Objective: To observe syndrome types of Chinese medicine (CM) and distribution features of acute infectious diarrhea patients.
Methods: A retrospective study was performed in 465 acute infectious diarrhea patients. The distribution of CM syndrome and syndrome types in different seasons and genders were analyzed.
Results: Lack of appetite [381 (81.94%)], fatigue [350 (75.27%)], abdominal pain [338 (72.69%)], tenesmus [325 (69.89%)], anal scorching hot [276 (59.35%)], nausea [25 (55.48%)], diarrhea [249 (53.55%)], short yellow-urine [240 (51.61%)], thirsty [210 (45.16%)], and abdominal distention [206 (44.30%)] were most often seen. The syndrome distribution were sequenced as intestinal damp heat syndrome [268 (57.63%)], dyspeptic retention in intestine and stomach syndrome [106 (22.80%)], cold-damp invading exterior syndrome [47 (10.11%)], Pi-Wei qi deficiency syndrome [23 (4.95%)], cold-damp disturbing Pi syndrome [21 (4.52%)]. The incidence ratio of intestinal damp heat syndrome was the highest in autumn (P < 0.01), while that of cold-damp invading exterior syndrome was the highest in winter (P < 0.01). Cold-damp disturbing Pi syndrome was more often seen in females than in males (P < 0.01), and its incidence ratio was the highest in autumn (P < 0.05). The incidence ratio of dyspeptic retention in intestine and stomach syndrome was the highest in winter (P < 0.01).
Conclusions: Intestinal damp heat syndrome was the most often seen in acute infectious diarrhea. Incidence ratios of in- testinal damp heat syndrome and cold-damp disturbing Pi syndrome were higher in autumn, while those of cold-damp invading exterior syndrome and dyspeptic retention in intestine and stomach syndrome were higher in winter. Cold-damp disturbing Pi syndrome was more often seen in females.
