[Syndrome Types of Chinese Medicine and Clinical Characteristics of 660 Patients with Diabetic Peripheral Neuropathy].

Objective To summarize the distribution and clinical characteristics of Chinese med- icine (CM) syndrome types in 660 patients with diabetic peripheral neuropathy (DPN). Methods Totally 660 inpatients at Department of Traditional Chinese Medicine, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences were recruited from Jan 2000 to Dec 2014. Their first diagnoses were DNP. The distributions of their syndrome types were observed. Clinical characteristics in patients with different syndrome types were compared. Meanwhile, Logistic regression analysis was performed in independent variable by taking syndrome types of CM as quartering regression variables. Results The ratio of syndrome types was sequenced from high to low as yin deficiency blood stasis syndrome [39.24% (259/660)], yang deficiency blood stasis syndrome [29.39% (194/60)], phlegm stasis in collaterals syndrome [19. 24% (127/660) ] , yin deficiency induced wind stirring syndrome [12. 12% (80/ 660) ]. There was no significant difference in the constituent ratio of CM syndrome patterns among groups with different courses of diabetes (P >0. 05). The ratio of yang deficiency blood stasis syndrome had an increasing trend as the course increased. There was significant difference in HbAlc, fasting C pep- tide (FCP) , systolic blood pressure (SBP) , total cholesterol (TC) , 24 h total urinary protein (24 h UCP) , serum creatinine (SCr), blood urea nitrogen (BUN) among patient groups with different CM syndrome types (P <0. 05). Compared with yang deficiency blood stasis syndrome, HbAlc increased, SBP,SCr,BUN and 24 hUCP decreased in yin deficiency blood stasis syndrome with statistical difference (P = 0. 006, 0. 002,0. 001 ,0. 001, and 0. 007; P <0. 05) ; 24 h UCP also decreased in yin deficiency induced wind stirring syndrome (P =0. 34, P <0. 05). Multiclassified Logistic regression showed that when taking yin deficiency blood stasis syndrome as reference, HbAlc was a protective factor of yang deficiency blood stasis syn- drome, 8 h urinary albumin excretion (UAE) was a risk factor. Both TC and SCr were risk factors for yin deficiency induced wind stirring syndrome. SCr was a risk factor for phlegm stasis in collaterals syndrome. Conclusions Poor control of blood glucose in DPN patients might be related with yin deficiency blood sta- sis syndrome. Patients with yang deficiency blood stasis syndrome might have longer course of disease, and were correlated with poorer control of SBP and renal function. DPN patients complicated diabetic ne- phropathy were more liable to have yang deficiency blood stasis syndrome.
