Objective To observe the therapeutic effect of inosine on diabetic cognitive impairment (DCI) in rats and to explore its mechanism. Methods SD male rats were randomly divided into the control group, model group, and experimental group, respectively. Rats in the model group and experimental group were treated with high-fat diet combined with the intraperitoneal injection of streptozotocin and were screened out by Morris water maze experiment to obtain the DCI models, except rats in the control group. After successful modeling, rats in the experimental group were intraperitoneally injected with 100 mg/kg inosine, and rats in the control group and the model group were intraperitoneally injected with the same volume of normal saline, once a day, for 4 weeks. Morris water maze test was used to detect the cognitive ability of rats. HE staining was used to observe the morphology of hippocampal neurons. ELISA was used to detect the levels of tumor necrosis factor- α (TNF- α), interleukin (IL)-1β, IL-6, malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) in hippocampus. RT-PCR and Western blotting were used to detect the mRNA and protein expression levels of phosphatidylinositol-3-kinase (PI3K/protein kinaseB (AKT/mammalian target of rapamycin (mTOR) signaling pathway. Results Compared with the control group, the escape latency increased, and the number of crossing the platform decreased in the model group (both P<0. 05). Compared with the model group, the escape latency decreased, and the number of crossing the platform increased in the experimental group (both P<0. 05). In the model group, the hippocampal neurons were loosely arranged and irregularly shaped, and the number was significantly reduced. The hippocampal neurons of the experimental group were relatively neatly arranged and the morphology was regular, and the number increased. Compared with the control group, the levels of TNF-α, IL-1β, IL-6, and MDA in the hippocampus of the model group increased, and the levels of SOD and GSH-Px decreased (all P<0. 05). Compared with the model group, the levels of TNF-α, IL-1β, IL-6, and MDA in the hippocampus of the experimental group decreased, and the levels of SOD and GSH-Px increased (all P<0. 05). The mRNA expression levels of PI3K, AKT, and mTOR and the protein expression levels of PI3K, p-AKT, and p-mTOR were lower in the model group than in the control group (all P< 0. 05). The mRNA expression levels of PI3K, AKT, and mTOR and the protein expression levels of PI3K, p-AKT, and pmTOR in the experimental group were higher than those in the model group (all P<0. 05). Conclusions Inosine can improve the cognition and learning memory in DCI rats, thus alleviating cognitive impairment. The mechanism may be related to activating PI3K/AKT/mTOR signaling pathway and reducing inflammatory response and oxidative stress. [ABSTRACT FROM AUTHOR]

BACKGROUND: Unicompartmental knee arthroplasty has been paid more and more attention because of its advantages of fewer traumas, less blood loss, less complications, faster recovery, excellent knee function and high prosthetic survival rate. Most of the relevant reports focused on its clinical effect, but the changes in the levels of relevant inflammatory cytokines in patients after unicompartmental knee arthroplasty were rarely reported. OBJECTIVE: To investigate the effect of unicompartmental knee arthroplasty in patients with medial compartment osteoarthritis of the knee and the changes of interleukin-1, interleukin-6, and tumor necrosis factor-α levels. METHODS: A total of 30 patients with medial compartment osteoarthritis of the knee who received unicompartmental knee arthroplasty from September 2021 to March 2023 and met the inclusion criteria were selected as the study subjects. Medial angle of proximal tibia, femoral and tibial angle, pain visual analog scale score, hospital for special surgery score, knee joint range of motion, synovial fluid interleukin-1, interleukin-6, and tumor necrosis factor-α levels before and after surgery were compared and statistically analyzed. RESULTS AND CONCLUSION: (1) All 30 patients had grade I wound healing. All patients were followed up for more than 6 months after surgery. There were no complications such as prosthesis loosening and dislocation of prosthesis liner in all patients. (2) The medial proximal tibia angle and the femoral and tibial angles measured after operation were significantly improved (P < 0.05). (3) The visual analog scale score, hospital for special surgery score and range of motion measured at 1, 3, and 6 months after operation were better than those before operation (P < 0.05), and showed a gradual improvement (P < 0.05). (4) The levels of interleukin-1, interleukin-6, and tumor necrosis factor-α in synovial fluid at 3 and 6 months after operation were decreased gradually compared with those before operation (P < 0.05) and showed a gradual downward trend at each time point after operation. (5) It is indicated that unicompartmental knee arthroplasty can effectively treat medial compartment osteoarthritis of the knee, significantly relieve pain, restore knee joint function, improve knee varus deformity and lower limb strength line, and reduce the levels of inflammatory cytokines interleukin-1, interleukin-6, and tumor necrosis factor-α in joints to a certain extent.

