To establish a murine carotid artery transplantation model for the study of the chronic rejection, 80 rats were divided into two groups, an allotransplant (ACI-Lewis) group and an isotransplant (Lewis-Lewis) group (control group). The donor carotid artery and the recipient carotid artery were anastomosed by using a polyethylene cuff (internal diameter: 0.7 mm, length: 3 mm).The pathological changes of carotid artery transplant were observed 14, 28 and 56 days after the transplantation. The results showed that the model was successfully established in 95% of the animals. The chronic rejection-associated arteriosclerosis was induced 28 days after the transplantation. The new chronic rejection model of carotid artery by using cuff technique caused fewer traumas and was easy to make. The pathological changes of the transplant mimicked the chronic rejection-associated arteriosclerosis found in human transplant.

Objective To compare the prognosis and life quality of patients with early-stage breast cancer(stage I or II)undergoing breast-conserving surgery or modified radical mastectomy.Methods 180 cases with early-stage breast cancer were divided into 2 groups:breast-conserving surgery group(BCS)and modified radical mastcctomy group(MRM),with 90 cases in each group.The 2 groups were all given radiotherapy,chemotherapy and endocrine therapy according to indications.The prognosis and life quality in the 2 groups were compared.Results The 5-year-postoperative follow-up showed there was no significant difference in duration of disease-free survival(DFS)of the 2 groups.However,life quality of BCS patients was significantly better than that of MRM patients in terms of general health,physical function,pain,vitality,social functioning,emotion and mental health.Conclusion Breast-conserving surgery is highly recommended for patients with early-stage breast cancer.

ObjectiveTo investigate the serum prostate-specific antigen (tPSA),serum free PSA to total PSA ratio (f/tPSA),prostate volume (PV) and prostate-specific antigen density (PSAD) in early prostate cancer (PCa) diagnosis.MethodsRetrospective analysis was performed on serum PSA values and related test results from 252 cases of BPH patients and 49 patients with PCa.Prostate volume (PV) was measured by transrectal ultrasound (TRUS),and the f/tPSAand PSAD values were calculated.The differences of serum tPSA,f/tPSA,PV,and PSAD between BPH and PCa group were compared,the area under the ROC curve was used to evaluate these four indicators for its diagnostic sensitivity and diagnostic specificity.ResultsThe values of tPSA,PSAD in PCa group were significantly higher than BPH group ( P ＜0.05),while the values of f/tPSA,PV in PCa group were significantly lower than BPH group ( P ＜0.01orP ＜0.05).The ROC area showed that serum tPSA(0.8013),f/tPSA(0.7390),PV(0.5613) had lower diagnosis value than PSAD(0.9214) in early prostate cancer ( PSAD ＞ tPSA ＞ f/tPSA ＞ PV).When the upper limit of normal PSA was set to take 4ng/ml,the sensitivity was 91.49％,diagnostic specificity was 51.05％.When the f/tPSA threshold set to 0.16,the diagnostic sensitivity was 57.78％,diagnostic specificity was 78.72％.When PSAD threshold was set to 0.15,diagnostic sensitivity was 88.24％,diagnostic specificity was 81.52％.ConclusionsPSA,f/tPSA and PSAD are indicators for biopsy or followup in early diagnosis of prostate cancer.In particular,the diagnostic value of PSAD has higher sensitivity and specificity than PSA and f/tPSA in the diagnosis of prostate cancer.

