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:Damage of intestinal mucosal barrier is a key factor in the development and progress of acute pancreatitis(AP),and is closely related with the prognosis of the disease. Aims:To investigate the protective effect and possible mechanism of mucoprotective agent teprenone on intestinal mucosal barrier in rats with experimental AP. Methods:Forty-five adult male Sprague-Dawley rats were randomly divided into normal control group(n = 5),AP model group(n = 20)and teprenone treated group(n = 20). AP model was established by subcutaneous injection of cerulein at abdominal wall. Rats in treated group were intervened with teprenone intragastrically before and after model establishment. ELISA was used for measurement of serum interleukin-1(IL-1),IL-6,tumor necrosis factor-α(TNF-α)and amylase;histopathological and ultrastructural changes of small intestinal mucosa were observed by light microscope and transmission electron microscope;Western blotting was used to detect the expressions of tight junction protein occludin and ZO-1. Results:Serum levels of IL-1,IL-6,TNF-α and amylase in AP model group were significantly higher than those in normal control group(P < 0. 05),accompanied by necrosis and exfoliation of small intestinal villus,widening of intercellular tight junctions and downregulation of occludin and ZO-1 expression. While in teprenone treated group,serum levels of proinflammatory cytokines and amylase were significantly decreased as compared with AP model group(P < 0. 05),the villus of small intestine remained intact,and dense tight junctions were observed. Expressions of occludin and ZO-1 in teprenone treated group were upregulated. Conclusions:Teprenone may protect against intestinal mucosal barrier injury in AP model rats by upregulating tight junction protein expression.

Objective To evaluate the effects of nerve growth factor-beta (NGF-β) pretreatment on cell apoptosis induced by endoplasmic reticulum stress during ischemia-reperfusion in isolated rat hearts.Methods Male Sprague-Dawley rats,weighing 180-220 g,were anesthetized with intraperitoneal 10％ chloral hydrate 300 mg/kg.The hearts were excised and perfused in a Langendorff apparatus with K-H solution aerated with 95％ O2 and 5％ CO2 at 37 ℃.Thirty-two isolated rat hearts were randomly divided into 4 groups (n =8 each) using a random number table:control group (group C),I/R group,NGF-β pretreatment group (group N) and NGF-β combined with K252a (trkA receptor antagonist) pretreatment group (group N + K).In group C,the hearts were continuously perfused with K-H solution for 195 min.The hearts were perfused with K-H solution for 45 min in group I/R.In N and N + K groups,the hearts were perfused with K-H solution for 15 min,and then with K-H solution containing 0.1 μg/ml NGF-β and 0.1 μg/ml NGF-β mixed with 100 nmol/L K252a,respectively,for 30 min.The perfusion was suspended for 30 min followed by 120 min of reperfusion with K-H solution in I/R,N and N + K groups.HR,left ventricular end-diastolic pressure (LVEDP),left ventricular developed pressure (LVDP) and + dp/dtmax were measured at the end of 15 min equilibration (baseline) and at 5,30,60 and 120 min of reperfusion.Myocardial specimens were obtained at 120 min of reperfusion for detection of myocardial apoptosis (by TUNEL) and expression of glucose-related protein 78 (GRP78),CCAAT/enhancer-binding protein homologous protein (CHOP),and caspase-12 (by Western blot analysis).Apoptosis index was calculated.Results Compared with group C,HR,LVDP and + dp/dtmax were significantly decreased,and LVEDP,apoptosis index and expression of GRP78 and CHOP were increased in I/R and N groups,and the expression of caspase-12 was upregulated in I/R group.Compared with group I/R,HR,LVDP,and + dp/dtmax were significantly increased,and LVEDP,apoptosis index and expression of GRP78,CHOP and caspase-12 were decreased in group N,and the expression of GRP78 was down-regulated in group N + K.There was no significant difference in cardiac function indexes between group I/R and N + K.Compared with group N,HR,LVDP and + dp/dtmax were significantly decreased,and LVEDP,apoptosis index,and expression of GRP78,CHOP and caspase-12 were increased in group N + K.Conclusion NGF-β pretreatment can protect the isolated rat hearts against ischemia-reperfusion injury,and inhibition of the endoplasmic reticulum stress-triggered cell apoptosis after activating trkA receptors is involved in the mechanism.
