Effects of lactoprotein iron chelates on iron deficiency anaemia in rats / 预防医学

Objective@#To investigate the effects of lactoprotein iron chelates on rats with iron deficiency anaemia (IDA), so as to provide insights into developing and utilizing novel iron supplements.@*Methods@#Seventy weaning female SPF-graded rats of the SD strain were randomly divided into the control group (A), model group (B), ferrous sulfate group (C), lactoferrin group (D), lactoferrin iron chelate group (E), Casein oligopeptide iron chelate group (F) and whey protein oligopeptide iron chelate group (G), with 10 rats in each group. The rats in group A were fed with normal diet, and the others were fed with poor iron diet for IDA modeling. The corresponding interventions were given by intragastric administration once a day. The iron ion concentrations of group C, E, F and G were 2.0 mg/kg, and the protein and oligopeptide concentrations of group D, E, F and G were 2 000 mg/kg. Body weight and hemoglobin of rats were measured weekly during 21-day intervention. At the end, peripheral blood samples were collected, and blood routine, iron metabolism and liver function indicators were determined. @*Results@#After the intervention, among blood routine indicators, the rats in group C, E, F and G showed elevated hemoglobin, red blood cell, mean corpuscular volume and hematocrit, and decreased free protoporphyrin and mean corpuscular hemoglobin concentration when compared with the rats in group B (all P<0.05); among iron metabolism indicators, the rats in group C, E and G showed elevated serum ferritin, the rats in group C, E, F and G showed elevated serum iron, the rats in group C, D, E, F and G showed decreased unsaturated iron binding capacity and total iron binding capacity when compared with the rats in group B (all P<0.05); among liver function indicators, the rats in group E and G showed decreased alanine transaminase when compared with the rats in group B (both P<0.05). @*Conclusions@#Lactoprotein alone could not completely improve IDA in rats compared with traditional iron supplement (ferrous sulfate). Lactoprotein iron chelate, especially whey protein oligopeptide iron chelate, could significantly improve IDA, iron reserve and liver function damage in rats.

Bone Marrow Adipocytes Promote the Survival of Multiple Myeloma Cells and Up-Regulate Their Chemoresistance / 中国实验血液学杂志

OBJECTIVE@#To investigate the effect of adipocytes in the bone marrow microenvironment of patients with multiple myeloma (MM) on the pathogenesis of MM.@*METHODS@#Bone marrow adipocytes (BMA) in bone marrow smears of health donors (HD) and newly diagnosed MM (ND-MM) patients were evaluated with oil red O staining. The mesenchymal stem cells (MSC) from HD and ND-MM patients were isolated, and in vitro co-culture assay was used to explore the effects of MM cells on the adipogenic differentiation of MSC and the role of BMA in the survival and drug resistance of MM cells. The expression of adipogenic/osteogenic differentiation-related genes PPAR-γ, DLK1, DGAT1, FABP4, FASN and ALP both in MSC and MSC-derived adipocytes was determined with real-time quantitative PCR. The Western blot was employed to detect the expression levels of IL-6, IL-10, SDF-1α, TNF-α and IGF-1 in the supernatant with or without PPAR-γ inhibitor.@*RESULTS@#The results of oil red O staining of bone marrow smears showed that BMA increased significantly in patients of ND-MM compared with the normal control group, and the BMA content was related to the disease status. The content of BMA decreased in the patients with effective chemotherapy. MM cells up-regulated the expression of MSC adipogenic differentiation-related genes PPAR-γ, DLK1, DGAT1, FABP4 and FASN, but the expression of osteogenic differentiation-related gene ALP was significantly down-regulated. This means that the direct consequence of the interaction between MM cells and MSC in the bone marrow microenvironment is to promote the differentiation of MSC into adipocytes at the expense of osteoblasts, and the cytokines detected in supernatant changed. PPAR-γ inhibitor G3335 could partially reverse the release of cytokines by BMA. Those results confirmed that BMA regulated the release of cytokines via PPAR-γ signal, and PPAR-γ inhibitor G3335 could distort PPAR-γ mediated BMA maturation and cytokines release. The increased BMA and related cytokines effectively promoted the proliferation, migration and drug resistance of MM cells.@*CONCLUSION@#The BMA and its associated cytokines are the promoting factors in the survival, proliferation and migration of MM cells. BMA can protect MM cells from drug-induced apoptosis and plays an important role in MM treatment failure and disease progression.

