A Retrospective Analysis on 1330 Adverse Event Reports of Qingkailing in China: Further Perception of Its Risks and Rational Use.

Qingkailing (QKL) is a modern preparation exploited according to the traditional Chinese medicine theory. It becomes the second leading cause of adverse drug events (ADEs) in all traditional Chinese medicine injections. The safety evaluation and rational use of QKL are of special importance.

Investigation of the synergistic effects of haloperidol combined with Calculus Bovis Sativus in treating MK-801-induced schizophrenia in rats.

Clinical studies that focused on treating schizophrenia showed that Calculus Bovis Sativus (CBS), a substitute of Calculus Bovis, when used in combination with haloperidol could significantly lower the dosage of haloperidol compared with treatment with haloperidol alone, whereas efficacy was maintained. The aim of this study was to investigate the synergetic anti-schizophrenia effects in rats using CBS in combination with haloperidol. An open field test was conducted to verify the pharmacodynamic effects of a combination treatment of CBS and haloperidol on MK-801-induced schizophrenic rats.

[Density functional theory investigations of the spectroscopic characteristics and luminescent mechanisms of dipterex and dichlorvos].

By using G09 program package, the ground-state structures, infrared spectra, NMR spectra, UV-Vis spectra as well as the excited structures and fluorescence/phosphorescence spectra of dipterex and dichlorvos were investigated systematically, and luminescence principles were analyzed with the molecular orbitals to provide the theoretical foundation for the detection of trace dipterex and dichlorvos. Our theoretical model revealed that the IR spectra of dipterex and dichlorvos bear strong absorptions at about 1107 cm(-1), which belong to the P-O stretch modes, but dipterex has strong absorption peaks involving the O-H bond; for UV-Vis spectra, dichlorvos has a strong absorption peak at 182.03 nm, but dipterex has a weak one at 192.

2-(1H-1,2,3-Benzotriazol-1-yl)-N'-(2-chloro-benzyl-idene)acetohydrazide.

In the title compound, C(15)H(12)ClN(5)O, the mean planes of the benzotriazole and chloro-phenyl fragments form a dihedral angle of 70.8 (1)°. In the crystal, mol-ecules are linked into infinite chains along the a axis by N-H⋯O hydrogen bonds.
