Objective To investigate the effects of 1-deoxynojirimycin ( DNJ) on the proliferation and the synthesis of extracellular matrix ( ECM ) in mouse mesangial cells cultured in high glucose. Methods The mouse mesangial cell line was cultured.The proliferation of the cells was detected by MTT assay.The concentration of type Ⅳ collagen ( ColⅣ) and fibronectin ( FN) was examined with ELISA in cultured medium of mouse mesangial cells.The expression of the mRNA of TGF -β1 and PPARγwas detected by RT-PCR.The expression of the protein of TGF-β1 was detected by Western Blot. Results (1)High glucose significantly stimulated the proliferation of the cells treated for 48 h as compared to normal glucose group (NG) and mannitol group (MG) (P<0.05).Compared with NG and MG,the remarkable inhibition effect was observed by high glucose for 72 h and 96 h ( P <0 .05 ) .There was no significant difference between mannitol group ( MG ) and NG ( P >0.05 ) .( 2 ) DNJ significantly inhibited the proliferation of mouse mesangial cells cultured in high glucose.The effect of DNJ was time and dose-dependent.The further research was made in the cells treated with high glucose +5 mmol/L DNJ for 48 h. ( 3 ) High glucose increased the expression level of TGF-β1 mRNA and PPARγmRNA and the synthesis of ColIV and FN ( P<0 .05 或P <0 .01 ) .There was no significant difference between MG and NG ( P >0.05).(4)DNJ could decrease the expression level of TGF-β1 mRNA and the synthesis of ColIV and FN of cells cultured in high glucose ( P <0.05 ) , while DNJ had no effect on increased expression level of PPARγmRNA of cells cultured in high glucose. Conclusion DNJ inhibits proliferation and ECM synthesis of mesangial cells cultured in high glucose, which may be mediated by downregulating the expression of TGF-β1 mRNA.

Pyrrolizidine alkaloids(PAs) are a kind of natural toxins, which can cause severe hepatotoxicity, pulmonary toxicity, genotoxicity, neurotoxicity, embryotoxicity and even death. Therefore, international organizations and countries such as World Health Organization have paid great attention to herbal medicines and preparations containing PAs. PAs are widely distributed in Chinese herb medicines and contained in hundreds of traditional Chinese medicine preparations. The content of adonifoline, the main PAs in Senecionis Scandentis Herba, shall be less than 0.004% in herbal medicines as described in Chinese pharmacopeia. However, there is no guidance in preparations which contain Senecionis Scandentis Herba. In this study, 14 preparations were analyzed by an UPLC-MS method. Among them, 8 preparations were found to contain adonifoline much higher than the content limits of such countries as Germany, Netherlands and New Zealand. And the highest contents of adonifoline were found in Qianbai Biyan Tablets and Qianbai Biyan Capsules, which are officially recorded in Chinese Pharmacopeia. The contents of adonifoline varied in different batches of the same preparations. The highest content was 156.10 μg·g~(-1) Qianbai Biyan Tablets, whose daily intake of adonifoline was up to 1 030.26 μg according to the recommended dosage of the preparation. Our results showed the potential risk of these preparations, and the content limit of adonifoline shall be inspected Chinese medicine preparations containing Senecionis Scandentis Herba.

Drug-induced liver injury and herbal preparations containing pyrrolizidine alkaloid (PA) have gained global attention. The purpose of this research was to investigate the effects and mechanisms of Alismatis Rhizoma, a traditional Chinese medicine, to protect against acute liver injury in mice induced by senecionine (SEN), a representative toxic PA compound. All experiments were approved by the Animal Research Committee of Shanghai University of Traditional Chinese Medicine. Animal welfare and the animal experimental protocols were strictly consistent with related ethics regulations of Shanghai University of Traditional Chinese Medicine. Acute liver injury was induced by a single intragastric administration of SEN (50 mg·kg^-1). Mice in the protection groups received intragastric administration of Alismatis Rhizoma water extract (WE, 18 g·kg^-1 per day) or ethanol extract (EE, 18 g·kg^-1 per day) 5 days before SEN treatment. The results show that Alismatis Rhizoma extracts can significantly attenuate acute liver injury in mice. Mice in the protection groups showed decreased serum activities of alanine aminotransferase and aspartate aminotransferase, as well as decreased total bile acids. In addition, the infiltration of inflammatory cells, sinusoidal hemorrhage, and hepatic necrosis in SEN-treatment mice was clearly attenuated in the protection groups. Interestingly, EE showed a better effect than WE. The content of principal bile acids in serum and the mRNA and protein expression of key factors related to bile acid metabolism were also measured. Alismatis Rhizoma up-regulated the bile acid transporters and drug metabolism enzymes, consistent with the observed bile acid homeostasis and alleviation of SEN-induced injury to hepatocytes. The present study points to the possibility of utilizing Alismatis Rhizoma for protection against liver injury caused by drugs and preparations containing PA.

Objective: To study the correlation between the content changes of main medicinal ingredients and the color values of Rhei Radix et Rhizoma during storage based on the principle of chromaticity analysis,and to provide reference for studying on the mechanism of discoloration and improving the quality evaluation of Rhei Radix et Rhizoma. Method: Simulated accelerated test was adopted in this study, where Rhei Radix et Rhizoma was stored under high temperature(40±5)℃,high humidity RH(92.5±5)%and strong light(4 000±500)Lx conditions to accelerate its discoloration. For the samples taken at different time points,the color value was determined by spectrophotometer and the total contents of anthraquinone and free anthraquinones,sennoside A,B,catechin and gallic acid were determined by high performance liquid chromatography (HPLC). The correlation between the effective components and the color value of rhubarb was analyzed by SPSS software. Result: During the storage process,it was observed by the eye that the color of Rhei Radix et Rhizoma was significantly darker and darker in the simulated acceleration test. According to the analysis of the chromaticity value results,the changes of chromaticity values L^*and E^*ab of Rhei Radix et Rhizoma were significantly negatively correlated with free strontium content(P<0.05),and significantly positively correlated with catechin content(P<0.05),but there was no correlation with total anthraquinones and sennoside A. The chromaticity value a^* was significantly negatively correlated with gallic acid(P<0.05) and significantly positively correlated with sennoside B(P<0.05). Conclusion: There is a certain correlation between the change of color value and the content of six medicinal ingredients during Rhei Radix et Rhizoma storage.
