Objective:The expression patterns of TLR4,9,10 in the rat spleen were compared between the rat model of acute skin-transplant rejection and physiologically normal rats ,and their physiological significance were accessed.Methods:6 Wistar and 6 SD rats were used as donors ,and another 24 SD rats were used as recipients which were divided into 4 groups of 6.The same back skin slices were transplanted from donor to recipient , Group A:allograft ( Wistar to SD );Group B:homograft ( SD to SD );Group C:autograft;and Group D:normal SD rats as control.Rat spleens were collected at 1,4,7,10,14,and 21 days after surgery ,and mRNA levels of TLR4,9,10 in splenic mononuclear cells were determined by real-time PCR and corresponding protein expression was accessed by immunohistochemistry.Results:TLR4,9,10 mRNA levels of Group A were significantly higher than that of Group B and C ( P<0.05);TLR4,9,10 mRNA levels showed no significant difference between Group B and C (P>0.05).TLR4,9,10 expressions were moderate (++) to strong (+++) in Group A,and generally weak (+) in Group B,C and D.Conclusion:The patterns of TLR4,9,10 mRNA and protein expression in the rat model of acute skin-transplant rejection indicate that the three genes are involved in acute transplant rejection;the three genes may be expressed coordinately;inhibition of the Toll-like receptors may provide therapeutic targets for acute transplant rejection.

Phage display is a new technology developed in recent years. Random peptides displayed on the filamentous phage surface offer a rich source of molecular diversity in searching for ligands that bind an antibody, receptor and other proteins. The phage display system has been effective in the discovery of various ligands. Potential applications of the peptide library include investigation of the protein protein interactions and discovery of mimetic drug candidates.

Objective To study the change of DNA polymerase beta and XRCC1's expression during malignant celI differentiation.Methods The Eca-109 cells were divided inm 2 groups:differentiation group which cultured with 8-Br-cAMP and control group.The 2 groups cells were cultured 48h simultaneously.The immunocytochemistry was performed to detect the expression of DNA polymerase beta and XRCC1.Results Compared with control group,the expression of DNA polymerase beta and XRCC1 was decreased simultaneously(P<0.05).Conclusion The differentiation agent can down-regulate the expression of DNA polymerase beta and XRCC1,suggesting that overexpressed DNA polymerase beta and XRCC1 maybe result in mutator phenotype.

Objective:The study was attempted to improve the manipulation and eliminate patient's fear for gastroscopy combined with intravenous injection.Methods:A total of 1350 patients wasrandomized into test group (n=1100 given intraveous protofol and midazolam)and the control (n=250,without anesthetics).Patient's feeling,heart rate,blood oxygen saturation,blood pressure,operative duration and operator' satisfaction were recored and analysed.Results:Data in test group showed less complaints,easier manipulation,high satisfaction and no difference in operative duration and blood oxygen saturation as compared with the control.After intravenous administration of protofol and midazolam,patient's heart rate and blood pressure (systolic and diastolic pressure) significantly decreased.Conclusions:With intravenous use of protofol and midazolam,gastroscopy can be achieved effectively,painlessly and safely.

Objective To explore the effectivity and feasibility of uindirectional barbed suture for primary closure of common bile duct on Laparoscopic Exploration of Common Bile Duct Stones, Methods From January 2013 to August 2015,109 cases of primary closure of common bile duct after Laparoscopic Exploration of Common Bile Duct Stones were performed in this hospital.The characteristics of these cases were retrospectively comparatively analyzed.Results Conventional braided Sutures in 68 cases(group A),barbed Suture Devices in 41 cases (group B).There was no difference in postoperative hospital stay,intraoperative blood loss and complication rate between the two groups.Differences in bile duct incision suture time and operative time between the two groups were significantly different.Conclusion The application of uindirectional barbed suture for primary closure of common bile duct using barbed suture after Laparoscopic Exploration is a safe and effective way after treatment of choledocholithiasis.This method cuold reduce the difficulty of operation,and shorten the operation time and the learning curve.

Objective:To explore the effects of medical support program on local diagnosis,treatment and prognosis of acute myocardial infarction(AMI).Methods:Department of Cardiology,Zhongshan Hospital,Fudan University launched medical support program for Fuyuan People′s Hospital in Mar 2010.A total of 103 AMI patients admitted to Fuyuan People′s Hospital during Mar 2010 and Apr 2014 were enrolled.And 5 1 patients admitted during Mar 2010 and Nov 2012 were allocated to group A,while 52 patients admitted during Dec 2012 and Apr 2014 were allocated to group B.The treatment strategy,hospital stay, medication and prognosis were compared between the two groups.Results:Among the 103 AMI patients,male smoking pro-portion was significantly higher than female one(P <0.05).Only 21 patients with ST segment elevation myocardial infarction (STEMI)arrived hospital within 12 h.The thrombolytic therapy rate of patients with STEMI in group B was higher than that in group A(P <0.05).The usage rate of adenosine diphosphate(ADP)receptor antagonist(clopidegrel)during hospitalization in group B was higher than that in group A (P <0.05 ).Only 57 patients were followed up.And only 1/3 of these patients re-ceived consecutive coronary angiography and percutaneous coronary intervention(PCI).After discharge from hospital,the pre-scription rates of ADP receptor antagonist,β-receptor blockers and angiotension converting enzyme inhibitor (ACEI)all de-creased obviously and there was no significant difference between the two groups(P >0.05).There was no significant difference regarding the incidence rates of endpoint events between the two groups(P >0.05).Conclusions:Medical support program im-proves the rates of diagnosis and standardized treatment of AMI during hospitalization.However,the delay before admission has not been shortened yet.Furthermore,there was no standardized secondary prevention and treatment after discharge.Thus,apart from improving the ability of diagnosis and treatment during hospitalization,more attention should be paid to the health education for patients and the training for primary medical staff,and enhance the regional cooperation.

OBJECTIVE:
To investigate the associations between chronic kidney disease (CKD) and body mass index (BMI), waist circumference(WC), waist-to-height ratio (WheiR) in Chinese adults.
METHODS:
A total of 26 655 participants, who voluntarily attended annual health examination at the Health Management Center in the Third Xiangya Hospital of Central South University from June 2013 to February 2014, were enrolled for this study. Logistic regression and receiver operating characteristic (ROC) curve analysis were performed.
RESULTS:
The prevalence rate of CKD was 9.6% and 3.1% in male and female subjects, respectively. Multivariate logistic regression analysis showed that BMI, WC and WheiR were independent risk factors for CKD in diabetic male and hypertensive male subjects (P<0.01). However, no association between these obesity indices and CKD was found in women after multivariate adjustment. In diabetic male subjects, when BMI≥28.7 kg/m(2), WC=90.7 cm and WheiR=0.56, the sensitivity and specificity prediction for CKD was 24.8%, 58.5%, 45.5% and 83.3%, 54.4%, 69.6%, respectively. In hypertensive male subjects, when the optimum cut-off points for BMI, WC and WheiR were ≥
27.0 kg/m(2), 91.2 cm and 0.54, the sensibility prediction for CKD were 41.0%, 47.0% and 50.1%, respectively, while the specificity prediction were 68.0%, 63.0% and 61.4%, respectively. The area under the ROC curve of BMI, WC, WheiR for CKD prediction were 0.56, 0.57, 0.59 in diabetic male subjects and 0.54, 0.56, 0.57 in hypertensive male subjects, respectively.
CONCLUSION
BMI, WC and WheiR are associated with the increased risk for CKD in diabetic or hypertensive male subjects. However, the value for these obesity indices is limited in screening CKD.
