Objective To compare the survival and developmental potential of mouse morula, early blastocysts and blastocysts cryopreserved by vitrification. Methods One hundred and forty-two mouse morula, 135 early blastocysts and 148 blastocysts were cryopreserved by 6 mol/L ethylene glycol and 1 mol/L sucrose vitrification solutions. The survival rates and blastocysts hatching rates after thawing were observed. Results The survival rates of morula, early blastocysts and blastocysts groups were 88. 0% ,73. 3% ,and 60. 1% respectively. The blastocyst hatching rates were 73. 9% , 61. 5% ,and 49. 3% respectively. Both the survival rates and blastocyst hatching rates in morula group were higher than those in early blastocysts group (P

ObjectiveTo observe the effect of Qishen Tongluo Zengzhi decoction on cognitive impairment in patients with acute phase of ischemic stroke.Methods A prospective randomized controlled trial was conducted, and 130 patients with acute phase of ischemic stroke and cognitive impairment accompanied by Qi deficiency and blood stasis and stagnationof phlegm-dampness syndrome admitted into the Neurology and Rehabilitation Departments of Rizhao Hospital of Traditional Chinese Medicine(TCM) Affiliated to Shandong University of TCM were randomly divided into treatment group and control group, 65 cases in each group. In the two groups, conventional internal treatment was given to all patients, and in the treatment group, additionally the Qishen Tongluo Zengzhi decoction was administered orally(composition: astragalus membranaceus 30 g, radix pseudostellariae 30 g, notoginseng 10 g,spatholobus stem 25 g, hirudo 3 g, pberetima 10 g, radix paeoniae rubra 12 g, Chinese angelica 12 g, peach kernel 10 g, carthamus tinctorious 10 g, achyranthes 12 g, radix rhapontici 10 g, rhizoma alismatis 6 g, Acorus gramineus Soland 9 g, polygala root 9 g, rhizoma cyperi 10 g, herba siegesbeckiae 15 g),one dose a day. While in the control group, oxiracetam 4.0 g intravenous drip was given, once a day. The whole course was 21 days in both groups. Before and after treatment, the cognitive function of all the patients in two groups was assessed by Mini-Mental State Examination(MMSE)and Montreal Cognitive Assessment(MoCA) scores, and incubation period and amplitude of P300 wave were recorded.Results Finally 62 cases were in treatment group and 63 cases in control group. Before treatment, the comparisons of the MMSE score, MoCA score and P300 latent period and amplitude between the two groups had no statistically significant differences(allP>0.05). After treatment in the two groups, the MMSE score, MoCA score and P300 wave amplitude were elevated, P300 latency period was shortened compared with those before treatment, and the changes were more prominent in treatment group〔score of MMSE: 25.33±2.32 vs. 21.68±2.29, score of MoCA(score): 26.61±3.06 vs. 22.40±2.93, P300 wave incubation period(ms): 349.62±20.01 vs. 371.87±19.63, P300 wave amplitude(μV): 8.70±2.92 vs. 5.72±2.33,allP<0.01〕.ConclusionQishen Tongluo Zengzhi decoctioncan effectively intervene cognitive impairment in patients with acute phase of ischemic stroke, and improve their cognitive function.

Objective Using the weighted gene co-expression network analysis(WGCNA)to explore the key genes of aging associated with Alzheimer's disease(AD).Methods GSE132903 was selected from GEO database as the analysis dataset.The differential expressed genes(DEGs)of AD were screened,and visualized with volcano and heat map.Aging and senescence-associated genes(ASAGs)were downloaded from MsigDB,Aging Altas and CellAge databases.WGCNA screened the gene modules with the highest correlation with AD,and genes of key modules subsequently performed with gene ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis.AD age-related differential expressed genes(ARDEGs)were obtained by taking intersection genes of DEGs,key module genes of WGCNA and ASAGs.Protein-protein interaction(PPI)network analysis was performed using the STRING database to find key node genes.The co-expression networks and associated functions of key genes were analyzed using the GeneMANIA database.The key genes were validated in Alzdata database.Results 226 DEGs,606 ASAGs and 8 ARDEGs were obtained.The top 5 key genes selected by PPI were SYP,STXBP1,VAMP2,CPLX1 and STX1A.Alzdata database verified that the expressions of 5 key genes in other brain regions of AD were down-regulated,except for no significant changes of VAMP2 in hippocampus and STXBP1 in frontal cortex,as well as no expression of CPLX1 in frontal cortex.The differential expression of VAMP2,STXBP1 and STX1A appeared in the early stage of AD,and CPLX1 was related to the pathological process of Tau.SYP and STXBP1 were related to the pathological processes of amyloid β-protein and Tau.Conclusion SYP,STXBP1,VAMP2,CPLX1 and STX1A are ARDEGs,which are expected to be potential diagnostic and therapeutic targets for AD.

Objective:To investigate the role of miRNA-4298/PADI4/p53 signal axis in mediating 4f-induced apoptosis of leukemia cells.Methods:The cell growth density was observed under inverted microscope and the proliferation of leukemia cells was detected by CCK-8 counting assay. The expression of PADI4 and P53 at mRNA level was detected by qRT-PCR. Cell cycle and apoptosis were measured with flow cytometry. The expression of PADI4, P53, Bcl-2, Bax, caspase-3 and caspase-9 at protein level was detected by Western blot. Differential miRNA and mRNA expression profiles was detected by next generation sequencing. Databases such as TargetScan were used to predict the potential upstream and downstream genes of PADI4. A luciferase reporter assay was used to detect the 3′UTR of PADI4 targeted by miRNA-4298. Cell transfection assay was used to detect the effect siRNA, PADI4 vector, miRNA mimics and miRNA inhibitor in interference and rescue.Results:Nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor 4f could inhibit the proliferation of THP-1, K562 and U937 cells, and induce the apoptosis of these leukemia cells. It downregulated the expression of PADI4 mainly through the binding activity of miRNA-4298 to miRNA sponges, which resulted in the proliferation inhibition and apoptosis of leukemia cells. The inhibited proliferation and apoptosis of leukemia cells by 4f were associated with the increase of P53 expression after the decrease of PADI4 expression. The PADI4-dependent upregulation of P53 led to the ratio inversion of downstream Bcl-2/Bax, which activated caspase-3 or caspase-9 to induce the apoptosis of leukemia cells.Conclusions:The apoptosis of leukemia cells induced by Nrf2 inhibitor 4f was mainly associated with the miRNA-4298/PADI4/p53 axis, suggesting that it might be a novel signaling pathway for targeted therapy.
