Objective To investigate the dynamic expression and clinical significance of toll-like receptor 4(TLR4)/CD80 in patients before and early after renal transplantation. Methods Thirty-two patients who received renal transplantation were enrolled in his study. All of them were primary recipients, and the level of panal reactive antibody less than 1%. The expression of TLR4 and CD80 in CD14, positive monocyte of peripheral blood from atients on the 1st, 4th, 7th, 14th, 21st, 28th and 35 th days after transplantation were measured by three-color fluorescent taining flow cytometry. The pa-tients were divided into rejection roup(7 cases) and non-rejection group(25 cases) according to rejec-tion episode record within 2 weeks. Normal control group(10 cases) enrolled healthy adult volunteers. Diagnosis of acute rejection depended on clinical symptoms, lab test, color doppler onography and re-nal biopsy. Results Before ransplanstation, the ressions of TLR4 and CD80 were (8.03± 0.84)% and (0.85±0.31)% in rejection group, (6.14±0.85)% and (0.84±0.39)% in non-rejec-tion group, (6.37±0.56)% and (0.85±0.35)% in normal control group. The expression of TLR4 of rejection group was higher than those of non-rejection group and normal control group(P<0.01). The expressions of CD80 of 3 groups had no significant difference(P=0.995). After ransplanstation, the expressions of TLR4 and CD80 increased to (16.50±1.02)% and (7.82±1.66)% in rejection group, (11.60±0.98)% and (2.26±0.96)% in non-rejection group at the 4th day, and reached the peak levels at the 7th day: (36.40±4.86)% and (9.53±1.97)% in rejection group, (22.70± 3.45)% and (1.87±0.72)% in non-rejection group, then displayed downtrend, rejection group de-creased to (7.10±0.82)% and (0.87±0.57)% at the 35th day, non-rejection group decreased to (7.20±0.76)% and (0.81±0.37)% at the 21st day. Compared with non-rejection group, rejection group showed higher peak expression value of TLR4/CD80 (P<0.01) and longer lasting time. Con-clusions The high expression of TLR4 may increase the risk of acute rejection. The up-regulated TLR4/CD80 levels early after renal transplantation may ontribute to the happeness of acute rejection.

Objective:To investigate the effect of glycogen synthase kinase-3β inhibitor TWS119 on hunman γδT cells growth and phenotypic characteristics. Methods:Using γδT medium to cultivate human peripheral blood γδT cells in vitro. After co-cultured with different concentrations of glycogen synthase kinase-3β( GSK-3β) inhibitor 4, 6-disubstituted pyrrolopyrimidine ( TWS119 ) for indicated time,growth curve and Wnt/β-catenin activation of in each group were determined by CCK-8 and Western blot assays. The CD62L and CD45RA expression theγδT cells were detected using flow cytometry. Results:Wnt/β-catenin pathway ofγδT cells could activate by TWS119. In the first group,TWS119 could upregulate the expression of CD62L and CD45RA in dose dependent manner while inhibit the growth and ratio of γδT cells. In the second group,TWS119 could promote the growth and ratio of γδT cells with the increase in concentration from 0 μmol/L to 4. 0 μmol/L and decreased thereafter. Besides,TWS119 could promote the expression of CD62L in a dose-dependent and had no effect on the CD45RA. Conclusion: Human γδT cells isolated from peripheral blood treated with TWS119 gave rise to two subsets of CD45RA+CD62L+γδT cells and CD62L+γδT cells.

Objective:To investigate the correlation between stress hyperglycemia ratio (SHR) and poor outcome of successful recanalization after endovascular treatment in patients with acute ischemic stroke.Methods:From January 2019 to October 2022, patients with acute ischemic stroke received endovascular treatment and successful recanalization in the Second People’s Hospital of Lianyungang were included retrospectively. SHR was defined as the fasting blood sugar and glycosylated hemoglobin ratio. At 90 d after procedure, the outcome of patients was evaluated using the modified Rankin Scale score. 0-3 was defined as good outcome, and >3 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent risk factor for poor outcome. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of SHR for 90 d poor outcome in patients with successful recanalization after endovascular treatment.Results:A total of 159 patients were enrolled, including 98 males (61.6%), aged 69.8±8.9 years old. The baseline National Institutes of Health Stroke Scale (NIHSS) score was 12.6±4.3, and SHR was 1.17±0.46. One hundred and five patients (66.0%) had good outcome, while 54 (34.0%) had poor outcome. There were statistically significant differences in SHR, fasting blood glucose, glycosylated hemoglobin, baseline NIHSS score and the proportion of patients with poor collateral circulation and symptomatic intracranial hemorrhage between the poor outcome group and the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that SHR was an independent predictor of poor outcome (odds ratio 2.254, 95% confidence interval 1.136-4.278; P<0.001). The ROC curve analysis showed that the area under the curve of SHR for predicting poor outcome was 0.726 (95% confidence interval 0.648-0.804; P<0.001), which was higher than fasting blood glucose and glycosylated hemoglobin. The optimal cutoff value for SHR was 1.21, and the sensitivity and specificity for predicting poor outcomes were 66.23% and 75.82%, respectively. Conclusion:SHR is associated with the poor outcome of successful recanalization after endovascular treatment in patients with acute ischemic stroke and can be used as a potential predictor.
