ObjectiveTo explore the driving forces for oncology nurses’ participation in palliative care work, thereby providing a theoretical basis for the improvement of education and training, incentive mechanisms, and other aspects of the palliative care nursing staff. MethodsEmploying a qualitative research method, semi-structured interviews lasting 40-60 minutes were conducted with 14 nurses who had participated in palliative care work. The interview data were analyzed using the Colaizzi seven-step analysis method. ResultsInternal positive driving forces were job interest, empathy, and a sense of professional responsibility, while the negative was low psychological resilience. External positive driving forces included high work support, professional identity, mutual benefits for nurses and patients, and positive patient attitudes, whereas negative driving forces comprised busy routine clinical work, lack of a reward and incentive system, and bland or negative patient attitudes. ConclusionIt is essential to provide a flexible platform for the enhancement of nurses’ professional capabilities in palliative care, intensify the publicity of palliative care and death education; intervene and guide nurses’ negative emotions, improve and implement relevant incentive systems, and standardize the job recognition and scope of responsibilities of palliative care nurses.

ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ(CaMKⅡ)/cAMP-response element binding protein (CREB) signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet, intraperitoneal injection of isoproterenol (ISO), and chronic unpredictable mild stress (CUMS). A total of 108 SD male rats were randomly divided into normal group, model group, high (23.4 g·kg-1), medium (11.7 g·kg-1), and low (5.85 g·kg-1) dose groups of modified Chaihu Shugansan, CaMKⅡ inhibitor (KN93) group, and KN93 + high, medium, and low dose groups of modified Chaihu Shugansan, with 12 rats in each group. From the first day of modeling to the end of modeling, drugs were administered once a day. In the seventh and eighth weeks, the KN93 group and the KN93 + high, medium, and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week, behavioral tests including sucrose preference, open field, and elevated plus maze were conducted. Electrocardiogram (ECG) lead Ⅱ changes were observed in each group of rats, and hematoxylin-eosin (HE) staining was performed to observe changes in heart tissue. Serum levels of triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and lactate dehydrogenase (LDH) were measured by using an enzyme-labeled instrument. Creatine kinase (CK) and creatine kinase-MB (CK-MB) were detected by ultraviolet spectrophotometry, while serum monocyte chemoattractant protein-1 (MCP-1) was measured by enzyme-linked immunosorbent assay (ELISA). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue, and Western blot was performed to assess protein expression of CaMKⅡ, phosphorylated (p)-CaMKⅡ, CREB, and p-CREB. ResultsCompared to the normal group, the model group showed significant reductions in sucrose preference rate, total activity distance in the open field, number of entries into the center area of the open field, and percentage of entries into the open arms of the elevated plus maze (P<0.01). The ECG showed ST-segment elevation, and HE staining showed serious degeneration of myocardial fibers, disordered arrangement, and infiltration of a large number of inflammatory cells. In addition, serum TC and LDL levels increased (P<0.01), and HDL level decreased (P<0.01). CK, CK-MB, LDH, and MCP-1 levels significantly increased (P<0.05, P<0.01). The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue (P<0.05, P<0.01), but those increased in the heart tissue (P<0.01). Compared to the model group, the high, medium, and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference, total activity distance in the open field, number of entries into the center area of the open field, and percentage of entries into the open arms of the elevated plus maze (P<0.01), as well as decreased serum CK, CK-MB, LDH, and MCP-1 levels (P<0.05, P<0.01). KN93 also reduced ST-segment elevation, alleviated the degeneration degree of myocardial fibrosis, and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced (P<0.05, P<0.01). The KN93 + high, medium, and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression, possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway, with the high-dose modified Chaihu Shugansan showing the best effects.

