Objective To explore the effects of surgical castration and intermittent androgen blockade (IAB) in patients with advanced prostate cancer.Methods 115 cases of advanced prostate cancer were selected including 48 cases with drug castration receiving IAB and 67 cases with surgical castration.Before the treatment, 6 months and 1 years after the treatment, the quality of life of the two groups was investigated by the quality of life questionnaire (EORTC QLQ-C30 +QLQ-PR25).Results Compared with before treatment, the general health status of the patients in the drug castration group and the surgical castration group were significantly improved (P<0.01), the whole body and the local pain were relieved (P<0.01) and the micturition symptoms were controlled ( P<0.01 ).The overall quality of life of drug castration group and surgical castration group were significantly decreased (P<0.05), and the degree of sexual function was particularly affected (P<0.01), but the body function of patients in drug castration group restored to a certain extent in drug castration group after 1 year’s treatment(P<0.01), while the quality of life in patients of surgical castration did not reverse.Conclusion Both of surgical castration and androgen deprivation therapy can reduce the quality of life of patients with advanced prostate cancer, but the adverse effects of drug treatment on the quality of life can be recovered in treatment intermission.

Objective Interferon regulatory factors 3 (IRF-3) is a key transcription factor to regulate gene expression of interferon after virus infection. This study aims to look for new spliced isoforms of IRF-3 and to investigate their structures and functions. Methods RNA extracts from human embryonic kidney 293 cells were amplified by RACE and RT-PCR. New sequences were compared with published sequences of IRF-3 and murine EST database using bioinformatics method. A new sequence, IRF-3c, was subcloned into pcDNA3.1-flag. The IRF-3c/pcDNA3.1-flag plasmid was transfected in HEK 293 cells. Whole cell extract was analysed by Western blot and then probed with monoclonal Flag antibody. Luciferase assay was carried out by co-transfection with reporter plasmid, pGL2B with interferon ? promoter, and IRF-3c cDNA expression plasmid. At 16 hours posttransfection, cells were infected with Sendai virus for 8 hours. Cells were collected and assayed for luciferase activity. Results A novel spliced isoform of IRF-3, named IRF-3c was discovered. The new isoform is almost the same as IRF-3, except for the utilization of the 180 bp bases in intron 6 adjacent to exon 6. The first 2,3 and 4 bases are a stop codon, which may produce a protein with a truncated C-terminal stoped at amino acids 327. Western blot analysis confirmed an expected 44 kDa strong band. The new inserted bases can be found in murine EST database, suggesting a conservative function in evolution. The functional luciferase assay showed that IRF-3c inhibited the IFN? promoter activity to (around) 40%～50% as that of control after Sendai virus infection. Conclusions The discovery of a new isoform of IRF-3 provides a new insight into the functional regulation of IRF-3 family. It is a dominant-negative inhibitor for interferon ? promoter activity in the virus infection pathway, provides a mechanism for the fine-tuning of the virus-induced activation of the interferon response, and prevents interferon ? from its overexpression and its toxic effects. It is worthwhile to explore the role of IRF-3c in the pathogenesis of human diseases using IRF-3c’s specific sequence.

Objective To explore the inhibitory effect of mutant influenza A viruses to the activation of interferon regulatory factor 3 (IRF-3). Methods HEK293 cells were infected with A/FM/1/47,A/HK/1/68, A/HK/1/68-MA20, A/HK/1/68-MA20C and positive control Sendai virus (SV). Whether the slowly moved phosphorylation form Ⅲ and Ⅳ of IRF-3 appeared or not was compared by Western blot in cells infected with these viruses. Wild type of NS1 from A/HK/1/68 and mutant NS1 from A/HK/1/68-MA20 were subcloned into pcDNA3.1-flag respectively. They were transfected in HEK 293 cells respectively. At 16 hours posttransfection, cells were infected with Sendai virus for 8 hours. Whole cell extracts were analyzed by Western blot and then probed with monoclonal flag antibody to check the expression of NS1, or with anti-IRF-3 to observe the inhibitory effects of the wild and mutant NS1 to the activated IRF-3. Luciferase assay was carried out by co-transfection with reporter plasmid, pGL2B with interferon ? promoter, and wild or mutant NS1 cDNA expression plasmid. SV was used to infect these cells after the co-transfection. Results Only less virulent A/HK/1/68-MA20 and positive control SV can activate IRF-3. Activated form Ⅲ and Ⅳ of IRF-3 began to appear 9 hours post infection (h.p.i), and most significant activated IRF-3 appeared 23 and 26 h.p.i. Sequence analysis of NS1 of MA20 revealed that nucleotide position number 94 is mutated from T to C, and amino acid at position number 23 is changed from valine to alanine. Co-transfected with wild type NS1 made form Ⅲ and Ⅳ of IRF-3 almost disappear, but not mutant NS1. In the luciferase functional analysis, wild type NS1 can inhibit the luciferase activity of IFN-? promoter, which was induced by SV, to around 1/10. Again no inhibitory effects was observed of mutant NS1 in the luciferase assay. Conclusion The mechanism that A/HK/1/68-MA20 can activate IRF-3 is that point mutant NS1 abolished the inhibitory function of NS1.

High levels of RNase,polysaccharides and polyphenol compounds make isolation of high quality RNA difficult. Thus it is presented an effective RNA extraction method based on the nuclease adsorbent macaloid,poly vinyl pyrrolidone,and high concentration of KAc and ethylene glycol monobutyl ether,which has successfully extracted high-quality RNA from many materials difficult to RNA isolation,such as RNase-rich rabbit liver,plant and microbial tissues rich in polysaccharides,lipids and polyphenol compounds. This method was found to be better than the ones in common use-Trizol and Guanidinium isothiocyanate,the yield of which was at least three time higher. Furtherly,small RNA was enriched from total RNA sample from rice seedling through by repeat deposit which deals with high concentration of LiCl,PEG8000 and NaCl. The small RNA gained was confirmed to be used for following molecular biological research by RT-PCR with the primers designed on osa-mir-156 sequence from rice miRNA.
