Objective To explore the expression of Twist protein in the colorectal cancer (CRC) and its relationship between clinicopathological factors and prognosis of patients.Methods The clinical data of 45 patients with colorectal cancer who were admitted to the First People's Hospital of Shunde from June 2005 to September 2005 were retrospectively analyzed.The colorectal tissue specimens from surgical resection were collected.The expressions of Twist protein in the cancer and paracarcinoma tissues were examined by the immunohistochemistry,and their relationship with clinicopathological factors and prognosis of patients was analyzed.Patients were followed up by outpatient examination and telephone interview until September 2013.The count data were analyzed using the chi-square test and Fisher exact probability.The survival curve was generated using the Kaplan-Meier method,and the survival analysis was conducted using the Log-rank test.The prognosis factors were analyzed by the COX univariate analysis and multivariate analysis.Results The expression of Twist protein in CRC was predominantly detected in the cytoplasm of the tumor cells.The positive expression rates of Twist protein in the CRC and paracarcinoma tissues were 62.2％ (28/45) and 20.0％ (9/45),respectively,with a significant difference (x2 =18.383,P ＜0.05).The positive expression rates of Twist protein were 42.1％ in patients with Ⅰ-Ⅱ stage of CRC and 76.9％ in patients with Ⅲ-Ⅳ stage of CRC.The positive expression rates of Twist protein were 41.7％in patients with N0 stage of CRC and 85.7％ in patients with N1-N2 stage of CRC.The expression of Twist protein in patients with CRC was however associated with the TNM stage and lymph node metastasis (x2=5.662,9.244,P ＜ 0.05).A total of 45 patients were followed up for 10-96 months (median,54 months).The median survival time and 5-year cumulative survival rate in 45 patients with positive expression of Twist protein were 44 months and 10.7％,which were compared with 69 months and 82.4％ in 45 patients with negative expression of Twist protein,with a statical significance in the survival (x2 =26.147,P ＜ 0.05).The results of univariate analysis showed that the expression of Twist protein was an related factor affecting the prognosis of patients [HR =8.669,95％ confidence interval (CI):2.959-25.390,P ＜0.05].The results of multivariate analysis showed that the positive expression of Twist protein was an independent risk factor affecting the prognosis of patients (HR =5.059,95 ％ CI:2.888-8.863,P ＜ 0.05).Conclusiors The increasing expression of Twist protein in the CRC is positively correlated with the occurrence and development of CRC.The positive expression of Twist protein is an independent risk factor affecting the prognosis of patients with CRC.

OBJECTIVE: To investigate the risk factor,type and characteristic nystagmus of the otolith abnormal migration during diagnosis and treatment for posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV). The therapy and prevention is also discussed. METHOD: Four hundred and seventy-nine patients with PSC-BPPV were treated by Epley's canalith repositioning procedures(CRP) from March 2009 to March 2012. We observed otolith abnormal migration complicating during diagnosis and treatment. According the type of otolith abnormal migration, the additional repositioning maneuver was performed. RESULT: The rate of complication was 8. 1%(39/479), with canal conversion in 5.4%(26/479) and primarily canal reentry in 2.7%(13/479). The rate of incidence of conversion to horizontal canal conversion and anterior canal were 4. 8%(23/479)and 0. 6%(3/479) respectively. All the patient was cured in follow up. The risk factors were unappropriated head movement during or after CRP, including another Dix-Hallpike were performed immediately. CONCLUSION To prevent the complications,the pathognostic positioning sequence and angle of head rotation are commenced during CRP. Appropriate short time postural restrictions post-treatment is necessary. Careful observation of nystagrnus variation is crucial to determine the otolith abnormal migration.

Objective To study the biological changes and the collagen synthesis of the primary cultured skin fibroblast treated with Cigarette Smoke Extract (CSE). Methods The morphological changes of fibroblasts after 24 hours' treatment with CSE were observed with invert microscope. The inhibitory effect at different concentrations of CSE on fibroblast activities was determined by the tetrazolium dye colorimetric test (MTT Test). The growth curves of fibroblasts treated with CSE were drawn with MTT method. Cell aging was observed with β-galactosidase, which was the biological marker of senescence. Flow cytometry (FCM) was used to estimate cell cycle phases after the fibroblasts were treated at different concentrations of CSE and different time. The mRNA expression of type Ⅰ procollagen was detected by RT-PCR. Results After the treatment, the fibroblasts displayed morphological changes and the growth of fibroblasts was apparently slowed down by CSE. The positive β-galactosidase staining was observed in the treated fibroblasts, which were affected by CSE for 5 passages. FCM analysis demonstrated that CSE decreased the cells in S phase and increased the cells in G1 and G2 phase. The result of RT-PCR showed that type Ⅰ procollagen was decreased after the treatment with CSE. Conclusion CSE can not only inhibit the growth and proliferation of the skin fibroblasts, but also decrease collagen synthesis of dermal fibroblast which is very important to the skin health.

Objective To investigate the expression profile variation of long non-coding RNAs (lncRNAs) in ankylosing sporidylitis (AS) and explore the role of lncRNAs in the pathogenesis of AS.Methods The peripheral blood mononuclear cells of AS patients and health controls (HC) were used to detect for differently expressed lncRNAs by microarray.The roles of lncRNAs were predicted with GO and pathway analysis.The results were verified by real time-polymerase chain reaction (PCR).Results A total of 148 lncRNAs and 134 mRNAs were detected,which had more than 2-fold differentially expressed in AS patients.Bioinformatics analysis found that GO term enrichment included protein binding,regulation of transcription,metabolism,signal transduction,et al.and might involve in toll-like receptor pathway,protein kinase,complement pathway,notch signaling pathway and so on.The expressions of three lncRNAs were estimated by real time-PCR which found that consistent with that of microarrays.Among these,D90064 was the most aberrantly expressed lncRNAs.Conclusions Several lncRNAs expression was changed significantly in AS patients in comparison with HC,which implies that those different lncRNAs may have an important role in the development and progression of AS.

Objective To investigate the role of long noncoding RNA-AJ227913 in the pathogenesis of primary gout arthritis (GA). Methods The subjects were divided into three groups:30 acute gout patients (AGA), 30 non-acute gout patients (NAGA), 30 healthy controlsand 30 hyperuricemia patients (HUA). Real-time quantitative polymerase chain reaction (RT-qPCR) was employed to examine the expression of AJ227913 in peripheral blood mononuclear cells(PBMCs) from four groups. 100 μg/ml monosodium urate (MSU) was used to stimulate the peripheral blood of NAGA and healthy controls patients. Then the expression ofAJ227913 was detected by RT-qPCR. Kruskal-Wallis test, Mann-Whitney test, Spearman correlations were used for statistical analysis. Results The expression level of AJ227913 in the AGA group (0.0557 ±0.0156) was higher than that in the NAGA group (0.0223±0.018) and healthy controls group (0.0038±0.0013). There was significant difference between the NAGA group and healthy controls group (P>0.05). Compared with the control group, the expression of AJ227913 in NAGA group which were stimulated by MSU was significantly increased. The Spearman correlation analysis found that the AJ227913 expression levels in GA groups were correlated with UREA (r=0.608, P<0.01), CREA (r=0.337, P<0.05), CYSC (r=0.422, P<0.01). Conclusion Altered expression of AJ227913 may be involved in the inflammatory process of GA and the balance of uricacid.
