Objective To analyze the biological characteristics and morphologic features between the mouse models using MDA-MB-231 cells established by injecting tumor cell suspension or implanting tumor tissues. Methods Twenty BALB/c mice were randomly divided into two groups,with 10 in each group.The orthotopic models of breast cancer were established by injection of tumor cell suspension or implantation of tumor tissues in the fat pad of right second breast in the nude mice of the two groups,respectively.The time of tumor formation,success rate,tumor growth rate,shape,central tumor necrosis,blood vessel distribution and tumor ulceration were compared between the two groups of models.The histological features of the tumors were also observed. Results There were no significant difference in the success rate between the two methods.In the group of tumor tissues implantation,the tumors formed in an earlier time with various shape configurations,and they were hypovascular and vulnerable to central necrosis with the resultant superficial ulcerations.However,in the group with injection of tumor cell suspension,the tumors formed later with a regular shape,and the superficial ulceration was rare and not vulnerable to central tumoral necrosis since the tumors were abundant in blood vessels resulting in adequate nourishment.There were no significant difference in the pathological findings between the two groups. Conclusion The nude mouse models of breast cancer can be successfully established by both tumor tissues implantation and tumor cell suspension injection,with identical biological characteristics and fairly different morphological features.The investigators are well advised to choose the more appropriate one according to the purpose of the experiments.

In order to realize standardization and automatization,it necessary to develop a device for B→O blood conversion.This paper emphasizes on the control system of B→O blood conversion device,including software and hardware design,which provides a safe and rapid method for B→O blood conversion.

B→O blood conversion has very important meanings in the blood transfusion during the period of peace and war.In the leader of Professor Zhang Yangpei,from Academy of Military Medical Sciences,B→O blood conversion has been achieved by using gene engineering.They obtained the great breakthrough in the domain of blood type conversion.In order to realize standardization and automatization,it is necessary to develop a device applying to B→O blood conversion.This device automatically accomplishes the process of B→O blood conversion,shortens the time of B→O blood conversion to quarter than the time by manual operation,and ensures the standardization and obturation.In the condition of one-off pipeline,this device meets the clinical demands for blood,and lays a foundation for clinical expansion of B→O blood conversion.This paper presented the control system of B→O blood conversion device,including design of software and hardware.This device provides a safe and efficient tool for B→O blood conversion.

BACKGROUND:Kunming mouse embryonic fibroblasts are the most common feeder layers at present, and there are rare reports addressing C57BL/6 mouse embryonic fibroblasts as feeder layers.
OBJECTIVE:To separate and culture C57BL/6 mouse embryonic fibroblasts in vitro, and produce feeder layers to enlarge the resources of mouse embryonic fibroblasts.
METHODS:C57BL/6 mouse embryonic fibroblasts were isolated and cultured by trypsin digestion method in vitro. The biological characteristics and growth rule of the fibroblasts were investigated, then the feeder layers for the cel culture were produced. The growth of cel colonies on the prepared feeder layer was tested.
RESULTS AND CONCLUSION:C57BL/6 mouse embryonic fibroblasts grew wel with a large amount, by trypsin digestion method at different concentrations. There was no significance in the survival rate after cryopreservation for 1 week, 2 weeks, 1 month, 3 months and 6 months. The cel s were proliferative from the second to fifth passage and declined sharply after the sixth passage. The planted mouse embryonic fibroblasts feeder layers had a high activity within 3 days, but got a sharp decline after 4 days. So it is best to use C57BL/6 mouse embryonic fibroblast feeder layers within 3 days after they’re inactivated. C57BL/6 mouse embryonic fibroblast feeder layer can support embryonic stem cel s and induce pluripotent stem cel s to grow as Kunming mouse embryonic fibroblasts.

Objective To study the prognosis of patients with unstable angina in PCI adverse events factor analysis,and the function of CYP2C 19 gene mutations.Methods From May 2013 to May 2015,226 cases of PCI postoperative patients,after surgery all took aspirin + clopidogrel maintenance to treat for 1 years,analyzed CYP2C19*1,CYP2C19*2,CYP2C19 *3 genotype with fluorescent polymerase chain reaction (PCR),the patients were followed up for 6 months.According to the result of detection of genotype divided into wild type group (CYP2C19 *1/*1),the mutation of mixed group (CYP2C19 *1/*2 and CYP2C19 *1/*3) group and mutations in pure form group (CYP2C19 *2/*2 and CYP2C19 *3/*3).Observed the occurrence of unstable angina of three groups prognosis.Results The mutation of mixed to form and mutation of pure form had a record of hospital clinical adverse events (61.9％ and 45.3％) was significantly higher risk of wild group (42.4％),with statistical significance (P ＜0.05);Logistic regression analysis of diabetes and CYP2C19 genotype with PCI postoperative patients with unstable angina occurred in hospital records of clinical adverse events had good correlation (R =3.424,P=0.009 and R =5.679,P =0.001).Conclusion The CYP2C19 gene mutations and diabetes patients with unstable angina PCI postoperative prognosis is closely related,the lack of CYP2C19 gene type are more likely to affect the prognosis of unstable angina,provide reliable basis for further research.

Objective To discuss drug resistance of wound-isolated pseudomonas aeruginosa and its correlation with use of antibiotics in children,for guiding the clinical use of antibiotics.Methods One hundred and forty wounded children admitted from January 2009 and December 2013 were collected in the study.There were 97 males and 43 females,aged (5.4 ± 2.6) years.All were victims of road traffic accidents.Distribution of bacteria isolated from the wound and drug resistance of pseudomonas aeruginosa were detected.Twenty-seven children with pseudomonas aeruginosa infection were divided into imipenem-resistant group (n =7) and non-imipenem resistant group (n =20).Drug resistance and application intensity of antibiotics were compared between the two groups.Results A total of 64 pathogens were isolated from the wound culture.Top five bacteria detected were acinetobacter baumannii,pseudomonas aeruginosa,enterobacter cloacae,escherichia coli and staphylococcus epidermidis.Pseudomonas aeruginosa showed resistance to β-lactam antibiotics,tetracyclines,chloram-phenicol and sulfanilamide.Drug resistance of piperacillin tazobactam (64.7％),meropenem (100％),ceftazidime (64.7％) and piperacillin (76.5％) in imipenem-resistant group were all 40％ higher than that in nonimipenem resistant group (P ＜ 0.05).Imipenem-resistant group versus non-imipenem resistant group revealed no significant differences in drug resistant rate of azactan (76.5％,39.0％),cefepime (70.6％,29.3％) and gentamicin (35.3％,17.1％) (P ＞ 0.05).There was no significant difference in total application intensity of antibiotics between the groups (P ＞ 0.05).Conclusions Wound-isolated pseudomonas aeruginosa in children is multidrug resistant.Thus bacterial monitoring in children with traumatic wounds should be strengthened and antibiotics should be selected rationally to reduce the production of multidrug resistance of pseudomonas aeruginosa.
