OBJECTIVETo determine whether lactic acid bacteria as probiotics is efficacious in the primary prevention of infantile eczema or atopic eczema.
METHODSFor this meta analysis of randomized controlled trials (RCT) describing the efficacy of probiotics in infants with eczema or atopic eczema at ages of ≤2 years, a comprehensive search in the databases was performed up to January 2010. Three reviewers independently evaluated the studies for methodological qualities. RevMan 5.0.2 software was used for meta analysis.
RESULTSTwelve RCTs on the preventive effects of lactic acid bacteria as probiotics on infantile eczema were included, and 7 of the 12 RCTs reported the preventive effect of lactic acid bacteria on atopic eczema. The meta analysis showed that there was an overall significant reduction in infantile eczema and atopic eczema favoring lactic acid bacteria compared with placebo. The relative risk (RR) ratios for eczema and atopic eczema were 0.80 (95%CI: 0.70-0.90; P<0.01) and 0.78 (95%CI: 0.64-0.97; P<0.01), respectively. Lactic acid bacteria combined with other probiotics decreased significantly the incidence of eczema, with a RR ratio of 0.79 (95%CI: 0.68-0.93; P<0.01). The use of lactic acid bacteria alone did not result in a reduction in the incidence of eczema, with a RR ratio of 0.85 (95%CI: 0.69-1.05; P>0.05).
CONCLUSIONSThe data from this meta analysis suggest that lactic acid probiotics combined with other probiotics play a role in the prevention of infantile eczema. There is insufficient evidence to recommend single use of lactic acid bacteria for prevention of eczema. Further studies are required to determine whether the findings are reproducible.

This study was aimed to investigate the effect of dendritic cells (DC) on the proliferation capability, immunophenotype changes, level of secreted cytokines and activity against leukemia of cytokine-induced killer (CIK) cells in vitro. DCs and CIK cells were induced from peripheral blood mononuclear cells of healthy volunteers. They were co-cultured meanwhile CIK cells were cultured alone as controls. Increased number of cells were counted by trypan-blue staining; the killing activity was detected by MTT assay; immunophenotype changes were analyzed by flow cytometry; the IL-12 and INF-gamma levels of the cultured supernatants were detected by ELISA kits. The results showed that the proliferation capability of DC-CIK cells was significantly higher than that of CIK cells (p < 0.05). Under the same condition, the ratio of double positive cells such as CD3(+) CD8(+), CD3(+) CD56(+) in CIK cells was significantly enhanced by co-cultured with DC cells (p < 0.05). The levels of IL-12 and INF-gamma in cultured supernatants of DC-CIK cells increased noticeably on day 3 as compared with CIK cells cultured alone (p < 0.01, p < 0.05). Within the effector-target ratio range between 5:1 to 40:1, the activity of DC-CIK cells against leukemia cells were much higher than that of CIK cells (p < 0.05), and this effect showed a positive correlation with the effector-target ratio. It is concluded that the proliferation capability of DC-CIK cells, the level of their secreted cytokines and their activity against leukemia cells are significantly higher than those of CIK cells. This research may suggest an approach for clinical immunotherapy against leukemia with DC-CIK cells.

Objective: To evaluate the clinical efficacy of sinew-regulating bone-setting manipulations plus exercise therapy in treating chronic non-specific low back pain (CNLBP). Methods: A total of 65 CNLBP patients were divided into two groups by the random number table method. Thirty-three cases in the treatment group were intervened by sinew-regulating bone-setting manipulations plus exercise therapy; 32 cases in the control group were intervened by medium-frequency electrotherapy plus exercise therapy. Before and after treatment, visual analog scale (VAS), dynamic and static muscle endurance of low back, median frequency (MF) of surface electromyography (sEMG) and Oswestry disability index (ODI) were used to evaluate the low back function. The therapeutic efficacy was estimated after treatment. Results: The two groups each had 2 dropouts during the study. The total effective rate was 90.3% in the treatment group versus 66.7% in the control group, and the between-group difference was statistically significant (P<0.05). After treatment, the VAS score, dynamic and static muscle endurance of low back, MF of sEMG and ODI score all changed significantly in both groups (all P<0.05); all the items in the treatment group were significantly different from those in the control group (all P<0.05). Conclusion: Sinew-regulating bone-setting manipulations plus exercise therapy can effectively release pain in CNLBP patients, increase muscle endurance of the low back and improve the quality of life, and its therapeutic efficacy is more significant than that of medium-frequency electrotherapy plus exercise therapy.
