Objective: To screen the best transdermal enhancers of naringenin in Premna fulva extract. Methods: Using abdominal skin of rats as experimental barrier, the in vitro percutaneous absorption experiment was established by modified Franz diffusion cell method. The cumulative infiltration and permeation rate of naringenin in three different penetration enhancers were determined by HPLC. Results: The borneol, menthol, and azone could enhance transdermal absorption of naringenin in different degree. Several penetration enhancers were increased in the following order: borneol > menthol > azone. The average percutaneous rate of naringenin was 0.136 8 mg/(cm2∙h), using 5% borneol as penetration enhancer. Conclusion: The 5% borneol is an effective transdermal enhancer for naringenin in P. fulva extract.

Objective: To explore the safety and efficacy of intravenous thrombolysis therapy with tissue plasminogen activator ( tPA) in aged acute ischemic stroke patients. Methods:The patients treated with intravenous tPA were analyzed and divided into≥80-year group (n=16) and <80-year group (n=79), and 30 hospitalized patients with the age above 80 years without thrombolytic therapy were selected as the control group. The prognosis of the three groups was compared. Results:①The incidence of ICH in the two thrombolysis therapy groups was 13. 9% and 18. 7% in 24h, and that of SICH was 5. 1% and 6. 3% with no significant difference (P>0. 05). ② No significant difference was found in favorable prognosis between the two therapy groups 90 days after thrombolysis (P=0. 771), while very bad prognosis rate was higher in the≥80-year group than in the <80-year group (P<0. 05). ③The≥80 years group had an increased favorable outcome compared with the control group (P<0. 05), while the very bad prognosis rate in the two groups showed no significant difference (P>0. 05). Conclusion:It is safe and effective for old patients to receive IV-tPA throm-bolysis therapy.

Objective To investigate the impact of applying patient-centered care concept on easing the negative moods among the parents of the neonates hospitalized in NICU.Methods The parents of neonates (76 people) hospitalized in NICU from March to May in 2012 were selected as the control group,they conducted normal nursing.The parents of neonates hospitalized in NICU during June and August in 2012 were named as the observation group (81 people).In addition to the normal nursing,they were given nursing intervention according to patient-centered care concept.The anxiety and depression moods of the two groups was analyzed.Results Before the patient-centered care concept intervention,there was no statistical difference of SAS,SDS scores for both groups.For the observation group,the SAS,SDS scores after intervention were significantly lower than those before the intervention.While for the control group,there was no statistical difference of SAS,SDS scores.After intervention,the SAS、SDS scores of the observation group were significantly lower than those of the control group,and the difference was statistically significant.Conclusions The negative moods of the parents of hospitalized neonates can be eased significantly by applying patient-centered care concept intervention.

This paper will address the development of disaster psychology and its important contribution regarding its theoretical and practical frameworks as it applies to the psychological counseling for survivors suffering from the consequences of natural disasters.This paper will also analyze how the approach of disaster psychology can be applied to work with survivors suffering from natural disasters and to alleviate psychological challenges and its influential factors which affect these individuals.Several strategies have been discussed and proposed.In addition,relevant theoretical and integrated approaches for psychological intervention support and guidance,and rehabilitation have been established.

Children are in the stage of mental and behavior development and easily sufferd from physical and psychological barriers after disaster.This paper uses the theories and methods of the developmental psychology,disaster psychology and rehabilitation psychology to analyze the psychological and behavior barriers of the disaster survivors and to discuss the psychological intervention and rehabilitation approaches.

