AIM: To study the preconditioning effect of nitrate medicine on different parts of the heart and its signaling pathway. METHODS: The cells from different parts of the heart (atrium, left ventricle, right ventricle, apex and the whole heart) were isolated and cultured. The cultured cells were treated with hypoxia and reperfusion, hypoxia preconditioning, 1 mmol/L L-arginine preconditioning and 5 mmol/L L-arginine preconditioning, respectively. The cell necrosis rate, cell apoptosis rate, LDH concentration in the medium, the [Ca 2+]i and PKC activity in the cells were determined. RESULTS: The result show that hypoxia and reperfusion increased the necrosis rate and apoptosis rate, enhanced the concentration of LDH in the medium and the [Ca 2+]i overload in the cells (P0.05). After hypoxia preconditioning and L-arginine preconditioning, these indexes decreased (P

Objective To explore the X-ray radiation dose to patients from different cardiovascular interventional procedures and analyze the dose-affecting factors.Methods In accordance with the A,B,C operators,442 patients undergoing cardiovascular interventional procedures were collected,including single coronary angiography (CAG),percutaneous coronary intervention ( PCI ),radiofrequency catheter ablation (RFCA),congenital heart disease intervention (CHD) and permanent cardiac pacemaker implantation (PCPI),to observe dose area product (DAP),cumulative radiation dose (CD),fluoroscopy time.Results CD values of patients in groups of CAG,PCI,RFCA,CHD,PCPI were (0.34 ±0.23),(1.33 ±0.76),(0.71 ±0.43),(0.27 ±0.22) and (0.92±0.42) Gy and DAP values were (34.18 ±23.33),(135.92 ±81.14),(79.79 ±50.66),(27.93 ±23.66),and (94.60 ±48.11 ) Gy·cm2,respectively.Fluoroscopy time were (4.82 ±3.73),( 16.64 ±9.01 ),( 17.04 ± 15.29),(9.60 ±5.97)and (7.31 ±6.45) min.DAP values and fluoroscopy time were highly correlated (r =0.84,P < 0.05 ).Conclusions There is significant difference in radiation dose for cardiovascular interventional procedures.Radiation dose and fluoroscopy time are directly related to surgeons' proficiency in operations.Improvement of operation proficiency should be carried out to reduce the patients' radiation dose.

Objective To explore the relationship between work-family conflict and turnover inten-tions in nurses and find out the key points to reducing turnover intentions by releasing individuals' work-family conflict. Methods Cross-sectional study method was used in this investigation. By using cluster sampling method, 1287 nurses from some top-level and third-class general hospital were investigated. The questionnaire of work-family conflict and turnover intentions scale were used in this research and the re-suits underwent analysis. Results The score of turnover intentions in nurses was positively correlated with the level of their work-family conflict (r=0.233,P<0.01). Stress,behavior and time dimension were related factors of turnover intentions(r=0.243,0.191,0.176,P<0.01 ).After control of demographic factors, the turnover intentions deviation that can be explained increased by 7%. Conclusions The score of work-family conflict is one of the predicators of turnover intentions. A developing measure should be taken to reduce turnover intentions by releasing work-family conflict in nurses.

Objective To identify the sounces of occupational stress and explore the relationship between occupational slreas and social support for nurses in ICU.Methods A descriptive and correlation design was used in this study.From July to October in 2007,159 nurses from 8 ICU and 160 nurses from common wards completed the questionnaires.Statistical analysis was performed for the investigation results.Results The ayes age score of occupational stress for nurses in ICU was (3.41±0.73),which was in a moderate to high level.The main stress was that they regarded nursing as a high risk career,maximums working intensity,always overload work and frequent night-shift.While the average score of occupational stress for nurses in common wards was (3.29±1.05).The main stress was that they regarded nursing as a high risk career,Score of occupational stress between nurses in ICU and com wards had no statistical difference(P>0.05).There was a significant negative correlation between occupational stress and social support for nurses in ICU(r=-0.159,P<0.05).And the sup port by friends was into the equalion by multi-linear regression.Conclusions The level of occupational stress for murses in ICU was fairly hish.Scientific management of human resource,reducing work pressure of nurses and workloed,exerting various social support will benefit for reducing the stress of nurses in ICU.

