ABSTRACT

Cisplatin-related ototoxicity is a critical side effect of chemotherapy and can lead to irreversible hearing loss. This study aimed to assess the potential effect of the DNA methyltransferase (DNMT) inhibitor RG108 on cisplatin-induced ototoxicity. Immunohistochemistry, apoptosis assay, and auditory brainstem response (ABR) were employed to determine the impacts of RG108 on cisplatin-induced injury in murine hair cells (HCs) and spiral ganglion neurons (SGNs). Rhodamine 123 and TMRM were utilized for mitochondrial membrane potential (MMP) assessment. Reactive oxygen species (ROS) amounts were evaluated by Cellrox green and Mitosox-red probes. Mitochondrial respiratory function evaluation was performed by determining oxygen consumption rates (OCRs). The results showed that RG108 can markedly reduce cisplatin induced damage in HCs and SGNs, and alleviate apoptotic rate by protecting mitochondrial function through preventing ROS accumulation. Furthermore, RG108 upregulated BCL-2 and downregulated APAF1, BAX, and BAD in HEI-OC1 cells, and triggered the PI3K/AKT pathway. Decreased expression of low-density lipoprotein receptor-related protein 1 (LRP1) and high methylation of the LRP1 promoter were observed after cisplatin treatment. RG108 treatment can increase LRP1 expression and decrease LRP1 promoter methylation. In conclusion, RG108 might represent a new potential agent for preventing hearing loss induced by cisplatin via activating the LRP1-PI3K/AKT pathway.

ABSTRACT

OBJECTIVE@#To diagnose a 46,XN,del(11)(q14q22) fetus by non-invasive prenatal testing (NIPT), karyotype analysis and whole genome sequencing (WGS).@*METHODS@#Peripheral blood sample of the gravida was taken for NIPT screening. Blood samples of the gravida, her husband, and umbilical cord blood were also taken for chromosome karyotyping and whole genome sequencing (WGS).@*RESULTS@#NIPT screening indicated the fetus has carried partial deletion of chromosome 11, while no chromosomal abnormality was found with the cord blood sample due to the low resolution of G-banding analysis. WGS analysis of the cord blood indicated 46,XN,del(11q14.3q22.1). seq[GRCh37/hg19] (90 623 404-97 469 319)×1, 6.85 Mb. The karyotype of the fetus was eventually determined as 46,XN,del(11)(q14q22). Karyotyping analysis suggested that the gravida and her husband were 46,XX,del(11)(q14q22)[8]/46,XX[92] and 46,XY, respectively. However, neither of them was found to harbor the del(11)(q14q22) by WGS.@*CONCLUSION@#The abnormal karyotype of the fetus has derived from its mother's low percentage mosaicism. Combined NIPT, karyotyping analysis and WGS can detect chromosomal disorders with accuracy.

ABSTRACT

Hepatocellular carcinoma (HCC) is one of the five most common malignant tumors. According to the latest statistics of the World Health Organization (WHO), the incident and mortality rates of HCC ranks the eighth and third in the world, respectively, which severely affect people's health. Exosomes are extracellular vesicles with a bilayer of phospholipids, which carry active substances such as proteins and nucleic acids derived from their mother cells. These exosomes greatly facilitate the exchange of substances and information between cells, and coordinate physiological and pathological processes in the body. In recent years, a large number of studies have shown that exosomal proteins play important roles in the tumorigenesis, development, diagnosis and treatment of HCC. Here we review the composition and functions of exosomes and the role of exosomal proteins in HCC.

