Of the 250 cases of blunt abdominal trauma,15 cases of pancreatic lesions were complicatedwhich include 3 cases lacerated on the head of pan-creas, 5 on the body, 6 on the tail and one con-tused. The pancreatic bed drainage was performedfor one case, repair for 8 cases and pancreatic tailresection for 6 cases, In author's experiences, theroutinely inspecting the pancreas was carried outintra operatively, with blunt epigastric trauma, es-pecially the light red hemotoliquid was found bypericentesis. Operative method was classified frompancreatic bed drainage, repair and resection in ac-cordance with severity of the trauma, For prevent-ing the pancreatic juice fistula, the main pancreaticduct must try its best to be ligated. If the traumais on the head, a common bile duct and duodenumdecompression must be done.

Objective: To study the relationship between mental health and achievement motivation of teachers.Methods: 322 high school teachers completed SCL-90 and Achievement Motivation Scale.Results: The percent of high-score teachers with at least one SCL-90 subscale scored more than 3 is more than 5%.There is obvious correlation between the score of SCL-90 and the AMS's.Conclusion: The high level of achievement-seeking or the high level of failure-avoiding is harmful to the mental health of teachers.

Objective To explore the effect of nBiPAP on ET-1 of patients with overlap syndrome.Methods Levels of ET-1 in plasma of 25 cases of OS,20 cases of COPD were analysed by radioimmunoassay,and ET-1 in OS was measured before and after treatment.The relationship between ET-1 with SaO_2 during sleep was analyzed. Results (1)The ET-1 levels in plasma of OS group were significantly higher than those of COPD group before treatment(P

BACKGROUND: Posttraumatic stress disorder(PTSD) arises as a delayed and /or protracted response to a stressful event or situation of an exceptionally threatening or catastrophic nature. There have been reports about natural disasters causing PTSD, but there have been few reports about PTSDcaused by technological disasters. Our study investigated the mental status of those survivors after a serious explosion.OBJECTIVE: To investigate the characteristics and the factors of impact of PTSD caused by technological disasters.DESIGN: A case controlled study of the survivors of a momentous explosion.SETTING: A provincial mental health center.PARTICIPANTS: A serious explosion happened in Urumqi on September 8, 2000. Twenty-eight survivors(as the study group) who were still hospitalized for treatment 3 -5 months after the accident were involved in this study. And in the control group were 30 normal persons whose general demographic data were the same as those patients.METHODS: A psychiatrist told the subjects the following: The objective and meaning of the test, and explained the self-making questionnaire about their general condition, symptom checklist (SCL-90), self-rating anxiety scale (SAS), self-rating depression scale(SDS), cornell medical index(CMI), the questionnaire on dealing styles, the questionnaire on social support, and others-evaluating scale, incident effect scale(IES); a list of stress reaction symptoms.MAIN OUTCOME MEASURES:Main resulta:①Clinical feature of PTSD caused by the technological disaster.②the related factors to PTSD in the technologal disaster.Secondary results: Comparison of the results between the two groups in IES, CMI, SDS and SAS.RESULTS: A total of 22(79% ) survivors met the criteria as PTSD. There were significant differences in all the assessments(IES, CMI, SDS, SAS,SCL-90) between the study group and the control group (t =3.62-8.17, P ＜ 0.01 ) . The diagnosis of PTSD was positively correlated with the level of traumatic exposure( r = 0. 420, P ＜ 0. 05), and negatively correlated with the degree of satisfaction with the post-event solutions( r = 0. 420, P＜ 0.05), positively correlated with IES scoring and the level of heart pain ( r = 0. 389 - 0. 665, P ＜ 0. 01 ) . The total scores of IES were positively correlated with the level of exposure ( r = 0. 478, P ＜ 0.05 ).CONCLUSION: The incidence of PTSD after explosion was high, and its occurrence was related with the degree of exposure in the event and that of the satisfaction with the post-event solutions.

AIM:To investigate the effects of survivin inhibitor YM155 {4,9-dihydro-1-(2-methoxyethyl)-2-methyl-4,9-dioxo-3-(2-pyrazinylmethyl)-4,9-dihydro-1H-naphtho[2,3-d]imidazolium bromide} on the apoptosis, mito-chondrial membrane potential (Δψm) and cytochrome C (Cyt C) of retinoblastoma Y79 cells, and to analyze the mitochon-drial mechanisms of apoptosis .METHODS:Y79 cells were cultured in vitro and treated with YM155 at concentrations of 0, 0.5, 1, 2, 4 and 8 nmol/L.The cells in control group were treated without YM 155.The proliferation of Y79 cells were measured by CCK-8 assay and bromodeoxyuridine ( BrdU) labeling assay .Y79 cells were randomly divided into 4 groups:control group ( with equal volume of RPMI-1640 nutrient medium ) , positive control group ( 10 nmol/L topotecan ) , low-dose (1 nmol/L) YM155 group and high-dose (2 nmol/L) YM155 group.The effects of YM155 on the apoptosis, the changes of Δψm , the mitochondrial distribution and the protein level of Cyt C in the Y 79 cells were evaluated by flow cytom-etry with Annexin V-FITC/PI staining, JC-1 staining, immunofluorescence analysis and Western blot , respectively.RE-SULTS:Compared with control group , YM155 significantly inhibited the proliferation of Y 79 cells and induced apoptosis (P<0.05).YM155 significantly reduced Δψm of the Y79 cells, promoted Cyt C which released from mitochondria to the cytosol and reduced the protein level of Cyt C in the mitochondria (P<0.05).CONCLUSION:YM155 inhibits Y79 cell proliferation and induces apoptosis , and the possible mechanisms may be involved in the mitochondrium-mediated apoptotic pathway .

The therapeutic approaches for non-small cell lung cancer (NSCLC)patients with solitary bone metastases include surgery,radiotherapy,chemotherapy and so on.Recently,molecular targeted therapy such as the Denosumab has become a new option.Though there are so many options,the outcomes of the NSCLC with bone metastases are not so good.But for those with solitary bone metastases,radical treatment is necessary to improve the survival time and prognosis.

Objective To develop a rapid ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/ MS) for determination of 11 sedative-hypnotics in human plasma. Methods The plasma samples were extracted with dichloromethane:n-hexane:acetoacetate (5∶4∶1). The separation was performed on a Waters ACQUITY UPLC HSS T3 column (2.1 mm×100 mm,1.8 μm) using the mobile phase composed of acetonitrile-0.1% ammonium solution at a flow rate of 0.2 mL?min-1 in gradient elution mode. The detection was performed on a triple quadrupole tandem mass spectrometer by multiple reaction monitoring (MRM) via electrospray ionization (ESI) source in positive mode. Results Good linear relation was obtained over the investigated concentration range, with all correlation coefficients higher than 0.99. The limit of detection was 200 pg?mL-1 for dexzopiclone,and 10- 20 pg?mL-1 for other sedative-hypnotics. The intra- and inter-day RSD of 11 sedative-hypnotics were no more than 15.0%. The recoveries were in the range of 72.3%-108.0%, and the matrix effects were approximately 0.86- 1. 12. Conclusion The method is rapid, sensitive and reliable, and suitable for the simultaneous determination of 11 sedative-hypnotics in human plasma.
