Objective To detect the expression of β-catenin in the tissues of primary central nervous system lymphoma (PCNSL), and to discuss its function in PCNSL.Methods The paraffin embedded tissues from 10 patients diagnosed as PCNSL from October 2010 to April 2012 were collected as the experimental group.The paraffin embedded tissues from 10 patients with lymphadenitis were collected as the control group.Quantitative real-time PCR and immunohistochemical method were used to detect the expression of β-catenin in these tissues, and the relationships between β-catenin and clinical data were analyzed.Results Immunohistochemistry results showed that β-catenin protein was localized in the cytoplasm and (or) nucleus.Among 10 PCNSL patients, β-catenin protein was positive in 4 patients, while it was no positive in all of 10 lymphadenitis patients, with the significant differences between both groups (P ＜ 0.05).The β-catenin gene relative expression level was 4.70±0.57 and 1.00±0.27 in the experimental group and the control group, respectively.β-catenin expression was no correlation to age, PS score, cerebrospinal fluid protein level and serum lactate dehydrogenase level of patients with PCNSL.Conclusions Whether in mRNA level or in protein level, β-catenin expression is always high in PCNSL tissues, and its protein is expressed in the cytoplasm, however, this phenomenon was not observed in the tissue of lymphadenitis.

Objective:To investigate the current status and related factors of psychological distress in tele-phone operators.Methods:Totally 575 telephone operators from sample of a convenient survey in a certain telecom-munication company of Shandong Province were selected.They were assessed with Kessler Psychological Distress Scale (K10),Connor-Davidson Resilience Scale (CD-RISC-10),Perceived Social Support Scale (PSSS)and Sim-plified Coping Style Questionnaire (SCSQ)for the evaluation of psychological distress,resilience,perceived social support and the coping style respectively.Ordinal logistic regression was used to identify the related factors of psy-chological distress.Results:The mean score of K10 was (24.7 ±6.7),91.8% (528 /575)of telephone operators had psychological distress.Specifically,24.5%(141 /575)had mild psychological distress,45.4% (261 /575)had moderate psychological distress,21.9% (126 /575)had severe psychological distress.Ordinal logistic regression a-nalysis indicated that the ones with good economic conditions (OR =1.74,95%CI:1.15 -2.63),higher level of re-silience (OR =1.13,95%CI:1.10 -1.17)and other social support (OR =1.07,95%CI:1.02 -1.12)had milder psychological distress;while with negative coping style (OR =0.29,95%CI:0.20 -0.41)had more severe psycho-logical distress.Conclusion:It suggested that the prevalence rate of psychological distress among telephone opera-tors is high.Poor economic conditions,lower level of resilience and social support,and negative coping style might be the related factors of psychological distress.

BACKGROUND AND OBJECTIVESkeletal metastase is one of the most common complications related to advanced cancer. The aim of this study is to analyze the effectiveness and safety of radiotherapy plus intravenous bisphosphonates versus radiotherapy alone for treating bone metastasis.

METHODSWe searched the Cochrane Library, PubMed, EMBASE, CBM, CNKI and VIP, as well as the reference lists of reports and reviews. The quality of included trials was evaluated by the Cochrane Handbook. Data were extracted and evaluated by two reviewers independently. The Cochrane Collaboration's Rev-Man 5.0 was used for data analysis.

RESULTSTwenty-two trials involving 1 585 patients were included. Compared with radiotherapy alone, radiotherapy plus intravenous bisphosphonates was more effective in total effective rate of pain relive (RR = 1.21, 95% CI: 1.13-1.30, P < 0.001), average abated time (WMD = 16.00, 95% CI: 10.12-21.88, P < 0.001), and quality of life (RR = 1.25, 95% CI: 1.08-1.45, P = 0.003, with significant differences. Side effects have no significant differences between the two groups except fever (RR = 5.61, 95% CI: 3.11-10.13, P < 0.001).

CONCLUSIONCurrent evidence supports more effective of radiotherapy plus intravenous bisphosphonates for bone metastases. The combine treatment is safe and effective.

