Objective:To evaluate the effect of buccal acupuncture on analgesia after tonsilloadenoidectomy in pediatric patients.Methods:This was a randomized controlled study. One hundred and twenty-six American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ pediatric patients, aged 3-12 yr, weighing 12-34 kg, with body mass index <30 kg/m 2, undergoing elective tonsilloadenoidectomy with general anesthesia, were divided into 2 groups ( n=63 each) by the random number table method: buccal acupuncture group (group B) and control group (group C). All pediatric patients received the same anesthesia induction and intraoperative anesthesia maintenance. The concentration of sevoflurane was adjusted to keep the fluctuation amplitude of vital sign parameters within 20% of the baseline value. After surgery, the drug was immediately stopped and the children were transferred to the postanesthesia care unit for resuscitation under general anesthesia. In group B, the bilateral neck points, upper neck points, hologram points on the head and Zhongjiao points were selected before removal of the tracheal catheter, and disposable acupuncture needles were inserted directly into the acupoints and remained for 20-30 min. Group C received no buccal acupuncture. The pain Assessment Scale (FLACC) was used to assess the severity of postoperative pain. The postoperative agitation score was evaluated by Aono four-point rating method to evaluate the occurrence of agitation. The effective pressing times of patient-controlled analgesia, rescue analgesia and occurrence of nausea and vomiting within 48 h after operation were recorded. The occurrence of bleeding, infection and broken needle at acupuncture sites was recorded. Results:Compared with group C, the effective pressing times of patient-controlled analgesia and incidence of nausea and vomiting were significantly decreased in group B ( P<0.05). There was no significant difference in the rate of rescue analgesia and incidence of postoperative agitation between the two groups ( P>0.05). No infection or broken needle was found at acupuncture sites after buccal acupuncture, only 2 cases had slight bleeding at the puncture site, and there was no abnormality after pressing in group B. Conclusions:Buccal acupuncture can enhance the analgesic effect after tonsilloadenoidectomy in pediatric patients.

Objective This study aims to assess the hazard vulnerability risks in emergency wards to enhance their flexibility and resilience in response to unexpected events.Methods A cross-sectional survey of 73 emergency specialist nurses from 39 hospitals in Zhejiang province was conducted to identify potential threats,assess their probability,and estimate their impact on specific organizations or regions using hazard vulnerability analysis(HVA)based on Kaiser model.The risk values associated with such events were calculated.Results Among the four categories of risk indicators,the highest risk value was attributed to the"system"(37.68％),followed by"staff'(36.53％),"stuff'(29.45％),and"space"(29.25％).The top 10 ranked risk events included exceeding emergency room capacity with patient numbers(52.03％),insufficient staff(47.23％),workplace violence(46.86％),medical litigation(43.64％),accidental removal of high-risk tubes(41.63％),lack of rescue experience or skills(41.51％),specimen errors(40.72％),inadequate experience in observing and handling circulatory support abnormalities(39.22％),information system failures(38.95％),and patient elopement(38.28％).Conclusion Improvements should be made in areas such as leadership planning,system enhancement,communication and collaboration,and adaptability.Emergency ward preparedness and service quality can be further enhanced through measures such as strengthening nurse training and staffing,continuously monitoring item and space-related risks,and implementing bed management and new nurse training programs.

