HA / Zr O2 composite coating was prepared with optimized spraying parameters. Wear rate model of the coating was built with pin-on-disc tester basing on uniform design theory and the quadratic polynomial stepwise regression analysis method. Computational wear modeling based on the finite element method and the wear rate model was developed for artificial hip joint and the effect of joint clearance was investigated. It was proved by the experimental data that the wear rate model had a good forecasting effect within a wide range. The results of the wear simulation of artificial hip joint demonstrated that with the increasing of wear cycle,the contact stress on the contact surface of the joint decreased,while the worn area increased gradually,and the wear volume increased linearly but the growth rate of wear depth changed from fast to slow. What’s more,with the increasing of joint clearance,the wear volume of the acetabular decreased,but the largest wear depth increased.

Objective To investigate the current situation of foot risk screening of diabetic patients by community medical staffs and analyze its influencing factors. Methods The convenience sampling method was used, and a total of 78 community health service centers (stations) were selected to be included in the investigation from April 12 to 20, 2021, with at least simple diabetic foot screening tools within the jurisdiction of Changsha city. And all medical staffs meeting the inclusion criteria were included as research objects. An online cross-sectional survey was conducted using a self-designed questionnaire via the WJX platform, the general information of the study participants, the status of foot disease risk screening behavior, and its influencing factors were collected and analyzed. Independent sample t test or one-way analysis of variance were used to analyze the general data and screening behavior, and multiple linear regression was used to analyze the influencing factors of foot disease risk screening behavior in diabetic patients. Results A total of 1 954 questionnaires weredistributed, and 1 910 were effectively received with effective recovery rates of 97.75%. The score of diabetes foot risk screening behaviors of community medical staff was (54.67±11.86) points (full score was 100 points), and 1 281 patients (67.07%) always or often underwent foot risk screening. Multiple linear regression analysis showed that the influencing factors of community medical staff on foot disease risk screening behavior of diabetic patients were screening cognition degree, screening attitude, education level, participation in training, work position, charges not included in medical insurance, patient cooperation degree, hospital equipment (β=-1.870, 1.341, -1.644, 1.884, 4.303, 3.430, 0.216, 0.941, all P<0.05). Conclusions The current situation of diabetes foot screening among the community medical staff is poor, and the relevant screening awareness, attitude, training, medical security, and patient cooperation need to be further improved.

Objective To investigate the protective mechanism of PCSK9 inhibitor against oxidative low-density lipoprotein (ox-LDL) induced injury of human umbilical vein endothelial cells (HUVECs). Methods HUVECs in logarithmic growth phase were divided into Control group (normal culture group), ox-LDL group (induced by 50 mg/L oxLDL for 24 h) and PCSK9 inhibitor groups (low, medium and high dose of PCSK9 inhibitor). The low, medium and high dose of PCSK9 inhibitor groups were treated with 5, 10 and 20 µmol/L PCSK9 inhibitors for 24 h and then induced by 50 mg/L ox-LDL for 24 h. Cell activity was detected by CCK-8 assay, and cell survival rates were calculated. Transcription and secretion levels of tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6) and monocyte chemotactic protein-1 (MCP-1) in supernatant of cell culture were determined by quantitative real time polymerase chain reaction (qPCR) and enzyme-linked immunosorbent assay (ELISA). Cell apoptosis was detected by flow cytometry. The expression levels of apoptosis-related proteins (Bax, Bcl-2, Cleaved-Caspase-3) and nuclear factor-κB (NF-κB) signaling pathway related proteins were detected by Western blot assay. Results Compared with the Control group, the cell survival rate was decreased, transcriptional and secretion levels of TNF-α, IL-6, MCP-1 were increased, apoptosis rate increased, pro-apoptotic proteins (Bax and cleaved Caspase-3) up-regulated, anti-apoptotic protein Bcl-2 down- regulated and phosphorylated NF-κB (p-NF-κB) expression increased in ox-LDL group. Meanwhile, the expression of NF-κB was up-regulated in the nucleus and down regulated in cytoplasm. Compared with ox-LDL group, the survival rates were increased in medium and high dose PCSK9 inhibitor groups after treatment with PCSK9 inhibitor. The transcription and secretion levels of TNF-α, IL-6, MCP-1 and apoptosis rate decreased. The results of Western blot assay showed that the expression levels of Bax and cleaved-Caspase-3 downregulated, Bcl-2 up-regulated and p-NF-κB decreased. PCSK9 inhibitors down-regulated the expression of NF-κB in the nucleus and up-regulated the expression of NF-κB in cytoplasm of HUVECs induced by ox-LDL (P < 0.05). Conclusion PCSK9 inhibitors can inhibit ox-LDL induced inflammatory response and cell apoptosis in HUVECs and play a protective role. [ABSTRACT FROM AUTHOR]

Since the territorial spatial planning is required to merge multi- planning, unify zoning, and implement baseline regulations by land functions, compilation of spatial regulation is significant for constructing and implementing the strategies and system of spatial regulation. Even though we can unify the zoning of multi-planning through the boundary lines of spatial regulation districts, three issues must be concentrated to coordinate multi- planning regulation and reinforce the binding of territorial spatial master planning regulation to special plans and site plans. First, implement spatial regulations with human behaviors as the objects to improve constraint on negative influences. Second, merge current ordinances into territorial spatial master planning regulations. Third, enhance the guidance and constraint of baseline control model to non- developing and constructing human behaviors. The current researches have studied the definitions and objectives of the territorial spatial planning regulations through legal principles, logics, zoning and policies, and attempted to compile the strategies and systems of the territorial spatial planning regulation as well. Meanwhile, some researches have studied the influence relations among human behaviors, natural resources and territorial space. However, they lack a discussion of the compiling thinking of regulation ordinance from the perspective of human behaviors, which is an indispensable factor supporting the implementation of territorial spatial planning. This research aims at establishing a compiling thinking of the territorial spatial master planning regulation based on the perspective of human behaviors. We coordinate the zoning and regulations between territorial spatial planning regulations and regulation ordinances with human behaviors as carriers, and infer the relevant regulations of territorial spatial master plan according to the impacts caused by human behaviors to ensure the targeted implementation.
