Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a complex genetic disease; the histamine H4 receptor (HRH4) has been shown to be related to different kinds of autoimmune disorders; and copy number variations (CNVs) have been found to be associated with various types of diseases. OBJECTIVES To explore a possible association between HRH4 (formerly H4R) CNVs and the risk of SLE. METHODS Genomic DNA and RNA from 340 patients with SLE and 392 healthy controls were extracted, and CNVs and mRNA levels of HRH4 were examined. RESULTS The expression of HRH4 mRNA was significantly increased in patients with SLE compared with controls. Amplification of HRH4 copy numbers significantly increased the risk of SLE [P < 0·001, odds ratio (OR) 2·26, 95% confidence interval (CI) 1·50-3·40]. HRH4 amplifications also positively correlated with the incidence of arthritis (P = 0·019, OR 1·96, 95% CI 1·11-3·47), and proteinuria (P < 0·001, OR 2·95, 95% CI 1·73-5·00) and antinuclear antibody abnormalities (P < 0·001, OR 2·97, 95% CI 1·66-5·33). Deletions of HRH4 copy numbers were protective against proteinuria (P = 0·03, OR 0·50, 95% CI 0·26-0·94). CONCLUSION CNVs of the HRH4 gene are associated with SLE.

Abstract
BACKGROUND A kinase anchor protein 12 (AKAP12/gravin) belongs to a family of scaffold proteins and organizes protein kinase (PK)A and PKC. DNA hypermethylation in the AKAP12 promoter region has been reported in a variety of human cancers with the exception of skin cancer. Methylation-specific high-resolution melting (MS-HRM) analysis is a novel tool for analysis of promoter methylation. AIM To use MS-HRM analysis to detect the methylation levels of the AKAP12 gene in skin samples. METHODS In total, 195 samples, including basal cell carcinoma, squamous cell carcinoma and actinic keratosis were examined. MS-HRM analysis was used to detect methylation levels of the AKAP12 gene in these samples. RESULTS MS-HRM analysis successfully detected the methylation of AKAP12 in skin samples. The frequencies of AKAP12 methylation in all three types of skin abnormalities were significantly higher than in normal tissues. CONCLUSIONS Application of MS-HRM analysis proved to be a fast and high-throughput method to investigate the epigenetic status of AKAP12. Methylation of AKAP12 can be detected in different skin abnormalities.

Abstract
Systemic lupus erythematosus (SLE) is a complex immune disease. The genetic variation in the PXK gene was found to associate with SLE in Caucasian populations. However, the association of rs6445975 with SLE has not been extensively studied in a Chinese mainland population. A total of 288 SLE patients and 357 controls were recruited. Unlabeled probe-based high-resolution melting analysis (HRMA) was used in genotyping. HRMA with unlabeled probe successfully distinguished all genotypes. Neither genotype nor allele frequencies of SNP rs6445975 showed statistically significant differences between SLE patients and controls. The association of SNP rs6445975 with the diagnostic criteria of SLE was also examined. No obvious association was observed between rs6445975 and the incidence of clinical symptoms. However, the minor allele (G) of rs6445975 was found to significantly associate with increased abnormalities of anti-Smith (p = 0.004, odds ratio (OR) = 1.95, 95% confidence interval (CI) = 1.22-3.09), anti-Ro (p = 0.015, OR = 1.69, 95% CI = 1.10-2.58), anti-La (p = 0.008, OR = 1.86, 95% CI = 1.17-2.93) and C3C4 (p = 0.007, OR = 1.79, 95% CI = 1.17-2.74). Polymorphisms of rs6445975 in the PXK gene were associated with autoantibody production, but not disease risk, of systemic lupus erythematosus in a Chinese population.

Abstract
Activating mutations in B-RAF and N-RAS occur in ∼60 and ∼15% of melanomas, respectively. The most common mutation in B-RAF is V600E, which activates B-RAF and the downstream MEK-ERK1/2 pathway. Thus, B-RAF(V600E) is a viable therapeutic target. PLX4720 is a selective inhibitor of mutant B-RAF and its analog, PLX4032, is currently undergoing clinical trials in melanoma. However, the effects of PLX4720 across the genotypic spectrum in melanoma remain unclear. Here, we describe that PLX4720 treatment rapidly induces hyperactivation of the MEK-ERK1/2 pathway in mutant N-RAS melanoma cells. Furthermore, we demonstrate that C-RAF is the major RAF isoform involved in this process. Importantly, PLX4720-induced hyperactivation of the MEK-ERK1/2 pathway promotes resistance to apoptosis in both non-invasive and invasive mutant N-RAS melanoma cells but does not enhance cell cycle properties. These findings underscore the need to genotypically stratify melanoma patients before enrollment on a mutant B-RAF inhibitor trial.