Objective:To investigate the prognosis of patients with initially resectable gastric cancer liver metastasis (GCLM) who were treated by different modalities, and analyze the influencing factors for prognosis of patients.Methods:The retrospective cohort study was conducted. The clinicopathological data of 327 patients with initially resectable GCLM who were included in the database of a nationwide multicenter retrospective cohort study on GCLM based on real-world data from January 2010 to December 2019 were collected. There were 267 males and 60 females, aged 61(54,68)years. According to the specific situations of patients, treatment modalities included radical surgery combined with systemic treatment, palliative surgery combined with systemic treatment, and systemic treatment alone. Observation indicators: (1) clinical characteristics of patients who were treated by different modalities; (2) prognostic outcomes of patients who were treated by different modalities; (3) analysis of influencing factors for prognosis of patients with initially resectable GCLM; (4) screening of potential beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. The propensity score matching was employed by the 1:1 nearest neighbor matching method with a caliper value of 0.1. The forest plots were utilized to evaluate potential benefits of diverse surgical combined with systemic treatments within the population. Results:(1) Clinical characteristics of patients who were treated by different modalities. Of 327 patients, there were 118 cases undergoing radical surgery plus systemic treatment, 164 cases undergoing palliative surgery plus systemic treatment, and 45 cases undergoing systemic treatment alone. There were significant differences in smoking, drinking, site of primary gastric tumor, diameter of primary gastric tumor, site of liver metastasis, and metastatic interval among the three groups of patients ( P<0.05). (2) Prognostic outcomes of patients who were treated by different modalities. The median overall survival time of the 327 pati-ents was 19.9 months (95% confidence interval as 14.9-24.9 months), with 1-, 3-year overall survival rate of 61.3%, 32.7%, respectively. The 1-year overall survival rates of patients undergoing radical surgery plus systemic treatment, palliative surgery plus systemic treatment and systemic treatment alone were 68.3%, 63.1%, 30.6%, and the 3-year overall survival rates were 41.1%, 29.9%, 11.9%, showing a significant difference in overall survival rate among the three groups of patients ( χ2=19.46, P<0.05). Results of further analysis showed that there was a significant difference in overall survival rate between patients undergoing radical surgery plus systemic treatment and patients undergoing systemic treatment alone ( hazard ratio=0.40, 95% confidence interval as 0.26-0.61, P<0.05), between patients undergoing palliative surgery plus systemic treatment and patients under-going systemic treatment alone ( hazard ratio=0.47, 95% confidence interval as 0.32-0.71, P<0.05). (3) Analysis of influencing factors for prognosis of patients with initially resectable GCLM. Results of multivariate analysis showed that the larger primary gastric tumor, poorly differentiated tumor, larger liver metastasis, multiple hepatic metastases were independent risk factors for prognosis of patients with initially resectable GCLM ( hazard ratio=1.20, 1.70, 1.20, 2.06, 95% confidence interval as 1.14-1.27, 1.25-2.31, 1.04-1.42, 1.45-2.92, P<0.05) and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy were independent protective factors for prognosis of patients with initially resectable GCLM ( hazard ratio=0.60, 0.39, 0.46, 95% confidence interval as 0.42-0.87, 0.25-0.60, 0.30-0.70, P<0.05). (4) Screening of potentinal beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Results of forest plots analysis showed that for patients with high-moderate differentiated GCLM and patients with liver metastasis located in the left liver, the overall survival rate of patients undergoing radical surgery plus systemic treatment was better than patients undergoing palliative surgery plus systemic treatment ( hazard ratio=0.21, 0.42, 95% confidence interval as 0.09-0.48, 0.23-0.78, P<0.05). Conclusions:Compared to systemic therapy alone, both radical and palliative surgery plus systemic therapy can improve the pro-gnosis of patients with initially resectable GCLM. The larger primary gastric tumor, poorly differen-tiated tumor, larger liver metastasis, multiple hepatic metastases are independent risk factors for prognosis of patients with initial resectable GCLM and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy are independent protective factors for prognosis of patients with initially resectable GCLM.

Public health and social measures (PHSMs) are one of the most important measures in the prevention and control of COVID-19 and have also been effective in suppressing the spread of influenza viruses, but their effectiveness has not been fully investigated. This study aimed to review the progress of research on the impact of PHSMs on influenza during the COVID-19 pandemic based on the latest evidence of the effectiveness of various PHSMs in controlling transmission of influenza viruses, to provide scientific evidence for optimizing influenza prevention and control strategies.

