Objective To explore the relationship between preoperative serum pro-adrenomedullin (pro-ADM) in the patients with closed rupture of small intestine,and postoperative secondary abdominal infection,and to study the value of postoperative serum pro-ADM in assessment of severity of postoperative secondary abdominal infection of this patients.Methods Eighty-five patients with closed rupture of small intestine treated in the emergency surgery from June 2014 to May 2015 were selected.According to the presence of postoperative abdominal infection or not,these patients were divided into infection group and non-infection group.The infection group was further divided into SIRS,sepsis,severe sepsis,septic shock subgroups as per the severity of infection.The levels of serum pro-ADM,interleukin-6 (IL-6),C-reactive protein (CRP) were determined and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was calculated at admission and the first day、the second day and the third day after operation.Comparisons of these biomarkers were carried out to find out the factors associated with postoperative abdominal infection.In addition,ROC curve was used to verify the factors for predicting the abdominal infection of these patients after operation.The relationship between serum levels of pro-ADM and APACHE Ⅱ score after operation was analyzed.The severity of abdominal infection after operation was assessed with laboratory findings.Results Compared with non-infection group,preoperative and postoperative serum pro-ADM (P =0.03,P ＜ 0.01),IL-6 (P =0.02,P ＜0.01) levels and APACHE Ⅱ scores (P ＜ 0.01,P ＜ 0.01) were significantly higher in infection group (P ＜ 0.05).In the infection groups,the postoperative levels of serum pro-ADM and APACHE Ⅱ scores were increased with the severity of infection increased (r =0.924),and the difference between the groups was statistically significant (P ＜ 0.05),but there were no significant differences in IL-6 and CRP levels between two groups.Conclusion (1) The serum levels of pro-ADM before operation has value in predicting the genesis of abdominal infection in these patients after operation.(2) The serum levels of pro-ADM after operation has value in severity assessment of abdominal infection in these patients after operation.

AIM: To observe the neovascularization process with no intervention in rat allogenic penetrating keratoplasty. METHODS: Allogenic penetrating keratoplasties were successfully performed in 34 female SPF SD rats with no intervention after operations. Corneal neovascularization(CNV) process was noted on day 4, 7, 15 and 30 with operating microscope. The vascular area surface was calculated using the formula C/12×3.14×[r2-(r-I)2].RESULTS: CNV was noted in 29 out of 34 rats (85%). Firstly, the new vessels distributed around the cornea like a brush then gradually extended towards the center. The vessels were distorted and massive with branched tails, they continued growing to reticulated veins in peak time then gradually atrophied. The average neovascularization area (SE) on day 4, 7, 15 and 30 was 11.8±3.5mm2, 18.5±4.0mm2,14.4±4.3mm2 and 6.0±1.8mm2 respectively and 12.7±1.9mm2 in total. The average percentage that new vessels accounting the whole cornea area(SE) was 30.8%±8.7%, 65.3%±12.8%, 59.4%±14.5%,36.2%±10.9% and 48.7%±6.4% in total.CONCLUSION: In rat allogenic penetrating keratoplasties without intervention, CNV presented on day 4 and reached the maximum area on day 7. Then the vessels gradually atrophied, about 50% of the maximum area still remained on day 30.

ObjectiveTo investigate the values of C-reactive protein (CRP) and pleural effusion in predicting the severity in the early stage of severe acute pancreatitis (SAP) . Methods A total of 89patients with acute pancreatitis were collected from October 2008 through October 2010 for retrospective analysis. Patients were divided into two groups, namely mild acute pancreatitis (MAP) group and SAP group as per the Guidelines for Clinical Diagnosis and Classification of Acute Pancreatitis set by the Society of Chinese Medical Association in 2003. The levels of CRP were measured on the 1st, 2nd, 3rd and 7th days after admission. Pleural effusion was also observed on the 1 st day after admission. The data of two groups were analyzed and compared. ResultsThere were significant differences in CRP at all intervals between SAP group and MAP group (P ＜0.05) . The relative risk of increase in CRP ( ＞ 150 mg/L),pleural effusion and increase in CRP along with pleural effusion were analyzed, and each of these three markers can be used as an independent severity factor of SAP. Particularly, increase in CRP along with pleural effusion could be most sensitive in predicting the severity of SAP with relative risk (RR) to be 4. 8 and specificity of predictive value to be 100％. ConclusionsC-reactive protein and pleural effusion are available, simple and economic biomarkers which can help us predict the risk of acute pancreatitis in the early stage.

