ABSTRACT
ObjectiveTo study the effect of upper limb robot-assisted therapy on upper limb function and cerebral cortex activation in stroke patients using functional near-infrared spectroscopy (fNIRS). MethodsFrom January, 2022 to January, 2023, 32 stroke patients in Zhejiang Rehabilitation Medical Center were randomly divided into control group (n = 16) and experimental group (n = 16). Both groups received routine neurological medication and routine rehabilitation. The control group received routine upper limb exercises, the experimental group received upper limb robot-assisted therapy. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and fNIRS (oxyhemoglobin, deoxyhemoglobin, and total hemoglobin) before and four weeks after treatment. NIRS_SPM was used for activation analysis, Homer2 was used for blood oxygen concentration analysis. ResultsAfter treatment, the score of FMA-UE increased in both groups (|t| > 5.910, P < 0.001), and was higher in the experimental group than in the control group (t = -2.348, P < 0.05). fNIRS activation results showed that, the activation increased in the experimental group after treatment in channel 17 (F = 9.354, P < 0.01), and it was more than that in the control group (F = 5.217, P < 0.05). fNIRS blood oxygen concentration results showed that, the blood oxygen concentration increased in the experimental group after treatment in channel 17 (F = 12.179, P < 0.01), and it was more than that in the control group (F = 4.883, P < 0.05). ConclusionThe upper limb robot-assisted therapy can improve the upper limb motor function and cerebral cortex activation of stroke patients.
ABSTRACT
Objective To explore the characteristics and biological functions of epigenetic treatment to DNMT1 expression in NSCLC cell lines. Methods Lung cancer cells were divided into 4 groups , and drugs with different concentrations. The effect of epigenetic treatment on NSCLC cell line was detected by CCK-8 and MTT. The effect of epigenetic treatment on the expression of DNMT1 in NSCLC cell line was detected by Western blot. Results CCK-8 and MTT assay showed that treatment with 5-Aza-CdR and MS-275 inhibited the proliferation of NSCLC cells. Western blot showed that treatment with 5-Aza-CdR and MS-275 inhibited the DNMT1 expression in NSCLC cells. Conclusion The expression of DNMT1 gene in the NSCLC cell lines may be suppressed effectively by epigenetic treatment , and the gene may inhibit the proliferation and growth of NSCLC cell lines.
ABSTRACT
@#Contracture and spasticity of ankle joints were major sources of disability in neurological impairment including stroke and cerebral palsy, etc. The manual stretching used in physical therapy might be laborious and time-consuming to the therapists and the outcome was dependent on the experience and the subjectiveend feelingof the therapists. A device was developed that could safely stretch the an-kle joint to its extreme positions with quantitative control of the resistance torque and stretching velocity. Furthermore, it could satisfy a strong need for quantitative and objective measures of the impairment and rehabilitation outcome. This was just the meaning intelligent stretching referred to. This article described the origin of the concept of intelligent stretching and its definition, operational principle, and su-periority and weakness, as well as its application in ankle joint spasticity and contracture in patients with stroke and cerebral palsy.
ABSTRACT
Endobronchial lipomas are rare benign unusual tumors of the respiratory tract. We describe a 65-year-old Chinese man with a history of cough due to an endobronchial tumor. The endobronchial biopsy was not excisional and was unable to evaluate the whole tumor. Then the mass was successfully resected via a right lateral thoracotomy. The histopathological diagnosis confirmed a benign Upoma arising from the membranous trachea. His CT features and fiberoptic bronchoscopic findings are shown along with the pathological results. In describing the management of this case, we stress that the clinical treatment of such tumors should be individualized according to the characteristics of each patient and mass
ABSTRACT
We describe a 22-year-old Chinese woman with a history of cough and hemoptysis due to an unusual giant mediastinal mass with pulmonary involvement. The tumor was successfully resected via a left lateral thoracotomy and a median sternotomy. The histopathological diagnosis was a mature mediastinal teratoma. We describe here the management of this case and wish to emphasise that the surgical resection is feasible in giant mediastinal mature teratoma
ABSTRACT
BACKGROUND: Our former studies have shown that bone marrow mesenchymal stem cells (BMMSCs) can be induced differentiation to vascular smooth muscle-like cells (VSMLCs) and vascular endothelium-like cells (VELCs), which are compatible with collagen-embedded polyglycolic acid scaffolds. OBJECTIVE: To investigate the possibility of constructing small diameter tissue-engineered blood vessels via subcutaneous implantation. METHODS: The cells-scaffold complex was produced by separately seeding VSMLCs and VELCs derived from BMMSCs on polyglycolic acid collagen scaffolds. The two layers were separated by ECMgel. The cells-scaffold complex was subcutaneous implanted into small diameter tissue-engineered blood vessels.RESULTS AND CONCLUSION: Histological analysis of the small diameter tissue-engineered blood vessel walls revealed a typical artery structure, which was similar to natural vessels. The tissue-engineered blood vessels were not broken down under a force of 26.6 kPa. Eight weeks after implantation, the Brdu-labeled seed cells were found in the three layers of the vessel walls. The results revealed that the subcutaneous tissue was a good bioreactor to construct small diameter tissue-engineered blood vessels.
ABSTRACT
We report a 38 year-old Chinese woman with Marfan' syndrome that had an acute type A aortic dissection and severe aortic regurgitation at 21 weeks of gestation. Emergency aortic valve repair and ascending aortic replacement was successfully performed under circulatory arrest with mild hypothermia. The patient underwent a cesarean section and delivered a healthy baby at 38 weeks
