This report presents the management of a critically ill 36-year-old woman diagnosed with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph +ALL) at 28 weeks of gestation. The patient rapidly deteriorated, developing disseminated intravascular coagulation (DIC) , diffuse alveolar hemorrhage (DAH) , septic shock, and multi-organ dysfunction, necessitating admission to the hematological intensive care unit. Given her critical condition and advanced pregnancy, a chemotherapy-free induction regimen comprising imatinib and dexamethasone was initiated, alongside comprehensive supportive measures, including mechanical ventilation, continuous renal replacement therapy (CRRT) , broad-spectrum antibiotics, and high-dose corticosteroids. During treatment, intrauterine fetal demise occurred, and a stillborn was delivered following obstetric intervention. With aggressive treatment, the patient's respiratory failure, DIC, and DAH gradually resolved, and she achieved complete remission. She subsequently received consolidation chemotherapy, CAR-T cell therapy, and allogeneic hematopoietic stem cell transplantation, achieving sustained complete molecular remission on long-term follow-up. This case demonstrates that for critically ill pregnant patients with Ph + ALL, a chemotherapy-free regimen of targeted therapy and corticosteroids, when combined with intensive supportive care, is a safe and effective approach that may offer a therapeutic option for similar cases.

Objective:This study retrospectively analyzed the clinical characteristics of patients newly diagnosed with acute myeloid leukemia (AML) who were admitted to the hematology intensive care unit (HCU) with critical illness. It also examined factors associated with critical illness and early mortality in these patients.Methods:Clinical data were collected from 91 newly diagnosed AML patients admitted to the HCU of the Department of Hematology, First Affiliated Hospital of Soochow University, from October 2020 to 2024. Reasons for HCU admission, major therapeutic interventions, and risk factors for critical illness and early mortality were analyzed.Results:The median time from diagnosis to HCU admission was 3 days ( IQR: 3–9 days), and the median HCU stay was 10 days ( IQR: 3–23 days). Of the 91 patients, 71 were admitted to the HCU before induction chemotherapy, while 20 were transferred to the HCU after its initiation. The leading causes of HCU admission were pulmonary infection (78.0% ), respiratory failure (44.0% ), hepatic insufficiency (28.6% ), renal insufficiency (27.5% ), disseminated intravascular coagulation (DIC; 25.3% ), and sepsis (23.1% ). Median Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) and SOFA scores at HCU admission were 14 ( IQR: 11–18) and the median Sepsis Related Organ Failure Assessment (SOFA) score was 7 ( IQR: 4, 10). Major HCU interventions included vasoactive drugs, noninvasive and invasive mechanical ventilation, continuous renal replacement therapy, therapeutic leukocyte clearance, and cardiopulmonary resuscitation. Among patients receiving induction chemotherapy, the composite complete remission rate was 65.4%, and the overall remission rate was 88.5%. Thirty-five (38.5% ) patients died within 28 days of HCU admission. Independent risk factors for 28-day mortality were DIC ( OR=9.350, 95% CI 1.999–43.745, P=0.005), sepsis ( OR=6.817, 95% CI 1.571–29.582, P=0.010), and cardiac insufficiency ( OR=12.281, 95% CI 2.385–63.254, P=0.003) . Conclusion:The main reason for HCU admission in newly diagnosed critically ill AML patients was pulmonary infection. Nearly 40% of patients experisenced early death, and DIC, sepsis, and heart failure were factors influencing early mortatlity.

