This paper reviews the overview of Death Cafe and its application in palliative care, in order to provide reference for the research and practice of palliative care in China.

Objective:To evaluate the influence of different teaching modes in the creativity of nursing students in China.Methods:A systematic search of PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Literature Database and VIP Database were carried out. Randomized control trials (RCTs) examining the influence of different teaching modes in the creativity of nursing students were included from inception to March 5, 2023. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies according to the Cochrane Handbook for Systematic Reviews of Interventions and combined with the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE), then network Meta-analysis with random effects was performed by using WinBugs 1.4.3 and Stata 17.0 software.Results:A total of 63 studies involving 22 teaching modes were included. The network Meta-analysis showed that Case-based Learning Mode, Evidence-based Nursing Teaching Mode, 3D Printing Model Teaching Mode, Hands-on Inquiry Based Learning, Quality Control Circle Teaching Mode, Six Thinking Hats Teaching Mode, Theory, Drill, Practice, Combine (TDPC, T:theory; D:drill; P:practice; C:combine) Teaching Mode were more effective than Lecture-based Learning Mode ( SMD values were 4.61-22.51, all P<0.05). Sensitivity analysis showed the effectiveness of TDPC Teaching Mode was the greatest in nursing theoretical teaching[surface under the cumulative ranking (SUCRA)=98.08%], the Quality Control Circle Teching Mode was the second most effective (SUCRA=83.13%). The effectiveness of Six Thinking Hats Teaching Mode was the greatest in nursing practical teaching (SUCRA=95.73%), followed by the 3D Printing Model Teching Mode (SUCRA=86.97%). Conclusions:TDPC Teaching Mode, Six Thinking Hats Teaching Mode, 3D Printing Model, Quality Control Circle Teaching Mode were superior to other teaching modes in improving creativity of nursing students.

The global incidence rate of cancer continues to rise,and shows an obvious trend of youth.Implementing digital health interventions can improve the accessibility and quality of palliative care for adolescent cancer patients.At present,there is a gradual increase in related research,but foreign research is the main focus,and domestic research is relatively small,which has not yet attracted the attention of medical staff.Starting from the needs of palliative care for adolescent cancer patients,this article reviews the forms of digital health interventions and their applications in health education,symptom assessment,psychological support and grief counseling,and the development of advance care planning.It analyzes existing problems and proposes nursing strategies,aiming to provide references for clinical nursing practice.

Objective:To investigate the effect of combined treatment of hyperforin(HPF) and amlexanox(AM) on obesity and metabolic disorders.Methods:ob/ob mice were used as an obese mice model and treated with HPF alone(2.5 mg/kg intraperitoneal injection) or combined with AM(50 mg/kg, gavage administration) for 4 weeks. Their body weight and food intake were monitored, glucose tolerance test and insulin tolerance test were performed, serum alanine aminotransferase(ALT) and aspartate aminotransferase(AST) levels were detected. Nuclear magnetic resonance was used to detect the body composition and metabolic cage was used to detect the energy consumption. After sampling, HE staining was used to observed the pathological change of fat and liver tissues, Western blotting and enzyme-linked immunosorbent assay(ELISA) were used to detect the cyclic adenosine monophosphate(cAMP)-protein kinase A(PKA) signaling pathway.Results:Compared to the vehicle-treated mice(54.07 g), HPF-treated mice showed attenuated body weight gain(51.33 g, P=0.042) and reduced total fat mass( P=0.011); while administration of HPF in combination with AM(HPF/AM) further reduced the body weight(47.61 g, P=0.041). HE staining analysis showed that HPF alone or HPF/AM treatment both decreased the diameters of adipocytes and infiltration of white fat( P=0.014, P=0.032) in brown adipose tissues, which resulted in a trend of browning. However, HPF/AM-treatment didn′t further diminish adipocytes or reduce lipid accumulation in brown adipose tissues compared to HPF-treated mice. In addition, the basal oxygen consumption rate(VO 2, P<0.001) and(VCO 2, P=0.002) of HPF-treated mice were mainly elevated in the light phase relative to that of control mice; while HPF/AM-treatment further promote the energy consumption both in the dark phase and light phase. Notably, cAMP-PKA signaling pathway was obviously activated under HPF/AM-treatment in inguinal white adipose tissue. Moreover, HPF/AM-treatment showed beneficial effects on glucose metabolism and fatty liver, as indicated by improved insulin resistance, reduced liver steatosis( P=0.049) and the serum ALT levels( P=0.008). Conclusion:Combined administration of HPF and AM is an effective strategy in the treatment of obesity, improvement of metabolic disorders and alleviation of catecholamine resistance.