Mechanism of paeoniflorin inhibiting apoptosis of hippocampal neurons of rats induced by lead acetate / 中华劳动卫生职业病杂志

Objective: To investigate the effect and underlying mechanism of paeoniflorin on hippocampal neuron apoptosis induced by lead acetate. Methods: In September 2020, primary hippocampal neuronal cells were isolated and cultured from fetal rats, and identified using cellular immunofluorescent. MTT assay was used to measure the cell viability to determine the concentration and time of lead acetate-induced hippocampal neuron apoptosis. MTT was also used to evaluate the effect of paeoniflorin concentration on the apoptosis of hippocampal neurons induced by lead acetate. According to the results, different concentrations of paeoniflorin were selected to intervene hippocampal neuron cells, after 24 h, lead acetate was added to the cells, meanwhile, blank and model groups were set up, the content of reactive oxygen species (ROS) , superoxide dismutase (SOD) , lactate dehydrogenase (LDH) , malondialdehyde (MDA) and Caspase-3 were measured. Extracellular signal regulated kinase (ERK) , phosphorylated ERK (p-ERK) , p38 mitogen -activated protein kinases (p38MAPK) , phosphorylated p38MAPK (p-p38MAPK) , c-Jun N-terminal kinase (JNK) and phosphorylated JNK (p-JNK) protein expression in hippocampal neuronal cells were determined by Western blotting. Results: The isolated and cultured hippocampal neurons were identified by immunofluorescence chemical staining and then treated with lead acetate, MTT results showed that lead acetate had the best toxicity effect when treated for 24 h at a concentration of 25 μmol/L. Paeoniflorin showed no cytotoxic effect on hippocampal neuronal cells when the concentrations below 80 μmol/L. Compared with the model group, the activity of hippocampal neuronal cells was significantly increased after treating with 20, 40 or 80 μmol/L paeoniflorin (P<0.05) . Compared with the blank group, the ROS activity, LDH release level, MDA content and caspase-3 content were significantly increased (P<0.01) , and the SOD activity was significantly decreased (P< 0.01) in the hippocampal neuronal cells of the model group. Compared with the model group, the ROS activity, LDH release level, MDA content and caspase-3 content were obviously decreased (P<0.05) , SOD activity was significantly increased (P <0.01) after hippocampal neuronal cells were treated with 40 or 80 μmol/L paeoniflorin. Relative to the model group, the ratio of p-ERK/ERK were significantly up-regulated (P<0.01) , while the ratios of p-p38MAPK/p38MAPK and p-JNK/JNK were significantly down-regulated after hippocampal neuronal cells were treated with 40 or 80 μmol/L paeoniflorin (P<0.05) . Conclusion: Paeoniflorin may down-regulate the expression of p-p38MAPK and p-JNK protein, up-regulate the expression of p-ERK protein, and inhibit the apoptosis of hippocampal neurons induced by lead acetate through the MAPK signaling pathway.

An investigation of bacillary dysentery outbreaks in three schools in Ankang / 中国学校卫生

Objective@#To investigate risk factors and epidemiological characteristics of bacillary dysentery outbreaks in three schools, and to provide scientific basis for the prevention and control of the epidemic in the future.@*Methods@#Case definition was established. All suspected, possible and confirmed cases of all students and faculty members from 3 schools (A, B, C) were selected for epidemiological investigation. Control group was used for case-control analysis, and relevant samples were collected for laboratory testing.@*Results@#A total of 132 cases were found in 3 schools, all of which were from students, with the incidence rate of 17.74%. The morbidity in kindergarten A was 20.00%, in center primary school B it was 21.74%, and in junior middle school C it was 11.61%. Cohort studies and casecontrol studies suggested that schools are exposed places and that washing hands with raw water in schools was possible risk factor [OR(95%CI) =4.50(1.01-20.11)]. Nine stool samples were tested in laboratory, among which 8 were positive for Shigella(88.99%), and Shigella was detected in the end nodes of school s pipeline network, the water samples from canteen bucket, and the floor drains of sewer pipe.@*Conclusion@#The bacillary dysentery outbreaks in 3 schools was caused by Shigella, which may be due to fecal contamination of domestic water in 3 schools before the start of the school year. It is suggested to strengthen the management of centralized water supply and construction in rural areas, intensify the supervision at all levels, and sanitation and disinfection before school opens at all levels.

Effect of the Connexin 43 Coupling to the Biobehavior of Multiple Myeloma Cells / 中国实验血液学杂志

OBJECTIVE@#To investigate the effect of gap junction intercellular communication (GJIC) combined by connexin43 (Cx43) and its signal to the biobehavior of multiple myeloma (MM) cells, and its possible mechanism.@*METHODS@#The mesenchymal stem cell (MSC) cells were isolated and cultured from patients with MM and normal donors. The expression of connexin43 (Cx43) in MSC cells from different sources was detected by RT-PCR and Western blot. The side population (SP) cells were sorted by flow cytometry (FCM). The effect of MSC cells from different sources to the cell cycle, Cx43 expression, colony formation in vitro, stem cell related genes expression, cytokines secretion and chemoresistance in MM SP cells as well as with or without Cx43 inhibitor 18α-glycyrrhetinic acid (18α-GA) was observed.@*RESULTS@#There was no significantly difference between the MSC isolated from normal donor and MM patients. Western blot showed that Cx43 expression in SP cells was up-regulated when the cells were incubated with MSC, and medium containing 18α-GA could partially inhibit it, moreover, it was more significant in MSC cells of MM patients. The ability of colony formation of SP cells in vitro was higher than those of MM cells and MM-MSC could promote the colony formation in a co-culture manner. The effect of MM-MSC to SP cells was down-regulated after 18α-GA was added. RT-PCR showed that there was several important stem cell-related genes including c-myc, Oct-4 Klf-4, and Sox-2 were found in RPMI 8226 cells, but those cells were up-regulated in SP cells (P0.05). Cytometry bead array assays showed that MM-MSCs could secrete high level of IL-6, but the levels of IL-6, IL-10 and TGF-β increased significantly when the MM-MSCs were co-cultured with SP cells (P<0.05), especially the levels of IL-6 and IL-10 were significantly higher than cultured alone. There was no significant change in the levels of bFGF and IL-17 before and after co-cultured. The levels of IL-6, IL-10 and TGF-β in supernatant decreased significantly after GJ inhibitor 18α-GA was added. PI/Annexin V assay showed that MM cells were sensitive to bortezomib (BTZ)-induced apoptosis, but the sensitivity for SP cells was weaker. The ratio of cell apoptosis was 75.2%±0.77% and 8.12%±0.86% (P<0.001), respectively. MM-MSC could down-regulate the cell apoptosis induced by BTZ, while the sensitivity of MM cells to BTZ could be partially recovered after GJ inhibitor was added.@*CONCLUSION@#MSC derived from MM patients can enhance GJIC to maintain its "hematopoiesis" by up-regulating the expression of Cx43 in MM cells, and at the same time promote cell proliferation and drug recistance by secreting multiple cytokines, which finally contributes to the relapse of MM.

