Detection of consensuses and treatment principles of diabetic nephropathy in traditional Chinese medicine: A new approach
Abstract
Objective
To
 propose and test a new approach based on community detection in the 
field of social computing for uncovering consensuses and treatment 
principles in traditional Chinese medicine (TCM).
To
 propose and test a new approach based on community detection in the 
field of social computing for uncovering consensuses and treatment 
principles in traditional Chinese medicine (TCM).
Methods
Three
 Chinese databases (CNKI, VIP, and Wan Fang Data) were searched for 
published articles on TCM treatment of diabetic nephropathy (DN) from 
their inception until September 31, 2014. Zheng classification and herb 
data were extracted from included articles and used to construct a Zheng
 classification and treatment of diabetic nephropathy (DNZCT) network 
with nodes denoting Zhengs and herbs and edges denoting corresponding 
treating relationships among them. Community detection was applied to 
the DNZCT and detected community structures were analyzed.

Results
A
 network of 201 nodes and 743 edges were constructed and six communities
 were detected. Nodes clustered in the same community captured the same 
semantic topic; different communities had unique characteristics, and 
indicated different treatment principles. Large communities usually 
represented similar points of view or consensuses on common Zheng 
diagnoses and herb prescriptions; small communities might help to 
indicate unusual Zhengs and herbs.

Conclusion
The
 results suggest that the community detection-based approach is useful 
and feasible for uncovering consensuses and treatment principles of DN 
treatment in TCM, and could be used to address other similar problems in
 TCM.

Introduction
In
 complex network theory, a social network is a social structure made of 
nodes (individuals or organizations) connected by edges to exemplify 
various relationships such as friendship, affiliation, or cooperation. 
Community detection is one of the fundamental tasks in social network 
analysis. It solves problems by studying groups rather than individuals.
 Finding a community in a social network is a function of identifying a 
group of nodes that interact with each other more frequently than with 
nodes outside the group.1
 The real-world significance of identifying such communities are, for 
example, that friends in the same group share more similar interests and
 interact with each other more frequently2; that community analysis has uncovered thematic clusters on the Internet3; and, in biochemical or neural networks, that communities may be functional modules.4
 Nowadays, social computing research has gradually shifted from its 
traditional research fields such as computer science and engineering to 
other fields such as health services and communications.5 He6 et al and Chang7
 et al extended social cooperation networks to the field of traditional 
Chinese medicine (TCM) based on a theory that different herbs work 
together in a complementary manner to treat a disease. Their research 
also presented a traditional Chinese herbal prescription formulation 
network (TCHPFN).
In China, TCM herbal formulas have been widely used to treat many diseases. Zheng classification and treatment (ZCT, bian zheng lun zhi,
 in Chinese) is a unique feature of TCM, and use of TCM herbal formulas 
must follow ZCT. Many studies have been conducted to illustrate that 
treatment based on Zheng classification can improve specificity and 
efficiency in both TCM and Western medicine. 8, 9 and 10 However, Zheng classification depends mostly on the observations, knowledge, and clinical experience of TCM practitioners.11
 Zheng diagnosis always varies from practitioners, leading to different 
formulas, although with equivalent efficacy. There might be underlying 
consensuses and treatment principles among TCM practitioners to guide 
their treatments. Therefore, we proposed a community detection-based 
approach to uncover the underlying consensuses and treatment principles,
 and tested the approach by applying it to the Zheng classification and 
treatment of diabetic nephropathy (DNZCT) data. We present the DNZCT 
network as a social cooperation network of different Zhengs and herbs, 
and analyze the potential communities in the DNZCT.