Objective To investigate the effect of plasma erythropoietin ( EPO) concentration on left ventricular systolic function and its relationship with acute mountain sickness ( AMS ) .Methods A total of 289 healthy young men were recruited in this study and divided into five groups:plain control group (Ⅰ) with 55 subjects;acute high altitude exposure group(Ⅱ) with 74 subjects(3700 m exposure for 24 h); the group of acute exposure after acclimatization (Ⅲ) with 68 subjects(4400 m exposure for 24 h after 1 week acclimatization at 3700 m); high altitude migrate group (Ⅳ) with 19 subjects ( migration to 3700 m for more than 1 year ); and the group of exposure after migration (Ⅴ) with 73 subjects (4400 m exposure for 50 d after more than one year migration to 3700 m).Lake Louise Self-assessment Scoring System ( LLSS) was used to assess AMS .Plasma concentrations of EPO and echocardiography were also determined .Results EPO was significantly increased after acute high altitude exposure .There was no significant difference in EPO between groupⅡand Ⅲ(P>0.05), but significantly higher than in group Ⅰ (P<0.05).No significant difference was found between group Ⅳ,Ⅴ and Ⅰ (P>0.05).In group Ⅱ, positive correlation was found between EPO concentration and stroke volume (SV) as well as left ventricular diastolic diameter (LVDD) (R=0.278 and 0.236,respectively,P<0.05), while negative correlation was expressed between EPO concentration and the AMS score (R=-0.249,P<0.05).In other groups,there was no relationship between EPO concentration and the index of left ventricular function .Conclusion EPO may work on AMS through left ventricular systolic function enhancement after acute high altitude exposure .

Objective To determine whether field triage would reduce median contact-to-device ( C2D ) time in patients with ST-segment elevation acute myocardial infarction ( STEMI ) . Methods Consecutive patients with STEMI underwent primary percutaneous coronary intervention( PCI) from March 2010 to February 2014 in Shanghai Pudong Gongli Hospital were analyzed. Patients were divided into two groups. A total of 121 patients were admitted by field triage and 101 patients by non-field triage. The primary study point was C2D time and the study points secondary included ( door-to-balloor, D2B) time, peak Troponin I ( TnI) levels, hospital mortality and 30 days follow-up mortality. Results Baseline and procedural characteristics between the two groups were comparable. Comparing to non-field triage group, the C2D time was reduced [(92. 0 ± 56. 0)min vs. (131. 0 ± 61. 0)min,P﹤0. 01]. The D2B time was lower in the field triage group vs. the non-field triage group [(55. 0 ±26. 0)min vs. (96. 0 ±31. 0)min,P﹤0. 01]. The percentage of patients with C2D time less than 90 minutes increased significantly from 85. 1% to 98. 3%( P﹤0. 01 ) in the field triage group. Peak TnI level was significantly reduced in the field triage group [(23. 5 ±22. 0) μg/L vs. (43. 5 ± 39. 0) μg/L,P﹤0. 01]. In-hospital mortality and 30 days follow-up mortality did not significantly differ between the 2 groups (3. 3% and 3. 0%, P=0. 885;3. 3% and 5. 0%, P=0. 544, respectively). Conclusions In STEMI patients, field triage was associated with significantly reduced C2D and D2B times.

Objective To compare the efficacy and safety of two kinds of homemade sirolimus-eluting stents (Firebird and Excel) for treatment of acute ST segment elevation myocardial infarction (STEMI) in patients who underwent percutaneous coronary intervention (PCI). Methods The 249 consecutive patients with STEMI who underwent PCI were randomly divided into two groups: Excel group (n=136) and Firebird group (n=113). They were followed up for 6-24 months, and coronary angiography was reviewed average 12 months later. The primary endpoints were major adverse cardiac events, including death, reinfarction and target vessel revascularization. The second endpoints included late luminal loss and restenosis 12 months after treatment. Results There were no significant differences in baseline data, coronary arterial lesion before operation, and immediateness condition after PCI between the two groups (all P＞0.05). Within follow-up, there were 2 (1.47%) death cases and 1 (0.88%) death case, 1 (0.74%) and 1 (0.88%) nonfatal myocardial infarction case, 2 (1.47%) and 2 (1.77%) target vessel revascularization cases in the two groups respectively (all P＞0.05). There were no significant differences in late luminal loss of in-stent and in-segment, the rates of in-stent restenosis, in-segment restenosis and stent thrombosis, the in-stent minimal lumen diameter and in-segment minimal lumen diameter between the two groups (all P＞0.05). Conclusions The two kinds of homemade sirolimus-eluting stents may have similar efficacy and safety in patients with STEMI treated with primary PCI.
