Objective To investigate the expression of Rap1 GTPase-activating protein 1 (Rap1GAP),matrix metalloproteinase 2 (MMP-2) and matrix metalloproteinase 9 (MMP-9),and their relation with clinical patterns in colorectal carcinoma.Methods Immunohistochemistry was used to detect the expression of Rap1GAP,MMP-2 and MMP-9 in colorectal carcinoma,villous adenoma,tubular adenoma and normal colorectal tissue,and their relationship with clinicopathological parameters was analyzed.Results The positive rate of Rap1GAP expression was 30.4 ％ (14/46),77.8 ％ (14/18),69.6 ％ (16/23) and 95.2 ％ (20/21) in colorectal carcinoma,villous adenoma,tubular adenoma,and normal colorectal tissue,respectively (x2 =30.659,P=0.000).The figures were 71.7 ％ (33/46),55.6 ％ (10/18),52.2 ％ (12/16) and 9.5 ％ (2/21) for the positive rate of MMP-2 expression (x2 =22.459,P =0.000),as well as for 76.1％ (35/46),61.1％ (11/18),56.5 ％ (13/23) and 14.3 ％ (3/21) for the positive rate of MMP-9 expression,respectively (x2 =22.643,P =0.000).In patients with colorectal carcinoma,the expression of Rap1GAP was correlated with tumor differentiation (x2 =5.275,P =0.022),but not sex,age,or lymphatic metastasis (all P ＞ 0.05).The expression of MMP-2 and MMP-9 were correlated with lymphatic metastasis (x2 =6.661,P =0.010;x2 =8.475,P =0.040),but not sex,age or tumor differentiation(all P ＞ 0.05).There was a negative correlation between expression of Rap1GAP and MMP-2,MMP-9 in colorectal carcinoma,respectively (r =-0.424,P =0.003;r =-0.294,P =0.048),but no correlation between the expression of MMP-2 and MMP-9 (r =0.101,P =0.505).Conclusions Rap1GAP,MMP-2 and MMP-9 play important roles in the malignant biological behavior of colorectal carcinoma,and the expression of Rap1GAP is negatively correlated with MMP-2 and MMP-9.The interactions among the three affect the occurrence and development of colorectal carcinoma.

Objective To investigate the effect of continuous positive airway pressure (CPAP) on seizure frequency in epilepsy patients complicated with obstructive sleep apnea (OSA). Methods Subjects were divided into CPAP group (20 subjects) and medication group (22 subjects) according to whether they can tolerate CPAP. CPAP group were treated with CPAP combined with antiepileptic drugs. Medication group were treated with antiepileptic drugs alone. Seizure frequency and apnea-hypopnea index (AHI) were compared between groups before and after 4 weeks and 24 weeks of treatment. Results Baseline seizure frequency and apnea-hypopnea index (AHI) were compared between groups(P>0.05). A sig?nificant reduction of seizure frequency was observed in CPAP group after 4 weeks and 24 weeks of treatment compared to that before treatment (P<0.01). In medication group, no significant difference in seizure frequency was noted betweem 4 weeks and 24 weeks after treatment compared to that before treatment(P>0.05). A significant reduction of AHI was ob?served in the CPAP group after 24 weeks of treatment compared to that before treatment (P<0.01), but no change of AHI by treatment was observed in medication group (P>0.05). Conclusion Treatment of OSA in patients complicated with epilep?sy may improve seizure control in short and long term, but longer observation time and more samples are needed for further research.

Objective Using ROC curve to determine the best cut-off point of serum HE-4 in the diagnosis of ovarian cancer and provide important value to diagnosis early ovarian cancer.Methods The levels of serum HE-4 in 68 ovarian cancer pa-tients,42 ovarian benign tumor patients and 30 healthy female were detected by electrochemistry irradiance method.The ROC curve was drawn and the cut-off point of HE-4 was determined by statistical software.Results The levels of serum HE-4 were all non-normal distribution in the groups of ovarian cancer,ovarian benign tumor and healthy controls.Whats more,there was no significant difference between ovarian benign tumor group and normal control group.And compared with benign ovarian tumors and normal control group,the level of HE-4 in ovarian cancers was significantly increased (P <0.01).It would be best for diagnosis when the level of serum HE-4 was 108pmol/L in ovarian cancer.Youden’s index showed the maximum (0.713)and the sensitivity and specificity of diagnosing were 77.9% and 93.1% respectively.The positive predictive value was 91.4% and negative predictive value was 91.4%.At the same time,the positive likelihood ratio was 11.6 and the negative likelihood ratio was 0.2,odds ratio reached to 47.3.Conclusion The detection of HE-4 is an ideal mark for diagnosing and excluding ovarian cancer.Selecting 108 pmol/L as ovarian cancer diagnosis point is relative appro-priate.

