HPLC fingerprint of Congrong Zonggan capsule was established in order to provide basis for quality evaluation. With acteoside as the reference, HPLC was adopted for fingerprint analysis on Congrong Zonggan capsule. The chromatographic conditions wereas follows. Waters C18 column (4.6 mm x 150 mm, 5 μm) was used, with methylalcohol-0.1% formic acid as the mobile phase for gradient elution at the flow rate of 1.0 mL x min(-1). The detection wavelength was 330 nm, and the column temperature was 30 °C. This method was highly accurate and reproducible. All of the 13 components in tested samples reached the baseline resolved peak, and 15 batches of finished products showed the similarity of above 0.95. The method was accurate and feasible and could be used as a simple and effective method to evaluate the quality of the traditional Chinese medicines.

Objective To analyze the chemical components of Fructus Aurantii (FA) and Fructus Aurantii Immaturus (FAI).Methods HPLC-ESI-MS with Surveg mass spectrometer was used in the study.Chromatographic column: Symmetry Shield TM RP_ 18 (150 mm?3.9 mm, 5 ?m) (Waters, Milford, MA, USA); mobile phase: (A) water (0.6% HAc, pH=2.5), (B) methanol. Gradient elutions: 20%- 40% B (0-48 min); 40% B (48-54 min); 40%-55% B (54-60 min); 55%-95% B (60-75 min); 95% B (75-85 min); 95%-20% B (85-90 min).Flow rate and wavelength were 0.7 mL/min and 283 nm at room temperature, respectively.Results Four kinds of flavonoids were identified as naringin, neohesperidin, naringenin, and hesperidin, synephrine was also identified in FA and FAI. Furthermore, the contents of them were determined individually.The results showed that the chemical constituents in FA and FAI were the same but the contents were different.Conclusion HPLC-ESI-MS method can be efficiently used to study FA and FAI.

Multi-component traditional Chinese medicines are an innovative research mode for traditional Chinese medicines. Currently, there are many design methods for developing multi-component traditional Chinese medicines, but their common feature is the lack of effective connection of the traditional Chinese medicine theory. In this paper, the authors discussed the multi-component traditional Chinese medicine design methods based on medicinal property combination modes, provided the combination methods with the characteristics of traditional Chinese medicine for the prescription combinations, and proved its feasibly with hypertension cases.

This study is to establish an UPLC fingerprint of Resina Draconis from different manufacturers, which can provide a comprehensive evaluation for its quality control. The analysis was performed on a Phenomenex Kinetex 2.6 μ C18 100A column by agradientelution program with acetonitrile-water as mobile phase at a flow rate of 1.7 mL x min(-1). The column temperature was 40 degrees C and the detection wavelengthwas 280 nm. The fingerprints of 18 batches of Draconis Resina were further evaluated by chemometrics methods including similarity analysis (SA), hierarchical clustering analysis (HCA) and principal component analysis (PCA). As a result, there were 15 common peaks, 13 of which had been identified by LC-Q-TOF MS, and the similarity degrees of 15 batches of the samples was more than 0.9, and the samples were divided into 4 clusters by their quality difference. The method is reproducible, simple and reliablethat it can be used for quality control and evaluation of Resina Draconis from different manufacturers.

