Objective:To investigate YKL-40-mediated inflammation in human bronchial epithelial cells and analyzed the soluble factors secreted by bronchial epithelial cells exposed to YKL-40 that were responsible for increasing proliferation and migration of primary normal human bronchial smooth muscle cells (BSMCs).Methods:YKL-40-induced inflammation was assayed in two human bronchial epithelial cells (BEAS-2B cell line and primary human bronchial epithelial cells ,namely HBECs).In addition,we treated BEAS-2B cells and HBECs with YKL-40,and added the conditioned culture media ( YKL-40-BEAS-2B-CM) and ( YKL-40-HBECs-CM) to BSMCs.The proliferation and migration of BSMCs were determined by premixed WST-1 cell proliferation reagent and QCM chemotaxis migration assay ,respectively.Results: Bronchial epithelial cells treated with YKL-40 resulted in a significant increase of IL-8 production,but have no effect about RANTES ,Eotaxin and TNF-α.YKL-40-BEAS-2B-CM and YKL-40-HBECs-CM induced IL-8 was found to further stimulate proliferation and migration of BSMCs ,and the effects were inhibited after neutralizing IL-8.Conclusion:Through investigating the interaction of airway epithelium and smooth muscle ,our findings implicate that YKL-40 may be involved in the inflammation of asthma by induction of IL-8 from epithelium,subsequently contributing to BSMCs proliferation and migration.Moreover, inhibition of IL-8 signaling is a potential therapeutic target for YKL-40-induced inflammation and remodeling of asthma.

Objective To study the role of Cysteine-rich 61 ( Cyr61/CNN1) in repair of combined injury by observing whether exogenous CCN1 promotes the proliferation and migration of radiation-injured L929 cells. Methods A radiation model of L929 cells was induced by ? ray at a dose of 4 Gy. The irradiated L929 cells were cultured in a medium containing 2 ml adenovirus plasmids of CCN1 or RFP at 37 ℃ in an atmosphere containing 5% CO2,which served as a CCN1 group and a RFP group,respectively. Irradiated L929 cells cultured in a blank control medium served as a blank control group. Effects of CCN1 on proliferation and migration of radiation-injured L929 cells were detected by MTT assay,plate colony formation assay,cell cycle analysis,and scratch test of wound healing. Results The proliferation and colony formation rates of L929 cells cultured in a medium containing CCN1 were significantly higher than in RFP and control groups [colony formation rate:( 34. 4 ?3. 6) % vs ( 24. 5 ?2. 9) % and ( 29. 5 ?3. 5) %,P

ObjectiveTo investigate the relationships between traditional Chinese medicine(TCM) syndrome differentiation and serum cystatin C(Cys-C) and homocysteine(Hcy) in patients with chronic heart failure(CHF). Methods 115 cases with CHF admitted into the Department of Cardiology of the First Affiliated Hospital of Zhejiang Chinese Medical University were selected in the CHF group, and 30 cases who had taken health examination in the same period were chosen in the healthy control group. According to the TCM syndrome differentiation, the CHF cases were subdivided into four groups with different types of syndrome: 30 cases of deficiency of both Qi and Yin syndrome, 30 cases of Qi deficiency syndrome and blood stagnation syndrome, 30 cases of heart and kidney Yang deficiency syndrome and 25 casesof flooding due to Yang deficiency syndrome. The serum levels of Cys-C and Hcy in different groups were tested, and the relationships between TCM syndrome differentiation and serum Cys-C and Hcy were analyzed by using Spearman rank correlation analysis.Results The serum levels of Cys-C and Hcy in the patients with CHF were significantly higher than those in the healthy control group〔Cys-C(mg/L):1.24±0.34 vs. 0.77±0.22, Hcy(μmol/L):18.66±4.57 vs. 11.65±3.21,bothP<0.05〕. Compared with the healthy control group, the serum levels of Cys-C and Hcy in the above four groups of different syndromes had a tendency of gradual elevation in the sequence as follows: deficiency of both Qi and Yin, Qi deficiency and blood stagnation, heart and kidney Yang deficiency and flooding due to Yang deficiencygroups〔Cys-C(mg/L):1.02±0.27,1.09±0.31,1.32±0.22, 1.59±0.25; Hcy(μmol/L): 14.94±2.20, 17.66±3.04, 19.79±3.48, 22.96±5.31〕, and the elevation in levels of flooding due to Yang deficiency group was the most prominent compared with that in other groups(P<0.05). The correlation analyses showed that different types of TCM syndrome in patients with CHF were positively correlated with the levels of Cys-C and Hcy(r1=0.73,r2=0.79,bothP<0.05).ConclusionThe changes of serum Cys-C and Hcy levels are consistent with the evolution of regular pattern of TCM syndrome differentiation in patients with CHF, and these two markers can be regarded as the objective indicators of TCM syndrome differentiation of CHF.
