1.Splint versus plaster cast external fixator for the treatment of distal forearm buckle fracture in children:systematic review
Chinese Journal of Tissue Engineering Research 2014;(13):2113-2118
BACKGROUND:The distal forearm buckle fracture in children has no secondary displacement risk, and the literatures have reported that the fracture can be treated with external fixators of plaster cast, palm side plate, splint, brace and bandage, and obtain good effect. But different external fixators have different effects on the functional recovery and viability.
OBJECTIVE:To assess the clinical efficacy and safety of splint versus plaster cast for the treatment of distal forearm buckle fracture in Children.
METHODS: The Medline database, Embase database, Cochrane Library, CNKI database and CBM database were searched from the database establishment to April 2011 with the computer;the relative conference papers were hand searched;the Important Clinical Trial Register was searched online without limitation of language. Randomized control ed trials and quasi-randomized control trials were selected for quality evaluation, and the Meta-analysis was performed with Revman 5.1. RESULTS AND CONCLUSION:Two published trials including a total of 314 patients were included, and one randomized control ed trial was evaluated as B scale, another one quasi-randomized control trial was evaluated as C scale. The results demonstrate that no fracture, un-union or re-fracture occurred after treated with splint and plaster case external fixator, and there were no significant differences in pain scores as wel as the daily activities of writing, drawing, self-eating and washing;while the early bathing ability of the patients in the splint group was earlier than that in the plaster cast group, and had no significant difference in the advanced bathing ability. The regular exercise participation in the splint group was better than that in the plaster cast group. There were no significant differences in the incidence of adverse events between two groups. The results indicate that the pain score of the patients with distal forearm buckle fracture in children do not improved after treated with splint and plaster cast, but splint fixation is better than plaster cast fixation in maintaining the batching and regular exercise participation ability with good safety. But the wel-designed and implement large sample and multi-center randomized control ed trials are needed for validation.
2.Application value of combination detection of tumor markers in diagnosis and differential diagnosis of lung cancer
International Journal of Laboratory Medicine 2014;(16):2171-2173
Objective To investigate the application value of 6 kinds of tumor markers serum neuron-specific enolase(NSE),cy-tokeratin 19 fragment(Cyfra21-1),carbohydrate antigen 19-9(CA19-9),carbohydrate antigen 12-5(CA12-5),squamous cell carcino-ma antigen(SCC-Ag),carcino embryonic antigen(CEA)in the diagnosis and differential diagnosis of lung cancer.Methods Serum NSE,Cyfra21-1,CA19-9,CA12-5,SCC-Ag and CEA levels were detected in 140 cases of lung cancer,57 cases of benign lung disea-ses and 45 individuals with healthy physical examination as control group by electrochemiluminescence immunoassay.The values of these 6 kinds of tumor marker in the diagnosis and the differential diagnosis of lung cancer were observed.Results The levels of CA12-5,CA19-9 and CEA in the lung cancer group were significantly higher than those in the benign lung diseases group and the healthy physical examination group(P <0.05 ),the sensitivity and accuracy in the combined detection of the six kinds of tumor marker in diagnosing lung cancer were 95.2% and 89.7% respectively,which was superior to those in single index detection.Con-clusion The tumor makers need to be jointly detected,which can increase the sensitivity and accuracy for diagnosing lung cancer and conduces to the differential diagnosis of early lung cancer.
3.Function of tumor-associated macrophages in gastric cancer
Chinese Journal of Clinical Oncology 2013;(20):1261-1263
Macrophages are a diverse phenotype that has important functions in inherent and adaptive immunity. Macrophage ac-tivation has two distinct states of polarization:the classically activated (M1) and the alternatively activated (M2) macrophage pheno-types in different micro-environments. M2 macrophages exert an immuno-regulatory activity that is associated with the induction of Th2 responses. The macrophages can infiltrate in the tumor micro-environment, and is also known as tumor-associated macrophages (TAMs). TAMs show the M2 macrophage phenotypes that have been associated with tumor neo-vascularization, infiltration, and metas-tasis. This review aims to investigate the importance of the immuno-regulatory activity of TAM in the carcinogenesis of gastric cancers.
