The present study aims to investigate corrective feedback and draw enlightening conclusions:1) Different corrective feedback types have different effects on second language acquisition; 2)The effect of corrective feedback is also influenced by the feedback timing, explicitness of the feedback and learners' individual differences; 3) Teachers should consider feedback types, feedback timing, and individual differences of students based on teaching contents when providing corrective feedback in foreign language teaching.展开更多

A retrospective analysis was made of surgical timing and curative effect of the surgical methods.RESULTS:The effectiveness rate of the methods was 74.12% for 1 310 patients after onemonth follow-up. In this series,the disability rate was 44.82% 3–6 months after the operation. Among the 1 310 patients,241(18.40%) patients died after the operation. If hematoma volume was >80 mL and the operation was performed within 3 hours,the mortality rate of group A was signifi cantly lower than that of groups B,C,D,and E(P<0.05). If hematoma volume was 50–80 mL and the operation was performed within 6–12 hours,the mortality rate of groups B and D was lower than that of groups A,C and E(P<0.05). If hematoma volume was 20–50 mL and the operation was performed within 6–24 hours,the mortality rate of group C was lower than that of groups A,B and D(P<0.05).CONCLUSIONS:Craniotomy through a bone f lap is suitable for patients with a large hematoma and hernia of the brain. Stereotactic drilling drainage is suggested for patients with hematoma volume less than 80 mL. The curative effect of HICH individualized treatment would be improved via the suitable selection of operation time and surgical method according to the position and volume of hemorrhage.展开更多

Almost half of the patients with CRC will develop liver metastases during the course of their disease. The liver surgeon dealing with colorectal liver metastases faces several surgical dilemmas especially in the setting of the timing of operation. Synchronous resectable metastases should be treated prior or after induction chemotherapy? Furthermore in the case of synchronous colorectal liver metastases which organ should we first deal with, the liver or the colon? All these questions are set in the editorial and impulse for further investigation is put focusing on multidisciplinary approach and individualization of treatment modalities.展开更多
