Objectives: To compare the clinicalpathological features and prognosis between premenopausal breast cancer patients aged of <35 and ${\geq}35$ years old. Methods: The clinical data and survival status of 1498 cases premenopausal operable breast cancer treated in our hospital from 2002.1 to 2004. 12 were collected, 118 cases were aged <35. They were divided into 4 groups: Luminal A, Luminal B, HER2-positive, Triple-negative. The disease free survival (DFS) and overall survival (OS) were identified. Results: The 5-year DFS and OS rates were significantly lower in age<35 than in $age{\geq}35$ patients. In the Luminal B, HER2-positive, Triple-negative group, the 5-year recurrence risk was higher in age<35 than in $age{\geq}35$ patients, and age<35 patients' 5-year death risk was higher only in Luminal B, Triple-negative group. Regardless of whether lymph node involved, age<35 patients had a bad prognosis in both DFS and OS. Conclusions: Compared with premenopausal age ${\geq}35$ breast cancer, age<35 patients had a worse outcome.

Double stranded targets on the cDNA microarray contain representatives of both the coding and noncoding strands, which will introduce hybridization competition with probes. Here, the effect of double and single strands of targets on the signal intensity and the ratios of Cy5/Cy3 within the same slide were compared. The results show that single stranded targets can increase the hybridization efficiency without changing the Cy5/Cy3 ratio. Based on these results, a new strategy was established by generating cDNA targets with asymmetric PCR, instead of conventional PCR, to increase the sensitivity of the cDNA microarray. Furthermore, the feasibility of this approach was validated. The results indicate that the cDNA microarray system based on asymmetric PCR is more sensitive, with no decrease in the reliability and reproducibility as compared with that based on conventional symmetric PCR.

A series of benzamide-based histone deacetylases (HDACs) inhibitors possessing N-(aminopyridine) residue as the zinc binding site of HDAC were synthesized and evaluated. Among these derivatives, compounds with N-(2-amino-4-pyridine) benzamide moiety have been found as the most potent ones. Moreover, introduction of appropriate substituents on the terminal aryl group acting as the surface-recognition domain could significantly improve the antiproliferative activity. In particular, the compound 4k possessed favorable pharmacokinetic characteristics and exhibited potent antitumor activity on xenograft model in mice at well tolerated doses, thus suggesting a good therapeutic index.

The breeding of domestic rabbits (Oryctolagus cuniculus) for human consumption has a long tradition in China. Infections that can affect the production of meat or even be transmitted from animals to humans are important to monitor, especially for public health reasons as well as for their impact on animal health. Thus, a total of 1,132 domestic rabbit sera from 4 regions in China were collected for serological screening for Encephalitozoon cuniculi and for Toxoplasma gondii by ELISA and modified agglutination test (MAT), respectively. Antibodies to E. cuniculi were detected in 248/1,132 (21.9%) sera tested while antibodies against T. gondii revealed a seroprevalence of 51/1,132 (4.5%). We believe that the present results are of epidemiological implications and public health importance due to the acknowledged susceptibility of humans to E. cuniculi and T. gondii infections. Therefore, routine screening tests of domestic rabbits are proposed considering the zoonotic potential of these parasites.

Increased accumulation of anthocyanins in transgenic potato tubers by overexpressing the 3GT gene

In order to explore a biotechnological method for improving potato tuber color and creating plants with increased anthocyanin contents, a potato UDP-glucose: flavonoid-3-O-glucosyltransferase (3GT) gene was inserted behind the GBSSI promoter of pBin19, and this construct was introduced into Solanum tuberosum L. cultivar De´sire´e plants by Agrobacterium-mediated transformation. Six independent transgenic lines overexpressing the 3GT gene were identified by PCR and Southern blot analysis from 18 kanamycin-resistant plants. Due to the expression of 3GT gene, the tuber color and the anthocyanin content were enhanced noticeably in the transgenic plants compared to the wild-type control plants. This result suggests that the 3GT gene can potentially be used to improve potato color and enhance levels of antioxidants in the diet.
