Background Proliferation of the human Tenon capsule fibroblasts(HTFs) is a main cause of failure of filtering surgery.To search the drug of inhibiting the growth of the HTFs is essential for the improvement of successful rate of filtering surgery.Objective The aim of this study was to investigate the inhibitory effect of apigenin on HTFs and its mechanism.Methods Human Tenon capsular tissue was obtained during the strabismus correction surgery.HTFs was primarily cultured using explant method and identified using vimentin by immunochemistry.The 3-5 generation of cells were incubated to 96-well plate.Apigenin of 0,20,40,80,160 μmol/L was added into the medium,respectively,for 24,48,72 hours,and the proliferation of HTFs was detected by sulfonyl chloride (SRB) at the wavelength of 560 nm (A560).Bromodeoxyuridine (BrdU) of 10 μg/L was added to culture the cells for 48 hours to calculate the labeling rate of BrdU.The morphology of the cells was observed using Hoechst 33258 staining,and apoptosis and cells cycle were evaluated by flow cytometry.Results Cultured cells grew well with the positive response for vimentin,showing the green fluorescence in cytoplasm.SRB assay showed that the A560 value was gradually declined with the increase of the dosage of apigenin and prolong of time (Fgroup =480.306,P =0.000 ; Ftime =555.144,P =0.000).The labeling rate after 0,40,80 μmol/L apigenin acted for 48 hours was (87.860 ±0.632)％,(61.520±4.306)％ and (23.480±4.472)％,showing a significant difference among the three groups (F =299.347,P =0.000).The labeling rate of HTFs for BrdU was significantly decreased in the 40 and 80 μmol/L apigenin groups compared with the 0 μmol/L apigenin group (P＜0.05).Hoechse 33258 staining found that the number of the HTFs was gradually decreased and the cell number of karyopyknosis and nuclear deformation was increased with the increase of apigenin dosage.Percentage of cells in G0/G1 phase were raised and that in S and G2/M phase were declined in the higher dosage apigenin group,with a significant difference among the different groups (FG0/G1 =58.621,P=0.000;Fs =32.357,P=0.001 ;FG2/M =83.998,P=0.000).In the 72nd hour after acted by 0,40,80,160 μmol/L apigenin,the apoptosis rate of HTFs was (4.77±0.21) ％,(13.24±1.35)％,(18.33±1.86) ％,(31.58 ± 2.77) ％,respectively,with a statistically significant difference among the four groups (F =204.791,P＜0.05).Conclusions Apigenin restrains the growth of HTFs by evoking G0/G1 cell cycle arrest and inducing apoptosis in a dosage-and time-dependent manner.

Background Macular edema following phacoemulsification with intraocular lens (IOL) implantation is a main factor to influent visual function.The administration of traditional medicine can relieve tissue edema,but its preventive and treatment efficacy on macular edema after phacoemulsification with IOL implantation remaines unclear.Objective This study was to investigate the protective effect of huoxuehuayu decoction on macula after phacoemulsification with IOL implantation.Methods A case-controlled observational study was designed.One hundred and eighty eyes of 150 patients with age-related cataract were randomized into operation group and operation + medicine group.Phacoemulsification with IOL implantation was performed in both groups,but huoxuehuayu decoction was orally administered for 14 days in operation+medicine group.The best corrected visual acuity,inflammatory reaction of the ocular anterior segment,and macular edema were recorded before operation and 1 week,2,4,6,8 and 12 weeks,and the central macular thickness was measured using optical coherence tomography.Results Twelve weeks after surgery,the ratio of visual acuity ≥ 1.0 was in significantly higher in operation+medition group than that of in operation group (x2 =1.066,P＞0.05).One week after surgery,the eyes of the aqueous flare were much nore in the operation group than that of operation+medicine group(x2 =9.341,P＜0.05).The thickness of the central fovea was significantly increased in both groups at 1 week,2,4,6,8 and 12 weeks after surgery,showing significant differences in comparison with preoperation (operation group:P ＜ 0.01 ; operation + medicine group:P ＜0.05).Macular edema occurred in 13 eyes in operation group during the following-up duration,including 11 eyes with thickened fovea and 2 eyes with cystoid macular edema.Maeular edema disappeared in 10 eyes 12 weeks later.In the operation+medition group,3 eyes happened macular edema,including thickened fovea in 2 eye and cystoid macular edema in 1 eye.Four to six weeks after surgery,macular edema disappeared in 3 eyes 12 weeks later.The fovea thickness in the operation+medicine group was statistically significantly lower from 2 through 8 weeks after surgery than that in the operation group(t=2.315,2.323,3.104,2.470,P＜0.05).Conclusions Oral administration of huoxuehuayu decoction is helpful for the restoration of the anterior ocular segment.Huoxuehuayu decoction can protect macula from the edema induced by phacoemulsification.

