Objective To analyze the association of staphylococcal nuclease domain-containing protein 1(SND1) and T-cell intracellular antigen 1(TIA-1) on stress granules, and the regulation of SND1 on stress granules under stress stimuli. Methods The immunofluorescence assay and laser scanning confocal microscopy were used to observe the co-localization of SND1 protein and TIA-1 protein under stress stimuli, and the over-expression plasmids of pEGFP vector were transfected into HeLa cells and to verify which domain of SND1 co-localized with TIA-1 under stress stimuli. RNA interference-mediated knockdown of the expression of SND1 protein in HeLa cells was measured by Western Blotting assay. Then whether the knockdown of SND1 affected the recruitment of TIA-1 on stress granules was observed. Heat shocks under different times were used to identify whether there were dynamic changes in transportation of SND1 and TIA-1 on stress granules. Results SND1 co-localized with TIA-1 on stress granules under stress stimuli, and the associated domain of SND1 were SN domain. TIA-1 still can be recruited on stress granules but a large amount of stress granules were reduced even though the expression of SND1 protein was decreased. And the transportation of SND1 on stress granules was laged behind TIA-1 under different-times of heat shocks. Conclusion SND1 protein co-localizes with TIA-1 on stress granules, and which co-regulates the cellular stress response under stress stimuli.

Background and purpose:Aberrant DNA methylation that leads to the inactivation of tumor suppressor genes plays important roles in development and progression of breast cancer. Clinically, related gene methylation is considered to be a promising biomarker for tumor diagnosis and prognosis. This study aimed to investigate the methylation status ofSox17 gene in breast cancer tissue and its corresponding plasma circulating DNA, as well as to investigate its value in breast cancer early diagnosis and prognosis.Methods:TheSox17 gene promoter methylation status was detected by MSP in 86 cases of breast cancer, 36 normal breast tissues and its paired plasma DNA, the results were analyzed with corresponding clinical and pathological features.Results:The frequency ofSox17 gene methylation rate among 86 breast cancer tissues was 77.9%(67/86), and was 61.6%(53/86)in plasma circulating DNA, however, noSox17 gene methylation was found in normal breast tissues.Sox17 gene promoter methylation in plasma circulating DNA was signiifcantly associated with the methylation status in tumor tissues (r=0.502,P=0.000). In breast cancer tissue specimens,Sox17 methylation status was significantly correlated with tumor stage (χ2=6.18,P=0.041) and lymph node metastasis (χ2=13.54,P=0.001);Sox17 gene methylation rate was signiifcantly correlated with tumor stage (χ2=27.06,P=0.000), tumor size (χ2=9.65,P=0.007) and lymph node metastasis (χ2=20.80,P=0.000) in plasma samples, and there was no signiifcant difference ofSox17 gene methylation between patient age, histological grade and ER, PR, HER-2/neu status.Conclusion:Sox17 gene promoter methylation plays an important role in the carcinogenesis and development of breast cancer, and may be associated with the prognosis of breast cancer. Furthermore, methylatedSox17 gene may be a useful tumor biomarker in plasma circulating DNA for breast cancer detection and disease monitoring.

