Objective:To evaluate the efficacy of perioperative analgesia with esketamine in the patients undergoing thoracoscopic surgery.Methods:A total of 90 patients of either sex, aged 18-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective thoracoscopic lobectomy under general anesthesia, were divided into 3 groups ( n=30 each) by a random number table method: control group (C group) and different doses of esketamine groups (S 1 group, S 2 group). Before induction of anesthesia, esketamine 0.1 and 0.2 mg/kg were intravenously injected in S 1 group and S 2 group, respectively, while esketamine was not given in group C. Anesthesia was routinely induced in all the three groups. During anesthesia maintenance, esketamine 0.1 and 0.2 mg·kg -1·h -1 were intravenously infused in group S 1 and group S 2, respectively, and the remaining drugs used for anesthesia maintenance were the same in the three groups. Patient-controlled intravenous analgesia (PCIA) was used after operation, and PCIA solution contained sufentanil 2 μg/kg in group C, and esketamine 1 mg/kg was mixed on the basis as previously described in S 1 and S 2 groups. Aminotriol ketorolac was given as rescue analgesia to maintain numeric rating scale score at rest ≤3. The total amount of propofol and remifentanil during operation, effective pressing times of PCIA in postoperative 0-24 h and >24-48 h periods, and requirement for rescue analgesia were recorded. The occurrence of adverse reactions such as respiratory depression, nausea and vomiting, dizziness and salivation, and emergence time were recorded after surgery. The serum interleukin-6 (IL-6) concentration was measured by enzyme-linked immunosorbent assay at 30 min before and after surgery, and the malondialdehyde (MDA) concentration in serum was measured by thiobarbituric acid colorimetric analysis. The postoperative recovery was assessed using the 50-item quality of recovery scale at 1 and 2 days after surgery. The development of chronic pain was followed up by telephone within 1-3 months after surgery. Results:Compared with group C, the intraoperative consumption of remifentanil, effective pressing times of PCIA in postoperative 0-24 h and >24-48 h periods, rate of rescue analgesia, and postoperative serum IL-6 concentration were significantly decreased, and the 50-item quality of recovery scale score was increased in S 1 and S 2 groups, and the postoperative serum MDA concentration was significantly decreased in group S 2 ( P<0.05). Compared with group S 1, the consumption of intraoperative remifentanil was significantly decreased ( P<0.05), and no significant change was found in postoperative serum IL-6 and MDA concentrations in group S 2 ( P>0.05). Compared with group S 2, the postoperative emergence time was significantly shortened in S 1 and C groups ( P<0.05). There was no statistically significant difference in the intraoperative consumption of propofol, incidence of adverse effects and incidence of chronic pain among the three groups ( P>0.05). Conclusions:Esketamine for perioperative analgesia (dose before anesthesia induction 0.1 mg/kg, dose for maintenance of anesthesia 0.1 mg·kg -1·h -1, dose for postoperative PCIA 1 mg/kg) can raise the quality of analgesia and improve the quality of early postoperative recovery in the patients undergoing thoracoscopic lobectomy.

Insomnia disorder is a common clinical mental disorder.Currently, clinical subtyping of insomnia disorder relies primarily on symptomatic descriptions, lacking objective measures and subtyping-based treatment approaches. In recent years, increasing attention has been drawn to sleep electroencephalography (EEG) as a valuable tool for observing abnormal sleep architecture and continuity of insomnia disorder. Sleep EEG analysis holds the potential to elucidate the underlying biological mechanisms of insomnia disorder, facilitating data-driven subtyping and enhancing personalized therapeutic strategies.Five types of sleep EEG subtypes of insomnia disorder were systematically searched and summarized: classifications derived from objective sleep duration, power spectral characteristics, cyclic alternating pattern, spindle and microarousal.EEG characteristics of each subtype and clinical outcomes are discussed.This review aims to provide evidence-based insights for clinical subtyping and personalized treatment of insomnia disorder.

