Objective:To investigate the status and the relationship of social support, depression, personality and sleep quality in patients with malignant bone tumors and their relationship, and provide scientific basis for postoperative rehabilitation and nursing.Methods:186 patients with malignant bone tumors undergoing chemotherapy in orthopedics department of the Second Xiangya Hospital of Central South University from January 2017 to December 2019 were selected to complete the Center for Epidemiological Studies Depression Scale (CES-D), the Perceived Social Support Scale (PSSS), the Optimism-Pessimism Scale (OPS), and the Pittsburgh Sleep Quality Index (PSQI). The demographic differences of various variables were compared and the correlation among social support, personality, sleep quality and depression in patients with malignant bone tumors were tested. Then, by structural equation model, the mediating role of personality and sleep quality between social support and depression was analyzed.Results:The incidence of depression in patients with malignant bone tumors was 57.6%(107/186), and the incidence of severe depression was 14.7%(27/186). Depression in patients with malignant bone tumors was negatively correlated with scores of social support and pessimism (all P<0.01), and positively correlated with scores of optimism and sleep quality (all P<0.05); Family support, pessimism, sleep quality and daytime dysfunction can effectively predict depression in patients with malignant bone tumors (all P≤0.05); Structural equation model analysis showed that personality and sleep quality play a chain mediating role between social support and depression. Conclusions:The incidence of depression is higher in patients with malignant bone tumors. Family support, pessimism, sleep quality and daytime dysfunction are predictors of depression in patients with malignant bone tumors. Personality and sleep quality play a chain mediating role in the influence of social support on depression.

Objective:To elucidate the phenomenon that epileptic seizure occurs in patients with epilepsy without definite diagnosis when driving a motor vehicle and its hazards.Methods:From January 2020 to June 2022, 7 epileptic patients who experienced traffic accidents caused by seizures were selected from the First Affiliated Hospital of Soochow University, and their demographic data, traffic accident related data and epilepsy diagnosis and treatment data were summarized and analyzed.Results:A total of 7 adult patients with epilepsy were collected, including 6 males, 4 of whom had been driving for more than 10 years. Among them, 1 patient drove a bus, and the other 6 patients drove private cars. Totally 5/7 of the accidents resulted in personal injury, and 3/7 of the accidents resulted in personal death. In 5 patients, video electroencephalogram showed interictal epileptiform discharges. In 2 patients, the imaging findings suggested the presence of cerebral cortical lesions that may lead to seizures. In terms of the form of seizure, 3 patients′ seizure type was focal to bilateral tonic-clonic, and the other 4 patients were very probable to be focal impaired awareness seizure.Conclusions:Undiagnosed epileptic seizures lead to traffic accidents, endanger patients and public safety, which need to attract attention from both doctors and patients, as well as the whole society.

The mandibular metastatic spread of carcinoma from the thyroid gland is exceedingly rare. Follicular thyroid carcinoma is the second most common type of thyroid carcinoma，accounting for approximately 10% to 15% of all thyroid cancers. The prognosis of FTC is relatively satisfactory. Due to its rich blood transport, it is easy to metastasize hematological, with the main sites of metastasis are bone and lung. However，mandibular metastasis of thyroid follicular carcinoma is rare. We report a case of thyroid follicular carcinoma that metastasized to the ascending ramus of the mandible 21 years after surgery.The operation was successfully completed, and there was no recurrence during postoperative follow-up. Due to the absence of obvious clinical symptoms in the patient, the diagnosis and treatment were challenging. We have provided detailed radiographic and pathological images to facilitate understanding and discussion of the disease.

Objective To propose a quick and low-cost personalized diabetic foot modeling and insole design scheme, so as to reduce the plantar pressure accurately. Methods The foot model of the patient was constructed by scaling the model with foot feature parameters, to make biomechanical analysis on plantar pressure. By means of numerical mapping model of insole elasticity and plantar pressure, the three-dimensional (3D) personalized insole model with gradient modulus was constructed. The insole was then manufactured via 3D printing technology and used for experimental validation. Results The related mechanical parameters from finite element prediction of the foot model constructed by the scaling modeling method were close to those of the CT reconstructed model, and the maximum error was controlled within 15%. Compared with wearing the normal insole, the peak pressure of the personalized insole was effectively reduced by 20%. The time and economic cost of this simplified design was reduced by approximately 90%. Conclusions The design scheme of the diabetes insole shortens the design cycle, and the personalized insole can effectively and accurately reduce the sole pressure, and reduce the risk of foot ulcer, which provides a technical basis for the promotion of the personalized diabetes insole.
