This study proposed to use Term Frequency - Inverse Document Frequency (TF-IDF) relative entropy as knowledge representation method between symptoms and syndrome. TF-IDF was originated from text mining. It was an important method in the automatic text categorization. TF-IDF also represented the automatic categorization idea in traditional Chinese medicine (TCM) syndrome. It was based on the fact that the higher frequency of one symptom in specific syndrome, the stronger ability to distinguish this syndrome (TF); and the more wide range of one symptom in all syndrome, and the lower ability to distinguish a syndrome (IDF). It was verified with specific examples.

Objective This paper has discussed the antibacterial、 antiviral and degrading poison property of TiO2 nanometer spray in air cleaning. Methods Viable count was carried out, the inactivation on hepatitis B antigen (HbsAg) and the degradation of formaldehyde were detected. Results The results demonstrated that the inactivation to Staphylococcus aureus, Escherichia coli were over 99%. Bacillus subtilis var. niger, Candida albicans and hepatitis B antigen(HbsAg) were inactivated to a certain extent. The spray may be used for degrading the formaldehyde in the indoor air. Conclusions These two kinds of TiO 2 nanometer spray may, to a certain extent, inactivate the pathogenic bacteria and HbsAg, and may degrade formaldehyde.

Objective To compare the differences between antrum and corpus in endoscopic and histological diagnosis in non-ulcer dyspeptic patients.Methods 132 cases from out-patient department who had been ordered to undergo gastroendoscopy for dyspepsia were enrolled in the study.After endoscopy,different signs including redness,erosion,intramural bleeding and rugal atrophy were described.Histological diagnosis was defined according to the classification of chronic inflammation,polymorphonuclear neutrophil activity,glandular atrophy,intestinal metaplasia,helicobacter pylori and dysplasia.The differences between antrum and corpus in endoscopic and histological diagnosis were analyzed.Results Redness and erosion under endoscopy,glandular atrophy and chronic inflammation in histological diagnosis were found more frequently in antrum than in corpus.P values were less than 0.001,0.01,0.001 and equaled to 0.025 respectively.Conclusion In functional dyspeptic patients,there are differences in the endoscopic and histological findings between antrum and corpus.Redness and erosion in endoscopic diagnosis,glandular atrophy and chronic inflammation in histological diagnosis are more common in antrum when compared with that in corpus.

Objective To analyze the therapy and prognosis of palindromic ovarian carcinoma. Methods The clinical data of 40 cases of palindromic ovarian carcinoma were reviewed retrospectively. Results After the first surgery, the mean recurrent time of the patients with remained tumors smaller than 2 0 cm was (37 26?11 79) months, and that of the patients with remained tumors larger than 2 0 cm was (7 88?1 49) months. There was a significnat difference in the mean recurrent time between the two groups of the patients with different size of remained tumors(P0 05). Conclusion The recurrence of ovarian cancer was related to the size of remained tumor. Secondary operation plus chemotherapy could improve the short-term survival rate of the patients with palindromic ovarian carcinoma.

Background Essential hypertension (EH) and type 2 diabetes mellitus (T2DM) are frequently co- existed.Previous studies proved that EH can cause arrythmia,whereas,the arrythmia and the structure changed in hypertensive patients coexisted with T2DM are scarely reported.Objective To study the characteristics and mech- anism of arrhythmia in essential hypertension (EH) patients with type 2 diabetes mellitus (T2DM).Methods One hundred sixty eight patients were groupped as follows:EH group (n=65),T2DM group (n=31),EH+T2DM group (n=52),and normal group (n=20).The clinical data,echocardiographies and 24-hour dynamic eletroear- diogram were determined in all patients.Results 1)Arrhythmia incidence in EH+T2DM group was a statistically higher compared to EH group and T2DM group(P

Objective:To observe the difference of results of treadmill exercise test (TET) between male smokers and non-smokers .Methods:A total of 200 men with long-term smoking ≥20 cigarette per day were screened from outpatients and treated as smoking group .Another 200 men with similar age ,who didn’ t smoke at all ,were regarded as non-smoking control group (control group) .There were no medical history for hypertension ,hyperlipidemia ,diabetes ,and were nega-tive for electrocardiography and color echocardiography (exclude left ventricular hypertrophy etc .organic heart disease) in two groups .TET results and incidence rate of acute myocardial infarction (AMI) within two years were compared between two groups .Results:Compared with control group ,there were significant rise in TET positive rate (37. 5% vs .57. 5% , P<0.001) and incidence rate of AMI (8.5% vs .17.5% ,P=0.007) within two years in smoking group .Conclusion:Risk of suffering from coronary artery disease is more high in smokers among men .
