It is necessary to assess the satisfaction of patients utilizing community health service（CHS） under the gatekeeper system. Our study showed that the cognition of gatekeeper policy was associated with four dimensions including doctor‐patient relationships, information and support, organization of care, and accessibility（P 〈 0.001）. One or more factors such as gender and self‐perceived health scores also affected their satisfaction. General practitioners must be prepared to focus on these aspects of information and support, organization of care, and accessibility as indicators of potential opportunities for improvement. Additionally, policymakers can improve patients＇ satisfaction with CHS by strengthening their awareness of the gatekeeper policy.展开更多

According to the sequences, six vector-derived siRNAs （denoted psiRNA1-6） and one mocking psiRNA7 were constructed. Among them, psiRNA1 and psiRNA2 targeted Rad52, psiRNA3 and psiRNA4 to Ku70, psiRNA5 and psiRNA6 to Ku80. The mocking psiRNA7 was used as control. After sequence identification, the seven plasmids were lyansfected into HepG2 cell line. siRNA-induced silencing of gatekeeper genes was determined by using RT-PCR at RNA level and Western Blot at protein level. The results showed that the six plasmids specifically targeting the coding region of gatekeeper genes were successfully designed and constructed. To some extent, the ~ pPasmids could reduce the expression of target geffe Comparatively, the plasmid-derived siRNA psiRNA1, psiRNA4 and psiRNA5 were more effective than their counterparts. The results suggest that the gene silencing etticiency of siRNA is different, depending on their targeted region, and siRNA may provide us with practical tools for further study on the three gatekeeper genes, i.e. Rad52, Ku70, Ku80.展开更多

This predictive statement is based on the consequential effect of the bankruptcy of Ertron and WorldCom and its aftermath legislature, Sarbanes-Oxley Act （Lander, 2004）. The main issues boarder on how ethics influence organizations＇ operations and to what extend these influences can be coded and managed to enhance objectivity and minimize fraud. The methodology applied in this paper was an exploratory approach under the qualitative design.

In this paper, we build a complex network with characters in Shishuoxinyu to analyze the scholarly connections in the Wei-Jin and North-South dynasties. The ER random graph, WS small-world network, BA scale-free network, and experimental network are constructed for comparison. The network properties of the experimental network were analyzed using the average degree, average clustering coefficient, and average path length. Degree centrality, mesoscopic centrality, and proximity centrality were selected to understand the importance of the experimental network nodes, and it was found that the king guide had the highest importance in the whole experimental network. Then, through the observation of network degree distribution, this experimental network is considered as a scale-free network with robustness and vulnerability, which is in line with the political characteristics of the Wei-Jin and Northern Dynasties. Finally, ten larger-scale Shi clans are selected to construct a new network for inter-clan linkage analysis. This study helps to uncover the reasons for the rise and fall of the Shi clans during the Wei-Jin and North-South dynasties.展开更多
