Objective To construct,express and analysis the antitumor activity of anti-EGFR ScFv(HL-L-L),and analyze bioinformatics and characterize correlation spectroscopy.Methods EGFR ScFv(HL-L-L)gene was obtained by OVER LAPING technology and construction of prokaryotic expression vector pET-28a-c(+)-VH-L-L.After induced expression,target protein HL-L-L was purified by Ni column,and its tertiary structures was predicted with SWISS - MODEL;size distribution and zeta potential distribution of the target protein HL-L-L were characterized by NanoZSP;the inhibition effects of HL-L-L on breast cancer cell proliferation were studied with the method of pharmacology.Results Prokaryotic expression vector pET-28a-c(+)-VH-L-L was constructed successfully,high purity of protein HL-L-L was obtained,and successfully predicted its three-dimensional structure;the size was about 489.7 nm,and the Zeta potential was 38.1 ,negatively charged.It had a certain inhibition effect on MCF # 7 proliferation,compared with blank group,and the difference was significant(P<0.01 ).Conclusion This study successfully express all anthropogenic medicinal anti-EGFR ScFv(HL-L-L),which has significant inhibiting effect on breast cancer cell proliferation.It provides the foun dation for further development of small molecules of anti-EGFR antibody drug.

Objective To explore the mechanism that gold nanorods trigger apoptosis in cancer cells.Methods Gold nanorods was synthesized by gold seed growing method, and its characterization was detected; gold nanorods on cell proliferation-toxicity were evaluated by CCK-8 Kit and apoptosis were detected by flow; mitochondrial membrane potential were tested by JC-1 and activation of Caspase 9 and Caspase 3 were detected by western blot. Results The results found that gold nanorods had nontoxic to normal cells, but highly toxic to tumor cells; and with the increasing of gold nanorods’ working time, the percentage of apoptotic cancer cells was increasing; in addition to, normal cells’ mitochondrial membrane potential did not change, but cancer cells had a significant reduction in mitochondrial membrane potential.Conclusion This study proves that gold nanorods induce apoptosis through the mitochondrial apoptosis pathway.

Objective To investigate the impacts of prehospital endotracheal intubation on postoperative pulmonary infection in the patients with severe traumatic brain injury.Methods Retrospectively, the clinical data of 284 patients with severe traumatic brain injury admitted in the 97th Hospital of PLA from July 2007 to December 2012 were analyzed.The patients were classified into two groups according to the timing of endotracheal intubation, namely, prehospital intubation group and admission intubation group.The postoperative pulmonary infection incidence, occurrence time, and the duration of treatment of the two groups were studied.Results The incidences of postoperative pulmonary infection in patients intubated before and after admission were 38.0％ and 25.2％ respectively.Pulmonary infection occurred in the prehospital intubation group was at the (9.9 ± 0.6) d after admission, and in the admission intubation group was at the (11.6 ± 0.3) d after admission.The duration of treatment for postoperative pulmonary infection was (21.2 ± 7.2) days and (14.5 ± 9.0) days respectively.Compared with the patients intubated after admission, patients intubated before admission suffered higher incidence (P ＜ 0.05), earlier onset (P ＜ 0.05), and longer treatment duration of pulmonary infection (P ＜ 0.01).Conclusions Severe traumatic brain injury patients with prehospital endotracheal intubation are more susceptible to pulmonary infection.Avoiding the tracheal injury and bacterial contamination in the procedure could reduce the incidence of pulmonary infection.

Objective:To grasp the degree of coordinated development and spatial distribution characteristics of medical service prices,medical service capacity and regional economic level,so as to promote the benign and coordinated development of medical service prices and various systems.Methods:The entropy value method is used to calculate the comprehensive evaluation index of medical service price,medical service capacity and regional economic level in the sample provinces,and the coupling coordination degree model is used to analyze the degree of coupling coordination between medical service price,medical service capacity and regional economic level in the sample provinces,and carry out spatial autocorrelation analysis.Results:The price of medical services was moderately coupled to the capacity of medical services and the level of the regional economy,and there was moderate dependence between the systems;the price of medical services was poorly coordinated with the capacity of medical services and the level of the regional economy;the coordination between the current price of medical services in China and the capacity of medical services and the level of the regional economy did not have a spatial aggregation and radiation effect in space.Conclusion:Coordination between the price of medical services in China and the capacity of medical services and regional economic level needed to be strengthened urgently.Suggestion:The capacity of medical services should be quantitatively evaluated and the formation of medical service prices should be guided,the coordination and linkage between medical service prices and macroeconomic levels should be strengthened,and efforts should be made to enhance the regional equilibrium of China's medical service price policy.