Abstract
The development of malignant prostate cancer involves multiple genetic alterations. For example, alterations in both survivin and p53 are reported to have crucial roles in prostate cancer progression. However, little is known regarding the interrelationships between p53 and survivin in prostate cancer. Our data demonstrate that the expression of survivin is inversely correlated with that of wtp53 protein (r(s)=0.548) in prostate cancer and in normal prostate tissues. We have developed a therapeutic strategy, in which two antitumor factors, small interfering RNA-survivin and p53 protein, are co-expressed from the same plasmid, and have examined their effects on the growth of PC3, an androgen-independent prostate cancer cell line. When p53 was expressed along with a survivin-specific short hairpin RNA (shRNA), tumor cell proliferation was significantly suppressed and apoptosis occurred. In addition, this combination also abrogated the expression of downstream target molecules such as cyclin-dependent kinase 4 and c-Myc, while enhancing the expression of GRIM19. These changes in gene expression occurred distinctly in the presence of survivin-shRNA/wtp53 compared with control or single treatment groups. Intratumoral injection of the co-expressed construct inhibited the growth and survival of tumor xenografts in a nude mouse model. These studies revealed evidence of an interaction between p53 and survivin proteins plus a complex signaling network operating downstream of the wtp53-survivin pathway that actively controls tumor cell proliferation, survival and apoptosis.

Abstract
This paper discusses a novel artificial anal sphincter with sensor feedback for controlling anal incontinence. The artificial anal sphincter system is a novel hydraulic-electric muscle which mainly comprises an artificial anal sphincter, a wireless power supply subsystem, and a communication subsystem. High integration of all functional components and no wire linking to the outer device make surgical implantation easier and lower risk. The wireless power supply subsystem employs a Class-E power amplifier based on adaptive control technique, and the electromagnetic compatibility in biological tissue is analysed. With the goal of designing a reliable and safe instrument, the models of human colonic blood flow and rectum motion are developed, the biomechanical material properties of human rectum and tissue ischaemia are analysed. The results show that the deformation of the artificial anal sphincter can be controlled by the press of reservoir below the upper limit of human tissue ischaemia. In vitro experiments demonstrate the artificial anal sphincter system is a good cure for human anal incontinence problems.

Abstract
Protocadherins are celladhesion molecules with 6 or 7 cadherin motifs in their extracellular domain and various cyotoplasmic domains. PCDH10 was characterized a novel tumor suppressive gene in and was epigenetically silenced in multiple haematologic malignancies as well as some solid tumors such as gastric cancer, nasopharyngeal carcinoma and esophageal carcinoma. High-resolution melting (HRM) analysis has been used as a novel tool for analysis of promoter methylation. In our study, we used HRM analysis to detect the methylation levels of PCDH10 gene in 100 gastric cancers, 100 colorectal cancers, 70 pancreatic cancers and equal number of adjacent normal tissues. The frequency of PCDH10 methylation in all three types of cancers was significantly higher than that in normal tissues. Consistent with previous reports, expression levels of PCDH10 were inversely correlated with methylation levels. But we didn't find significant association between PCDH10 methylation status and TNM staging in all three types of cancers. In summary, application of HRM analysis to large amount of clinical samples proves to be a fast and high-throughput way to investigate the epigenetic status of PCDH10. And this is the first study to evaluate the prevalence of PCDH10 methylation based on large amount of tumor samples, showing that epigenetic regulation of PCDH10 was associated with carcinogenesis.

Abstract
The potential impact of the surgical correction of strabismus on vision-related quality of life (VRQOL) and the symptoms of anxiety and depression in children with strabismus remain unclear. The present study included 60 children with strabismus: 30 with heterophoria and 30 with heterotropia. A healthy age-and gender-matched control group ( n = 60) was also recruited. The psychological instruments that were used were the short-form 25-item National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25) and the Hospital Anxiety and Depression Scale (HADS). The results demonstrated that eight of the 12 NEI-VFQ-25 subscales were significantly impaired in children with strabismus compared with matched controls. Compared with pre-operative values, significant improvements were noted after surgery in the NEI-VFQ-25 summary score, and the anxiety and depression scores. This study demonstrated that the NEI-VFQ-25 instrument can be used in strabismus children and that surgical interventions can improve VRQOL, anxiety and depression in strabismus patients.

Abstract
e19031 Background: Useful predictors of survival in cancer patients have been found including such as gender, race, age, marital status, state of disease and tumor location. We set to explore the prognostic value of baseline QOL assessments on overall survival in lung cancer patients. Methods: A total of 1,319 lung cancer patients were followed at Mayo Clinic between 1997 and 2007. Overall QOL was assessed by either Lung Cancer Symptom Scale (LCSS) or a single-item Linear Analogue Self Assessment (LASA) with comparable wording. QOL scores were transformed to a 0–100 scale with higher scores representing better status. Patients QOL scores assessed within the first 6 months of follow-up were dichotomized using a priori definition for clinically deficiency score (CDS, ≤50 vs. >50). The Kaplan-Meier method was used to estimate the distribution of survival times by QOL clinical deficient categorization. Cox Proportional Hazards Models were used to evaluate the prognostic importance of QOL on OS alone and in the presence of age, smoking category, gender, treatment, stage of disease, smoking cessation and years of consuming a pack every day. Results: Baseline QOL was significantly associated with OS univariately (HR=0.46 with p<0.0001 based on the CDS categorization). After controlling for all these other factors, the indication of a clinically deficient baseline QOL contributed significantly to the prediction of patient survival (p=0.0002; HR=0.67). Age, treatment, disease stage, smoking cessation and smoking category were also significant predictors of OS multivariately. The median survival for patients that had an overall QOL score less than the CDS (≤50) was 1.6 versus 4.6 years for patients with QOL >50. Conclusions: Baseline overall QOL measured by LCSS or LASA is a significant and independent prognostic factor for OS in lung cancer patients. A meaningful next step in this research is to investigate interventions to improve lung cancer patient QOL and thereby increase their likelihood of survival as well. No significant financial relationships to disclose.
