Objective To assess the diagnostic value of DR,SCT,MSCT and MRI in diagnosis of osteoid osteoma.Methods Nineteen cases of osteoid ostcoma proved by surgical pathology were collected,Among the 19 cases,all patients had DR and CT scanning,8 with MR imaging.All the DR image processing were performed to display the nidus.Ten patients were examined by SCT axial scanning and 9 cases were performed by MSCT using isotropic parameters,then multi-direction MPR were performed.The ability of DR,SCT,MSCT and MKI in demonstrating the nidus and the surrounding reaction were analyzed.Results Among 19 cases.only 6 cases showed nidus on DR before image processing and 12 showed nldus after image processing.All cases with CT scanning showed nidus.Among 8 cases with MRI.only 6 eases could be diagnosed correedy.The nldns could be ariarmed in only 4 cases.and the nidus was affirmed by comparing with DR or CT in 2 eases,the other 2 cases were misdiagnosis.Among 10 eases with SCT,only 6 cases showed calcification of nidus.Whereas among 9 cases with MSCT,8 cases showed calcification of nidus.There were also soft tissue and bone marrow edema around the nidus on MR imaging in all 8 cases.Conclusion Nidm is the key in diagnosing the osteoid osteoma correctly.DR is a basic checking method for osteoid osteoma.DR image processing con improve the display rates of nidus.CT scan is the best method to demonstrate the nidus.MSCT is better than SCT in demonstrating the nidus and the surrounding reaction.MRI can demonstrate the soft tissue and bone marrow edema around the nidus sensitively.but probably lead to an incorrect diagnosis.Combining with DR or CT.MRI can make an accurate diagnosis.

Objective To study preoperative nursing intervention mode for thyroid surgery and its effect.Methods 78 patients were randomly divided into two groups.39 patients in the intervention group received psychological care 30 minutes before operation besides preoperative interview 24 hours before operation,while 39 patients in the control group received routine visit 24 hours before operation.Indexes including the values of blood pressure,heart rate and the SCOre of anxiety of the two group patients were measured and recorded before interview and before anesthesia.Results There were no difference in the observational indexes between the two groups before interview(P＞0.05),while after intervention(before anesthesia),the values of blood pressure and heart rate and the Score of anxiety in the intervention group were lower than those in control group (P＜0.01).Conclusion Preoperative systematic interview combined psychological care before operation is an effective nursing intervention mode,it can help patients who will receive thyroid surgery reduce the fluctuation of blood pressure and heart rate,and it can also relieve the preoperative anxiety.

Objective To investigate the diagnostic value of 64-slice CT and MRI in detection of abnormal sacroiliac joint changes in patients with early stage of ankylosing spodylitis (AS).Methods The 64-slice CT and MRI imaging data of the sacroiliac joint early diseases(grade 0 ～ Ⅱ lesion) for the 66 patients with clinical confirmed were reviewed retrospectively,of which MRI contrast enhanced was performed in 6 patients.Results CT showed grade zero lesion 15 cases,grade Ⅰ lesion in 20 cases and grade Ⅱ lesion in 31 cases.MRI revealed bilateral articular bone marrow edema in 52 cases,articular cartilage erosive destruction in 48 cases,fat accumulation of bilateral articular bone in 36 cases,articular bone erosive destruction in 31 cases.Bilateral synovial membrane enhancement was showed in all patients who underwent contrast enhanced.Conclusions MRI can detect acute inflammatory changes which can not display by MSCT.Compared with MSCT,MRI is more useful in detection of abnormal sacroiliac joint changes in patients with early stage of AS.

