Objective: To study significance of detection of serum levels of high sensitive C reactive protein (hsCRP), tumor necrosis factor-α (TNF-α) and interleukin-8 (IL-8) for assessing patient’s condition in patients with coronary heart disease (CHD). Methods: Serum levels of hsCRP, TNF-α and IL-8 were measured in 78 CHD patients undergoing percutaneous coronary intervention (PCI) before and three months after PCI. Among CHD patients, there were 17 patients with acute myocardial infarction (AMI), 36 patients with unstable angina pectoris (UAP) and 25 patients with stable angina pectoris (SAP). Their levels of above indicators were compared with those of 47 healthy subjects (normal control group). Results: （1）Compared with normal control group, there were significant increase in serum levels of hsCRP [ (1.96±0.60) mg/L vs. (22.43±9.68) mg/L, (18.27±8.56) mg/L], TNF-α [ (11.26±3.82) ng/L vs. (60.12±19.37) ng/L, (40.33±15.48) ng/L] and IL-8 [ (48.26±20.87) ng/L vs. (120.36±33.32) ng/L, (105.92±34.2) ng/L] in AMI group and UAP group before treatment (P<0.01 all), and Pearson linear correlation analysis showed that hsCRP was positively correlated with levels of TNF-α and IL-8 (r=0.873~0.956, P<0.01 all); （2）Serum level of hsCRP in SAP group [(6.04±2.38) mg/L] was significantly higher than that of normal control group (P<0.01); （3）Compared with before PCI, there were significant decrease in serum levels of hsCRP[(13.89±6.13) mg/L vs. (2.06±1.42) mg/L], TNF-α[(38.26±14.27) ng/L vs. (13.76±4.12) ng/L] and IL-8[(98.96±32.9) ng/L vs. (50.12±19.85) ng/L] in CHD patients three-month after PCI (P<0.01 all), and they were no significant difference compared with normal control group (P>0.05 all). Conclusions: Detections of serum levels of hsCRP, TNF-α and IL-8 in CHD patients are of certain significance for diagnosis, treatment and prognosis prediction of CHD.

AIM: To investigate the effects of oral administration of Astragalus membranceus, mung bean and arsenolite on the toxic of the arsenolite induced rats and the possible mechanisms with metallothionein (MT). METHODS: All the rats were oral administration with arsenolite. The Astragalus membranceus and mung bean were compared with the cadmium chloride which induced MT synthesis. The contents of MT were determined by cadmium saturation method, the liver mRNA levels for MT 1, MT 2 were detected by RT PCR. The protective effects of renal and liver were observed by testing alanine aminotransferase (ALT), blood urea nitrogen (BUN) and serum creatinine (SCR). RESULTS: The contents of MT were accorded with the mRNA expression of MT 1, MT 2. Arsenolite, Astragalus membranceus and mung bean could induce the synthesis of MT, but the contents of MT which arsenolite induced were trace. The contents of MT significantly increased after oral administration of Astragalus membranceus and mung bean, especially in the Astragalus membranceus group (P

Objective To discuss the effect of small needle knife therapy on collagensⅠ and Ⅲ in the hypertrophic scar tissues that was subcutaneously transplanted into nude mice. Methods Six samples of human hypertrophic scar tissues without cuticle were subcutaneously transplanted into the back of 24 nude mice to create the animal models of hypertrophic scar. Ten days after of the operation,the mice were divided into control,0.1 mg/ml triamcinolone,0.2 mg/ml triamcinolone,and small needle-knife groups with 6 mice in each. Specimens of the scar tissues were collected in 14 days for immunohistochemistry to detect the collagen Ⅰ and Ⅲ. Results In all the groups,collagens Ⅰand Ⅲ distributed extensively in the cytoplasm of fibroblast and tissues. Image analysis showed that the concentration of collagens Ⅰand Ⅲ in 0.1 mg/ml and 0.2 mg/ml triamcinolone groups were significantly lower than those in the control (0.09?0.03,0.11?0.05 and 0.12?0.02,0.11?0.01 vs. 0.17?0.04,0.19?0.03,P0.05). Conclusions Small needle-knife therapy can reduce the concentration of collagens Ⅰand Ⅲ in transplanted hypertrophic scar tissues in nude mice.

