We actively promote the continuing education, systematize and institutionalize the top-level design, and adopting flexible and diverse training methods. It is of great significance for a staff's entire career to continuously improve professional accomplishment, specialized knowledge and working skills, to adapt to the development of medical science and technology and the reform of health service, and to drive hospital innovation and high-quality development, so as to eventually achieve the goal of "double first-class" construction.
Objective A retrospective summary of the planning, organization, and implementation of the transprovince transfer of patients injured in Wenchuan Earthquake with an emphasis on experiences that may be helpful in future emergency rescue and patient transfer. Methods We collected the daily reports of a patient transfer team attached to the Sichuan Rescue Headquarters from May 12 through May 31, 2008. Results Under the guidance of policy made by the coordinating group of the Ministry of Health, and with the close cooperation of the railway and airline departments the transferring group transferred 10 373 patients in the period studied. The transfers were from 11 disaster areas, including Chengdu, Mianyang, and Deyang, to 20 cities and provinces, including Chongqing, Jiangsu, and Zhejiang. There were no casualties during transfer, and thus the biggest peacetime government-organized trans-province patienttransfer in China’s history achieved success. Conclusion Trans-province patient transfer is an effective measure to compensate for inadequate medical materials, relieve pressure on medical rescue, and guarantee quality of treatment. In the future, emergency plans for different types of disasters will be established, the information platform will be improved, and transfer procedures will be specified.
ObjectiveThe aim was to summarize the seizure and video electroencephalogram (VEEG) characteristics of Dyke-Davidoff-Masson syndrome (DDMS). Methods The case data of four patients with Dyke-Davidoff-Masson syndrome (DDMS) who attended the Epilepsy Center of Hunan Provincial Brain Hospital from March 2022 to March 2023 were retrospectively analyzed to summarize the clinical manifestations of their seizures and the characteristics of their video electroencephalogram (VEEG). Results One case of symptomatic epilepsy with focal seizures; VEEG showed poor background activity alpha rhythmic modulation, amplitude modulation, and increased distribution of slow wave activity in the left frontal and temporal regions; bilateral frontal-central and anterior-temporal regions (more so on the left side), with sharp and slow composite wave issuance.Two cases of symptomatic epilepsy with focal seizures progressing to generalized seizures; in one case, the VEEG showed: background activity α-rhythmic modulation, amplitude modulation is possible, the left frontal, central, anterior temporal region slow wave increase; the left frontal central, parietal anterior temporal region spike-like slow wave activity mixed with spike wave, spike-slow complex wave short-medium-range issuance; the other VEEG showed: background activity α-rhythmic modulation, amplitude modulation is possible, the right frontal central, anterior temporal region slow wave increase; right frontal, central, and anterior temporal region for the famous medium-extremely high-high-amplitude slow wave activity mixed with spike wave, spike-slow complex wave short-medium-range issuance. One case of symptomatic epilepsy with generalized seizures; VEEG showed bilateral occipital alpha rhythm asymmetry, right occipital region <50% of the left side, poor regulation and amplitude modulation; bilateral frontal pole, frontal region, anterior temporal region spike and spiking slow complex wave discharges (right side was prominent), and right pterionic electrodes, anterior temporal and mesial temporal spike and spiking slow wave discharges. Conclusions Epileptic seizures are one of the main clinical manifestations of DDMS and most of them are consulted after a seizure, and their seizure types tend to be focal seizures or progress to generalized seizures, and most of them are drug-refractory epilepsies. The results of VEEG monitoring tend to be characterized by abnormal background activity, increased slow-wave activity, and the site of epileptogenic wave-like discharges tends to be in line with the site of cerebral softening foci or the site of the atrophic side of the brain as shown by cranial MRI.
Objectives About 12.9-50% patients of SARS (Severe Acute Respiratory Syndrome), require brief mechanical ventilation (MV) to save life. All the reported principles and guidelines for therapy SARS were based on experiences from clinical treatments and facts of inadequacy. Neither prospective randomized controlled trials (RCT) nor other high quality evidences were in dealing with SARS. Our objective is to seek safe and rational non-drugs interventions for patients with severe SARS by retrospectively reviewing clinical studies about MV all over the world, which include clinical guidelines, systematic reviews (SR), Meta-analysis, economic researches and adverse events. Methods To search MEDLINE and Cochrane Library with computer. According to the standards of inclucion or exclusion, the quality of the article which as assessed, and relevant data which were extracted double checked. The Meta-analysis was conducted if the studies had no heterogeneity. Results 14 papers were eligible. Due to the significant heterogeneity between these studies, further Meta-analysis could not be conducted, and the authors’ conclusions were described only. Conclusions The outcome of PPV is better than that of VPV. Patients who underwent PPV had a significantly lower mortality than that of VPV. Of course, the volutrauma should be watched. With low tidal volume and proper PEEP, or decreased FiO2, even permissive hypercapnia, the mortality and length of stay were cut down. Non-invasive mechanical ventilation (NIMV) was effective in treating haemodynamical stable patients, minimizing complications and reducing medical staff infection. Patients with serious dyspnea with PaO2/FiO2lt;200, no profit of NIMV, or couldn’t tolerance hypoxaemia were unlikely to benefit from this technique and needed ventilation with endotracheal intubation. Prone position could improve PaO2/FiO2, NO maybe increased pulmonary perfusion, improved V/Q, and raised oxygenation. Furthermore, Inhaled NO sequentially (SQA) was better than Inhaled NO continuouly (CTA). Some studies implied that practice of protocol-directed weaning from mechanical ventilation implemented by nurses excelled that of traditional physician-directed weaning.