Objective To explore the related risk factors of cerebral hemorrhage complicated with stress ulcer (SU). Methods The clinical data of 1 185 patients with cerebral hemorrhage admitted to Department of Emergency Medicine of Nanjing General Hospital from March 2006 to March 2014 were retrospectively analyzed. Patients were divided into two groups according to whether patients complicated with SU or not. Data was collected within 8 hours after admission in two groups including gender,age,amount of bleeding,the bleeding site (basal ganglia,thalamus, brainstem,brain lobe,ventricle,subarachnoid,and cerebellum),disturbance of consciousness,acute physiology and chronic health evaluationⅡ(APACHEⅡ)score,systolic blood pressure(SBP),history of hypertension,and history of cerebral hemorrhage. The statistically significant risk factors found using univariate analysis was selected and was analyzed to find independent risk factors with multivariate logistic regression analysis. The receiver operating characteristic curve (ROC curve)was plotted to analyze the independent risk factors and evaluate their power of test. Results 1 185 patients with cerebral hemorrhage were enrolled in the study,293 cases occurred SU,accounting for 24.7%,and 892 cases without SU,which accounted for 75.3%. As shown by univariate analysis,risk factors for cerebral hemorrhage complicated with SU included age,amount of bleeding,the bleeding site,disturbance of consciousness,APACHEⅡscore,SBP. As to the site of bleeding,brain,thalamus,brainstem hemorrhage complicated with SU were higher proportion,45.3%(43/95),39.1%(63/161),36.9%(48/130),which were significantly higher than those of the lobes of the brain 〔26.2% (33/126)〕,cerebellum 〔18.8% (15/80)〕,basal ganglia〔16.1%(78/485)〕,arachnoid the inferior vena cava 〔12.0% (13/108)〕. Multivariate logistic regression analysis showed that amount of bleeding 〔odds ratio (OR)=3.305,P=0.001,95%confidence interval (95%CI)2.213-48.634〕,the bleeding site (OR=1.762,P=0.008,95%CI 0.123-2.743),SBP (OR=1.223,P=0.034,95%CI 0.245-2.812) were independent risk factors of cerebral hemorrhage complicated with SU. The area under the ROC curve (AUC)of amount of bleeding and SBP were 0.846 and 0.597,suggesting that amount of bleeding has moderate diagnostic value and SBP has low diagnostic value. Conclusions Cerebral hemorrhage patients with large amount of bleeding,the bleeding site in the ventricle,thalamus or brainstem,high SBP are of great risk. We should lower blood pressure and give preventive treatment for SU as soon as possible.

Objective To explore the appropriate pneumoperitoneum pressure in different surface area children during pediatric laparoscopic surgery,so as to attenuate the intederence with physiological function and avoid pneumoperitoneum correlative complications.Methods 120 patients underwent laparoscopic surgery were divided into three groups by different surface area:A(0.43～0.67m2),B(0.68～0.92m2),C(0.93～1.17m2).Each group was divided into two subgroups again by different pneumoperitoneum pressure:A1(4 mm Hg),A2(6mm Hg),B1(7mm Hg),B2(9mm Hg),C1(10mm Hg),C2(12 mm Hg).The cardiorespiratory function and blood gas analysis in different time point before and after pneumoperitoneum were monitored.Results The increase of PET CO2,Paw,HR,MAP and PaCO2 in A2,B2,C2 were more obvious than in A1,B1,C1(P ＜ 0.01).The eligible pneumoperitoneum pressure for A,B,C were 4,7,10mmHg respectively.The complications of gastric contents back-streaming and respiratory acidosis were 7 cases in A2,B2,C2 in all,and 3 cases in A1,B1,C1.Conclusion Using a compatible pneumoperitoneum pressure for different surface area children could attenuate the interference of physiological function and avoid pneumoperitoneum correlative complications.

