Carcinoma‐associated fibroblasts,its implication in head and neck squamous cell carcinoma: a mini review

The communication between tumor stromal and parenchymal cells provides an insight to tumor progression. One of the main elements of the stroma, a major contributor to the extracellular environment of tumors, is carcinoma‐associated fibroblasts. They can originate from either normal fibroblasts in the immediate vicinity of the tumor or from circulating bone marrow–derived mesenchymal stem cells. These myofibroblasts can arise locally from an endothelial–mesenchymal transformation at the invasive edge of the cancer and are physically associated with carcinoma cells, that is, in the development of high‐grade malignancies and poor prognosis. These carcinoma‐associated fibroblasts feed the epithelial tumor cells in a host–parasite relationship establishing its role in head and neck squamous cell carcinoma progression.     

Influence of bismuth oxide concentration on the pH level and biocompatibility of white Portland cement

Objectives

To investigate if there is a relation between the increase of bismuth oxide and the decrease of pH levels and an intensification of toxicity in the Portland cement.

Material and Methods

White Portland cement (WPC) was mixed with 0, 15, 20, 30 and 50% bismuth oxide, in weight. For the pH level test, polyethylene tubes were filled with the cements and immersed in Milli-Q water for 15, 30 and 60 days. After each period, the increase of the pH level was assessed. For the biocompatibility, two polyethylene tubes filled with the cements were implanted in ninety albino rats (n=6). The analysis of the intensity of the inflammatory infiltrate was performed after 15, 30 and 60 days. The statistical analysis was performed using the Kruskal-Wallis, Dunn and Friedman tests for the pH level and the Kruskal-Wallis and Dunn tests for the biological analysis (p<0.05).

Results

The results showed an increase of the pH level after 15 days, followed by a slight increase after 30 days and a decrease after 60 days. There were no significant statistical differences among the groups (p>0.05). For the inflammatory infiltrates, no significant statistical differences were found among the groups in each period (p>0.05). The 15% WPC showed a significant decrease of the inflammatory infiltrate from 15 to 30 and 60 days (p<0.05).

Conclusions

The addition of bismuth oxide into Portland cement did not affect the pH level and the biological response. The concentration of 15% of bismuth oxide resulted in significant reduction in inflammatory response in comparison with the other concentrations evaluated.     

化疗联合HLA不全相合G-PBSC输注治疗恶性血液病的临床分析

目的初步探讨化疗联合HLA不全相合G-PBSC输注(微移植)治疗恶性血液病的临床应用。方法回顾性分析2015-05～2016-12接受微移植治疗的13例恶性血液病患者的临床及随访资料。根据病情,对13例患者行不同的预处理方案化疗后,计划给予微移植3～4次。观察微移植后患者的缓解情况,生存时间,血象恢复时间,急、慢性移植物抗宿主病(GVHD)及其他不良反应发生情况。结果随访至2017-04,中危组8例,其中存活6例,死亡2例;高危组5例,其中存活2例,死亡3例。中位生存期为9个月(4～24个月)。微移植治疗后,中性粒细胞和血小板平均恢复时间分别为8 d(5～14 d)和11 d(6～20 d)。所有患者在微移植过程中均未出现急、慢性GVHD及其他不良反应。结论微移植在供者选择上不受限制,移植后血小板及中性粒细胞恢复较快,且无急、慢性GVHD及其他不良反应发生;微移植在中高危恶性血液病的临床应用尚处于探索阶段,仍需多中心、大样本的临床研究来进一步验证。     

燕滨扶正胶囊治疗代偿期及失代偿期肝硬化临床疗效观察研究

目的 研究中药燕滨扶正胶囊治疗肝硬化（代偿期或失代偿期）临床疗效。方法 选择代偿期及失代偿期肝硬化患者41例,随机分为治疗组（21例）及对照组（20例）。治疗组给予燕滨扶正胶囊1500 mg/次,口服,2次/日。对照组给予扶正化瘀胶囊2500 mg/次,3次/日。两组疗程均为48周。两组依据病情给予抗病毒,护肝降酶、对症支持等一般治疗（替比夫定、甘利欣、消炎利胆片、茵栀黄胶囊等）,观察两组患者症状、血常规、肝功能、门静脉宽度、腹水、肝脏及脾脏形态。结果 中药燕滨扶正胶囊联合抗病毒药物可使代偿期及失代偿期肝硬化患者门静脉宽度、脾肿大回缩或复常,可使纤维化指标复常或大幅下降且肝脏功能好转或复常。结论 燕滨扶正胶囊可改善肝硬化。