Objective To study the effect of small interfering RNA targeted on Apollon for proliferation on pancreatic cancer cells and its possible acting mechanism.Methods The small interfering RNA targeted on apollon in our previous study was transfected to the cells using LipofectamineTM 2000,after 48 hours transtection.The inhibitory effects of small interfering RNA targeted on Apollon (Apollon siRNA)on cell proliferation were detected by WST-8.Their inhibition rate and IC50 were calculated.The percentage of apoptosis cells were determined by flow cytometry.The expression of Apollon mRNA was analyzed by real time fluorescent quantitative reverse transcription polymerase chain reaction.The Apollon protein ex-pression levels were detected by western blotting.Results Apollon siRNA could effectively inhibit the proliferation of pan-creatic cancer cell.The amount of apoptotic cells increased significantly.The early apoptotic rate was 37.1%,and the RT-PCR results showed that the relative expression levels of Apollon mRNA were down-regulate,and shows a dose-effective-ness relations.The protein expression levels were decreased by Apollon siRNA.Conclusion Apollon siRNA can effectively inhibit the proliferation of pancreatic cancer cell.The mechanism may be work together to promote pancreative cancer cell early apoptosis and decreased the expression levels of gene and protein,which provides a novel potential approach for treat-ment of target therapy of pancreatic cancer.

AIM: To investigate the inhibition of the recombinant human endostatin adenavirus (Ad-Es) on the experimental choroidal neovascularization(CNV) models by intravitreous injection.METHODS: Experimental CNV models were induced by semiconductor laser in 30 male Brown Norway(BN) rats and randomly divided into 3 groups with 10 rats in each group.At 21d after photocoagulation, the single administration group were given intravitreous injection with Ad-Es 0.01mL;the repeated administration group were given intravitreous injection with Ad-Es 0.01mL and a repeated injection 7d later;the saline control group were given intravitreous injection with saline 0.01mL.At 7d after final administration, the leakage of fundus fluorescein angiography (FFA) was observed.Various CNV areas were measured by using laser confocal microscopy of choroidal flatmount method.Pathology and ultrastructure were observed with light microscopy, the expressions of CD105 were measured by immunohistochemistry.RESULTS: The leakage of CNV of the administration group abviously decreased as compared with those in the saline group, the leakage of repeated administration group decreased compared with that of single administration group (P<0.05).Laser confocal microscope quantitative CNV analysis showed that CNV area of the administration group was significantly smaller than that of control group, the area of repeated administration group was smaller than that of single administration group (P<0.05).Under the light microscope, the vascular endothelial cell number and quantity of the administration group were significantly lower than that of the control group, the cell number of repeated administration group was lower than that of single administration group.CD105 expression of the administration group was significantly weaker than that in the saline group;the expression of repeated administration group was weaker than that of single administration group.CONCLUSION: Ad-Es can effectively inhibit semiconductor laser induced CNV in BN rats, and the inhibition effect of repeated administration group is better than that of single administration group.It may be a useful new method in the treatment of CNV.

Objective To compare the cardiac function parameters in gated SPECT determined by filtered back projection (FBP) and OSEM reconstruction methods. Methods One hundred and forty-four patients underwent 99Tcm-MIBI gated-SPECT imaging studies. The parameters LVEF, EDV and ESV, were derived using quantitative gated SPECT (QGS), four-dimensional model SPECT (4D-MSPECT) and emory cardiac toolbox (ECToolbox) softwares. Each image was reconstructed by FBP or OSEM. Bland-Altman analysis and paired t-test were applied to evaluate those parameters. Results Correlation coefficients for LVEF, EDV and ESV between FBP and OSEM methods were all more than 0.93 (all P<0.001). EDV calculated by FBP was lower than that by OSEM using QGS software, but became the opposite when using 4D-MSPECT and ECToolbox softwares. (QGS: (82.2±39.1) ml vs (83.5±40.8) ml, t=-2.53, P<0.05; 4D-MSPECT: (93.5±46.9) ml vs (88.8±45.2) ml, t=5.95, P<0.01; ECToolbox: (106.4±51.1) ml vs (100.8±49.0) ml, t=3.99, P<0.01). ESV calculated by FBP was higher than that by OSEM using 4D-MSPECT software (4D-MSPECT:(37.5±41.4) ml vs (34.8±37.6) ml, t=3.92, P<0.01). LVEF calculated by FBP was lower than that by OSEM using QGS software ((62.1±16.9)% vs (63.1±16.1)%, t=-3.14, P<0.05), but higher than that by OSEM using ECToolbox software ((74.1±18.8)% vs (71.3±17.1)%, t=5.28, P<0.01). Conclusion Generally, cardiac functional parameters based on FBP and OSEM construction methods correlated well, although they might have singnificantly different results.
