OBJECTIVETo investigate therapeutic effects of vacuum sealing drainage (VSD) in the treatment of soft tissue defect combined with tendon and bone exposure.
METHODSFrom October 2007 to February 2011, 397 patients (412 feet) with open ankle fracture and dislocation combined with soft tissue defected were treated by VSD. There were 301 males and 96 females with an average age of 36 years (ranging age from 20 to 73 years). According to AO classification, 74 feet were type I, 211 feet were type II, 108 feet were type III and 19 feet were type IV. The mean time from injury to operation was 5.6 h ( 2 to 12 h). The mean treatment time of was 10 months (4 to 19 months).
RESULTSOne hundred and forty-one patients were primarily healed, 97 patients were sutured at stage II. Split-thick skin grafting was performed at stage II was performed in 103 patients; free flap transplantation was performed in 25 patients. Three of the 34 patients with infection were removed steel plate; Eviscerate flap coverage wound was performed in 14 patients caused by the first metatarsal bone exposure; Toe amputation were performed in 22 cases caused by toes necrosis. Tarsometatarasl joints perforators' surgery was performed in 10 patients with forefeet necrosis. Thirty hundred and six patients were followed up from 3 to 20 months (averaged 10 months). The wounds healed well.
CONCLUSIONVSD for soft tissue defects caused by ankle injury is a simple and effective method, but can not replace debridement and transfer flap.

OBJECTIVETo compare the ability of osthole (OST) and genistein (GEN) in enhancing bone peak bone mass of rats to prevent osteoporosis.
METHODSThirty-six female one-month-old SD rats of (125 +/- 3) g body weight were randomly divided into three groups, 12 rats in each group, one group was orally administered osthole at 9 mg x kg(-1) d(-1), one group was given genistein at 10 mg x kg(-1) d(-1) and another was given equal quantity of distilled water as the control. The body weight was monitored weekly and the bone mineral density (BMD) of total body was measured every month. All rats were sacrificed after three months, the femoral bone mineral density, the serum levels of osteocalcin (OC) and anti-tartaric acid phosphatase 5b (TRACP 5b) were measured by Elisa. The bone microarchitectures were analyzed with micro-CT and the bone biomechanics properties were tested with universal material machine.
RESULTSNo significant differences were observed between O-treated or GEN group and the control for the food-intake and body weight during three months. However, the rats treated with OST had significant higher BMD for both total body and femur than the control and GEN group. The O-treated rats also had higher level of serum OC and lower level of TRACP 5b. Besides, they owned bigger bone volume/tissue volume, trabecular thickness, trabecular number but smaller trabecular spacing. In the three point bending tests of femurs,they were found to have larger maximum load, the young's modulus and structural model index (SMI).
CONCLUSIONOrally administered osthole could efficiently increase the peak bone mass of rats,which provide new ideas for preventing osteoporosis.

Objective To explore immunotherapy effective combined with active immunotherapy in different time according rats bearing-tumor after paclitaxel and carboplatin chemotherapy, and to identify the optimization time and strategy of vaccine and seek rational chemo-immunotherapy strategies in ovarian cancer treatment. Methods The dynamic immunocytes number and function in established tumor treated with paclitaxel and carboplatin chemotherapy were investigated. The changes of established tumor volume and immune function of different groups were observed according to combining different time after chemotherapy and vaccine. Results Lymphopenia was observed and the number of lymphocyte subset decreased remarkably on the 6th day, but all cells were found almost recovered on 15th day after chemotherapy. There is the process of immune-enhancing from post-chemotherapy 6 day to 10 day and reversal of immune suppression temporary. The combination post-chemotherapy 6 day with CTL caused a significantly delayed tumor growth in both tumor models and induced significant the proliferation of T lymphocyte by [H] 3 releasing. The number of CD8+T cell is the highest, but the expression of Tr cell was lowest in the group of post-chemotherapy 6 day with CTL. Furthermore, the ability of CD8+T secretion IFN-γ is the most in the post-chemotherapy 6 day with immunotherapy groups. Conclusion Combinational paclitaxel and carboplatin chemotherapy has synergistic effects with active immunotherapy boosting against tumor during window periods, where 6 days after chemotherapy with the most decreased number of lymphocytes in the animal periphery might represent the optimal checkpoint for the immune therapy against tumors. Therefore, monitoring the immune status of tumor patients might become one of the important prerequisites for the effective immune therapy when designing the comprehensive therapeutic strategies.

Objective: To investigate the effects of Yiguanjian Decoction, a compound traditional Chinese herbal medicine, on collagen metabolism of hepatic tissues in rats with carbon tetrachloride (CCl(4))-induced liver fibrosis. Methods: Liver fibrosis was induced in rats by intraperitoneal injection of 50% CCl(4)-olive oil solution at a dose of 1 mL/kg body weight, twice per week for 9 consecutive weeks. Six rats were sacrificed for dynamic observation at the end of the 3rd and 6th week respectively, and the other rats were divided into 9-week untreated group and Yiguanjian Decoction group which was given Yiguanjian Decoction intragastrically in the subsequent 3-week modeling period. Another 6 rats were used as normal group. Rats in the normal group and 9-week untreated group were treated with distilled water. At the end of the 9th week, all rats were sacrificed, and their blood serum and liver tissue were collected for measuring hepatic histology and expressions of α-smooth muscle actin (α-SMA), tissue inhibitor of metalloproteinase (TIMP)-1, TIMP-2, matrix metalloproteinase (MMP)-13, MMP-14, collagen type I (Col I), and activities of MMP-2 and -9. Results: Compared with the normal group, collagen fiber deposition, expressions of α-SMA, Col I, TIMP-1, TIMP-2, MMP-13 and MMP-14 and activities of MMP-2 and -9 in the liver tissues gradually increased in the untreated group (P<0.05, P<0.01). These changes were significantly suppressed by Yiguanjian Decoction. Conclusion: Yiguanjian Decoction exerts inhibition on formation of CCl(4)-induced cirrhosis in rats. The therapeutic mechanism may be related to inhibiting hepatic stellate cell activation, collagen secretion, and promoting collagen fiber degradation.
