1. Puerarin protects human bronchial epithelial cells from apoptosis induced by gunpowder smog
Medical Journal of Chinese People's Liberation Army 2016;41(1):72-77
Objective To investigate protective effects of puerarin on the human bronchial epithelial (BEAS-2B) cell line against apoptosis caused by gunpowder smog and its mechanisms. Methods BEAS-2B cells cultured in vitro were randomly divided into control group, smog group (the group treated with 4g gunpowder smog for lOmin), and smog + puerarin group [puerarin groupj the cells were pre-incubated with various concentrations of puerarin (12.5, 25.0, 50.0, 100.0µg/ml) and then exposed to smoke]. Puerarin was added into the cells after innoculation for 12h and then the cells were sequentially cultured for 24h and followed by exposure to smoke for lOmin. After being cultured again for 2h, the smoked cells were examined for cell viability using Cell Counting Kit-8(CCK-8); cell apoptosis was observed using Hoechst33258 nucleus staining, and positive rates of Annexin V-PI staining cells and caspase-3 were determined with flow cytometer. Results Compared with control, treatment of BEAS-2B cells with 4g gunpowder smog induced a characteristic ap op to tic cell death (P<0.01). Pretreatment with various concentrations of puerarin antagonized the action of gunpowder smog in different degrees. The 25µg/ml was determined as the optimal effective concentration of puerarin. Compared with smog group, the apoptosis rate of BEAS-2B cells and positive rates of Annexin V-PI staining cells and caspase-3 were decreased significantly in smog + puerarin group (P<0.05, P<0.01). Conclusion Gunpowder smog can induce apoptosis of BEAS-2B cells in vitro, while pretreatment with puerarin could protect BEAS-2B cells against apoptosis induced by gunpowder smog.

Objective: To systematically review the efficacy and safety of arsenic trioxide (ATO) in treatment of acute promyelocytic leukemia (APL). Methods: The Cochrane Library (Issue 1, 2009), Cochrane Central Register of Controlled Trials (from 1970 to January 2009), MEDLINE (from 1978 to October 2008), EMBASE (from 1950 to March 2009), Chinese Biological Medical Literature Database (from 1978 to December 2008), China National Knowledge Infrastructure (CNKI, from 1994 to December 2008), and China Medical Academic Conference Database (from 1994 to December 2008) were electronically searched. We also searched the Meta-Register of controlled trials, Conference Proceedings of American Society of Hematology (from 1946 to December 2008) and Conference Proceedings of American Society of Clinical Oncology (from 1946 to December 2008) on the internet for grey literature. The related journals in the library of Third Military Medical University were hand-searched. The randomized controlled trials (RCTs) of ATO in treatment of APL were included. We adopted complete remission, overall survival rate, disease free survival rate, time to complete remission, relapse rate, mortality and adverse reactions as outcome indicators. Data were entered and analyzed with the Cochrane review manager software 5.0 (RevMan 5.0). Results: After merger of the included trials, five eligible RCTs with 328 cases were included. All the RCTs focused on the comparison of all-trans retinoic acid (ATRA) plus ATO regimen with ATRA monotherapy. Meta-analysis showed that the effect indexes for time to complete remission, two-year disease free survival rate, relapse rate, incidence of edema and incidence rate of QT interval prolongation were -1.20 [-1.68, -0.72], 8.64 [1.66,45.00], 0.21 [0.09,0.47], 4.16 [1.46,11.79] and 22.10 [2.75,177.49], respectively. The influences on other outcome indicators such as complete remission and leukocytosis were statistically non-significant. Conclusion: ATO can prolong disease free survival and reduce the time to complete remission and relapse rate of newly diagnosed APL patients, and increase the incidence of edema and prolongation of corrected QT interval during the treatment. Due to limitation of the included trials, this conclusion needs to be validated by further studies.

Objective To compare the efficacy and safety of arsenic trioxide ( ATO) with all-trans retinoic acid ( ATRA) for the treatment of acute promyelocytic leukemia ( APL) . Methods We searched the database of Cochrane Library ( Issue 1,2009) ,CENTRAL ( 1970 to 2009) ,Medline ( 1978 to 2008) ,EMBASE ( 1950 to 2009) ,CBM ( 1978 to 2008) ,CNKI ( 1994 to 2008) and CMAC ( 1994 to 2008) . We also searched the Meta register,Conference Proceedings of American Society of Hematology ( 1946 to 2008) and American Society of Clinical Oncology ( 2004 to 2008) on the internet for grey literature. We had searched the related journals in the library of Third Military Medical University,too. We included randomized controlled trials which compared ATO with ATRA for the treatment of APL. We adopt complete remission rate,overall survival rate, disease-free survival rate,time to complete remission,relapse rate,mortality and adverse reactions as result indicators. Data were entered and analyzed with the Cochrane review manager software ( Revman 5. 0) . Results Four eligible randomized controlled trials ( RCTs) were included ( n =243) . All the RCTs were methodologically graded as B. They all are focusing on the comparison of ATO monotherapy with ATRA monotherapy in treating newly diagnosed APL patients. Meta analysis showed that effect index for complete remission,2-year disease-free survival,time to complete remission,relapse rate and mortality was 0. 96 ( 0. 50,1. 86) ,2. 76 ( 0.71,10.66) ,-1.30 d ( -1.83,-0.78) ,0.86 ( 0.45,1.63) ,and 1.15 ( 0.45,2.95) ,respectively. All indicated no statistically significant difference. Effect index for incidence of liver dysfunction was 3. 03 ( 1. 25, 7. 37) ,which showed statistically significant difference between ATO group and ATRA group. Conclusion ATO is not superior to ATRA in treating newly diagnosed APL patients regarding complete remission,diseasefree survival rate,time to complete remission,relapse rate and mortality. What is worse,it will increase the incidence of liver dysfunction during treatment. Due to limitation of included trials,this conclusion need to be validated by further studies.

Objective To investigate the influence of a multifaceted stroke telehome-care (THC) on extremities function, activities of daily living (ADL) and quality of life in stroke patients with hemiplegia. Methods A total of 52 stroke survivors in department of neurology were randomized to the THC intervention or usual care. The patients in the control group received conventional care, while those in the intervention group were additionally given a THC program over 3 months. The THC intervention includes motor imagery and adaptive strategies. Data collection was undertaken using the Fugl-Meyer Motor Assessment Scale (FMA), the Barthel Index (BI), the Stroke Impact Scale (SIS) at baseline, 3 months, and 6 months. Results At baseline, the scores of FMA, BI, and SIS in the intervention group were 53.62 ± 23.52, 54.04 ± 17.44, 179.96 ± 28.51, and while the scores of the control group were 50.96 ± 19.52, 49.46 ± 15.09, 169.23 ± 28.48. There were no pre-existing differences on any scale between the two groups (t=0.443, 1.012, 1.358, P > 0.05). At 3 months, the scores of FMA, BI, SIS in the control group were 53.54 ± 17.45, 50.77 ± 14.47, 76.19 ± 27.78, and were significantly lower than 78.38 ± 12.54, 74.62 ± 11.22, 228.54±22.63 in the THC group (t=5.895, 6.641, 7.449,P<0.01). At 6 months, the scores of FMA, BI, SIS in the control group were 57.88±17.89, 59.08±13.85, 183.92±26.56, and were significantly lower than 90.58 ± 9.60, 86.54 ± 9.88, 252.19 ± 20.10 in the THC group (t=8.211, 8.233, 10.451, P < 0.01). Conclusions A telehome-care program that provide distance training and education of disabled persons resulted in greater improvements in physical functioning, ADL and quality of life.
