18 F-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) and bone marrow biopsy (BMB) have high consistency in the detection of lymphoma bone marrow infiltration (BMI).18F-FDG PET/CT has a high sensitivity to Hodgkin lymphoma (HL) and aggressive non-Hodgkin lymphoma (NHL) BMI,while the sensitivity of indolent NHL is low.Since 18F-FDG PET/CT may appears false positive or false negative,so it can not replace the conventional BMB.We can carry out a BMB under the guidance of 18F-FDG PET/CT,which can greatly improve the detection rate of BMI.

Objective To investigate the pressures from night shifts among nurses from pediatrics department and find the countermeasures.Methods A self-designed questionnaire was used to investigate the pressures from night shifts among 112 nurses from pediatrics department as well as the reasons.Results 110 of the nurses(98.2%) assumed that the pressures from night shifts was intensive.The main reasons for the pressures came out of heavy workload,shortage of staff and stuff and the unsettled balance between job and family.Conclusion Such measures as reasonable distributions of nurses,abound supply of stuff and reduced working links may be effective for the alleviation of the pressures on nurses at night shifts,motivated activeness in them and then the enhancement of nursing quality.

Objective To explore effective methods of nursing quality evaluation. Methods Guided by human-centered thinking,the new DRG quality indicators were formulated based on clinical investigation,literature review and expert consulta-tion. Then,the standards of the new indicators for radical masteetomy were identified by Delphi method and the reliability and validity were tested in 30 patients with radical mastectomy. Results The two new quality indicators were illness observation and health education. The Cronbach'α was 0.82 and 0.88 respectively. The results of expert consultation showed high content validity. Moreover,the new quality indicators got high commend by involved nurses. Conclusion The new quality indicators will lead nursing work to illness observation and health education,which will more benefit to reflect the true work of nurses and improve the internal quality of nursing.

Objective To investigate effects of intrathecal methotrexate on mechanical allodynia in rats with tibial bone cancer pain.Methods Forty-eight female SD rats weighing 150-180 g were randomly divided into 6 groups ( n =8 each):group Ⅰ sham operation + artificial cerebrospinal fluid(SA group),group Ⅱ sham operation + methotrexate 200 μg(SM group),group Ⅲ bone cancer pain + artificial cerebrospinal fluid(CA group),group Ⅳ-Ⅵ bone cancer pain + different doses of methotrexate (CM1-3 groups).The model of tibial bone cancer pain was induced by injecting Walker-256 cell into the tibial marrow cavity.CA and CM1-3 groups were intrathecal injected artificial cerebrospinal fluid,methotrexate 50,100 and 200 μg.SA and SM200 groups were intrathecal injected artificial cerebrospinal fluid and methotrexate 200 μg.The mechanical withdrawl threshold (MWT) was measured at day 1 before Walker-256 injection (baseline),7 day after injection (T0 ) and 2,4,8,24 hour and 1,3,5,7 days after intrathecal injection ( T1-8 ).Results Compered with the baseline,MWT was decrease in CA and CM1-s groups.Competed with To,MWT was decreased at T5-8 in CA group,MWT was increased at T3-5 in CM1 group,at T2-6 in CM2 group and at T2-7 in CM3 groups.MWT was decrease in CA and CM1-3 groups as compered with SA group; MWT was increased at T4-7 in CM1 group and at T3-7 in CM2 and CM3 groups.Conclusion Intrathecal injection of methotrexate can reduce tibial bone cancer pain in rats.

Objectives To explore polymorphisms of CD152 gene promoters (-1722T/C,-1661A/G) and exon1 (+49A/G) in children with idiopathic ischemic stroke and assess the association between these polymorphisms with the disease. Methods Us-ing the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method, polymorphisms in the CD152 exon1 region (+49A/G) and promoter regions (-1722T/C,-1661A/G) were genotyped in 51 Han children with idiopathic ischemic stroke and 74 healthy Han children. Results The CD152 genotypes in control group and idiopathic ischemic stroke children were consistent to principle of Hardy-Weinberg Equilibrium (HWE) byχ2 test. The CD152+49GG genotypes and G allele frequency in the patients showed a signiifcant increase compared to the controls (χ2=7.053, 6.351, P<0.05). However, the CD152-1722T/C,-1661A/G genotypes and allele frequency showed no signiifcant difference between 2 groups (P>0.05). Clinical features (hemi-paresis, dysarthria, seizures, consciousness change, and preceding infections) did not show signiifcant correlation with genotypes and frequency of the CD152+49 polymorphisms in children with idiopathic ischemic stroke (P>0.05). Conclusions The CD152+49A/G polymorphisms may relate to idiopathic ischemic stroke.

