Objective To research the affection and problem of Curriculum integration teaching method in eight-year term Medical Education.Methods Combination teaching and tradition teaching methods were employed in 100 students (Eight-year-term) and 127 students (Seven-year-term) respectively.A questionnaire survey and teaching effect were analyzed at last (employx2 analysis).Results Currculum integration is more acceptable(x2 =3.92,P ＜ 0.05),effective (x2 =11.07,P ＜0.01 ),systematic (x2 =11.82,P ＜ 0.01 ) and improve self-study ability better(x2 =8.51,P ＜ 0.01 ).But it's not helpful for the study enthusiasm(x2 =0.90,P ＞0.05).Conclusion Combination teaching method is more acceptable and effective than tradition method.However,the enthusiasm of study is not improved obviously.Combination Curriculum integration teaching method is a good one and worth popularizing.

We propose a novel strategy for multi-atlas-based image segmentation of the prostate on magnetic resonance (MR) images using an ellipsoidal shape prior constraint algorithm. An ellipsoidal shape prior constraint was incorporated into the process of multi-atlas based segmentation to restrict the regions of interest on the prostate images and avoid the interference by the surrounding tissues and organs in atlas selection. In the subsequent process of atlas fusion, the ellipsoidal shape prior constraint calibrated and compensated for the shape prior obtained by the registration technique to avoid incorrect segmentation caused by registration errors. Evaluation of this proposed method on prostate images from 50 subjects showed that this algorithm was effective and yielded a mean Dice similarity coefficients of 0.8812, suggesting its high accuracy and robustness to segment the prostate on MR images.

The purpose of this study was to investigate the efficacy of treatment with haploidentical donor's lymphocyte infusion(hiDLI) combined with interleukin-2 (IL-2) after transplantation of autologous peripheral blood stem cells mixed with haploidentical allogeneic bone marrow (mix-HSCT) for acute myeloid leukemia (AML). 49 patients diagnosed as AML were enrolled in this study. After preconditioning with TBI plus VEMAC regimen, all patients received mix-HSCT. Autologous peripheral blood hematopoietic stem cells were mobilized with chemotherapy-combined G-CSF, and haploidentical allogeneic bone marrow cells were not mobilized with G-CSF. 33 patients in test group were treated with hiDLI plus IL-2 for 1-8 times after hematopoietic reconstruction, 16 patients in control group received mix-HSCT only. All the patients were followed-up for more than 3 years. The results showed that all the patients obtained hematopoietic reconstruction, and no graft-versus-host disease (GVHD) was found. In two groups, the median time of absolute neutrophil count (ANC) ≥ 0.5×10(9)/L was 14 (12 - 18) and 14 (11 - 16) days, and WBC count ≥ 4.0×10(9)/L was 17 (16 - 22) and 18(17 - 20) days, Plt count ≥ 50×10(8)/L were 25 (24 - 29) and 25 (23 - 26) days. 9 patients in test group formed mixed chimerism (46XX/46XY) and sustained about 3 - 12 months; disease-free survival (DFS) was 63.6%, 3 patients in control group formed mixed chimerism (46XX/46XY), persistent about 3-6 months; DFS was 50.0%. It is concluded that treatment with hiDLI plus IL-2 after mix-HSCT for AML patients may increase DFS efficiently.

OBJECTIVETo explore the expression of origin recognition complex 1 (ORC1) during the DNA replication of vascular muscle cells (VSMC).

METHODSVSMC of thoracic aorta in rats were obtained by the adherence method of tissue culture. The cell synchrony was obtained by the method of double-thymidine block, colchicine treatment and serum starvation. The expression of ORC1 mRNA at different cell cycles of VSMC was determined by RT-PCR and the protein expression of ORC1 was analyzed by Western blot.

RESULTSCultured VSMC were identified by light microscope and immunocytochemistry. Significant expression of ORC1 mRNA and protein in a quiescent stage of VSMC were not observed. Upon synchronization, the expression of ORC1 mRNA was significantly higher at G(1)/S phase of VSMC than that at S and G(2)/M phases. The expression of ORC1 protein followed same changes as the ORC1 mRNA expression at different stages of cell cycles.

CONCLUSIONORC1 may be an important regulatory factor at the initiation of proliferative process of VSMC.

