Objective To explore the application effects of a discharge planning service program based on King's Goal Attainment Theory in patients undergoing transcatheter heart valve surgery.Methods Using convenience sampling method,80 patients who underwent transcatheter heart valve surgery at a tertiary comprehensive hospital in Zhejiang Province from August 2023 to January 2024 were selected as the research subjects.Among them,40 patients from November 2023 to January 2024 were selected as an experimental group.A discharge preparation service plan for patients undergoing transcatheter heart valve surgery based on King's Goal Attainment Theory was adopted.Totally 40 patients who underwent transcatheter heart valve surgery from August to October 2023 were selected as a control group and underwent routine measures for discharge preparation.The differences in the scores of the discharge preparation scale,discharge guidance quality scale,self-management scale for patients after mechanical heart valve replacement surgery,and unplanned readmission rate were compared between 2 groups before and after intervention.Results During the application of the plan,a total of 2 cases were excluded,and 38 cases were included in the experimental group and 40 cases were included in the control group.After intervention,the experimental group had higher scores in discharge readiness,discharge guidance quality,and self-management ability than the control group,and the differences were statistically significant(P＜0.001).The unplanned readmission rate within 30 days in the experimental group(2.63％)was lower than that in the control group(7.50％),and the difference was not statistically significant(P＞0.05).Conclusion The discharge preparation service plan for patients undergoing transcatheter heart valve surgery based on King's Goal Attainment Theory can improve the discharge preparation,discharge guidance quality,and self-management ability of patients undergoing transcatheter heart valve surgery,and has a positive effect on improving their quality of life.

Objective:To relate the changes in electroencephalography (EEG) signals after a spinal cord injury (SCI) with functional independence.Methods:The EEG data describing ninety SCI patients in both open and closed eye states were compared with those collected from 45 healthy counterparts. The SCI patients′ EEG data were correlated with their spinal cord independence measure (SCIM) scores at corresponding time points. The SCI patients were divided into a cervical SCI group (SCI-C group) and a non-cervical SCI group (SCI-NC group), with 45 cases in each group. The difference in EEG data between them and its correlation with the SCIM scores were also compared and analyzed.Results:In the eyes-open state, the EEG power in the frontal, central, temporal, and right occipital regions of the SCI group was lower than among the control group, on average. There were significant differences in the δ and θ low-frequency bands. The α1 band power in the frontal and right parietal regions was significantly higher in the SCI group, on average. With the eyes closed the δ band power in the right prefrontal, frontal, left central, and temporal regions of the SCI group was lower than among the control group, while the α1 band power in the right prefrontal, frontal, central, and parietal regions was significantly higher. The reactivity to eye opening of the α1 band in the right prefrontal, frontal, central, parietal, and temporal regions was less in the SCI patients compared to healthy subjects. Among the SCI patients, higher EEG power in the β2 band of the right frontal lobe and the α2 and β bands of the right temporal lobe was significantly positively correlated with higher SCIM scores during the eyes-open measurements. And the higher EEG power in the α2 band of the prefrontal and frontal lobes, the β2 band of the frontal lobe, the α2 band of the right central region, the α2 and β bands of the temporal lobe, and the α2 and β2 bands of the occipital lobe was significantly positively correlated with higher SCIM scores during the eyes-closed state. The subgroup analysis showed that the δ band power in the left temporal lobe and the α2 band power in the parietal lobe were lower among the SCI-C compared with the SCI-NC patients in the eyes-open state. With the eyes closed, the δ band power in the left frontal, left parietal, and left temporal lobes and the α2 band power in the frontal, central, parietal, temporal, and right occipital lobes was significantly lower in the SCI-C group compared to the SCI-NC group, on average. The reactivity to eye opening of the δ band in the temporal lobe, the α2 band in the left prefrontal, frontal, central, parietal, temporal, and right occipital lobes, and the β2 band in the right parietal and left occipital lobes was less in the SCI-C group than in the SCI-NC group ( P≤0.05). Among the SCI-C patients, higher EEG power in the β1 and β2 bands of the right temporal lobe with the eyes open was significantly positively correlated with higher SCIM scores. With the eyes closed, higher EEG power in the α2 and β1 bands of the right prefrontal lobe was significantly positively correlated with higher SCIM scores. Among the SCI-NC patients, higher EEG power in the δ band of the prefrontal lobe, the β1 and β2 bands of the left prefrontal lobe, and the δ bands of the frontal, central, right parietal, and right temporal lobes during the eyes open measurements was significantly positively correlated with higher SCIM scores. Conclusions:The EEG power of cervical and non-cervical SCI patients shows characteristic changes which correlate with their functional independence.

