Objective:To investigate the therapeutic efficacy of autologous hematopoietic stem cell transplantation (auto-HSCT) for treatment of diffuse large B-cell lymphoma (DLBCL) and the factors affecting the prognosis.Methods:A retrospective case series study was conducted. The clinical data of 51 patients with DLBCL who underwent auto-HSCT in the First Affiliated Hospital of Xinjiang Medical University from March 2019 to January 2024 were retrospectively analyzed. Patients were divided into high-risk group (19 cases) and non-high-risk group (low-risk, low-moderate-risk and moderate-high-risk groups, 32 cases) based on different risk stratifications; patients were divided into the germinal center B-cell (GCB) group (29 cases) and non-GCB group (22 cases) based on different cellular origins; patients were divided into BEAM group (39 cases) and BeEAM group (12 cases) based on different conditioning regimens before auto-HSCT; patients were divided into auto-HSCT consolidation therapy group (41 cases) and auto-HSCT after relapsed/refractory group (10 cases) based on different transplantation timings. The Kaplan-Meier method was used for survival analysis and log-rank was used for subgroup comparison.Results:All 51 patients achieved the hematopoietic reconstitution with no transplantation-related death within 100 d. Before auto-HSCT, 39 cases achieved complete remission and 12 cases (23.5%) achieved partial remission. After auto-HSCT, all cases achieved complete remission. Follow-up was until May 31, 2024, and the median follow-up time [ M ( Q1, Q3)] of 51 DLBCL patients was 33 (8, 43) months. After 51 DLBCL patients receiving auto-HSCT, 7 patients relapsed and 6 cases died including 3 cases with relapse-related death and 3 cases with non relapse-related death. The 3-year progression-free survival (PFS) and overall survival (OS) rates were 78.5% (95% CI: 64.4%-92.6%) and 85.5% (95% CI: 73.2%-97.8%), respectively. The 3-year PFS rate was 94.7% (95% CI: 84.7%-104.7%) in the high-risk group, 82.2% (95% CI: 67.9%-96.5%) in the non-high-risk group, and the difference in the PFS was not statistically significant between the high-risk group and the non-high-risk group ( P = 0.158). The 3-year PFS rate was 80.1% (95% CI: 64.4%-95.8%) in the GCB group, 88.1% (95% CI: 72.3%-104.2%) in the non-GCB group, and the difference in PFS was not statistically significant between the 2 groups ( P = 0.803). The 3-year PFS rate was 84.9% (95% CI: 72.6%-97.2%) in BEAM group, 61.1% (95% CI: 25.0%-97.2%) in the BeEAM group, and the difference in PFS was not statistically significant between the 2 groups ( P = 0.106). The 3-year PFS rate was 85.4% (95% CI: 73.4%-97.4%) in the auto-HSCT consolidation therapy group, 64.3% (95% CI: 31.4%-96.4%) in the auto-HSCT after relapsed/refractory group, and the difference in PFS was not statistically significant between the 2 groups ( P = 0.171). Conclusions:auto-HSCT is an effective therapy method for DLBCL.

Objective To investigate the clinical efficacy of the traditional Chinese medicine(TCM)throat opening and brightening method in treating unilateral vocal cord paralysis(UVCP).Methods Sixty patients with UVCP were prospectively collected and randomly assigned to two groups:the Chinese herbal medicine group(trea-ted with Buyang Huanwu Decoction,n=30)and the throat opening and brightening method group(treated with TCM throat opening and brightening method,n=30).The clinical studies that had utilized injection laryngoplasty for the treatment of UVCP(historical control group).Evaluation indicators included the voice handicap index-10(VHI-10),GRBAS-G,objective acoustic measurements of voice(vocal intensity,F0,shimmer,jitter,HNR),and aerodynamic measurements(maximum phonation time,MPT).Results Before treatment,no significant differences were observed between the two groups in all the evaluation indicators(P＞0.05).Post-treatment,the throat open-ing and brightening method group demonstrated significant improvements in VHI-10,GRBAS-G,shimmer,jitter,HNR,and MPT compared to pre-treatment values(P＜0.01),and these improvements were superior to those in the Chinese herbal medicine group.Pre-treatment VHI-10,GRBAS-G,and shimmer scores in the throat opening and brightening method group were significantly higher than those in the historical literature group(P＜0.01).Af-ter treatment,no significant differences were noted in any assessed parameters between the two groups(P＞0.05).Conclusion The TCM throat opening and brightening method significantly enhances phonatory function and quality of life in patients with UVCP,showing comparable efficacy to injection laryngoplasty.

