Objective To analyze the influence of dexamethasone in the hypotonic-induced volume-sensitive chloride currents in human trabecular meshwork cells,and to investigate the possible mechanism of volume-sensitive chloride channels(VACC)in the glucocorticoid-induced glaucoma(GIG)cases.Methods The human trabecular meshwork cells were seeded in 35 mm diameter plastic petri dishes,so that they could grow in monolayer.The cultured cells were divided into normal cell culture medium group and dexamethasone 1 d,3 d,7 d groups.The chlorine current density values of the cells in four groups were recorded respectively by the whole-cell patch-clamp technique. The differences among groups were compared.Results In normal group,after hypotonic stimulation,under+100 and-100 mV voltage clamp,the outward and inward current density values of the trabecular cells were (19.94±0.87) and (-6.53±0.41)pA/pF.In dexamethasone 1 d,3 d,and 7 d groups,under the same condition,the outward and inward current density values of the trabecular cells were (19.39 ± 1.40)and (-6.42 ± 0.28)pA/pF, (17.97±2.35)and (-5.82±0.94)pA/pF,(17.16±1.16)and (-5.65±0.43)pA/pF.The trabecular cells cultured with dexamethasone for 1 d had lower outward and inward current density values under hypotonic stimulation compared with normal group,but there was no significant difference (P>0.05).The trabecular cells cultured with dexamethasone for 3 d and 7 d,when compared with normal group,had significantly lower outward and inward current density values under hypotonic stimulation (P<0.05 ). Conclusion Dexamethasone could reduce the volume-sensitive chloride current in trabecular meshwork cells,which would affect trabecular meshwork cell volume adjustment.This would possibly cause the increase of the aqueous humor outflow resistance among GIG cases.

Objective To explore the protective effect of a small balloon on bifurcation lesions by applying a single stent treatment of coronary bifurcation lesions strategy. Methods Fifty patients with coronary bifurcation lesions were randomly divided into A group and B group( 25 cases for each group ). Patients in A group were treated with the pre-entry protection branch guide wire to complete the main branch balloon pre-dilation,stenting,while in B group were treated with the set aside the branches of a small balloon. The information of main branch balloon pre-dilation,stenting were recorded. The blood flow slowed down,the incidence of side branch occlusion or stent placement,and the incidence of postoperative 24 h troponin I( cTnI) levels were measured. Results Nine cases(36%)in A group occurred lower branch blood flow,which due to 4 cases(16% )with significantly narrow branch stenting,2 cases(8%)with complete occlusion. There were only 2 cases(8%)with decrease branching blood flow in B group,and the difference was significant(P=0. 041, 0. 022). The cases with higher cTnI after 24 h in A group were 11( 39%),significantly higher in group B (3(12 %);P =0. 027 ). Conclusion Compared with the traditional protection guidewire,the approach of setting aside a small balloon to protect important branch can effectively prevent important branch occlusion, branch involvement due to lower incidence of myocardial infarction.
