Objective To investigate the clinical characteristics, therapeutic outcomes and prognostic factors of primary nodal peripheral T-cell lymphoma(PTCL). Methods Clinical records, therapy responses as well as prognostic factors of 19 PTCL patients were analyzed. Results The median age of the 19 patients was Ⅲ-Ⅳ, 84.2 % (16/19) with B symptoms, 84.2 % (16/19) with extranodal involvement, 57.9 % (11/19) with bone marrow involvement. After treatment, the complete remission (CR) rate was 36.8 % (7/19). The 2-year overall survival (OS) rate of all patients was 47.2 % and the 2-year progression free survival (PFS) rate was 25 %. The number of sites of extranodal involvement (EN)≥2, ECOG≥2, IPI>2 and elevated β2-MG were poor prognostic factors. Conclusion Primary nodal PTCL is a heterogeneous group of aggressive T-cell lymphoma with poor chemotherapy results. Multifactors indicate negative prognosis.

Objective To observe the curative effects and toxicity of low-dose bortezomib plus thalidomide and chemotherapy in treatment of multiple myeloma. Methods 35 patients with initial, refractory or relapsed MM received at least two cycles of treatment with bortezomib at 1.1 mg/m2 intravenously on days 0,3, 7, and 10, and by daily oral thalidomide escalated from 50mg to 150 mg and chemotherapy. The chemotherapy regimens included MP, VAD and AD regimen which was chosen according to the status of patients. Results After a median follow-up of 20 months, the overall response rate was 82.8 %, complete remission (CR)48.6 %, very good partial remission (VEPR) 17.1%, and partial remission 17.1%. The 3-year PFS and OS were 60.92 % and 72.41% separately. ORR and OS were same in initial and refractory or relapsed MM patients. Grade 3 or 4 adverse events including debility (3/35), nausing and vomiting (8/35), constipation (4/35), peripheral sensory neuropathy (3/35), neutropenia (10/35) and thrombocytopenia (12 %) were observed.Conclusion The regimen of low-dose bortezomib plus thalidomide and chemotherapy is a highly effective and safety regimen for MM patients. The maintenane therapy with thalidomide may prolong PFS.

Microvesicles (MVs) are the heterogeneous mixtures of vesicles. MVs released by leukemia cells constitute an important part of the leukemia microenvironment. MVs might act as important reservoirs of microRNAs (miRNAs). It is worth evaluating whether MVs possess some unique miRNA contents that are valuable in understanding the pathogenesis. In this study, we investigated the miRNA expression patterns of Nalm-6-derived MVs, Jurkat-derived MVs and normal cell-derived MVs using miRNA microarrays. The potential target genes regulated by differentially expressed miRNAs were also predicted and analyzed. Results demonstrated that 182 miRNAs and 166 miRNAs were differentially expressed in Nalm-6-MVs and Jurkat-MVs, respectively. Many oncogenes, tumor suppressors and signal pathway genes were targeted by these aberrantly expressed miRNAs, which might contribute to the development of B-ALL or T-ALL. Our findings expanded the potential diagnostic markers of ALL and provided useful information for ALL pathogenesis.

OBJECTIVETo study the effect of phenformin hydrochloride that may be illegally added in traditional Chinese medicine preparations on the pharmacokinetics of puerarin in rats.
METHODRats were randomly divided into the single pueraria group and the phenformin hydrochloride combined with pueraria group. After oral administration in the two groups, their bloods were sampled at different time points to determine the drug concentration of puerarin in rat blood and calculate pharmacokinetic parameters.
RESULTAfter oral administration with pueraria extracts and phenformin hydrochloride combined with pueraria extracts, the two groups showed main pharmacokinetic parameters as follows: Cmax were (2.39 +/- 1.01), (1.03 +/- 0.35) mg x L(-1), respectively; Tmax were (0.50 +/- 0.09), (1.5 +/- 0.5) h, respectively; Ke were (0.153 +/- 0.028), (0.172 +/- 0.042) h(-1), respectively; t(1/2) were (4.65 +/- 0.86), (4.20 +/- 0.81) h, respectively; AUC(0-t), were (5.73 +/- 2.60), (5.45 +/- 1.81) mg x h x L(-1), respectively; AUC(0-infinity) were (6.72 +/- 2.89), (6.26 +/- 1.88) mg x h x L(-1), respectively. Compared with the single puerarin group, the Cmax was significantly decreased (P < 0.05) and the Tmax was markedly longer (P < 0.01) than the hydrochloride combined with pueraria group.
CONCLUSIONPhenformin hydrochloride can slow down the absorption process of puerarin and change the pharmacokinetic process of puerarin to some extent.

