintaining bone homeostasis, as well as regulating the body's immunological response and maintaining immune homeostasis throughout the intestine and body. The article reviews recent advances in the study of GM, the immune system, and their synergistic impact on bone homeostasis.

【Objective】 To analyze the literature on the relationship between gut microbiota and bone metabolism, identify the current research hotspots and difficulties, and provide research ideas and directions for the clinical prevention and treatment of bone metabolism related diseases. 【Methods】 Based on the Citespace literature visualization analysis software, the co-occurrence and cluster analysis of keywords and other information of the included 394 literatures were performed, and the visual map was drawn. 【Results】 Among the included literatures, the keywords such as inflammatory bowel disease, T cells, dendritic cells, short-chain fatty acids, and chronic kidney disease appeared with high frequency. The cluster of intestinal alkaline phosphatase, metabolic osteoarthritis, dendritic cells, and signaling pathway was the current research hotspot. Recent years have witnessed a rapid increase in published articles in this field, with the United States as the leading origin. 【Conclusion】 The mechanism by which gut microbiota interferes with the immune system and regulates bone metabolism to maintain bone homeostasis is still the core of current research.
