Deregulated microRNA-22-3p in patients with sepsis-induced acute kidney injury serves as a new biomarker to predict disease occurrence and 28-day survival outcomes

Background

Acute kidney injury (AKI) is a common and serious complication of sepsis. MicroRNA-22-3p (miR-22-3p) has been found to be involved in septic AKI progression. The purpose of this study was to analyze both the serum and urinary expression of miR-22-3p in septic AKI patients, and evaluated the clinical value of miR-22-3p in the diagnosis and prognosis of sepsis-induced AKI.

Methods

Serum and urinary expression of miR-22-3p was examined using qRT-PCR. The risk factors related with septic AKI onset were assessed using logistic analysis. A receiver-operating characteristic (ROC) curve was constructed to evaluate the diagnostic performance of miR-22-3p, and the Kaplan–Meier survival curves and Cox regression analysis were used to evaluate the predictive value of miR-22-3p for the 28-day survival of septic AKI patients.

Results

Both serum and urinary miR-22-3p expression was decreased and negatively correlated with kidney injury biomarkers in septic AKI patients. MiR-22-3p expression was a risk factor for AKI onset and had diagnostic accuracy in septic AKI patients. The expression of both serum and urinary miR-22-3p was lower in patients who died, and served as a prognostic biomarker to predict 28-day survival in septic AKI patients.

Conclusion

Serum and urinary miR-22-3p was reduced in sepsis-induced AKI patients, and served as a biomarker to predict AKI occurrence and 28-day survival in sepsis patients.

     

Comparison of efficacy and safety of daily oral L-arginine and PDE5Is alone or combination in treating erectile dysfunction: A systematic review and meta-analysis of randomised controlled trials

The meta-analysis was performed to assess the efficacy and safety of daily oral L-arginine and phosphodiesterase type 5 inhibitors (PDE5Is) alone or combination in treating patients with erectile dysfunction (ED). We performed a search of randomised controlled trials in the following databases: PubMed, EMBASE and Cochrane Library databases. Four articles including 373 patients were studied. Erectile functions were significantly improved in three therapy groups compared with baseline. Patients who received the combination of L-arginine and PDE5Is showed significant improvement compared to those treated with L-arginine and PDE5Is alone, as assessed by sexual function index (p <0.00001 and p =0.005, respectively) and total testosterone (p <0.00001 and p =0.0007, respectively). Furthermore, patients who treated with PDE5Is alone exhibited the better efficacy than those treated with L-arginine alone in respects of sexual function index (p <0.00001) and total testosterone (p =0.0001). However, the combination of L-arginine and PDE5Is had no obvious difference relative to PDE5Is alone in terms of various adverse events (AEs). Conclusively, compared with monotherapy, the combination of L-arginine and PDE5Is showed a greater improvement of sexual function and total testosterone, and did not significantly increase the AEs. Besides, PDE5Is alone revealed a better effect than those treated with L-arginine alone for patients with ED.     

Analysis of pharmacological mechanisms of Yinyanghuo as treatment of erectile dysfunction with network pharmacology-based strategy

Erectile dysfunction is considered an important health problem that impacts the quality of life of men. Yinyanghuo, also called Epimedium or Horny Goat Weed, is a frequently used Chinese traditional herbal medicine, commonly used in treating erectile dysfunction in China. A network pharmacology method was performed systematically, at a molecular level, to analyse the pharmacological mechanism of Yinyanghuo as erectile dysfunction therapy. The network pharmacology method used in this study primarily includes prescreening of the active compounds, prediction of targets, network analysis and gene enrichment analysis. This network analysis proved that 4 targets (AR, NR3C2, PDE5A and BMP2) could be the targets of Yinyanghuo therapy on erectile dysfunction. Besides, gene enrichment analysis predicted that Yinyanghuo might have a role in erectile dysfunction by regulating 10 molecular functions, 8 cellular components, 10 biological processes and 36 possible targets related to 10 signalling pathways. Our study demonstrated the molecular and pharmacological mechanisms of Yinyanghuo against erectile dysfunction with a holistic approach and demonstrated a powerful method for analysing pharmacological mechanisms and rational utilisation of Traditional Chinese Medicine clinically.     

