AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

BACKGROUND:Previous studies have shown that continuous administration of 1×107 of bone marrow mesenchymal stem cel s can induce immune tolerance in rats undergoing kidney transplantation, but it is not yet found clinical y that curcumin exerts an on immunomodulatory effect on kidney transplantation.
OBJECTIVE:To investigate the effects of different concentrations of curcumin on bone marrow mesenchymal stem cel s-induced immune tolerance in rats after kidney transplantation.
METHODS:Rat model of kidney transplantation was made, and rat models were randomly divided into four groups:transplantation group with no treatment;bone marrow mesenchymal stem cel s group (cel group) injected with 1×107/kg bone marrow mesenchymal stem cel s via the left iliac vein (before peritoneal suture) and tail vein (from the 2nd day) for 10 days;bone marrow mesenchymal stem cel s+low/high dosage of curcumin groups (low/high dosage curcumin groups) injected intragastrical y with 2 or 10 mg/kg curcumin combined with injection of bone marrow mesenchymal stem cel s for 10 days. Transforming growth factor-β1 protein expression in the kidney tissues was examined by immunohistochemical staining. The concentrations of interleukin-2 and interleukin-6 in serum were detected by ELISA assay.
RESULTS AND CONCLUSION:After kidney transplantation, the protein expression of transforming growth factor-β1 in renal tubular epithelial cel s and renal interstitial cel s as wel as the concentrations of interleukin-2and interleukin-6 in serum were significantly higher in the transplantation group than the other groups (P<0.05). Compared with the cel transplantation group, the protein expression of transforming growth factor-β1 as wel as the concentrations of interleukin-2 and interleukin-6 reduced significantly in the low/high dosage curcumin groups (P<0.05). These findings indicate that simultaneous administration of curcumin and bone marrow mesenchymal stem cel s can effectively inhibit immune rejection reaction and improve renal function in rats after kidney transplantation.
