Objective To evaluate the therapeutic effect of hydrogen-rich saline on allergic contact dermatitis (ACD) in mice and to explore its underlying mechanisms.Methods Forty mice were equally divided into 4 groups:control group,control treatment group,ACD group and ACD treatment group.ACD was induced by repetitive topical application of dinitrofluorobene (DNFB) to the left ear of mice on day 1,2 and 5.Hydrogen-rich saline was intraperitoneally given to the mice in the ACD treatment group at a dose of 5 ml/kg per day from day 1 to 5.On day 6,the mice were sacrificed,ear tissue was removed from them and subjected to measurement of thickness and weight,detection of tumor necrosis factor (TNF)-α,interleukin (IL)-6,IL-17 and interferon (IFN)-γ expression by enzyme linked immunosorbent assay,as well as numeration of inflammatory cells in lesions after hematoxylin-eosin (HE) staining.Data were processed by SPSS 18.0 software,and statistical analysis was carried out by one-way analysis of variance and least significant difference (LSD) procedure.Results Compared with the control group,the ACD group showed a significant increase in lesion score (7.33 ± 1.53 vs.0,P ＜ 0.05),differences in the thickness ((0.73 ± 0.15) mm vs.(0.13 ± 0.05) mm,P ＜ 0.05) and swelling degree (expressed as tissue weight:(18.67 ± 3.05) mg vs.(3.33 ± 1.52) mg,P ＜ 0.05) between the left and right ear,expressions of TNF-α ((1475.52 ± 233.81) pg/mg vs.(239.01 ± 52.39) pg/mg,P＜ 0.05),IL-6 ((184.65 ± 78.39) pg/mg vs.(42.28 ± 17.64) pg/mg,P＜ 0.05),IL-17 ((628.56 ± 201.44) pg/mg vs.(127.58 ± 50.28) pg/mg,P＜ 0.05) and IFN-γ ((197.72 ± 37.81) pg/mg vs.(24.57 ± 8.31) pg/mg,P ＜ 0.05),and the number of inflammatory cells per square millimetre in the left ear tissue (752.00 ± 166.06 vs.127.33 ± 77.18,P ＜ 0.05).However,hydrogen-rich saline treatment induced a statistical decrease in all of these parameters in the ACD treatment group compared with the ACD group,including lesion score (3.33 ± 0.58,P ＜ 0.05),difference in thickness ((0.46 ± 0.11) mm,P ＜ 0.05) and swelling degree ((11.00 ± 2.64) mg,P ＜ 0.05),expressions of TNF-α ((817.72 ± 101.13) pg/mg,P＜ 0.05),IL-6 ((95.86 ± 36.65) pg/mg,P＜ 0.05),IL-17 ((373.38 ± 126.74) pg/mg,P＜ 0.05),IFN-γ ((63.31± 17.38) pg/mg,P ＜ 0.05) and the number of inflammatory cells per square millimetre (384.00 ± 97.35,P ＜0.05).Conclusion Hydrogen may inhibit the release of inflammatory factors in ACD.

Objective To study the value of 256-slice spiral CT (MSCT) in internal thoracic artery. Methods The angiographic images of 107 patients who were suspected thoracic and abdominal aortic diseases were retrospectively ana-lyzed. The running rule and branches of internal thoracic artery on both sides were observed. Each side of the internal thorac-ic artery was divided into 3 sections according to the running rule. The lumen diameter, vessel length and its branches were measured in three segmental vascular of the internal thoracic artery. The lumen diameter of the diaphragmatic artery diame-ter,and the distance between internal thoracic artery and each border of the sternum were also measured. Results Both sides of the internal thoracic and diaphragmatic arteries were shown in 107 patients (100%). There were significant differenc-es in vascular lumen diameter of intrathoracic artery of both sides (P＜0.05). There were no significant differences between both sides of the corresponding segments (P>0.05). The left internal thoracic artery was significantly longer in the left side than that of right side (P＜0.05). There were no significant differences between the diameter of diaphragmatic arteries and the distance between the internal thoracic artery and the sternal edge of two sides (P>0.05). Conclusion The application of 256-slice spiral CT angiography can clearly show the running rule and anatomical features of internal thoracic artery ,and provide a relatively important clinical information.

