Objective To discuss the efficacy and safety of transurethral plasmakinetic resection of the prostate(PKRP) for benign prostatic hyperplasia(BPH).Methods A British made Bipolar plasmakinetic resection system(Gyrus) was employed in this series.Started from the 6 o’clock point,the middle lobe of the prostate was resected,followed by the left and right lobes,which were resected down to the prostate capsule.And then the bladder neck was cut down.The apical tissues were resected to the anterior border of the seminal colliculus.After the operation,a F22 three-channel catheter was indwelled for 3 to 5 days after the operation,and a balloon was place in the bladder neck.Results The procedure was completed successfully in all of the cases with a mean operation time of(85.0?12.0) min,and a median blood loss 115.0 ml(30 to 650).Ten patients received blood transfusion during the operation(200 to 400 ml).No case showed transurethral resection syndrome or obturator nerve reflex.Fourteen patients developed inflammatory stricture of the anterior ureter and was then cured by dilating the urinary tract;15 cases showed transient urinary incontinence and was cured after pelvic floor muscle training for 1 to 3 weeks.Follow-up was available in the patients for 1 to 6 months,during which the mean Qmax of the patients significantly increased compared to that preoperation [from(7.6?2.4) ml/s to(22.6?3.4) ml/s,t=13.582,P=0.000),and the IPSS and life quality score markedly decreased [from 27.3?1.5 and 4.3?0.4 to 7.0?1.2 and 2.1?0.8;t=16.394 and 9.761,P=0.000 and 0.005,respectively] Conclusion PKRP is an effective and safe treatment for BPH.

Objective To investigate the effects of compound lidocaine cream applied to tracheal tube on the recovery of tonsil with adenoidectomy in general anesthesia. Methods 120 patients undergoing elective tonsillectomy with adenoidectomy were randomly divided into the experimental group and the control group. In the experimental group, the surface of the tracheal tube was uniformly coated with compound lidocaine cream before anesthesia. In the control group, paraffin oil was given evenly to the surface of the tracheal tube. The changes of hemodynamics and the incidence of complications in the two groups were observed and recorded. Results The indexes of hemodynamics in the experimental group were more stable than those in the control group, and the control group had poor tube resistance, and the incidence of complications such as cough, irritability and sore throat was increased (P<0.05). Conclusion Application of compound lidocaine cream on tracheal tube surface can effectively reduce the cough and other stress response during the general anesthesia recovery period, decrease postoperative irritability and improve the safety of children after surgery.

Objective In our previous work, the prevalence of anti-endothelial cell antibodies(AECA) in patients with systemic vasculitis and other autoimmune diseases was analyzed. AECA against a 47 000 endothelial cell antigen was found in patients of a variety of systemic vasculitis and systemic lupus erythematosus (SLE). It was suggested to be α-enolase by the combination of immunoblotting and proteomics methods. The aim of this work is to demonstrate that α-enolase is one of the targets of AECA, and to detect the prevalence of anti-α-enolase antibody in sera of patients with autoimmune disorders including systemic vasculitis. Methods The CDS of human Enol gene was amplified by polymerase chain reaction (PCR), with template of human placenta λzap express Cdna library. The product was then recombined with expression vector. After expression and purification from E.coli, the recombinant protein was analyzed by mass spee-trometry. The prevalence of anti-α-enolase antibody in patients with autoimmune disorders including systemic vasculitis was tested by Western blot and enzyme-linked immunosorbent assay (ELISA). Results The CDS of human Enol gene was subcloned to the expression vector. Recombinant human α-enolase was expressed and purified in E.coli. The recombinant protein was demonstrated to be his-tagged human a-enolase by mass spectrometry. Results of Dot-Blot revealed that the prevalence of anti-α-enolase antibody was 76.7% in systemic vasculitis [including 74.0% in Behcet's disease (BD), 81.5% in Takayasu artefitis (TA), 62.5% in Wegener's granulomatosus (WG), 92.3% in microscopic polyangitis (MPA) and 80.0% in Churg-Stranss syndrome (CSS)], 78.3% in SLE, 63.6% in Sjogren's syndrome (SS) and 78.9% in rheumatoid arthritis(RA). No positive signals were detected in sera of normal controls or patients with polymyositis/ dermatomyositis (PM/DM). There was no statistical significance among positive rates of anti-α-enolase antibody in systemic vasculitis, SLE, SS or RA patients. The prevalence of positive signals at the most extensive level (+++～++++) was 51.7% in patients with systemic vasculitis, 33.3% in SLE, 42.9% in SS and 20.0% in RA. There was statistical significant difference between RA and systemic vasculitis. Conclusion The identification of human α-enolase as one of the targets of AECA and its prevalence in a variety of autoimmune disorders will shed some light on the understanding of the pathogenesis of vascular injury in autoimmune diseases.

