Objective To investigate the correlation of hs-CRP and systemic immunoinflammatory index(SII)with the severity of coronary artery stenosis in elderly T2DM patients.Methods A retrospective trial was conducted on 158 elderly T2DM patients admitted to the Affiliated Hospi-tal of Xuzhou Medical University from August 2021 to August 2023.According to the results of coronary angiography,they were divided into mild(Gensini score≤60,79 cases)and severe steno-sis groups(＞60,79 cases).Spearman correlation analysis and logistic regression analysis were ap-plied to analyze the correlation and the risk factors for severe stenosis.Results Significantly high-er hs-CRP and SII were observed in the severe stenosis group than the mild stenosis group(P＜0.01).Hs-CRP,SII,glycosylated hemoglobin,neutrophils,hsTNT,NLR,and PLR were positively correlated with Gensini score(r=0.424,P＜0.01;r=0.367,P＜0.01;r=0.207,P＜0.01;r=0.259,P＜0.01;r=0.187,P＜0.05;r=0.317,P＜0.01;r=0.256,P＜0.01),and the course of T2DM was negatively correlated with Gensini score(r=-0.224,P＜0.01).Multivariate logistic regression showed that hs-CRP and SII were independent risk factors for severity coronary artery stenosis in elderly T2DM patients(OR=3.191,95％CI:1.847-5.513,P=0.000;OR=1.006,95％CI:1.004-1.009,P=0.000).Conclusion Elderly T2DM patients have higher levels of hs-CRP and SII,which may be independent risk factors for the pathogenesis of coronary stenosis.

Objective:To explore the effect of manual prompts in the first detection of lung function and fractional exhaled nitric oxide (FeNO) in patients with airway inflammation of unknown origin.Methods:From May 2018 to December 2020, convenience sampling was used to select 810 patients with airway inflammation of unknown origin in the Department of Respiratory of the China-Japan Union Hospital of Jilin University as the subject. Subjects were divided into a observation group ( n=406) and a control group ( n=404) . This study compared the quality control parameters of lung function detection [forced expiratory time (PET) , backward extrapolated volume (VBE) , time from forced expiratory to peak flow rate (FET-PET) , percentage of backward extrapolated volume to forced vital capacity (VBE/FVC%) ] , reproducibility parameters [variation between optimal and suboptimal forced vital capacity (ΔFVC) , variation between optimal and suboptimal first second forced expiratory volume (ΔFEV 1) ] , and detection efficiency indicators (detection time for lung function and FeNO, one-time success rate of FeNO detection) between two groups. Results:The VBE/FVC%, ΔFVC, and ΔFEV 1 in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . The lung function and FeNO detection time of the observation group were shorter than those of the control group, and the one-time success rate of FeNO detection was higher than that of the control group, with statistical differences ( P<0.05) . Conclusions:In lung function and FeNO detection for the first time among patients with airway inflammation of unknown origin, manual prompts can improve the quality control and reproducibility of the detection, shorten the detection time, and increase the one-time success rate of FeNO detection.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Objective:To investigate the clinical and molecular features of patients with CD7 +relapsed or refractory acute myeloid leukemia(r/rAML)and the prognosis of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods:172 r/rAML patients who underwent allo-HSCT in department of hematology, Aerospace Center Hospital between January 1st 2017 and December 31st 2020 were retrospectively analyzed The patients were were divided into CD7 + group( n=75) and CD7 - group( n=97) according to the expression CD7 in the initial immunophenotype. Mann-Whitney U and Chi-square test were used to compare the clinical data, molecular and cytogenetic characteristics of the two groups of patients. Kaplan-Meier method was used to analyze the median progression-free survival (PFS) and median overall survival (OS) of the two groups of patients, and Cox regression screenthe prognostic factors of the patients. Results:The median follow-up time was 19 months. The recurrence rates were 23.71% and 50.67%, respectively in CD7 - and CD7 + group (χ 2=13.428 P<0.001). In relapsed patients, 86.96 percentage of CD7 - group did not express CD7 while 86.84 percentage of CD7 + group expressed CD7. The median PFS was 25 and 5 months in CD7 - and CD7 + group (χ 2=8.695, P=0.003), and the medianOS was 34 and 15 months in CD7 - and CD7 + group (χ 2=2.579, P=0.108). Univariate analysis showed that the CD7 +group, had the lower rates of morphological remission (χ 2=10.014, P=0.002), molecular remission (χ 2=22.809, P<0.001), and more male patients (χ 2=5.281, P=0.022). The incidence of CEBPA double-site mutation was higher (23.4% vs 8.2%, χ 2=8.180, P=0.004) and the rearrangement of RUNX1::RUNX1T1 was lower(4.0% vs18.6%, χ 2=8.362, P=0.004)in CD7 +group than in CD7 -group. Multivariate analysis showed that pre-transplant tumor load was the only prognostic factor for PFS (HR, 1.600; 95% CI, 1.203 to 2.127; P=0.001) and OS (HR, 1.737; 95% CI, 1.273 to 2.369; P<0.001) in r/r AML patients. Conclusion:CD7 expression is a risk factor for poor prognosis in r/r AML patients, and CD7 expression is stable after relapse. Positive CD7 can be used as a target for immune targeted therapy.

