One hundred and five patients with non-ST segment elevation acute coronary syndrome were followed up for 1 year.They were assigned to the event group or non-event group according to the presence of endpoint events(cardiac death and nonfatM myocardial infarction).B-type natriuretic peptide level was measured at 30 days and 1 year and compared between the two groups.The results showed that the level of B-type natriuretic peptide was higher in the event group[(235±107)μg/L vs(154±49)μg/L at 30 days;(259±100)μg/L vs(143±57)μg/L at 1 year].Thus,B-type natriuretic peptide is an important prognostic factor for patients with non-ST segment elevation acute coronary syndrome.

Objective To investigate the clinical value of 3.0T MRI for hilarcholangioc-arcinoma diagnosis.Methods T Totally48 hilarcholangiocarcinoma patients from October 2011 to June 2015 underwent diagnoses by 3.0T MRI and 64-slice spiral CT,and then the diagnosing results were compared with those by surgery and pathological examination to determine the value of 3.0T MRI for hilarcholangiocarcinoma diagnosis.Results 3.0T MRI had the positioning accuracy (100％) and qualitative accuracy (95.83％) significantly higher than the positioning accuracy (79.17％) and qualitative accuracy (81.25％) (P＜0.05).In case of hepatic duct dilatation,CT found 35 cases of hilar masses,14 cases of lymphoma,5 cases of hepatic duct wall invasion and 9 cases of portal vein invasion,while 3.0T MRI displayed 44 cases of hilar masses,26 cases of lymphoma,13 cases of hepatic duct wall invasion and 30 cases of portal vein invasion.Conclusion 3.0T MRI has high positioning and qualitative accuracies when used to diagnosing hilarcholangiocarcinoma,behaves well in displaying hepatic duct dilatation,high resolution of soft tissues,and thus is worthy promoting clinically.

OBJECTIVE:To observe the efficacy and safety of edaravone combined with nimodipine in the treatment of acute large area cerebral infarction. METHODS:78 patients with acute large area cerebral infarction were randomly divided into control group (38 cases) and observation group (40 cases). Control group received aspirin platelet aggregation,reduced intracranial pres-sure,maintained water and electrolyte balance,decreased cerebral edema,Xuesetong for injection,Ginkgobiloba injection,lipid and blood pressurelowering,maintained blood sugar and other conventional treatment;observation group additionally received 30 mg Edaravone injection,adding into 100 ml 0.9% Sodium chloride injection by intravenous infusion (drip completed within 30 min),twice a day+12 mg Nimodipine injection,adding into 500 ml 0.9% Sodium chloride injection by intravenous infusion,once a day,with drip rate of 0.5-1 mg/h,for continuous 10 d,then received 40 mg Nimodipine tablet,orally,3 times a day. The treat-ment course for both groups was 15 d. Clinical efficacy,blood oxygen saturation (SpO2),hemoglobin (Hb),total hemoglobin (HbT),reduced hemoglobin(MHb)before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the incidence of adverse reac-tions was significantly lower tahn control group,the differences were statistically significant (P<0.05). Before treatment,there were no significant differences in SpO2,Hb,HbT and MHb in 2 groups (P>0.05). After treatment,the SpO2,HbT and MHb were significantly higher than before,and observation group was higher than control group,the differences were statistically signifi-cant(P<0.05);Hb was significantly lower than before,the differences were statistically significant(P<0.05),but there was no significant difference between 2 groups (P>0.05). CONCLUSIONS:Based on the conventional treatment,edaravone combined with nimodipine shows significant efficacy in the treatment of acute large area cerebral infarction,it can effectively recovery neuro-logical function damage and protect the brain tissue,which can reduce the incidence of adverse.

Objective Research on the correlation of dyslipidemia of civil aviation pilots and the TCM constitution aimed to explore that how professional environmental affects the lipid metabolism and the constitution.MethodsMeasure the lipid statusand TCM constitution of 656 pilots, and 496 of them with dyslipidemia were studied. The sample were stratified according to the age and the types of dyslipidemia, including young and middle-aged groups, only abnormal total cholesterol metabolism (TC), only abnormal triglyceride metabolism (TG), and both abnormal cholesterol and triglycerides metabolism groups and then the differences in prevalence of traditional Chinese medicine in different groups were analyzed and discussed. ResultsThe prevalence of abnormal lipid metabolism was 75.61% in 656 pilots. The top three TCM constitutions among the pilot with dyslipidemia were phlegm dampness constitution (35.89%), dampness heat constitution (33.06%) and deficiency of Yang(20.97%). If age was not considered, the prevalence of TCM constitutions were not significantly different between the groups of only abnormal TC and TG (P>0.05), while the prevalence of Yang deficiency and dampness heat constitutions of only either TC or TG abnormal group were significantly higher than those of the group of both abnormal TC, TG (χ2 values were 6.793, 5.077, P<0.05). Take age as considered, TC metabolic abnormalities in youth group, the prevalence of damp heat constitution of the only TC abnormal group was higher than both TC, TG abnormal group (χ2=7.637,P<0.01); and the prevalence of Qi deficiency and Yang deficiency constitution of the only TG abnormal group were higher than both TC, TG abnormal group (χ2values were 6.139, 7.525,P<0.05). In the middle-aged group, the prevalences of Yang deficiency and Qi stagnation constitution of only TC abnormal group were higher than only TG abnormal group (χ2 values were 9.750, 3.922,P<0.05), and the prevalence of Yang deficiency of only TC abnormal group was higher than both TC, TG abnormal group (χ2=5.208,P<0.05). The prevalence of Yang deficiency of both TC, TG abnormal group was higher than only TG abnormal group (χ2= 4.489,P<0.05). Conclusions The result showed high prevalence of dyslipidemia in the population of civil aviation pilots. Age and lipid metabolism status could affect the types of TCM constitution. Damp-heat constitution was the common type of TCM constitution in the population of the young pilot, and Yang deficiency and Qi stagnation constitution were the common types in the population of middle-aged people whose lipid metabolism were disorder. The group of only abnormal TC influence on TCM constitution more than both abnormal TC and TG.