ObjectiveTo investigate the clinical effect of Electro-Cortico-Graphy (ECOG) monitoring on refractory epilepsy caused by double pathology. MethodsA retrospective analysis was performed on 10 patients with refractory epilepsy who underwent surgical treatment in Hunan Brain Hospital from January 2020 to December 2021. The diagnosis of postoperative disease was dual pathology of medial temporal lobe sclerosis (MTS) and focal cortical dysplasia (FCD), and the effect of oral drugs was poor. All patients underwent full preoperative evaluation to determine the scope of excision of epileptogenic lesions. Cortical electrodes were used to monitor the location and scope of epileptic discharge during the operation. Epileptogenic lesions were excised, cortical heat cautery was performed, and then cortical EEG monitoring was performed to adjust the excision strategy. The patients were followed up for 24 to 48 months, and the prognosis was assessed according to the Engel scale. ResultsAmong the 10 patients, 1 patient had acute subdural hemorrhage after surgery, 1 patient had speech and naming disorders, but all of them were recovered at discharge. The other patients had no neurological defects such as intracranial infection, hemiplegia, aphasia, etc. Engel grade I was observed in 9 cases (90%) and Engel grade III was observed in 1 case (10%). ConclusionCortical electrode monitoring is safe and effective for refractory epilepsy caused by double pathological signs.
ObjectiveTo investigate the efficacy of vagus nerve stimulation (VNS) in the treatment of refractory epilepsy in children and the key factors affecting its efficacy. MethodsThe clinical data of 22 children with drug-resistant epilepsy who received VNS treatment in the Second People's Hospital of Hunan Province from January 2016 to April 2023 were analyzed. The average seizure reduction rate, effective rate and McHugh grade were used to evaluate the efficacy of VNS after at least 1 year follow-up. Patients with an attack reduction rate of ≥50% were defined as respondents, and Mann-Witney U test and χ2 test were used, respectively, to conduct univariate and multifactor Logistics regression analysis with statistically significant indicators (P<0.05). ResultsAmong the 22 patients, the average attack reduction rate was 12.66% at 1 month, 26.10% at 3 months, 37.47% at 6 months, 48.18% at 9 months and 54.38% at 12 months. The effective rate was 5.00%, 9.00%, 36.00%, 50.00% and 68.00%, respectively. 12 months after operation, there were 3 cases of grade I, 12 cases of grade II, 7 cases of grade III, and 0 cases of grade V. Unifactorial and multivariate Logistic regression analysis showed that the curative effect of epilepsy in children was related to the seizure type, among which the curative effect of general seizure was better than that of focal seizure (OR=0.062, P=0.014), and the curative effect of myoclonic seizure and tonic seizure was better than that of other types in general seizure. ConclusionThe clinical effect of VNS in the treatment of refractory epilepsy in children is time cumulative, and the surgical effect of myoclonic seizures and tonic seizures in general seizures is better.
Objective To investigate the clinical effectiveness and adverse event of preventive medicine for severe acute respiratory syndrome (SARS), and provide clinical data for designing prospective clinical trial. Method Retrospective study on medical staffs, that were exposed to SARS patients, was conducted in two main SARS designated hospitals to obtain information such as SARS exposure risk and preventive measures (medical and others). According to the type of preventive medicine, they were assigned to earthworm’s nucleases and protease (ENP) group, interferon group and blank control group respectively. Exposure risk, suspected sub-clinical infection rate and adverse event rate were compared between the three groups. Results Non-medical preventive measures used in each group were consistent, but the exposure intensity to risk factors between groups was statistically different, which biased the evaluation of clinical effectiveness of preventive medicine. The rate of suspected sub-clinical infection in earthworm’s nucleases and protease (ENP) group, interferon group and control group were 4.5%, 4.5%, and 9.9% (Pgt;0.05), respectively; and adverse event rate were 19.6%, 13.6% (Pgt;0.05), and 0%, respectively. Conclusions Suspected sub2clinical infection rate in ENP group, interferon (INF) group were lower than that in control group, which indicated that these two medicines might be effective in preventing SARS. Adverse event rate in ENP group was similar to that of interferon group, and the symptoms were mild in both groups, which was in accordance with the result of in vitro experiments. ENP spray is a kind of biological preparation; further purification may reduce its adverse event rate. However, because there had excessive confounding factors, especially because of the unequal of exposure risk between three groups, the results of this study can only provide insights to design prospective clinical trial in the future.