Objective: This cross-sectional study aimed to investigate the characteristics of malocclusions in scoliotic patients through clinical examinations. Methods: Fifty-eight patients with idiopathic scoliosis (IS) and 48 patients with congenital scoliosis (CS) participated in the study. A randomly selected group of 152 orthopedically healthy children served as the control group. Standardized orthodontic and orthopedic examination protocols were used to record the occlusal patterns and type of scoliosis. Assessments were made by three experienced orthodontists and a spinal surgery team. The differences in the frequency distribution of occlusal patterns were evaluated by the chi-squared test. Results: In comparison with patients showing IS, patients with CS showed a higher incidence of Cobb angle ≥ 45° (p = 0.020) and included a higher proportion of patients receiving surgical treatments (p < 0.001). The distribution of the Angle Class II subgroup was significantly higher in the IS (p < 0.001) and CS (p = 0.031) groups than in the control group. In comparison with the healthy controls, the CS and IS groups showed significantly higher (p < 0.05) frequencies of asymmetric molar and asymmetric canine relationships, upper and lower middle line deviations, anterior deep overbite, unilateral posterior crossbite, and canted occlusal plane, with the frequencies being especially higher in CS patients and to a lesser extent in IS patients. Conclusions Patients with scoliosis showed a high frequency of malocclusions, which were most obvious in patients with CS.

Objective:To explore the relationship between blocking antibody and lymphocyte subsets in elderly patients (age≥35 years old) with recurrent spontaneous abortion(RSA).Methods:A retrospective case-control study was conducted on the patients with recurrent spontaneous abortion who met the inclusion criteria from October 2014 to September 2019 in the Reproductive Center of Women Health Center of Shanxi.They were divided into two groups according to their ages: 66 cases in RSA group and 334 cases in normal pregnant age group.The blocking antibody and lymphocyte subsets were detected by flow cytometry.Results:The negative rate of blocking antibody in elderly recurrent spontaneous abortion patients was 77.27% (51/66), which was not significantly different from that in normal gestational recurrent spontaneous abortion patients (83.53%(279/334)) ( P=0.221), but significantly higher than that in normal women (23.46%(42/179)) ( P=0.001). The blocking antibody′s blocking efficiency results showed that the CD3′s blocking efficiency of elderly recurrent spontaneous abortion patients (0.10 (-0.50, 0.60)) was significantly lower than that of normal women (0.60 (0.00, 1.30)), the difference was statistically( P=0.001). The CD8 blocking efficiency of elderly recurrent spontaneous abortion patients (0.00 (-0.60, 0.63)) was significantly lower than that of normal women (0.30 (0.00, 0.70)), the difference was statistically( P=0.016). Lymphocyte subsets showed that the CD8 + T cell ratio in elderly recurrent spontaneous abortion patients (26.93±7.25) was significantly lower than that in normal gestational recurrent spontaneous abortion patients (29.22±7.29), the difference was statistically significant ( P=0.020). The CD4 + /CD8 + ratio in elderly recurrent spontaneous abortion patients (1.64±0.99) was significantly higher than that in normal gestational age recurrent spontaneous abortion patients (1.37±0.50), the difference was statistically significant ( P=0.030). The ratio of natural killer cells in elderly recurrent spontaneous abortion patients (16.13±7.10) was significantly higher than that in normal women (14.04±2.35), the difference was statistically significant ( P=0.022), and higher than that in normal gestational age recurrent spontaneous abortion women (15.57±7.02). Conclusion:There were differences in lymphocyte subsets between elderly RSA patients and normal pregnant women, and the increase of natural killer cell ratio may be an important factor in the occurrence of RSA, especially in elderly RSA patients.
