OBJECTIVE To explore the causal relationship of circulating cytokines and sensorineural deafness by Mendelian randomization.METHODS Large-scale genome-wide association studies(GWAS)data sets based on UK Biobank were used to identify single nucleotide polymorphisms(SNP)associated with exposure and outcome.The SNP(F>10)significantly associated with exposure data(P<5e-6)and strongly associated with exposure in the F statistic was selected as the instrumental variable for a two-sample Mendelian randomization analysis.The causal effect was estimated using MR-Egger,regression and inverse variance weighting(IVW).Sensitivity analysis was performed to assess the robustness of the results.RESULTS This study confirmed that VEGF(OR=1.04,95%CI:1.01-1.07,P=0.00),SDF-1α(OR=1.10,95%CI:1.02-1.18,P=0.01)and IL-13(OR=1.04,95%CI:1.01-1.06,P=0.01),IL-10(OR=1.06,95%CI:1.02-1.11,P=0.01),IL-7(OR=1.05,95%CI:1.01-1.08,P=0.00)increased the risk of sensorineural deafness.The backward analysis did not find that sensorineural deafness significantly affected the levels of these cytokines.No significant heterogeneity or horizontal pleiotropy was observed among the instrumental variables.CONCLUSION This study reveals a positive correlation between elevated levels of VEGF,SDF-1α,IL-13,IL-10,and IL-7 with sensorineural hearing loss,providing novel targets for further development of biomarkers for the prediction,treatment,and prevention of sensorineural hearing loss.

OBJECTIVE To investigate the effect of gene polymorphism on opioid-induced constipation. METHODS The target genes related to opioid-induced constipation were screened out through searching guidelines， databases and evidence-based medical data， and then 100 cancer pain patients who received opioid drugs for analgesia were included as the study subjects. According to whether there were adverse effects of constipation after medication or not， they were divided into test group and control group， with 50 cases in each group. The target gene was detected by PCR or fluorescence in situ hybridization. The SNPStats program was used to carry out Hardy-Weinberg balance test and correlation analysis between gene polymorphism and opioid-induced constipation. The multivariate Logistic regression analysis was used to explore the relevant predictive factors of opioid-induced constipation， and receiver operating characteristic （ROC） curve of subjects was drawn to analyze the effectiveness of each predictive factor in predicting opioid-induced constipation. RESULTS CYP2D6， CYP3A5*3， ABCB1 and OPRM1 were selected as target genes for detection. The results of genotype detection showed that the frequency distribution of CYP2D6 （rs1065852， rs1135822， rs16947， rs28371725， rs28371735）， CYP3A5*3 （058rs776746）， ABCB1 （062rs1045642）， OPRM1 （047rs1799971） alleles were consistent with Hardy-Weinbergbalance test. The correlation analysis results showed that the proportion of genotype GG and AG in CYP3A5*3 （058rs776746， 163.com A＞G） and genotype AA and AG in OPRM1 （047rs1799971， A＞G） of patients was significantly higher in test group than that in the control group （P＜0.05）. Multivariate Logistic regression analysis showed that medication duration， CYP3A5*3 and OPRM1 gene polymorphism could be used as predictors of opioid- induced constipation in patients （P＜0.05）. The ROC curve analysis results showed that the areas under the ROC curves for medication duration and CYP3A5*3， OPRM1 gene polymorphism were 0.648， 0.640 and 0.670， respectively， with the optimal cutoff values of 124.0， 0.5 and 0.5， respectively. CONCLUSIONS Genotype GG and AG in CYP3A5*3 （058rs776746，A＞G） and genotype AA and AG in OPRM1 （047rs1799971，A＞G） are associated with opioid-induced constipation， which are expected to become clinical predictors of opioid-induced constipation， and more attention should be paid to the occurrence of constipation in patients who have been taking opioids for a long time.

Objective:To explore the functional changes of brain network node information integration and separation in patients with obsessive-compulsive disorder (OCD) and its correlation with clinical symptoms.Methods:Fifty-six patients with obsessive-compulsive disorder (OCD group) and fifty-six healthy controls (control group) matched in gender, age and years of education were enrolled. All participants accepted resting-state functional magnetic resonance imaging scans of the whole brain. Yale-Brown Obsessive Compulsive Scale(Y-BOCS) was used to assess patients′ clinical symptoms. Based on graph theory and independent-sample t-test, the differences in functional network topological properties of nodes between the two groups were analyzed. Partial correlation analysis was used to discuss the relationship between the values of these properties and clinical symptoms. Results:Compared with the control group, the OCD group showed decreased global efficiency and increased shortest path length of the left superior temporal gyrus rostral area and right posterior central gyrus trunk region(both P<0.001, FDR corrected); decreased local efficiency( P=0.002, uncorrected) and clustering coefficient( P<0.001, FDR corrected) of the left inferior frontal gyrus dorsal region. Further analysis showed that the score of the global efficiency of the left superior temporal gyrus rostral area was positively correlated with the score of obsessive thoughts sub-scale ( r=0.390, P=0.005). The score of the shortest path length of the left superior temporal gyrus rostral area was negatively correlated with the obsessive thoughts sub-scale ( r=-0.359, P=0.010) in the OCD group. Conclusion:OCD patients have abnormal information integration and separation functions in the frontoparietal network(inferior frontal gyrus, posterior central gyrus) and abnormal information integration functions in the superior temporal gyrus rostral area. Higher global efficiency and shorter the shortest path length of the superior temporal gyrus rostral area suggest more obsessive thoughts in OCD patients.
