BACKGROUND:Tripterygium wilfordi and its certain monomers have exact clinical effects on rheumatoid arthritis. However, there are few studies about a systematic discussion on pharmacodynamic material basis and molecular mechanism of Tripterygium wilfordi. OBJECTIVE:To explore the pharmacodynamic material basis and molecular mechanism ofTripterygium wilfordi in treating rheumatoid arthritis. METHODS: Based on the platform of Discovery Studio 4.0, the molecular set of Tripterygium wilfordiwas built and compared with the rheumatoid arthritis drug set from Therapeutic Target Database in chemical space. After that, network pharmacology was used to explore the interactions ofTripterygium wilfordi and therapeutic targets related to rheumatoid arthritis. RESULTS AND CONCLUSION:The molecular sets ofTripterygium wilfordi and drugs for treating rheumatoid arthritis had similar chemical space. The pharmacodynamic material basis ofTripterygium wilfordi had 46 compounds, such as celacinnine, epigalocatechin, euonine, triptolide. They could mediate inflammation, regulate immune response, inhibit cartilage and bone destruction, improve blood stasis-type rheumatoid arthritis by acting on 10 targets, such as tumor necrosis factor-α, JAK-1, matrix metaloproteinase-1, matrix metaloproteinase-3, matrix metaloproteinase-9. Computer simulation could intuitively trace out the multi-ingredient, multi-target and multi-pathway effects of Tripterygium wilfordi.

Objective To analyze the relationship among the general self-efficacy,self-esteem and professional identification of nursing baccalaureate students and to provide some suggestions for educational practice. Methods A total of 403 nursing baccalaureate students in traditional Chinese medicine colleges were recruited. They were investigated with general self-efficacy scale (GSES), Rosenberg self-esteem scale(SES)and questionnaire for baccalaureate nursing students (QBNS). The relationship among general self-efficacy,self-esteem and professional identification was analyzed by multiple stepwise regression analysis. Results The mean score of general self-efficacy was 23.81± 5.27. There were significant differences in the score of general self-efficacy among different grades and enrollment methods (P<0.01). The nursing students,general self-efficacy was positively correlated with self-esteem,professional identification,professional emotion and professional skills(r=0.11-0.50, P<0.05). Conclusions Nursing educator should pay attention to the cultivation of self-esteem and professional identity in the training of nursing student in order to improve the self-efficacy of nursing students.

Objective To investigate the correlation between the CD40 gene( - 1 C/T)single nucleotide polymorphism(SNP) and acute coronary syndromes(ACS), and the expression of CD40 on platelets. Method A total of 562 patients with ACS canfirmed by coronary angiography were divided into 3 groups according to the clinical characteristics, namely ACS patients( n = 210), stable angina(SA) patients( n = 189) and control group( n = 163).ACS was defined as ischemic chest pain at rest resulting in admission to hospital and > 50% stenosis in a major coronary artery with or without a rise in troponin Ⅰ. SA was defined as stable effort-related angina without change in angina pattern in 3 months. Patients with infection, tumor, or liver or kidney disease were excluded The gene polymorphism was measured by the polymerase chain reaction and restriction fragment length polymorphism(PCR-RFIP) and identiffed by sequencing. The expression of CD40 on platelets was detected by flow cytometry. The frequency, distribution of genotypes was compared using cross-tabulation and standard X~2 test. Result The CC genotype(31% ) and C allele of frequency(57.9%)of CD40 gene in ACS patients were significantly higher than those in SA(15.9%, 43.1% ) and control groups( 16.1%, 42.6% ). No significant difference of the genotypes or allele frequencies was found between SA and control group(X~2 = 0.053, P = 0.974;X~2 = 0.017, P = 0.897). 1he expression of CD40 on platelets in patients with C alleles carries was significandy higher than that of T allele carries in each group( P <0.0001). Conclusions CD40- 1C/T polymorphism was associated with ACS in Chinese Han nationallity.

Objective: To investigate the associations between smoking and literacy on health among 4-6 grade primary school students. Methods: A questionnaire survey was conducted to research on health literacy and smoking among 4-6 grade pupils in Shandong province, through a multi-stage stratified cluster random sampling method. Sociodemographic characteristics, health literacy level and smoking rate were collected from respondents. Binary logistic regression analysis was used to evaluate the association of smoking and health literacy. Results: A total of 9 240 questionnaires were distributed, with the rate of valid response as 99.7%. The current smoking rate of the students was 2.6%, on higher in boys (3.1%) than in girls (2.0%). 60.8% of 4-6 grade students were found to have adequate health literacy level. Levels of literacy health in both boy and girl school students appeared 56.7% and 64.9%, respectively. Results indicated that health literacy in smokers (14.4%) was lower than that in non-smokers (62.0%). Results from the binary logistic regression analysis showed that the independent influencing factors would include grade, father’s education level, economic situation of the family, self-assessment on the school record and literacy on health (P<0.01). After controlling the other independent variables, the smoking rate was 8.62 (1/0.116) times in students with low literacy level on health, than those with high literacy level. Conclusions Literacy on health was significantly associated with smoking in the 4-6 grade pupils of Shandong province.

