[Promotion of basic research in efficacy enhancement of chronic constipation].

The incidence of chronic constipation increases year by year, but it is underestimated in affecting the health of patients. Clinical diagnosis and treatment of chronic intractable constipation is difficult, owing to the diversity of clinical manifestations and the unclear pathogenesis. The basic research is expected to identify the pathophysiological mechanism of chronic intractable constipation in the future, which can find out a ultimate solution approach and improve clinical efficacy. At present there are several basic research ways attracting our attention, including enteric nervous system (such as nerve cells, intestinal neurotransmitters, intestinal sensory nerve regulation mechanism), intestinal smooth muscle cells, Cajal interstitial cells and sacral neuromodulation and intestinal microecology. Although current basic researches are still very preliminary, but they have laid foundations of clinical drug development and application of new technology.
