Yiqi Fumai Lyophilized Injection is a modern preparation composed of Panax ginseng, Ophiopogon japonicas, and Schisandra chinensis. Clinically, it is mainly used for the treatment of cardiovascular diseases such as angina pectoris of coronary heart disease and chronic cardiac insufficiency. According to the concept of quality markers (Q-markers), the Q-markers of Yiqi Fumai Lyophilized Injection were predicted and analyzed from the aspects of chemical components, drug effect, network pharmacology, pharmacokinetics, and drug property. Based on the above studies, 13 components of ginsenosides Rb1, Rg1, Rf, Rh1, Rc, Rb2, Ro, Rg3, ophiopojaponin C, phiogenin-3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside, pennogenin-3-O-α-L-rhamnopyranosyl-(1→2)- β-D-xylopyranosyl-(1→4)-β-D-glucopyranoside, fructose, and schisandrin A were identified as Q-markers. According to the Q-markers, we established quality system for process control. The study of Yiqi Fumai Lyophilized Injection based on Q-markers can provide new research ideas for quality assessment of traditional Chinese materia medica injection.

Quercetin and its glycosides are important flavonols in traditional herbal drugs and plant-derived food, and they have diverse hiological activities such as antioxidant, anticarcinogenic, anti-inflammatory, hypoglycemic and hypolipidemic activities. Numerous studies have demonstrated that quercetin and its glycosides were effective in the prevention and treatment of non-infectious chronic disease such as diabetes, obesity, and hyperlipidemia. They can regulate glucose and lipid metaholism through different mechanisms. They can decrease blood glucose via protecting pancreatic/p cells or/and improving insulin sensitivity. Also, they have lipid-lowering effects, which may be the result of regulation of lipid catabolism or/and anabolism. Their distributions, as well as the hypoglycemic and hypolipidemic effects are reviewed in this paper. In addition, further bioactivities as well as their dose-activity relationship, structure-activity relationship, bioavailability, and future clinical application of quercetin and its glycosides are discussed and proposed.

OBJECTIVETo study the influence of different drying methods on the quality of Schisandrae Chinensis Fructus and thus provide useful reference for its proper drying methods.

METHODSchisandrae Chinensis Fructus was processed by eight drying methods including vacuum freeze drying, natural drying in the shade, drying in the sun, oven drying and vacuum drying under different temperature. The contents of the functional ingredients includes chisandrin, gomisin D, gomisin J, schisandrol B, angeloylgomisin H, angeloylgomisin Q, gomisin G, schisantherin A, deoxyschisandrin, schisandrin B, schisandrin C, 5-HMF, total aids and total sugars. The main components change after drying were analyzed by HPLC, ultraviolet spectrophotometry and potentiometric titration. Principal component analysis (PCA) was carried out by SPSS software to evaluate the quality of different processed products from Schisandrae Chinensis Fructus.

RESULTAll these results are in accordance with the requirements of Chinese Pharmacopoeia published in 2010, the contents of schisandrin and total eleven lignans were the highest using vacuum drying, and 5-HMF were the lower, oven drying made little difference but with lower schisandrin and higher 5-HMF as the heat increased.

CONCLUSIONDifferent drying methods have significant influence on the quality of Schisandrae Chinensis Fructus. Oven drying under 5°C should be adopted to substitute drying in the sun according to the China Pharmacopoeia published in 2010 for Schisandrae Chinensis Fructus by comprehensive analysis of the cost, content and practicality.

The ginsenoside-Ro is sensitive to be hydrolyzed in an alkaline medium. This paper investigated the hydrolysis kinetics of ginsenoside-Ro under different pH and temperature values. The results showed ginsenoside-Ro in alkaline solution followed pseudo-first-order reaction. Hydrolysis kinetics of ginsenoside-Ro has not been reported previously. The hydrolysis rate was independent of initial concentration. On the basis of UFLC-MS/MS, NMR, as well as chemical evidence,the structure of hydrolyzate was assigned as 3-O- [beta-D-glucuronopyranosyl- (1 --> 2) -beta-D-glucopyranosyl] -oleanolic acid.

