Objective To study the expression of SGK1 in T lymphocytes from pediatric asthma,and the effect of SGK1 on the differentiation of T cells,also to explore the function of SGK1 regulating the differen-tiation of T subset in pediatric asthma. Methods Twenty-eight children with asthma were recruited in Xi′an children′s hospital and divided into moderate group and severe group according to diagnostic guideline of asth-ma. The serum levels of IL-4,IL-13 and IL-17A were analyzed by ELISA. The CD4 +T cells from PBMC and na?ve T cells were selected using magnetic beads. Na?ve T cells were differentiated in vitro under cytokines. SGK1 expression were analyzed with Real-time PCR. The ability of Th2 and Th17 on secreting IL-4 and IL-17A were detected after SGK1 was inhibited by siRNA. In vivo,shRNA-SGK1 Na?ve T cells were transferred into the mice asthma models by intravenous injection. The airway inflammation were observed in shRNA-SGK1 Na?ve T models. Results Compared with healthy children,the serum levels of IL-4、IL-13 and IL-17A increased signifi-cantly in the children with asthma. Importantly,the levels of these three cytokines were much higher with the de-velopment of asthma. SGK1 were up-regulated remarkably in CD4 +T cells from the children with asthma and were positively correlated with IL-13 and IL-17A. Besides,SGK1 expression increased in the differentiated Th2 and Th17 in vitro,but had no change in the differentiated Th1. The levels of IL-4 and IL-17A associated with Th2 and Th17 decreased after SGK1 was inhibited by siRNA. Similarly,In vivo,the serum levels of IL-13 and IL-17A and airway inflammation were reduced in shRNA-SGK1 Na?ve T models. Conclusion The over-expres-sion of SGK1 in pediatric asthma enhances the asthma progress by promoting the differentiation of T subsets.

Objective To investigate the value of initial absolute lymphocyte counts (ALC) in predicting the prognosis of children with primary immune thrombocytopenia(ITP).Methods The initial clinical data of 214 children with incipient ITP were retrospectively analyzed and followed up for more than one year.Statistical analysis was made to find out the influence factors for the prognosis of patients with ITP in children to evaluate the predictive value of ALC on assessing the prognosis of ITP in children,and to analyze the association between ALC and outcomes and the clinical value of prognostic stratification.Results The remission rate of children with ITP was 71.5％ in 12 months.Multivariate unconditioned Logistic analysis showed that disease duration,the infection history,response to treatment and ALC were independent risk factors for chronic ITP(all P ＜ 0.05).Cutoff value of initial ALC was 3.005 × 109/L,sensitivity and specificity of value were 71.9％,83.6％.Three months and 12 months no remission rate of ITP in children between ALC ＞ 3.005 × 109/L and ≤ 3.005 × 109/L had statistical significant difference (24.2％ vs 64.9％,8.3％ vs 54.2％,x2 =42.13,P ＜0.001).There was no statistical difference in therapy efficacy between 2 groups(x2 =5.098,P ＞ 0.05).Remission rate between the ≤5 years old group and ＞ 5 years old group was statistical difference based on age stratification(x2 =22.371,22.177,all P ＜ 0.01).ITP in children were stratified into low risk group,intermediate risk group,high risk group based on the initial ALC and infection history,with remission rates in 3 month respectively 75.8％,54.1％,22.8％,respectively,and 91.6％,68.4％,31.6％ in 12 months,respectively;there were statistically significant differences (x2 =44.867,68.802,all P ＜ 0.001).Conclusions Initial ALC is an independent effecting factor in the prognosis of children with ITP.Initial ALC could be used for stratifying patients with the infection history before 6 weeks and supposed to be a predictive index for the prognosis of ITP in children.

