Background: Relapse was the major cause of treatment failure in patients with myeloid malignancies after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Patients who still suffer from the disease while cannot be detected by morphological analysis can be identified by the minimal residual disease (MRD) monitoring. The most used first-line regimens for MRD are immunotherapies.

Graft failure is a fatal complication following allogeneic stem cell transplantation where a second transplantation is usually required for salvage. However, there are no recommended regimens for second transplantations for graft failure, especially in the haploidentical transplant setting. We recently reported encouraging outcomes using a novel method (haploidentical transplantation from a different donor after conditioning with fludarabine and cyclophosphamide).

Article Synopsis
  • The study aimed to compare the effectiveness of two surgical methods for treating popliteal cysts: arthroscopic drainage and resection.
  • A total of 54 patients, aged 44 to 72, were treated, with 24 undergoing drainage (group A) and 30 receiving resection (group B), followed up for up to 2 years to assess outcomes like pain relief and knee function.
  • Both methods showed significant improvement in symptoms, with minimal complications; however, drainage had a shorter operation time and less bleeding compared to resection, though some patients in the drainage group experienced a recurrence of cysts.

In patients with t(8;21) acute myeloid leukemia (AML) with recurrent measurable residual disease (MRD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT), pre-emptive interferon-α therapy and donor lymphocyte infusion are noneffective in 30%-50% of patients. Avapritinib is a novel tyrosine kinase inhibitor targeting KIT mutations. We retrospectively report about 20 patients with t(8;21) AML and KIT mutations treated with avapritinib after allo-HSCT with MRD and most failing to respond to immunotherapy.

Cytokine storm development is a major cause of many transplant-related complications, especially during the conditioning regimen. This study aimed to characterize the cytokine profile and determine its prognostic impact during conditioning in patients undergoing subsequent haploidentical stem cell transplantation. A total of 43 patients were enrolled in this study.

Objective: To explore clinical effect of lateral locking compression plate combined with medial buttress plate in treating osteoporotic comminuted fractures of proximal humerus.

Methods: From May 2017 to December 2021, 12 patients with osteoporotic comminution of proximal humerus were treated by lateral locking compression plates combined with medial buttress plates, including 5 males and 7 females, aged from 55 to 78 years old, bone mineral density(BMD) less than -2.5 g/cm3, the time from injury to operation was from 2 to 6 days.

Background: Human leukocyte antigen-identical sibling donor (ISD)-hematopoietic stem cell transplantation (SCT) is a potentially curative treatment for high-risk pediatric acute myeloid leukemia (AML). A haploidentical donor (HID) is readily available to almost all children. Previous studies have demonstrated that patients with HID-SCT had similar outcomes compared to ISD-SCT for pediatric and adult AML.

Objective: To explore the surgical method and clinical outcome of modified osteotomy of olecranon for the treatment of inter-condylar fracture of humerus.

Methods: From May 2007 to December 2012, 32 patients of intercondylar fracture of humerus were treated surgically through the approach of modified osteotomy of olecranon. The patients were 21 males and 11 females with a mean age of 46.

Since late 2010, porcine epidemic diarrhea virus (PEDV) has been re-emerging in central China. To explore the possible reason of the PEDV outbreaks, twelve PEDV field strains were isolated from different swine breeding farms in central China during 2010-2012, and molecular diversity, phylogenetic relationships of these strains with other PEDV reference strains were investigated. Sequence analysis of S, M and ORE3 genes revealed that the central China PEDV isolates had several specific nucleotides and amino acids which were different from PEDV reference strains.

Article Synopsis
  • Porcine epidemic diarrhea (PED) resurged in central China starting in October 2010, leading to significant impacts on pig populations.
  • Researchers studied the M and ORF3 genes of 15 PEDV strains from central China using genetic analysis techniques, revealing changes in nucleotides and amino acids compared to a reference strain.
  • Phylogenetic analysis classified these strains into a new genotype (G3), showing close genetic relationships with certain Korean and Thai strains while differing from European and vaccine strains, indicating rapid variation in PEDV.

Objective: To investigate the clinical application of the reversed sural neurovascular fasciocutaneous flap.

Methods: From January 2007 to May 2009,10 patients (6 males and 4 females) with soft tissue defects on lower limbs were treated by reversed sural neurovascular fasciocutaneous flap. The end-to-side neuroanastomosis were used to reinnervate the flap and microsurgery was used for anastomosing small saphenous vein.
