Objective: To investigate the impact of stroke unit (SU) on the compliance of secondary prevention in patients with stroke at 12 months after stroke. Methods: Research subjects were stroke patients who were treated in SU (n = 500) and in general ward (GW) (n =445) using a design of retrospective study. The patients in the SU group were followed up by hospital, telephone and home interviews for 12 months, and the patients in the GW group were followed up by telephone interview for 12 months. The main outcome measures were the rate of using antithrombotics, the rate of smoking cessation, and the rates of awareness of early stroke symptom and stroke risk factors of patients. Results: he rate of using antithrombotics was 92.76% in the SU group, and it was significantly higher than 51.49% in the GW group (P ＜0.01); the rate of smoking cessation, and the rates of awareness of early stroke symptom and stroke risk factors of patients were 82.33%, 91.04%, and 94.03% respectively in the SU group, and they were significantly higher than 54.75%, 6.53%, and 70.37% in the GW group(P all ＜ 0.01 ). Conclusions: SU attaches importance to the secondary stroke prevention and emphasizes standardized treatment, and the compliance of the secondary stroke prevention in patient with stroke is improved significantly.

Objective To investigate the effect and possible mechanism of microRNA-26a(miR-26a)on the syn-thesis of extracellular matrix(ECM)induced by high glucose(HG)in renal tubular epithelial cells(RTECs).Methods A model of diabetic kidney disease(DKD)was constructed by inducing RTECs with HG.MiR-26a was overexpressed in HG-induced RTECs,and RT-qPCR and Western blot were used to assess the effects of miR-26a on ECM synthesis and ferroptosis-related markers in HG-treated RTECs.Ferrostatin(Fer-1)was used to inhibit ferroptosis in the DKD model,and its impact on ECM synthesis was evaluated.RT-qPCR and Western blot were performed to measure ferroptosis-related markers,and fluorescence microscopy was used to observe the intensity of reactive oxygen species(ROS).Results Compared with the control group,the expression of miR-26a decreased in HG-treated cells,while the expression levels of ECM synthesis-related indexes fibronectin and collagen Ⅰ in-creased.After overexpressing miR-26a,the HG+miR-26a group showed a significant increase in miR-26a expres-sion and a decrease in fibronectin and collagen Ⅰ expression compared to the HG group.In terms of ferroptosis,the protein and mRNA expression of SLC7A11 and GPX4 significantly decreased,the expression of TFR-1 and AC-SL4 significantly increased,and the fluorescence intensity of ROS was significantly enhanced in the HG group com-pared with the control group.Inhibition of ferroptosis in the HG+Fer-1 group resulted in significant changes in fer-roptosis and ECM synthesis-related indicators expression levels compared to the HG group.Furthermore,re-expres-sion of miR-26a in the HG+miR-26a led to significant changes in ferroptosis-related indicators expression levels and decreased ROS fluorescence intensity compared to the HG group.Conclusions In HG-induced RTECs,miR-26a inhibits the occurrence of ferroptosis,thus reducing ECM synthesis.

Objective:To investigate the effect of artificial dermis combined with KCI negative pressure suction device in the repair of scalp defect with skull exposure after the operation of scalp malignancy.Methods:From January 2016 to June 2018, 18 patients with scalp defect and skull exposure after scalp malignant tumor surgery were treated with artificial dermis combined with KCI negative pressure suction device.Results:Eighten patients had good wound healing after the first stage of surgery, and no infection occurred. The time for artificial dermis to complete granulation was 10-14 days, with an average of 12.1 days. After the second stage of skin grafting, the skin graft had a survival rate of 100%, with uniform color and good elasticity, without obvious scar hyperplasia or contracture. The postoperative follow-up period was 6 to 2 months, all the patients healed well without tumor recurrence, with good skin elasticity and friction-resistant, and they were satisfied.Conclusions:Artificial dermis combined with KCI negative pressure suction device is an effective and simple method to repair the scalp defect with skull exposure after tumor surgery.

ObjectiveTo explore the related factors of troublemaking behaviors among patients with mental disorders induced by amphetamine-type stimulants （ATS）， and to provide references for the formulation of relevant intervention measures for ATS-induced mental disorders. MethodsA total of 105 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for ATS-induced mental disorders were included， and classified into troublemaking group and non-troublemaking group. The general demographic data and clinical data of the selected individuals were collected， and all patients were assessed using Social Support Rating Scale （SSRS）. Then univariate analysis and multivariate Logistic regression model were used to screen the related factors of troublemaking behaviors. ResultsThe scores of SSRS， objective support dimension and social support utilization dimension were significantly lower in troublemaking group than those in non-troublemaking group， with statistical differences ［（24.10±6.59） vs. （28.94±5.59）， t=3.364， P=0.001； （5.50±1.96） vs. （8.20±2.13）， t=5.183， P<0.01； （4.60±2.26） vs. （6.28±1.90）， t=3.435， P=0.001］. Multivariate Logistic regression analysis showed that male （OR=6.061， P=0.014） was a risk factor， while high social support level （OR=0.873， P=0.018） was the protective factor for troublemaking behaviors among patients with ATS-induced mental disorders. ConclusionPatients with ATS-induced mental disorders of the males and with low social support level are at high risk of troublemaking behaviors.
