Effects of mindfulness-based psychological care on mood and sleep of leukemia patients in chemotherapy

Purpose:The aim of this research was to explore the benefits of mindfulness-based psychological care(MBPC)and assess whether the intervention would be beneficial in reducing insomnia and emotional symptoms of leukemia patients receiving chemotherapy.Methods:A randomized control design study was applied in two hematology departments in a hospital in Zhengzhou.Patients in the experimental group received mindfulness-based psychological care(MBPC),and those in the control group received conventional care.Anxiety,depression,and sleeping problems were measured using the Self-Rating Anxiety Scale,Self-Rating Depression Scale,and the Pittsburgh Sleep Quality Index.Results:Statistically significant differences were observed among anxiety,depression,and sleeping problems between the two groups in the post-test(P<0.05).A significant decrease in anxiety and depression and an improvement in sleep were observed between pre-and post-interventions(P<0.05)in the experimental group.Conclusions:MBPC significantly improved sleep quality and mood of the experimental group.It is an effective complementary therapy for leukemia treatment that is inexpensive,noninvasive,and associated with relaxation and pain reduction.

Binocular vision and abnormal head posture in children when watching television

AIM： To determine the association between the binocular vision and an abnormal head posture（AHP）when watching television（TV） in children 7-14 y of age.·METHODS： Fifty normal children in the normal group and 52 children with an AHP when watching TV in the AHP group were tested for spherical equivalents, far and near fusional convergence（FC） and fusional divergence（FD） amplitudes, near point of convergence, far and near heterophoria, accommodative convergence/accommodation ratio and stereoacuity. The values of these tests were compared between the two groups. The independent t test was applied at a confidence level of95%.·RESULTS： The far and near FC amplitudes and far FD amplitudes were lower in the AHP group（the far FC amplitudes： break point 13.6±5.4~△, recovery point 8.7±5.4~△.The near FC amplitudes： break point 14.5 ±7.3~△, recovery point 10. 3 ± 5. 1~△. The far FD amplitudes ： break point3.9±2.7~△, recovery point 2.6±2.3~△） compared with those in the normal group（the far FC amplitudes： break point19.1 ±6.2△, recovery point 12.4 ±4.5~△. The near FC amplitudes： break point 22.3 ±8.0~△, recovery point 16.1 ±5.7~△. The far FD amplitudes： break point 7.0 ±2.1~△,recovery point 4.6 ±1.9~△）. Other tests presented no statistically significant differences.·CONCLUSION： An association between the reduced FC and FD amplitudes and the AHP in children when watching TV is proposed in the study. This kind of AHP is considered to be an anomalous manifestation which appears in a part of puerile patients of fusional vergence dysfunction.

Influence of extract of Ginkgo biloba leaves tablets on the aquaporin-1 expression in isolated lung ischemia reperfusion

Background The extract of Ginkgo biloba leaves tablets, ginaton, is widely used in treating ischemic cerebrovascular disease in the clinic. This study aimed to investigate the expression of aquaporin-1 （AQP-1） in rat lung with ischemia/ reperfusion injury after pretreatment with ginaton, and whether the pretreatment with ginaton reduces the acute lung injury caused by ischemia/reperfusion injury. Methods Adult Wistar rats were divided into two groups. Some rats were used as donors （n=20）, the others as recipients （n=20）. Left lungs of donor rats were used for the isolated lung reperfusion model, which perfused only with low potassium dextran （LPD） solution as group A （n=10）; the others were pretreated with ginaton before reperfusion as group C （n=10）. Right lung of donor rat without any treatment was used as a control group （group B and group D, n=10 for each group）. After the model was established, the expression of AQP-1 in the lung tissues was examined by immunohistochemistry, Western blotting, and reverse transcriptase-polymerase chain reaction. Results Immunohistochemical examination revealed that AQP-1 was expressed in endothelia. Immunoblotting demonstrated that the relative gray values of AQP-1 protein in groups A and C were 0.65±0.06, 0.88±0.11, respectively. The relative gray values of the mRNA expression in groups A and C were 0.30±0.08, 0.49±0.11, respectively. The expression of AQP-1 protein and mRNA in group C was significantly higher than in group A （P 〈0.05）. Conclusion The pretreatment with ginaton can reduce the acute lung injury caused by ischemia/reperfusion.