Objective: To study the relationship between platelet activation and the degree of bleeding in patients with primary immune thrombocytopenia (ITP) . Methods: 43 patients with ITP were assessed based on ITP-BAT bleeding grading system. Platelet membrane glycoproteins (GP) Ⅰb, GPⅡb/Ⅲa and P-selectin expression were detected by flow cytometry analysis with and without adenosine diphosphate (ADP) stimulation. Association of platelet activation with platelet count, immature platelet fraction (IPF) , bleeding severity were evaluated. Results: GPⅡb/Ⅲa and P-selection expressions on unstimulated platelet in ITP patients were higher than those in healthy controls (65.69±10.73 vs 7.16±0.99, t=4.130, P<0.001; 15.43±1.41 vs 12.55±1.03, t=2.070, P=0.043, respectively) , and GPⅠb expression was lower than that in healthy controls (240.11±24.93 vs 295.11±22.15, t=2.417, P=0.020) . Comparatively to healthy individuals, following ADP stimulation, GPⅡb/Ⅲa expression in ITP patients increased (133.96±12.17 vs 39.67±4.99, t=5.256, P<0.001) , whereas GPⅠb and P-selection expressions decreased (37.09±3.94 vs 109.77±23.66, t=3.901, P<0.001; 149.06±19.14 vs 205.73±21.00, t=2.070, P=0.043, respectively) . ADP-stimulated GPⅠb, ADP-stimulated and unstimulated P-selection, proportion of GPⅠb, P-selection levels with/without ADP stimulation were significantly associated with platelet counts (P<0.05) . ADP-stimulated P-selection and proportion of P-selection levels with/without ADP stimulation were significantly associated with IPF (P<0.05) . There were significant differences in the expressions of unstimulated P-selection, ADP-stimulated P-selection, ADP-stimulated GPⅠb stratified by bleeding grades (P<0.05) . The ratios of P-selection, GPⅡb/Ⅲa and GPⅠb with/without ADP stimulation in ITP patients were significantly different among various bleeding grades (P<0.05) . Higher proportion of GPⅠb with/without ADP stimulation was associated with higher risk of bleeding (OR=3.05, P=0.011) . Lower proportion of GPⅡb/Ⅲa and P-selection with/without ADP was associated with higher risk of bleeding (OR=0.32, P=0.023; OR=0.04, P=0.006, respectively) . Conclusion Platelet activation index could accurately assess the degree of bleeding in patients with ITP, and also be used as the observation index and reference index for treatment.

Objective:To investigate the correlation between systemic immune inflammatory index (SII) and other metabolic indicators and diabetic epiretinal membranes (dERM).Methods:A retrospective case-control study. From March 2022 to July 2023, 81 patients (81 eyes) with dERM in Department of Ophthalmology, Affiliated Jinhua Hospital of Zhejiang University of Medicine School diagnosed by fundus screening were included in the study. A total of 81 patients (81 eyes) with diabetes who were matched in age, gender, and duration of diabetes and had no dERM or diabetic macular edema in both eyes during fundus screening were selected as the control group. All patients underwent optical coherence tomography (OCT) examination and laboratory tests for peripheral blood neutrophil, lymphocyte, platelet counts, serum albumin, blood lipids, uric acid, and glycosylated hemoglobin (HbA1c). SII was calculated. Random urine samples were collected for urinary albumin/creatinine ratio (ACR) testing. The OCT device's own analysis software obtained the macular volume coefficient, including central foveal thickness (CMT), macular volume, and average macular thickness. The macular volume coefficient, SII, serum albumin, blood lipids, uric acid, HbA1c, and ACR between the two groups were compared using paired t tests or Mann-Whitney U tests. Conditional logistic regression analysis was performed to evaluate the risk factors for dERM; Spearman correlation test was used to analyze the correlation between CMT, SII, ACR, disorganization of retinal inner layers (DRIL), intraretinal cyst (IRC), and hyper-reflective foci (HRF) in patients with dERM. Results:There were significant differences in CMT, macular volume, average macular thickness, SII, serum albumin, and ACR between the dERM group and the control group ( Z=-7.234, -6.306, -6.400, -3.063, -2.631, -3.868; P<0.05). Conditional logistics regression analysis showed that high SII [odds ratio (OR)= 3.919, 95% confidence interval ( CI) 1.591-9.654, P=0.003] and ACR ( OR=4.432, 95% CI 1.885-10.420, P=0.001) were risk factors for dERM. Spearman correlation analysis showed that HRF, IRC, DRIL were positively correlated with CMT ( Rs=0.234, 0.330, 0.248; P=0.036, 0.003, 0.026); HRF was positively correlated with SII and ACR ( Rs=0.233, 0.278; P=0.036, 0.012). Conclusion:Elevated SII and ACR are independent risk factors for the occurrence of dERM.

