目的:探讨宁泌泰胶囊在促进5~20mm的上尿路结石输尿管软镜钬激光碎石术后残余结石的排出及并发症方面的效果。方法:回顾性分析重庆医科大学附属第一医院2023年2月至2023年5月接受肾或输尿管结石手术的患者。按照纳入研究的患者术后服用药物种类分为2组,分别为:宁泌泰组及对照组。观察的结局指标有结石排出率,结石排净率,同时比较2组术后第1天及第14天血尿和尿路感染情况。另外,本研究还对6项随机对照试验进行了荟萃分析,以验证结果。结果:回顾性研究的结果表明,宁泌泰组患者术后14d的结石排出率(P=0.024)和排净率(P=0.002)均高于对照组,而2组患者术后第一天和第14天尿液中红细胞计数及白细胞计数并不存在统计学上的差异。对6项已发表的随机对照试验进行荟萃分析的结果同样表明,宁泌泰组比对照组的结石排出率和排净率高。同时还得出宁泌泰组患者结石排出和排净都更快,发生肾绞痛和使用镇痛药物的概率也较低。结论:宁泌泰胶囊对促进泌尿系结石术后残余结石的排出存在一定效果,可以降低患者术后发生肾绞痛的风险,但对于降低患者术后尿路感染和血尿的风险仍需进一步研究。

Exclusive responsiveness to ultraviolet light (~3.2 eV) and high photogenerated charge recombination rate are the two primary drawbacks of pure TiO_(2). We combined N-doped graphene quantum dots (N-GQDs), morphology regulation, and heterojunction construction strategies to synthesize N-GQD/N-doped TiO_(2)/P-doped porous hollow g-C_(3)N_(4) nanotube (PCN) composite photocatalysts (denoted as G-TPCN). The optimal sample (G-TPCN doped with 0.1wt% N-GQD, denoted as 0.1% G-TPCN) exhibits significantly enhanced photoabsorption, which is attributed to the change in bandgap caused by elemental doping (P and N), the improved light-harvesting resulting from the tube structure, and the upconversion effect of N-GQDs. In addition, the internal charge separation and transfer capability of0.1% G-TPCN are dramatically boosted, and its carrier concentration is 3.7, 2.3, and 1.9 times that of N-TiO_(2), PCN, and N-TiO_(2)/PCN(TPCN-1), respectively. This phenomenon is attributed to the formation of Z-scheme heterojunction between N-TiO_(2) and PCNs, the excellent electron conduction ability of N-GQDs, and the short transfer distance caused by the porous nanotube structure. Compared with those of N-TiO_(2), PCNs, and TPCN-1, the H2 production activity of 0.1%G-TPCN under visible light is enhanced by 12.4, 2.3, and 1.4times, respectively, and its ciprofloxacin (CIP) degradation rate is increased by 7.9, 5.7, and 2.9 times, respectively. The optimized performance benefits from excellent photoresponsiveness and improved carrier separation and migration efficiencies. Finally, the photocatalytic mechanism of 0.1% G-TPCN and five possible degradation pathways of CIP are proposed. This study clarifies the mechanism of multiple modification strategies to synergistically improve the photocatalytic performance of 0.1% G-TPCN and provides a potential strategy for rationally designing novel photocatalysts for environmental remediation and solar energy conversion.
