Objective: Self-enhancement is a kind of motive that urges people to attend exclusively to the positive aspects of himself,it is so intense that individuals even tend to distort the threatening information to some degree so that they can maintain a positive self-view. This research is to investigate the pattern of self-enhancement of Chinese people. Methods: Self-enhancement was measured by requiring participants to make self attribution as well as other attribution of their success and failure on eight factors. Results: There existed strong self-enhancement motive in Chinese individuals. Specifically,Chinese undergraduates attribute their success to inner factors such as personality and effort. This trends also evident in the conditions in which participants were asked to speculate the attribute pattern of other people like his/her mother on their own success and failure. Conclusion: Chinese undergraduates tend to enhance the self-image in other people's eyes.

Objective To evaluate the predictive value of Wells score combined with D-dimer in the diagnosis of acute pulmonary embolism.Methods A total of 540 patients with suspected pulmonary embolism admitted from 2008 to 2011 were enrolled for study.The diagnosis of pulmonary embolism (PE) was confirmed by using computed tomography pulmonary angiography (CTPA).These patients were divided into two groups:PE group and non-PE group.Comparative analysis was carried out in demographics,underlying diseases,chief complaints,physical signs,venous thrombosis risk factors,laboratory findings and Wells scores between the two groups.Results Of 502 patients selected into this study,there were 246 in PE group and 256 in Non-PE group.The incidence rates of history of recent surgery or bed-ridden,recent fracture of pelvis or lower limb,symptoms of hemoptysis,transient disturbance of consciousness,signs of unilateral lower limb swelling,hypoxia and hypocapnia of arterial blood gas analysis,elevated levels of D dimer,high Wells score in PE group were significantly higher than those in non-PE group (P ＜ 0.05).And there were no statistical difference in other variables found between the two groups.The areas under the ROC curve of Wells score,D-dimer and the combination of the two were 0.775 (95％ CI:0.719-0.831),0.802 (95 ％ CI:0.751-0.853) and 0.899 (95 ％ CI:0.834-0.964),respectively.And the area under the ROC curve of the combination of the two was greater than that of separated application (P ＜ 0.05).When the cut-off value of Wells score was 5 and D-dimer was 1 724 μg/L,the weighted maximum sensitivity and specificity were reached,and these cut-off values were higher than above determined values,the reliability of the diagnosis of PE was obviously increased,and those were lower than these cut-off values,the reliability of excluding PE was also increased.Conclusions Wells score combined with D-dimer showed a higher value in predicting acute pulmonary embolismthan than their separated application.

Objective To investigate the recent curative effect and adverse reactions of radiotherapy combined with temozolomide in non-small cell lung cancer (NSCLC) patients with brain metastases.MethodsThe clinical date of 51 NSCLC patients with brain metastases were retrospective analyzed in Department of Radiation Oncology of Affiliated Hospital of Hebei University.Patients were divided into experimental group (n=26) and control group (n=25) according to the different treatment methods.The experimental group underwent whole brain and local tumor radiotherapy plus temozolomide.The control group only received whole brain and local tumor radiotherapy.The recent curative effect and adverse reactions of the two groups were analyzed.Results The Karnofsky performance status score of patients in the experimental group was obviously improved than that in the control group (76.2±6.4 vs.72.8±5.3), with a significant difference (t=2.06, P=0.04).The total effective rate in the experimental group was higher than that in the control group (80.8% vs.64.0%), but there was no statistically significant difference (χ2=1.80, P=0.18).Compared with the control group, the incidences of nausea and vomiting (80.8% vs.28.0%) and bone marrow suppression (84.6% vs.24.0%) in the experimental group were significantly higher, with significant differences (χ2=14.33, P=0.00;χ2=18.91, P=0.00).There were similar incidences of headache (69.2% vs.60.1%), liver and kidney damage (73.1% vs.64.0%) in the two groups, with no significant differences (χ2=0.47, P=0.49;χ2=0.47, P=0.49).Conclusion Radiotherapy combined with temozolomide can improve the quality of life in NSCLC patients with brain metastases, which has controllable and tolerable adverse reactions.

Objective Analyze the causes of ambiguous medical records to provide evidence for the DRGs.Methods 268 Ambiguous medical records were selected from 17 751 surgery medical records between 2010 and 2014 based on major diagnosis and major surgery.The single factor Chi-square test was used to study the influence of various inpatient characteristics on the occurrence of ambiguous medical records, and those significant variables were given assignment to find influencing factors of ambiguous medical records by using logistic regression analysis.Results Ambiguous medical records account for 1.51％ of all surgical medical records.Logistic regression analysis results show that such risk factors as discharging from internal medicine, death of patient, transfer between departments, elderly, long time of hospitalization, and tumor patients, as contributing to ambiguous medical records.All the results are statistically significant (P＜0.05), including discharging from which departments (OR=6.595, 95％CI..5.043 ～ 8.625), death of patient (OR=3.787, 95％ CI: 2.611 ～ 5.492) and transfer between departments (OR =2.746, 95％ CI: 2.061 ～ 3.659), which rank important risk factors for ambiguous medical records.Conclusion Analysis of the causes of ambiguous medical records provides important evidences for the hospital to improve its medical record quality management.

