Akebia trifoliate has been reported to have many pharmacological activities and the roots, petioles and seeds are used to different symptoms. However, the structure and anatomy of its seeds was almost not reported until now. In the present study, we investigated the morphological characters of the fruit and seed, and the anatomical characters of the testa, micropyle, embryo and endosperm, which could provide evidences for the study on classification, identification and application of A. trifoliate. Our results showed that the testa of A. trifoliate consisted of an epidermic cell layer, the sclerenchyma cells layer, the parenchyma cells layer and an innermost pigment layer. At the micropylar region, the outermost epidermal cells were specialized the white caruncle-like structure and the testa included a lot of lignified tissues. Endosperm comprises two layer cells. Outermost yellowish-brown layer cells contains lots of fat droplets, and innermost white layer cells contains lots of aleurone grains and crystalloids.

OBJECTIVE:
To investigate the clinical features,therapy and prognosis of patients with peripheral T cell lymphoma(PTCL), and to find out the prognostic factors of the disease.
METHODS:
The clinical data of 73 patients with PTCL were reviewed.The median pre-treatment disease course was 3 months.Fifty-five patients were males, and 18 were females, with the median age of 42 years.Five patients received the combined chemo-radio therapy, 65 received chemotherapy alone, and the other 3 patients were treated with auto hematopoietic stem cell transplantation (HSCT).
RESULTS:
Of all the patients, the overall 3 -year and 5-year survival rates were 38% (28 /73) and 22% ( 16 /73) respectively.The survival rates decreased with the progression of the Ann Arbor stages.The survival rate of the patients with B symptom (fever, night sweat, and weight loss) or the international prognostic factors index ( IPI)>2 was lower than those of the patients without B symptom or IPI<2.The patients with the increased CA125 or D-dimer lever had the worst curative effect.
CONCLUSION
Peripheral T cell lymphoma is highly aggressive with poor prognosis.The clinical features,Ann Arbor staging, IPI and B symptom are important prognostic factors.CA125 and D-dimer may be also important prognostic factors.

To evaluate the therapeutic effect of hematopoietic stem cell transplantation (HSCT), we performed HSCT in 30 patients with hematologic maligancies. Of the 30 patients, 10 underwent autologous peripheral blood stem cell transplantation (auto-PBSCT), 13 underwent myeloablative allogeneic HSCT while 7 underwent nonmyeloablative allogeneic HSCT, which were designated as autologous group, myeloablative group and nonmyeloablative group, respectively. All patients except the one who underwent cord blood transplantation, were successfully engrafted. Median time for the granulocytes > or = 0.5 x 10(9)/L and platelets > or = 20 x 10(9)/L were 12 days and 13 days respectively in autologous group, 16 days and 19 days in myeloablative group, 15 days and 12 days in nonmyeloablative group. In myeloablative group, acute graft-versus-host diseases (aGVHD) was observed in 3 patients, all of which were I-II grade. Oral mucous cGVHD was observed in 1 patient. In nonmyeloablative group, 1 patient developed intestinal aGVHD grade IV and cutaneous cGVHD was induced by donor lymphocyte infusions (DLI) in 3 patients. 1 patient had hematological relapse in autologous group. 1 patient had cytogenetic relapse in myeloablative group. In nonmyeloablative group 3 patients had cytogenetic relapse and were cured by DLI, 1 patient had hematological relapse. 4 of the 30 patients died of infection (2 patients), grade IV aGVHD (1) and relapse (1) respectively. 26 patients are still alive. 3 years overall survival (OS) and 3 years disease free survival (DFS) were 100% and 64.81% respectively in autologous group, 78.75% and 63% respectively in myeloablative group while both 66.67% in nonmyeloablative group. In conclusion, autologous group had less transplant-related complications and mortality. Active prophylaxis of relapse could significantly promote DFS. The transplant-related mortality limited DFS in myeloablative group. More relapses occurred in nonmyeloablative group, but could be cured by DLI.

Background: Biotherapy based on human bone marrow?derived mesenchymal stem cells (BMSCs) is currently the focus of research, especially in the field of autologous stem cell transplantation. A novel type of metastasis?associated magnetic resonance (MR) molecular imaging probe was constructed, and the changes in metastasis and proliferation of hepatocellular carcinoma (HCC) before and after BMSC intervention were observed through MR imaging (MRI). Methods:Metastasis?associatedMRmolecularimagingprobe,integrin αvβ3 ligandcRGD?PEG?DGL?DTPA?Gd (Gd?RGD),wereconstructed. After human BMSC intervention was performed for 6weeks, tumor weight inhibition rates were calculated, and the RGD molecular probe was imaged through MRI with molecular imaging agent Gd?DTPAas control.The signal?to?noise ratio (SNR) and contrast?to?noise ratio (CNR) in the MRI experiment were used as semi?quantitative indicators. Polymerase chain reaction method was performed to detect proliferation? and metastasis?associated indicators, transforming growth factor β?1 (TGFβ1), osteopontin (OPN), and integrin subunit αv and β3. Results: The highest tumor weight inhibition rates were observed 3 weeks after the BMSC transplantation. The MR Gd?RGD in the HCC tissues after the BMSC intervention showed less enhancement than Gd?DTPA. The Gd?DTPAMRI of control group had higher SNR and CNR than Gd?RGD MRI in the experimental groups (P < 0.05). For high metastatic potential hepatocellular carcinoma (MHCC97?H), significant differenceswereobservedintheSNRsandCNRsofGd?RGDMRIbeforeandaftertheBMSCintervention(P<0.05).Forlowmetastaticpotential hepatocellular carcinoma (MHCC97?L), the CNRs of Gd?RGD MRI were statistically different before and after BMSC intervention (P < 0.05). With regard to MHCC97?H, OPN, β3, and TGFβ1 expression significantly decreased after BMSC intervention (P < 0.05). In MHCC97?L and OPN, β3, TGFβ1, and αv expression after BMSC intervention decreased, and the difference was statistically significant (P < 0.05). Conclusions: The CNR index of MRI is a good indicator for distinguishing high? and low?metastatic potential HCC tissues.After BMSC transplantation of MRI through the two kinds of tracer, the SNR and CNR indexes can distinguish two kinds of high and low metastatic potential HCC tissues, and Gd?RGD imaging is more suitable in distinguishing the metastatic potential changes through BMSC intervention.

