RESUMO
Objective:To explore the mechanism of Xijiao Dihuang Ddecoction (XJDHT) against sepsis-induced liver injury based on transcriptomics.Methods:Sixty C57BL/6 mice were randomly (random number) divided into the sepsis group, sepsis treatment with XJDHT and control group, with 20 mice in each group. The sepsis mouse model was established by intraperitoneal (i.p.) injection of lipopolysaccharide (LPS). The control group was intraperitoneally injected with the same amount of normal saline. The sepsis treatment with XJDHT group was injected with XJDHT (crude drug 187.5 mg) twice a day 2 days before modeling. After modeling, gastric feeding was continued twice a day, while the control group and sepsis group were gavaged with the same amount of normal saline. At 72 h after LPS intervention, 9 mice in each group were randomly selected. After anesthesia, part of the liver were taken for small RNA and RNA sequencing and analysis, and part of the liver were taken for pathological examination.Results:XJDHT could improve the histopathological changes of liver in septic mice, and alleviate some abnormally expressed microRNAs (mmu-mir-292a-5p, mmu-mir-871-3p, mmu-mir-653-5p, mmu-mir-293-5p, mmu-mir-155-3p, mmu-mir-346-5p, mmu-mir-187-5p, mmu-mir-3090-3p) and their target genes.Conclusions:XJDHT can reduce the liver histopathological changes in septic mice, and its mechanism may be related to XJDHT regulating the expression of important key genes of liver of sepsis like mmu-mir-187-5p and its target genes such as ADAM8, irak3 and PFKFB3
RESUMO
Sunhe Community Health Service Center is the member of medical partnership of China-Japan Friendship Hospital. According to the real needs of local patients, the center started hemodialysis service on January 2017 with the help of superior partnership hospital. The responsible doctor from the China-Japan Friendship Hospital provided assistance in staff training, facility construction, technical guidance and clinical supervision; and the superior hospital also offered a green channel for patients` referral from the community center. Since starting hemodialysis service with this model, 73 local patients received total 16 768 hemodialyses up to January 2020. During this period 82 patient/times were transferred to superior hospital due to vascular access dysfunction, secondary hyperparathyroidism and other conditions, and referred back after appropriate treatment. This cooperative model makes full use of medical resources and expands the service scope of community health service centers; provides easy access for local chronic renal failure patients, and also improves the clinical capacity of primary care medical staff with sense of professional honor.
RESUMO
Background With the development of refractive surgery,phakic intraocular lens implantation (PIOL) for high myopia is proving its outstanding merits in short-term treating outcomes.However,its long-term safety and effectiveness were still in more attention.Objective This study was to evaluate and compare the long-term safety,stability and efficacy of Verisyse PIOL implantation with implantable contact lens (ICL) implantation for high myopia.Methods The clinical data of 18 eyes (9 patients) who received Verisyse iris-claw intraocular lens implantation for high myopia and matched 22 eyes (11 patients) who received ICL implantation for high myopia from 2009 to 2011 were retrospectively analyzed.The patients were followed-up for 2 years after surgery.Uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),spherical equivalence (SE),axial length,corneal endothelial cell density (ECD),contrast sensitivity (CS),wave-front aberrations and postoperative complications were recorded during the following-up.The efficacy index,predictable and safety index were compared between the two groups.Results There was no significant difference in UCVA,BCVA and SE between Verisyse group and ICL group(t =0.92,1.32,4.32;all at P>0.05).Non-glare CS under the 1.5,3.0,6.0,12.0 and 18.0 c/d spatial frequencies were insignificantly different between the two groups(Z=0.782,0.956,0.495,0.874,0.293;all at P>0.05),and the similar outcomes were found in glare CS (Z=0.985,1.254,0.896,1.652,0.492;all at P>0.05) in postoperative 2 years.Root meas square of total high order aberration (RMSh),vertical-trefoil,vertical-coma,horizontal-coma,spherical aberration(SA),were significantly elevated in the Verisyse group compared with the ICL group (Z =4.72,4.24,3.12,3.65,2.16;all at P < 0.05).The mean efficacy index was 108.49 ± 16.62 in the V erisyse group and 106.71±15.88 in the ICL group,showing a significant difference (t =0.54,P>0.05).The mean safety index was 140.56±33.89 in the Verisyse group and 143.34±34.56 in the ICL group,with a significant difference between them (t=0.29,P>0.05).The mean predictable index was-0.25(-0.97,4.23)in the Verisyse group and 0.98 (-1.44,1.52) in the ICL group,and the difference was significant (Z =-2.68,P < 0.05).Conclusions Both Verisyse PIOL implantation and ICL implantation for high myopia are safe,predictable and effective.The vusial quality and predictability of ICL implantation are much better than Verisyse PIOL implantation.A long-term effect should be observed for the further evaluation.