Aconitum, as a kind of common traditional Chinese medicine, contains multiple biological active substances, with a very high medicinal value but high toxicity. Its major toxic ingredients are aconitine, mesaconitine and hypaconitine, which are also efficient ingredients. Therefore, the safety of its clinical application has aroused wide attention. With the constant deepening of drug development studies, people want to learn about its toxic mechanism and the regularity of its emergence and development of its toxicology, so as to make a scientific and rational assessment for its safety. Therefore, toxicokinetics and metabonomics have gradually become important content in the new drug assessment. During the development of drug performance, it is crucial to establish a scientific, objective and standardized Aconitum safety evaluation system and correctly assess and utilize its toxicity. Having summarized studies on metabonomics and toxicokinetics of Aconitum drugs in recent years, authors proposed to strengthen the studies on Aconitum drug safety assessment and establish a scientific and standardized safety evaluation system as soon as possible, in order to make the national treasure more useful.

OBJECTIVE: To elucidate the correlation between CKLF-like marvel transmembrane domain containing member (CMTM5) gene and the risk of in-stent restenosis (ISR) with coronary artery disease (CAD) patients and to detect the effects and mechanisms of CMTM5-stimulated genes on human vascular endothelial cells (ECs) proliferation and migration. METHODS: A total of 124 hospitalized patients in Shijitan Hospital were enrolled in this study. All the CAD patients were detected with platelet reactivity and grouped into two groups according to platelet reactivity; ISR was conformed by coronary angiography; RT-PCR method was used to detect CMTM5 gene expression; The CMTM5 over expression, reduction and control EC lines were established; Cell count, MTT, Brdu and flow cytometry methods were used to detect the proliferation of ECs, scratch and transwell experiments to test the migration of ECs, Western blot was used to detect signal path expressions. RESULTS: CMTM5 gene expression in HAPR (High on aspirin platelet reactivity) group was 1.72 times compared with No-HAPR group, which was significantly higher than No-HAPR group. HAPR group ISR rate was 25.8% (8 cases), the incidence of No-HAPR ISR group was 9.7% (9 cases), and the results showed that in HAPR group, the incidence of ISR was significantly higher than that in No-HAPR group (P=0.04, OR=0.04, 95%CI=1.16－7.52), which showed that CMTM5 gene was significantly correlated with the risk of ISR. In HAPR group ISR rate was 25.8% (8 cases), the incidence of ISR in No-HAPR group was 9.7% (9 cases), and the results showed that the risk of ISR in HAPR group was significantly higher than that in No-HAPR group. All the results showed that CMTM5 was significantly correlated with the risk of ISR in CAD patients (P < 0.05). CMTM5 overexpression inhibited the proliferation and migration ability of ECs (P < 0.05), PI3K/Akt signaling pathways were involved in the role of regulation on ECs. CONCLUSION Our results revealed that CMTM5 gene was closely related with ISR, CMTM5 overexpression may repress ECs proliferation and migration through regulating PI3K-Akt signaling.

OBJECTIVE: To elucidate the correlation between CKLF-like MARVEL transmembrane domain containing member 5 (CMTM5) gene and the risk of coronary artery disease (CAD), and to detect the effects of CMTM5 gene expression changes on the ability of adhesion and migration of THP-1 cells. METHODS: Using case-control method, a total of 700 hospitalized patients in Shijitan Hospital were enrolled in this study. CAD were diagnosed by coronary angiography, which was defined as at least one blood vessel diameter stenosis ≥50% according to the result of coronary angiography. Reverse transcription-polymerase chain reaction (RT-PCR) method was used to detect CMTM5 gene expression; enzyme linked immunosorbent assay (ELISA) method to detect the plasma level of CMTM5; and Logistic regression to analyze CMTM5 genes and the risk of CAD. Human vascular endothelial cells (ECs) and THP-1 cells were cultivated, adhesion and Transwells experiments were used to evaluate the chemotactic capabi-lity of CMTM5 gene on THP-1 cells. RESULTS: In this study, 350 CAD patients matched with 350 control patients were included. RT-PCR results revealed CMTM5 mRNA expression in CAD group was 3.45 times compared with control group, which was significantly higher than that in control group (P < 0.05). The levels of CMTM5 plasma protein in CAD group was (206.1±26.9) μg/L, which was significantly higher than that in control group (125.3±15.2) μg/L (P < 0.05). After adjusted for the risk factors of age, gender, BMI, smoking, hypertension, diabetes and hyperlipidemia, Logistic regression analysis results indicated that CMTM5 was the susceptibility factors of CAD, which still had significant correlation with CAD (P < 0.05). Adhesion and Transwells experiments results revealed that the numbers of adhesion and migration of THP-1 cells in CMTM5 overexpression ECs group (EO group) were significantly higher than that in lenti-mock infected ECs group (EO-MOCK group), non-infected ECs group (EN group), lenti-mock infected ECs group (ES-MOCK group), and CMTM5 suppression ECs group (ES group). On the contrary, the numbers of adhesion and migration of THP-1 cells in ES group were significantly lower than that in the other four groups (P < 0.01). CONCLUSION CMTM5 gene was closely related to the development of CAD. CMTM5 overexpression promoted the adhesion and migration of THP-1, which might play a part in the mechanisms of atherosclerosis and CAD.

