Objective To investigate the course of the mandibular branch of the facial nerve and to discuss its clinical significant in the rhytidectomy. Methods The distribution of the mandibular branch was observed in 30 halves of the fifteen candaveric specimens (ten antiseptic cadaveric specimens and five fresh cadaveric specimens). Results The mandibular branch could be divided into the isolated branch type and shared branch type, after it exited from the parotid gland. 63.33 % mandibular branch was found (2.1?0.7) cm superior to the palpable edge of the mandibular bone; 23.33 % mandibular branch was along the edge of the bone; and 13.33 % was found (1.8?0.5)cm inferior to the palpable edge of the bone. Conclusion The distribution of the mandibular branch locates in the area that is a digit superior and inferior to the lower border of the mandibular bone, which arises from the angle of the mandibular bone. The dissection beneath the SMAS-platysma should be with caution of the injury of the ramification of mandibular branch in the anterior border of the masseter muscle.[

ObjectiveTo study the transcript atlas of cell immunity-associated genes in 8 liver cell types including hepatocytes, bile duct epithelial cells, oval cells, hepatic stellate cells, sinus endothelial cells, Kupffer cells, pit cells and dendritic cells from the rat regenerating liver. Methods The 8 liver cell types were isolated respectively by Percoll density gradient centrifugation combined with immune magnetic beads separation method. Their expression changes in the regenerating livers were detected by Rat Genome 230 2.0 Array, the expression patterns and the predicted physiological activities of cell immunity-associated genes were analyzed by Cluster program, and the methods of bioinformation and systematic biology. Results A total of 40 cell immunity-associated genes yielded the meaningful expression changes in liver regeneration, the corresponding gene numbers in 8 liver cell types were 19, 19, 9, 19, 19, 21, 22 and 21, respectively. It suggested that the formation of antigen peptide-MHC complexes, the NF-κB kinase activity and the production of cytokines like IL-2 were enhanced at the priming and progressing phases of liver regeneration. The biological activities, such as NF-κB-promoting cell differentiation and caspase-induced T cell apoptosis, were elevated at termination phase.Conclusion The rat liver regeneration is associated with cell immunity.

Infectious endophthalmitis refers to the acute suppurative inflammation of the uveal and retinal, with acute onset, severe symptoms, and poor prognosis.Early diagnosis and effective treatment is particularly important.Based on the way of intraocular infection, endophthalmitis can be divided into endogenous endophthalmitis and exogenous endophthalmitis.In the East Asian, liver abscess is the main source of endogenous endophthalmitis, and Klebsiella pneumoniae is the main pathogen.Liver abscess endophthalmitis is a serious cause of blindness caused by intraocular infection.A liver infection disseminated through hematogenous and the primary focus was hidden, which makes the disease was easy to be confused with immune related uveitis, causing high misdiagnosis rate, delaying the best time for diagnosis and treatment.In this article we reviewed the etiology, clinical features, diagnosis and treatment and prognosis of endogenous endophthalmitis caused by liver abscess.Clinicians should maintain a high index of suspicion to the endogenous endophthalmitis caused by liver abscess.

Objective:The different subtypes of voltagE-gated sodium channels (VGSCs) are known to correlate with the migration of many malignant cancers. This study was to investigate the significance of functional expression of SCN5A/Nav1.5 in human ovarian cancer and its effects on migration capability of ovarian cancer cells in vitro. Methods: Sodium indicator SBFI and immunofluorescence method were used to detect the distribution of intracellular Na+. Real-time PCR, Western blotting, and immunohistochemistry were used to detect the mRNA and protein expression of SCN5A/Nav1.5. The effect of specific voltagE-gated sodium channels inhibitor tetrodotoxin (TTX) on cell viability was measured by CCK-8 kit. The migration and invasion of ovarian cancer cell lines SKOV-3 were tested by Transwell chamber assay. Results:SCN5A/Nav1.5 were over-expressed in ovarian cancer cell lines SKOV-3 and ovarian cancer specimens at mRNA and protein levels. TTX 30 μmol/L inhibited the intracellular Na+ concentration by (41.51±0.41)%. TTX also suppressed the invasion and migration capacities of SKOV-3 cells by (33.80±1.6)% and (43.60±2.9)%, respectively. The difference was significant (P<0.05). Conclusion:SCN5A/Nav1.5 is involved in the metastasis progression of ovarian cancer in vitro and plays an important role in the initiation and progression of ovarian cancer. It may become a target for ovarian cancer therapy.
