Objective To construct a telemedicine-based home care system of palliative care for end-of-life cancer patients,and to evaluate its application effect.Methods The construction of the system was based on the literature research,interview results of the patients and their caregivers,and expert group meeting discussions.From May to August 2023,a total of 88 patients,who were about to be discharged from the palliative care ward of a cancer hospital in Hunan Province,were selected as the study subjects using a convenient sampling method,and then they were divided into an experimental group and a control group according to the order of admission.The experimental group was given home care services based on the system,while the control group was given routine discharge guidance and follow-up visits.The duration of the intervention was 8 weeks.The Chinese version of the Edmonton Symptom Assessment Scale and the Chinese version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 palliative were used to evaluate the symptom burden and quality of life between 2 groups before and after intervention;the Telemedicine Satisfaction Questionnaire was used to evaluate the care satisfaction of the experimental group.Results The system of patient side includes 8 main features,namely personal health record establishment,doctor-patient communication,palliative care knowledge library,medication assistance,smart reporting and monitoring,intelligent Q&A,intelligent follow-up,and intelligent forms.The healthcare professional side includes 7 main functions,namely workbench,case management,follow-up management,warning reminder,popularization push,statistical analysis and user management.A total of 67 patients completed the intervention,with 33 in the experimental group and 34 in the control group.The symptom burden of the experimental group was lower than that of the control group(P＜0.05);the quality of life in the experimental group was better than that in the control group(P＜0.05);the score of care satisfaction was(59.00±6.66),which indicated a high level of satisfaction.Conclusion The system can reduce the symptom burden and improve the quality of life of end-of-life cancer patients with good practicality

Objective To evaluate the effect of Internet-based psychosocial intervention for primary caregivers of patients with terminal stage cancer.Methods The relevant randomized controlled trials of Internet-based psychosocial intervention for primary caregivers of patients with terminal stage cancer were systematically searched from 10 databases,such as Chinese Biomedical Literature Database,CNKI,PubMed,Embase and CINAHL and etc.The search period was from the establishment to December 18,2023,and 2 investigators screened the literature according to inclusion and exclusion criteria and extracted data.Cochrane Manual 5.1.0 was used to assess the quality of the literature.Meta-analysis was performed using Revman 5.4 software.Results A total of 9 pieces of the literature including 592 primary caregivers were included.Meta-analysis showed that Internet-based psychosocial intervention reduced the level of anxiety and depression for primary caregivers of patients with terminal stage cancer[MD=-1.64,95％CI(-2.68,-0.59),P=0.002]and the burden of care[SMD=-0.39,95％CI(-0.60,-0.18),P＜0.001],and improved quality of life[SMD=0.25,95％CI(0.01,0.48),P=0.040];further research is needed to explore the effect of reducing the level of distress[MD=-0.88,95％CI(-1.91,0.16),P=0.100].Conclusion The Internet-based psychosocial intervention is effective in improving the anxiety,depression and the burden of care of the primary caregivers of patients with terminal stage cancer,and it can improve the quality of life;further research is needed to explore the level of distress reduction.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective: To compare and correlate the findings of intravoxel incoherent motion (IVIM) magnetic resonance (MR) imaging and arterial spin labeling (ASL) imaging in characterizing parotid gland tumors. Materials and Methods: We retrospectively reviewed 56 patients with parotid gland tumors evaluated by MR imaging. The true diffusion coefficient (D), pseudo-diffusion coefficient (D*), and fraction of perfusion (f) values of IVIM imaging and tumor-to-parotid gland signal intensity ratio (SIR) on ASL imaging were calculated. Spearman rank correlation coefficient, chi-squared, Mann-Whitney U, and Kruskal-Wallis tests with the post-hoc Dunn-Bonferroni method and receiver operating characteristic curve assessments were used for statistical analysis. Results: Malignant parotid gland tumors showed significantly lower D than benign tumors (p = 0.019). Within subgroup analyses, pleomorphic adenomas (PAs) showed significantly higher D than malignant tumors (MTs) and Warthin’s tumors (WTs) (p < 0.001). The D* of WTs was significantly higher than that of PAs (p = 0.031). The f and SIR on ASL imaging of WTs were significantly higher than those of MTs and PAs (p < 0.05). Significantly positive correlation was found between SIR on ASL imaging and f (r = 0.446, p = 0.001). In comparison with f, SIR on ASL imaging showed a higher area under curve (0.853 vs. 0.891) in discriminating MTs from WTs, although the difference was not significant (p = 0.720). Conclusion IVIM and ASL imaging could help differentiate parotid gland tumors. SIR on ASL imaging showed a significantly positive correlation with f. ASL imaging might hold potential to improve the ability to discriminate MTs from WTs.

OBJECTIVE: To evaluate clinical effects of expanded curettage and bone cement filling combined with internal fixation in treating Campanacci III giant cell tumor of knee joint. METHODS: From January 2006 to December 2016, 21 patients with Campanacci III giant cell tumor of knee joint were treated by expanded curettage and bone cement filling combined with internal fixation, including 11 males and 10 females with an average age of(35.24±10.56) years old (ranged from 21 to 61 years old). The courses of disease ranged from 1.5 to 24.0 months with an average of(8.1±4.4) months. Among them, 8 patients were distal femur and 13 patients were proximal tibia. All patients were primary tumors. Musculoskeletal Tumor Society(MSTS) scores were used to evaluate lower limb function before and after operation. X-ray was used to observe healing of lesions and the occurrence of adverse reactions. RESULTS: All incisions were healed at grade A without complications such as infection and internal fixation failure. All patients were followed up from 8 to 56 months with an average of (29.62±9.48) months. MSTS score at the latest follow-up 26.71±2.35 was higher than that of before operation 15.24±1.14, and had statistical significance(=20.160, =0.000). The results of X-ray at final following-up showed internal fixation was well, and no loosening and fracture of subchondral bone. Three patients recurred giant cell tumor and replaced with tumor prosthesis. CONCLUSIONS Expanded curettage and bone cement filling with internal fixation for the treatment of Campanacci III giant cell tumor of knee joint could effectively retain limb function and reduce tumor recurrence rate.

OBJECTIVE: To investigate the correlations of four genetic single nucleotide polymorphisms (SNPs) of brain-derived neurotrophic factor (BDNF) with posttraumatic stress disorder (PTSD). METHODS: A total of 300 patients with sporadic PTSD and 150 healthy subjects (the control group) were selected according to the diagnostic criteria of PTSD (DSM-IV), and the genotypes of the BDNF SNPs G-712A, C270T, rs6265, and rs7103411 were detected by polymerase chain reaction and direct DNA sequencing to determine intergroup differences in the genotypes and allele frequencies; the p values were corrected with the permutation test. RESULTS: The genotypes and allele frequencies of the SNPs G-712A, rs6265, and rs7103411 of BDNF showed no significant intergroup differences (p>0.05). However, the genotype and allele frequencies of C270T showed significant differences between the PTSD group and the control group (p<0.05). CONCLUSION: The SNP C270T of BDNF may be associated with PTSD. Individuals carrying the polymorphic T allele of C270T may be more likely to suffer from PTSD.
