Journal of Medical Postgraduates 2003;0(09):-
Objective:To establish the model of pancreaticoduodenal transplantation in rats. Methods:The enteric drained whole pancreas duodenal transplantation model was investisated. The donor aortic segment including the celiac, superior mesenteric divergence were anastomosed with recipient abdominal aorta with end to side. The donor portal was cuff-anastomosed with left renal vein. The graft duodenum were anastomosed with the host jejunum with end to side. Results:Eighty-nine operations were performed and 51 rats were successful, of which all graft of successful case had endocrinium function. Conclusion:This model for pancreas transplantation is reliable.

4.Vitrectomy of rhegmatogenous retinal detachment in morning glory syndrome
International Eye Science 2010;10(3):424-426
We report a case of retinal detachment in morning glory syndrome(MGS). We think that identification of the retinal break, removal of the traction force by vitrectomy, the use of long-acting gas as endotamponade, all contributed to the successful treatment of the disease. The pathogenic mechanisms of the disease and the function of B-scan to the diagnosis are included.

Objective In order to study the relationship between the platelet activation sign:P-selectin(GMP 140 ) expression and human IgA nephropathy.Methods Expression of platelet membrane glucoprotein Ⅱb/Ⅲa(GP Ⅱb ,GP Ⅲa ) in blood for IgA nephropathy patients(n=46) was investigated by flow cytometry methods.Results In IgA nephropathy the up-regulated GMP 140 expression in blood was significantly higher than that in normal humans.Conclusions GMP 140 might play an important role in pathogenesis of IgA nephropahty,and the level of GMP 140 in blood might predict renal outcome in IgA nephropathy.

Objective The patients with non-small cell lung cancer ( NSCLC) are still at risk of brain metastasis after surgi-cal treatment.The study was to investigate the clinical characteristics and the risk factors for postoperative brain metastasis in patients with NSCLC in order to provide references for prophylactic cranial irradiation ( PCI) . Methods The clinical and prognostic data of 213 patients with NSCLC in our department of oncology from February 2008 to February 2012 were retrospectively analyzed.The occur-rences of postoperative brain metastasis in NSCLC patients with different characteristics were observed.Cox model was used to investi-gate the risk factors for postoperative brain metastasis in patients with NSCLC. Results The overall cumulative rate of brain metasta-sis was 23.9%(51/213) and the rates of brain metastasis at 1-year, 2-year, 3-year after surgery were 6.1%, 14.1%, 22.5% re-spectively.Univariate analysis showed that the rates of postoperative brain metastasis in NSCLC patients with different ages, histological types, tumor stages and CEA levels were statistically significant (P<0.05).Cox regression showed that adenocarcinoma (HR=2.00, 95%CI:1.11~3.64), lung cancer stageⅢ(HR=3.70, 95%CI:1.67~8.25) and high CEA (≥5.0μg/L)(HR=3.16, 95%CI:1.60~6.25) were risk factors for postoperative brain metastasis in patients with NSCLC.The survival time in NSCLC patients with brain metastasis was remarkably lower than that in patients without brain metastasis (P<0.05). Conclusion The NSCLC pa-tients with adenocarcinoma, III stage disease, or high CEA are more likely to develop brain metastasis after surgery, which should be the focus of PCI.

Objective To evaluate the results of Four-Step methods in traditional Chinese medicine Course.Methods 40 five-academic-year clinical medical students and 40 seven-academicyear undergraduate students were randomized assigned into experimental group (n=40, 20 five-academicyear clinical medical students and 20 seven-academic-year students) and control group (n=40, 20 five-academic-year students and 20 seven-academic-year students).The control group received conventional teaching, while four-step teaching break the gap between Chinese medicine and western medicine, build the base, form the framework of Chinese medicine and extend knowledge was implemented in the experimental group.Through questionnaire score, group discussion, the final evaluation of the theory and clinical training evaluation, the learning of the experimental group students and the control group students was compared.SPSS 18.0 statistical software was used and t test was employed to make analysis of the relevant data.Results The questionnaire at the end of the semester showed that the average score of students in the experimental group (36.18 ± 0.96) was higher than that in the control group (26.62 ± 1.00), and the difference was statistically significant (P=0.017).In the discussion at the end of the semester, the experimental group paid more attention to the theory and technology of traditional Chinese medicine's learning persistence in future and its application in their professional practice.Scores in theory test were higher in seven-academic-year students in experimental group (88.40 ± 8.79) than in control group (82.15 ± 6.83) and the difference was statistically significant (P=0.017), but there was no difference in five-academic-year students between experimental group (75A0 ± 12.09) and control group (77.85 ± 11.99), which was not considered statistically significant different (P=0.524).In clinical practice, the rate of outstanding students in the experimental group of seven-academic-year was five percentage points higher than the control group, while the rate of outstanding students in the experimental group of five-academic-year was 10 percentage points higher than the control group.Conclusions Four step teaching is helpful to stimulating the learning enthusiasm of the students of traditional Chinese medicine, expanding students' vision of medical field, and promoting their construction of a more comprehensive medical knowledge framework.

T lymphoblastic leukemia/lymphoma (T-ALL/LBL) is a kind of lymphoblastic malignant tumors orientated in T-cell line with poor clinical effects. Its molecular genetics is mainly correlated with antigen receptor gene, abnormal chromosome, oncogene activation, tumor-suppressor gene inactivation and molecular pathways. This article will review the latest research progress of the molecular genetics in T-ALL/LBL to explore the index of prognosis and possible therapeutic targets.

Objective To investigate the relationship of vascular endothelial growth factor(VEGF)with the invasion and metastasis of non-Hodgkin lymphoma.Methods The levels of serum VEGF was measured by enzyme linked-immunoadsorbent assay(ELISA).Comparing the parameters between NHL group and the control group.Compared the parameters with different groups divided by clinical stage,the effect of the treatment,the level of plasma LDH and effect of treatment.Analyzed the correlation of the levels of serum VEGF and plasma LDH in patients of NHL.Results The levels of serum VEGF are remarkablely higher in patients than that in the control group(P<0.05).The levels of serum VEGF in the group of Ⅲ,Ⅳ clinical stage are higher than that in the group of Ⅰ,Ⅱ clinical stage,but no significant difference(P>0.05)were observed.The level of serum VEGF is higher in the group of none CR than the group of CR(P<0.05).The level of serum VEGF is higher in the group of non-normal level of plasma LDH than group of normal LDH level(P<0.05).The levels of VEGF and LDH are significantly correlated each other(P<0.01).Conclusion The angiogenesis are important for tumor metastasis in patients of NHL.The serum VEGF can be used as prognosis parameters in patients with NHL.
