Objective:To investigate the efficacy and treatment adherence of digital cognitive behavioral therapy for insomnia (dCBT-I) in patients with insomnia disorder accompanied by anxiety and depressive symptoms, and to provide empirical evidence for its clinical application.Methods:From December 2023 to December 2024, 102 patients with insomnia disorder accompanied by anxiety and depressive symptoms were recruited from the outpatient department of Inner Mongolia Brain Hospital and randomly assigned to either the dCBT-I group ( n=56) or the digital sleep hygiene education (dSHE) group ( n=46). The dCBT-I group received a 4-week intervention comprising 5 core modules, while the dSHE group received 4 weeks of digital sleep hygiene education. Both groups received weekly guidance from clinical psychologists. Subjective sleep quality (Insomnia Severity Index, ISI), anxiety (Hamilton Anxiety Scale, HAMA), and depressive symptoms (17-item Hamilton Depression Scale, HAMD 17) were assessed at baseline, week 4, week 8, and week 12. Objective sleep parameters (polysomnography, PSG) and cognitive function (Repeatable Battery for the Assessment of Neuropsychological Status, RBANS) were evaluated at baseline and week 4. Linear mixed-effects model was used to analyze the effects of group, timepoint, and their interaction on outcome measures, after controlling medication history, age, sex, education level, ethnicity, and marital status as covariates. Results:A total of 76 patients (dCBT-I: n=42; dSHE: n=34) completed the 4-week intervention, yielding a treatment adherence rate of 74.5%(76/102). At weeks 4, 8, and 12, the dCBT-I group demonstrated significantly lower scores on the ISI, HAMA, and HAMD 17 scales compared to the dSHE group (β=-1.70--0.66, t=-15.38--6.21, all P<0.05), along with higher rates of medication reduction (χ 2=16.40, 9.22, 6.66, all P<0.05). No significant differences were observed in PSG parameters between the two groups. However, the dCBT-I group demonstrated significant improvements in RBANS subdomains, including immediate memory, language function, and delayed memory (β=0.45, 0.86, 1.43, t=3.09, 2.67, 4.36, all P<0.05). Conclusion:dCBT-I is an effective and well-adhered intervention for patients with insomnia disorder accompanied by anxiety and depressive symptoms, warranting broader clinical implementation.

Objective:To summarize and discuss the clinical effect of different forms of anterolateral femoral perforator flap in the repair of acute lower extremity lesions based on the theory of damage control orthopaedics (DCO).Methods:The clinical data of 33 patients with acute destructive wounds in the lower limbs admitted to the First Affiliated Hospital of Wenzhou Medical University from January 2018 to December 2022 were retrospectively analyzed. Under the guidance of the DCO theory, the combined injuries were treated through multidisciplinary consultation, and at the same time, first-stage debridement, bone stent restoration, limb blood transport reconstruction, nerve tendon repair and temporary vacuum sealing drainage (VSD) dressing were applied. After the systemic condition was stabilized, the wound was repaired with anterolateral femoral perforator flaps of different forms. The defect area was 8.0 cm×5.0 cm-35.0 cm×25.0 cm, and the donor flap area was closed in one stage in all cases.Results:30 cases of skin flap survived completely after operation, 2 cases had distal partial necrosis, wound healing after dressing change, 1 case had delayed complete necrosis. The follow-up time was 9-25(14.7±5.3)months. 2 patients were treated with the second stage of repair surgery due to the bloated flap. The rest were satisfied with the shape of the reconstructed flap and the donor flap area, and the ankle joint function score was good.Conclusions:DCO theory combined with anterolateral femoral perforator flap is a safe and effective way to repair the mutilated wounds of lower limbs.

Objective:To understand the needs, problems and challenges of medical personnel in the hospital for scientific research, propose tailored management measurements and suggestions for the hospital.Methods:The questionnaire was prepared by " Questionnaire Star" , the convenience sampling method was used, and information was collected by WeChat online chat group. Factor analysis and multi-dimensional preference analysis were adopted to analyze information collected.Results:Four main factors that affect the scientific research of medical personnel were identified. The most significant impact is the lack of information platform, followed by the lack of environmental atmosphere, lack of personal capacity and lack of personal interest. The research needs of medical personnel are divided into two categories: one is the more basic skill needs, which are mainly targeted at female, nurses, undergraduates, 5~10 years′ working experiences, medium-grade professional title, and people with no knowledge and experience in research. The other one is the needs of skill improvement, which are mainly targeted at younger, physicians, early career, lower professional titles, and had certain research knowledge.Conclusions:So far, there is a lot of space for improvement. It is recommended to promote the capacity building by training, strengthen the research team building and construct of research communication platform, at the same time, update the scientific research management system.

