AIM:The present study is to observe the effect of Danshen Tablet combined with Simvastatin on hepatic function in patients with hypercholesterolemia.METHODS:Patients with hypercholesterolemia were randomly divided into Simvastatin treatment group(n=20)and Danshen Tablet combined with Simvastatin treatment group(n=20).Before study and after 12 weeks treatment,serum lipid(TC,TG,LDL-C,HDL-C,AST,ALT and CPK)were measured.RESULTS:After treatment,serum lipid in both groups were improved significantly,and there was no difference between them.In Simvastatin treatment group,there was a tendency to increase in ALT and AST,but we could reject at the significant level.In the same way,the serum lipid in combination treatment group decreased,but no statistic difference.Compared with Simvastatin treatment group,ALT and AST in combination treatment group reduced significantly.CPK in both groups did not change.CONCLUSION:Danshen Tablet can reduce liver injury by statin and could serve as an adjuvant in clinical hypolipidemic treatment.

Objective To fabricate rabbit endothelial progenitor cells(EPCs)-seeded stents in vitro and evaluate its feasibility.Methods The mononuclear cells of rabbit were separated by density-gradient centrifugation using lymphocyte isolation.Cells were seeded on fibronectin-coated 6-well plates and maintained on M199 with endothelial cell growth supplements(ECGS,30 ?g/mL).After 2 weeks,cultured cells were identified by immunofluorescence and immunocytochemistry.EPCs proliferation and migration were measured by drawing a growth curve and modified Boyden chamber assay.EPCs adhesion assay was performed by replating EPCs on fibronectin-coated dishes.VEGF and G-CSF were assayed by ELISA while NO was tested by nitrate reductase method.EPCs were poured on fibronectin-coated or uncoated stents.After 6 days,scanning electron microscopy and fluorescence microscopy observation were performed.Results About 14 days after seeding,a majority of spindle-like cells appeared which were characterized as cells,double positive for Dil-acLDL and FITC-UEA-I.EPCs were further confirmed by its expression of the endothelial cell marks of vWF.After 2 weeks culture,EPCs proliferated in exponential growth.They showed high ability of adhesion(96.7?3.2%),migration(15?4) and could secret VEGF,G-CSF and NO.Compared with uncoated stents group,more EPCs migrated and adhered on fibronectin-coated stents group(27.80?4.26 vs 6.10?3.07cells/?400 field,P

Aim To investigate the effects of Shaoqiduogan(SQDG)on cellular immunity in mice with delayed-type hypersensitivity(DTH). Methods DTH model induced by 2, 4-dinitrochlorobenzene(DNCB)and cyclophosphamide(Cy)suppressed and potentiated DTH model were used. SQDG(30, 60 and 120 mg ? kg-1)were given intragastrically(ig)once daily for 7 consecutive days. Concanavalin A(Con A)-induced T cells proliferation was measured by MTT assay. The activity of IL-2 in culture supernatants of Con A-induced T cells proliferation was measured by testing its ability to support the proliferation of Con A stimulated thymocytes which was detected by MTT assay. Results In mice with DTH, SQDG(120 mg?kg-1)reduced ear swelling, thymus index, Con A-induced T cells proliferation and the activity of IL-2 in culture supernatants of Con A-induced T cells proliferation. The suppression and potentiation of DTH in mice were induced by given an intraperitoneal(ip)injection of Cy at the dose of 150mg?kg-1 on primary sensitization day and 250 mg?kg-1 three days before primary sensitization. SQDG(60 and 120 mg?kg-1)upregulated ear swelling, Con A-induced T cells proliferation and the activity of IL-2 in culture supernatants of T cells from mice with Cy-suppressed DTH; and downregulated levels of the aforementioned indexes in mice with Cy-potentiated DTH. Conclusion SQDG possesses a dual modulatory effect on cellular immunity in mice.

Objective:To construct superparamagnetic iron oxide nanoparticles targeting tumor angiogenesis and evaluate their potential value as contrast agent in magnetic resonance imaging (MRI) .Methods:Ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles targeting tumor angiogenesis were prepared by using co-precipitation chemical method. Cyclic RGD(cRGD) containing the sequence of Arg-Gly-Asp were conjugated USPIO nanoparticles by using chemical conjugative method to prepare superparamagnetic imaging agent targeting tumor angiogenic vessles. The physical and chemical properties of cRGD-USPIO nanoparticles were detected. The specific binding capabilities of cRGD-USPIO and USPIO to human lung adenocarcinoma cells (A549) and human umbilical vein endothelial cells (HUVEC) were tested by Prussian blue staining. A549 xenografts were established in nude mice, then USPIO and cRGD-USPIO were injected though tail vein, and the MRI signal enhancement effect of cRGD-USPIO was evaluated.Results:We successfully prepared the cRGD-USPIO nanoparticles. Its core diameter was 5-10 nm and the average diameter was (43.97±10.10) nm and the quality saturation magnetic intensity was 59.94 A·m~2·kg~(-1). Cell-binding test suggested that cRGD-USPIO group showed strengthened positive staining. In vivo MRI experiments showed that signals of tumor were significantly reduced in cRGD-USPIO group than that in USPIO group (P<0.01). Conclusion:The constructed cRGD-USPIO nanoparticles can be developed as a potential tumor-specific MRI contrast agent for the early diagnosis of cancer.

Objective To investigate the level of uncertainty of illness and social support state in patients with prediabetes,and to discuss the correlation between the two.Methods 243 cases with prediabetes were analyzed by Uncertainty in Illness Scale and Social Support Rating Scale.Results There was a middle uncertainty in the elderly patients with prediabetes.The objective support,sabjective support,social support utilization degree and social support score were negatively related to the complexity of uncertainty(r--0.419,-0.433,-0.390 and-0.421,respectively,all P< 0.05).Conclusions Medical staff should evaluate the uncertainty in illness in elderly patients with prediabetes and conduct nursing intervention accordingly,in order to reduce the uncertainty,increase social support,and ultimately improve the quality of life.

Objective The objective of this study was to investigate the expression and clinical significance of transcription factors Sp1 and Survivin in breast cancer and to further analyze their correlation.Methods Seventy cases of breast cancer patients were diagnosed as breast cancer from June 2013 to June 2015.The expression of Sp1 and Survivin in 70 cases of breast cancer and 20 cases of adjacent normal tissues were detected by immunohistochemical staining.The relationship was detected between the protein expression and the clinicopathological parameters of breast cancer.Results The positive rates of Sp1 and Survivin in breast cancer were 71.43% and 78.57%,respectively.The positive rates of Sp1 and Survivin were 30% and 10% in adjacent normal breast tissues.They showed a significant difference(P<0.05).In breast cancer tissues,there were no differences in the lymph node metastasis,TNM stage and vessel infiltration(P>0.05).There were also no differences in the age,tumor size and histological grade of patients with breast cancer(P>0.05).In breast cancer tissues,there was a significant positive correlation between Sp1 and Survivin expression(r=0.517,P<0.01).Conclusion The transcription factors Sp1 and Survivin are closely related to the pathogenesis of breast cancer,which may serve as an adjunctive index for the diagnosis of breast cancer.It has certain guiding value for clinical diagnosis,treatment and prognosis of breast cancer.
