OBJECTIVE To analyze the traditional Chinese medicine （TCM） emergency management policy texts in China， reveal the characteristics， problems and improvement directions of Chinese medicine emergency management policies in China， and provide references and lessons for improving the level of Chinese medicine emergency management. METHODS Twenty-four TCM emergency management policy texts issued at the central level from 2016 to 2023 were coded and analyzed using Nvivo11 software to construct a three-dimensional analysis framework based on policy tools， stakeholders and policy strength. RESULTS In the policy tools dimension， the environmental type was the most （46.74%）， the supply type was the second （31.80%）， and the demand type was the least （21.46%）； in the stakeholder dimension， there were more healthcare institutions （40.63%） and government departments （31.25%）， and fewer healthcare workers （14.84%） and residents （13.28%）； in the policy strength dimension， the overall policy strength was poor， and the differences in effectiveness across policy instruments and stakeholders were more significant. The cross-cutting results showed that there was a certain degree of mismatch in policy instruments， stakeholders and policy strength. CONCLUSIONS The use of supply-oriented policy tools is slightly lacking， and the use of policy tools should be optimized in a coordinated manner； the distribution of stakeholders is relatively unbalanced， and synergies among stakeholders should be enhanced； the overall strength of policies is poor， and the top-level design of relevant policies should be improved.

AIM:To investigate the regulatory role of retinoid X receptor(RXR)in oxidative stress response of rat type Ⅱ alveolar epithelial cells(AECII)induced by hypoxia/reoxygenation(HR).METHODS:The AECII were di-vided into control(C)group,HR group,HR+solvent dimethyl sulfoxide(DMSO)group(HD group),HR+RXR agonist 9-cis-retinoic acid(9-RA)group(RA group),and HR+RXR antagonist HX531 group(HX group).Cell Counting Kit-8(CCK-8)method was used to measure the cell viability.Immunofluorescence staining was used to detect the expression of surfactant protein A(SP-A)and RXRα in AECII.Kits were detected to the levels of superoxide dismutase(SOD)and malondialdehyde(MDA)in cells.Transmission electron microscopy was used to observe the ultrastructural changes of the cells.Western blot was used to detect the protein level of nuclear factor E2-related factor 2(Nrf2).RT-PCR was used to detect the expression level of Nrf2 mRNA.RESULTS:Compared with C group,the cell viability and SOD activity in HR,HD,RA and HX groups were decreased significantly(P<0.05),the MDA content were increased significantly(P<0.05),the Nrf2 mRNA and protein expression levels were decreased significantly(P<0.05 or P<0.01),and the immuno-fluorescence expression of RXRα was significantly increased(P<0.01).Compared with HR and HX groups,the cells in RA group showed significantly increased cell viability(P<0.05),increased SOD activity(P<0.05),decreased MDA con-tent(P<0.05),increased Nrf2 mRNA and protein expression levels(P<0.01),and significantly increased immunofluo-rescence expression of RXRα(P<0.01).CONCLUSION:Hypoxia/reoxygenation can aggravate the oxidative stress re-sponse of rat AECII,and RXR agonist intervention can alleviate HR-induced rat AECII injury by inhibiting oxidative stress.

