Academia-industry collaboration is defined as the cooperation between both sides,utilizing the capitals and pathways of the industrial side as well as the faculties and facilities of the academic side to push the products to the market with cost minimization as well as profit or utility maximization.All the group members share the results to attain the double win.The six key steps to establish this collaboration include creating the cooperation platform,signing related agreements,constructing related hard and software,setting a company for operation,performing experiment,licensing,patent or technique transfer,products marketing as well as sharing profits.Several issues should be known while this collaboration established in the biomedical field,especially about the ethics of human studies.The influencing factors of its effectiveness would be analyzed in the present paper.

Objective: To explore the hemorrhagic transformation(HT) and its effect on prognosis in patients with acute ischemic stroke(AIS) after mechanical thrombectomy(MT). Methods: A total of 114 patients with AIS received MT were enrolled. The modified Rankin Scale was used to evaluate the clinical outcome at 90 days of onset(0-2 points were good prognosis; 3-6 points were poor prognosis). The patients were divided into HT group(n=25) and non-HT group(n=89) according to their HT conditions. Binomial Logistic regression analysis was performed to determine the vascular risk factors of HT after MT and the effect of HT on prognosis. Results: Among 114 patients, there were 25 cases of HT and 89 cases of non HT. The proportion of patients with diabetes in HT group was significantly higher than that in non-HT group. The NIHSS score of HT group at discharge was significantly higher than that in non-HT group. The proportion with good prognosis at 90 days in HT group was significantly lower than that in non-HT group(allP<0.05). Binomial Logistic regression analysis showed that diabetes, high levels of cholesterol and smoking were the major vascular risk factors for HT after thrombectomy(allP<0.05). HT was an important factor affecting the poor prognosis after arterial thrombectomy(P=0.026). Conclusion Diabetes, high levels of cholesterol and smoking are the main risk factors of HT after MT for AIS. HT is an independent risk factor for poor prognosis after MT.
