OBJECTIVETo explore effects and action mechanism of warm moxibustion on regulation of blood lipids and anti-atherosclerosis.

METHODSForty-one male Japanese big-ear white rabbits were randomly divided into a blank group (10 rabbits), a model group (10 rabbits), a moxibustion group (10 rabbits) and a medication group (11 rabbits). Normal diet was applied in the blank group while high-cholesterol diet combined with injection of bovine serum albumin were applied in the rest groups to establish rabbit model of atherosclerosis. After establishment, the model group was not intervened and warm moxibustion was applied in the moxibustion group at "Zusan-li" (ST 36) and "Shenque" (CV 8), 10 min per acupoint per day for continuous 4 weeks. The medication group was treated with intragastric administration of lovastatin capsule (3.6 mg/kg) for continuous 4 weeks. The level of blood lipids, such as total cholesterol (TC), triglyceride (TG), and content of CD40 ligand (CD40L), soluble CD40 ligand (sCD40L) and expression of nuclear factor NF-kappaB were tested after 4 weeks.

RESULTSCompared with the model group, the moxibustion group and medication group could effectively reduce the contents of TC and low density lipoprotein (all P < 0.05), lower the level of sCD40L [(8.310 +/- 1.221) ng/mL in the model group, (7.097 +/- 0.846) ng/mL in the moxibustion group and (7.354 +/- 0.631) ng/mL in the medication group], reduce expression of CD40L [(0.235 +/- 0.179) mm2 in the model group, (0.072 +/- 0.079) mm2 in the moxibustion group and (0.039 +/- 0.015) mm2 in the medication group] and NF-kappaB [(0.145 +/- 0.052)mm2 in the model group, (0.052 +/- 0.012) mm2 in the moxibustion group and (0.036 +/- 0.013) mm2 in the medication group], indicating the significant difference (P < 0.05, P < 0.001). There was no statistical difference between the moxibustion group and medication group (all P > 0.05).

CONCLUSIONThe warm moxibustion has great effect on regulation of blood lipids and anti-atherosclerosis, in which lowering expression of CD40-CD40L could be one of possible mechanisms to take effect of anti-atherosclerosis.

Background Both functional and morphological changes in amblyopic development are known to occur at various levels in the central visual pathway.However,whether the retina is involved or not during amblyopic progression remains controversial.Objective This study was designed to compare the thicknesses of the fovea and retinal nerve fiber layer (RNFL) of the normal fellow eye of amblyopic eye using optical coherence tomography (OCT) in children with myopic anisometropia.Methods Twenty-two patients with unilateral myopic anisometropic amblyopia were included as the anisometropia amblyopia group.Ten unilateral myopic anisometropic amblyopia subjects received treatment and recovered were used as the amblyopic cure group,and 11 individuals with simple myopic anisometropia without amblyopia were enrolled as the control group.OCT was performed on both eyes of all the subjects with informed consent.Fovea retinal thickness and RNFL thickness from the superior,inferior,nasal and temporal quadrants in the peripapillary region were evaluated.The measurement parameters were bilaterally compared in all the individuals by paired t test.The multiple regression model was used to analyze the correlation of retinal thickness with amblyopia patients.This study was approved by the Ethic Committee of this hospital.Written informed consent was obtain from each subject prior to the eye examination.Results Fovea retinal thickness increased in the amblyopic eyes compared with the fellow eyes,showing a statistically significant difference between them (P =0.001).However,no significant differences were found in the fovea retinal thickness between both eyes in the amblyopic cure group and simple myopic anisometropia without amblyopia group (P =0.778,0.943).Among the anisometropia amblyopia group,amblyopia cure group and simple myopic anisometropia without amblyopia group,the RNFL thicknesses of the temporal quadrant was significantly thicker in the higher myopic lateral eyes than those of the fellow eyes (P＜0.001,P =0.003,P =0.046).However,the differences in the superior,inferior,nasal and the average RNFL thickness were not statistically significant between the two eyes (P＞0.05).A negative correlation was found between the inferior retinal thickness with age (r=-0.559,P=0.016).Conclusions The fovea may be affected in unilateral myopic anisometropic amblyopia.There is no significant difference in the RNFL thickness between simple myopic eye and unilateral myopic anisometropia amblyopic eye.Improvement in amblyopia is coming along with the reduction of the thickness of the fovea.

Background Studies demonstrated that human amniotic epithelial cells (AECs) have some characteristics of embryonic stem cells and they were used to re-establish the surface of eyes. Human AECs may serve as new seed cells in tissue engineering for corneal epithelium reconstitution in the future. Objective The present study was to investigate the application value of human amniotic epithelium cells transfected by lentiviral vectormediated enhanced green fluorescent protein (EGFP) gene as new seed cell source for engineering the corneal surfacelayer. Methods Lentiviral vector carrying the objective gene EGFP was transfected into human amniotic epithelial cells (pLenti6/V5-DEST),and the transient expression of the transgene in the human amniotic epithelial cells was observed under the fluorescence microscope. Flow cytometry was used to detect the positive expression rates of EGFP in transfected cells. The transfected human amniotic epithelial cells were seeded onto the fresh corneal stromal surface of New Zealand white rabbit and cultured in vitro. The stem cell deficiency ( SCD ) models were established by cutting off the limbus of cornea in 20 eyes of New Zealand white rabbits, and the model rabbits were then divided into 2 groups randomly. The transplanted grafts carrying the pLenti6/V5-DEST-EGFP gene-transferred human amniotic epithelium cells were regarded as the pLenti6/V5-DEST-EGFP group, and the corneal stroma graft without any epithelial cell served as the control group. The opacity of stroma and corneal conjunctivalization and vascularization were observed daily. The rabbits' eyes were extracted one month after operation. The expression of EGFP in the cornea was detected under the fluorescence microscope, and the expression of CK8, CK18 and CK12 in cornea was detected by immunohistochemical staining. Results The shape of the transferred human amniotic epithelial cells resembled normal human amniotic epithelial cells. 48 hours after the transient transfection of EGFP presented with the highest expression level throughout the observation duration, with a positive expression rate of EGFP of 61.5% ,showing significant differences in comparison with that of 12 ( 5.24% ) , 24 ( 38.27% ) or 96 ( 39. 10% ) hours ( P ＜0. 05) post-transfection; but no obvious difference was found in the positive rate of transiently transfected EGFP between 48 hours and 72 hours ( 58.36% ) ( P＞0. 05 ). Six cornea grafts were clear in 1 month and two corneas were rejected during the observation period in the pLenti6/V5-DEST-EGFP group. A few new blood vessels were seen around the graft. Ten corneas of the control group became opaque and cloudy with new blood vessels growth around the grafts. Imunohistochemistry revealed the positive expressions of CK8, CK1 8 and CK12 in the corneal epithelial layer in the pLenti6/V5-DEST-EGFP group. However,the expression of CK12 was absent in the control group. Conclusion Human amniotic epithelium cells transfected with the pLenti6/V5-DEST-EGFP gene is a new and ideal feed cell type to reconstruct the corneal surface layer. Lentivirus is a relatively safe gene transfection vector.
