Objective To study the correlation between prognosis of non-small cell lung cancer ( NSCLC) patient and serum levels of HGF and IL-6. Methods Eligible 109 NSCLC patients and preoperative blood samples of each patient in our hospital from March 2013 to May 2014 were collected. Then the levels of HGF and IL-6 of serum samples were detected by using ELISA kit. All patients were followed up for 1 year. The neoplasm staging:67 cases were stagingⅠ-Ⅱ,38 cases were stagingⅢ,2 cases were staging IV. There were 79 cases with ad-enomatous carcinoma( ADC) ,26 cases with squamous carcinoma( SCC) and 4 cases with NSCLC. According to the TNM staging,there were 79 cases in pN( -) group,31 in pN( +) group,77 in pT(T1-T2) group and 28 in pT(T3-T4) group. Results The average concentration of HGF and IL-6 in serum were 860 pg/mL and 2. 7 pg/mL respectively. Analysis of survival indicated that,compared to those patient with lower serum level of HGF and IL-6,the survival rate of patient with high serum level was much lower. The difference was statistically signifi-cant (HGF,P=0. 019;IL-6,P=0. 002). The analysis of the patients with stageⅢdisease separately also indicated that survival rate of pa-tient with lower serum of HGF and IL-6 was higher than others. Conclusion The serum levels of HGF and IL-6 might be a effective indica-tors for predicting prognosis of the NSCLC paitents.

Objective:To screen the differentially expressed miRNAs in umbilical cord tissue of children with nonsyndromic cleft lip and/or cleft palate( NSCL/P) using miRNA microarray and comprehensive bioinformatics analysis for the prediction of related the bio-logical process and signaling pathways. Methods:Umbilical cord tissues of 4 cases of healthy newborns' and 4 lip or palate tissues of 4 cases with NSCL/P without other disease aged younger than 2 years were collected. The differentially expressed miRNAs were screened by miRNA microarray. Targets of dysrugulated miRNAs were predicted by TARGETSCAN-VERT, MIRDB and RNA22-HSA. All the gene sets were analyzed by gene ontology and pathway enrichment. Results: MiRNA microarray demonstrated that 254 miRNAs were dysregulated(181 miRNAs were up-regulated and 73 downregulated,P <0. 05). The dysregulated miRNAs targets contained 5029 genes. The dysregulated miRNAs targets were enriched in anatomical structure development,cell adhesion,cell proliferation,cell motili-ty and other biological processes. The dysregulated miRNAs targets were enriched in Wnt, mTOR, cGMP-PKG, TGFβ, PI3K-Akt and other signaling pathways. Conclusion:The target genes set of miRNAs are enriched in multiple biological processes and signaling path-ways related to NSCL/P, which indicate that genetic and environmental factors may influence the development process of NSCL/P.

Objective To systematically analyze and evaluate the association between the peptidylarginine deiminaseⅣ(PADI4) gene and rheumatoid arthritis (RA) based on the published data,and to provide evidence for the pathogenesis of RA.Methods By selecting five SNPs in PADI4 (rs11203366,rs11203367,rs874881,rs2240340,rs1748033) which had been extensively examined.Meta-analysis on each SNP was performed step by step according to Hugenet manual to investigate the association of the polymorphisms of the PADI4 gene with RA.Results This Meta-analysis enrolled 15 659 RA patients and 22 019 healthy controls from 21 studies worldwide.It demonstrated that rs11203366,rs11203367,rs2240340 and rs 1748033 confered susceptibility to RA in Asian ethnicity (P＜0.01,0.03,＜0.01,＜0.01),while rsl1203366,rsl1203367 and rs874881 confered susceptibility to RA in Caucasian of European ancestry (P=0.0002,0.004,0.03).It also shown that no significant association between rs874881 and RA in the Asian ethnicity populations (P=0.2),or rs2240340,rs1748033 and RA in Caucasian of European ancestry (P=0.18,0.1 ).A linkage disequilibrium study was also performed.The LD study showed that rs11203366,rs11203367,rs874881,rs2240340 and rs1748033 were in linkage disequilibrium both in the Asian ethnicity and Caucasian,which was basically inconsistent with the results of Meta-analysis.The conflicting results should be explained by many aspects such as bias in sample selection,genotyping,and the stratification.Conclusion The PADI4 genotype is partially associated with RA,and the underling mechanisms need further study.Haplotype based research and Metaanalysis would be valuable.