RESUMO
Aberrant glycosylation is a hallmark of most human cancers and affects many cellular properties, including cell proliferation, apoptosis, differentiation, transformation, migration, invasion, and immune responses. Here, we report that N-acetylgalactosaminyltransferase14 (GALNT14), which mediates the initial step of mucin-type O-glycosylation and is heterogeneously expressed in most breast cancers, plays a critical role in the invasion and migration of breast cancers by regulating the activity of MMP-2 and expression of some EMT genes. We have modulated the expression of GALNT14 by RNAi and overexpression in MCF-7 cells. Overexpression of GALNT14 significantly enhanced cell migration and invasion and promoted the proliferation of breast cancer cells. Knockdown of GALNT14 reduced clonogenicity and attenuates cell migration and cell invasion. The mRNAs for N-cadherin, vimentin, E-cadherin, MMP-2, VEGF, and TGF-ß were determined by RT-qPCR involving GALNT14-overexpressing or knockdown MCF-7 cells. Expression profiling revealed the upregulation of N-cadherin, vimentin, MMP-2, VEGF, TGF-ß and the downregulation of E-cadherin in GALNT14 overexpressing cells, with the opposite seen in GALNT14 knockdowns. Gelatin zymography analysis further indicated that overexpression of GALNT14 increased MMP-2 activity in MCF-7 cells. Conversely, downregulation of GALNT14 reduced MMP-2 activity. Promoter analysis revealed that GALNT14 stimulates MMP-2 expression through the AP-1-binding site. Western blot analyses showed that knockdown of GALNT14 significantly reduced the expression of an oncoprotein mucin 1 (MUC1). These findings indicate that GALNT14 contributes to breast cancer invasion by altering the cell proliferation, motility, expression levels of EMT genes, and by stimulating MMP-2 activity, suggesting GALNT14 may be a potential target for breast cancer treatment.

RESUMO
Objective To observe the expression of survivin and Aurora B in human pancreatic cancer BXPC3 cells after the treatment of sulindac and to explore the potential mechanism. Methods MTr assay was used to determine the effect of sulindac on the proliferation of the BXPC3 cells. RT-PCR was used to detect the expression of mRNA level of survivin and Aurora B, western blot was used to detect protein expression of survivin and Aurora B Thr-232. Cell cycle and apoptosis were detected by flow eytometry (FCM). Results The BXPC3 cells were inhibited by sulindac in a dose and time-dependent manner; the expression of mRNA of survivin and Aurora B were both significantly decreased from 1.5644 and 0.6554 to 0. 4372 and 0.1132 (P< 0.01), the expression of survivin protein and the phosphorylation of Aurora B Thr-232 were also decreased from 1.2735 and 0.4680 to 0.2126 and 0.2546 (P<0.01); the proportion of cells in the G0/G1 phase was increased from (56.65±1.93)% to (70.58±3.21)% (P<0.01). Conclusions Sulindac had inhibitory effects on the growth of BXPC3 cells, the possible mechanism was via decreasing the expression of survivin which depressed the activity of Aurora B, then the CPC was influenced. The most of the cells were blocked in the G0/G1 phase, and the cells' mitosis was inhibited.
