Objective: To evaluate the effectiveness of "Internet plus" continuous intervention on psychological status and nursing satisfaction of patients with depression after hospital discharge, so as to provide the reference for reducing the recurrence risk of patients with depression and improving the quality of life. Methods: From January to December 2024, patients with mild to moderate depression who were hospitalized in a tertiary grade-a mental health specialized hospital in Wenzhou City and met the discharge criteria were selected as the research objects. The patients were divided into the control group and the intervention group according to a ratio of 1∶1 by the random number table method. Hamilton Depression Scale, Hamilton Anxiety Scale, and Nursing Satisfaction Questionnaire were used to evaluate depressive symptoms, anxiety symptoms, and nursing satisfaction before and after intervention. Covariance analysis was used to compare the differences between the two groups before and after the intervention. Results: A total of 62 patients with mild to moderate depression were enrolled, with 31 patients in the intervention group and 31 patients in the control group. Before the intervention, there were no statistically significant differences in gender, age, course of disease, educational level, marital status, depression symptoms score, anxiety symptoms score, and nursing satisfaction score between the two groups (all P>0.05). After the intervention, the scores of depression and anxiety symptoms in the intervention group decreased by 8.87 and 5.01 points, respectively, compared with those before the intervention, and the scores of depression and anxiety symptoms in the control group decreased by 2.52 and 1.16 points, respectively (all P<0.05). After the intervention, the scores of depression and anxiety symptoms in the intervention group decreased more than those in the control group (both P<0.05). The nursing satisfaction score of the intervention group increased by 6.57 points on average compared with that before the intervention, and that of the control group increased by 4.23 points on average (both P<0.05). There was no statistically significant difference in the increase of nursing satisfaction scores between the two groups before and after intervention (P>0.05). Conclusion The "Internet plus" continuous intervention has a good effect on improving the depressive symptoms and anxiety symptoms of patients with depression after haspital discharge, which can consolidate the treatment effect and improve nursing satisfaction.

Objective:To investigate effective strategies to reduce the high risk of recurrence after allogeneic hematopoietic stem cell transplantation(allo-HSCT)in patients with minimal residual disease(MRD)-positive B-lineage acute lymphoblastic leukemia(B-ALL).Methods:A retrospective analysis was performed for ten B-ALL patients with positive MRD before transplantation at our center from November 2022 to November 2024.There were four male patients and six female patients,with a median age of 30(7-56)years.Of all patients,four received transplantation from unrelated donors,and six received haploidentical transplantation from relatives.All ten patients received blinatumomab(28 μg/day for 14 days for patients≥45 kg;5 μg/m2/day for 14 days for patients<45 kg)and were bridged to the conditioning regimen for allo-HSCT within 7 days.Results:After treatment with blinatumomab,all ten patients achieved the clearance of MRD.After allo-HSCT,100%of the patients achieved donor hematopoietic reconstitution.The median time to neutrophil reconstitution was 12(9-22)days,and the median time to platelet reconstitution was 13.5(9-22)days.As of January 2025,the median observation time was 14(2-26)months;of all patients,two experienced recurrence,and one had positive MRD again,with a recurrence rate of 20%.Among the ten patients,nine survived and one died of disease recurrence.One patient achieved complete re-mission again after chimeric antigen receptor T-cell(CAR-T)therapy following recurrence,and the patient with positive MRD achieved the clearance of MRD again after interleukin-2 treatment;both patients were currently alive.During treatment,one patient developed cytokine release syndrome,one patient was comorbid with SARS-CoV-2 infection,one patient had herpes zoster and viral encephalitis,three patients developed grade Ⅰ-Ⅱ acute graft-versus-host disease,and four patients developed chronic graft-versus-host disease;no transplantation-associated thrombotic microangiopathy was observed.Conclusion:For patients with MRD-positive B-ALL,blinatumomab as a bridge therapy for allo-HSCT can significantly reduce recurrence after transplantation,with fewer complica-tions that are easy to control.Multicenter randomized controlled clinical studies can be performed to further verify its efficacy and safety.

Dent disease is a rare X-linked recessive renal tubular disease characterized by low molecular weight proteinuria，hypercalcemia and nephrocalcinosis. It is also a major cause of tubular proteinuria in children. According to different causative genes，Dent disease can be divided into three types：type 1 is caused by mutations in the CLCN5 gene，accounting for about 60%-70%；type 2 is caused by mutations in the OCRL gene，accounting for about 15%-20%；type 3 has a similar clinical phenotype but no known pathogenic gene mutations. CLCN5 encodes the voltage-dependent 2Cl -/1H +exchange channel CIC-5，which is involved in proximal renal tubule endocytosis. Its mutations can cause a variety of proximal tubular dysfunction symptoms，mainly including low molecular weight proteinuria. The use of gene detection technology has resulted in an increase in reports on Dent disease year after year. At present，the specific mechanism underlying Dent disease remains unknown. This article reviews the research progress of CLCN5，hoping to provide new insight for the mechanism research of CLCN5 and the specific treatment of Dent disease type 1.

