Objective To evaluate acute and long2term angiographic and clinical outcomes of longstent or multiple overlapped stents (length ≥ 20 mm) implantation for diffuse atherosclerosis lesions inoctogenarians. Methods Long stent or multiple overlapped stents implantation was performed on 111diffuse native coronary lesions ( Group O : 47 lesions in 44 octogenarians ; Group Y: 64 lesions in 58 patientsaged under 60) . Baseline demographic , lesion characteristic , angiographic and procedural details weresimilar in these 2 groups. Six2month clinical and angiographic follow2up was completed in all cases. In2hospital and long2term outcomes were evaluated. Results Procedure success was 100 %for both had in2hospital major adverse cardiac events (MACE) . There was no significant difference inangiographic binary restenosis ( ≥50 % diameter stenosis) rate between the groups at follow2up ( Group Ovs. Group Y, 1218 % vs1 1019 % at 32month , 2918 % vs. 2616 % at 62month , P > 0105) . The rates oftarget lesion revascularization and MACE at follow2up were less in Group Y, but it showed no statisticalsignificance (718 % vs. 1016 % and 816 % vs. 1114 % at 32month , 1516 % vs. 2314 % and 2017 % % at 62month , respectively , P > 0105) . Conclusions Long stent implantation for diffuse lesionsin octogenarians appears safe and feasible , with high procedural success and favorable long2term outcomes.

Sample 2 Natural Gas Output in China With the rapid economic growth in China, there has been an increasing demand for fuel resources. Among them, natural gas is clean, convenient and inexpensive. The above graph shows the output of natural gas in China beeen 1991 and 1995. As can be seen from the graph, there had been a steady increase in its output since 1991. In 1991, there was only billion cubic meters of natural gas produced in China. After that, almost every year witnessed a steady increase by billion cubic meters. By 1995, the output had increased to billion cubic meters, an increase by about 13% over that of 1991. There are many factors leading to this sharp increase in its output. To name only a few, the greater industrial demand, demands from daily life, convenience and cleanness in itself, etc. stimulate its output increase. In conclusion, we can safely predict the output will continue to increase in the foreseeable future because of the greater demands for it.

New car problem Nowadays more and more families own their private people would find it hard to think what life could look like without a cars have led us to a better life,they have also brought us many new problems.
