ABSTRACT

ObjectiveTo improve the response capabilities to disasters and prevent major epidemics, it is of practical use to study the capability evaluation system of the national emergency medical rescue team that combines theoretical training and practical exercises, to enhance the overall quality of the teams. MethodsFirst, a capability assessment system for the national emergency medical rescue team was constructed based on the INSARAG External Classification (IEC) standards of the national emergency medical rescue team. Then, based on the outcome based education (OBE) concept, we conducted innovative research on the curriculum design and exercise programs for team building and member training. Finally, an empirical analysis was conducted on the effectiveness of the evaluation system and training exercises based on the statistical analysis of the comprehensive quality evaluation of the Shanghai national emergency medical rescue team from 2020 to 2023, as well as the empirical analysis of the rescue exercise on the Cruise of spectrum. ResultsBased on the linear regression analysis of each core competency indicators, the five core competencies in the evaluation system, including rescue skills, medical and health knowledge, disaster coping ability, team cooperation ability, and mental resilience training, were positively correlated with the cumulative number of trainings (r=0.71, r=0.76, r=0.81, r=0.84, r=0.96,all P<0.05), indicating that the training was effective and the course design was reasonable. Empirical cases showed that the three-dimensional rescue drill model had remarkable results in the actual combat application and ability improvement of team members. ConclusionThe training courses and drills designed based on the three-level assessment system are effective in improving the comprehensive capabilities of the national emergency medical rescue team.

ABSTRACT

Objective:To evaluate the role of nuclear factor E2-related factor 2 (Nrf2)/heme oxidase-1 (HO-1) in reduction of renal ischemia-reperfusion (I/R) injury by the human umbilical cord mesenchymal stem cells (hucMSCs)-derived exosomes (hucMSCs-exo) in mice.Methods:The hucMSCs were cultured, and exosomes were extracted and identified by transmission electron microscopy, nanoparticle tracking analysis and Western blot. Thirty-six male SPF-grade C57BL/6 mice, weighing 20-25 g, were used. Thirty mice were selected and divided into 5 groups ( n=6 each) by a random number table method: sham operation group (Sham group), sham operation + Nrf2 inhibitor ML385 group (Sham + ML385 group), renal I/R group (I/R group), renal I/R + exosome group (I/R+ EXO group), and renal I/R + exosome + Nrf2 inhibitor ML385 group (I/R+ EXO+ ML385 group). A model of renal I/R injury was prepared by clamping the bilateral renal pedicles for 45 min followed by perfusion in anesthetized animals. ML385 30 mg/kg was intraperitoneally injected at 45 min before preparing the model in Sham+ ML385 group and I/R+ EXO+ ML385 group, and hucMSCs-exo 100 μg was injected via the tail vein at 15 min before reperfusion in I/R+ EXO group and I/R+ EXO+ ML385 group. Serum blood urea nitrogen (BUN) and creatinine (Cr) concentrations were detected at 24 h of reperfusion. The renal tissues were obtained for examination of the pathological changes and for determination of contents of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) and malondialdehyde (MDA), superoxide dismutase (SOD) activity and reactive oxygen species (ROS) levels and expression of Nrf2 and HO-1 protein and mRNA (by Western blot and quantitative real-time polymerase chain reaction). The left 6 mice were allocated to sham operation group (Sham-IM group, n=3) and renal I/R group (I/R-IM group, n=3) by a random number table method for VISQUE in living imaging observation. Results:The exosomes showed a typical cup-shaped morphology with a transmission electron microscope, the nanoparticles tracked and analyzed the average diameter of the exosome, with an average diameter of 96.7 nm, and the positive expression of surface markers CD9, CD63 and TSG101 was detected using Western blot. The renal fluorescence intensity value was significantly increased in I/R-IM group as compared with Sham-IM group ( P<0.05). Compared with Sham group, the serum BUN and Cr concentrations were significantly increased, the contents of IL-6, TNF-α and MDA and ROS levels were increased, the activity of SOD was decreased, the expression of Nrf2 and HO-1 protein and mRNA was down-regulated ( P<0.05), and the pathological changes of renal tissues were aggravated in I/R group, and no significant change was found in serum BUN and Cr concentrations in Sham+ ML385 group ( P>0.05). Compared with I/R group, the serum BUN and Cr concentrations were significantly decreased, the contents of IL-6, TNF-α and MDA and ROS levels were decreased, the activity of SOD was increased, the expression of Nrf2 and HO-1 protein and mRNA was up-regulated ( P<0.05), and the pathological changes of renal tissues were significantly attenuated in I/R+ EXO group. Compared with I/R+ EXO group, the serum BUN and Cr concentrations were significantly increased, the contents of IL-6, TNF-α and MDA and ROS levels were increased, the activity of SOD was decreased, the expression of Nrf2 and HO-1 protein and mRNA was down-regulated ( P<0.05), and the pathological changes of renal tissues were aggravated in I/R+ EXO+ ML385 group. Conclusions:The mechanism by which hucMSCs-exo reduces renal I/R injury may be related to activation of the Nrf2/HO-1 signaling pathway in mice.

