Objective:To summarize the drug interactions of haloperidol used in combination with the other drugs to provide refer-ence for safe, reasonable and effective use of haloperidol in clinics. Methods:By retrieving Micromedex? , Pubmed, CNKI and so on, the interactions between haloperidol and the other drugs were summarized and analyzed. Results:The effect of haloperidol was on do-pamine receptors, and haloperidol was mainly metabolized by hepatic cytochrome P450 ( CYP) enzymes. When haloperidol was com-bined with the other drugs, significant interactions of pharmacokinetics and pharmacodynamics were induced by affecting CYP enzymes or dopamine receptor. Conclusion:In clinical practice, the other drugs combined with haloperidol should be reasonable and careful to ensure safe, effective and rational drug use.

Objective:To separate and purify the immunoactive polysaccharide RTPS- I from Trichosanthis Radix and study the physicochemical properties and preliminary structure. Methods:The crude polysaccharides were extracted by water, and then precipita-ted by ethanol. After the deproteinization with trichloroacetic acid, the polysaccharide RTPS-I was separated and purified by using DE-AE-Cellulose, DEAE-Sepharose FF and Sephadex G-200 column chromatography. The analysis of properties and structure was per-formed by using GC, HPGPC, IR and NMR. Results:RTPS-I was a white flocculent solid after vacuum freeze-drying, and soluble in water. It contained three elements (carbon, hydrogen and oxygen) with the specific rotation [α]25D (H2O) of +164. 44 and the relative molecular mass of 17555. The glycosyl in RTPS- I was composed of glucose without uronic acid. The sugar ring was pyranoid ring, and each monosaccharide was linked by α-glycosidic bond. Conclusion: A homogeneous immunoactive polysaccharide RTPS- I from Trichosanthis Radix is isolated for the first time.

Objective:To prepare mesalazineβ-cyclodextrin inclusion compound and observe its properties. Methods:The struc-ture was characterized by UV, IR and DSC. The inclusion process of mesalazine andβ-cyclodextrin was simulated using molecular doc-king technique. The solubility and dissolution of inclusion compound were determined. Results:UV, IR and DSC were used to deter-mine the formation of inclusion complex. The inclusion ratio was 1: 1 and the phase solubility diagram was AL type. The solubility of inclusion compound in deionized water (25 ℃, pH 7. 0) was 7. 8 mg·ml-1 . The preparation of mesalazine β-cyclodextrin inclusion compound could significantly increase the dissolution rate and solubility of mesalazine. Conclusion:The prepared mesalazineβ-cyclo-dextrin inclusion compound can obviously improve the poor water solubility and dissolution of mesalazine.

Objective:To perform textual researches on name, origin and distribution of Maidong to clarify the medicinal varieties and history recorded in ancient literatures and provide evidence for clinical use. Methods:Ancient herbal works were performed textual research, and the resource investigation and modern data were analyzed. Results:According to the ancient herbal records and modern researches, Maidong had lots of alias, while only Maimendong and Maidong were used as the medicine common names. According to the records of main origin, original plant morphological and medicinal characteristics of Maimendong, it was preliminarily concluded that Maidong recorded in the ancient herbal records was mainly produced in Jiande of Zhejiang province, Mianyang of Sichuan prov-ince, Xiangyang of Hubei province and the surrounding areas. The chemical compositions and pharmacological activities of Maidong and Shanmaidong were similar;therefore, they both could be used as the medicines. Conclusion:In the light of the ancient and mod-ern medicinal customs, modern chemistry and pharmacology researches and clinical practice of TCM, it deserves further discussion on whether Maidong and Shanmaidong can be used as multi source varieties of traditional Chinese medicines just like Polygonaceae plants palmatum L. , Rheum tanguticum Maxim, ex Balf. and Rheum officinale Baill. , and Ranunculaceae plants Coptis chinensis Franch. , Coptis deltoidea C.
