Objective To observe the short-term efficacy of domestic RECO stent used in endovascular treatment of acute posterior circulation infarction, and to analyze the factors affecting the prognosis of patients. Methods The clinical data of 148 patients with acute posterior circulatory infarction who used domestic RECO stents and Solitaire stents for endovascular treatment admitted to The First Department of Neurosurgery, Tieling Central Hospital from December 2018 to October 2020 were analyzed retrospectively. The recanalization of the blood vessels in patients with two different thrombectomy stents were observed, and the mRS score of patients after 3 months were counted. After 3 months, patients with mRS scores of 0-2 were classified as the good prognosis group, and patients with mRS scores of 3-6 were classified as the poor prognosis group. The general clinical data of the two groups of patients with good and poor prognosis using domestic RECO stents were compared. The relevant factors that may affect the prognosis of patients were analyzed. And the clinical effect of using other stents in the same period for emergency postertor-circulation embolectomy were compared. Results Among 98 patients with acute posteriorcirculatory infarction using domestic RECO embolization stent, 90 were recanalized and 8 were not recanalized. After 3 months, the mRS score showed good prognosis group was 60 cases, and poor prognosis group was 38 cases. There were 50 patients with acute posterior circulation infarction, 45 patients with recanalization, 5 patients without recanalization, 3 patients with postoperative death, 31 patients with good prognosis and 19 patients with poor prognosis after 3 months of mRS score. There was no significant difference in the short-term efficacy of domestic RECO stent used in the treatment of acute posterior circulation infarction compared with Solitaire stent (P ＞ 0. 05). After analyzing the related factors that may lead to poor prognosis of patients who use domestic RECO stents to remove thrombi,it is concluded that PC-ASPECTS score at admission,collateral compensation,NIHSS score at admission,time from onset to femoral artery puncture,times of thrombus removal,and whether diabetes are associated with the related factors that affect the prognosis of patients. Conclusions The domestic RECO stent used in the endovascular treatment of acute posterior circulation infarction has a significant short-term effect. The higher the patient's PC-ASPECTS score,the better the collateral compensation,the lower the NIHSS score at admission,and the shorter the time from onset to femoral artery puncture. The near-term prognosis is better. [ABSTRACT FROM AUTHOR]

The discordant position of theoretical engagement point and actual engagement point was due to the tooth profile deviation of cycloid gear. Aiming at this problem, a method to determine the real engagement point of cycloid-pin pair with tooth profile deviation was proposed. Firstly, the cycloid tooth surface was sampled by the gear measuring center, and the digital representation of the tooth profile was obtained based on cubic B-spline curve reconstruction. Then, based on the cycloid-pin pair transmission principle and gear train conversion principle, it was transformed into fixed axle gear train and the real contact analysis model of cycloid-pin pair was established. A method to solve the model was proposed and the results were calculated by MATLAB programming, and then the contact impressions were obtained. Finally, the meshing point positions and imprints of cycloid-pin pair obtained from theoretical standard tooth profile and actual tooth profile were compared and analyzed. The research results show that, the cycloid rotation angle at the real engagement point of cycloid-pin pair is 0.3° different from that at the theoretical engagement point, the tooth profile deviation has an effect on the meshing point position of cycloid-pin pair, which provides support for the research of the actual meshing characteristics of cycloid-pin pair.

Rejection has constantly been an unresolved challenge in the field of organ transplantation. The research on the mechanism of rejection plays a significant role in improving the efficacy of organ transplantation and enhancing the survival rate of graft. The innate and specific immune responses of the human body jointly participate in the graft rejection, leading to graft injury. In recent years, multiple researchers have conducted in-depth studies on the mechanism underlying the role of microRNA (miR) in regulating rejection. Among them, miR-155 has been widely considered as a key factor involved in immune regulation. The expression level and functional status of miR-155 may be intimately associated with the occurrence of rejection, which may become a new target for overcoming rejection. In this article, relevant studies on the role of miR-155 in regulating key immune cells in innate and specific immune responses were reviewed, aiming to provide novel ideas for the development of new immunosuppressants and rejection therapy.

Objective To assess the relationship between diabetes mellitus and risk of anterior circulation aneurysm rupture. Methods The clinical data of 680 patients with intracranial aneurysms (IA) were analyzed retrospectively. The correlation between diabetes and the risk of rupture of IA was further judged by univariate and multivariate analysis. Results In univariate analysis, hypertension (P=0.001), family history of IAs (P = 0.007), history of subarachnoid hemorrhage (P = 0.039), irregularity (P = 0.001), size≥8 mm (P = 0.006) and diabetes (P=0.005) might have statistical differences. After excluding the influence of confounding factors, the results of multivariate analysis showed that the proportion of diabetes was statistically different between the ruptured group and the unruptured group (OR = 1.68,95% CI: 1. 160~2.470, P = 0.025). Conclusion Diabetes may increase the risk of rupture of anterior IA, which may be related to the metabolic disorder related angiopathy caused by diabetes and the mutation of diabetes related genes (SLC2A9, TOX), etc. [ABSTRACT FROM AUTHOR]

Representation learning of a user-item interaction network becomes an effective recommendation method. Most of the existing methods regard the interaction network as a static homogeneous network, ignoring the impact of interaction timing and node heterogeneity. In response to this problem, this paper proposed a recommendation method based on dynamic bipartite network representation learning. Firstly, the method constructed a time-series weighted bipartite network, and then respectively mapped user nodes and item nodes to different vector spaces to preserve the heterogeneity of the network, and aggregated the first-order and high-order neighbor information for center nodes with graph convolution. Finally it used a multi-layer perceptron to learn the nonlinear relationship between the two types of node embeddings and performed top-N recommendation. Experimental results on Amazon and Taobao datasets show that the proposed method is significantly superior than the related methods based on static or heterogeneous network representation learning in HR and NDCG indicators.
