Objective:To understand the current status of self-management positivity of postoperative patients with esophageal cancer and to analyze its influencing factors.Methods:From August 2022 to September 2023, 158 postoperative patients with esophageal cancer at Sun Yat-sen University Cancer Prevention and Control Center were selected by convenience sampling method, and were investigated using a general information questionnaire, Patient Activation Measure (PAM), Fear of Progression Questionnaire Short Form (FOP-Q-SF), and Family APGAR Index (IAPGAR) for a cross-sectional survey, and multiple linear regression was used to analyze the influencing factors of the self-management positivity in patients with postoperative esophageal cancer.Results:Totally 144 questionnaires were effectively collected, of which 106 males and 38 females, with 22 cases aged 18-39 years old, 55 cases aged 40-59 years old, and 67 cases aged ≥ 60 years old. Totally 144 patients scored (59.61 ± 16.07) points on the PAM, (40.45 ± 9.76) on the FOP-Q-SF, and (11.41 ± 2.36) on the IAPGAR, and the results of the multiple linear regression analysis showed that the literacy level, fear of disease progression, and family caring index were the influencing factors of the positivity of the patients′ self-management after the surgery of esophageal cancer ( t=2.54, -13.49, 2.45, all P<0.05). Conclusions:There is always room for improvement in the degree of active self-management of postoperative patients with esophageal cancer. Clinical care workers should pay close attention to the current status of self-management positivity of postoperative patients with esophageal cancer, and formulate a systematic, scientific, and effective intervention strategy for self-management positivity.

Magnetic ferrite nanoparticles (MFNPs) have great application potential in biomedical fields such as magnetic resonance imaging, targeted drugs, magnetothermal therapy and gene delivery. MFNPs can migrate under the action of a magnetic field and target specific cells or tissues. However, to apply MFNPs to organisms, further modifications on the surface of MFNPs are required. In this paper, the common modification methods of MFNPs are reviewed, their applications in medical fields such as bioimaging, medical detection, and biotherapy are summarized, and the future application directions of MFNPs are further prospected.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To investigate the current status of career success of ICU nurses and analyze its influencing factors.Methods:Using the convenient sampling method, a total of 178 ICU nurses from 7 Class Ⅲ Grade A hospitals in Guangzhou, Guangdong Province from April to May 2021 were selected as the research objects. General questionnaire and Chinese version of Career Success Scale were used to conduct the survey through the questionnaire network platform.Results:A total of 178 electronic questionnaires were filled in and 167 valid electronic questionnaires were recovered. The total score of career success of ICU nurses was (35.68±6.07). Multiple linear regression analysis showed that gender of ICU nurses, whether they had regular specialized skills training, and the cooperative relationship of doctors and nurses in departments were the influencing factors of career success scores of nurses ( P<0.05) . Conclusions:The career success level of ICU nurses needs to be improved. It is recommended that nursing managers should clarify the career development path of nurses, broaden the career development space of nurses and enhance their professional autonomy and work enthusiasm.

Objective: To explore the expression of CD45 in newly diagnosed multiple myeloma (MM) and its relationship with clinical efficacy and prognosis. Methods: This study retrospectively analyzed expression and distribution of CD45 in 130 cases of newly diagnosed MM, comparing clinical efficacy and prognosis in CD45⁺/CD45^- groups. Results: ①The CD45⁺ group was 33 cases (25.38%) , and CD45^- group was 97 cases (74.62%) . ②The objective remission rate (ORR) of CD45⁺ and CD45^-group was 33.33% and 64.95%, respectively. The difference was statistically significant (P=0.002) . For patients in Bortezomib regimen, the ORR of CD45⁺ and CD45^- group was 35.71% and 66.25%, respectively. The difference was statistically significant (P=0.005) . ③The median progress free survival (PFS) of CD45⁺ group and CD45^- group was 29.8 (95%CI 10.0-59.0) months vs 34.5 (95%CI 6.0-69.0) months (χ²=14.59, P<0.001) and the median overall survival (OS) was 32.5 (95%CI 10.0-68.0) months vs 37.6 (95%CI 6.0-78.0) months (χ²=11.42, P=0.001) , respectively. Among the patients in bortezomib regimen, The median PFS and median OS of CD45 ⁺ group and CD45^- group were 30.3 (95%CI 10.0-59.0) months vs 36.3 (95%CI 6.0-69.0) months (χ²=14.75, P=0.001) and 34.0 (95%CI 10.0-68.0) months vs 39.5 (95%CI 6.0-78.0) months (χ²=10.62, P=0.001) . ④Cox risk regression model analysis showed that serum creatinine≥176.8 μmol/L (HR=5.078, 95%CI 1.744-14.723, P=0.001) , CD45 positive (HR=14.504, 95%CI 0.168-0.42, P=0.001) , LDH≥220 IU/L (HR=1.308, 95%CI 1.16-2.417, P=0.015) were independent risk prognostic factors. Conclusion CD45 expression is a risk prognostic factor of MM patients. Bortezomib did not improve the poor prognosis of CD45⁺ MM patients.

Objective To describe the adequate feeding of early enteral nutrition in critical patients with cancer, and explore its influencing factors. Methods A retrospective analysis study was performed and 161 patients were involved. Results Nearly 57.14%patients got adequate feeding. The independent risk factors included complications (P < 0.05,OR=2.312,OR 95%CI 1.078-4.958), Acute Physiology and Chronic Health Evaluation Ⅱ (APACHEⅡ) scores (P < 0.05,OR=1.111,OR 95%CI 1.017-1.214) and hypoalbuminemia (P<0.05,OR=2.252,OR 95%CI 1.036-4.892) , and the protective factor was previous enteral nutrition experience (P<0.01,OR=0.123,OR 95%CI 0.021-0.494). Patients who got adequate feeding showed more increase in albumin levels, more decrease in APACHEⅡscores and shorter ICU stays. Conclusions Part of patients got inadequate feeding, due to comprehensive effects of many factors. And adequate feeding may be beneficial to the increase of albumin levels, also helps patients rehabilitate early and shorten the ICU stays.

BACKGROUND:Previous study has observed that the calf acellular dermal membrane exhibits slow repair efficiency, fast degradability speed and other shortcomings in the repair of cartilage defects. OBJECTIVE:To investigate the repair effect of the col agen type Ⅱ-modified acel ular dermal membrane on cartilage defects in rabbits. METHODS:The fetal rabbit chondrocytes were seeded onto the col agen type Ⅱ-modified acel ular dermal membrane, and the composite was then observed under scanning electron microscope at 3, 7 and 14 days. Cartilage defect models were established on the bilateral femoral condyles of 24 New Zealand white rabbits, and these model rabbits were randomly allocated to three groups. The cartilage-acellular dermal membrane and cartilage-collagen type Ⅱ-modified acellular dermal membrane were implanted into the defect regions of control and experimental groups, respectively. Those received no intervention were as blank control group. Collagen type Ⅱ immunohistochemical staining and Wakitani scoring system were performed at 6 and 12 weeks postoperatively. RESULTS AND CONCLUSION:Chondrocytes grew and adhered well in the scaffold. The Wakitani scores in the experimental group were significantly lower than those in the control and blank control groups at postoperative 6 and 12 weeks (P<0.05). At 6 and 12 weeks postoperatively, collagen type Ⅱ immunohistochemical staining was the strongest in the experimental group, with yellow and brown particles in the cytoplasm;the control group was positive for collagen type Ⅱ immunohistochemical staining, while the blank control group was negative for the staining. Our findings suggest that the collagen type Ⅱ-modified acellular dermal membrane is beneficial for the repair of cartilage defects.
