Objective To detect the plasma amino-terminal pro-B-type natriuretic peptide (NT-ProBNP) of children with congenital heart disease(CHD) prior to heart surgery,to analysize its sensitivity,specificity and Youden index by receiver operating characteristic(ROC) curve,to explore the cut-off values of plasma NTProBNP for the diagnosis of congestive heart failure(CHF) in children under 5 years old before and after age stratification.Method The plasma NT-proBNP was detected for 100 children with CHD prior to heart surgery (experimental group) and 100 normal children(control group) between January 2011 to January 2013.Age stratification(0 ～ 1 year group,～3 years group and ～ 5 year group) was conducted in children with CHF younger than 5 years old to explore the cut-off values of plasma NT-ProBNP for the diagnosis of CHF.Results The NT-proBNP of 34 patients with CHF(n =100) was in accordance to Ross criteria The cut-off values were 502 ng/ L before age stratification,and they were 552 ng/L,449 ng/L,349 ng/L after age stratification for 0 ～ 1 year group,～ 3 years group and ～ 5 group.Conclusion The cut-off values of plasma NT-ProBNP for CHF were 552 ng/L、449 ng/L、349 ng/L for 0 ～ 1 year group,～ 3 years group and ～ 5 year group.

Objective To investigate the effect of hot compress with traditional Chinese herbs with wine and vinegar on lumbago after cesarean section. Methods Ninety patients with lumbago after cesarean section were divided into the control group and the observation group equally according to their admission number. Both groups were cured by the injection at the pressure pain point, the observation group by hot compress of traditional Chinese herbs of Reyanbao with wine and vinegar. The treatment effect between both groups were observed. Results The effective rates of the experiment group and the control group were 93.3%and 68.9%, respectively. The difference was statistically significant (χ2=12.433, P<0.05). Conclusions Based on injection on the pressure pain point, lumbago after cesarean section can be effectively relieved with the extra treatment by hot compress with traditional Chinese herb of Reyanbao with wine and vinegar. The treatment is simple and safe and worthy of being applied clinically.

Objective To establish the HPLC fingerprint for the quality control of Yanhuanglian Injections.Methods HPLC Chromatography method was used.The conditions included a Shim-pack CLC-ODS column(250 mm?6.0 mm,5 ?m),the gredient elution was adopted with acetonitrile-buffer solution(1∶1),the detection wavelength was at 285 nm,and the flow rate was 1.0 mL/min.The Operating Standard of Similarty Evaluation System for Chromatographic Fingerprint of Chinese Materia Medica(Version 2004A)was used to calculate.Results Similarity of 13 batches of injections was over 0.95,the fingerprint of Yanhuanglian Injections was established,and 12 common peaks were indicated.Conclusion This method can be applied to the quality control of Yanhuanglian Injections.

Objective To investigate the expression of Nodal and its receptors in different tissues and organs of different development stages of mice.Methods Ten pairs(male and female each for a pair) of mice were divided into the four groups:3 pairs served as adult mice group,the rest 7 pairs were allowed to mate,among them 3 pregnant mice served as the fetal group,and 3 pregnant mice served as the neonatal group and 1 pregnant mouse served as filial group.The multiple tissues and organs such as brain,liver,kidney,heart,lung were selected from fetal,neonatal,filial and adult mice for preparing the protein samples.Western blot was performed to detect the expression of Nodal and its type Ⅰ receptors of ALK7 and ALK4 as well as auxiliary receptor Cripto-1.Results Only cerebrum,cerebellum,liver and kidney had Nodal express in the four different mouse ontogenetic stages,in which only liver and kidney simultaneously expressed Nodal and its receptor protein in the whole four ontogenetic stages.Besides,most tissues and organs of adult mice expressed Nodal and its receptor protein,which was significantly different from the fetal,neonatal and filial mice.Conclusion Nodal signaling might have a certain effect on the growth and development of mouse liver and kidney during the late development stage.
