Study of traditional Chinese medicine (TCM) syndromes is a key to the research of TCM modernization, and the core is the classification and diagnostic criteria of syndromes. The purpose of this article is to review the usage of classification algorithms of data mining in TCM syndrome researches, and comprehensively analyze the main features of algorithms and their applications. The appropriate classification algorithm should be chosen according to different research purposes. Rough sets and cluster analysis are suitable for exploratory research without requiring a prior knowledge. Fuzzy sets theory, neural networks and decision tree are suitable for syndrome diagnostic criteria research when the classification goal is clear, because they require a prior knowledge. Among them, fuzzy sets theory could be used in combination with other classification algorithms. Thus, some new methods such as fuzzy clustering, fuzzy rough sets or fuzzy decision tree might be more suitable for TCM algorithm classification research. It is suggested that some novel classification algorithms need to be developed to fit the condition of TCM syndrome, based on the interdisciplinary theories and technologies.

Background:Nipple discharge cytology is a simple non-invasive method that may provide valuable information for detecting underlying malignancy.Several studies have investigated the diagnostic value of cytology in breast cancer patients with pathological nipple discharge,but the results have been highly variable.Herein we presented a systematic review and meta-analysis of published studies pertaining to the diagnostic capacity of nipple discharge cytology in patients with breast cancer.Methods:A systematic literature search was performed (Medline/PubMed,Embase,Cochrane Library databases,and Google Scholar) to identify studies that investigated the diagnostic capacity of cytology with regard to breast cancer in patients with pathologic nipple discharge.Two independent researchers identified articles that assessed the sensitivity and specificity of cytological evaluation for breast cancer detection in patients with pathologic nipple discharge published between January 2000 and October 2018.Articles were only included in the meta-analysis if they met predetermined criteria.The characteristics of each study and the data they yielded were summarized.Quality assessment of all articles included was performed using the Methodological Index for Non-randomized Studies Criteria (MINORS) and the Quality Assessment of Diagnostic Accuracy Study 2 (QUADAS-2).Heterogeneity was tested via Cochran Q test and the I2 statistic using Stata 12.0 and Meta-DiSc 1.4 software,and meta-analysis was performed.Results:A total of 286 articles were identified,of which 12 articles including a total of 1476 patients were deemed eligible for inclusion in the meta-analysis.A random-effects model assessing the capacity of nipple discharge cytology to predict breast cancer yielded pooled sensitivity 63％ (95％ confidence interval [CI]:53％-72％),specificity 95％ (95％ CI:87％-98％),positive likelihood ratio 12.35 (95 ％ CI:4.87-31.34),and negative likelihood ratio 0.39 (95 ％ CI:0.30-0.50).The diagnostic odds ratio was 31.88 (95％ CI:11.30-89.98).The area under the summary receiver operating characteristic curve was 0.79 (95％ CI:0.75-0.82).Conclusion:The current meta-analysis suggests that nipple discharge cytology is a useful diagnostic modality for detection of breast cancer in patients with pathological nipple discharge,with moderate sensitivity and high specificity.

Objective To understand the effectiveness of China Infectious Disease Automated-alert and Response System(CIDARS)for outbreak detection at the regional level.Methods Two counties in Hunan province(Yuelu and Shuangfeng county)and two counties in Yunnan province(Xishan and Gejiu county)were chosen as the study areas. Data from CIDARS were analyzed on the following items: reported cases, warning signals, the time interval of signal response feedback, way of signal verification, outcome of signal verification and field investigation, from July 1,2008 to June 30,2010. Results In total, 12 346 cases from 28 kinds of diseases were reported,and 2096 signals of 19 diseases were generated by the system, with an average of 4.94 signals per county per week. The median of time interval on signal verification feedback was 0.70 hours(P25-P75:0.06-1.29 h)and the main way of signal preliminary verification was through the review of surveillance data(account for 63.07%). Among all the signals, 34 of them(1.62%)were considered to be related to suspected events via the preliminary verification at the local level. Big differences were found to have existed on the proportion of signals related to the suspected events of the total signals among the four counties, with Shuangfeng county as 4.71%, Yuelu county as 1.88%, Gejiu county as 0.95% and Xishan county as 0.58%. After an indepth study on the fields of suspected events, 12outbreaks were finally confirmed, including 5 on rubella, 4 on mumps, 2 on influenza and 1 on typhoid fever. Conclusion CIDARS could be used to assist the local public health institutions on early detection of possible outbreaks at the early stage. However, the effectiveness was different depending on the regions and diseases.
