1.Study on the expression change of HIF-1α and VEGF in protein levels and the correlation of them in QBC939 cell line under chemical hypoxia induced by CoCl2
Cancer Research and Clinic 2009;21(6):368-370
Objective To examine the expression change of HIF-1α and VEGF in protein levels and the corelation of them in Q8C939 cell line under chemical hypoxia induced by CoCl2 in vitro. Methods ELISA and immunohistochemical technique were used to examine the change of VEGF and HIF-1α protein level in QBC-939 line in different concentrations (200, 150, 100, 50, 0 μmol/L) of COCl2 and different periods (6 h, 12 h, 24 h, 48 h) in hypoxia. Results CoCl2 can up-regulate the expression of HIF-1α and VEGF at least partly in a dose and time dependent pattern. ELISA demonstrated that the level of VEGF protein in different concentrations and different hypoxia periods, the result showed that the VEGF protein was in different concentration groups over contrast group (P<0.05). The VEGF protein also increased continuously with the growing of hypoxia time (P<0.05). Immunohistochemical detection of concentrations of different groups, HIF-1α, VEGF protein in the average gray compared with the control group was different(P<0.05). Different time periods of hypoxia HIF-1α, VEGF protein in the average gray, any two group comparisons have difference (P<0.05). Different concentrations, the normal control group, different time period HIF-1α and VEGF protein expression of relevance were analyzed. The correlation coefficient was 0.830, P <0.01, 0.909, P <0.01. Conclusion In QBC939 cell line of hypoxia, there is up-regulation HIF-1α and VEGF.HIF-1α regulated the expression of VEGF.
2.Study on the relationship between red blood cell distribution width and short term prognosis in patients with acute coronary syndrome
Clinical Medicine of China 2010;26(5):482-484
Objective To evaluate the correlations of red blood cell distribution width (RDW) and short term prognosis of patients with acute coronary syndrome.Methods 179 patients with acute coronary syndrome (ACS) treated in our hospital between Jan.2008 to Apr.2009 were grouped by cutoff value of 14.4%.The incidence of acute myocardiac infarct( AMI),malignant arrhythmia,heart falure,sudden cardiac death(SCD) were compared in the two groups when patients were hospitalized and in half years of discharged.High-sensitivity C-reactive protein.(hs-CRP) ,BNP were also compared between the two groups.Results The incidences of cardiac adverse event were different between the two groups(AMI:39.47% vs.15.53% ,HF:22.22% vs.6.80% ,SCD:9.21% vs.1.94% and malignant arrhythmia:11.84% vs.3.90%,P values all less than 0.05 ).hs-CRP were ( 9.44 ± 8.03 ),(4.64 ±4.42) mg/L and BNP were (357.07 ± 161.60),(233.17 ± 134.76) ng/L in the two groups ( P < 0.05 ).RDW is positively correlated with hs-CRP and BNP (r is 0.42 and 0.58 respectively,P-value all less than 0.05).Conclusions The RDW is related to the short term progonosis in patients with ACS,and also positively correllated with plasma hs-CRP and BNP levels.
5.The drug resistance mutation detection and relevant factors analysis of HBV P region in chronic hepatitis B patients in Weifang City, Shandong Province.
Chinese Journal of Virology 2015;31(1):14-17
In order to investigate the mutation of HBV polymerase gene reverse transcription conserved region (P region) in chronic hepatitis B (CHB) patients, 212 CHB patients who took antiretroviral treatment with nucleotide analogues were chosen. The drug resistance mutations of HBV P region and HBV genotype were detected by Pyrosequencing. Sequence analysis showed that the drug resistance sites of HBV P region located at sites 173; 180; 181; 184; 204; 236 and 250. The main site of HBV P region drug resistance was 204 and 180, accounting for 35.8% and 23.5%, respectively. There were significant differences in the mutation rate of site 180 among different age groups. There were also significant differences in the mutation rate of site 204 among younger than 30 age group, 41 to 50 age group and 51 to 60 age group. (P < 0.05, P < 0.01). The mutation rate of site 180 combined with site 204 was 66.6%. The mutation rate of site 181 combined with site 236 was 23.3%. The age of C genotype infected patients was significantly older than B genotype infected patients (P < 0.01). M204V/I mutation mostly existed in the form of joint L180M mutation, the mutation rate was age-related. The detection of HBV genotypes and drug resistance sites of HBV P region have important clinical implications for the treatment and prognosis of patients with CHB.

