Objective To observe the effect of tetramethylpyrazine (TMP) on serum interleukin 8 (IL-8),interleukin 12 ( IL-12) and interleukin 33 ( IL-33) levels and MMP-10 and NF-κB protein expression in joint synovial tissues in rats with collagen-induced arthritis ( CIA) ,and further to investigate the mechanism for treating rheumatoid arthritis. Methods Rats were randomly divided into normal control group( n=10) ,model control group,dexamethasone group,low-dose of TMP and high-dose of TMP groups ( n=9 each) . The CIA model was established in all the groups except for the normal control group. Rats of dexamethasone group were give 2 mg.kg-1 of dexamethasone;Rats of low-dose and high-dose of TMP group were given 50,100 mg.kg-1 of TMP, respectively.The toe volume and arthritis index (AI) were used to evaluate joint inflammation. The levels of IL-8,IL-12 and IL-33 in the serum of rats were detected by ELISA. The expression levels of MMP-10 and NF-κB in joint synovial were detected by Western blotting. Results Compared with CIA group,the toe volume and AI were significantly reduced in high-dose of TMP groups and dexamethasone groups,and levels of IL-8,IL-12 and IL-33 and the expression levels of MMP-10 and NF-κB were decreased significantly (P<0.01). TMP (50 mg.kg-1) could obviously decrease the toe volume and the levels of IL-8 and IL-33. There was no statistical difference in other indices (P>0.05). Conclusion TMP at 100 mg.kg-1 showed obvious inhibition on CIA rats. The mechanism may be correlated to balancing the effect of proinflammatory factor and anti-inflammatory cytokines,improving immune function in rats,reducing joint synovial inflammation,and alleviating the destruction of the articular cartilage.

Objective To investigate the effect of butylphthalide (NBP) on H2S content and the expression of NR2B in the hippocampus of alcohol dependence rats. Methods A total of 84 SD male rats were randomly divided into 6 groups. Except for the normal group, other groups were subjected to alcohol solution with concentration of 6% ( V/V) for 28 d. Drug intervention began at the 14th day,and rats in the low,medium,high dose group were treated with NBP with a different concentration. Erden abstinence scoring was used to evaluate the rats withdrawal symptom. H2S content was measured in one side of hippocampus and CBS activity was tested in the other side of hippocampus. Hippocampus of 3 rats from each group was used to investigate NR2B mRNA level. Results Withdrawal symptom score ( 12.27 ± 1. 19),H2S content(30. 25 ±8.82), CBS activity (72. 44 ±7. 46) and NR2B mRNA expression( 19. 47 ±0. 86) in medium dose NBP group rats were lower than withdrawal symptom score(14.09 ±2.21) ,H2S content(44. 50 ±6. 65) , CBS activity(79. 06 ±4. 57) and NR2B mRNA expression (29. 13 ±1.39) in experimental control group (P<0.05). Withdrawal symptom score(12. 18 ±1.08) ,H2S content(33.00 ±5.38) ,CBS activity(67. 81 ±9. 37) and NR2B mRNA expression(23. 12 ± 1. 86) in high dose NBP group rats were lower than experimental control group (P < 0. 05). Conclusion NBP can reduce withdrawal symptoms of alcohol dependence rats,may be related to decreased expression of H2S/CBS system, and NR2B mRNA expression.

OBJECTIVETo investigate the causes, clinical features, therapy and treatment outcomes of recurrent hemoptysis in children and to improve the skills of pediatricians in the etiological diagnosis and treatment of recurrent hemoptysis in children.
METHODSThe clinical, laboratory, and imaging data of 39 children with recurrent hemoptysis between January 1996 and February 2013 were collected to retrospectively analyze the age of onset, etiology, amount of hemoptysis, imaging changes, treatment methods, and follow-up outcomes.
RESULTSIn the 39 children, including idiopathic pulmonary hemosiderosis (16 cases, 41%), pulmonary vascular malformation (8 cases, 21%), pulmonary arteriovenous fistula (7 cases, 18%), bronchiectasis (3 cases, 8%), pulmonary tuberculosis (2 cases, 5%), pulmonary cystic fibrosis (2 cases, 5%), and lung tumor (1 case, 3%). The contrast-enhanced lung CT scans and pulmonary and bronchial arteriography revealed varying degrees of lung imaging changes in 35 cases. Of all cases, 51% were classified as degree I, 28% as degree II, and 21% as degree III. All children were treated according to the etiology, with the disease controlled. During 0.5-5 years of follow-up, 3 patients with idiopathic pulmonary hemosiderosis were lost to follow-up, and the other cases did not develop hemoptysis again.
CONCLUSIONSIdiopathic pulmonary hemosiderosis is the main cause of recurrent hemoptysis in children. Contrast-enhanced lung CT scans and pulmonary and bronchial arteriography are important methods for the etiological diagnosis of recurrent hemoptysis in children. Treatment methods should be selected according to the etiology.

OBJECTIVETo investigate the changes of the levels of galectin-3 (Gal-3) in serum and bronchoalveolar lavage fluid (BALF) of children with asthma whose have different serum levels of 25-hydroxyl-vitamin D₃[25(OH)D₃].
METHODSFifty children with asthma between January 2013 and December 2014 were enrolled as the asthma group, and they were classified into 25(OH)D₃sufficient (n=7), insufficient (n=12) and deficient subgroups (n=31) according to the serum levels of 25(OH)D₃. Twenty children with abnormal airway or tracheal foreign bodies served as the control group. The levels of 25(OH)D₃, Gal-3 and total IgE in serum and Gal-3 levels in BALF were measured using ELISA.
RESULTThe serum levels of 25(OH)D₃in the asthma group were lower than in the control group (P<0.05). The 25(OH)D₃deficient subgroup displayed the highest percentages of neutrophils, eosinophils and epithelial cells in BALF, followed by the 25(OH)D₃insufficient subgroup and the 25(OH)D₃sufficient subgroup (P<0.05). The percentages of neutrophils, eosinophils and epithelial cells in BALF in the three subgroups were all higher than in the control group (P<0.05). In children with asthma, serum levels of 25(OH)D₃were negatively correlated with the percentages of neutrophils, eosinophils and epithelial cells in BALF (r=-0.683, -0.795 and -0.670 respectively; P<0.05); and a negative correlation was also seen between serum 25(OH)D₃levels and serum Gal-3 and total IgE levels (r=-0.759 and -0.875 respectively; P<0.05).
CONCLUSIONSThe children with asthma have low serum levels of 25(OH)D₃. 25(OH)D₃and Gal-3 may be involved in the airway inflammation and the development of asthma.