Comparison between direct factor Xa inhibitors and low-molecular-weight heparin for efficacy and safety in the treatment of cancer-associated venous thromboembolism: A meta-analysis

Aim of the Study: The role of direct-acting oral anticoagulants in the treatment of venous thromboembolism (VTE) in cancer patients compared with the current standard of low-molecular-weight heparin (LMWH) treatment remains unclear. This meta-analysis aimed to evaluate the efficacy and safety of direct factor Xa inhibitors compared with those of LMWH in the treatment of cancer-associated VTE. Materials and Methods: We systematically searched PubMed, EMBASE, Cochrane library, and Web of Science for potential randomized controlled clinical trials and retrospective cohort studies. Data on recurrent VTE (efficacy) and major and minor bleeding events (safety) were extracted, and the odds risks (OR) were analyzed using a random-effect model. Results: A total of nine studies involving 4208 cancer patients with VTE were included in these analyses. Pooled analysis showed that direct factor Xa inhibitors were significantly superior to LMWH in reducing the risk of recurrent VTE (OR = 0.67; 95% confidence interval [CI]: 0.54–0.82). There was no significant difference in the rate of major bleeding between the direct factor Xa inhibitor and LMWH treatments (OR = 1.25; 95% CI: 0.94–1.65). However, the rate of minor bleeding events was higher when a direct factor Xa inhibitor was used instead of LMWH (OR = 1.80; 95% CI: 1.05–3.07). Conclusions: Direct factor Xa inhibitors are superior to LMWH in efficacy in the treatment of VTE in cancer patients, and the safety between the two regimens is comparable except for a slightly higher rate of minor bleeding when the former is used

Analysis of preoperative left ventricular dysfunction and perioperative complications in coronary artery bypass grafting: A case control study / 中国胸心血管外科临床杂志

@#Objective     To identify the relationship between preoperative left ventricular dysfunction and perioperative risk factors in coronary artery bypass grafting (CABG). Methods     The clinical data of 192 patients who underwent CABG from November 2015 to October 2016 were analyzed retrospectively. The patients were divided into three groups by preoperative left ventricular ejection fraction (LVEF) in echocardiography: a serious left ventricular dysfunction group (LVEF≤35%, 23 patients, 15 males and 8 females at age of 63.91±5.36 years), a moderate left ventricular dysfunction group (35%<LVEF<50%, 24 patients, 20 males and 4 females at age of 66.29±6.03 years) and a normal left ventricular function group (LVEF≥50%, 145 patients, 86 males and 59 females at age of 66.60±6.41 years). Results     The overall mortality was 4.16% (8/192), 17.39% (4/23) in patients with LVEF≤35% and 2.76% (4/145) in those with LVEF≥50%. Preoperative LVEF≤35%, hypoxia, assisted circulation, acute kidney injury (AKI) and postoperative continuous renal replacement therapy (CRRT) were risk factors of perioperative mortality in coronary artery surgery. LVEF≤35% and CRRT were independent preditors of mortality. There were significant differences in mortality and postoperative complications between the serious left ventricular dysfunction group and other two groups. Conclusion     Postoperative mortality and complications are obviously serious in the patients with LVEF≤35%. We should pay more attention to preoperative risk factors. Postoperative individual manipulation, intra-aortic balloon pump   and CRRT can enhance survival of those patients.

Compared with the model group, expression levels of IL-5 and eotaxin, the count of EOS, CD34+ cells, CD34+ / CCR3+ were lowered in three treated groups (P < 0.01). Compared with the Western medicine group, the count of EOS and CD34+ / CCR3+ decreased in the combined group (P < 0.01). The count of EOS was significantly lower in the combined group than in the WD group (P < 0.01).</p><p><b>CONCLUSION</b>WD could reduce levels of in vivo inflammatory factors, and restrain the differentiation and recruitment of EOS,thereby alleviating the differentiation of CD34 progenitor cells to EOS.</p>
