RESUMEN

BACKGROUND/PURPOSE: Double-filtration plasmapheresis (DFPP) can be used to remove circulating pathogenic molecules. By reclaiming filtered albumin, DFPP reduces the need for albumin and plasma replacement. Large proteins, such as fibrinogen, are removed. Our institution adopts a DFPP treatment protocol consisting of active surveillance of coagulation profiles and prophylactic supplementation of blood products containing fibrinogen. This study aims to investigate the effects of consecutive DFPP treatments on serial coagulation profiles and the risk of bleeding under this protocol. METHODS: Serial laboratory data and bleeding events at a single tertiary medical center were prospectively collected. Prophylactic transfusion of cryoprecipitate or fresh frozen plasma (FFP) was instituted if significant coagulopathy or a clinically evident bleeding event was observed. RESULTS: After the first treatment session, plasma fibrinogen levels decreased from 332 ± 106 mg/dL to 96 ± 44 mg/dL in the 37 study patients. In the following sessions, plasma fibrinogen levels were maintained at around 100 mg/dL under prophylactic transfusion. No major bleeding events were recorded, but five (14%) patients experienced minor bleeding. CONCLUSION: DFPP treatment might be performed safely along with active monitoring of coagulation profiles and prophylactic transfusion of cryoprecipitate or FFP.

RESUMEN

Metformin-induced sexual dysfunction is rare in patients with diabetes mellitus. Herein, we present the case of a 57-year-old man newly diagnosed with type 2 diabetes mellitus who developed erectile dysfunction following treatment with metformin 500 mg BD. Prior to taking metformin, he had well-controlled hypertension, hyperlipidaemia and normal sexual function. Two weeks after beginning metformin therapy, he was diagnosed with erectile dysfunction after experiencing persistent difficulty achieving an erection. After discontinuation of metformin, his sexual function returned to normal. To determine whether sexual dysfunction is caused by metformin, we rechallenged the patient with metformin 500 mg BD. After 15 days, he became impotent again, confirming that metformin was the most likely cause of his sexual problem. Metformin was stopped, and his sexual function returned to normal after 3 weeks. The adverse reaction is 'probable' according to the World Health Organization-Uppsala Monitoring Centre.

RESUMEN

Azithromycin dry suspension is one of the most commonly used drugs in pediatric clinic, but its taste masking has been difficult to achieve. 5 representative products of azithromycin dry suspension were chose to compare their tastes both using electronic tongue and human sensory evaluation methods, and there existed the differences of bitterness, later bitterness, graininess, and adhesion among these products. Raman micro-imaging was used to determine the difference in taste mainly due to different prescription ingredients and manufacturing techniques. Through mixing the dry suspensions with alkaline mixing solvent, the bad taste of each product was masked after evenly dispersing in the solvent, and their tastes were all close to the taste of the solvent. In the future, it is planned to investigate the stability and bioavailability of the solvent preparations, and then to give the medication suggestion of solvent preparation after ensuring their efficacy.

RESUMEN

A flavoring agent and a suspension agent were prepared for extemporaneous compounding. The stability of the two agents before and after drug loading was investigated, and the taste of the suspension after extemporaneous compounding was evaluated by electronic tongue technology. The two agents remained stable under the conditions of influence factor test, accelerated test and long-term test. The appearance properties of the two agents did not change. The relative density of the flavoring agent was maintained at 1.053-1.075, and the pH was stable at 4.2-4.5. The relative density of the suspension agent was maintained at 0.999-1.022, and the pH was stable at 4.0-4.5. Seven kinds of drugs, including warfarin sodium tablets and spironolactone tablets, were mixed with these two oral solvents, and the content uniformity and stability were detected respectively. The results showed that the preparations could be evenly dispersed and the physical and chemical properties were stable. The results of taste evaluation showed that in captopril group and chloral hydrate group, the flavoring agent had the best effect on taste correction. In warfarin sodium group, rifampicin group, spironolactone group, vitamin B1 group and vitamin B2 group, the blending agents had the best effect on taste correction.

