Objective To establish differential protein expression profile specific for serum proteome of cervical carcinoma in Uighur women by protein 2-dimensional liquid phase chromatogra-phy. Methods We collected and prepared sera of cervical carcinoma from Uighur women, and sepa-rated and processed data using 2-dimensional liquid phase chromatography system specific for protein (ProteomeLabTM PF-2D ). Results A differential expression profile of serum proteome based on characteristics of protein isoelectrie point and hydrophobic features was successfully established. Fifty-six differentially expressed protein spots were found, among which there was an obvious difference in 12 peaks. Conclusion Two-dimensional liquid phase chromatography is an effective and feasible method to establish differential expression profile of serum proteome and to offer a new way for the screening of serum protein markers of Uighur women with cervical carcinoma.

Objective To explore the role of Th17 cells in systemic lupus erythematosus (SLE)with cardiovascular disease (CVD).Methods 61 patients of SLE were collected from September 2011 to March 2013 in the Second Hospital of Hebei Medical University by revised SLE classification standards of ACR in 1997.These patients were divided two groups:22patients of SLE with CVD and 39 patients of SLE without CVD;the control group include 20 healthy.Th17 cells were measured by flow cytometry,IL-1 7 was detected by enzyme-linked immunosorbent assay.The correlation among them and the disease active index were analyzed.Results ①The percent of Th1 7 cells in the group of SLE with CVD,that in the group of SLE without CVD and that in control group were (2.09±0.98)%,(1.75±0.75)% and (0.89±0.44)%,respec-tively.The percent of Th1 7 cells in healthy group were lower than that in SLE with CVD and SLE without CVD group (t=4.717~5.030,P<0.001).The level of IL-17 in the group of SLE with CVD,that in the group of SLE without CVD and that in control group were 85.64±20.76 pg/ml,75.25±28.14 pg/ml and 35.06±6.58 pg/ml respectively,and the serum of IL-17 in healthy group were lower than in SLE with CVD and SLE without CVD group (t=6.275~9.954,P<0.001). There were no significant difference of Th1 7 cells and IL-1 7 between SLE with CVD and SLE without CVD groups (t=1.520,P>0.05;t=1.513,P>0.05).②The level of IL-17 were correlated positively with SLEDAI and the anti-double strand DNA (r=0.393,P=0.008;r=0.558,P<0.001),were correlated negatively with complement C3 (r=-0.423,P=0.005).The percent of Th17 cells in CD4+T cells were correlated positively with SLEDAIand the anti-double strand DNA (r=0.681,P<0.001;r=0.492,P=0.015)were correlated negatively with complement C3 (r=-0.534,P=0.027).Con-clusion The level of Th1 7 cells and IL-1 7 were high in SLE,and they were related with the disease activity.The cardiovas-cular factor had not affect the expression of Th1 7 cells and IL-1 7 in SLE.

Objective:To investigate the expression and clinical significance of PD-L1 in colorectal cancer (CRC). Methods:A total of 210 CRC patients who accepted radical surgery in our hospital from January 2015 to January 2016 were divided into three groups, namely, high-frequency microsatellite instability (MSI-H), low-frequency microsatellite instability (MSI-L), and microsatellite stable (MSS). The expression of PD-L1 was detected by immunohistochemistry, and the expression characteristics of PD-L1 in different types of CRC were analyzed. Results:CRC cases with low differentiation had a higher expression of PD-L1 than CRC patients with high differ-entiation (P<0.05). PD-L1 had a positive rate of 75.8%in the MSI-H group and a rate of 9.3%in the MSI-L and MSS groups, wherein the difference between the two groups was statistically significant (P<0.05). Conclusion:PD-L1 was positively expressed in some CRC tu-mor tissues, and its positive rate was significantly higher in MSI-H than in MSI-L and MSS. The therapeutic effect of a PD-L1 blocker for patients with MSI-H CRC might be preferable.

Objective:This study constructs networks and screens potential early-warning plasma biomarkers specific for cervical cancer in Uygur women based on the proteomic data of a previous study by using MetaCoreTM Analysis. This study also explains the canceration mechanism of cervical cancer. Methods:A total of 43 plasma differential core proteins, which were analyzed and identified by proteomic techniques, underwent enrichment analysis of protein functional annotation, biological process, cellular component, GeneGo network distribution and network construction, and biomarker assessment by using MetaCoreTM online bioinformatics software. Results:The result of the MetaCoreTM analysis shows that the negative regulation of cellular component organization, reverse cholesterol transport, and negative regulation of response to stimulus were the most frequently identified functions of the selected differential proteins. The regulation of metabolism, bile acid regulation of lipid metabolism, negative farnesoid X-activated receptor-dependent regulation of bile acid concentration, inflammation complement system, cytoskeleton actin filaments, signal transduction estrogen receptor 1 membrane pathway, and inflammation interleukin-6 signaling were identified as the canonical pathways that are overrepresented in cervical cancer. The MetaCore network of selected proteins, which was constructed using the shortest path algorithm with four plasma proteins (antithrombinⅢ(ATⅢ), clusterin (CLU), villin1 (VIL1), and immunoglobulin kappa locus (IGK@)) as candidate biomarkers, was screened. Conclusion:The proteins ATⅢ, CLU, VIL1, and IGK@can be considered candidate plasma biomarkers of cervical cancer. The mechanism of occurrence and de-velopment of cervical cancer was further explained by MetaCoreTM bioinformatics analysis, thereby enhancing the early-warning system for cervical cancer.
