Objective To write the school-based teaching material of pathology,and apply it to the students in higher vocational colleges to evaluate the application effect.Methods Two classes of clinical medical students of Grade 201 1were divided into two groups:the experimental group(Class1,58 students) and the control group(Class2,60 students).Both of the two groups take the integration of theory and practice teaching method.The traditional teaching material was applied in the control group while the school-based teaching materials were adopted in the experimental group.Statistical analysis software SPSS 13.0 and two samples t test were used to compare the preparing effect before the class,case study effect and the final examination of the two groups.After the end of the course,students' teaching satisfaction questionnaire was conducted,and the results of the survey for the rank sum test were analyzed.Results The scores of preparing effect before class were higher in experimental group(84.4 ±6.2) than those in the control group(78.2 ±5.8),t=5.61,P=0.001; the case study effect in experimental group(78.6 ± 6.6) was higher than that of the control group(72.8 ± 5.3),t=5.27,P=0.002; there was no significant differences in the final examination between the two class [experimental group (83.5 ± 6.8),control group (81.6 ± 6.9)],t=1.51,P=0.183.The questionnaire shows,in the aspect of the difficulty of teaching material,the degree of satisfaction in the experimental group(satisfied:28,general:30,unsatisfied:0) was higher than the control group(satisfied:18,general:37,unsatisfied:5),Z=-2.43,P=0.015; in the aspect of reading interest,the degree of satisfaction in the experimental group(satisfied:32,general:25,unsatisfied:1) was higher than the control group(satisfied:22,general:35,unsatisfied:3),Z=-2.09,P=0.036; in the aspect of emphasizing on the key point,the degree of satisfaction in the experimental group(satisfied:20,general:38,unsatisfied:0) was higher than the control group(satisfied:12,general:39,unsatisfied:9),Z=-2.72,P=0.007; in the aspect of self-study effect,the degree of satisfaction in the experimental group(satisfied:20,general:38,unsatisfied:0) was higher than the control group(satisfied:16,general:39,unsatisfied:5),Z=-3.13,P=0.002; but there was no significant differences in classroomlearning effect(experimental group:satisfied,38,general,20,unsatisfied,0; control group:satisfied,36,general,23,unsatisfied,1),Z=-0.68,P=0.497.Conclusions The school-based teaching material can contribute to the students' self-learning,enhancing the students' interest of learning and knowledge-application ability.

[Adstract] Micro-lecture, as the main teaching form of MOOC and SPOC network teaching platform, is deeply welcomed by the majority of students. Pathology is the bridge connecting basic medicine and clin-ical medicine in medical education, which has such characteristics as many knowledge points, dispersion and obscurity, etc. Therefore, the production of micro courses is based on the knowledge points, and according to the characteristics of the knowledge points, it should also be applied reasonably according to the charac-teristics of each chapter. Adopting the teaching of self-study after class and teachers and students' discussion in class for micro courses can not only greatly improve the quality of teaching, but also develop the students' ability of independent thinking and the ability to analyze and solve problems, which transforms the teaching of pathology from pure knowledge to ability.

Objective To evaluate the correlation between regional blood perfusion,metabolism and angiogenesis in breast cancer.Methods The PET/CT functional imaging technique was applied to quantitatively detect the central and marginal blood perfusion parameters including blood flow(BF),blood volume(BV)and permeability of surface(Ps),and metabolism index of standard uptake value(SUV)of the tumor in 33 breast cancer patients.The expression of CD31.CD105 and VEGF in paraffin section of breast cancer were detected by immunohistochemical method,then MVD(CD31)and MVD(CD105)were obtained.The relationship between the regional blood perfusion and metabolism and MVD(CD3 1),MVD(CD105)and the expression of VEGF were analyzed. Results There was significant correlation of MVD (CD31)with BF of marginal region(P<0.05).There were significant correlations of MVD(CD105)with BF.PS and SUV(P<0.05). Conclusions Regional blood perfusion,metabolism is correlated with angiogenesis in breast cancer tissue.PETT/CT regional blood perfusion and metabolic imaging iS a noninvasive method which can be used to estimate angiogenesis status clinically in breast cancer.

