Translate the following passage into Chinese

Since the end of the 80s and beginning of the 90s, many blood banks have been set up in the eastern and southern regions of Henan Province and, as a result, a large number of peasants have rushed to sell their blood. Some families and villages have become regular sellers of blood, and their numbers have sometimes then expanded to encompass a whole township. This situation has sometimes then also spread to neighbouring counties. As a result, blood selling has become a local ‘industry’.

In the 80s various pharmaceutical companies went to isolated and poor regions of Henan Province to buy cheap blood to make drugs, and following the encouragement of some local governments many poor peasants rushed to sell their blood. In order to save trouble and expense, the blood dealers used one-use-only needles many times.
