Objective:To explore the diagnosis and treatment of acquired hemophilia A (AHA ) based on the analysis of clinical data.Methods:A retrospective analysis was conducted on the clinical manifestations,laboratory characteristics,treatment,and outcomes of 25 patients diagnosed with AHA who were admitted to the Second Hospital of Hebei Medical University. Results:Among all patients,11 cases had secondary factors,including 5 cases of autoimmune diseases,3 cases of pregnancy-related disease,1 case of pemphigoid,1 case of Graves'disease,and 1 case of monoclonal gammaglobulinemia of unknown significance (MGUS ).The bleeding sites include the skin,mucous membrane,muscle,joint cavity and brain tissue.Twenty-three patients were treated with prednisone combined with cyclophosphamide (CP regimen),one patient with rituximab combined with cyclophosphamide because of femoral head necrosis,and one case with rituximab monotherapy because of gastrointestinal bleeding after prednisone treatment. Among them,23 cases achieved complete remission (CR),2 cases were partial remission (PR),and 8 cases relapsed after CR.All of 10 patients including 2 cases with PR and 8 relapsed cases after CR were treated with rituximab.At last,8 patients achieved CR,and 2 patients (both were patients with recurrence after first CR)achieved PR.These two patients achieving PR were treated with low-dose rituximab combined with bortezomib (RB regimen ).One patient reached CR after 4 cycles and the other reached CR after 6 cycles of RB regimen.After CR,4 of the 10 patients treated with rituximab received maintenance therapy with rituximab monotherapy for 1.5 to 2 years,in which,none of them relapsed.Among the 6 patients who did not receive maintenance therapy,4 patients relapsed after CR,and the median time to relapse was 15 months.Eight patients treated with CP regimen developed common infections,and two patients treated with rituximab developed severe pneumonia.All 25 patients survived until the end of follow-up.Conclusion:Skin ecchymosis,mucous hemorrhage and muscle hematoma are the most common hemorrhagic manifestations in AHA,and joint hemorrhage and cerebral hemorrhage can also occur.CP regimen is the preferred option of first-line therapy for AHA.Rituximab can be used for patients with steroid contraindication or who failed to respond to the above therapy or relapsed after effective treatment,and maintenance therapy is recommended to reduce the risk of recurrence.Meanwhile,close attention should be paid to the occurrence of infection events during rituximab treatment.Rituximab in combination with bortezomib can also be used in patients with refractory or relapsing AHA.

Chromodomain-helicase-DNA-binding protein 1 (CHD1) deletion is among the most common mutations in prostate cancer (PCa), but its role remains unclear. In this study, RNA sequencing was conducted in PCa cells after clustered regularly interspaced palindromic repeat (CRISPR)/CRISPR-associated protein 9 (Cas9)-based CHD1 knockout. Gene set enrichment analysis (GSEA) indicated upregulation of hypoxia-related pathways. A subsequent study confirmed that CHD1 deletion significantly upregulated hypoxia-inducible factor 1α (HIF1α) expression. Mechanistic investigation revealed that CHD1 deletion upregulated HIF1α by transcriptionally downregulating prolyl hydroxylase domain protein 2 (PHD2), a prolyl hydroxylase catalyzing the hydroxylation of HIF1α and thus promoting its degradation by the E3 ligase von Hippel-Lindau tumor suppressor (VHL). Functional analysis showed that CHD1 deletion promoted angiogenesis and glycolysis, possibly through HIF1α target genes. Taken together, these findings indicate that CHD1 deletion enhances HIF1α expression through PHD2 downregulation and therefore promotes angiogenesis and metabolic reprogramming in PCa.

