Objective To investigate the adverse reactions influence factors of deep sedation anesthesia.Methods 120 cases with elective gastrointestinal tumor resection were chosen and given deep sedation anesthesia.The occurrence of intranperative bemodynamic changes at each time point and adverse reaction were statistically analyzed.Results SBP,DBP,HR and SpO2 values at different anesthesia time point had significant differences (F =9.688,10.258,7.586,8.992,all P =0.000).26 cases had intraoperative and postoperative adverse reactions,the incidence was 21.7％,8 cases with hypotension,4 cases with bradycardia,6 cases with nausea and vomiting,2 cases with apnea,6 cases with other adverse reactions.No death and serious adverse reactions occurred.Senility,depth anesthesia application history,psychological stress and obesity were risk factors of intraoperative and postoperative adverse reactions of gastrointestinal tumor by deep sedation anesthesia(OR values =9.806,0.119,0.105,10.521,all P ＜0.05).Conclusion Adverse reaction incidence of gastrointestinal tumor by deep sedation anesthesia was high,and more performance for hemodynamic response,anesthesiology doctors could improve patients prognosis by regulating the perioperative risk factors.

Objective To explore the application value of susceptibility weighted imaging (SWD) in the Parkinson disease (PD) diagnosis by analysis the changes of brain iron content of the basal ganglia and red nucleus.Methods Totally 56 cases of patients with PD and 40 cases of normal control group were diagnosed by SWI with the 3.0 T magnetic resonance imaging system,the corresponding phase image by using SWI processing software was obtained,the signal values of the various regions of the brain basal ganglia and red nucleus were measured and compared.Results In comparison of PD group with normal control group,the signal values showed differences in caudate (0.05±0.01 vs.0.04±0.01,t=1.991),putamen(-0.42±0.13 vs.-0.25±0.07,t=2.544) and globus pallidus(-0.23± 0.07 vs.-0.11±0.02,t=2.893) (all P＜0.05).Conclusions Determining the iron deposition signal of the various regions of the brain basal ganglia by SWI is valuable in the clinical diagnosis of Parkinson's disease.

Background and purpose:HIF-1? (Hypoxia-inducible factor-1?) is an important transcription factor under hypoxia condition. It plays the role of dominating the expressions of correlative genes. It also promotes tumor deterioration, tumor metastasis and tumor invasion. The molecular role of HIF-1? has been intensively studied in cancer basic research. This article is to investigate the expression of HIF-1? under hypoxic and reoxygenation induced by CoCl_ 2 and the impact of hypoxia-inducible transcription factor-1? on human ovarian carcinoma cell line HO-8910PM. Methods:Semi quantitative reverse transcription-polymerase chain reaction (RT-PCR) is performed to detect the expression of HIF-1? mRNA in human ovarian carcinoma cell HO-8910PM exposed during the phase of hypoxia and reoxygenation. The relations of the quantity-efficiency and the time-efficiency were analyzed. The effects of HIF-1? gene on the proliferation, invasion and adhesion of HO-8910PM cell were estimated by either MTT, Boyden cell or cell adhesion tests.Results:There was endogenous expression of HIF-1? in human ovarian carcinoma cell line HO-8910PM. RT-PCR show that over-expression of HIF-1? mRNA could be measured under hypoxia induced by CoCl_ 2 (P

AIM To investigate the effects of p38 MAPK signaling on diallyl disulfide ( DADS ) induced apoptosis in CNE2 cells. METHODS Morphological changes and quantification of apoptotic cells were determined under fluorescence microscope after a 24 h treatment of CNE2 by DADS. Cell viability was determined with MTT method. Apoptosis detection was taken to the cells on flowcytometry. The expression of phospho p38 MAPK was measured by Western blotting. RESULTS After treatment with DADS at 50～150 ?mol?L -1 for 24 h,DADS elicited typical apoptotic morphologic changes (chromatic condensation, nucleus fragmentation). The amount of apoptosis cells increased in a concentration dependent manner but cell cycle arrest did not at 50～150 ?mol?L -1 ,incubation of CNE2 with DADS for 24 h also induced phospho p38 MAPK expression in a concentration dependent manner. Interestingly, DADS induced apoptosis was markedly increased by preincubation with SB203580, a specific p38 MAPK inhibitor,and increased the expression of phospho p42/ p44 CCDPK in a concentration dependent manner. CONCLUSION DADS activates p38 MAPK,and phospho p38 MAPK signaling appears to play protective roles in DADS induced apoptosis in CNE2.

Macrophage-inducible C-type lectin (mincle receptor) is a novel unclassical C-type lectin receptor member,which is mainly expressed on the surface of antigen presenting cells.Under the stimulation of fungus,mycobacterium tuberculosis and necrotic cells,mincle receptor plays anatural immune effect in host body by binding to relevant ligand and activate nuclear factor-κB (NF-κB) signaling pathway,which promotes the expression of many inflammatory factors.Up to now,the laboratory and clinical studies on mincle receptor and infected diseases is being a hot topic.However,these study is lack in ophthalmology.Understanding the association of mincle receptor to infected eye diseases will offer a new approach to the immunotherapy.The basic concept,acting mechanism,its relationship to inflammatory eye diseases and outlook in ophthalmology of mincle receptor were reviewed in this paper.

Diabetic retinopathy (DR) is one of the common and serious diabetic complications,with a complex nosogenesis.Studies have shown that transforming growth factor-β (TGF-β) participates in the occurrence and development of DR,and Smads protein is able to mediate and activate TGF-β/Smads signal transduction pathway and further involves in the pathogenesis of DR.Smurf is one of the ubiquitin ligases in ubiquitin-proteasome pathway,and it is clarified to regulate TGF-β/Smads signal transduction pathway degradation.At present,the study on the relationship between TGF-β/Smads pathway and DR has made great progress.The role of ubiquitin-proteasome pathway regulating TGF-β/Smads signal transduction pathway in DR is reviewed in this article.

Objective To improve the DXC series of psychology test instrument and its supporting software.Methods The nRF905 chip and STC89LE516AD chip were used to design the question system.Results Such shortcomings in the DXC-5 system were improved as overweight,too many link-wires,too much time in the initial deployment,etc.Conclusion The system can be used to select not only flight personnel and cosmonauts,but also personnel in other special professions.

Acute pancreatitis is a common serious disease, and considered to be inflammatory disturbance course. The early storm of proinflammatory cytokine releasing evokes systemic inflammatorome response syndrome (SIRS) ,and leads to multiple organ dysfunction syndrome(MOPS). At the late phase, because massive of antiin-flammatory cytokines initiate compensatory anti-inflammatory response syndrome ( CARS), the body immune func-tions suffer suppressed and result in infection or toxemia. So reestablishing baulance of SIRS/CARS has considera-ble clinical meaning to the AP patient morbidity. In this article, we will overview the relevant factors and mecha-nisms of the SIRS/CARS induced by AP.
