Annual financial expenditure in 24 domestic blood stations: a comparative analysis / 中国输血杂志

【Objective】 To study the annual financial expenditure in blood stations with different scales, and to establish the regression equation between blood collection units and total expenditure. 【Methods】 The annual total expenditure, the per capita cost of serving population, as well as the collection units of whole blood and apheresis platelet of 24 blood stations were collected. The financial expenditure required for collecting 10 000U blood was calculated.The statistical analysis was carried out with SPSS statistical software. 【Results】 From 2017 to 2020, the total annual financial expenditure of 24 blood stations showed an upward trend. The total expenditure among blood stations was different. The per capita cost of servicing population in the areas where the 24 blood stations were located had been increasing year by year. The 24 blood stations were divided into two grades according to the blood collection volume as 50 000 U, and the relationship equation between the blood collection volume and the annual total expenditure had been established. After testing, each equation was effective(P<0.05); There was no difference in the financial expenditure required for collecting 10 000U blood among blood stations with different scales. 【Conclusion】 From 2017 to 2020, the blood stations with an annual collection volume more than 50 000 U demonstrated a higher financial expenditure and the per capita cost of serving population than those <50 000 U. The blood collection volume of blood stations is significantly correlated with the annual total expenditure and the per capita cost of serving population.

Generation of induced pluripotent stem cell GZHMCi002-A from peripheral blood mononuclear cells with APOB mutation.

Apolipoprotein (apo) B is a large, amphipathic glycoprotein which plays an important role in human lipoprotein metabolism. The 43-kb APOB gene located on the short arm of human chromosome 2 and consisted of 29 exons, mutations in the APOB gene can give rise to either hypo- or hypercholesterolemia. We used peripheral blood mononuclear cells (PBMCs) from a volunteer carrying the APOB mutation (c.10579C>T, p.Arg3527Trp) located in exon 9 to establish induced pluripotent stem cells (iPSC), which will be an effective means to reveal the key biologically relevant metabolic mechanisms, a powerful tool for medicine selection and related research.

Abstract Based on the concept of doctor's moral hazard behavior and the theoretical model of planned behavior, this paper constructs a theoretical model of doctor's moral hazard behaviorm and analyzes the main influencing factors of doctor's moral hazard behavior in detail, including behavioral attitudes, subjective norms and perceived behavioral control. Combined with the results of questionnaire survey, this paper uses structural equation model and factor analysis to verify the hypotheses. The results show that in the theoretical model of doctor's moral hazard behavior, doctors' moral risk intentions are affected by three independent variables: behavioral attitudes, subjective norms and perceived behavioral control. As an intermediary variable, moral risk intentions have a mediating effect on doctors' moral hazard behavior. All path coefficients meet the requirements, and all assumptions of the model are verified. The theoretical model of doctor's moral hazard behavior established in this study can effectively explain the occurrence law of doctor's moral hazard behavior and can predict doctor's moral hazard behavior according to the actual situation of various influencing factors. This provides an effective theoretical guidance for the next step to better carry out the relevant research on doctor's moral hazard based on the management perspective, especially the establishment of prevention and control strategies for doctor's moral hazard behavior.

Generation of induced pluripotent stem cell GZHMCi001-A and GZHMCi001-B derived from peripheral blood mononuclear cells of epileptic patients with KCNC1 mutation.

Myoclonus Epilepsy and Ataxia due to Potassium channel mutation (MEAK) is a rare epilepsy caused by changes in the structure and function of potassium channels due to mutations in the potassium voltage-gated channel subfamily C member 1 (KCNC1) gene. MEAK is one of the progressive myoclonus epilepsy (PME), and there are few studies on MEAK pathogenesis and targeted drugs. Here, we used peripheral blood from MEAK patients with KCNC1 (c.959G > A) gene mutation to establish induced pluripotent stem cells (iPSC). The iPSC of KCNC1 mutation established by us is a powerful tool for related research.

