Research on the quality standard of Baoyun pill / 国际中医中药杂志

Objective To improve the quality standard of Baoyun pill. Methods The natures of Psoralea corylifolia, Radix Dipsaci and Loranthus parasiticus were detected by thin layer chromatography (TLC); the content of Hesperidine were measured by high performance liquid chromatography (HPLC). The operating conditions by HPLC were InertSustain C18 (4.6 mm×250 mm, 5 μm ), the mixture of methanol-acetic acid-water (35:4:61) as mobile phase, 1.0 ml/min as flow speed and wavelength 283 nm. Results The results showed that the TLC spots of Psoralea corylifolia, Radix Dipsaci and Loranthus parasiticus were fairly clear, and the according blank test showed no interference. Hesperidine showed a good linear relationship within the range of 0.820-4.920 μg(r=1.000 0)with an average recovery of 99.85%(RSD=0.21%).Conclusions The TLC and HPLC are handy,safe and accurate for Baoyun pills to determine the quality.

Inhibitory effect of selective cyclooxygenase-2 inhibitor NS-398 on proliferation and invasion of human colorectal cancer cells / 第二军医大学学报

Objective:To investigate the effect of NS-398,a selective cyclooxygenase-2(COX-2) inhibitor,on the proliferation and invasion of human colon carcinoma cells in vitro,so as to determine the possibility of COX-2 as a new target for treatment of colon carcinoma.Methods: The expression of COX-2 in colorectal cancer cells(CW-2,COLO-320) was detected by RT-PCR and Western blotting.COLO-320 cell proliferation was measured by MTT after treatment with NS-398.Cell invasion ability was measured using migration and invasion chamber systems.Western blotting assay was used to examine the influence of NS-398 on MMP-2 expression.Results: Our results showed that CW-2,COLO-320 cells expressed COX-2 mRNA and protein.NS-398 inhibited the proliferation of COLO-320 cells in a time-and concentration-dependent manner.Invasion test showed that NS-398 inhibited the migration and invasion of COLO-320 cells.Western blotting revealed that NS-398 inhibited the expression of MMP-2 in COLO-320 cells.Conclusion: The selective COX-2 inhibitor NS-398 can inhibit COLO-320 cell proliferation and invasion,indicating COX-2 may serve as a new target for colon carcinoma treatment.

The Challenges and Opportunities for Traditional Pharmacies in Digital Network Time / 中国药房

OBJECTIVE: To discuss the challenges and opportunities for traditional pharmacies in digital network time. METHODS: Aiming at the problems occurring in the work of pharmacy and pharmaceutical care, we analyzed the meaning and deep impact of the using of network information technology in pharmacy .RESULTS: It is clear that the drug supply ori- ented pharmacies should be transformed to pharmaceutical care oriented pharmacies. It is very important to use computer high text to handle pharmaceutical information efficiently.CONCLUSION: The digital networks can extend the work of pharma- ceutical care in space and time and provide an opportunity to the development of pharmacies.
