However, few studies have examined the role of m6A in colorectal CRC. To examine the effect of m6A on CRC, we studied the genome of 591 CRC cases from The Cancer Genome Atlas (TCGA). The relationship between the messenger RNA (mRNA) expression, copy number variation (CNVs), and mutations of m6A "Writers," "Readers," and "Erasers," prognosis, immune cell infiltration, and genetic mutations in CRC cases were analyzed. CNVs and mutations were found in thirteen m6A regulators. As expected, gain and amplification of m6A regulators increased the mRNA expression of these regulators, while deletion led to reduction in the mRNA expression. Moreover, CNVs and mutation of these regulators were significantly associated with APC, TP53, and microsatellite instability (MSI) status (p less then 0.001, p less then 0.001, and p = 0.029, respectively). CNVs of m6A regulators also correlated with inferred immune cell infiltration in CRC tissues, especially in colon tissues. Additionally, alterations of RBM15, YTHDF2, YTHDC1, YTHDC2, and METTL14 genes were related to the worse overall survival and disease-free survival (DFS) of CRC patients. Specifically, the deletion status of "Writers" was also correlated to the DFS of CRC patients (p = 0.02). Gene set enrichment analysis found that FTO was involved in mRNA 3' end processing, polyubiquitin binding, and RNA polymerase promoter elongation, while YTHDC1 was related to interferon-alpha and gamma response. In conclusion, a novel relationship was identified between CNVs and mutations of m6A regulators with prognosis and inferred immune function of CRC. These findings will improve the understanding of the relationship of m6A in CRC.
The purpose of this study was to evaluate the effect of repeated autoclave sterilization on the cyclic fatigue resistance of heat-treated NiTi rotary endodontic instruments.

Three NiTi rotary endodontic instruments (EdgeFile X7, EFX7 0.30/0.4; Vortex Blue, VB 0.30/0.4; and TRUShape, TS 0.30/0.6) were selected. Each group (
= 24 each) was divided into 2 subgroups (
= 12 each) sterilized instruments and nonsterilized instruments. The sterilized instruments were subjected to 10 cycles of autoclave sterilization. Twelve instruments from each different subgroups were tested for cyclic fatigue resistance, and the number of cycles to failure (NCF) was calculated. Means and standard deviations were calculated for each group, and data were statistically analyzed using the SPSS program (
< 0.05).

Sterilized and nonsterilized EFX7 files showed the highest NCF compared with other file subgroups. Comparing the results between sterilized and nonsterilized instruments for each type of files, there was a statistically significant difference (
< 0.05) only between sterilized and nonsterilized EFX7 files (1198 versus 755 NCF). selleck chemicals The other instruments did not show significant differences (
> 0.05) in the mean NCF as a result of sterilization cycles (VB, 606 versus 568 NCF; TS, 487 versus 442 NCF).

Repeated cycles of autoclave sterilization increased the NCF of the new heat-treated files, with EFX7 showing statistically significant superior results compared with other files tested.

We prepared PC-DCN nanoliposomes by using rat astrocytes, HSC-T6, to verify the antifibrosis effect of PC-DCN in vitro. First, we established a rat model of carbon tetrachloride-induced fibrosis. PC-DCN nanoliposomes were then injected into fibrotic rats via the portal vein or bile duct. The EdU assay was performed to analyze cell proliferation. Immunofluorescence staining was used to detect α-smooth muscle actin (α-SMA) expression. Western blot was performed to examine the expression of α-SMA, collagen type I alpha 1 (COL1A1), and transforming growth factor-β (TGF-β) protein. The levels of aspartate transaminase (AST), alanine transaminase (ALT), and total bilirubin (TBIL) were examined by enzyme-linked immunosorbent assay (ELISA) analysis. Hematoxylin and eosin (H&E) staining and Masson trichrome staining were used to determine liver tissue lesions and liver fibrosis. Compared with TGF-β group, PC-DCN treatment could significantly reduce cell proliferation. Western blot analysis indicated that the expression of α-SMA, COL1A1, and TGF-β was downregulated after treatment with PC-DCN in vitro and in vivo. Immunofluorescence staining confirmed that α-SMA expression was reduced by PC-DCN. Furthermore, H&E staining and Masson trichrome staining showed that the administration of PC-DCN nanoliposomes via the bile duct could reduce the extent of liver fibrosis. PCR analysis showed that PC-DCN administration could reduce proinflammatory cytokines IL-6, TNF-α, and IL-1β expression via the bile duct. The administration of PC-DCN nanoliposomes also significantly downregulated liver function indicators ALT, AST, and TBIL. The results of our study indicated that PC-DCN could effectively reduce the extent of liver fibrosis.With the aging of the population and the extension of life expectancy, osteoporosis is becoming a global epidemic. Although there are several drugs used to treat osteoporosis in clinical practice, such as parathyroid hormone or bisphosphonates, they all have some serious side effects. Therefore, a safer drug is called for osteoporosis, especially for the prevention in the early stage of the disease, not only the treatment in the later stage. Panax notoginseng saponin (PNS), a traditional Chinese herb, has been used as anti-ischemic drug due to its function on improving vascular circulation. In order to verify whether Panax notoginseng saponins (PNS) could be used to prevent osteoporosis, ovariectomy (OVX) was induced in female C57BL/C6J mice, followed by orally administration with 40 mg/kg/d, 80 mg/kg/d, and 160 mg/kg/d of three different dosages of PNS for 9 weeks. Serum biochemical analysis, micro-CT, histological evaluation, and immunostaining of markers of osteogenesis and angiogenesis were performed in the sham, osteoporotic (OVX), and treatment (OVX+PNS) groups.
