It was found that Ag nanoparticles (NPs) could enhance the chemiluminescence (CL) intensity of luminol- potassium ferricyanide system. On the basis of enhancement effect,a flow injection method was developed for the determination of terbutaline sulfate. The structure and shape of Ag NPs were characterized by transmission electron microscopy. The UV-Vis absorption spectra and chemiluminescence spectra suggested that new luminophor was not formed after Ag NPs introducing in luminol-potassium ferricyanide chemiluminescence system. A possible mechanism of Ag NPs strengthening on luminol-potassium ferricyanide CL reaction was also discussed. The effect of concentration of luminol,potassium ferricyanide,sodium hydroxide and Ag NPs on CL reaction was investigated respectively. In the optimum conditions,the linear range was 1.0×10~(-9) -2.0 ×10~(-5) g/L(r =0.9935) and the detection limit was 1×10~(-10) g/L. The relative standard deviation (RSD) was 3.6% for 1. 0 ×10~(-6) g/L terbutaline sulfate (n = 11 ). The recommended method has been successfully applied to the determination of terbutaline sulfate tablets and the recovery was between 98. 5% - 102. 5% ,moreover the results were almost identical with the same results of Pharmacopoeia method.

Objective To investigate the reproductive endocrine status of women with epilepsy at childbearing age and to systematically analyze the clinical features of reproductive endocrine disorders,especially polycystic ovarian syndrome (PCOS),to facilitate early detection and timely intervention.Methods In this study,scoring of anthropometry and physical signs,menstrul assessment,examination of sex hormone and pelvic ultrasound in women with epilepsy at childbearing age were performed,and the data such as overweight,central obesity,oligo/amenorrhea,luteinizing hormone (LH)/follicule-stimulating hormone (FSH),hyperandrogenism and polycystic ovary (PCO) were collected. The characteristics of their reproductive endocrine hormone disorders were analyzed statistically. Results The age of these patients was (22. 5 ± 7.0 ) years,and women younger than 30 years old and at their peak fertility accounted for 84. 89%. The prevalence rate of PCOS in women with epilepsy at childbearing age (12. 75% ) was significantly higher than that of ordinary women at childbearing age (7.2%) in China.Highly specific indicators for PCOS were hyperandrogenism (100%),LH/FSH ＞ 2 (93%) and oligo/amenorrhea (90%),whilst the highly sensitive indicators for PCOS were PCO (92%), oligo/amenorrhea (85%) and hyperandrogenism (54%). This study revealed statistically significant difference in LH,LH/FSH and testosterone (T) between PCOS group (LH: (10.24 ± 6.92) IU/L; LH/FSH;(2.20 ± 1.16);T: ( 1.07 ± 0. 35) ng/ml) and non-PCOS group ( LH: (4. 16 ± 2.62 ) IU/L; LH/FSH:( 0. 87 ± 0. 56 );T: (0. 46 ±0. 25) ng/ml,t = -3. 899,-4. 240 and -4. 918 respectively,all P ＜0. 01 ). Conclusions Hormone indices are objective indicators for the diagnosis of PCOS. In clinical practice,attention should be paid to height,weight,abodominal circumference,menstrul history and ultrasound examination of the ovary in women with epilepsy.When reproductive endocrine hormone disorders are suspected from clinical features,the sex hormones (T,LH,and FSH ) should be checked to allow timely detection and early interventions.

[Objective]This study was designed to identify the risk factors related with reproductive endocrinology disorder in Chinese women of child-bearing age with epilepsy.[Methods]The clinical data of 102 women with epilepsy were collected.The patient were grouped according to seven aspects(seizure onset age,seizure type,seizure frequency,duration of epilepsy,AED type,age of start AED therapy and duration of therapy)and the contribution of these factors in development of PCOS and its components were analyzed.[Results]The incidence of hyperandrogenemia in the patients with an early onset age(≤14 years old)was higher than the ones with an onset age＞14 years old.Onset age≤14 was the risk factor of hyperandrogenemia in logistic regression analysis.The incidence of a/oligomenorrhea,polycystic ovaries,hyperandrogenemia and PCOS in the valproate-treated women were 40.63%,50.00%,15.65%,and 34.38%,respectively,which were higher than the no-therapy group and nonvalproate treated group.Valproate therapy was the risk factor of PCOS and its components.[Conclusion]Valproate therapy was the risk factor of PCOS and its components in Chinese women of child-bearing age with epilepsy.Onset age≤14 was the risk factor of hyperandrogenemia.

With the development of metabonomics and modern instrumental analysis and bioinformatics, pharmaco-metabonomics has been rapidly put into the diagnosis and treatment of tumor, with a particularly important role in the evaluation and prediction of efficacy, toxicity and resistance of anti-tumor drugs, indivisualized medication and detection of tumor markers. This paper reviews the concept and methodologies of pharmaco-metabonomics, as well as the latest research advances of pharmaco-metabonomics in the diagnosis and freatment of tumors.
