Journal of Chongqing Medical University 2003;0(05):-
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
2.Evaluation of randomized controlled trials in the studies of clinical nutrition
Chinese Journal of Clinical Nutrition 2009;17(6):321-323
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.
3.Role of COX-2-independent targets of celecoxib and related compounds on cancer prevention and treatment
International Journal of Surgery 2009;36(8):541-544
We reviewed the role of COX-2 independent targets of celecoxib and related compounds in cancer prevention and treatment. Direct non-COX-2 targets of celecoxib might be protein-dependent kinase 1 (PDK-1),Ca+ ATPase and carbonic anhydrase (CA), and so on; all of which are inhibited by celecoxib and are the main components in various pathways. Inhibition of these proteins leads to the induction of apoptnsis, the inhibition of cell cycle progression, angiogenesis, and metastasis, which are the main mechanisms by which celecoxib exerts its anticarcinogenic activity.
4.Effect of the reform of the medical security system on hospitals and countermeasures
Chinese Journal of Hospital Administration 1996;0(05):-
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 peoples 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.
5.Effect of 2-methoxyestradiol on apoptosis of bone marrow cells of patients with multiple myeloma
China Oncology 2001;0(03):-
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.
8.Optimal immunohistochemical diagnostic index for supraclavicular lymph node metastasis in lung cancer
International Journal of Laboratory Medicine 2015;(1):5-7
Objective To explore the optimal immunohistochemical (IHC)diagnostic index for supraclavicular lymph node me-tastasis in lung cancer.Methods In the premise of conforming to the evidence-based medicine,the biopsy of lymph node in 135 pa-tients with supraclavicular lymph node metastasis was performed and 7 antibodies were selected to be detected.135 cases were di-vided into two classes:class A (110 cases)and B (25 cases).The class A included 14 cases of primary lesion inside the lung by the histological analysis,43 cases of primary lesion inside the lung by the cytological detection and 53.cases of primary lesion inside the lung by the radiographic analysis.The class B included 25 cases of lesion outside the lung by the histological analysis.The detecting antibodies included CK7,CK20,EMA,CEA,TTF-1,SPB and vimentin.Results The sensitivity and specificity of single antibody for deducing the primary lesion inside the lung were 90.0% and 56.0% for CK7,98.0% and 40.0% for CK20,90.9% and 4.0%for EMA,80.9% and 36.0% for CEA,62.7% and 100.0% for TTF-1,65.6% and 100.0% for SPB,and 60.9% and 60.0% for vimentin.The quadruple antibodies (CK7,CK20,TTF-1 and SPB)showed the highest sensitivity(85.0%)and highest specificity (100.0%),which made the relatively high detection rate (80.0%)of lung cancer in clinic.Conclusion Analyzing and researching the IMC results is of great significance to guide the surgical pathological practice based on the evidence-based medicine.

10.STUDY ON THE PROTECTIVE EFFECTS OF NUTRIENTS ON THE DAMAGE AND APOPTOSIS INDUCED BY HOMOCYSTEINE
Acta Nutrimenta Sinica 1956;0(03):-
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.
