China Pharmacy 2007;0(31):-
OBJECTIVE: To evaluate the in vitro and in vivo antibacterial activities of cefodizime from both home and abroad. METHODS: The minimal inhibitory concentrations (MICs) of domestic and imported cefodizime, cefotaxime sodium against 300 clinical isolates of bacteria were tested by standard agar dilution method and the test tube dilution method. The in vivo antibacterial activities of cefodizime were determined in mice with experimental systemic infection caused by E.coli, K. pneumoniae and S.aureus. The values of ED50 were calculated by Bliss method. RESULTS: Both domestic and imported cefodizime had remarkable potency against majority gram- negative bacteria and gram- positive bacteria, including pneumococcus and beta streptococcus, and the MIC90 of cefodizime stood at 0.012~1.0?g?mL-1; and they showed medium grade antibacterial activity against bacillus cloacae, bacillus aerogenes and serratia but mild effects on MSSA and S.epidermidis, and the MIC50 stood at 4?g?mL-1. In this trial, bacillus aeruginosus, acinetobacter, enterococcus and MRSA showed resistance against the domestic and imported cefodizime. The in vivo antibacterial activities of domestic and imported cefodizime were similar and remarkable in mice infected with E.coli, K.pneumoniae and S.aureus. CONCLUSION: Domestic and imported cefodizime had excellent and similar antibacterial activity.

inflammatory pseudotumor. Conclusions The number of pleural is closely relative to the shape size and position. The occurrence rate of pleural indentation is closely relative to the distance between SPN and pleural,and the nature of SPN has correlation with pulling pleural.

Objective To investigate somatostatin receptor subtype 2 (SSTR2) mRNA expression and its correlation with proliferating cell nuclear antigen (PCNA) in human colorectal cancer. Methods A total of 60 colorectal cancer samples were analyzed. The SSTR2 mRNA expression was examined by in situ hybridization (ISH) using multiphase oligoprobes. The PCNA were detected by immunohistochemical staining. A computerized image analysis system was utilized to estimate the relative contents of SSTR2 mRNA. Results The positive rate of expression of SSTR2 mRNA and relative contents in early and well-differentiated colorectal cancer were higher than those in advanced and poorly differentiated lesion. A negative correlation between SSTR2 mRNA expression and PCNA was found in colorectal cancer. Conclusion In the samples of colorectal cancer, the expression of SSTR2 mRNA is correlated with the degree of differentiation and clinical stage, and it plays an important role in reflecting the degree of malignancy and prognosis.
6. Determination of Plumbago content in Herba Plumbaginis Zeylanicae under different growing conditions
Chinese Pharmaceutical Journal 2012;47(10):834-837
OBJECTIVE: To determine Plumbago content in Herba Plumbaginis Zeylanicae under different growing conditions and to provide experimental data for its domestication. METHODS: High performance liquid chromatography was used to determine Plumbago contents in the roots, stems and leaves of home-grown Herba Plumbaginis Zeylanicae. RESULTS: Plumbago content in Herba Plumbaginis Zeylanicae grown in mellow and clay soil was higher than in those grown in sand and crude soil. Potasium-fertilized and nitrogen-fertilized Herba Plumbaginis Zeylanicae contained higher Plumbago than those fertilized by phosphorus. Plumbago content was the highest in Herba Plumbaginis Zeylanicae grown in full light. Plumbago contents in roots, stems, and leaves of Herba Plumbaginis Zeylanicae grown under different bred conditions did not vary much. CONCLUSION: The research group's preliminary studies indicated that Plumbago was the main effective ingredient having anti-cancer and anti-inflammation bioactivity. Clay soil, cuttings, potassium fertilizer and nitrogen fertilizer, and full light were thought as ideal conditions for increasing Plumbago content. High quality Herba Plumbaginis Zeylanicae can be grown under these conditions. Copyright 2012 by the Chinese Pharmaceutical Association.

Objective:To study the inhibitory effect of salidroside on the proliferation of fibroblast-like synoviocytes with rheumatoid arthritis in human(HFLS-RA) induced by tomor necrossi factor-α(TNF-α),and to clarify the molecular mechanism of its control effect on rheumatoid arthritis(RA).Methods:The HFLS-RA were cultured in vitro,then treated with TNF-α and different concentrations of salidroside.The cells were divided into normal control group(0 μg·L-1TNF-α),model control group(10.0 μg·L-1TNF-α)and 12.5,25.0,50.0,and 100.0 μmol·L-1 salidroside groups(10.0 μg·L-1TNF-α+salidroside).The proliferation activity was detected by MTT mehthod;the expression levels of β-catenin,matrix metalloproteinase-7(MMP-7),and Cyclin-D1 in supernatant of the cells were detected by ELISA method;the expression level of β-catenin protein in cells was detected by Western blotting method.Results:Compared with normal control group,the proliferation activity of the HFLS-RA in model control group was significantly increased (P<0.05);compared with model control group,the proliferation activities of the HFLS-RA in 12.5 and 25.0 μmol·L-1 salidroside groups were decreased but there were no significant differences(P>0.05),and the proliferation activities of the HFLS-RA in 50.0 and 100.0 μmol·L-1 salidroside groups were significantly decreased (P<0.05).Compared with normal control group,the expression levels of β-catenin,MMP-7,and Cyclin-D1 in the supernatant of the cells in model control group were increased(P<0.05).Compared with model control group,the expression levels of β-catenin,MMP-7,and Cyclin-D1 in the supernatant of the cells in 12.5 and 25.0 μmol·L-1 salidroside groups were decreased,but there were no significant differences(P>0.05);the expression levels of β-catenin,MMP-7,and Cyclin-D1 in the supernatant of the cells in 50.0 and 100.0 μmol·L-1 salidroside groups were decreased(P<0.05).The Western blotting results showed that the expression level of β-catenin protein in the cell in model control group was higher than that in normal control group(P<0.01);the expression levels of β-catenin protein in the cells in 12.5 and 25.0 μmol·L-1 salidroside groups were lower than that in model control group,but there were no significant differences(P>0.05);the expression levels of β-catenin protein in the cells in 50.0 and 100.0 μmol·L-1 salidroside groups were lower than that in model control group(P<0.05).Conclusion:Salidroside could inhibit the proliferation of HFLS-RA,and its control effect might be related to the regulation of Wnt/β-catenin single pathway.
