Objective To investigate the changes in the serum level of vascular endothelial growth factor (VEGF) in experimental Wistar rats with hepatic alveolar echinococcosis (HAE) after hepatic arterial infusion (HAI) of bevacizumab treatment, and to discuss the efficacy of HAI of bevacizumab for hepatic alveolar echinococcosis. Methods Forty Wistar rats with successfully established HAE were randomly and equally divided into two groups with 20 rats in each group: the control group and the study group. Hepatic arterial infusion of saline was performed in the rats of the control group , while hepatic arterial infusion of bevacizumab was carried out in the rats of the study group. Before and 7, 14, 21 and 28 days after the treatment peripheral blood samples were collected from the tail vein, and the serum levels of VEGF, apartate aminotransferase (AST) and alanine aminotransferase (ALT) were determined by the quantitative sandwich enzyme-linked immunosorbent assay (ELISA). All the rats were sacrificed 28 days after the treatment. HAE samples were examined to evaluate the effect of bevacizumab on HAE lesions. Results Seven days after hepatic arterial infusion of bevacizumab, serum VEGF expression level in the study group became gradually decreased, and the difference was statistically significant when compared with the preoperative level or with that in the control group (P = 0.019). Fourteen days after the treatment, the serum VEGF expression level kept going down to its lowest point, and the difference in serum VEGF expression level was statistically significant when compared with the preoperative level (P < 0.01). Twenty-one days after the treatment, serum VEGF expression level started to rise and it returned to normal level in 28 days after the treatment. In the control group no significant changes in serum VEGF expression levels was observed after hepatic arterial injection of saline (P > 0.05). Conclusion In treating hepatic alveolar echinococcosis, hepatic arterial infusion of bevacizumab has certain inhibitory effect on angiogenesis. This therapy is safe and effective.

Objective: Study of the results and the degree on occupational noise-induced deafness in-to the different high frequency hearing threshold weighted value, in order to provide theoretical basis for the re-vision of diagnostic criteria on occupational noise-induced deafness. Methods: A retrospective study was con-ducted to investigate the cases on the diagnosis of occupational noise-induced deafness in Guangdong province hospital for occupational disease prevention and treatment from January 2016 to January 2017. Based on the re-sults of the 3 hearing test for each test interval greater than 3 days in the hospital, the best threshold of each frequency was obtained, and based on the diagnostic criteria of occupational noise deafness in 2007 edition, Chi square test, t test and variance analysis were used to measure SPSS21.0 data, their differences are tested among the means of speech frequency and the high frequency weighted value into different age group, noise ex-posure group, and diagnostic classification between different dimensions. Results: 1. There were totally 168 cases in accordance with the study plan, male 154 cases, female 14 cases, the average age was 41.18 ±6.07 years old. 2. The diagnosis rate was increased into the weighted value of different high frequency than the mean value of pure speech frequency, the weighted 4 kHz frequency increased by 13.69% (χ²=9.880, P=0.002) , 6 kHz increased by 15.47% (χ²=9.985, P=0.002) and 4 kHz+6 kHz increased by15.47% (χ²=9.985, P=0.002) , the difference was statistically significant. The diagnostic rate of different high threshold had no obvious differ-ence between the genders. 3. The age groups were divided into less than or equal to 40years old group (A group) and 40-50 years old group (group B) , there were higher the diagnostic rate between high frequency weighted 4 kHz (A group χ²=3.380, P=0.050; B group χ²=4.054, P=0.032) , weighted 6 kHz (A group χ²=6.362, P=0.012; B group χ²=4.054, P=0.032) , high frequency weighted 4 kHz+6 kHz (A group χ²=6.362, P=0.012; B group χ²=4.054, P=0.032) than those of speech frequency average value in the same group on oc-cupational noise-induced deafness diagnosis rate, the difference was statistically significant. There was no sig-nificant difference between age groups (χ²=2.265, P=0.944) . 