Objective To observe the expressions of Akt and ERK phosphorylation in abdominal aortic aneurysm of rat model, and explore the pathogenesis of abdominal aortic aneurysm. Methods The rat model of abdominal aortic aneu-rysm was established. The diameter of abdominal aorta was measured and the extended rate of the aorta was calculated. HE staining was used to observe the change of pathology. Immunohistochemistry and Western blot methods were used to detect the expressions of Akt and ERK phosphorylation in the level of protein. Results The dilation of aorta was significantly high-er in abdominal aortic aneurysm group than that of saline group and normal group (P＜0.05). HE staining showed structural disorder and inflammatory cell infiltration in abdominal aortic aneurysm group. The results of immunohistochemistry and Western blot results showed that phosphorylation of Akt expression was significantly higher in abdominal aortic aneurysm group than that of saline group and normal group (P＜0.05). There was no significant difference in phosphorylation of ERK expression between three groups (P>0.05). Conclusion PI3K/Akt signaling pathway may be involved in the development of abdominal aortic aneurysm.

Objective To investigate the efficacies of preoperative location with titanium clip and methylene blue staining in laparoscopic colectomy.Methods The clinical data of 31 patients with colorectal polyps which could not be resected under endoscope were admitted to the Third Affiliated Hospital of Sun Yat-Sen University from August 2006 to September 2012 were retrospectively analyzed.According to the methods of preoperative location of colorectal polyps,all patients were divided into the titanium clip group (18 patients) and the methylene blue group (13 patients).Titanium clip group:enteroscopic and pathological examination were firstly performed,and then 1 or 2 titanium clips were placed at the superior and inferior part of the polyps.After enteroscopic examination,abdominal X ray examination was performed to detect the position of polyps according to the positions of the titanium clips.Methylene blue group:after colonoscopy,methylene blue of 1 mL was injected into the adjacent mucosa of the polyps,and 4 positions around the polyps were selected for the injection of methylene blue.If the 2 locating methods were failed,intraoperative enteroscopy was performed.Laparoscopic resection for intestine or mesenterium was performed according to the treatment principle of colorectal neoplasms,and the location efficacy of the 2 methods and the treatment of the 2 groups were analyzed.The measurement data and the count data were analyzed using the t test and chi-square test,respectively.Results The success rates of the titanium clip group and the methylene blue group were 15/18 and 8/13,with no significant difference between the 2 groups (x2=0.284,P ＞0.05).The polyps in 8 patients which were failed to be localized by titanium clip or methylene blue were localized by intraoperative enteroscopy,while the operation time was prolonged to (44 ± 13)minutes.No positioning errors were detected in all the 31 patients.Laparoscopic right colectomy was performed on 4 patients,laparoscopic left colectomy on 11 patients,laparoscopic sigmoid colectomy on 9 patients,laparoscopic anterior resection of rectum on 7 patients.No morbidity or mortality was detected in the 2 groups.The length of specimen,distance between the proximal margin and the superior margin of the tumor,distance between the distal margin and the inferior margin of the tumor (patients with colonic polyps),distance between the distal margin and the inferior margin of the tumor (patients with high rectal polyps),and the number of lymph node resected were (20 ± 7) cm,(11 ± 4) cm,(8.6 ± 3.1) cm,4.2 ± 1.1,8 ± 5 in the titanium clip group,and (20 ± 5) cm,(9 ± 3) cm,(9.1 ± 2.8) cm,4.6 ± 0.5,7 ± 6 in the methylene blue group,with no significant difference between the 2 groups (t =0.053,0.918,0.213,1.486,0.267,P ＞0.05).Fifteen patients had cancerization of the polyps,including 8 patients with TNM Ⅰ stage,6 with TNM Ⅱ] stage and 1 with TNM Ⅲ stage.Conclusions For patients with colorectal polyps located at the intestine above the descending colon,titanium clip locating is easy,safe and effective,and it could be the first choice for locating the colorectal polyps.Endoscopic methvlene blue staining is simple but high technique demanding.Intraoperative enteroscopy is precise for locating the polyps at the intestine below the descending colon.
