Background and Objective Large randomized controlled trials have demonstrated that percutaneous coronary intervention (PCI) with the routine use ofdrug-eluting stents is safe and effective, however, the patients older than 75 years undergoing PCI are at increased risk for major adverse cardiac events, so that the patients are usually excluded from this trial. The aim of the present study was to assess the early clinical outcome and risk factors in old patients with acute ST elevation myocardial infarction (STEMI) following primary PCI. Methods We analyzed the outcome after stenting in 136 patients older than 60 years in our coronary care unit with acute STEMI, and the patients were further classified in 2 age groups: patients≥75 years and <75 years. Results Though the older group had a higher prevalence of adverse baseline characteristics and lower final TIMI flow than those of the younger, the procedural success had no difference between two groups. The main adverse clinical events (MACE) for the old group was a little higher comparing with the younger in 12-month following up. Conclusions Our study suggest that drug-eluting stent implantation in elderly patients with acute ST elevation myocardial infarction has high initial procedural success rates despite having more severe baseline risk characteristics, and to shorten the time form symptom onset to PC1 and improve final TIMI flow strategy may decrease MACE among old patients following PCI.

BACKGROUND:Numerous studies have shown that mesenchymal stem cel s (MSCs) can effectively attenuate the fibrosis of damaged heart, lung and kidney by secreting various bioactive factors. OBJECTIVE:To evaluate the anti-fibrotic therapeutic potential of bone marrow MSCs conditioned media in vitro. METHODS:Normal fibroblasts and hypertrophic scar fibroblasts were treated with bone marrow MSCs conditioned media, then transforming growth factor-βand col agen production were analyzed by ELISA, and mRNA expression level of Smad7 and hydroxyproline content were detected by RT-PCR and colorimetry, respectively. RESULTS AND CONCLUSION:Bone marrow MSCs conditioned media significantly inhibited the production of both transforming growth factor-βand col agen in hypertrophic scar fibroblasts (P<0. 01), and up-regulated the mRNA expression level of Smad7 (P<0. 01), a major inhibitory regulator in the SMAD family. However, the normal fibroblasts were scarcely influenced by bone marrow MSCs conditioned media. These findings indicate that bone marrow MSCs conditioned media is considered a promising candidate for the treatment of hypertrophic scars, which may provide new theoretical supports to reduce cutaneous scarring.

OBJECTIVETo study the expression level of B7-H1 protein in the eyeball tissues of mice receiving corneal allograft transplantation and explore the role of B7-H1 protein in corneal immune privilege.
METHODSMouse models of corneal allograft transplantation were established, and the corneal opacity and angiogenesis index was evaluated according to the Sonoda method. Eight weeks later, the mice were examined for the occurrence of graft rejection, and the expression level of B7-H1 protein in the eyeball tissues were detected by immunohistochemistry, using 8 normal mice as the control group.
RESULTSB7-H1 protein was expressed highly in the corneal and the choroidal/ciliary body in the normal control mice and the survived mice, but was absent in mice with graft rejection.
CONCLUSIONB7-H1 protein may play a role in the immune privilege following corneal allograft transplantation in mice.

Objective This study evaluated the effects of health education promoting therapeutic lifestyle changes in a population with dyslipidemia. Methods Patients with dyslipidemia were randomly assigned to one of four groups: the current group (CG) received conventional health guidance, the educational course (EC) group attended six lectures as part of an educational course, the phone call (PC) group received twice-monthly follow-up by telephone,and the comprehensive group(EC+PC)attended both the educational course and received follow-up telephone calls. Total cholesterol (TC), total triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein (HDL-C), and the knowledge, attitude, and behavior (KAP) score for blood lipids were compared within each group and among groups. Results A total of 214 patients were enrolled and completed the study: 62 patients in CG,49 patients in EC,56 patients in PC,and 47 patients in EC+PC.There were significant differences in the EC,PC,and EC+PC groups after the 24-week intervention. For example, pre- and post-intervention values for each group were as follows:EC group:(5.74±0.69)mmol/L and(5.14±0.87)mmol/L for TC,35.22±1.67 and 42.96±5.72 for KAP;PC group:(5.63±0.58)mmol/L and(5.22±1.07)mmol/L for TC, 34.54.±0.97and 39.41±5.03 for KAP;EC+PC group:(5.60±0.48)mmol/L and(4.00±0.79)mmol/L for TC,35.44±1.80 and 45.05±3.19 for KAP, respectively (P<0.05). The CG group showed no significant differences before and after treatment:(5.66±0.54)vs.(5.32±1.28)mmol/L for TC,34.37±0.65 vs.35.28±4.02 for KAP(P>0.05).In a comparison among the four groups,the EC and PC groups showed greater improvements than the CG group.Moreover, the EC+PC group showed statistically significant differences in the results compared with the other three groups (P< 0.05). Conclusion An educational course combined with telephone follow-up calls was more effective than a single intervention in improving blood lipids and enhancing the health awareness of patients with dyslipidemia.This combined health education model not only improves the effectiveness of treatment to some degree,but also plays a role in its supervision and management.Furthermore,it may also assist in the implementation of continuous nursing services in medical institutions.

