目的:探討雙水平氣道正壓無創通氣（BiPAP）對慢性阻塞性肺疾病（Chronic Obstructive Pulmonary Disease，COPD）合并Ⅱ型呼吸衰竭的治療價值。方法：66例COPD合并Ⅱ型呼衰患者分成通氣組和對照組，對照組給予常規抗感染、祛痰、平喘、腎上腺皮質激素、呼吸興奮劑、低濃度持續吸氧等治療，通氣組除了常規治療外，加無創機械通氣（BiPAP）治療，采用通氣口鼻面罩，設定參數S/T模式，呼吸頻率12~18次/min，氧流量3~5 L/min，吸氣壓（IPAP）10~18 cmH2O，呼氣壓（EPAP）3~6 cm H2O，最初3日持續使用呼吸機，病情好轉后6~20 h/d，通氣天數為5~12天，觀察治療前后動脈血氣分析指標變化。結果：通氣組治療后血氣分析中pH值、SaO2、PaO2、PaCO2較治療前均明顯改善（Plt;0.01），其改善幅度明顯優于對照組，臨床癥狀亦明顯改善。結論：雙水平氣道正壓無創通氣治療COPD合并Ⅱ型呼吸衰竭療效顯著。
Objectives To explore the quality of the reporting of randomized controlled trials (RCTs) of traditional Chinese medicine (TCM) for chronic fatigue syndrome (CFS).Methods We searched the Cochrane Central Register of Controlled Clinical Trials (CENTRAL) (The Cochrane Library, Issue 4, 2006), PubMed, EMbase, the Chinese Biomedical Database (CBMdisc), VIP Information, and China National Knowledge Infrastructure (CNKI) (from establishment to February 2007). We also checked the reference lists of included studies. The quality of the reporting of RCTs was assessed using the 22-item checklist of the CONSORT Statement and other self-established criteria. Results Thirty-eight RCTs were included. The word “randomization” was not present in any of the trials, and only 17 reports used a structured abstract. All trials did not report the scientific background and the rational for the trial, the estimation of the necessary sample size, the methods of allocation concealment and blinding, participant flow chart, ITT analysis, and ancillary analyses. Some authors misunderstood the diagnostic criteria and inclusion criteria, some selected inappropriate control interventions, and some did not clearly describe their statistical methods or used incorrect methods. All 38 trials reported positive outcomes, few reported adverse effects. No report included a general interpretation of the new trial’s results in the context of current evidence in their discussion section, and none mentioned the limitations of the study, the clinical and research implications or the external validity of the trial findings. Conclusion The overall reporting quality of RCTs of TCM for CFS is poor. Defects are found in each section of the reports. Researchers and journal editors should learn and use the principles and methods of evidence-based medicine—especially the use of a transparent prospective clinical trial register and the CONSORT Statement—to improve the design, conduct and report TCM trials.
Objective To investigate clinical features and surgical outcome in children with frontal lobe epilepsy by evaluating the correlation between the predictive factors and seizure freedom. Methods 18 children who underwent frontal lobe epileptogenic resection in the Epilepsy Center of the Children's Hospital of Fudan University between January 2017 and December 2019 with a minimum follow up of 2 year were analyzed retrospectively. Each patient was evaluated with detailed data to predict postsurgical seizure freedom by analysis of variance. Results Of the 18 patients, there were 11 males and 7 females, the age at surgery ranged from 21 months to 11 years old (6.8±2.73) and the duration of seizures was from 1 month to 9 years. 17 patients had focal seizures, while 1 had generalized epileptic spasm. In scalp EEG, interictal and initial ictal discharges were frontal in 11 and 9 cases, respectively. MRI was indicative of FCD in 10 cases, tumor in 2, tuberous sclerosis and gliosis lesion in 1 case each. 4 patients were MRI negative. 11 patients underwent epileptogenic lesion resections directly and 7 cases received depth electrodes implantation and underwent stereo-electroencephalography to localize epileptogenic zone. At follow-up of 2 years, 14 (77.8%) patients remained seizure-free (Engel Ⅰ), 1 (5.6%) had marked seizure reduction (Engel Ⅱ), 2 (11.0%) showed minor improvement (Engel Ⅲ), and only 1 (5.6%) showed no response (Engel Ⅳ). About predictors of seizure recurrence, there were no significant differences in gender, age at surgery, age of seizure onset, duration of epilepsy, lateralization of epileptogenic zone, positive MRI findings, interictal and ictal discharge, etiology, intellectual development and stereo-electroencephalography implantation, while significantly higher rates of seizure freedom correlated with complete the resection of the epileptogenic zone. Conclusions Focal cortical dysplasia is the most common cause in childhood with frontal lobe epilepsy and complete resection of the epileptogenic zone can lead to good seizure control outcome.
