Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

ObjectiveTo investigate the effect of icariin (ICA) on the phenotype of dendritic cells (DCs) in heart tissue of the Dahl salt-sensitive myocardial remodeling model of rats and its regulation on the vitamin D system. MethodsMale Dahl salt-resistant rats were divided into a normal group, and male Dahl salt-sensitive rats were divided into a model group, low-, medium-, and high-dose ICA groups (30, 60, 120 mg·kg-1·d-1), and Vitamin D group (3×10-5 mg·kg-1·d-1). In addition to the normal group, the other groups were given an 8% high salt diet to establish a myocardial remodeling model and received intragastric administration after successful modelling once a day for six weeks. The dynamic changes in tail artery blood pressure were monitored, and detection of cardiac ultrasound function in rats was performed. Hematoxylin-eosin (HE) staining and Masson staining were used to observe the morphological changes in rat heart tissue. The phenotype of DCs and T helper cell 17 (Th17)/regulatory T cell (Treg) ratio were detected by flow cytometry. The mRNA and protein expression of vitamin D receptor (VDR), 1α-hydroxylase (CYP27B1), 24-hydroxylase (CYP24A1), forkhead frame protein 3 (FoxP3), solitaire receptor γt (RORγt), myocardial type Ⅰ collagen (ColⅠ), and type collagen (ColⅢ) in heart tissue was detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot. ResultsCompared with the normal group, the model group showed disordered arrangement and rupture of myocardial cells, nuclear condensation, significant edema of myocardial tissue, significant proliferation of collagen fibers in a network distribution, and a significant increase in tail artery blood pressure, left ventricular end diastolic diameter (LVEDD), and left ventricular end systolic diameter (LVESD) (P<0.05). The phenotype of cardiac DCs was CD40, CD80, and CD86, and the levels of major histocompatibility complex Ⅱ (MHC-Ⅱ), Th17 cells, and Th17/Treg were significantly increased (P<0.05). The mRNA and protein expression of CYP24A1 and RORγt in the heart, as well as the mRNA expression of ColⅠ and ColⅢ, were significantly increased (P<0.05). The left ventricular ejection fraction (LVEF), interventricular septal thickness (IVSD), and left ventricular posterior wall thickness (LVPWD) were significantly decreased (P<0.05). The phenotype of cardiac DCs such as CD11, CD11b, and Treg cells, were significantly reduced (P<0.05), while the mRNA and protein expression of cardiac VDR, CYP27B1, and FoxP3 were significantly decreased (P<0.05). Compared with the model group, the low-, medium-, and high-dose ICA groups and vitamin D group significantly reduced myocardial cell rupture and nuclear consolidation in rats. The high-dose ICA group and vitamin D group showed a small amount of myocardial cell rupture and nuclear consolidation, improving myocardial fiber arrangement to varying degrees and significantly reducing myocardial fiber rupture and proliferation. The tail artery blood pressure, LVEDD, and LVESD were significantly decreased in the low-, medium-, and high-dose ICA groups and vitamin D group (P<0.05), and the phenotype of cardiac DCs including CD40, CD80, CD86, MHC-Ⅱ, Th17 cells, and Th17/Treg were significantly decreased (P<0.05). The mRNA and protein expression of CYP24A1 and RORγt, and the mRNA expression of ColⅠ and ColⅢ in the heart were significantly decreased in the medium- and high-dose ICA groups and vitamin D group (P<0.05). The LVEF, IVSD, and LVPWD of myocardial remodeling model rats in the low-, medium-, and high-dose ICA groups and vitamin D group were significantly increased (P<0.05). The phenotypes of cardiac DCs including CD11, CD11b, and Treg cells were significantly increased in the medium- and high-dose ICA groups and the Vitamin D group (P<0.05). The mRNA and protein expressions of VDR, CYP27B1, and FoxP3 in the heart were significantly increased in the medium- and high-dose ICA groups and vitamin D group (P<0.05). ConclusionICA can regulate tail artery blood pressure, cardiac structural and functional damage, and myocardial tissue fibrosis and inhibit phenotype and functional maturation of DCs in heart tissue in the myocardial remodeling model of Dahl salt-sensitive rats. It can also affect the gene and protein expression of VDR, CYP24A1, and CYP27B1, achieving its intervention in Th17/Treg balance in the immune process of myocardial remodeling possibly by regulating vitamin D/VDR in heart tissue.

