Objective To investigate the effects of bevacizunab on the antioxidative function of human retinal pigment epithelium (RPE),in order to explore the possible mechanism of macular atrophy induced by the application of anti-vascular epithelial growth factor (VEGF) agents in age-related macular degeneration.Methods Human RPE cells were incubated in DMEM/F12 medium containing 0.25 g · L-1 bevacizumab and divided into 5 groups according to incubation period:0 hour(control),12 hours,24 hours,48 hours and 72 hours,and then the oxidative stress was induced by adding H2O2.Cell viability was measured by the CCK8 assay.MitoSox Red was used to determine mitochondrial reactive oxygen species (mtROS) production.Mitochondrial membrane potential was measured using the JC-1 assay.The expression levels of NOX4 and HO-1 were detected by RT-PCR and Western blot,respectively.Results CCK8 assay determination showed that the above treatment had no significant effect on cell viability,the cell viability of 0 hours,12 hours,24 hours,48 hours and 72 hours were (100.2 ±3.3)％,(99.2 ±2.7)％,(102.5 ±6.4)％,(103.9 ±3.7)％,(103.6 ±3.3)％,the difference was not statistically significant (P ＞ 0.05).Compared with the control group,the levels of mtROS increased at 12 hours,24 hours,48 hours and 72 hours,the difference was statistically significant (P ＜ 0.05).Mitochondrial membrane potential at 12 hours,24 hours,48 hours,72 hours were lower than the control group,the difference was significant,48 hours reached the lowest,72 hours significantly increased,but still lower than the control group.RT-PCR and western blot results demonstrated that the expression of NOX4 mRNA and protein increased at 12 hours,24 hours,48 hours and 72 hours,and reached the highest at 24 hours,then decreased significantly,but still higher than the control group,the difference was statistically significant (P ＜0.01).Compared with the control group,the expression of HO-1 mRNA decreased at 24 hours,48 hours and 72 hours,while the expression of HO-1 protein decreased at 48 hours and 72 hours,the difference was statistically significant (P ＜ 0.05).Conclusion The clinical concentration of bevacizumab can reduce the anti-oxidative function of RPE cells,which may be one of the causes of progressive macular atrophy after long-term anti-VEGF therapy.

Objective To analyze the institutional cooperation networks of 137 military hospitals in terms of published papers, trends of cooperation and co-authorship in order to guide the cooperation between military hospitals.Methods The institutional cooperation, co-authorship, author-keyword co-occurrence and author-subject co-occurrence in the 137 military hospitals were analyzed with the Thomson data analyzer( TDA) software.Results and Conclusion The institutional coop-eration between military hospitals could be divided into 5 types and were based on the principle of proximity of locations and similiarity of research.The cooperaiton circle with Chinese PLA General Hospital as the center was expanded over time. The institutional cooperation between military and civilian hospitals was also based on the principle of proximity of locations and similiarity of research.Cooperation between productive authors mainly occurred in the same research group but co-au-thorship outside the research group was scarce.The potential competition or cooperation between research fields and authors can be analyzed by comparing co-authorship and author-keyword co-occurrence.

Background and purpose:Cancer is a major public health issue in China and worldwide, which se-riously threatens human beings as well as social and economic development. This study explored the relationships between the cancer distribution characteristics and cancer prevalences in Chinese cancer surveillance regions to provide scientific evidence for cancer prevention and management.Methods:The data were obtained from the book named“Prevalence and Mortality of Cancer in China from 2003-2007” including incidence of 23 cancer types in 32 regions of China published by the Academy of Military Medical Sciences of the Chinese PLA in 2012. Correspondence analysis was used to gain the relation between the prevalence and area distribution. Cluster analysis was used to obtain the classifications with special significance by putting the cancers or regions with similar characteristics into a cluster.Results:Esophageal cancer, gastric cancer, liver cancer, lung cancer, colorectal and anal cancer have high incidence and mortality in both genders. The districts with high incidence of esophageal cancer and gastric cancer were grouped together. The counties or cities (Shexian, Yangcheng, Linzhou, Yanting, Yangzhong and Jianhu) with high incidence of esophageal cancer and gastric cancer were classified into same cluster frequently. Fusui was grouped along because of the lower incidence of various cancers than the national average except for liver cancer. Guangzhou, Sihui and Zhongshan were the districts with high incidence of nasopharyngeal carcinoma in both genders. Rural areas in Qidong and Haimen were classified into a cluster in male and total data for the high incidence of liver cancer. Colorectal cancer, anal cancer and breast cancer in women also had high incidence in urban areas. Cervical cancer had the second level high incidence in women following diseases of digestive system, breast cancer and lung cancer.Conclusion:Similar pathogenic factors may exist in counties or cities of Shexian, Cixian, Yangcheng,etc, because of the high prevalence of esophageal cancer. Similar pathogenic factors may also exist in other districts or cancers that were classified into the same cluster.