ObjectiveTo explore the prevalence and spectrum of β-thalassemia mutations in Fujian province,and to provide a reference for prenatal diagnosis and genetic counseling in this population.Methods Two thousand three hundred and one blood samples were randomly selected from 9 different areas of Fujian province from May 2008 to December 2010.PCR and reverse dot blot hybridization (RDB) were adopted for detection of the 17 common types of mutation,and the frequency of each genotype of β-thalassemia mutations was calculated.The β-globin gene of unknown positive samples were analyzed directly with DNA sequencing.Results Three hundred and fifty-nine cases were detected with β-thalassemia mutations of the 2301 copy blood samples submitted,and the detection rate was 15.60％ (359/2301).Of the mutated genes,12 different mutations were identified,namely IVS-2-654(C→T),CD41-42(-TCTT),CD17(A→T),-28(A→G),CD27-28(+C),CD26(G→A),CD71-72(+A),IVS-1-1(G→T),CD43(G→T),-29(A→G),initiation codon ATG→AGG and CD36(-C).Mutation frequencies were 46.54％ (175/376),33.24％ (125/376),9.31％ (35/376),5.05％ (19/376),2.13％(8/376),1.33％(5/376),0.80％(3/376),0.27％(1/376),0.27％(1/376),0.27％(1/376),0.53％(2/376),and 0.27％(1/376),respectively.The most common mutations were IVS-2-654 (C→T) and CD41-42 (-TCTT),which accounted for 79.78％(300/376) of total genetic mutations.In addition,a novel β-globin gene mutation CD36 (-C) allele was detected for the first time,the deletion of a nucleotide C at code 36 within exon 2 lead to a frameshift mutation that could result in a premature termination at code 60.Conclusions β-thalassemia mutations in Fujian province are complex with significant genetic heterogeneity.We present for the first time the detection of a new β-thalassemia mutation in the population:CD36(-C),which provides valuable information for genetic counseling and prenatal diagnosis in Fujian province.

OBJECTIVETo investigate the influences of bicortical anchorage on values of natural frequencies of dental implants utilizing the 3-dimensional finite element analysis.

METHODSUsing the commercial code of Solidworks, 3-D models of a screw-shaped dental implant and a mandibular bone segment were generated. After the 3-D implant-bone complex was meshed by ABAQUS software, effects of bicortical anchorage on the buccolingual and axial first-order natural frequencies of the implant were computed.

RESULTSBicortical anchorage increased both the buccolingual and axial natural frequencies remarkably. As the bicortical anchorage got deeper, the frequencies correspondingly got higher.

CONCLUSIONBicortical anchorage can increase the buccolingual and axial primary stability of dental implants.

OBJECTIVETo study the effect of bitter-cold herbs easing dampness method (BCHEDM) plus Sanhuang Yilong Decoction (SYD) combined with methotrexate (MTX) on expression levels of interleukin-1 (IL-1), IL-6, and IL-17 in rheumatoid arthritis (RA) patients of accumulated dampness-heat syndrome (ADHS).

METHODSFrom January 2011 to January 2013 recruited were 90 RA inpatients of ADHS at Department of Integrative Medicine on Rheumatoid Disease, General Hospital of Chengdu Military Region. They were assigned to the treatment group (45 cases) and the control group (45 cases) according to the random digit table produced by SPSS 11.5 Software. Patients in the treatment group were treated by heavy bitter-cold herbs plus SYD combined with MTX, while those in the control group were treated by MTX alone. Expressional levels of IL-1, IL-6, and IL-17 in serum were detected by enzyme linked immunosorbent assay (ELISA) before treatment, at week 2 and 4 after treatment. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and disease activity score in 28 joints (DAS28) were detected as well.

RESULTSAfter two or four weeks of treatment, ESR, CRP, and DAS28 decreased more in the treatment group than in the control group with statistical difference (P < 0.05, P < 0.01). After four weeks of treatment, IL-1, IL-6, IL-17, ESR, CRP, and DAS28 in the treatment group were all lower than before treatment and those of the control group at corresponding time points with statistical difference (P < 0.01).

CONCLUSIONSYD combined MTX could play roles of improving inflammatory indices within 2 weeks, and inhibiting the expression of IL-1, IL-6, and IL-17 within 4 weeks.