Objective: To investigate whether platelet-derived growth factor-BB (PDGF-BB) can regulate phenotypic transformation of pulmonary artery smooth muscle cells (PASMCs) via SIRT3 affecting glycolytic pathway. Methods: The PASMCs were isolated from Sprague Dawley rats. PASMCs were divided into 3 groups by using 2-deoxyglucose (2-DG), an inhibitor of the glycolytic pathway: normal control group, PDGF-BB group(30 ng/ml) and PDGF-BB (30 ng/ml)+2-DG (10 mmol/L) group. In lentivirus-mediated overexpression assay, cells were divided into control group, PDGF-BB group(30 ng/ml), PDGF-BB+deacetylase sirtuin-3 (SIRT3) overexpression group and PDGF-BB+empty vector group. The expression levels of phenotype related index such as α-smooth muscle actin (α-SMA), smooth muscle myosin heavy chain (SM-MHC), calponin, vimentin were detected by qRT-PCR and Western blot. Meanwhile, the expression of α-SMA was detected by cellular immunofluorescence staining. EDU staining was used to detect the proliferation of PASMCs. The expression of SIRT3 was detected by Western blot. The expressions of glucose transporter 1 and aerobic glycolytic enzymes were detected by qRT-PCR and Western blot in lentivirus-mediated overexpression assay. Results: (1) PDGF-BB affects PASMCs phenotypic transformation through glycolytic pathway: compared with normal control group, PDGF-BB significantly decreased the expressions of contractile phenotype markers such as α-SMA, SM-MHC, calponin mRNA and protein (all P<0.05), but it increased the expressions of the synthetic phenotype marker vimentin mRNA and protein (both P<0.05). Cellular immunofluorescence assay showed that PDGF-BB significantly decreased the number of α-SMA positive cells, while 2-DG reversed the process. (2) PDGF-BB promoted cell proliferation through glycolytic pathway: the proliferation of PASMCs was significantly higher in PDGF-BB group than in control group (P<0.05), and which could be significantly reduced by 2-DG (P<0.05). (3) PDGF-BB inhibited the expression of SIRT3 protein in PASMCs: the expression of SIRT3 protein in PDGF-BB group was lower than that in control group (P<0.05). (4) PDGF-BB affected glycolytic pathway through SIRT3:compared with the control group, PDGF-BB significantly increased the expression levels of glucose transporter 1 (Glut1), hexokinase 2 (HK2) and 6-phosphfructo-2-kinase 3 (PFKFB3) mRNA (all P<0.05), which was reserved by over-expression of SIRT3. There were no significant difference in mRNA expression levels between PDGF-BB group and PDGF-BB+empty vector group (P>0.05).Compared with the control group, PDGF-BB significantly increased the expression levels of Glut1, HK2 and PFKFB3 protein(all P<0.05), which was reserved by over-expression of SIRT3. There were no significant differences in protein expression levels between PDGF-BB group and PDGF-BB+empty vector group (all P>0.05). Conclusion PDGF-BB regulates phenotypic transformation of PASMCs via SIRT3 affecting glycolytic pathway.

Objective: To investigate the feasibility and efficacy of the establishment of regional cooperative acute ST-segment elevation myocardial infarction (STEMI) rescue network among the prefectural-level city hospitals in China. Methods: Based on real-time remote electrocardiogram transmission and "120" emergency systems, we established a regional collaborative STEMI treatment network with our hospital as the network unclears including 8 second-class affiliated hospitals of Jiangsu University in 2013. STEMI treatment time, therapeutic effects and economic indexes were compared before (from January 2010 to December 2012, 180 cases, pre-network) and after (From January 2013 to December 2015, 374 cases, post-network) the establishment of the regional collaborative STEMI treatment network. Results: Post establishment of the rescue network, mean first medical contact (FMC) to balloon (FMC-to-B) time, referral time and obtaining informed consent time were all significantly decreased from (191±41), (94±18), (25±9) minutes to (93±19), (53±18), (7±5) minutes, respectively, in comparison with the pre-network era(all P<0.05). There was a trend of prolonged FMC-to-B time in proportion to aging of STEMI patients(trend P<0.05). Three months post discharge, LVEF was higher (55.3%±10.7% vs. 48.8%±12.1%, P<0.05) and LVEDd was lower ((49.1±10.8)mm vs.(51.8±9.2)mm, P<0.05) in the post-network group compared to pre-network group.In-hospital mortality was also significantly reduced post the establishment of the rescue network (2.14%(8/374) vs. 3.89%(7/180), P<0.05). The results also showed that the total costs (42 017(25 069, 75 148)yuan vs.51 030(28 137, 105 861)yuan), days of hospitalization ((9.1±4.5) days vs. (15.3±4.8)days) and percentage of medicine and consumables were all significantly decreased in the post-network group compared to pre-network group(all P<0.05). Conclusion Establishment of the regional cooperative rescue network is feasible among the prefectural-level city hospitals in China. Establishment of such network can improve the prognosis and decrease the FMC-to-B time, the rate of in-hospital mortality and financial burden of patients with STEMI, and serves as an effective strategy to improve the rescue ability for STEMI patients.
