OBJECTIVE: To study the classification of common symptoms and the laws of syndrome element combination in 251 cases of stable angina pectoris (SAP) by using cluster analysis and corresponding-correlation analysis. METHODS: A total of 251 SAP cases were selected and their information from four diagnosis in traditional Chinese medicine was recorded. The classification of common symptom and the laws of syndrome element combination were investigated by cluster analysis and corresponding-correlation analysis. RESULTS: Twenty-five symptoms found in 251 SAP cases were divided into four types by cluster analysis: deficiency of heart qi, deficiency of spleen qi, deficiency of qi and yin, and phlegm accumulation and blood stasis. The deficiency of heart qi had the closest relation to phlegm accumulation and blood stasis. By corresponding-correlation analysis, the deficiency of qi had the closest relation to blood stasis, next was turbid phlegm and heat stagnation, and then deficiency of qi and deficiency of yin. CONCLUSION: Blood stasis due to deficient qi is the key factor in pathogenesis of SAP. Deficiency of qi plus blood stasis, deficiency of qi plus deficiency of yin, blood stasis plus turbid phlegm, deficiency of heart qi plus blood stasis plus turbid phlegm are common syndrome element combinations of SAP. It is proved that cluster analysis and corresponding-correlation analysis are the proper methods for studying laws of syndrome element combination.

ObjectiveTo study the way of famous TCM doctors to success in modern times. MethodsTotally 96 famous TCM doctors and 30 TCM masters (122 in total, and 4 overlapping) recorded in the book ofThe Way of Distinguished Veteran Doctors of TCM were set as samples in the study. Their learning life was employed as evidence, and the following information was analyzed and concluded:the provinces they come from, their approaches to success, the ages when they became useful, learning time before they became useful, the most influential books, whether they started with classical prescription.ResultsDistinguished veteran doctors of TCM mainly come from Jiangsu Province (21.31%) and Zhejiang Province (11.48%). Learning from other TCM maters (40.98%) and inheriting the family’s TCM knowledge (22.95%) were their main approaches to becoming useful. The learning years before they became useful were 10-15 years (32.81%) and 6-10 years (26.56%). They became useful mainly at the ages of 21-30 (57.58%). 65.98% (64/122) of them treatedTreatise on Febrile Diseases as the most influential book. ConclusionThe study will provide beneficial reference for talent cultivation of TCM colleges and universities.

Objective To study the TCM syndromes and diagnosis of patients after percutaneous coronary intervention(PCI).Methods The clinical epidemiological method was adopted in the study and the symptoms and signs including the manifestations of tongue and pulse of 143 patients after PCI were recorded for the variable cluster analysis.Results The most of frequently appeared symptoms and signs of patients after PCI were chest pain,chest distress,lassitude,irritability,frequent micturition at night,obesity,dark lips and ecchymosis on the tongue.The 6 involved syndromes of the patients were qi deficiency with phlegm retention,kidney deficiency with blood stasis,liver qi stagnation,qi deficiency of spleen,qi deficiency of heart,and deficiency of both qi and yin.The diagnostic points of each of them were set up.Conclusion Six syndrome type could be classified in patients after PCI,and analysis base on diagnostic information set up the diagnostic points.

Objective To investigate the role of smear examination of wound secretion in early diagnosis and treatment of gaseous gangrene after trauma.Methods The data of 10 881 patients,who were carried to our hospital more than one hour after injuries from April 2003 to April 2006,were collected.Smear examination of wound secretion had been performed in these patients.Results Among the 10 881 wounded patients,11 patients developed gaseous gangrene,taking up 0.10%.Among the 11 gaseous gangrene patients,5 were caused by vehicle crash,3 by machine,2 by stone,1 by gun-shot injury.As for the wounded locations,7(63.6%)patients were in lower extremity,and 3(27.3%)patients in upper extremity,and 1 patient in mandible with head and neck wounds.The onset time of gaseous gangrene was(3.3?2.2)d.The 11 patients were completely cured.Seven patients with open comminuted fracture and lost limb function were performed with wound limb amputation,3 patients with injuries without fractures and 1 patient with mandible combined head and neck wounds were immediately treated with surgical debridement,cephalosporins,and hyperbaric oxygen(HBO). Conclusion Gas gangrene was extremely rare in injury patients but it was life-threatening,so doctors should pay more attention.Cleaning-up the wounds and debridement were critical for prevention of infection,and HBO might serve as an useful assistant method.Smear examination of wound secretion was helpful in early diagnosis and treatment of gaseous gangrene after trauma.