Objective To explore the efficacy,safety and life quality of patients of morphine hydrochloride sustained-release tablets combined with celecoxib in the treatment of advanced lung cancer with moderate to severe cancer-induced pain.Methods A total of 247 patients of advanced lung cancer with moderate to severe cancer-induced pain were randomly divided into combination therapy group (n =127) and morphine monotherapy group (n =120) using simple random sampling digital table method.The differences of dose,efficacy,adverse drug reactions and life quality between the two groups were analyzed.Results In achieving similar analgesic effect,the average maintenance dose of morphine in combination therapy group was (52.51 ±19.92)mg/d,lower than that in monotherapy group [(58.75 ±20.64)mg/d,t =-2.414,P =0.017].The incidence of constipation in combination therapy group was 34.6％,lower than that in monotherapy treatment group (47.5 ％,x2 =4.218,P =0.040).The life quality of the two groups were improved,and the life quality improvement rate in combination therapy group was 59.8％,higher than that in monotherapy treatment group (43.3％,x2 =6.736,P =0.009).Conclusion Morphine hydrochloride sustained-release tablets combined with celecoxib is effective in the treatment of moderate to severe cancer pain,which can reduce the dosage of morphine and reduce adverse reaction,so as to improve the life quality of the patients with advanced lung cancer.

Objective To evaluate the functional changes of visual cortex (V1) in patients with primary open angle glaucoma (POAG) by fMRI retinotopic mapping technology. Methods Fifteen POAG patients and 15 healthy volunteers underwent stimulations with fMRI retinotopic mapping stimulus and contrast-reversing checkerboard patterns stimulus on a Siemens Trio 3.0 T MRI whole-body scanner for functional data collection. Comparisons of V1 fMRI responses between the glaucomatous eyes and the healthy eyes of the patients were carried out using paired samples t-test, while independent samples t-test was used to compare V1 fMRI responses and activations between the healthy eyes of patients and the age-, gender- and side- matched eyes of normal people. Differences of V1 cortical functions and visual functions were analyzed by linear correlation analysis when the glaucomatous and the healthy eyes were simulated individually. Results (1) V1 fMRI responses of the individually stimulated glaucomatous eyes[(1.24±0.72)%]were weaker than those of the healthy eyes[(2.18±0.93)%](t=4.757,P<0.01). Comparisons of V1 fMRI responses between the glaucomatous eyes and matched eyes of normal people, as well as between the healthy eyes of patients and the matched eyes of normal people, were performed respectively: the responses in the glaucomatous eyes[(1.24±0.72)%]were weaker than those in the matched eyes of normal people[(2.01±0.65)%](t=-3.011,P<0.01). There was no statistical difference of the responses between the healthy eyes from patients[(2.18±0.93)%]and the matched eyes of normal people[(1.95±0.75)%](t=0.742,P＞0.05). (2) Differences of V1 cortical functions were negatively correlated with those of visual functions in the individually stimulated glaucomatous and healthy eyes (r=-0.887, P<0.01). (3) The activated area indexes of V1 cortexes in the healthy eyes from patients (0.72±0.12) were lower than those in the matched eyes of normal people (0.85±0.09) (t=-3.801, P<0.01). Conclusion Cortical function impairment was in accordance with visual function impairment in glaucoma. Located and quantified measurement with fMRI retinotopic mapping was a useful method for clinical follow-up and evaluation of functional alteration of glaucomatous visual cortex, and a potentially useful means of studying trans-synaptic degeneration of visual pathways of in vivo glaucoma.

