Methods:Aflatoxin B1 was extracted from the peanut oil in soft capsules by the solvent composed of methanol and 0. 1% formic acid solution, and then centrifuged and the supernatant was purified by neutral alumina cartridges and tested after the concentration with the mobile phase consisting of methanol and 0. 1% formic acid solution with gradient elution at the flow rate of 0. 3 ml·min-1 . 25μl of the tested solu-tion was injected for the analysis at the column temperature of 30℃. Electrospray ionization ( ESI) source was applied and operated in the position ion mode. Multiple reactions monitoring ( MRM) mode was used to quantify the samples. Results:Aflatoxin B1 was in good linearity within the range of 0. 098-1. 960 μg·L-1(r=0. 999 5). The limit of detection was 0. 05 μg·L-1. The average sampling recovery was 97. 73% (n=6) with RSD of 4. 625%. Conclusion:The method is proved to be sensitive, accurate, specified and re-producible, which is referential for the assay of aflatoxin B1 in oily preparations.

Objective To investigate static closure functional characteristics of lower urinary tract in continence in late pregnancy of primigravida through perineal ultrasound and urodynamieal measurement. Methods From January of 2003 to December of 2005,83 primigravida undergoing antenatal health care in Shanghai Jiaotong University Affiliated Shanghai Sixth People's Hospital were randomly enrolled in the study, while 28 nulliparous women were recruited as control.The perineal ultrasound and urodynamical measurement were performed at the gestation age of 36-40 weeks,in both groups.We analysed the parameters of lower urinary tract function in late pregnancy compared with nullipara,such as maximal urethral closure pressure(MUCP),functional urethral length(FUL),maximal urethral pressure(MUP), valsalva leak point pressure(VLPP),postvoid residual bladder volume(PVRBV)and volume of first desire to voiding(VFDV).Results The average weight of 83 neonates was(3504?404)g.In all of 83 primigravida PVRBV was less than l0 ml.MUP(110 + 22)cm H_2O(1 cm H_2O=0.098 kPa),MUCP (96?22)cm H_2O and FUL(44?9)mm were significantly increased in the third trimester compared with nullipara(P0.05). There were 33 pregnant women suffering from urinary leakage throughout the terms.The data showed that MUCP was significantly lower in the pregnant women with symptoms of leaking than without leaking. Conclusion The static closure function increased significantly compared with nulliparous women.The VLPP was decreased and had relationship with symptoms of leakage.The results suggest that the function of lower urinary tract in continence in late pregnancy of primigravida is complex.

As a treasure resource of novel drug lead compounds, how to rapidly and high-efficiently screen and isolate active components from natural products is critical. Thanks to its high resolution, high automation and flexible integration, online two-dimensional liquid chromatography has great potential for screening active ingredients from complex matrices by integrating a highly specific bio-recognition process into a two-dimensional liquid chromatography system before, on or after the column separation. This review comprehensively summarized recent developments, applications and shortcomings of online two-dimensional liquid chromatography for natural product screening from different integration modes, including pre-column, on-column and post-column screening methods.

BACKGROUND: Liver inflammation is the main cause of severe liver diseases, including liver fibrosis, steatohepatitis, cirrhosis and hepatocellular carcinoma. Cell therapy topics are receiving increasingly more attention. The therapeutic applications of mesenchymal stem cells (MSC) have become one of the most discussed issues. While other stem cells have therapeutic effects, they have only one or two clinical applications. MSCs are responsible for repairing a variety of tissue injuries. Moreover, MSCs could be derived from several sources, including adipose tissue. MSCs are usually more abundant and easier to obtain compared to other stem cells. METHODS: To prove the concept that MSCs have homing ability to the injured tissue and assist in tissue repair, we examined the effects of intravenous injected adipose-derived mesenchymal stem cells (ADSCs) in a N-nitrosodiethylamine (DEN)-induced liver injury rat model. RESULTS: The significant repairing ability of ADSCs was observed. The levels of fibrosis, apoptosis, and tumorigenesis in the DEN-injured liver tissues all decreased after ADSC treatment. Furthermore, to enhance the therapeutic effects of ADSCs, we pretreated them with L-theanine, which promotes the hepatocyte growth factor secretion of ADSC, and therefore improved the healing effects on injured liver tissue. CONCLUSION ADSCs, especially L-theanine-pretreated ADSCs, have anti-inflammation, anti-apoptosis, and anti-tumorigenesis effects on the N-nitrosodiethylamine-induced liver injury rat model.

The content of the asarone submicro emulsion injection was determind by HPLC method, and thereby a quality evaluation method was established based on indexes of pH value, particle size, peroxide value, methoxy aniline values, free fatty acid, lysophosphatidylcholine, visible foreign substances, insoluble particle, sterility, bacterial endotoxin and impurities, etc. The results showed that the injection exhibited uniform physical appearance and all the products were in milkwhite liquid. The content of the three batches products were respectively 102.9%, 100.8%, 97.70% of the labeled amount, with mean particle size of 210-250 nm, and other indexes all met with the standards. The reserved samples showed no obvious change in terms of detection indexes and indicated good stability after the accelerated stability test and long-term stability for 12 months. The quality evaluation method established in this study could be applied to quality control and stability investigation of asarone submicron emulsion injection, which laid a basis for further clinical research and application.

In recent years, polysaccharides have received much attention because of their high safety and good immunological activity. The study of polysaccharide in vivo process is a key scientific problem that needs to be solved for polysaccharide drug development. Some progress has been made in the field of polysaccharide pharmacokinetics and immunomodulation. However, due to the lack of both chromogenic and light-absorbing groups and the complex molecular structure of polysaccharides, the in vivo processes and immunomodulatory mechanisms of polysaccharides have been slow to be investigated. The effective combination of multiple techniques can break the bottleneck of difficult tracing and unknown immunomodulatory mechanism of polysaccharides in vivo, and promote the development and utilization of polysaccharides. In this paper, we systematically summarize the key techniques in the study of polysaccharide in vivo processes and immunomodulatory mechanisms in order to provide technical references and research ideas for the study of polysaccharide in vivo processes and immunomodulatory mechanisms.
