RESUMO
ObjectiveHenoch-Schönlein purpura（HSP） is one of the dominant diseases in Mongolian medicine. Qishun Baolier（QSBLE）， as the main prescription for the treatment of HSP， has significant clinical effect， but its mechanism is not yet clear. Baed on this， this study is intended to screen the differentially expressed proteins before and after treatment， and preliminarily explore the molecular mechanism of QSBLE in the treatment of HSP. MethodTaking oneself as the control， 30 HSP patients aged 6-45 years were collected， and QSBLE was taken orally at 12：00 and 24：00， respectively. The dose was adjusted according to age and the course of treatment was one week. The distribution of proteinuria， hematuria and skin purpura of all patients were determined before and after treatment. The serum samples of 10 patients with clinically significant remission after QSBLE treatment were randomly selected for proteomics. Isobaric tags for relative and absolute quantification（iTRAQ） combined with liquid chromatography tandem mass spectrometry（LC-MS/MS） was used to analyze the proteins in serum of HSP patients before and after treatment， and differential proteins were analyzed bioinformatically and the protein-protein interaction（PPI） networks were constructed. ResultA total of 378 proteins were identified from serum， including 18 differentially expressed proteins， of which 15 proteins were up-regulated and 3 proteins were down regulated. Bioinformatics showed that the differential proteins were mainly involved in biological processes such as immune response， immunoglobulin production， phagocytosis， adaptive immune response before and after treatment. Biological processes， pathways and proteins were used to construct the PPI network， the proteins represented by immunoglobulin heavy constant γ1（IGHG1）， immunoglobulin λ-chain 7-43（IGLV7-43）， gelsolin（GSN） and 60 kDa heat shock protein（HSPD1） were involved in biological processes and related pathways such as adaptive immune response， immunoglobulin production， leukocyte-mediated immunity， regulation of stress response， regulation of immune system processes， regulation of trauma response， and these proteins were at the center of the PPI network. ConclusionQSBLE may play a role in the treatment of HSP by regulating the expression of IGHG1， IGLV7-43， GSN， HSPD1 and other key proteins to affect immune-related biological processes.
RESUMO
Sugemule-10, one of the traditional Mongolian medicine (TMM) formulae, is derived from Four Medical Classics (Vol. 4) and composed of 10 Mongolian medicines. It is used to treat kidney cold, low back pain, urinary obstruction, kidney/bladder stones, and is the main prescription for kidney cold. The current research on Sugemule-10 is mostly focused on its clinical efficacy, and few papers are available upon its historical changes. Therefore, we systematically reviewed Sugemule-10 from the aspects of prescription source, prescription interpretation, efficacy evolution, and modern clinical applications.
RESUMO
OBJECTIVE：To establish a method for the content determination of apigenin and piperine in the water extract as well as eucalyptol and cumin aldehyde in the volatile oil of Mongolian medicine Sugmel- 3 decoction. METHODS ：HPLC method was adopted for the content determination of apigenin and piperine. GC method was used for the content determination of eucalyptol and cumin aldehyde. The determination of HPLC method was performed on Agilent Eclipse XDB-C 18 column with mobile phase consisted of methanol- 0.1％ phosphoric acid aqueous solution at flow rate of 1.0 mL/min；the detection wavelength was set at 225 nm（apigenin）and 342 nm（piperine）；the column temperature was set at 30 ℃ with sample size of 10 μL. The determination of GC method was performed on Dimensions SH-Rtx- 1 capillary column with high-purity hydrogen as carrier gas ； the injector temperature was set at 270 ℃，with flow rate of carrier gas 1 mL/min by temperature programmed ；the sample size was 1 μL，and split ratio was 1 ∶ 10. RESULTS：The linear ranges of apigenin ，piperine，eucalyptol and cumin aldehyde were 12.5-200 μg/g/mL（r＝0.999 6），87.3-139.7 μg/mL（r＝0.999 9），136-2 187 μg/mL（r＝0.999 9），39-635 μg/mL（r＝0.999 9）， respectively. The quantitation limits were 0.02，0.06，0.06，0.12 μg/mL，respectively. The detection limits were 0.01，0.02，0.03， 0.04 μg/mL. RSDs of precision，stability and reproducibility tests were all less than 4％. The recovery rates of the samples were 89.26％ -97.26％（RSD＝2.69％ ，n＝6），94.20％ -104.01％（RSD＝3.64％ ，n＝6），98.51％ -110.11％（RSD＝3.87％ ，n＝6）， 95.76％-107.82％（RSD＝4.12％，n＝6），respectively. The contents of above components were 0.769-0.828，7.741-7.981，5.284 7- 5.846 6，1.038 6-1.101 2 mg/g（n＝3）. CONCLUSIONS：The established method is simple and feasible ，and can be used for quality control of different parts of Mongolian medicine Sugmel- 3 decoction.