Acupuncture, a therapeutic treatment defined as the insertion of needles into the body at specific points (ie, acupoints), has growing in popularity world-wide to treat various diseases effectively, especially acute and chronic pain. In parallel, interest in the physiological mechanisms underlying acupuncture analgesia, particularly the neural mechanisms have been increasing. Over the past decades, our understanding of how the central nervous system and peripheral nervous system process signals induced by acupuncture has developed rapidly by using electrophysiological methods. However, with the development of neuroscience, electrophysiology is being challenged by calcium imaging in view field, neuron population and visualization in vivo. Owing to the outstanding spatial resolution, the novel imaging approaches provide opportunities to enrich our knowledge about the neurophysiological mechanisms of acupuncture analgesia at subcellular, cellular, and circuit levels in combination with new labeling, genetic and circuit tracing techniques. Therefore, this review will introduce the principle and the method of calcium imaging applied to acupuncture research. We will also review the current findings in pain research using calcium imaging from in vitro to in vivo experiments and discuss the potential methodological considerations in studying acupuncture analgesia.

Objective The volume and cortical thickness of gray matter in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO) were compared and analyzed by voxel⁃based morphometry (VBM) and surface⁃based morphometry (SBM), and the differences in the structural changes of gray matter in the two diseases were discussed. Methods A total of 21 MS patients, 16 NMO patients and 19 healthy controls were scanned by routine MRI sequence. The data were processed and analyzed by VBM and SBM method based on the statistical parameter tool SPM12 of Matlab2014a platform and the small tool CAT12 under SPM12. Results Compared with the normal control group (NC), after Gaussian random field (GRF) correction, the gray matter volume in MS group was significantly reduced in left superior occipital, left cuneus, left calcarine, left precuneus, left postcentral, left central paracentral lobule, right cuneus, left middle frontal, left superior frontal and left superior medial frontal (P<0. 05). After family wise error (FWE) correction, the thickness of left paracentral, left superiorfrontal and left precuneus cortex in MS group was significantly reduced (P<0. 05). Compared with the NC group, after GRF correction, the gray matter volume in the left postcentral, left precentral, left inferior parietal, right precentral and right middle frontal in NMO group was significantly increased (P<0. 05). In NMO group, the volume of gray matter in left middle occipital, left superior occipital, left inferior temporal, right middle occipital, left superior frontal orbital, right middle cingulum, left anterior cingulum, right angular and left precuneus were significantly decreased (P<0. 05). Brain regions showed no significant differences in cortical thickness between NMO groups after FWE correction. Compared with the NMO group, after GRF correction, the gray matter volume in the right fusiform and right middle frontal in MS group was increased significantly(P<0. 05). In MS group, the gray matter volume of left thalamus, left pallidum, left precentral, left middle frontal, left middle temporal, right pallidum, left inferior parietal and right superior parietal were significantly decreased (P<0. 05). After FWE correction, the thickness of left inferiorparietal, left superiorparietal, left supramarginal, left paracentral, left superiorfrontal and left precuneus cortex in MS group decreased significantly (P<0. 05). Conclusion The atrophy of brain gray matter structure in MS patients mainly involves the left parietal region, while NMO patients are not sensitive to the change of brain gray matter structure. The significant difference in brain gray matter volume between MS patients and NMO patients is mainly located in the deep cerebral nucleus mass.

