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.

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.

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.

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 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 investigate the influence of different fractions of inspired oxygen used in non-invasive mechanical ventilation on blood gas parameters and serum high mobility group box-1(HMGB1)and interleukin-27(IL-27)levels in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)and type Ⅱ respiratory failure.Methods A total of 152 patients with AECOPD and type Ⅱ respiratory failure were selected as the subjects of the study and divided into group A(n=76)and group B(n=76)using a random number table method.The fraction of in-spired oxygen used in non-invasive mechanical ventilation in the group A was 45％,while was 60％in the group B.The changes in blood gas parameters,serum HMGB1 and IL-27 levels at different time points were compared between the groups;the occurrence of complications during treatment was recor-ded.Results After 7 days of treatment,the arterial oxygen partial pressure[pa(O2)]and pH levels in the group A were significantly higher than those in the group B,while the arterial carbon dioxide partial pressure[pa(CO2)]level was significantly lower than that in the group B(P＜0.05).After 1 day and 7 days of treatment,the serum HMGB1 and IL-27 levels in the group A were significantly lower than those in the group B(P＜0.05).During the treatment period,there was no significant difference in the overall incidence of complications between the two groups(P＞0.05).Conclusion Compared with 60％inhaled oxygen concentration,AECOPD patients with type Ⅱ respiratory failure receiving non-invasive mechanical ventilation with an inhaled oxygen concentration of 45％have better clinical outcomes.The patients'blood gas indicators,serum HMGB1 and IL-27 levels are significantly im-proved,and the treatment is relatively safe.

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.

Objective:To explore and compare the value of radiomic features based on 18F-fluorodeoxyglucose (FDG) PET and CT in distinguishing epidermal growth factor receptor (EGFR) mutation status in patients with lung adenocarcinoma. Methods:Pretreatment 18F-FDG PET/CT images and EGFR gene status of 114 patients (64 males and 50 females, aged range: 35-84 (average age: 61) years) with primary lung adenocarcinoma between January 2017 and December 2017 were retrospectively collected. The volume of interest was drawn manually slice by slice, then the features were extracted by the LIFEx software. The parameters were screened by least absolute shrinkage and selection operator (LASSO) method for 200 times, and ten-fold cross-validation was used to select the best tuning parameter λ. Three models, namely M PET, M CT, M PET+ CT, were constructed by binary logistic stepwise regression. The receiver operating characteristic (ROC) curve was generated and the corresponding area under the curve (AUC), sensitivity, specificity and accuracy were calculated. The AUCs of three models were compared by Delong test. Results:Totally, 53.51%(61/114) patients were with wild type EGFR and 46.49%(53/114) patients had EGFR mutation. There were 3, 3, 7 parameters selected to form M PET, M CT, M PET+ CT, respectively. The AUCs for M PET, M CT, M PET+ CT were 0.730, 0.752 and 0.866 respectively. When the cut-off values were 0.427, 0.522, 0.378 for M PET, M CT and M PET+ CT, the Youden index were up to the maximum as 0.420, 0.405, 0.630, with sensitivities of 83.0%(44/53), 58.5%(31/53), 92.5%(49/53), specificities of 59.0%(36/61), 82.0%(50/61), 70.5%(43/61) and accuracies of 70.2%(80/114), 71.1%(81/114), 80.7%(92/114), respectively. There was no significant difference between AUC of M PET and M CT ( z=-0.320, P>0.05). The differences of AUCs between M PET+ CT and M PET, M PET+ CT and M CT were statistically significant ( z values: 2.963, 2.523, both P<0.05). Conclusions:PET, CT and PET+ CT radiomic features are all associated with EGFR gene expression in lung adenocarcinoma. M PET+ CT has the highest predictive efficiency.
