Objective To investigate the efficacy and safety of plasmakinetic enucleation and resection of the prostate by divided into three parts and blocking blood flow in advance (PKERPDPB). Methods 158 patients with BPH were randomly divided two groups: 81 patients treated by plasmakinetic enucleation and resection of the prostate by divided into three parts and blocking blood flow in advance (PKERPDPB), 77 patients treated by plasmakinetic resection of the prostate (PKRP). All patients were evaluated preoperatively and at 1, 6, 12 months after surgery by IPSS, QOL, Qmax and PVR. Operation time, resected adenoma weight, catheterization time, hospital stay and complications were documented. Results There were no significant differences in preoperative parameters. The resected adenoma weight in the PKERPADPB group was heavier than that in the PKRP group, the difference was significant. Compared with PKRP, PKERPDPB required a longer operation time, but resulted in less hemoglobin decrease, less catheterization time and hospital time. During the 1, 6, 12 months of follow-up, there was no significant difference in Qmax, IPSS, PVR and QOL between the groups. Conclusion PKERPDPB was statistically superior to PKRP in blood loss, catheterization time, hospital stay but inferior in operation time. It was a safe and effective treatment for BPH.

Bosentan is a non-selective endothelin receptor antagonist,which plays an important role in the treatment of children with pulmonary arterial hypertension.Bosentan has shown to improve exercise capacity,hemodynamics and reduce pulmonary vascular resistance in pediatric patients.The main adverse effect is less severely comparing with the adult.The combination of bosentan with other drugs can improve the life quality furtherly.Further study of large-scale trials needs focus on the long-effects of bosentan,the ideal period of therapy and the effects of combination therapy in children.

Background and purpose: The prognosis of completely resected stage ⅢA(N2) non-small cell lung cancer (NSCLC) remains a significant concern. The 5-year overall survival (OS) rates range from 10% to 30%. This study aimed to analyze the patterns of first failure in completely resected stage ⅢA(N2) NSCLC and to assess the actuarial risk of developing metastasis at different sites and to guild standard clinical practice. Methods: Patients withⅢA(N2) NSCLC who had undergone radical surgery in our hospital from Jan. 2005 to Jul. 2012 were retrospectively reviewed. The progression-free survival (PFS), the OS, patterns of first failure, the actuarial risk were analyzed. The cumulative incidence of first failure was determined using the Kaplan-Meier analysis. Results: Among 357 patients who met the eligibility criteria with completely resected stage ⅢA(N2) NSCLC, 5-year OS was 36.9%. There were 284 (77.6%) patients experiencing disease failure: 61 with local failure, 197 with local and distant failures, and 26 patients with local recurrence as the first failure. Brain, bone and lung were the main sites of distant failure as the first failure, while brain was the most common site. There were 67 patients developing brain metastases (BM) as the first site of failure. The median time of local failure as the first site of failure was 13.6 months, and the time to develop distant recurrence was 15.1 months. 92.5% BM developed in 3 years after the complete resection. Conclusion: As the first failure, the rate of distant failure was much higher than that of local failure in completely resected stage ⅢA(N2) NSCLC. Brain was the most common site of distant failure as the first failure. These results can be helpful in guiding standard clinical practice and evaluating the outcome of comprehensive treatment.

Objective To observe the effect of emotion regulation on anxiety in patients undergoing functional endoscopic sinus surgery (FESS) under acupuncture-drug compound anesthesia.Method Ninety patients who were going to receive FESS were randomized into group A, B and C, 30 cases in each group. Acupuncture-drug compound anesthesia [electroacupuncture at Yingxiang (LI 20) and Yintang (GV 29)] was adopted in the three groups, ordinary doses of anesthetic drugs for group A and B (1% Tetracaine hydrochloride injection 100 mg+2% Lidocaine hydrochloride injection 0.1 g+Adrenaline hydrochloride injection 2 mL) and reduced doses for group C (1% Tetracaine hydrochloride injection 70 mg+2% Lidocaine hydrochloride injection 0.1 g+Adrenaline hydrochloride injection 2 mL). Conventional nursing was applied to group A, while specific emotion regulation was additionally adopted in group B and C during the perisurgical period. The three groups were evaluated by using Zung's Self-rating Anxiety Scale (SAS) prior to the surgery, 24 h and 48 h after the surgery, and the satisfaction ratings of the patients towards the surgery, anesthesia and nursing were compared.Result The SAS score 48 h after the surgery was significantly different from that before the surgery in group A (P<0.05). The SAS scores 24 h and 48 h after the surgery were significantly different from the score before the surgery in group B and C (P<0.05); the score 48 h after the surgery was significantly lower than that 24 h after the surgery in group B and C (P<0.05). 24 h and 48 h after the surgery, the SAS scores in group B and C were significantly different from those in group A (P<0.05). The satisfaction ratings of nursing in group B and C were significantly higher than the rating in group A (P<0.05). Conclusion Specific emotion regulation can effectively mitigate the anxiety of patients undergoing FESS under acupuncture-drug anesthesia, and improve the satisfaction rate of patients towards nursing.

Objective To investigate the clinical efficacy of inserting a ureteral access sheath under direct view in flexible ureteroscopy with the help of rigid ureteroscope.Methods From March 2013 to July 2015,there were 68 patients accepted a ureteral access sheath in flexible ureteroscopy with the help of rigid ureteroscope for the treatment of kidney stones.There were 46 cases male,22 cases female,aged from 22 to 76 years old,average 43.9 years.There were 68 cases with backaches or hematuria.There were 48 cases with single stone,20 patients with multiple stones.There were 5 cases with stones on both sides.The stone diameter were from 1.2 to 2.5 cm,the average (1.83 ± 0.16) cm.There was no hydronephrosis in 18 cases,mild hydronephrosis 42 cases.The operations were carry out under general anesthesia.By using rigid ureteroscope placed zebra guidewire,then intercept F8 single lumen tip to 1.0 cm section on rigid ureteroscope,was placed into a modified 42 cm ureteral access sheath.Then the modified 42 cm ureteral access sheath was inserted under direct view with the help of rigid ureteroscope.Preoperative patient characteristics,radiographic stone size,operation time,success rate of lithotripsy,serious complications especially ureteral injury was recorded.4 weeks and 12 weeks after operation,ultrasound and/or CT were reexamined to assess the success rate of lithotripsy and the incidence ureteral stricture.Results All the procedures were successful.The operation time was (62.2 ± 6.5)min,the hospital stay was (3.1 ± 0.2) d.The success rate of ureteral access sheath completely placement was 97.1％,partially placement was 2.9％.Postoperative complications included Clavien classification grade Ⅰ 6 cases and grade II 2 cases.The postoperative follow-up averaged (12 ± 1.2) months for all case.The success rate of lithotripsy was 76.5％ in 4 weeks postoperative,and it was 95.6％ in 12 weeks.During the follow-up,compared with the preoperative cases,62 cases were not found to increase the degree of hydronephrosis.There were 58 cases (58/62) without hydronephrosis.4 cases were mild hydronephrosis (4/62).CT showed normal ureter 52 cases (52/52).Conclusions It was safe and reliable procedure with good results.It would be a safe procedure to inserting a ureteral access sheath under direct view in flexible ureteroscopy with the help of rigid ureteroscope.