4. The better ear's mean value of pure speech fre-quency and the weighted values into different high frequency of working years on each group were compared, working years more than 10 years group was significantly higher than that of average thresholds of each frequen-cy band in 3-5 group (F=2.271, P=0.001) , 6-10 group (F=1.563, P=0.046) , the difference was statistically significant. The different high frequency weighted values were higher than those of the mean value of pure speech frequency, and the high frequency weighted 4 kHz+6 kHz had the highest frequency difference, with an average increase of 2.83 dB. 5. The diagnostic rate into weighted different high frequency was higher in the mild, moderate and severe grades than in the pure speech frequency. In the comparison of diagnosis for mild occupational noise-induced deafness, in addition to the weighted 3 kHz high frequency (χ²=3.117, P=0.077) had no significant difference, the weighted 4 kHz (χ²=10.835, P=0.001) , 6 kHz (χ²=9.985, P=0.002) , 3 kHz+4 kHz (χ²=6.315, P=0.012) , 3 kHz+6 kHz (χ²=6.315, P=0.012) , 4 kHz+6 kHz (χ²=9.985, P=0.002) , 3 kHz+4 kHz+6 kHz (χ²=7.667, P=0.002) were significantly higher than the diagnosis rate of the mean value of pure speech frequency. There was no significant difference between the two groups in the moderate and se-vere grades (P>0.05) . Conclusion Bring into different high frequency hearing threshold weighted value in-creases the diagnostic rate of occupational noise-induced deafness, the weighted 4 kHz, 6 kHz and 4 kHz+ 6 kHz high frequency value affects the result greatly, and the weighted 4 kHz+6 kHz high frequency hearing threshold value is maximum the effect on occupational noise-induced deafness diagnosis.

Objective To use cluster analysis to explore the clinical phenotypes of Synovitis-Acne-Pustulosis-Hyperostosis-Osteitis (SAPHO) syndrome.Methods One hundred and sixty-four patients fulfilled the Kahn and Khan's criteria for SAPHO syndrome were recruited in Peking Union Medical College Hospital from 2004 to 2015.For all patients,demographics,clinical,laboratory and imaging data were collected.Cluster analysis was performed using an iterative partitioning K-means method including 11 variables that was most characteristic in patients with SAPHO syndrome.The optimal number of clusters was determined by the elbow method and Silhouettes coefficient in combination with clinical significance.Results An optimal of two phenotypes with distinct clinical features were identified.Cluster 1 was characterized by axial skeletal involvement with older age at onset [(38±11) years] and lower prevalence of severe acne (11.2％);Cluster 2 had no axial involvement with younger age at onset [(33±8) years;U=1 800,P=0.010] and higher prevalence of severe acne (26.8％;x2=4.567,P=0.033).Cluster l patients had been treated more aggressively by baseline compared with Cluster 2 patients;and were more frequently prescribed TNF-α inhibitors (32.8％ vs 2.4％;x2=1 672.5,P＜0.01) and bisphosphonates (39.7％ vs 19.5％;x2=1962,P=0.032).Nonetheless,the disease activity indices were significantly higher at baseline in Cluster 1 than Cluster 2 patients [Bath ankylosing spondylitis disease activity index (BASDAI) (3.5±1.8) vs (2.8±2.0);U=1 800,P=0.010] [Bath ankylosing spondylitis functional Index(BASDFI) (2.4±2.3) vs (1.5±1.7);U=1 791,P=0.009).Moreover,Cluster 1 patients had significantly increased inflammatory markers at baseline compared with Cluster 2 patients [erythrocyte sedi-ment-ation rate(ESR) (34.9±2.9) mm/1 h vs (19.0±14.6) mm/1 h;U=1 204.5,P＜0.01] [high-sensitivity C-reactive protein (hs-CRP) (16±19) mg/L vs (8±11) mg/L;U=1 628,P=0.01].Conclusion Char-acterized by the presence or absence of axial skeletal involvement,two disease subtypes exist in SAPHO syndrome,which exhibit distinct features in age at onset,the prevalence of severe acne,and disease severity.
