However,gastrointestinal disease continues to account for a high proportion of presenting symptoms in these patients. Gastrointestinal symptoms in treated patients who respond to therapy are more likely to the result of drug-induced complications than OI. Endoscopic evaluation of the gastrointestinal tract remains a cornerstone of diagnosis,especially in patients with advanced immunodeficiency,who are at risk for OI. The peripheral blood CD4 lymphocyte count helps to predict the risk of an OI,with the highest risk seen in HIV-infected patients with low CD4 count (< 200 cells/mm3). This review provides an update of the role of endoscopy in diagnosing OI in the upper gastrointestinal tract in HIV-infected patients in the era of HAART.展开更多

However, the policy should not be used on regular, long-term base. Mini- stimulus economic policy is still essentially investment-driven and by nature no different from the four trillion yuan stimulus package introduced in the aftermath of the global financial crisis of 2008. The policy strength of mini-stimulus packages the Chinese government resorted to has already accumulated to ascend to quite an extent. Further, ministimulus policy cannot stabilize growth and promote economic restructuring simultaneously. In fact, its effects on restructuring are short-term and may even be negative. Additionally, the diminishing potency of China＇s mini-stimulus policy efforts may force the government to resort to another hefty stimulus package with severe side effects. In the final analysis, it is social policy not economic stimuli that will help the Chinese economy achieve a soft landing.展开更多
