0.05).There was a positive correlation between the tempo of the engraftment and the progressive increase of the doses of MNC in the range of (3～5.99)?108/kg,but which was not found in the range of 6?108/kg.Conclusion These results indicate that MNC taken as an index for the measurement of the hematopoietic stem cell/progenitor content can reliably predict hematopoietic reconstitution after both HLA-matched and-mismatched sibling donor peripheral blood stem cell transplantation,with the rate and tempo of engraftment comparable with that in CD34+ cell group,and however,the target dose was reached with one apheresis in all 83 donors in MNC group(100%),as compared with 14 donors in CD34+ cell group(37.84%),suggesting that MNC may replace CD34+ cell as an independent index for the assessment of the stem cell/progenitor content in clinical practice.

Objective To investigate the value of DNA-image cyt-ometry (DNA-ICM) in the diagnosis of urothelial cell carcinomas (UCC). Methods Totally 162 voided urine specimens (92 cases from urothel-ial car-cinomas patients and 70 cases from benign urinary system diseases patients ) were detected with DNA-ICM and liquid-based cytology (LBC), respectively. Results The sensitivity and specificity of DNA-ICM were 65.2%and 100% respectively in the diagnosis of UCC but those of LBC were 27.2% and 98.6%, respectively. The sensitivity of DNA-ICM was significantly higher than that of LBC in the diagnosis of UCC (P < 0.01). The sen-sitivity of DNA-ICM in upper urinary tract urothelial cell carcinomas (UTUC) were 77.1%, which was much higher than that in bladder urothelial cell carcinomas (57.9%) but no statistical significance was found (P >0.01). Conclusion DNA-ICM, which improves the positive rate of urinary cytology, has great application value in the diagnosis of urothelial cell carcinomas and it is an effective screening method for urothelial cancer in diag-nosis and follow-up.

Objective To evaluate the impact of low-dose 131I therapy and high-dose 131I therapy on the clinical outcome in PTC patients coexisting with Hashimoto's thyroiditis (HT).Methods A total of 140 non-distant metastatic PTC patients (16 males,124 females,age range:16-66 years) from July 2010 to December 2014 were enrolled in this retrospective study.Patients concurrent with HT (n=84,group A) were divided into low-dose group (1 110 MBq,n=56,group A1) and high-dose group (5 550 MBq,n=28,group A2) according to 131I ablation dose.Patients without HT (n =56) were enrolled as control group (group B),and received 1 110 MBq of 131I.The thyroid remnant ablation outcome was evaluated according to 131I diagnostic whole-body scan (Dx-WBS),neck ultrasonography (US),serum Tg and TgAb level 6-8 months after 131I ablation therapy.The successful ablation rates were compared by x2 test.Kruskal-Wallis rank sum test was also used.Results There were no significant differences among the 3 groups in terms of both clinicopathological features and postoperative remnant thyroid (H:0.203-2.944,x2:0.271-0.970,all P＞0.05).When negative Dx-WBS and US were deemed as successful ablation criterion,complete ablation rate was found significantly more in group B (94.6％,53/56) than that in group A1 (82.1％,46/56;x2=4.264,P＜0.05),but no significant difference was found between group A2 (85.7％,24/28) and group A1 (x2 =0.318,P＞0.05).When combining negative sTg (sTg＜1 μg/L,TgAb＜46 kU/L) with the above 2 criterions to assess remnant ablation outcome,group B also had a higher successful rate to achieve complete ablation (85.7％,48/56) compared with group A1 (75.6％,34/45),but without statistical significance (x2=2.978,P＞0.05),and no difference was observed between group A2 (12/15) and group A1 (x2=1.320,P＞ 0.05).Conclusion Non-distant metastatic PTC patients coexisting with HT has undesirable 131I ablation outcome compared with those without HT,increasing 131I dose is unhelpful to enhance efficiency of remnant ablation for PTC patients with HT.

OBJECTIVETo compare the effect of transurethral resection of the prostate combined with endocrine therapy (TURP + ET) with that of αlA-blockers combined with ET ((αlA-b + ET) in the treatment of bladder outlet obstruction (BOO) in patients with advanced prostate cancer (PCa), and to investigate the safety of the TURP + ET for the treatment of PCa with BOO.