RESUMEN

ObjectiveTo reveal the targets and molecular mechanisms of the action of Qiangxin Decoction (强心汤) for the treatment of chronic heart failure based on the combination of network pharmacology and molecular docking. MethodsThe active ingredients of Qiangxin Decoction were retrieved from TCMSP database, and the targets of chronic heart failure were screened by searching GeneCards, OMIM, TTD, PharmGkb, and DrugBank databases, and the intersections were taken to obtain the intersecting targets of Qiangxin Decoction for the treatment of chronic heart failure. STRING platform was used to construct the protein-protein interaction network (PPI), Cytoscape 3.8.0 software was used to calculate the network topology to screen the core targets, and R 4.2.3 was used to construct the “active ingredient-target” network by analyzing the GO enrichment analysis and KEGG pathway enrichment analysis. AutoDock 1.5.7 was used for molecular docking to predict the binding performance of active ingredients and core targets. ResultsSeventy-five intersecting targets were identified for the treatment of chronic heart failure with Qiangxin Decoction, among which the core targets were estrogen receptor 1 (ESR1, degree value=7), nuclear receptor coactivator 1 (NCOA1, degree value=8), glucocorticoid receptor (NR3C1, degree value=7), and nuclear receptor coactivator 2 (NCOA2, degree value=7). GO enrichment analysis showed that the top 3 items with the smallest P value in molecular function were G protein-coupled amine receptor activity, postsynaptic neurotransmitter receptor activity, and neurotransmitter receptor activity (P<0.01); the top 3 items with the smallest P value in biological process were adenylyl cyclase-activated adrenergic receptor signaling pathway, adrenergic receptor signaling pathway, and adenylyl cyclase-regulated G protein-coupled receptor signaling pathway (P<0.01); the top 3 items with the smallest P values in cellular composition were components of the postsynaptic membrane, synaptic membrane, and presynaptic membrane (P<0.01). KEGG enrichment analysis showed that the top 5 key signaling pathways were neuroactive ligand-receptor interactions, calcium signaling pathway, dopaminergic synapses, cocaine addiction, and cyclic guanosine monophosphate-protein kinase G (cGMP-PKG) signaling pathway. The molecular docking results showed that lignans and isoflavones had lower binding energies and more structural stability with the four core targets (ESR1, NCOA1, NR3C1, NCOA2). ConclusionThe treatment of chronic heart failure by Qiangxin Decoction was associated with neuroactive ligand-receptor interactions, calcium signaling pathway, dopaminergic synapses, chemoattractant-receptor activation, cGMP-PKG signaling pathway, lipids and atherosclerosis, and cAMP signaling pathway, and lignans and isoflavones may be the core active compounds in its treatment of chronic heart failure.

RESUMEN

Forty two general practice residents who participated in the standardized training in Suzhou Municipal Hospital from April to December 2022 were randomly divided into two groups with 21 in each group. The control group received the traditional teaching method, and the study group received additional training with a special management model for chronic obstructive pulmonary disease. After 3 months of training, the teaching effects were evaluated with the improved Mini Clinical Evaluation Exercise (Mini CEX) in two groups and the teaching satisfaction was also assessed. Compared with the control group, the study group showed significant better performance in outpatient service, including the treatment and rehabilitation planning ( t=3.82, P<0.001), humanistic care ( t=4.83, P<0.001), health education ( t=9.56, P<0.001), communication skills ( t=3.34, P=0.002), and overall performance ( t=3.13, P=0.003). The satisfaction of teaching in study group was also higher than that in the control group ( Z=-2.02, P=0.044). The study shows that incorporating the "specialized management of chronic obstructive pulmonary disease" model into the general practice standardized residency training can significantly improve the teaching effects.

RESUMEN

@#Tumor-associated macrophage promotes the progression of glioblastoma (GBM) by infiltrating into tumor tissue, yet its mechanism has not been fully elucidated.This paper aimed to investigate the mechanism of M2 macrophages in affecting the migratory capacity of GBM via secreting exosomes.Ultracentrifugation was used to extract exosomes; RNA sequencing was carried out to screen differentially expressed miRNAs; target prediction database was used to predict the possible target proteins of miRNA; Dual-luciferase reporter assay was performed to verify the interaction between miRNA and target genes; and the proliferation ability of tumor cells was detected by subcutaneous xenograft model in nude mice.Results showed that tumor-related macrophages were mainly M2 macrophages, and that exosomes secreted by M2 macrophages could promote the migration of glioma cells.Meanwhile, exosomes secreted by M2 macrophages transported miR-1260b and affected the migration of glioma cells through directly targeted AJAP1, suggesting that exosomes secreted by macrophages could affect the migration ability of GBM through transporting miR-1260b.

