Objective To report the clinical observation and nursing points for recurrent or refractory and aggressive non-Hodgkin's lymphoma treated with MINE regimen. Methods Patients (46 cases) with recurrent or refractory and aggressive non-Hodgkin's lymphoma were given mental nursing,preparation and evaluation of the condition of patients before chemotherapy. Complications especially extravasation of infusion fluid should be prevented during chemotherapy and myelosuppression and long-term complications should be prevented after treatment. Results No patient died after treatment but several complications such as infection(14 cases), nausea and vomiting (grade Ⅰ~Ⅱ, 22 cases, grade Ⅲ,2 cases), alopecia (grade Ⅰ~Ⅱ, 27 cases), mucositis (grade Ⅰ~Ⅱ, 4 cases), liver function lesion (grade Ⅱ, 1 case) were found and improved after proper treatment. No nephrotoxicity and hemorrhagic cystitis were found. Conclusions Selective mental nursing,proper chemotherapy preparation,evaluation of patients' condidtion and positively prevention of chemotherapy-related complications could increase the chemotherapy effect of patients with recurrent or refractory and aggressive non-Hodgkin's lymphoma.

Objective To investigate the expression of Dickkopf-3 (Dkk-3) in esophageal cancer and normal esophageal tissue and the relationship between Dkk-3 expression and the biological behaveior of esophageal cancer. Methods Immunohistochemical method of S-P was used to examine Dkk-3 expression in 69 cases of esophageal squamous cell carcinoma and 5 cases of normal esophageal tissue with non-tumor tissue microarray and the results were analyzed and correlated with their clinical and pathological features. Results Positive Dkk-3 expression was observed in 65.7% (44/67) of the esophageal squamous cell carcinoma cases, but only one of the five cases with normal esophageal tissue showed positive microvascular expression of Dkk-3. In cases with positive expression of Dkk-3 significant differences were found in fiber membrane infiltration, depth of invasion, lymph node metastasis and TNM staging (P < 0. 05), while no significant differences were found in the age, gender and pathological grading (P > 0. 05). Conclusions The upregnlation of Dkk-3 expression in esophageal squamous cell carcinoma may contribute to tumor invasion and metastasis.

OBJECTIVE:
To investigate the psychological statuses of Chinese adults with moderate-to-severe persistent allergic rhinitis, and evaluate the effects of nasal symptoms on their psychological statuseses.
METHOD:
The Symptom Checklist-90 (SCL-90) or self-reporting Inventory was employed to analyze the psychological statuses of 539 adults with moderate-to-severe persistent allergic rhinitis.
RESULT:
The SCL-90 scores of the adults with moderate-to-severe persistent allergic rhinitis were statistically higher than those of non-allergic adults in terms of somatization, depression, anxiety and hostility. No statistical discrepancies existed in gender or age. The course of disease contributed to somatization and compulsion. The effects of nasal symptoms included two aspects: nasal obstruction had a conspicuous impact on somatization, compulsion, interpersonal sensitivity, depression, anxiety and psychosis, while nasal itching contributed to somatization, depression and anxiety.
CONCLUSION
The psychological statuses of adults with moderate-to-severe persistent allergic rhinitis is evidently worse than that of non-allergic adults. Symptoms such as nasal obstruction and itching had an obvious impact on outpatients' psychological statuses.

Objective To investigate the role of outer membrane protein in clinical isolated car-bapenem resistance Acinetobacter baumannii. Methods Carbapenem resistance and sensitive strains were collected from the same patient. After MIST and REP-PCR analysis, carbapenemases were detected by isoe-lectric focusing. Different expressed membrane proteins were identified by two-dimension electrophoresis and mass spectrometry analysis. We also used efflux pump inhibitor PAβN(Phe-Arg-β-naphthylamide) to con-firm the phenotype. Results Carbapenem resistance and sensitive strains were attributed to the same pat-tern. At positions of P17.6 and P19.0, two β-lactamases were expressed in two investigated strains, no cabapenemases were detected. Six differential expressed membrane proteins were identified, a 34 × 10~3 membrane protein that was confirmed by efflux pump inhibitor PAβN experiment (imiponem MIC decreased from far above 32 μg/ml to 8μ/ml) and OprD and CarO. Conclusion Up-regulation of exported protein accompanied with down-regulation of OprD and CarO other than carbaponemases are responsible for carbap-enem resistance in A. baumannii.

Objective To evaluate the clinical experience of applying the combined tacrolimus (FK506) and mycophenolate mofetil (MMF) in simultaneous pancreas and kidney transplantation (SPKT) with bladder drainage of pancreatic secretion. Methods SPKT was performed for 14 consecutive patients. On the first day after transplantation, triple immunosuppression therapy was appliedwith FK506(0.07-0. 15 mg·kg-1·d-1), MMF(1.0- 1.5 g/d) and prednisone (25 mg/d). The FKS06 blood concentration after oral administration was assayed by the means of MEIA. The occurrence of rejection and the drug toxicity were monitored and recorded. Results Nine recipients survived with the grafts and their general conditions were well. They were followed up for 18--70 months (mean 34 months). There was no early stage complication such as pancreatic fistula and thrombosis after operation. The blood glucose level returned to normal range after operation. All recipients survived over 1 year. Of them, 3 cases survived for 1-3 years,1 case survived for 3-4 years, 1 case survived 4-5 years and 4 cases survived over 5 years. All the cases had normal blood glucose level and early graft function. Removal of allograft pancreas was performed on one patient because of hyperacute rejection. There were 4 cases died. Of whom, one case was diagnosed with duodenal stump leak 45 days after transplantation and he died of corrosive hemorrhage 7 months after operation. One patient died of unexpected heart disease. The 3rd patient died ol multiple organ failure and the fourth case died of acute rejection. Four cases with acute rejection, 2 cases with renal toxicity and 1 case with hepatotoxicity were observed. Conclusions The combination of TAC/MMF has synergetic effect. The application of this combination has good immunosuppression result. It could effectively reduce the risk of acute rejection and improve graft survival in SPKT recipients.

