Objective To study the correlation between the level of serum high sensitivity C-reactive protein (hs-CRP) and induced sputum cell counts,pulmonary function and asthma control test (ACT) in order to investigate the clinical application value of serum hs-CRP for the acute exacerbation bronchial asthma patients.Methods Thirty acute exacerbation bronchial asthma patients were collected as asthma group,14 healthy people during the same period were collected as control group.The fasting serum hs-CRP was examined in control group and before and after treatment of 5-7 d in asthma group.The induced sputum was obtained by ultrasonic atomizer 4.5％ sodium chloride,and the percentage of eosinophils (EOS％),neutrophil,macrophages,lymphocytes was calculated.The pulmonary function index was determined in control group and before and after treatment in asthma group.ACT score was performed in asthma group.The correlation between the serum hs-CRP and induced sputum differential leukocyte count,the pulmonary function index and ACT score was analyzed by Spearman correlation analysis.The effect of the serum hs-CRP and induced sputum EOS％ on inflammatory response of acute exacerbation bronchial asthma was evaluated by receiver operating characteristic (ROC) curve analysis.Results Two cases were excluded in asthma group.The serum hs-CRP before and after treatment in asthma group was higher than that in control group[4.18(2.12-11.12) and 3.40(2.02-8.91) mg/L vs.1.48(1.03-4.81) mg/L,H =18.939,P＜ 0.01].The serum hs-CRP before treatment was higher than that after treatment in asthma group (P ＜ 0.01).In asthma group,the serum hs-CRP had positive relationship with induced sputum EOS％ (r =0.849,P =0.000).There were negative correlations between the serum hs-CRP and the pulmonary function index such as one second forced expiratory volume percent predicted,one second forced expiratory volume occupied vital capacity ratio,maximum mid-expiratory flow percentage of predicted (r =-0.617,-0.559,-0.398,respectively,P =0.000,0.002,0.036,respectively).It was also found that the serum hs-CRP and ACT score had the remarkable Spearman linear correlation (r =-0.511,P =0.005).The area under the ROC curve of the serum hs-CRP was 0.713 (P =0.003).Conclusions There are significant correlations between the serum hs-CRP and induced sputum EOS％,pulmonary function,ACT score in the acute exacerbation bronchial asthma patients.It is found that hs-CRP could be considered as one of the potential marker to evaluate the systemic inflammation level of bronchial asthma.

ner. Furthermore, IL-10 and TGF-β1 showed a synergic effect. Conclusion IL-10 and TGF-β1, the cytokines of regulatory T cells, suppress the formation and bone resorption function of the osteoclasts.

Objective To synthesize 4 kinds of 111 In?TPP cations and evaluate their properties as tumor cationic radiotracers in vivo and in vitro. Methods DO3A?xy?TPP, DO3A?xy?mTPP, DO3A?xy?dmTPP and DO3A?xy?tmTPP were radiolabeled with 111 In;their lipid?water partition coefficients and in vivo and in vitro stability were evaluated. The binding affinities of 4 kinds of 111 In?radiotracers were determined in cell uptake and cell efflux assay using U87MG tumor cells. Biodistribution studies and γ imaging studies were performed using the athymic nude mice bearing U87MG human glioma xenografts to explore the biologi?cal properties of 4 kinds of 111 In?radiotracers. One?way analysis of variance was used. Results The labeling yields of 4 kinds of 111 In?radiotracers were all above 85%, and the radiochemical purity were all greater than 99% after purification. Binding assay in U87MG cells showed that 4 kinds of radiotracers had great binding affinity and cell retention ability, and 111In?DO3A?xy?mTPP had the best binding ratio (1?49%;F=177.8, P<0.05) . Gamma imaging and biodistribution results showed that the U87MG tumors could be clearly visualized by 111In?DO3A?xy?mTPP, 111In?DO3A?xy?dmTPP and 111In?DO3A?xy?tmTPP, and the liver uptake of the 3 tracers was lower than that of 111In?DO3A?xy?TPP. In particular, 111In?DO3A?xy?mTPP had the best tumor/liver ratio (0.13±0.05, 2 h postinjection;F=9.4, P<0?05). Conclusions The tumor?targeted ability of 111In?DO3A?xy?mTPP is better than those of 111In?DO3A?xy?dmTPP, 111In?DO3A?xy?tmTPP and 111In?DO3A?xy?TPP, suggesting that it has the potential to be a promising tumor cationic radiotracer.

