Methods:The rats were divided into 6 groups with 10 ones in each and fed with special forage for 4 weeks to establish the anorexia model of ju-venile rats. After the model establishment, from the 8th day, the treatment groups received Leshibao chewable tablets respectively at the dose of 0. 60, 0. 30 and 0. 15 g·kg-1 ·d-1 for three weeks. The general situation was observed, and the appetite and body weight were recorded during the treatment. At the end of experiment, the gastric juice amount, free gastric acidity, total gastric acidity and pepsin activity were determined, TP, ALB, TCHO, MTL and GAS were determined by kit methods. Additionally, the mice were given Leshibao chewable tablets at different doses (0. 80, 0. 40, 0. 20 g·kg-1 ·d-1 ) for 7 days, the effects of Leshibao chewable tablets on gastric emptying and intestinal propulsive function were observed. Results: Leshibao chewable tablets could significantly increase the body weight, appetite (P<0. 05 or P<0. 01), gastric juice amount, free gastric acidity , total gastric acidity and pepsin secretion (P<0. 05 or P<0. 01), significantly reduce TP, ALB and TCHO in serum (P<0. 05 or P<0. 01), significantly increase MTL and GAS contents (P<0. 05 or P<0. 01), and significantly promote gastric emptying and intestinal propulsion in mice (P<0. 05 or P<0. 01). Conclusion:Leshibao chewable tablets can significantly increase body weight and appetite, and improve digestive function re-markably, which exhibit excellent therapeutic effect in the anorexia model of juvenile rats.

The content of total lignans in Schisandrae chinensis Fructus was not less than 1. 8% with schizandrin as the standard. Conclusion: The proposed quality evalua-tion standard is more comprehensive and reproducible. It can provide a more scientific evaluation tool for the quality evaluation of Schisandrae chinensis Fructus and its related preparations.

BACKGROUND:The biological behavior of mesenchymal stem cells is influenced by the survival microenvironment.Pre-treatment of the microenvironment is an important means of regulating the function of mesenchymal stem cells. OBJECTIVE:To compare the differences in paracrine function of umbilical cord mesenchymal stem cells and adipose mesenchymal stem cells under oxidative stress and hypoxia,and to provide a theoretical basis for selecting appropriate pretreatment of mesenchymal stem cells to treat different diseases. METHODS:Umbilical cord mesenchymal stem cells and adipose mesenchymal stem cells were cultured by H2O2 or O2 oxygen,respectively,and cell morphology,proliferation,viability and paracrine factor expression were examined. RESULTS AND CONCLUSION:(1)The expression levels of brain-derived neurotrophic factor and transforming growth factor-β were higher in umbilical cord mesenchymal stem cells than in adipose mesenchymal stem cells under a normal culture environment,while the expressions of stromal cell-derived factor-1α and tumor necrosis factor stimulating factor-6 in the adipose mesenchymal stem cells were significantly higher than those in the umbilical cord mesenchymal stem cells.(2)There was no significant difference in the effect of low and moderate levels(≤100 μmol/L)of H2O2 on the viability of the two mesenchymal stem cells.However,increasing the H2O2 concentration from 50 μmol/L to 100 μmol/L resulted in a distinct increase in vascular endothelial growth factor expression in umbilical cord mesenchymal stem cells.The expression of basic fibroblast growth factor,vascular endothelial growth factor,stromal cell-derived factor-1α and interleukin-10 in adipose mesenchymal stem cells was greatly increased by increasing H2O2 concentration in this range.(3)1%O2 hypoxia promoted mesenchymal stem cell proliferation.After 24 hours of culture in 1%O2,gene expression levels were elevated in both mesenchymal stem cells,but the expression levels of vascular endothelial growth factor,interleukin-10 and tumor necrosis factor stimulating factor-6 were significantly higher in adipose mesenchymal stem cells than in umbilical cord mesenchymal stem cells.(4)It is concluded that hypoxia and oxidative stress preconditioning enhances the paracrine function of mesenchymal stem cells.However,mesenchymal stem cells respond differently to hypoxia and oxidative stress.Treating diseases can choose suitable mesenchymal stem cells for appropriate pretreatment to further enhance their therapeutic potential.

Objective To explore the clinical efficacy of ginseng schisandra decoction in children with lobar pneumonia(lung spleen deficiency syndrome)induced by mycoplasma pneumoniae infection and improvement of inflammatory indicators.Method 84 children with lobar pneumonia(lung spleen deficiency syndrome)caused by mycoplasma infection admitted to the First Clinical Hospital of Jilin Academy of Traditional Chinese Medicine from January 2020 to July 2022 were selected and randomly divided into two groups with 42 cases each.The conventional group was treated according to the traditional treatment plan,while the combined group was treated with ginseng and schisandra decoction in addition to the traditional treatment plan.After 7 days,compare the differences in traditional Chinese medicine syndrome scores,clinical efficacy,inflammatory indicators,and total incidence of adverse reactions between the two groups of children.Result The results showed that the traditional Chinese medicine syndrome score and inflammatory indicators in the combined group were lower than those in the conventional group(P<0.05),and the clinical efficacy level distribution was better than that in the conventional group(P<0.05).The total effective rate was higher than that in the conventional group(P<0.05),and there was no difference in the total incidence of adverse reactions between the two groups(P>0.05).Conclusion In the treatment of children with lobar pneumonia(lung spleen deficiency syndrome)caused by Mycoplasma pneumoniae infection,the modified Ginseng Wuweizi decoction has a positive therapeutic effect and good safety,and is worth promoting.

A methodology of quantitative analysis on ginsenoside Re (G-Re) in rat plasma by ultra performance liquid chromatography-triple quadrupole mass spectrometry was developed for comparing the pharmacokinetic profiles between normal rats and Ultraviolet B (UVB) irradiation-induced damage rats after oral administration. The sample separation was carried out on an Ascentis?Express C18column (5.0 mm× 3.0 mm,2.7 μm) with 0.1% formic acid in water and acetonitrile as the mobile phase under gradient elution. MS analysis was operated in multiple-reaction monitoring (MRM) mode using electrospray ionization (ESI) with negative ion mode,and the ions for quantification were m/z 991.54/945.53/475.60. The limit of detection (LOD,S/N=3), limit of quantification (LOQ, S/N=10) were 4.0 ng/mL and 13.5 ng/mL, respectively. G-Re was in good linearity between 15 ng/mL and 20000 ng/mL(r=0.999),the intra-day and inter-day precisions, recovery, matrix effect and stability could meet the pharmacokinetic analysis requirement. The results indicated that the metabolic process of G-Re conformed to a two-compartment pharmacokinetic model after single oral administration in the normal and model groups. The t1/2αwere(0.21± 0.04) h and (0. 69 ± 0. 07) h, respectively; t1/2βwere (17. 08 ± 0. 53) and (21. 40 ± 16. 77) h, respectively;AUC(0-t)were (321.91±2.27) μg/(L·h) and (474.99±194.96) μg/(L·h), respectively;AUC(0-∞)were (332. 44 ± 1. 66) μg/(L·h) and (518. 64 ± 231. 39) μg/(L·h), respectively; the pharmacokinetic parameters were significantly different between normal and UVB irradiated rats (p<0.05), except for t1/2α. This UHPLC-QQQ-MS method showed excellent separation, accuracy, high sensitivity, specificity and good repeatability,and it was suitable for the pharmacokinetic study of G-Re in vivo.
