Objective To compare the safety and efficiency of endoscopic total extraperitoneal patchplasty(TEP)and modified Kugel hernioplasty for inguinal hernia.Methods The clinical data of 284 cases(312 surgeries)of preperitoneal inguinal hernia repair,including 134 cases(152 surgeries)of TEP and 150 cases (160 surgeries)of modified Kugel hernioplasty,were retrospectively evaluated from June 2009 to June 2011.Mean operative time,postoperative hospital stay,postoperative complications and recur-rence were compared between groups.Results There were no significant differences in mean operative time [(48.75 ±12.14)min vs(51.46 ±24.76)min,P=0.248],postoperative hospital stay [(5.23 ± 1.85)d vs(5.84 ±1.52),P=0.126],postoperative complications [5 cases(3.3%)vs 8 cases(5.0%), P=0.598]and recurrence [1 case(0.7%)vs 2 cases(1.3%),P=1.00]between TEP and modified Kugel hernioplasty,espectively.Conclusion TEP and modified Kugel hernioplasty are both methods for preperitoneal hernia repair and they can completely repair the defect of myopectineal orifice.They are safe and effective,which is worthy of being spread in clinical practice.

[Objective]To discuss the operative treatments and evaluate the effects of reconstruction interlocking nail(RIN)in treating femoral shaft fractures associated with ipsilateral peritrochanteric fractures of the femur.[Method]A retrospective study was done on 37 patients with femoral shaft fractures combined with ipsilateral peritrochanteric fractures treated by RIN from September 2002 to Janurary 2009.This study involved 32 males and 5 females,with an average age of 36 years (range,24 to 69 years).Thirty-three patients had high-energy injury (26 of road accident,7 of falling from height),and 4 low-energy injury.Among them,13 patients had fractures in the upper one-third of the femoral shaft,18 in the middle one-third and 6 in the lower one-third.Six patients had open fractures (Gustilo scale Ⅰ in 1,and Ⅱ in 5).According to Garden classification for femoral neck fractures,there were 19 cases of type Ⅱ,9 cases of type Ⅲ and 2 cases of typ Ⅳ.According to AO classification for femoral intertrochanteric fractures,there were 3 cases of type A1.1,1 case of type A2.1.According to Seinsheimer classification for femoral subtrochanteric fractures,there was 1 case of type Ⅰ,and 2 cases of type ⅡA.The mean duration from injury to surgery was 3.7 days (range,4 hours to 13 days).After operation step-by-step functional rehabilitation was encouraged.[Result]The follow-up periods ranged from 14 to 38 months (average,24 months).Bony union was achieved in all patients.The average bony union time was 13 weeks for fractures of femoral shaft,14 weeks for femoral neck,12.6 weeks for intertrochanteric and 15.5 weeks for subtrochanteric fractures.Femoral head necrosis occurred in one case.No such complications as infection,loosening of nails,coxa vara,or malunion was found.According to Harris Scoring system,32 cases (86.5%)were rated as good or excellent.[Conclusion]The treatment of femoral shaft fractures associated with ipsilateral peritrochanteric fractures of the femur with RIN is a good method because of its advantages of small trauma,stable fixation,high union rate,few complications and good results.It may have fewer internal fixators.Carefully choosing suitable patients,sophisticated operation skills and active functional exercise after operation are keys to success.

Objective To explore the detection significance of brain natriuretic peptide in peripheral blood of patients with coronary heart disease(CHD).Methods 260 patients with CHD were selected and divided into 95 cases of stable angina pectoris(SAP) group,85 cases of unstable angina pectoris(UAP) group and 80 cases of acute myocardial infarction(AMI) group according to angiographic and clinical diagnosis.Another 80 cases of healthy people which were taken medical examination were selected as the healthy control group.The peripheral blood plasma brain natriuretic peptide concentration of the study objects were detected,and the severity of coronary lesions was quantified by the coronary Gensini score.Results The peripheral blood brain natriuretic peptide average concentration of UAP group and AMI group was (498.00 ± 87.00) ng/L and (936.00 ± 102.25) ng/L,respectively,which were significantly higher than that of the SAP group [(213.46 ± 98.35) ng/L] and the control group [(97.63 ±20.07) ng/L] (t =8.78,12.01,6.26,2.38,all P ＜ 0.05).The peripheral blood brain natriuretic peptide concentration of patients with Gensini score≥20 points was significantly higher than that of the patients with Gensini score ＜20points(P ＜ 0.05).Conclusion The peripheral blood brain natriuretic peptide concentration of patients with CHD is correlated with coronary plaque stabilization and lesion severity.

