OBJECTIVETo assess the relationship between fractional esterification rate of high density lipoprotein cholesterol (FER(HDL)) and coronary artery disease.

METHODSA total of 131 hospitalized patients underwent coronary angiography due to chest pain were included in the study and patients were divided into CAD group (n = 76) and non CAD group (n = 55) according to coronary angiogram. Clinical and laboratory data including biochemical laboratory, FER(HDL) and lipid subclasses were analyzed.

RESULTSThe FER(HDL) value of CAD group was significantly higher than that of the non CAD group (21.70 ± 8.73 vs. 18.65 ± 6.26, P < 0.05). There was an increased trend of FER(HDL) with numbers of diseased coronary arteries, significant difference was evidenced between non CAD group and 3-vessel group (18.65 ± 6.26 vs. 24.00 ± 9.22, P < 0.05). FER(HDL) was positively correlated with TG (r = 0.647, P < 0.001), LDLb-C(r = 0.441, P < 0.001) and negatively correlated with HDL-C (r = -0.708, P < 0.001) and HDL(2)-C (r = -0.748, P < 0.001).

CONCLUSIONOur data showed that the values of FER(HDL) were significantly increased in CAD patients and correlated with the severity of the CAD.

OBJECTIVETo explore the activation and proliferation of specific T cells induced by artificial antigen-presenting cells (aAPCs) simulated dendritic cells (DCs) and to observed the effect of these T cells on leukemic cell killing.

METHODSaAPCs were developed by coating a human leukocyte antigen-immunoglobulin fusion protein ( HLA-lg), which was connected each one of the four CML28 antigen epitopes (DLMSSTKGL, DLMSSTKGL, ALFCGVACA, VLTFALDSV), and CD28-specific antibody, to magnet-beads CML cell specific peptides (CML28) served as target peptides. Bone marrow (BM) or peripheral blood (PB) mononuclear cells (MNCs) were isolated from HLA-A2 healthy volunteers, and co-cultured with aAPCs. Specific T lymphocyte were detected by flow cytometry. The fresh acute leukemic cells were used as target cells. The specific T cells incubated with leukemic cells for 4 h at ratios of 5:1, 10:1, 20:1, 40:1, 80: 1, respectively. The effect of leukemic cells killing was detected by lactate dehydrogenase release test.

RESULTSThe average ratio of CML-28 specific T lymphocyte in control group was (2.2 +/- 0.4)% and in experimental groups (DLMSSTKGL, DLMSSTKGL, ALFCGVACA, VLTFALDSV) were (13.5 +/- 1.6)%, (15.2 +/- 1.5)%, (14.7 +/- 1.8)% and (34.3 +/- 3.5)%, respectively, being significantly higher than that in control group (P < 0.01). Induction efficiencies of acute leukemic cells killing were significantly enhanced by increase of effector cells. The cytotoxic activity of specific T lymphocyte in one experimental group (VLTFALDSV) was much higher than that in other three experimental group (P < 0.05).

CONCLUSIONThis "prime and expand" regimen should be an alternative method for large scale amplification of rare tumor-specific CTLs and aAPCs might be a useful tool for leukemia immunotherapy.

To investigate expression of plk-1 gene and PLK-1 protein in acute leukemia patients and its clinical significance, and to observe the distribution of PLk-1 protein in acute leukemin cells, the mononuclear cells were separated from the bone marrow or peripheral blood of acute leukemia patients, bone marrow benign proliferation individuals and normal individuals. The expression of plk-1 gene and PLK-1 protein in those cells were detected with RT-PCR and flow cytometry respectively, the distribution pattern of PLK-1 was observed by fluorescent inverted microscope. The result showed that the expressions of plk-1 gene and PLK-1 protein in mononuclear cells of acute leukemia patients were much higher than that of bone marrow benign proliferation individuals and normal individuals. Fluorescent inverted microscopy revealed that PLK-1 was highly concentrated in cytoplasm of acute leukemia cells during interphase of mitosis, and it was found that PLK-1 was mainly distributed between sister chromatid during the mitosis in mononuclear cells of acute leukemia patients, but the expressions of plk-1 gene and PLK-1 protein almost were not observed in cells of benign proliferative bone marrow and normal bone marrow. It is concluded that increased plk-1 gene and protein perhaps play an important role in abnormal proliferation of acute leukemia cells and correlate with the malignamcy of leukemia. plk-1 gene or PLK-1 protein may be considered as a new target of therapy, and one of useful indicators in evaluation of curative efficiency and prognosis.

OBJECTIVETo study the current situation and factors influencing the behavior of fruit and vegetable intake in adolescents, and to discuss health education strategy related to the behavior.