Objective: To investigate the drug resistance of kaempferol reversed adriamycin (ADM)-resistant K562/ADM cells in chronic myelogenous leukemia (CML) and its related mechanism. Methods: Methyl thiazolyl tetrazolium (MTT) method was used to detect the toxicity of ADM on K562 and K562/ADM cells for 24 h. The half inhibitory concentration (IC₅₀) of ADM and the drug resistance multiple for 24 h were calculated. MTT method was used to detect the toxicity of kaempferol on K562/ADM cells for 24 h. The 5% inhibitory concentration (IC₅) and 10% inhibitory concentration (IC₁₀) of kaempferol for 24 h were calculated to determine the concentration of kaempferol in the subsequent experiments. And the cells untreated by the kaempferol were selected as the control group. The cell inhibition after the treatment of ADM for 24 h of the blank control group and kaempferol intervention group was detected by using MTT method. And then the cell inhibition for 24 h and ADM IC₅₀ for 24 h in the above groups were calculated. The ratio of IC₅₀ in the blank control group and kaempferol group was the reversal drug resistance multiple of kaempferol. The fluorescence intensity of ADM in K562/ADM cells treated by kaempferol was detected by using flow cytometry. Western blotting was used to detect the expressions of P-glycoprotein (P-gp), multidrug resistance-associated protein 1 (MRP1), phosphorylated p38 (p-p38), and total p38 (t-p38) protein in K562/ADM cells after the treatment of kaempferol, the specific inhibitor of p38-MAPK signaling pathway SB202190, and the combination of kaempferol and SB202190. Results: After the treatment of ADM for 24 h, the IC₅₀ value of K562 and K562/ADM cells was (0.9±0.6), (28.1 ±3.5) μg/ml, respectively. The drug resistance multiple of K562/ADM cells on the treatment of ADM for 24 h was 31.16 compared with the K562 cells. MTT method showed that kaempferol inhibited the proliferation of K562/ADM cells in a dose-dependent manner. According to the IC₅ and IC₁₀, 0.5 μmol/L and 1.0 μmol/L kaempferol were determined to do the subsequent experiments. After the combined interaction of kaempferol and ADM for 24 h, the ADM IC₅₀ of K562/ADM cells in the blank control group, 0.5 μmol/L kaempferol group and 1.0 μmol/L kaempferol group was (33.7±5.7), (21.4±0.6), (15.9±1.8) μg/ml, respectively (F = 30.85, P < 0.05), and there was a statistical difference of pairwise comparison (both P < 0.05). The reversal drug resistance multiple of K562/ADM cells for 24 h in 0.5 μmol/L kaempferol group and 1.0 μmol/L kaempferol group was 1.58 and 2.12, respectively. Flow cytometry results showed that the mean fluorescence intensity (MFI) of ADM in the blank control group, 0.5 μmol/L kaempferol group and 1.0 μmol/L kaempferol group was 138.4±8.9, 154.3±2.2, 165.7±4.8, respectively, and the difference was statistically significant (F = 161.48, P < 0.05). Compared with the blank control group, after treatment of K562/ADM cells with 0.5 μmol/L and 1.0 μmol/L kaempferol for 24 h, the relative expressions of P-gp, MRP1 and p-p38 protein were decreased in K562/ADM cells (all P < 0.05), but there was no statistical difference in the expression of t-p38 protein (P > 0.05); SB202190 could reduce the relative expressions of P-gp, MRP1 and p-p38 protein (all P < 0.05); after the treatment of SB202190 combined with different concentration of kaempferol, the relative expressions of P-gp, MRP1 and p-p38 protein in K562/ADM cells did not decrease (P > 0.05). Conclusions Kaempferol can decrease the relative expressions of P-gp and MRP1 in K562/ADM cells by inhibiting p38-MAPK pathway, so as to increase the concentrations of ADM and to reverse the drug resistance of K562/ADM cells.
