We report the synthesis and structural characterization of a 2D metal-organic framework with AB-packing layers, [Co(pybz)(CHCOO)]·DMF (, pybz= 4-(4-pyridyl)benzoate), containing a stable (4,4)-grid network fabricated by paddle-wheel nodes, ditopic pybz, and acetate ligands. After removal of the guest, the layer structure is retained but reorganized into an ABCD packing mode in the activated phase (). Consequently, the intralayer square windows (7.

Methods: The plasma sample was simply deproteinized with acetonitrile, extracted three times by aceticether, evaporated to dryness with a gentle N2 stream, dissolved with methanol and determined by HPLC. The pharmacokinetic parameters were separately calculated and compared with data processing software DAS 2.
Objective: To study the relationship between HPLC characteristic spectrum and pharmacodynamics on anti-myocardial ischemia of GualouXiebai dropping pills.
Methods: HPLC characteristic spectrum of GualouXiebai dropping pills was established, dropping pills were divided into five dose groups (3.75, 11.
Objective: To study the pharmacodynamics of Gualou Xiebai Dropping Pills and its medicinal ingredients in prescription on anti-myocardial ischemia.
Methods: SPF Rats were divided randomly into eleven groups with ten rats in each group and half male and half female, the rats were respectively given the physiological saline(blank group and model group), Gualou, Xiebai, Gualou Xiebai Baijiutang (all equivalent to the crude herb of 22. 5 g/kg), Gualou Xiebai.
In cancer, gene silencing via hypermethylation is as common as genetic mutations in p53. Understanding the relationship between mutant p53 and hypermethylation of other tumor suppressor genes is essential when elucidate mechanisms of tumor development. In this study, two isogenic human B lymphoblast cell lines with different p53 status include TK6 containing wild-type p53 and WTK1 with mutant p53 were used and contrasted.
