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.

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.

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.

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.
