BACKGROUND Advanced gastric cancer(AGC)remains a challenging malignancy with poor prognosis.The combination of oxaliplatin and trastuzumab has shown promising results in AGC treatment.This study aimed to investigate the effects of oxaliplatin and trastuzumab combination therapy on serum tumor markers and T lymphocyte subsets in patients with AGC and to explore their potential as predictive biomarkers for treatment response.AIM To investigate the impact of oxaliplatin and trastuzumab combination therapy on serum markers and T cell subsets in patients with AGC.METHODS This prospective study enrolled 60 patients with AGC.All patients received oxaliplatin(130 mg/m^(2),every 3 weeks)and trastuzumab(8 mg/kg loading dose,followed by 6 mg/kg every 3 weeks)for six cycles.Serum carcinoembryonic antigen(CEA),cancer antigen 19-9(CA19-9),and cancer antigen 72-4(CA72-4)were measured before and after treatment.T-lymphocyte subsets,including CD3+,CD4+,CD8+,and CD4+/CD8+ratios,were also evaluated.The clinical response was assessed using the Response Evaluation Criteria in Solid Tumors version 1.1.RESULTS After six cycles of treatment,the CEA,CA19-9,and CA72-4 serum levels significantly decreased compared to baseline levels(P<0.001).The percentages of CD3+and CD4+T lymphocytes increased significantly(P<0.05),whereas the percentage of CD8+T lymphocytes decreased(P<0.05).The CD4+/CD8+ratio also significantly increased after treatment(P<0.05).Patients with a higher decrease in serum tumor markers(≥50%reduction)and a higher increase in CD4+/CD8+ratio(≥1.5-fold)showed better clinical response rates(P<0.05).CONCLUSION Oxaliplatin and trastuzumab combination therapy effectively reduced serum tumor marker levels and modulated T lymphocyte subsets in patients with AGC.Combination therapy not only has a direct antitumor effect,but also enhances the immune response in patients with AGC.Serum tumor markers and T lymphocyte subsets may serve as potential predictive biomarkers for treatment response in patients with AGC receiving combination therapy. 展开更多

Objective:To study the effect of Helicobacter pylori infection on rheumatoid arthritis and T-lymphocyte subpopulations in patients with rheumatoid arthritis and to provide a new method for the treatment of rheumatoid arthritis by removing Helicobacter pylori from patients.Methods:60 patients with rheumatoid arthritis admitted to the hospital from May 2022 to May 2023 were selected for the study,and all patients underwent a 13-carbon urea breath test to detect gastric H.pylori and the test results showed that 20 cases were negative and 40 cases were positive.The 40 positive patients were divided into the treatment group(n=20)and non-treatment group(n=20)by random number table method and the treatment group was given anti-Helicobacter pylori treatment,and the non-treatment group was given maintenance rheumatoid basic treatment,comparing the anti-cyclic citrulline peptide(CCP),DS28 score,peripheral blood T-lymphocyte subsets(CD4^(+)T-lymphocytes,CD8^(+)T-lymphocytes,CD4^(+)/CD8^(+)ratio)before and after the treatment of patients by 13-carbon urea respiration test(pylori-negative group,20 patients)and those who were positive for the treatment of H pylori(pylori-positive group,40 patients).Besides,the correlation of peripheral blood T-lymphocyte subsets and disease activity between treatment and non-treatment groups in the pylori-positive group was identified together with the correlation of DS28 scores,TNF-αlevels,sedimentation and immunoglobulin,lymphocyte subsets in the pylori-positive treatment group and positive non-treatment group as well as the level of globulin,lymphocyte subsets,and peripheral blood lymphocytes before and after treatment.Results:Before treatment,CCP,DS28 score,CD8^(+)T lymphocyte level of the pylori-negative group were lower than that of the positive group,and CD4^(+)T lymphocyte and CD4^(+)/CD8^(+)ratio were higher than that of the positive group(P<0.05);after treatment,the indexes of the pylori-positive group improved,and there was no significant difference in the comparison of the indexes with those of the pylori-negative group(P>0.05);the positive treatment group had a DS28(3.19±1.02)points,positive non-treatment group DS28(5.36±1.85)points,non-treatment group DS28 score and CD4^(+)T lymphocytes,CD4^(+)/CD8^(+)negative correlation with CD8^(+)T lymphocytes showed a positive correlation(P<0.05);before the treatment,pylori-positive treatment group and non-treatment group DS28 scores,TNF-αlevels,peripheral blood T lymphocyte subpopulation levels were not significantly different(P>0.05);after treatment,DS28 score,TNF-αlevel,CD8^(+)T of the treatment group were lower than those of the non-treatment group,and CD4^(+)T lymphocytes and CD4^(+)/CD8^(+)ratio were higher than those of the non-treatment group(P<0.05).Conclusion:H.pylori affects the level of T lymphocyte subsets in patients with rheumatoid arthritis,and there is a certain correlation between the two.Removal of H.pylori can improve the level of T lymphocyte subsets,which is important for the treatment of patients with rheumatoid arthritis. 展开更多

Background:Colorectal cancer(CRC)is a common gastrointestinal malignancy.The T lymphocyte subsets are important in the develop-ment,invasion and metastasis of tumors,including CRC.Nevertheless,limited research has explored the relationship between T cell subpopu-lations and the clinical characteristics of CRC.This study compared the T lymphocyte subsets in patients with CRC and healthy individuals,and assessed the relationship between these values and clinical characteristics.Methods:Peripheral blood was collected from 100 patients with CRC and 54 healthy individuals.The numbers of CD3^(+)T,CD4^(+)T,and CD8^(+)T lymphocytes,NK cells,and the CD4^(+)T/CD8^(+)T ratio in peripheral blood were measured using flow cytometry,and were compared between CRC patients and healthy individuals.Spearman's correlation analysis was performed to investigate the relationship between the T lymphocyte subsets in patients diagnosed with CRC and the levels of carcinoembryonic antigen(CEA)and thymidine kinase 1(TK1).Receiver operating characteristic(ROC)curves were utilized to evaluate the potential utility of the T lymphocyte counts in predicting lymph node metastasis,vas-cular infiltration,and high Ki-67 expression.Results:The CRC patients had lower counts of CD3^(+)T,CD4^(+)T,and CD8^(+)T lymphocytes compared to the healthy population(P<0.05).However,no significant differences were observed in the CD4^(+)/CD8^(+)ratio or NK cells(P>0.05).Notably,the CD3^(+)T,CD4^(+)T,and CD8^(+)T lym-phocyte counts were higher in patients with stageⅠ-Ⅱdisease,no lymph node metastasis,no vascular invasion,and low Ki-67 expression than in those with stageⅢ,lymph node metastasis,vascular invasion,and high Ki-67 expression(P<0.05).There was a negative association be-tween the CD3^(+)T,CD4^(+)T,and CD8^(+)T lymphocyte counts and CEA and TK1 levels in patients with CRC.The ROC curves demonstrated that CD3^(+)T,CD4^(+)T,and CD8^(+)T lymphocyte counts had significant predictive value for lymph node metastasis,vascular infiltration,and high Ki-67 expression.Conclusions:The peripheral blood CD3^(+)T,CD4^(+)T,and CD8^(+)T lymphocyte counts are related to the clinical traits of patients with CRC and can predict the prognosis of the disease. 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
