Objective:To study the relationship of serum neurotransmitters with anxiety depression, T lymphocyte subsets and NK cells in patients with lung cancer chemotherapy.Methods: 56 cases of patients with advanced lung cancer who received chemotherapy in the First Affiliated Hospital of Chengdu Medical College between July 2013 and August 2016 were collected as observation group, and 50 healthy subjects who received physical examination in our hospital during the same period were selected as normal control group. Serum neurotransmitter, negative emotions and immune index levels were compared between the two groups of subjects. Pearson test was used to evaluate the relationship of serum neurotransmitter contents with negative emotions and immune index levels in patients with lung cancer chemotherapy. Results: Serum neurotransmitters DA, 5-HT and NE contents in observation group were lower than those in normal control group;SAS and SDS scores were higher than those of normal control group;peripheral blood CD4+T lymphocyte level, CD4+/CD8+ ratio and NK cell level were lower than those in normal control group while CD8+ T lymphocyte level was higher than that in normal control group. Pearson test showed that serum neurotransmitters DA, 5-HT and NE contents in patients with lung cancer chemotherapy were directly correlated with anxiety depression, T lymphocyte subset and NK cell levels.Conclusion: Serum neurotransmitter expression decrease in patients with lung cancer chemotherapy, and this is one of the important causes of anxiety depression and immune dysfunction in patients. 展开更多

Objective To investigate changes in T lymphocyte subsets and NK cells in patients with simple Graves’ disease(GD)and Graves’ disease combined with type 2 diabetes mellitus(GD/T2DM).Methods Fifteen cases of GD/T2DM were selected from our hospital from November 2001 to November 2004.Before and after therapy thyroid function,thyroglobulin antibody(TGA),thyroid microsomal antibody(TMA)and blood glucose level were measured,and T lymphocyte subsets(CD3,CD4,CD8,CD4/CD8)and NK cells(CD56)were measured by immunofluorescence double labeling monoclonal antibody and flow cytometry,respectively.At the same time,comparison was made with simple GD(15 cases),T2DM(15 cases)and healthy control(20 cases).Results Before therapy,CD4/CD8,CD4 and NK cells in GD/T2DM were less than normal,and there was no significant difference in comparison with simple GD(P<0.05).In T2DM group,only CD4/CD8 and CD4 were less than those of healthy controls(P<0.05).When thyroid function recovered after 1 to 3 months of methimazole treatment in both GD/T2DM and simple GD groups,various indexes recovered,which were more obvious in simple GD.Conclusion Immune hypofunction of GD may be the key to the immune abnormality of GD/T2DM,which is more significant than that of simple GD or T2DM.The recovery of thyroid function and immune abnormality is not consistent,and the recovery of GD is more significant than that of GD/T2DM. 展开更多

BACKGROUND: The patient with malignant tumor always show immunologic function drawback and ingravescent with tumor development, especially in the aspect of cell-mediated immunity. This study was undertaken to define the relationship between the immune function of local cells and cancer development by investigating the distribution of natural killer (NK) cells and T-lymphocyte subsets in peripheral blood, the cancer tissue and the tissue surrounding gallbladder carcinoma. METHODS: The numbers of CD4(+) and CD8(+) T-lymphocytes and NK cells were measured by flow cytometry in samples taken from gallbladder cancer tissue, the surrounding tissues and peripheral blood of 38 patients, and compared with the numbers in the peripheral blood and gallbladder tissue of 30 patients with cholecystitis as controls. RESULTS: The numbers of CD4(+) and CD8(+) T-cells and NK cells in gallbladder cancer tissues were significantly higher than those in the surrounding tissue and gallbladder with gallstone. However, the ratio of CD4(+)/CD8(+) was lower in the cancer tissue than that in the surrounding tissue and tissue from gallbladders with gallstones. The distribution of CD4(+) and CD8(+) T-cells and NK cells in mucous membrane of cholecystitis gallbladder and that in the tissue surrounding gallbladder cancer were significantly different. CONCLUSIONS: Disproportionate and imbalanced distribution of NK cells and subsets of T-lymphocytes occurs in the mucous membrane proper of gallbladder cancer and surrounding tissue. Although gallbladder cancer tissue has higher expressions of CD4(+), CD8(+) and NK cells, the immune function is low or in an inhibited state. In gallbladder cancer immunization therapy, local cellular immunological function should be enhanced and the protective barrier improved. 展开更多

