To establish a sensitive and specific HPLC method for quality control of Radix Paeoniae Alba, HPLC method was applied for quality assessment of Radix Paeoniae Alba. HPLC analysis was performed on a Symmetry C18 column (250 mm x 4. 6 mm ID, 5 microm, Waters, USA). The mobile phase consisted of acetonitrile (solvent A) and water containing 0.1% (v/v) phosphoric acid (solvent B) at a constant flow rate of 0.8 mL x min(-1). An increasing linear gradient (v/v) of solvent A was used (t/min, % A): (0,10), (5,10), (25,15), (45, 22), (46, 65), (50, 80) and (60, 80). The column temperature was set at 25 degrees C. The chromatograms were monitored at 230 nm and the on-line UV spectra were recorded in the range of 190 - 400 nm. The HPLC chromatographic fingerprinting of Radix Paeoniae Alba, showing 11 characteristic peaks, was established from 28 lots of Radix Paeoniae Alba. The areas of main chromatographic peaks were found to complied with the following rule: paeoniflorin > 1, 2, 3, 4, 6-penta-O-galloyl-glucos > albiflorin > methyl gallate > other compounds. The chromatographic fingerprinting of Radix Paeoniae Alba with high specificity can be used to control its quality and assure lot-to-lot consistency.

OBJECTIVETo investigate the expression of indoleamine 2, 3-dioxygenase (IDO) in breast cancer and its correlation with clinicopathologic factors and prognosis.

METHODSThe expression of IDO, CD31, CD105 proteins in 40 specimens of breast cancer were assessed by immunohistochemistry.

RESULTSThe overexpression rate of IDO in breast cancer was 67.5% (27/40), and expression of IDO was closely associated with clinical stage and lymph nodes metastasis. The disease-free survival rate in patients with IDO overexpression was not significantly lower than that in patients with negative or low expression of IDO (P > 0.05). Moreover, the expression of IDO was positively correlated with CD105-labeled microvessel density (r = 0.659, P < 0.05).

CONCLUSIONSExpression of IDO is associated with clinical stage and lymph nodes metastasis, and microvessel densitty. IDO expression may promote the growth and metastasis of breast cancer, probably via the increased agiogenesis. A larger sample study is needed to verify whether the prognosis of beast cancer is significantly correlated with IDO expression.

Objective To study the clinical characters,management and the prognosis of patients with adenoid cystic carcinoma of the maxillary sinus. Methods The clinical data were analyzed retrospectively for 36 patients with adenoid cystic carcinoma of the maxillary sinus to evaluate the treatment results of different modalities. The contribution of every factors influencing on survival were also analyzed.Survival analysis was performed by life table method,comparison among/between groups was performed using log-rank test,and multivariate analysis was carried out using Cox proportional hazard model. Results The 5-year survival rate was 58.33% in all patients, while they were only 75.0% and 42.9% in stage Ⅲ and stage Ⅳ lesions respectively. The 5-year survival rate of 66.7% was obtained in patients who received surgery combined with radiotherapy, 71.4% and 12.5% respectively in those treated by surgery and by radiotherapy alone. Multivariate analysis indicated that stage, treatment modality,and the tumour residues in the primary treatment were the predict factors for the prognosis. Conclusions Advanced adenoid cystic carcinoma should be treated by combined surgery and radiotherapy. Stage,treatment approach and shortterm therapeutic response are the most important factors affecting the prognosis of the patients with adenoid cystic carcinoma of the maxillary sinus.

The outcome and influencing factors in the reversion of impaired glucose regulation(IGR)to normal glycemia(NG)after health education for one year were analyzed by the criterion of American Diabetes Association 2003.The results showed that the improvement of glucose regulation well accorded with the improvement of insulin resistance and islet 13-cell function.Fasting plasma glucose,fasting insulin,triglycerides, insulin resistance and islet?-cell function were the influencing factors for the reversion of IGR to NG.

The aim of this study was to explore the clinical effect and complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT) in hematologic malignancies through retrospective analysis of 75 patients (42 male, 33 female; aged from 13 to 72 years old) received allo-PBSCT from HLA matched (n=61) or haploidentical donors (n=14). 75 patients included 35 patients with chronic myeloid leukemia (CML), 30 patients with acute myeloid leukemia, 5 patients with severe aplastic anemia, 3 patients with acute lymphocytic leukemia, one patients with multiple myeloma and one patients with paroxysmal nocturnal hemoglobinuria. Conditioning regimens were (1) Cy/TBI or Bu/Cy; (2) Cy/TBI+Ara-C; (3) fludarabine+TBI/or (CTX+ATG). Minimal residual disease has been monitored regularly by PCR and FISH. Patients received cyclosporine A and methotrexate or ATG and anti-CD25 monoclonal antibody and mycophenolate mofetil for graft-versus-host disease (GVHD) prophylaxis. Relapsing patients after transplantation received DLI and/or chemotherapy. Patient with CML were treated with imatinib. The results showed that 74 patients had hematopoietic reconstitution, and eventually converted to full donor chimerism by FISH or PCR-STR. The median time for the initial hematopoietic reconstitution was 15 (5-25) days. 46 out of 75 patients were alive and median duration was 23 (2-61) months. Among 29 dead patients, 9 died of disease relapse, 7 died of III-IV grade of acute GVHD and 7 died of severe infection (2 patients developed interstitial pneumonia). 9 out of 14 patients received haploidentical transplantation were alive, and the time of event-free survival was 30 (6-53) months, the mean survival time of 5 died patients was 7 (2-17) months. 16 patients were infected by cytomegalovirus, 2 of them died of interstitial pneumonia. None of them suffered from veno-occlusive disease in the liver. It is concluded that allo-PBSCT is effective to treat refractory hematologic diseases, and DLI/or chemotherapy should be used in the patients relapsing after transplantation.

