ABSTRACT
Macrophages are important innate immune cells that play essential roles in the inflammatory response. The phenotypic plasticity of macrophages enables them to be polarized into distinct gene phenotypes under different immune microenvironments to regulate the process of inflammation. The study of macrophage metabolic reprogramming aims to clarify the influence of key metabolic pathways on the regulation of different polarization states and related functions of macrophages. This review focuses on the relationship between the four key metabolic pathways [glycolysis, tricarboxylic acid (TCA) cycle, fatty acid metabolism and amino acid metabolism] and the distinct gene phenotypes of macrophages. It also reveals the metabolic regulation of the immune function of macrophage cells thus to provide new ideas and methods for the study of macrophage polarization-related process of inflammation.
ABSTRACT
Metabolic reprogramming is the response of cells to environmental changes, such as cell activation, proliferation and differentiation, which involves changes in metabolism-related enzymes, metabolites and metabolic pathways. Sepsis-associated immune cells undergo metabolic reprogramming in response to inflammatory signals, which not only provides biological energy and biosynthesis requirements, but also determines cell fate and function in a highly specific way. In this paper, the changes in glycolysis, tricarboxylic acid cycle, oxidative phosphorylation and other glucose metabolism pathways of macrophages, T lymphocytes, dendritic cells, neutrophils and other sepsis related immune cells are described, so as to provide feasibility for future research and metabolic therapy.

ABSTRACT
Objective: To investigate the effects of laparoscopic surgery combined with triptorelin acetate, gestrinone and mifepristone on pregnancy rate, pregnancy outcome, long-term recurrence and adverse reactions in patients with endometriosis [EMT] complicated with infertility
Methods: In this study, 150 patients with EMT and infertility were selected and randomly divided into triptorelin group [group A], gestrinone group [group B] and mifepristone group [group C], with 50 people in each group. Treatment was with gonadotropin-releasing hormone [GnRH-a] after laparoscopic surgery
Results: The success rate of pregnancy in group A was higher than that in group B and C. The incidence of adverse pregnancy outcome was lower than that in group B and C. Kupperman score and subjective symptom score were lower than those in group B and C before treatment. Sex hormone level and CA125 level were significantly better. In the B and C groups and before treatment; the long-term recurrence rate was significantly lower than the B and C groups; the incidence of adverse reactions was similar
Conclusion: Laparoscopic surgery combined with GnRH-a can improve the success and good rate of pregnancy in EMT patients, reduce clinical symptoms, avoid long-term recurrence, and increase the risk of adverse reactions. Triptorelin acetate is superior to gestrinone and mifepristone
ABSTRACT
Sepsis is a high-risk factor for the death of critical patients. High density lipoprotein (HDL) are the major protective serum proteins, and the serum levels of HDL are closely related to the severity of sepsis. The anti-inflammatory and anti-oxidation properties of HDL, may be able to play an important role in the innate immune response. Thereby it may reduce the damage of septic shock and multiple organ dysfunction syndrome (MODS) in animals or human beings, and improve the prognosis. In order to unveil the metabolism of HDL in septic patients and its effects on both progression and prognosis of sepsis, this review not only focuses on the composition and structure of HDL, but also analyzes its pivotal role in inflammatory immune response and anti-oxidation.
ABSTRACT
Acute lung injury (ALI) is one of the most common clinical critical illnesses. Its severe stage is acute respiratory distress syndrome (ARDS), characterized by rapid onset and high mortality. There is no effective treatment. Based on many preclinical studies, mesenchymal stem cells (MSCs) have great potential as a therapeutic strategy for ALI, clinical trials are underway, and studies on the therapeutic effects of MSCs progressively deep into the molecular mechanism and continue to make new progress. However, the use of MSCs, their specific methods and risks, especially on the risk of iatrogenic tumor formation remains unresolved. In this paper, we reviewed the main problems in the application of MSCs in the treatment of ALI and the main problems in the application of MSCs in order to explore the feasibility and future direction of MSCs in the treatment of ALI.
ABSTRACT
Objective To investigate the clinical presentation,diagnosis,and surgical management of anti-N-methyl-D-aspartate (NMDA) receptor encephalitis.Methods One case of anti-NMDA receptor encephalitis in a previously healthy 17-year-old female related to the development of NMDA receptor autoantibodies triggered by an ovarian teratoma was reported.The related literature was reviewed and the clinical feature was summarized.Results Removal of the ovarian teratoma combined with intravenous immuneglobulin and corticosteroid proved curative with eventual resolution of the paraneoplastic disease process and associated psychiatric symptoms.Conclusion Increasingly,reports of anti-NMDA receptor encephalitis associated with ovarian teratomas,as well as a novel assay to measure these antibodies suggest an etiology for this disease process that may be amenable to prompt surgical excision.