Objective To explore the methylation status of Rap1 GTPase activating protein (Rap1GAP) promoter in colon cancer, and to provide the oretical basis and research direction for the early diagnosis, targeted therapy, anti-multidrug resistance of colon cancer and so on. Methods The paraffin embedded specimens of 33 patients with colonic adenocarcinoma diagnosed by pathology were analyzed from Department of Pathology of Xinzhou City People′s Hospital from January 2010 to September 2014, including 19 males and 14 females, and aged 41-72 years old. The paraffin embedded specimens of 16 patients with colonic adenoma were enrolled, including 9 males and 7 females, and aged 34-58 years old. 13 normal tissues from the tumor distal margin (from the tumor > 15 cm) were selected. Quantitative methylation specific PCR (q-MSP) was applied to detect methylation level of Rap1GAP gene promoter. The methylation level differences of Rap1GAP gene promoter region among 3 groups or between different clinicopathologic factor subgroups were compared. Results The methylation rates [median (interquartile range)] of Rap1GAP promoter were 65.43 % (50.35 %), 21.37 % (8.39 %) and 17.43 % (15.71 %) in colonic adenocarcinoma group, colonic adenoma group and adjacent normal tissue group, respectively. The methylation rate of colonic adenocarcinoma group was significantly higher than that of colon adenoma group or that of adjacent normal tissue group (P< 0.05). The methylation rates of Rap1GAP promoter in colonic adenocarcinoma were not correlation with age, sex, differentiation and the stage of TNM [ male vs. female: 42.74 % (70.44 %) vs. 21.98%(80.00%);≤60yearsoldvs.>60yearsold:36.26%(62.62%)and26.23%(76.42 %);well-differentiated vs. moderately/poorly-differentiated: 21.98 % (40.32 %) vs. 42.74 % (74.20 %); TNM Ⅰ-Ⅱ vsⅢ-Ⅳ: 25.31 % (48.27 %) vs. 36.26 % (75.55 %); all P> 0.05]. Conclusion The methylation status of RAP1GAP promoter maybe associate with genesis and development of colon cancer, which might be used as a target for early diagnose of colon cancer.

Objective To explore the CT manifestations of pediatric mesenechymal hamartoma of liver (MHL).Methods Clinical data of 15 cases with MHL confirmed by surgery and pathology were retrospectively analyzed.All children were performed with CT scans including plain and enhanced scans,and the imaging features were analyzed.Results All the lesions were solitary,and 9 masses located at the right lobe of liver,4 located at the left lobe,the others located at both right and left lobe.The maximum diameter of lesions was from 5 cm to 30 cm,with an average of (11.52±6.84) cm.Ten cases were cystic and solid mixed,5 cases were solid.After contrast administration,the solid component and the septa of the masses showed enhancement while no enhancement was observed in the cystic component.Two cases had the spot-like calcification.Conclusion MHL has some special characteristics in the CT scan before surgery,which should be differentiated from other cystic and solid tumors of live.Some MHLs can be diagnosed when combined with the clinical information and CT images.

Objective To detect the expression of humar telomerase reverse transcriptase (hTERT) and telomerase activity in HeLa,MCF-7,SMMC7721 PC-3m and U2OS cell lines. Methods The techniques of immunochemistry and TRAP-ELISA were employed to detect the expression of hTERT and telomerase activity in different tumor cell lines.Results The positive rate of hTERT in HeLa cells(93.75%?3.10%)was significantly higher than that in U2OS cells(2.75%?0.96%),besides the other three cell lines showed an positive rates of hTERT in MCF-7(92.50%?2.65%),SMMC7721 (53.75%?2.22%)and PC-3m(23.50%?2.89%); Meanwhile,the telomerase activity of HeLa cells (94.58%?3.49%) was also much higher than that of U2OS(3.02%?0.43%),likewise the telomerase activities of the other three cell lines (MCF-7,SMMC7721,PC-3m) were 73.90%?4.50%,66.67%?3.35% and 50.62%?1.96%, respectively. Conclusion The expression of hTERT and telomerase activity show obvious differences among five tumor cell lines,suggesting that telomerase inhibitors cannot effect on all the tumor cell lines.

Objective To set up a new method,which is sensitive,low cost,rapid and suitable for clinical application for FTO gene rs9930506 variant genotyping basing on high resolution melting (HRM) platform,and to preliminarily put into practice in susceptibility analysis for metabolic syndrome (MS) in Beijing.Methods Unlabelled probe with C3-spacer block specific for rs9930506 variant has been designed according to the Refseq from GenBank.With LC-Green plus dye pre-mixed,we scanned the signal for the genotype analysis after PCR amplification and HRM reaction.Restriction fragment length polymorphism (RFLP) and PCR-sequencing methods were designed as 2 control genotyping methods for the evaluation of accuracy and convenience.Afterwards,the HRM-based method was put into practice in metabolic syndrome patients (n =500) and control groups (n =500) for rs9930506 genotyping,and primarily study the association between rs9930506 and MS.Results All the 3 methods could genotype rs9930506 appropriately,although the 2 control methods seemed to be a little time-inefficient.The call rate of HRM-method was 100％ and sampling accuracy reached 99.3％ according to sequencing results.In the MS group,AA,AG and GG genotypes were found in 290,185 and 25 cases,respectively.And in the control group,those were found in 344,138 and 18 cases.No genotype distribution difference was detected between control group and HapMap-CHB data (P =0.520 ).The genotype distributions were all in Hardy-Weinberg equilibrium in each group.AA genotype of rs9930506 seemed to reduce the risk for MS( OR =0.626,95％CI =0.483-0.812).Conclusions The AA genotype of rs9930506 variant in FTO might be a protective factor for MS in Beijing population.The susceptibility related genotyping in clinical samples could be more rapid,precise and inexpensive with the development of HRM in genotyping.
