AIM: To explore the variation of blood biochemistry and arterial blood gas of patients with systemic inflammatory response syndrome (SIRS) in the early time after trauma and improve the diagnosis and first aid. METHODS: Eighty-eight patients with trauma from August 2003 to February 2004 were divided into two groups by their AIS-ISS90 score. The data of temperature, pulse, respiratory rate, white blood cell counts, Hb, blood glucose and arterial blood gas (PaO 2, PaCO 2, HCO 3 -, AG) were collected and compared with each group by statistic methods. RESULTS: Of the 88 patients, 49 underwent SIRS, 12 in light trauma group (ISS≥16) and 37 in severe trauma group (ISS45 mmHg or 0 05). 13 patients had MODS in severe trauma group and 2 died while none had MODS or died in light trauma group. CONCLUSION: Application of AIS-ISS90 and SIRS-related blood biochemistry and arterial blood gas is beneficial for the diagnosis and treatment for patients in the early time after trauma. [

Objective To investigate whether or not the pulmonary artery participates in the blood supply of lung cancer and its change of morphology and blood flow in lung cancer. Methods Two different colors of silicone were injected separately into the bronchial and pulmonary arteries of 33 rat models with squamous cell carcinoma of lung. The origin of blood supply of lung cancer and the morphologic change of pulmonary artery were observed under a stereomicroscope. The DSA of bronchial and pulmonary artery were performed simultaneously in 28 patients with lung cancer. Results The pulmonary branch of rat and patients were reduced, thinned and occluded in the affected lung. The pulmonary artery did not form tumor vessel, and pulmonary blood flow and perfusion were reduced or absent in the affected area. Conclusion The pulmonary artery didn′t participate in the blood supply of lung cancer. It is unreasonable to perform transcatheter chemo embolization for lung cancer via pulmonary arteriay.

Objective To study the effect of Chinese Herb of Yigan Granules in different dosages on bile secretion in rats.Methods The rats were randomly divided into 5 groups: blank control group,positive control group and high,mod erate,low dosages of Yigan Granules groups.The medicines were administered thr ough duodenal intubation for the rats.Then the volume of bile were gathered by common bile duct intubations in different time,and the volume of bile and the contents of bilirubin in bile were tested before and after given drugs.Results Yigan Granules increased the bile secretion in a dose-dependent manner and promote the secretion of bilirubin.Conclusion Chinese Herb of Yigan granules has a choleretic effect.

0.05). Estrogen was lower in the patients with AD than in the normal controls and there was a significant difference between the two groups (P

Background and purpose:Protein kinase C (PKC) is a potentially important target for cancer therapy due to its potential role in carcinogenesis. Abnormal expression and increasing activity of PKC-?are present in non-small cell lung cancer (NSCLC).The aim of this study is to investigate PKC-? protein expressions in lung cancer tissues by tissue microarray and their significance. Methods:Using tissue microarray, PKC-? protein expression in lung cancer patients was examined by immunohistochemistry. 182 samples of umor tissues and 18 samples of adjacent tissues were taken;of the 182 samples, 160 were NSCLC tissues and 22 were SCLC;102 samples from stage I cases and 58 from stageⅡ-Ⅲ cases.Results:Expression of PKC-? protein was observed in 48.3% (88/182) of cancerous tissues and 16.7% (3/18) of adjacent tissues (P

Objective To study the expression and signficance of the osteopontin (OPN) in epithelial ovarian cancer tissue and serum. Methods Immunohistochemistry method and ELISA were used to detect the expression of OPN in 64 cases of epithelial ovarian cancer tissue and serum, 20 cases of ovarian benign tumors and 10 cases of ovarian nomal tissues. Results The OPN expression was associated with the clinical staging and histological grading of epithelial ovarian cancer tissue and serum (P < 0.01). The level of OPN in epithelial ovarian cancer tissue was significantly higher than that in benign ovarian tumor and normal control groups (P < 0.01). Conclusion OPN is remarkably correlated with the carcinogenesis and the development of epithelial ovarian cancer.

BACKGROUND:A number of studies have shown that bone marrow mesenchymal stem cells can survive in the infarcted myocardium and improve cardiac function. OBJECTIVE:To investigate the effects of al ogeneic rat bone marrow mesenchymal stem cells on heart failure in acute myocardial infarction models of rats and possible mechanisms. METHODS:Rat bone marrow mesenchymal stem cells were isolated from the bone marrow of 39 male Wistar rats by density gradient centrifugation with Percol . After ligating anterior descending coronary artery, 39 female Wistar rats were randomly divided into three groups:control group (Dulbecco’s modified Eagle’s medium, n=12), mesenchyma stem cells group (n=15) and mononuclear cells group (n=12). Eight weeks later, hemodynamics and left ventricular function were measured. Histopathological and immunohistochemical examinations were performed. RESULTS AND CONCLUSION:Compared with the control group, left ventricular end diastolic pressure, left ventricular relative weight, the col agen volume fraction of type I and type III in the infarction zone of the left ventricle were al significantly decreased, in contrast to ±dp/dtmax,-dp/dtmax/left ventricular systolic pressure, body weight and vascular density in infarction zone were al significantly increased both in mesenchymal stem cells group and mononuclear cells group. There were no significant differences between two treatment groups except for interventricular septal thickness and vascular density in non-infarction zone. 5-Bromo-2'-deoxyuridine positive cells were observed in the infarction area of mesenchyma stem cells group but no positive cells in mononuclear cells group. Some bal-like cellmasses were found positively stained with desmin and cardiac troponin T. Results have suggested that embedded bone marrow mesenchymal stem cells survived in exogenous host hearts. The therapy of mononuclear cells and mesenchymal stem cells could limit the left ventricular remodeling after acute myocardial infarction and improve left ventricular function through angiogenesis inducing and col agen deposition decreasing.
