Doxorubicin is a hydrophilic anticancer drug. Due to hydrophilicity, it’s difficult to encapsulate in a hydrophobic core of nanomicelles. The main purpose of this study was to develop a hydrophobic ion paring complex (HIP) of doxorubicin using hydrophobic retinoic acid (Vitamin A). The resultant hydrophobic (DOX-RA) complex was utilized to prepare drug-loaded nanomicelles by co-precipitation method with penta block copolymer. Nanomicelles (DOX-RA/PBNM), was prepared by evaporation rehydration technique. DOX-RA complex was analyzed by H-NMR and FTIR. The nanomicelles were analyzed for size and zeta potential using dynamic light scattering (DLS) as well as transmission electron microscopy (TEM). The FT-IR and the H-NMR analyses confirmed the structures of the DOX-RA complex. Mean nanomicellar sizes were 25.5nm ± 5.00nm, and ζ-potential was approximately zero. H-NMR and FTIR analysis done on DOX-RA indicate peaks characteristic of both doxorubicin and retinoic Acid. This confirmed successful complex formation. Transmission electron microscopy (TEM) analysis revealed round shaped morphology and sizes similar to DLS results. In vitro release studies revealed that pentablock nanomicelles released Doxorubicin at a slow first order rate in phosphate buffer solution (PBS) at pH 7.4 compared to pH 5.5 and pH 4.0. Confocal microscopy analysis with DOX-RA/ PBNM indicated that pentablock nanomicelles were efficiently taken into prostate cancer (PC3) cells and doxorubicin was efficiently released from the nanomicelles into the cells. In addition, cell proliferation assay showed that nanomicelles ferried adequate amounts of Doxorubicin into PC-3 cells and inhibited cell growth significantly. Results confirm that DOX-RA complex facilitated the encapsulation of doxorubicin within nanomicelles increasing DOX intracellular concentration. Volume 1 Issue 4 Copyrights @ Alex Oselu Owiti.

