Objective To investigate the value of the lauromacrogol in sclerosis therapy of endometrial cyst models of SD rat.Methods 45 SD rats were randomly divided into lauromacrogol treatment group,dehydrated alcohol treatment group and physiological saline blank group after being built cysts models.Then corresponding medicine was injected into the cysts,and the changes of pathomorphology and VEGF expression of ectopia endomembrane were observed a week later.Results Microscope observation indicated that endometrial cyst glandular epithelium and gland were inactived by both lauromacrogol and dehydrated alcohol.The effective rate of lauromacrogol group was 87.5％,and that of dehydrated alcohol group was 85.0％.There was no significant difference between these two methods (P =1.000).The ectopia endomembrane glandular organs of physiological saline group were not destructed obviously.Besides,VEGF expression of lauromacrogol and dehydrated alcohol group were lower than physiological saline group (P =0.003 and 0.006).There was no significant difference between VEGF expression of lauromacrogol and dehydrated alcohol group (P =0.926).Conclusions Compared with dehydrated alcohol,lauromacrogol had the same therapeutic effect on sclerosis therapy of endometrial cyst models.

Objective To observe the impacts of Xingnao Kaiqiao acupuncture(AC)method on synaptic plasticity and intestinal flora in stroke rats.Methods The middle cerebral artery occlusion method was applied to establish a rat model of ischemic stroke,and the rats with Zea Longa score of 1-3 were randomly grouped into model(M)group and AC group,and rats without middle cerebral artery occlusion were regarded as the sham(S)group,with 15 animals per group.After modeling,groups S and M were not intervened,and group AC was intervened with AC,once a day,for 7 consecutive days.The Zea Longa method was applied to assess neurological function;transmission electron microscopy(TEM)and Golgi staining were applied to visualize synaptic structures in the ischemic penumbra(IP);Western blot was applied to detect the protein expression of BDNF,SYN and GAP-43 in the IP cortex tissue;ELISA was applied to detect the content of IL-1β,TNF-α,IL-17 in the IP cortex tissue;16S rDNA amplification and sequencing method was applied to analyze the structure of rat intestinal flora.Results Compared with the S group,the M group had irregular synaptic morphology,blurred boundaries,thinned postsynaptic zona densities,higher neurological function scores,protein levels of BDNF,SYN,GAP-43 and content of IL-1β,TNF-α,IL-17(P<0.05),and lower density of spines(P<0.05).Compared with the M group,AC intervention could improve the synaptic morphology,reduce the neurological function score and content of IL-1β,TNF-α,IL-17(P<0.05),and increase the density of dendritic spines,BDNF,SYN,and GAP-43 protein levels(P<0.05).The intestinal flora analysis showed that compared with the S group,the M group had a reduced diversity and number of bacterial flora,at the phylum level,the M group had a lower relative abundance of Bacteroidetes,and higher F/B ratio(P<0.05);at the genus level,the group M had a higher relative abundances of Bacteroides and Rikenbacteria(P<0.05),and lower relative abundances of Lactobacillus and Lachnospiraceae_UCG-006(P<0.05).Compared with the M group,AC intervention could increase the diversity and quantity of the flora,increase the relative abundance of Bacteroidetes and reduce the F/B ratio at the phylum level(P<0.05),increase the relative abundances of Faecalibacterium and Lactobacillus and reduce the relative abundances of Riken,Escherichia-Shigella,etc.at the genus level(P<0.05).Conclusion Xingnao Kaiqiao acupuncture can restore the relative abundance of beneficial bacteria,reduce the relative abundance of harmful bacteria,attenuate brain inflammation,improve synaptic plasticity,and reduce neurological damage in stroke rats.
