Full-Endoscopic Isolation Zone Technique for the Treatment of Lumbar Disc Herniation.

Lumbar disc herniation (LDH) is a type of serious sinus or sciatic nerve dysfunction caused by nucleus pulposus protrusion and annulus fibrosus tears. Its clinical symptoms often include severe low back pain, limited lumbar movement, sciatic nerve pain in the lower limbs, and even cauda equina syndrome. The common treatment for LDH is a conservative treatment scheme involving medicine, rest, and physical therapy.

Adaptive immunity-related gene expression profile is correlated with clinical phenotype in patients with acute myeloid leukemia.

Background: Acute myeloid leukemia (AML) is a common and lethal hematopoietic malignancy that is highly dependent on the immune microenvironment. However, light has yet to be shed on the landscape of adaptive immunity-related genes. This work aimed to uncover the novel molecular events in AML and potential therapeutic strategies for AML treatment.

Haematologic malignancies with unfavourable gene mutations benefit from donor lymphocyte infusion with/without decitabine for prophylaxis of relapse after allogeneic HSCT: A pilot study.

Relapse is the main cause of treatment failure for leukaemia patients with unfavourable gene mutations who receive allogeneic haematopoietic stem cell transplantation (allo-HSCT). There is no consensus on the indication of donor lymphocyte infusion (DLI) for prophylaxis of relapse after allo-HSCT. To evaluate the tolerance and efficacy of prophylactic DLI in patients with unfavourable gene mutations such as FLT3-ITD, TP53, ASXL1, DNMT3A or TET2, we performed a prospective, single-arm study.

Background: Intravenous (IV), topical and combination of both application of tranexamic acid (TXA) can reduce blood loss, hemoglobin drop, and transfusion rate in patients following total hip arthroplasty (THA). Lately, published articles reported that oral TXA had as similar blood-saving as IV and topical TXA in THA. The purpose of this meta-analysis is to investigate the efficiency and safety of oral TXA in THA.

Cell Division Cycle Associated 8 Is a Key Regulator of Tamoxifen Resistance in Breast Cancer.

Purpose: Breast cancer (BC) is one of the most common malignancies globally, and millions of women worldwide are diagnosed with BC every year. Up to 70% of BC patients are estrogen receptor (ER)-positive. Numerous studies have shown that tamoxifen has a significant therapeutic effect on both primary and metastatic ER-positive BC patients.

CDCA8 is a key mediator of estrogen-stimulated cell proliferation in breast cancer cells.

Endocrine therapy is effective in the early stage of breast cancer treatment, and most tumor cells will gain the ability to proliferate under residual amounts of estrogen, which will cause the recurrence of the disease. The role of cell division cycle associated 8 (CDCA8) in Estradiol (E2)-stimulated breast cancer cells growth is investigated in this research. CDCA8 showed higher mRNA expression in E2-stimulated MCF7 and T47D cells, and such an increase could also be observed in tumor samples.

Correlation between Interleukin-17 gene polymorphism and osteoarthritis susceptibility in Han Chinese population.

Background: Interleukin-17 (IL-17), a pleiotropic cytokine, plays a significant role in the inflammatory diseases.
