Objective To measure the levels of serum transferrin receptors (sTfR) and serum ferritin (SF) in children with hemoglobin H disease for investigation the iron metabolism(sideropenic or iron overload) and to guide the proper intervention.To get a best index of judging the iron overload in HbH children by analysis of the values of sTfR and sTfR/lgSF.Methods Peripheral blood specimens were obtained from 50 cases of HbH children and 30 cases of healthy normal controls,the levels of sTfR and SF were examined by enzyme linked immunosorbent assays(ELISA).The diagnosis efficiency of sTfR and sTfR/lgSF in HbH children′s iron metabolism was judged by receiver operator cha-racteristic (ROC) curve analysis.Results The level of sTfR in HbH group was (6.74?1.02) mg?L-1,which was significantly lower than that in healthy control group[(8.09?0.67) mg?L-1](P

Objective: To provide a new manufacturing method for the artificial seeds of Dendrobium officinale. Methods: The artificial seeds were manufactured by taking protocorms of D. officinale as the materials entrapped with the consideration of the effects of testa components and artificial endosperm on the germination and seedling of the artificial seeds. Results: The better conditions of the artificial seeds are manufactured in the fundamental artificial endosperm made by MS + 0.5 mg/L BA + 0.5 mg/L NAA +3 g/L AC + 30 g/L sodium alginate + 3 g/L chlorothalonil mixture reacted in 2% CaCl2 for 15 min; For the higher germination and seedling rate, 15 g/L cassava starch and 10 g/L water retaining agent can be added into the artificial endosperm components, respectively; For the higher germination rate, 10 g/L nano-SiO 2 (better planting rate) and 10 g/L Nano-TiO2 can be added into the artificial testa, respectively. The highest seedling rate was obtained by adding 10 g/L nano-SiO2. Conclusion: A manufacturing method of the artificial seeds of D. officinale has been established for the higher germination and seedling rates.

Forty-two patients with type 2 diabetes (DM group),23 type 2 diabetic patients with unstable angina pectoris (DM + UAP group),and 36 healthy subjects (control group) were enrolled in this study.Serum samples were collected for determining serum concentrations of vascular endothelial growth factor (VEGF),Angiopoietin (Ang)-1,Ang-2,angiogenin,angiostatin,basic fibroblast growth factor,and platelet-derived growth factor-BB using protein array technology.The results showed that there were no significant differences in serum concentrations of all 7 angiogenic factors between control group and DM group.Whereas,serum concentrations of V EGF and Ang-2 were significantly increased in DM + UAP group compared with control group [(3 532.10 ± 1 813.72vs 2 444.50 ± 1 152.21) pg/ml,(286.90-± 217.01 vs 171.92 ± 106.63) pg/ml,both P＜0.01].Pearson's correlation analysis revealed that serum concentrations of all 7 angiogenic factors were not related to HbA1C,fasting and 2 h postprandial plasma glucose,triglycerides,high density lipoprotein cholesterol,as well as low density lipoprotein cholesterol.

Objective To detect the changes in serum concentrations of angiogenic factors in patients with unstable angina pectoris.Methods A total of 57 patients with unstable angina pectoris were eligible for study and divided into diabetes group (n =23) and non-diabetes group (n =34).Exclusion criteria included complicated diseases,symptomatic peripheral vascular diseases,renal or liver diseases,cerebral embolism and evidence of ongoing infection.Another 36 age-matched healthy subjects from medical examination center were enrolled as control group.Serum samples were collected,and serum concentrations of vascular endothelial growth factor (VEGF),angiopoietin-1,angiopoietin-2,angiogenin,angiostatin,basic fibroblast growth factor (bFGF) and platelet-derived growth factor-BB (PDGF-BB) were measured by using cytokine array technology.The data were analyzed by independent-samples t test with the SPSS 13.0statistic software package.Results Compared with the control group,the serum concentrations of VEGF and angiopoietin-2 were significantly increased in patients with unstable angina pectoris (both P ＜ 0.01).Whereas,no significant differences in serum concentrations of angiogenin,angiopoietin-1,angiostatin,bFGF,and PDGF-BB were detected between control group and patient groups.There were no significant differences in serum concentrations of above all 7 biomarkers between diabetes group and non-diabetes group.Conclusions Serum concentrations of VEGF and angiopoietin-2 were increased in patients with unstable angina pectoris,and diabetes didn' t affect the increases in serum concentrations of VEGF and angiopoietin2 caused by unstable angina pectoris.
