Objective To investigate the best MR technique for detecting small epidermoids in the cerebellopontine angle.Methods 7 patients with pathologically-proved small epidermoids only located in the cerebellopontine angle were collected. The imaging techniques included:conventional T1WI and T2WI, fluid attenuated inversion recovery(FLAIR),diffusion weighted imaging(DWI) and balanced fast field echo(B-FFE) .The findings were retrospectively analyzed.Results 6 of 7 cases of epidermoid tumours localized at the cerebellopontine angle and exhibited the similar signal intensity as the cerebrospinal fluid(CSF) on T1WI and T2WI.The remaining case was slightly isointense on either T1WI or T2WI.On FLAIR images in 6 cases,3 cases showed slightly hyperintensity, 1 case showed doubtful heterogeneous signal intensity and 2 cases did not reveal any abnormal signal intensity.3 cases were hyperintense differenting from CSF on DW images. All of seven cases showed heterogeneous signal characteristics and were quite different from CFS on B-FFE.Meanwhile B-FFE also produced clearly the tissue contrast of trigeminus embedded in epidermoids of the cerebellopontine angle.Conclusion B-FFE is much more useful for the early diagnosis of epidermoids in the cerebellopontine angle and it also can provide precise preoperative information about the trigeminus encasement.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

The purpose of the study is to find the allergic reaction types and characteristics of Chinese medicine injection ( CMI). The authors monitored patients who used Shuxuetong injection, Dengzhan Xixin injection, Shenqi Fuzheng injection, Shenmai injection, Ciwujia injection, Shuxuening injection, Tanreqing injection, Reduning injection, a total of 150,000 cases were monitored. They used a nested case-control design to group the patients and obtained the serum samples from 14 allergic patients and 55 matched patients. They used enzyme-linked immunosorbent assay (ELISA) to detect serum C3, C4, IgE, IgG, MCT-P, and judge the allergic reaction types: Shuxuetong injection hypersensitivity (1 case), can not determine (1 case); Dengzhan Xixin injection hypersensitivity (1 case), hypersensitivity & anaphylactoid reaction (1 case), can not determine (1 case); Shenqi Fuzheng injection hypersensitivity (3 cases), can not determine (1 case); Shenmai injection anaphylactoid reaction (1 case); Ciwujia injection can not determine (1 case), Shuxuening injection can not determine (1 case), Tanreqing injection can not determine (1 case), Reduning injection can not determine (1 case). The results showed that the main type of allergic reaction of CMI was hypersensitivity, the type of allergic reaction was closely related to the varieties of CMI, the hypersensitivity and anaphylactoid reaction might occur in one patient at the same time which used Dengzhan Xixin injection.

To provide insights into the mechanism for the attenuate-synergistic effect of Zuota to Tibetan medicine Renqing Mangjue, a contrasted study was carried out on the pharmacokinetics of brucine and strychnine in mice plasm, which are active and toxicant ingredient in the Tibetan medicine Renqing Mangjue. LC-MS/MS was used to detect simultaneously the concentrations of brucine and strychnine in mice plasm at-different time intervals after administration parallelly and randomly, and the pharmacokinetic software Kinetica 5. 0 was selected to non-compartmental analysis (NCA) for data, and statistical analysis software SPSS 19. 0 was used for significance test on the pharmacokinetic parameters. A reliable LC-MS/MS method was established for the determination of brucine and strychnine in blood plasma, which are consistent with the requirements of the preclinical pharmacokinetic study confirmed by the methodology. The linear concentration ranges of brucine and strychnine were 0.301-104.4 µg · L(-1) (r = 0.999 5) and 0.305-106 µg · L(-1) (r = 0.999 7), respectively; The intra-day and inter-day variable coefficients were both less than 10.0% with good precision; The average extraction recoveries of brucine and strychnine were 116.23% and 112.82%, and RSD were 3.2% and 2.3% separately;The average matrix effects of brucine and strychnine were 122.48% and 116.36%, and RSD were 7.7% and 4.4%, respectively. The pharmacokinetic results showed that AUCtot of brucine and strychnine in Zuota group were both increased remarkably (P < 0.05), and the Cmax of brucine in Zuota group was about 5.25-fold higher than that of brucine in non-Zuota group (P < 0.05). The Tmax of brucine and strychnine reduced to one-eighth and one-quarter respectively compared with those in Non-Zuota group. In addition, the eliminations of brucine and strychnine in vivo were accelerated after the compatibility of Zuota. A significant difference (P < 0.05) occurred at the MRT0-t, of brucine, while the MRT0-∞ and Lz of strychnine were statistically significant upon the inspection level α = 0.1. It was found that the absorption degree of brucine and strychnine in Zuota group increased in the range of the safe dose (or concentration), while their elimination rates were accelerated, which may be one of the mechanisms for attenuate-synergistic effect of Zuota to Tibetan medicine Renqing Mangjue.
