Objective To investigate the gender differences of coronary heart disease secondary prevention status in patients post percutaneous coronary intervention (PCI). Methods Patients diagnosed with coronary heart disease from 31 tertiary hospitals were enrolled for a baseline survey. Medical history and laboratory tests were taken. Analysis was done for outpatient or inpatient with the history of at least one PCI treatment. Status of smoking cessation, weight management, blood pressure < 140/90 mm Hg, low-density lipoprotein cholesterol (LDL-C) < 100 mg/dL (2.6 mmol/L), and use of antiplatlet drugs, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARB) and statins were collected and compared. Results Women (n=1151) accounted for 25.4% of all PCI patients (n=4532). Proportion of female with history of smoking was signiifcantly lower than male, but the proportion of quitting was similar between female and male, 53%(n=98) vs. 53.7%(n=1344), P=0.849. The average body mass index, mean waist circumference and proportion of overweight were higher in man than women, P=0.000. However, the proportion of abdominal obesity in women is higher than men, 75.2%vs. 52.8%, P=0.000. More female were comorbid with hypertension, hyperlipidemia and diabetes than male and the differences were signiifcant, P=0.000. Control rate of blood pressure, LDL-C and fasting glucose were lower in women than in man, the differences were 66.2% vs 73.4% for blood pressure, 47.8%vs. 57.0%for LDL-C and 57.5%vs. 62.7%for fasting glucose, P=0.000. There was no signiifcant difference in medication usage between different genders. Conclusions In patients post pecutaneous coronary intervention, female patients had more risk factors than male while risk factor control rate was lower comparing with male. Medication usage for coronary heart disease secondary prevention was similar between different genders.

Objective To evaluate the expression of RAR-? gene in cervical carcinoma cell lines SiHa,HeLa,C33A and Caski and to analyze the relation between their gene expression and the promoter methylation of RAR-? DNA.Methods The expression of mRNA and protein of RAR-? gene in the four cell lines were analyzed by RT-PCR,western blot and immunofluoreseence,respectively.Methylation specific PCR(MSP)was used to check whether there was methylation in the promoter of RAR-? gene.The demethylating agent 5-aza-2'-deoxycytidine(5-Aza-cdR)was used to treat methylated cell lines and the change of RAR-? gene methylation and RAR-? gene expression defects were observed.The cell proliferation was assayed with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method.Results The mRNA and protein expression levels of RAR-? in cell lines SiHa,HeLa,Caski and C33A were 0.25 ?0.08,0,0.60?0.19,3.12?0.92 and 0.23?0.07,0,0.14?0.05,0.68?0.21,respectively.The mRNA and protein expression of RAR-? in SiHa,HeLa and Caski cell lines were decreased or silenced, whereas its expression increased in C33A cell line.MSP method showed that there were RAR-? gene methylation in SiHa,HeLa and Caski cell lines,while there was no RAR-? gene methylation in C33A cell line.After treated with 5-Aza-cdR,the mRNA and protein expression levels of RAR-? in SiHa,HeLa, Caski and C33A cell lines were 1.82?0.59,2.13?0.62,1.67?0.43,2.95?0.89 and 0.69?0.21, 0.83?0.29,0.56?0.16,0.64?0.20 respectively.The mRNA and protein levels of RAR-? had a significant difference between before and after interference with 5-Aza-cdR in SiHa,Helm,and Caski cell lines(P0.05).The 5-Aza-cdR treatment could suppress cell proliferation.Conclusions The RAR-? gene expression defects play an important role in the carcinogenesis of cervical cancer.Aberrant methylation in promotor region of RAR-? gene may be an important mechanism for the loss of expression of RAR-? gene.

OBJECTIVETo study the expression of p16 and nm23 genes in salivary gland tumors and the relation of P16 and nm23 proteins with fumorigenesis of salivary gland tumors.

METHODSExpression of P16 and nm23 proteins was examined by SABC immunohistochemical method in 39 cases of paraffin blocks of normal salivary gland tissues and salivary gland tumors.

RESULTSP16 and nm23 protein positive staining were mainly found in the cytoplasm and cytoblast of all salivary gland tissues. Positive rate of P16 protein expression was 76.9% (10/13) and 40.9% (9/22) in benign and malignant salivary gland tumors, respectively. There was significant difference between P16 protein expression of benign and malignant tumors by chi 2 test (P < 0.05). mm23 protein positive staining was found in 84.6% (11/13) and 45.5% (10/22) of benign and malignant tumors respectively. The expression of nm23 protein in benign and malignant tumors was significantly different (P < 0.05). There was no correlation of the expression of P16 and nm23 in salivary gland tumors was found (P > 0.05).

CONCLUSIONp16 and nm23 genes may play an important role in different sides in salivary gland tumorigenesis and the reduce of the expression of p16 and nm23 genes may contribute to the generation of malignant salivary gland tumors.

