Objective To compare three kinds of double-dosimetry algorithms used in estimating interventional radiology worker's effective dose.Methods TLDs were put in the Alderson Radiation Therapy Phantom (ARTP) dressed with lead apron,lead cap and lead collar.TLDs were put on the front left chest inside the lead apron and on the left outside lead collar,respectively.Radiation scattering models,intensity-modulated radiotherapy body model at one time and CT dose detection model at another time,were put on the operating table.The ARTP was set at the major operator's position exposed to the Xray,mimicking the real interventional radiology operation.Effective doses were estimated on the basis of organ absorbed doses.Effective doses were also obtained by the use of three kinds of double-dosimetry algorithms.The later three effective doses were compared with the first one.Results Two groups of effective doses were obtained,with each including four data.For intensity-modulated radiotherapy body model,effective doses were 0.138 mSv for phantom method,0.097 mSv for NCRP algorithm,0.161 mSv for Niklason's algorithm and 0.173 mSv for Boetticher's algorithm,respectively.For CT dose detection model,effective doses were 0.018,0.013,0.019 and 0.026 mSv,respectively.The result obtained by using the Niklason's algorithm was the closest to that by using phantom method.Conclusions Niklason's algorithm is more accurate and more practical in eatimating interventional radiology worker's effective dose.

Objective To explore quality of life (QOL) of spouses of spinal cord injury patients,as well as its influencing factors.Methods Sixty-eight spouses of spinal cord injury patients were recruited as an observation group.At the same time,another 70 healthy married people who had no serious chronic diseases in the family but were matched in gender,age,occupation and education were chosen as a control group.The QOL of all the subjects in both groups was investigated by way of a questionnaire survey.The results of both groups were compared and factors that influenced their QOL were explored.Results The QOL of spouses of spinal cord injury patients,including total QOL ( 3.22 ± 0.37 ),physiological function ( 60.57 ± 14.22 ),psychological state ( 60.09 ± 8.06 ),social relations (63.37 ± 8.10 ) and the living environment (66.86 ± 11.26 ) were significantly lower than in the control group (4.62 ± 0.75 ; 82.48 ± 10.92 ; 86.02 ± 8.75 ; 85.94 ± 10.13 and 83.23 ± 9.54,respectively).The QOL of spouses of spinal cord injury patients was closely related to the patient's injury type,injury position,the treatment protocol,as well as their own gender,vocation and education.Conclusion The QOL of spouses of spinal cord injury patients is significantly lower than that of normal people,and closely related with the patients' injury type,injury position and treatment,as well as their own gender,vocation and education.

Objective To explore the expression of BID protein and the relation ship of cell proliferation with apoptosis at different stages of IgAN.Methods The expression of BID protein、PCNA and FN in renal tissue was detected by immunohistochemistry,TUNEL and light microscopy were used to detect apoptotic cells.Results With the progress of IgAN,the expression of BID protein、PCNA、the number of apoptotic cells and FN increased gradually(P

Objective To investigate effects and safety of dexmedetomidine on the prevention of abnormal mental in patients after liver transplantation.Methods 160 patients after liver transplantation were randomly divided into the two groups using the drawing method:midazolam group(n =80),dexmedetomidine group(n =80),compared the two groups of patients with general,mental abnormality and the occurrence of adverse reactions.Results There were no significant differences in the general situation (gender,age,postoperative ventilator time,ICU stay time,oper-ation time,blood FK506 concentration,APACHEII score 24 hours after operation)of the two groups of patients (P >0.05),the spirit of the abnormal rate of the observation group was lower than that of the control group (P =0.009), incidence of hypotension and hypertension in the observation group was higher than that in the control group (P =0.035,0.029).Conclusion Dexmedetomidine can effectively reduce the postoperative mental disorders in patients in the early stage after liver transplantation.

Objective To explore the expression and significance intergrin alphavbeta3(art33)in the kidney of patients with IgA nephropathy(IgAN).Methods lmmunohistochemistry wag applied to detect the expression of avl33。fibronectin(Fn)and Connective tissue growth factor(CTGF)in the kidney of patients with IgAN.and correlation analysis was done with pathology and clinic index.Result With the development of the disease,the expression of etvl33 was gradually increased in the glomemlar capillary endothelial cell.and mesansial cell as well as glomerular crescent.The positive area ratio of αvβ33 in renal glomerulus was(16.18±o.98,19.58±0.99,28.35±1.99,17.72±2.17)％respectively in grade I～Ⅳ pathological changes.Among all the groups,the expression of αvβ33 was the strongest in grade Ⅲ,while decreased in grade Ⅳ(P

Objective To study the impact of psychological care and health education on patients with digestive tract cancer and abnormal emotion receiving chemotherapy. Methods A retrospective analysis was carried outin 245 patients with malignant digestive tract cancer from July 2005 to July 2009 treated in our hospital, 147 cases of these patients received psychological care and health education besides conventional therapy were set as the intervention group, 98 cases given only basic nursing care were set as the control group. The clinical efficacy was analyzed in the two groups before and after chemotherapy using anxiety and depression indexes as indicators. Results After chemotherapy, SAS and SDS scores were significantly lower, while the survival time was significantly higher in the intervention group than those of the control group. Conclusions Psychological care and health education can reduce abnormal emotion in patients with malignant digestive tract cancer receiving chemotherapy and prolonged their survival time.

Objective To measure the thickness of the iliotibial band(ITB)in normal adult volunteers and to evaluate the value of ultrasonography in the diagnosis of ITB injury.Methods Ultrasonography was used to measure the thickness of the ITB in 20 normal adult volunteers,which were compared with the sonographic findings in 11 patients with iliotibial band friction syndrome(ITBFS).Results The thickness of the ITB in normal volunteers was(1.55±0.40)mm at the level of the femoral condyle and(2.05±0.30)mm at the insertions of tibial tubercle(Gerdy's tubercle).There were no significant differences between the right and left sides.In each of 11 patients with ITBFS,there was a more ITB thickness in symptomatic side than that of asymptomatic side(more than 30% in the difference between two sides).The ITB had a area of decreased echoginicity in symptomatic side.The thickened position of ITB were at insertion resion in 6 cases,at the level of femoral condyle in 3 cases and diffuse in 2 cases.Bursa fluid were found in 4 cases.Conclusions Ultrasonography can effectively evaluate the degree and range of ITB injury,and can give important information for clinical theraphy.