METHODS1677 students were selected from primary school and middle school in urban area of Hangzhou by a multistage sampling method. The behavior of fruit and vegetable intake was surveyed by questionnaires of the patient-centered assessment and counseling for exercise plus nutrition project (PACE+) for adolescent-scale of fruit and vegetable consumption, and analyzed by Transtheoretical Model on the servings of intake, the stage of change, process of change, decisional balance and the current status of self-efficacy.

RESULTSThe average intake of fruit and vegetable in adolescents was (3.21 +/- 1.50) servings per day ("one serving" means 100 g cooked vegetable or 100 g fruit). The behavior of consuming fruit and vegetable in most of the adolescents was in the contemplation stage, accounting for 36.91% (619/1677). The process of behavior change, decisional balance (Pros) and self-efficacy existed a positive correlation with the process of stage (r(process) = 0.38, r(decisional balance (Pros)) = 0.26, r(self-efficacy) = 0.33, t values were 16.78, 11.02 and 14.31, P < 0.05). The servings of fruit and vegetable intake existed a positive correlation with stage transition and self-efficacy (beta(stage transition) = 0.665, t = 35.07, P < 0.05; beta(self-efficacy) = 0.050, t = 2.63, P < 0.05), and existed a negative correlation with decisional balance (Cons) (beta(decisional balance (Cons)) = -0.051, t = -2.84, P < 0.05).

CONCLUSIONFruit and vegetable intake of these adolescents are under the recommended dietary intake. Along with behavior stage development and self-efficacy improvement, the intake of fruit and vegetable also increased correspondingly. Intervention strategies should aim at improving the awareness of adolescents on the health benefits of fruit and vegetable intake and promoting their confidence to reach the recommended servings.

This study was aimed to investigate the effect of artificial antigen-presenting cells (aAPCs) on inducing activation and proliferation of specific T-lymphocytes through stimulating biological function of dendritic cells with aAPCs in vitro. The specific antigen of chronic myeloid leukemia CML-28 was screened as objective antigen peptide by using magnetic microbeads as vector; the CML-28 epitope sequence (Vltfaldsv) was obtained by antigen epitope prediction software; this epitope was coupled with MHC molecule and used as first signal molecule, the B7-1 molecule was used as second signal molecule; these 2 molecules simultaneously were loaded onto surface of magnetic microbeads so as to contract aAPC complex. The bone marrow mononuclear cells were derived from HLA-A2(+) healthy bone marrow donors, CD8(+) T lymphocytes were screened and co-cultured with aAPC complex. During culture the 5, 6-carboxyfluorescein diacetate succinimidyl ester (CFSE) was added and proliferation of T-lymphocytes was detected by CPSE and proliferation level of specific T lymphocytes was detected by flow cytometry. The results showed that the proliferation level of CML-28 specific T lymphocytes obviously increased in experimental group, average level was 17.34 +/- 0.65%, while average level in control was 2.25 +/- 0.43%, there was significant difference between them (p < 0.01). It is concluded that the aAPC complex can mimic human APCs in vitro, and stimulate activation and proliferation of CD8(+) specific T lymphocytes.

OBJECTIVEThis study was designed to explore the optimal management option for cervical metastases in tongue squamous cell carcinoma (SCC) with clinically N0 neck in order to avoid excessive or inadequate treatment in clinical practice.

METHODSClinical data of 327 cases of tongue SCC with cN0 neck were retrospectively analyzed. Neck control rates affected by different pathoclinical parameters were compared. Prognosis analysis and death analysis were also performed.

RESULTSOverall 3-year survival was 69.7% (228/327), 3-year survival of neck recurrent group and non-recurrent group was 39.1% (25/64) and 77.2% (203/263), and 51.5% (51/99) of the death related to neck failure. Overall neck control rate was 80.4% (263/327); neck control rate of wait and watch group, level I neck dissection, level I + II neck dissection, supraomohyoid neck dissection, radical neck dissection, functional neck dissection, was 67.5% (27/40), 72.7% (24/33), 60.0% (15/25), 84.9% (45/55), 86.8% (131/151), 84.0% (21/25), respectively. Treatment modality and cervical lymph node involvement were independent factors for neck control.

CONCLUSIONSNeck control is a key for prognosis of tongue SCC with cN0 neck. Supraomohyoid neck dissection is the first choice in management of cervical metastases in tongue SCC with cN0 neck, during which the suspected involved lymph nodes should be sent for frozen section to determine whether comprehensive neck dissection required. Multimodal metastasis and/or capsular spread are the indications for postoperative irradiation.
