Objective To study the expression and its significance of Platelet-derived growth factor(PDGF) and Collagen type Ⅰ (Col- Ⅰ) mRNA in hepatic tissue in mice exposed to arsenic in drinking water. Methods Fifty mice were divided into control group, sodium arsenite group(iAs3+ group, 300 mg/L) and sodium arsenate group (iAs5+ group, 300mg/L) at random. The mice were sacrificed after 10 months for liver function test (ALT, AST and GLB examined by automatic biochemical analyzer) and pathologic examinations. Masson staining and immunohistochemical SABC methods were used. Through the result of Masson staining fibrosis semi-quantitative analysis of the fibrosis number was carried out in the per unit area. Using immuonhistochemical SABC methods, the expression of PDGF and Col- Ⅰ was detected. Results ①Serum ALT was statistically significant among control group [(36.67±3.51) U/L], iAs3+ group[(61.46±13.85) U/L] and iAs5+ group[(43.31±4.21) U/L, F= 6.56, P < 0.05], especially between the control and iAs3+ group (P < 0.05) ;Serum AST had a statistical significance among control group [(135.00 ± 20.42)U/L], iA3+ group [(510.86 ± 59.01)U/L] and iAs5+ group[(258.93 ± 22.40) U/L, F= 83.36, P < 0.05] ;Serum GLB had no statistical significance among control group [(20.86 ± 0.61)g/L], iAs3+ group [(26.94± 3.73)g/L] and iAs5+ group[(24.59 ± 5.27)g/L, F = 2.80, P < 0.05]. ②Masson staining revealed notable liver cell necrosis, regeneration, infiltration of inflammatory cells in portal area. Masson staining Semi-quantitative results showed significantly increasing size of fibrosis in model group. Compared with control group(0.069 ± 0.013) and iAs5+ group(0.143 ± 0.122), fiber hyperplasia of iAs3+ group(0.192 ± 0.108) had statistical significance (F = 1.91, P < 0.05). ③Immunohistochemistry results showed higher expression of PDGF in the portal area, sepetal and preisinus cells in model group. The heavy expression of Col- Ⅰ distributed in the surrounding of blood vessels and bile duet and along portal wall extensting to the liver in model group. Semi-quantitative results showed that PDGF among control group(202.79 ± 7.46), iAs3+ group(174.38 ± 7.71) and iAs5+ group(177.64 ± 7.81) had a statistical significance(F= 102.91, P < 0.05);Col-Ⅰ had a statistical significance among control group(200.11 ± 7.46), iAs3+ group (176.47±10.20) and iAs5+ group (177.378 ±7.948, F = 78.51, P < 0.05). Conclusions Exposed in oral drinking arsenic, mice can develop hepatic injury and hepatic fibrosis. The PDGF and Col-Ⅰ play significant effects on the process of hepatic fibrosis caused by oral drinking arsenic exposed mice.

OBJECTIVETo explore the features of various mediastinal lymphadenopathies using computed tomography perfusion (CTP).

METHODSCTP parameters (CTPs) of the selected mediastinal nodes from 59 patients with pathology-proven malignant lymph nodes and of those from 29 patients with clinically diagnosed or pathology-proven inflammatory lymphadenopathies were collected. Patients were divided into subgroups by etiology and phase of primary disease, including different pathological malignant nodes and diverse inflammatory nodes. CTPs were defined as blood flow (BF), blood volume (BV), mean transit time (MTT), permeability (PMB), and time to peak (TTP). Differences of CTPs were compared between malignant and benign nodes, and among subgroups, respectively.

RESULTSIn the mediastinum, no significant differences of CTPs were found between malignant and benign groups (all P>0.05), the same for subgroups of malignant nodes (all P>0.05). Acute lymphadenitis had higher BF and BV than chronic inflammatory, lymphoid tuberculosis, sarcoidosis and malignant nodes. The BF of malignant nodes was markedly slower than that of acute lymphadenitis (P=0.01), but faster than chronic inflammatory nodes (P=0.04) and sarcoidosis (P=0.03), with no significant difference compared with lymphoid tuberculosis. Pneumonia-complicated lymphoid tuberculosis showed the longest MTT while sarcoidosis displayed the shortest MTT, and inflammatory nodes, lymphoid tuberculosis without complicated pneumonia and malignant nodes had moderate MTT.

CONCLUSIONCTPs show promising potential in distinguishing various lymphadenopathies in the mediastinum, but more studies are needed to improve their specificity.

Objective To investigate the effects of Rhizoma Zingiberis Extract (RZE) on the cardiac functions of rabbits with heart failure. Methods Forty pure-bred New-Zealand rabbits were randomly allocated to 4 groups: control group, low-dosage RZE group, moderate-dosage RZE group and high-dosage RZE group. The rabbit model of heart failure was established by intravenous dripping of 20 g/L pentobarbital sodium. Oral tube perfusion of RZE was given after model establishment.The hemodynamic changes were observed before and after the modeling and 5,10,15,20,30,45,60,90,120,150 minutes after treatment by a RM-6000 4-graph physiological monitor. Results After treatment, LVSP, lv?dp/dtmax,lv +dp/dtmax,lv-dp/dtmax showed an ascending tend in all the groups, particularly in RZE groups; the differences between the control group and RZE groups were significant 30 minutes after treatment (P

Objective To investigate whether leukotriene D4 (LTD4) regulates eotaxin-3 (Eot-3) expression in bronchial epithelial cells, and study effect of pranlukst on the regulation.Methods BEAS-2B cells and normal human bronchial epithelia cells were pre- treated with LTD4 for 1 hour,stimulated with interleukin-4, the cells were incubated for 24 hours. Eot-3 protein in supernatant were measured by enzyme linked immunosorbent assay(ELISA). The cells were pretreated with pranlukast in different concentration, then the above procedure was repeated. Results The untreated bronchial epithelial cell expressed Eot-3 protein on a very low level. After stimulating with IL-4 and incubating for 24 hours, Eot-3 production increased significantly. Pretreating the cells with LTD4 enhanced the inducing effect of IL-4. Pranlukast inverted the upregulation of LTD4. Conclusions Upregulating the expression of Eot-3 induced by IL-4 on bronchial epithelial cells may explain partially the mechanism of leukotrienes involving airway allergic inflammation of asthma. The invertion impact on upregulation of LTD4 by pranlukast may be one of mechanisms that leukotrienes receptor antagonist cure asthma.
