In order to promote the optional subjects' function in perfecting knowledge construction and developing the character of the students,through analyses of the results of 670 classmates’selection of optional subjects,we know in detail what kind of optional subjects students like and need.Therefore based on how to organize teaching and manage optional subjects we bring up the suggestions for enhancing the optional subjects ' development and management:setting students as the center and increasing optional subjects,establishing the leading teacher's system,reforming teaching method,enriching teaching means,and strengthening the management of the examination of optional subjects.

Objective To observe the expression changes of heme oxygenase-1(HO-1) and its mRNA after spinal cord injury (SCI). Methods SD rats were randomly divided into normal (n=5), control (n=5) and experimental group (n=10). The rats were given no operation in the normal group, laminectomy only in the control and both laminectomy and traumatic injury in the experimental group. The SCI animal models were made by using a modified Allen's weight-drop device (50 g.cm) on T 12 . Rats were sacrificed at 1 and 3 days after injury. The distribution and content changes of HO-1 and its mRNA in spinal cord segments were observed by means of immunohistochemistry and in situ hybridization. Results Expression of HO-1 was mainly in neurons in the normal spinal cord. After injury, HO-1 expressed primarily in astrocytes and microglia and the distribution of positive cells closely correlated with intraparenchymal hemorrhage. Protein began to increase at the first day after injury. The expression intensity and the area of positive cells were (148.26?11.39) and (90.50?8.70)?10 3 ?m 2 respectively. At the third day, protein expressed more significantly with expression intensity of (128.03? 12.59) and area of (112.99?10.01)?10 3 ?m 2. The expression intensity and area of positive cells expressed by mRNA were (106.02?9.10) and (70.05?9.26)?10 3 ?m 2 respectively at the first day after injury, (85.82?9.07) and (87.37?10.95)?10 3 ?m 2 respectively at the third day after injury. There was significant difference between experimental and control groups ( P

The training of teaching ability is an important context of master course.Pathology Department of Xiang Ya School of Medicine take experimental teaching practice as the important way to improve their pathological experimental teaching skill.In this paper we introduced our experience.

Objective To determine whether the adjustment of the pusher of GTF was useful to decrease the degree of tilting of the femoral Ginther Tulip filter (GTF) in an in vitro caval model. Methods The caval model was constructed by placement of a 25 mm × 100 mm and two 10 mm ×200 mm Dacron graft inside a transparent bifurcate glass tube. The study consisted of two groups: left straight group (GLS) (n =100) and left curved group (GLC) (n = 100). In the GLC, a 10° to 20° angle was curved on the introducer.The distance (DCH) between the caval right wall and the hook was measured. The degree of tilting (DT) was classified into 5 grades and recorded. Before and after the GTF being released, the angle (ACM1, 2)between the axis of IVC and the metal mount, the distance (DCM1) between the caval right wall and the metal mount, the angle (ACF) between the axis of IVC and the axis of the filter and the diameter of IVC (DIVC) were measured. The data were analyzed with Chi-Square test, t test, rank sum test and Pearson correlation test. Results The degree of GTF tilting in each group revealed a divergent tendency. In group LC, the apex of the filter tended to be grade Ⅲ compared in group LS (x2 value 37. 491 ,P ＜0.01).The differences of most variables between GLS and GLC were considered as statistical significance(16. 60° vs.3.05°, 20.60° vs. 3.50°, -3.90°vs. -0.40°, 2.98 mm vs. 10.40 mm, - 10.95° vs. -0.485°,13. 17 mm vs. 10.06 mm, - 1.70° vs. 0.70°, t or Z values - 12. 187, - 12. 188, -8.545, -51.834,-11. 395,9. 562, -3. 596, P ＜ 0. 01). There exist significant positive correlation between ACM1 and ACF,ACM1 - ACM2 and DCH1 - DCH2 in each group, respectively(r values 0. 978,0. 344,0. 879,0. 627 ,P ＜0. 01),while significant negative associations are detected between DCH1 and ACF in each group , ACP and ACF in group LC(r values -0.974, -0.322, -0.702,P＜0.01). Conclusion The technique of adjusting the orientation of filter pusher had minimized the incidence and extent of GTF filter tilting in vitro.