Objective To design and synthesize dual-target antidepressant compounds possessing high-affinity binding to the serotonin 1A receptor(5-HT1A)and dual-site synergistic inhibition of the serotonin transporter(SERT).Methods Based on a dual-target synergistic mechanism,benzodioxolane derivatives were designed via scaffold hopping strategy before being synthesized.Their binding affinities to both targets were determined via competitive radioligand binding assays,and their binding modes were investigated using molecular docking.Results Eleven structurally novel target compounds were synthesized and structurally characterized by electrospray ionization mass spectrometry(ESI-MS)and nuclear magnetic resonance(NMR)spectroscopy.Compound 18b demonstrated dual nanomolar affinity for both the 5-HT1A receptor(Ki=2.72 nmol/L)and SERT(Ki=8.85 nmol/L).Molecular docking revealed that its inhibitory effect on SERT resulted from simultaneous occupation of the orthosteric site S1(Asp98 salt bridge)and the allosteric site S2(Arg104 rr-cation interaction),while its high affinity for 5-HT1A depended on the Asp116332 salt bridge anchor and π-π stacking with Phe362652.Conclusion The benzodioxolane-scaffold compounds designed and synthesized in this study exhibited functional synergy between simultaneous occupation of both the S1 and S2 sites of SERT and high-affinity binding to the 5-HT1Areceptor.Among them,compound 18b demonstrates superior activity and promises to be a lead compound for more investigation.

This article reported a case of autosomal dominant intellectual developmental disorder type 22 caused by a heterozygous mutation in the ZBTB18 gene. At 24 +4 weeks of gestation, prenatal ultrasound indicated a short outer diameter of the fetal corpus callosum and bilateral ventricular dilatation. Whole-genome copy number variation analysis of the fetus showed no abnormalities. Whole exome sequencing (WES) and Sanger sequencing validation of the family revealed the fetus carried a c.1374_1383del(p.S459*) heterozygous mutation in the ZBTB18 gene (NM_205768.3), which was neither phenotypically present nor genotypically detected in the parents, suggesting a de novo mutation. Based on the clinical manifestations, the fetus was diagnosed with autosomal dominant intellectual developmental disorder type 22. After genetic counseling, the pregnant woman opted for termination of the pregnancy. This case highlights the correlation between prenatal ultrasonic detection of callosal dysgenesis and lateral ventricular enlargement and intellectual developmental disorders caused by gene mutations. Furthermore, it expands the mutation spectrum of the ZBTB18 gene, thereby facilitating prenatal diagnosis and genetic counseling.

To explore the correlation between the level of serum interleukin-6 (IL-6) and the severity of infection in patients with diabetic foot (DF) and the auxiliary value of IL-6 in DF diagnosis, and aim to provide reference for clinical treatment. Based on the hospital medical record system and the laboratory system, a retrospective analysis with case-control study was conducted on the data of patients in Liyuan Hospital affiliated to Tongji Medical College, Huazhong University of Science and Technology from January 2020 to September 2024. A total of 377 patients′ information was collected, including 31 cases in control group with 17 males and 14 females from 31 to 91 years old and a median age of 71, 63 cases in NDF group with 43 males and 20 females from 37 to 96 years old, with a median age of 71, and 283 patients in DF group with 197 males and 86 females from 36 to 96 years, with a median age of 67. According to classification of infection severity, paints in the group of diabetes with DF were divided into mild infection subgroup (72 cases), moderate infection subgroup (143 cases) and severe infection subgroup (68 cases). The results showed that there were no statistically significant differences in age and gender among the three groups in the study ( F=1.795/ χ 2=2.81, P>0.05). The non parametric test results showed that there were statistically significant differences in IL-6, C-reactive protein (CRP), procalcitonin (PCT), white blood cell (WBC) and glucose (GLU) among the three groups of patients ( H=12.480, 36.277, 12.432, 12.838, 18.334, P<0.05). The pairwise comparison results showed that compared with the control group, the NDF group had higher levels of CRP, PCT and GLU ( H=20.259, 20.118, 20.056, P<0.05), and the levels of IL-6, CRP, PCT and WBC( H=14.934,14.933,14.829,14.934, P<0.05) were higher in the DF group. Both of the differences were statistically significant. But the difference of IL-6, CRP, PCT, WBC and GLU between the NDF and DF group was not statistically significant( H=1.202,0.622,0.737,1.036,1.899, P>0.05). In DF group, there were statistically significant differences in IL-6, CRP, PCT, WBC, and GLU levels among patients in the three infection subgroups ( H=11.174, 15.136, 8.657, 8.348, 3.698, P<0.05).Compared to the mild subgroup, the levels of IL-6, CRP, PCT, WBC and GLU were higher in the severe subgroup were higher( H=111.789,237.066,74.683,83.203,15.328, P<0.05) and the levels of IL-6, CRP, PCT in the moderate subgroup were higher ( H=6.877, 8.846, 5.183, P<0.05). And both of the differences were statistically significant. But there was no statistically significant difference in WBC and GLU level between the mild and the moderate subgroup( H=1.684, 1.039, P>0.05). The severity of infection in diabetic foot patients was positively correlated with the IL-6 level ( OR=1.033, 95% CI: 0.024-0.043, P<0.05). ROC curve showed that AUC of IL-6 for diagnosis in diabetic foots were 0.635. And joint testing showed that the AUC of IL-6+CRP, IL-6+PCT and IL-6+WBC were 0.718, 0.621, and 0.638 respectively. In conclusion,the level of serum IL-6 may be positively correlated with the severity of infection in diabetic foot patients, which may have auxiliary diagnostic value in predicting diabetic foot infection. And it may provide a reference for the grading of infection severity in diabetic foot patients to gauging serum IL-6 level.

