Objective To evaluate the efficiency and safety of exercise interventions on cancer related fatigue. Methods Cochrane Library, JBI Database of Systematic Reviews, MEDLINE, EMbase, CINAHL, Chinese Journal Full- text Database, Chinese Biomedical Literature Database, and Wanfang Databse were searched from the inception to November 2014 to screen the systematic review and Meta-analysis conforming to the inclusion criteria. Two authors independently appraised their methodological qualities with Overview Quality Assessment Questionnaire (OQAQ), and analyzed the data using descriptive analysis. The primary outcome included the scaling of cancer related fatigue, the secondary outcome included adherence to exercise intervention and the incidence of adverse events. Results Fourteen systematic review/Meta-analysis were identified, twelve of them had a high methodological quality (Scoring 5-7). Six systematic review/Meta-analysis found that aerobic exercise could effectively alleviate cancer related fatigue, especially for breast cancer patients;seven articles showed that exercise could modulate cancer related fatigue of patients under active treatments;seven articles reported the compliance to the exercise intervention, four articles reported adverse events occurring during the intervention, very few of them resulted directly from the exercise intervention. Conclusions Exercise intervention can modulate cancer related fatigue with good safety.

For investigating the effect of Jumonji domain-containing protein-3 (JMJD3) on the behavior of lung cancer cell line, A549 proliferation was measured with EDU staining and flow cytometer after JMJD3 expression plasmid and pcDNA3. 1 transfection at 48h. The migration ability of A549 was tested at the same time. The expression of p21 mRNA was measured with RT-PCR. The results showed that JMJD3 transfection increased the EDU positive cells ratio (JMJD3: 40.75% +/- 2.07%, control: 20.97% +/- 1.5%, P < 0.001). G1 phase cell ration also increased after JMJD3 transfection (JMJD3:47. 80% +/- 1.85%, control: 54.60% +/- 0.95%, P = 0.005). The mRNA expression of p21 decreased in JMJD3 group (JMJD3: 35. 89% +/- 3.71%, control: 91.78% +/- 3.74%, P < 0.001). The distances of migration were (0.47 +/- 0.27) cm and (0.96 +/- 0.40) cm after 24h and 48h with JMJD3 tranfection, compared to (0.57 +/- 0.22)cm and (1.08 +/- 0.33)cm in control, respectively (P > 0.05). JMJD3 promoted the proliferation of A549 and decreased the G1 cell numbers, decreased the p21 mRNA, but had no effect on A549 migration.

OBJECTIVE: To investigate the relationship between apoptosis of myocardial cells in spontaneously hypertensive rats (SHRs) and the expressions of Bcl-2 and Bax protein, and the protective effect of stellate ganglion block on apoptosis of myocardial cells. METHODS: A total of 32 ten-week-old male SHRs were assigned randomly into 4 groups: a left stellate ganglion block group (group LS), a right stellate ganglion block group (group RS), a captopril group (group D) and a control group (group C). The arterial systolic blood pressure was measured by ALC-NIBP system. After 10 weeks, all rats were anaesthetized by 3% pentobarbital sodium, cardiomyocyte apoptosis index of left ventricle was assessed by TUNEL, and the localization of myocardium Bcl-2, Bax was investigated by immunohistochemistry. RESULTS: Compared with group LS and C, the apoptotic index decreased (P<0.05). SHR myocardial expression of Bcl-2 significantly increased (P<0.05), Bax expression significantly decreased (P<0.05) and Bcl-2/Bax was significantly higher (P<0. 05) in group RS. CONCLUSION Bcl-2 and Bax play an important role in the apoptosis of myocardial cells in SHRs. Right stellate ganglion block can reduce the apoptosis of myocardial cells and reverse the reconstruction of the left ventricle in SHRs via regulation of apoptosis-related gene proteins.
