Objective To study the spectrum structure of X-ray and simplify the description method of it. Methods By the general program of Monte Carlo Geant4 to study X-ray spectrum structure and angular distribution of X-ray energy spectrum. Results The results of percentage depth doses and profile curves at different depths of any radiation fields in water phantom calculated by Monte Carlo Geant4 were consistent with the measurements. Conclusions In radiotherapy, X-ray with same nominal energy have very similar dosimetry characteristics, this indicates they have very similar energy spectrum and angular distribution of spectrum. the differences of dosimetric details reflect the different details of the X-ray spectrum structure and angular distribution of X-ray energy spectrum. These studies have very important significances to rapidly build precise virtual source modeling for Monte Carlo calculation based on dose curves measurements in water phantom.

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.

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 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.