Objective: To explore the reasonable compatibility of anesthetics in painless small intestinal endoscopy by comparing the influence of different target plasma propofol concentrations combined with remifentanil on anesthesia effects and respiratory and circulatory functions.Methods: Two hundred patients requiring small intestinal endoscopy were randomly divided into 4 groups,Group Ⅰ given 1% propofol only,with the target plasma propofol concentration set at 4.5 ?g/ml,and Group Ⅱ,Ⅲ and Ⅳ receiving 30-second injection of remifentanil(0.3 ?g/kg) 1 min before target-controlled infusion(TCI) of propofol,with the target plasma propofol concentration set at 3.0,3.5 and 4.0 ?g/ml,respectively.The mean arterial pressure(MAP),heart rate(HR),pulse oxygenation(SpO2),induction time,awakening time,orientation recovery time and the incidence of patients' body motion were observed before anesthesia,at the vanishment of the eyelash reflex,while the small intestine endoscope passing through the Treitz ligament or ileoceal valve and after endoscopy.Results: Compared with baseline values,MAP and HR were significantly decreased in all groups when the eyelash reflex vanished,markedly increased in Group Ⅰ,although not so obvious in Groups Ⅱ and Ⅲ,when the small intestinal endoscope passed through the Treitz ligament or ileoceal valve,and greatly reduced at all time points in Group Ⅳ,with difficult entrance of the small intestine endoscope due to low tension of the intestinal cavity.Comparatively,the induction time was shorter and the awakening time and orientation recovery time were longer in Group Ⅰ,the total dose of propofol and the incidence of body motion notably decreased in Groups Ⅱand Ⅲ,and the incidence of respiratory depression obviously increased in Group Ⅳ.Conclusion: Propofol TCI combined with remifentanil can be used safely and effectively in painless small intestinal endoscopy.Target plasma propofol concentration(3.5 ?g/ml) in combination with remifentanil(0.3 ?g/kg) gives more efficient anesthesia,lower incidence of body motion and respiratory suppression and better recovery.Therefore,it is the suitable anesthetic compatibility in painless small intestinal endoscopy.

Objective To investigate the specific humoral immune response and cellular immune response induced by DNA vaccine with Neisseria gonorrhoeae porin B (PorB) fused with B subunit of Escherichia coli heat-labile enterotoxin B (LTB) in mice. Methods Target genes of porB, ltB and ltB-porB were amplified by polymerase chain reaction (PCR) and cloned into eukaryotic vector pcDNA3.1(-). The recombinants were identified by PCR, enzyme digestion and DNA sequencing.The vectors were transfected into Hela cells, and expressed proteins were checked by cytoimmunofluorescence. Female BALB/c mice were intranasally immunized with recombination vectors. The humoral immune response and cellular immune response were detected by enzyme linked immunosorbent assay (ELISA) and methyl thiazolyl tetrazolium (MTT) colorimetric assay. The expressions of recombination vectors in intranasal mucosal tissues of the immunized mice were detected by immunohistochemistry. The means between groups were compared by analysis of variance. Results All the three recombinants were expressed in Hela cells and intranasal mucosal tissues. The PorB specific IgG in serum and sIgA in vaginal secretions in DNA vaccine immunized mice were significantly higher than those in controls (P＜0.01 ; P＜0.05). Moreover, the sIgA level in pcDNA3.1 (-)/ltB-porB group was higher than that in peDNA3, 1(-)/porB group (P＝0. 002). The levels of interferon-gamma (IFN-γ) and interleukin-4 (IL-4) in the supernatants and stimulation index (SI) of spleen lymphocyte culture in pcDNA3, 1(-)/porB group were (170.04±23.89) pg/mL, (114.68±14.27) pg/mL and 1. 68±0.19, respectively; and those in pcDNA3, 1(-)/ltB-porB group were (161.42±27.50) pg/mL, (124.16±19.04) pg/mL and 1.73±0.28, respectively; which were both higher than those in pcDNA3.1(-)/ phosphate buffered saliae (PBS) group (P＜0. 01; P＜0.05) and pcDNA3.1 (-)/ltB group (all P＜0.05), while there was no significant difference between pcDNA3.1 (-)/ltB-porB group and pcDNA3. 1 (-)/porB group (0. 998, 0. 696, 0. 994; all P＞0.05). Conclusions The constructed DNA vaccines are all successfully expressed in Hela cells and murine intranasal mucosal tissues. The mucosal immunization of the vaccines [pcDNA3. 1 (- )/porB and pcDNA3.1 ( -)/ltBporB] could induce humoral immune response and cellular immune response, especially mucosal immune response. It is confirmed that mucosal adjuvant LTB could promote PorB to induce higher level of mucosal immune response in mice.
