Objective To investigate the frequency of t(14;18) in different subtypes of B-cell lymphomas and the ability of the polymerase chain reaction(PCR) to detect this rearrangement in frozen samples. Methods 107 cases of B-cell lymphomas were studied using DNA extracted from fresh-frozen tissues. The DNA samples were amplified by PCR for bcl-2 MBR/JH. The products of bcl-2/JH rearrangement were hybridized with an internal olignucleotide probe of bel-2 MBR. Results The rearranged bel-2MBR/JH gene was detected in 13 of the 25(52. 0%) follicular cen ter lymphomas, according to REAL classification: 8 of 11(72. 7%) grade 1 , 2 of 5(40. 0%) grade Ⅱ , and 3 of 90 (33. 3%) grade Ⅲ. 17 of 82(20. 8%) cases of diffuse large B-cell lympbomas were found to have detectable bcl-2 MBR/JH rearrangement. Conclusion The frequency of bcl-2 MBR/JH rearrangement in diffuse large B-cell lym phomas is significantly lower than those in follicular center lymphomas(χ2=9. 28, P <0. 005), suggesting that bcl 2/JH rearrangements occur mainly in follicular center lymphomas. In addition, the result of reconstruction experi ments suggest that amplification of bcl-2 MBR/JH rearrangements by PCR is both sensitive and specific for detection of t (14 ; 18 ) translocation.

OBJECTIVE:
To observe the therapeutic effect of radiotherapy combined with TPF in patients with nasopharyngeal carcinoma (NPC) and to explore the influencing factors on prognosis of NPC.
METHOD:
A retrospective analysis of 144 patients with nasopharyngeal carcinoma receiving radiotherapy combined with chemotherapy, from January 2006 to December 2011, was conducted. The survival analysis in patients with nasopharyngeal carcinoma were performed. The impact of age, sex, clinical stage, alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), lactate dehydrogenase (LDH), homocysteine (Hcy), uric acid, NK cell proportion, T cell proportion, Carbohydrate antigen on survival time was observed with univariate and multivariate methods.
RESULT:
By the last follow-up, 9 cases were lost . The follow-up rate was 93.75 percent and the average follow-up time were 54.67 ±17.17 (37-88) months. The age, clinical stage, LDH, proportion of T cells and NK cells were independent factor in patients with NPC with univariate analysis (P < 0.01). COX regression multivariate analysis revealed that age, clinical stage and LDH were strong risk factor affecting prognosis (P < 0.01) and the proportion of NK cells and T cells were protective factors (P < 0.01).
CONCLUSION
Radiotherapy combined with TPF is more effective than radiotherapy alone in patients with nasopharyngeal carcinoma . Age, clinical stage and LDH may adversely influence the disease prognosis, and NK cells and T cell proportion may act as protective factors.

Objeetive To discuss the correlation of creatinine reduction ratio(CRR2)from posttransplant day 1 to day 2 and early graft function recovery status after kidney transplantation. Methods Clinical data of 80 patients after renal transplantation from Jan 2005 to Mar 2007 were retrospectively analyzed.Patients were divided into three groups according to the post-operative serum creatinine level:53 patients within IGF group[cereatinine<265.2 μmol/L by post-operative day(POD)no.5],14 patients within SGF group(creatinine>265.2 μmol/L on POD no.5,but no need for dialysis),and 13 patients within DGF group(need for dialysis in the first week post-transplant).Then the value and 99%CI of CRRz of these three groups were calculated. Results The value of CRR2 of IGF,SGF and DGF was(46.8±14.6)%,(25.6±13.5)%and(0.7±17.7)%respectively.And CRR2 99%CI of IGF,SGF and DGF was 41%-52%,15%-36%and-14%-16 0A respectively.There was significant difference in the value of CRR2 among IGF,SGF and DGF group.So a criteria for early diagnosis of IGF,SGF and DGF by CRR2 99%C1 was established:IGF(CRR2≥40%),SGF (15%<CRR2<40%)and DGF(CRR2≤15%). Conclusion CRR2 has a good correlation with early graft function recovery after kidney transplantation,and can be used to predict the occurrence of SGF and DGF.

Objective:To understand the characteristics and explore the influencing factors of HBsAg positivity in methadone maintenance treatment (MMT) clinic patients.Methods:A face to face interview and medical record review were conducted in 1 040 patients at three MMT clinics in Guangxi from September to November in 2014. The questionnaire information included general demographic characteristics, drug use history, MMT status, sexual behaviors, and health status, etc. Blood samples were collected from the patients at the same time for the detections of the level of HBsAg, anti-HBs and anti-HCV. By using χ2 test, unconditional logistic regression model and Bayesian network model the influencing factors for HBsAg positivity in MMT clinic patients and the complex network relationship among these factors were explored. Results:A total of 1 031 MMT clinic patients were surveyed, the HBsAg positive rate was 11.35 % (117/1 031). The anti-HCV positive rate was 71.77 % (740/1 031), among the anti-HCV positive patients, the HBsAg positive rate was 10.27 % (76/740). After adjusting for the confounding factors, anti-HBs positive persons might not be HBsAg positive ( OR=0.05, 95 %CI: 0.03-0.09), and anti-HCV positive persons might not be HBsAg positive too ( OR=0.30, 95 %CI: 0.17-0.52) compared with anti-HBs negative and anti-HCV negative persons, respectively. The persons with family history of hepatitis B virus infection were more likely to be HBsAg positive compared those with no such family history ( OR=5.30, 95 %CI: 2.68-10.52). Bayesian network model analysis results showed that family history of hepatitis B virus infection and anti-HBs were directly related with HBsAg positivity. Anti-HCV, intravenous drug use in the past three months and other drug using during treatment were indirectly related with HBsAg positivity. Conclusions:Anti-HBs, family history of hepatitis B virus infection, anti-HCV, intravenous drug use in past three months and other drug use during treatment were related with the HBsAg positivity in MMT clinic patients. So, it is necessary to enhance health education, improve health awareness and decrease high risk behaviors to reduce the rate of HBV infection.