Evidence-based medicine (EBM) is a science that uses the best available research data to make decisions, and the core is that clinical decision-making is supported by the best research evidence. Incorporating EBM into traditional standardized residency training in hematology can foster residents' professional theoretical knowledge and clinical skills, improve the quality of standardized training, and provide ideas and methods for standardized training of hematology residents, which is worthy of further research and exploration.

Objective To investigate the effect of bronchoscopic balloon dilation treatment of different intervals on the tracheal intubation-induced subglottic stenosis in children. Methods Children with tracheal intubation-induced subglottic cicatricial stenosis were selected as the research objects. Among the 36 children with pure balloon dilation treatment, 20 cases were enrolled in the observation group and 16 cases were enrolled in the control group. In the observation group, electronic bronchoscopy was performed at 3 days after the first-time balloon dilation treatment, and those with grade 2 or higher stenosis received the second-time balloon dilation treatment. The follow-up treatment principle was as follows. If there was obvious retraction compared with the previous time and the stenosis was grade 2 or higher, the balloon dilation treatment would be performed again after an interval of 3 days; if there was no obvious retraction, the evaluation would be performed again after an interval of 2 weeks until there was no obvious retraction in the stenosis site under endoscopy for 3 times in 6 consecutive weeks, and the degree of stenosis was less than 25%, and then the electronic bronchoscopy evaluation would be stopped. In the control group, electronic bronchoscopy was performed 7 days after the first-time balloon dilation treatment, and those with grade 2 or higher stenosis received the second-time balloon dilation treatment. The follow-up treatment principle was as follows. If there was obvious retraction compared with the previous time and the stenosis was grade 2 or higher, the balloon dilation treatment would be performed again after an interval of 7 days; the evaluation method for those without obvious retraction was the same as the observation group. The follow-up duration ranged from 6 to 9 months. Results There was no significant difference in the total number of treatments and outcomes between the two groups (P>0.05). The treatment duration of the observation group was significantly shorter than that of the control group (P < 0.05). There were no significant differences in intraoperative complications such as bleeding, oxygen saturation decrease, heart rate decrease, and blood pressure decrease during anesthesia between the two groups (P>0.05). There were no significant differences in postoperative fever, aggravated laryngeal stridor, and dyspnea between the two groups (P>0.05). There were no significant differences in dyspnea, activity tolerance, and the need for long-term oxygen therapy between the two groups (P>0.05). Conclusion Most of the tracheal intubation-induced subglottic cicatricial stenosis in children has a good medium- and long-term effect through pure balloon dilation treatment. Shortening the interval of pure balloon dilation to 3 days can shorten the total treatment duration, alleviate the psychological burden of parents, but does not increase their economic burden. There are no significant differences in intraoperative and postoperative complications, outcomes, and long-term follow-up compared with the original interval of 5 to 7 days.

BACKGROUND: Exploring the underlying mechanism of rituximab resistance is critical to improve the outcomes of patients with diffuse large B-cell lymphoma (DLBCL). Here, we tried to identify the effects of the axon guidance factor semaphorin-3F (SEMA3F) on rituximab resistance as well as its therapeutic value in DLBCL. METHODS: The effects of SEMA3F on the treatment response to rituximab were investigated by gain- or loss-of-function experiments. The role of the Hippo pathway in SEMA3F-mediated activity was explored. A xenograft mouse model generated by SEMA3F knockdown in cells was used to evaluate rituximab sensitivity and combined therapeutic effects. The prognostic value of SEMA3F and TAZ (WW domain-containing transcription regulator protein 1) was examined in the Gene Expression Omnibus (GEO) database and human DLBCL specimens. RESULTS: We found that loss of SEMA3F was related to a poor prognosis in patients who received rituximab-based immunochemotherapy instead of chemotherapy regimen. Knockdown of SEMA3F significantly repressed the expression of CD20 and reduced the proapoptotic activity and complement-dependent cytotoxicity (CDC) activity induced by rituximab. We further demonstrated that the Hippo pathway was involved in the SEMA3F-mediated regulation of CD20. Knockdown of SEMA3F expression induced the nuclear accumulation of TAZ and inhibited CD20 transcriptional levels via direct binding of the transcription factor TEAD2 and the CD20 promoter. Moreover, in patients with DLBCL, SEMA3F expression was negatively correlated with TAZ, and patients with SEMA3F low TAZ high had a limited benefit from a rituximab-based strategy. Specifically, treatment of DLBCL cells with rituximab and a YAP/TAZ inhibitor showed promising therapeutic effects in vitro and in vivo . CONCLUSION Our study thus defined a previously unknown mechanism of SEMA3F-mediated rituximab resistance through TAZ activation in DLBCL and identified potential therapeutic targets in patients.

