At present, many domestic police colleges are constantly promoting foreign exchanges and cooperation. They have established extensive inter-school cooperation with foreign police education and training institutions and police colleges. More and more Chinese students of police colleges go abroad to judicial institutions and police colleges of various countries for short-term study or visit. Due to cross-cultural differences and other factors, these international Chinese students often encounter culture shock at English-speaking countries. This article takes eleven students from Nanjing Forest Police College (NFPC) as the survey object, conducts dynamic research applying interviews and questionnaires, explores the culture shock they experienced in six-month life and learning in 2019 in Canada, analyzes the internal and external causes, and proposes the countermeasures to cross-cultural adaption for international Chinese students in police colleges.

The conditional survival of patients after frontline therapy for diffuse large B-cell lymphoma (DLBCL) approaches that of the general population once patients have survived disease free for 2 years. We sought to determine the conditional survival of patients among patients with relapsed de novo DLBCL successfully undergoing an autologous stem-cell transplant (ASCT) after first relapse. A total of 478 patients with de novo DLBCL, relapsed after 1 treatment from the Collaborative Trial in Relapsed Aggressive Lymphoma (CORAL) and LY.12, were included. Patients were followed prospectively after ASCT for a median of 5.3 and 8.2 years, respectively. Individual patient data were analyzed for event-free survival (EFS) and overall survival. Standardized mortality ratios (SMRs) were estimated using French and Canadian life tables. The EFS estimates declined with each year of follow-up after ASCT and were 50.1% (95% confidence interval [CI]: 43.7% to 56.3%) and 43.4% (95% CI: 36.7% to 49.9%) at 5 years in CORAL and LY.12, respectively. The rate of death stabilized once patients achieved at least 4 years of EFS. Compared with the age- and sex-matched population, the SMR was significantly higher until 5 years after ASCT, when values were no longer statistically significant. Patients undergoing ASCT for relapsed DLBCL continue to have a higher rate of death at least until they have survived event free for 5 years. These observations can help to determine endpoints for future clinical trials in this population and for patient counseling.
