Objective To investigate the effect of dezocine on emergence agitation (EA) during recovery from sevoflurane-based anesthesia in children.Methods Ninety ASA Ⅰ or Ⅱ children,aged 3-6 yr,weighing 14-31 kg,were randomized into 3 groups (n =30 each):fentanyl group (group F),dezocine group (group D)and control group (group C).Anesthesia was induced with inhalation of 8 ％ sevoflurane and iv injection of atracurium 0.5 mg/kg and remifentanil 1 μg/kg and maintained with inhalation of 2％-3 ％ sevoflurane and infusion of remifentanil at 0.1-1.0 μg· kg-1 · min-1.In groups F,D and C,fentanyl 2 μg/kg,dezocine 0.05 mg/kg and the equal volume of normal saline were injected intravenously 10 min before the end of surgery,respectively,and inhalation of sevoflurane was stopped at the end of operation.The extubation time and length of stay in the postanesthesia care unit (PACU) were recorded.Agitation and the duration were recorded when the children were in PACU.The degree of EA was assessed using the Pediatric Anesthesia Emergence Delirium (PAED) scale.Pain was evaluated using the Children' s Hospital of Eastern Ontario Pain Scale (CHEOPS) and sedation was measured with Ramsay score.The complications such as respiratory depression,postoperative nausea and vomiting were recorded within 24 h after operation.Results Compared with group C,the incidence of EA and PAED scores were significantly decreased and the duration of EA was shortened in groups F and D,CHEOPS scores were decreased at each time point after operation and Ramsay scores were increased at T1 in group F,and CHEOPS scores were decreased and Ramsay scores were increased at each time point after operation in group D (P ＜ 0.05).Compared with group F,the incidence of EA and PAED scores were significantly decreased,CHEOPS scores were decreased at each time point after operation,and Ramsay scores were increased at T2 (P ＜ 0.05),and no significant change was found in the duration of EA in group D (P ＞ 0.05).There was no significant difference in the extubation time and length of stay in the PACU between the three groups (P ＞ 0.05).Conclusion Dezocine 0.05 mg/kg can safely and effectively prevent EA during recovery from sevoflurane-based anesthesia in children and produces better efficacy than fentanyl.

Objective To evaluate the safety and feasibility of totally laparoscopic cholecystolithotomy.Methods Patient baseline characteristics of all 34 totally laparoscopic cholecystolithotomy (TLC) were collected in a database.This group was compared with 34 matched patients who underwent the laparoscopic cholecystectomy (LC) in the same period.Retrospectively,intraoperative and postoperative data were added.Results Operatingtime was significantly longer in the TLC group(124.56 min vs 78.50 min,P ＜0.01).The mean hospitalization expenses of operation was significantly higher in the TLC group(10 970.85 yuan vs 8 666.72 yuan,P ＜0.01).Although not significant less patients have the symptoms of postoperative dyspepsia or diarrhea were seen in the TLC group compared with the LC group (2 vs 6,P =0.26).Intraoperative details and postoperative results such as,blood loss,hospital stay,exhaust time,abdominal bleeding,bile leakage,incision infection have no significant difference.One case of gallstone recurrence was detected in TLC group.No stone recurrence was reported in common bile duct in LC group.Conclusions TLC is effective and feasible for chronic calcular cholecystitis and is particularly favorable for thepatients with medical insurance.However,this approach is technically demanding and should be performed by experienced surgon.

Objective To explore the effect of three surgical positions on needle-assisted thoracoscopic sympathicotomy. Methods Sixty patients undergoing needle-assisted thoracoscopic sympathicotomy were divided into lateral position group，Fowler position group，and modified Fowler position group. The position of the endotracheal tube，noninvasive blood pressure (NIBP) and heart rate were monitored before and after the body position was changed. Moreover，the exposure of surgical field,operation time and comfort degree of patients were recorded. Results The operations were completed successfully under the three positions. Modified Fowler position provided better surgical field and higher comfort degree of patients. Moreover,it was convenient for operative procedure and shortened the operation duration. Conclusion During the operation of needle-assisted thoracoscopic sympathicotomy,modified Fowler position can provide better surgical exposure,enhance comfort of patients,stabilize hemodynamics and shorten operation duration.

