4.Enantiomer Separation and Determination of Amphetamines with Chiral Derivatization by Gas Chromatography-Mass Spectrometry
Chinese Journal of Analytical Chemistry 2001;29(2):182-185
Most drugs of amphetamines contain chiral centers, which form different optical isomers, or enantiomers. Because different enantiomers have different pharmcological effect and have different machnism of metabolism. Besides, the ratio of the two eanatiomers could reflect the route and method used in the synthesis of the drugs. So the separation and determination of these eanantiomers for seizured samples or for biological samples became very important in the sence of forensic science.The paper used two chiral reagents: N-trifluroacetylprolyl chloride (TPC) and ( R )-( + )-α-methoxy-α-(trifluormethyl)phenylacetic acid (MTPA) to reach the purpose. They reacted with amphetamine enantiomers to form diasteromeric pairs, which possess some diffeences in physical and chemical natures and could be separated by GC/MS. The paper examined in detail some fectors such as the solvents, chiral reagent amounts, reaction time,temperature,etc. on the effect of chiral derivatization. Some enantiomers of amphetamine (Am),N-methylamphetamine(MAm),3,4-methylenedioxyamphetamin (MDA), 3,4-methylenedioxy-N-methylamphetamine (MDMA), 3, 4-methylenedioxy-N-ethylamphetamine ( MDEA ) and N-methyl-1-( 3, 4-methylenedioxy )-2-butanamine (MBDB) were well separated each other.
5.Negative Behavior of Preschool Children and Behavior of Their Mothers
Chinese Mental Health Journal 2001;15(1):50-52
Objective: To study the relationship between negative behavior of preschool children and behavior of their mothers. Method.. 742 mothers of children in their 3 ~ 6 year old age were tested by self- made questionnaire. Results: Negative behavior was not significantly related to age and gender of children. It was negatively related to maternal supporting behavior and positively to maternal un- supporting behavior. The culture background (urban/rural), family income and mother' s occupation were found to be important factors mediating maternal un- supporting behavior. Conclusion: Negative behavior of preschool children is influenced by mother' s behavior, which in turn has its cultural - economical background.
6.Role of transcription factors in development of congenital heart disease
International Journal of Pediatrics 2012;39(2):128-131
Congenital heart disease(CHD) is one of the most common birth defects,which is caused by either hereditary or environmental factors,and more commonly by the combination of both.Although CHD is known to be a polygenetic disease,its molecular pathogenesis is still poorly understood.Many genes including the transcription factors have recently been identified to be involved in the development of heart as well as in the pathogenesis of CHD.At the molecular level,this paper reviews the roles of the transcription factors of GATA4/5/6,Nkx2.5,Nkx2.7,TBX1,TBX5,and TBX20,and the interactions among them in the abnormal development of the heart.
7.Related factors and status in prevention and treatment of infant food allergy
International Journal of Pediatrics 2012;39(5):528-532
Food allergy is the earliest and most common allergic disease in infants that affects children' s growth and development.It is closely related to other allergic diseases with a great increase in prevalence.It is important to learn the mechanisms and related factors,investigate the prevention and treatment,and explore the influence to other allergic diseases with food allergy in infants.
8.The influence of mini-invasive evacuation of hematoma for myelin basic protein and neuronspecific enolase in patients with cerebral hemorrhage
Chinese Journal of Postgraduates of Medicine 2012;35(29):22-25
ObjectiveTo observe the influence of mini-invasive evacuation of hematoma for myelin basic protein (MBP) and neuron-specific enolase (NSE) in patients with cerebral hemorrhage.Methods Eighty patients with cerebral hemorrhage were divided into group A and group B by random digits table method with 40 cases each.The patients in group A were given conservation treatment.The patients in group B were given mini-invasive evacuation of hematoma treatment.At the same time 30 cases of healthy people randomly were selected as control group.The serum MBP and NSE were determined before treatment,after treatment 1,3,7,14 d in group A and group B.ResultsThe effective rate in group B was 92.5% (37/40),which was higher than that in group A [80.0%(32/40)],there was significant difference (P < 0.05 ).The serum NSE before treatment in group A and group B was higher than that in control group [ (12.8 ± 2.9),( 13.1 ± 2.8 ) μg/L vs.( 5.3 ± 2.4) μg/L],there was significant difference(P < 0.05 ).The serum NSE after treatment in group B was obviously decreased compared with group A.The serum MBP after treatment 1 d was increased,7 d was decreased,that in group B was obviously decreased compared with group A [ (5.4 ± 1.5) μ g/L vs. (6.9 ± 1.3) μ g/L,P < 0.05 ].ConclusionThe method of mini-invasive evacuation of hematoma in treatment of cerebral hemorrhage patients has good effect,and can decrease the serum MBP and NSE.
9.Steroid-resistant nephrotic syndrome and CD2AP gene
International Journal of Pediatrics 2011;38(5):512-515
Mutations in CD2AP, mapped to 6pL2. 3 and encoding CD2 - associated protein ( CD2AP), are responsible for autosomal recessive or autosomal dominant steroid - resistant nephrotic syndrome (SRNS). CD2AP plays a key role in the slitdiaphragm network of the kidney, which is necessary for the structure and ultrafiltration functions of the slitdiaphragm. The CD2AP homozygous mutation results in early - onset SRNS while heterozygous expression of the CD2AP mutation has increased susceptibility to glomerular injury.No recurrence of proteinuria was observed in the patient with SRNS with CD2AP homozygousmutationafter the renal transplantation. Therefore, detection of the CD2AP gene in the patients suffering from SRNS will be beneficial to making therapeutic decisions and predicting prognoses.
10.Cobalt chloride-induced hypoxia stimulates inflammatory response in adipocytes
Chinese Journal of Endocrinology and Metabolism 2011;27(9):766-769
ObjectiveTo explore the relationship between hypoxia induced by cobalt chloride( CoCl2 ) and inflammation in 3T3-LI adipocytes, and the underlying molecular mechanism. Methods3T3-L1 pre-adipocytes were induced under standard differentiation process. Differentiated 3T3-L1 adipocytes were incubated with CoCl2 to induce hypoxia. The mRNA and protein expressions of hypoxia inducible factor-1 α ( HIF-1 α ), glucose transporter 1 ( Glut1 ), adipocytokines, and inflammatory cytokines, as well as the related signaling pathways were determined with quantitative realtime-PCR and Western-blot in this cell model. ResultsCoCl2 at the concentration of 200 μmol/L significantly up-regulated HIF-1 α and Glut1 expressions. After adipocytes were treated with CoCl2, the mRNA levels of endoplasmic reticulum stress marker genes, such as C/EBP homologous protein (CHOP) and glucose-regulated protein78 (GRP78) were markedly increased, adiponectin mRNA expression was significantly decreased, while resistin and leptin mRNA expressions were significantly increased.In addition, the mRNA expressions of cyclooxygenase 2, interleukin-6, and other inflammatory factors were also increased. The phosphorylation of IκBα,which could inhibit the activation of NF-κB, was stimulated by CoCl2.ConclusionsThe results indicate that hypoxia may induce inflammatory response via NF-κB activiation in adipocytes.
