Objective To explore a new model of medical humanity education in new situation. Methods Extensive survey was carried out among medical students,and discussion and consultation were hold to faculty and education administers.A new teaching model was established. Results A curriculum system with 1 or 2 core courses supported by some elective courses and social practice is under the process of implementation and achieved preliminary success.Conclusion The medical humanity education should pay attention to the development of connotation instead of pursuing the extension of quantity blindly,which means that students' school work must be eased by focusing on self-study and self-education.Medical students'life path with high-minded personality training should be strengthened.

AIM:To assess changes of tear film function in patients after pterygium excision combined with amniotic membrane transplantation.
METHODS:Totally 126 patients with pterygium excision with amniotic membrane transplantation from January 2011 to November 2013 were entered in the study. The tear breakup time ( BUT) , the Schirmer I test ( SⅠt) and tear ferning test ( TFT ) were elevated in the patients before and after pterygium excision combined with amniotic membrane transplantation. The examnation times were 1d before surgey, 1wk, 1, 2mo after surgery. Operation eyes were studied group, while opposite healthy eyes as control group.
RESULTS: Compared with the control group, BUT and TFT were significantly different in the eyes with pterygium (P<0. 05); However, no obvious difference was detected in the results of SⅠt (P>0. 05). The results of BUT and TFT at 1mo after surgery in study group were significantly better than 1wk (P<0. 05), while no significant difference compared with 2mo (P>0. 05); The tear film stability in the study group at 1wk after surgery was still inferior to the control group (P<0. 05) and there was no significant difference at 1, 2mo after surgery (P all>0. 05). SⅠt results did not differ between the different examination times(P>0. 05).
CONCLUSION:Tear film stability was broken in the eyes with pterygium. Pterygium excision combined with amniotic membrane transplantation can obviously restore the tear film function into normal state, and the tear film function could reach steady-state 1mo after surgery.

Objective To explore the anatomic characteristics of the peroneal perforator branches and its clinical application as vascularized flap transfer. Methods Twenty fresh cadaver specimen with 40 sides lower limbs were used in this study.Lead oxide gelatin was injected to the whole body,lower extremity radiaograph, spiral CT scan was then used to construct three demention visual model. The peroneal artery and its perforators were dissected,number of peferators,distance to fibular head,diameter and the length of the vascular pedicles were measured and analyzed. From July 2005 to October 2009, forty-three cases with skin defects were performed vascularized transfer in our study,surviving rate and postoperative function were followed up for 6 months to 2 years.Results Perforators were seen most at (9.80 ± 0.93)cm,(13.40 ±0.90) cm,(17.20 ± 1.13)cm,and (21.30 ± 0.77)cm beneath the fibular head with the artery branch diarneter(1.33 ± 0.39) mm,(1.30 ± 0.46)mm,(1.17 ± 0.30)mm,and (1.22 ± 0.23)mm,respectively,while the pedicle length was (5.87 ± 0.73)cm,(5.83 ± 1.73)cm,(5.44 ± 1.09)cm,and (5.10 ± 1.93) cm respectively.In clinic,42/43 free flaps survived.Postoperative outlook were satisfied except in 7 cases,the flaps looked bulky and needed secondary revision.All the donor calves showed good apperaence and function.Conclusion There are 4 regular perferators in lateral calf, while perforators in the middle 1/3 are bigger with relatively longer vascular pedicles which are appropriate for vascularized transfer.

Objective To investigate the application value of functional exercise pathway in enhanced recovery of patients undergoing hepatectomy.Methods Fifty primary hepatic carcinoma patients who had undergone liver resection in Anhui Province Hospital from December 2014 to August 2015 were randomly divided into experimental group (n =25) and control group (n =25).Postoperative length of hospital stay,hospitalization charges,complications,postoperative pain score,postoperative ambulation and intestinal ventilation time were compared between these groups.Measurement data with normal distribution were represented as ((x) ± s) and comprison between groups was analyzed using the t test.Comparisons of count data were analyzed by the x2 test.Results Postoperative length of hospital stay of the experimental group [(7.00 ± 2.27) days] were shorter than control group [(9.36 ± 4.58) days] (t =3.090,P =0.003),and hospitalization expense was lower in the experimental group [(28 184.57 ± 8 675.65) yuan] (t =2.281,P =0.025).Compared with control group (40％),the experimental group (20％) had lower overall complication incidence (t =4.286,P =4.286),and general complications incidence (8％) is lower than that in control group (24％),however,the incidence of operation characteristic complications had not statistical significance in two groups.Besides,the intestinal recovery time in the experimental group was shorter than control group (experimental group 36.56 hours,control group 45.24 hours,t =2.390,P =0.019).Conclusion The application of functional exercise pathway in postoperative enhanced recovery exercise of patients undergoing hepatectomy is safe and effective,which can reduce the patients' postoperative hospital stay,hospital costs,and the general incidence of complications incidence,and be helpful for the intestinal function recovery.