Objective To report the results of a single-center, retrospective study on the effect of calcineurin inhibitors (CNI) withdraw for controlling infections and conversion to sirolimus (SRL)for ameliorating renal dysfunction. Methods A total of 947 liver transplant cases from 2002 to 2010were divided into two eras (Jan. 2002 to Dec. 2007 and Jan. 2008 to Dec. 2010). There were 234cases of infections after liver transplantation (LT) in the first era and 101 cases in the second era. And of 329 cases of CNI-related renal dysfunction after LT in two eras, 40 cases (converting group) had converted CNI to SRL, while 289 cases (reducing group) adopted protocol of CNI reducing and mycophenolate mofetil (MMF) raising. Results CNI-based IS took up 95.8 %, 95. 3 %, 97. 5 % of the IS protocols with recipient survival time longer than 1, 3, and 5 years. The primary cause for CNI withdraw was infection (88. 2 %, 15/17) in the second era, and renal dysfunction for conversion to SRL in the two eras (83. 3 %, 40/48). In the second era, 14. 9% (15/101) of the cases of infections after LT experienced CNI withdraw. Of the 15 patients, 11 had effectively controlled the infection (77. 3 %) while rejection rate was 6. 7 % (1/15). The cumulative survival rate of the second era was significantly higher than the first era (P＜0. 05). The glomerular filtration rate (GFR) of converting group at 6th week and 6th month was statistically elevated as compared with that before conversion,respectively (1.28 ± 0. 31, 1.36 ± 0. 32 mL/s vs. 0. 82 ± 0. 24 mL/s, P＜0. 05). Six months after CNI adjustments, survival rate of converting group and reducing group was 85. 0% and 83. 7 %,respectively (P＞0. 05). Conclusion Reducing or even short-term withdraw of CNI may allow the better control of infections after LT, and the conversion from CNI to SRL can ameliorate the CNIrelated nephrotoxicity. These individually tailored IS protocols will benefit the long term survival for LT.

Objective To investigate epidemiologic features of genital Chlamydia trachomatis (Ct) infection in China,and to provide scientific evidence for developing control strategies.Methods A descriptive epidemiological study was conducted to analyze personal,spacial and temporal distribution of genital Ct infection cases reported from 105 national sexually transmitted disease (STD) surveillance sites in China between 2008 and 2015.Results The reported incidence rate of genital Ct infection increased from 32.48 per 100 000 in 2008 to 37.18 per 100 000 in 2015,with the average annual rate of increase being 1.95％.There was marked variation in the reported incidence of genital Ct infection (range,＜ 1/100 000-615.99/100 000) among different STD surveillance sites,which was relatively high in the Pearl River Delta region,Yangtze River Delta region,Minjiang River region and some ethnic minority areas in western China,but low in north China and central China.In addition,no cases were reported at a few sites in rural areas.The reported annual incidence rate was higher in females than in males from 2008 to 2015,and the ratio of male to female cases decreased from 0.61:1 in 2008 to 0.46:1 in 2015.Among all age groups,the sexually active population aged 20-44 years showed high reported incidence of genital Ct infection,with the highest reported incidence observed in the group aged 25-29 years (range,116.72/100 000-142.98/100 000);the group aged 15-19 years showed the highest average annual rate of increase (10.06％) in the reported incidence of genital Ct infection.Among all kinds of medical institutions,general hospitals had the largest number of reported cases (range,66.00％-74.22％),followed by gynecology hospitals,Maternal and Child Health (MCH) hospitals and specialized dermatovenereology hospitals.Conclusions Genital Ct infection has been one of important public health issues in China,more attention should be paid to its prevention,and effective preventive measures are needed to be developed according to epidemiologic features.