The effects of fucoidan on the lipidomics profiling of juvenile yellow catfish (pelteobagrus fulvidraco) during different feeding time (week 1, week 2, week 3 and week 8) were investigated by ultra-performance liquid chromatography-quadrupole-time-of-flight-mass spectrometry (UPLC-Q-TOF-MS) combined with multivariate data analysis, e.g.principal component analysis (PCA) and partial least squares-discriminate analysis (PLS-DA).Based on VIP and p values, 11 lipid biomarkers were screened including lysophosphatidylcholine (Lyso-PC) 16∶0, phosphatidylcholine (PC) 22∶6/16∶0, phosphatidylethanolamine (PE) 22∶6/16∶0, phosphatidylinositol (PI) 18∶0/22∶6, diacylglycerol (DAG) 16∶0/16∶0,DAG 16∶0/18∶1, DAG 18∶1/18∶1, triglycerides (TAG) 20∶5/16∶0/18∶3, TAG 20∶4/16∶1/18∶2, TAG 16∶0/18∶2/20∶5 and TAG 18∶2/14∶0/18∶1.It was found that Lyso-PC, PC, PE and PI had the largest levels at the eighth week;the levels of DAG were decreased at the second and fourth weeks, and increased at the eighth week.While TAG was different: the content of TAG 18∶2/14∶0/18∶1, TAG 20∶5/16∶0/18∶3 and TAG 20∶4/16∶1/18∶2 increased in response to fucoidan, but TAG 16∶0/18∶2/20∶5 decreased little.Therefore, for juvenile yellow catfish, fucoidan can affect its lipid metabolism, which provides a theoretical basis for investigation of the influence of fucoidan on the response mechanism of lipid metabolism of juvenile yellow catfish.

[ ABSTRACT] AIM: To investigate the protective effect of autophagy on oxidized low density lipoprotein ( ox-LDL)-induced macrophage apoptosis and the underlying molecular mechanisms .METHODS:The RAW264.7 macropha-ges were pretreated with 3 mmol/L 3-methyladenine (3-MA), 1 μmol/L rapamycin (Rap) or 4 mmol/L 4-phenylbutyric acid ( PBA) respectively for 1 h and then treated with ox-LDL (100 mg/L) for 12 h.The cell viability and apoptosis were determined by MTT assay and flow cytometry with Annexin V-FITC/PI staining, respectively.The activities of lactate de-hydrogenase ( LDH) in the medium and caspase-3 in the cells were determined by detection kits .The protein levels of bec-lin-1 (a molecular marker of autophagy ), glucose-regulated protein 78 (GRP78, an endoplasmic reticulum stress marker) and C/EBP homologous protein ( CHOP, a key-signaling component of endoplasmic reticulum stress-induced apoptosis ) were examined by Western blot .Microtubule-associated protein 1 light chain 3 (LC3, another molecular marker of autoph-agy) was observed under laser scanning confocal microscope .RESULTS: Treatment of the RAW264.7 macrophages with ox-LDL at 100 mg/L for 12 h resulted in significant decrease in cell viability , and dramatic elevation in LDH leakage , cell apoptosis and caspase-3 activity, which were promoted by 3-MA (an autophagy inhibitor) and inhibited by Rap (an autoph-agy inducer ) .ox-LDL induced autophagy in the macrophages as assessed by beclin-1 upregulation and frequent granulation of LC3, which were inhibited by 3-MA and promoted by Rap.Interestingly, 3-MA enhanced, while Rap blocked, the CHOP upregulation induced by ox-LDL.Moreover , PBA ( endoplasmic reticulum stress inhibitor ) significantly inhibited ox-LDL-induced GRP78 upregulation and autophagy as determined by the attenuation of beclin-1 upregulation and frequent granula-tion of LC3.CONCLUSION: Endoplasmic reticulum stress mediates ox-LDL-induced autophagy in macrophages , and moderates activation of autophagy may protect macrophages from ox-LDL-induced apoptosis by inhibiting CHOP expression .