Objective:To investigate the characteristics of cardiopulmonary exercise testing and risk factors for decreased aerobic capacity in children with non-acute asthma exacerbations, to assess their cardiopulmonary health and to provide a basis for improvement.Methods:A case-control study.Sixty-one children with non-acute asthma exacerbations treated at the Outpatient Department of Children′s Hospital of Soochow University from October 2022 to December 2023 and 22 control children during the same period were included.Binary Logistic regression was employed to assess risk factors for decreased aerobic capacity in children with asthma.Results:Among the included 61 children with non-acute asthma exacerbations, there were 33 cases in the chronic persistent phase (chronic persistent phase group) and 28 in the clinical remission phase(clinical remission group).There were 22 children in the control group.During the peak exercise phase of the cardiopulmonary exercise testing, the mean kilogram body weight oxygen uptake (VO 2/kg), the percentage of predicted kilogram body weight oxygen uptake, and metabolic equivalents (Met) in the chronic persistent phase group were lower than those in the control and clinical remission phase groups.The mean VO 2/kg recovery from the cardiopulmonary exercise testing in the first minute in the chronic persistent phase group was lower than that in the control and clinical remission phase groups.The median Met and ventilation per minute recovery in the chronic persistent phase group were lower than those in the control group.The median heart rate recovery in asthma children was lower than that in control children.The percentage of cardiopulmonary exercise testing abnormalities was higher in asthma children with symptoms after excise than that in asthma children without symptoms after excise.The percentage of decreased ventilation efficiency in asthma children with symptoms after excise was higher than that in asthma children without symptoms after excise.Multivariate regression analysis showed that a higher body mass index (BMI) ( OR=1.577, 95% CI: 1.113-2.235, P=0.010) and a higher peak respiratory reserve ( OR=1.103, 95% CI: 1.018-1.195, P=0.017) were risk factors of decreased aerobic capacity.The risk of decreased aerobic capacity in the chronic persistent phase was 7.949 times higher than that in the clinical remission phase ( OR=7.949, 95% CI: 1.290-48.996, P=0.025). Conclusions:The aerobic capacity is decreased and ventilatory recovery is slower in children with chronic persistent asthma than those in healthy children.The heart rate recovery in asthma children is slower than that in healthy children.A high BMI, a high peak respiratory reserve, and chronic persistence of asthma are independent risk factors for decreased aerobic capacity in children with non-acute asthma exacerbations.asthma.
