This article presented a series of cases using vascularized interpositional periosteal-connective tissue ( VIP-CT) flap with guide bone regeneration ( GBR) in peri-implant soft and hard tissue reconstuction at the esthet-ic zone of maxillary. Fifteen cases with bone and soft tissue defects underwent VIP-CT flap with GBR in the implant treatment. And the attached gingiva width was evaluated before treatment and six months and eighteen months after the operation. The width of attached gingival of six months and eighteen months after surgery was significantly dif-ferent from the preoperative value (P<0. 05). However, no statistically significant difference could be found at six months and eighteen months postoperative. The application of VIP-CT flap could increase the width of attached gin-giva around implants and the short-term effects were stable and favorable.

Objective To investigate the effects of cell hypoxia on radio-inducible activity of early growth response gene-1 (Egr-1) promoter and its mechanisms. Methods The reporter vector of Egr-1 promoter was constructed by inserting the promoter sequence upstream the lucifearase gene in pGL3, which was then transfected into the lung adenocarcinoma A549 cell by liposome. The luciferase activity and H 2O 2 production were detected in the transfected cells exposed to doses of 2, 4, 6, 8, and 10 Gy radiation combined with the oxygen concentrations of 0.1%, 0.5%, 1%, 2.5%, and 5 %. The changes of luciferase activity in the transfected cells exposed to various concentrations of H 2O 2 were observed. Results The reporter vector of Egr-1 promoter was constructed successfully. The radio-inducible activity of Egr-1 promoter decreased significantly in the transfected cells exposed to oxygen concentration below 2.5% in a concentration-dependent manner, as compared with that in the normal control (P

Euphorbia kansui (EK) is a toxic herbal drug, and often used after vinegar-processing to reduce its toxicity. In present study, a 1H-NMR based metabonomic approach was used to evaluate the detoxification effect of vinegar-processed EK. The water extracts of EK and VEK were administered orally to male SD rats at doses of 9 g x kg(-1) x d(-1) for 1 week, respectively, and one more week observation was further conducted. The control group was orally given with saline. Histopathological studies of liver samples on the 8th and 15th day were conducted, and the metabolites of rat urine and liver were analysed by 1H-NMR. Histopathological studies of liver samples from EK and VEK treated rats showed no negative impacts. In metabonomic analyses of urines, changes of metabolites indicated liver damages, kidney lesions and imbalance of gut microbes in the second week. VEK-treated rats showed a quite lower toxicity compared with EK-treated ones. The present study revealed that the metabonomic approach might be helpful for the evaluation of toxicity of EK and detoxic effect of VEK.