Objective To explore the association between the CpG methylation level of positive regulatory domain containing 16(PRDM16)gene promoter and obesity or body mass index(BMI). Methods A total of 116 patients(91 female adults and 25 male adults) with abdominal operation in a municipal hospital of Henan province were enrolled in this study and they were divided into two groups:normal weight group(n=50), overweight or obesity group ( n=66 ) . Fasting plasma glucose, total cholesterol, triglyceride, high density lipoprotein and low density lipoprotein were measured in peripheral blood. DNA was extracted from white blood cells in peripheral blood and modified by bisulphite. Then the CpG methylation level of PRDM16 gene promoter was detected by mass spectrometry. Finally, all data were analyzed by IBM SPSS Statistics 21. 0 at the 5% level. The essential features and biochemical indexes of research objects between two groups were compared by two independent sample t-test, except chi-square test for gender. The correlation between CpG methylation level of PRDM16 gene and BMI was analyzed by multiple linear regression. Results There were no significant differences ( P>0. 05 ) in the methylation levels of PRDM16 gene's effective CpG sites(including CpG5. 6, CpG8, CpG9, CpG12, CpG13. 14. 15, CpG26. 27, CpG28 and CpG29) between two groups. The methylation level of CpG26. 27 had positive linear relation with BMI in overweight or obesity group with the standardized coefficients of 46. 928(P=0. 015), which means the higher the methylation level is, the higher the BMI would be. Conclusion The CpG26. 27 methylation level of PRDM16 gene promoter region may have relationship with the risk of obesity.

Objective:To select the animal model more consistent with the pathophysiology of abdominal compartment syndrome (ACS) through the comparative study of the methods of multiple water sacs superimposed compression and gas perfusion.Methods:Ten experimental pigs were randomly divided into two groups ( n = 5): the "constant volume model" (constant volume model group) and the "constant pressure model" (constant pressure model group) of intra-abdominal hypertension. The models were prepared by the method of water sac superposition and pressurization, and artificial pneumoperitoneum respectively. The abdominal pressures of both groups were 25 mmHg (1 mmHg = 0.133 kPa) and observed for 4 hours. The pressure was measured once an hour for 4 hours and the pressure-time curves of the two groups were drawn respectively. The experimental animals were sacrificed 4 hours after modeling. The heart and lung were harvested, and the histopathological changes were observed by hematoxylin-eosin (HE) staining. Results:Two groups of experimental pigs were successfully modeled. The abdominal pressure gradually increased at 0, 1, 2, 3, 4 hours after operation in the constant volume model group (mmHg: 25.0±0, 27.1±0.2, 29.4±0.1, 30.9±0.2, 33.1±0.1), and there was a positive correlation between the abdominal pressure and time (functional equation: Y1 = 25.102 0+1.996 0 X1; R2 = 0.996 2, P = 0.000 1). The abdominal pressure value in the constant pressure model group at 0, 1, 2, 3, 4 hours were maintained 25 mmHg, and there was no linear correlation between the abdominal pressure and time (functional equation: Y2 = 25). HE staining showed that in the constant volume model group, the myocardial fibers were accompanied with hyaline degeneration, significantly reduced transverse lines, part of myocardial fiber atrophy, and visible nuclear aggregation; hemorrhage, chronic inflammatory cell infiltration and inflammatory exudation were found in the lung tissues. In the constant pressure model group, partial atrophy of myocardial fiber, partial hypertrophy, focal hyaline degeneration, disappearance of local striae, hyaline degeneration of myocardial fiber, dilation and congestion of intermyocardial artery were observed. Slight hyperplasia of alveolar epithelium in some areas, heart failure cells, dilation and congestion of bronchi and trachea artery, a large number of red blood cells and uniform light staining substances in lumen were found. Conclusion:After the model was made by the method of multiple water sacs, the pressure of the abdominal cavity continued to increase with the development of the disease, which was in line with the clinical pathological changes of ACS, and was more suitable for making the animal model of the intra-abdominal hypertension.