ObjectiveTo analyze the effects of high-order scattered X-ray in dose calculation in radiotherapy,to resolve the problem of correcting the dose contribution of secondary and high-order scattering X-ray to the primary scattered X ray,and to provide a support for photon fast dose calculation method of Monte Carlo.MethodsBy the theory of cross-section in interaction between X-ray with material and Monte Carlo calculating results,to analysis the relative importance of primary scattered X-ray,secondary and high-order scattered of X-ray in dose calculation.ResultsThe contribution of secondary and high-order scattered X-ray to dose calculation was very small,it can be corrected to the primary scattered X-ray with a correction factor.ConclusionsThe results show that we can obtain a precise dose calculation for radiotherapy by only to tracking the contribution of primary X-rays and primary scattering X-ray,so,to establishing the database for primary scattering X-ray by Monte Carlo methods is important for fast dose calculation of Monte Carlo method.

Objective To compare the clinical efficacy and safety between transurethral plasma kinetic enucleation of prostate(TUPKEP) and transurethral resection of prostate(TURP) on benign prostatic hyperplasia(BPH). Methods One hundred and forty two BPH patients were divided into two groups:TUPKEP group (72 cases) and TURP group (70 cases). Seventy two cases aged 52-90 years[mean age (70. 5±7.6) years] with prostate weight of 27-126 g [mean weight (75. 6±10. 3)g] underwent TUPKEP, and seventy cases aged 51-87 years[mean age (70. 2±6. 8) years] with prostate weight of 25-118 g[mean weight (73.8±9.9)g] underwent TURP. There were no significant differences in age, weight of the prostate, international prostate symptom score(IPSS), residual urine volume(RUV) ,maximum urinary flow rate (Qmax) and quality of life (QOL) scores between the two groups before operation (t=0. 2873, 1.0612, 1. 0832,0. 9522,0. 0000, 1. 0774;P=0. 7743,0. 2904, 0. 2806,0. 3426,1. 0000,0. 2832). The operative time, intraoperative blood loss, the preserved time of installing catheter, hospitalization time, postoperative morbidity rate and efficacy were compared between the two groups. Results The operation success rates were 100. 0% (72/72) in TUPKEP group and 98.6% (69/70) in TURP group. The average operation time were (46.2±6.4)min and (58. 4±9. 6)min (t±8. 9404, P=0.0000), and the mean intraoperative blood loss were (105.9± 12.2)ml and (148.6±14.3) ml(t=19. 1608, P=0.0000) in TUPKEP and TURP groups respectively. The mean preserved time of installing catheter were (3. 5±1.0)d and (5.0±1.0)d(t= 8. 9364, P=0. 0000), and the average hospitalization time were (5.1±1.9) d and (7.0±2.6) d (t= 4. 9819,P=0.0000)in the two groups, respectively. In TUPKEP group, there was one case of temporary urinary incontinence, two cases of secondary prostate hemorrhage and one case of external orifice stricture of urethra, with a complication rate of 5.56%. In TURP group, there were two cases of transurethral resection syndrome (TURS), one case of urinary extravasation, two cases of temporary urinary incontinence, three cases of secondary prostate hemorrhage and two cases of external orifice stricture of urethra, with a complication rate of 14.29% . Compared with preoperation, Qmax was obviously increased and IPSS,RUV, QOL scores were decreased after follow- up for 3 months, but there were no significant differences in these parameters between the two conditions(t=1. 1131,0. 2543,1. 2959,0. 7252;P=0. 2676,0. 7996,0. 1971,0. 4696). Canclusions TUPKEP and TURP have similar efficacy in the treatment of BPH, but TUPKEP is a method with shorter operation time, less blood loss, lower postoperative complication rate and more safety than TURP.