6.Application of responsibility system for holistic nursing in high-quality nursing service in the department of respiratory medicine
Chinese Journal of Practical Nursing 2013;(3):71-73
Objective To evaluate the application efficacy of responsibility system for holistic nursing system in high-quality nursing service in the department of respiratory medicine.Methods Department of respiratory medicine unit which was the quality nursing service demonstrated unit in our hospital was selected.The nursing responsibility-bound grouping system was first performed and the nurse-incharge would provide the patients with whole and continuous nursing service.Before and 6 months after the application,the nursing job satisfaction was conducted and the nursing grouping system satisfaction was also evaluated among nurses and doctors.Results Six months after the application of nursing responsibility-bound grouping system,the patient satisfaction with nursing job was raised obviously in the unit.Conclusions The application of responsibility-bound grouping system can not only promote the activity but also mobilize the enthusiasm of nurses,and then high-quality nursing service was resulted.So the service system was worthy of clinical application.
7.Expression of c-myc, c-myb and c-erbB-2 protein in breast cancer
Chinese Journal of Primary Medicine and Pharmacy 2013;20(5):641-643
Objective To investigate the roles of aberrant expression of c-myc,c-myb,and c-erbB-2 in the development of breast cancer and its clinical significance.Methods Immunohistochimical technique (S-P method)was used to detect the expression of c-myb,c-myc and c-erbB-2 protein in 150 cases of breast cancer and 30 cases of benign proliferative lesions.heir relation to clinical pathological parameters were analyzed.Results The protein expression levels of c-myc,c-myb,and c-erbB-2 in breast cancer were higher than those in benign proliferative lesions and the difference was significant(all P <0.05).Expression of c-myc protein had obvious relationship to histological grade,lymph nodes metastasis and pathological types(all P < 0.05).Expression of c-myb protein related significantly to histological grade (P < 0.05).c-erbB-2 was associated with the tumor size,grading,PR expression (all P < 0.05).The association among the three kinds of genetic proteins was observed.Conclusion Expressions of oncogenes c-myc,c-myb,and c-erbB-2 proteins are higher in breast cancer and lower in benign proliferative lesions.The difference is significant.They are related to the grading and some other prognostic factors such as tumor size,pathologic types,PR expression and lymph node metastasis.The results suggest that these oncogenes are activated in the development of breast cancer and provoke cancerous cells multiplication.Expressions of oncogenes c-myc,c-myb and c-erbB-2 mightbe considered to be the prognostic indicators of breast cancer.
8.The value of ~(18)F-FDG PET and ~(18)F-FDG PET/CT in clinical evaluation of sarcoma
Tumor 2010;(3):253-256
As a functional imaging method, positron emission tomography (PET) is widely used in tumor diagnosis, pathological classification, stage assessment, and clinical outcome evaluation. Combination of metabolic information acquired from ~(18)F-fluorodeoxyglucose (~(18)F-FDG) PET with pathological grading results is helpful for further defining the grade of sarcomas and predicting prognosis. ~(18)F-FDG PET appears to be superior to other imaging modalities in detecting bone metastases or pulmonary metastases of sarcoma patients, so it could be used in clinical staging and restaging of sarcoma. Tumor-to-background ratio (TBR) and standardized uptake value (SUV) are two important parameters for quantitative analysis and are helpful for assessing chemotherapy response of tumor. PET imaging offers important information to help maximize the clinical benefit of patients with sarcoma. This article reviews the clinical value of ~(18)F-FDG PET and ~(18)F-FDG PET/CT in diagnosis of sarcoma.