Objective To investigate the utility of dual-energy CT combined with musculoskeletal ultraso-nography in differentiating between calcium pyrophosphate deposition disease and gouty arthritis.Methods A retro-spective analysis was conducted on the medical records of 102 patients diagnosed with gouty arthritis and 102 patients diagnosed with calcium pyrophosphate deposition disease.These patients were categorized into the Gout group and Calcium Deposition group,respectively,based on their respective diagnoses.All patients underwent dual-energy CT and musculoskeletal ultrasonography examinations,while joint fluid aspiration results or intra-articular crystal material served as the gold standard for diagnosis.The diagnostic efficacy of dual-energy CT and musculoskeletal ultrasonography in discriminating between calcium pyrophosphate deposition disease and gouty arthritis was evalu-ated.Results In the gout group,the proportion of male patients and serum uric acid levels were significantly higher compared to those in the calcium deposition group(P<0.05).The prevalence rates of knee joint,first metatarsopha-langeal joint,and ankle joint involvement were higher in the gout group,while knee joint,wrist joint,and shoulder joint involvement rates were higher in the calcium deposition group.The proportions of irregular bone cortex,carti-lage injury,and degenerative meniscus changes were lower in the gout group compared to the calcium deposition group(P<0.05).The proportions of double contour sign,tophus formation,hyperechoic band within ligaments or tendons,and bone erosion were higher in the gout group compared to the calcium deposition group(P<0.05),whereas cartilage calcification was lower in the gout group(P<0.05).The sensitivities for diagnosing calcium pyrophosphate deposition disease and gouty arthritis using dual-energy CT scan alone,musculoskeletal ultrasound alone,and their combined use were 86.27%,83.33%,and 94.12%respectively.The specificities for diagnosing these conditions using dual-energy CT scan alone,musculoskeletal ultrasound alone,and their combined use were 89.22%,88.24%,and 86.27%respectively.The positive predictive values were 88.89%,87.63%,and 87.27%,respectively.The negative predictive values were 86.67%,84.11%,and 93.63%,respectively.The accuracies were 87.75%,85.78%,and 90.20%respectively.The agreement Kappa values were 0.755,0.716,and 0.804 respectively.Conclusions The integration of dual-energy CT and musculoskeletal ultrasonography exhibits promising diagnostic efficacy in discriminating between calcium pyrophosphate deposition disease and gouty arthritis.This combined approach serves as a valuable adjunctive tool for the diagnosis of both conditions.

AIM:To investigate the effects of sodium hydrosulfide(NaHS)on hexokinase 2(HK2)-nucleo-tide-binding oligomerization domain-like receptor protein 3(NLRP3)-gasdermin D(GSDMD)pathway and pyroptosis in-duced by lung ischemia/reperfusion(I/R)in rats.METHODS:Male Sprague-Dawley rats were divided into 6 groups:control group,control+NaHS group,I/R group,low-dose NaHS+I/R(L+I/R)group,medium-dose NaHS+I/R(M+I/R)group,and high-dose NaHS+I/R(H+I/R)group,with 6 rats in each group.The NaHS was administered via intraperi-toneal injection at 1.5 mL,30 min before modeling.The left lung tissues were collected 30 min after ischemia and 1 h af-ter reperfusion,and the wet/dry weight ratio and total lung water content were recorded.Hematoxylin-eosin(HE)staining was used to examine lung tissue morphological changes.The levels of malondialdehyde(MDA),myeloperoxidase(MPO)and lactate in lung tissues were measured with test kits.ELISA was employed to determine the levels of interleukin-1β(IL-1β)and IL-18.The expression of glycolysis-and pyroptosis-related indicators was analyzed by Western blot,qRT-PCR and immunofluorescence staining.RESULTS:Compared with control group,the rats in NaHS group showed no signifi-cant differences in all laboratory tests(P>0.05).The rats in I/R group exhibited significant lung injury,oxidative stress,increased lactate level,and up-regulated glycolysis and pyroptosis(P<0.05 or P<0.01).Compared with I/R group,the indicators in L+I/R group showed a downward trend(P<0.01)or no difference(P>0.05),while those in M+I/R group dis-played a significant reduction(P<0.05 or P<0.01).However,the indexes in H+I/R group exhibited no significant dif-ferences in these tests(all P>0.05).CONCLUSION:A moderate dose(56 μmol·L-1·kg-1)of NaHS mitigated the oc-currence of pyroptosis by inhibiting the HK2-NLRP3-GSDMD pathway,thus contributing to the attenuation of lung I/R in-jury in rats.

Purpose: This study investigated whether professional identity predicts learning burnout among Chinese nursing students, and whether resilience moderates this relationship. Methods: This cross-sectional study recruited 635 students from a nursing college at a medical university in Hefei, China. Data were collected using the professional identity questionnaire, learning burnout scale for college students, and 10-item Connor-Davidson Resilience Scale. Pearson’s correlation analysis was used to investigate the relationships between variables. The mediation effect was evaluated using linear regression and the bootstrap method in SPSS. Results: Nursing students exhibited intermediate learning burnout levels (score: 54.95 ± 10.42). Professional identity was positively correlated with psychological resilience (r = .42, p < .001), whereas learning burnout was negatively correlated with professional identity (r = - .54, p < .001) and psychological resilience (r = -.57, p < .001). Psychological resilience mediated the relationship between professional identity and learning burntout to the tune of 32.8%. Conclusion Psychological resilience mediates the relationship between professional identity and learning burnout. Thus, nursing educators can mitigate student burnout by developing their students' professional identities and psychological resilience.
