Purpose: Long non-coding RNA (lncRNA) is identified as an important regulator involved in oral squamous cell carcinoma (OSCC) tumorigenesis. This study aimed to investigate the functional role and underlying mechanism of LINC00662 in OSCC. Materials and Methods: The expression levels of LINC00662, miR-144-3p, and enhancer of zeste homolog 2 (EZH2) mRNA were quantified with quantitative real-time polymerase chain reaction in OSCC tissues and cell lines. Western blot analysis was used to assay the expression levels of E-cadherin, Vimentin, and EZH2. Cell proliferation, migration, and invasion were monitored by cell counting kit-8 and Transwell assays. Dual-luciferase reporter and RNA immunoprecipitation assays were employed to verify the regulatory relationship between LINC00662 and miR-144-3p. Results: The expression of LINC00662, positively associated with the increased TNM stage and lymph node metastasis of the patients, was up-regulated in OSCC tissues and cells. The overexpression of LINC00662 facilitated the proliferation, migration, and invasion of OSCC cells. MiR-144-3p could bind to LINC00662, and the promoting effect of LINC00662 overexpression was counteracted by miR-144-3p mimic. Moreover, EZH2 expression was negatively regulated by miR-144-3p and positively regulated by LINC00662. The silencing of EZH2 attenuated the promoting effects of overexpression of LINC00662 on cell proliferation, migration, invasion, and epithelial-mesenchymal transition. Conclusion LINC00662, as an oncogenic lncRNA of OSCC, accelerates OSCC progression by repressing miR-144-3p expression and increasing EZH2 expression.

OBJECTIVETo detect the anti-FSH antibody using ELISA, and further probe into the role of anti-FSH in infertile patients.

METHODSThe anti-FSH antibody was detected using ELISA in the serum of patients with spermatogenesis dysfunction, of infertile patients with normal sperm density and motility, and of normal fertile males.

RESULTSThe positive rate of anti-FSH antibody in the patients with oligospermia and/or asthenospermia [22.4% (22/98)] was significantly higher than that in the normal fertile [4% (2/50)] (P < 0.05) and that in the infertile patients with normal sperm density and motility [6.7% (2/30)] (P < 0.05). The positive rate of anti-FSH antibody in the patients with oligospermia and/or asthenospermia was lower than that in the patients with azoospermia [54.5% (12/22)] (P < 0.05). There was no significant difference in the positive rate between the normal control and the sterile males with normal sperm density and motility.

CONCLUSIONThe anti-FSH antibody may be an important factor to cause spermatogenesis dysfunction by combining FSH to form immune compound and depress the activation of FSH.

Multiple sclerosis (MS) is a disease characterized as inflammatory demyelinating of the central nervous system,which is the main cause of non-traumatic neurological disability in young and middle-age adults.The main manifestations of MS are memory and information processing speed,executive function and other cognitive impairments.MS associated with memory impairment (MSMI) is often overlooked because of the occult onset,which seriously affecting patients' life quality.In recent years,with the rapid development of neuro-functional imaging,MRI has become an important method to observe and diagnose MS,providing imaging evidence for diagnosis of MSMI.The clinical and MRI research progresses of MEMI were reviewed in this article.

OBJECTIVETo report a true hermaphroditism due to a teragametic chimerism and to discuss the pathogenesis of tetragametic chimerism.

METHODSChromosomal analysis and fluorescence in situ hybridization(FISH) were carried out on the lymphocytes from the blood and on the fibroblasts from the cultured skin and on fibroblasts from two different kinds of gonadal tissues of the patient with ambiguous genitalia respectively. Blood groups, human leukocyte antigen (HLA) haplotyping and 77 short tandem repeat (STR) microsatellite markers were tested. The two kinds of tissues in the gonad were detected by histopathological examination. Blood groups, HLA haplotying and 77 STR microsatellite markers parents of the patient's were also analyzed.

RESULTSEither 46,XX or 46,XY karyotype was found in the lymphocytes of the blood and in the fibroblasts of the cultured skin and of the two different kinds of gonadal tissues. Two X chromosome-specific signals or one X and one Y signal were detected in each interphase nucleus by FISH from the lymphocytes of the blood and the fibroblasts of three different tissue cultures. The karyotype of the 46,XY cell line predominated in all cultures except the cultured-fibroblasts from yellow gonadal tissues. STR marker analysis, ABO grouping and HLA study from the patient were identified a single haplotype in the patient from the mother and two different haplotypes from the father. Two kinds of tissues in the gonad were observed by histopathological examination. The yellow tissue was ovary and the white one was testis.

CONCLUSIONSHistopathological examination and chromosomal analysis combined with FISH are very useful methods for the diagnosis of true hermaphroditism. Blood typing, HLA and short tandem repeat microsatellite markers afford strong evidence for confirming tetragametic chimerism. The mechanism of tetragametic chimerism in true hermaphroditism can be explained by a parthenogenetic division of a haploid nucleu into two identical gametes, followed by fertilization with both X and Y spermatozoa and then developed into an organism.