Objective Acute coronary syndrome ( ACS) is frequently accompanied by chronic comorbidities , which may se-riously affect its prognosis .This study aims to investigate the value of the Charlson Comorbidity Index ( CCI) in predicting the outcome of ACS by assessing the impact of individual and post-weighted-assignment comorbid conditions of the disease . Methods We retro-spectively analyzed the clinical data on 1 096 cases of ACS treated in Jinling Hospital from January 2010 to March 2014 .We reviewed their general information , clinical presentations , complications , and previous treatments , calculated CCI , and used in-hospital mortali-ty as the index for judging the prognosis . Results Of the 1 096 patients, 73%were males (aged 64.2 ±12.9 years), 27% were females (aged 72.1 ±12.6 years), and 46.8% had comorbidities. Of the diseases included in the CCI system , previous myocardial infarction was the most frequent comorbidity (18.0%), followed by diabetes mellitus ( 14.7%), moderately to severe renal disease (7.1%), cerebrovascular disease (6.0%), and chronic lung dis-ease (6.0%).Single factor analysis revealed statistically significant differences between different CCI groups in such clinical indicators as history of coronary artery disease , history of hypertension , time between symptom onset and admission , hemodynamics , drugs adminis-tered (aspirin, P2Y12 blockers, ACEI/ARB or statins), and reperfusion therapy (P<0.05).Logistic regression analysis showed the strongest predictors of in-hospital mortality were heart failure (OR 1.88, 95%CI:1.57-2.25), metastatic tumor (OR 2.25, 95%CI:1.60-3.19), renal disease (OR 1.84, 95% CI:1.60-2.11), and diabetes mellitus (OR 1.35, 95% CI:1.19-1.19). Receiver operating characteristic curve analysis manifested that either CCI with age or CCI with age and gender was superior to CCI a -lone in predicting in-hospital mortality of ACS patients (AUC 0.761 [95%CI 0.748-0.773] and 0.756 [95%CI:0.743-0.768] vs 0.670 [95%CI:0.656-0.685]). Conclusion Heart failure, diabetes mellitus, renal disease, and metastatic tumors contrib-ute to the in-hospital mortality of ACS patients .CCI together with age and gender may help to assess the prognosis of the disease .

Objective To investigate the clinical value of the simple clinical score (SCS) in Emergency Department.Methods A total of 655 patients with critically illness admitted from July 1,2011through August 31,2011 were enrolled to evaluate the clinical application of SCS in emergency rescue room by analysis of the relationship between SCS and outcome of patients,and the correlation between each factor of SCS and the risk of death. Results The higher SCS,the higher hazard ratio for death.Differences in the hazard ratio for death among groups with different scores of SCS were statistical significance ( P ＜ 0.01 ).According to Chi-square test,there were significant differences in each factor ( except body temperature &unable standing or need Home Health Aide) among the groups of SCS ( P ＜ 0.05 ). Binary logistic regression analysis of each factor showed that age,diabetes,coma,pulse,systolic pressure and respiratory rate had significant correlation with patient mortality. After logistic regression analysis,age,diabetes,coma,pulse,systolic pressure and respiratory rate are significantly related to the mortality of patients.Conclusions The SCS scoring system is useful to make a precise evaluation of critically ill patients in the emergency department.When emergency rescue is carried out,particular stress should be focused on age,diabetes,coma,pulse,systolic pressure and respiratory rate.

Objective To explore the effects of intestinal trefoil factor ( ITF) on gastric mucosal epithelial cell proliferation and its possible molecular mechanism . Methods The cultured GES-1 cells were treated with ITF in the concentration of 100 ng/mL and 500 ng/mL in vitro, and then were observed using microscope for the morphological analysis .The Cell Counting Kit-8 ( CCK-8) was used to detect the proliferation activity of GES-1.The cultured GES-1 cells were treated with 100 ng/mL ITF and the specific inhibitor of PI3K/Akt signaling pathway LY294002 (15μmol/L) in vitro, and then were observed using microscope for the morphological analysis . The proliferation activity of treated GES-1cells was detected using CCK-8 and the expressions of p-Akt and Akt of PI3K/Akt signaling pathway were determined by Western blot . Results Compared with the control group , the proliferation activity of GES-1 cells in-creased after being treated with ITF and the higher concentration of ITF induced the higher proliferation activity .LY294002 inhibited the increased proliferation activity of GES-1induced by ITF.The data of Western blot indicated that ITF induced the expression of p -Akt and activated the P3IK/Akt signaling pathway to modulate the proliferation activity of GES -1 cells.However, LY294002 inhibited the PI3K/Akt signaling pathway and then decreased the proliferation activity of GES -1 cells. Conclusion ITF could promote the proliferation ac-tivity of GES-1 cells by activating PI3K/Akt signaling pathway .

