Objective To investigate the changes and significance of I?B kinase-?(I?K-?) in the lung tissues of rabbits with hemorrhagic shock.Methods The expressions of I?K-? and NF-?B in the lung tissues and the concentration of tumor necrosis factor-?(TNF-?) in the plasma were measured by in situ hybridization(ISH),immunohitochemistry and enzyme linked immune adsorbent analysis(ELISA), respectively. And the pathological changes were examined with light microscope in lung tissues.Results In hemorrhagic shock group,the expressions of I?K-?(0 1685?0 0164)and NF-?B( 0 1469?0 0083)in lung tissues , the level of TNF-?(636 72?100 23) in the plasma were obviously higher than those of normal group [I?K-?(0 0427?0 0241),NF-?B(0 0358?0 0048),TNF-?(199 51?35 69)ng/L](all P

A metabonomics method based on gas chromatography_mass spectrometry ( GC_MS) was developed for detecting the significant differences of root exudates of the Cd hyperaccumulator Sedum alfredii under different treatments and study the effect mechanism of S. alfredii tolerating or accumulating the heavy metal Cd. The root exudates were collected after treatment for 4 and 8 days with 0 and 40μmol/L Cd. The collected solution was lyophilized and dissolved with methanol, and after derivatization with methoxyamine hydrochloride and N_methyl_N_trifluoroacetamide, the samples were analyzed by GC_MS. Principal component analysis ( PCA) and orthogonal partial least_squares discrimination analysis ( OPLS_DA) were carried out for pattern recognition and a clear separation among the different treatments was achieved. Twelve compounds which caused the separation among the different treatments were found and identified. With the change of treatments, the relative amount of these 12 compounds revealed different trends, which indicated that the Cd hyperaccumulator S. alfredii could adjust the secretion of root exudates to tolerate or accumulate the heavy metal Cd.

Objective To investigate the preventive mechanism of Anisodamine (654-2) on multiple organ dysfunction syndrome (MODS) of rabbits. Methods Rabbit model of MODS induced by hemorrhagic shock and endotoxin was used in this study. Twenty-four rabbits were randomly divided into the control group (C group) , hemorrhagic shock plus endotoxin group (M group) and 654-2 treatment group (T group). The expression of IKK-? of pulmonary alveolar macrophage (PAM) and kuffer cell(KC), the NF-?B activity of nuclear protein extracted from PAM and KC and the concentration of tumor necrosis factor-? (TNF-?) in the culture supernatant were measured by in situ hybridization (ISH), electrophoretic mobility shift assay (EMSA) and enzyme linked immune absorbent analysis(ELISA), respectively. Then the blood air, biochemical and pathological changes in visceral organs were examined in each groups. Results In PAM and KC of M group, The expression of IKK-? mRNA [(0 15?0 03);(0 17?0 04)], the activity of NF-?B [(1 49?0 30);(1 72?0 36)] and the secretion level of TNF-? [( 279 74?25 91);(300 05?30 86)ng/L] were significantly higher than those of control group (P

Objective To investigate the significance of I?B kinase-?(IKK-?) and the protective effect of Ligustrazini(Lig) in acute lung injury(ALI) induced by hemorrhagic shock(HS) in rabbits. Methods Thirty rabbits were randomly divided into three groups: HS plus endotoxin group(n=10), Lig treatment group(n=10) and the normal group(n=10). In situ hybridization and immunohitochemistry combined with in situ quantitative analysis were used to detect the distribution and relative contents of IKK-? and NF-?B in lung tissues. The plasma concentration of tumor necrosis factor-?(TNF-?) was measured by ELISA. Morphological change of the lung was observed by light microscopy. Results Compared with the normal group, the expression levels of IKK-?(0.223?0.080), NF-?B(0.162?0.021), and TNF-?(809.33?201.6) were obviously increased in HS plus endotoxin group(P

ObjectiveTo explore the prevalence of anxiety and its related social factors in undergraduate student,in order to provide scientific evidence for the prevention of anxiety in undergraduate.MethodsThe cluster random sampling was adopted for this study,and 965 college students from Zhengzhou University were investigated by Personal Report of Communication Apprehension,Simplified Coping Style Questionnaire,Toronto Alexithymia Scale,Perceived Social Support Scale and Self-Rating Anxiety Scale.Results①The anxiety detection rate of respondents was 19.3％.There were significant differences in the detection rate and severity of anxiety between genders(Male:27.0％,Female:10.2％ ) and grades( Freshman:16.4％,Junior:23.8％ ) in the college students (P ＜ 0.05).There were not significant difference in different family residence students anxiety detection rate and level(P ＞ 0.05 ).②The scores of communication apprehension ( ( 69.31 ± 12.32),( 65.25 ± 12.56) ),positive coping style( (20.84 ±5.10),(23.99 ±5.18) ),negative coping style( ( 11.03 ±4.15),(09.18 ±3.96) ),Toronto alexithymia( (74.97 ± 6.93 ),(70.31 ± 7.98 ) ) and perceived social support ( (53.14 ± 5.78 ),(57.02 ± 5.79) ) of the anxiety group were significantly different with those of the normal group (P ＜ 0.05).③The significant relationship was found among anxiety emotions and gender,positive coping style,negative coping style,Toronto alexithymia and perceived social support by using Logistic regression analysis (P＜ 0.05 ).ConclusionsThe prevalence of anxiety in undergraduate students is relatively high and it is related with multiple factors.In addition,social support,alexithymia and coping style have a close correlation with anxiety in undergraduates.

Objective To summarize extracorporeal membrane oxygenation (ECMO) in percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) with cardiac arrest,and to evaluate the clinical efficacy comparing with literature review.Methods 5 patients of AMI with cardiac arrest who proved invalid to conventional cardio-pulmonaryresuscitation (CPR),were successfully resuscitated with ECMO support,and underwent emergency PCI with stable hemodynamic status.Results In support of ECMO,4 patients were successfully resuscitated with stable hemodynamic status,and underwent primary PCI.The duration of ECMO support ranged from 42 to 220 h (average 126.6 h).3 patients discharged with full recovery,one patient didn't wean from ECMO successfully,and one died of respiratory failure.Conclusion Although mortality of AMI with cardiac arrest is high,early ECMO-assisted cardiopulmonary resuscitation and secondary PCI treatment increase the possibility of cardiac recovery,and provide conditions for emergency revascularization treatment.This reduces mortality in critical patients with AMI,and is an effective short term life support method.

Human embryonic stem ceIIs(hESC),characterized by unique capacities of seIf-renewaI and differentiation into cardiomyocytes and hepatocytes,can be used in new drug screening and drug safety evaIuation processes. Cardiotoxicity and hepatotoxicity are major obstacIes to deveIopment and marketing of new drugs. hESC-derived cardiomyocytes and hepatocytes have structuraI and functionaI characteristics,which can be used for cardiotoxicity and hepatotoxicity testing in vitroand for buiIding a drug safety evaIuation system invitrothat has the advantage of short experiment cycIes,smaII dose,Iow cost and few species differences. hESC-derived cardiomyocytes and hepatocytes have broad prospects of appIication in toxicoIogy.