Objective To investigate the clinical significance of platelet activation markers CD62p and PAC-1 in patients with hypertension and coronary heart diease.Methods To select patients who were in the Second Affiliated Hospital of Dalian Medical University between January 2012 and September 2012,42 patients with hypertension,46 patients with coronary heart disease.Flow cytometry was used to test the positive percentage of the platelet surface activation markers CD62p and PAC-1 .To observe the difference among hypertension group,coronary heart disease group and health control group;hyper-tension and coronary heart disease group.Results The positive percentage of platelet activation markers CD62p and PAC-1 in hypertension (36.36±9.62,7.18±8.20)%,coronary heart disease group (42.74±14.60,8.81±12.53)% showed sta-tistically significant differences (t=4.150~5.853,P<0.01)compared with healthy control group (26.82±9.13 ,1.09± 1.05)%.The positive percentage of CD62p in coronary heart disease group (42.74±14.60)% was also higher than that of hypertension (36.36±9.62)%,and the difference between them was of statistical significance (t=2.444,P<0.05).Con-clusion The hypertensive patients and coronary heart disease were in pre-thrombotic state,the activation of platelet increase significantly.Molecular markers should be measured in hypertensive patients and coronary heart disease for prevention and treatment of thrombotic disease complication.

Objective To study the changes of six sex hormones corresponding to the follicle growth during the normal menstrual cycle of Chinese women.Methods Thirty Chinese women with regular menstrual period and average age of (28.8±3.2) years were selected for the study by Peking Union Medical College Hospital in September,2010.Growth of follicles was monitored by using transvaginal sonography.Six sex hormones,including follicle-stimulating hormone (FSH),luteinizing hormone (LH),estradiol (E2),progesterone (P),testosterone (T),and prolactin (PRL) were measured by chemoluminescence immunoassay every day during a menstrual cycle.Nonparametric statistical analysis was used.ResultsMenstrual cycle of all the patients was in the range of 25 to 39 d,with mean of (29.5 ± 3.1) d.Length of follicular phase and luteal phase was 15.3 and 14.4 d,respectively.Number of days from antral follicle to emergence of dominant follicle,and from the latter to ovulation,was 6.2 and 8.9 d,respectively.Average diameter of preovulatory follicle was 19.33 mm.Both FSH and LH reached peak on the day before ovulation.P started to increase before ovulation and remained at a high plateau from 6th to 9th day after ovulation.Both PRL and T reached peak after ovulation,near the end of a menstrual cycle.Conclusions A small rise of LH and P emerges just 1 to 2 d before ovulation,indicating the maturing of follicle.PRL and T shows cyclic changes as follicle grows.Therefore,PRL and T levels should be measured in the early follicle phases in the clinical practice so that leading the impact of menstrual cycle minimal.

Objective To explore the effects of Huperzine A on memory in rats with repeated electroconvulsive stimulation. Methods 48 adult male Sprague-Dawley rats were randomly divided into true electroconvulsive stimulation group (E group) and sham electroconvulsive stimulation group (C group). Then both groups were randomized to receive Huperzine A (EH group and CH group) or normal saline (ES group and CS group). There were 12 rats in each subgroup. Huperzine A or normal saline was administered during 1~17 d. During 8~17 d,true or sham electroconvulsive stimulation were administered. On the 18th d, the rats were tested in Morris water maze. Then 6 rats of each group were randomized to be taken for probe tests after 48 h. Memory test indexes include swimming speed, latency, and search time. Results There was no significant difference in the latency between CS group and CH group (P>0.05). The latency was significantly longer in ES group than in CS group (P<0.01), and shorter in EH group than in ES group (P<0.05). There were significant difference in the search time between around the hidden platform and in the opposite area in CS group, CH group and EH group (P<0.05). But there was no difference in ES group (P>0.05). Conclusion Chronic repetitive electroconvulsive stimulation can lead to spatial memory impairment in rats. Huperzine A may attenuate electroconvulsive stimulation induced amnesia.