BACKGROUND:Ischemia microenvironment contributes mostly to the low survival rate of rat bone marrow mesenchymal stem cells after transplantation. Hydrogen sulfide (H2S) can protect various cells and tissue models against apoptosis and injury.
OBJECTIVE:To detect the cellapoptosis and viability, content of H2S in supernatant, and the expression of H2S synthetase after different time of hypoxia and serum deprivation cultivation of rat bone marrow mesenchymal stem cells.
METHODS:The passage 3 rat bone marrow mesenchymal stem cells were divided into five different cultivation time groups:0-, 3-, 6-, 12-and 24-hour groups. After enough hypoxia and serum deprivation cultivated time, the cellapoptosis was detected by SubG1, the cellviability was determined by cellcounting kit-8, the content of H 2S in supernatant was measured by N,N-dimethyl-p-phenylenediamin and the expression of H2S synthetase by RT-PCR and western blot.
RESULTS AND CONCLUSION:Compared to the normal cultivation group, after different hypoxia and serum deprivation cultivated time, the cellapoptosis increased and cellviability decreased significantly. The longer hypoxia and serum deprivation cultivated time caused the more cellapoptosis and the lower cellviability. The contents of H2S and its synthetase were also suppressed by hypoxia and serum deprivation cultivation. The difference was statistical y significant. These findings suggest that hypoxia and serum deprivation cultivation can inhibit the generation of H 2 expression of its synthetase.

OBJECTIVE: To investigate the effects of tetrandrine (Tet) on nuclear factor kappaB (NF-kappaB) expression in leukemia cell line K562 and multidrug-resistant K562/A02 cell line. METHODS: The activations of NF-kappaB in K562 and K562/A02 cells and the effects of 1 micromol/L Tet on NF-kappaB expression were determined by immunocytochemistry and Western blot assay. RESULTS: Tet had no effect on NF-kappaB expression in K562 cells after 6- and 12-hour treatment (P>0.05), and K562/A02 cells displayed higher level of NF-kappaB protein expression than their parental K562 cells (P<0.01). Tet could significantly down-regulate NF-kappaB protein expression and nuclear translocation in K562/A02 cells shown by immunocytochemistry and Western blot, and this decrease became more significant after 12-hour treatment than after at 6-hour treatment (P<0.05). CONCLUSION: Activation of NF-kappaB may be related to multidrug resistance of K562/A02 cell line. And the inhibition of NF-kappaB activation by Tet leads to multidrug resistance reversal in K562/A02 cell line.

OBJECTIVE:
To determine the correlation between p16 gene CpG methylation sites in the promoter region and HPV16 infection in cervical squamous cell carcinoma in Xinjiang Uyghur women.
METHODS:
MALDI-TOF MS was used quantitatively to analyze p16 gene promotor methylation status of CpG islands in 20 cervix squamous cell carcinomas and 20 corresponding non-cancerous tissues in Uyghur women. HPV16 infection was detected by polymerase chain reaction (PCR) in both groups.
RESULTS:
Among the 16 CpG sites in the p16 gene promoter region, CpG1-2 and CpG 6 sites were different between the 2 groups, and the levels of CpG1-2 and CpG6 methylation sites in the cervical squamous cell carcinoma were higher than those in the control group. The presence of HPV16 infection was significantly different between the cervix squamous cell carcinoma tissue and non-cancerous tissues (P<0.05). There was no significant correlation between p16 gene CpG methylation sites and HPV16 infection of cervical squamous cell carcinoma in Uyghur women.
CONCLUSION
P16 gene CpG 1-2, CpG 6 hypermethylation and HPV16, which are independent of one another, play an important role in cervical squamous cell carcinogenesis in Uyghur women.
