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.

Objective To assess the effect of thoracoscopic surgery under laryngeal mask anesthesia and explore the nursing strategies. Methods Thirty-five patients from April to December in 2014 undergoing video-assisted thoracoscopic surgery (VATS) were given intubation anesthesia and another thirty-five ones undergoing the same surgery in 2015 received laryngeal mask anesthesia. The two groups were compared in terms of surgery conditions, surgery complication and ambulation time. Results No significant differences were found in surgery time or blood loss between two groups (P>0.05). The postoperative waking time in the mask anesthesia group was significantly shorter than that of the intubation anesthesia group (P<0.05), and ambulation time was significantly shortened (P<0.05). The rates of throat discomfort, hoarseness and gastrointestinal reactions were significantly lower. Conclusions Laryngeal mask anesthesia used in small thoracoscopic surgery for airway management is safe and feasible. Combined with training in respiration and limb function, better analgesia and nursing, it can keep away complications related to intubation anesthesia, shorten hospital stay and accelerate postoperative rehabilitation.

Objective To observe the effect of intravenous anesthesia (IVA) with propofol (P),ketamine (K) and fentanyl (F) in different ways in children. Methods 90 pediatric patients were divided into three groups ( n =30) randomly according to the drug used for IVA. Ⅰgroup used compounds of P, F and K; Ⅱgroup used compounds of P and F; Ⅲ group used compounds of P and K. All the drugs were injected intravenously with micro-pump. Total dosage of anaesthetics, awaken time after operation and variation of circulation and breath were observed and sedative and analgesic effect during operation were evaluated. Results Compared with Ⅱ or Ⅲ group, Ⅰgroup showed less dosage, shorter awaken time and smaller degree of change in circulation and breath with complete sedation and analgesia ( P

Objective To determine the outcome of the combined use of flaps transfer and ilizarov technique reconstruct the large soft tissue defects and bone lose in the lower leg.Methods Sixteen patients were identified from a retrospective review from July,2008 to July,2013,who suffered the large soft tissue defects and bone lose in the lower leg and underwent single-stage soft tissue and osseous reconstruction using the flap technique and Ilizarov method.There were 12 males and 4 females aged from 22 to 62 years old (average 42.6 years old).The size of soft tissue defect ranged from 8 cm×9 cm to 30 cm×20 cm.The length of the bone discrepancy ranged from 2 to 14 cm.According to the local condition of the lower leg and the size of the composite tissue defects,10 patients received the free flap covering,6 patients repaired by the saphenous neurocutaneous perforator flap (3 cases) and sural nerve neurocutaneous flap (3 cases).Daily monitoring the skin temperature postoperative.Distraction was commenced on postoperative day 10 to 14 at the rate of 1 mm/day and continued in 4 equal increments.Results The follow-up time ranged from 18 to 36 months.Sixteen flaps survived completed,only 1 flap was observed the venous congestion in postoperative day 2.The duration of ilizarov application ranged from 3.5 to 18.0 months.All patients achieved final union.All patients were satisfied with the outcome of the surgery.Conclusion The combined use of neurocutaneous flap and Ilizarov technique for reconstruction of large composite soft tissue defect in the lower leg.Significantly reduce patient treatment time,improving traction osteogenesis of long bones and the ability of resistance to infection.

Objective To investigate the effects of eardiopulmonary bypass(CPB)on plasma nitric oxide (NO)and asymmetric dimethyl arginine(ADMA)concentrations in patients with congenital heart disease complicated with pulmonary hypertension undergoing open heart surgery.Methods Eighteen ASA Ⅱ or Ⅲ patients aged 11-40 yr weighing 26-59 kg undergoing open heart surgery under CPB were divided into 3 groups according to pulmonary arterial systolic pressure(PASP)(n=6 each):group Ⅰ PASP<30 mm Hg;group Ⅱ PASP 30-50 mm Hg and group Ⅲ PASP>50 mm Hg.Arterial blood samples were taken before induction of anesthesia (To,baseline),at the start and termination of CPB(T1,2)and 3,6,24 h after CPB(T3-5)for determination of plasma NO and ADMA concentrations.Results The three groups were comparable with respect to M/F sex ratio,age,body weight and CPB time.The plasma ADMA concentrations were significantly increased while NO concentrations were significantly decreased at termination of CPB(T2)and 3 and 6 h after CPB(T3,4)as compared with the baseline at T0 in group Ⅱ and Ⅲ.The plasma ADMA concentration were significantly higher and No concentrations were significantly lower at all time points in groupⅡand Ⅲthan in group Ⅰ.Conclusion CPB can increase plasma ADMA concentration and decrease plasma NO concentration in patients with congenital heart disease complicated with pulmonary hypertension undergoing open heart surgery.

Objective To evaluate the clinic role of diffusion tensor imaging in diagnosis of central nervous system diseases with damage of white matter fibro bands.Methods Ten healthy volunteers and sixty-four patients(31 cases of cerebral vascular disease, 7 cases of demyelinating disease, 7 cases of inflammatory disease, 10 cases of tumor, 2 cases of degenerative disease, 2 cases of congenital brain dysgenesis, 3 cases of brain atrophy, and 2 cases of others) underwent MRI examination, which included conventional T 1WI, T 2WI, T 2 Flair and diffusion tensor. Fractional anisotropy(FA) were measured in white matter tracts and gray matter.Results Ablation of white matter fibro tracts and reduction of FA could be found in 59 patients(92.1%).Erosion like alteration was seen in 12 patients(20.3%).In all the patients with tumors showed push and displacement of the white matter fibro tracts.Conclusion Diffusion tensor imaging can show lesions in white matter at early stage of some diseases.It is better in displaying damage or displacement of white matter tracts than conventional MRI.

Mechanical ventilation is regarded as an effective means of replacing artificial ventilation during cardiopulmonary resuscitation (CPR), and has been widely used in the treatment of cardiac arrest (CA) patients. However, there are still some controversial issues remaining to be settled, such as the assessmentof the effectiveness of mechanical ventilation, the selection of the optimal oxygen concentration (FiO2), tidal volume (VT), respiratory frequency, and mode of ventilation during the CPR process. The pros and cons of positive pressure ventilation are also inconclusive. We reviewed and summarized the related research in recent years, and recommended that the intermittent positive pressure ventilation (IPPV) of volume controlled with small VT (6-7 mL/kg), low ventilation rates (10 times/min), and pure oxygen could be applied during the mechanical ventilation of CPR. The best mechanical ventilation strategy still needs further experimental researches to discover and explore.
