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.

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.

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.

The HPLC fingerprint determination method of Jinzhen oral solution was established to provide a new method for quality control of Jinzhen oral solution. RP-HPLC was used for phenomenex Luna C18 (4.6 mm x 250 mm, 5 μm) chromatographic column, with 0.1% H3 PO4 water solution and acetonitrile as the mobile phase for gradient elution. The detection wavelength was 280 nm. HPLC fingerprint of Jinzhen oral solution was established to identify 17 common peaks in Jinzhen oral solution. The similarity of fingerprints of 10 batches of finished products was more than 0. 90. The established HPLC fingerprint has a better precision, reproducibility and stability, and can be applied in quality control of Jinzhen oral solution.

OBJECTIVETo evaluate the effects of periodontal treatment on the clinical response, systemic inflammatory parameters, and metabolic control of type 2 diabetes patients with moderate to severe periodontitis.
METHODSA total of 56 patients with mean clinical attachment level (CAL)>3 mm were included in the subgroup analysis. A repeated-measures ANOVA (group factor: treatment group and control group; time factor: initial visit, 1.5, 3, and 6 months) was used to analyze the probing depth (PD), CAL, bleeding on probing (BOP), high-sensitivity C-reactive protein (hsCRP), glycated hemoglobin (HbA1c), and fasting plasma glucose.
RESULTSSignificantly lower PD (F=62.898, P-0.000), CAL (F=51.263, P-0.000), BOP (F=75.164, P=0.000), hsCRP (F=6.391, P=0.010), HbA1c(F=4.536, P=0.011), and fasting plasma glucose level (F= 3.073, P=0.031) were observed after therapeutic periodontal improvement. The inter-group differences for PD (t=-2.050, P=0.045), BOP (t=-4.538, P=0.000), and hsCRP (t=-2.261, P=0.028) were statistically significant after therapy.
CONCLUSIONNon-surgical periodontal treatment can effectively improve periodontal status, circulating inflammatory status, and metabolic control of diabetic patients with moderate to severe periodontitis.

Objective We examined the Grp78, ERK1/2 and phospho-ERK1/2 expressions in hepatocellular carcinoma(HCC) tissue samples in vitro, we interfered the expression of Grp78 in SMMC-7721 cells to explore whether Grp78 is involved in ERK1/2 signal pathway. Methods The Grp78, ERK1/2 and phospho-ERK1/2 expressions were detected by immunohistochemistry and confirmed by Western blotting in 47 HCC tissue samples. The Grp78 expression in SMMC-7721 cells was interfered by plasmid transfection and siRNA, ERK1/2 phosphorylation and expression were determined by Western blotting. Results The Grp78 expression was significantly correlated with ERK1/2 and phospho-ERK1/2 in HCC tissue samples. Overexpression of Grp78 promoted ERK1/2 phosphorylation in SMMC-7721 cells and the increased ERK1/2 phosphorylation was inhibited by Grp78 knockdown. Conclusion Grp78 is involved in the regulation of ERK1/2 signal pathway and might be a potential target for the comprehensive therapy of HCC.

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.