Objective To study the expression of transcription factor specificity protein1 and activator protein-2α and the correlation between the two transcription factors in the process of occurrence and development of colorectal cancer. Methods To detect expression of Sp1 and AP-2α mRNA by Real-Time PCR in 60 colon cancer tissues and corresponding normal tissues and the results were compared with the clinical features and pathological characters. The relationship between the expression of Sp1 mRNA and AP-2α mRNA in 60 colon cancer tissues was determined. Results The expression rates of Sp1 mRNA was detectable to highly expressed rates in colon cancer tissues than the matched normal tissues (P ＜0.01),whereas AP-2α mRNA in the colon cancer tissues was significantly lower than that in the matched normal tissues (P ＜0.01). Sp1 mRNA and AP-2α mRNA expression rates had no significant difference between the clinical features (sex, age and tumor areas) respectively. Loss expression or down regulation expression of AP-2α mRNA was detected, whereas Sp1 mRNA was detectable to highly expressed in the different histological grade and Dukes stages. The expression of Spl mRNA and AP-2α mRNA were positively correlated with the histological grade in colon cancer. A significant correlation was found between the expression of Sp1 mRNA and AP-2α mRNA (r =-0.849, P ＜0.001). Conclusion Loss or down regulation expression of AP-2α mRNA,whereas Sp1 was detectable to highly expressed in colon cancer. Negative correlation occurred in Sp1 mRNA and AP-2α mRNA indicated that AP-2α and Sp1 provide the new clues of genetic diagnosis and treatment.

Objective To discuss the correlation between shock index (SI) and severity and the values to forecast the prognosis in patients with septic shock. Methods 127 patients with septic shock admitted to intensive care unit (ICU) of Zhejiang Provincial People's Hospital from January 1st, 2016 to October 31st, 2017 were enrolled, and they were divided into survival group and death group according to the outcomes after 28-day hospitalized. The vital signs, laboratory indexes, acute physiology and chronic health evaluation Ⅱ(APACHEⅡ), sequential organ failure assessment (SOFA), lactate clearance rate (LCR) of 3 hours after fluid resuscitation, and shock index on admission (SI1) and shock index of 3 hours after fluid resuscitation (SI2) were compared between the two groups. The correlation among SI and APACHE Ⅱ, SOFA, LCR was analyzed. The receiver operating characteristic curve (ROC) was drawn to evaluate the prognostic value of SI in patients with septic shock. Results A total of 127 patients were included, 52 in survival group (40.9%) and 75 in death group (59.1%). The SI1, SI2, APACHE Ⅱ and SOFA in the death group were significantly higher than those in the survival group (SI1: 1.62±0.46 vs. 1.35±0.32, SI2: 1.36±0.24 vs. 0.93±0.15, APACHEⅡ:17.5±4.0 vs. 13.6±3.5,SOFA: 9.5±2.3 vs. 6.3±1.5), and LCR was significantly lower than that in the survival group [(14.4±5.2)% vs. (28.6±8.6)%], with statistically significant differences (all P < 0.01). The correlation analysis showed that SI1was significantly positively correlated with APACHEⅡ (r = 0.458, P = 0.000) and SOFA (r = 0.535, P = 0.000), SI2was also significantly positively correlated with APACHEⅡ (r = 0.624, P = 0.000) and SOFA (r = 0.656, P = 0.000), while SI1and SI2were significantly negatively correlated with LCR (r values were -0.348, -0.435, both P = 0.000), and the SI2were more remarkable. ROC curve analysis showed that the area under ROC curve (AUC) of SI1for predicting the prognosis of septic shock was 0.720 [95% confidence interval (95%CI) = 0.620-0.831, P < 0.05]; when SI1= 1.68, the sensitivity, specificity, Yoden index, positive predictive value and negative predictive value were 79.5%, 65.6%, 0.451, 0.759 and 0.636, respectively. The AUC of the SI2to predict prognosis of septic shock was 0.826 (95%CI =0.739-0.826, P < 0.05); when SI2= 1.37, the sensitivity, specificity, Yoden index, positive predictive value and negative predictive value were 85.7%, 87.6%, 0.733, 0.893 and 0.902, respectively. Conclusion Compared with SI1, SI2was more correlated with the severity in patients with septic shock and it had more values to predict prognosis.