Objective To investigate the changes of serum levels of soluble scavenger receptor 163 (sCD163),angiopoietin-like protein 3 (ANGPTL3) before and after intravenous thrombolysis in patients with acute cerebral infarction (ACI) and their correlation with prognosis. Methods A total of 60 ACI patients accepted by Cangzhou Central Hospital from June 2021 to June 2022 were collected as the ACI group,and another 60 healthy individuals were regarded as the control group. According to the National Institutes of Health Stroke Scale (NIHSS) score after admission,60 patients were divided into mild group (n=10),moderate group (n=38) and severe group (n=12).According to the scores on the modified Rankin scale 90 days after thrombolysis,patients were separated into a good prognosis group (n=42) and a poor prognosis group (n=18). The serum levels of sCD163 and ANGPTL3 were detected using enzyme linked immunosorbent assay (ELISA),and receiver operating characteristic (ROC) curve was applied to analyze the predictive value of serum sCD163 and ANGPTL3 levels for the prognosis of ACI patients after intravenous thrombolysis therapy. Results Compared with the control group,the levels of serum sCD163 (687.55±86.43 ng/ml vs 411.07±58.24 ng/ml) and ANGPTL3 (60.28±10.55 mg/L vs 25.34±5.93 mg/L) in ACI group were significantly increased,and the differences were significant (t=20.549,22.363,all P<0.05). The levels of serum sCD163 (551.65±69.66 ng/ml,668.92±81.12 ng/ml,859.79±117.24 ng/ml) and ANGPTL3 (44.52±8.12 mg/L,58.67±10.37 mg/L,75.34±13.12 mg/L) in mild,moderate and severe groups were gradually increased,and the differences were significant (F=36.011,23.007,all P<0.05). Compared with the good prognosis group,the proportion of time from onset to thrombolysis≥ 3 h,the proportion of NIHSS score>10 at admission,and the serum sCD163 and ANGPTL3 levels before and after thrombolysis were significantly increased in the poor prognosis group,and the differences were statistically significant (t/x2=5.644,4.775,8.982,10.866,10.293,9.702,all P<0.05). ROC results showed that the area under the curves(95％ confidence intervals)[AUC(95％CI)]of serum sCD163 and ANGPTL3 level alone in predicting the prognosis of ACI patients were 0.830 (0.711～0.915) and 0.783 (0.658～0.879),and their sensitivity and specificity were 72.22％ and 85.71％,77.78％ and 85.71％,respectively. The AUC(95％CI)of combined prediction of serum sCD163 and ANGPTL3 in predicting the prognosis of ACI patients[0.950(0.861～0.990)]was obviously greater than the AUC predicted by sCD163 and ANGPTL3 alone (Z=2.378,2.109,P=0.017,0.035). Conclusion sCD163 and ANGPTL3 levels are elevated in the serum of ACI patients,and are related to their severity and prognosis.

Objective:To report the clinical manifestations, structural and functional imaging features of 3 patients with progressive supranuclear palsy with predominant cerebellar ataxia (PSP-C) assisted by florzolotau ( 18F) positron emission tomography (tau PET) imaging, and conduct a literature review, aiming to provide a basis for the diagnosis and treatment of this rare type of PSP. Methods:The clinical data, brain magnetic resonance imaging, 18F-fluorodeoxyglucose PET ( 18F-FDG PET) and tau PET head imaging features of 3 patients with PSP-C who were admitted to the Department of Neurology, Peking Union Medical College Hospital from January 2019 to December 2021 were summarized, and a systematic review of related case reports or series studies from China and abroad was conducted. Results:The age of onset of the 3 patients was 55-61 years, and the disease duration was 2-5 years at the time of diagnosis. All patients had an onset of instable walking and had repeated falls, and the duration between fall and disease onset was 0.5-3.0 years, with an average of 1.5 years. At the time of diagnosis, all patients showed gait ataxia with or without limb ataxia. The results of the brain magnetic resonance imaging showed that all patients had midbrain atrophy and midbrain-to-pons ratio<0.52. The tau PET results of all patients showed significant tau protein deposition in the midbrain and mild to moderate tau protein deposition in the cerebellum, and case 2 had concomitant mild tau protein deposition in the prefrontal lobe and decreased 18F-FDG PET metabolism in this region, supporting the diagnosis of PSP. Literature review showed that 24 patients with PSP complicated with cerebellar ataxia were reported, and 23 patients provided detailed clinical data. All patients had gait ataxia on physical examination and the clinical manifestations were consistent with those of this group. Conclusions:PSP-C is characterized by early gait ataxia and falls as the core manifestations. Structural imaging shows mesencephalic atrophy, and tau PET shows mesencephalic and cerebellar uptake. In the case of atypical PSP, head magnetic resonance imaging combined with tau PET imaging is helpful to further determine the diagnosis of PSP.