It is important to develop new delivery systems that capable of ferrying sufficient amount of drug to the tumor cells, thereby avoiding the multidrug resistance and frequent dose administrations of chemotherapeutics. One of the attempts to elevate the drug bioavailability in tumor tissue is the application of site-specific delivery systems that may release the encapsulated drugs within tumor cells.

阿霉素是一种亲水性抗癌药。由于亲水性,它很难被包裹在纳米胶束的疏水核心中。本研究的主要目的是利用疏水维甲酸(维生素a)制备阿霉素疏水离子配对配合物(HIP),并利用该疏水离子配对配合物与五嵌段共聚物共沉淀法制备载药纳米胶束。采用蒸发复水合法制备了DOX-RA/PBNM纳米胶束。用H-NMR和FTIR对DOX-RA配合物进行了分析。利用动态光散射(DLS)和透射电子显微镜(TEM)分析了纳米胶束的大小和zeta电位。FT-IR和H-NMR分析证实了DOX-RA配合物的结构。平均纳米束尺寸为25.5nm±5.00nm, ζ电位近似为零。对DOX-RA进行的H-NMR和FTIR分析显示了阿霉素和维甲酸的峰特征。这证实了复杂地层的成功。透射电镜(TEM)分析显示圆形形态和大小与DLS结果相似。体外释放研究表明,与pH 5.5和pH 4.0相比,五块纳米胶束在pH 7.4的磷酸盐缓冲溶液(PBS)中以缓慢的一级速率释放阿霉素。DOX-RA/ PBNM共聚焦显微镜分析表明,五块纳米胶束被有效地进入前列腺癌(PC3)细胞,阿霉素被有效地从纳米胶束释放到细胞中。此外,细胞增殖实验表明,纳米胶束将足够量的阿霉素输送到PC-3细胞中,并显著抑制细胞生长。结果证实,DOX- ra复合物促进了阿霉素在纳米胶束内的包封,增加了细胞内DOX浓度。版权所有@ Alex Oselu Owiti。J Urol Neph St引用:Alex Oselu Owiti。多柔比星-维甲酸髋部复合纳米胶束制剂的制备及其在前列腺癌中的应用。[J]武汉大学学报(自然科学版)1(4)2019。JUNS.MS.ID.000118。DOI: 10.32474 / JUNS.2019.01.000118。80此外,非靶向递送可能对健康细胞造成严重的细胞毒性作用。这些可能导致剂量依赖性心脏损伤、多药耐药和骨髓抑制,从而限制了其治疗应用[5]。开发能够向肿瘤细胞运送足量药物的新输送系统,从而避免化疗药物的多药耐药和频繁给药是很重要的。提高药物在肿瘤组织中的生物利用度的尝试之一是应用位点特异性给药系统,使包膜药物在肿瘤细胞内释放。另一种方法是通过特异性靶向肿瘤细胞来获得更高的药物积累。然而,如果不使用细胞表面上的目标所特有的配体,这可能很难实现。由于缺乏合适的配体,最终可能会将药物输送到不需要的部位[6]。已知肿瘤微环境的一些内在变化,如酶、pH和氧化应激,以及外在因素,如光、温度和磁场,会导致肿瘤细胞和组织内特定部位的药物释放[7]。pH触发药物从纳米载体释放是最容易被接受的直接在细胞质内释放药物的方式[7]。这种利用肿瘤酸性微环境触发药物释放的策略存在不足,因为肿瘤的最低pH值位于远离肿瘤血管的位置[8]。由于肿瘤间质区pH值低于6.5,纳米载体的能力可能受到限制。例如,一些载体(如脂质体)在到达预定目标之前变得不稳定并发生改变。另一种有前途的用于递送疏水药物的纳米制剂是纳米胶束。与脂质体等其他载体相比,纳米胶束表现出更高的效率。它们还具有生物利用度高、被包被药物稳定性提高、包被和载药效率高、缓释效果好等优点[9]。此外,其生产中使用的大多数材料对所有形式的给药都是生物安全的。这些纳米胶束的应用是在改善药物进入肿瘤组织的能力方面,同时通过限制非选择性细胞毒性来减少剂量和提高药物疗效[10-13]。为了引起ph触发的多柔比星(DOX)的细胞内释放,利用亲脂分子维甲酸(RA)形成离子配对复合物(DOX-RA)。形成的离子对在pH < 7.0的酸性微环境中表现出不稳定性,与肿瘤组织相容。该复合物在pH值为7.4的环境(例如血液)中保持稳定[14]。

Angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARBs) are recommended in peritoneal dialysis (PD) patients for hypertension or heart failure control [1] Angiotensin II (AII) is an important factor in the development of renal fibrosis due to its hemodynamic effects on glomeruli and stimulation of extracellular matrix proteins synthesis, mediated by TGF b [2]. This may explain why treatment with ACEi and ARBs is renoprotective in patients with diabetic and non-diabetic nephropathy.
血管紧张素转换酶抑制剂(angiotensin -converting enzyme inhibitors, ACEi)和血管紧张素受体阻滞剂(angiotensin II receptor blockers, ARBs)被推荐用于腹膜透析(PD)患者的高血压或心力衰竭控制[1]。血管紧张素II (angiotensin II, AII)通过TGF b介导对肾小球的血流动力学作用和刺激细胞外基质蛋白合成,是肾纤维化发生的重要因素[2]。这也许可以解释为什么ACEi和ARBs治疗对糖尿病和非糖尿病肾病患者具有肾保护作用。

Background: Tumor lysis syndrome (TLS) is an oncologic emergency that can occur spontaneously or triggered by cancer treatment. This life-threatening condition is most commonly seen in hematologic cancers but is sometimes described in solid tumors such as germ cell tumors (GCTs). The objective of this study is to investigate the clinical characteristics and outcomes of TLS in GCTs. Methods: Retrospective review and pooled analysis. Result: Seventeen cases of TLS related to GCTs were identified. These included nonseminomatous GCT (7), seminoma (5), choriocarcinoma (2), ovarian (2), and intracranial germinoma (1). Nine cases (53%) of TLS were treatment-related and eight cases (47%) occurred spontaneously. The median age of patients was 34 years (range: 13-58), excluding one newborn baby. The median time from treatment to TLS was 2.1 days. Seven patients (41%) had liver metastases, but all patients had bulky disease. All of the patients received supportive measures; 4 (24%) patients received rasburicase and 11 patients (64%) underwent hemodialysis. The mortality rate was 44.4% among the nine cases of treatment-related TLS. The mortality rate was 37.5% in the eight patients with spontaneous TLS (STLS). Conclusion: TLS can occur in GCTs that have a high tumor burden. Almost 50% of TLS in GCTs happened spontaneously. Considering the life-threatening nature of TLS in GCTs, health professionals should be alert and monitor for TLS in order to prevent or treat this potentially fatal complication.
背景:肿瘤溶解综合征(TLS)是一种肿瘤急症,可自发发生或由癌症治疗引发。这种危及生命的疾病最常见于血液肿瘤,但有时也见于生殖细胞瘤(gct)等实体肿瘤。本研究的目的是探讨gct中TLS的临床特征和预后。方法:回顾性分析和汇总分析。结果:共鉴定出17例与gct相关的TLS。其中包括非精原细胞瘤性GCT(7例)、精原细胞瘤(5例)、绒毛膜癌(2例)、卵巢(2例)和颅内生殖细胞瘤(1例)。tls9例(53%)与治疗相关,8例(47%)自发发生。患者的中位年龄为34岁(范围:13-58岁),不包括1名新生儿。从治疗到TLS的中位时间为2.1天。7例(41%)患者有肝转移,但所有患者都有大块病变。所有患者均接受支持性措施;4例(24%)患者接受了rasburicase治疗,11例(64%)患者接受了血液透析。9例治疗相关TLS患者死亡率为44.4%。8例自发性TLS (STLS)患者死亡率为37.5%。结论:肿瘤负荷高的gct可发生TLS。gct中几乎50%的TLS是自发发生的。考虑到gct中TLS危及生命的性质,卫生专业人员应该警惕和监测TLS,以预防或治疗这种潜在的致命并发症。

Comparison of Endoscopic Injection of Vantris and Gil-Vernet surgery in the Treatment of Primary Vesicoureteral Reflux (VUR) 内镜下注射Vantris与Gil-Vernet手术治疗原发性膀胱输尿管反流(VUR)的比较
Pub Date : 2019-01-01 DOI: 10.13188/2380-0585.1000027
Purpose: Vesicoureteral Reflux (VUR) is the most common urologic condition in pediatric population, affecting almost 1% of children. The present study aims to compare outcomes of an open surgical technique (Gil-Vernet), an old-fashioned method still performed in some centers, and the endoscopic correction using Vantris as a preferred less invasive method in children with VUR. Materials and methods: In this randomized clinical trial, a total of 61 children with VUR of grades I-IV underwent either open surgical repair using the Gil-Vernet approach (30 patients, 50 renal refluxing units), or endoscopic repair using Vantris as the bulking agent (31 patients, 49 renal refluxing units). The change in VUR grade before and after operation was compared between the two groups. Results: The Vantris group comprised 5 males and 26 females with the mean age of 6.15±2.26 years (range, 1-10) versus the Gil-Vernet that included 9 males and 21 females with the mean age of 5.23±2.05 years (range, 1-10) (p=0.20 and 0.21, respectively). The VUR grade decreased significantly in both groups after operation (p<0.001), but despite a better improvement in the Vantris patients the inter-group analysis missed a statistically significant level in a marginal fashion (p=0.07). The rate of improvement and full improvement was 98% and 81.6% in the Vantris group vs. 94% and 86% in the Gil-Vernet group, respectively (p=0.62 and 0.56, respectively). Conclusion: Although postoperative improvement in VUR grade was better in the Vantris® group than that in the Gil-Vernet group, the difference was not statistically significant. Both methods of treatment were safe and with a high rate of success. Nevertheless, lesser manipulations performed in Vantris® makes it favorable comparing with open Gil-Vernet method.

After explaining the study terms and conditions, the children were categorized into one of the groups of Vantris endoscopic injection (Promedone, Cordoba, Argentina) or Gil-Vernet open surgery.

