RESUMO
@#AIM: To observe the effects of Qi Jing Mingmu decoction combined with artificial tears on the clinical results and cell aging of conjunctivochalasis. <p>METHODS: Forty cases(80 eyes)of grade II-Ⅳ CCH with liver-kidney Yin deficiency were randomly divided into two groups: combined treatment group and artificial tears group, which were treated with Qi Jing Mingmu decoction combined with artificial tears and simple artificial tears respectively. The international ocular surface disease index(OSDI), tear break-up time(BUT)and Schirmer Ⅰ test(SⅠt)were observed and the clinical effects were compared after 3mo treatment. For CCH patients with grade III or above, followed up for 3mo or more and willing to operate, the loose conjunctival tissue was removed and the cell aging related β-gal staining was performed on frozen sections. The results were statistically analyzed. <p>RESULTS: The OSDI score(14.53±2.68), BUT 9.25±3.02s and SⅠt(8.95±3.57mm/5min)of combined treatment group were significantly better than those of artificial tears group after 3mo treatment(all <i>P</i><0.05). After drug treatment, 7 cases(7 eyes)in artificial tears group and 4 cases(4 eyes)in combined treatment group of CCH patients were treated by operation. The positive rate of aging cells in combined treatment group was significantly lower than that in artificial tears group(16.00±7.84 <i>vs </i>39.00±14.09, <i>P</i>=0.013).<p>CONCLUSION: Qi Jing Mingmu decoction combined with artificial tears to treat CCH is more effective than simple artificial tears in relieving ocular symptoms, improving tear film and promoting tear secretion. Combined treatment can also reduce the cell aging in CCH, which can be used as a safe and effective treatment method in addition to surgical operation.

RESUMO
Background Bulbar conjunctiva tissue appears to be thinning,elasticity declined,tension reduced and fascia atrophied in conjunctivochalasis.Histopathological examination of conjunctivochalasis shows decrease of elastic fibers and melt of collagen fibers.But there are fewer studies on the ultrastructure of conjunctiva of conjunctivochalasis up to now.Objective This study was to investigate the ultrastructure change of conjunctiva tissue in conjunctivochalasis.Methods Five loose conjunctiva samples of conjunctivochalasis and 5 normal conjunctival tissue samples were collected and ultra-microstructure changes of these samples were observed under the transmission electron microscope.Results The number of fibroblasts in conjunctivochalasis lamina was progressively decreased.The shape of fibroblasts was long and fusiform.Somatic synapse was slim.Nucleus-cytoplasm ratio was increased.Disorder,scattered and broken of the collagen fibril were seen,and some areas were dissolved or lacunae.Normal conjunctival fibroblasts were oval or polygonal,with wieners and long somatic synapse,and intercellular matrix was full of collagen fibril and dense arranged fibers.Fibroblasts in fascia of eonjunctivochalasis were linear,and collagen fibril was seriously defected.Fascia fibroblasts of normal bulbar conjunctiva were spindleshaped and bigger than conjunctivochalasis fibroblasts.There were full of collagen fibrils in intercellular matrix.Conclusions The collagen fibril is decreased and fibroblast cells are degenerated in lamina and fascia of conjunctivochalasis.
