Objective: To establish a method for determining the contents of hesperidin and arctiin in the root of Arctium lappa L.from different habitats.Methods: The chromatographic separation was performed on an Acquity UPLC BEH C18 column (50 mm×2.1 mm, 1.7 μm).The mobile phase consisted of acetonitrile (A)-0.1% formic acid (B) with gradient elution at the flow rate of 0.3 ml·min-1.The detection wavelength was 280 nm, and the temperature of column was 25℃.Results: The linear range of hesperidin and arctiin was 4.950-29.700 μg·ml-1 and 6.250-37.500 μg·ml-1(r=0.999 9), respectively.The average recovery of hesperidin and arctiin was 99.0% and 98.5%, respectively.Conclusion: The developed method is sensitive, rapid and accurate, which can be used for the quality control of the root,of Arctium lappa L.

Objective:To explore application and effect evaluation of group prenatal care model in primiparas.Methods:A total of primiparas were recruited from December 2019 to May 2020 in the department of Obstetric clinic. Group prenatal care was carried out in the intervention group and the routine nursing was implemented in the control group. Positive capital Questionnaire and pregnancy outcome were used to evaluate the effects of intervention.Results:The scores of pre-intervention, intervention for one month and post-intervention of PPQ was (123.87±18.86), (130.70±13.41) and (142.23±8.37) respectively. Higher level of natural childbirth rate([86.7%] versus [63.3%]; χ2=4.356; P=0.037<0.05) and lower rate of perineal injury([16.7%] versus [43.3%]; χ2=5.079; P=0.024<0.05). The rate of exclusive breastfeeding during hospitalization ([90.0%] versus [66.7%]; χ2=4.812; P=0.028<0.05) after intervention as compared with those who received routine care. Conclusion:Group prenatal care intervention model can improve the level of positive psychological capital and pregnancy outcome.

Objective To explore the effect of alpha lipoic acid and Shuxuetong on oxidative stress and insulin resistance in patient with type 2 diabetes mellitus(T2DM)and to guide the clinical therapy for T2DM.Methods Totally 90 cases of T2DM pa-tients were sellected from Hainan Province Nongken Hospital.The patients were divided into Shuxuetong group(group A,n=30), alpha lipoic acid group(group B,n=30)and alpha lipoic acid and Shuxuetong group(group C,n =30).HOMA-IR,HOMA-β,and HOMA-ISI was calculated.SOD was determined by xanthine oxidase method.MDA was detected by Thiobarbituric acid method. The expression of IL-6 and TNF-αwas determined by ELISA analysis.Results Before treatment,SOD,MDA,IL-6,TNF-α,HO-MA-IR,HOMA-ISI,and HOMA-βwas no significant difference among the three groups(P >0.05).After treatment,all of which was significantly changed(P <0.05 and P <0.01).SOD,HOMA-ISI and HOMA-βin group C was significantly higher than that in group B(P <0.05),and which was significantly higher in group B than that in group A (P <0.05).MDA and HOMA-IR in group C was significantly lower than that in group B(P <0.05),and which was significantly lower in group B than that in group A (P <0.05).IL-6 and TNF-αin group C was lower than that in group A and group B(P <0.01),and which was no significant difference between group A and group B(P >0.05).Conclusion Alpha lipoic acid combined with Shuxuetong injection can significantly im-prove the oxidative stress state of T2DM patients,inhibit the inflammatory reaction,improve insulin resistance and patient′s sensi-tivity to insulin.Which was contribute to clinical treatment for T2DM.

Objective To evaluate the quality of medicinal materials of Lignum Dalbergiae Odoriferae in Chinese herbal medicine market. Methods Eighteen batches of commercial medicinal materials of Lignum Dalbergiae Odoriferae were identified and analyzed by macroscopical identification, thin layer chromatography (TLC), and volatile oil assay according to the Chinese Pharmacopoeia published in 2010. Visible spectrometry was used to determine the content of total flavonoids from the qualified samples. And the gas chromatography was applied to evaluate the content of nerolidol from volatile oils of the qualified samples. Results Only 33.3%of the samples met the standard of Chinese Pharmacopoeia. The total flavonoid content of the qualified samples was in the range of 21.6-29.0 mg/g. The content of nerolidol from volatile oils of the qualified samples was in the range of 294-574 mg/g. Conclusion At present, the quality of medicinal materials of Lignum Dalbergiae Odoriferae in Chinese herbal medicine market and in clinic varies greatly, and adulterants and inferior are common. The contents of chemical components in different batches of samples are significant different.