Objective To investigate the expression of macrophage migration inhibition factor (MIF) in pulmonary tissues of the smokers with and without chronic obstructive pulmonary disease (COPD).Methods The subjects were assigned into three groups:non-smokers without COPD (control group,n =12),smokers without COPD (smoker group,n =13) and smokers with COPD (COPD group,n =16).The specimens were obtained from lung tissues as far away from cancer focus as possible (＞ 5cm).Real-time quantitative PCR and immunohistochemistry were used to investigate the expression and distribution of MIF in pulmonary tissues.The relationship between the severity of airflow obstruction and the differential expressions of MIF in lung tissues of the smokers with or without COPD was analyzed.Results (1) MIF mRNA expression in COPD group (4.87 ± 1.79) was higher than that in the smoker group (2.16 ±0.72;P＜0.01),which was higher than that in the control group (1.09 ±0.48;P ＜0.01).(2)Immunohistochemistry analysis showed that MIF protein expression in lung tissues of the COPD group (0.277±0.025) was higher than that in the smokers group (0.199 ±0.034;P ＜0.01),which was significantly higher than that in control group (0.130 ±0.021 ;P ＜0.01).(3) Correlation analysis of MIF mRNA expression in the lung tissues and pulmonary function parameters of forced expired volume in one second (FEV1) percentage of predicted (FEV1 pred) and ratio of FEV1 to forced vital capacity (FEV1/FVC) suggested that MIF mRNA expression in the lung tissues was negatively related with FEV1 pred (r=-0.578,P ＜ 0.01) and FEV1/FVC (r =-0.607,P ＜ 0.01).Conclusions MIF expression significantly increases in the smokers with COPD,and MIF level in the lung is positively correlated with airflow limitation.The results suggest that MIF may play an important role in the pathogenesis of smokinginduced COPD.

Objective To investigate whether hydrogen can regulate the expressions of inflammatory factors by ultraviolet B (UVB)-induced human HaCaT keratinocytes through the autophagy pathway.Methods Cultured HaCaT keratinocytes were divided into several groups:blank control group receiving no treatment,hydrogen group cultured in hydrogen-rich medium,three UVB groups irradiated with UVB at 1,10,50 mJ/cm2 respectively,three UVB + hydrogen groups irradiated with UVB at 1,10,50 mJ/cm2 respectively followed by culture in hydrogen-rich medium,UVB + 3MA group pretreated with the autophagy inhibitor 3MA for 1 hour followed by UVB radiation at 50 mJ/cm2,UVB + rapamycin group pretreated with the autophagy activator rapamycin for 1 hour followed by UVB radiation at 50 mJ/cm2,UVB + 3MA +hydrogen group pretreated with 3MA for 1 hour followed by UVB radiation at 50 mJ/cm2 and culture in hydrogen-rich medium,UVB + rapamycin + hydrogen group pretreated with rapamycin for 1 hour followed by UVB radiation at 50 mJ/cm2 and culture in hydrogen-rich medium.After additional culture with or without hydrogen for 12 hours,methyl thiazolyl tetrazolium (MTT) assay was performed to evaluate cellular proliferative activity,Western-blot analysis to measure the expressions of autophagy-associated protein 1 light chain 3 (LC3) and Beclin 1,and enzyme-linked immunosorbent assay (ELISA) to measure the supernatant levels of inflammatory factors including tumor necrosis factor (TNF)-α,interleukin (IL)-1β,IL-6 and high mobility group protein B1 (HMGB1),and a test kit was used to determine the level of lactate dehydrogenase (LDH).Results Compared with the blank control group,the 10-and 50-mJ/cm2 UVB groups showed significantly increased release of LDH,expressions of LC3 and Beclin1 and supernatant levels of TNF-α,IL-1 β,IL-6 and HMGB 1,but decreased cellular proliferative activity (all P ＜ 0.05).Hydrogen significantly attenuated the release of LDH,down-regulated the supernatant levels of TNF-α,IL-1β,IL-6 and HMGB1,but up-regulated cellular proliferative activity as well as LC3 and Beclin1 expressions in the 10-and 50-mJ/cm2 UVB + hydrogen groups compared with the 10-and 50-mJ/cm2 UVB groups respectively (all P ＜ 0.05).In addition,the levels of TNF-α,IL-1β,II-6 and HMGB1 were significantly higher in the 50-mJ/cm2 UVB + 3MA group than in the 50-mJ/cm2 UVB group,and higher in the 50-mJ/cm2 UVB + 3MA + hydrogen group than in the 50-mJ/cm2 UVB + hydrogen group,but lower in the 50-mJ/cm2 UVB + rapamycin group than in the 50-mJ/cm2 UVB group (all P＜ 0.05).Conclusion UVB radiation can increase the expressions ofautophagy-associated proteins,and hydrogen-rich medium can down-regulate the expressions of inflammatory factors by UVB-induced HaCaT cells through the autophagy pathway.
