The fluoritum is used for gynecology frequently and it's for those diseases: kidney yang deficiency, Gong cold sterility, palpitation due to fright, insomnia and dreaminess and cold cough. It's ruled in Chinese Pharmacopoeia (1985 edition) that the fluoritum originates from fluorite which belongs to fluoride minerals. Its main content is CaF2. The colors are of differents grades with purple or green. In the market, there are large differences in quality and it has various colors. Besides of the ruled color of purple and green, white and yellow are also common colors. By digging into and analysis the relevant research literature of fluorite which belongs to fluoride minerals, colors and coloration mechanism of fluorite are summarized in this paper.Natural fluorite is the mineral which has the most species of colors in nature. The different colors of fluorite are mainly caused by the impurity elements. At present, there are mainly about the coloration mechanism of fluorite: rare earth ions (4fN ions), color center, inclusions, crystalline domains or sub microscopic inclusions. The green of fluorite is produced by 570 nm and 305 nm absorption peaks which are caused by Sm2+ and compensated ions Na+ centers generated color center. The yellow of fluorite is produced by the joining of transition element, resulting in the formation of charge transfer between the crystal ions and the formation of O2-O32- ion molecule.The black of fluorite, mainly was attributed to the existence of a higher degree of evolution of organic matter. In this passage,suggestions for modification of the properties of fluoritum in Chinese Pharmacopoeia are put forward.

Pinellia Rhizoma is one of the most commonly used medicinal herbs in clinic, but its toxicity couldn't be ignored. Processing is a detoxification method before the toxic traditional Chinese medicine were given to the patients, and mainly impacted the amount of relevant components in Chinese medicinal herbs (increase or decrease). Although there were still some disputes about the toxic components in Pinelliae Rhizoma (mainly referring to the alkaloid substances), more literatures reported that needle-like calcium oxalate crystals and lectin protein in Pinelliae Rhizoma were the main toxic components, and had a significant effect on inflammation and irritation caused by Pinellia Rhizoma. With the development of research methods and the expansion of research angles, researches for the effect of processing on the detoxification mechanism of Pinelliae Rhizoma have been constantly deepened. The recent reports showed that the detoxification mechanism of the herb was correlated with the dosage of detoxifying components, and the effect of relevant excipients in inhibiting a variety of inflammatory cytokines. However, we shall also pay attention to alum and other processing accessories that could cause new toxicity from residual aluminum, and the impact from processing conditions, origin of Chinese medicinal herbs and their combination with other medicinal herbs on Pinellia Rhizoma's toxicity. This paper describes toxic components, different detoxification methods and relevant detoxification mechanisms in Pinelliae Rhizoma to provide the references for further research and development of the plant.

This is a study based on hospital intensive monitoring to explore medication use of Diemailing Kudiezi injection(one Chinese herbal medicine injection) in real word in the patients with cerebral infarction. The active monitoring model was adopted and hospital intensive monitoring on safety of 7 189 cases of patients with cerebral infarction was conducted to obtain the drug use information of Diemailing injection. The results were analyzed by using statistical description and association rule method. The statistical description and association rule analysis were conducted based on patients' basic demographic characteristics, use of Diemailing injection and combined use of drugs. Sixty-two percent(4 437/7 189) of the patients were from traditional Chinese medicine hospitals as compared with 39%(2 752/7 189) from western medicine hospitals; 84%(6 003/7 189) of the patients were from tertiary hospitals as compared with 16%(1 186/7 189) from second-class hospitals. The hospitals were mostly located in north China. Drug related indicators such as a single dripping speed, stash time after allocating transfusion, duration of injection, and injecting room temperature were not noted in instruction manual. It was also found that there were off label use in the practice, for instance, non-intravenous infusion, >14 d treatment course, use of non-designated solvent, and a single dose>40 mL or<10 mL. Analysis of association rules showed that only Edaravone among the most frequent combined drugs was listed in the current guideline in China, and the other three most frequent combined drugs deproteinized calf blood extractive injection, Cinepazide Maleate injection and Alprostadil injection were used with little evidence. Diemailing+Aspirin+Alprostadil was the most common combined use in our study, but the recommended clopidogrel+Aspirin was not found in this study. The drug use situation of Diemailing injection in the real world was obtained by data analysis on large size samples, providing basic reference information for clinicians and researchers. However, efficacy was not concerned in this study, so efficacy-related information could not be explained.

