This study aims to explore the potential of polyaspartic acid grafted dopamine copolymer (PAsp- g-DA) chelated Fe ³⁺ for magnetic resonance imaging (MRI) visual photothermal therapy. Polyaspartic acid grafted copolymer of covalently grafted dopamine and polyethylene glycol (PAsp- g-DA/PEG) was obtained by the ammonolysis reaction of poly succinimide (PSI), and then chelated with Fe ³⁺ in aqueous solution. The relaxivity in vitro, magnetic resonance imaging enhancement in vivo and photothermal conversion effect at 808 nm were investigated. The results showed that polymeric iron coordination had good near-infrared absorption and photothermal conversion properties, good magnetic resonance enhancement effect, and good longitudinal relaxation efficiency under different magnetic field intensities. In summary, this study provides a new magnetic resonance visual photothermal therapeutic agent and a new research idea for the research in related fields.

Purpose: The goal of this study was to describe the current status of oncology nurses' behaviors toward end of life (EOL) care in China and to explore the factors associated with oncology nurses’ behaviors toward EOL care. Methods: A cross-sectional design was applied and a convenience sample of 1038 oncology nurses from 22 grade A hospitals were recruited into this study. A general social demographic data questionnaire was administered, and the Chinese version of Nurses’ Behaviors of Caring for Dying Patients Scale was used to assess nurse behavior toward EOL care. The total score ranges from 40 to 200 points. Data were analyzed with SPSS 26.0 software. Results: Chinese oncology nurses' average score of holistic EOL care behaviors was 2.97 ± 0.59. Oncology nurses provide physical care most (3.81 ± 0.76), followed by family care (3.02 ± 0.86), and spiritual care (2.37 ± 0.67). Multiple regression analysis showed that a higher frequency of sharing EOL care experience with colleagues, in-service palliative care education, higher level of head nurse support for EOL patient care, more cases of EOL care, higher working position, and nurse's perceived high level of support were positively associated with behavior toward EOL care. These six factors explained 16.2% of the total variance. Conclusions The results may help provide a basis for converting behavior for EOL care among oncology nurses and design interventions to better improve quality of life for EOL patients with cancer in China.

OBJECTIVETo investigate short term clinical therapeutic effect of fupiyiwei decoction (FPYWD) combined with chemotherapy in treating postoperational large intestine carcinoma and the effect on immune function.

METHODThe 58 cases of postoperational large intestine carcinoma were randomly divided into the traditional Chinese medicine (TCM) group (33 cases) and the control group (25 cases). The toxic and adverse reaction, Karnofsky score and clinical therapeutic effect during chemotherapy were observed, and the level of subgroup of T cells CD3, CD4, CD8 and NK cells were detected. Before and after treatment 28 healthy adult were regarded as normal group.

RESULTThere was no significant difference in clinic therapeutic effect between the TCM group and the control group after 12 chemotherapy treatment courses. But the quality of life the TCM group remarkably better than in the control group (P < 0.05), while the incidence rate of toxic and adverse reaction of chemotherapy in the former group was lower than in the latter (P < 0.05). The level of CD3+, CD4+ T cell and the viability of NK cells in all patients decreased during the chemotherapy treatment course while the level of CD8+ T cell increased, the level of CD3+ T cell and NK cells in peripheral blood in patients increased after treatment, but was lower than in normal group. The level of CD8+ T cell was decreased and was lower than in normal group. There was no significant difference (P < 0.05). The level of CD4 T cell after TCM group, there was significant different in CD4+ T cell between TCM group and control group, normal group (P < 0.05). The viability of NK cell increased but there was no significant difference between the two group.

Objective: To study the role of activating transcription factor 2 (ATF-2) in the growth of mandibular condyle cartilage. Methods: Primary chondrocytes of condyle were cultured. Expression plasmid of ATF-2 and plasmid bcl-2 promoter were transfected into chondrocytes. Luciferase assay and Western blot were used. Results: The absence of ATF-2 in mandibular condyle chondrocytes resulted in a decline in bcl-2 promoter activity, reduction in bcl-2 protein level. Conclusion: The results strongly imply that ATF-2 is required for adequate bcl-2 expression, and play a significant role in controlling growth plate chondrocyte progression.

Objective To study the clinical, laboratory, radiological and pathological findings of patients with hypertrophic cranial pachymeningitis (HCP) in Wegner's granulomatosis (WG) to improve the recognition of the disease, even when it occurs in limited form. Methods Three patients were described and English literatures of biopsy-proven pachymeningitis in WG were reviewed. Results The features of WG-associated pachymeningitis included: ① Frequently occurred early in the course of active limited WG; ② Commonly presented with sever headache and cranial neuropathies in the absence of other meningeal irritative signs; ③ Variable cerebrospinal fluid findings with mild predominantly lymphocytic pleocytosis and elevated protein concentration were major laboratorg findings; ④Elevated ESR and positive serum anti-neutrophilic cytoplasmic antibody (ANCA) could be found in most patients; ⑤ Gadolinium-enhanced brain MRI is very senitive in the detection of pachymeningitis; ⑥A dural biopsy showed granulomatous necrotizing inflammation, giant cell, and evidence of vasculitis;⑦ A favorable response to standard treatment with corticosteroid, cyclophosphamide or other cytotoxic drugs could be observed. Conclusion HCP may be the initial or cardinal manifestation of the limited form of WG. Early diagnosis by ANCA, MRI and dural biopsy may facilitate diagnosis Corticosteroid and immunosupressant are the choices of treatment.