ABSTRACT

In recent years, researchers have found that patients with nonalcoholic fatty liver disease (NAFLD) often have urolithiasis, and the incidence of urolithiasis increases gradually with the severity of NAFLD. Meanwhile, the detection rate of NAFLD was higher in patients with urolithiasis than in normal controls. In this paper, we reviewed the domestic and international studies on the correlation between urolithiasis and NAFLD and described the related pathogenesis, such as insulin resistance, oxidative stress, abnormal lipid metabolism and impaired glyoxalate detoxification. Meanwhile, this paper proposed preventive measures to reduce the risk of development and recurrence of NAFLD-associated urolithiasis by addressing the common risk factors of both diseases, including metabolism-related diseases, lifestyle and diet.

ABSTRACT

Objective To investigate the protective effect of human umbilical cord mesenchymal stem cell-derived exosome (hucMSC-Exo) on renal ischemia-reperfusion injury (IRI), and to clarify the critical role and regulating mechanism of transient receptor potential canonical (TRPC) 6/poly adenosine-diphosphate-ribose polymerase (PARP) 1 signaling pathway during this process. Methods The hucMSC-Exo was extracted by ultracentrifugation, and identified by transmission electron microscope (TEM), nanoparticle tracing analysis and Western blot. SD rats were randomly divided into the sham operation group (group S), sham operation+TRPC6 inhibitor SKF96365 group (group SS), renal IRI group (group IRI), exosome treatment group (group EXO) and exosome +TRPC6 inhibitor SKF96365 group (group ES), with 6 rats in each group. Serum creatinine and blood urea nitrogen levels were detected. Pathological changes of renal tissues were observed by hematoxylin-eosin (HE) staining and Paller score was calculated. The expression levels of key molecules of necroptosis in rat renal tissues, including receptor-interacting protein kinase (RIPK)1, RIPK3 and mixed-lineage kinase domain-like protein (MLKL), TRPC6 and PARP1, were detected by Western blot. Results Typical saucer-like structure was observed under TEM. Nanoparticle tracing analysis showed that the average diameter of the extracted substance was 125.9 nm. Western blot revealed that the surface markers of CD9, CD63 and CD81 were positively expressed, confirmed that the extracted substance was exosome. Compared with group S, the serum creatinine and blood urea nitrogen levels were up-regulated, the pathological damage of renal tissues was worsened, Paller score was elevated, the relative expression levels of TRPC6 and PARP1 proteins were down-regulated, and the relative expression levels of RIPK1, RIPK3 and MLKL proteins were up-regulated in group IRI (all P < 0.05). Compared with group IRI, the serum creatinine and blood urea nitrogen levels were down-regulated, the pathological damage of renal tissues was mitigated, Paller score was decreased, the relative expression levels of TRPC6 and PARP1 proteins were up-regulated, and the relative expression levels of RIPK1, RIPK3 and MLKL proteins were down-regulated in group EXO (all P < 0.05). Compared with group EXO, the serum creatinine and blood urea nitrogen levels were up-regulated, the pathological damage of renal tissues was aggravated, Paller score was increased, the relative expression levels of TRPC6 and PARP1 proteins were down-regulated, and the relative expression levels of RIPK1, RIPK3 and MLKL proteins were up-regulated in group ES (all P < 0.05). Conclusions hucMSC-Exo may alleviate the necroptosis induced by renal IRI in rat models, which is related to the activation of TRPC6/PARP1 signaling pathway.

ABSTRACT

Ischemia-reperfusion injury (IRI) refers to the reperfusion injury caused by the recovery of blood supply of ischemic tissues or organs, which commonly occurs in organ transplantation and other surgical procedures. IRI may cause a series of severe clinical issues, such as delayed graft function, acute kidney injury, myocardial infarction, ischemic stroke and circulatory arrest, etc. These events yield high incidence and fatality. At present, no effective solution has been available. Transient receptor potential canonical 6 (TRPC6), a member of Ca2+ channel family, is highly expressed in multiple types of cells. It may adjust many physiological functions by regulating intracellular Ca2+ concentration, which has become an important target for developing therapeutic drugs for multiple diseases. In this article, research progresses on the introduction and function of TRPC6, the association between TRPC6 and IRI and the therapeutic prospect of TRPC6 targeted drugs in IRI were reviewed, aiming to provide novel insights into the prevention and treatment of IRI during organ transplantation

ABSTRACT

Family physicians contracted service is an important choice to deepen the reform of China′s healthcare reform and achieve the strategic goal of " health for all" . In order to effectively promote the contracted service, the central government has successively issued a number of policy documents, which are echoed by the localities in their proactive explorations, achieving remarkable results. But there are also multiple roadblocks hindering the contracted service to progress. This article referred to the three-circle theory and studied policy implementation from the three dimensions of policy value, policy resources, and policy impetus. A thorough analysis of the problems in the implementation process revealed such main problems as insufficient family physicians, inadequacy of supporting policies and low level of policy acceptance among the young healthy age groups. The follow-up work will promote the long-term implementation of the family physicians contracted service policy by enriching the family physicians team, enriching supporting policies, and focusing on promotions to key age groups.

