ABSTRACT
ObjectiveTo investigate the effects of Yishen Daluo prescription （YSDL） on Ras homolog（Rho）/Rho-associated coiled-coil containing protein kinase（ROCK）signaling pathway in mice with experimental autoimmune encephalomyelitis （EAE） based on the silencing of β-arrestin1 gene. MethodSixty C57BL/6 female mice were randomly divided into a blank group， a model group， a virus group， a YSDL group， a virus + YSDL group， and a prednisone acetate group （hormone group）. The EAE model was induced in mice except for those in the normal group. Adeno-associated virus（AAV）solution （150 μL， 1×1011 vg·mL-1） was injected into the tail vein of each mouse in the virus group and the virus + YSDL group on the 4th day of immunization. Drugs were administered on the 8th day of modeling. Specifically， normal saline was given to the mice in the normal group，the model group，and the virus group at 10 mL∙kg-1， prednisone acetate suspension to those in the hormone group at 3.9 g∙kg-1，and YSDL to those in other groups at 20 g∙kg-1 for 14 consecutive days. The mice were weighed and scored every day. The neurological function scores of mice in each group were recorded every day after immunization. Hematoxylin-eosin （HE） staining was used to determine the inflammatory response and lesion location in the brain tissues and spinal cord tissues of mice. The protein expression of β-arrestin1，Ras homolog gene family member A（RhoA）， and Rho-associated coiled-coil forming protein kinase Ⅰ（ROCK Ⅰ） in spinal cord and brain tissues of EAE mice was determined by Western blot. ResultCompared with the model group， the virus group and the virus + YSDL group showed decreased neurological function scores （P<0.01），and the YSDL group also showed decreased neurological function scores（P<0.05）. HE results showed that there was obvious inflammatory reaction in the central nervous system （CNS） of the model group， which was alleviated to varying degrees in other groups compared with the model group. Western blot results showed that compared with the blank group， the model group showed increased protein expression levels of β-arrestin1， RhoA， and ROCK Ⅰ in the spinal cord tissues （P<0.01）. Compared with the model group， the virus group， the YSDL group， the virus + YSDL group， and the hormone group showed decreased protein expression levels of β-arrestin1， RhoA， and ROCKⅠ in the spinal cord tissues （P<0.01）. Compared with the blank group， the model group showed increased protein expression levels of β-arrestin1， RhoA， and ROCK Ⅰ in the brain tissues （P<0.01）. Compared with the model group， the virus group， the YSDL group， the virus + YSDL group， and the hormone group showed decreased protein expression level of β-arrestin1 in the brain tissues （P<0.01）， and the virus group and the YSDL group showed decreased protein expression levels of RhoA， and ROCKⅠ in the brain tissues （P<0.05）. Additionally， the virus + YSDL group and the hormone group showed decreased protein expression levels of RhoA and ROCKⅠ in the brain tissues （P<0.01）. ConclusionYSDL can improve the clinical symptoms of EAE mice and improve the inflammatory response of CNS. The mechanism is presumably attributed to the fact that YSDL inhibits the expression of β-arrestin1 in CNS，thereby reducing the expression of Rho/ROCK signaling pathway. Furthermore， YSDL may have a synergistic effect with the inhibition of β-arrestin1 gene expression.
ABSTRACT
Objective:To investigate the efficacy of Yupingfeng powder combined with extensively hydrolyzed milk formulas in the treatment of milk protein allergy in infants and its effects on immune function, interleukin-10 (IL-10) and IL-22 levels. Methods:Eighty infants with milk protein allergy who received treatment in Hangzhou Children's Hospital from January 2020 to January 2021 were included in this study. They were randomly assigned to Yupingfeng powder and conventional treatment groups, with 40 infants per group. An additional 80 infants who concurrently received health examination in the same hospital were included in the control group. The conventional group was treated with extensively hydrolyzed milk formulas. The Yupingfeng powder group was treated with Yupingfeng powder combined with extensively hydrolyzed milk formulas. All infants were treated for 30 successive days. Clinical efficacy, serum total immunoglobulin (IgE), milk specific IgE (sIgE), peripheral blood CD 4+CD 25+ Treg, IL-10 and IL-22 levels were compared between groups. Results:Total response rate in the Yupingfeng powder group was significantly higher than that in the conventional treatment group [92.50% (37/40) vs. 72.50% (29/40), χ2 = 5.54, P < 0.05]. Serum total IgE and milk sIgE levels in the Yupingfeng powder group were (132.93 ± 14.61) IU/L and (0.62 ± 0.14) IU/L, respectively, which were significantly lower than (150.27 ± 16.22) IU/L and (0.85 ± 0.17) IU/L in the conventional treatment group ( t = 5.02, 6.61, both P < 0.05). The expression of CD 4+CD 25+ Treg in the Yupingfeng powder group was significantly higher than that in the conventional treatment group [(13.29 ± 1.40)% vs. (11.84 ± 1.27)%, t = 4.85, P < 0.05). CD 4+CD 25+ Treg expression in the Yupingfeng powder group was not significantly different from that in the control group [(13.40 ± 2.03)%, t = 0.31, P = 0.759]. IL-10 in the Yupingfeng powder group was significantly higher than that in the conventional treatment group [(34.57 ± 4.07) μg/L vs. (22.19 ± 2.15) μg/L, t = 17.01, P < 0.05]. IL-22 level in the Yupingfeng powder group was significantly lower than that in the conventional treatment group [(2.20 ± 0.42) ng/L vs. (5.28 ± 0.79) ng/L, t = 21.77, P < 0.05]. IL-10 and IL-22 levels in the Yupingfeng powder group were not different from those in the control group [(35.53 ± 3.85) μg/L, (2.13 ± 0.53) ng/L, t = 1.26, P = 0.209; t = 0.73, P = 0.468]. Conclusion:Yupingfeng powder combined with extensively hydrolyzed milk formulas is highly effective on milk protein allergy. The combined therapy can improve the immune function of infants, enhance IL-10 level, and decrease IL-22 level.

BACKGROUND:There is a certain cel subset in esophageal cancer tissues, with certain invasive and metastatic properties, which is closely related to the clinical therapeutic effect on tumors. OBJECTIVE:To isolate tumor stem cel spheres in human esophageal carcinoma cel lines KYSE-150 and TE-1 and to analyze their proliferation and invasion ability. METHODS:KYSE-150 and TE-1 cels were cultured in serum-free medium to observe the formation of cel spheres. Cel proliferation and invasion were detected using MTT and Transwel chamber culture. Surface markers of cels were detected using flow cytometry. RESULTS AND CONCLUSION: Cel spheres that were stably subcultured were obtained from KYSE-150 and TE-1 cels cultured in serum-free medium. The proliferation and invasion abilities of cel spheres were significantly stronger than those of parent cels (P < 0.05). The number of CD44+, CD271+ and CD44+CD271+ cels in TE-1 and KYSE-150 cel spheres was significantly higher than that in the TE-1 and KYSE-150 parent cels (P < 0.05). These experimental results show that cel spheres isolated from human esophageal carcinoma cel lines TE-1 and KYSE-150 have tumor stem cel properties as wel as strong proliferation and invasion abilities. And moreover, CD44 and CD271 can be used as important surface markers of esophageal carcinoma stem cels.