目的:膀胱输尿管反流(VUR)是儿科人群中最常见的泌尿系统疾病,影响近1%的儿童。本研究旨在比较开放式手术技术(Gil-Vernet)的结果,这是一种仍在一些中心使用的老式方法,以及使用Vantris作为一种首选的微创方法对儿童VUR进行内镜矫正的结果。材料和方法:在这项随机临床试验中,共有61名I-IV级VUR儿童接受了Gil-Vernet入路的开放手术修复(30例患者,50个肾反流单位),或使用Vantris作为膨胀剂的内镜修复(31例患者,49个肾反流单位)。比较两组患者手术前后VUR分级的变化。结果:Vantris组男性5例,女性26例,平均年龄6.15±2.26岁(范围,1 ~ 10);Gil-Vernet组男性9例,女性21例,平均年龄5.23±2.05岁(范围,1 ~ 10)(p分别为0.20和0.21)。两组患者术后VUR评分均显著下降(p<0.001),但尽管Vantris组患者改善较好,但组间分析在边际方式上没有统计学显著水平(p=0.07)。Vantris组的改善率为98%,完全改善率为81.6%,Gil-Vernet组为94%,完全改善率为86%,差异有统计学意义(p=0.62, 0.56)。结论:虽然Vantris组术后VUR分级改善优于Gil-Vernet组,但差异无统计学意义。这两种治疗方法都是安全且成功率高的。然而,与开放式Gil-Vernet方法相比,在Vantris®中进行的较少操作使其具有优势。引用本文:Rashed FK, Roshandel MR, Aghaei Badr T, Motlagh RS。内镜下注射Vantris与Gil-Vernet手术治疗原发性膀胱输尿管反流(VUR)的比较。中华泌尿外科杂志,2019;6(1):5。中国泌尿外科杂志6(1):5 (2019)Page 02 ISSN: 2380-0585畸形,包括梗阻或完全重复的膀胱系统,通过临床表现怀疑或证实排尿功能障碍,包括异常神经学检查或肠功能障碍或梗阻性刺激LUTS,通过VCUG或超声证据证实膀胱壁不规则或憩室或小梁,膀胱体积小和神经源性膀胱。61例膀胱输尿管反流患者(100肾单位)经VCUG证实其反流和疾病分级后,根据预先确定的纳入和排除标准纳入。在解释研究条款和条件后,将儿童分为Vantris内窥镜注射组(Promedone, Cordoba,阿根廷)和Gil-Vernet开放手术组。所有手术均由一名儿科泌尿科医生完成,该医生接受过10年以上的内窥镜注射经验培训。在接受内镜注射的患者中(31例,50肾单位),在输尿管口6点钟位置,通过紧凑膀胱镜使用6- french尺寸和23号针头在输尿管内粘膜下注射Vantris填充材料(STING法)。对于反流程度较高且输尿管口非常疏松的患者,将其注入输尿管内。注射量从0.2到约2cc不等,取决于患者。患者于手术当天出院,口服抗生素治疗一周。最后,由于手术后退出试验,无法对一个肾单位进行随访,该组共调查了49个肾单位。在Gil-Vernet抗反流手术组(30例患者,50个肾单位),患者接受经典Gil-Vernet抗反流手术。在这种技术中,在单侧反流的情况下,双方都进行手术以防止由于三角区不稳定而导致对侧反流。这些患者在两天后出院。患者术后未置Foley导尿管,术后一周抗生素治疗出院。所有患者术后两周均行肾积水超声检查(作为并发症)。术后3个月行膀胱输尿管造影(VCUG)随访反流。VCUG图像的记者不知道治疗的类型。治疗成功的定义是消除或减轻反流的严重程度。统计分析数据以均数±标准差,或标准误差(如有必要)和频率(%)报告。统计软件SPSSTM Variable Vantris(31例)开放手术(30例)P值*

Urethral ectropion is most common in young girls than elderly woman. The objective in this study was to show anatomopathologic and clinic types of urethral ectropion. We were reported two cases in young girls and one case in 67 years old woman. The clinical symptoms were same. But in the case of old woman we founded right lymph nodes. Biopsy had done in two cases on three. In one of both girls we were discovered after anatomopathology, a vessels thrombosis but in a year-old-woman it was urethral adenocarcinoma. Management of urethral ectropion depends of age (young girl or elderly woman) and staging of tumor if it was urethral carcinoma. with which she was then treated. A biopsy of the urethral prolapse was made for anatomopathological analysis. The result was a urethral adenocarcinoma. Uroscanner objectified the presence of bilateral
尿道外翻在年轻女孩中比在老年妇女中更常见。目的在本研究是显示解剖病理和临床类型的尿道外翻。我们报告了2例年轻女孩和1例67岁妇女。临床症状相同。但在老妇人的病例中我们发现了右侧淋巴结。三个病例中有两个做了活检。在解剖病理后,我们发现两个女孩中的一个是血管血栓形成,但在一个一岁的女人是尿道腺癌。尿道外翻的处理取决于年龄(年轻女孩或老年妇女)和肿瘤的分期,如果是尿道癌。然后她就被这样对待了。对尿道脱垂行活检进行解剖病理分析。结果是尿道腺癌。尿路扫描仪将双侧存在客观化

