Objective To study the changes of the T-lymphocyte subsets in patients with Guillain-Barré syndrome(GBS)before and after intravenous immunoglobulin treatment(IVIG),and to explore the possible mechanism of the IVIG curing GBS further.Methods Chose 31 cases of clinically confirmed GBS were enrolled and compared before and after the treatment.According to the effect of the therapy,31 cases of the total were sub-divided into effective and ineffective groups.Relative counting of peripheral blood T-lymphocyte subsets was preformed with flow cytometry.Results ①The percentage of CD8+ T and CD4+CD29+ T cell was significantly lower(CD8+T:28.77%±11.02% vs 31.84%±12.35%,CD4+CD29+T:56.71%±12.44% vs 62.40%±12.72%,t=2.995,3.919,P＜0.05)after therapy,while the rate of CD4+/CD8+T and the percentage of CD4+CD45RA+T cell increased notably(t=2.368,3.860,P＜0.05);but there was no notable difference in the percentage of CD3+T and CD4+T cell.②The percentage of CD8+T and CD4+CD29+ T cell was significantly lower(t=2.144,3.343,P＜0.05)after the treatment,while the rate of CD4+/CD8+T and the percentage of CD4+CD45RA+T cell increased notably(t=2.159,3.277,P＜0.05)in the good curative effect group,but there was no change in the bad curative effect group.③61.29%(19/31)of the patients significantly improved by IVIG,and there was no death case.Conclusions T-lymphocyte subsets change in a varing degree after IVIG treatment in acute GBS patients,which lays an immunological foundation for the further study of pathogenesis and mechanism of IVIG curing GBS;effective on GBS,IVIG can actively suppress pathogenetic condition and promote the recovery of nrevous function.

Objective To investigate the safety and feasibility of barbed absorbable suture line in retroperitoneoscopic partial nephrectomy. Methods 45 patients who were suitable for retroperitoneoscopic partial nephrectomy from February 2013 to February 2014 were collected and randomly divided into V-Loc group and the control group. 23 cases of V-Loc barbed absorbable suture line were chosen by suture kidney in V-Loc group.There were 22 cases of coated vicryl plus antibacterial suture and Hem-o-lok clip in the control group. The differences of operative time, blood loss, warm ischemia time, suture time, hospital stay and suture material costs were compared respectively between the two groups. Results All 45 cases of retroperitoneoscopic partial nephrectomy were successfully performed, without conversion to open surgery and important intraoperative complications. Postoperative pathology report showed that there were 37 cases with renal clear cell carcinoma, 3 cases with papillary renal cell carcinoma, 2 cases with chromophobe renal cell carcinoma with negative surgical margin, 3 cases with renal angiomyolipomas. In the V-Loc group and the control group, the average operative time were (90.8±9.6) and (96.9±9.1) min (P>0.05), the mean blood loss were (80.4±24.2) and (99.5±24.8) ml (P>0.05), the mean warm ischemia time were (21.5±3.4) and (25.3±1.9) min (P<0.05), suture time were (10.8±1.7) and (16.8±3.1) min (P<0.05), respectively, postoperative hospital stay were (5.7±1.7) and (7.1±1.9) d (P>0.05), the average cost of renal parenchymal suture material were (1 215.5±101.4) and (2 073.5±301.8) yuan (P<0.05). The warm ischemia time,suture time and suture material costs in the V-Loc group were significantly lower than those in the control group (all P<0.05). Conclusion The application of barbed absorbable suture line in retroperitoneoscopic partial nephrectomy can shorten warm ischemia time and suture time, and save hospitalization costs, with favorable safety and feasibility.

Objective To evaluate the efficacy of preoperative and postoperative intravesical instillation of pirarubicin for the prevention of postoperative recurrence of non-muscle invasive bladder cancer (NMIBC). Methods From September 2012 to March 2014, 120 patients who were diagnosed as NMIBC and accepted trans-urethral resection of bladder tumor (TUR-Bt) were collected and randomly divided into two groups, including treatment group (60 cases) and control group (60 cases). 30 minutes before the operation, instillation of pirarubicin (40 mg) was performed in the treatment group, then pirarubicin perfusion was given within 24 h after operation, once a week for 8 weeks, and once a month for 10 months after operation. In control group, instillation of pirarubicin (40 mg) was given within 24 h after operation, and other treatments were the same as the treatment group. The differences of lesion detection probability, the 2-year recurrent rate and the adverse reaction rate were compared between the two groups. Results The lesion detection rates were 42.70 % (38/89) and 1.85 % (2/108) in the treatment group and control group, respectively (χ2=50.303, P<0.05). 119 patients were follow-up for 24 months. The 2-year recurrence rates were 8.47%(5/59), 21.67% (13/60) in treatment group and control group respectively (χ2= 4.033, P< 0.05). The adverse reactions mainly included hematuria (3 cases in treatment group, 3 cases in control group), urinary tract irritation (3 cases in treatment group, 2 cases in control group) and urethral stricture (1 case in treatment group, 1 case in control group). The difference of the adverse reaction incidence between the two groups was not significant statistically [11.86 % (7/59) vs. 10.00 (6/60), χ 2 = 0.106, P > 0.05]. Conclusions The preoperational intravesical instillation of pirarubicin can fix and diagnose malignant lesions in the bladder without adverse reactions, which will improve the rate of tumor resection and prevent postoperative recurrence of tumors.