OBJECTIVETo deepen the understanding of clinical manifestations and treatment of patients with positive lupus anticoagulant (LAC).

METHODSThe clinical data of 2 patients were analyzed and related literature were reviewed.

RESULTSCase 1, a 31-year-old female, diagnosed as lupus anticoagulant positive, secondary to undifferentiated connective tissue disease, was presented with menorrhagia and thrombocytopenia. Anti-nuclear antibody (ANA) was positive 1:1000 (homogeneous type) with anti-double stranded DNA positive, and dRVVT LA1/LA2 was 3.4. Coagulation function was alleviated after treatment with glucocorticoid and total glucosides of paeony. Case 2, a 59-year-old female was presented with gingival bleeding, hematuria with the level of F II:C 13%. dRVVT LA1/LA2 was 2.0. Anti-nuclear antibody (ANA) was positive 1:1000 (type of cytoplasmic granule), anti-double stranded DNA was positive. The patient was diagnosed as hypoprothrombinemia-lupus anticoagulant syndrome (LAHS) and acquired coagulation factor deficiency. The signs of hemorrhage were alleviated after treatment with methylprednisolone 40 mg/day and cyclophosphamide, while the level of F II:C was below normal.

CONCLUSIONSymptoms of patients with positive LAC are variable. The diagnosis relies on history of disease and laboratory test. Currently, there is no standardized treatment. Cases of LAHS should be thoroughly investigated for any known causes and related disorder.

Objective To explore the changes of whole brain white matter ( WM) structural net-work topological property in patients with schizophrenia (SP) and the associations between WM networks to-pological efficiency and clinical variables in patients. Methods Deterministic tractography was used to con-struct the WM networks of 59 patients with SP ( patients group) and 41 age-, handedness-, and gender-matched healthy controls (HCs),and graph theoretical methods were applied to investigate abnormalities in the global and nodal properties of the WM network in these patients. Partial correlation analysis was used to analyze the relationship between global and nodal properties of the WM network and clinical variables in pa-tients with SP. Results Both the patients with SP and HCs showed small-world organization of the WM net-works. However,compared with HCs,the patients with SP exhibited significant abnormal global topology,in-cluding increased shortest path length ( t=7. 95, P=0. 0001) and decreased global efficiency ( 30. 83 ± 16. 08,8. 25±6. 13,t=-9. 81,P=0. 002),clustering coefficiency (0. 03±0. 01,0. 02±0. 01,t=-4. 48,P=0. 0003),the average clustering coefficiency (t=-8. 28,P=0. 002),the small-worldness (3. 92±0. 79,2. 79 ±0. 56,t=-7. 82,P=0. 001) of their WM structural networks(all P<0. 005,FDR corrected). Further,the patients with SP showed a reduction in nodal efficiency predominately in the cingulate gyrus ( t=-4. 11, P=0. 000),superior occipital gyrus ( t=-6. 05, P=0. 002), superior temporal gyrus ( t=-10. 46, P=0. 001),middle temporal gyrus (t=-10. 38,P=0. 000),thalamus (t=-6. 10,P=0. 000) and putamen ( t=-8. 38,P=0. 000) (P<0. 005,FDR corrected). Partial correlation results showed that there was no signifi-cant correlation between global topological properties,node efficiency and clinical symptoms in patients group (Eglob:r=-0. 14,P=0. 279;Eloc:r=-0. 06,P=0. 628;Lp:r=0. 28,P=0. 031;Cp:r=0. 27,P=0. 043;λ:r=-0. 18,P=0. 166;γ:r=-0. 29,P=0. 026;σ:r=0. 26,P=0. 048;nEglob:r=0. 36,P=0. 005;nEloc:r=0. 02,P=0. 901). Conclusions The patients with SP exhibit the abnormal of whole brain WM structural network topological property and the node efficiencies of cortico-striato-thalamo circuitry are significantly re-duced.

