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 observe the clinical efficacy of spleen-invigorating and qi-benefiting pediatric massage (tuina) for treating recurrent respiratory tract infection in children with cerebral palsy due to qi deficiency of spleen and lung. Methods: A total of 70 children with cerebral palsy who suffered from recurrent respiratory tract infection due to qi deficiency of spleen and lung were randomized into an observation group and a control group by the random number table method, with 35 cases in each group. Both groups were treated with conventional rehabilitation training, while the observation group was given additional spleen-invigorating and qi-benefiting pediatric massage, and the control group additionally took oral Yu Ping Feng granule. The clinical efficacy was evaluated by the total effective rate, traditional Chinese medicine (TCM) symptom score, and serum levels of immunoglobulin (Ig) A, IgM and IgG. Results: The difference in total effective rate between the two groups after treatment was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased to varying degrees than those before treatment, and the intra-group differences were statistically significant (all P<0.01); the differences in the scores of various TCM symptoms between the two groups were statistically significant (all P<0.05). After treatment, the levels of IgA, IgM and IgG of the children in both groups increased to varying degrees, and the intra-group differences were statistically significant (all P<0.05). The between-group differences in the IgA, IgM and IgG levels after treatment were statistically significant (all P<0.05). Conclusion: Spleen-invigorating and qi-benefiting pediatric massage can effectively treat recurrent respiratory tract infection due to qi deficiency of spleen and lung in children with cerebral palsy, relieve the clinical symptoms and improve immune function, and thus is worthy of clinical promotion and application.

Background The surgery for femtosecond laser created laser in situ keratomileusis(LASIK)flaps has made great progression recent year,but the postoperative corneal wound healing and regeneration of nerve fibers after surgery are closely concerned.Objective This study was to compare and analyze the clinical outcomes between FEMTO LDV femtosecond laser flap and mechanical microkeratome Hansatome flap in LASIK.Methods A prospective case-controlled study was designed.The serial 38 myopic eyes of 38 patients were included from March through July,2010 in Henan Armed Police Force General Hospital.The patients were randomized into FEMTO LDV femtosecond laser assisted flap group(20 patients/20 eyes)and mechanical microkeratome Hansatome assisted flap group(18 patients/18 eyes)with the matched age,gender and refraction of spherical equivalent.HRT Ⅲ examinations were performed before surgery,1 week,1 month and 3 months after surgery to compare the morphological changes atthe center and margin of the flaps,and evaluate the similarities and differences of cellular morphology after surgery between the two approaches.Written informed consent was obtained from each patient prior to this medical trial.Results The best corrected visual acuity was ≥ 1.0 and the refract diopter was similar in both groups(+0.21 D±0.48 D and-0.04 D±0.54 D)1 month after LASIK.The corneal thickness was insignificant increased in the first week after LASIK,and the density of shallow stromal cells was decreased in 1 week,1 month and 3 months compared with pre-operation in the femtosecond laser assisted flap group(t =-27.99,-25.49,-28.87,P ＜ 0.01).In the Hansatome assisted flap group,significantly thickened corneal epithelium was seen in the first week after LASIK compared before LASIK(56.73 μm±2.47 μm versus 51.16 μm±1.11 μm)(t=9.29,P＜0.05),and the density of shallow stromal cells was decreased in 1 week,1 month and 3 months compared with pre-operation in the Hansatome assisted flap group(t =-17.57,-14.13,-19.63,P =0.00).The density of high reflective interface particles in cornea was lower in 1 week,1 month and 3 months after LASIK in the femtosecond laser assisted flap group than that in the Hansatome assisted flap group,showing significant differences between them(t =-13.505,-11.900,-14.084,P＜0.01).The active stromal cells were seen beneath the interface in both groups in the first week and gradually decreased after that time.Intact corneal nerve fibers were found in the femtosecond laser assisted flap group,but those in the Hansatome assisted flap group were shorter and smaller 3 months after LASIK.At 3 months after surgery,the flap margin showed stromal higher reflection and irregular secondary fibrosis in the femtosecond laser assisted flap group,and in contrast,the flap margin had the appearance of a unclearly identified fibrotic scar in the Hansatome assisted flap group.Conclusions Compared with the LASIK and Hansatome assisted flap,the LASIK with FEMTO LDV flap shows earlier nerve fiber regeneration and greater fibrotic scarring,which imply a good wound healing process in the LASIK with FEMTO LDV flap.
