Objective To observe the relationship between thyroid hormone levels and reduced pulmonary function in elderly male patients with chronic obstructive pulmonary disease(COPD).Methods One hundred and ninety-five cases of elderly male patients with COPD hospitalized from Jan 2006 to Feb 2010 were enrolled.Thyroid function and lung function(FEV1(forced expiratory volume in 1 second),FEV1/FVC(forced vital capacity))were examined routinely.Pulmonary function was compared between normal group(with normal thyroid function)and lower group(with thyroid hypofunction),thyroid function was also compared in patients with different grade levels(mild,moderate,severe,very severe)of pulmonary function.Results FEV1 and FEV1/FVC in thyroid hypofunction group were significantly decreased compared to the normal group(t =3.582,2.981,respectively,P ＜ 0.01).There was significant difference on T3,FT3 in patients with different grade levels of pulmonary function(F =1.959,1.873,respectively,P ＜ 0.05),among them,T3,FT3 were significantly different between mild group and severe group(P ＜ 0.05),but there was no significant difference in other groups(P ＞0.05).T4、FT4 、TSH displayed no significant difference in all groups(P ＞ 0.05).Conclusion Pulmonary function decreased obviously in elderly old male patients with COPD combined with thyroid hypofunction,and the lower level of thyroid hormone,the worse of pulmonary function.

The contents recorded in the rotation registration manual is not only the quantitative indicators for evaluating the quality of residency training, but also the important basis for training assessment and issuance of training certificates. In order to solve the problems of data authenticity, information delay, and repeated entry in the rotation registration manual for residency training, Shanghai East Hospital, Tongji University, launched a project to dock the electronic rotation registration manual with the hospital information system. Through the establishment of the project team, the development of working mechanisms, and the implementation of the project, data analysis was used for process reformation and system optimization, so as to continuously improve management efficiency and medical safety while solving problems and form a set of implementation system with reference significance in practice.

Botulinum toxin(BoNT)is currently the first-line method for treating focal dystonia,which causes muscle paralysis by chemical denervation.Recent neuroimaging studies have found that BoNT treatment could alter neuroplasticity in the brain of patients with focal dystonia.However,the specific central nervous system mechanisms have not been fully elucidated.To this end,here we review the neuroimaging studies on BoNT treatment for dystonia from three aspects:functional magnetic resonance imaging,structural magnetic resonance imaging,and positron emission tomography imaging.It suggests that BoNT may improve the symptoms of dystonia patients by affecting functional connectivity,microstructure,and metabolic levels of the cortex,basal ganglia,thalamus,and cerebellum,etc.Therefore,this review will provide a theoretical reference for further exploring the mechanism and developing potential therapeutic targets of dystonia.

Objective:To evaluate the clinical efficacy and safety of neuro-endoscopic evacuation and microsurgery via keyhole approach in early spontaneous supertentorial intracerebral hemorrhage (ICH). Methods:A prospective multi-center randomized controlled trial was performed; 114 patients with spontaneous supertentorial ICH (time from onset to surgery<6 h) admitted to Departments of Neurosurgery, Shunde Hospital of Southern Medical University, Jiangmen Central Hospital, Affiliated Hospital of School of Medicine of Yanbian University from January 2019 to December 2021 and met the surgical indications were selected. They were divided into endoscopic group (evacuation of intracerebral hematoma under neuroendoscope, n=71) and microscopic group (microsurgery of intracerebral hematoma via keyhole approach, n=43) according to different surgical methods. After 1:1 propensity score matching of the general data, surgical time, hematoma clearance rate, early postoperative re-bleeding rate, Glasgow coma scale (GCS) scores 7 d after surgery, activity of daily living (ADL) scores 6 months after surgery, mortality, and surgery-related complications of 66 patients (33 from each group after matching) were compared. Results:The difference of surgical time between endoscopic group and microscopic group was statistically significant (125[102, 157] mins vs. 175[125, 260] mins, P<0.05). However, hematoma clearance rate (93.00%[80.88%, 96.52%] vs. 93.31%[88.15%, 96.03%]), early postoperative re-bleeding rate (15.2% vs. 9.1%), GCS scores 7 d after surgery (13[10, 15] vs. 12[8, 14]), ADL scores 6 months after surgery (65[45, 85] vs. 55[0, 85]), mortality rate (18.2% vs. 21.2%) and incidences of postoperative intracranial infection and acquired pulmonary infection were not statistically significant between the two groups ( P>0.05). Conclusion:Comparing with microsurgery via keyhole approach, neuro-endoscopy could shorten the surgical time, but not improve the prognosis or safety in early spontaneous supertentorial ICH patients.