Morphology and density of microtubule of cells was detected by immunofluorescence assay. (3) The primary cardiomyocytes were grouped and treated as in experiment (2), with 2 wells in each group. The expressions of polymerized microtubulin and free microtubulin were determined with Western blotting. (4) The primary cardiomyocytes were grouped and treated as in experiment (2), with 4 wells in each group. Viability of cells after treated with taxol was detected by MTT method. Data were processed with one-way analysis of variance and LSD-t test.@*Results@#(1) The viability of cells in pH 7.4+ 6 h, pH 7.0+ 6 h, pH 6.5+ 6 h, pH 6.0+ 6 h, pH 6.5+ 1 h, and pH 6.5+ 3 h groups were 1.00±0.08, 0.90±0.08, 0.85±0.06, 0.83±0.04, 0.91±0.10, and 0.89±0.10, respectively. Compared with that in pH 7.4+ 6 h group, viability of cells in pH 7.0+ 6 h, pH 6.5+ 6 h, pH 6.0+ 6 h, pH 6.5+ 1 h, and pH 6.5+ 3 h groups were all decreased in different degrees (t=2.476, 4.002, 4.996, 2.168, 2.400, P<0.05). (2) Microtubules of cells in pH 7.4 group were radially distributed around the nucleus with clear tubular structure. Compared with that in pH 7.4 group, the skeleton of microtubules of cells in pH 6.5 group was obviously damaged, with broken structure of microtubule and reduced density. Compared with that in pH 6.5 group, the damage degree of microtubules of cells in pH 6.5+ taxol group was obviously alleviated, and the structure of microtubules basically returned to normal. (3) Compared with that in pH 7.4 group, the expression of free microtubulin of cells in pH 6.5 group was significantly increased (t=3.030, P<0.05), while the expression of polymerized microtubulin of cells was significantly decreased (t=8.604, P<0.05). Compared with that in pH 6.5 group, the expression of free microtubulin of cells in pH 6.5+ taxol group was significantly decreased (t=4.559, P<0.05), while the expression of polymerized microtubulin of cells was significantly increased (t=5.472, P<0.05). (4) Viability of cells in pH 7.4, pH 6.5, and pH 6.5+ taxol groups were 1.00±0.10, 0.83±0.04, and 0.93±0.10, respectively. Compared with that in pH 7.4 group, the viability of cells in pH 6.5 group was obviously declined (t=4.412, P<0.05). Compared with that in pH 6.5 group, the viability of cells in pH 6.5+ taxol group was obviously increased (t=2.461, P<0.05).@*Conclusions@#The decline of pH value reduces the viability of cardiomyocytes of rats through destroying the skeleton of microtubule. Stabilizing microtubule skeleton can significantly reduce acidic treatment-induced damage and ameliorate cardiomyocyte viability.

Objective To investigate the clinical efficacy of autologous fat transplantation in augmentation mammoplasty with two different methods of purification treatment .Methods Selected 86 patients undergoing autologous fat granule replant mammaplasty .They were randomly and equally divided into the centrifuge group and the static group .After extracting the body fat in the centrifuge group ,obtained the high purity granular fat by using the Centrifugal technique;After the extraction of autologous fat in the static group ,obtain the purified particle fat by using the natural static suspension and physiological saline washed the im‐purities .Respectively ,the processed fat was injected the breast of two groups with multi tunnels and multi layers .After 6 months compared the clinical efficacy of two groups by evaluating the survival rate of autologous fat in augmentation mammoplasty and pre‐operative and postoperative breast volume ,the change of breast shape and patient satisfaction .Results Two groups of patients were successfully completed surgery ,and postoperative wound healed well .After 6 months ,in the centrifuge group and the static group the survival rate of autologous fat was 74 .42 ± 6 .35 and 65 .12 ± 5 .83 (P<0 .05) ,the satisfaction rate was 88 .37% and 76 .74%(P<0 .05) ,respectively .Conclusion The augmentation mammoplasty by injecting autologous fat granules in will not produce im‐mune rejection and surgical scar ,the breast shape is good and can be repeated without satisfactory ,until the desired effect is a‐chieved .The Centrifugal autologous fat can increase the survival rate of fat and patients′satisfaction ,which is suitable for clinical application .
