Objective To discuss the effects of nursing intervention under the guidance of health belief on enteroscopy compliance of colorectal cancer high-risk population. Methods A total of 260 people, who were clearly identified as colorectal cancer high-risk population during preliminary screening of 2 communities in Nankai District, Tianjin but had not finished enteroscopy, were selected and divided them into intervention group and control group with 130 people per group by random digits table method. In the intervention group, subjects received nursing intervention with guidance of the health belief model for a year, while in the control group, subjects simply received regular propaganda and education about colorectal cancer screening. Results After intervention, the cognitive levels in colorectal cancer screening, enteroscopy screening, high-risk factors was (9.16±2.95), (14.55±3.41), (14.25±4.26) points in intervention group and (7.28 ± 3.26), (12.23 ± 3.72), (13.12 ± 4.11) points in control group, and there was significant difference between two groups (t=4.855, 5.228, 2.180, P<0.01 or 0.05). After intervention, the scores of health belief including susceptibility, benefits, barriers, self-efficacy was (7.74 ± 1.50), (13.20 ± 2.45), (6.59 ± 1.91), (23.54±3.16) points in intervention group, and (6.68 ± 1.47), (11.58 ± 2.15), (8.42 ± 1.99), (20.82 ± 3.02) points in control group, and there was significant difference between two groups(t=5.730, 5.682,-7.561, 7.096, P<0.01). The rate of enteroscopy screening was 20.47%(26/127) in intervention group and 8.87%(11/124) in control group, and there was significant difference between two groups(χ2=6.719, P<0.05). Conclusions The nursing intervention under the guidance of health belief helps colorectal cancer high-risk population establish health belief, enhances participation rates of colonoscopy screening and has important significance to positive rates of early colorectal cancer.

Purpose To investigate the diagnostic value of high-resolution CT reconstruction techniques on the same slice in hypertrophy of transverse process of the fifth lumbar vertebra (HTPL5V), and to provide a basis for clinical diagnosis and treatment. Materials and Methods Twenty-two cases of clinically diagnosed HTPL5V and 20 normal adults were examined with GE LightSpeed 16-slice spiral CT (36 cases) and Philips iCT 256-slice (6 cases). L5 transverse process and the fifth lumber nerve were reconstructed and observed on the workstations. Results In 22 cases of HTPL5V, there were 26 pseudarthrosis formation and 2 sides with L5 transverse process touching the sacral ala. In 28 sides the iffth lumber nerve traveled through false foramina of the HTPL5V including 6 cases of bilateral compression and 16 cases of unilateral compression. In 21 cases, the nerve was compressed by hyperosteogeny on 27 sides (96.4%) and 1 side due to stenosis (3.6%). On 25 sides (89.3%) the compressed nerves were curved in shaper. There was bulging and/or herniated lumbar disc on 9 sides in 7 cases (32.1%). Conclusion High-resolution CT reconstruction techniques can demonstrate the iffth lumbar nerve of HTPL5V and provide evidence for clinical diagnosis and treatment.

Objective To determine the maintenance and loss of Epstein-Barr virus (EBV) genome during the clonal expansion of the EBV-infected epithelial cells. Methods The epithelial tumor cell line, 293-EBV, in which the EBV genome was observed with green fluorescent protein (GFP) readout. After a dozen of passages, it contained cells with strong or weak GFP expression, and some with complete loss of EBV genome. The cell growth was then continuously observed under a confocal microscope. The cell dividing and GFP expression were also observed during the clonal expansion by being made into very low density. Results The cells moved around due to adherence and mobility, while the GFP expression remained unchanged in the undivided cells. The cells could form compact or loosen clones. The EBV genome easily persisted in those clones when cells were growing compactly. As the cell number increased, the GFP expression became weak or even died away at the sites of low density in the loosen clones. Conclusion EBV-positive epithelial cells are able to sustain the EBV genome during its clonal expansion. The cells maintain EBV genomes by passing them to the daughter cells after replication. When the cells unsuccessfully inherit the EBV genome, the daughter cells may lose them which is related to the low cell density as well as the epithelial environment.

