Objective To explore the effect of developed operating instrument set for cesarean section. Methods Toally 216 parturients to undergo cesarean section in our hospital during May to December 2014 , were divided into observation group and control group, 108 cases in each group:in the observation group the developed operating instrument set was used and in the control one, the routine operating instrument set was used. The two groups were compared in terms of contamination rate and the time for postoperative operating room preparation. Results The contamination rate of the observation group was significantly lower than that of the control group (P<0.01). The time for postoperative operating room preparation of the observation group was significantly shorter than that of the control group (P < 0.01). Conclusion The developed operating instrument set can reduce the rate of contamination at the operated area during cesarean section and shortned the time for postoperative operating room preparation , thus enhancing the work efficiency.

Objective ToexploretheapplicationofVasoCT,astentimagingtechnique,instent-assisted coilaneurysmembolization.Methods Twentyconsecutivepatientswith23intracranialaneurysmswere treated with stent-assisted aneurysm embolization in the General Hospital of Armed Police Forces from December 2013 to November 2014 were enrolled. The patients performed VasoCT scan immediately after procedure. Then all the available images were used for stent-optimized reconstruction respectively. Under the XpertCT mode,the available images were observed with both volume imaging and maximum intensity projection. The available images were analyzed and they were divided into very clear,less clear,and not clearaccordingtothestentdevelopingclarity.Results Ofthe22aneurysmstreatedwithstent-assisted embolization,16 were occluded completely,6 were occluded partially. All the stents were expanded completely and were released to the expected locations;11 aneurysm stents developed clearly,9 developed less clearly,and 2didnotdevelopclearly.Conclusion VasoCTcanbeusedinthestent-assistedaneurysmembolization.It can clearly reveal the microscopic structure of the stents,location,relationship with the artery wall,and relationship between stents and coils. The clarity of stent development is associated with the diameters of the packed coils,and the stents are also affected by the metal artifacts projecting direction and the dense degree of the packing coils.

Objective To investigate the expression levels of BDNF, trkB and ChAT mRNA and proteins in the brain of adult tree shrews ( Tupaia belangeri ) .Methods Quantitative real-time PCR was employed to detect the expression levels of BDNF, trkB and ChAT mRNA in the hippocampus, basal ganglia and frontal cortex of adult tree shrews.The expression levels of BDNF, trkB and ChAT proteins andβ-actin was used as internal standard.Results The expression level of BDNF mRNA was highest in the hippocampus of adult tree shrew, and there were significant differences between that in the hippocampus, and basal ganglia and frontal cortex (P<0.01).The expression level of trkB mRNA was higher in the frontal cortex than in the basal ganglia and hippocampus, showing a significant difference between them ( P<0.05).The expression level of BDNF protein was significantly higher in the basal ganglia than in the hippocampus or frontal cortex (P<0.01).There were no significant difference (P>0.05) in the expressions of trkB protein among the hippocampus, basal ganglia and frontal cortex of the adult tree shrews.There were no significant differences in expressions of ChAT mRNA and protein among the hippocampus, basal ganglia and frontal cortex in adult tree shrews ( P>0.05 ) . Conclusions The expression levels of ChAT mRNA were consistent with that of ChAT protein in the hippocampus, basal ganglia and frontal cortex of adult tree shrews, while the expression levels of BDNF and trkB mRNA were not consistent with their proteins, which might indicate that the transcriptional regulation pattern might be more complex.Tree shrew is a valuable animal model in the study of mechanism of BDNF/trkB gene expression.

Objective: To analyze the burden of disease attributable to low fruit intake among Chinese population aged ≥15 years old between 1990 and 2013. Methods: We used data from the 2013 Global Burden of Disease Burden of Disease Study to study the situation in China. The population attributable fraction was calculated to estimate and compare the death and disability-adjusted life years (DALY) attributed to low fruit intake between 1990 and 2013 in China (excluded Taiwan, China). An average world population age structure of the period 2000-2025 was adopted to calculate age-standardized rates. Results: Deaths attributable to low fruit intake accounted for 11.02% of all death in 2013, which were higher than it in 1990 (10.38%). In 2013, the number of deaths attributed to low fruit intake in China increased to 1 046 500 from 793 800 in 1990. From 1990-2013, the age-standardized death rate attributable to low fruit intake decreased from 113.04/100 000 to 79.80/100 000. DALYs caused by low fruit intake increased from 18.346 5 million in 1990 to 21.296 7 million in 2013. Compared with 1990, the age-standardized DALY rate attributed to low fruit intake decreased by 34.67%. In 2013, the top three provinces with the highest burden of disease attributed to low fruits intake were Tibet, Guizhou and Xinjiang provinces, with standardized DALY rate at 2 612.53/100 000, 2 281.85/100 000 and 2 198.22/100 000, respectively. Compared with the results in 1990, the standardized DALY attributed to low fruits intake decreased, especially in Tianjin, where decreased by 63.61%; followed by Aomen, Zhejiang, Shanghai and Beijing, where decreased by 59.74%, 59.53%, 56.64% and 53.88%, respectively. Conclusion Compared with the situation in 1990, the burden of disease attributable to low fruit intake decreased in 2013, but the situation is still serious, especially in Tibet, Guizhou and Xinjiang provinces, where the burden decreased comparatively slowly.

Objective:To study anti-tumor effect of Dunhuang medical prescription Dabupi Decoction on gastric cancer-bearing mice and effect of Dabupi Decoction combined with oxaliplatin on inflammatory immunity of gastric cancer-bearing mice based on IL-17/NF-κB signaling pathway.Methods:Mouse model of MFC gastric cancer subcutaneously bearing tumor was established and ran-domly divided into model group,oxaliplatin group,high,medium and low doses of Dabupi Decoction combined with oxaliplatin groups[21.58,10.79,5.40 g/(kg·d)],with 10 mice in each group,male and female cage rearing.Administration began after 8 days of inoculation and continued for 14 days;next day after the last administration,eyeball blood was taken,mice were killed,tumor tissues were taken and weighed,and tumor inhibition rate was calculated.ELISA was used to detect contents of IL-17 and IL-6 in mice serum,immunohistochemistry(IHC),RT-qPCR and Western blot were used to detect IL-17,IL-6,NF-κB and p-NF-κB mRNA and protein expressions in mice tumor tissues,respectively.Results:Tumor inhibition rates of oxaliplatin group,high,medium and low doses of Dabupi decoction combined with oxaliplatin groups were 33.02%,52.92%,46.33%and 39.52%,respectively,and tumor quality of each treatment group was significantly lower than that of model group(P<0.01).High,medium and low doses of Dabupi Decoction combined with oxaliplatin groups were higher than that of oxaliplatin group.Compared with model group,contents of IL-17 and IL-6 in serum and expressions of IL-17,IL-6,NF-κB p65 and pNF-κB p65 mRNA and protein in tumor tissues in each treatment group were significantly reduced(P<0.01,P<0.05).Compared with oxaliplatin group,levels of IL-17 and IL-6 in serum and expres-sions of IL-17,IL-6,NF-κB p65 and pNF-κB p65 mRNA and protein in tumor tissues in high and medium doses of Dabupi Decoction combined with oxaliplatin groups were significantly reduced(P<0.01,P<0.05).Conclusion:Dunhuang medical prescription Dabupi Decoction has a certain anti-tumor effect on MFC gastric cancer-bearing mice,which can regulate inflammatory immunity and inhibit occurrence and development of gastric cancer by inhibiting IL-17/NF-κB signaling pathway.
