Objective To develop techniques based on polymerase chain reaction(PCR) which can detect 2 of most common deletional ? thalassemia ? 3.7 deletion and ? 4.2 deletion in China accurately and speedily. Methods Two groups of primers were designed and synthesized. PCR conditions were optimized. The PCR pro ducts were analysed by 1.0% agarose gel electrophoresis. The gel was stained by EB and photographed using an UVP gel documentation. Results PCR product of a 1 700 bp DNA fragment with primers A′, B′, C3 indicates the ? 3.7 deletion while a 1 900 bp fragment indicates a normal or wild type of ? globin gene. Occurrence of the 1 700 bp and 1 900 bp simultaneously indicates a heterozygous of the ? 3.7 deletion. Neither of the 2 bands was presented, indicating a homozygous of South East Asia type of deletion (-? SEA ). According to patterns of 1 580 bp and 1 180 bp hand amplified by a PCR with primer G′, E, F′, we detected the ? 4.2 deletion and distinquished its heterozygous and homozygous. Conclusions The 2 PCR based techniques developed in our laboratory are accurate, simple, well reproducible and easy to use for screening of the 2 deletion types of ? thalassemia determinants.

Objective To develop a technique for the detection of genotypes of ?-thalassemia, which was rapid and automatical with high through-put.Methods The Real Time PCR and dissociation curve analysis (D.C) were carried out by using SYBR Green1 on ABI7000.Positive results of the 3 SYBR-Q-PCRs were defined by the -dF/t℃≥cut off value of the peak at the specific Tm for each right PCR product.Three PCR products were recombined with the T-vector.The correct positive clones were selected by sequencing.Standard curves of the CT vs. log values of copies were done from a serious dilutions of the recombinant plasmid DNA which served as the template in SYBR-Q-PCRs.Results The conditions of the PCR including concentrations of primers, thurmocycler program etc.were optimized.Specific Tm values for the 3 SYBR-Q-PCRs were 82.5?1℃, 83.0?℃ and 84.0?1℃ respectively. The standard curves for p800 bp and p206 bp DNA showed a good linear relationship between CT and log value of the copies of the template DNA ranging from 10~5 copies to single copy. Sensitivity of the technique were at least 10~1 to 10~2 times higher than that of the regular PCR plus gel electrophoresis method.The techniques and reagents showed very good reproducibility and stability besides the high sensitivity. The ?-thalassemia 1(??/--SEA), Bart′s Hydrops Syndrom (--SEA/--SEA), deletion type and non-deletion type of HbH diseases, and homozygote of ?-thalassemia-2 were diagnosed by the methods.Conclusion The genotypes of the ?-Thalassemia could be diagnosed by the Real-time PCR with SYBR Green1 combined with the melting curve analysis.rapidly, automatically, accurately with high throughput and without dual fluorescent labeled probe.

Objective To evaluate the expression of WWOX gene in breast cancer and its relation to hypermethylation of WWOX gene CpG island. Methods The expression of WWOX protein was evaluated by immunohistochemical staining in breast cancer cell line and breast cancer tissues.Methylation specific PCR(MSP)was used to check whether it Was methylated in the promoter and exon 1 of WWOX.Results Deletion in the WWOX expression was observed more frequently in invasive breast tumors,(32.2%)than normal breasttissues(5.4%)(P＜0.01).20.3% of premenopause eases were completely negative for WWOX expression compared to 57.2% of postmenopause breast carcinomas(P＜0.01).Furthermore,23.1% of Stage Ⅰ(6/26),28.6%of Stage Ⅱ(10/35),46.2%of Stage Ⅲ(12/26)tunlors showed negative WWOX protein expression.In breast cancer specimens.methylation rate of promoter and exon 1 CpG island of WWOX gene was 55%and 45%respectively.Whereas.WWOX CpG islands of normal mammary tissues were completely unmethylated in all cases.CpG islands of WWOX promoter and exon 1 were methylated in MDA-MB-231 cell line but not MCF-7 cell.Conclusions Some deletion in WWOX expression is common in breast cancer and methylation of WWOX DNA CpG islands plays a crucial role in the silence of WWOX.WWOX may play a role in the carcinogenesis and development of breast cancer.

OBJECTIVESTo observe the efficacy of high intensity focused ultrasound (HIFU) in the treatment of late-stage pancreatic carcinoma and evaluate its influence on cell-mediated immunity in the host.

METHODSFifteen patients with late-stage pancreatic carcinoma had their tumor tissue completely destroyed with HIFU. Evaluation of efficacy was made on the basis of clinical symptom changes, variations in tumor echo, changes in pancreatic amylase, serum CA19-9 and CA242, CD3(+), CD4(+) subsets, CD4(+)/CD8(+) ratios and NK cell activity.

RESULTSClinical symptoms such as pain were significantly alleviated, echo of tumor was enhanced with B-US, CA19-9 and CA242 were decreased and pancreatic amylase showed no change. Eating, sleeping and mental status were all markedly improved; no serious complications were seen. On the other hand, NK cell activity was significantly enhanced in 10 patients (P < 0.05), and CD3(+) and CD4(+) subsets as well as CD4(+)/CD8(+) ratios increased to different degrees.

CONCLUSIONSThe use of HIFU in the treatment of late-stage pancreatic carcinoma is feasible and safe. It is effective in destroying the carcinoma and alleviating abdominal pain; it may enhance cell-mediated immunity in the host. This technique may offer a noninvasive therapy for the treatment of late-stage pancreatic carcinoma.