Objective Though paraquat (PQ) is highly toxic, there is still no effective treatment for PQ poisoning .The aim of the article was to study the protective effect and mechanism of the p 38 mitogen-activated protein kinase ( MAPK) inhibitor SB203580 on PQ-induced acute lung injury in rats . Methods 72 SD rats were randomly divided into three groups ( n=24 ): normal saline (NS) group, PQ poisoning group and p38 inhibitor SB203580 intervention (PQ+SB) group.The arterial blood gas analysis, lung wet and dry ratio (W/D),the expression of tumor necrosis factor-α(TNF-α), the superoxide dismutase (SOD) level and the pathological changes of lung tissues were recorded at different time points after drug intervention . Results On the 1st , 3rd, 5th days after drug intervention in PQ group, the alveolo-arterial oxygen partial pressure difference (PA-aO2) [(45.67 ±4.17), (68.78 ±6.63), (80.23 ±7.12 ) mmHg ], the lung tissue TNF-αexpression (14.63 ±3.10], [18.24 ±2.98], [16.22 ±2.79] pg/mg) and W/D ([4.931 ±0.034], [5.020 ±0.064], [5.079 ±0.016]) in-creased gradually to a peak on the 3rd day, while the SOD level de-creased respectively on the 1st , 3rd, 5th days after drug intervention ([175.26 ±7.98], [167.57 ±8.05], [160.24 ±6.78] U/ug) (P<0.05).Compared with PQ group, PQ+SB group got a decrease in the PA-aO2([80.23 ±7.12] vs [44.17 ±4.16]), the lung tissue TNF-αexpression ([16.22 ±2.79] vs [9.48 ±2.72]) and W/D ([4.805 ±0.070] vs [5.079 ±0.016]) (P<0.05), while the pulmonary SOD level increased in comparison with PQ group ([125.89 ±6.65] vs [160.24 ±6.78]) (P<0.05). Conclusion The p38MAPK inhibitor SB203580 plays a certain protective role in PQ-induced acute lung injury by reducing inflammation and improving antioxidant capacity .

OBJECTIVETo analyze the associations between air pollution and adverse health outcomes on respiratory diseases and to estimate the short-term effects of air pollutions [Particulate matter with particle size below 10 microns (PM(10)), PM(10) particulate matter with particle size below 2.5 microns (PM(2.5)), nitrogen dioxide (NO₂), sulphur dioxide (SO₂) and ozone (O₃)] on respiratory mortality in China.

METHODSData related to the epidemiological studies on the associations between air pollution and adverse health outcomes of respiratory diseases that published from 1989 through 2014 in China, were collected by systematically searching databases of PubMed, SpringerLink, Embase, Medline, CNKI, CBM and VIP in different provinces of China. Short-term effects between (PM(10), PM(2.5), NO₂, SO₂, O₃) and respiratory mortality were analyzed by Meta-analysis method, and estimations were pooled by random or fixed effect models, using the Stata 12.0 software.

RESULTSA total of 157 papers related to the associations between air pollution and adverse health outcomes of respiratory diseases in China were published, which covered 79.4% of all the provinces in China. Results from the Meta-analysis showed that a 10 µg/m³ increase in PM10, PM(2.5), NO₂, SO₂, and O₃was associated with mortality rates as 0.50% (95% CI: 0-0.90%), 0.50% (95% CI: 0.30%-0.70%), 1.39% (95% CI: 0.90%-1.78%), 1.00% (95% CI: 0.40%-1.59%) and 0.10% (95% CI: -1.21%-1.39%) in respiratory tracts, respectively. No publication bias was found among these studies.

CONCLUSIONThere seemed positive associations existed between PM(10)/PM(2.5)/NO₂/SO₂and respiratory mortality in China that the relationship called for further attention on air pollution and adverse health outcomes of the respiratory diseases.
