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.

Corneal endothelial cell(CEC)is the most critical part for the cornea, of which activity can influence the postoperative vision.It is very important for the clinical cornea preservation considering the function and its self-purification of donor cornea.There are a variety of classical methods, which can significantly prolong the saving time of donor cornea with its good quality of CEC.We reviewed the published papers about present preservation methods of cornea, which can give us many suggestions for the clinical cornea preservation.

Objective To investigate the effect of Kangaroo care(KC)on diminishing neonatal pain during heel lancing. Methods Sixty neonates were divided randomly into two equal groups:intervention group and control group,which 30 cases in each group.In the intervention group,neonates were treated with KC(neonates were put in direct and continuous skin-to-skin contact with his/her mom)from 20 mins before heel lancing to 1 mins after the end of the lancing.In the control group,neonates were treated with regular care.The differences in heart rate,blood oxygen saturation,facial pain expression,crying duration and DAN(Douleur Aigue Nouveaune)scores between two groups were compared at 7 time points from 10s before the heel lancing to 10s after the lancing. Results The results of repeated measu te at 7 time points after heel lancing.There were significant interaction effect between time and main effect(P<0.01),which showed that the heart rate of two groups were not equal at different time points.Compared with the time effects(P<0.01)which showed that two groups of neonatal heart rate of the two groups would accelerate with time extension. There were significant differences(all P<0.05)in heart rate at 7 time points between two groups and smaller heart rate varied range in intervention group.The results of repeated measures analysis for neonatal blood oxygen saturation at 7 time points after heel lancing. There were significant interaction effect between time and main effects(P<0.01),which showed that the blood oxygen saturation of two groups were not equal at different time points.Compared with the time effect(P<0.01),which showed that two groups of neonatal blood oxygen saturation would reduce with time extension.There were significant differences(all P<0.05)in blood oxygen saturation of two groups at 30s,40s and 50s after heel lancing and smaller blood oxygen saturation varied range in intervention group.The crying duration and DAN scores in intervention group were significantly reduced compared with the controls(all P<0.05).Conclusions
Heel lancing could lead to moderate to severe pain of neonates.KC could effectively diminish the neonatal pain degree caused by heel lancing.

This paper introduces the nursing care of 1556 patients with nasal packing silicone ventilation tube after func-tional endoscopic sinus surgery. Meticulous nursing care during nasal packing silicone ventilation tube could alleviate patients' discomfort obviously. It was emphasized to suck at exact time according to the patients' demands, adopt effective suction means to alleviate the damage of nasal mucosa,such as suction in the tube or in the bottom of the tube, take measures to promote the cleaning of secretion,which could improve the breath and sleep,as well as shorten the time of recovery.

Objective To investigate the effects of COMT G472A genetic polymorphism on postoperative analgesia with fentanyl.Methods One hundred and twenty-nine ASA I or Ⅱ patients aged 19-71 yr undergoing operation on lumbar vertebrae under general anesthesia were enrolled in this study.Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the polymorphism of COMT G472A.The patients were assigned into 2 groups according to their genotypes:wild group and mutation group.Pain was assessed using VAS after the patients regained consciousness.When VAS score ＞ 3,the patients were given fentanyl 20μg iv every 5 win until VAS score was decreased to ≤ 3.PCIA was then started.The PCIA solution contained fentanyl 20 μg/kg + flurbiprofenaxetil 150-250 mg or propacetamol 4-6 g in normal saline 75 ml.The patients received a background infusion of 1 ml/h after a loading dose of 3 ml.The PCIA pump was programmed to allow a 0.5 ml bolus with a 15 min lockout interval.The amount of fentan yl infused in 24 h and 48 h was recorded.The amount of flurbiprofen (1 mg=fentanyl 1 μg) or propacetamol (1 g =fentanyl 37.5 μg) was transformed into fentanyl.Results Significantly less fentanyl was consumed in 48 h in mutation group ( n =49) than in wild group ( n =80).Conclusion COMT G472A is a factor contributing to the individual variation in patient' s response to postoperative analgesia with fentanyl.