OBJECTIVE To observe the clinical efficacy of endoscopic type Ⅰ tympanoplasty in patients with chronic suppurative otitis media accompanied by fungal otitis media.METHODS Based on the symptom characteristics of the external auditory canal and tympanic mucosa,80 patients were divided into four groups:dry ear without fungi group,dry ear with fungi group,wet ear without fungi group,and wet ear with fungi group.Record its clinical characteristics.Patients with fungal otitis externa should receive medication treatment during the perioperative period.Failure to heal the tympanic membrane repaired 6 months after surgery,recurrent perforation of the graft,and/or persistent inability to dry the ear are considered repair failures.RESULTS A total of 80 patients were included in this study,and the overall healing rate of the tympanic membrane in the four groups of patients was 98.8％.There was no significant difference in the postoperative tympanic membrane healing rate among the four groups of patients.The postoperative air bone conduction difference in all four groups of patients decreased compared to preoperative levels,but the difference was not statistically significant.CONCLUSION Patients with chronic suppurative otitis media accompanied by fungal otitis media undergoing type Ⅰ tympanoplasty showed no decrease in tympanic membrane healing rate and no significant improvement in efficacy.

Japanese encephalitis is an acute central nervous system infectious disease caused by Japanese encephalitis virus (JEV) with brain parenchyma inflammation, characterized by high fever, headache, positive meningeal irritation, impaired consciousness, convulsion, and respiratory failure, with mortality rate as high as 20%-30%, and with neurological sequelae in 30%-50% of survivors. The mechanism of brain damage caused by JEV infection is still unclear, and some studies imply its close relation with immune-inflammatory response. This article reviews the research progress on immune-inflammatory response mechanism of Japanese encephalitis to help to understand its pathogenesis.

Modified electroconvulsive therapy(MECT)has a good therapeutic effect on major depressive disorder(MDD),but its mechanism of action is still unclear.In recent years,accumulated studies have confirmed the effects of MECT on brain structure and function using neuroimaging techniques and large datasets obtained through global collaborations and the conclusions are becoming increasingly consistent.For example,there is an increase in gray matter volume in specific brain regions such as the hippocampus and amygdala,an increase in white matter microstructural integrity and normalization of brain functional connections associated with MDD,such as the hippocampus-amygdala-subgenual anterior cingulate cortex-prefrontal cortex network,hippocampus-thalamus-temporal cortex-parietal cortex network,etc.However,the relationship between these changes and the mechanism of MECT action still needs further investigation.This review provides an overview of the research progress on the structural and functional changes of the brain by MECT to provide methodological support and theoretical basis for its better application in clinical diagnosis and treatment.

Objective·To compare the effects and complications of carbon dioxide laser laryngectomy and open partial laryngectomy in the treatment of laryngeal carcinoma.Methods·Clinical data of 101 patients with stage Ⅰ-Ⅲ laryngeal squamous cell carcinoma admitted to Renji Hospital,Shanghai Jiao Tong University School of Medicine from January 2013 to January 2018 were selected and divided into open surgery group and minimally invasive group according to different surgical methods.The open surgery group received open partial laryngectomy(57 cases),and the minimally invasive group received carbon dioxide laser laryngectomy(44 cases).Follow-up visits were made by telephone and outpatient visits,and the operation time,postoperative laryngeal mucosa edema time,length of stay,5-year survival rate,complication rate and recurrence rate of the two groups were compared in the different clinical stages(stage Ⅰ,stage Ⅱ,and stage Ⅲ)and tumor locations(glottic type and non-glottic type).Results·The operation time,postoperative laryngeal mucosa edema time and length of stay of the minimally invasive group were shorter than those of the open surgery group(P＜0.05).Comparison of the 5-year survival rates of patients with the same clinical stage and glottic type between the two groups showed no statistically significant difference(both P＞0.05);while comparison of the 5-year survival rates of patients with non-glottic type between the two groups(62.5％in the open surgery group vs 0 in the minimally invasive group)showed a statistically significant difference(P＜0.05).In the minimally invasive group,there were 3 cases of complications,including 1 case of fever and 2 cases of lung infection;in the open surgery group,there were 14 cases of complications,including 5 cases of fever,7 cases of lung infection and 2 cases of pharyngeal fistula.The complication rate of patients in the minimally invasive group(6.82％,3/44)was lower than that in the open surgery group(24.60％,14/57),and the difference was statistically significant(P＜0.05);the complication rate of patients with stage Ⅱ and glottic type in the minimally invasive group was significantly lower than that in the open surgery group(P＜0.05).Comparing the recurrence rate of patients in the two groups(10.53％in the open surgery group vs 2.27％in the minimally invasive group),the difference was not statistically significant(P＞0.05).Conclusion·Compared with open partial laryngectomy,carbon dioxide laser laryngectomy has faster postoperative recovery and lower complication rate in the treatment of early and middle laryngeal malignant tumors,so it is worth promoting.

