Irritable bowel syndrome(IBS)is a commonly seen functional gastrointestinal disorder. Its main clinical manifestations were abdominal pain,abdominal distention and altered bowel habits. Currently,the pathogenesis of IBS has not been clarified. Studies showed that IBS was caused by many factors,including life style,gene polymorphism,food hypersensitivity,psychological factors,brain-gut axis abnormality and intestinal flora disorder. This article reviewed the advances in study on pathogenesis of IBS.

Objective To observe the translations of chemokine CXCL12 and its receptor CXCR4 in endometrial carcinoma tissues,and to evaluate their significance in clinical pathologic features of endometrial carcinoma.Methods From Jan.2012 to Dec.2014,52 tissue specimens of patients with endometrial carcinoma were admitted to the hospital,aged 55.6 ± 19.2 years,and 26 cases of normal endometrium as control,aged 52.3±16.5 years old.Expressions of CXCL12 and CXCR4 in the tissue specimens were detected by immunohistochemistry,and to analyze the relationship between the expressions and clini-cal pathological features,and FIGO stage,cell differentiation,lymph node metastasis and pathological type in endometrial carcinoma.Results In endometrial carcinoma,the positivity rates of CXCR4 and CXCL12 were 76.92% and 69.23% re-spectively.The positive expression rates of which were 34.62% and 30.77% in normal endometrium tissues,statistically significant (χ2 =11.826,P <0.01).The expression of CXCR4 was positively correlated with the differentiation of endome-trial carcinoma cells (P <0.05).In endometrial carcinoma,with the exception of CXCR4 expression and cell differentiation was positively related (r=0.386,P <0.05),CXCL12 and CXCR4 expression and clinical stage,pathological type and lymph node metastasis no correlation was found (P >0.05).Conclusion The results showed that the expression of CXCL12 and CXCR4 in endometrial carcinoma tissues was significantly increased,which may play an important role in the development of endometrial cancer.

Objective To investigate the correlation between methylation status and death-associated protein kinase 1 (DAPK1) in SiHa and Hela cell line of cervical carcinoma and intervention of DNA methyltransferase inhibitor 5-azacytidine on the expression of DAPK1 and the proliferation of the cells. Methods DAPK1 methylation status was analyzed using methylation-specific PCR methods. The expression of mRNA and protein of DAPK1 were analyzed by RT-PCR and SABC methods after the treatment with 5-azacytidine. MTT assay was used to observe the changes of proliferation activity of the cells after 5-azacytidine treatment. Results DAPK1 genes were methylated and did not express in SiHa cells in the cervical carcinoma. Its expression could be restored by 5-azacytidine. MTT assay showed 5-azacytidine could weaken the proliferation of cancerous cells. Conclusion DAPK1 methylation plays an important role in the carcinogenesis of cervical cells and can reexpress after the treatment with 5-azacytidine which also restored its inhibitory function on carcinoma.

Objective To investigate the expression of CXC chemokine receptor 4 (CXCR4) in clear cell renal cell carcinoma (ccRCC) and its relationship with the clinical pathological parameters of ccRCC.Methods The expression of CXCR4 was detected by immuno-histochemistry method in 63 cases of ccRCCs,20 cases of para-carcinoma tissues and 20 cases of normal renal tissues.The correlation between expression level of CXCR4 and clinical pathological parameters of ccRCC patients were analyzed,and the clinical significance of its expression in ccRCC was evaluated.Results The positive expression rate of CXCR4(49.2％) in ccRCCs was significantly higher than that in para-carcinoma tissues (15％) and normal renal tissue (10％),and the difference was statistically significant (P ＜ 0.05).The expression level of CXCR4 and the clinical stage and pathological grade of ccRCC were correlated (P ＜ 0.05),and was associated with lymph node transfer (P ＜ 0.05).The CXCR4 negative group overall survival rate [55.2％ (16/29)] and the average survival time(46 months) was significantly better than the positive group [38.5％ (10/26),32 months;P ＜ 0.05].Conclusions The expression level of CXCR4 in ccRCC is correlated with the clinicopathological parameters and prognosis.CXCR4 is expected to be an important marker for diagnosis and prognosis evaluation of renal cell carcinoma.

ObjectiveTo discuss the effect of argon laser on retinal vein obstruction (RVO) . Methods428 eyes of 422 patients with RVO were treated by argon laser.Among them, there were 386 eyes with ischemic RVO,42 eyes with no-ischemic RVO, and 129 eyes with macular vesicular edema(MVE).ResultsThe vision acuity of 207 eyes is improved, and not changed in 138 eyes. The disappearing rate of MVE is 84.45%(82/97). ConclusionUsing argon laser to treat RVO can curb new vascular of retina building, lighten MVE and protect vision function.

: The recovery of spinal cord injury(SCI) is a difficult problem in neuroscience research field, one of the reasons is that the ability of injured spinal cord regeneration is limited. Recent years many experiments prove that neurotrophin-3 is very important in SCI regeneration recovery, the gene transplantation is effective. This article makes a summary of SCI treatment research advancement.

ObjectiveTo investigate the expression and clinical significance of heat shock transcription factor 1 (HSF1) protein in human hepatocellular carcinoma (HCC) tissues,and deduce the probable molecular mechanism of HSF1 in the development and advancement of HCC.MethodsSixty-seven samples of HCC tissue and 21 samples of normal liver tissue were obtained from March 2006 to March 2007 at the Xijing Hospital.The expressions of HSF1 protein and heat shock protein 70 (HSP70) were detected by using immunohistochemistry.The probable molecular mechanism of HSF1 in the development and advancement of HCC was deduced according to the relationship between the expressions of HSF1 protein and HSP70.Positive rates of HSF1 protein in different tissues and the relationship between HSF1 protein expression in the HCC tissues and clinical pathological factors were analyzed by the chi-square test and by calculating Fisher exact probability,respectively.The correlation between the expressions of HSF1 protein and HSP70 in the HCC tissue was analyzed by the Spearman correlation coefficient.The survival curve was drawn by the Kaplan-Meier method,and the survival rate was analyzed by the Log-rank test.ResultsThe positive rates of HSF1 protein expression was 69％ (46/67) in the HCC tissue,which was significantly higher than 29％ (6/21) in the normal liver tissue ( x2 =10.628,P ＜ 0.05 ),The positive rates of HSP70 expression in the HCC tissue was 57％ (38/67),which was significantly higher than 24％ (5/21) in the normal liver tissue ( x2 =6.929,P ＜ 0.05 ).The expression of HSF1 protein in the HCC tissue was positively correlated with that of HSP70 (r=0.319,P ＜0.05).The high expression of HSF1 protein was correlated with the integrity of capsule of HCC,tumor differentiation and TNM stage (x2 =5.935,9.762,5.159,11.267,P＜0.05 ),while the high expression of HSF1 protein was not correlated with the gender,age,levels of hepatitis B surface antigen and alpha fetoprotein,and portal vein tumor thrombus ( x2 =0.822,0.172,2.059,P ＞0.05 ).The survival time was (21.4 ± 1.9 )months for patients with positive HSF1 protein expression and (29.8 ± 2.7 ) months for patients with negative HSF1 protein expression.There was a significant difference in the survival time between patients with positive and negative HSF1 protein expression ( x2 =4.276,P ＜ 0.05 ).Conclusions HSF1 is correlated with the development,advancement,invasion,metastasis and malignant prognosis of HCC.HSF1 takes effects by regulating the expression of HSP70,and it has a good perspective of clinical application for the diagnosis and treatment of HCC.
