Traditional Chinese medicine (TCM) exhibits a broad range of effects on biological activity that is probably due to interactions of complex chemical constituents with multiple targets in the body. Understanding the active chemical constituents in TCM is very important in providing rationales for the clinical usage of TCM. The zebrafish (Danio rerio) has recently become a popular model in the field of drug screening, specifically emerging as an important vertebrate model for in vivo high-content drug screening of multiple efficacy parameters and whole-organism toxicity. The authors also discussed the advantages of the zebrafish model for evaluating drug metabolism. Zebrafish usage in TCM screening should be a viable approach that helps identify active chemical markers, biological pathways and mechanistic actions of TCM.

Glycogen synthase kinase 3β (GSK3 β) is a conserved cytoplasmic serine/threonine protein kinase.It can not only negatively regulate the classical Wnt and Akt signal pathways which are associated with leukemia,but also positively regulate the NF-κB,non-classical Wnt and lysosomal apoptosis signal pathways,thereby regulating the proliferation,differentiation and apoptosis of leukemia cells.At present,a variety of GSK.3 β inhibitors and activators have been reported in the researches of leukemia,which play important roles in reducing the adverse reactions of chemotherapy,reversing multidrug resistance and enhancing killing effect to leukemia cells.GSK3β is expected to become a target of leukemia molecular targeted therapy.

Objective To study the classification, management and outcome of the fracture of ulna coronoid process. Methods Retrospective analysis was carried out in 31 patients with fracture of ulna coronoid process. There were 19 males and 12 females with an average age of 29.8 years old (range, 18-52 years old). The fractures of ulna coronoid process were classified into 4 major groups based on the condition of the injury of ulna coronoid process, the anterior bundle of the ulnar collateral ligaments(UCL) and the elbow stability. The fracture of coronoid process within half of the height was defined as type Ⅰ. The half of coronoid process fracture with the injury of UCL was defined as type Ⅱ. The base of coronoid process fracture with the dislocation of elbow joint was defined as type Ⅲ, sometimes with the injury of UCL. The severe comminute fracture of coronoid process with elbow instability was defined as type Ⅳ. There were 11 cases in typeⅠ, 9 typeⅡ, 6 type Ⅲ and 5 type Ⅳ in our group. According to the type of injury we choose correlative treatment. Results The follow-up was 18-72 months(average 28.6 months). All the patients got fracture union, and without inflammation, neural injuries and elbow instability. 1 type Ⅲ and 2 type Ⅳ had traumatic osteoarthritis, and 2 type Ⅲ and 2 type Ⅳ occurred heterotopic ossification. There was a statistical significance when the motion range of two-side joints was compared in type Ⅳ. Conclusion We choose conservative treatment in the fracture of typeⅠ. But if the piece of bone affected motion of elbow joint, we can choose operative treatment, and elbow stability is not affected. The fracture of type Ⅱ and type Ⅲ with elbow instability should be reduced internal fixation and the ligament must be repaired or reconstructed. In cases of type Ⅳ, bone reconstruction is necessary to recover of elbow stability. Proper post-operative rehabilitation can decrease the rate of traumatic osteoarthritis.

0. 05). Conclusions The kidney transplantation without prior dialysis offered comparable patient/graft survival to kidney transplantation with prior dialysis and avoided the dialysis complications and sensitization of transfusion, while reduced the risk of acute rejection. Therefore, uremic patients may be considered to receive the kidney transplantation without prior dialysis in clinic.

[Objective] To evalvate the influence of total knee replacement(TKR)on the lipid peroxdation in erythrocytes,and the prophylactic treatment of Vitamin E and fructose 1,6-diphosphate(FDP)on it.[Method]Totally 60 patients of knee osteoarthritis were divided into control group,Vitamin E group,Fructose 1,6-diphosphate(FDP)group and Vitamin E added FDP group.Blood samples were taken for biochemical determination of MDA and Cu-Zn-SOD before and after the operation at 1,3,5 and 7 days.[Result]MDA level in erythrocytes increased singnificantly after TKR compared with that before operation(P

Objective To testify the possibility that two-hour concentration (C_2) substituting for the target concentration (C_0) is used to be a monitoring tool for CsA. Method The whole blood concentrations of CsA having taken orally in 17 renal transplant patients were measured by FPIA. The data of concentration-time was processed by 3P87 pharmacokinetic program. Results The correlation between C_2 values and AUC_ 0-4 , or AUC_ 0-12 was both more excellent than C_0( P