Objective To investigate the clinical significance of CA19-9 and CEA detection in the diagnosis of pancreatic carcinoma.Methods From January 2003 to November 2005,serum tumor markers(CA19-9 and CEA)in 44 patients with pancreatic carcinoma and 64 healthy volunteers were detected by radioimmunoassay.Results The levels of CA19-9 and CEA were markedly higher in the patients with pancreatic carcinoma than in healthy volunteers(P＜0.01).The sensitivity of combined detection of CA19-9 and CEA was much higher than any single detection.While the specificity of combined detection of CA19-9 and CEA had no statistical difference when compared to a single detection.The levels of CA19-9 and CEA in the Ⅰ+ⅡA stage patients were of no significant difference as compared with those in the patients of ⅡB+Ⅲ+Ⅳ stage,whereas the sensitivity of CA19-9 and CEA in the patients of ⅡB+Ⅲ+Ⅳ stage but much higher than in those of Ⅰ+ⅡA stage.Conclusion The serum concentrations of CA19-9 and CEA are closely related to pancreatic carcinoma with the invasion of mesenteric artery and lymphatic and distant organic metastasis.Combined detection of CA19-9 and CEA can improve the diagnosis of pancreatic carcinoma.

The research and development of traditional Chinese medicine (TCM) injections is an important innovation of modernization of TCM, which has great clinical value and irreplaceability in medical enterprise of China. But reports of adverse events of TCM injections gradually increased in recent years and the security problems received much concern with the enlargement of its application range. The reasons include unreliable herb sources and unreasonable utilization, in which the former includes historical reasons and non-unified standard and the latter includes combined use of Chinese and Western medicine, misused dosage and formula not corresponding to syndromes. We should face the problems, and preventive measures should be worked out by pharmaceutical factory, doctors and government. The first one is strictly guarding the pharmaceutical preparation procedures with advanced pharmaceutical technology; the second one is advocating the idea of formula corresponding to syndromes to minimize the occurrence of adverse effects; and the last one is strengthening the postmarketing reevaluation and market supervising management.

Objective To test the degree of acceptance and understanding of the entries for patient reported outcomes of stagnation of qi and blood;To further optimize and modify the entries. Methods A small sample pre-survey and group interviews were used to get the feedback information abut entries of patients, then the panel discussed to modify entries according to the data information. Results After a small sample pre-survey and group interviews, 11 items for modification were obtained, including the rejection in physical pain, belching and so on. Through further optimization and modification, the entries for patient reported outcomes of stagnation of qi and blood covered 41 entries in physiological domain, 11 entries in psychological domain, 1 entry in independent domain, and 8 entries in social domain. Conclusion The core part of the entries for patient reported outcomes of stagnation of qi and blood was formed, which comprehensively reflects the connotation of stagnation syndrome of qi and blood.

Objective: 139 documents (10,646 cases of angina pectoris in patients with coronary heart disease) which were treated with traditional Chinese medicine (TCM) of angina pectoris were researched, the application and existing problems of TCM evaluation standards of the efficacy of angina pectoris were studied to determine constructive items (candidate indicatrix) of TCM evaluation standards. Methods: The efficacy evaluation database of angina pectoris was established by the literature search and the software Epidata2.0, recorded in the database, and statistical analysed. Results: There are many kinds of evaluation standards of TCM efficacy of angina pectoris, but the utilization rate of each standard is lower than 40%. The main constructive item in evaluation standards of angina pectoris should include: the effect of the disease, syndrome effects, physical and chemical indicatrix, important clinical event, quality of life, and so on. Conclusion: The current evaluation standards of TCM efficacy of angina pectoris can not meet the clinical needs. A received evaluation standard should be established. The evaluation of TCM efficacy of angina pectoris should adopt integrated multi-dimensional index system.

The anti proliferation effects of four different concentrations of tea polyphenols on PG cell lines were determined with MTT assay. Laser scanning confocal mircroscopy and flow cytometry techniques were used to determine the changes in intracellular calcium concentration, GJIC, Cx43 expression, and cell cycle distribution after treatment with tea polyphenols. The results showed that four different concentrations dose dependently inhibited the proliferation of PG cell lines. It caused a decline in the proportion of cells in S and G2/M phase, blocked the cell cycle progression in G0/G1 phase, and reduced the proliferation index of PG cell lines. Compared with control group, intracellular calcium concentration, GJIC and Cx43 expression were gradually increased ascended with an increase in tea polyphenols concentration. The results suggested that tea polyphenol could inhibit growth of PG cell lines. The mechanism of anti tumor is associated with an up regulation of GJIC of PG cell line.