Objective To evaluate neurovascular anatomical relationship in patients with trigeminal neuralgia.Methods 49 patients with neuralgia were examined by MRI 3D-CISS in combination with 3D-TOF and MPR technique.The MRI findings were compared to the partial operative results.Results 13 patients who underwent surgery were considered as a responsible compression of vessel on 3D-CISS and 3D-TOF imaging,the compression caused by artery and vein was seen in operation in 10 cases and 3 cases respectively.18 (90%) of 20 patients with the symptom of maxillary division had neurovascular compression at the medial site of the root of trigeminal nervus,while 15(79%) of 19 patients with the symptom of mandibular division had compression at the lateral site.Conclusion 3D-CISS MR imaging is useful in the detection of neurovascular relationship and correlation between the region of neuralgic manifestation and the site of trigeminal nerve compression.

Objective:This study aimed to investigate the possible mechanism of 32P colloid induced apoptosis of craniopharyngi-oma (CP) cells in vitro and the relationship between dose effect and time effect. Methods:This study established a primary cell culture of CP limited subculture cell line. Methyl thiazolyl tetrazolium (MTT) assay was performed to plot the cell survival curve after the CP cells were treated with 32P colloid at different concentrations and time. Apoptotic rate was detected by flow cytometry(FCM). Apoptosis related DNA was investigated by TUNEL fluorescent staining. The morphological characteristics of apoptotic cells were determined by Hoechst33342 fluorescence staining. The ultrastructure of apoptotic cells was investigated by transmission electron microscopy (TEM). Results:Hoechst33342 fluorescence staining, TUNEL fluorescence staining, and TEM revealed that 32P colloid induced the apoptosis of CP cells. 32P colloid reduced the survival rate and increased the apoptotic rate of CP cells as concentration (0 MBq/mL to 14.80 MBq/mL) and time (1 d to 14 d) were increased. Conclusion: 32P colloid could effectively inhibit the growth of CP cells and induce apoptosis in vitro. High concentrations and prolonged time could induce a remarkable effect.

ObjectiveTo explore the efficacy and safety of percutaneous antegrade stenting in the treatment of ureteral obstruction after renal transplantation.MethodsWe retrospectively reviewed 11patients with renal graft ureteral obstruction (2 cases of acute obstruction and 9 cases of chronic obstruction) from March 2009 to March 2011.The etiology of the obstruction was renal graft-ureter-bladder anastomotic stricture in 5 cases,stone obstruction in 2 cases,and undetermined in 4 cases.Renal graft and collecting system were examined by ultrasonography preoperatively to select suitable puncture position,and then ureteropyelography was performed under X-ray guidance.When the obstruction location was clear,the urology guidewire was implanted to the bladder by needle,and then guidewire was released by cystoscopy.Ureteral stent was implanted along the guidewire,and upper ureteral stents was observed under X-ray. After removal of guidewire,the stent location was confirmed once again.The renal pelvis fistula drainage lasted for 1-2 weeks,and ureteral stent to 6 months to one year.Ultrasound and renal function were tested after 1week,1month,3 months and 6 months,and then every six months.ResultsOperation was done successfully in 10 patients,and failed in one case due to a long segment of ureteral stenosis.The operating time of ureteral stent implantation was 54±27 min.Serum creatinine of patients was reduced from preoperative 326±147 to postoperative 89±49 μmol/L.During a follow-up period of 6 to 27 months,no complications occurred.ConclusionPercutaneous antegrade stenting in the treatment of ureteral obstruction after renal transplantation is safe and effective.

Objective To study the relationship between rs290487,rs7903146 of transcription factor 7-Like 2 (TCF7L2) gene and post-transplantation diabetes mellitus in Han Zhejiang population.Method We genotyped two single nucleotide polymorphisms (SNPs) across the TCF7L2 gene in 90 unrelated post-transplantation type 2 diabetes mellitus (PTDM) patients,112 unrelated non-PTDM patients,and a set of post-transplantation diabetes mellitus patients (n =68).Genotyping was performed using direct sequencing SNP Genotyping Assays.The association of SNPs with post-transplantation diabetes mellitus was analyzed.Result In this study,there was statistically significant difference in the T-allele of TCF7L2.rs7903146 between PTDM group (5.1％) and non-PTDM group (1.3％) (P＜0.05).For rs7903146,the frequencies of genotype C/C,C/T (70.0％) and T/T (35.8％) was statistically significant in PTDM group (P＜0.05).For rs290487,the frequencies of genotype C/C,C/T and T/T was 14.7％,38.2％ and 47.1％ respectively in PTDM group,P＞ 0.05.The incidence of PTDM was significantly higher in patients with the CT genotype (odds ratio 18.54 [95％ CI 1.21-282.26],P =0.03).Conclusion With the current sample size,we found that the CT genotype of rs7903146 was significantly associated with post-transplantation diabetes mellitus.