Objective To explore the related risk factors of cerebral hemorrhage complicated with stress ulcer (SU). Methods The clinical data of 1 185 patients with cerebral hemorrhage admitted to Department of Emergency Medicine of Nanjing General Hospital from March 2006 to March 2014 were retrospectively analyzed. Patients were divided into two groups according to whether patients complicated with SU or not. Data was collected within 8 hours after admission in two groups including gender,age,amount of bleeding,the bleeding site (basal ganglia,thalamus, brainstem,brain lobe,ventricle,subarachnoid,and cerebellum),disturbance of consciousness,acute physiology and chronic health evaluationⅡ(APACHEⅡ)score,systolic blood pressure(SBP),history of hypertension,and history of cerebral hemorrhage. The statistically significant risk factors found using univariate analysis was selected and was analyzed to find independent risk factors with multivariate logistic regression analysis. The receiver operating characteristic curve (ROC curve)was plotted to analyze the independent risk factors and evaluate their power of test. Results 1 185 patients with cerebral hemorrhage were enrolled in the study,293 cases occurred SU,accounting for 24.7%,and 892 cases without SU,which accounted for 75.3%. As shown by univariate analysis,risk factors for cerebral hemorrhage complicated with SU included age,amount of bleeding,the bleeding site,disturbance of consciousness,APACHEⅡscore,SBP. As to the site of bleeding,brain,thalamus,brainstem hemorrhage complicated with SU were higher proportion,45.3%(43/95),39.1%(63/161),36.9%(48/130),which were significantly higher than those of the lobes of the brain 〔26.2% (33/126)〕,cerebellum 〔18.8% (15/80)〕,basal ganglia〔16.1%(78/485)〕,arachnoid the inferior vena cava 〔12.0% (13/108)〕. Multivariate logistic regression analysis showed that amount of bleeding 〔odds ratio (OR)=3.305,P=0.001,95%confidence interval (95%CI)2.213-48.634〕,the bleeding site (OR=1.762,P=0.008,95%CI 0.123-2.743),SBP (OR=1.223,P=0.034,95%CI 0.245-2.812) were independent risk factors of cerebral hemorrhage complicated with SU. The area under the ROC curve (AUC)of amount of bleeding and SBP were 0.846 and 0.597,suggesting that amount of bleeding has moderate diagnostic value and SBP has low diagnostic value. Conclusions Cerebral hemorrhage patients with large amount of bleeding,the bleeding site in the ventricle,thalamus or brainstem,high SBP are of great risk. We should lower blood pressure and give preventive treatment for SU as soon as possible.

Objective To investigate the clinical features and the effect of gender differences on phenotype of Giteiman syndrome (GS) patients. Methods Clinical features and biochemical parameters were compared and analyzed to look for correlation between male and female GS patients. Results More male patients suffered from nocturia than female patients (P < 0.05), and there were no statistical differences in other clinical features between males and females. The level of serum creatinine was higher in male patients than that in female ones [(82.7±43.3) μmol/L vs (58.7±12.7) μmol/L], but estimated glomerular filtration rate was male patients and female patients. The urinary potassium and chloride excretion fraction were higher in male group than those in female group (33.0%±22.9% vs 17.0%±4.7%;2.30%±1.59% vs 1.23%±0.39%, P< 0.05, respectively). Statistical differences were not observed in other laberatory parameters. Three patients with impaired renal function were all male. Conclusions More male patients suffer from nocturia than female patients. Male patients seem to be prone to impaired renal function. It is speculated that different density of sodium-chloride cotransporter in renal tubule may account for gender differences.

Objective To investigate the plasma levels of tissue factor pathway inhibitor(TFPI)in children with Henoch-Schonlein purpura(HSP)and the changes of it after therapy with heparin.Methods Forty-six HSP children were enrolled in HSP group according to the criterion,and 23 normal healthy children as controls.The plasma levels of TFPI were measured by enzyme linked immunosorbent assay in both groups.Forty-six HSP children were divided into 2 groups randomly:heparin therapy group(n=23)and conventional therapy group(n=23).The plasma levels of TFPI were measured before therapy,on the 7th day and the 14th day after therapy,respectively.Results 1.The plasma levels of TFPI in HSP group [(59.337?21.750)?g/L] significantly decreased than those of control group [(88.761?12.214)?g/L](t=7.185 P

Objective To explore the molecular mechanisms involved in hypokalemic salt-losing tubulopathies ( SLTs) through genetic screening of WNK gene in patients with SLTs. Methods Forty-four kindreds of SLTs were diagnosed Batter's syndrome or Gitelman's syndrome after CLCNKB and SLC12A3 sequencing and analysis, 8 of whose phenotype can not be simply attributed to CLCNKB or SLC12A3 mutations. Primers for PCR-amplified exons of WNK4 and WNK1 gene in genomic DNA were designed, and direct sequencing was performed to analyse the PCR products. Results Two missense mutations of WNK1, Ile~(1172)→ Met (I1172M) and Ser~(2047) → Asn (S2047N), were identified. Both of these 2 mutations segregated with the disease in SLTs kindred. Conclusion Two heterozygote missense mutations of WNK1 gene (I1172 M and S2047N) were found in 8 SLTs kindreds, indicating that WNK1 might be another gene responsible for hypokalemic salt-losing tubulopathies.
