| Objective: To investigate the clinical characteristics and differentiation of TCM syndromes of mild and moderate pediatric virus myocarditis, and to explore effevtive TCM regulations of diagnosis and therapy.Methods: (1)Grade the commonly encountered symptoms and physical signs of mild and moderate pediatric virus myocarditis. (2)Fill out "pediatric virus myocarditis TCM syndromes questionnaire" in detailed, and classify the cases according to different TCM syndromes. (3)Analyze the relationship between age, course and TCM syndromes with statistical method, and study the distributing state of TCM symptoms and physical signs. (4)Elect TCM symptoms and physical signs having more groups with statistical significance in multiple comparison, namely TCM symptoms and physical signs having better discrimination, and make out discriminant function of TCM syndromes. (5)On the basis of TCM syndromes investigation, establish effevtive TCM regulations of pediatric virus myocarditis.Results:1. The chief symptoms of mild and moderate pediatric virus myocarditis are hypodynamia (53.8%), chest distress (48.4%), palpitation (29.0%), dizziness (24.2%), cacochroia (24.2%), pectoralgia (22.0%), Jie Dai Mai (13.4%), sweat (10.2%), cardiac dilatation (5.9%), cold limbs (1.1%); the secondary symptoms are red throat (75.8%), abnormal tongue (72.6%), fever (25.8%), abnormal stool (23.1%), cough (22.6%), nausea (9.7%), myalgia (8.1%).2. The commonly encountered TCM syndromes of mild and moderate pediatric virus myocarditis are Feng Re Fan Xin (60.2%), Qi Yin Liang Xu (18.8%), Shi Re Qin Xin (9.1%), Xin Mai Yu Zu (6.5%), Xin Yang Bu Zu (5.4%).3. The differentiation of TCM syndromes distribution between different stage of age has no statistical significance (P>0.05).4. Xie Du Qin Xin is the most commonly encountered TCM syndrome during68acute stage, the differentiation of TCM syndromes distribution between acute stage and chronic stage has high statistical significance(P<0.01).5. The disease incidence of Xie Du Qin Xin (including Feng Re Fan Xin and Shi Re Qin Xin) declined with increase of course, the disease incidence of Qi Yin (Yang)Kui Xu (including Qi Yin Liang Xu and Xin Yang Bu Zu)and Xin Mai Yu Zu ascended with increase of course. The tendency of TCM syndromes incidence has high statistical significance (P<0.01).6. The TCM symptoms and physical signs having more groups with statistical significance in multiple comparisons are: hypodynamia (6 groups), cacochroia (Sgroups), chest distress (8 groups), pectoralgia (4 groups), fever (4 groups), red throat (7 groups), nausea (4 groups), tongue coat (8 groups), pulse and fingerprint (9 groups).7. Discriminant function:(1)Feng Re Fan Xin=-12.750+0.739 hypodynamia+0.216 cacochroia+0.992 chest distress+ 0.917 pectoralgia + 1.114 pulse(fingerprint) + 8.569 throat+1.656 nausea+0.657 tongue coat+0.005 course(2)Shi Re Qin Xin= -12.484 + 0.678 hypodynamia + 0.257 cacochroia +1.771 chest distress+ 0.710 pectoralgia+ 0.729 pulse(fingerprint) + 4.317 throat+ 6.141 nausea+3.172 tongue coat+0.004 course(3)Qi Yin Liang Xu=-11.453+2.606 hypodynamia+0.792 cacochroia+0.157 chest distress+ 0.556 pectoralgia + 1.468 pulse(fingerprint) + 1.493 throat + 0.763 nausea+1.652 tongue coat+0.012 course(4)Xin Yang Bu Zu=-20.630+1.185 hypodynamia+1.758 cacochroia+2.249 chest distress + 0.490 pectoralgia+ 2.317 pulse(fingerprint)+ 2.385 throat+1.908 nausea?.177 tongue coat + 0:026 course-(5)Xin Mai Yu Zu= ?2.468 + 0.375 hypodynamia + 2.222 cacochroia+ 2.820 chest distress+ 3.239 pectoralgia+ 3.089 pulse(fingerprint) + 2.903 throat+ 7.993 nausea+0.652 tongue coat+0.026 courseConclusion: The commonly encountered TCM syndromes of mild and moderate pediatric virus myocarditis can be summarized as: Feng Re Fan Xin, Shi Re Qin Xin,Qi Yin Liang Xu, Xin Yang Bu Zu, Xin Mai Yu Zu. Hypodynamia, cacochroia, chest distress, pectoralgia, fever, red throat, nausea, tongue coat, pulse (fingerprint) and course have better discrimination. The discriminant function can discrimi...
