Object To investigate the therapeutic effects and mechanism of traditional Chinese compound decoction of Radix Curcumae (RC), Rhizoma Sparganii (RS), and Rhizoma Zedoariae (RZ) (DRRR) on liver fibrosis in rats induced by carbon tetrachloride (CCl 4). Methods Fifty Wistar rats were randomly divided into four groups: group A was healthy control (n=8), group B was model rats of liver fibrosis induced by CCl 4 (n=14), group C and D were treated with DRRR after the liver fibrosis in rats induced by CCl 4 four weeks later (n=14). B, C, and D groups were injected subcutaneously with CCl 4; C and D groups were administrated with DRRR 0.6 and 1.2 g/100 g, once per day. After administration of DRRR four weeks all rats were sacrificed, their blood and liver were harvested for further examination. The effect of DRRR was explored by the expressions and sites of transforming growth factor-beta 1 (TGF-? 1), Smad3 and Smad7 in liver tissues by immunohistochemical staining. The liver function, serum hyaluronic acid (HA), and liver histopathology were also examined by biochemsitry, RIA, HE, and Van Gieson stainings respectively. Results To compare with model group, in rats that received DRRR, the expressions of TGF-? 1 and Smad3 were significantly decreased, while the expression of Smad7 was obviously increased in the livers (P

Objective To summerize clinical application of the trifoliated flap from the dorsal foot. Methods The flaps,which were made of the first dorsal metatarsal flap, medial foot flap and lateral foot flap,were designed on the basis of the anatomy of flap whose common pedicle was anterior tibial artery or dorsal foot artery and whose other branches was medial tarsal artery or medial anterior, melleolar artery and lateral tarsal artery respectively,the single flaps were harvested to repair multi-finger skin defect.The flaps from both feet were repaired digit degloving injuries. Results Thirty-one patients were treated by trifoliated flap from the dorsal foot.29 of 31 flaps survived completely.Two flaps in patient necrosised.One flap in two patients necrosised. Conclusion The trifoliated flap from the dorsal foot is a good procedure for coverage problems in multiple-finger avulsion and digit degloving in juries.

[Objective]To inrestigate the clinical outcomes of using bilateral tibial flap of the second toe nail flap combined with the fibulal flap of the big toe to repair the multi-finger degloving injury.[Method]A variety of different methods were used to repair the multi-finger degloving injury,six fingers in 3 cases were repaired by partial bilateral wrap-around flaps combined with the tibial flap of the second toe.Sixteen fingers in 8 cases were repaired by bilateral second toe nail flap combined with the fibulal flap of the big toe.Six fingers in 2 cases were repaired by bilateral second toenail flap,the fibulal flap of the big toe and the digital arterial island flap.Three fingers in l case were repaired by bilateral second toe nail flap combined with the fibulal flap of the big toe and the the lateral flap of dorsum of foot.Six fingers in 3 cases were repaired by bilateral second toe nail flap and the fibulal flap of the big toe and bilateral dorsum flap of foot.Four fingers in 1 case were repaired by partial bilateral wrap-around flaps and the tibial flap of the second toe and the anterolateral thigh flap.Six fingers in 3 cases were repaired by bilateral second toe nail flap combined with the fibulal flap of the big toe,and bilateral dorsum flap of foot and bilateral anterolateral thigh flap.[Result]Ninety-seven flaps of 98 flaps of 47 fingers in 21 cases were suvived well,with 1 flap developed necrosis.The follow-up duration ranged from 6 months to 9 years in 17 cases (37 fingers).In addition to the activities of DIP limited,the other interphalangeal joint activities were nearly normal.All of the fingernail grew well.Two point discrimination of the fingers was between 5mm and 11 mm.The donor site was hardly affected.[Conclusion]It is a better method using the big toe flap combined with the second toe flap to repair the the multi-finger degloving injury at one stage.

Objective To investigate the effect and its mechanism of “JinSanE” on liver fibrosis induced by carbon tetrachloride (CCl4) in rats. Methods Thirty-six Wistar rats were divided into three groups: healthy controls, CCl4 induced cirrhotic rats, and CCl4 induced cirrhotic rats treated with “JinSanE”, which was begun at the fourth week after exposure to CCl4. “JinSanE” was given once a day. Rats were killed after the administration of “JinSanE” for 4 weeks. The anti-fibrosis effect was determined by the expressions of connective tissue growth factor (CTGF) and transforming growth factor-? 1 (TGF-? 1) in liver tissue. The CTGF and TGF-? 1 mRNA expressions were detected by RT-PCR, CTGF and TGF-? 1 were assessed after immunohistochemistry staining. The serum level of hyaluronic acid (HA) was determined by RIA, and the liver histopathology was observed with light and electronic microscopy. Results Compared with the CCl4 induced cirrhotic rats, the expressions of TGF-? 1 and CTGF were decreased in the liver of the rats which were given “JinSanE” (P
