Influence of mindfulness group training on procrastination, self esteem, self efficacy of middle school students / 中国学校卫生

Objective@#To explore the influence of mindfulness group training on the procrastination, self esteem and self efficacy of middle school students, so as to provide a reference for mental health promotion of middle school students.@*Methods@#A total of 120 cases of middle school students selected by the stratified random sampling were randomly divided into observation group and control group, with 60 cases in each group. The control group did not accept any intervention,the observation group accepted mindfulness group training. The Five factors of Mindfulness Questionnaire (FFMQ), Chinese Irrational Procrastination Scale (IPS) and Active Procrastination Scale (APS), Rosenberg Self esteem Scale (RSES), General Self efficacy Scale (GSES) were measured before and after training.@*Results@#After training, the FFMQ score in the observation group was (122.87±18.48), significantly lower than (106.55±15.36) the control group( t=5.26, P <0.05); the rate of low mindfulness in the observation group was significantly lower than the control group(8.33%, 33.33%, χ 2=11.37, P <0.05). The scores of IPS and APS in the observation group were ( 17.89 ±4.21) and (40.94±9.25), significantly lower than (28.67±5.43) and (55.64±10.82) the control group( t= -12.15 , -8.00, P <0.05); the rate of high procrastination behavior of IPS and APS in the observation group was 20.00% and 23.33% , significantly lower than 38.33% and 41.67% the control group( χ 2=4.88, 4.60, P <0.05). The scores of GSES and RSES scores in the observation group were (34.17±3.42) and (34.71±4.64), significantly higher than (30.09±3.35) and (30.23±4.23) the control group( t=6.60, 5.53, P <0.05); the rate of low self efficacy and low self esteem in the observation group was 15.00% and 18.33%, significantly lower than 33.33% and 36.67% the control group( χ 2=5.50, 5.06, P <0.05).@*Conclusion@#Mindfulness group training is conducive to improving the level of mindfulness of middle school students,reducing the procrastination behavior, improving the self esteem and self efficacy, which can improve adolescents physical and mental health.

Up-regulation of peroxiredoxin 3 by high-risk human papillomavirus in cervical cancer cells / 中华实验和临床病毒学杂志

Objective@#The present study was conducted to investigate the response of peroxiredoxin 3 (PRX3) to oxidative stress induced by high-risk human papillomavirus (HPV).@*Methods@#Sixty patients with cervical cancer were included and sixty patients with hysteromyoma were assigned as controls. Serum PRX3 was detected by enzyme-linked immunosorbent assay. The expression of PRX3 and oncoprotein E6 of HPV16 or HPV18 was examined in cervical cancer tissues by immunohistochemistry and in cervical cancer cells by Western blotting respectively.@*Results@#Patients with invasive squamous cervical cancer showed higher level of serum PRX3 than control subjects with hysteromyoma. PRX3 expression was up-regulated and was positively associated with that of E6 of HPV16 or HPV18 in cervical cancer tissues. The correlation was confirmed in HPV-containing cervical cancer cell lines including CaSki, and HeLa.@*Conclusions@#Our result indicated a positive response of PRX3 to HPV-induced oxidative stress. Serum PRX3 might be a potential indicator of active amplification of high-risk HPV in cervical cancer cells.

Advances in therapeutic options of peripheral T-cell lymphoma / 中国肿瘤临床

To date, the treatment of peripheral T-cell lymphomas (PTCL) has lagged behind B-cell malignancies. Traditionally, para-digms for diffuse large B-cell lymphoma were applied to patients with PTCL, but the outcomes were poor. Recently, the FDA has ap-proved four drugs for patients with relapsed/refractory PTCL, and the Japanese government has approved of anti-CCR4 monoclonal an-tibody for patients with adult T-cell leukemia/lymphoma. Clinical studies are exploring the combination of these new agents into stan-dard CHOP-based regimens for patients with newly diagnosed PTCL. Recent studies have revealed that PTCL may be associated with epigenetic dysregulation and is thus sensitive to histone deacetylase inhibitors. These advances provide a new understanding of PTCL, whose therapeutic options will be presented in this review.

Efficacy of bendamustine hydrochloride in patients with rituximab-refractory indolent B-cell non-Hodgkin's lymphoma：results from a phaseⅢmulticenter study / 中国肿瘤临床

Objective:To evaluate the efficacy and toxicity of single-agent bendamustine in patients with indolent B-cell non-Hodgkin's lymphoma (NHL) refractory to rituximab. Methods:Between April 2010 and April 2013, 100 patients with rituximab-refrac-tory indolent B-cell NHL from 8 institutions were enrolled. Bendamustine was administered at 120 mg/m2 on days 1 and 2 every 21 days for 6-8 cycles. The primary endpoint was the overall response rate (ORR). The secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results:One hundred patients with a median age of 56 (rang-ing from 28 to 74) years were recruited in this clinical study. The total number of chemotherapy was 447 cycles, and the median number was 4 cycles. Ninety-three patients could be evaluated for efficacy. Fifteen patients (16.1%) had complete remission (CR), 52 (55.9%) had partial remission (PR), 22 (23.7%) had stable disease (SD), and 4 (4.3%) had progression disease (PD). The ORR and DCR were 72%and 95.7%, respectively. After a median follow-up of 26.6 months (ranging from 2 to 48.4 months), 59 patients (63.4%) had PD.The median PFS was 8.53 (95%CI:6.518-10.542) months, and PFS rate for 1 year was (40.6±5.3)%. Forty-eight patients (48%) had 3/4 grade adverse events, including leucopenia (26%), neutropenia (24%), and anemia (11%). Conclusion:Single-agent bendamustine produced a high rate of objective responses in patients with rituximab-refractory indolent B-cell NHL and could be one of the new op-tions for second-line treatment of these patients. The most common adverse event is hematologic toxicity.
