RESULTS: The calibrated linear curve of entecavir was within 0.033 45～0.167 2 mg?mL-1(r=0.999 98). The average recovery was 100.09%,RSD=0.20%, The content of related substance was 0.54%～1.48%. CONCLUSION: This accurate and reliable HPLC method is applicable for the quality control of entecavir and its related substances.

BACKGROUND:Phytohemagglutinin (PHA) can stimulate the peripheral blood mononuclear cells (PBMCs) into cellcycle, and cause their immune activation, which is a common immune proliferation model. However, the role of non-PBMC ingredient of peripheral blood is unclear, as wel as the expression of endothelial cells related cytokines. OBJECTIVE:To study the effect of whole blood culture and PBMCs alone culture with PHA on the PBMC proliferation and apoptosis, expression of inflammatory cytokine and endothelial cellsecreted cytokine markers. METHODS:Morphological changes of PBMCs separated from normal karyotype human peripheral blood individual y cultured with or without PHA were observed. The PBMCs were col ected by whole blood culture or PBMC separated culture. mRNA was extracted for the fluorescence quantitative RT-PCR, which was applied to detect the cellproliferation, apoptosis, and expression of inflammatory cytokine and endothelial cellsecreted cytokines. The statistic analysis was used for the significance explication. RESULTS AND CONCLUSION:PBMCs alone cultured ere different from those undergoing whole blood culture. The PHA could up-regulate the gene expression of Ki67, proliferating cellnuclear antigen, Caspase 3, interferon-γ, tumor necrosis factor-βand interleukin-6, but down-regulate Protein C. This indicted that PHA could promote the proliferation and apoptosis of PBMCs and up-regulate the expression of inflammatory cytokines, but down-regulate the expression of endothelial cells secreted coagulation cytokines.

OBJECTIVE:To establishment the method for the determination of content of vitamin A palmitate(VAP) and its related substances by HPLC. METHODS:The HPLC conditions were consisted of Phenomenex Luna C18 column with a mobile phase of a mixture of acetonitrile-isopropanol (90∶10) ,the detection wavelength of 328 nm,the column temperature of 30 ℃ and the flow rate of 1.0 mL?min-1. RESULTS:VAP was completely separated from impurities,the linearity range was 90～400 mg?L-1(r=0.999 2). The average recovery rate was 99.60% (RSD=1.32%). The average content of the related substances were lower than 2.53% . CONCLUSION: This accurate and reliable HPLC method is applicable for the quality control of VAP.

Objective To investigate the therapeutic effect of Jianpi Yiqi, Bushen Fenjing combined with oxaliplatin+CF/5-FU on colorectal cancer.MethodsEighty patients with colorectal cancer who were treated in our hospital from January 2014 to December 2015 were randomly divided into observation group(40cases) and control group (40cases).The control group was given oxaliplatin+CF/5-FU treatment, the observation group in the control group based on the application of Spleen Qi, Bushen fill essence treatment, observed before and after treatment of two groups of serum tumor markers, clinical symptoms and living conditions, changes, record adverse reactions.ResultsThe observation effect of 82.50% was significantly higher than that of the control group (62.50%).The QOL score (37.8±5.6) was significantly higher than that of the control group (33.5±3.1) and the adverse reaction rate was 30.00% (P<0.05).The difference between the two groups was significant (P<0.05).ConclusionThe effect of invigorating spleen qi and tonifying siren solution combined with oxaliplatin+CF/5-FU on colorectal cancer can improve the clinical symptoms and improve the quality of life of patients.

This article was aimed to study the acute toxicities on intragastric administration of differentRadix Aconiti Lateralis Praeparataprocessed products to Beagle dogs. A total of 16 healthy and qualified Beagle dogs were randomly divided into the blank group,Pao-Fu-Pian(PFP) group,Pao-Tian-Xiong(PTX) group andHei-Shun-Pian(HSP) group according to the body weight. The intragastric administration of 4 g crude herb per kg was given. Before medication, 1 h, 24 h, and 3, 7, 14 days after medication, the body weight, food consumption, rectal temperature, electrocardiogram, blood routine and blood biochemistry were measured. The results showed that after medication, all dogs in three experimental groups were depressed. And there were significant differences in the electrolytes of blood. Among them, the HSP group was the most obvious one. The red blood cells, blood sugar and triglycerides of dogs in the PFP group had significant difference. The lymphocytes and blood sugar had significant difference of dogs in the PTX group. However, after the medication of HSP, the lymphocytes of the dogs were decreased significantly. It was concluded that the toxicity of three processed products followed the order of HSP > PFP > PTX.

Objective: To explore aspirin resistance (AR) phenomenon in patients with coronary artery disease (CAD) for secondary prevention and to study the relationships between AR and COX1, COX2, TBXA2R gene polymorphisms. Methods: A total of 2881 CAD patients taken aspirin (100 mg/day) in 7 consecutive days were enrolled. Among them, 2 groups were established as AR group, n=166 and Control group, n=200 aspirin sensitive patients. Platelet aggregation function was induced by arachidonic acid (AA), COX1, COX2 and TBXA2R gene polymorphisms were examined by polymerase chain reaction-restricted fragment length polymorphisms (PCR-RFLP) method. Results: The occurrence rate of AR was 5.76% (166/2881). There were 8 tagSNPs locus in 3 genes as in COX1:(rs3842788), (rs4273915), (rs7866582); in: COX2 (rs3218625); in TBXA2R: (rs2238630), (rs2238631), (rs2238633), (rs3786989). The frequencies of wild type, heterozygous genotype and homozygous genotype were similar between 2 groups. Conclusion: The incidence rate of AR is not high in CHD patients with regular aspirin medication; single nucleotide gene polymorphisms of COX1, COX2 and TBXA2R have no obvious correlation to AR.

Objective To investigate the role of and relationship between reactivity to autologous serum and dermatophagoides farinae (Df) in the pathogenesis of chronic urticaria (CU). Methods Autologous serum skin test (ASST) and skin prick test (SPT) to Df were carried out in 831 patients with CU. The correlation between reactivity to autologous serum and Df was statistically analyzed. Results The positivity rate of ASST and SPT to Df was 51.74% and 64.62%, respectively in the 831 patients. SPT was positive in 56.52% of patients with positive ASST and in 73.86% of those with negative ASST (P ＜ 0.05). In patients with positive ASST, the degree of autologous serum reactivity was negatively correlated with that of reactivity to Df (P ＜ 0.05). Conclusions The skin reactivity to Df and autologous serum plays an important role in the pathogenesis of CU, and the degree of the reactivity to Df and autologous serum is negatively correlated. To conduct ASST and SPT simultaneously in patients with CU may favor the clinical classification and therapy of CU.