Objective:To provide the risk stratification method of hepatoblastoma (HB) suitable for implementation in China and explore the new treatment method for high-risk HB patients.Methods:A total of 100 cases of children and adolescents under 18 years old with newly diagnosed HB in Sun Yat-sen University Cancer Center and Sun Yat-sen University First Affiliated Hospital from September 2014 to September 2018 were included. According to the clinical stage, AFP level, pathological subtype and other factors, patients were stratified into four groups: extremely low-, low-, intermediate- and high-risk. The patients at very low risk were treated with surgery only and followed-up. The patients at very low risk were treated with C5V(Cisplatin+ 5-Fluroracil+ Vincristine) regimen for 4 courses. The patients at intermediate risk were treated with C5VD(Cisplatin+ 5-Fluroracil+ Vincristine+ Doxorubicin)regimen before and after surgery for 6-8 courses. The patients at high risk were treated with C5VD and IIV (ifoshamide+ irinotecan+ vincristine) alternately before and after surgery for 8 courses.Results:One hundred patients were stratified into extremely low-risk, low-risk, medium-risk and high-risk groups for 2, 10, 51 and 37 cases, respectively. Eighty three cases had evaluable lesions before chemotherapy. Among them, 65 patients achieved partial remission, stable disease and progressive disease were observed in 10, and 8 cases, respectively, with a response rate of 78.3%. During a median follow-up of 20 months, 30 patients experienced tumor relapse or progression, and 27 of them died. The 2-years progression-free survival (PFS) and overall survival (OS) rates were 69.2% and 72.0%, respectively. The 2-years PFS rates of patients with extremely low risk, low risk, medium risk and high risk were 100%, 88.9%, 75.3% and 43.2%, respectively. The 2-years OS rates were 100%, 100%, 81.0% and 44.8%, respectively.Conclusions:The novel HB risk classification is simple and feasible. With active comprehensive treatment, patients at extremely low-, low- and medium-risk have excellent outcomes. The survival rate of high-risk HB patients remains to be improved, and new treatment strategies need to be explored.

Objective:To explore the effect of preoperative visit with Child Life mode in the management of preschool children′s anxiety.Methods:A total of 80 cases of children of pre-school age who were operated from September 2018 to February 2019 were selected by cluster sampling method. The children from September to November 2018 who were given the traditional mode of preoperative visit were set as the control group. Children from December 2018 to February 2019 who were given preoperative visit with Child Life mode were set as the experimental group. The Modified Yale Perioperative Anxiety Scale (m-YPAS) scores, Induction Compliance Checklist (ICC) scores and Pediatric Anesthesia Emergence Delirium (PAED) scores were compared between the two groups at 4 different perioperative time points (6 hours after admission, waiting for surgery, induction of anesthesia, and 6 hours after surgery).Results:Totally three patients were suspended from the study due to surgery. A total of 77 children were studied, 38 in the experimental group and 39 in the control group. The score of m-YPAS in the experimental group was significantly lower than that of the control group(17.57±16.64 vs. 42.04±27.46, t value was 3.85, P<0.01) while waiting for surgery. The score of m-YPAS in the experimental group was significantly lower than control group (31.64±27.95 vs. 62.22±25.13, t value was 4.26, P<0.01) at the anesthesia induction. Compare with the control group, the score of m-YPAS in the experimental group showed no significant difference at both time of 6 hours after admission (18.19±17.83 vs.19.85±17.92, t value was 0.87, P>0.05) and 6 hours after surgery(35.61±15.70 vs. 41.81±17.97, t value was 1.37, P>0.05). Compare with the control group the score of ICC in the experimental group was significantly decreased (1.40±1.39 vs. 3.78±2.60, t value was 4.88, P<0.01) at the anesthesia induction. The score of PEAD in the experimental group and control group, there was no significant difference between the two groups (7.18±2.45 vs. 7.85±3.05, t value was 0.91, P>0.05). Conclusions:Compared with the traditional preoperative visit mode, the preoperative visit mode of Child Life can effectively relieve the anxiety of preschool children undergoing general anesthesia surgery while they are waiting for surgery and during anesthesia induction, and can improve the degree of cooperation during anesthesia induction.

Adolescent and young adult (AYA) non-Hodgkin lymphoma (NHL) is different from children and older adults in patients' clinical characteristics, pathological subtypes and genetic characteristics. The standard treatment regimen is still unclear currently. This article briefly describes the epidemiology, molecular biological features and prognostic factors of AYA-NHL, and highlights the curative effects of different treatment options in various subtypes of AYA-NHL, aiming to provide a basis for making clinical standard treatment plans.

