AIM: To observe the effect of LPS on CIAS1 gene expression and to analyze the function-structure relationship of its mutation region, the NACHT domain of cryopyrin. METHODS: RT-PCR was used to detect the expression of CIAS1 gene in human leucocytes in the presence of LPS. The methods of molecular modeling and bioinformatics were used to observe the relationship of the structure-function of NACHT domain in human CIAS1 gene. RESULTS: LPS increased CIAS1 mRNA expression in a dose-dependent manner. However, the stimulation with LPS at a concentration of 100 mg/L at different time points showed the pattern of early down-regulation and later up-regulation of CIAS1 mRNA expression. The sequence analysis suggested that the motifs Walker A and Walker B, to which the ATP and Mg~ 2+ can bind, were found in the NACHT domaim of CIAS1 gene encoded product cryopyrin. The main points of the disease-associated mutation showed the close relation in sequence and structure to these motifs. The binding sites of Ca~ 2+ and polysaccharide were observed in the leucine rich repeats region of cryopyrin. CONCLUSION: Cryopyrin may act as an important regulator in inflammation. LPS induces human leukocytes to express the CIAS1 gene product.

Objective To investigate the levels of serum macrophage inflammatory protein-1α (MIP-1α),inflammatory factors and pulnonary function in patients with asthma,and the correlation between thenm.Methods Eighty patients with asthma were selected who were treated in our hospital from March 2015 to August 2016,and the data of 80 healthy adults were selected as control.The differences of serum MIP-1α,inflammatory factors,imnmunoglobulin and lung function were observed in two groups.The correlation between MIP-1α and inflammatory factors,lung function and immunoglobulin were analyzed.Results The levels of MIP-1α,interleukin (IL)-6,and tumor necrosis factor-α (TNF-α) in patients with asthma were significantly higher than those in control group (t =-207.04,-33.209,-55.132,P ＜ 0.01);The levels of forced vital capacity (FVC),the forced expiratory volume in one second (FEV1),FEV1/FVC,maximal mid expiratory flow (MMEF),and peak expiratory flow (PEF) in the asthma group were significantly lower than those in the control group (t =17.100,39.154,22.791,25.391,19.356,P ＜ 0.01).The IgG and IgM of asthma group were significantly lower than those of the control group (t =9.564,7.528,P ＜ 0.01).The IgE level was significantly higher than that of the control group (t =-82.683,P ＜0.01).The level of MIP-1α was positively correlated with the levels of IL-6,TNF-0 and IgE,and negatively correlated with FVC,FEV1,FEV1/FVC,MMEF,PEF,IgG and IgM in patients with asthma.Conclusions The level of serum MIP-1 α in asthmatic patients is high,and is closely related to the inflammatory cytokines and lung function in patients with asthma.

Aim To study the effect of bioactive compounds from paecilomyces tenuipes(BCPT) on AVP content of hypothalamus,pituitary and expression of AVP mRNA of hypothalamus and behaviour in chronic unpredictable stress model of depression in rats.Methods The depression animal model was induced by chronic unpredictable stress.The behaviour of rats was tested in the open field.The effect of BCPT on AVP content in hypothalamus and pituitary was tested by radioimmunoassay.RT-PCR was used to test the expression of AVP mRNA in hypothalamus.Results BCPT could decrease the expression of AVP mRNA of hypothalamus and decrease AVP content of hypothalamus and pituitary in chronic stressed rats obviously.BCPT could increase ambulation and rearing score of chronic stressed rats in the open-field test.Conclusion BCPT exhibited an antidepressant-like effect may in part be associated with the decreasing AVP content of hypothalamus and pituitary,and the expression of AVPmRNA of hypothalamus in chronic unpredictable stress model of depression in rats

Aim Exploration of the effects of bioactive compound from paecilomyces tenuipes (BCPT) on the behavior, ultrastructure of hippocampus, and expressions of BDNF and Bax of cerebral cortex in CUS rats. Methods The depression model rat was induced by chronic unpredictable stress(CUS). The Open field test was used to observe the behavior of CUS rats. The expressions of BDNF and Bax of cerebral cortex were studied using immunohistochemical method, and average optical density of cortical neuron was calculated by image analysis. Morphology of hippocampus was observed by transmission electron microscope. Results Compared with model group, BCPT could obviously increase the activity of ambulation and rearing and the number of positive neuron of BDNF, decrease the number of positive neuron of Bax, and effectively prevent pathological damage induced by chronic unpredictable stress. Conclusion BCPT may exhibit the effects of antidepression, up-regulate the expression of BDNF, down-regulate the expression of Bax, and improve of the ultrastructure of hippocampus.

Objective To explore the effect of PDCA circulation on the effective utilization of the disposable articles in the operating room.Methods 9,362 aseptic articles for 446 operations in the departments of general surgery and hepatobiliary surgery during January to May 2012 were put in the pre-experiment group,in which PDCA circulation was not used.Another 11,973 articles for 501 operations in the same departments during June to November 2012 were set as the post-experiment group,in which PDCA circulation was used.The two groups were compared in terms of the effective utilization rate and the degree of doctor’s satisfaction with the nurses in the operation room.Result After the implementation of PDCA circulation,the effective utilization rate and the degree of doctor’s satisfaction were both significantly higher than before the implementation(both P<0.05).Conclusion PDCA circulation for the management of sterile disposable articles in the operation room may effectively improve the utilization rate of disposable articles, reduce wasting of articles and safe resources.

Objective To study the morbidity rule of community trauma and pre-hospital care mea-sures so as to improve the pre-hospital care performance. Methods 962 cases who received pre-hospital care by "120" commanding center in our hospital were retrospectively analyzed by means of self-designed questionnaires. Results The features of community trauma were mainly multiple trauma caused by traffic accidents, the main pre-hospital care measures included bandaging, hematischesis, pexia, aspiration of oxy-gen,intravenous injection, cardiopulmonary resuscitation,tracheal intubation and cricothyroid puncture,a-mong which bandaging, hematischesis and pexia accounted for 92.7 per cent. Conclusions Early and rapid treatments to the wounded patients, and correct medical rescue are very important. They are the two key factors to promote the success rate of rescue. At the same time, sound nursing management, correct medical treatment and nursing coordination are also critical aspects.

Objective To study the value of the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in gene diagnosis on spinal muscular atrophy (SMA).Methods PCR-RFLP method was used to detect the homozygous deletion of the exon 7 or exon 8 of SMN gene in 20 SMA patients of Type Ⅰ,Ⅱ,Ⅲ and 15 normal individuals.Results Homozygous deletion of exon 7 and exon 8 of the SMN gene were all identified 7/7 in SMA TypeⅠpatients, and 5/5 and 4/5 respectively in SMA Type Ⅱ patients, but only 1/8 of SMA Type Ⅲ patients, and no homozygous deletion was found in the normal controls.Conclusions PCR-RFLP might be recommended as an effective diagnosis for spinal muscular atrophy Type Ⅰand Ⅱ patients, whereas the method might not be as useful in Type Ⅲ as in Type Ⅰand Ⅱ for the gene diagnosis.