Objective:To develop a training content framework for hospice volunteers based on the competency model.Methods:This was a qualitative study. A draft of the training content framwork for hospice volunteers was first formed according to results of literature review and qualitative interviews based on the competency model. From December 2023 to March 2024, two rounds of Delphi consultation with 16 experts were conducted to develop the final version of the system, and the weights of each indicator were determined with analytic hierarchy process.Results:Among the 14 consulting experts who completed two rounds of consultation, including 10 females, all held intermediate or above professional titles, and their working years ranged from 10 to 34 years, covering fields of hospice care, nursing management, clinical nursing and nursing education. In two rounds of consultation the expert positive coefficient was 14/16 and 14/14, the expert authority coefficient was 0.882 and 0.893, and the Kendall coordination coefficient of all indicators was 0.109 and 0.161 ( P<0.01), the coefficient of variation was 0-0.31 and 0-0.19, respectively. The final version of the system consisted of 3 first-level indicators, 7 second-level indicators, 20 third-level indicators, and 55 specific training contents. The three first-level indicators were knowledge, skill, role and value, and the weight coefficients were 0.335, 0.313 and 0.352, respectively. Each judgment matrix was consistent. Conclusions:A training content system for hospice care volunteers has been developed in this study, which may be used for medical institutions and organizations to train hospice care volunteers.

Objective:To investigate the effect of triply periodic minimal surfaces (TPMS) structure and ceramic volume fraction on the mechanical properties of polymer-infiltrated ceramic network (PICN) composite and reveal its strengthening and toughening mechanism.Methods:In this study, TPMS structures with gyroid (G), primitive (P), diamond (D), and ceramic volume fraction (40%, 55%, 70%, 85%) were designed. Porous zirconia scaffolds were prepared using stereolithography technology, and resin was infiltrated into the scaffolds through a vacuum. Then, the PICN composites were obtained after curing. The bending strength, elastic modulus and fracture toughness of PICN were tested using an electronic universal testing machine, with commercial PICN as the control group. The micromorphology of PICN was observed through stereomicroscope and scanning electron microscope. The cytocompatibility of PICN was verified by using cell counting kit, live/dead cell staining and phalloidin staining.Results:The bending strength values of PICN with different ceramic volume fractions ranged from 82.0 MPa to 376.0 MPa, and they gradually increased as the ceramic volume fraction rised. The elastic modulus values of PICN with different ceramic volume fractions ranged from 12.1 GPa to 56.1 GPa. The fracture toughness values of PICN with different ceramic volume fractions ranged from 1.7 MPa·m 1/2 to 6.5 MPa·m 1/2. The bending strength of 85G PICN reached 306.0 MPa, and it had the highest fracture toughness (6.5 MPa·m 1/2) and an appropriate elastic modulus between that of the control group and that of enamel. Under scanning electron microscopy, it could be observed that the cracks branch and deflect at the interface and eventually terminate within the resin phase. After co-culture with PICN, the survival rate of mouse fibroblasts exceeded 80%, indicating that PICN had no cytotoxicity. Conclusions:The PICN composite with TPMS structure can satisfy the mechanical properties and cytocompatibility of dental prosthesis.

Objective To investigate the value of early maternal serological indicators in predic-ting the delivery of full-term small-for-gestational-age(SGA)infants.Methods The clinical data of pregnant women who delivered at Beijing Tongzhou District Maternal and Child Health Hospital from August 2023 to August 2024 were analyzed.A total of 180 pregnant women who delivered full-term SGA infants were included in case group,and 180 pregnant women who delivered full-term appropri-ate-for-gestational-age(AGA)infants during the same period were included in control group.The levels of serum pregnancy-associated plasma protein A(PAPP-A),placenta growth factor(PLGF),and soluble fms-like tyrosine kinase-1(sFlt-1)in the first trimester(11 to 13 weeks+6 days of ges-tation)of the two groups were compared.Receiver operating characteristic(ROC)curves were used to analyze the predictive value of early maternal serological indicators for the delivery of full-term SGA infants.Results The levels of serum PAPP-A and PLGF in the first trimester of the case group were lower than those in the control group,while the level of sFlt-1 was higher(P＜0.05).The area un-der the ROC curve(AUC)for the combined detection of serum PAPP-A,PLGF,and sFlt-1 levels in the first trimester in predicting the delivery of full-term SGA infants was 0.823,which was higher than the AUCs for detection of each indicator(0.738,0.720,0.724)(P＜0.05).Conclusion The detection of early maternal PAPP-A,PLGF,and sFlt-1 levels can reflect the fetal growth status in utero.The combined detection of these three indicators has a higher predictive value for the delivery of full-term SGA infants by pregnant women,which is helpful for clinicians to take intervention measures in advance.

Objective To establish a portable gas chromatography-mass spectrometry (GC-MS) method for determining carbon disulfide in workplace air. Methods Samples were collected using the built-in Tenax GR adsorption tube in the portable GC-MS, followed by thermal desorption. The analytes were separated on a DB-1 chromatographic column and detected by a 3D ion trap mass spectrometer, with 1,3,5-tris(trifluoromethyl)benzene used as the internal standard. Qualitative analysis was based on retention time and characteristic ions, and quantitative analysis was performed using the internal standard method. Results The method showed a linear range of 0.034-0.340 mg/m³ with a correlation coefficient of 0.999 4 using the adsorption tube enrichment mode. The detection limit was 0.007 mg/m³, and the lower limit of quantification was 0.022 mg/m³. The average recovery ranged from 97.5% to 104.0%. The within-run and between-run relative standard deviation was 2.7%-10.4% and 8.8%-14.8%, respectively. Conclusion A rapid, green, highly sensitive, and interference-resistant on-site detection method was established. As a supplement to existing national standard methods, this method is suitable for real-time monitoring of carbon disulfide in workplace air and for occupational exposure risk assessment.