METHODSWe retrospectively analyzed 63 cases of PCa with BOO, 28 treated by αlA-b + ET and the other 35 by TURP + ET. We obtained the residual urine volume (RV), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and quality of life score (QoL) before and after treatment along with the overall survival rate of the patients, followed by comparison of the parameters between the two methods.

RESULTSAt 3 months after treatment, RV, IPSS, and QoL in the TURP + ET group were significantly decreased from (137.8 ± 27.6) ml, (22.3 ± 3.6), and (4.2 ± 0.8) to (29 ± 13.6) ml, (7.8 ± 2.1), and (1.6 ± 0.5) respectively (P < 0.05), while Qmax increased from (5.6 ± 2.1) ml/s to (17.6 ± 2.7) ml/s (P < 0.05); the former three parameters in the αlA-b + ET group decreased from (133.6 ± 24.9) ml, (21.5 ± 3.2), and (4.7 ± 1.1) to (42 ± 18.3) ml, (12.8 ± 2.6), and (2.5 ± 0.7) respectively (P < 0.05), while the latter one increased from (6.3 ± 2.4) ml/s to (11.7 ± 2.3) ml/s (P < 0.05), all with statistically significant differences between the two groups (P < 0.05). The overall survival rate of the TURP + ET group was not significantly different from that of the αlA-b + ET group (51.4% vs 46.4% , P > 0.05).

CONCLUSIONTURP + ET is preferable to αlA-b + ET for its advantage of relieving BOO symptoms in advanced PCa without affecting the overall survival rate of the patients.

Objective: To construct a polycistron tandem repeated Echistatin (Ecs) gene. Methods: Three Ecs genes with independent initiation and termination codon were ligated tandem through restriction enzyme sites after amplified with 3 pairs of primers using pMD18T-Ecs as template. The polycistron Ecs gene was inserted into pET30a and expressed in E.coli BL21(DE3) with IPTG induction. The expression results were identified by 18% SDS-PAGE and Western blot. Results: The expression of Ecs polycistron was accomplished with 18% expression level of total protein determined by SDS-PAGE and Western blot. Conclusion: The successful expression of Ecs polycistron provided a new method for the preparation of low molecular weight protein.

Objective To investigate the safety,diagnostic value and clinical impact of double balloon enteroscope (DBE) in elderly patients (aged ≥75 years).Methods Clinical data and DBE findings of elderly patients in the Department of Gastroenterology in Remin Hospital of Wuhan University from January 2010 to January 2013 were retrospectively analyzed and compared with those of younger patients.Results The diagnostic rate,complication rate and clinical impact rate were 69.0％ (29/42),0％ (0/42) and 76.2％ (32/42) in elderly patients.There were no statistically significant differences on those parameters between elderly patients and younger patients (all P＞0.05).For elderly patients,the leading causes of obscure gastrointestinal bleeding (OGIB) were tumor (30.0 ％,9/30) and ulcer (16.7 ％,5/30),while angiectasis (6.7 ％,2/30) was uncommon.Conclusions DBE is an effective and safe method for diagnosis of small bowel disease in elderly patients.Tumor is the most common cause of OGIB,while angiectasis was uncommon.

Objective To observe the effect of somatostatin (SST) on the expression of metalloproteinase-2(MMP-2) and tissue inhibitor matrix metalloproteinase-2(TIMP-2) of implanted tumor in nude mice after partial hepatectomy.Method Nude mice were divided into group A(n=10) implanted by human hepatocellular carcinoma(HCC),group B(n=10, partial hepatectomy) and C(n=10,HCC implantation after liver resection). SST(250 ?g/kg,b.i.d) was given intraperitoneally in group C. Mice were sacrificed on 35th d, tumor was measured, the expression of MVD.MMP-2 and TIMP-2 was detected by immunochemical staining and quantitative image computer-analysis. Results In group B, the weight and volume and expression of MVD.MMP-2 of tumor tissue was markedly incressed than in group A(P