Purpose:
The aim of the study was to evaluate the status of psychological resilience among women in their second pregnancy and to investigate the possible influencing factors.
Methods:
A total of 275 women in their second pregnancy and who met the criteria were surveyed from two public hospitals in China from July 2018 to January 2019. The instruments included the General Self-designed Questionnaire, Connor–Davidson Resilience Scale, Social Support Rate Scale, and 36-item Pregnancy Stress Rating Scale.
Results:
The total psychological resilience score of second-pregnancy women was relatively low. Multivariate regression analysis identified five factors associated with psychological resilience: intimacy with husbands, social support utilization, gender of the first child, high-risk pregnancy of the first child, and the stress caused by worrying about the health and safety of the mother and fetus.
Conclusion
Women in their second pregnancy represent a unique population, and their low psychological resilience score deserves attention. Identification of factors contributing to decreased psychological resilience may enable us to design prevention and intervention strategies and to deliver specific psychological supports to pregnant women at high risk of developing negative psychology.

To develop a specific, rapid, and convenient immunochromatography assay (ICA) to detect the rabies antibody in clinical sample from immuned dogs by rabies vaccine. Colloidal gold particles labeled with purified rabies virus (CVS11) were used as the detector reagent. The staphylococcal protein A (SPA) and pured rabbit anti-rabies virus IgG were blotted on the test and control regions of nitrocellulose membrane. Then the strip was assembled with sample pad, absorbing pad, and dorsal shield. The assay samples (261 dog's serum) were collected from Wildlife Rabies Disease Diagnostic Laboratories of Ministry of Agriculture in China, Institute of Military Veterinary, Academy of Military Medical Sciences and other six provinces, including rabies virus positive and negative serum. The performance of the strip was compared to fluorescent antibody virus neutralization test. The neutralizing antibody titer could be detected above 0.5 IU. The strip did not change of performance when stored at room temperature for 12 months. It may offer reference of neutralizing antibody titer level after dogs immuned rabies vaccine and determin whether the dogs need to be immuned again.

Objective:To explore the application effect of situation comedy teaching combined with peer teaching in clinical practice teaching of undergraduate nursing students.Methods:A total of 96 undergraduate nursing students who practiced in a first-class hospital at grade 3 in 2019 were randomly divided into the observation group and the control group, with 48 nursing students in each group. The control group adopted clinical teaching mode, including group theory teaching and group operation demonstration. On the basis of this, the observation group additionally adopted the clinical teaching mode of situation comedy teaching combined with peer teaching. The differences between the two groups in the assessment of nursing knowledge and skills assessment, independent learning ability and teaching satisfaction were observed. SPSS 20.0 software was used for t-test. Results:After the implementation of clinical teaching, the scores of nursing comprehensive ability of nursing students in the observation group (87.71 ± 5.11) were higher than those in the control group (78.47±6.24) ( P < 0.05). The independent learning ability of nursing students in the observation group (98.80±10.61) was significantly higher than that in the control group (74.47±9.83), and the difference was statistically significant ( P < 0.05). The score of teaching satisfaction in the observation group (2.83±7.07) was significantly higher than that in the control group (50.17±6.75), and the difference was statistically significant ( P < 0.05). Conclusion:The application of situation domedy teaching combined with peer teaching in the clinical teaching of undergraduate nursing students can improve their independent learning ability and clinical practice ability. Meanwhile, the process of teachers and students participating in situational experience and peer analysis and discussion can increase the teacher-student interaction, and improve the satisfaction of nursing students with clinical teaching.
