2.Applications of Porous Scaffolds in Muscle Tissue Engineering.
Journal of Biomedical Engineering 2015;32(6):1343-1347
Scaffold is one of the key elements required for tissue engineering. Porous scaffolds have several special advantages for muscle tissue engineering, and they are beneficial to cell survival, myogenic differentiation, and vascular ingrowth. The performance of porous scaffolds is closely related to the property of the biomaterials used. Additionally, the pore size and porosity may affect cell adhesion, proliferation, and differentiation. This review focuses on the application of porous scaffolds in muscle tissue engineering, including their categories, application, and advantages.

Objective To examine the impact of oncology nurses' compassion satisfaction and compassion fatigue on doctor-patient relationship satisfaction.Methods Questionnaire survey was conducted by 388 oncology nurses,the questionnaires include Professional Quality of Life Scale and DoctorPatient Relationship Satisfaction Scale.Results The total scores of compassion satisfaction was 34.22±7.19,the total scores of secondary traumatic was 26.32±6.12,the total scores of job burnout was 25.13±6.08,the total scores of doctor-patient relationship satisfaction was 4.24±0.75.Pearson correlation analysis showed that doctor-patient relationship satisfaction score was positively correlated with oncology nurses' compassion satisfaction (r=0.468,P < 0.05),negatioely correlated with nurses' compassion fatigue factor scores (r=-0.182,-0.531).Regression analysis showed that compassion satisfaction,secondary traumatic,job burnout and night shift frequency were influencing factors of doctor-patient relationship satisfaction,which could explain29.2% of the variance.Conclusions Improvement of the oncology nurses' compassion satisfaction and compassion fatigue can improve the doctor-patient relationship satisfaction and the quality of nursing service,and create a harmonious medical environment.

Medicinal properties are specific attributes of traditional Chinese medicines(TCM). The medicinal property theory is an important principle for the compatibility of traditional Chinese medicines. In this paper, medicinal properties, flavors and meridian tropism were combined to represent TCM medicinal properties; and multiple medicinal properties were further combined into medicinal property combination modes. TCMs and medicinal property combination modes were divided according to their efficacies, which were regarded as the concept of inductive logic programming and finally got medicinal property combination and compatibility rules with different efficacies. These medicinal property combination and compatibility rules were used to form the theoretical model through the entity grammar system, realize the automatic reasoning process from the medicinal property combination and compatibility to the efficacies, verify the reasoning result and analyze their rationality and limitations, in order to provide new ideas for revealing the relations between the TCM compatibility rules and efficacies.

OBJECTIVE:To evaluate the rationality of vancomysin use in the hospital where the authors work.METH-ODS:50patients taking vancomysin between May.2005and Nov.2005were studied.The pathogenic examination,monitoring of drug concentration in blood,indices of renal function,combined use of drugs as well as adverse effects in these patients were reviewed and analyzed statistically.RESULTS:On the whole vancomysin use in our hospital was safe.CONCLUSION:Vancomysin use will be made safer by monitoring drug concentration in blood,individualizing drug administration,and timely correcting the aggravating factors of kidney injury.

Objective To investigate the value of nuchal translucency(NT) thickening in the fetal chromosome abnormality screening.Methods The 14 881 pregnant women received NT measurement in 11-13 +6 weeks at Beijing Obstetrics and Gynecology Hospital from January 2010 to August 2012.The 118 fetuses whose NT≥2.5 mm were recruited.One hundred and eight (91.5%,108/118)of them accepted invasive procedure and karyotype analysis.Results (1) Chromosome karyotype analysis:113 singleton pregnancies (95.8%) and 5 twin pregnancies (4.2%) whose NT thickened from 2.5 mm to 11.0 mm were advised karyotype analysis.The 108 pregnant women accepted karyotype analysis.Among them,88 had normal chromosome karyotype,and 20 had chromosome abnormalities.The detection rate was 18.5 % (20/108).(2) The sensitivity,specificity,false positive rate,false negative rate,total consistent rate,positive predictive value and negative predictive value of prenatal screening of chromosome abnormalities for NT ≥ 2.5 mm were 44%,99%,1%,56%,99%,19% and 100%,respectively.(3) Among the 88 fetuses who had normal karyotype,72 (82%) had isolated thickened NT,while 16 (18%) had fetal structural malformation or intrauterine demise.(4) Among the 10 pregnant women who did not accept fetal karyotype analysis,8 terminated pregnancy because of fetal structural malformation,and the other 2 fetuses died in uterus.(5)All of the 5 twin pregnancies were dichorionic twins,and one of the twins had thickened NT.Among the 5 twin pregnancies,one fetus was trisomy 21 and others had normal karyotype.3 twin pregnancies who had normal chromosomes gave live birth.And the other had a gastroschisis and exstrophy deformity fetuse.This fetuse died in uterus and remaining fetuse had full-term live birth.(6) 35 (29.7%) pregnant women received second trimester Down's syndrome serum screening.One was high risk and was proved a trisomy 21 pregnancy.Thirty-four were low risk and had normal chromosome karyotype.Conclusion NT thickening may indicate fetal chromosome abnormalities or other structural malformations.It is a useful prenatal screening indicator.

OBJECTIVE To investigate the effect of NF-κB on cardiomyopathy induced by doxorubicin(Dox) in rats and the effect of melatonin(MT). METHODS Thirty male Sprague-Dawley rats were randomly divided into 3 groups: normal control group; Dox model group; Dox+MT group. The content of nitric oxide (NO) and the activity of inducible nitric oxide synthase (iNOS) in cardiac tissues were examined by spectrophotography method; the activity of NF-κB in myocardial cell was observed by immunohistochemistry method; the apoptosis information of myocardial cell was detected by TUNEL method. RESULTS There was significant difference in activity of NF-κB between normal control and the Dox model group. MT could inhibit the activation of NF-κB(P<0.05). There was significant difference in the content of NO and the activity of iNOS between normal control and Dox model group, MT could decrease content of NO and the activity of iNOS(P<0.05); apoptotic rate in Dox model group was significantly increased compared with that in normal control group, MT could significantly decrease myocardial cell apoptosis (P<0.05). CONCLUSION The activation of NF-κB plays an important role in cardiomyopathy induced by Dox, NF-κB seems to increase the activity of iNOS, and then significantly increase the content of NO in cardiac muscle; NF-κB possibly enhances myocardial cell apoptosis in cardiomyopathy induced by Dox. MT may inhibit the activation of NF-κB, and prevent excessive oxidative stress and suppress myocardial cell apoptosis, MT has protective effect against cardiomyopathy induced by Dox.