ObjectiveTo investigate the effect of icariin (ICA)-mediated vitamin D system on peripheral blood dendritic cells (DCs) and helper T cells 17 (Th17)/regulatory T cells (Treg) balance in myocardial remodeling model of Dahl salt-sensitive rats. MethodFifty SPF Dahl salt-sensitive rats were divided into model group, vitamin D group (3×10-5 mg·kg-1·d-1), and high-, medium-, and low-dose ICA groups (120, 60, 30 mg·kg-1·d-1), and 10 Dahl salt-resistant rats were used as normal group. The myocardial remodeling model was established by feeding rats with a high-salt diet containing 8% NaCl. After six weeks of modeling, the normal group and the model group were given an equal volume of ultrapure water by gavage, and other groups were continuously administrated for six weeks. Cardiac echocardiography, hematoxylin-eosin (HE) staining, and Masson staining were used to observe the pathological changes in cardiac structure and fibrosis. The levels of serum 25(OH)D3, B-type N-terminal pro-brain natriuretic peptide (NT-ProBNP), interleukin (IL)-17, transforming growth factor (TGF)-β1, IL-12, and IL-10 were detected by enzyme-linked immunosorbent assay (ELISA). The phenotype of peripheral blood DCs and the ratio of Th17/Treg cells of rats were detected by flow cytometry. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were used to detect the mRNA and protein expressions of vitamin D receptor (VDR),1α-hydroxylase (CYP27B1), and 24-hydroxylase (CYP24A1) in peripheral blood DCs of rats. ResultCompared with the control group, the rats in the model group had pathological changes such as disordered arrangement of myocardial cells and cytoplasmic hypertrophy and swelling. Myocardial collagen fibers proliferated significantly, and the arrangement of myocardial fibers was disordered. The levels of serum 25(OH)D3 and IL-10 were significantly decreased, and the levels of serum IL-17, TGF-β1, IL-6, IL-12, and NT-ProBNP were significantly increased (P<0.05). The costimulatory molecules CD40, CD80, CD86, and MHC-Ⅱ were highly expressed in the peripheral blood DCs, and the expression of CD11 and CD11b was lower (P<0.05). The proportion of Th17 cells in the peripheral blood was significantly increased, and the proportion of Treg cells was decreased. The ratio of Th17/Treg was increased (P<0.05). The mRNA and protein expressions of CYP24A1 in peripheral blood DCs increased, and the mRNA and protein expressions of CYP27B1 and VDR decreased (P<0.05). Compared with the model group, the arrangement of myocardial fibers in each drug administration group was relatively regular, and the swelling of myocardial cells was significantly reduced. The pathological morphology of myocardial tissue was improved to varying degrees. The pathological changes in myocardial tissue were improved and alleviated to varying degrees. The drug could reduce the serum levels of NT-ProBNP, IL-17, TGF-β1, IL-6, and IL-12 and increase the level of serum 25(OH)D3 and IL-10 (P<0.05). The expression of costimulatory molecules CD40, CD80, CD86, and MHC-Ⅱ in the peripheral blood DCs of rats was decreased, and the expression of CD11 and CD11b molecules was increased (P<0.05). The drug could reduce the proportion of Th17 cells in peripheral blood and the ratio of Th17/Treg cells and increase the proportion of Treg cells (P<0.05). It could decrease the mRNA and protein expressions of CYP24A1 in peripheral blood DCs of rats and elevate the mRNA and protein expression of VDR and CYP27B1 (P<0.05). ConclusionICA can regulate the phenotype of peripheral blood DCs and the ratio of Th17/Treg cells by regulating the vitamin D system and play a role in improving myocardial remodeling from the perspective of immune balance.

Protein as the allergens could lead to allergy. In addition, a widespread class of allergens were known as glycans of N-glycoprotein. N-glycoprotein contained oligosaccharide linked by covalent bonds with protein. Recently,studies implicated that allergy was associated with glycans of heterologous N-glycoprotein found in food, inhalants, insect toxins, etc. The N-glycan structure of N-glycoprotein allergen has exerted an influence on the binding between allergens and IgE, while the recognition and presentation of allergens by antigen-presenting cells (APCs) were also affected. Some researches showed thatN-glycan structure of allergen was remodeled by N-glycosidase, such as cFase I, gpcXylase, as binding of allergen and IgE partly decreased. Thus, allergic problems caused by N-glycoproteins could potentially be solved by modifying or altering the structure ofN-glycoprotein allergens, addressing the root of the issue. Mechanism of N-glycans associated allergy could also be elaborated through glycosylation enzymes, alterations of host glycosylation. This article hopes to provide a separate insight for glycoimmunology perspective, and an alternative strategy for clinical prevention or therapy of allergic diseases.
