To compare the chemical change of Paeoniae Radix Alba (PRA) after vinegar-baking processing, as well as the effect of vinegar types exerted on the processing, 1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to investigate the different metabolites between the raw and two vinegar-baked PRA. More than thirty metabolites were identified in the 1H NMR spectrum of PRA, and the multivariate statistical analysis showed that raw and two vinegar-baked PRA could be separated obviously. After vinegar-baking, the contents of isoleucine, lactate, alanine, arginine, albiflorin, and 5-hydroxymethyl furfural (5-HMF) elevated, while those of sucrose, paeoniflorin and its analogues (calculated by benzoate) decreased. The chemical compositions of two vinegar-baked PRA were also different. Shanxi vinegar- baked PRA showed higher levels of leucine, isoleucine, valine, and albiflorin, while rice vinegar-baked PRA contained more sucrose and paeoniflorin's analogues (calculated by benzoate). And the chemical changes in Shanxi vinegar-baked PRA were greater than those of rice vinegar-baked PRA. The results revealed the chemical differences between raw and vinegar-baked PRA, as well as the influence of vinegar type on processing, in a holistic manner, the results obtained suggested that the correlations between the chemical change and the drug action after processing, as well as the vinegar type used in processing, should be further studied.

Background Refractive lens exchange is one of corrective surgeries for high myopic eyes and is concerned in clinic recently. Its clinical value is worthy of consideration. Objective This study was to investigate the efficacy and safety of refractive lens exchange for high myopic eyes. Methods Phacoemulsification and intraocular lens implantation was performed on 124 eyes of 65 patients with high myopia. The mean age of these patients was 51. 4±8. 57 years old,and the preoperative corrected visual acuity was 4. 11±0. 51. The mean spherical equivalent was ( -20. 17±5. 34) D. The mean axial length was (31. 33±2. 08) mm and intraocular lens power 2. 88 D. The follow-up time was 31 months. The uncorrective visual acuity, best corrective visual acuity, the spherical equivalent lens and complications were observed after operation. Written informed consent was obtained prior to the surgery. Results The uncorrective visual acuity improved after the operation in all the eyes. The uncorrective visual acuity was ≥0.5 in 15 eyes(12% ). The best corrected visual acuity improved in 114 eyes (92% ) following the surgery and that of 64 eyes (51. 6% ) was 2s 0. 5. The mean postoperative spherical equivalent was ( -2. 57 ± 1. 76 ) D in the entire follow-up duration. Posterior capsular opacification was found in 58 eyes (46. 7% ) and received laser capsulotomy. Retinal detachment occurred in 4 eyes throughout the follow-up period. Conclusion Refractive lens exchange is an effective and safe method for high myopic eyes. But preoperative fundus examination and long-term postoperative follow-up should be carried out to prevent the complications.

Astragalus membranaceus var. mongholicus and Hedysarum polybotrys belong to different genera, but have similar drug efficacy in traditional Chinese medicine theory, and H. polybotrys was used as the legal A. membranaceus var. mongholicus previously. In this study, similarities and differences between them were analyzed via their ITS/ITS2 fragments information. The ITS (internal transcribed spacer) regions were amplified using polymerase chain reaction and then sequenced in two-way. The alignment lengths of ITS regions were 616 bp, in which 508 loci were consistent, and 103 loci were different, accounting for 82.47% and 16.72% of the total ITS nucleotides in length, respectively. As genotype determines phenotype, 1HNMR-based metabolomic approach was further used to reveal the chemical similarities and differences between them. Thirty-four metabolites were identified in the 1H NMR spectra, and twenty-seven metabolites were the common components. Amino acids, carbohydrates and other primary metabolites were similar, while a large difference existed in the flavonoids and astragalosides. This study suggests that A. membranaceus var. mongholicus and H. polybotrys show similarities and differences from molecular and chemical perspectives, which has laid a foundation for elucidating the effective material basis of drug with similar efficacy and resources utilization.

Objective To study the supporting role of traditional Chinese medicine GanFuAn in the treatment of high-risk state of liver cancer by color Doppler ultrasound.Methods Based on a number of joint detection of tumor markers,85 patients of liver cancer were selected from patients with chronic hepatitis B.Among these 85patients,50 patients were selected in a treatment group and treated with Chinese herbal preparation GanFuAn,with ultrasound and tumor markers serving as joint monitoring; while the other 35 patients were selected in a control group and treated with conventional treatment.Results In the treatment group,the liver tumor markers or liver tumor continually diminished.5 cases showed tumor disappear.38 cases showed effective results,while 7 cases showed no effects.The total incidence rate of liver cancer was 14％;while in the control group,none case showed tumor disappear.20 cases showed effects and 15 cases showed none effects.The cumulative incidence rate of liver cancer induced by chronic hepatitis was 43％,with all the cases have been confirmed by pathology.Conclusion Color doppler ultrasound was an intuitive,non-invasive dynamic method to monitor liver tumor's growth and decline.

Background and purpose:The incidence of liver cancer is high in China. Primary liver cancers usually occur in patients with liver cirrhosis, which is a challenge for the early diagnosis of liver cancer. Our purpose is to investigate the efifcacy of contrast-enhanced ultrasonography (CEUS) in the early identiifcation and diagnosis of small hepatocellular carcinoma (HCC) by regularly tracking and supervising the high risk population. Methods:A total of 320 high risk patients of HCC admitted in our hospital from February 2011 to November 2013 were enrolled in this prospective study. All patients underwent conventional ultrasound and hepatic CEUS. The differential diagnosis of malignant HCCs from benign ones was based on the enhancement patterns of hepatic lesions in different phases on CEUS. Results:Twenty patients were diagnosed as small HCC among 320 HCC high risk patients who were under regular surveillance using CEUS and all were pathologically conifrmed. Seven of the 20 HCC cases were smaller than 1.0 cm and 13 measured 1.1-2.0 cm. There were 6 (30.0%) HCCs presented as“early wash-in and slow wash-out”atypical pattern of HCC. The small size of the lesion and iso-echogenicity were the main factors of atypical pattern of HCC on CEUS.Conclusion:Ultrasonography and CEUS surveillance is a useful strategy for the early detection of small HCCs in high risk patients, which can help them to receive proper therapeutic management in time.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.