ABSTRACT

Objective To analyze the dilemmas of our hierarchical medical system, in order to seek a viable path for effective implementation.Methods Based on the Meter-horn model, six related factors were used, including policy standards and goals, policy resources, implementation methods, characteristics of the actuator, value orientation of the executive and the system environment, to analyze the dilemmas of the implementation of hierarchical medical system.Results This policy had not achieved the expected effect in the implementation process, which deviated from the original intention of policy designers to some extent. There exist the following setbacks for the roadblocks. For example, policy standard was ambiguous, the policy resources were insufficient, the execution method was not proper, the implementation mechanism was"criticized" , the implementation personnel value orientation was biased and the complex system environment.Conclusions All the factors involved in the implementation of the hierarchical medical policy affect each other.In this consideration, medical institutions at all levels and the relevant departments should coordinate and deal with the relationship between these six related factors, and timely take effective measures to amend and improve the policy, so as to ensure the orderly progress and long-term implementation of the hierarchical medical system.

ABSTRACT

Objective To investigate the protective role of Sestrin2 overexpression in hypoxia and re-oxygenation injury (H/R) injury of hippocampal neurons and its mechanism in rats.Methods Neurons were enzymatically isolated from hippocampi of newborn Sprague-Dawley rats (less than 24 h old) and culturedinvitro. These neurons were randomly assigned into 4 groups (n=20) using a random number table: control group, H/R group, vector group and Sestrin2 overexpression group. The hippocampal neurons were seeded in 6-well plates at a density of 2×104 cells/mL; neurons in the latter two groups were transfected with lentiviruses containing empty vector andSestrin2overexpressed genes, respectively; the hippocampal neurons in the later three groups were subjected to oxygen-glucose deprivation (OGD) for 6 h followed by restoration of O2 supply for 20 h. The reactive oxygen species (ROS) content was detected by Reactive Species Assay Kit, and the ATP concentration was detected by ATP Assay Kit. Cell apoptosis rates were measured by flow cytometry. The levels of Sestrin2, dynamin-related protein 1 (Drp1), Fis1, and apoptosis-related proteins Bcl-2, Bax and cytochrome C (Cyt C) were measured by Western blotting. The ratio of Bcl-2 to Bax was calculated. The ultrastructure of mitochondria was observed by transmission electron microscopy.Results As compared with control group, H/R group had significantly lower ATP concentration, Bcl-2 protein expression and ratio of Bcl-2 to Bax ([11.15±0.42] nmol/mg proteinvs. [5.30±0.39] nmol/mg protein; 2.20±0.26vs. 0.91±0.02; 6.46± 0.41vs. 1.04±0.05), statistically higher average fluorescence intensity of ROS and cell apoptosis rate (152.41±17.38vs. 1530.00±14.69; 3.77%±0.74%vs. 56.57%±1.35%), and significantly higher protein levels of Sestrin2, Drp1, Fis1, Bax and Cyt C (0.66±0.06vs. 1.11±0.20; 0.48±0.03vs. 1.16±0.07; 1.14± 0.09vs. 2.47±0.09; 0.34±0.03vs. 0.88±0.04; 0.17±0.03vs. 0.30±0.03,P<0.05); what's more, the structure of mitochondria was obviously destroyed in I/R group. As compared with H/R group, Sestrin2 overexpression group had significantly increased ATP concentration, Sestrin2 and Bcl-2 protein expressions and ratio of Bcl-2 to Bax ([8.95±0.27] nmol/mg protein; 2.67±0.07; 1.80±0.19; 3.95±0.28), significantly lower average fluorescence intensity of ROS and cell apoptosis rate (337.27±15.32; 10.33%±2.60%), and statistically lower protein levels of Drp1, Fis1, Bax and Cyt C (0.43±0.02; 1.11±0.08; 0.45± 0.02; 0.17±0.02,P<0.05); the structure of mitochondria was relatively completed in Sestrin2 overexpression group.Conclusion Sestrin2 overexpression can inhibit mitochondrial fission, reduce accumulation of reactive oxygen species, improve mitochondrial energy metabolism and block mitochondria mediated apoptosis pathway, thereby alleviating I/R injury of rat hippocampal neurons.

Objective To investigate the influence of curcumin and its analogue H8 on glucose and lipid metabolism disorder in db/db mice. Methods The type 2 diabetes mouse model (db/db mice) was intragastrically administrated with curcumin and analogue H8 for 8 weeks.The blood biochemical indexes were measured.The expression of PEPCK and G6Pase mRNA was detected by real-time PCR in liver tissues.The expression of PEPCK and G6Pase protein was detected by Western blotting. Results Curcumin analogue H8 reduced blood glucose and lipids in db/db mice (P<0.01) and improved liver function related enzymes significantly.The levels of PEPCK and G6Pase mRNA in db/db mice were significantly decreased (P<0.01) and the expression levels of PEPCK and G6Pase protein were significantly decreased(P<0.01). Conclusion Curcumin analogue H8 improves the glucose and lipid metabolism disorder in db/db mice,and it is related to inhibiting the expression of PEPCK and G6Pase gene and protein.
