Chinese Journal of Primary Medicine and Pharmacy 2011;18(5):624-626
Objective To evaluate the possible auxiliary effect of sipulin in treatment of anthracycline relapsed and metastatic breast cancer. Methods Sixty-three patients were randomly divided into two groups: sipulin group:sipulin plus docetaxel + capecitabine;control group:only administered with docetaxel + capecitabine. The leukocyte, haemoglobin and platelet,toxicity of digestive tract, body weight, Karnofsky status and efficacy of those patients were evaluated respeoively before and after therapy. Results Overall response rates were 71.9% and 54.8% (P = 0.014)for sipulin group and control group, respectively. The median survival time was 15.9 months versus 11.3 months(P=0. 026)for sipulin group and control group,respectively. The 1-year survival rate for sipulin group and control group was 51.6% versus 38.7% (P = 0.035) ,respectively. The clinical efficacy and reduce of leukocyte were better in sipulin group than in control group, the life quality and clinical symptom of the patients in sipulin group were improved more significantly than those in control group (P < 0. 05, P < 0. 01), the value of CD3, CD4, CD3/CD4 and NK in sipulin group were significantly higher than in control group(P < 0.05). Conclusion Sipulin plus docetaxel/capecitabine regimens could improve the efficacy, reduce the toxicities of digestive tract and blood, enhance the immune function and improve life quality, improve the tolerance of relapsed and metastatic breast cancer patients for chemotherapy and should be recommended.

Chinese Journal of General Surgery 1993;0(02):-
Objective To explore the correlation and mechanism between serum adiponectin and estrogen level in female patients with gallstones.Methods A total of 62 female gallstone patients were analyzed,of which 33 cases were premenopausal and 29 cases were postmenopausal.Sixty age-matched normal physical examination cases were selected as controls.Gallbladder stones were diagnosed by B-Ultrasound.Height and weight of the patients were measured to calculate body mass index (BMI).Blood glucose was determined by Glucose Oxidase method.Lipids were determined by turbidimetry method in automatic biochemical analyzer.Serum adiponectin and estrogen were determined by radioimmunoassay.Results Compate with control group,serum adiponectin level was significantly decreased,and estrogen level was significantly ncreased in premenopausal and postmenopausal patients with gallbladder stones.There was a positive correlation between serum adiponectin and HDL-C and ApoA1 level.Conclusions Low serum adiponectin level may be a predisposing factor of gallstone that is initiated by estrogen,and independent of obesity and diabetes.

With development of bio-technique, more and more proteins were applied as clinical approaches. However, the protein homogeneity, especially the N-glycosylation limited the further research and application of these protein drugs. The analysis method for N-glycans is believed to be critical in protein drugs development. To enhance the N-glycans isolation efficiency and accelerate the pretreatment, a new strategy was built on ultrafiltration-devices. New methods increased the isolation efficiency of N-glycans containing N-acetylglucosa mine with 10%-20%. The degrading of N-glycans containing sialic acids was also minimized with this method. 20%-100% more N-glycans with sialic acids were isolated. The pretreatment was finished within 30 min. Coupled with HPLC-HRMS, an effective and reliable strategy designed for protein drugs N-glycans analysis were developed.

OBJECTIVETo optimize the hydrolysis process of linarin by response surface methodology, and to use the model of aldose reductase to study the acacetin's activity of aldose reductase inhibitory.
METHODThe model of acacetin enzyme in vitro was established by the determination of fluorescence absorption of NADPH, the inhibition rate of acacetin aldose reductase was calculated, and then the IC50 of hydrolysis was obtained. The hydrolysis process of linarin hydrolysis condition was optimized by using response surface method.
RESULTThe results indicated that the IC50 of acacetin (2.74 mg x L(-1)) was less than the IC50 of linarin (3.53 mg x L(-1)). Hydrolyzation time of 7.4 h, sulphuric acid concentration of 0.54 mol x L(-1) and the ratio of material to liquid of 3 : 1 were the optimum conditions.
CONCLUSIONHydrolyzate acacetin has preferable inhibitory activity of aldose reductase. The optimized hydrolysis condition of linarin is convenient to use with good predictability.

7. Study of secondary development of Liujing Toutong Tablets
Chinese Traditional and Herbal Drugs 2017;48(20):4145-4150
To study the secondary development of major Chinese materia medica (CMM) varieties is the important content of CMM innovation research, and it is also the important approach of inheriting and developing traditional Chinese medicine (TCM) theory and breaking the bottleneck restricting the development of TCM theory and CMM industry development. In this paper, the secondary development of Liujing Toutong Tablets (LTT) was systematically studied. The chemical components of LTT were elucidated by identification and characterization of herbs, LTT and components ingested into the blood. The main effective components were further screened and cleared by binding experiments of G protein coupled receptors and network pharmacology analysis. The mechanism of LTT was explained by the studies of animal models, isolated organs, cells, functional receptors, and network pharmacology related with headache. The formula features, compatibility regularity were clarified and the action properties, comparative advantages and core clinical value were found and refined by the research of decomposed recipes and the comparison with the similar CMM recipes and chemical drugs. The quality control systems of LTT and related herbs were established by systematic research of identification and characterization of chemical components, the LTT chemical information herbal source, content determination of multi-target ingredients, establishment of the characteristic mode of HPLC fingerprint, sample determination of multiple batches. The original quality standards were promoted comprehensively ensuring the uniformity, stability and controllability of product quality. This study not only provided important theoretical and experimental basis for clinical application and guiding clinical practice, but also provided research ideas and modes for the secondary development of other major CMM.

The quality of Chinese materia medica (CMM) is the lifeline of Chinese medicine industry. However, many problems are still found in the quality study on CMM, which restricts the healthy development of Chinese medicine industry to a certain extent. Aiming at the problems existing in the quality research on CMM, the research idea, method and approach of quality marker research and quality evaluation of CMM were put forward based on systematic analysis and discussion on the basic properties and clinical features of CMM according to the core concept of quality marker and the combination of research practice, from the perspective of transmission and traceability of quality elements, the relationship between chemical composition and traditional efficacy containing "drug property" and "drug function", composition analysis of endemicity based on pharmacophylogenetic study and biosynthetic approach. Finally, a new integrated mode of CMM quality evaluation and control was established.