Objective To investigate the evidence of the knowledge, attitudes and behaviors of nurses to prevent falls of inpatients and to analyze the correlation among them. Methods The self-designed questionnaire about knowledge, attitudes and behaviors of nurses to prevent falls of inpatients was used to investigate nurses from a hospital of Grade Ⅲ Level A in Beijing. Results Scores of related knowledge to prevent falls of these nurses were in a better level(standard score 88.25 ± 8.97); the scores of knowledge to prevent falls without walking aids were relatively higher ( standard score 98.08± 6. 44), and the scores of walking aids-using-knowledge were relatively lower(standard score 69.98 ± 25.29), attitude towards prevention of falls were neutral, and scores of behaviors to prevent falls of these nurses were in a better level(standard score 87.49 ±7.82). Positive correlation was shown among attitudes, knowledge and behaviors to prevent falls. (r =0.179、0. 200, P ＜0. 05), however,there were no correlation between scores of knowledge and behaviors to prevent falls. Work experience and scores of knowledge to prevent falls were negatively correlated (r= -0.191, P＜0.05 ). Scores of attitude to prevent falls showed significant difference between the group of nurses who had learnt knowledge to prevent falls and group of those who had never encountered falls ( P ＜ 0. 05 ). Good department atmosphere had a significant impact to nurses' knowledge and behaviors to prevent falls (P＜ 0.05 ). Conclusions Nurses had inadequate cognition of walking aids-using-knowledge; attitudes towards prevention of fall were neutral; they had appropriate acts to prevent the falls; good department atmosphere can enhance the behaviors of nurses to prevent falls.

OBJECTIVETo investigate the characteristic findings of an anomalous systemic arterial supply to the lung without the pulmonary artery on spiral CT and discuss its nomenclature.

METHODSFour cases of anomalous systemic arterial supply to the left basal segment of the lung without the pulmonary artery were retrospectively reviewed with analysis of the characteristic CT findings.

RESULTSOn spiral CT scans, the involved left lower lung including the entire left basal segments (n=2), the lateral and posterior basal segment (n=1), and the anterior, medial, and posterior basal segment (n=1) had mild volume loss and areas of ground-glass opacity but with normal bronchial trees. The absence of the entire or part of the basal segments of the normal left lower lobar pulmonary artery, anomalous systemic artery originating from the abdominal aorta, diffuse dilatation of the systemic arterial branches distributed in the basal segments of the left lower lobe, and left lower pulmonary venous drainage into left atrium were found in all these patients.

CONCLUSIONThis anomaly presents with characteristic findings on chest spiral CT, for which the nomenclature of local absent pulmonary artery better shows the characteristics of the disease.

BACKGROUNDMarked interindividual variation exists in blood pressure response to benazepril, which is considered to have genetic basis. Our objectives were to evaluate whether the E112D polymorphism in the prolylcarboxypeptidase (PRCP) gene has impact on blood pressure response to benazepril.

METHODSHypertensive patients from Huoqiu County and Yuexi County of Anhui Province received daily treatment with an oral dosage of 10 mg benazepril for 15 days. Genotypes of the E112D polymorphism in the PRCP gene were determined by TaqMan SNP genotyping assay. Multivariate linear and Logistic regressions using generalized estimating equation model were performed in a total of 1092 patients to evaluate the association of PRCP genotypes and blood pressure response to benazepril.

RESULTSPatients carrying ED or DD genotype had a less systolic blood pressure reduction (adjusted beta = -3.7 + or - 1.1, P < 0.001), a less diastolic blood pressure reduction (adjusted beta = -3.1 + or - 0.8, P < 0.001) and a lower percentage of reaching target blood pressure defined as SBP lower than 140 mmHg and DBP lower than 90 mmHg (adjusted OR = 0.6, P = 0.005) than those patients carrying EE genotype. In addition, the results from stratified analysis by county (Huoqiu or Yuexi) were similar to those observed in the pooled population.

CONCLUSIONSOur data suggest that the E112D polymorphism in the PRCP gene may be a useful genetic marker to predict the antihypertensive effect of short-term benazepril treatment in hypertensive patients of Anhui Province, China.

This study was aimed to screen human papillomavirus (HPV) types associated with esophageal squamous cell carcinoma of Kazakh in Xinjiang using the gene chip technique and study the clinical significance of this application. The DNAs were collected from esophageal squamous cell carcinoma tissues and healthy esophageal mucosa of Kazakh adults in Xinjiang, and amplified firstly using HPV MY09/11 and then using HPV G5+/6+ to screen positive HPV specimens. These positive specimens were further detected by the gene chip technique to screen highly pathogenic HPV types. After determination with nested PCR amplification with HPV MY09/11 and G5+/6+, the infection rate of HPV was 66.67% in the esophageal squamous cell carcinoma group and 12.12% in the healthy control group. By testing the positive HPV specimens from the esophageal squamous cell carcinoma group, the infection rate of HPV16 was 97.72% and the co-infection rate of HPV16 and HPV18 was 2.27%. HPV16 infection may be involved in the development of esophageal squamous cell carcinoma in Xinjiang Hazakh adults.
