Aim:To explore the feasibility and safely of greenlight photoselective vaporization of the prostate(PVP)on high-risk patients presenting with lower urinary tract symptoms suggestive of benign prostatic hyperplasia(BPH)and to evalu- ate their clinical and voiding ***:A total of 85 high-risk patients with obstructive BPH underwent PVP with an 80W potassium-titanyl-phosphate laser,which was delivered through a side-deflecting fiber with a 23 Fr continuous flow *** time,blood loss,indwelling catheterzation,international prostate symptom score(IPSS),quality of life score(QoL),uroflowmetry,postvoid residual urine volume and short-term complication rates were evaluated for all ***:All patients got through the perioperative period *** chief advantages of PVP were:short operative time(25.6±7.6min),little bleeding loss(56.8±14.3mL)and short indwelling catheterization(1.6±0.8d).The IPSS and QoL decreased from(29.6±5.4)and(5.4±0.6)to(9.5±2.6)and(1.3± 0.6),*** vast majority of patients were satisfied with voiding *** mean maximal urinary flow rate increased to 17.8 roLls and postvoid residual urine volume decreased to *** results are signifi- cantly different from preoperative data(Pfusion or fluid *** were few complications and very high patient satisfaction after ***:PVP has a short operative time and high tolerance,and is safe,effective and minimally invasive for high-risk patients,therefore it might be considered as a good alternative treatment for high-risk patients with obstructive urinary symptoms as a result of BPH.

We present the observational results from a detailed timing analysis of the black hole candidate EXO 1846-031 during its outburst in 2019 with the observations of Insight-HXMT,NICER and *** outburst can be classified roughly into four different ***-C quasi-periodic oscillations(QPOs)observed by NICER(about 0.1-6 Hz)and Insight-HXMT(about 0.7-8 Hz)are also reported in this ***,we study various physical quantities related to QPO *** QPO rms-frequency relationship in the energy band 1-10 keV indicates that there is a turning pointing in frequency around2 Hz,which is similar to that of GRS 1915+105.A possible hypothesis for the relationship above may be related to the inclination of the source,which may require a high inclination to explain *** relationships between QPO frequency and QPO rms,hardness,total fractional rms and count rate have also been found in other transient sources,which can indicate that the origin of type-C QPOs is non-thermal.

目的:探讨输尿管支架管(双"J"管)在肾结核治疗过程中,对于提高抗结核药治疗效果、保留患肾结构和功能的临床意义。方法:34例肾结核(22例合并单侧肾积水)患者随机分为2组,A组进行单纯抗结核药物治疗.B组在药物治疗前在患肾侧置入输尿管支架管(双"J"管)。抗结核药物治疗3个月后随访、复查。结果:治疗前两组尿常规、B超、静脉尿路造影(IVU)、CT和核素肾图检查结果无统计学差异,药物治疗3个月后随访显示两组间尿常规检查、红细胞沉降率异常、尿抗酸杆菌阳性率无统计学差异,而B超、CT检查、IVU和核素肾图结果差异具有统计学意义(P<0.05)。共21例患者行肾切除手术,A组15例(88.2%),B组6例(35.3%),具有统计学差异(P<0.05)。结论:肾结核药物治疗前在患肾侧置入输尿管支架管更有利于保留患肾的结构和功能,能降低患肾手术切除率。

目的建立一种新的输尿管战创伤动物模型，观察生物可降解输尿管支架在输尿管战创伤治疗中的降解特性。方法使用自行研制的火器弹片伤制造模具，对模型建立组9条比格犬的随机一侧输尿管制造火器弹片伤后清创缝合，分别于术后40、80、120d行静脉肾盂造影评估。再对阳性对照组9条比格犬的双侧输尿管均制造火器弹片伤，随机一侧放置聚乳酸可降解输尿管支架，另一侧放置双J管，分别于术后40、80、120d行静脉肾盂造影评估，支架行表面微观形貌及元素分析。结果模型建立组9条比格犬，损伤侧术后出现肾积水，并逐渐加重。阳性对照组的9条比格犬，术后双侧均未见明显肾积水；可降解支架随时间推移逐渐降解，尤其术后80d开始观察到降解速度明显加快；支架表面无钙沉积，而双J管表面可观察到明显钙沉积和结石形成，且随时间进展加重。结论生物可降解支架在治疗输尿管火器弹片伤过程中，在起到了支撑、引流、预防肾积水作用后，随时间推移逐渐降解，并可避免结石形成。
