Objective To explore the effect of GAS MAN assisted instruction on theory learning of volatile anesthetics in anesthesiology residency training.Methods A total of 32 residents in the first stage of anesthesiology training were enrolled and randomly assigned to either study(S) or control (C) group.Theory-test l(Test-1) was conducted for all residents after the lecture-based learning (LBL).Next,reference book self-reading strategy was used in both groups while computer-based simulation(CBS) using GAS MAN was only developed in S group.Then,theory-test 2(Test-2)was conducted for residents in both groups and residents in S group completed the questionnaire smvey.In addition,thirty-four resident teachers observed the CBS courses and completed the questionnaire smvey.Results The mean scores of Test-1 did not differ significantly between the two groups(P=0.64).However,the mean Test-2 score of S group(81.3 ± 13.6) was significantly higher than that of C group(61.3 ± 15.4) (P=0.001).100％(16/16) residents believed that CBS was beneficial to the theoretical study of volatile anesthetics,93.8％(15/16) residents considered GAS MAN could help understand the concepts and improve efficiency during self-learning.97.1％ (33/34) and 91.2％ (31/34)resident teachers agreed that CBS was helpful for analyzing complex concepts and improving study effectiveness,respectively.Conclusions CBS using GAS MAN improves theory knowledge and study effectiveness for anesthesia residents.Both residents and resident teachers find GAS MAN highly ac ceptable.Therefore,GAS MAN has the potential to be the assistant teaching tool for LBL in anesthesiology residency-training program.

Objectives To analyze the incidence of cranial nerve injury in patients after receiving carotid endarterectomy ( CEA) in a single-center and to investigate its correlation with surgical experiences. Methods The clinical data of patients underwent CEA at Beijing Xuanwu Hospital, Capital Medical University from January. 2001 to December 2013 were analyzed retrospectively. Cranial nerve injury was assessed at day 7 after procedure according to the clinical symptoms,and they were followed up at 1,3,6, and 12 months. The incidence of permanent cranial nerve injury was evaluated. The incidences of permanent cranial nerve injury were further analyzed at two time periods ( from January 2001 to September 2011 and from October 2011 to December 2013 ) . Results ( 1 ) A total of 598 consecutive patients treated with CEA were enrolled,and 15 (2. 5%) of them had cranial nerve injury,including 2 (0. 3%) facial nerve injury,7 (1. 2%) hypoglossal nerve injury,and 6 (1. 0%) vagus nerve injury. Only 1 case (0. 2%) did not recover completely at 6 months after procedure. ( 2 ) The patients with cranial nerve injury were 10 (3. 2%,10/308) and 5 (1. 7%,5/290) respectively from January 2001 to September 2011 and from October 2011 to December 2013). There was no significant difference (P < 0. 05). Conclusion The incidence of cranial nerve injury was low after CEA,and most patients could recover completely. The increased surgical experiences did not show the reduction of cranial nerve injury rate evidently after CEA.

Aim To study the inhibitory effect of isoquercitrin on Raf/MEK/ERK signaling pathway in HepG2 cells.Methods MTT was used to detect the proliferation of human liver cancer HepG2 cells after the treatment of isoquercitrin.The morphology and growth of cells were observed under inverted microscope after the different concentrations of isoquercitrin(0, 40, 80, 160, 320 μmol·L-1) to treat HepG2 cells for 24 and 48 h.Cell cycle was assessed by flow cytometry.Ras, Raf, MEK, ERK expression was assayed by Western blot, and mRNA expression was detected by quantitative fluorescence PCR.Results Isoquercitrin could inhibit the growth of HepG2 cells in a concentration-and time-dependent manner.Typical morphological changes of apoptosis were observed by inverted microscopy after HepG2 cells were treated with different concentrations of of isoquercitrin for 24 h or 48 h.The cell cycle assay showed that with the increasing concentration of isoquerditrin, the number of cells that was arrested in G1 phase gradually increased.Compared with the blank group, the expressions of Ras, Raf, MEK, ERK mRNA were down-regulated, and related proteins expression were also down-regulated(P<0.05), and these results had statistical significance.Conclusion Isoquercitrin can induce the apoptosis of HepG2 cells, which may be related to the Raf/MEK/ERK signaling pathway.