Objective To observe the clinical efficacy of Jiangshabanxia nano-paste on nausea and vomiting in end-stage patients and its effect on the quality-of-life (QOL) in cancer patients. Methods 120 end-stage patients with nausea and vomiting symptoms above grade III were randomly divided into observation group and control group. They were treated with Jiangshabanxia nano-paste and placebo paste respectively. The paste patch was changed every 24 hours and used continuously for 7 days. The nausea and vomiting symptom score, the quality-of-life measurement score and KPS score of cancer patients in the two groups were observed to evaluate the curative effect. Results After 7 days of treatment, the symptom scores of nausea and vomiting in the observation group decreased significantly, the KPS score of the observation group increased, and the effective rate was higher than that in the control group. The score of QOL measurement showed that after treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group decreased, and the score of overall health area increased. After treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group was lower than that in the control group, and the scores of overall health area in the observation group were higher than those in the control group. Conclusion Jiangshabanxia nano-paste has a good clinical efficacy nausea and vomiting in end-stage patients, it also can improve the quality of life end-stage cancer patients.

Objective:To study the effect of eye-open/closed state on 40 Hz auditory steady state response (ASSR) in first-degree relatives of schizophrenia.Methods:Thirty-eight first-degree relatives of schizophrenic patients treated in Shanghai Mental Health Center from March 2010 to October 2011 were selected, and 31 healthy controls were recruited in the same period. All subjects were assessed with schizotypal personality questionnaire (SPQ). The 40 Hz EEG ASSR signals lasting for 3 min under open and closed eyes of all subjects were sequentially collected.Event-related spectrum perturbation (ERSP) and intertribal phase coherence (ITC) were used to evaluate ASSR. SPSS 22.0 software was used for statistical analysis. Two-way analysis of variance was used to compare ITC and ERSP between the two groups under open and closed eyes. Spearman correlation analysis was used to analyze the correlation between each measurement.Results:ITC in group main effect and group×the eye open/closed interaction effect were not significant (both P>0.05), but the main effect of eye-open and eye-closed was significant ( F(1, 67)=10.61, P=0.002). In the healthy control group, the ITC in eye-open state was significantly higher than that in eye-closed state ( P=0.014), and in the first-degree relatives group, the ITC in eye-open state was higher than that in eyes closed state ( P=0.039). ERSP in the main effect of eye-open and eye-closed ( F(1, 67)=0.195, P=0.660), group main effect ( F(1, 67) =0.627, P=0.431), group × the eye-open/closed interaction effect ( F(1, 67)= 1.034, P=0.313) was not significant. Spearman correlation analysis showed that there was no correlation between ERSP (eye open: r=-0.260, P=0.210; eye closed: r=-0.318, P=0.122), ITC (eye open: r=-0.248, P=0.232; eye closed: r=-0.260, P=0.209) and SPQ score in the healthy control group. There was also no correlation between ERSP (eye open: r=-0.387, P=0.226; eye closed: r=-0.363, P=0.238) or ITC (eye open: r=0.126, P=0.485; eye closed: r=0.096, P=0.595) and SPQ score in the first-degree relatives group of schizophrenia. Conclusion:The regulation pattern of 40 Hz ASSR in schizophrenic first-degree relatives is not significantly impaired in the eye-open/closed state, suggesting that the open/closed regulation pattern of 40 Hz ASSR may not be a potential marker for predicting the genetic high-risk prognosis of schizophrenia.

Atrial fibrillation (AF) is a common arrhythmia, which can lead to thrombosis and increase the risk of a stroke or even death. In order to meet the need for a low false-negative rate (FNR) of the screening test in clinical application, a convolutional neural network with a low false-negative rate (LFNR-CNN) was proposed. Regularization coefficients were added to the cross-entropy loss function which could make the cost of positive and negative samples different, and the penalty for false negatives could be increased during network training. The inter-patient clinical database of 21 077 patients (CD-21077) collected from the large general hospital was used to verify the effectiveness of the proposed method. For the convolutional neural network (CNN) with the same structure, the improved loss function could reduce the FNR from 2.22% to 0.97% compared with the traditional cross-entropy loss function. The selected regularization coefficient could increase the sensitivity (SE) from 97.78% to 98.35%, and the accuracy (ACC) was 96.62%, which was an increase from 96.49%. The proposed algorithm can reduce the FNR without losing ACC, and reduce the possibility of missed diagnosis to avoid missing the best treatment period. Meanwhile, it provides a universal loss function for the clinical auxiliary diagnosis of other diseases.