BACKGROUND: Following renal transplantation, native renal pelvic or ureteral tumor occurs not only on one side, but also on both sides simultaneously or continuously.OBJECTIVE: To describe a new procedure in managing native renal pelvic or ureteral tumor, in which, retroperitoneal laparoscopic nephroureterectomy was first done followed by transurethral resection of ureteral orifice, and finally the kidney and the complete ureter with a bladder cuff were taken out through a midline abdomen incision, and to validate its feasibility.DESIGN, TIME AND SETTING: A technique modification experiment was performed at the Department of Urinary Surgery, Third Hospital, Peking University between July 2004 and March 2006.PARTICIPANTS: Eight patients (7 males and 1 female) with native renal pelvic or ureteral tumor who received laparoscopic nephroureterectomy with bladder cuff resection were included into this study. Of them, 4 cases had bilateral lesions. Laparoscopic nephroureterectomy with bladder cuff resection was conducted 12 times totally.METHODS: Retroperitoneal laparoscopic nephroureterectomy was first done in the lateral decubitus, followed by transurethral resection of the ureteral orifice with resectoscope in the lithotomy position, and finally, an incision was created in the lower midline abdomen to allow dissection of the distal ureter and bladder cuff and intact specimen extraction. Postoperatively, intravesical chemotherapy was routinely performed to prevent tumor recurrence. The patients were followed up at 3, 6, and 12 months after surgery, and once a year thereafter.MAIN OUTCOME MEASURES: Surgery time, blood loss volume, pathological report, tumor recurrence time, tumor-free survival time, and complications.RESULTS: The mean surgery time was 3.8 hours (range: 2.5-7 hours). The mean hemorrhage volume was 240 mL (range: 50-1 200 mL). Two cases needed blood transfusion, 600 and 1 000 mL, respectively. Transitional cell carcinoma grade Ⅲ was found in 3 cases, grade Ⅱ in 4 cases, and grade Ⅰ-Ⅱ in 4 cases. In addition, there was 1 case presenting with tumor breaking through the serous membrane of the ureter and 1 case suffering from poorly differentiated adenocarcinoma. The tumor recurred locally in one case 6 months after surgery, and the remaining cases all survived in a tumor-free state.CONCLUSION: After renal transplantation, laparoscopic nephroureterectomy with bladder cuff resection through a lower midline abdomen incision is feasible for treatment of native renal pelvic or ureteral tumor, with low tumor recurrence rate and satisfactory excision effects.

Objective To establish a reverse transcription nested polymerase chain reaction ( RT-nPCR ) assay for detection of tree shrews orthoreovirus (TRV).Methods Three strains of TRV were respectively isolated from fresh feces of three tree shrews that came from the same field at different times .We designed and synthesized two pairs of MRV L1 gene nested primers and established the system of RT-nPCR.The TRV RNA was extracted and reversely transcribed to cDNA as a template for nested-PCR amplification.The developed RT-nPCR was optimized.The specificity and sensitivity were tested.Finally, the RT-nPCR was used to detect TRV in 25 tree shrew samples.Results Taking the genomic RNA of TRV as template, the RT-nPCR was able to amplify a specific fragment band targeting the L 1 gene, while there were no target bands in the normal cell control , ( Wa strain rotavirus , hepatitis A virus , and herpes simplex virus ) .The RNA of TRV was diluted by 1:10 to 1:109 .Each dilution sample was analyzed by the RT-nPCR.The minimum detectable concentration of RNA was 0.01 pg/μL.The results of RT-nPCR detection showed that 4 of the 15 tree shrews were TRV-positive in the survival group , and 10 of 10 tree shrews were TRV-positive in the death group . Conclusions The RT-nRCR assay established in this study is accurate , specific and sensitive .Therefore, it can be used for routine detection of TRV in quality assurance testing .

We retrospectively analyzed the clinical data of 615 recipients (347 male and 268 female, age range: 9-75 years weighing 38-100 kg) who received renal transplantation in the Third Hospital of Peking University from January 2001 to July 200 to summarize the causes and experience of surgical complications after renal transplantation. Kidney of donors with brain death wa obtained using modified in situ hypothermy perfusion method, and kidney from living bodies was obtained using posterio abdominal cavity open or abdominal speculum method. After renal transplantation, the immunosuppressive therapy including FK50 or Cyclosporine A + mycophenolate mofetial or mizoribine + Prednisone was applied and regulated according to the variation o concentration in whole blood. Recipients were followed up for at 1 year. Of 615 patients, 29 cases developed surgical complication with the incidence rate of 4.72%; Graft lost in 5 cases due to surgical complications after renal transplantation. The achievement rati of operation was 99.19%.
