资料：The business announced that revenues had grown by 10.2 percent year-on-year to RMB 18.264 billion （$2.748billion）. However, profit fell to RMB 2.866 billion （$431.3 billion）, a 17.4 percent decrease from the same period in 2015.
Robbin li, Chairman and CEO of Baidu, said:"The challenges Baidu faced in the second quarter served as a healthy reminder to stay focused on the key drivers of growth, sustainability and leadership; delivering the best user experience and staying at the forefront of technology. As we enter the next chapter of the Internet, led by artificial intelligence, Baidu has never been better positioned to serve our users and work with our customers and partners, and change the world through technology." The business has been rocked by a series of high profits issues with its advertising business this year. Baidu was called out for its practices around selling access to forums early this year. Not long after it also agreed to overhaul the way it delivers its search ads, including the volume of ads served, after a huge public backlash saw Baidu taking some of the blame for the death of a student who died after taking experimental cancer treatment that be found from a search ad.
The overhaul has been welcomed by the industry which believes will create a better experience, particularly on mobile.
The business said the revenue from mobile was growing as it represented 63 percent of total revenues for the second quarter of 2016, compared to 50 percent in 2015. According to Baidu, mobile search monthly active users were 667 million for the month of June 2016, an increase of 6 per cent year-over-year. It said users of its mobile maps service grew by 13 percent and the number of activated Baidu Wallet accounts reached 80 million, representing a 131 percent year-on-year growth.
According to the last paragraph, what action will Baidu possibly take?

Most Adults in US Have Low Risk of Heart Disease
More than 80 percent of US adults have a less than 10-percent risk of developing heart disease in the next 10 years,according to a report in the Journal of the American College of Cardiology.Just 3 percent have a risk that exceeds 20 percent.
"I hope that these numbers will give physicians,researchers,health policy analysts,and others a better idea of how coronary heart disease is distributed in the US population,"lead author Dr.Earl S.Ford,from the Centers for Disease Control and Prevention in Atlanta,said in a statement.
The findings are based on analysis of data from 13,769 subjects,between 20 and 79 years of age,who narticipated in the Third National Health and Nutrition Examination Survey from 1988 to 1994.
Overall,82 percent of adults had a risk of less than 10 percent,15 percent had a risk that fell between 10 to 20 percent,and 3 percent had a risk above 20 percent.
The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group.By contrast,race or ethnicity had little effect on risk distributions.
Although the report suggests that most adults have a low 10-year risk of heart disease,a large proportion have ahigh or immediate risk,Dr.Daniel S.Berman,from Cedars-Sinai Medical Center in Los Angeles,and Dr.Nathan D.Wong,from the University of California at Irvine,note in a related editorial.
Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward,they add.