Crossmodal information processing in sensory cortices has been reported in sparsely distributed neurons under normal conditions and can undergo experience- or activity-induced plasticity. Given the potential role in brain function as indicated by previous reports, crossmodal connectivity in the sensory cortex needs to be further explored. Using perforated whole-cell recording in anesthetized adult rats, we found that almost all neurons recorded in the primary somatosensory, auditory, and visual cortices exhibited significant membrane-potential responses to crossmodal stimulation, as recorded when brain activity states were pharmacologically down-regulated in light anesthesia. These crossmodal cortical responses were excitatory and subthreshold, and further seemed to be relayed primarily by the sensory thalamus, but not the sensory cortex, of the stimulated modality. Our experiments indicate a sensory cortical presence of widespread excitatory crossmodal inputs, which might play roles in brain functions involving crossmodal information processing or plasticity.

Objective: To analyze the risk factors of frequent gout flare, and to evaluate its susceptibility to identify patients with≥2 acute attacks per year. Methods: A total of 579 of cases gout patients with no history of taking urate lowering treatment (ULT) in recent 12 months were enrolled. The patients were divided into frequent group (gout episodes≥twice per year) and non-frequent group(gout attacksResults: There were significant differences in involvement of upper limb joints, tophi, combining hypertension and renal stone between two groups. The two groups had no statistical differences in family history, gender, history of smoking and drinking, ratios of regular exercise, and combining diabetes, hepatic insufficiency, hypertriglyceridemia, hypercholesterolemia, and overweight/obesity. There was significant differences in the number of joints involved, the history of disease duration, the level of SUA and TG[(4.66±2.54) vs (2.77±1.64), (6.68±5.11) vs (5.14±3.89) years, (525.82±132.11) vs (489.33±139.81) μmol/L, (2.51±1.94) vs (2.05±1.22) mmol/L, P<0.05 or P<0.01]; There were no statistical differences in age of onset, SBP, DBP, age of initial diagnosis, fasting blood glucose, TC, creatinine, glomerular filtration rate, AST, ALT, body mass index, waist circumference, and waist-to-hip ratio. Logistic regression analysis indicated that a large number of joints involved and higher serum uric acid level were risk factors of frequent gout attacks. The ROC curve showed that the number of joints involved had qualified performance in identifying patients with frequent gout attacks. When the number of joints involved was >2, and the sensitivity, specificity, positive predictive value and negative predictive value were 77.8%, 43.3%, 85.6%, and 56.6%, respectively, and the difference was significant. Conclusion Higher SUA and a larger number of joints involved associate independently with frequent gout attacks. The number of joints involved at initial diagnosis>2, which can predict the frequent flare, and start ULT as earlier as possible. Patients with joints involved at initial diagnosis>2 are at greater risk of frequent gout flare.

Objective:To evaluate the image quality of dual-source computed tomography pulmonary angiography (DE-CTPA) with low-dose contrast agent using the advanced modeled iterative reconstruction (ADMIRE) method with 70 kVp and non-linear blending in overweight patients.Methods:Seventy patients (normal BMI, 35; overweight, 35) with suspected pulmonary embolization who underwent DE-CTPA between October 2018 and March 2019 were included in this study. The imaging protocol included assessments at 70 kV/sn150 kV with 30 ml of contrast agent, and images were obtained at 70 kVp and 150 kVp with and without linear blending. The CT value, SD value, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) of pulmonary arteries were compared and analyzed among groups 1 (70 kVp, normal BMI), 2 (non-linear blending, normal BMI), 3 (70 kVp, overweight), and group 4 (non-linear blending, overweight). The radiation dose parameters included CT volume dose index (CTDI vol), dose length product (DLP), and effective dose ( E). Results:The CT values for the pulmonary artery did not show significant differences among the four groups ( P>0.05). The SD value of the segmental artery in group 1 was higher than that in group 4 ( t=2.69, P<0.05). The SNR values of the pulmonary artery trunk and sub-segmental artery in group 2 were higher than those in group 3 ( t=1.44, 5.40, P<0.05), while the corresponding value of the left pulmonary artery trunk in group 2 was higher than those in groups 3 and 4 ( t=1.52, 1.52, P<0.05). The CNR values of the pulmonary artery trunk and sub-segmental artery in group 2 were higher than those in group 3 ( t=1.45, 5.01, P<0.05) and that of the left pulmonary artery trunk in group 2 was higher than those in groups 3 and 4 ( t=1.50, 1.50, P<0.05). The E values for normal BMI and overweight patients were(1.60±0.54)mSv and(1.88±0.45)mSv, respectively. Conclusions:For overweight patients, the CTPA protocol using ADMIRE with a 70 kV/sn150 kV scanning mode could yield diagnostic image quality with significantly lower radiation and contrast material doses.
