Objective:To investigate effects of dendritic cells(DCs) pulsed with autologous hepatoma cell lysates on the immune function of the postoperative patients with hepatocellular carcinoma(HCC).Methods:DCs isolated from peripheral blood mononuclear cell of HCC patients were cultured and proliferated in vitro by using rhGM-CSF and rhIL-4,and then were pulsed with autologous hepatoma cell lysates.30 postoperative patients with HCC were randomly divided into 2 groups.15 cases were treated with dendritic cell vaccine.15 cases received only chemotherapy and were established as control group.Immune function、clinical effects in two groups of patients were compared and observed.Results: The levels of DC3~+、DC4~+/CD8~+ and NK cell in the DC vaccine group significantly increased after vaccination,while those of the control group had no significant changes.The levels of IgG、IgM、IgA in the DC vaccine group increased after vaccination,but didn't reach statistical significance.The concentration of IL-10 in the DC vaccine group significantly decreased after vaccination(P

Nrf2/Keap1/ARE is an important signaling pathway in maintaining the balance between peroxide and antioxidants. Once oxidative stress happened, Nrf2/Keap1/ARE would be ac-tivated to regulate the expression of downstream antioxidant pro-teins that could reduce the injury from oxidative stress and the level of oxidative stress. Recent researches show that Nrf2/Keap1/ARE signaling pathway is closely related to refractory re-spiratory diseases such as pulmonary fibrosis (PF), lung canc-er, chronic obstructive pulmonary disease (COPD), suggesting that Nrf2/Keap1/ARE signaling pathway may be a potential ther-apeutic target. This review focuses on the role of Nrf2/Keap1/ARE signaling pathway in refractory respiratory diseases in order to further understand the related mechanism and provide evidence for the diagnosis and treatment of refractory respiratory diseases.

Purpose:To explore the in vitro effects of apoptosis induction of 2-methoxyestradiol(2ME2),an estrogen derivative on primary myeloma cells and hematopoietic precursors from multiple myeloma patients. Methods:The primary myeloma cells and hematopoietic precursors from 14 multiple myeloma patients were examined determine apoptosis cells in situ by terminal-deoxynucleotidyl transferase mediated dUTP nick end labeling(TUNEL)assay. Results:After co-cultured with different concentrations (1,4,16?mol/L) 2 ME2 for 48h respectively,apoptotic ratios of myeloma cells were 10.5? 1.2%,21.2?2.3%,36.8?3.6% respectively ,which shows a concentration- dependence.In comparision with the control group,the difference is of statistical significance(P0.05). Conclusions:2ME2 could electively induce apoptosis of primary myeloma cells from myeloma patients and has little apoptotic effect on granulocytic,erythrocytic and lymphocytic cells in the bone marrow.

In the course of the establishment of the basic medical insurance system, medical and health institutions at various levels are going to face the readjustment of functional orientation and transformation of the current pattern of medical setups will produce a far reaching effect on medical institutions. While “reducing burdens”, big hospitals must try actively to suit the needs of the medical market under the new circumstances, give full play to their strong points, such as high concentration of talents, knowledge and resources, and provide quality, high efficiency and high value added medical service. It must also be brought to peoples awareness that third tier hospitals are not just the supplement and extension of community medical service but should also serve as its guarantee and backing.

This paper presents a portable neurogenic bladder curer,which can produce a series of pulses according to human's physiology characteristic to stimulate bladder's points.Such bladder-related diseases can benefit from this curer as increased residual urine in the bladder,urine retention and urine incontinence.Being low-cost,small and portable,it can satisfy the needs of different patients.

Objectives: To study the apoptosis induced by homocysteine (Hcy) and the protective effects of folic acid, VE and Se. Methods: Inverted microscopy and MTT test were used to observe the protection of these nutrients on the cytotoxic effect of Hcy. DNA agarose gel electrophoresis and flow cytometry were used to observe the inhibition of these nutrients on the apoptosis induced by Hcy. The level of MDA, the activity of SOD and GSH-Px and the generation of active oxygen in cells were also measured to investigate the mechanism of the protective effects. Results: Significant effects of folic acid, VE and Se on the protection of cell damages and the inhibition of apoptosis induced by Hcy were observed. These protective effects may be the results of decreasing MDA in cells provided by folic acid, VE and Se, increasing the activity of SOD by folic acid, increasing the activity of GSH-Px by folic acid and Se, and decreasing the generation of active oxygen by VE. Conclusions: The protective effects of folic acid, VE and Se on the damage of ECV304 cell from Hcy and the inhibitive effect on apoptosis induced by Hcy might be in different mechanisms.

Objective To evaluate the quality of the randomized controlled trials (RCTs) published in two key Chineze journals on clinical nutrition.Methods The articles published in CHINESE JOURNAL OF CLIN-ICAL NUTRlTION and PARENTERAL & ENTERAL NUTRITION from 2000 to 2008 were reviewed and the RCTs were identified according to criteria of the handbook of Cochrane Collaboration.The Jadad scale was used to evalu-ate the quality of these RCTs.Results Totally 238 RCT articles were published in these two journals in this peri-od.The Jadad score of all RCT articles was 1.65±0.82.Twenty-eight articles (11.76%) were of high quality and only 5 articles (2.10%) were identified 5 points.There were some problems in the RCTs design,conduction and analyses included unclear randomization methods,poor comparison,lack of inclusion and exclusion criteria.less blinding employment,unclear withdrawals and dropouts,and improper sample size.Conclusion The design and quality control of Chinese clinical nutrition RCTs still have some problems and require further improvement.
