Objective:To study the effects of Anti-DR5 mAb on inducing synovial cells of adjuvant arthritis (AA) rats and its mechanisms.Methods:AA was induced by CFA in rats.The synovial cells of rats were separated and cultured in vitro system.The apoptosis induced by anti-DR5 mAb on synovial cells was measured by MTT analysis,DNA fragmentation and flow cytometry.Caspase-3 and Bcl-2 expression in synovial cells were detected by Western blot.The involvement of the apoptotic pathway was further proved by a caspase inhibition assay.Results:MTT result showed that Anti-DR5 mAb could inhibit synovial cells growth.And flow cytometry suggested that the cell death mode was apoptosis.The protein level of caspase-3 in synovial cells treated with anti-DR5 mAb was raised,while Bcl-2 level declined.When the caspase inhibitor was added to the synovial cells treated with anti-DR5 mAb,it was showed in a dose-dependence inhibition effect,indicating that anti-DR5 mAb inducing apoptosis might be through the caspase pathway.Conclusion:Anti-DR5 mAb could induce synovial cell apoptosis through caspase pathway.And this effect may be related to the protein level of Caspase-3 and Bcl-2.

OBJECTIVE This study aimed at identifying inner ear malformation underlying molecular determinant(s) using a large five-generation Chinese family with multiple familial cases. METHODS Model-based genetic linkage analyses were performed with the use of microsatellite polymorphisms to determine the disease locus. Mutation screening was performed with the family and unrelated population-based controls to establish molecular evidence that caused the specific X-linked inheritance pattern in the family. RESULTS Clinical investigations of the pedigree demonstrated the extremely high penetrance in the male members, but no penetrance in the female members. Linkage analyses mapped the disease to the chromosomal region Xq13.1-Xq23 (maximum X-linkage LOD score = 3.27). Mutation screening of the candidate genes in the linkage region by direct sequencing revealed a de novo missense substitution (925T→C) in the well-known deaf gene POU3F4. Direct sequencing on 110 unrelated controls did not detect any mutation. CONCLUSION a novel mutation of POU3F4 gene was identified to be the causative reason for the hearing loss in family with inner ear malformation.

OBJECTIVE To investigate the contribution of the GJB6 gene [encoding connexin 30 (C?30)] mutations in Chinese population with sporadic non-syndromic hearing impairment. METHODS PCR reactions were performed with two pair of primers for the coding sequence of GJB6 gene and for the deletion of GJB6. PCR products bidirectional sequencing was subsequently applied in 214 patients with hearing loss and 86 normal controls. RESULTS A novel heterozygous mutation-233(C→A) was found, which results in amino acid change, A78D. This mutation wasn't detected in the control subjects. The altered valine residue lies within the second conserved transmembrane domain. The large deletion△(GJB6/ D13S1830)] of GJB6 was not found in this group. CONCLUSION The large deletion of GJB6 was not found in the Chinese deafness population. A novel heterozygous mutation of GJB6 was found. These results indicated GJB6 mutations are not a major cause of hearing loss in the Chinese population.

OBJECTIVETo discuss the feasibility of terminal intestinal exteriorization (exteriorization without ileostomy) in laparoscopic anterior resection for rectal cancer.
METHODSClinicopathological data of 77 patients undergoing laparoscopic anterior resection for low rectal cancer in our department from January 2011 to December 2013 were retrospectively analyzed. After laparoscopic rectal resection, 32 patients received terminal intestinal exteriorization (exteriorization group) and 45 patients received preventive ileostomy (ileostomy group). Anastomosis-related, stoma-related and intestinal stoma closure-related morbidity was compared between the two groups.
RESULTSThere were no significant differences in operative time, blood loss and overall hospital stay between the two groups (all P>0.05). The total hospital cost was (5.39±1.74)×10(4) yuan in the exteriorization group, and (6.98±1.37)×10(4) yuan in the ileostomy group(P<0.01). The incidences of postoperative anastomotic fistula was not significantly different between the two groups(P>0.05). Three patients(9.4%) developed anastomotic leak in the exteriorization group and 2(4.4%) in the ileostomy group. The anastomotic leak was managed by opening the external intestinal wall and maturating an ileostomy under local anaesthesia. All these 5 patients were cured with nutritional support, antibiotics, continuous local drainage. In the exteriorization group, 5 patients had complications related to stoma and intestinal stoma closure operation(15.6%), which was lower than(42.2%) in the ileostomy group(P=0.013).
CONCLUSIONTerminal intestinal exteriorization in laparoscopic anterior resection is a safe and feasible surgical procedure with little trauma and less hospital cost, which can be an alternative as a prophylactic treatment for patients with high risk of anastomotic leak.

Objective To explore the correlation between exon region polymorphism of PPP1R3A gene and schizophrenia in Uygur Chinese population. Methods PPP1R3A gene exon region DNA amplification was performed using multiple PCR targeted capture next-generation sequencing method in 528 patients with schizophrenia and 576 healthy controls of Uyghur descent, Illumina HiSeq X Ten was used for sequencing, the symptoms of schizophrenia were assessed by positive and negative symptoms scale (PANSS). Results The allelic and genotypic distributions in rs1800000 of PPP1R3A gene between patients with schizophrenia and healthy controls had significant difference (P<0.05), rs1799999 in genotype frequency between the female case and control groups showed significant difference (P<0.05). Furthermore, the allelic distributions of rs8192686 between male cases and controls had significant difference (P<0.05). Conclusion PPP1R3A gene rs1800000 may be associated with the development of schizophrenia in Uygur Chinese population; rs1799999 may be a risk factor for susceptibility of female Uygur Chinese schizophrenia; The C allele at rs8192686 may be associated with male Uygur Chinese schizophrenia.