Objective: To evaluate the safety and anticoagulant efficacy of domestic bivalirudin injection during emergent percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI).
Methods: A total of 75 STEMI patients were randomly divided into 2 groups according to anticoagulant used in emergent PCI procedure. Bivalirudin group, the patients received intravenous domestic bivalirudin, n=40 and Heparin group, n=35. The activated clotting time (ACT) was tested at pre-PCI, 5 minutes after medication, immediately after PCI, 30 minutes, 1 hour and 2 hours after medication respectively. The activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT) and ifbrinogen (FIB) level were measured at before medication and 6, 24, 72 hours after medication.
Results: All patients in Bivalirudin group had ACT>225s at 5min after medication as PCI requirement, while 1 patient in Heparin group could not reach the requirement and the extra dose was added. Both groups maintained ACT>225s during PCI procedure. Bivalirudin group had the lower ACT levels than those in Heparin group at 30 min, 1-and 2-hour after the medication, P<0.05. The post-PCI levels of APTT, PT, TT and FIB were similar between 2 groups, all P>0.05. The no-cardiac event surviving rate at 30 days after PCI in Bivalirudin group and in Heparin group were similar P>0.05 and the mild bleeding at 24 hours after PCI in Bivalirudin group was lower (0 vs 11.43)%, P<0.05.
Conclusion: Compared with heparin, domestic bivalirudin may take faster effect, with shorter half-life period for anticoagulation during emergent PCI procedure in STEMI patients.

The length of cervical canal was monitored by perineal ultrasonography in 377 pregnant women with 22 to 36 weeks of gestation,at the same time the contents of fibronectin (fFN) in cervical secretions were measured.The rate of cervical canal length shortening from the time of first visit to the appearance of preterm signs was calculated.When the cervical length shortening rate was 16％ ～ 60％,fFN (+) was correlated with higher preterm birth rate (P ＜0.01),while when the shorten rate ＞ 60％ there was no significant difference in preterm delivery rate between fFN (+) and fFN (-) groups (P ＞ 0.05).The results indicate that the monitoring of cervical canal length combined with fiberonectin measurement in cervical secretion may better predict pretenn birth.

Objective To analyze the influencing factors of self-management ability of coronary heart disease patients after percutaneous coronary intervention (PCI) and construct a nomogram model. Methods A total of 247 CHD patients who underwent PCI were selected as the research subjects, and all of them were evaluated by Coronary Heart Disease Self-management Scale (CSMS). Multivariate Logistic regression analysis was used to screen out the independent influencing factors of self-management ability of CHD patientsafter PCI, and R software was used to construct a nomogram model. The discrimination, calibration, and goodness-of-fit of the nomogram model were evaluated by receiver operating characteristic (ROC) curve, calibration curve, and Hosmer-Lemeshow goodness-of-fit test. Results The average CSMS score of 247 patients was (86.79±9.22), and these patients were divided into low-score group(89 patients) and high-score group (158 patients)based on the critical value of 86.79 points. There were significant differences in age, education level, monthly per capita family income, and self-efficacy between the low-score group and the high-score group (P < 0.05). Multivariate Logistic regression analysis showed that age, education level, monthly per capita family income, and self-efficacy were independent influencing factors of self-management ability of CHD patients after PCI (P < 0.05). The nomogram model constructed based on the four influencing factors found that age >70 years increased the weight by 86.2 points, education level below high school increased the weight by 87.4 points, monthly per capita family income < 3 500 yuan increased the weight by 82.3 points, and low self-efficacy increased the weight by 99.6 points. The results of ROC curve analysis showed that the area under the curve of the nomogram model for predicting self-management ability ofCHD patients after PCI was 0.842 (95%CI, 0.794 to 0.890). The slope of the calibration curve was close to 1, and the results of goodness-of-fit test was as follows: χ²=10.226, P=0.233. Conclusion Age, education level, monthly per capita family income, and self-efficacy are influencing factors of self-management ability of CHD patients after PCI, and the nomogram model constructed based on these factors has high predictive value for self-management ability.

