With the rapid development of the Internet and mobile information technology, the state has made it clear that "Internet¬+" education has become an important development project for national education. Information technology education is also playing an increasingly important role in the development of students, and online and offline hybrid teaching is a teaching mode that is very suitable for information technology. Online and offline blended teaching is a new teaching model that has emerged in the mobile internet era, and is a combination of online learning and the advantages of traditional teaching. However, there are still problems with online and offline blended teaching such as uncertainty in the use of educational resources, so a more appropriate teaching process system needs to be tapped to achieve better teaching results.

Background Racial disparities in endometrial cancer have been reported in the United States, but trends and the underlying causes are not well understood. We aimed to examine the trends and contributing factors in racial disparities for causes of death among endometrial cancer patients. Method In this population-based cohort study, we identified 139 473 women diagnosed with first, primary endometrial cancer between 1992 to 2018 from the Surveillance, Epidemiology, and End Results Program. We used the "Fine and Gray" method to calculate the cumulative incidence of all-cause and specific-cause death. We used proportional subdistribution hazard (PSH) and cause-specific hazard (CSH) models to quantify the relative risk of Black–White disparities. We performed a mediation analysis to assess the contribution of potential factors to disparities. Results The cumulative incidence of all-cause death decreased in endometrial cancer patients, with estimates at 5 years of 26.72% in 1992-1996 and 22.59% in 2007-2011. Compared with White patients, Black patients persistently had an increased risk of death due to endometrial cancer (PSH hazard ratio [HR] = 2.05, 95% confidence interval [CI] = 1.90 to 2.22; CSH HR = 2.19, 95% CI = 2.00 to 2.40) and causes other than endometrial cancer (PSH HR = 1.23, 95% CI = 1.10 to 1.37; CSH HR = 1.46, 95% CI = 1.31 to 1.63). Grade, histological subtype, surgery utilization, and stage at diagnosis explained 24.4%, 20.1%, 18.4%, and 16.6% of the Black-White disparity in all-cause death, respectively. Conclusions Although the cumulative incidence of all-cause death decreased, the Black–White gaps persisted in patients with endometrial cancer. Grade and histological subtype had the greatest influence. More efforts are needed to address the disparities. [ABSTRACT FROM AUTHOR]

Abstract: Intelligent data searching of network is a hotspot research aspect currently. When the user puts forward a request that the system should provide a right answer from the vast data online, it is a really hard to resolve such problem. Our research work on core algorithm for intelligent searching system is right way for answer those questions. [Copyright &y& Elsevier]

With the change of the spectrum of disease, the incidence and mortality of non-small cell lung cancer (NSCLC) has been high in global scale, since surgical intervention was applied to treat lung cancer, its status is increasing day by day, at present comprehensive treatment leaded by surgery has become the preferred scheme for NSCLC, there are many different kinds of surgical approaches and operation methods of disease, and the new technologies appear constantly, the paper aim to summarize the research progress of different operationmethods and surgical approach. With the development of software and hardware technology and the concept of minimally invasive thoracoscopic surgery was received by more people, minimally invasive thoracoscopic surgery has brought more benifit than traditional thoracotomy for lung cancer patients, minimally invasive thoracoscopic surgery reserve more lung tissue and improve the survival quality of patients due to better pulmonary function, we believe that minimally invasive thoracoscopic surgery can bring more benefits to people with surgical indications and surgical procedure further standardization.
