Abstract

OBJECTIVE:Rapid on-site evaluation has long been used for transbronchial needle aspiration or fine-needle aspiration to evaluate the adequacy of biopsy materials for the diagnosis of peripheral lung lesions. However, research on rapid on-site evaluation combined with transbronchial forceps biopsy in the diagnosis of lung carcinoma is rarely reported. Therefore, we aimed to investigate the value of rapid on-site evaluation during transbronchial forceps biopsy for endoscopically visible (tumor, infiltrative and necrotic) or nonvisible (compressive, nonspecific and normal) malignancy. METHODS:A retrospective analysis was performed between January 2015 and January 2019 in Taihe Hospital with 1216 lung cancer patients who underwent bronchoscopy procedures, and these patients were allocated into the rapid on-site evaluation group and non-rapid on-site evaluation group, depending on the timing of the procedure. According to endoscopic features, bronchoscopic appearance was described as endoscopically visible malignancy (tumor, infiltrative and necrotic) and endoscopically nonvisible malignancy (compressive, nonspecific and normal). The diagnostic yield was compared, and the concordance between the rapid on-site evaluation results and the final histology was analyzed. RESULTS:There was a statistically significant difference in the diagnostic yield between the rapid on-site evaluation and non-rapid on-site evaluation groups for endoscopically nonvisible malignancy (74.3% vs. 51.7%, P < 0.05). However, we found no significant improvement in terms of diagnostic yield for endoscopically visible malignancy (95.2% vs. 91.2%, P > 0.05). The rapid on-site evaluation results showed high-level concordance with histology in the diagnosis of squamous cell carcinoma, adenocarcinoma and small cell carcinoma, with kappa values of 0.749 (P < 0.05), 0.728 (P < 0.05) and 0.940 (P < 0.05), respectively. CONCLUSIONS:The findings demonstrated that the diagnostic yield of transbronchial biopsy for endoscopically nonvisible malignancy (compressive, nonspecific and normal) was significantly improved when rapid on-site evaluation was implemented. In addition, the rapid on-site evaluation results had high-level concordance with the final histological diagnosis.

摘要

目的: 长期以来,快速现场评估一直用于经支气管针吸活检或细针穿刺活检,以评估活检材料对肺周围病变诊断的充分性。然而,快速现场评估联合经支气管钳活检在肺癌诊断中的研究鲜有报道。因此,我们的目的是研究在经支气管钳活检期间快速现场评估内镜下可见 (肿瘤,浸润性和坏死性) 或不可见 (压迫性,非特异性和正常) 恶性肿瘤的价值。 方法: 回顾性分析2015年1月至2019年1月在太和医院行支气管镜检查的1216例肺癌患者,根据手术时机将这些患者分为快速现场评估组和非快速现场评估组。根据内镜特征,支气管镜外观被描述为内镜可见的恶性肿瘤 (肿瘤,浸润性和坏死性) 和内镜不可见的恶性肿瘤 (压迫性,非特异性和正常)。比较诊断率,分析快速现场评估结果与最终组织学的一致性。 结果: 快速现场评估组和非快速现场评估组对内镜下不可见恶性肿瘤的诊断率差异有统计学意义 (74.3% 对51.7%,P <0.05)。然而,我们发现内镜下可见恶性肿瘤的诊断率没有显著提高 (95.2% 对91.2%,P> 0.05)。快速现场评估结果显示,鳞癌、腺癌和小细胞癌的诊断与组织学高度一致,kappa值分别为0.749 (P < 0.05) 、0.728 (P < 0.05) 和0.940 (P <0.05)。 结论: 研究结果表明,当实施快速现场评估时,经支气管活检对内镜下不可见恶性肿瘤 (压迫性、非特异性和正常) 的诊断率显著提高。此外,快速现场评估结果与最终组织学诊断具有高度一致性。

METHODS::The ATP binding-cassette superfamily corresponds the mostly transmembrane transporters family found in humans. These proteins actively transport endogenous and exogenous substrates through biological membranes in body tissues, so they have an important role in the regulation of many physiological functions necessary for human homeostasis, as well as in response regulation to several pharmacological substrates. The development of multidrug resistance has become one of the main troubles in conventional chemotherapy in different illnesses including cancer, being the increased efflux of antineoplastic drugs the main reason for this multidrug resistance, with a key role of the ABC superfamily. Likely, the interindividual variability in the pharmacological response among patients is well known, and may be due to intrinsically factors of the disease, genetic and environmental ones. Thus, the understanding of this variability, especially the genetic variability associated with the efficacy and toxicity of drugs, can provide a safer and more effective pharmacological treatment, so ABC genes are considered as important regulators due to their relationship with the reduction in pharmacological response. In this review, updated information about transporters belonging to this superfamily was collected, the possible role of these transporters in cancer, the role of genetic variability in their genes, as well as some therapeutic tools that have been tried to raise against main transporters associated with chemoresistance in cancer.

METHODS:BACKGROUND:Cholinergic neurotransmission regulates neuroinflammation in Parkinson disease (PD). RESEARCH DESIGN AND METHODS:The authors conducted a delayed-start study of donepezil for cognitive decline in non-demented PD patients. The study consisted of a 96-week randomized placebo-controlled double-blind phase 1, followed by a 24-week donepezil extension phase 2. The primary outcome measure was a change in the Mini-Mental State Examination (MMSE) at week 120. RESULTS:A total of 98 patients were randomly allocated to the early-start (donepezil-to-donepezil) and delayed-start (placebo-to-donepezil) groups. Mean (SD) of the baseline MMSE was 27.6 (2.0) and 28.0 (2.1), respectively. MMSE change at week 120 was better in the early-start group than in the delayed-start group, but the difference was not significant. The MMSE declined in apolipoprotein ε4 carriers, but not in non-carriers, and the factor interaction (intervention × ε4 genotype) was highly significant (P < 0.001). Analyzed with the interaction, the difference was significant (group difference 1.95 [0.33 to 3.57], P = 0.018). The MMSE decline slope in phase 1 was significantly better in the early-start group than in the delayed-start group (P = 0.048). CONCLUSIONS:Cognitive function deteriorated in ε4 carriers, but not in non-carriers, and early-start donepezil may postpone cognitive decline in the former.

METHODS::Since the discovery of dental pulp stem cells, a lot of teams have expressed an interest in dental pulp regeneration. Many approaches, experimental models and biological explorations have been developed, each including the use of stem cells and scaffolds with the final goal being clinical application in humans. In this review, the authors' objective was to compare the experimental models and strategies used for the development of biomaterials for tissue engineering of dental pulp with stem cells. Electronic queries were conducted on PubMed using the following terms: pulp regeneration, scaffold, stem cells, tissue engineering and biomaterial. The extracted data included the following information: the strategy envisaged, the type of stem cells, the experimental models, the exploration or analysis methods, the cytotoxicity or viability or proliferation cellular tests, the tests of scaffold antibacterial properties and take into account the vascularization of the regenerated dental pulp. From the 71 selected articles, 59% focused on the "cell-transplantation" strategy, 82% used in vitro experimentation, 58% in vivo animal models and only one described an in vivo in situ human clinical study. 87% used dental pulp stem cells. A majority of the studies reported histology (75%) and immunohistochemistry explorations (66%). 73% mentioned the use of cytotoxicity, proliferation or viability tests. 48% took vascularization into account but only 6% studied the antibacterial properties of the scaffolds. This article gives an overview of the methods used to regenerate dental pulp from stem cells and should help researchers create the best development strategies for research in this field.