Getah virus(GETV)is an arbovirus capable of infecting humans and vertebrates such as horses and pigs via blood-sucking mosquitoes,which is extremely harmful to the livestock indus-try.Current monitoring methods are time-consuming,costly,and dependent on specialized instru-ments.These characteristics hinder rapid detection in clinical samples.Therefore,the development of a simple,rapid,specific,and sensitive method for detecting GETV antigen is crucial for the pre-vention and control of GETV.In this study,a GETV E1 monoclonal antibody strain SD17/09-E1-mAb was prepared by a prokaryotic expression system for GETV E1 protein expression,and a col-loidal gold double-antibody sandwich assay encapsulating two strains of GETV E1 monoclonal an-tibody wasestablished.The results showed that the prepared colloidal gold test strips had good sen-sitivity and did not cross-react with other common porcine virus-positive tissue samples;the test strips had a high compliance rate with the IFA assay for GETV,and could be stored at 37 ℃ for one month and at room temperature for at least three months.In this study,a colloidal gold anti-surveillance test strip for rapid detection of GETV was successfully prepared,which provides a powerful tool for GETV detection.

Objective To investigate the clinical efficacy of transurethral plasma electrotomy with rod electrode and end-to-end urethral anastomosis in the treatment of short urethral stricture.Methods 125 male patients with short urethral stricture(＜2 cm)who were admitted to our hospital from January 2014 to December 2020 were retrospectively analyzed.According to different surgical methods,they were divided into transurethral plasma resection with rod electrode(minimally invasive group)and urethral end-to-end anastomosis(open group).According to the length of urethral stricture,the minimally invasive group was divided into minimally invasive group 1(stricture length≤1 cm),minimally invasive group 2(stricture length1-2 cm),open group 1(stricture length ≤1 cm)and open group 2(stricture length 1-2 cm).The four groups were compared with each other,and the surgical success rates were compared between the four groups.Results The success rate of the minimally invasive group 1 and the open group 1 was 88.57％and 93.10％,respectively.There was no significant difference between the two groups(P＞0.05).The surgical success rate of the minimally invasive group 2 and the open group 2 was 67.86％and 90.91％,respectively.The surgical success rate of the minimally invasive group 2 was significantly lower than that of the open group 2.The difference was statistically significant(P＜0.05).The surgical success rate of minimally invasive group 1 and minimally invasive group 2 was 88.57％and 67.86％,respectively,the difference was statistically significant(P＜0.05).The success rate of operation in the open group 1 and the open group 2 was 93.10％and 90.91％,respectively,and there was no significant difference between the two groups(P＞0.05).Conclusion Transurethral plasma resection with rod electrode is preferred for urethral stricture with length≤1 cm,because the success rate of this surgery is the same as that of open surgery,and the surgical trauma is small and the recovery is fast.For 1-2 cm urethral stricture,minimally invasive surgery has less trauma and faster recovery,but open surgery has a higher success rate.The choice of surgical method needs to weigh the advantages and disadvantages and take comprehensive consideration.

Objective:To explore the genetic etiology of a child with primary hypertrophic osteoarthropathy(PHO).Methods:A child who was admitted to Zhongnan Hospital of Wuhan University on July 27, 2021 was selected as the study subject. Genomic DNA was extracted from peripheral blood samples of the child and his parents and subjected to whole exome sequencing. Suspected splicing variant was verified by Sanger sequencing of family members. In vitro function was validated through a minigene assay, whilst the suspected exonic deletion was validated by long-fragment PCR. This study was approved by the Children′s Hospital Affiliated to Zhengzhou University (Ethics No. 2023-K-011). Results:Whole exome sequencing revealed that the child has harbored compound heterozygous variants of HPGD gene, including a heterozygous deletion (Exon 3 del) derived from his father and a splicing variant (c.421+ 1G>T) derived from his mother. Long-fragment PCR verified that the child and his father had both harbored a 7 565 bp heterozygous deletion (c.218-1304_324+ 6156del), whilst the minigene assay proved that the splicing variant has resulted in skipping of exon 4. Conclusion:The heterozygous c. 218-1304_324+ 6156del deletion and the c. 421+ 1G>T splicing variant of the HPGD gene probably underlay the pathogenesis in this child. Above finding has enriched the mutational spectrum of the HPGD gene and provided a basis for genetic counseling and prenatal diagnosis for this family.