Objective: To explore the relationship between bullying among middle school students and family factors in a city of central China, so as to provide support for the prevention and reduction of school bullying among middle school students. Methods: The stratified cluster random sampling method was used to investigate the bullying involvement and family factors of 2 996 middle school students from first grade in junior high school to third grade in high school in a city in central China. Chi-square test and Logistic-regression analysis were used to analyze the relationship between family factors and bullying participation of middle school students. Results: Among 2 996 students, 390 students(13.0%) were found of having bullying behavior, and 1 127 students(37.6%) were found of being bullied. Univariate analysis showed that there were statistically significant differences in family factors such as whether she or he is the only child, father-child relationship, mother-child relationship, marital status of parents, whether the mother work away from hometown, education level of father and mother(χ2=8.88, 56.49, 30.85, 30.91, 3.89, 10.36, 11.72；25.00, 69.33, 46.76, 57.09, 3.93, 23.19, 45.49, P<0.05). Logistic regression analysis showed that the only child and mother’s education degree was junior college and below were the risk factors for middle school students’ bullying involvement (OR=1.37，1.39). Parents’ harmonious marital status and father’s not working outside are the protective factors of middle school students’ bullying(OR=0.53, 0.83).The only child is the risk factor of bullying in middle school students (OR=1.42), and good father relationship is the protective factor of bullying in middle school students (OR=0.38). Conclusion Family factors have a certain impact on the involvement of middle school students in bullying in a city of central China, and corresponding preventive measures should be formulated from the perspective of family to focus on the intervention of high-risk groups.

Objective:To investigate the changes of T lymphocyte subsets and cytokines in children with he-patitis B virus(HBV)-associated glomerulonephritis (HBV-GN), and their relationship with HBV-DNA load.Methods:Forty-one children who was the first diagnosed with HBV-GN in Department of Pediatrics, the People′s Hospital of Gansu Province and Institute of Infectious Diseases, the First Hospital of Lanzhou University from September 2012 to September 2016 were collected as the objects(HBV-GN group). At the same time, the 40 patients with HBV infection (chronic HBV infection, normal liver and kidney function, normal 24-hour proteinuria quantitation, no hematuria under the microscope, no recent symptoms of cold and fever, etc.) were enrolled as the control group.The levels of T lymphocyte subset, tumor necrosis factor α(TNF-α), interferon-γ (IFN-γ), interleukin (IL)-2, IL-4, IL-6, IL-8 and IL-10 in the HBV-GN group and the control group were compared, and the relationship between HBV-DNA and cell factors was farther analyzed.Results:Compared with the control group, the proportions of CD3 + T, CD4 + T lymphocyte and CD4 + /CD8 + ratio decreased in the HBV-GN group(0.632±0.052 vs.0.692±0.047, 0.204±0.050 vs.0.466±0.038, 0.006±0.002 vs.0.017±0.003, t=1.025, 3.342, 5.234, all P<0.05), and the proportions of CD8 + T lymphocyte was significantly higher than that in the control group (0.411±0.023 vs.0.220±0.043, t=4.452, P<0.01). Besides, IL-2 and IFN-γ levels in the HBV-GN group were significantly lower than those in the control group[(23.36±2.55) ng/L vs.(36.33±1.24) ng/L, (19.20±2.18) ng/L vs.(61.25±2.08) ng/L, all P<0.05], and the serum levels of TNF-α, IL-4, IL-6, IL-8, and IL-10 were significantly higher than those in the control group[(19.60±1.46) ng/L vs.( 6.68±2.32) ng/L, (13.65±3.34) ng/L vs.(1.35±1.52) ng/L, (5.57±1.02) ng/L vs.(1.43±0.57) ng/L, (26.32±3.45) ng/L vs.(9.68±2.55) ng/L, (19.82±2.78) ng/L vs.(1.02±0.56) ng/L, all P<0.01]. Moreover, in HBV-GN patients, there was negative correlation between HBV-DNA load and IFN-γ, IL-2( r=-0.985, -0.943, all P<0.05), and positive relationship in HBV-DNA load with TNF-α, IL-4, IL-6, IL-8 and IL -10 levels( r=0.942, 0.966, 0.953, 0.944, 0.963, all P<0.05). Conclusions:There is an CD4 + /CD8 + imbalance and an abnormal level of cell factors in HBV-GN progression.In further HBV-GN treatment, HBV-DNA and the cell factors should be detected simultaneously to dynamically eva-luate the illness change and the clinical curative effect.

