The purpose of this study was to explore the effect of proteasome inhibitor, bortezomib (Bzb), on osteoblast in pathologic status of myeloma bone disease. The myeloma bone disease was modeled by co-culture of mouse myeloma cell RPMI8226 with osteoblast line MC-3T3E1 from mouse calvaria, and intervenient culture of supernatant. The inhibitory effect of Bzb on proliferation of MC-3T3E1 assayed by modified MTT method, the apoptosis of MC-3T3E1 cells was determined by flow cytometry with Annexin V/PI staining, the expressions of osteoblast markers, Runx2/cbfa1, osteocalcin (OCN) and osterix (OSX) in MC-3T3E1 treated with Bzb were detected by RT-PCR and Western blot respectively. Experiments were divided into 3 group: single cultured, co-cultured and supernatant-interveniently cultured groups. The results showed the Bzb in higher concentration inhibited proliferation of MC-3T3E1 cells in a dose-dependent manner, with the IC(50) of 38.1 nmol/L for 48 hours, the Bzb in low concentration (5 nmol/L) did not show the inhibitory effect on proliferation of MC-3T3E1 in single cultured group (p>0.10), but could decrease apoptotic rate of MC-3T3E1 by 32.5% and 24.6% respectively in cocultured and supernatant-interveniently cultured groups, moreover increased the expression of osteoblast-related gene OSX, OCN mRNA and protein (p<0.05), while no obvious change of Runx2/cbfa1 expression was observed (p>0.05). It is concluded that the proteasome inhibitor, Bzb, in low concentration promotes the activity of osteoblast internal mechanisms, and prevents the apoptosis of osteoblasts induced by myeloma cells. In addition, it can up-regulate transcription and expression of osteoblast markers related to Runx2/cbfa1 path way, thus may protect osteoblasts in myeloma bone disease.

OBJECTIVETo study the role of aquaporin 5(AQP5) in regulating the cell proliferation and apoptosis of human colorectal cancer cells and explore the possible mechanism.

METHODSA small interfering RNA (siRNA) targeting AQP5 was used to suppress endogenous AQP5 expression in the human colorectal cancer cell lines COLO 205 and SW480, and the transfection efficiency of AQP5 siRNA was determined using immunofluorescence assay and PCR. The changes in the proliferation of the transfected cells was evaluated with MTT assay, and the cell apoptosis was analyzed using Annexin V-FITC/PI and TUNEL assays; the changes of Bax and Bcl2 expressions in the cells were determined using RTPCR and Western blotting.

RESULTSTransfection with AQP-5-siRNA resulted in a significant reduction (up to 90%) of AQP-5 expression in COLO 205 and SW480 cells. MTT assay showed that AQP-5-siRNA transfection significantly inhibited the cell proliferation compared NS siRNA transfection (P<0.05). Flow cytometric analysis revealed significantly increased apoptotic rate of cells following AQP-5-siRNA transfection compared with NS?siRNA transfection(P<0.05). Real-time quantitative RT-PCR and Western blotting demonstrated that AQP-5-siRNA transfection significantly increased Bax and Bcl-2 expressions at both mRNA and protein levels in the cells.

CONCLUSIONAQP5-siRNA can promote apoptosis of colorectal cancer cells in vitro possibly in relation to its effects on Bax and Bcl expressions.

Objective To investigate the expressions of the putative brain tumor stem cell (BTSC) marker CD133, nestin and proliferating cell nuclear antigen (PCNA) in formalin-fixed and paraffin-embedded gliomas, and discuss the BTSC microenvironment: the composition, morphology and distribution of the niche. Methods The samples of 74 patients performed resection of the glioma in our hospital from January 2007 and October 2008 were chosen. According to WHO 2008 classification of nervous system tumors, they were assigned into low-grade glioma group (grade Ⅱ, 22) and high-grade glioma group(grade Ⅲ, 27 and grade Ⅳ,25). Immunohistochemistry was used to detect the expression of CD 133 in 74 cases of brain gliomas. Double immunofluorescence staining was employed to detect the co-expressions of CD133/nestin or CD133/PCNA. The percentages of the CD133+cells, CD133+ blood vessels and CD 133+ niches were calculated, and correlation analysis was also performed on their percentage and the pathological grading of the tumor. Results Accumulated CD 133+ cells grew in the niches. CD 133+ niches could be observed in all grade gliomas; low-grade group showed lower level expression of the CD 133+ niches, fewer proliferating cells, clearer boundary between the 2 neighboring niches and fewer surrounding blood vessels as compared with high-grade group. Besides CD113+/nestin+ BTSCs, some subsets as CD133+/nestin-cells and CD133-/PCNA+ cells were noted in the niches in the high-grade group. The percentages of CD 133+ cells, CD 133+ blood vessels and CD 133+ niches were different in different grades of gliomas and the higher the grade of gliomas was, the higher their expressions were. Positive correlation was observed between the percentage of CD 133+ niches and the percentage of CD133+ blood vessels (r=0.425, P=0.000). The expression of CD133+ niches in high-grade glioma were higher than that in low-grade tumors (F=5.324, P=0.002). Conclusion Glioma tissues have niche structures, which composed of CD133+/nestin+ BTSCs and some subsets. CD133+ blood vessels were playing a key role in maintaining the niche structure, and the expression of CD133+ niches is statistically different in different pathological grading tumors.

