AIM: To study the pharmacodynamics of Yajiao Hadun San(Vitex trifolia;streptocaulon griffibhii;Asparagus pseudofilicinus;Inula cappa;Benincasa hispida;Tacca esquirolli). METHODS: The pyrexia model rat induced with active yeast,the mice's auricular swelling test caused by croton oil;the mice's toe swelling test caused by albumen;the mice's twisting body test caused by the irritation of acetic acid and the mice's carbon clearance test were used to determine antipyretic,analgesic,anti-inflammation effect and immunity function of Yajiao Hadun San. RESULTS: Yajiao Hadun San could reduce the anus temperature of the pyrexia model rat,inhibit the mice's toe and auricular swelling,reduce the times of twisting body sharply and also increase the rate of eliminating colloid carbon in mice. CONCLUSION: Yajiao Hadun San has certain antipyretic,anti-inflammation,analgesic effect and enhance the phagocytosis of mono-karyon macrophage in mice.

Objective·To investigate the effects of interleukin-1β (IL-1β) on neonatal rat alveolar arrest induced by intra-amniotic injection of lipopolysaccharide (LPS). Methods·A neonatal SD rat model of bronchopulmonary dysplasia (BPD) was constructed by intra-amniotic injection of LPS in pregnant rats. The pregnant rats (E19) were randomly assigned to Saline group, LPS group and LPS+anti-IL-1β group. The lungs of the neonatal rats were randomly collected 1, 3 and 7 days after birth. Pathological changes in the lungs were observed by hematoxylin-eosin (H-E) staining, and expression of IL-1β mRNA and protein was detected by real-time PCR and ELISA, respectively. Rat bone marrow derived primary macrophage was cultured in vitro, and given LPS intervention, then genes related with IL-1β were detected through whole transcriptome sequencing. Results·Compared with the Saline group, the alveolar counts and secondary septa counts significantly decreased, and mean liner intercept significantly increased in LPS group. Moreover, the expression of IL-1β mRNA and protein in lungs significantly increased in LPS group. The LPS-induced pathological changes of lung tissues in neonatal rats were improved by anti-IL-1β. LPS could up-regulate the expression of genes including Gbp5, Ccl3, Nod2, Ccr5, Mefv, Casp4 and Ifnar1, but down-regulate Lgals9 and Gstp1. Among these genes Gbp5, Ccl3, Nod2, Ccr5, Casp4, Ifnar1 and Lgals9 could positively regulate IL-1βproduction. Conclusion·LPS can induce alveolar arrest through up-regulating the expression of IL-1β in macrophages in neonatal rat BPD model. Whole transcriptome sequencing reveals that LPS can regulate the expression of IL-1β in macrophages through several paths.

OBJECTIVETo compare the effect of citric acid stimulation on salivary alpha-amylase (sAA), total protein (TP), salivary flow rate, and pH value between Pi deficiency (PD) children and healthy children, thereby providing evidence for Pi controlling saliva theory.

METHODSTwenty PD children were recruited, and 29 healthy children were also recruited at the same time. Saliva samples from all subjects were collected before and after citric acid stimulation. The sAA activity and amount, TP contents, salivary flow rate, and pH value were determined and compared.

RESULTS(1) Citric acid stimulation was able to significantly increase salivary flow rate, pH value, sAA activities, sAA specific activity and sAA amount (including glycosylated and non-glycosylated sAA amount) in healthy children (P<0.05), while it could markedly increase salivary flow rate, pH value, and glycosylated sAA levels in PD children (P<0.05); (2) Although there was no statistical difference in determined salivary indices between the two groups (P>0.05), salivary indices except salivary flow rate and glycosylated sAA levels decreased more in PD children. There was statistical difference in sAA activity ratio, sAA specific activity ratio, and the ratio of glycosylated sAA levels between PD children and healthy children (P<0.05).

CONCLUSIONPD children had decreased response to citric acid stimulation.

A HPLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to establish a determination method for drug concentrations of costunolide (Co) and dehydrocostuslactone (De) in blood samples in the positive ion mode, with diazepam as the internal standard substance, in order to study the pharmacokinetic process of sesquiterpene lactones costunolide and dehydrocostuslactone after the oral administration of Weichang'an pills, and provide an theoretical basis for further studies on the substance basis for the anti-diarrhea effect of Weichang'an pills. In the blood samples, Co and De showed a good linearity within concentration ranges 0.700 0-769.7, 2.510-956.0 μg x L(-1), respectively. The results of precision, stability and recovery experiences proved the stability and reliability of the plasma concentration determination method. After the oral administration, the concentrations of Co and De in plasma increased with the increase in dose, with T(max) between 10.65-12.98 h, indicating a long time to reach peak plasma concentrations; C(max) of costunolide and dehydrocostuslactone ranged between 3.750-5.450,15.34-44.52 μg x L(-1), respectively. The in vivo adsorption of Co and De conformed to the one-compartment model, with a longer time to attain the peak plasma concentrations. These results provided an experimental basis for revealing the active substance basis and clinical medication of Weichang'an pills.