Objective To study the association between endometrioid uterine carcinomas and metabolic syndrome (MS). Methods A retrospective study was conducted on 123 patients who were admitted in Department of Gynecology Oncology, Zhejiang Cancer Hospital (study group) and 90 healthy women (control group) with matching age from Jan. 2005 to Mar. 2009. The general conditions[including age, whether menopausal, body mass index (BMI)];the risk factors for MS [including waist circumference,fasting plasma glucose, triglycerides(TG), high-density lipoprotein (HDL) and systolic and diastolic blood pressure]were analyzed. The clinical stage, histological type, and pathology differentiated degree of study group with or without MS were also analyzed by univariate analysis and Cox proportional hazards models.Results (1) The univariate survival analysis shown that there were no significant difference with age in two groups[(54.3±0.6) vs. (54.2±0.9) years;P>0.05], while the rate of menopausal, BMI(≥25 kg/m~2), the cases coupled with MS, the size of waist circumference (> 80 cm), the level of fasting plasma glucose (≥5.6 mmol/L),TG(> 1.7 mmol/L)and abnormal systolic and diastolic blood pressure in study group were higher than those in control group (67.5% vs. 48. 9%, 45.5% vs. 23.3%, 43.9% vs.18.9%, 50.4% vs. 27.8%, 53.7% vs. 21.1%, 40.7% vs. 21.1% and 40.7% vs. 25.6%,respectively, all P <0.05). The percentage of HDL(< 1.30 mmol/L) was higher in study group than that in control granp(63. 4% vs. 32. 2%, P <0.05). (2) There were not significant difference for the clinical stage, pathological type, grades between patients with or without MS in study group (P > 0.05). (3) The Logistic multivariate survival analysis shown that central obesity, higher TG, lower HDL and abnormal plasma glucose were independent risk factors for endometrioid uterine carcinomas coupled with MS (P< 0.05). Conclusion Metabolic syndrome is marginally associated with an increased risk of endometrioid uterine carcinomas, which may be the new point to screen, prevention and treatment endometrioid uterine carcinomas.

To compare the effect of insulin glargine combined with nateglinide and continuous subcutaneous insulin infusion(CSII) during intraoperative period in type 2 diabetic patients with fracture. Both of the managements made blood glucose under control [fasting blood glucose(6.89±1.96)vs(6.75±2.33)mmol/L] in similar period [(3.6±1.6)vs(2.9±1.2) d,both P>0.05]. The mean blood glucose was lower in patients treated by CSII than that of the other group.

Objective To investigate curative effects of hypothermia on the secondary axotomy of nondisruptive axonal injury (NDAI) after diffuse brain injury (DBI).Methods A total of 16 male Sprague-Dawley rats were randomly and equally divided into hypothermia group (at 32℃ for 6 hours) and control group (at 37.5℃ ).The axonal swelling and axonal balls were detected by means of NF68kD immunochemistry after DBI caused by fluid percussion.The changes of maximal density of axonal swelling and axonal balls in callosum,diencephalon-mesencephalon,pons-oblongata and cerebellum were compared 24 and 72 hours after injury between both groups.Results NF68kD immunochemistry well showed axonal swellings and axonal balls in whole brain.The axonal swelling and axonal balls were significantly decreased 24 hours after DBI in both groups (P<0.05),especially in diencephalon-mesencephalon ,pons-oblongata and cerebellum (P<0.01).While there showed significant decrease of axonal swellings and axonal balls in pons-oblongata and cerebellum in hypothermia group 72 hours after DBI (P<0.05,P<0.01) but insignificant changes in the callosum and the diencephalon-mesencephalon compared with control group (P>0.05 ).Conclusions Hypothermia can retard the progress of mild or severe NDAI at early stage,which would taper with the longer time after injury except for partial mild NDAI.Hypothermia may prevent mild NDAI from secondary axotomy.
