BACKGROUND:Medical glue as a biological hemostatic material shows a good diffusivity in body fluids and blood, and has a rapid polymerization reaction, which plays an ideal hemostatic effect and promotes wound healing. OBJECTIVE:To investigate the clinical value of medical glue as a hemostatic material in the open wound of the frontal plane in children. METHODS:Totaly 1 218 children with open wounds of the frontal plane treated with medical glue were enroled as observation group, and another 600 children with open wounds of the frontal plane treated with silk sutures as control group. Wound healing time, postoperative wound bleeding, suture reaction, pigmentation and scar hyperplasia were compared between the two groups. RESULTS AND CONCLUSION:Compared with the control group, the operative time, blood loss and wound healing time were al less in the observation group (P < 0.05), and the effective bleeding rate was higher in theobservation group (P < 0.05). Stage I wound healing occurred in 1 215 cases of the observation group, and 586 cases of the control group. At the end of 12-month folow-up, healed scar formed with no knot scar and needle scar, the skin color was similar and cosmetic results were good in the observation group; in the control group, there were more obvious scars, visible knot and needle scars, and erythema, induration and hypertrophic scars were found around the most wounds. The medical glue for open wounds of the frontal plane in children has good biocompatibility and cosmetic results, which is safe and convenient in clinical use.

Objective To investigate the effect of fosinopril on the expression of transforming growth factor (TGF)-activated kinase 1 (TAK-1) in the kidney of rats with unilateral ureteral obstruction (UUO),and its protective effect on renal interstitial fibrosis (RIF).Methods UUO model was induced by ligating the left ureter in rats.A total of 72 male Sprague-Wistar rats were randomly divided into 3 groups:sham-operated group (n=24),UUO model group (n=24) and UUO+fosinopril group (n=24).The rats were treated with 10 mg/(kg?d) by gastric gavage in the fosinopril treated group from 2 d after the operation,and the rats were treated with the identical dose of normal saline in the other 2 groups.Eight rats of each group were sacrificed at 7,14 and 21 d after UUO.Pathological changes of the renal tissue were observed by HE and Masson staining,and the mRNA and protein expression of TAK1 was detected by in situ hybridization,real-time PCR and Western blot analysis.Results The renal interstitial damage index of UUO group was increased compared with that of the sham-operation group (P

OBJECTIVETo investigate the effects of fushenkeli on the expression of TAK1 in the proliferation of the renal tubular epithelial cells induced by TGF-beta1 and its possible mechanism.

METHODHuman renal tubular epithelial (HK-2) cells were divided into five groups:blank control group, TGF-beta1 group (5 microg x L(-1)), intervention group 1 (5 microg x L(-1) of TGF-beta1 + 100 mg x L(-1) of fushenkeli), intervention group 2 (5 microg x L(-1) of TGF-beta1 + 500 mg x L(-1) of fushenkeli) and intervention group 3 (5 microg x L(-1) of TGF-beta1 + 1 g x L(-1) of fushenkeli). HK-2 proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay. Type IV collagen in the supernatants of the cultured HK-2 was detected by ELISA at 12, 24, 48 hours respectively. The protein and mRNA expressions of TAK1 was measured by Western blot and real-time quantitative PCR.

RESULT1) The cell proliferation and the expression of type IV collagen were increased compared with the control group (P<0.05, P<0.01), but they were decreased in intervention group. 2) The expressions of protein and mRNA of TAK1 in TGF-beta1 group were upregulating significantly compared with control group (P<0.01), but they were downregulating in intervention group, especially in intervention group 3.

CONCLUSIONFushenkeli could inhibits TAK1 expression induced by TGF-beta1 in the proliferation of HK-2 cell.