Objective:To study the influencing factors of nursing dependence in patients with moderate to severe dementia.Methods:Eighty-seven patients with moderate to severe dementia were enrolled in the Department of Neurology, the First Affiliated Hospital of China Medical University. The demographics of each patient were recorded. The Chinese version of the Nursing Dependence Scale (CDS) was evaluated. The simple mental state test (MMSE), severe cognitive impairment series (SIB-S), and 6-minute walk test score (6MWT) for each patient. Mobility Test Score (TUG), US Cornell Depression Table Score (CSDD), Apathy Score (AES-10)were recorded. Demographic variables, MMSE, 6MWT, TUG, CSDD,AES-10, SIB-S as an independent variable, CDS as a dependent variable, multivariate linear logistic regression was analyzed.Results:The median comorbidities were 2, 6MWT, TUG, MMSE, SIB-S, CSDD, AES-10 score was (208.54±74.02) m and (24.56±11.83), (12.67±5.47), (40.85±7.54), (7.92±4.48), (25.28±7.23) points, which were independent factors with statistically significant impact on the care dependency scale ( B value was -0.67-0.67, P < 0.05 or 0.01). Conclusions:Patients with moderate to severe dementia have more comorbidities, lower physical endurance and increased dependence on depression.

Objective:To evaluate the guidelines on discharged health education for solid organ transplant recipients at home and abroad, analyze the characteristics of each guideline, so as to provide reference for the development of health education for organ transplantation in China.Methods:This was a guideline quality evaluation study. The guidelines on health education for discharged recipients with solid organ transplantation were searched on the websites of clinical practice guidelines, the websites of transplantation professional associations, and Chinese and English databases at home and abroad through computers. The search time limit was from January 1, 2011 to January 1, 2022. The quality of guidelines that met the inclusion and exclusion criteria was evaluated using the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) .Results:A total of 8 guidelines were included. The overall quality evaluation of the guideline was Grade A ( n=2) and Grade B ( n=6) . In terms of standardized scores in six areas of quality evaluation, the average values of scope and purpose, stakeholder involvement, rigour of development, clarity and presentation, applicability as well as editorial independence were 87.62% (70.37%-100.00%) , 75.46% (44.44%-97.22%) , 66.54% (43.75%-93.06%) , 90.16% (77.78%-96.30%) , 48.18% (20.83%-68.75%) and 74.13% (8.30%-97.22%) , respectively. The recommendations of the guidelines covered 9 aspects: team composition and support services, drug management, infection prevention, complication management, diet and nutrition, daily life and social reintegration, contraception and reproduction, psychological guidance and follow-up review. Conclusions:The development of guidelines for different types of solid organ transplantation varies. The overall quality of the guidelines needs to be improved and the content needs to be refined. In the future, we can learn from foreign high-quality guidelines to carry out localization practice, so as to build a health education related guideline for discharge of solid organ transplantation that is suitable for China's national conditions as soon as possible.
