The zebra fish model, as an integral animal model, features small volume, high throughput, low cost, short cycle and reliable experimental results, thus has been widely used in medical studies. Traditional Chinese medicines (TCM) constitute a complex system, their active ingredients and action mechanisms are among study hotspots in during the development of modern TCMs. Along with the constant improvement of advanced technologies and methods, zebra fishes have been increasingly applied in studies on TCMs and shown advantages in active screening, and toxicity and metabolism studies. In this paper, TCM studies by using zebra fishes in recent years are summarized to provide new ideas and methods for basic studies on TCMs.

Toxic epidermal necrolysis (TEN) is an acute skin inflammation,which belongs to heavy drug eruption.With the extensive and widespread use of antibiotics,nonsteroidal antipyretic analgesics and other pharmacotherapies in the treatment of critically ill patients,the trend of morbidity of TEN is gradually increased,especially in intensive care unit.In consideration of the high mortality rate of TEN and its great influence on the overall prognosis of patients with critical illness,we summarized the diagnosis and treatment experiences in the management of TEN based on retrospective analysis of one patient with severe acute pancreatitis and TEN.

Objective To evaluate the antitumor effect of corosolic acid and its impact on CAM and YSM angiogenesis.Methods The effects of CRA on A549 proliferation was studied by MTT method in vitro.Tumor-bruden nude mice model were established by injecting A549 lung cancer cell marked with bioluminescent to nude mice,and the growth of tumor in mice were detected by IVIS small animal in vivo imaging system.Experiment of chicken embryos eggs are used to observe the role of drugs on CAMand YSMblood vessels. Results The value of IC50 of CRA for A549 in vitro was 26.8μg/mL.A tumor-burdened animal experiment results showed that the CRA to A549 solid tumor has a certain therapeutic effect.CAM and YSM blood vessels of chicken embryos eggs treated with CRA were decreased significantly than negative control group.Conclusion CRA has certain therapeutic effect for A549,which may be related to the inhibition of angiogenesis in tumor tissues.

Objective To investigate the expression level of cyclooxygenase-2 (COX-2) and its effects on cell proliferation activity and apoptosis in colorectal carcinoma. Methods The expression of COX-2, proliferating cell nuclear antigen (PCNA) and apoptosis in 60 cases of colorectal carcinoma, 20 cases of colorectal adenoma and 20 cases of normal mucous were studied by the immunohistochemical and TUNEL methods, the apoptosis index(AI)and proliferation index(PI) were defined respectively. Results The positive expression rate of COX-2 in colorectal carcinoma was significantly higher than that in the other groups. Overexpression of COX-2 in colorectal carcinoma was related to its lymph node metastasis and the size of tumor and clinical stages. In the group with COX-2 positive expression, PI was higher than that in the group with COX-2 negative expression; whereas AI was higher in the latter group than in the former group. Conclusions The expression level of COX-2 may have a close correlation with cell proliferation and apoptosis, they may participate in oncogenesis and progression of colorectal carcinoma.