RESUMEN

Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

RESUMEN

ObjectiveBy exploring the volatile components, polysaccharide composition and changes in the contents of five carbohydrate components of Polygonatum cyrtonema rhizoma before and after processing, and then the effect of yellow rice wine on the odour formation of P. cyrtonema rhizoma was investigated. MethodThe volatile components of P. cyrtonema rhizoma before and after processing were detected by headspace gas chromatography-mass spectrometry(HS-GC-MS), and sample data were subjected to principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) using SIMCA 14.1, then the differences between these components of P. cyrtonema rhizoma before and after processing were screened according to the principle of variable importance in the projection(VIP) value>1. Crude carbohydrate components in raw and wine-processed P. cyrtonema rhizoma were subjected to oxime and silylation, the carbohydrate components were analyzed by gas chromatography-mass spectrometry(GC-MS/MS), and the relative contents of various components were calculated by peak area normalization, then quantitative analysis of four carbohydrate components was also carried out. ResultA total of 23 volatile components were identified from the raw products and the wine-processed products, including 15 components in raw products and 20 components in wine-processed products. Among them, 2-methylbutyraldehyde and isovaleraldehyde had a sweet odor and their contents increased after processing, but the contents of hexanal and caproic acid decreased, new components such as 2-acetylfuran and 5-methylfuranal were produced after processing. PCA and OPLS-DA results showed that there were significant differences between raw products and the wine-processed products, a total of 13 differential compounds were screened out, of which 7 showed an upward trend in relative content and 6 showed a downward trend. A total of 7 carbohydrate components, including 5 monosaccharides and 2 disaccharides, were identified in raw products and the wine-processed products. The results of determination showed that the contents of fructose, glucose, mannose and sucrose in P. cyrtonema rhizoma increased after wine-processing, and their increases were 4.54, 1.51, 2.93, 3.66 times, respectively. ConclusionAfter processing, the increase of aromatic flavor of P. cyrtonema rhizoma may be related to the increase of the contents of aldehydes such as 2-methylbutyraldehyde and isovaleraldehyde, while the decrease of raw flavor may be related to the decrease of the contents of volatile components such as hexanal and hexanoic acid, the increase of sweet flavor may be related to the increase of the contents of monosaccharides and oligosaccharides such as fructose and sucrose.

RESUMEN

Background Paraquat (PQ) is one of the environmental factors that can cause sporadic Parkinson's disease (PD). Microglia-mediated neuroinflammation plays an important role in the occurrence and development of PD. Our previous studies have found that low doses of PQ can activate BV-2 microglia to the M1 phenotype and exert pro-inflammatory effects, but the associated mechanism is not clear yet. Objective To explore the role of c-Jun N-terminal kinase (JNK)/activator protein 1 (AP-1) signaling pathway in PQ-induced activation of the NOD-like receptor thermal protein domain associated protoin 3 (NLRP3) inflammasome in microglia. Methods An in vitro microglia model was established. The cells were treated with 0, 0.03, 0.06,and 0.12 μmol·L−1 PQ for 24 h, the whole cell protein was extracted. The relative expression levels of JNK, AP-1 constituent proteins (c-Jun, c-Fos), NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), caspasse-1 precursor (pro caspase-1), interleukin-18 (IL-18), and interleukin-1β (IL-1β) were evaluated by Western blotting, to observe the effects of PQ exposure on JNK/AP-1 signaling pathway and NLRP3 inflammasome. After the treatment of 20 μmol·L−1 JNK inhibitor SP600125, the above proteins were detected again, to explore the driving effect of JNK/AP-1 signaling pathway on NLRP3 inflammasome activation. Results After PQ exposure, the relative expression levels of key proteins of JNK, c-Jun, and c-Fos, NLRP3, ASC, and pro caspase-1 in the 0.06 μmol·L−1 PQ group and the 0.12 μmol·L−1 PQ group were higher than those in the 0 μmol·L−1 PQ group (P<0.05), and the relative expression levels of IL-18 and IL-1β increased with higher exposure (P<0.05). After the treatment of JNK inhibitor SP600125, the relative expression levels of key proteins of JNK/AP-1 signaling pathway (JNK, c-Jun, and c-Fos), NLRP3 inflammasome (NLRP3, ASC, and Pro caspase-1), and inflammatory factors (IL-18 and IL-1β) in the control group, the 20 μmol·L−1 SP600125 group, and the 20 μmol·L−1 SP600125+0.06 μmol·L−1 PQ group were lower than those in the 0.06 μmol·L−1 PQ group (P<0.05). Conclusion PQ exposure can activate the JNK/AP-1 signaling pathway and subsequently drive the activation of NLRP3 inflammasome in BV-2 microglia to mediate neuroinflammatory responses..

