ABSTRACT
Objective To investigate the safety and efficacy of Pipeline embolization device (PED) for the treatment of complex middle cerebral artery aneurysms. Methods From December 2015 to June 2018, 7 patients with complex middle cerebral artery unruptured aneurysms and treated with PED at the Department of Neurosurgery, the Second Affiliated Hospital of Nanchang University were recruited. The clinical and follow-up data were analyzed. The Kamran classification was used to evaluate the immediate effect of aneurysm embolization and the changes of parent artery. At 6 months after operation, the effect of embolization was evaluated by Raymond grading; the modified Rankin scale (mRS) was used to evaluate prognosis: 0 -2 for good prognosis, 3 -6 for poor prognosis, and 6 for death. Results The 7 patients with complex middle cerebral artery aneurysms were successfully treated with one PED, including 2 patients with single PED and 5 combined with coiling. Digital subtraction angiography (DSA) were performed immediately after PED implantation. All had Kamran classification 2a at immediate angiography after embolization. The postoperative mRS score was 0 in 6 patients and 1 in 1 patient. One patient with M1 aneurysm had acute in-stent thrombosis and another one with M1 aneurysm had mini-focal occipital lobe cerebral infarction. All 7 patients were Raymond classification I during postoperative follow-up from 6 to 12 months. Among them, 6 patients had aneurysms total occlusion with patent parent artery. For the remaining one patient, the aneurysm was found slightly residual at the middle cerebral artery bifurcation but was totally occluded with parental artery patent at 12 months. There were no aneurysmal rupture, cerebral parenchymal hemorrhage, and neurological defects in the 7 patients during intraoperative and postoperative follow-up periods (6 to 18 months). Conclusions Embolization of complex cerebral artery aneurysms with PED is effective and safe, but its long-term effect still needs to be validated by longer follow-up results and large sample-sized trials.
ABSTRACT
Objective To investigate the efficacy and safety of intravesical instillation with Sufuning (SFN) lotion for prevention of postoperative recurrence of bladder cancer. Methods A total of 240 bladder cancer patients who were diagnosed as bladder cancer and accepted trans-urethral resection of bladder tumor from January 2010 to June 2016 in Shanxi Provincial Cancer Hospital were randomly divided into the experimental group (120 cases) and the control group (120 cases) according to the envelope method. The patients in the experimental group were treated with SFN lotion for immediate intravesical instillation(250 mg for once), and the patients in the control group were treated with pirarubicin (THP) for immediate intravesical instillation (30 mg for once). The patients of two groups were treated with intravesical chemotherapy once a week for 8 times, and the chemotherapy was performed once a month for 1 year. The recurrence rate, progression-free survival (PFS) rate, overall survival (OS) rate and recent side effects were compared between the two groups. Results The patients were followed up for 6 to 60 months. The median follow-up time was 36.5 months.In the experimental group,6 patients were lost and 8 patients were lost in the control group.The experimental group, the total recurrence rate was 26.3 % (30/114). The control group, the overall recurrence rate was 25.0 % (28/112) (χ2= 0.142, P = 0.781). Five years of PFS rate in the experimental group and the control group was 73.7 % (84/114) and 75.0 % (84/112) respectively, and there was no significant difference between the two groups (χ2= 2.011, P= 0.615). Five years of OS rate in the experimental group and the control group was 95.6 % and 92.9 % respectively, and there was no significant difference between the two groups (χ 2= 1.611, P= 0.425). The major side effects included chemical cystitis and hematuria. The incidence of chemical cystitis and hematuria in the experimental group was significantly lower than that in the control group(χ2=5.991,P=0.018;χ2=4.925,P=0.036).There was a statistically significant difference of the hematological side effects (blood routine changes) between the two groups (χ 2= 4.891, P= 0.032). Conclusion It is safe and effective for intravesical instillation of SFN lotion to prevent the recurrence of bladder cancer.
ABSTRACT
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]. 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.

ABSTRACT
Objective To evaluate the efficacy and feasibility of 125I radioactive seed interstitial implantation for the local advanced urinary tract epithelial carcinoma without total resection.Methods The clinical data of 21 patients with local advanced urothelial carcinoma without completely surgical resection who were treated by 125I radioactive particles implantation were retrospectively analyzed.The patients were divided into two groups and received preoperative plan.In group A, 14 patients received implants during operations, including 7 bladder transitional cell carcinoma patients who underwent a transurethral resection surgery or partial bladder resection and another 7 ureteral carcinoma cases who underwent semi urine road resection.After these operations, all of patients had tumor residues.After furthest resection of the tumor, the 125I seeds were implanted at the residual suspicious tumors and their surroundings.In group B, 7 patients were implanted under the guidance of color ultrasound or CT.According to the evaluation criteria of solid tumor in 2009, the tumor remission rate, survival rate, distribution and the mobile information of the particles were observed.Results The operations were successfully completed in all of 21 patients, and serious complications did not appear during the operation.Particle distribution and lesions were basic coincidence.A total of 2 particles displaced, but every patient had no adverse reactions.There were 2 patients with local fever after operation within 4 months, while the rest of patients had no adverse reactions.After median follow-up for 36 months (3-75 months) , the 1-year survival rate was 100.0 ％ (21/21), the 2-year survival rate was 90.5 ％ (19/21), and the 3-year survival rate was 61.9 ％ (13/21).The tumor remission rate of group A was 85.7 ％ (12/14) after 6-9 months, and was 42.9 ％ (6/14) after 12 months.The bladder was preserved in 7 cases with bladder tumors with the 2-year survival rate of 100.0 ％ (7/7) and the 5-year survival rate of 71.4 ％ (5/7).The tumor remission rate of group B after 6-9 months was 71.4 ％ (5/7), and was 42.9 ％ (3/7) after 12 months.Conclusion 125I seed implantation is a good choice for locally advanced urothelial carcinoma with high local tumor control rate, which is expected to be applied in the individual treatment of advanced urothelial cancer.
ABSTRACT
Objective To observe the difference in therapeutic efficacy between acupuncture with distant acupoints selection and proximal acupoints selection in treating acute headache.Method Sixty patients with acute headache were randomized into group A and group B, 30 cases in each group. Group A was intervened by acupuncture with distant acupoints selection, while group B was by acupoints with topical acupoints selection. The Visual Analogue Scale (VAS) and Present Pain Intensity (PPI) from McGill Pain Questionnaire (MPQ) were observed before and after intervention, and the clinical efficacies were compared between the two groups. Result After treatment, the VAS and PPI scores were significantly different from that before treatment in both groups (P<0.01). The changes of VAS and PPI scores in group A after intervention were significantly different from that in group B (P<0.01). The total effective rate was 90.0% in group A versus 73.3% in group B, and the difference was statistically significant (P<0.01). Conclusion Acupuncture with distant acupoints selection can produce a better therapeutic efficacy than acupuncture with topical acupoints selection.
ABSTRACT
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 (P0.05), 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.
