Patients with digestive malignant tumor always have their immune function, especially the cellular immunity, suppressed to a certain extent. Traditional Chinese medicine (TCM) holds that Pi-Wei is the essence of postnatal life, and the genesis and development of digestive tumor are chiefly due to the insufficiency of vital-qi, which makes the body open to the invasion of evil pathogens. Starting from regulating the immune function of organisms, researchers recently obtained some therapeutic effects by applying the Chinese recipe, Sijunzi Decoction, in the treatment of digestive malignant tumors. In this paper, the related studies on the concerned basic theory and clinical application were reviewed.

OBJECTIVETo investigate the relationship between body mass index(BMI) and blood pressure, blood lipid level, blood glucose, left ventricular structure and function in adolescents during transition period.

METHODSA vertical sectional survey on 193 pupils aged 7-11 years in primary school in 1996 was performed. 9 years later, the same research subjects aged 16-20 years were studied again in 2005. The subjects were divided into obesity,overweight and normal weight groups according to their BMI in 1996. Height, body weight, blood pressure, total cholesterol, triglyceride and blood glucose were collected and analyzed, and left ventricular structure and function were examined by echocardiography.

RESULTSBody mass index (24.71 kg/m(2)+/-4.57 kg/m(2), 20.54 kg/m(2)+/-2.84 kg/m(2) ), systolic blood pressure (117.22 mm Hg+/-17.44 mm Hg vs. 102.20 mm Hg+/-11.68 mm Hg), thickness of inter-ventricular septum and posterior wall (0.87 cm+/-0.12 cm vs. 0.77 cm+/-0.12 cm, and 0.91 cm+/-0.13 cm vs. 0.79 cm+/-0.31 cm), left ventricular mass and mass index (167.84 g+/-16.29 g vs. 128.95 g+/-63.00 g, and 88.12 g/m(2) +/-17.19 g/m(2) vs. 79.35 g/m(2)+/-39.01 g/m(2)) were found significantly higher in obesity group than in normal weight group 9 years later (P<0.05, P< 0.01 or P< 0.001). End diastolic volume and cardiac output were increased(P <0.05) and ejection fraction and fractional shortening decreased( P< 0.05). There were no differences found in cardiac diastolic function between the studied groups.

CONCLUSIONThe results suggested that simple obesity in childhood was an important cardiovascular risk factor when they grew into adolescents and adults. ;

OBJECTIVETo investigate the incidence and clinicopathologic significance of MSI and LOH on 3P in breast carcinoma and its precancerous lesions, intraductal papillary adenoma and ductal carcinoma in situ.

METHODS41 paired sporadic invasive breast carcinomas, 13 archival precancerous lesion specimens of the breast and 14 couples of benign hyperplasia were collected. Twelve microsatellites on chromosomes 2p, 3p, 5q, 6q, 16q, 17q, eleven markers on chromosome 3p were amplified for MSI and LOH, respectively, by polymerase chain reaction ( PCR ) with designed primers and detecting after polyacrylamide gel electrophoresis. In addition, the expression of protein of hMSH2, hMLHI, FHIT, ER, and PR were detected by immunohistochemistry.

RESULTSMSI was observed, at least two microsatellite markers, in 15 out of 41 (36. 6%) of the carcinomas, almost all belonging to poorly or intermediately differentiated carcinoma. Instability was shown in 9 of the 13 cases of precancerous lesions, but only 2 among them had more than 2 MSI sites. There was no MSI in benign hyperplasia. MSI was targeted predominately at D3S1766, D2S2739 in both carcinomas and precancerous lesions. Of the 11 loci examined, D3S1295, D3S1029 and D3S1038 were identified as the locus with most frequent LOH which were all correlated significantly with some clinicopathological parameters such as histological type, lymph node metastasis in breast cancer, while D3S1295 and D3S1029 were the most frequent markers in precancerous lesions. LOH of D3S1295 had significant correlation with negative expression of FHIT. Positive expression of hMLH1 and hMSH2 protein was detected in breast carcinomas in scattered distribution and their positive rate was 45% and 40% , respectively. In precancerous lesions, hMLH1 and hMSH2 protein showed diffuse expression and their positive rate was 61. 54% and 76. 92% , respectively, significantly lower than that in the control tissues.

CONCLUSIONDefective expression of MMR genes is closely associated with the development of breast cancer. Genomic instability might play a role in the early stage during multi-step mammary carcinogenesis. MSI indicates poor histological differentiation in breast carcinoma. D3S1766 and D2S2739 might be the sensitive sites to detect MSI in breast carcinoma and precancerous lesions. The smallest common LOH deletion regions seem likely to be situated between 3p14 and 3p25, indicating the existence of breast tumor related genes in those regions and some of them might affect tumor development.