Objective To investigate CT and MRI features of hepatic sclerosed hemangioma (HSH).Methods CT and MRI findings were retrospectively reviewed in 20 cases of HSH,all of which were confirmed pathologically after hepatic surgery.Twenty patients underwent CT scan,4 patients underwent MRI.Meanwhile,the enhancement pattern and signal intensity were analyzed either.Results Twenty patients showed main part of tumor was hypo-attenuating on CT plain scanning,and 16 patients showed the central area of tumor was markedly more hypo-attenuating on CT plain scanning.After administration of intravenous contrast media,multifocal linear or small nodular enhancement in the peripheral area was seen during the arterial phase on 16 patients of HSH.Venous phases showed centripetal enhancement or spread around the nodules enhancement which continued to delayed phases with low density of no enhancement in the lesion area.Four patients showed no obvious enhancement on arterial phases and slight separation sample enhancement at the edge or inside of the lesions with a wide range of non enhancement areas on venous phase and delayed phase.Four patients were performed MRI examination,the lesions demonstrated hypointensity with a lower signal area on T1WI,hyperintensity with a higher signal intensity area on T2WI.The DWI sequence of b value were 0,150,800 s/mm2,all of which were obviously hypointensity.The edge of lesions showed small nodular enhancement on arterial phase,irregular concentric enhancement on venous phase and delayed phase,and there was no enhancement area with lower signal in the center of the lesion.Conclusions The enhancement pattern of HSH different from cavernous hemangioma,with a larger non enhancement area in the center of the lesions and similar to other hepatic masses with central scar,differential diagnosis dependence on CT and MRI dynamic enhanced scan.

Objective To study the relationship between behavioral problems and family environment in preschool-age children. Methods Children between 4-6 years of age in the kindergartens of Zhongshan city were randomly selected. Child Behavior Checklist (CBCL) was used to assess the behavioral problems in children, and self-designed general situation question-naire and Family Environment Scale-Chinese Version (FES-CV) were applied to evaluate the family environment. Results A total of 3445 children were enrolled and 29.87%children showed behavioral problems. There were signiifcant differences in the scores of feeling expression, family conlfict, intelligence, recreation, organization and control between children with and without behavior problems (P<0.001). The scores of feeling expression, intelligence, recreation, organization and control were signiif-cantly higher and the score of family conlfict was lower in healthy children in comparison with children with behavior problems. Through multivariate logistic regression, it was suggested that female (OR=2.04), non-urban population (township OR=1.45, rural OR=1.51), non-local Zhongshan resident (OR=1.39), father’s low educational level (technical secondary school OR=1.77, junior high school OR=2.17, primary school and below OR=3.24), discipline styles (indulgent OR=1.47, mixed OR=1.37), family conlfict (OR=1.13) were independent risk factors for behavioral problems (P<0.05). Mother’s age over 30 (OR=0.74) or over 40 (OR=0.46), feeling expression (OR=0.94) and intelligence (OR=0.87) were independent protective factors for behavioral prob-lems (P<0.05). Conclusions Behavioral problems in preschool-age children are closely related to family environment, which needs to be paid more attention.

Theme 2: Difficulties and challenges in the application of expressive writing intervention: physical discomfort affects the compliance of patients, poor economic status affects the enthusiasm of patients to participate, poor social and family support affects the willingness of patients to participate, and literacy and writing habits affect the completion of participation.Conclusions:The application of expressive writing intervention promotes the psychological and social functional rehabilitation of patients with laryngeal cancer post total laryngectomy and has satisfactory effects and certain feasibility. The researchers should fully consider the influencing factors of intervention and optimize the plan in the future.

The subtype H9N2 avian influenza virus greatly threatens the Chinese poultry industry, even with annual vaccination. Waterfowl can be asymptomatically infected with the H9N2 virus. In this study, three H9N2 virus strains, designated A/Goose/Jiangsu/YZ527/2011 (H9N2, Gs/JS/YZ527/11), A/Goose/Jiangsu/SQ119/2012 (H9N2, Gs/JS/SQ119/12), and A/Goose/Jiangsu/JD564/2012 (H9N2, Gs/JS/JD564/12), were isolated from domestic geese. Molecular characterization of the three isolates showed that the Gs/JS/YZ527/11 virus is a double-reassortant virus, combining genes of A/Quail/Hong Kong/G1/97 (H9N2, G1/97)-like and A/Chicken/Shanghai/F/98 (H9N2, F/98)-like; the Gs/JS/SQ119/12 virus is a triple-reassortant virus combining genes of G1/97-like, F/98-like, and A/Duck/Shantou/163/2004 (H9N2, ST/163/04)-like. The sequences of Gs/JS/JD564/12 share high homology with those of the F/98 virus, except for the neuraminidase gene, whereas the internal genes of Gs/JS/YZ527/11 and Gs/JS/SQ119/12 are closely related to those of the H7N9 viruses. An infectivity analysis of the three isolates showed that Gs/JS/SQ119/12 and Gs/JS/YZ527/11 replicated well, with seroconversion, in geese and chickens, the Gs/JS/JD564/12 did not infect well in geese or chickens, and the F/98 virus only infected chickens, with seroconversion. Emergence of these new reassortant H9N2 avian influenza viruses indicates that these viruses can infect both chicken and goose and can produce different types of lesions in each species.