经外环口以下途径显微镜下精索静脉结扎术治疗精索静脉曲张术后复发的疗效分析

目的分析精索静脉曲张(VC)术后复发的病因,探讨经外环口以下途径显微镜下精索静脉结扎术(MV)治疗复发VC的疗效。方法回顾性分析2015年4月至2019年4月青岛大学附属医院收治的16例VC术后复发患者的病例资料。中位年龄27(18~36)岁。5例既往曾行精索内静脉高位结扎术,11例曾行腹腔镜精索静脉结扎术;16例于术后1~3年复诊时诊断为VC复发。复诊病因包括婚后未育10例、阴囊疼痛12例,其中婚后未育合并阴囊疼痛者6例。本组16例复发后,术前评估VC临床分级Ⅲ级13例(左侧8例,双侧5例),Ⅱ级3例(均为左侧)。疼痛视觉模拟评分(VAS)中位值为2.5(0~4)分。彩色多普勒血流显像(CDFI)分度:Ⅲ度12例(左侧7例,双侧5例),Ⅱ度4例(均为左侧)。12例临床分级和CDFI分度均为Ⅲ级(度)者的左肾血管CDFI检查提示合并胡桃夹现象(NCP)。术前血清睾酮(16.2±4.9)nmol/ml,精子浓度(11.8±3.9)×10⁶/ml,前向运动精子比例(PR)(24.4±4.2)%。本组16例均行经外环口以下途径的MV手术。全麻,患者取平卧位。术中取腹股沟管外环口以下斜切口,分离显露精索,其下方插入纱布条并垫高。使用手术显微镜放大术野4~6倍,彻底结扎并切断扩张迂曲的精索外和精索内静脉所有分支,注意保护精索内动脉和淋巴管。术中11例仅行左侧MV手术,5例行双侧MV手术,所有患者术中均探及明显扩张迂曲的精索外及精索内静脉,通过MV手术可以清晰解剖并充分保护精索内动脉及淋巴管。术中每例平均结扎左侧精索外静脉(2.1±0.6)支、精索内静脉(10.1±1.1)支,解剖出左侧精索内动脉(1.3±0.5)支、淋巴管(3.0±1.0)支,结扎右侧精索外静脉(1.4±0.5)支、精索内静脉(6.6±0.5)支,解剖出右侧精索内动脉(1.4±0.5)支、淋巴管(2.6±0.5)支。记录患者术后6个月的VAS、阴囊触诊情况、CDFI、精液分析、血清睾酮等指标,并与术前比较。结果本组16例21侧MV手术均顺利完成。术后6个月复查,所有患者查体阴囊无明显迂曲血管团,Valsalva试验呈阴性。VAS中位值为0(0~2)分,较术前显著降低(Z=-2.994,P<0.05)。精子浓度(16.2±4.6)×10⁶/ml,PR(34.5±4.1)%,均较术前明显改善(P<0.05);血清睾酮水平(16.6±4.4)nmol/ml,较术前无显著变化(P>0.05)。复查CDFI提示精索内静脉无明显反流。16例术后随访期内均未发生睾丸萎缩、鞘膜积液等并发症。术后随访1~3年,10例因婚后未育就诊者中5例术后随访期内完成生育。结论VC术后复发与静脉漏扎有关,特别是对于Ⅲ级VC或合并NCP的VC患者,采用内环口以上的传统高位结扎术或腹腔镜手术极可能漏扎较细的精索内静脉和外环口以下水平的精索外静脉。经外环口以下途径的MV手术,通过彻底结扎精索内和精索外静脉,同时保护精索内动脉和淋巴管,不仅可有效避免VC术后复发及并发症,而且可以缓解阴囊坠痛症状和改善精液质量。
