中医药治疗糖尿病周围神经病变的研究进展

糖尿病渐以年轻化的趋势呈现,糖尿病周围神经病变(DPN)是糖尿病最常见的慢性并发症之一,因其高致残率严重影响病患的生活品质。本文简单阐述糖尿病周围神经病变的病因,并就中医药的角度对该病的治疗概况进行综述,以期为临床诊治提供新见解和新研究策略。     

Intravesical Bacillus Calmette-Guérin Treatment Is Inversely Associated With the Risk of Developing Alzheimer Disease or Other Dementia Among Patients With Non–muscle-invasive Bladder Cancer

BackgroundThe immune system plays an important role in the pathogenesis of Alzheimer disease (AD), but it remains unclear whether bacillus Calmette-Guérin (BCG) may affect the risk of AD or not.MethodsUsing retrospective chart review, we collected data regarding demographics, comorbidities, cancer diagnosis, BCG treatment, and subsequent diagnosis of AD or other dementia in a racially/ethnically diverse cohort of patients with non–muscle-invasive bladder cancer (NIMBC) receiving treatment between 1984 and 2020 in the Bronx, New York. We used Cox proportional hazard models to examine association between BCG treatment and risk of incident AD or other dementia, adjusting for age, gender, race/ethnicity, and major comorbidities.ResultsIn our cohort of 1290 patients with NMIBC, a total of 99 (7.7%) patients developed AD or other dementia during follow-up. Patients who received BCG treatment (25%) had a 60% lowered incidence of AD or other dementia (adjusted hazard ratio [HR], 0.41; 95% confidence interval [CI], 0.21-0.80) in comparison to those who did not receive BCG. There was also suggestive evidence that the reduction in risk of AD or other dementia associated with BCG treatment was stronger in men (adjusted HR, 0.34; 95% CI, 0.15-0.81) but not in women (adjusted HR, 0.75; 95% CI 0.25-2.24). When we stratified the patients who received BCG by type of treatments, patients who received both induction and maintenance rounds of BCG had a further lowered incidence of AD or other dementia (HR, 0.23; 95% CI, 0.06-0.96) than patients who did not receive BCG.ConclusionsTo our knowledge, our study is one of the first to suggest that BCG treatment is associated with a reduced risk of developing AD or other dementia in a multiethnic population, independent of significant comorbidities. Larger cohort studies are needed to corroborate our findings.     

Effect of a Device-Free Compressed Shell Fixation Method on Hepatic Respiratory Movement: Analysis for Respiratory Amplitude of the Liver and Internal Motions of a Fiducial Marker

Purpose

Suppression of respiratory movement of the liver would be desirable for high-precision radiation therapy for liver tumors. We aimed to investigate the effect of our original device-free compressed shell fixation method and breathing instruction on suppression of respiratory movement. The characteristics of liver motion based on the movement of a fiducial marker were also analyzed.

A biological or a synthetic mesh in immediate breast reconstruction? A cohort-study of long-term Health related Quality of Life (HrQoL)

ObjectivesMeshes/matrices are commonly used in immediate breast reconstruction. There are few studies comparing biological and synthetic meshes and it is unknown what type of mesh gives the best long-term results. The aim of this study was to compare long-term health-related quality of life (HrQoL) and patient satisfaction in implant-based immediate breast reconstruction with a biological mesh (Surgisis®) with that of patients reconstructed with a synthetic mesh (TIGR ® Matrix Surgical Mesh).Material and methodsBoth cohorts were prospectively included and consecutively operated. Clinical data was collected. HrQoL was evaluated with EuroQoL-5 dimension – 3 levels questionnaire (EQ-5D-3L) and the Hospital Anxiety and Depression Scale (HADS) and the Breast-Q.Results and conclusionSeventy-one patients were operated on in the biological group and 49 in the synthetic group. The response rates were 75 and 84 per cent, respectively. Mean follow-up time was 74 months and 23 months, respectively. There were no statistical differences in satisfaction and quality of life between the two groups. Complications and radiation seem to lead to a lower satisfaction. Our findings could indicate that biological and synthetic meshes give an equal long-term result as regards patients’ perceived quality of life.     

高强度聚焦超声消融治疗子宫肌瘤时妊娠一例报告并文献复习

高强度聚焦超声(high-intensity focused ultrasound,HIFU)消融治疗子宫肌瘤作为一种新的非侵入性的治疗方式,已越来越广泛地用于子宫肌瘤的治疗。但是对于HIFU治疗时妊娠的处理及妊娠结局鲜有文献报道。本文报道1例HIFU消融治疗子宫肌瘤时妊娠的病例,结合文献复习,探讨子宫平滑肌瘤对妊娠的影响、子宫平滑肌瘤不同处理方式对妊娠的影响、HIFU消融治疗子宫肌瘤时机选择的问题、HIFU消融治疗子宫肌瘤若同时合并妊娠时胎儿去留的问题以及近期HIFU消融治疗子宫肌瘤后对流产手术操作的影响等,以期对HIFU治疗子宫肌瘤的适应证、选择合适的治疗时间及术后选择合适的妊娠时机展开讨论。     

Adjuvant chemotherapy could improve the survival of pulmonary sarcomatoid carcinoma: A systematic review and meta-analysis

BackgroundComplete surgical removal is currently considered to be the best treatment option for pulmonary sarcomatoid carcinoma (PSC) especially in early stage operable disease; however, the reported recurrence-free survival is low. Benefits of adjuvant chemotherapy in PSC patients are still controversial, and there is no obvious agreement on the optimal treatment modalities of this disease. Therefore, we aimed to investigate the prognosis in terms of overall survival (OS) in patients with PSC who received adjuvant chemotherapy.MethodsThe review protocol was registered in PROSPERO (CRD42022306084). Patients with PSC who underwent surgical therapy with or without adjuvant chemotherapy were included into the meta-analysis. Hazard ratios (HR) with 95% confidence intervals (CIs) for OS were pooled and ROBINS-I tool was used to assess risk of bias of the included studies.ResultsWe identified four retrospective cohort studies with 6768 records from MEDLINE, Embase, and CENTRAL databases up to 9th September 2021, and altogether 1835 patients were included to the analysis. The present meta-analysis shows that patients receiving adjuvant chemotherapy had a significantly longer OS than patients who underwent surgical treatment alone (HR = 0.5657, 95%CI: 0.4391–0.7290, p < 0.0001).ConclusionsDespite the limited information on the chemotherapy regimens in the included studies, patients with PSC may benefit from adjuvant chemotherapy. More publications are required to evaluate and compare efficient adjuvant chemotherapy protocols in PSC cases.