Pub Date : 2018-09-07 DOI: 10.32474/JUNS.2018.01.000112

Objectives: Benign prostatic hyperplasia (BPH) is an internationally important health problem of the man, particularly in developed countries. The aim of this exploratory study was to evaluate whether significant changes in the levels of Zn and some other trace elements of prostatic fluid exist in the hyperplastic prostate. Methods: Prostatic fluid levels of Br, Fe, Rb, Sr, and Zn were prospectively evaluated in 52 patients with BPH and 38 healthy male inhabitants. Measurements were performed using 109Cd radionuclide-induced energy dispersive X-ray fluorescent microanalysis. Prostatic fluid samples were divided into two portions. One was used for morphological study while the other was intended for trace element analysis. Results: Mean values ± standard error of means (M±SΕΜ) for concentration (mg/L) of trace element in the expressed prostatic fluid (EPF) of normal prostate were: Br ±2.86±0.59, Fe 8.30±1.42, Rb 1.16±0.10, Sr 1.27±0.17, and Zn 598±34. It was observed that in the EPF of hyperplastic prostate content of Rb significantly increased whereas content of Zn somewhat decreased in a comparison with those in the EPF of normal prostate. Conclusions: There are significant changes in trace element contents and their relationships in the fluid of hyperplastic prostate. The alterations in levels of Zn and Rb in the EPF of hyperplastic prostate might demonstrate an involvement of these trace elements in etiology and pathogenesis of BPH. It was supposed that the changes of Zn and Rb levels in the EPF samples can be used as BPH markers.
目的:良性前列腺增生(BPH)是国际上重要的男性健康问题,特别是在发达国家。本探索性研究的目的是评估前列腺增生是否存在前列腺液中锌和其他微量元素水平的显著变化。方法:对52例前列腺增生患者和38例健康男性进行前列腺液中Br、Fe、Rb、Sr和Zn水平的前瞻性检测。测量采用109Cd放射性核素诱导能量色散x射线荧光微量分析。前列腺液样本分为两部分。一个用于形态学研究,另一个用于微量元素分析。结果:正常前列腺表达前列腺液(EPF)中微量元素浓度(mg/L)的均值±标准误差(M±SΕΜ)为:Br±2.86±0.59,Fe 8.30±1.42,Rb 1.16±0.10,Sr 1.27±0.17,Zn 598±34。结果表明,与正常前列腺EPF相比,增生性前列腺EPF中Rb含量明显升高,而Zn含量有所降低。结论:前列腺增生液中微量元素含量有显著变化及其关系。前列腺增生EPF中Zn和Rb水平的变化可能表明这些微量元素参与了前列腺增生的病因和发病机制。推测EPF样品中Zn和Rb水平的变化可作为BPH的标志物。

Renal rehabilitation based on early body movement in intensive care units that has been expanding its fields of action from the areas of health promotion, disease prevention, maintenance and rehabilitation of people from the center of study human body movement applied in comprehensive care in intensive care units, which leads to reflection on a reflective theoretical discernment process of conceptual elements that lead to understand the ethical vision of the concept of body and movement in a hospitalization context from the renal environment where key aspects such as pain, care, dysfunctions, limitations and disabilities resulting from the immobilization process are articulated in the bioethical principles from the praxis of human movement.
肾脏康复以重症监护室早期身体运动为基础,其行动领域已从健康促进、疾病预防、维持和康复等领域不断扩大,从人体运动研究中心应用于重症监护室的综合护理。这导致了对概念要素的反思性理论识别过程的反思,从而从肾脏环境中理解住院环境中身体和运动概念的伦理视野,其中诸如疼痛,护理,功能障碍,由固定过程引起的限制和残疾等关键方面在人类运动实践的生物伦理原则中得到阐述。

Development of novel methods for controlled coarse fragmentation of urinary tract stones may help to minimise the risk of urinary tract infection and prevent the small stone fragments, responsible for residual stone formation, from entering into the calyxcalcification system of a kidney. The experimental results demonstrated that the following parameters of a pulsed laser operating at the 2097 nm (or the 1967 nm) wavelength were optimal for a controlled fractioning of the stones in air: the pulse duration of 20-30 ns, the repetition rate of 200-1000 Hz (or more), and pulse energy of 45-55 mJ. The relatively small pulse energy coupled with the high repetition rate enabled the destruction of concrements into fragments small enough to be removed with the amplatz.