Objective To identify heart failure(HF) symptom clusters and their transformation through the progress of disease. Methods A convenient sample of 200 HF patients were recruited in this longitudinal study. The Chinese version of Memorial Symptom Assessment Scale-Heart Failure(MSAS-HF) was used to collect data before admission,3 months after discharge,and 6 months after discharge. At each time point,symptoms with incidence rate above 15% were chosen for cluster analysis. Results HF symptoms before admission were divided into 4 clusters:emotional and digestive cluster,ischemic cluster,weary cluster,and congestive edema cluster. Symptoms at 3 months after discharge and 6 months after discharge fell into 2 clusters:sickness cluster and weary cluster. Dry mouth was not included in either clusters. Conclusion The distribution and structure of HF symptom clusters had changed a lot at different stages of disease. It suggests that pertinent interventions might be taken according to the pattern of changes of HF symptom clusters through the progress of the disease.

OBJECTIVETo investigate the role of surgery in the treatment of giant mass lung cancer and to analyze prognostic factors affecting surgical result.

METHODSFrom August 1992 to August 2005, the clinical data of 137 patients with giant mass lung cancer ( > or =8 cm in diameter) were retrospectively reviewed. 122 cases had radical resection with 63 lobectomies, 48 pneumonectomy and 11 other resection modes, the remaining 15 patients underwent palliative resection. The prognostic factors including sex, tumor size, p-TNM stage, T stage, N stage, histological types and operation extent were analyzed with SPSS 13.0 software. The survival rate was calculated by Kaplan-Meier method and logrank was used for comparing survival difference. Univariate and multivariate prognostic factors for survival were analyzed by Cox proportional hazard regression model.

RESULTSThe overall 1-, 3- and 5-year survival rate was 76.0%, 49.2% and 40.1%, respectively. Sex (P = 0.001), p-TNM stage (P = 0.001), N stage (P = 0.042), surgical approach (P = 0.026) and T stage (P = 0.006) were found to be prognostic factors in Cox univariate analysis. p-TNM stage (P = 0.001) were identified as an independent prognostic factor in Cox multivariate analysis.

CONCLUSIONp-TNM stage is the crucial prognostic factor in surgical treatment for giant mass lung cancer. Strict selection of candidate for resection and complete resection may be helpful in improving survival in patient with giant mass lung cancer.

OBJECTIVEThrough studying the difference between the hypertensive patients and those with normal blood pressure who all from the same hypertensive pedigree, we tried to find the factors which would decrease the risk of hypertension.

METHODSHypertensive patients, when coming to the cardiovascular clinic of Xuan Wu Hospital from 2003 to 2004, were defined as the members of the hypertensive pedigrees through inquiry. 84 families including 368 persons, with 192 syblings were involved. Metabolic syndrome could be defined by the criterion of adult treatment panel III.

RESULTSWhen compared with normal blood pressure persons, clinical examinations of the hypertensive patients had an higher levels of triglyceride, total cholesterol, glucose and body mass index (BMI). The hypertensive group showed higher ratios among male patients, smokers, alcohol drinkers, having irritable personality and high-salt-intake. Through logistic regression, overweight, smoking and irritable temperament showed positive relations with hypertension. The rate of metabolic syndrome was higher in hypertension group.

CONCLUSIONIt is important that either persons with normal blood pressure or hypertension should control their body weights (BMI) since the rate of metabolic syndrome in hypertension group was high.

This study was aimed to investigate the expression characteristics of two transcriptional factors in Ikaros family, Ikaros and Helios isoforms and their mechanism, as well as their correlation with clinical parameters, which play important roles in transcriptional regulation of hematopoiesis. Expression of Ikaros and Helios isoforms in a total of 163 patients with leukemia and correlations between Ikaros and Helios isoforms were analyzed by PCR. The results showed that different expression patters of Ikaros and Helios isoforms existed in leukemia patients, that is, Ikaros isoform (Ik-6) was predominantly expressed in acute lymphoblastic leukemia (ALL) with BCR/ABL fusion gene, while Helios isoform (He-i) was overexpressed in T-cell ALL patients. The results of cloning and sequencing demonstrated that the isoforms of Ikaros and Helios had different genetic alterations. The statistical correlation between these two isoforms not was found in this study, although interaction between Ikaros and Helios has been reported. It is concluded that although Ikaros and Helios belong to the same family with similar structure of zinc fingers, their isoforms have different expression profile, specific genetic alterations, and different clinical relevance in patients with leukemia. The connection and interaction between Ik-6 and He-i needs further research.