This study was aimed to explore the effect of Periplaneta Americana against alcohol-induced liver injury in mice, in order to provide a theoretical basis for the industrial production of P. Americana. Kunming mice were randomly divided into six groups, which were the normal group, model group, positive group, high-, middle-, low-dose of P. Americana groups. Intragastric administration of Tiopronin Enteric-coated Tablets 100 mg·kg-1 was given to the positive group. Intragastric administrations of whole powder of medicine were given to the high-, middle-, low-dose groups with the dosage of 6.667, 3.333, 1.667 g·kg-1, respectively. The drugs were given daily for 10 con-secutive days. After 3h of the 10th day drug administration, intragastric administration of distilled water was given to the normal group, while 14mL·kg-1 of 56℃ Red Star Liquor was given to other groups. No food was given but water for 12h. Blood was collected from the orbit. The ALT, AST and GGT in blood serum of mice were measured. The liver was dissected and liver coefficient was calculated. Histopathological examination was given on liver tissues. The results showed that compared with the normal group, the level of ALT, AST in blood serum of the model group had obvious enhanced (P< 0.01), the level of GGT had obvious enhanced (P< 0.05). Compared with the model group, the level of GGT, AST of the high-, middle-dose group had obvious enhanced (P< 0.05), the level of ALT activity had obvious enhanced (P< 0.01). There were severe liver histopathological damages in mice of the high-, middle-, low-dose group. It was concluded that P. Americana had some side effects in the treatment of alcohol-induced liver injury.

Objective To investigate the correlation of pretreatment serum squamous cell carcinoma antigen(SCCAg)with the clinico-pathological features of squamous cell carcinoma of uterine cervix and its significance as a prognostic factor.Methods One hundred and fourteen patients of squamous cell carcinoma of the uterine cervix(Ⅰbl-Ⅱa),who underwent pretreatment serum SCCAg evaluation and long-term follow-up after treatment were selected for this study.Clinical data were used to investigate the correlation between SCCAg and clinico-pathological features and factors that influence prognosis through univariate and multivariate analysis.Results Univariate analysis showed elevation of SCCAg(using≤1.5 mg/L as the cut-off value)was correlated with tumor size,deep stromal invasion and pelvic node metastasis (P0.05).However,between no pelvic node metastasis+elevated SCCAg cases and no pelvic node metastasis+normal SCCAg cases,there was a significant difference in DFS (71.8% vs 98.0%,P=0.003),recurrence rate(33.3% vs 9.8%,P=0.006)and local recurrence (26.5% vs 2.1%,P=0.001).Conelusions The independent prognostic factors for Ⅰ bl-Ⅱa squamous cell carcinoma of uterine cervix include elevated pretreatment SCCAg and pelvic node metastasis. Patients with elevated pretreatment serum SCCAg and no metastasis to pelvic lymph node(s)are at significantly elevated risk of local recurrence,and therefore need individualized treatment to improve local control and long-term survival.

Objective To evaluate the diagnostic value of the aldosterone-renin ratio (ARR) for primary aldosteronism (PA). Methods Serum aldosteronos ( ALD ) and plasma renin activities (PRA)among 44 subjects with primary aldosteronism, 9 subjects with phecchromocytoma, 8 subjects with nonfunctional adrenal tumors, 12 subjects with Cushing syndrome, 4 subjects with stenosis of renal artery and 13 subjects with primary hypertension were retrospectively reviewed. ARR was calculated. The receiver operating characteristics (ROC) curves for every index were used to evaluate diagnostic value. Results The area under the curve(AUC) in the ROC curve of ALD in a supine position was 0. 947, the cut-off value of diagnosis of PA. The AUC for the ROC curve of ALD in upright position was 0. 889, the cut-off value of ALD diagnosis of PA. The AUC for the ROC curve of ARR in a supine position was 0. 978, the cut-off value of diagnosis of PA. The AUC for the ROC curve of ARR in upright position was 0. 981, the cut-off value of specificity. If ARR was combined with ALD in upright position was used, the diagnostic value was better than either index. When ALD > 275 ng/L and the AUC for the ROC curve in upright position was 0. 989,specificity. Conclusions The diagnostic value of ARR in diagnosis of primary aldosteronism is higher than ALD and PRA. ARR in upright position is better than that in supine position, especially when combined with ALD > 275 ng/L in upright position.
