目的对精索静脉曲张(Varicocele, VC)患者应用显微镜下精索静脉低位结扎术(以下简称低位结扎术),探讨其效果及对精子质量、性功能的影响。方法回顾性选取2020年1月—2022年12月三明市第二医院收治的86例VC患者的临床资料,根据手术方案分组,对照组43例行精索高位结扎术,观察组43例行低位结扎术,比较两组患者围术期指标、精子质量、并发症、性功能。结果观察组手术时间长于对照组,术中出血量、术后3 d疼痛视觉模拟评分、住院时间均优于对照组,差异有统计学意义(p均p均>0.05),术后两组精子质量相关指标比较,观察组优于对照组,差异有统计学意义(p均pp均>0.05),术后,观察组上述性功能评分指标均优于对照组,差异有统计学意义(p均<0.05)。结论对VC患者而言,显微镜下精索静脉低位结扎术具有较好应用前景,既能减轻术后疼痛,加速康复,还可提高精子质量,有效提高患者性功能,减少术后并发症发生,值得临床借鉴。

Background Oxidative Stress and p38 mitogen-activated protein kinase （p38MApK） play a vital role in renal fibrosis. pioglitazone can protect kidney but the underlying mechanisms are less clear. The purpose of this study was to investigate the effect of pioglitazone on oxidative stress and whether the severity of oxidative stress was associated with the phosphorylation level of p38MApK.

Most economically important tungsten(W)deposits are of magmatic-hydrothermal *** species and partitioning of W during fluid exsolution,considered to be the controlling factors for the formation of ore deposits,are thus of great significance to ***,this issue has not been well addressed mainly due to the significant difference in reported partition coefficients(e.g.,from strongly incompatible to strongly compatible)between fluid and melt(D_(W)^(fluid/melt)).Here,we used an in situ Raman spectroscopic approach to describe the W speciation,and to quantitatively determine the Dfluid/melt of individual and total W species in granite melts and coexisting Na2WO4 solutions at elevated temperatures(T;700–800C)and pressures(p;0.35–1.08 Gpa).Results show that WO_(4)^(2-)and HWO4are predominant W species,and the fractions of these two species are similar in melt and coexisting *** partitioning behaviors of WO_(4)^(2-)and HWO4are comparable,exhibiting strong enrichment in the *** total DW fluid/melt ranges from 8.6 to ***,DW fluid/melt decreases with rising T–p,indicating that shallow exsolution favors enrichment of W in evolved ***,Rayleigh fractionation modeling based on the obtained D_(W)^(fluid/melt)data was used to describe the fluid exsolution *** results strongly support that fluid exsolution can serve as an important mechanism to generate W-rich oreforming *** study also indicates that in situ approach can be used to further investigate the geochemical behavior of ore-forming elements during the magmatic-hydrothermal transition,especially for rare metals associated with granite and pegmatite.

Background： The application of second-generation constrained condylar knee （CCK） prostheses has not been widely studied. This retrospective study was carried out to evaluate the clinical and radiographic outcomes of a second-generation CCK prosthesis for complex primary or revision total knee arthroplasty （TKA）. Methods： In total, 51 consecutive TKAs （47 patients） were performed between June 2003 and June 2013 using second-generation modular CCK prostheses. The follow-up was conducted at 3~a day, 1% 6＇h, and 12~h months postoperatively and later annually. Anteroposterior （Ap）, lateral, skyline, and long-standing Ap radiographs of the affected knees were taken. The Hospital for Special Surgery （HSS） Knee Score, the Knee Society Knee Score （KSKS）, the Knee Society Function Score （KSFS）, and range of motion （ROM） were also recorded. Heteroscedastic two-tailed Student＇s t-tests were used to compare the HSS score and the Knee Society score between primary and revision TKAs. A value ofp 〈 0.05 was considered statistically significant. Results： Four knees （two patients） were lost to follow-up, and 47 knees （31 primary TKAs and 16 revision TKAs） had a mean follow-up time of 5,5 years. The mean HSS score improved from 51.1 ±15.0 preoperatively to 85.3 ± 8.4 points at the final follow-up （p 〈 0.05）. Similar results were observed in terms of the KSKS and KSFS, which improved from 26.0 ± 13.0 to 80.0 ± 12.2 and from 40.0 ± 15.0 to 85.0± 9.3 points, respectively （p 〈 0.05）. No significant difference in the HSS, KSKS, KSFS, or ROM was found between primary and revision TKAs （p 〉 0.05）. Two complications were observed in the revision TKA group （one intraoperative distal lemur fracture and one recurrence of infection） while one complication （infection） was observed in the primary TKA group. No prosthesis loosening, joint dislocation, patella problems, tibial fracture, or nerve injury were observed. Radiolucent lines were observed in 4% of the knees without progressive osteolysis. C

This article introduces the system and application of teaching software Of 《Key to theExercises of Mechanical Drawing》 (will soon be published by the High Education publishingHouse). In general, CAI software is intended to be used for watching and listening, but can't beoperated personally. In order to improve the teaching effect, we introduce interactive capabilities intothe software, give students the opportunities of doing hands-on practice, increase the informationcontent of teaching in unit time, and leave more thinking face for students.
