银杏黄酮甙和甲基B_(12)联合治疗糖尿病周围神经病变的疗效观察

目的　探讨银杏黄酮甙和甲基B12 对糖尿病周围病变的治疗效果。方法　将 14 9例糖尿病周围神经病变患者随机分为 4组 ,分别为常规治疗组 (对照组 )、银杏黄酮甙组 (第 1组 )、甲基B12 组 (第 2组 )、银杏黄酮甙与甲基B12 联合组(第 3组 )。疗程为 8周。观察治疗前后自觉症状、腱反射和神经传导速度。结果　第 3组总有效率为 95 % ,显著高于对照组 (17% ) (P <0 .0 0 5 )。第 1组和第 2组 ,总有效率分别为 6 9%和 72 % ,与对照组比较均有显著差异 (P <0 .0 1)。第 3组神经传导速度治疗后较冶疗前显著改善 (P <0 .0 1) ,而且显著优于对照组 (P <0 .0 1)、第 1组 (P <0 .0 5 )和第 2组 (P <0 .0 5 )。结论　银杏黄酮甙和甲基B12 联合治疗糖尿病周围神经病变较单独应用更为有效。     

市场均衡就业区间及其对社会就业的影响

现代市场经济运行中 ,厂商将其供给量调整到合理水平所需的费用可称为微观调节成本。由于存在微观调节成本这种特殊的经济运行费用 ,因而传统分析中宏观层面上市场就业均衡点的两侧便分别存在着“低位临界点”与“高位临界点” ,这两点界定了一个“市场均衡就业区间” ,社会就业一旦进入该区间 ,市场机制便不可能再对其作出调节。市场均衡就业区间的主要特点在于 ,其均衡是就区间外部而言的 ,在区间内部仍可以存在一定程度的就业失衡 ;市场均衡就业区间内部的就业失衡是一种特殊的就业失衡 ,市场机制对之无能为力 ,一般的宏观经济政策亦无法对其发生作用。市场均衡就业区间的存在对社会就业有着多方面的重要影响 ,它使社会就业对供求总量波动的反应呈现出一定“粘性” ;使市场机制对社会就业的调节空间减小 ;使政府调控社会就业的重点二元化 ;使个体经济在缓解就业失衡压力、扩大社会就业方面占有了特殊重要的地位。

Clinicopathological characteristics,prognosis, and chemosensitivity in patients with metastatic upper tract urothelial carcinoma

PurposeTo investigate the clinical characteristics, chemosensitivity, and outcome of metastatic upper tract urothelial carcinoma (UTUC).Patients and MethodsRecords of patients with metastatic UTUC since January 2005 were retrieved from a database that included clinical and survival data. Statistical analyses including survival and multivariate analyses of factors were respectively performed by the Kaplan-Meier method and Cox proportional hazard model.ResultsA total of 250 consecutive UTUC cases were evaluated. There were 56 patients (22.4%) with initially diagnosed stage IV disease. The most common metastatic sites were lung (39.6%), distant lymph nodes (39.2%), bone (19.6%), liver (18.0%), and adrenal gland (7.2%), respectively, and the local recurrence rate was 10.4%. Two hundred thirteen patients received first-line chemotherapy. The overall response rate was only 28.7% and the median progression-free survival time was only 5.0 months. The overall survival time of the cohort was 18.0 months. Multivariate analyses showed that initially diagnosed stage IV disease, number of metastatic organs ≥3, no response to chemotherapy and cycles of chemotherapy ≤2 were adverse prognosticators for overall survival.ConclusionUTUC presented to be more prone to metastasize than locally recur and thought to have low chemosensitivity. Stage IV disease at initial diagnosis, number of metastatic organs, response and cycles of chemotherapy were independent prognosticators for metastatic UTUC.     

Adverse events involving hallux metatarsophalangeal joint implants: Analysis of the United States Food and Drug Administration data from 2010 to 2018

BackgroundThe prevalence of osteoarthritis of the hallux metatarsophalangeal joint (MTPJ) is 1 in 40 people over the age of 50. Surgical treatment options for MTPJ arthritis include joint preservation, joint resurfacing, and arthrodesis. Hallux MTPJ implants have evolved over the past several decades, but are associated with various complications. The aim of this study was to examine the MAUDE database to determine reported adverse events for hallux MTPJ implants.Materials and methodsThe US Food and Drug Administration’s (FDA) Manufacturer and User Facility Device Experience (MAUDE) database was reviewed from 2010 to 2018 to review voluntary reported adverse event reports for approved implants within the United States. We recorded the type of adverse event and excluded duplicate reports and those extracted from already published literature.ResultsAmong 64 reported hallux MTPJ implant adverse events, the most common modes of adverse events were component loosening (34%), infection (14.1%), component fracture (9.4%), inflammation (9.4%), and allergic reaction (7.8%). Regarding implant type, Cartiva SCI had the highest percentage of adverse events (23.4%), followed by Arthrosurface ToeMotion (20.3%), Ascension MGT (12.5%), Arthrosurface HemiCAP® (10.9%), Futura primus (9.4%), and Osteomed Reflexion (6.3%). There was an increase in reported adverse events after 2016. The MAUDE database does not report the total incidence of implant insertion.ConclusionOur study of the MAUDE database demonstrated that component loosening and infection are the most common modes of adverse events for hallux MTPJ implants. Cartiva accounted for one-fourth of the implant-related adverse events during our study period, followed by ToeMotion, and Ascension MGT implants. Continued reporting of adverse events will improve our understanding on short and long-term complications of various hallux MTPJ implants.Level of evidenceLevel IV; Case Series from Large Database Analysis; Treatment Study.