Pathogenesis and multidisciplinary management of medication-related osteonecrosis of the jaw / 国际口腔科学杂志·英文版

Medication-related osteonecrosis of the jaw (MRONJ) is a serious side effect of bone-modifying agents and inhibits angiogenesis agents. Although the pathogenesis of MRONJ is not entirely clear, multiple factors may be involved in specific microenvironments. The TGF-β1 signalling pathway may have a key role in the development of MRONJ. According to the clinical stage, multiple variables should be considered when selecting the most appropriate treatment. Therefore, the prevention and management of treatment of MRONJ should be conducted in patient-centred multidisciplinary team collaborative networks with oncologists, dentists and dental specialists. This would comprise a closed responsibility treatment loop with all benefits directed to the patient. Thus, in the present review, we aimed to summarise the pathogenesis, risk factors, imaging features, clinical staging, therapeutic methods, prevention and treatment strategies associated with MRONJ, which may provide a reference that can inform preventive strategies and improve the quality of life for patients in the future.

PEP06 polypeptide 30 is a novel cluster-dissociating agent inhibiting v integrin/FAK/Src signaling in oral squamous cell carcinoma cells

Collectively migrating tumor cells have been recently implicated in enhanced metastasis of epithelial malignancies. In oral squamous cell carcinoma (OSCC), v integrin is a crucial mediator of multicellular clustering and collective movement ; however, its contribution to metastatic spread remains to be addressed. According to the emerging therapeutic concept, dissociation of tumor clusters into single cells could significantly suppress metastasis-seeding ability of carcinomas. This study aimed to investigate the anti-OSCC potential of novel endostatin-derived polypeptide PEP06 as a cluster-dissociating therapeutic agent . Firstly, we found marked enrichment of v integrin in collectively invading multicellular clusters in human OSCCs. Our study revealed that metastatic progression of OSCC was associated with augmented immunostaining of v integrin in cancerous lesions. Following PEP06 treatment, cell clustering on fibronectin, migration, multicellular aggregation, anchorage-independent survival and colony formation of OSCC were significantly inhibited. Moreover, PEP06 suppressed v integrin/FAK/Src signaling in OSCC cells. PEP06-induced loss of active Src and E-cadherin from cell-cell contacts contributed to diminished collective migration of OSCC . Overall, these results suggest that PEP06 polypeptide 30 inhibiting v integrin/FAK/Src signaling and disrupting E-cadherin-based intercellular junctions possesses anti-metastatic potential in OSCC by acting as a cluster-dissociating therapeutic agent.

TNF-alpha stimulation increases dental pulp stem cell migration in vitro through integrin alpha-6 subunit upregulation.

OBJECTIVE: The dissemination of stem cells into tissues requiring inflammatory and reparative response is fundamentally dependent upon their chemotactic migration. Expression of TNF-α is up regulated in inflamed pulps. Dental pulp cells are also known to express integrin α6 subunit. Expression of integrin subunit α6 has been linked to the acquisition of migratory potential in a wide variety of cell types in both pathological and physiological capacities. Therefore, in this study we examined the effects of a pleiotropic cytokine TNF-α on the migration of hDPSCs and investigated its relationship with expression of integrin α6 in hDPSCs during chemotactic migration. DESIGN: hDPSC cultures were established. Protein expression profile of α6 integrin subunit was determined. Effect of exogenous TNF-α (50ng/mL) on hDPSCs' migration potential was evaluated by transwell inserts and in vitro scratch assay. Upregulation/downregulation of TNF-α mediated migration was assayed in presence/absence of integrin α6 respectively. To suppress integrin α6 expression, cells were transfected with integrin α6 siRNA and then cell migration and cytoskeletal changes were evaluated. RESULTS: Our results showed significant increase of hDPSCs' migration after stimulation with TNF-α. By knockdown of integrin α6, which is upregulated by TNF-α, we observed a decrease in the TNF-α directed chemotaxis of hDPSCs. CONCLUSION: In this study, we show that activation of integrin α6 brought about by TNF-α led to an increase in migratory activity in DPSCs in vitro thus describing a novel association between a cytokine TNF-α and α6 chain of an adhesion receptor integrin in regulating migration of hDPSCs.