Objective To acquire some related data of surgical approach through brain superior temporal sulcus to temporal horn of lateral ventricle by MRI volume rendering, and to orientate the point of superior temporal sulcus on the lateral surface which is closest to temporal horn of lateral ventricle,and to find out the best entrance point of surgical approach through superior temporal sulcus to temporal horn of lateral ventricle.Methods 120 adult cases of MRI scanning specimens were chosen for measurement. MRI volume rendering technology was used to rebuild the brain 3D model for the measurement of the full length of superior temporal sulcus S1 .Then cutting along the prependicular to the direction of the long axis of the temporal lobe with 1.0 mm spacings,the coronal sections were obtained,and the distance from superior temporal sulcus to temporal horn of lateral ventricle was ordinally measured and the shortest distance S2 was made sure.And the depth of superior temporal sulcus S3 was detected. The corresponding point on the surface of the brain at superior temporal sulcus according to the point leading the shortest distance S4 was determined. The ratio of S4 to S1 M was calculated. The angle between the shortest distance and median sagittal plane asαwas determined.All the samples were measured on both sides of the brain and all the data were compared.Results The S1 of the 120 cases was (159.56 ± 17.55)mm on the left and (164.35± 15.07)mm on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);the S2 was (8.18±0.96)mm on the left and (7.81±0.90)mm on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);the S3 was (12.19±1.43)mm on the left and (11.57± 1.33)mm on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);the S4 was (100.88±16.09)mm on the left and (104.15±14.49)mm on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);the M was (0.63 ±0.07)on the left and (0.63 ±0.06)on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);theαwas (55.80±3.64)°on the left and (56.46±4.17)°on the right,there was no statistical difference between two cerebral hemispheres(P>0.05). Conclusion The point at the front side 3/5 of superior temporal sulcus may be the ideal surgical approach entrance point.The distance from the point to temporal horn of lateral ventricle is shortest.It indicates that the approach can reduce the damage of brain tissue.

Objective To study clinical significance of anti-momoner C-reactive protein (anti- mCRP) antibody in systemic lupus erythematosus (SLE) and assess the relationship between serum CRP and anti-mCRP antibody.Methods Enzyme-linked immunosorbent assay (ELISA) was applied to determine serum level of anti-mCRP antibody in 113 pateints with SLE,65 patients with other rheumatic diseases,including primary Sjgren syndrome,rheumatoid arthritis,osteoarthritis,ankylosing spondylitis and systemic sclerosis,and 32 healthy controls.Serum level of CRP was evaluated by turbidimetry.Clinical manifestations and laboratory indicators of the patients were all recorded.Results Serum level of anti- mCRP antibody in SLE patients was significantly higher than that in patients with other rheumatic diseases and healthy controls,respectively (t=2.502 and 5.352,respectively,P 0.05).Titer of anti-mCRP antibody closely correlated with systemic lupus erythematosus disease activity index score (r=0.248,P0.05). Conclusions Level of Anti-mCRP antibody increased significantly in patients with SLE,which associated with disease activity of SLE and can be used as a valuable marker in evaluating activity of SLE.

Objective Metabonomics method based gas chromatography-mass spectrometry (GC/MS)were used to analyze the urine samples of patients with hyperlipidemic pancreatitis (HLP) to describe the characteristics of metabolism changes of HLP,identify potential biomarkers,and investigate the role of metabonomics study in the management of AP.Methods 24 patients of HLP and 40 age,sex matched volunteers were enrolled and their urine samples were collected.The urine samples underwent preparation,derivation and GC/MS analysis,Orthogonal-Projection to Latent Structures-Discriminant Analysis (OPLS-DA)were performed to detect the metabolic profile difference between the HLP and control group.Results HLP patients can be precisely distinguished from healthy controls.21 metabolites (credibility > 700 ) were identified using the reference compounds available in the libraries of NIST and Wiley.It was identified that levels of nicotinic acid,aconitie acid,citric acid,hippurie acid,hydroxyphenylacetic acid,hydroxyphenylpropionicacid were decreased,while the levels of tryptophan,tyrosine,tyramine,16-hexadecanoic acid,18octadecanoie acid were increased.It was also suggested that there was change in tricarboxylic acid cycle and gut bacterial flora,as well as fat metabolism and metabolism of amino acid.Conclusions There are differences between healthy controls and HLP patients in the term of GC/MS metabolic profiling,and the biomarkers in the metabolites could be found through metabonomics analysis,and the mechanisms of the metabolic changes could be explored.It was noted that the research of metabolites in the urine samples may be a useful tool to help diagnose and understand the pathogenesis of HLP.Metabonomics analysis is a promising research method.
