ObjectiveTo investigate the effect of mild hypothermia on neuron specific enolase (NSE) and superoxide dismutase (SOD) in serum of patients with large-area cerebral infarction.Methods160 cases with large-area cerebral infarction were divided into the treatment group and control group with 80 cases in each group. Patients of the control group were treated with routine therapy. Those of the treatment group were added with mild hypothermia therapy (MHT). The scores of NIHSS were assessed and NSE and SOD in serum were examined before treatment and 7, 14 and 30 days after treatment in two groups.ResultsThe NIHSS score of the treatment group was significantly lower than that of the control group ( P<0.05), and NSE level decreased, SOD vitality increased in the treatment group. Other indexes such as respiratory, pulse, serum kalium and etc of two groups were not different ( P>0.05).ConclusionMHT can improve he nerve function of patients with large-area cerebral infarction recovering and improve prognosis.

Objective To detect the changes and the clinical significance in plasma protein-complement factor H-related protein 2 (CFHR2) in pulmonary arterial hypertension (PAH) associated with congenital heart disease (CHD) children.Methods Various types of 66 CHD patients with or without PAH and 16 healthy children(healthy control group) were studied,including 11 ventricular septal defects (VSD) with PAH (VSD-PAH),11 isolated VSD,11 atrial septal defects with PAH (ASD-PAH),11 isolated ASD,11 mixed type of heart defects [two or more defects of VSD,ASD and patent ductus arteriosus (PDA)] with PAH (Mix-PAH) and 11 cases without PAH (Mix).CFHR2 was validated by enzyme linked immunosorbent assay in the sample plasma.Results Compared with the healthy control group,the CFHR2 concentration in VSD-PAH patients [(189.10 ±24.01) μg/L vs.(42.99 ±4.53) μg/L,t =4.975,P ＜0.01] and VSD patients [(189.10 ±24.01) μg/L vs.(165.00 ±23.17) μg/L,t =2.661,P ＜ 0.05] were lower.The CFHR2 protein was also confirmed to be decreasing significantly in VSD-PAH patients compared with VSD patients (t =4.698,P ＜ 0.01).The plasma CFHR2 level in ASD-PAH patients [(189.10 ± 24.01)μg/L vs.(70.92 ± 8.27) μg/L,t =3.951,P ＜0.01] and ASD patients [(189.10 ±24.01) μg/L vs.(72.48 ± 8.99) μg/L,t =3.880,P ＜ 0.01] were significantly lower than those in the healthy control group,although there was no significant difference between ASD-PAH and ASD patients (t =0.128,P ＞ 0.05).The plasma CFHR2 level in Mix-PAH patients [(189.10 ± 24.01) μg/L vs.(83.23 ± 15.96) μL,t =3.314,P ＜ 0.05] was significantly lower than that in the healthy control group,while Mix patients [(189.10 ±24.01) μg/L vs.(170.40 ±33.15) μg/L,t =0.468,P ＞ 0.05] had no difference compared with the healthy control group,but had statistical significance with M ix PAH group (t =2.370,P ＜ 0.05).Conclusions The decrease of CFHR2 protein may demonstrate the deficiency of the immune system and coagulation mechanism in these patients and can be consi-dered as biomarker of CHD-PAH disease.

Objective To observe the ultrastructure location of Huntingtin-associated protein 1(HAP1) in rat adrenal medulla and the effect of cold stress on the expression of HAP1 in rat adrenal medulla. Methods Fourteen healthy male Wistar rats were used in the present study and among them two rats were used for immune electron microscopy and twelve rats for cold stress experiment. In the cold stress experiment, animals were divided into control and cold groups randomly with six rats in each group. During the experiment, rats were housed in a room at the temperature of 4℃ for 12 hours and then immunohistochemistry and Western blotting were used to measure the expression of HAP1 in adrenal medulla. Results By using the immune electron microscopy, the results showed HAP1 was located on the external membrane of secretory vesicles of adrenal medulla and their membranous organelles. The expression of HAP1 in adrenal medulla of cold group significantly decreased as compared with that of control group ( P <0.01). Conclusion HAP1 might be related with the adrenal medulla cells endocrine granula and involved in the transmission and release of adrenaline or noradrenaline in secretory granule.

Objective To optimize the processing conditions of Manchuiran Dutchmanspipe Stem with alkali. Methods The combination of radial basis function ( RBF) and response surface methodology ( RSM) was used to investigate the influence of NaHCO3 , concentration, duration and cycles of processing on the content of aristolochic acid. Results The optimal process was achieved when Manchuiran Dutchmanspipe Stem was soaked for 3 cycles in 0. 05 mol·L-1 NaHCO3 solution, for 24 hours in each cycle. The removal rate of total aristolochic acid approached to 83. 74%. Conclusion The combination of RBF and RSM provided a new method and good guidance for further toxicity attenuation for Manchuiran Dutchmanspipe Stem.

AIM: To construct the eukaryotic expression vector CD80-IgG by fusing the cDNA encoding extracellular portion of murine CD80 to the 5'-terminus of cDNA encoding Fc fragment of murine immunoglobulin G1 and to express the fusion protein in Chinese hamster ovary (CHO) cells. METHODS: The two cDNAs was amplified by PCR respectively from plasmid pcDNA/B7 containing the full-length cDNA of murine CD80 from murine spleen cells, and cloned to the eukaryotic expression vector pcDNA3.0 by directional cloning. The resultant recombinant plasmid pcDNA/CD80-IgG was transfected into CHO cells with liposome transfection reagent. The stably expressing cells were obtained by G418 screening. Western blot, Dot ELISA, and flow cytometry were used to detect the expression of the fusion protein and its immunological activity. RESULTS: DNA sequencing verified the correction of the construction of recombinant plasmid pcDNA/CD80-IgG. The expressed fusion protein was detected in the supernatant of transfected CHO cells and the molecular weight of the protein was similar to what we expected. Its immunological activity was also established. CONCLUSION: The recombinant plasmid pcDNA/CD80-IgG was successfully constructed and it expressed the fusion protein CD80-IgG.

ObjectiveThis article investigates the distribution of psychological models and its association with asthma by means of examining the psychological models of asthmatic patients.MethodsUsing 80.8 test table provided by the Institute of Applied Psychology of Suzhou University to exam the psychological models of two hundred cases in their non- acute episodes. Results From two hundred asthmatic patients we can notice the association between psychological models and the degree of asthma. In severe asthmatic patients, most was dispersed - puzzle model, occupying 65.3% (17/26),the second was intermediate model 30.7% (8/26). The majority in medium asthmatic patients was intermediate model, taking 53% (53/100), the second was dispersed-puzzle model, 34% (34/100).The easy-disturbance model was the most in mild ones, 51.4% (38/74), the intermediate model was the second, 25.6%(19/74). ConclusionThere are different psychological models in asthmatic patients. In treatments, except the medical therapy, we should direct and take active care of the patients in psychological health aspect.
