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.

ObjectiveTo evaluate the changes of Ag-NORs in patients with gallbladder carcinoma.MethodsAg-NORs in the peripheral blood lymphocytes,bile lymphocytes and the mucosa of gallbladder were detected by a cell image analysis of KL-2 in 20 normal volunteers,90 cholecystitis cases, and 20 gallbladder carcinomas.

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

Aim To study the active constituents for the treatment of rheumatoid arthritis from the ethyl acetate extracts of the roots of Lasianthus acuminatissimus Merr. Methods Various chromatographic techniques were used to separate and purify the constituents. Their structures were established on the basis of 1D, 2D NMR and HRMS spectroscopic analyses and their preliminary evaluation of anti-inflammation effect on the release of β-glucuronidase was carried out. Results Eight compounds were isolated and identified as lasianthuslactone A ( 1 ) , codonolactone ( 2 ), 2, 5-dimethoxy-1,4-benzoquinone ( 3 ) ,uncargenin A (4) , nonadecyl alcohol (5) , 13-docosenoic acid (6) , tetracosanoic acid (7) and β-sitosterol (8). Compound 3 showed a significant inhibitory effect on release of β-glucuronidase rat polymorphous nuclear leukocytes activated by platelet activating factor (PAF). Conclusion Compound 1is a new one, the others were isolated from the plant for the first time and 3 is one of active antiinflammation compound in the plant.

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.

Objective To explore the effect of Xiao Ban Xu, a compound Chinese traditional medicinal prescription, on the expression of collagenⅠand Ⅲ of keloid fibroblasts in vitro. Methods Six samples of keloid fibroblasts (KFB) and 6 samples of normal fibroblasts (NFB) entered the study as experimental and control groups, respectively. With the application of Xiao Ban Xu (10?g/ml), the fibroblast culture system and the ABC immunocytochemical staining method were used to investigate the expression of collagenⅠand Ⅲ of KFB and NFB. Results The density of the staining of collagenⅠand Ⅲ in the experimental group was much higher than that in the control group, with (7675 4?825 5 vs 2305 2?320 4 and 10595 2?1311 5 vs 2434 8?356 9; t =13 37 and 12 66, P =0 00004 and 0 00005) or without (11113 1?1304 9 vs 3519 6?236 0 and 11157 7?1300 3 vs 2626 5?426 3; t =14 42 and 13 47, P =0 00003 and 0 00004) the addition of Xiao Ban Xu. Compared with blank control group, the density of the staining of collagenⅠand Ⅲ was degenerated greatly in the experimental group after 48 hours of application of Xiao Ban Xu (7675 4?825 5 vs 11113 1?1304 9 and 10595 2?1311 5 vs 11157 7?1300 3; t =10 31 and 4 68, P =0 0001 and 0 0054). Furthermore, the inhibition ratios of collagenⅠwas 30 7%, and the one of collagen Ⅲ 5 1%, in the experimental group. Conclusions The expression of collagenⅠand Ⅲ of keloid fibroblasts in vitro may be significantly more intensive than the one of normal skin fibroblasts. It seems that the expression of collagenⅠand Ⅲ, especially collagenⅠ, in keloid fibroblasts and normal skin fibroblasts in vitro may be suppressed greatly by the application of Xiao Ban Xu.

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.