Objective To investigate the role of chemokine ligand 21 (CCL21) in the spinal cord in tibia bone cancer pain (BCP) in rats.Methods Forty adult female SD rats weighing 160-180 g were randomly divided into 5 groups (n=8 each):sham operation group (group Ⅰ ); sham operation + CCL21 neutralizing antibody group (groupⅡ); BCP group (group [); BCP + PBS group (group Ⅳ); BCP + control IgG group (groupⅤ)and BCP + CCL21 neutralizing antibody group (group Ⅵ).BCP was induced by inoculating Walker-256 mammary gland carcinoma cells into the rat tibia medullary cavity in groups Ⅲ-Ⅵ.PBS 15 μl,IgG 10 μg and CCL21 neutralizing antibody 10 μg were injected intrathecally (IT) at 14 days after intra-tibial injection of Walker-256 mammary gland cancer cells in groups Ⅳ- Ⅵ respectively.Mechanical withdrawal threshold to yon Frey filament stimulation (MWT) was measured at 1 day before (To,baseline) ; 7 and 14 d after Walker-256 cell injection (T1,T2)and at 0.5,1,2,4,8,12,24 and 48 h after intrathecal injection (T3-10 ).Results Intra-tibial injection of Walker-256 mammary gland cancer cells significantly decreased MWT as compared with the baseline values in administration of CCL21 neutralizing antibody at T5-8 as compared with MWT before intrathecal administration at T2 in group Ⅵ.MWT was significantly lower in groups Ⅲ- Ⅳ than in groups Ⅰ and Ⅱ.MWT was significantly higher at T5-8 in group Ⅵ than in groups Ⅲ - Ⅴ.Conclu]sion CCL21 in the spinal cord is involved in the maintenance of tibia BCP in rats.

Objective To study and contruct competency characteristic evaluation models of nursing supervisors in secondly hospitals.Methods Using the matron semi-structured interviews,literature review,questionnaire survey and expert questionnaires to discuss the competency of nursing supervisors in secodary hospitals.Results We found that the competency model of nursing supervisors in secondary hospitals could better reflect the competency of nursing supervisors.The model had 16 competencies which included knewleage skills.management and individual characters.Conclusions Through the study of the model of competency nursing supervisors in secondary hospitals,we form a set of standard for nursing supervisor selection based on their competency.The standard can help to select the most suited nursing supervisors who have great potentials.

Objective To assess the efficacy and safety of levetiracetam (LEV) monotherapy in children with absence epilepsy.Methods Fifty five children [ 34 males,21 females,aged (8.1 ± 4.8) y ] with typical absence seizures were treated with LEV ( n =25 ) or valproic acid ( VPA,n =30) from Jan 2009 to Jun 2010.Patients were followed up for 1y; the seizure frequency,electroencephalogram (EEG) and side effect were observed at 6th month and 12th month after the initiation of therapy.Results During the follow-up,none had aggravated symptoms of epilepsy.There were no significant differences in seizure frequency(t =0.76,P =0.450; t =0.67,P =0.504),abnormal EEG ( x2 =0.120,P =0.729 ; x2 =0.043,P =0.836 ) and seizure control ( x2 =0.051,P =0.821 ; x2 =0.078,P =0.780) after 6 and 12 months of treatment between two groups.No death or severe side effects were observed; 2 cases (8.0％) in LEV group had mild adverse effect( drowsiness and restlessness)and 2 cases (6.7％ ) in VPA group had weight gain and nausea.Conclusion The results suggest that monotherapy with LEV is effective and safe for treatment of childhood absence epilepsy.

Objective:To investigate the clinical efficacy and action mechanism of abdominal acupuncture plus plum-blossom needle tapping for primary insomnia.Methods:A total of 66 eligible cases were randomly allocated into an observation group (n=33) and a control group (n=33). Cases in the observation group received abdominal acupuncture plus plum-blossom needle tapping, whereas cases in the control group received abdominal acupuncture alone. After 2, 6 weeks of treatment and 4 weeks after end of treatment, the patients in both groups were evaluated using the Pittsburgh sleep quality index (PSQI) and measure your medical outcome profile (MYMOP) based on the patients' self-report. Results:After 2 weeks of treatment, the total effective rate was 90.9% in the observation group, versus 63.6% in the control group, showing a statistical difference (P<0.05). After 6 weeks of treatment, there were no between-group statistical differences in total effective rate (P>0.05). After 6 weeks, the sleep quality and efficiency scores in the observation group were better than those in the control group. Four weeks after end of treatment, the scores of sleep quality and MYMOP in the observation group were better than those in the control group (P<0.05). Conclusion: Abdominal acupuncture plus plum-blossom needle tapping can obtain fast, accurate effect for primary insomnia and improve patients' sleep quality and efficiency.