AIM: To investigate the protective effect of huoxuehuayu decoction on macula after phacoemulsification. Into A, B groups. The 80 eyes of A group were treated by conventional phacoemulsification; the patients (60 eyes) of B group were given huoxuehuayu decoction orally for two courses after phacoemulsification. Best-corrected visual acuity(BCVA), corneal and aqueous conditions ,thickness of macular central fovea and changes of macular retinal tissue in A, B groups were observed before surgery, 1 day; 1 week,2,4,6,8 weeks and 3 months after surgery. Was significantly higher than that of group A. One week after surgery the ratio of mild aqueous flare in group B was significantly lower than that of group A. The thickness of central fixation was significantly increased in both groups 1 week, 2, 4, 6, 8 weeks and 3 months after phacoemulsification; the difference between 2 to 8 weeks after surgery and pre-operation showed statistical significance in both groups. 11 eyes in A group had macular edema during 2 to 6 weeks after surgery, including 9 eyes with fovea thickened and 2 eyes with cystoid macular edema, and seven eyes' edema disappeared in 3 months. 2 eyes in B group had macular edema, including 1 eye fovea thickened and 1 eye cystoid macular edema, during 4 to 6 weeks after surgery, and the two eyes' edema disappeared 3 months after surgery. The fovea thickness in group B during 2 to 8 weeks after surgery was statistically lower than group A. Phacoemulsification.

Osteoarthritis (Osteoarthritis, OA) is a common clinical degenerative joint disease with increased incidence rate in recent years. Animal experiment is one of the important ways to explore pathogenesis and treatment of OA, while induced animal model is the most important part in animal experiment. Intra-articular injection of drugs is a classical method for establishing animal model of OA. Choose of animal should follows the principle of correlation, appropriateness and practicability, injections should perform in accordance with experimental purposes and subject, detections means and evaluation methods also should corresponding to experimental reality. The gold standard of OA animal model and intra-articular injections has not build, need further study.

The effects of injection of adenosine into the renal artery on multi- and single-unit spontaneous discharges of renal afferent nerve fibers were investigated in anesthetized rabbits. The results obtained are as follows: (1) injection of 50, 100, and 200 nmol/kg adenosine into the renal artery increased the renal afferent nerve activity (ARNA) in a dose-dependent manner with unchanged arterial pressure; (2) pretreatment with 8-cyclopenthl-1,3-dipropylxanthine (DPCPX, 160 nmol/kg), an adenosine A1 receptor antagonist, partly abolished the effect of adenosine; and (3) pretreatment with a nitric oxide synthase inhibitor N(omega)-nitro-L-arginine methylester (L-NAME, 0.1 mmol/kg) significantly enhanced the ARNA response to adenosine. The results suggest that injection of adenosine into the renal artery activates ARNA via adenosine receptors in anesthetized rabbits and that nitric oxide may be involved in regulating the activity of renal sensory nerve fibers as an inhibitory neurotransmitter.