Objective To investigate the effect of scan table on size-specific dose estimate ( size-specific dose estimate, SSDE) in children's CT scan. Methods CT imaging data and CTDIvol of 44 children ( 15 heads, 13 chests, 16 abdomen-pelvis) who underwent Siemens SOMATOM Definition AS+ 64 row 128-slice CT scan were retrospectively collected. CTDIvol of each patient was recored, WED ( water equivalent diameter) was calculated by two different methods ( with or without table) , donated as WED-T and WED-NT, then the corresponding SSDEWED ( SSDEWED-T and SSDEWED-NT ) was calculated. And the SSDEWED-NT was used as reference to evaluate the difference between WED and SSDEWED obtained by two different methods. Results Including part of table will lead to the overestimate for WED, with mean differences of 0. 10％, 2. 82％ and 2. 54％ for head, chest and abdomen-pelvis, respectively, while SSDEWED will be underestimated by 0. 06％ ( head ) , 2. 70％ ( chest ) and 1. 59％ ( abdomen-pelvis ) . Conclusions Including par of the patient table has a certain effect on SSDEWED for children, more attention should be paid for the application of SSDEWED.

Objective:To investigate the indication, effectiveness, tolerance, and safety of levosimendan in patients with acute heart failure (AHF) in 20 hospitals in Beijing, China.Methods:This prospective, observational, and multicenter study consecutively enrolled AHF patients who were treated with levosimendan at 20 hospitals in Beijing from April 2020 to March 2022. Baseline demographics, laboratory parameters, clinical presentation, concomitant diseases and medications were collected. After initiation of levosimendan, levosimendan administration, laboratory parameter pre- and post-administration, symptoms improvement, and adverse events were also collected.Results:Totally 800 AHF patients were included, 67% of whom were male, aged (65 ±17) years, 50% of whom had ischemic heart disease, and the left ventricular ejection fraction (LVEF) was (36±11)%. The dose of levosimendan was (11.84 ±2.11) mg and the mean infusion time was (1 450±307) min. Dyspnea was improved in 83.4% of AHF patients at 24 h after treatment. The level of B-type natriuretic peptide (BNP) significantly decreased from 689 (406-1509) pg/mL to 410 (156-697) pg/mL in all patients at 24-72 h after treatment ( P<0.001), and the level of N-terminal pro-brain natriuretic peptide (NT-pro BNP) decreased from 6910 (3 715-13 914) pg/mL to 2 851 (1 288-6 191) pg/mL ( P<0.001). Meanwhile, LVEF level also improved significantly [(40±11)% vs. (36±11)%, P<0.001]. During levosimendan administration, adverse events occurred in 74 (9.3%) patients, including hypotension (5.9%), arrhythmia (1.9%), and other symptoms (1.1%). Among them, 7 patients ( 2 patients with hypotension and 5 patients with ventricular tachycardia) interrupted levosimendan administration. Conclusions:The use of levosimendan is safe, and can improve symptoms reduce BNP or NT-pro BNP levels and increase LVEF level in AHF patients.

Objective:To explore the efficacy of subcutaneous injection of granulocyte-macrophage colony-stimulating factor (GM-CSF) in preventing invasive fungal disease (IFD) in patients with multiple myeloma (MM).Methods:The clinical data of 222 patients who were admitted to the Second Hospital of Harbin Medical University from January 2015 to June 2021 were retrospectively analyzed. The patients was given GM-CSF (3-5 μg·kg -1·d -1, GM-CSF group) or granulocyte colony-stimulating factor (G-CSF, 2-5 μg·kg -1·d -1, G-CSF group) when neutrophils (ANC) ≤1.5×10 9/L after induction chemotherapy. Patients were discontinued when white blood cell count (WBC) ≥10.0×10 9/L. The incidence of IFD (including confirmed, clinical and proposed diagnosis) and breakthrough invasive fungal infections was compared between the two groups. Results:The incidence of IFD was 8.1% (18/222) in all patients. The incidence of IFD was 3.5% (3/85) and 10.9% (15/137) in the GM-CSF and G-CSF groups, respectively, and the difference between the two groups was statistically significant ( χ2 = 3.88, P = 0.049). In 9 patients of GM-CSF group receiving fungal infection prophylaxis and in 15 patients of G-CSF group receiving fungal infection prophylaxis, the incidence of breakthrough invasive fungal infections was 0 and 7 cases, respectively, and the difference between the two groups was statistically significant ( P = 0.022). Conclusions:GM-CSF application in MM patients can reduce the incidence of IFD and breakthrough invasive fungal infections.