Objective: To evaluate the efficacy and safety of nifekalan (NIF) on cardioversion in atrial fibrillation (AF) patients post radiofrequency ablation, and investigate the relevant factors related to the cardioversion efficacy of NIF. Methods: We screened patients with sustained AF rhythm after radiofrequency ablation between November 2016 and July 2018. Participants were treated with intravenous NIF 0.4 mg/kg within 5-10 minutes after ablation. We observed the adverse reaction, and monitored the rhythm, heart rate, QT interval and QTc interval before the medication and at 5, 10, 20, 120 min after the medication. According to the drug outcome of NIF, patients were divided into conversion group and non-conversion group, related factors affecting conversion efficacy were evaluated using logistic regression analysis. Results: (1)A total of 116 patients were enrolled in the study (63 males and 53 females, mean age was (64±18) years). Among them, 72 patients were converted to sinus rhythm, and the overall successful rate was 62.1%. There were 84 patients with persistent AF, of which 50 cases (59.2%) were restored to sinus rhythm. There were 32 patients with paroxysmal AF, 22 cases (68.8%) of them were restored to sinus rhythm. The conversion time was 1.5 to 12 (6.8±3.4)min. (2) In 116 patients, the QT interval and QTc interval were significantly longer after medication than before the drug administration (P<0.01), and peaked at about 10th min, and restored to the level before drug administration at about 120th min. (3) There were 8 cases of bradycardia (6.9%), 3 cases of frequent and short ventricular tachycardia (2.6%). (4) The duration of atrial fibrillation was shorter and left atrial diameter was smaller in the cardioversion group than in the non-cardioversion group (both P<0.05). There were no significant differences in gender, disease history, atrial fibrillation type and structural heart disease between the two groups (P>0.05). (5) Multifactorial logistic regression analysis showed that the duration of atrial fibrillation (OR=0.980, 95%CI 0.966-0.994, P=0.004) and the left atrial diameter (OR=0.888, 95%CI 0.814-0.967, P=0.007) were the factors that influence the cardioversion efficacy of NIF on atrial fibrillation post ablation. Conclusions The total effective rate of NIF was 62.1% in patients witrh sustained AF post radiofrequency ablation, was 68.8% in patients with paroxysmal AF. Besides, NIF has the advantage of short conversion time and few adverse reactions. Left atrium diameter and AF duration were relevant factors that influence the efficacy of NIF of cardioversion in patients with sustained AF after radiofrequency ablation.

Methods A total of 95 patients with epilepsy and 66 control patients who attended our hospital from March 2018 to March 2022 were enrolled,and polysomnography was used to compare sleep structure and respiratory events between the epilepsy group and the control group. Results Compared with the control group,the epilepsy group had significant reductions in REM sleep duration and R%,a significant increase in the longest duration of hypoventilation,and a significant reduction in the lowest oxygen saturation. Conclusion Changes in sleep structure are observed in patients with epilepsy,and patients with epilepsy and obstructive sleep apnea-hypopnea syndrome tend to develop hypoxemia.

Objective:To evaluate partial ventral hepatectomy in the treatment of patients with complicated iatrogenic high bile duct injury.Methods:The clinical data of 8 cases of complicated iatrogenic high bile duct injury treated with the assistance of hepatic ventral segmentectomy from Mar 2013 to May 2020 at Hunan Provincial People's Hospital was retrospectively analyzed.Results:Among the 8 patients, 5 patients underwent partial Ⅳb lobectomy, and 3 patients received partial Ⅳb and Ⅴ segmentectomy of the liver. All the operation was successful without death in hospital. One case developed subphrenic infection and seroperitoneum, which was healed by anti-infection treatment and abdominocentesis. The postoperative follow-up time was 5-90 months, and all of patients are doing well. There was no stenosis in intrahepatic bile duct by postoperative cholangiography or MRI.Conclusions:Quadrate lobe hepatectomy provides a wide view for the treatment of complicated iatrogenic high bile duct injury by fully opening the first porta hepatis and exposing the primary and secondary bile duct branch helping establish a wide patent tension free bile duct-jejunostomy.
