This study aims to conduct a cost-effectiveness analysis of three different anesthesia strategies,namely chatting while under local anesthesia(Chat-LA),total intravenous anesthesia(TIVA),and general anesthesia with laryngeal mask airway(GA-LMA),employed in transperineal magnetic resonance imaging(MRI)/ultrasound(US)fusion prostate biopsy(TP-MUF-PB).A retrospective study was conducted involving 1202 patients who underwent TP-MUF-PB from June 2016 to April 2023 at The First Affiliated Hospital of Soochow University(Suzhou,China).Clinical data and outcomes,including total costs,complications,and quality-adjusted life years(QALYs),were *** sensitivity and subgroup analyses were also ***-LA was found to be the most cost-effective option,outperforming both TIVA and ***,subgroup analyses revealed that in younger patients(under 65 years old)and those with smaller prostate volumes(<40 ml),TIVA emerged as a more cost-effective *** Chat-LA may generally be the most cost-effective and safer anesthesia method for TP-MUF-PB,personalization of anesthesia strategies is crucial,considering specific patient demographics such as age and prostate volume.

Prostate-specific Antigen Density Variation Rate as a Potential Guideline Parameter for Second Prostate Cancer Detection Biopsy

引用

Chinese Medical Journal 2016年第15期129卷 1800-1804页

作者： Gan-Sheng Xie jin-Xing Lyv Gang Li Chun-Yin Yan Jian-Quan Hou jin-xian pu xiang Ding Yu-Hua Huang Department of Urology The First Affiliated Hospital of Soochow University Suzhou Jiangsu 215000 China

Background： The diagnostic value of current prostate-specific antigen （PSA） tests is challenged by the poor detection rate of prostate cancer （PCa） in repeat prostate biopsy. In this study, we proposed a novel PSA-related parameter named PSA density variation rate （PSADVR） and designed a clinical trial to evaluate its potential diagnostic value for detecting PCa on a second prostate biopsy. Methods： Data from 184 males who underwent second ultrasound-guided prostate biopsy 6 months after the first biopsy were included in the study. The subjects were divided into PCa and non-PCa groups according to the second biopsy pathological results. Prostate volume, PSA density （PSAD）, free-total PSA ratio, and PSADVR were calculated according to corresponding formulas at the second biopsy. These parameters were compared using t-test or Mann-Whitney U-test between PCa and non-PCa groups, and receiver operating characteristic analysis were used to evaluate their predictability on PCa detection. Results： PCa was detected in 24 patients on the second biopsy. Mean values of PSA, PSAD, and PSADVR were greater in the PCa group than in the non-PCa group （8.39 μg/L vs. 7.16 μg/L, 0.20 vs. 0.16, 14.15% vs. 1.36%, respectively）. PSADVR had the largest area trader the curve, with 0.667 sensitivity and 0.824 specificity when the cutoff was 10%. The PCa detection rate was significantly greater in subjects with PSADVR 〉10% than PSADVR _〈10% （28.6% vs. 6.5%, P 〈 0.001 ）. In addition, PSADVR was the only parameter in this study that showed a significant correlation with mid-to-high-risk PCa （r = 0.63, P = 0.03）. Conclusions： Our results demonstrated that PSADVR improved the PCa detection rate on second biopsies, especially for mid-to-high-risk cancers requiring prompt treatment.

Chronic Diseases and Translational Medicine 2016年第4期2卷 -页

作者： xiang Ding Song-Tao Xu Yu-Hua Huang Xue-Dong Wei Jiang-Lei Zhang Liang-Liang Wang jin-xian pu Jian-Quan Hou Chun-Yin Yan Feng-Mei Cui Department of Urology The First Affiliated Hospital of Soochow University Suzhou Jiangsu 215006 China Department of Clinical Medicine Luohe Medical College Luohe Henan 462002 China Department of Toxicology School of Radiation Medicine and Public Health Soochow University Suzhou Jiangsu 215123 China