The aim of this study was to clarify whether bortezomib might induce apoptosis in Burkitt's lymphoma Raji cell line and its mechanism. Different concentrations of bortezomib were used to treat Raji cells and its effects of time and dose were observed. Cell morphology was observed under light microscope; flow cytometry was used to analyze cell apoptosis; RT-PCR was used to detect the expressions of NF-kappaB and p53 gene mRNAs. The results showed that the bortezomib could inhibit Raji cell growth within a certain range of treating time and dose. Apoptosis were induced in relation to time and dose. The expression of NF-kappaB mRNA and p53 mRNA decreased after treatment with bortezomib. It is concluded that the bortezomib can induce Raji cell apoptosis, which provides a theoretical basis for clinical treatment. NF-kappaB and p53 gene are supposed to participate in the bortezomib induced apoptosis of Raji cells.

Objective To investigate the expression of CD27-CD70 co-stimulatory pathway in peripheral circulation and intestinal mucosa of patients with inflammatory bowel disease, and to find the difference between the expression of CD27-CD70 in patients with inflammatory bowel disease and in healthy controls. Methods A total of 62 patients with Crohn's disease, 64 patients with ulcerative colitis and 56 healthy controls were enrolled. Enzyme-linked immunosorbent assay was applied to evaluate plasma CD27-CD70 protein expression in patients with inflammatory bowel disease and healthy controls. SYBR-green real time PCR was applied to access CD27-CD70 mRNA expression in peripheral blood mononuclear cells in patients with inflammatory bowel disease and healthy controls.And CD27-CD70 protein expression in intestinal mucosa was determined by immunohitochemistry.Results Plasma levels of CD27 (P=0. 025) and CD70 (P=0. 000) were significantly higher in patients with Crohn's disease than in healthy controls. However, CD27 (r= 0. 055, P= 0. 673) and CD70 (r= 0. 024, P = 0. 852) were not significantly associated with endoscopic disease activity in patients with Crohn's disease. Similarly, CD27 (P=0. 001) and CD70 (P=0. 000) were significantly higher in patients with ulcerative colitis than in healthy controls. And CD27 (r=0. 077, P=0. 547)and CDT0 (r=0.021, P=0. 869) were not significantly associated with endoscopic disease activity in patients with ulcerative colitis. Moreover, CD27 and CD70 mRNA expression in peripheral blood mononuclear cells were significantly higher in patients with Crohn's disease and ulcerative colitis than in healthy controls (all P=0. 000), and immunostaining indicated that CD27 and CD70 expression in intestinal mucosa were significantly higher in patients with Crohn's disease and ulcerative colitis than in healthy controls (all P=0. 000). Conclusions CD27-CD70 pathway activated in plasma, peripheral blood mononuclear cells and intestinal mucosa of patients with inflammatory bowel disease. However,plasma levels of CD27 and CD70 can not reflect endoscopic disease activity.

BACKGROUNDVon Hippel-Lindau (VHL) disease is a heraditary cancer syndrome caused by germline mutations of the VHL tumor on the suppressor gene. This study was to show the clinical characteristics of a large Chinese kindred with von Hippel-Lindau disease and to evaluate the role of the genetic test of VHL disease in the diagnosis of VHL disease and clinical screening of members of the VHL disease family.
METHODSDNA extracted from peripheral blood was amplified by PCR to three exons of the VHL gene in 27 members of a large kindred with VHL disease. PCR products were directly sequenced. The involvements of multi-organs in the kindred with VHL disease were confirmed by history taking and radiography.
RESULTSOf 47 members in the four generations of the kindred, 18 members were diagnosed as having VHL disease. Clinical manifestations of 18 patients included: central nervous system (CNS) hemangioblastoma (5), renal cell carcinoma and CNS hemangioblastoma (3), renal cell carcinoma and retinal angioma (3), renal cell carcinoma and multiple pancreatic cysts (1), renal cell carcinoma and retinal angioma and multiple pancreatic cysts (2), renal cell carcinoma and CNS hemangioblastomas and multiple pancreatic cysts (1), and multiple pancreatic cysts and multiple renal cysts (1), multiple pancreatic cysts (2). The common lesions of the 18 patients were renal cell carcinoma (55.6%), CNS hemangioblastoma (50.0%), retinal angioma (27.8%), and multiple pancreatic cysts (38.9%). Among the 27 members who volunteered for genetic analysis, 15 members including 9 affected family patients and 2 asymptomatic patients and 4 carriers, who are still alive, presented a codon 78 from Asn to Ser change at nucleotide 446 (A-->G) in exon 1. Four members were carriers with the same VHL gene mutation. Two asymptomatic patients were initially diagnosed by genetic testing and subsequently confirmed radiologically and surgically. Members without gene mutation had no clinical evidence of VHL disease.
CONCLUSIONSThe large Chinese kindred with VHL disease was classified as type I. The main characteristics in the kindred were higher incidence of renal cell carcinoma and lower incidence of retinal angioma. Genetic test plays an important role in early detecting asymptomatic patients and the carriers in clinical screening of members of the families with VHL disease. It is also important to prevent the transmission of VHL disease to their offsprings in the kindred.