Objective To evalvate the influence of elbow joint stability following ulna coronoid process fractures. Methods Three cadaveric upper extremities were used. The height, width, thickness, diameter and opening angle of ulna coronoid process were measured in six arms, while the coronoid process fragments at the level of 2 mm, quarter, half, three quarter and whole height were resected consecutively, the changes of the range of the elbow joint movement were recorded. Another sixteen specimens were divided into two groups: the anterior bundle of the ulnar collateral ligaments (UCL) in one group was unrepaired; While the other repaired, then the angle of cubitus valgus between two groups was compared. Results If the osteotomy bone was within quarter of ulna coronoid process, the elbow joint function was good. However, in cases of osteotomy on half of coronoid process, the elbow extension function was limited and the elbow became unstable. After reduction with internal fixation, the angle of cubitus valgus was greater in the second group, and the difference of elbow joint in flexion 0?, 30?, 60?, 90? and 120? had statistical significance(P

Objective To summarize the experiences of kidney retransplantation from 1978 to Dec. 2002.Methods The clinical data of 86 cases subject to first renal transplantation and 86 cases to second renal transplantation were retrospectively analyzed. The main causes of failure of the first renal transplantation were CAN, while those of the second renal transplantation were HAR, and other complications such as AR, graft rupture and serious graft T.B. PRA or CDC in 31 cases was positive before retransplantation. The clinical data such as antibody-inducing therapy, the protocols of immunosuppression and the survival rates of patients and grafts in these patients were analyzed.Results Survival rates at 1, 3, 5 year of the patient/graft of retransplantation group were 84.8 %/61.6 %, 79.1 %/45.3 % and 58.1 %/41.9 % respectively, while those at 1, 3, 5 years of the patient/graft with the first renal transplantation were 89.5 %/79.1 %, 81.4 %/74.4 % and 67.4 %/58.1 % respectively. No significant difference in the patient survival rates and graft survival rates was observed (P

Objective To investigate the risk factors for delayed graft function (DGF) under-(going) cadaver renal transplantation.Methods Twenty-four relative variables were analyzed by SPSS11.0 statistical software. Using chi-square analysis method, the influence of these variables on DGF was retrospectively studied. Logistic regression analysis was done to assess and rank the relative risk of potential variables.Results The overall incidence of DGF was 5.01 %. Chi-square analysis (revealed) that the risk factors for DGF were identified as: cold ischaemia time, warm ischaemia time, recipient hypovolaemia, number of previous transplants, allosensitisation of the recipient, ATN, (accelerated) rejection, cyclosporine nephrotoxicity, ureteral leakage obstruction. Logistic multivariate analysis showed that there were 8 risk factors contributing to DGF.Conclusion DGF is a common (allograft) complication in the immediate posttransplant. There are many risk factors contributing to this condition. The basic change is ischemia-reperfusion injury. It is very important to comprehend the risk (factors) thoroughly in order to prevent them effectively.

Objective To investigate the technical features, postoperative complication and therapeutic regimen of immunosuppressant in pediatric and adolescent renal transplantation. Methods From February 1998 to December 2004, clinical data of 46 pediatric and adolescent patients who underwent renal transplantation were retrospectively analyzed to observe the patient and graft survival rate, growth and development of recipients and postoperative complication. Results Ten episodes of acute rejection (AR) were diagnosed in 46 cases. Four cases suffered delayed graft function (DGF), one urinary leakage and 8 drug-induced hepatic injury occurred. Eight cases suffered pulmonary infection, 3 cases suffered bone marrow depression and 2 granulocytopenia. One allograft artery stenosis and one ureteral necrosis occurred. Renal functions were returned to normal in all recipients 4 weeks after operation. The 1-year patient and graft survival rates were all 100 %, and the 3-year patient and graft survival rates were 100 % and 97.4 % respectively. Conclusions Renal transplantation is an effective treatment for pediatric and adolescent patients with end-stage renal disease. In addition to its higher AR incidence than adult, pediatric renal transplantation has especial treatment in the operation process and therapeutic regimen of immunosuppressant.
