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.

ObjectiveTo discuss the effect of neonatal behavioral neurological assessment (NBNA) and developmental screening test (DST) on newborns with hypoxic ischemic encephalopathy (HIE).

AIM: To observe the effect of Ahmed glaucoma valve implantation intravitreal bevacizumab in the treatment of neovascular glaucoma ( NVG) .
METHODS:Twenty-two cases (22 eyes) who presented with NVG were first treated with intravitreal bevacizumab 0. 1mL ( 2. 5mg ), then with Ahmed glaucoma valve implantation after regression of iris neovessels. Cases were followed - up for 6 - 36 ( mean 24 ) mo with observation on visual acuity, IOP control, regression of iris neovessels, and complications during or after surgery.
RESULTS: Iris neovessels was regressed in different degree after injection within 1wk in 22 eyes. At final follow-up, the IOP of 18 eyes were all less than 21mmHg without any drugs and of 3 eyes with 1-3 kinds of anti-glaucoma drugs after combined Ahmed glaucoma valve implantation. The IOP of one eye was controlled after cryotherapy. The mean IOP dropped from 45. 36 ±8.13mmHg preoperatively to 15. 59 ± 3. 21mmHg postoperatively. IOP reduction was statistically significance between preoperative and postoperative ( P<0. 05) at final follow-up. Visual acuity was improved in 9 eyes (41%) and was no changed in 13 eyes. No serious complications were observed during or after intravitreous bevacizumab injection and Ahmed glaucoma valve implantation.
CONCLUSION: Ahmed glaucoma valve implantation and intravitreal bevacizumab in the treatment of NVG is useful and safe. It improves the success rate of surgery and preserves visual function, furthermore its complications are less.

Objective To observe the different effects of iodine excess on inducing two strain mice thyroiditis. Methods NOD and Balb/c mice, each having 14 mice, were divided into NaI and control group. The mice were given 0.05% NaI water for 8 weeks in NaI group. RIA and ELISA were used respectively to detect TT4, TgAb, TPOAb and TSH level in serum. Morphology changes of thyroid and apoptosis of thyrocytes stained by immunohistochemistry were observed under light microscope. Lymphocytic proliferation of cervical lymph node and spleen to responding to Tg were detected by MTr method. Results After intake of iodine water for 8 weeks, NOD and Balb/c mice showed relative quality of thyroid in Nal group[(104.83±14.52), (155.79±20.77)mg/kg]obviously increased compared with control group[(71.80±20.42), (105.15±21.98)mg/kg, t values:-3.293,-4.429, all P< 0.01)], enlarged follicular lumen with colloid accumulation were observed in thyroid. Serum level of TT4 in Nal group [(29.52±4.42), (19.53± 2.35)nmol/L]to control group[33.40±5.38), (23.47±6.22)nmol/L]of NOD and Balb/c mice showed a decreasing tendency(t values: 1.374,1.567, all P > 0.05). TSH of Nal group showed an increasing tendency in Balb/c mice[(4.14±1.71)μg/L, compared with control [(3.55±1.41)μg/L, t values:-0.705, P > 0.05]and obviously increased in NOD mice [(6.98±0.66)μg/L, compared with control[(555±056)μg/L, t values:-3.562, P< 0.01], but no change of TgAb and TPOAb level in Nal group(1281,1364 cpm, 2.50×103, 0.14×103U/L were observed, compared with control(1297,1220 cpm, 3.17×103,0.03×103 U/L; Zvalues:-0.081,-0.703, -0.244,-1.293, all P > 0.05). In NOD mice NaI group, apoptosis of thyrocytes was more intense than Balb/c mice, obvious infiltration of lymphoeytes, disorganization and focus fibrosis was seen in thyroid. The cell amount of NaI group increased in NOD mice lymph node and spleen cells[(1.100±0.014), (1.076±0.033)]were more than that in the control group [(0.993±0.011), (1.005±0.003), t value:-11.672,-4.314, P < 0.01). Conclusions Iodine leads to enlargement of thyroid and malfunction of thyroid in Balb/c mice. Besides, NOD mice have generate inflammatory reaction in thyroid and produced sensitized lymphocytes to Tg. Iodine excess can induce NOD mice to occur autoimmune thyroiditis.

OBJECTIVETo investigate the anti-proliferation and anti-migration dual effects of aloe-emodin on KB cells and its mechanisms.

METHODSKB cells were treated with 2.5, 5, 10, 20 and 40 micromol/L aloe-emodin. Crystal violet assay was used to determine the long-term growth inhibition of aloe-emodin on human oral cancer KB cells. Scratch wound-healing motility assay was used to measure the antimigration effect The protein kinase C alpha and c-myc expression changes in protein levels were detected by Western blotting.

RESULTSA durable cell growth inhibitory effect of aloe-emodin on KB cells was found. Treatment of aloe-emodin resulted in the inhibition of cell migration. The protein kinase C alpha and c-myc in protein levels were decreased upon treatment with aloe-emodin compared with controls.

CONCLUSIONSThe anti-proliferation and anti-migration effects of aloe-emodin on KB cells are associated with the suppression of protein kinase C pathway.

Objective To investigate the clinicopathologic relationship between serum platelet derived growth factor-BB(PDGF-BB)and IgA nephropathy in children.Methods The level of serum PDGF-BB was detected by double antibody enzyme linked immunosorbent assay(ELISA) in 15 cases healthy children and 30 cases IgA nephropathy.According to patholgical degree constituted by WHO in 1982,the IgA nephropathy group divided into 5 degrees:Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ(Ⅰ,Ⅱ were light patholgic change group;Ⅲ,Ⅳ were moderate patholgic change group;Ⅴ was severe patholgic change group).The serum PDGF-BB in IgA nephropathy group and none-IgA nephropathy group,and in different renal pathology type IgA nephropathy group were analyzed.Data were analyzed by using SAS 6.12 software.Results The level of serum PDGF-BB were(247.35?55.79) ng/L in control group and(869.16?200.73) ng/L in IgA nephropathy group.It was higher in IgA nephropathy group than in control group,the difference was significant(P

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.
