Cerebral venous sinus thrombosis(CVST)is one of the significant causes of pediatric stroke.Its clinical manifestations are non-specific,including seizures,altered state of consciousness,and neurological deficits.It is usually associated with a high risk of mortality and disability.Although anticoagulation remains the first-line therapy of CVST in children,some children still experience poor prognosis.In recent years,endovascular treatment(EVT),such as mechanical thrombectomy and intrasinus thrombolysis,has emerged as a crucial therapeutic approach for CVST.This review summarized the advances in EVT for pediatric CVST,aiming to provide insights for optimizing clinical management strategies.

Objective To investigate whether the application of automated software for computed tomography angiography(CTA)and computed tomography perfusion imaging(CTP)can improve in-hospital workflow for endovascular treatment(EVT)in acute ischemic stroke patients.Methods We included patients with acute ischemic stroke who received CTA and CTP evaluation followed by EVT through the stroke emergency pathway at the Affiliated Hospital of Southwest Medical University between January 1,2020 and December 30,2022.The patients were divided into two groups:control group and artificial intelligence(Al)group based on whether automated software was used for assessment.The control group consisted of patients who underwent manual post-processing of multimodal imaging before June 2021,while the AI group was composed of patients whose imaging was processed with automated software from July 2021 onwards.The primary outcome was door-to-puncture time(DPT),and the secondary outcome was the 90-day modified Rankin Scale(mRS)score.Results A total of 312 patients were included,with 145 in the control group and 167 in the AI group.The median age of all the patients was 68 years(range:58-74 years),and 55.4％(173 patients)were male.The median National Institutes of Health Stroke Scale(NIHSS)score at presentation was 16 scores(range:12-19 scores).The median DPT was reduced from 110 min(range:80-150 min)before the use of automated software to 95 min(range:65-125 min)after its implementation(P＜0.001).However,there was no significant difference in the proportion of patients achieving functional independence(mRS score of 0-2)between the two groups(39.3％vs.41.3％,P=0.719).Conclusion The application of multimodal CT automated software improves the in-hospital workflow for acute ischemic stroke patients by reducing the time to EVT.However,the software did not significantly impact neurological functional outcomes as measured by the mRS.

Diabetic nephropathy(DN)is a common complication of diabetes and a leading cause of end-stage renal disease.Transforming growth factor-β1(TGF-β1)/SMAD signaling activation plays an important role in the onset and progression of DN.Reported findings suggest that the activation of TGF-β1(including the latent form,the active form,and the receptors)and its downstream signaling proteins(SMAD3,SMAD7,etc.)plays a critical role in DN.In addition,TGF-β1/SMAD signaling may mediate the pathogenesis and progression of DN via various microRNAs(miRNAs)and long non-coding RNAs(lncRNAs).Emerging evidence shows that TGF-β1,SMAD3,and SMAD7 are the main signaling proteins that contribute to the development of DN,and that they can be potential targets for the treatment of DN.However,recent clinical trials have shown that the anti-TGF-β1 monoclonal antibody treatment fails to effectively alleviate DN,which suggests that upstream inhibition of TGF-β1/SMAD signaling does not alleviate clinical symptoms and that this may be related to the fact that TGF-β1/SMAD has multiple biological effects.Targeted inhibition of the downstream TGF-β1 signaling(e.g.,SMAD3 and SMAD7)may be an effective approach to attenuate DN.This article discussed the current understanding of the molecular mechanisms and potential targets for the treatment and prevention of DN by focusing on TGF-β1/SMAD signaling.

Objective: To detect the expression of vascular endothelial growth factor (VEGF), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) in oral lichen planus (OLP). Methods : Thirty OLP patients and fifteen healthy subjects were enrolled in the study. Serum were collected from 15 healthy volunteers as controls. Normal tissues were collected from surgical department as immunohistochemical analysis. The levels of VEGF, ICAM-1, VCAM-1 in serum were measured by ELISA. Immunohistochemical analysis of VEGF, ICAM-1, VCAM-1 were carried out by the means of primary antibodies and anti-VEGF, anti-CD106 antigen (VCAM-1) and anti-CD54 antigen (ICAM-1). Results: ELISA results showed no expression differences for VEGF between the two groups. Whereas, the levels of ICAM-1, VCAM-1 in OLP group were significantly higher than those in control group (P < 0.05). Immunohistochemical results reveal the presence of a significant angiogenesis in OLP patients through the immunoexpression of VEGF, ICAM-1, VCAM-1 according to the percentage of stained cells (P < 0.05). Conclusion Regarding the results, it seems that high expression of VCAM-1 and ICAM-1 are related to oral lichen planus.

Objective To explore the effects of virtual teaching methods on intensive care skills teaching. Methods A total of 262 nursing students were randomly divided into two groups: intervention group ( n=131 ) and control group ( n =131 ) . The patients of two groups were received traditional experimental teaching methods and intervention group also received the virtual teaching methods. The scores of course evaluation, general self-efficacy and critical thinking ability were evaluated. Results In the intervention group, the scores of course evaluation, self-efficacy and critical thinking ability were (84. 12 ± 5. 32),(2. 72 ± 0. 35) and (293. 21 ± 5. 71) which were better than those in the control group ( t= -8. 47,-11. 66,-15. 45;P<0. 01). Conclusions The virtual teaching methods can stimulate learning interests of students and improve the scores of course evaluation, self-efficacy and critical thinking ability.

This article reports the experiment studies on treating the S-180 sarcomas of KM mice with high-intensity electric pulse and antitumor drug (cyclophosphamide). The results showed that the experimental group of electric field combined with drug has the best effect on tumor, compared with the control group. In addition, electric field can inhibit the formation of vas Capillaries and decrease the supply of nutrition for tumor cell. In conclusion, electric field has inhibited the growth of tumor.

We chose Hela cells as research object and studied the cytotoxicity generated by cyclophosphamide, an antitumor drug, after cell electroporation by the use of electromagnetic pulses. Comparison between the electroporation group and the contrast group revealed the greatly enhanced cytotoxicity of the electroporation group, indicating that under some conditions electromagnetic pulses can enhance the cytotoxicity of antitumor drugs. The results of this study provide reliable evidences and a feasible approach for clinical treatment of tumor.
