The Problems in Rural English Teaching and the Optimization Path: A Study Based on the Chinese General Social Survey Data

The new curriculum,new ideas and new requirements concerning English teaching have made the rural English teaching face unprecedented challenges. There are many problems contributing to the poor effect of rural English teaching,such as outdated teaching equipment,unreasonable curriculum design,insufficient teaching staff,asymmetrical teaching content,family education and students' personal problems. Based on the Chinese General Social Survey data,it is found that in terms of English reading,English speaking or English writing,the current English level of China's rural residents is lagging behind. From the average,the reading level of rural residents is better than the speaking and writing level,but the paired T-test results show that there are no significant differences between them,suggesting that under the current system of rural English teaching,the English level of rural residents is constrained to a low level. To improve the rural English teaching in the future,it is necessary to pay close attention to the following aspects: stabilizing the investment in rural education; optimizing the English teaching content; converting the philosophy of education; increasing teacher training; establishing the new linkage system.

Long-term survival after resection of pancreatic cancer:A single-center retrospective analysis

AIM: To retrospectively analyze factors affecting the long-term survival of patients with pancreatic cancer who underwent pancreatic resection.METHODS: From January 2000 to December 2011,195 patients underwent pancreatic resection in our hospital.The prognostic factors after pancreatic resection were analyzed in all 195 patients.After excluding the censored cases within an observational period,the clinicopathological characteristics of 20 patients who survived ≥ 5(n = 20) and < 5(n = 76) years were compared.For this comparison,we analyzed the patients who underwent surgery before June 2008 and were observed for more than 5 years.For statistical analyses,the log-rank test was used to compare the cumulative survival rates,and the χ2 and Mann-Whitney tests were used to compare the two groups.The CoxHazard model was used for a multivariate analysis,and P values less than 0.05 were considered significant.A multivariate analysis was conducted on the factors that were significant in the univariate analysis.RESULTS: The median survival for all patients was 27.1 months,and the 5-year actuarial survival rate was 34.5%.The median observational period was 595 d.With the univariate analysis,the UICC stage was significantly associated with survival time,and the CA19-9 ≤ 200 U/m L,DUPAN-2 ≤ 180 U/m L,t u m o r s i ze ≤ 2 0 m m,R 0 re s e c t i o n,a b s e n c e o f lymph node metastasis,absence of extrapancreatic neural invasion,and absence of portal invasion were favorable prognostic factors.The multivariate analysis showed that tumor size ≤ 20 mm(HR = 0.40; 95%CI: 0.17-0.83,P = 0.012) and negative surgical margins(R0 resection)(HR = 0.48; 95%CI: 0.30-0.77,P = 0.003) were independent favorable prognostic factors.Among the 96 patients,20 patients survived for 5 years or more,and 76 patients died within 5 years after operation.Comparison of the 20 5-year survivors with the 76 non-survivors showed that lower concentrations of DUPAN-2(79.5 vs 312.5 U/mL,P = 0.032),tumor size ≤ 20 mm(35% vs 8%,P = 0.008),R0 resection(95% vs 61%,P = 0.004),and absence of lymph nodemetastases(60% vs 18%,P = 0.036) were significantly associated with the 5-year survival.CONCLUSION: Negative surgical margins and a tumor size ≤ 20 mm were independent favorable prognostic factors.Histologically curative resection and early tumor detection are important factors in achieving long-term survival.