传统基于锁相环（phase lock loop，PLL）电网跟踪型控制在电网短路比（short circuit ratio，SCR）较低或PLL带宽较高情况时，给电力系统引入负阻尼导致系统不稳定。为此，提出了一种不依赖PLL的用于区域间电网互联的新型电压源换流器（voltage source converter，VSC）虚拟同步控制。首先，构造VSC直流电压与受端系统频率间的下垂特性，当受端电网受扰后，受端换流器可为系统提供惯量支撑。其次，测量送端电压波动与直流电流波动可计算受端交流系统的频率扰动，通过模拟同步机的一次调频特性，在受端电网受扰时，送端电网可不依赖通信为受端电网提供频率支撑。与传统控制相比，在系统受扰时，利用电容储能及送端电网的调频能力为其提供频率支撑。基于PSCAD/EMTDC仿真算例验证了受端系统弱SCR场景、负荷变化场景下所提控制策略的有效性。

Exploring the perioperative application effect of a process based communication model combined with the concept of accelerated recovery after surgery (ERAS) in children with congenital spi- nal deformities (CS), and summarizing clinical experience. Methods This study is a prospective study. A to- tal of 68 pediatric patients with CS who underwent surgical treatment in our hospital from February 2022 to Feb- ruary 2023 were selected as the study subjects. They were divided into a study group (n=34) and a control group (n=34) based on management mode. The control group adopted a simple ERAS perioperative manage- ment model, while the research group adopted a procedural communication model combined with ERAS philoso- phy for perioperative intervention. Compared the time of first postoperative discharge, wound healing time, aver- age hospital stay, Chinese version of the screening chart (screen for child anxiety related emotional disorders, SCARED) Score, Chinese version of children Depression Disorder scale (depression self-rating scale for chil- dren, DSRSC) differences in scores, treatment adherence scores, number of ERAS measures completed, compli- cation rate, and pain scores. Results Among all patients, 27 were male and 41 female, mean age (8.31 ± 3.79) years, and there was no significant difference between the baseline data of the two groups (P>0.05). The postoperative time of first discharge and wound healing time in the study group were (32.76 ±5.57) h and (8.41±1.65) d, significantly earlier than the control group (62.94±7.81) h and (9.56±2.60) d (first discharge time t=18.345, P<0.001; wound healing time 12.173,P=0.033). The mean hospital day of stay in the study group was (11.12±2.14) d, significantly shorter than d (15.18±2.48) in the control group (17.221,P<0.001). Tthe two groups' admission SCARED score [Study group (20.65 ±2.01) s. Control group (20.18±2.17), 0.928, P=0.357] and DSRSC score (study group (12.59±2.12) rs, control group (12.68±2.07), 0.174,P=0.863] not significant (P greater than 0.05). However, the SCARED and DSRSC scores of the study group were (12.35 ±2.10) and (9.88±1.70), significant lower (18.59± 1.79) and (11.09±1.85) points than the control group, The differences were statistically significant (P was less than 0.05); [Study group (13.76 ±1.44) ts. control group (9.32 ± 1.84), 11. 102, P<0.001], number of items completed by ERAS measures [Study group (15.91 ±1.49) rs. Control group (13.35 ± 1.54),16.987,P<0.001],complication rate (5.88% of the study group rs. 23.53 of the control group, x = 4.221,P=0.040) and pain score [study group (2.91±0.87) zs. control group (3.76 ± 1.39),1 = 3.031,P=0.003] were all superior over the control group. Conclusions The application of a procedural communication model combined with ERAS concept in perioperative management of CS patients has a better effect, which can effectively improve the postoperative rehabilitation level and treatment compliance of patients, reduce their psychological stress level, and reduce the incidence of complications.

To investigate the effects of sulfate on the properties of cementitious materials, mortar specimens with water-cement ratio of 0. 5 and 0. 35 were designed and subjected to full immersion tests to study the effects of different sulfate concentrations on the water transport properties, mechanical properties and sulfate ion transport properties of cementitious materials at different depths. The results show that the water absorption of cementitious materials after sulfate attack increases with the age of attack. The flexural and compressive strength of cementitious materials shows a trend of increasing and then decreasing with the age of sulfate attack and the concentration of attack solution. The concentration of sulfate ions increases with the increase of sulfate concentration and the concentration of sulfate ions at the same depth. The sulfate attack of cementitious materials produce swelling products to fill the internal pores and increase the mechanical properties of the specimens. [ABSTRACT FROM AUTHOR]

AVP in intelligent transportation systems is an excellent solution for improving fuel efficiency and driving safety. Based on Internet of Things and 5G communication technology, autonomous vehicle platoons are susceptible to various attacks during the process of intelligent teaming and behavior communication, leading to safety accidents. To this end, an attribute-based revocable traceable access control scheme is proposed in combination with edge computing technology. Firstly, fine-grained access control is achieved using attribute-based encryption. Secondly, dynamic updating of the platoon key is implemented using CRT, allowing for the message's revocable storage and reducing the computational overhead on the vehicle-side through the assistance of roadside infrastructure. Furthermore, an anonymous user and traceability of malicious vehicles are achieved using an elliptic curve encryption mechanism. Finally, through security analysis and simulation experiments, it is shown that the scheme is feasible in terms of security and efficiency. [ABSTRACT FROM AUTHOR]

The simple parallel computing or single heterogeneous platform can no longer meet the requirements of signal processing and task scheduling with large computation and high complexity, so heterogeneous multi platform system has become the development trend of signal processing and task scheduling. In view of improving the throughput of the platform, utilization rate of the processor and perception of the task, this study investigates the signal processing model of heterogeneous multi-platform, and the scheduling tasks and hardware and software resources are modeled by directed acyclic graph. Based on the proposed scheduling algorithms, the task scheduling is summarized and compared. It is found that the hybrid scheduling algorithm based on task perception can meet the platform scheduling requirements well. It is a trend of future research to use mixed scheduling algorithm based on task perception to solve task scheduling in signal processing. [ABSTRACT FROM AUTHOR]
