Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Prone position ventilation(PPV)is a lung protective ventilation strategy widely used in patients with acute respiratory distress syndrome(ARDS)to improve ventilation and oxygenation of the lungs by changing the patient's position.During PPV treatment,patients may face a variety of complications and risks,such as pressure injury,brachial plexus injury,corneal injury and unplanned extubation,which aggravate the patient's pain,increase medical costs and affect the prognosis of the disease.To this end,medical staff at Zhongda Hospital Southeast University jointly designed a PPV patient care kit pillow and obtained a National Utility Model Patent of China(patent number:ZL 202221128961.7).The PPV patient care kit pillow is composed of head pad,chest pad,hip pad and lower limb pad,with gel on its surface,which can reduce friction force and shear force;grooves are set on the middle of head pad,two sides above chest pad,middle of chest pad,middle of hip pad and lower limb pad,which can effectively avoid compression of corresponding parts and reduce the risk of pressure injury;and air bags are set on both sides below head pad,hip pad and lower limb pad,which can be inflated unilaterally or bilaterally at the same time and used for deflecting or elevating the body;in addition,a tube limiting groove is set on the outside of head pad,which can effectively fix the tracheal tube and reduce the risk of tube displacement and unplanned extubation.The overall structure of the pillow of this PPV patient care kit conforms to the angle of human mechanics and has strong versatility,which can improve the comfort,safety and effectiveness of PPV therapy for patients and reduce the work burden of medical staff,and has good application value.

Recently, accumulating evidence suggests that high bilirubin level is involved in the pathophysiology of schizophrenia. High bilirubin level during early childhood may increase the risk of being suffered from schizophrenia after adulthood, and schizophrenia patients with high bilirubin level have aggravated psychiatric symptoms. As compared with other psychiatric patients and general population, schizophrenia patients usually have relatively higher bilirubin level; high bilirubin level is associated with acute psychotic states, positive symptoms, and poor prognosis in patients with schizophrenia. This article reviews the relation between bilirubin and schizophrenia and its potential pathophysiological mechanism in order to provide a new direction for the study of schizophrenia pathogenesis and auxiliary diagnosis.

Objective To summarize the key points of nursing care in reservation of catheters in 11 cases of nasopharyngeal carcinoma patients who received concurrent chemo-radiotherapy with symptomatic thrombosis after ultrasound-guided implantation of double-lumen PICCs(PowerPICC).Methods From January,2014 to December,2015,totally 11 cases with symptomatic venous thromboembolism were identified among 109 cases of nasopharyngeal carcinoma patients receiving concurrent radiotherapy and chemotherapy,and observation and nursing care were provided at the early stage of thrombosis and during thrombosis.Results All double-lumen PICCs were reserved,and no recurrence or aggravation of thrombosis was recorded to the end of the treatment.The duration of carrying PICCs was 67～89(77.45±6.65) days.Conclusion With careful treatment and nursing,PICC catheter-related complications can be reduced and the duration of carrying catheters can be prolonged,which leads to accomplishment of the treatment plan for patients.

Objective: To explore the mechanism of abnormal expression of microRNA155 (miR155) in myeloma drug-resistance to probe the possibility of inhibiting miR155 expression to restore chemotherapy sensitivity and its molecular mechanism in drug-resistant myeloma cells. Methods: Drug-resistant myeloma cell-line RPMI8226/DOX was established by culturing RPMI8226 cells with continuous low concentration and intermittent gradually increasing concentration of doxorubicin in vitro; The levels of miR155 mRNA were measured by qRT-PCR, and both proteins FOXO3a and BCL-2 expressions were detected by Western blot in cell-lines RPMI8226/S and RPMI8226/Dox. RPMI8226/DOX cells were transfected by miR155 inhibitor and mimic using gene transfer method, and then CCK-8 was used to measure proliferation and inhibition ratio, the changes of miR155 expression were detected by RT-PCR. Proteins FOXO3a and BCL-2 were detected by Western blot. Results: Comparing with RPMI8226 cells, the level of miR155 mRNA was obviously up-regulated with the relative expression of 26.860±2.340, together with increased expression of Bcl-2 protein but decreased expression of FOXO3a in RPMI8226/DOX cells. After 72 h treatment with miR155 inhibitor, the inhibition rate of transfection was 64.57%, miR155 expression decreased sharply, the level of FOXO3a expression was upregulated while BCL-2 expression decreased, chemotherapy sensitivity was restored on cell-line RPMI8226/DOX with reversed drug-resistance ratio of 2.518. Conclusions The abnormal expression of miR155 was closely associated with myeloma drug-resistance, targeting inhibition of miR155 expression could restore chemotherapy sensitivity by increasing FOXO3a expression in drug-resistant myeloma cells.