Objective To explore the clinical efficacy and safety of modified Ponticelli regimen in treating patients with idiopathic membranous nephropathy (IMN).Methods A retrospective analysis was performed in 90 patients with IMN (type Ⅰ / Ⅱ,79/11 respectively) diagnosed by clinical data and renal biopsy.The patients were divided into modified Ponticelli group (n =23),steroid plus cyclophosphamide (CTX) (CTX group,n =39) and steroid plus cyclosporine A(CsA) (CsA group,n =28) according to the treatment.Liver function,renal function,serum lipid,proteinuria were recorded before and after treatment.Efficacy and adverse reactions were evaluated in three groups.Results (1) In all three groups,the quantity of proteinuria after treatment for 3 months [(3.33 ± 1.53) g/d,(4.70 ± 2.97) g/d,(3.92 ± 2.57) g/d],6 months [(1.60 ± 1.10) g/d,(2.34 ± 1.61) g/d,(2.25 ± 1.78) g/d] was significantly decreased compared with baseline level[(7.26 ± 2.06) g/d,(7.50 ± 2.55) g/d,(7.54 ± 2.70) g/d;P ＜ 0.05].Serum albumin levels at 3 months [(31.42 ± 3.86) g/d,(30.59 ± 5.79) g/d,(30.90 ± 7.87) g/d],6 months [(36.25 ± 4.20) g/d,(34.70 ± 6.70) g/d,(35.36 ± 8.29) g/d] were significantly increased compared with baseline levels [(24.13 ± 2.61) g/d,(23.98 ± 3.79) g/d,(22.94 ± 4.57) g/d;P ＜ 0.05],whereas serum creatinine at 3 and 6 months had no significant changes (P ＞ 0.05).(2) After treatment for 3 months,partial remission rates in modified Ponticelli group,CTX group and CsA group were 39.1％,35.9％,35.7％ respectively and complete remission rates were 8.7％,5.1％,10.7％,which were not statistically significant in all three groups (P ＞ 0.05).At 6 months,partial remission rates in three groups were 56.5％,41.0％,42.9％ respectively and complete remission rates were 21.7％,20.5％,28.6％,which did not suggested significant difference in all three groups either (P ＞ 0.05).(3) In modified Ponticelli group,steroid diabetes,impaired liver dysfunction,infections and gastrointestinal adverse events occurred in 1,1,2 and 2 patients,respectively.In CTX group,steroid diabetes,infections and gastrointestinal adverse events occurred in 5,8 and 2 patients,respectively.In CsA group,steroid diabetes and infections occurred in 1 and 3 patients,respectively.Conclusion Modified Ponticelli regimen to treat patients with IMN has a trend of better outcome than classic CTX regimen.The efficacy is not inferior to CsA regimen with fewer side effects.

Objective To observe the clinical effect of treating advanced esophageal carcinoma with three-dimensional conformal radiotherapy combined with chemotherapy and traditional Chinese medicine.Methods 36 cases with advanced esophageal carcinoma were randomly divided into a eontrol group and a treatment group.The control group was treated with conventional radiotherapy combined with chemotherapy,and the treatment group was treated with three-dimensional conforrnal radiotherapy combined with chemotherapy and traditional Chinese medicine.The short-term effect,toxicity and long-term effect were observed,and cause of death was analyzed.Results The complete remission rate in the treatment group was significantly higher than that of the control group(P＜0.05).The toxicity of the treatment group was markedly decreased.One and three years'survival rate between the two groups had a significant difierent(P＜0.05),but five years'survival rate between the two groups had no significant difference(P＞0.05).Local uncontrolled rate and recurrence rate in the treatment group were significantly lower than those in the control group(p＜0.05).Conclusion The treatment of three-dimensional conformal radiotherapy combined with chemotherapy and traditional Chinese medicine on advanced esophageal carcinoma was better than conventional radiotherapy combined with chemotherapy.

Objective To investigate the expression of scaffold protein palladin in pancreatic ductal adenocarcinoma (PDAC) tissues and to discuss its clinicopathological significance.Methods 56 samples of PDAC and corresponding adjacent normal pancreas (NP) tissues were collected.Another 10 samples of chronic pancreatitis (CP) tissues were collected.Western blot analysis and immunohistochemistry assay were performed to detect the expression of protein palladin.The correlation of palladin expression with clinicopathological factors of PDAC was analyzed.Results Western blot analysis revealed that the expression of palladin in PDAC,CP and NP tissues were respectively 0.93±0.07,0.41±0.07 and 0.20±0.06,and the expression of palladin was significantly increased in PDAC tissues compared with NP and CP tissues (P ＜ 0.05),and its expression was significantly increased in CP tissues compared with NP tissues (P ＜ 0.05).Immunohistochemical staining showed that palladin was mainly expressed in activated myofibroblasts in PDAC tissues.The rate of palladin expression was 79 ％ (44/56),which was higher than that in NP tissues (2/10) and CP tissues (4/10),and its expression was found to be correlated with the degree of tumor differentiation,lymph node metastasis and clinical TNM classification (P ＜ 0.05),and it had no correlation with patient' s sex,age,tumor location and distant metastasis (P ＞ 0.05).Conclusions Scaffold protein palladin is highly expressed in PDAC tissues,and it is expressed in the activated myofibroblasts within tumor microenvironment.Scaffold protein palladin may be involved in the invasion and metastasis of PDAC.