Myringoplasty using exogenous collagen membrane was carried out in 10 rabbits (20 ears) after complete removal of drumhead. The healing results were observed at 10, 20, 40, and 60 d, after operation. The 19 ears were transplanted successfully. Meanwhile, observational comparisons were made of the histology and ultrastructural morphology of the rabbits tympanic membrane before and after transplantation. The results confirmed that the graft has a good property of biocompatibility.and that it is of great practical value in the transplantation of tympanic membrane.

Object To investigate the berberine in Coptis chinensis Franch. processed with various quantity of Evodia rutaecarpa (Juss.) Benth. and the components absorbed from E. rutaecarpa. Methods Taking berberine, evodiamine and rutaecarpine as targets, HPLC method was used to determine the components of C. chinensis, E. rutaecarpa, C. chinensis processed with 10%, 20%, 30%, 40%, 50% E. rutaecarpa. Results The content of berberine in C. chinensis processed with E. rutaecarpa decreased, and that of C. chinensis processed with 20% and 30% E. rutaecarpa was higher than the rest. C. chinensis processed with E. rutaecarpa absorbed the components of E. rutaecarpa really. Conclusion The suitable quantity of E. rutaecarpa is 20% when processing for C. chinensis.

AIM: To study compatibility rationality of combination of Paeonia lacliflora and Glycyrrhiza uralensis. METHODS: The effective combination of paeoniflorin(44% purity),glycyrrhizic acid(50% purity) and liquorice flavones(52% purity),glycyrrhizic acid(50% purity) and liquorice flavones(52% purity) were respectively administered to rats.Pharmacokinetic change of these constituents in rat blood was studied. RESULTS: The pharmacokinetic parameters of these constituents in rat blood showed that the increases in AUC and C_(max) of effective combination group were more than that of glycyrrhizic acid group or that of liquorice flavones group.T_(max) of the former was extended with respect to the latters.Clearance of effective combination markedly slowed down. CONCLUSION: The effective combination of paeonia lacliflora and Glycyrrhiza uralensis have the advantage of either Paeonia lacliflora or Glycyrrhiza uralensis.

Objective To study the effect of S-adenomethionine on early stage recovery of transplanted liver.Methods From January 2010 to October 2012,57 liver transplantation patients were divided into 2 groups beginning the first day:group A,23 patients were treated with routine liver-protecting therapy,including glycyrrhizin,glutathione,albumin; group B,34 patients treated with additional S-adenomethionine (Transmetil).AST,ALT,T-BIL,D-BIL,γ-GT,ALB and ALP were compared between the two groups at pre-operation and post-operation day 1,day 4,day 7 and day 14.Results All patients suffered from preoperative hyperbilirubinemia,decreased ALB and elevated concentration of AST,ALT,γ-GT and ALP.On the first day after transplant,AST,ALT,T-BIL,D-BIL and γ-GT elevated and ALB decreased significantly in all cases compared with that before operation (respectively t =10.493,7.089,6.584,15.134,5.164,10.344,5.289,13.034,3.389,4.366,all P ＜ 0.01).On the contrary,the value of ALB was lower (respectively t =8.239,11.662,all P ＜ 0.05).On the fourth day posttransplant,ALB level was higher and that of other parameters were lower in group B when compared with group A (respectively t =2.536,2.736,2.218,3.318,4.804,2.892,all P ＜ O.05).This tendency of liver function improvement continued till postoperative day 7 in all cases while the differences between the two groups remained significant (respectively t =6.107,3.256,2.929,11.688,8.964,2.857,all P ＜ 0.05)except for γ-GT.On day 14,while T-BIL and D-BIL in group B were lower than that in group A (respectively t =4.413,8.493,all P ＜0.001),differences of liver functions were not significant between the two groups (respectively t =1.916,1.414,1.168,1.035,1.604,all P ＞ 0.05).Conclusions Transmetil promotes the recovery of transplanted liver's function,elevates the concentrantion of ALB and reduces the concentration of AST,ALT,T-BIL,D-BIL,γ-GT and ALP at early stage after liver transplant.
