Objective To evaluate the effect of the collaboration care model on posttraumatic growth and resilience in patients with breast cancer.Methods 70 patients who were diagnosed with breast cancer in department of Breast Surgery of the First Affiliated Hospital of Dalian Medical University were assigned into two groups by random number table.32 patients who completed the research in the experimental group received collaboration care while 31 patients who completed the research in the control group received routine care both for there months.The patients were investigated with the Posttraumatic Growth Inventory (PTGI) and Connor-Davidson Resilience Scale (CD-RISC) before and after intervention.Results After the intervention,there were significant differences in scores of posttraumatic growth [(63.83±11.87) scores vs.(60.33±10.09) scores,t=2.384] and resilience [(66.52±15.23) scores vs.(61.33±10.09) scores,t=2.472] between the two groups (P<0.05).And also there were significant differences of posttraumatic growth scores before and after intervention in the experimental group [(56.24±10.01) scores vs.(63.83±11.87) scores,t=-3.988,P< 0.01] and the control group [(56.68±10.32) scores vs.(60.33±10.09) scores,t=-2.426,P<0.05].Differences of resilience also existed in the experimental group [(61.28±14.40) scores vs.(66.52±15.25) scores,t=-3.225,P<0.01] and the control group [(63.97±17.66) scores vs.(61.33±10.09) scores,t=-2.370,P<0.05].Conclusions Collaboration care model can significantly improve the level of patients' posttraumatic growth and resilience.
2.Research progress of the drug-coated stents.
Journal of Biomedical Engineering 2005;22(2):389-391
Emplacing a stent in the coronary artery has many characteristics. The installation is easy to do and the stent has evident curative effect. However, it will cause thrombosis and immunoreaction because it is metal. So suburgent thrombosis and restenosis after surgeries are still two major complications. The drug-coated stent is one kind of the drug-eluting stents, whose metal surface is coated by some polymer that combines with a sort of effective drug or antibody. It can transport the drug or antibody to the localily of pathological changes and there in it improves the local drug concentration. In this paper the research progress of interrelated issues about the drug-coated stent is reviewed.

It is well known that beta-elemene is a broadly effective antitumor drug. In recent years, many studies suggested that beta-elemene also has potential value in the treatment of atherosclerosis and restenosis. In this paper, the effect of beta-elemene in inhibition of angiogenesis, inhibition of thrombus formation, improvement of hemorheology, protection against oxidative injuries, anti-inflammation and suppression of restenosis after percutaneous transluminal coronary angioplasty (PTCA) are summarized and reviewed.

Objective To investigate the epidemiological characteristics of device-associated infection (DAI)in neonatal intensive care units(NICUs)of tertiary first-class hospitals in China,and provide scientific evidence for the prevention and control of neonatal DAI.Methods Neonates in NICUs at 17 hospitals of 9 provinces from October 2013 to September 2014 were selected for multicenter study,DAI was surveyed prospectively according to the uni-form diagnostic criteria and methods.Results A total of 12 998 neonates were monitored,the total patient-days were 126 125 d,13 cases of central line-associated bloodstream infection (CLABSI)and 70 cases of ventilator-asso-ciated pneumonia (VAP)occurred,central line utilization rate was 15.56%,incidence of CLABSI was 0.66/1 000 device-days;ventilator utilization rate was 7.67%,incidence of VAP was 7.23/1 000 device-days.Utilization rates of central line and respirator in neonates with body weight ≤ 1 000 g was the highest,which were 61 .06% and 29.91 % respectively;In NICUs with 20-30 beds,utilization rate of central line was the highest(16.67%),and res-pirator was the lowest(4.11 %);of hospitals in different regions,central line and respirator utilization rate in south-west China was the highest.Of different sizes of ICUs,VAP per 1 000 device-days was the lowest in NICUs with 20-30 beds(2.36 ‰).Difference in incidence of CLABSI and VAP per 1 000 device-days in neonates at NICUs of different regions were significantly different;incidence of CLABSI and VAP per 1 000 device-days was highest in southern China(2.68 ‰ and 31 .06‰ respectively),followed by southwest region.Of different quarters,incidence of CLABSI,and VAP per 1 000 device-days were not significantly different(all P >0.05).Conclusion Device utili-zation rate and incidence of DAI in China are both high,and are different in neonates of different birth weight,at different sizes of NICUs,as well as different regions,monitoring should be intensified,prevention and control measures should be implemented according to infection characteristics.

Polymer nanoparticles generally refer to hydrophobic polymers-based nanoparticles, which have been extensively studied in the nanomedicine field due to their good biocompatibility, efficient long-circulation characteristics, and superior metabolic discharge patterns over other nanoparticles. Existing studies have proved that polymer nanoparticles possess unique advantages in the diagnosis and treatment of cardiovascular diseases, and have been transformed from basic researches to clinical applications, especially in the diagnosis and treatment of atherosclerosis (AS). However, the inflammatory reaction induced by polymer nanoparticles would induce the formation of foam cells and autophagy of macrophages. In addition, the variations in the mechanical microenvironment of cardiovascular diseases may cause the enrichment of polymer nanoparticles. These could possibly promote the occurrence and development of AS. Herein, this review summarized the recent application of polymer nanoparticles in the diagnosis and treatment of AS, as well as the relationship between polymer nanoparticles and AS and the associated mechanism, with the aim to facilitate the development of novel nanodrugs for the treatment of AS.

Coronary atherosclerotic heart disease is a serious threat to human life and health. In recent years, the main treatment for it is to implant the intravascular stent into the lesion to support blood vessels and reconstruct blood supply. However, a large number of experimental results showed that mechanical injury and anti-proliferative drugs caused great damage after stent implantation, and increased in-stent restenosis and late thrombosis risk. Thus, maintaining the integrity and normal function of the endothelium can significantly reduce the rate of thrombosis and restenosis. Stem cell mobilization, homing, differentiation and proliferation are the main mechanisms of endothelial repair after vascular stent implantation. Vascular factor and mechanical microenvironmental changes in implanted sites have a certain effect on re-endothelialization. In this paper, the process of injury caused by stent implantation, the repair mechanism after injury and its influencing factors are expounded in detail. And repairing strategies are analyzed and summarized. This review provides a reference for overcoming the in-stent restenosis, endothelialization delay and late thrombosis during the interventional treatment, as well as for designing drug-eluting and biodegradation stents.