Study Objective: To observe the effect of dexmedetomidine (DEX) on T-lymphocyte subsets and natural killer (NK) cells in the peripheral blood of perioperative patients with colorectal cancer. Design: A random double-blind control clinical study. Setting: A university hospital. Patients: Forty patients with colorectal cancer, ASA I-П. Interventions: All patients were randomly divided into a DEX group (n = 20) and a control group (n = 20). Before induction of anesthesia, epidural catheters were placed in the L1-L2 or T12-L1 intervertebral spaces. The DEX group received 1 μg/kg of DEX (200 μg/50 ml) intravenously for 15 min prior to the surgery, which was then infused at a rate of 0.5 μg/kg/h until 30 min before the end of the surgery. The control group received an intravenous infusion of saline (50 ml) instead of DEX during the same periods as the DEX group. All patients received routine anesthesia and postoperative analgesia. Measurements: Blood samples from all patients were collected at the following time points: before anesthesia (T0), 24 h after surgery (T1), 48 h after surgery (T2) and 72 h after surgery (T3). Changes in T-lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) and NK cells were determined by flow cytometry. Main Results: Compared with the control group, the percentages of CD3+ and CD4+ cells and the CD4+/CD8+ ratio in the DEX group increased significantly from T1 to T3 展开更多

Context: The functional activity of NK cells depends on the balance between the engagement of activating and inhibitory receptors on the cell surface with their ligands, which enables them to kill infected cells. Objectives: The aim of this study was to evaluate and compare expressions of selected activating and inhibitory receptors on stimulated NK cells in HIV-1 and HIV-2 infections. Methods: PBMCs were analysed for activating (NKp30, NKp44, NKp46) and inhibitory (CD158a, CD158b, p70) receptor expressions in 30 HIV-1, 30 HIV-2 and 30 HIV uninfected healthy control (HC) subjects by flow cytometry after stimulating with K562 cells. Results: There was an expression of other receptors following an already in vitro engagement of NK cells with K562 cells. Higher expression of the activating receptors, NKp44 (p = 0.029) and NKp46 (p = 0.032) on NK cells from HIV-2 compared to HIV-1 infected individuals but similar NKp30 expression (p = 0.980). The levels of expression of inhibitory receptor CD158a were similar between HIV-1 and HIV-2 infected subjects (p = 0.309) but there was significant up-regulation of inhibitory receptors p70 (p = 0.010) and CD158b (p = 0.05) in HIV-1 compared to HIV-2 subjects. Conclusion: Despite the in vitro engagement of NK cells with stimulating K562 cells, our data showed differential expressions of other selected activating and inhibitory receptors in HIV-1 and HIV-2 infected subjects. 展开更多

Objective:To investigate the changes of Mg^(2+) levels in serum and peripheral blood mononuclear cells(PBMCs)of patients with COVID-19 and its effects on the functions of CD8^(+)T lymphocytes and NK cells.Methods:A total of 165 COVID-19 patients hospitalized in Ezhou Central Hospital from January 20 to February 20,2020 were divided into mild/common group(98 cases)and severe/critical group(67 cases).At the same time,34 healthy persons were selected as the control group.Peripheral blood was collected and PBMCs were isolated,the level of Mg^(2+) in serum and PBMCs was detected.The subsets of CD8^(+)T lymphocytes and NK cell and the expression levels of their surface inhibitory molecular PD-1 and activator molecular NKG2D were detected by flow cytometry.The correlation between Mg^(2+) concentration and the expression levels of PD-1 and NKG2D was also analyzed.Results:Compared with the control group,the concentration of Mg^(2+) in serum and PBMCs,the counts of CD8^(+)T lymphocytes and NK cell in patients with mild/common and severe/critical groups were significantly reduced(P<0.05),while the expression level of surface inhibitory molecular PD-1 were significantly increased(P<0.05),while the expression level of the activation molecule NKG2D were significantly decreased(P<0.05).However,the changes of the above indicators in patients with severe/critical group were greater than those in the mild/common group(P<0.05).In addition,the Mg^(2+) concentration in COVID-19 patients was negatively correlated with the expression level of PD-1 on CD8^(+)T lymphocytes and NK cells(P<0.05),and positively correlated with the expression levels of NKG2D(P<0.05).Conclusion:The concentration of Mg^(2+) in the serum and PBMCs of COVID-19 patients is significantly reduced,which may cause the function of CD8^(+)T lymphocytes and NK cells to be inhibited. 展开更多