Diosgenin, a steroidal sapogenin, obtained from Trigonella foenum-graecum, Dioscorea, and Rhizoma polgonati, has shown high potential and interest in the treatment of various cancers such as oral squamous cell carcinoma, laryngeal cancer, esophageal cancer, liver cancer, gastric cancer, lung cancer, cervical cancer, prostate cancer, glioma, and leukemia. This article aims to provide an overview of the in vivo, in vitro, and clinical studies reporting the diosgenin's anticancer effects. Preclinical studies have shown promising effects of diosgenin on inhibiting tumor cell proliferation and growth, promoting apoptosis, inducing differentiation and autophagy, inhibiting tumor cell metastasis and invasion, blocking cell cycle, regulating immunity and improving gut microbiome. Clinical investigations have revealed clinical dosage and safety property of diosgenin. Furthermore, in order to improve the biological activity and bioavailability of diosgenin, this review focuses on the development of diosgenin nano drug carriers, combined drugs and the diosgenin derivatives. However, further designed trials are needed to unravel the diosgenin's deficiencies in clinical application.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective:To explore the effect of laryngeal massage combined with feeding training on swallowing function and quality of life in patients with poststroke swallowing disorders.Methods:From November 2021 to October 2022, convenience sampling was used to select 148 patients with poststroke swallowing disorders in the Department of Neurosurgery and Rehabilitation at the North China University of Science and Technology Affiliated Hospital. The patients were divided into a control group, a laryngeal massage group, a feeding training group, and a combination group using the random number table method, with 37 cases in each group. The control group was given routine nursing, while the laryngeal massage group and feeding training group respectively received laryngeal massage and feeding training on the basis of routine nursing. The combination group underwent laryngeal massage combined with feeding training on the basis of routine nursing. Before and after 2, 4, and 8 weeks of intervention, the Water Swallowing Test, Standardized Swallowing Assessment (SSA), and Chinese version Swallowing Quality of Life Questionnaire (SWAL-QOL) were used to compare the swallowing function and quality of life of four groups of patients with poststroke swallowing disorders.Results:After 2, 4, and 8 weeks of intervention, the Water Swallowing Test rating and efficacy evaluation of the 4 groups of patients with poststroke swallowing disorders were better than those before intervention ( P<0.05). Moreover, the SSA scores decreased compared to before intervention ( P<0.05), and the SWAL-QOL scores increased compared to before intervention ( P<0.05). The Water Swallowing Test efficacy evaluation and SWAL-QOL scores in the combined group were higher than those of the other groups ( P<0.05), while the SSA scores were lower than those of the other groups ( P<0.05) . Conclusions:Laryngeal massage and feeding training can improve the swallowing function and quality of life of patients with poststroke swallowing disorders, and the combination of the 2 interventions has a significant effect.

AIM:To observe the early variation trend of the vault after phakic posterior chamber implantable collamer lens/toric implantable collamer lens(ICL/TICL V4c)implantation and analyze the related influencing factors.METHODS:In this retrospective study, a total of 49 patients(98 eyes)who underwent ICL/TICL V4c implantation in the Lanzhou Huaxia Eye Hospital from October 2020 to March 2021 were enrolled. Preoperative ocular biometric parameters were collected, including spherical equivalent(SE), intraocular pressure, axial length, anterior chamber depth(ACD), lens thickness(LT), central corneal thickness, anterior chamber angle(ACA), anterior chamber volume(ACV), white to white corneal diameter(WTW), mean keratometry K1 and K2, and intraoperative implantation size of ICL. The vault was measured by anterior segment optical coherence tomography(AS-OCT)at 1, 3d, 1wk and 1mo after surgery. The patients were divided into insufficient vault group(<250μm, 12 eyes), normal vault group(250-750μm, 62 eyes)and excessive vault group(>750μm, 24 eyes)according to the vault at 1mo after surgery. The factors affecting the postoperative vault were analyzed.RESULTS:The mean vault values at 1 and 3d, 1wk and 1mo after surgery were 591.05±293.44, 599.62±309.78, 592.22±301.49 and 586.69±285.63μm, respectively. There were significant differences in WTW, ACA, ACV, ACD, ICL size and LT at 1mo after surgery(all P<0.05). The regression equation of vault at 1mo after surgery was as follows: vault(μm)=-3142.19+388.25×WTW+10.40×ACA-301.63×LT(R=0.674, R2=0.454, adjusted R2=0.436). WTW had the greatest influence on vault at 1mo after surgery(β=0.47, P<0.001), followed by LT(β=-0.34, P<0.001)and ACA(β=0.17, P=0.047).CONCLUSION:WTW, ACA and LT were the main factors that affected and predicted the vault at 1mo after ICL/TICL V4c implantation.

Purpose:
To identify more accurate predictors of upper urinary tract dilatation (UUTD) in neurogenic bladder (NB) children, we studied the relationship among urodynamic parameters at different bladder filling stages, detrusor leak point pressure (DLPP) and UUTD.
Methods:
A total of 158 children (3–16 years) with NB were included and then divided into 2 groups according to whether their NB diagnosis was complicated with UUTD: the UUTD group (39 patients) and those without UUTD group (control group, 119 patients). The bladder filling phase was divided into 3 equal parts: the early, middle, and end filling stages. The bladder compliance (BC) and detrusor pressure (△Pdet) at each phase and DLPP at the end filling stage were recorded.
Results:
A BC<8 mL/cm H2O both in the middle and end stages is more specific than a BC<9 mL/cm H2O in the end stage (72%, 73%, vs. 66%), and △Pdet >8 cm H2O in the early stage, 20 cm H2O in the middle stage and 25 cm H2O in the end stage are more sensitive than △Pdet >40 cm H2O in the end stage (82%, 85%, 85%, vs. 49%). A DLPP cutoff value of 20 cm H2O showed higher sensitivity for predicting UUTD than 40 cm H2O.
Conclusions
Low BC and a high △Pdet in the middle and end filling stages are more accurate factors than classic indicators for predicting UUTD. In addition, a DLPP value of >20 cm H2O in the end bladder filling stage shows high sensitivity.