Objective To examine the expression of p44/42 mitogen -activated protein kinase (p44/42MAPK) and Phospho-p44/42MAPK in cicatrix (hy pertropic scars and keloids) and to aim at exploring the role of activated p44/ 42 MAPK pathway in development of cicatrix. Methods In or der to analyse the differences, 10 samples of normal skin (NS), hypertropic scar s (HS) and keloids (K) were collected, and then the extracted cytoplasmic protei ns from each tissue were examined by Western blotting for p44/42 MAPK and Phosph o p44/42MAPK and immunohistochemical staining with specific antibodies was emplo yed to determine that in fibroblasts of K, HS and NS. Results There was no evident difference of p44/42MAPK in the tissues and fibroblas ts between cicatrix and NS, but Phospho-p44/42MAPK was obviously higher in cica trix than that in NS. In cicatrix, there was no evident difference of p44/42MAPK in tissues between HS and K, while in fibroblasts, Phospho-p44/42MAPK in K was much higher than in HS. Conclusion Activation of p44/42MA PK pathways involves in formation of cicatrix.

Objective To determine the prevalence of pain beyond the osteoporotic vertebral com-pression fracture (OVCF) in patients undergoing percutaneous vertebral augmentation and the response of pain to the treatment. Methods A retrospective study of 104 patients undergoing percutaneous vertebral augmentation (pereutaneous vertebroplasty and pereutaneous kyphoplasty) was performed to examine the lo-cations and severities of pain beyond the OVCF before and after operation. The Visual Analog Sscale (VAS,10-point scale) and Activities of Daily Living (ADL, 5-point scale) were used. Results Of the 104 patients, 48 (46.2%) suffered pain beyond the OVCF. The pain was firstly located in the sacrococeygeal region and buttocks (26.0%), secondly in the abdomen and sub-xiphoid process (10.6%) and thirdly in the flank, ribs and chest (9.6%) . For all the cases, the mean VAS score decreased from 8.9±0. 8 before vertebral augmentation to 2.9±1.4 after augmentation (t=37.410, P=0.000), and the mean ADL score decreased from 4.1±0.6 before operation to 2.0±0.7 after operation (t=25.331, P =0.000) . For the patients suffering pain beyond the OVCF, the mean VAS score decreased from 8.8±0.9 before vertebral augmentation to 2.8±1.5 after augmentation (t=23.722, P=0.000), and the mean ADL score decreased from 4.2±0.7 before operation to 2.0±0. 7 after operation (t=15.373, P=0.000). The decreases in VAS and ADL scores were not affected by the pain. Conclusion The pereutaneous vertebral augmentation can effectively relieve the pain beyond the OVCF.

0.05).Conclusion Breath-hold MRCP utilizing the SSFSE technique with high-quality images can accurately assess the level of obstruction and the causes of the obstruction in patients with obstructive jaundice, without the risks of endoscopic retrograde cholangiopancreatography(ERCP).This MRCP technique should be preferred a reliable and noninvasive imaging modality for the diagnosis of obstructive jaundice.

Background and purpose:Members of the NF-kappaB family of transcription factors could activate bcl-2 anti-apoptotic genes at the transcriptional level and then regulate cell apoptosis.The p53 tumor suppressor gene has a clear role!in both the regulation of cell cycle and expression of apoptosis-related bcl-2 family.There were few reports about the expression of NF-?Bp65,bcl-2,bcl-xL and their relationships with p53 and cell apoptosis in pancreatic cancer.The present study was designed to analyze the expression of the antiapoptotic molecules nuclear factor kappaB(NF-?Bp65),bcl-2 and bcl-xL in pancreatic ductal carcinoma(PC) and their correlations to the apoptosis index and p53 expression.Methods:Immunohistochemical analyses of P53 protein was performed on 25 cases of pancreatic ductal carcinoma and 9 cases of normal pancreas;Western blot was used to evaluate NF-?Bp65 protein and RT-PCR for bcl-2 mRNA and bcl-xL mRNA of 25 cases of pancreatic ductal carcinoma and 9 NP cases.The apoptosis was determined by TUNEL.Results:The positive rate of P53 protein was 56%(14/25)in PC tissues,significantly higher than that in NP tissues(P
