Objective To investigate the effects of magnesium isoglycyrrhizinate on liver regeneration and hepatic function following partial hepatectomy in thioacetamide induced cirrhotic rats.MethodsForty-five cirrhotic Wistar rats undergoing 2/3 hepatectomy were randomly assigned to control group ( Group A), Group B and Group C starting the day of hepatectomy, rats in Group B were injected 60mg per kg body-weight magnesium isoglycyrrhizina daily intraperitoneally until the day of sacrifice. Rats in Group A recevied same dose of sodium chloride. In Group C, magnesium isoglycyrrhizina was administered daily 3 days before hepatectomy until the rats were sacrificed. Liver function, serum HGF, serum PLA2,BrdU labelling index and percentage of intial liver weight on days 1, 2 and 7 post hepatectomy were assessed. ResultsRats in Group A had significantly lower BrdU labelling index and serum HGF level than Group C ( t = 2. 831, P ＜ 0.05; t = 3.427, P ＜ 0.05 ) and a markedly higher level of serum PLA2 than the other groups on day 1 posthepatectomy ( Group B t = 2. 794, P ＜ 0.05; Group C t = 2. 902, P ＜ 0.05 ).Rats in Group A had a lower BrdU labelling index and a more increased level of serum PLA2 than Group B and Group C on day 2 posthepatectomy ( BrdU labelling index: Group B t = 2. 736, P ＜ 0.05; Group C t =3.083, P＜0.05; PLA2: Group B t =2.794, P＜0.05; Group C t =2.902, P＜0.05), but had no significant difference in HGF level with the other two groups. The three groups were similar in ALT, AST,TP and intial liver weight on days 1,2 after operation. On the 7th day posthepatectomy, rats in Group A had a higher level of AST ( Group B t = 4. 508, P ＜ 0.05; Group C t = 2. 967, P ＜ 0.05 ) and a lower level of TP ( Group B t = 2. 838, P ＜ 0.05; Group C t = 2. 743, P ＜ 0.05 ), lower liver weight than the other two groups ( Group B t = 3.316, P ＜ 0.05; Group C t = 4. 093, P ＜ 0.05) but there was no difference between the three groups in BrdU labelling index, HGF and PLA2 level. Rats in Group C had significantly higher BrdU labelling index and serum HGF level than the rats in Group B on day 1 after hepatectomy( t = 2. 831, P ＜0.05; t = 2. 836, P ＜ 0.05 ).ConclusionsMagnesium isoglycyrrhizinate inhibits aminopherase release and enhancing liver regeneration in cirrhotic rats after partial hepatectomy.

Objective To study the clinical, radiologic and pathologic characteristics and diagnostic methods of telangiectatic osteosarcoma for further improving the diagnostic ability.Methods The data of 10 patients with histologically proved telangiectatic osteosarcomas were retrospectively reviewed, and the clinical, radiologic and pathologic characteristics were further analysed in combination with the literature.All 10 patients were examined with X-ray and MRI, and 2 patients with CT.Results Telangiectatie osteosarcomas originated from inferior femur in 5 patients, femur neck in 1 patients, superior humerus in 2 patients and superior segment of tibia in 2 patients.The lesions showed osteolytic bone destruction on X-ray films (n = 10) and CT images ( n = 2), with mild bone expansion in 4 patients.The majority of the edge of the destroyed bone areas was unclear but without sclerotic rim.There were Codman's triangle and soft tissue mass in each patient but no obvious neoplastic bone forming.On MRI, all the lesions were mostly or completely constituted by the multiple cysts with periostnal reaction, and several scatteredly smaller liquid-liquid levels were found within cystic cavity in 7 patients.In all 10 cases, there were pathologic hemocoele similar to aneurysmal bone cysts (ABC), but malignant tumor cells and some neoplastic bones were found in cystic walls or septations.Only a small number of neoplastic bone tissue were seen by microscopy in 6 patients.Conclusions The radio-pathologic characteristics of telangiectatic osteosarcoma include the similar imaging findings of ABC, the common growth patterns of malignant tumors,and the pathologic hemocoele, malignant tumor cells within cystic wails or septations.The comprehensive analysis of clinical, radiologic and pathological data may help clinicans to make a correct diagnosis for telangiectatic nsteosareoma.

Objective To investigate the expression and clinical significance of ABCG2 protein in hepato-cellular carcinoma (HCC). Methods Specimens of HCC were collected at The First Aifiliated Hospital of Sun Yat-sen University from January 2005 to December 2006. The expression of ABCG2 protein in 165 samples of HCC tissue, 25 samples of normal liver tissue and 40 samples of cirrhotic liver tissue was detected using immunohisto-chemistry. The correlation between the expression of ABCG2 protein and clinicopathological characters was then analyzed. Enumeration data, survival rate and the difference between groups were analyzed with a chi-square test, the Kaplan-Meier method and Log-rank test, respectively. Results ABCG2 protein expression was weakly posi-tive in all normal and cirrhotic liver tissues. In HCC tissues, the expression of ABCG2 protein was strongly positive in 66 cases and weakly positive in 99 cases. The expression of ABCG2 protein was related to tumor diameter, tumor number, adjacent organ invasion and TNM stages (χ2 =8. 130, 14. 279, 4. 820, 21. 179, P <0. 05). Kaplan-Meier survival analysis revealed that patients with strongly positive ABCG2 protein had a significantly lower 3-year overall survival (24. 1%) compared with those with weakly positive ABCG2 protein (39. 4%) (χ2 = 15.716, P<0.05). Conclusions The expression level of ABCG2 protein is related to tumor invasiveness, TNM stage and prognosis. ABCG2 has the potential to become a new target for HCC treatment.

PurposeTo optimize the imaging parameters of clinical MRI scanner in rat pancreas imaging to improve the image quality and to provide better MRI image quality and more economical research method for imaging study of rat pancreas. Materials and Methods Twenty-four healthy male Wistar rats were randomly divided into the conventional sequence (CS) group, the adjustment sequence (AS) group and the optimization sequence (OS) group, with 8 rats in each group. The rats in the CS group were scanned with conventional parameters using a clinical MRI scanner. The principle of parameter adjustment was: parameters associated with T1WI or T2WI imaging quality (TR, TE, slice thickness, NEX, FOV and matrix) was set with four changes, and only one of the six parameters was changed in each scan, image quality was evaluated by two senior radiologists, the parameter corresponded the best image quality evaluated consistently by two radiologists were selected as the optimal imaging parameter, all the optimized parameters were set up step by step in this way which formed the imaging parameters in OS group. The pancreatic signal intensity and signal to noise ratio was compared between CS group and OS group after imaging.Results The optimized sequence parameters in clinical MRI scanner were listed below: T1WI sequence (M3D/FSPGR/15): TR 6 ms, TE 2.5 ms, slice thickness 2.0 mm, NEX 8, FOV 7 cm×7 cm, Matrix 120×120; T2WI sequence (FSE-XL/90): TR 4000 ms, TE 71 ms, slice thickness 2.0 mm, NEX 1, FOV 8 cm×8 cm, Matrix 192×160. The pancreatic SI in T1WI and T2WI sequence of the OS group were significantly higher than those in the CS group (t=5.16 and 3.80,P<0.01), while the pancreatic SNR in T1WI and T2WI sequence of the OS group were significantly higher than those in the CS group (t=5.65 and 3.26,P<0.01).Conclusion The optimized parameters can improve the imaging quality of rat pancreas MRI significantly, thus provide a reference for the related experimental study.
