RÉSUMÉ
BACKGROUND: Patients with hematological malignancies received multiple hypodermic injections of recombinant human granulocyte colony-stimulating factor. Procedural pain is one of the most common iatrogenic causes of pain in patients with hematological malignancies. It is also identified as the most commonly occurring problem in clinical care in the Department of Hematology and Oncology at Shenzhen University General Hospital. However, providing immediate relief from pain induced by hypodermic injection of recombinant human granulocyte colony-stimulating factor remains a major challenge. This trial aims to evaluate the safety and analgesic efficacy of a fixed nitrous oxide/oxygen mixture for patients with hematological malignancies and experiencing procedural pain caused by hypodermic injection of recombinant human granulocyte colony-stimulating factor in the department. METHODS: The nitrous oxide/oxygen study is a single-center, randomized, double-blind, placebo-controlled trial involving patients with hematological malignancies who require hypodermic injections of recombinant human granulocyte colony-stimulating factor for treatment. This trial was conducted in the Hematology and Oncology Department of Shenzhen University General Hospital. A total of 54 eligible patients were randomly allocated to either the fixed nitrous oxide/oxygen mixture group (n = 36) or the oxygen group (n = 18). Neither the investigators nor the patients known about the randomization list and the nature of the gas mixture in each cylinder. Outcomes were monitored at the baseline (T0), immediately after hypodermic injection of recombinant human granulocyte colony-stimulating factor (T1), and 5 min after hypodermic injection of recombinant human granulocyte colony-stimulating factor (T2) for each group. The primary outcome measure was the score in the numerical rating scale corresponding to the highest level of pain experienced during hypodermic injection of recombinant human granulocyte colony-stimulating factor. Secondary outcomes included the fear of pain, anxiety score, four physiological parameters, adverse effects, total time of gas administration, satisfaction from both patients and nurses, and the acceptance of the patients. DISCUSSION: This study focused on the safety and analgesic efficacy during hypodermic injection of recombinant human granulocyte colony-stimulating factor procedure. Data on the feasibility and safety of nitrous oxide/oxygen therapy was provided if proven beneficial to patients with hematological malignancies during hypodermic injection of recombinant human granulocyte colony-stimulating factor and widely administered to patients with procedural pain in the department.

BACKGROUND AND OBJECTIVES: The feasibility and safety of single-port laparoscopic surgery for left lateral liver lobectomy are largely unknown. This study is aimed at comparing the effectiveness and safety between single-port laparoscopic (SPL) and conventional multiport laparoscopic (CL) surgeries for hepatic left lateral sectionectomy. METHODS: A total of 65 patients receiving laparoscopic hepatic left lateral sectionectomy between January 2008 and July 2015 were included and divided into the SPL group (n = 40) and the CL group (n = 25). RESULTS: There was no significant difference in the operative time, estimated intraoperative blood loss, length of hospital stay, and incidences of postoperative complications (biliary leakage, hemorrhage, and contusion at incision) between groups (all P > 0.05). However, the SPL group had a significantly lower VAS pain score (at 24 h but not 7 days postoperation) and higher cosmetic satisfaction scores (at both 2 months and 6 months postoperation) than the CL group (all P < 0.01). Moreover, multivariate linear regression analysis further confirmed the superior pain score and cosmetic outcome in the SPL group. CONCLUSIONS: Single-port laparoscopic hepatic left lateral sectionectomy is a safe and feasible treatment for patients with lesions in the left hepatic lobe. Patients with benign lesions in the left hepatic lobe are more suitable to receive single-port laparoscopic hepatic left lateral sectionectomy than those with malignancies.
RÉSUMÉ
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of leukemia patients can improve overall survival and disease-free survival, and reduce relapse. Although the allo-HSCT is more widely used in the treatment of leukemia, but the graft-versus-host disease (GVHD) and cytomegalovirus (CMV) infections are the common complications, and are the major cause of mortality for patients following allo-HSCT. Previous studies showed that there might be a mutual promotive relationship between GVHD and CMV infection, but the clear relationship remained to be elucidated. The relationship of GVHD and CMV has been the focus of clinical research. Recently, a great progress has been made on researches of the relationship and its mechanism between GVHD and CMV infection. In this article, the relationship and its mechanism between GVHD and CMV infection after allo-HSCT are reviewed.

In recent years, standardized treatment based on the risk stratification has been applied to clinical diagnosis and treatment of leukemia, which significantly improves the remission rate of ALL. However, relapse after remission remains an important challenge for long term efficacy. Chromosomal karyotype analysis is often used clinically to study the genetic features of ALL. As leukemia-specific markers, the cytogenetic and molecular genetic abnormalities can be used to evaluate prognosis and make an effective and optimal therapy. Furthermore, they are also used to track minimal residual disease. Therefore, the cytogenetic and molecular genetic abnormalities may become a monitor and a new target for the treatment of leukemia. This review briefly introduces the structure and physiological function of B-ALL associated cytogenetic and molecular genetic abnormalities, focusing on their prognostic effect on B-ALL.
