ABSTRACT
Objective:This study evaluates the relationship between carcino-embryonic antigen (CEA) and carbohydrate antigen 153 (CA153) continuous and remarkable reduction after chemotherapy and no-imaging progression in patients with advanced breast can-cer. Methods: Medical records of 93 patients who received chemotherapy in the Oncology Department of the General Hospital of Shenyang Military Command were included in the retrospective analysis. A total of 188 CEA and CA153 serum data were collected from response evaluations that included 105 CEA cases and 139 CA153 cases. Predictive validity of serum CEA and CA153 was as-sessed for diagnosing no-imaging progression. Results:CEA was continuously reduced by 10%, with sensitivity of 54.1%and specificity of 95%. CA153 was continuously reduced by 40%, with sensitivity of 19.1%and specificity of 96.6%. Conclusion:Serum CEA and CA153 could be considered as response evaluation tools when they are continuously reduced by at least 10%and 40%, respectively.
ABSTRACT
Abstrct Objective To develop a new type of paste for external trauma or surgical incision.Methods The paste is consisted of 6 parts,which are outer package;stickiness-proof soft membrane;aeration absorption layer;sticking fixation surface;neodymium,iron,boron and lanthanon magnet;cuticle.Different sizes of paste are made to observed the clinical effect.Results The product can accelerate wound healing,lower wound infection rate,and release pain,reduce the formation and soften scar.Conclusion The new type paste is a relatively reliable wound dressing,which can be applied in relative department.
ABSTRACT
Objective To develop a new kind of tracheal catheter for large or medium -sized surgical anesthesia as a medical equipment of respiratory management,and to rescue the patients with anhelation of respiratory arrest,which is essential to first-aid treatment and will be widely used clinically.Methods The disposable non-toxic transparent plastic was adopted,which was reinforced by the spiral stainless steel wire with regular separations.The diameter of the tracheal catheter varied with the different models.The tracheal catheter was composed of the items put into the trachea when applied for anesthesia such as the inflatable bladder and liquid mouth,the ones connected with the anesthesia machine such as the ring lines regulating direction of the front end of the catheter,and the syringe adapters for the liquid and gas.Results The flexible,air-proof tracheal catheter,with its direction adjustable,injected the medicine through its front end.Conclusion The tracheal catheter can be used for intratracheal medication,and will be popularized clinically.