OBJECTIVETo determine the value of elective neck dissection in patients with clinically stage I (cT1N0M0) squamous cell carcinoma of the tongue.

METHODSThis was a retrospective study of patients with surgical treatment between November 1984 and November 1999. A total of 130 patients were included in the study, all of whom received operation of the primary site, meanwhile, 99 of whom underwent elective neck dissection simultaneously including level I -III or level I -IV neck dissection in 20 patients and level I - V neck dissection in 79 patients. Results Among all these patients, the rate of occult metastasis to the neck were 12. 0%. Local failure rate in patients with only local treatment, level I II, II, III/IV neck dissection and level I - V neck dissection were 25. 8%, 15. 0% and 7. 6% respectively. There were significant difference in regional failure between patients with only local treatment and patients with elective neck dissection (P < 0.05). Also, no significant differences were noted in the survival rate between patients with only local treatment, elective neck dissection (level I -III or level I -IV) and level I -V neck dissection (P > 0.05).

CONCLUSIONSElective neck dissection significantly reduced regional control failure but was not able to reduce distant metastasis or increase the overall survival. A prospective randomized study is worthwhile to further evaluate the benefit of elective neck dissection in the treatment of clinically stage I squamous cell carcinoma of the tongue.

OBJECTIVETo investigate the influence of thymidylate synthase (TS) gene polymorphisms on high-dose methotrexate (HD-MTX)-related toxicities in childhood acute lymphoblastic leukemia (ALL).

METHODSA total of 73 children who were diagnosed with ALL between March 2011 and March 2013 were included into this study. Genomic DNAs were extracted from their peripheral blood. And then the genotypes of TS 5'-UTR were determined by direct DNA sequencing after PCR. The toxicity response of 73 patients receiving HD-MTX chemotherapy were observed and recorded, and plasma MTX concentrations at 42-48 hours after chemotherapy were measured.

RESULTSThe main HD-MTX-related toxicities of 73 patients receiving HD-MTX chemotherapy were neutropenia, decreased hemoglobin level, thrombocytopenia, liver toxicity, mucosal damage, and gastrointestinal reactions. There were no significant differences in the incidence rate of HD-MTX-related toxicities between children with different TS 5'-UTR genotypes after chemotherapy (P>0.05). TS 5'-UTR genotype was not significantly correlated with plasma MTX concentrations at 42-48 hours after chemotherapy (P>0.05).

CONCLUSIONSTS gene polymorphisms have no influence on the incidence of HD-MTX-related toxicities in childhood ALL.

Objeetive To evaluate the impact of viable myocardium assessed by 99Tcm-MIBI SPECT and 18F-flourodeoxyglucose(FDG) PET imaging in patients with left ventricular aneurysm(LNA) underwent revascularization (RVS).Methods Forty-six consecutive patients with LVA (mean LVEF 36%±7%),underwent 99Tcm-sestamibi SPECT and 18F-FDG PET examinations and received RVS therap,were followed-up for a mean period of 80±27 months.Viable myocardium in anenrysm was defined as perfusionmetabolism mismatch score (MMS) ≥2.0.Patients were divided into four groups by aneurysm viability and aneurysmectomy.Group A1 (n=8):viability-;Group A2 (n=15):viability-,aneurysmectomy;Group B1 (n=10):viability+;and Group B2 (n=13):viability+,aneurysmectomy.Results The cardiac event rates during follow up were similar among groups [A1(25%,2/8),B1(40%,6/15),A2(20%,2/10) and B2(31%,4/13:P＞0.05].After revascularization,LVEF was impmved (＞10%) in groups A2,B1 and B2(P＜0.05).Multivariate logistic regression analysis showed that LV-MMS(OR=2.34,95% CI 1.08-5.06,P＜0.05).distal vessel disease(OR=0.008,95% CI 0.001-0.560,P＜0.05) and nonaneurysm perfusion score (OR=0.24.95% CI 0.07-0.85.P＜0.05) were significantly associated with the improvement of LVEF after revascularization.Conclusions Long term cardiac events rate post revascularization was not affected by viable myocardium or aneurysmectomy in LVA patients.Viable myocardium in LVA patients was associated with better LVEF improvement after revascularization.

Objective To determine the value of concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma from the mainland of China. Methods Data were extracted from randomized trials comparing chemotherapy plus radiotherapy with radiotherapy alone in locally advanced nasopharyngeal carcinoma. Actuarial rates of survival and distant metastases were calculated. The followed electronic databases were searched the Chinese Biomedicine database,Pubmed,Medline,Embase and Cochrane library:Data were extracted by tow reviewers and Review manager 4.1 software was applied for statistical analysis. Results Eighteen trials with 1993 patients were include according to the including criterion. The 3-year overall survival rate of the chemoradiotherapy group and the radiotherapy group were 68.47% and 56.38% respectively, and the 5-year overall survival rate of the two groups above were 51.91% and 41.09% respectively, while the distant metastases rate of the chemoradiotherapy group and the radiotherapy group were 26.19% and 38.71% respectively. The result demonstrated that chemoradiotherapy increased overall survival by 12% at 3 years, and 11% at 5 years after treatment. After chemoradiotherapy,the rate of distant metastasis was reduce by 12%. Conclusions In patients with locoregionally advanced nasopharyngeal carcinoma,chemoradiotherapy significantly improves overall survival at 3 years,and 5 years compared with radiotherapy alone.
