Objective To assess the ability of interleukin-1 beta (IL-1?) antibody and tumor necrosis factor alpha (TNF?) antibody to prevent postoperative abdominal adhesion formation in mice.Methods 60 BALB/c mice were randomly divided into four groups: normal saline group(n=15), anti-IL-1? group(n=15), anti-TNF? group(n=15),and anti-IL-1? combined with anti-TNF? group(n=15). After an identical peritoneal injury operation, mice were treated using intraperitoneally with either normal saline or corresponding antibody at the time of abdominal closure. The mice were killed 20 days after operation, the abdominal incisions and the development of intra-abdominal adhesions were observed. Adhesion scoring was based on an overall assessment of the extent,location, and type of adhesion.Results Anti-IL-1? combined with anti-TNF? group had significantly lower adhesion scores (0 84?0 19) than that in other groups(P

Objective To explore whether an individual' s intention to gamble varied across different types of gambling. Methods A total of 373 Macau students completed a questionnaire survey on intention to gamble dealing with thirteen types of gambling,and exploratory factor analyses were conducted. Results The analyses showed two factors that had eigenvalues greater than one and explained a total of 59. 455 percent of the variance,with the largest factor explaining 32.59 percent. Participants' intentions to gamble were relatively lower in gambles of low counterparty with mean scores varying from ( 1.62 ± 1.13 ) to ( 2.20 ± 1.35 ), while the intentions were higher in gambles of high counterparty with mean scores varying from ( 2.34 ± 1. 39 ) to ( 3.02 ± 1.55 ). Conclusion Respondents' degree of intention to gamble was highly domain-specific, varying with the type of gambling.An individual' s intention to gamble is not consistent across all content domains, which implied that a potential gambler is not necessarily intended to gamble in all types of gambling.

ObjectiveTo study the protective effects of tumor necrosis factor α(TNF-α) antibody on liver ischemia reperfusion injury in rats. Methods120 SD rats were randomly divided into three groups, the normal control group(Group A,n=40), ischemia group(Group B,n=40) and TNF-α antibody group(Group C,n=40). After 60 minutes ischemia and followed reperfusion, the animals were killed at 0,1h,3h,6h,12h,serum concentration of alanine aminotransferase(ALT), malondialdehyde(MDA) was meassured and liver histopathology was observed. ResultsAfter ischemia reperfusion, the serum concentration of ALT and MDA in Group B significantly increased (P<0.01),and the hepatic congestion was obvious compared with Group A. Treatment of TNF-α antibody could significantly decrease serum concentration of ALT and MDA in Group C compared with Group B(P<0.01),and relieve hepatic congestion. ConclusionTNF-α antibody can suppress the inflammatory reaction, and protect injury induced by hepatic ischemia reperfusion in rats.

ObjectiveTo study the effect of aprotinin and tumor necrosis factor alpha(TNF-α) antibody on preventing postoperative abdominal adhesion in mice.Methods96 BALB/c mice were randomly divided into 4 groups:normal saline group(n=24),aprotinin group(n=24),TNF-α antibody group(n=24),and aprotinin combined with TNF-α antibody group(n=24).After an identical peritoneal injury operation,all mice were treated intraperitoneally with normal saline , aprotinin,TNF-α antibody and aprotinin combined with TNF-α respectively at the time of abdominal closure .The mice were killed 20 days after operation,the abdominal incisions and the development of intraabdominal adhesions were observed.Adhesion score was based on an overall assessment of the extent,location,and type of adhesions .ResultsAprotinin combined with TNF-α antibody group showed significantly lower adhesion score and 2-3 grade adhesion(advanced significant adhesion) rate was lower than that of other groups(P<0.01).Conclusions The intraperitoneal administration of aprotinin and TNF-α antibody can inhibit postoperative adhesion formation.

Bacterial canker caused by Pseudomonas syringae pv. Actinidiae is one of the most important diseases of kiwifruit (Actinidia chinensis) and leads to considerable yield losses. In order to obtain transgenic plants with resistance for 'Red Sun' kiwifruit to canker disease, a non-specific lipid transfer protein-like antimicrobial protein gene (LJAMP2) from motherwort (Leonurus japonicus) was introduced into 'Red Sun' kiwifruit through Agrobacterium-mediated transformation. After two days of co-cultivation with A. tumefaciens strain LBA4404 harboring 35S:LJAMP2, the transformed explants were transferred to the selection medium containing 25 mg/L kanamycin+3.0 mg/L BA+1.0 mg/L NAA. The regeneration efficiency of kanamycin-resistant shoots reached to 85%. All (100%) of kanamycin-resistant shoots rooted on half-strength MS medium supplemented with 0.8 mg/L IBA and a total of 40 regenerated plantlets were obtained. PCR and histochemical GUS activity analysis show that 23 of 40 lines (57.50%) were positive, suggesting that the LJAMP2 gene was integrated into the genome of 'Red Sun' kiwifruit. Taken together, we established an efficient genetic transformation method for 'Red Sun' kiwifruit using A. tumefaciens and the transformation frequency reached 5.11%. This protocol will be useful for the genetic breeding of 'Red Sun' kiwifruit for improvement of disease resistance.
