Objective To determine the expression of serum proteins in pancreatic cancer patients based on mass spectrometry to screen differential proteins and to find potential molecular biomarkers to prediagnosis of pancreatic cancer. Methods The technique of isobaric tags for relative and absolute quantitation (iTRAQ) and two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC-MS/MS) were used to analyze the serum proteins in 15 pancreatic cancer patients and 10 healthy controls. Screening for serum differential proteins was performed via retrieving Panther, Mascot and Scaffold databases. Ingenuity Pathway Analysis was used to detect the correlation between proteins. Results The expression level of 442 proteins was quantified, and 76 proteins were found to be differentially expressed which changed corresponding biological process. The up-regulation of DNA repair protein 50 (RAD50) and down-regulation of transforming growth factor β1 (TGFβ1) and apoptosis protease-activating factor 1 (APAF1) which were correlated with cell growth and apoptosis were found in pancreatic cancer. A closely interacted network was formed between these three differential proteins and other molecules, which could effect metabolism in pancreatic cancer patients. Conclusion Differential expression of serum proteins screened by iTRAQ in pancreatic cancer patients may be the potential markers of pancreatic cancer, which can provide molecular basis for early diagnosis of pancreatic cancer.

Objective: To investigate the combined examination of plasma levels of troponin T (TnT) and N-terminal pro-brain natriuretic peptide (NT-proBNP) for predicting the risk of peri-operative cardiovascular events in elder coronary artery disease (CAD) patients with non-cardiac surgery. Methods: A total of 200 patients from (60-82) years of age with elective non-cardiac surgery were enrolled. The patients were divided into 2 groups: CAD group,n=118 and Non-CAD group,n=82. Plasma levels of TnT and NT-proBNP were examined at 1 day before and 2 days after the operation respectively. The cardiovascular events were recorded in both groups and the best cut-off values for TnT and NT-proBNP in risk prediction were evaluated by receiver operating characteristic (ROC) analysis. Results:①CAD group had the higher levels of post-operative TnT and NT-proBNP than pre-operative; both TnT and NT-proBNP levels were higher in CAD group than those in Non-CAD group at the same time points, allP<0.05.②The total cardiovascular events in CAD group was higher than those in non-CAD group (χ2=5.85,P=0.016) and the individual event was similar between 2 groups.③In CAD group, the best cut-off value for pre-operative TnT in predicting peri-operative cardiovascular events was 18.5 ng/L with the sensitivity at 72% and speciifcity at 69.6%; for NT-proBNP was 98.0 pg/ml with the sensitivity at 90.8% and speciifcity at 74.6%.④The patients with the higher level of pre-operative TnT had the increased risk of total cardiovascular events than those with normal TnT (χ2=4.56,P=0.043), and the same as NT-proBNP (χ2=4.08, P=0.036). Likewise, the patients with higher levels of both pre-operative TnT and NT-proBNP had the increased risk of total cardiovascular events than those with normal TnT and NT-proBNP (χ2=13.32,P=0.000). Conclusion:Either plasma levels of TnT or NT-proBNP could be used as the biomarker for predicting the risk of peri-operative cardiovascular events in elder CAD patients with non-cardiac surgery, the combined examination would have the better predictive value.

Uarthritis is a common inflammatory arthritis, which has been well known as the White Tiger arthritis in traditional Chinese medicine. This article discussed the pathogenesis of blood stasis and the related studies in hyperuricemia, acute and chronic phase of Uarthritis. It suggested that blood stasis is a crucial pathogeny of uarthritis. Thus, the chinese herb medicine of blood circulation drugs should beapplied in all the phases of Uarthritis.

To analyze the change of physiological indices in male and female pilot students during lower body negative pressure (LBNP) exposure, one female group and one male group participated in the experiment. They were subjected to LBNP up to 50 mmHg for 8 min. Electrocardiogram (ECG), heart rate (HR), blood pressure (BP), cerebral blood flow (CBF) and time of exposure were monitored during LBNP. The results showed that during LBNP, heart rate (HR) increased while systolic blood pressure (SBP) and cerebral blood flow (CBF) decreased with the prolongation of exposure. It is concluded that LBNP exposure could produce similar physiological changes in both male and femal pilot students.

Objective To detect the presence of the apoptotic sensory neurons in rat dorsal root ganglion (DRG) following non-freezing cold injury of the sciatic nerve.Methods Thirty three male Wistar rats were randomly divided into three groups (7 d group, 14 d group, 21 d group; n=11 each).The sciatic nerves were cooled to 4 ℃ for 2 hours and the control side underwent sham operation.The pathological examination was performed on L4-6 DRGs at 7, 14, and 21 d post operation.The apoptotic sensory neurons of L4-6 DRGs were detected using FCM (Annexin /PI) and TUNEL staining.Results The apoptotic sensory neurons of L4-6 DRGs were revealed after non-freezing cold injury of the rat sciatic nerve.FCM (Annexin /PI) and TUNEL quantitative analysis indicated that the apoptotic neurons significantly increased in rat dorsal root ganglion (DRG) at 7 d, 14 d, and 21 d post operation following non-freezing cold injury of the sciatic nerve.TUNEL qualitative analysis further confirmed pathological characters of neuron apoptosis in L4-6 DRGs.The apoptotic neurons began to increase from 7~(th) day, reached peak at 14~(th) day, and then decreased slightly at 21 d following operation.Conclusions Non-freezing cold injury on sciatic nerves can cause the sensory neurons apoptosis of L4-6 DRGs.

Objective To investigate the surgical strategy of recurrent rectuvaginal fistula. Methods Retrospectivly analyzed the clinical data of 13 patients with recurrent rectovaginal fistula from December 2001 to December 2008. The etiopathogenisis and the ways of treatment were analyzed. Results All the 13 patients with a transverse colostomy surgical repaired with Mason operation in the secondary intention,and recepted closure of colostomy in the third intention for treatment, all patients were cured. No recurrent fistula was identified with postoperative follow-up 4 - 84 months. Conclusions After recurrent rectovaginal fistula with multiple surgical treatment,the blood supply of local tissue is poor,the scar is serious. Selecting the appropriate timing of operation, adequate preoperative preparation, the application of transverse colostomy and Mason operation in different period could significantly enhance the successful operation rate.

Interferon-tau (IFN-tau) is a newly discovered IFN of type I. It was originally found for its role as a pregnancy recognition hormone in ruminant animals such as sheep and cows. Like the other type I IFNs, IFN-tau have the same biological activities including antiviral, antiproliferative and immunomodulatory effects. In order to clearly identify the function of IFN-tau, the coding sequence of IFN-tau was amplified by PCR from IFN-tau cDNA, this fragment digested by EcoR I and BamH I and was inserted into pBV220 to form the recombinant plasmid pBV220/IFN-tau which was then transformed into E.coli BL21. It was found that pBV220/IFN-tau was highly expressed as inclusion body in BL21. Next, the expressed protein was purified on S-100 High Resolution and the purified product was confirmed by amino acid sequence analysis. Moreover, the standard antiviral activity test indicated that the activity of IFN-tau was about 2.09?106IU/ml.