BACKGROUNDPulmonary thromboembolism (PTE) has become a common disease that severely endangers people's health. This study analysed the changes in proportion and mortality of PTE in hospitalized patients to provide data for prevention and management of the disease.

METHODSThe data of 763 hospitalized patients with PTE from 1974 to 2005 in Fuwai Hospital were analysed.

RESULTSDuring the 1970s, 0.27% of patients in a cardiovascular hospital had PTE (< 5 cases per year); while so far this century the proportion is 0.94% (48 to 113 per year). The mortality of hospitalized PTE patients fell from 20.00% in the 1970s to 4.10% this century. Prior to 1990, the mortality of hospitalized PTE patients was 12.50%, and in the years after 1990 only 3.40%. The difference was statistically significant (P < 0.005). People with this disease were mostly between the ages of 30 and 69 years. Men were most susceptible between the ages of 30 and 69 years, while women between the ages of 40 and 69 years. Men contracted PTE 10 years earlier than women. The mortality of male PTE patients was 4.70%, not significantly different from female patients, 5.06% (0.50 < P < 0.75). There were not any significant differences between the mortality of patients in the different age groups overall (< or = 39, 40 - 49, 50 - 59, and > or = 60 years, P > 0.1). More people contracted the disease in winter than in other seasons (P < 0.05). There was no obvious difference between the mortality in different seasons overall (0.75 < P < 0.90).

CONCLUSIONPTE is an increasingly significant disease and deserves adequate attention.

OBJECTIVETo evaluate the overall efficacy and transplant-related mortality (TRM) of related and unrelated allogeneic peripheral blood hematopoietic stem cell transplantation (allo-PBSCT) in chronic myeloid leukemia (CML) patients conditioned with fludarabine-busulfan (FB) reduced intensity regimen.

METHODSForty-four patients received FB (Flud 30 mgxm(-2)xd(-1) x 5 d, BU 4 mgxkg(-1)xd(-1) x 3 d) conditioning followed by allo-PBSCT. Of them, 29 patients were transplanted with related donor and 15 unrelated donor (URD). All patients received mycophenolate mofetil (MMF), CsA and MTX for acute GVHD (aGVHD) prophylaxis. 5 mg/kg rabbit-antithymocyte globulin (ATG-Fresenius) was incorporated in 15 URD recipients.

RESULTSAll patients were successfully engrafted. The median times to ANC above 0.5 x 10(9)/L in related (RG) and unrelated groups (URG) were 13.7 (9 - 18) d and 13.6 (12 - 17) d, and PLT above 20 x 10(9)/L were 15.3 (9 - 20) d and 14.7 (10 - 26) d, respectively. Two patients in RG. 1 in URG developed graft rejection 5 - 8 months after transplantation. One of the two patients in RG received second transplantation and engrafted. The cumulative incidence of aGVHD and cGVHD were 13.8% (4/29) and 46.4% (13/28) in RG, and were 33.3% (5/15) and 57.1% (8/14) in URG respectively. Two patients in RG relapsed after transplantation, and obtained CR again after donor stem cell infusion (DSI). Median time of follow-up was 34.7 (2 - 73) months. Thirty-four patients were alive and 10 died. The main causes of death were IP, GVHD, graft rejection and infection. The 5-year overall survival (OS) probability was 77.0%, and the disease-free-survival (DFS) was 73.9%, of which, 79.0% and 74.1% were in RG, and 73.3% and 73.3% in URG, respectively.

CONCLUSIONSFludarabine-busulfan based reduced intensity conditioning for allo-PBSCT with either related or unrelated donors is a safe, less toxic and curative approach to CML.

ObjectiveTo investigate the effect of mucin 1 (MUC1) on the proliferation and apoptosis of nasopharyngeal carcinoma (NPC) and its regulatory mechanism. MethodsThe 60 NPC and paired para-cancer normal tissues were collected from October 2020 to July 2021 in Quanzhou First Hospital. The expression of MUC1 was measured by real-time quantitative PCR (qPCR) in the patients with PNC. The 5-8F and HNE1 cells were transfected with siRNA control (si-control) or siRNA targeting MUC1 (si-MUC1). Cell proliferation was analyzed by cell counting kit-8 and colony formation assay, and apoptosis was analyzed by flow cytometry analysis in the 5-8F and HNE1 cells. The qPCR and ELISA were executed to analyze the levels of TNF-α and IL-6. Western blot was performed to measure the expression of MUC1, NF-кB and apoptosis-related proteins (Bax and Bcl-2). ResultsThe expression of MUC1 was up-regulated in the NPC tissues, and NPC patients with the high MUC1 expression were inclined to EBV infection, growth and metastasis of NPC. Loss of MUC1 restrained malignant features, including the proliferation and apoptosis, downregulated the expression of p-IкB、p-P65 and Bcl-2 and upregulated the expression of Bax in the NPC cells. ConclusionDownregulation of MUC1 restrained biological characteristics of malignancy, including cell proliferation and apoptosis, by inactivating NF-κB signaling pathway in NPC.