Objective: To retrospectively evaluate appropriate treatment for patients with symptomatic caliceal diverticular calculi, by comparing the therapeutic outcomes for those undergoing minimally invasive percutaneous nephrolithotomy (MPCNL) and flexible ureterorenoscopy (F-URS). Methods: From March 2009 to May 2014, 36 consecutive patients with caliceal diverticular calculi were divided into 2 groups:21 patients underwent MPCNL, and 15 were treated by F-URS. All procedures were performed by one surgical group, which ensured relatively constant parameters. Patient characteristics, operative time, hospital stay after surgery, stone-free rate, symptomatic improvement rate, complications, diverticular obliteration, and stone composition were analyzed retrospectively in the 2 groups. Results: Patient preoperative variables were comparable between the two groups, with no significant difference (P>0.05). Mean operative time was 136.9 ± 22.8 min in the MPCNL group and 117.3 ± 24.3 min in the F-URS group (P ? 0.019). Hospital stay was significantly longer in the MPCNL group than in the F-URS group (9.4 ± 3.1 vs. 6.9 ± 2.1 days, P ? 0.010). The stone-free rates after MPCNL and F-URS were 90.5%(19/21) and 60.0%(9/15), respectively (P ? 0.046). Additionally, 71.4%(15/21) of patients in the MPCNL group and 46.7%(7/15) of patients in the F-URS group had symptomatic improvement at the 6-month follow-up (P ? 0.175);the rates of complications in the 2 groups were 19.0%(4/21) and 13.3%(2/15), respectively (P ? 0.650). Complete diverticular obliteration was achieved in 16 (76.2%) cases in the MPCNL group and 5 (33.3%) cases in the F-URS group (P ? 0.017). The distributions of calcium oxalate and hydroxyapatite in the stones were 66.7% (14/21) and 33.3% (7/21), respectively, in the MPCNL group;however, the distributions in the F-URS group were 46.7%(7/15) and 53.3%(8/15), respec-tively (P ? 0.310). Conclusion: MPCNL is an effective method for the treatment of caliceal diverticula

背景:细胞焦亡参与软骨细胞外基质降解、滑膜炎症以及疼痛,在骨关节炎防治中发挥重要作用。此外,运动可通过抑制细胞焦亡调控骨关节炎的发生,已成为防治骨关节炎的研究热点。目的:总结细胞焦亡在骨关节炎中的调控作用,以及运动介导细胞焦亡在改善骨关节炎中的机制。方法:以“pyroptosis,osteoarthritis,chondrocyte pyroptosis,synovial cell pyroptosis,exercise”和“细胞焦亡,骨关节炎,软骨细胞焦亡,滑膜细胞焦亡,运动”为关键词,检索pubMed与中国知网数据库1992-2024年间发表的相关文献,根据纳入及排除标准选择71篇文献进行综述。结果与结论:①骨关节炎是以软骨细胞外基质降解、滑膜炎症和软骨下骨重塑等为特点的慢性退行性关节疾病,易引起骨的器质性病变、疼痛并引发功能障碍。②细胞焦亡作为一种特殊的程序性死亡机制,其特征为细胞裂解死亡释放炎症因子引发强烈的炎症反应,与骨关节炎的发生发展关系密切。细胞焦亡可导致大量炎症因子释放,进而激活核因子κB转录,增加焦亡蛋白的产生,进而加剧骨关节炎的发生发展,因此细胞焦亡可作为骨关节炎防治的新方向。③运动可通过下调焦亡蛋白信号通路和抑制相关炎症因子表达等途径抑制软骨细胞和滑膜细胞的焦亡,从而在骨关节炎防治中发挥重要作用。有氧和无氧运动可通过抑制细胞焦亡的发生延缓骨关节炎的病理进程,中等强度的有氧运动通过抑制细胞焦亡信号通路改善骨关节炎的效果较好,无氧运动可通过提高肌肉质量进而对骨关节炎产生有益效应。

Optimization of Hot Workability in Superaustenitic Stainless Steel 654SMO

引用

Journal of Iron and Steel Research International 2014年第10期21卷 975-982页

作者： En-xiang pu Wen-jie ZHENG Zhi-gang SONG jin-zhong xianG xian-ping WEI School of Physics Science and Technology Yunnan University Central Iron and Steel Research Institute

Hot compression tests were conducted on a Gleeble-3800 machine in a temperature range of 950 to 1200 ℃ and a strain rate range of 0. 001 to 10 s-1 in order to study the hot deformation behaviour of superaustenitic stainless steel 654SMO. The results show that peak stress increases with decreasing temperature and increasing strain rate, and the apparent activation energy of this alloy was determined to be about 494 kJ/mol. The constitutive equation which can be used to relate the peak stress to the absolute temperature and strain rate was obtained. The processing maps for hot working developed on the basis of flow stress data and the dynamic materials model were adopted to op- timize the hot workability. It is found that the features of the maps obtained in the strain range of 0.2 to 1.0 are fun- damentally similar, indicating that the strain does not have a substantial influence on processing map. The combina- tion of processing map and mierostructural observations indicates that the favorable hot deformation conditions are located in two domains of processing map. The first domain occurs in the temperature range of 980 to 1035 ℃ and strain rate range of 0. 001 to 0.01 s-1 with a peak efficiency of 55%. The second domain appears in the temperature range of 1 120 to 1 180 ℃ and strain rate range of 0.3 to 3 s-1 with peak efficiency of 35%. Compared to other stable domains, the specimens deformed in these two domains exhibit full dynamic recrystallization grains with finer and more uniform sizes. An instability domain occurs at temperatures below 1 100 ℃ and strain rate above 0.1 s-1 , and flow instability is manifested in the form of flow localization.