RESUMEN

ObjectiveTo observe the pharmacodynamic effects of Cinnamomi Cortex on the incretin effect in the rat model of diabetes mellites (DM) induced by streptozotocin (STZ) and explore the underlying mechanism from glucagon-like peptide-1 (GLP-1) and dipeptidyl peptidase-4 (DPP-4). MethodForty SD rats were randomly assigned into blank, model, sitagliptin (0.1 g·kg-1), and low- and high-dose Cinnamomi Cortex (0.45 and 0.9 g·kg-1, respectively) groups. The DM rat model was established by a high-fat diet combined with intraperitoneal injection of 40 mg·kg-1 STZ in other groups except the blank group. The intervention lasted for 8 weeks. The status, body weight, water intake, food intake, and fasting blood glucose (FBG) of the rats were observed and determined. Hematoxylin-eosin staining was employed to reveal the pathological changes of the pancreas, and immunohistochemistry to detect the expression of glucagon in the pancreas. Biochemical assay was employed to measure the serum levels of lipid metabolism indexes such as total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL). Enzyme-linked immunosorbent assay was employed to determine the levels of glycosylated hemoglobin, insulin, glucagon, GLP-1, and glucose-dependent insulinotropic polypeptide (GIP) in rat serum, and Western blot to determine the protein levels of GLP-1 and DPP-4 in the pancreas. ResultAfter 8 weeks of intervention, the model group showed higher body weight, FBG, TC, TG, LDL, glycosylated hemoglobin, glucagon, insulin, and insulin resistance index and lower HDL, GLP-1, and GIP than the blank group (P<0.05, P<0.01). The Cinnamomi Cortex groups showed lower body weight, FBG, TC, TG, LDL, glycosylated hemoglobin, glucagon, insulin, and insulin resistance index and higher HDL, GLP-1, and GIP than the model group (P<0.05, P<0.01). The Cinnamomi Cortex groups showed recovered morphology of islet cells and no nucleus aggregation. Compared with the model group, the Cinnamomi Cortex groups showed declined levels of glucagon in the center of islet cells. Compared with the blank group, the model group showed up-regulated protein level of DPP-4 and down-regulated protein level of GLP-1 (P<0.01). Compared with the model group, the high-dose Cinnamomi Cortex groups showed down-regulated protein level of DPP-4 and up-regulated protein level of GLP-1 (P<0.05). ConclusionCinnamomi Cortex may reduce blood glucose and improve incretin effect to lower the blood glucose level by regulating DPP-4 and GLP-1 in DM rats.

Methods: This was a retrospective case series study. The clinical data of 266 patients with MDS-EB diagnosed in the First Affiliated Hospital of Zhengzhou University between April 2016 and November 2021 were analyzed. The observed indicators included blood routine counts, mutated genes, overall response rate (ORR), overall survival (OS), progression-free survival (PFS), and leukemia-free survival (LFS). The Kaplan-Meier method was used to depict the survival curves. The Log-rank test method was equally used to compare survival across groups and performed the Cox proportional hazard regression model for prognostic analysis. Results: In 266 patients with MDS-EB, 166 (62.4%) were men, and the median age was 57 (17-81) years. Moreover, there were included 26 and 240 patients in the SF3B1-mutated and SF3B1 wild-type groups. Patients in the SF3B1-mutated group were older [median age 65 (51, 69) years vs. 56 (46, 66) years, P=0.033], had higher white blood cell (WBC) counts [3.08 (2.35, 4.78) × 109/L vs. 2.13 (1.40, 3.77) × 109/L], platelet (PLT) counts [122.5 (50.5, 215.0) ×109/L vs. 49.0 (24.3, 100.8) × 109/L], absolute neutrophil counts (ANC) [1.83 (1.01, 2.88) × 109/L vs. 0.80 (0.41, 1.99) × 109/L]and occurrence of DNMT3A mutation [23.1% (6/26) vs. 6.7% (16/240)] (all P<0.05). The ORR were similar in both groups after 2 and 4 cycles of therapy (P=0.348, P=1.000). Moreover, the LFS (P=0.218), PFS (P=0.179) and OS (P=0.188) were similar across the groups. Univariate Cox analysis revealed that SF3B1 mutation did not affect the prognosis of patients with MDS-EB (OS: P=0.193; PFS: P=0.184). Conclusions: Patients with SF3B1 mutation were older, with greater WBC, PLT, and ANC, and SF3B1 mutation easily co-occurred with DNMT3A mutation. From this model, there were no significant differences in efficacy and survival of MDS-EB with or without SF3B1 mutation.

RESUMEN

Neonatal hypoxic-ischemic encephalopathy (HIE) is a common disease that affects brain function in neonates. At present, mild hypothermia and hyperbaric oxygen therapy are the main methods for the treatment of neonatal HIE; however, they are independent of each other and cannot be combined for synchronous treatment, without monitoring of brain function-related physiological information. In addition, parameter setting of hyperbaric oxygen chamber and mild hypothermia mattress relies on the experience of the medical practitioner, and the parameters remain unchanged throughout the medical process. This article proposes a new device for the treatment of neonatal HIE, which has the modules of hyperbaric oxygen chamber and mild hypothermic mattress, so that neonates can receive the treatment of hyperbaric oxygen chamber and/or mild hypothermic mattress based on their conditions. Meanwhile, it can realize the real-time monitoring of various physiological information, including amplitude-integrated electroencephalogram, electrocardiogram, and near-infrared spectrum, which can monitor brain function, heart rate, rhythm, myocardial blood supply, hemoglobin concentration in brain tissue, and blood oxygen saturation. In combination with an intelligent control algorithm, the device can intelligently regulate parameters according to the physiological information of neonates and give recommendations for subsequent treatment.