OBJECTIVETo analysis the changes of two chemical constituents, namely 2, 3-dihydro-3, 5- dihydroxy-6-methyl-4H-pyran-4-one (DDMP) and 5-hydryoxymethyl-furfural (5-HMF) produced in Radix Polygoni Multiflori after processing, with processing time, and to determine the contents of 5-HMF in samples of Radix Polygoni Multiflori and Radix Polygoni Multiflori preparata.

METHODAn HPLC method was applied with a Zobax SB-C18 (3.9 mm x 150 mm, 5 microm) column by a elution using methanol-water (10: 90) as the mobile phase. The detection was set at UV 280 nm.

RESULTThe contents of DDMP were increasing with the processing time until 24 hour, followed by a decrease until 60 hour process. The contents of 5-HMF were increasing gradually throughout the 60 hour steaming process. The contents of 5-HMF in 11 samples of Radix Polygoni Multiflori preparata were from 0.013% to 0.101%, and only one in 4 samples of Radix Polygoni Multiflori containing trace amount of 5-HMF.

CONCLUSIONThe chemical components in Radix Polygoni Multiflori were changed during the processing procedures. Therefore, the processing of Radix Polygoni Multiflori should be controlled and standardized.

OBJECTIVETo observe the influence of guinea pig mesenchymal stem cells (MSCs) culture in vitro on the immunological status in heterogeneous recipient, and to evaluate the immunomodulation of MSCs to the immune rejection of liver xenotransplantation.

METHODSThe mononuclear cell fraction obtained by centrifugation over Percoll was cultured in vitro. Cell surface epitopes were analyzed by flow cytometry technique, and MSCs were incubated at the addition of adipocyte induction media, and stained in Oil Red O. The immunoglobulin and complement in rat recipient serum were assayed after infusion of donor MSCs. Thirty guinea pigs and thirty Wistar rats were randomly divided into three groups. All rat recipients undertook cyclophosphamide (CTX) infusion. Group A was MSCs infusion group, group B was saline infusion group and group C was dexamethasone (DXM) infusion group. Orthotopic guinea pig to rat liver transplantation model was established. The survival time and the immunopathology of graft were observed.

RESULTSAccording to flow cytometry assay, MSCs were positive for CD44 and CD29, while negative for CD34 and CD45. Lipid droplets were found in the MSCs cytoplasm after being incubated in adipogenic inducation media. The concentrations of IgG, IgM, C3 at all time point after MSCs infusion were significantly decreased than before (P < 0.05), while the concentrations of IgA and C4 did not changed. The survival time of group A (431 +/- 27 min) was obviously longer than group B (148 +/- 16 min) and group C (141 +/- 22 min) (P < 0.01). The intense hyperacute rejection rapidly occurred of group B and C after blood re-perfusion. The severe immunopathological injury could be observed at the grafts of group B and C. However, the hyperacute rejection of group A occurred slightly.

CONCLUSIONSMSCs can be identified by virtue of cell morphology, membrane phenotype and differential potential. MSC may play a role in the immunosuppression in hyperacute rejection in the liver xenotransplantation.

BACKGROUNDConventional high ligation and stripping of the great saphenous vein (GSV) has a good curative effect but is highly traumatic with a considerable relapse rate. Subfascial endoscopic perforator surgery (SEPS) plus endovenous laser treatment (EVLT) could be applied as individual therapy. This study aimed to evaluate the feasibility of performing combined SEPS and EVLT without impacting GSV in the management of valvular insufficiency of the lower-limb venous perforators.

METHODSPlacement of lower-limb venous perforator insufficiency was marked by ascending phlebography in 83 affected limbs from September 2010 to June 2011. After randomization, SEPS was performed on 41 limbs to address the insufficiency of the venous perforators under the deep fascia, in combination with EVLT to close the superficial varicose veins without impacting the GSV. The remaining 42 limbs were treated using traditional GSV phlebectomy as controls.

RESULTSPostoperatively, all varicose veins were resolved, with lightening of the pigmentation and healing of the ulcer. Within a follow-up period of 5 - 11 months, no symptoms had recurred. Compared with the control group, the operation time, the number of incisions sutured, and the in-hospital time decreased on average by 1.5 hours, 4.7, and 6.8 days, respectively (P < 0.01 in all cases).

CONCLUSIONCombined SEPS and EVLT for treatment of valvular insufficiency of the lower-limb venous perforators offer the advantages of microtrauma and rapid cure.