Objective:To observe the local reactions and efficacy of CD19 CAR-T therapy in recurrence/refractory B-cell non-Hodgkin's lymphoma (R/R NHL) patients with >7.5 cm lesions.Methods:32 R/R NHL patients with >7.5 cm lesions were enrolled and injected with CD19 CAR-T cells. Flow cytometry was used to detect and observe the amplification of CD19 CAR-T cells in vivo. Enzyme-linked immunosorbent assay (ELISA) was used to detect cytokines in peripheral blood of patients. The side effects of CD19 CAR-T cell therapy included systemic side effects and local reactions of tumor. The local side effects were observed by Ultrasound, Computed tomography and Magnetic resonance imaging. Treatment options included glucocorticoid, interleukin-6 antibody and drainage of exudate. Overall response rate (ORR) and overall survival rate (OS) were observed.Results:①Among the 32 patients, CR (40.63%) , PR (31.25%) and ORR (71.88%) were 13, 10 and 23, respectively. ②In all 23 patients received ORR, 13 patients had grade 1-2 CRS, while 10 patients had grade 3-4 CRS. All the 9 patients in the SD+PD group had grade 1-2 CRS ( P=0.030) . ③A total of 15 patients with tumor local reactions, included 9 patients with CR, 5 patients with PR and 1 patient with SD. The local reactions of the tumor included that the diameter of the superficial lesions increased with redness, swelling and heat pain. The deep lesions presented abdominal pain, abdominal distension, suffocation and local pain, and burning of the tumor. The deep lesions were enlarged or accompanied by local edema. The local exudative lesions were found in the abdominal cavity and pleural cavity. ④ Peak proportion of CD19 CAR-T cells in ORR group was higher than that of in SD+PD group[16.8% (5.3%-48.2%) vs 2.9% (1.5%-5.7%) , z=-4.297, P<0.001]. The peak proportion of CD19 CAR-T cells in ORR group with local reactions was higher than that of in patients without local reactions [22.2% (10.5%-48.2%) vs 12.6% (5.3%-21.6%) , z=-3.213, P=0.001]. The peak proportion of CD19 CAR-T cells in multiple lesion group was higher than that of in single lesion group [35.8% (1.5%-48.2%) vs 16.8% (10.5%-18.5%) , z=-2.023, P=0.040]. ⑤Occurrence of local reactions and tumor shrinkage time were both delayed compared with systemic side effects. ⑥In the ORR group, the OS of patients with tumor local reactions was longer than that of patients without tumor local reactions, but there was no difference in the two groups (75% vs 34.6%, P=0.169) . Conclusions:CD19 CAR-T cell therapy in R/R NHL patients with >7.5 cm lesions might cause tumor local reactions later than systemic side effects.Clinicaltrial::ChiCTR1800018059

OBJECTIVETo explore the clinical significance, reliability and responsiveness of ITPBAT bleeding grading system for patients with immune thrombocytopenia (ITP).

METHODSOne hundred and eighty-three patients with ITP were assessed by using of ITP-BAT bleeding grading system. Test-retest reliability, responsiveness of ITP-BAT bleeding grading system and association between bleeding grades and platelet counts, age, gender, disease stage were analyzed.

RESULTSBleeding degree of ITP patients and the platelet count were negatively correlated (r=- 0.744, P<0.01) and bleeding degree increased significantly with platelet counts below 20×10⁹/L (χ²=82.40，P<0.01). Mild bleeding rate in children was 68.5%, higher than that in adult(χ²=8.839，P<0.01), and severe bleeding rate in the elderly was 14.3%, higher than that in non-elderly(χ²=7.056，P<0.01). There were no significant differences in bleeding degree in patients with different gender and disease stage (χ²=4.922, P>0.05 and χ²=3.411, P>0.05). Bleeding grades before and after treatment had more significant difference(Z=-6.61, P<0.01). Scoring consistency of two doctors was 66.1% (κ=0.561), and scoring consistency of the same doctor was 94.7% (κ=0.874).

CONCLUSIONITP-BAT bleeding grading system in China has good validity and responsiveness, closely related to clinical indicators. It is sensitive to the variation of the hemorrhage in patients. ITP-BAT could be used as a reference index of the treatment, and also be used as an observation index of curative effect.
