Objective:To evaluate the effect of an opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine on early postoperative recovery in patients undergoing laparoscopic radical resection of colon cancer.Methods:This study was a randomized controlled trial. From January 2023 to July 2024, 72 patients of either sex, aged 45-65 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective laparoscopic radical resection of colon cancer with general anesthesia at Yichang Central People′s Hospital, were divided into 2 groups ( n=36 each) using a random number table method: control group (group C) and opioid-sparing anesthesia strategy group (group D). Anesthesia was induced with sufentanil and propofol and maintained with propofol and remifentanil in group C. In group D, ultrasound-guided quadratus lumborum block was performed before the start of anesthesia, and anesthesia was induced with esketamine, propofol and lidocaine and maintained with esketamine, propofol, low-dose remifentanil, lidocaine and magnesium sulfate. Patient-controlled intravenous analgesia was carried out at the end of surgery until 48 h postoperatively, using dezocine for rescue analgesia. The Quality of Recovery-15 scores were assessed and recorded at 1 day before operation and 1, 3 and 7 days after operation. Ramsay sedation scores were recorded at 2, 6, 12, 24 and 48 h after surgery. The effective pressing times of patient-controlled analgesia and requirement for rescue analgesia were recorded within 24 h after surgery and during the 24-48 h postoperative period. The intraoperative consumption of opioid, emergence time, duration of postanesthesia care unit stay, time to first flatus, first ambulation time and length of postoperative hospital stay were also recorded. The postoperative complications were recorded during hospital stay and assessed with the Clavien-Dindo classification. Results:Compared with group C, the Quality of Recovery-15 scores were significantly increased at each time point after operation, Ramsay sedation scores were increased at 2, 6 and 12 h after operation, the effective pressing times of patient-controlled analgesia and rate of rescue analgesia were decreased in each postoperative period, the intraoperative consumption of remifentanil was reduced, the time to first flatus, first ambulation time and length of postoperative hospital stay were shortened, the incidence of nausea and vomiting was decreased ( P<0.05), and no significant change was found in the emergence time or duration of postanesthesia care unit stay in group D ( P>0.05). Conclusions:The opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine can raise the quality of early postoperative recovery in the patients undergoing laparoscopic radical resection of colon cancer.

In recent years, the relationship between children′s chronic diseases and neuropsychiatric diseases and their pathogenesis have become a hot and difficult issue in pediatric research.Bronchial asthma (asthma) is a co-mmon chronic airway inflammatory disease in children.The latest large-scale population-based reports confirmed the close relationship between asthma and attention deficit hyperactivity disorder (ADHD), the most common neurodevelopmental disorder in children.Therefore, the specific relationship between asthma and ADHD, and the latest research progress of their risk factors were reviewed in this article in order to understand the specific relationship between them and its risk factors, so as to facilitate the long-term clinical management of asthmatic children.

Objective: To explore the prenatal dietary and environmental risk factors in children aged 6-16 years with asthma (CWA) comorbid neuropsychiatric disorders. Methods: This cross-sectional study was conducted from March 2016 to March 2017.CWA aged 6 to 16 years were recruited as the study participants at the Outpatient Asthma Unit of Guizhou Provincial People′s Hospital, China.Informed consent was obtained from their parents, and their parents were invited to participate in the Mini International Neuropsychiatric Interview of children and adolescents (MINI Kid) to assess the current neuropsychiatric disorders.Meanwhile, the questionnaires information about prenatal diet and environment were collected from their mothers as well.Patients were divided into 2 groups, one group with asthma comorbid neuropsychiatric disorders and the other with asthma only.Single factor analysis and multivariate non-conditional Logistic regression analysis were used to determine the risk factors associated with neuropsychiatric comorbidity. Results: The study consisted of 261 patients (male: 163 cases, female: 98 cases) with asthma, with the age of (11.25±3.12) years, the rate of asthma comorbid neuropsychiatric disorders was 26.4% (69/261 cases). Single factor analysis showed that prenatal tobacco smoke exposure, winter coal combustion, food additives had statistically significant differences between the 2 group (χ²=7.385, 3.993, 4.529, all P<0.05), the other factors were not significantly different between two groups (all P>0.05); multivariate analysis indicated that prenatal tobacco smoke exposure was the independent risk factor for neuropsychiatric comorbidity in CWA (OR=5.098, 95%CI: 1.089-23.871, P=0.039). Conclusions The result revealed that the prenatal tobacco smoke exposure is the independent risk factor for neuropsychiatric comorbidity in CWA, need to enhance the propaganda and education of negative effects for parents should be enhanced during pregnancy to diminish the prevalence.

Objective To observe long-term follow-up results of in-stent restenosis by digital subtraction angiography(DSA) method after angioplasty and stenting with the Gateway-Wingspan stenting system in middle cerebral artery(MCA).Methods Consecutive patients with ischemic stroke and Wingspan stent placement were enrolled into our study.The proportion of in-stent restenosis and ischemic stroke associated with restenosis were evaluated by DSA after 6 and 12 months of stent placement.Results 30 patients with stenosis/occlusion of MCA underwent Wingspan Stent successfully.All of the patients finished follow-up except two patients(6.7％ ) who died in the first three months after stenting.At the sixth months follow-up,in-stent restenosis was observed in 7 patients( 23.3％ ) with average (69.0 ± 9.8 )％ in-stent restenosis degree.However,no additional in-stent restenosis was found at the twelfth month,two patients among the 7 with in-tent restenosis were suffered with artery occlusion in stent.Conclusion In-stent restenosis after Wingspan stenting in middle cerebral artery was more common during the first six months,and 85.7％ with ischemic stroke.It was worthy of paying attention to prevent in-stent restenosis at the first six months after stenting.
