Objective To explore the safety and effectiveness of transurethral resection of the prostate (TURP) for large benign prostatic hyperplasia.Methods A total of 56 cases of patients with large benign prostatic hyperplasia were analyzed retrospectively.Results The weight of prostate tissue resected with TURP was 60.2 g (48-122 g).The resection rate was 60％,operation time 113.4 min (70-180 min).The lower urinary tract symptoms (LUTS) after TURP was improved significantly.The international prostate symptom scores (IPSS) of 38 cases were decreased from (25.6±1.5) before operation to (6.0± 2.0) after operation.The maximum urine flow rate were increased from (5.0±1.9) ml/s to (18.0±4.5) ml/s.The mean residual urine volume of 22 cases were reduced from 95 ml (40-250 ml) to 10 ml (0-60 ml).Conclusions Skilled TURP technology for large benign prostatic hyperplasia is a safe treatment with good effect and low complications rates.

Objective To evaluate the blood-saving effect of combination of hemocoagulase artox for injection and tranexamic acid (TXA) in patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods Eighty ASA Ⅱ patients (NYHA Ⅰ or Ⅱ),aged 50-70 yr,weighing 50-100 kg,scheduled for elective OPCABG,were randomly divided into 4 groups (n =20 each):control group (group C),hemocoagulase atrox for injection group (group H,n =20),TXA group (group T) and hemocoagulase atrox for injection + ·TXA group (group HT).Hemocoagulase atrox 0.04 U/kg (the highest dose 4 U) was injected at 20 min before skin incision,and additional hemocoagulase atrox 2 U was given every 2 h starting from 15 min after administration of protamine until the end of operation in group H.TXA 20 mg/kg was injected intravenously at skin incision,followed by a continuous infusion of TXA at 10 mg· kg-1 · h-1 until the end of operation in group T.Hemocoagulase atrox and TXA were given as the method described in groups H and T.Venous blood samples were taken from the central vein before operation,at the end of operation,and 24 h after operation to determine the plasma D-Dimer concentration.The amount of blood loss,allogeneic red blood cells and plasma infused during operation,volume of drainage during 0-6 and 6-24 h after operation,total volume of drainage and volume of allogeneic blood transfused during operation were recorded.The deep vein thrombosis was recorded.Results Compared with group C,the amount of blood loss during operation was significantly decreased in groups T and HT,and the allogeneic red blood cells and plasma infused during operation,and volume of drainage during 0-6 and 6-24 h after operation,and total volume of drainage were significantly decreased in groups H,T and HT (P ＜ 0.05).Compared with groups H and T,the allogeneic red blood cells and plasma infused during operation,and volume of drainage during 0-6 and 6-24 h after operation,and total volume of drainage were significantly decreased in group HT (P ＜ 0.05).No deep vein thrombosis was observed in the 4 groups.Conclusion The combination of hemocoagulase artox for injection and TXA provides better blood-saving effect than either alone for the patients undergoing OPCABG without increasing the risk for thrombosis.

Object To investigate the features of health related quality of life ( HRQOL) among elderly hypertensive patients with different body mass index (BMI) so s to provide evidence for the health promotion of hypertensive. Methods A cross-sectional survey of health status data from a population of 1281 elderly hypertensive patients from Beijing and 8 provinces of China ( Jiangsu, Anhui, Gansu, Qinghai, Fujian, Jilin, Jiangxi, and Henan) was made in the study. Analysis of variance was applied to compare the differences in HRQOL of elderly hypertensive patients in different BMI categories. Results For the elderly hypertensive patients with low body mass index, the scores of 8 dimensions and scores in physical component summary (PCS) and mental component summary( MCS) of SF-36 were the lowest;except the role-emotional(RE) dimension,the scores of other 7 dimensions,PCS and MCS were significantly different(PF,RP,BP,GH,VT,MH, P<0.01; SF,PCS,MCS, P<0.01). Comparing the scores between any two groups in PCS, the scores of patients with low body mass index were significantly lower than normal weight group (62.30 ± 22. 12 vs72.40 ±20.86, P<0.05) .overweight group (62.30 ± 22.12 vs 74.97 ± 19.20, P<0.05 ) and obese group (62.30 ± 22.12 vs 74.57 ± 19. 22, P < 0.05 ). Comparing the scores between any two groups in MCS,the scores of patients with low body mass index were significantly lower than normal weight group (68. 81 ± 20. 48 vs 74. 70 ± 20.41, P < 0. 05), overweight group (68. 81 ± 20. 48 vs 78.08 ±18.23, P<0.05) and obese group (68.81 ±20.48 vs 78. 69 ± 17.77, P<0.05); the score of normal weight group was significantly lower than the overweight group (74. 70 ±20. 41vs 78. 08 ±18.23, P<0.05). Gender Stratification showed that females with low body mass index had worse HRQOL than males. Conclusion The HRQOL of elderly hypertensive patients with low body mass index is significantly lower than normal weight patients, overweight patients and obese patients, the health promotion of elderly hypertensive patients with low body mass index should be paid more attentions, especially females with low body mass index.

Objective To create a new animal model which can preferably simulate the human's scoliosis. Methods Forty-five 4-week-old female Wistar rats were randomly divided into 3 groups. Group 1 underwent subcutaneous left scapula-to-contralateral ilium tethering procedure with a non-absorbable suture,which made the spine convex towards right side, and then removed forelimbs and tails of rats to create the bipedal rats. Tethering sutures were cut at postoperative 8th week, and the spines of rats were then observed during 2 weeks. Group 2 were the same as group 1 but in which scapula-to-ipsilateral ilium tethering procedure was performed. Group 3 were the same as group 1 except that the bipedal rats were not created. All postoperative rats were fed separately in special high cages for group 1 and group 2 or in standard cages for group 3. Operative duration, postoperative first food-taking duration, operative mortality, body weight, relative length of the spinal cord, Cobb angles in the coronal and sagittal planes, modeling mortality, the incidences of re-operation, scoliosis and vertebral rotation among the 3 groups were compared. Results There were no significant differences in the degree of scoliosis or kyphosis among the 3 groups at the time of initial tethering. At 2 weeks after tether release, the incidence of vertebral rotation was significantly higher in group 1 than group 2 (86.7% vs. 33.3%), and the degree of scoliosis or kyphosis was significantly larger in group 1 than group 3 (coronal plane: 30.2°±10.4° vs. 20.5°±7.7°; sagittal plane: 55.6°±10.0° vs. 43.8°±6.3°). There was no significant difference in postoperative first food-taking duration among the 3 groups, and no death of rats occurred in all groups during intraoperative and postoperative 6 hours, although operative duration was significantly longer in group 1 or group 2 than group 3. There were no significant differences in body weight,relative length of the spinal cord, modeling mortality, the incidences of re-operation and scoliosis among the 3 groups. Conclusion The bevel and axial loads of the vertebrae can significantly enhance the incidence of vertebral rotation and the degree of kyphoscoliosis, respectively. The scoliosis model created by scapula-to-contralateral ilium tethering procedure in bipedal rats can preferably simulate the human's scoliosis.
