This paper is devoted to discussing two research patterns of biological basis of traditional Chinese medicine syndrome and presenting a research strategy for data mining methods. It points out that data mining methods which are based on feature selection are better fit for investigating biological basis of traditional Chinese medicine syndrome. Based on such a discussion, the concept of "characteristic pattern" is proposed to bridge the gap between "golden index" and biological basis of traditional Chinese medicine syndrome. This paper presents a novel research avenue for investigating biological basis of traditional Chinese medicine syndrome.

Objective To investigate the mechanism of treatment of lung cancer with Bacillus Calmette-Guerin Polysaccharides nucleic acid (BCG-PSN) combined with Cyclophosphamide(Cy). Methods 130 mice were divided into three groups (A,B and C groups). Gruop A was further divided into four subgroups . Subgroup A-1 was given normal saline orally 0.25mg/10g?d -1 ; Subgroup A-2 was given levomisole PO. 0.25mg/10g?d -1 ; Subgroup A-3 was given BCG-PSN PO.0.325mg/10g?d -1 and subgroup A-4 was given BCG-PSN by intra-abdominal injection 0.25mg/10g?d -1 . Group B was given identical drugs with group A, after fifth day given 20% sheep red blood cell 0.2ml by intra-abdominal injection for five days . Gruop C divided into five subgroups;Subgroup C1-4 were given same drugs with group A,then given 0.4% Cy by subcutaneous injection 0.25mg/10g?d -1 from fifth day to tenth day.Subgroup C-5 was normal contral group, was given normal saline 0.25mg/10g?d -1 PO and subcutaneous injection 0.25mg/10g?d -1 .Results Oral administration alone or intra-abdominal injection in subgroup A-4 obviously enhanced the phagocytosis of macrophages.The subcutaneous injection of Cy could obviously decrease anti-tumour immunity, including activity of interleukin-2 (IL-2),natural killer(NK) cell, lyphocyte trasformation, and macrophages phagocytosis. BCG-PSN could increase and rehabilitate above anti-tumour immunological function. Conclusions Combinative treatment of BCG-PSN with Cy could remarkable enhance the immunocompetence.This experiment may provide a theoretical evidence for BCG-PSN combined with chemotheapeutic agents applied to treat the lung cancer.

Objective To review the experience of minimally invasive incision for open-heart surgery in 56 children with congenital heart diseases.Methods There were secundum atrial septal defect (ASD)25 cases, ventrilcular septal defect (VSD) 26 cases, double-chambered right ventricle (DCRV) 2 cases and pulmonary arterial stenosis (PS) 3 cases,right anterior-lateral thoracotomy for 23 cases in heart beat CPB and ministernotomy for 33 cases participated in the study.Results No death or serious complications happened,and the patients' postoperative recovery rapidly,mean hospital stay was 8 days .Conclusions Minimally invasive incision has followe as advantages,such as :less trauma, cosmetic, less pain, recovery rapid, safeness, effectiveness, and shorter hospital stay,especially for repairing the secundum atrial septal defect, membranous or para-membranous ventrilcular septal defect.

This paper reported a rapid hydrolysis method of food protein using microwave oven and high pressure vessel technique. Tryptophan in hydroly-zate was determined by fluorimetric spectroscopy method. The hydrolytic agent was 5 M NaOH solution. Under the operative condition of the microwave oven (microwave output power 650W, 2 minutes 15 seconds and 65W 2 minutes) the highest tryptophan contents of the pure protein lysozymum and food SRM liver, cabbage and wheat flour were obtained. The results of the t-test showed that there was no significant difference between the tryptophan contents determined by using the operative condition of the microwave oven mentioned above and 145℃ 4h hydrolysis method. The recovery of the method was 93.3%-107%, and the coefficient of variation obtained by parallel determination of 10 lysozymum sample was 4.2%.

Purpose:To compare the survival and toxicities of concureent chemoradiotherapy followed by adjuvant chemotherapy in patients with N1 esophageal carcinoma. Analysis was made for reasons of failure in the patients with N1 esophageal carcinoma. Methods:From August 1998 to August 2000,65 eligible patients with N1 esophageal carcinoma were randomized into the following arms: 33 patients were randomized to concurrent chemoradiotherapy arm, 32 patients to radiotherapy followed by chemotherapy. The schedules of radiotherapy were the same, which were conventional fractionation, total dose 60～70 Gy. The regimen of chemotherapy all consisted of DDP and 5 FU,4 cycles. It started on the first day of radiotherapy, and 15 days after radiotherapy chemoradiotherapy was given. Results:The survival rates at 1,2 and 3 years were 60.2%,43.5% and 25.9% in the concurrent chemoradiotherapy arm, 66.3%, 22.5% and 11.3% in the radiotherapy followed by chemoradiotherapy arm, respectively ( P =0.109). 18.2% in the radiotherapy followed by chemoradiotherapy arm had grad Ⅲ esophagitis, while the concurrent group had 43.7% P

Objective To compare the clinical effects of transurethral plasmakinetic resection(TUPR) with transurethral resection of the prostate(TURP) for benign prostatic hyperplasia.Methods From October 2003 to July 2006,a total of 127 patients with benign prostatic hyperplasia was divided the into the TURP Group(n=62) and the TUPR Group(n=61) according to random number table by computer.1 case of neurogenic bladder and 3 cases of TURP failure were ruled out the study.Results As compared with the RTRP Group,the TUPR Group had less intraoperative blood loss[(78.5?46.2)ml vs(115.0?43.5)ml,t=4.511,P=0.000] and more weight of resected prostate[(60.5?29.3)g vs(45.9?30.5)g,t=2.709,P=0.008].The operation time in the two groups was similar[(93.4?35.5)min vs(81.3?46.3)min,t=1.629,P=0.106].There were no statistic differences in international prostate symptom score,quality of life,Qmax,residual urine and complication rate(2/61 vs 5/62).Conclusions Compared with TURP,transurethral plasmakinetic resection of the prostate has the advantages of less blood loss and more entire resection of the prostate,so it might be more effective.

Objective To explore the clinical value of digital radiography with dual-energy subtraction in diagnosis of coronary artery and valve calcification. Methods 920 patients(older than 70) was examined by GE Revolution XRD with chest dual-energy subtraction. The positive rate of calcification of 146 patients who were highly or generally suspected for coronary artery calcification in bone window's and high Kilovotor digital graph of dual-energy subtraction were compared with the result of 16 slices MSCT. Results 135 patients with highly suspected coronary artery calcification and 11 patients with generally suspected coronary artery calcification in bone window's digital graph were examined by 16 slices MSCT. In those 135 patients with highly suspected coronary artery calcification, 128 cases were proved to be positive with 16 slices MSCT. In those 11 patients with generally suspected coronary artery calcification, 3 cases were proved to be positive with 16 slices MSCT. In those 12 patients who were positive with coronary artery calcification in high Kilovotor graph, 10 patients were confirmed to have coronary artery calcification in MSCT. In those 134 patients who were negative with coronary artery calcification in DDR, 126 patients were confirmed to have coronary artery calcification in MSCT. Conclusion Dual-energy subtraction digital radiography can offer potentially important new information in the evaluation of coronary artery calcium.
