Objective:In this study,we collected widely literature about treatment ofancient and modern stroke,applied the methods of modern computertechnology and statistics of combining, by the establishment of stroke diseaseprescription database,researched by using frequency,charts and othermathematical analysis methods,summarized and summed up the ancientphysicians on the stroke of the permit general awareness of the treatment oflaw and medicine characteristics and on the basis of the analysis of strokeprescription drug law, applied the unsupervised data mining technology toexcavate new prescriptions of stroke common syndromes and then used theexperiment to verify the validity,and opened new avenues for the discovery ofnew stroke compound medicines.Through the study to establish a compoundChinese medicine research and development mode about combination of datamining and the Chinese Medical Literature Analysis.Methods:1The study on ancient and modern literature of stroke medication rules1.1Established the stroke literature databasewe collected widely literature about treatment of ancient and modernstroke,sorted out in line with the literature included in the standard literaturerecords of855cases,normalized their symptoms,such as traditional Chinesemedicine name,collated and entered data in Epidata3.1software andtransformed into the SPSS18.0database with requirements of data mining andstatistical analysis, and then proceed to the next step database analysis.1.2The study on each historical period stroke medication rulesApplied the computer statistical software the SPSS18.0with frequencyanalysis method to comparative analysis on the stroke drug frequency of use,drug genus percentage,thus add up high frequency drug and high utilization drug genus percentage, and then infer the disease medication rules anddominant trend in the different historical period. Used the horizontal bar chartanalysis method to compare lateral various drugs flavor number and thepercentage of all drugs the percentage in the same dynasty, analyzed brieflystroke medication rules in same period;to compare vertical commonly usedclass of drugs of different dynasties to grasp stroke medication rules in history.2The research Based on unsupervised data mining technology stroke newdiscovery of prescriptionFrom855prescription stroke literature total database screenedrespectively syndrome of qi deficiency and blood stasis,syndrome ofobstruction of collateral due to wind-phlegm, syndrome of internal block ofphlegm-heat,syndrome of yin deficiency liver wind four syndromeprescription.Respectively entered each syndrome prescription to SPSS18.0software and processed data by the Institute of Automation, Chinese Academyof Sciences,Dr. Chen Jianxin designed unsupervised pattern discoveryanalysis software.Analyzed drug correlation by improved mutual information,entropy clustering method of complex systems,respectively obtained eachsyndrome commonly used drug pair and combination of core,assembledempirically drug pair and combination of core,obtained3new discovery ofprescription of each syndrome,and Traditional Chinese Medicine experts byresearching and discussing, identified new prescription in line with the clinicaltreatment of stroke each syndrome compatible law.3Based on unsupervised data mining technology stroke of syndrome ofqi deficiency and blood stasis new prescription—The effects of Shenlo-nghuoxuefang on experimental cerebral ischemia in rats neurological behavior, brain infarct area and the morphologyFocal cerebral ischemia model was developed with Male and female half SD rats of health clean grade. The animals were randomly divided into five groups: the sham group,the model group, Shenlonghuoxuefang high-dose (3.424g/kg d)group,low-dose(1.712g/kg d)group and the nimo-dipine (10mg/kg d) group. Using FeCl3patching a side of the middle c erebral artery established the model of focal cerebral ischemia. Sham group was only pushed aside meninges,not patching FeCl3.All groups wereirrigated before rats modeling7d, besides sham group and model groupwere gave isotonic Na chloride,Then each group was divided into twotime points:6h and7d (n=6). Beam Walking Test, Muscle Strength Test and Wrong Step Test were used for neurological behavior grading.HEstaining was used to detect the histomorphological changes of brain tissue and TTC staining was used to calculate the proportion of cerebral infarction area After cerebral ischemia7d.4The effects of Shenlonghuoxuefang on experimental cerebral ischemia ratsin the permeability of BBB and the protection of the mechanism of actionGrouping and modeling equivalent to3.The levels of L-1β,IL-10,SO-D,MDA in serum were tested through taking blood from peritoneal cavity,separating serum after rats cerebral ischemia6h and7d;Evens Blue(EB) assay was used to detect the permeability of BBB after rats cerebralischemia6h;Transmission electron microscope was used to observe thediversification of BBB ultrastructure after rats cerebral ischemia6h and7d;S-P immunohistochemistry and RT-PCR assessments were used to detect the protein and mRNA distribution and expression levels of tight junction-associated protein ZO-1,occludin, and claudin-5in all rats brain tissue.Results:1The study on each historical period stroke medication rulesOn the basis of the stroke literature database using frequency analysis method derived:Tang and Song dynasties ago,67flavors high-frequency drugs,Among them,exterior-releasing medicinal,tonifying and replenishing medicinal,wind-dampness-dispelling medicinal were used most frequently;Jin and Yuan dynasties,52flavors high-frequency drugs,tonifying andreplenishing medicinal,resolve phlegm drug,exterior-releasing medicinal,liver-pacifying and wind-extinguishing medicinal were used most frequently;Ming and Qing dynasties,70flavors high-frequency drugs,Among them,to nifying and replenishing medicinal,exterior-releasing medicinal,resolve phlegm drug,liver-pacifying and wind-extinguishing medicinal were used most frequently;Near the modern era,47flavors high-frequency drugs,Among them,tonifying and replenishing medicinal,liver-pacifying and wind-extinguishing medicinal,resolve phlegm drug were used most frequently;In the total database,78flavors high-frequency drugs,Among them,tonifying and replenishing medicinal,exterior-releasing medicinal,resolve phlegm drug,liver-pacifying and wind-extinguishing medicinal,wind-dampness-dispelling medicinal,blood-activating and stasis-resolving medicinal,warm the interior medicinal,heat-clearing formula,qi-regulating medicinal,orifice-opening medicinal etc.10kinds of drugs were used higher frequently.Using bar chart analysis methods Horizontal compared with the thedynasties various types of drugs flavor number and the percentage of a-ll medicines percentage (results with the frequency analysis method);Longitudinal compared with different dynasties commonly used drug classes,exterior-releasing medicinal were used most frequently before Tang andSong dynasties,on the contrary, in near the modern era;Using frequencyof wind-dampness-dispelling medicinal descended with time;Tonifying and replenishing medicinal were used frequency over10%of all drug use in the period,the highest in Ming and Qing dynasties;Liver-pacifying and wind-extinguishing medicinal were used most frequently;using frequency of resolve phlegm drug rised with time;Blood-activating and stasis-resolving medicinal and orifice-opening medicinal were used frequency changes little in the treatment of stroke during each period.2The research Based on unsupervised data mining technology strokenew discovery of prescriptionFrom the total database of ancient