To study the pharmacokinetics of three active ingredients in Qing'e wan, namely geniposidic acid, psoralen and isopsoralen, in rats, in order to investigate their correlation in the anti-osteoporotic effect. The rats were taken blood from their eye sockets at different time points after being orally administered with raw and salt-processed Qing'e wan. Geniposidic acid, psoralen and isopsoralen in rats plasma were determined by means of UHPLC-MS/MS to draw the concentration-time curve. The proliferation rate of osteoblasts was taken as the pharmacodynamic index, and determined by MTT method to draw effect-time curve. In comparison between the effect-time curve and the concentration-time curve, the blood concentrations of geniposidic acid and psoralen were close to the peak when the cell proliferation rate reached its peak, indicating a good correlation between them. The peak blood concentration of isopsoralen was slightly lagging behind the peak of efficacy. According to the correlation analysis after fitting the effect-time curve and the concentration-time curve, salt-processed Qing'e wan had a better correlation than the raw one. The above experimental results showed that the effect-time curve and the concentration-time curve of geniposidic acid and psoralen had a good correlation, and the correlation of salt-processed Qing'e wan was better than the raw one.

To systematically review the clinical efficacy and safety of Yinzhihuang oral liquid in the treatment of intrahepatic cholestasis of pregnancy(ICP). Literatures published by June 2016 were searched in databases, such as Medline, Pubmed, Cochrane Library, China National Knowledge Infrastructure(CNKI), Chinese Scientific Journals Full-text Database(VIP), Chinese biomedical literature database(CBM), and Wanfang Database. Randomized controlled trials(RCT) of Yinzhihuang oral liquid were collected according to the inclusion criteria, and the methodological quality of selected literatures was evaluated. The Meta-analysis was conducted by using RevMan 5.3 software. A total of 7 RCTs involving 711 patients were included. The results of Meta-analysis showed that, compared with control group, Yinzhihuang oral liquid significantly alleviated pruritus symptoms[MD=-0.68, 95%CI(-0.95,-041), P<0.000 01], reduced blood biochemical indexes including TBA[MD=-7.23, 95%CI (-10.88,-3.58), P=0.000 1], TB[MD=-1.90, 95%CI(-3.09,-0.70), P=0.002], ALT[MD=-39.08, 95%CI (-56.46,-21.70), P<0.000 1], and CG [MD=-0.71, 95%CI(-0.89,-0.52), P<0.000 01]. In the respect of pregnancy outcome, Yinzhihuang oral liquid can distinctly improve birth weight [MD=430.03, 95%CI (219.28, 640.78), P<0.000 1]. However, there was no significant difference in cesarean section rate [OR=0.93, 95%CI (0.36, 2.36), P=0.87], preterm birth rates [OR=0.63, 95%CI (0.28, 1.42), P=0.26], and neonatal asphyxia rate [OR=0.50, 95%CI (0.18, 1.43), P=0.20]. Yinzhihuang oral liquid showed better efficiency and slighter adverse reaction. However, more rigorously designed, double-blind, randomized controlled trials with large sample size and high quality are required to provide further evidences.

To study the hepatotoxicity of emodin based on bilirubin metabolism mediated by glucuronidation of UGT1A1 enzyme. In this study, three different incubation systems were established by using RLM, HLM, and rUGT1A1, with bilirubin as the substrate. Different concentrations of bilirubin and emodin were added in the incubation systems. The double reciprocal Michaelis equation was drawn based on the total amount of bilirubin glucuronidation. The apparent inhibition constant Ki was then calculated with the slope curve to predict the hepatotoxicity. The results indicated that emodin had a significant inhibition to the UGT1A1 enzyme in all of the three systems, with Ki=5.400±0.956(P<0.05) in HLM system, Ki =10.020±0.611(P<0.05) in RLM system, Ki=4.850±0.528(P<0.05) in rUGT1A1 system. Meanwhile, emodin had no significant difference between rat and human in terms of inhibition of UGT1A1 enzyme. Emodin had a potential risk of the hepatotoxicity by inhibiting the UGT1A1 enzyme activity. And the method established in this study provides a new thought and new method to evaluate hepatotoxicity and safety of traditional Chinese medicines.
