ObjectiveTo evaluate the diagnostic performance of bone SPECT and CT fusion imaging in bone metastases from pediatric neuroblastoma.MethodsTwenty-four pediatric patients with neuroblastoma were included in this retrospective study.All patients underwent planar imaging and SPECT integrated with CT.Lesion visibility,diagnostic certainty and diagnostic performance were evaluated with KolmogorovSmirnov test andx2 test.ResultsLesion visibility of SPECT alone,SPECT integrated with CT were significantly better than that of planar imaging ( both H =69.000,P ＜ 0.05 ).SPECT and CT fusion imaging,SPECT alone both detected five more bone lesions than planar bone imaging (77 vs 72).The diagnostic accuracy of SPECT imaging (62.34％,48/77 )was significantly higher than that of planar imaging (45.45％,35/77; x2 =4.416,P ＜ 0.05 ).The sensitivity,specificity and accuracy of SPECT and CT fusion imaging for diagnosing malignant bone lesions were significantly higher than those of planar imaging:82.35％ (42/51) vs 53.19％ ( 25/47),88.46％ ( 23/26 ) vs 40.00％ ( 10/25 ),84.42％ ( 65/77 ) vs 45.45％ (35/77 ; x2 =12.571,14.016,25.667,all P ＜ 0.01 ).The diagnostic specificity and accuracy of SPECT and CT fusion imaging were significantly higher than those of SPECT alone ( 53.85％,14/26 ;62.34％,48/77) (x2 =7.589,9.606,both P ＜0.01 ).However,there was no significant difference of sensitivity between the two methods (x2 =2.942,P ＞ 0.05 ).Diagnostic certainty by SPECT and CT fusion imaging was significantly higher than that by SPECT alone ( H =28.000,P ＜ 0.05 ) and by planar imaging (H =21.000,P ＜ 0.05).ConclusionSPECT and CT fusion imaging can detect more bone lesions in patients with pediatric neuroblastoma.It is helpful for diagnosing bone metastases from pediatric neuroblastoma.

Objective To evaluate the effect of the intervention of involving clinical pharmacists in perioperative total parenteral nutrition (TPN) prescription,including rationality of prescriptions,the length of hospital stay and economic evaluation.Methods We respectively selected TPN prescriptions in September to November 2015 (pre-intervention) and December 2015 to February 2016 (post-intervention) from a surgery department of Harbin Medical University Cancer Hospital.The data regarding rationality of prescription,length of hospital stay,and economic benefit were analyzed in order to evaluate the effect of involvement of clinical pharmacists in TPN prescriptions.Results A total of 81 patients with 115 TPN prescriptions before the intervention and 92 patients with 124 TPN prescriptions after the intervention were recruited.Through comparative analysis,the rationality of TPN prescriptions increased significantly after the participation of clinical pharmacists in terms of the rational glucose:fat ratio,energy:nitrogen ratio,electrolyte concentration,and the choice of vitamin preparations;and the utilization of controversial treatments such as invert sugar and other drugs into readyto-use TPN solution was decreased significantly;average daily cost of TPN was decreased from (1 021 ± 218) yuan to (860 ± 176) yuan (P ＜0.001);average duration of hospital stays was decreased but the difference was not statistically significant (P ＞ 0.05).Compared with the data before the intervention,serum albumin levels after the intervention showed no statistically significant difference but pre-albumin levels were significantly higher after the participation of clinical pharmacists [(175.0 ± 77.9) g/L vs.(153.2 ± 64.8) g/L,P ＜ 0.05].The liver and kidney function indicators showed no statistically significant differences between pre-and post-intervention (P ＞ 0.05).Conclusion Engaging clinical pharmacists in TPN prescription can improve prescription rationality,ensure clinical drug safety,reduce the daily cost of nutrition treatment and thus reduce the economic burden of patients.

OBJECTIVE:To investigate thinking and working skill of clinical pharmacist working in the tumor hospital. METHODS:Medical care can be improved by strengthening theoretical learning and clinical practice,exploring thinking and skill in the working. RESULTS:The way that clinical pharmacists participated in the treatment can improve the curative effect and reduce incidence of ADR. CONCLUSION:Clinical pharmacists should direct medication according to patients’condition to guarantee safety and effectiveness of drug use.

Objective To understand and raise the level of osteopomsis-relied knowledge, attitudes and behaviors for prevention and treatment of osteoperosis(OP)in residents of a community. Methods A survey was performed with a questionnaires method targeting at the elderly residents in Changfeng community.The survey was conducted with a specifically designed questionnaire,followed by a second survey.during which health edueafion was stressed.Data were analyzed with SPSS 11.0 software. Results In 3524 residents.3367 responded positively.The ratio of male to female was 1:2.10.The average age of the respondents was 61.34 years.They demonstrated a low level of OP KAP.76.72% of them heard the term of OP,60.11% had a correct judgment of their own bone heahh,42.26% knew the cause of OP.and 37.75% understood the diagnostic method of OP.The level of OP KAP varied in different groups of targeted residents.Of all the questions.the understanding of the diagnosis ranked the lowest.2281 people participated in the second survey,which showed improvement in their OP KAP.The difference was statistically significant.1439 people auended the consultation.99.86% of them considered the activities necessary,96.92% expressed their satisfaction,and 98.54% planed tO take measures to improve their bone health.Conclusion The poor understanding of bone heaith status and the knowledge about prevention and treatment of OP is why it is widely spread in the modem society,which however Call be improved by education.

Objective:To investigate the neuropsychological characteristics of Chinese agraphia caused by basal ganglia(BG)infarction.Methods:The writing abilities of 40 patients with BG infarction were detected by Chinese agraphia battery(CAB),and all the writing scores and agraphia quotient were calculated.The head CT/MRI images in agraphia and non-agraphia groups were standardized,the infarction were revealed and the superposition of two-dimensional arrays were performed,so that the central tendency of infarction was visually displayed.Results: Among the 40 patients,21 had left BG infraction,and 17 had agraphia;19 had right BG infraction,and 4 had agraphia.The two-dimensional superimposing neuroimages showed that BG infarctions caused agraphia was mostly in the left BG,including the left putamen,the head and body of the caudate nucleus,but there were fewer infarctions in the right putamen and the body of the candate nucleus.BG infarction caused agraphia was mostly aphasic agraphia,which was characterized by the orthographic disorders,paragraphia,and grammar mistakes.Conclusions: BG infarction may result in aphasic agraphia,which suggested that BG is involed in writing and processing,and it is the subcortical center of this advanced neurofunction in writing.

Objective To simulate the mechanical environment of cells in vivo and study cellular signal transduction mechanisms. Methods A device was developed which could provide high cell yield, control the time, strain magnitude, direction and frequency of stretch, and applied 10% cyclic strain to cell culture substrate with stretch frequency at 1Hz. Results After being stretched, morphology and cytoskeleton of cells were altered. The major axis of cells and the alignment of stress fibers were vertical to the orientation of cyclic stretch. Conclusion This device provides versatile options for the study on the cellular responses of mechanical loading.