Objective:To examine the impact of varied surgical treatment strategies on the prognosis of patients with initial resectable gastric cancer liver metastases (IR-GCLM).Methods:This is a retrospective cohort study. Employing a retrospective cohort design, the study selected clinicopathological data from the national multi-center retrospective cohort study database, focusing on 282 patients with IR-GCLM who underwent surgical intervention between January 2010 and December 2019. There were 231 males and 51 males, aging ( M(IQR)) 61 (14) years (range: 27 to 80 years). These patients were stratified into radical and palliative treatment groups based on treatment decisions. Survival curves were generated using the Kaplan-Meier method and distinctions in survival rates were assessed using the Log-rank test. The Cox risk regression model evaluated HR for various factors, controlling for confounders through multivariate analysis to comprehensively evaluate the influence of surgery on the prognosis of IR-GCLM patients. A restricted cubic spline Cox proportional hazard model assessed and delineated intricate associations between measured variables and prognosis. At the same time, the X-tile served as an auxiliary tool to identify critical thresholds in the survival analysis for IR-GCLM patients. Subgroup analysis was then conducted to identify potential beneficiary populations in different surgical treatments. Results:(1) The radical group comprised 118 patients, all undergoing R0 resection or local physical therapy of primary and metastatic lesions. The palliative group comprised 164 patients, with 52 cases undergoing palliative resections for gastric primary tumors and liver metastases, 56 cases undergoing radical resections for gastric primary tumors only, 45 cases undergoing palliative resections for gastric primary tumors, and 11 cases receiving palliative treatments for liver metastases. A statistically significant distinction was observed between the groups regarding the site and the number of liver metastases (both P<0.05). (2) The median overall survival (OS) of the 282 patients was 22.7 months (95% CI: 17.8 to 27.6 months), with 1-year and 3-year OS rates were 65.4% and 35.6%, respectively. The 1-year OS rates for patients in the radical surgical group and palliative surgical group were 68.3% and 63.1%, while the corresponding 3-year OS rates were 42.2% and 29.9%, respectively. A comparison of OS between the two groups showed no statistically significant difference ( P=0.254). Further analysis indicated that patients undergoing palliative gastric cancer resection alone had a significantly worse prognosis compared to other surgical options ( HR=1.98, 95% CI: 1.21 to 3.24, P=0.006). (3) The size of the primary gastric tumor significantly influenced the patients′ prognosis ( HR=2.01, 95% CI: 1.45 to 2.79, P<0.01), with HR showing a progressively increasing trend as tumor size increased. (4) Subgroup analysis indicates that radical treatment may be more effective compared to palliative treatment in the following specific cases: well/moderately differentiated tumors ( HR=2.84, 95% CI 1.49 to 5.41, P=0.001), and patients with liver metastases located in the left lobe of the liver ( HR=2.06, 95% CI 1.19 to 3.57, P=0.010). Conclusions:In patients with IR-GCLM, radical surgery did not produce a significant improvement in the overall prognosis compared to palliative surgery. However, within specific patient subgroups (well/moderately differentiated tumors, and patients with liver metastases located in the left lobe of the liver), radical treatment can significantly improve prognosis compared to palliative approaches.

Objective:To explore the genetic etiology of a pedigree with intellectual disability and explore its pathogenesis.Methods:A Chinese pedigree which had presented at the Henan Provincial People′s Hospital in March 2023 was selected as the study subject. Clinical data of the pedigree were collected, along with peripheral venous blood samples from its members. Whole exome sequencing (WES) was carried out, and candidate variants were verified by Sanger sequencing. Amniotic fluid was collected for prenatal diagnosis. This study was approved by the Medical Ethics Committee of the Henan Provincial People′s Hospital (No. 2019-134).Results:Both the proband (a 6-year-old male) and his mother (30 years old) had various degrees of intellectual and motor impairment. WES revealed that the proband has harbored a de novo heterozygous c. 2563_2567dup (p.Lys856fs) variant of the UBE3A gene, while his mother, maternal grandmother and fetus had all harbored a novel heterozygous c. 409+ 1G>A variant of the RNF13 gene. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be pathogenic (PVS1+ PS1+ PM2_Supporting; PVS1+ PM2_Supporting+ PP3). Conclusion:Based on the clinical manifestations and the result of genetic testing, the heterozygous c.2563_2567dup (p.Lys856fs) variant of the UBE3A gene probably underlay the intellectual disability and developmental delay in the proband, whilst the heterozygous c. 409+ 1G>A variant of the RNF13 gene may underlie the intellectual disability in the proband′s mother and grandmother. Above results have enabled genetic counseling and prenatal diagnosis for this pedigree.

Objective:To explore the status of medical students' sense of school belonging and its relationship with depression and anxiety symptoms in the context of COVID-19 prevention and control.Methods:An online questionnaire survey was conducted among 1 629 full-time students from 8 medical universities. The 18-item psychological sense of school membership scale (PSSM-18), 9-item patient health questionnaire (PHQ-9), and 7-item generalized anxiety disorder scale (GAD-7) were used as measurements. Spearman correlation coefficients were used to analyze the correlations between PSSM-18, PHQ-9, and GAD-7 scores. Logistic regressions were used to analyze the impact of lack of school belonging on depression and anxiety symptoms.Results:The mean score of school belonging was (77.31±14.12), and the detection rates of depression and anxiety symptoms were 25.97% (423/1 629) and 21.92% (357/1 629), respectively. PSSM-18 score was negatively correlated with PHQ-9 scores ( r=-0.52, P<0.001) and GAD-7 scores ( r= -0.49, P < 0.001). After adjusting for covariates, students with low school belongingness had 4.33 times the risk of depression symptoms ( OR=4.33, 95%CI=2.48-7.43) and 5.85 times the risk of anxiety symptoms ( OR= 5.85, 95%CI=3.76-8.15) compared to students with high school belongingness. Conclusion:Lack of school belonging increases the risk of depression and anxiety symptoms. Under the normalization of COVID-19 prevention and control, the school should strengthen health education and support services to improve the students' sense of belonging and alleviate their mental health problems.