Diffuse intrinsic pontine glioma (DIPG) is the main cause of brain tumor-related death among children. Until now, there is still a lack of effective therapy with prolonged overall survival for this disease. A typical strategy for preclinical cancer research is to find out the molecular differences between tumor tissue and para-tumor normal tissue, in order to identify potential therapeutic targets. Unfortunately, it is impossible to obtain normal tissue for DIPG because of the vital functions of the pons. Here we report the human fetal hindbrain-derived neural progenitor cells (pontine progenitor cells, PPCs) as normal control cells for DIPG. The PPCs not only harbored similar cell biological and molecular signatures as DIPG glioma stem cells, but also had the potential to be immortalized by the DIPG-specific mutation H3K27M in vitro. These findings provide researchers with a candidate normal control and a potential medicine carrier for preclinical research on DIPG.

Objective To investigate the effects of 5-hydroxy-1-methylhydantoin (HMH) on kidney injury induced by paraquat (PQ). Methods Fifteen SPF healthy Kunming mice were randomly divided into normal saline (NS) control group, PQ poisoning model group and HMH intervention group, with 5 mice in each group. PQ poisoning model was challenged by one-time gavage of 30 mg/kg PQ solution. The NS group received the same amount of NS by gavage. The HMH group was given 100 mg/kg of HMH immediately after the model was made and continued to be gavaged. Mice in each group were sacrificed 1 day after HMH gavage and heart blood and renal tissue were harvested for examination. The morphological changes of renal tissue were observed under light microscope by hematoxylin-eosin (HE) staining. The content of malondialdehyde (MDA) and the activity of superoxide dismutase (SOD) in renal tissue were detected according to the instructions of the kit. The expression of heme oxygenase-1 (HO-1) and interleukin-1β (IL-1β) in renal tissues were detected by Western Blot. The serum metabolites were detected by gas chromatography time-of-flight mass spectrometry (GC-TOF-MS), the overall distribution of each sample was observed by principal component analysis (PCA), the accuracy of the model was evaluated by multidimensional analysis orthogonal partial least squares-discriminant analysis (OPLS-DA), and the difference metabolites were screened by variable importance in the projection (VIP) value > 1. Results Light microscopic observation showed that: glomerular structure in NS group was clear, there was no hyperemia and inflammatory cell infiltration in renal interstitium and blood vessels. In PQ group, some glomeruli atrophy and necrosis, capillary congestion in glomeruli, infiltration of inflammatory cells around glomeruli, swelling of renal tubular epithelial cells, slight stenosis of lumen, and occasional necrosis and exfoliation of epithelial cells occurred. The degree of kidney injury in HMH group was significantly less than that in PQ group. Compared with the NS group, the content of MDA in the PQ group was significantly increased (nmol/g: 6.70±0.84 vs. 2.70±0.43, P < 0.01) and the activity of SOD was significantly decreased (kU/L: 33.30±4.66 vs. 50.20±3.23, P < 0.05), the protein expression of HO-1 and IL-1β were significantly increased (HO-1/β-actin: 1.11±0.12 vs. 0.61±0.13, IL-1β/β-actin: 0.93±0.13 vs. 0.32±0.06, both P < 0.05). Compared with the PQ group, the content of MDA in the HMH group was significantly decreased (nmol/g: 5.10±0.93 vs. 6.70±0.84, P < 0.05) and the activity of SOD was significantly increased (kU/L:61.00±9.02 vs. 33.30±4.66, P < 0.05), the protein expression of HO-1 was significantly decreased (HO-1/β-actin:0.77±0.07 vs. 1.11±0.12, P < 0.05), however, there was no significant difference in the protein expression of IL-1β (IL-1β/β-actin: 0.87±0.13 vs. 0.93±0.13, P > 0.05). Metabolite detection results showed that: compared with NS group, the levels of creatinine, glycine, succinic acid, fumaric acid and citric acid were significantly increased in the PQ group (VIP value was 1.50, 1.58, 1.64, 1.74 and 1.95 respectively, all P < 0.05), while the levels of palmitic acid, α-tocopherol and 6-phosphogluconic acid were significantly decreased (VIP value was 1.10, 1.55 and 1.56 respectively, all P < 0.05). Compared with the PQ group, the levels of creatinine and citric acid were significantly decreased in the HMH group (VIP value was 1.50 and 1.86, both P < 0.05), while trans-4-hydroxy-proline, D-glyceric acid, 2, 6-fructose phosphate, 6-phosphate gluconic acid and aminomalonic acid were significantly increased (VIP value was 1.36, 1.55, 1.63, 1.68 and 1.76 respectively, all P < 0.05). Conclusions HMH protects kidney injury caused by PQ poisoning by correcting tricarboxylic acids cycle disturbance, lipid peroxidation and energy metabolism disturbance, and its mechanism is related to the regulation of HO-1 protein expression through Nrf2 pathway.
