OBJECTIVE: To analyze treatment effectiveness in terms of the medication injection site. METHODS: The medical records of 423 patients with cerebral palsy who were admitted to Maternal and Child Health Hospital between January 2009 and December 2016 were collected. All cases were divided into T1, T2, T3, and T4 groups based on the use of conventional medication sites and acupoints for administering injectable medicines. RESULTS: In the T1 group, patients received injections at conventional medication sites between 2009 and 2010. In the T2 group, patients received injections at conventional medication sites combined with acupoint injection therapy I from 2011 to 2012. In the T3 group, injection at conventional medication sites plus acupoint injection II was applied between 2013 and 2014. Acupoint injection only was used in the T4 group from 2015 to 2016. Therapeutic effects were statistically compared among the different injection procedures. The overall Gross Motor Function Measure (GMFM) and Fine Motor Function Measure (FMFM) scores were significantly improved after hospital discharge. The GMFM score was considerably higher in the T4 group than in the other groups (all P = 0.001 < 0.05). The GMFM scores were significantly higher in the T2 groups than in the T1 group (P = 0.001< 0.05), but no significant difference was observed between the other paired comparions (P > 0.05). Meanwhile, the FMFM scores were significantly higher in the T2 and T4 groups than in the T1 and T3 groups (all P = 0.001 < 0.05). Site injection therapy can significantly improve gross and fine motor function in children with cerebral palsy. CONCLUSION: It is feasible to administer injectable medicines at acupoints instead of convention sites to enhance the therapeutic effect of treatment in patients with cerebral palsy. 展开更多

BACKGROUND It is evident that current clinical criteria are suboptimal to accurately estimate patient prognosis.Studies have identified epigenetic aberrant changes as novel prognostic factors for colorectal cancer(CRC).AIM To estimate whether a methylation gene panel in different clinical stages can reflect a different prognosis.METHODS We enrolled 120 CRC patients from Tri-Service General Hospital in Taiwan and used the candidate gene approach to select six genes involved in carcinogenesis pathways.Patients were divided into two groups based on the methylation status of the six evaluated genes,namely,the<3 aberrancy group and≥3 aberrancy group.Various tumor stages were divided into two subgroups(local and advanced stages)on the basis of the pathological type of the following tissues:Tumor and adjacent normal tissues(matched normal).We assessed DNA methylation in tumors and adjacent normal tissues from CRC patients and analyzed the association between DNA methylation with different cancer stages and the prognostic outcome including time to progression(TTP)and overall survival.RESULTS We observed a significantly increasing trend of hazard ratio as the number of hypermethylated genes increased both in normal tissue and tumor tissue.The 5-year TTP survival curves showed a significant difference between the≥3 aberrancy group and the<3 aberrancy group.Compared with the<3 aberrancy group,a significantly shorter TTP was observed in the≥3 aberrancy group.We further analyzed the interaction between CRC prognosis and different cancer stages(local and advanced)according to the methylation status of the selected genes in both types of tissues.There was a significantly shorter 5-year TTP for tumors at advanced stages with the promoter methylation status of selected genes than for those with local stages.We found an interaction between cancer stages and the promoter methylation status of selected genes in both types of tissues.CONCLUSION Our data provide a significant association between the methylation markers in normal tissues with advanced stage and prognosis of CRC.We recommend using these novel markers to assist in clinical decision-making. 展开更多

Plastic film mulch in agricultural production becomes essential to maintaining crop yields in arid and semiarid areas.However,the presence of residual film in farmland soil has also drawn much attention.In this study,three experiments were conducted.The first two experimental designs included 0,450,1350,and 2700 kg ha^(-1) of residual film pieces of approximately 5 cm side length added to field soil(0-20 cm soil depth)for seven years and added to pots for four years.In the third experiment,1350 kg ha^(-1)of the residual film with different side lengths(2-5,5-10,10-15,and 15-20 cm)was added to field soil for six years to explore the effect of residual film fragment size on soil nutrients,soil microorganisms,crop growth and yields.The residual film had little effect on the soil moisture at a field depth of 0-2(or 0-1.8)m.There were no significant effects on organic carbon,total nitrogen,inorganic nitrogen,total phosphorus or available phosphorus in the 0-20 cm soil layer.The presence of residual film decreased the richness and diversity of the bacterial community of the surface soil of the residual film,but it had no significant effect on the microbial community of the non-surface soil.The emergence rates of wheat and lentils occasionally decreased significantly with different amounts of residue fragments added to the field.At 450-2700 kg ha^(-1),the residual film reduced the plant height and stem diameter of maize and significantly reduced the shoot biomass of harvested maize by 11-19%.The average yields of maize and potato over the seven years decreased,but there were almost no significant statistical differences among the treatments.These results provide important data for a comprehensive scientific understanding of the effects of residual film on soil and crops in dryland farming systems. 展开更多

Considering different contact situations of grains, we effective anisotropies of magnetically soft α-Fe grains, investigate the effects of exchange-coupling interaction on hard Nd2Fe14B grains and NdaFe14B/α-Fe nanocomposite. An expression of effective anisotropy suitable for different degrees of exchange-coupling between grains is presented. The calculation results show that the exchange-coupling interaction increases the average anisotropy of soft grains and decreases that of hard grains. The effective anisotropy of Nd2Fe14B/α-Fe nanocomposite decreases smoothly with decreasing grain size when the grain size is larger than 20 nm while it decreases dramaticaily with further decrease of the grain size. In order to maintain high coercivity in Nd2Fe14B/α-Fe nanoeomposite, the grain size should not be less than 20nm. 展开更多
