Objective:To investigate the effects of brief mindfulness-based stress reduction(MBSR)on preoperative anxiety in pa-tients undergoing painless gastrointestinal endoscopy.Methods:We enrolled 100 patients scheduled to undergo elective painless gas-trointestinal endoscopy at The First Affiliated Hospital of Zhengzhou University from September 2024 to April 2025.The inclusion cri-teria were:age,18-60 years;body mass index,18.0-28.0 kg/m2;American Society of Anesthesiologists physical status,class Ⅰ orⅡ;and no gender restriction.The patients were assigned to experimental group(n=50)or control group(n=50)using a random num-ber table.A dedicated nursing team implemented the brief MBSR protocol.At 30 minutes before endoscopy,both groups underwent anxiety assessment using the Amsterdam Preoperative Anxiety and Information Scale(APAIS).All the patients received routine preop-erative education.Guided by the nurses,the experimental group received the brief MBSR intervention consisting of mindful body scan-ning,mindful breathing,and mindful music listening,for 12 minutes each at 30 and 15 minutes before the procedure.We recorded the APAIS score,bispectral index(BIS),heart rate(HR),systolic blood pressure(SBP),diastolic blood pressure(DBP),and mean arterial pressure(MAP)at 30 minutes before the procedure(T0),after brief MBSR(T1),and immediately before anesthesia induction(T2);the length of stay in the post-anesthesia care unit(PACU)and postoperative adverse reactions;and the APAIS score and degree of sat-isfaction of patients at discharge from the PACU(T3).Results:Com-(all P<0.05).However,no significant differences were observed be-pared with the control group,the experimental group exhibited sig-nificantly lower APAIS scores,significantly reduced BIS values,and significantly lower HR values at T1 and T2 and a significantly lower APAIS score and a significantly higher degree of satisfaction at T3 tween the groups in SBP,DBP,MAP,postoperative adverse events,or PACU length of stay at any time point(all P>0.05).Conclusion:Brief MBSR is an effective non-pharmacological intervention to cope with perioperative negative emotions in patients undergoing pain-less gastrointestinal endoscopy,which can alleviate preoperative anxiety,reduce electroencephalographic arousal,and improve patient satisfaction.

Objective To compare image quality and clinical usefulness between single breath-hold three-dimensional magnetic resonance cholangiopancreatography with compressed sensing(3D BH-CS-MRCP)and with gradient and spin-echo(3D BH-GRASE-MRCP)and conventional three-dimensional breath-triggered magnetic resonance cholangiopancreatography(3D RT-MRCP).Methods A retrospective analysis was performed in 48 patients(26 males and 22 females,mean age of 53.14±15.19 years),who underwent 3D BH-GRASE-MRCP,3D BH-CS-MRCP and 3D RT-MRCP from September to December 2023.Pancreaticobiliary duct visibility,motion artifacts,background suppression,and overall image quality were scored on a 5-point scale by two radiologists.The relative contrast ratio of three bile duct segmentations(common bile duct,left and right intrahepatic bile ducts)were calculated,and the acquisition time of the three sequences was recorded.Friedman test with a post-hoc test was performed to compare image acquisition time,qualitative and quantitative results.Results The acquisition time was significantly shorter in the two breath-hold groups than for conventional 3D RT-MRCP(P＜0.001).There were no significant differences in overall image quality,motion artifacts,common bile duct and primary branch of intrahepatic bile duct among the three groups.The relative contrast ratio,intrahepatic biliary secondary branch visibility and background suppression score of 3D RT-MRCP and BH-CS-MRCP were significantly higher than those of BH-GRASE-MRCP(P＜0.01).The pancreatic duct(proximal,middle,distal)visibility score of 3D RT-MRCP was significantly better than that of BH-GRASE-MRCP(P=0.002,0.043,0.001),but the gallbladder and gallbladder duct visibility score of BH-GRASE-MRCP was higher than that of 3D RT-MRCP(P=0.036).There was no significant difference between 3D RT-MRCP and BH-CS-MRCP scores except for the middle and distal pancreatic duct visibility.Conclusion Breath-hold 3D MRCP with GRASE and CS can give us feasible options for pancreaticobiliary diagnosis,which significantly shortens the acquisition time without reducing the overall image quality.Compared with BH-GRASE-MRCP,BH-CS-MRCP has better consistency in pancreaticobiliary duct visibility and background suppression.

BACKGROUND: Severe stroke has high rates of mortality and morbidity. This study aimed to investigate the clinical course, causes of worsening, and outcomes of severe ischemic stroke. METHODS: This prospective, multicenter cohort study enrolled adult patients admitted ≤30 days after ischemic stroke from nine hospitals in China between September 2017 and December 2019. Severe stroke was defined as a score of ≥15 on the National Institutes of Health Stroke Scale (NIHSS). Clinical worsening was defined as an increase of 4 in the NIHSS score from baseline. Unfavorable functional outcome was defined as a modified Rankin scale score ≥3 at 3 months and 1 year after stroke onset, respectively. We performed Logistic regression to explore baseline features and reperfusion therapies associated with clinical worsening and functional outcomes. RESULTS: Among 4201 patients enrolled, 854 patients (20.33%) had severe stroke on admission. Of 3347 patients without severe stroke on admission, 142 (4.24%) patients developed severe stroke in hospital. Of 854 patients with severe stroke on admission, 33.95% (290/854) experienced clinical worsening (median time from stroke onset: 43 h, Q1-Q3: 20-88 h), with brain edema (54.83% [159/290]) as the leading cause; 24.59% (210/854) of these patients died by 30 days, and 81.47% (677/831) and 78.44% (633/807) had unfavorable functional outcomes at 3 months and 1 year respectively. Reperfusion reduced the risk of worsening (adjusted odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.12-0.49, P  <0.01), 30-day death (adjusted OR: 0.22, 95% CI: 0.11-0.41, P  <0.01), and unfavorable functional outcomes at 3 months (adjusted OR: 0.24, 95% CI: 0.08-0.68, P <0.01) and 1 year (adjusted OR: 0.17, 95% CI: 0.06-0.50, P  <0.01). CONCLUSIONS: Approximately one-fifth of patients with ischemic stroke had severe neurological deficits on admission. Clinical worsening mainly occurred in the first 3 to 4 days after stroke onset, with brain edema as the leading cause of worsening. Reperfusion reduced the risk of clinical worsening and improved functional outcomes. REGISTRATION ClinicalTrials.gov , NCT03222024.

Objective:To analyze the effect of different gastric mucosa preparation programs on the quality of painless gastroscopy, so as to provide reference for developing mucosal preparation programs.Methods:This was a prospective, randomized controlled study. A total of 150 patients with painless gastroscopy from March 2021 to December 2022 in Shanxi Yuncheng Central Hospital were selected by convenience sampling in this study, they were assigned to control group, water group, and soda water group by random digits table method, each group contained 50 patients. All patients received oral administration of pronase + dimeticone + sodium bicarbonate solution. In addition, control group: prohibited from drinking 4 hours before examination; water group: drinking 200 ml of pure water 2 hours before examination; and soda water group: drinking 200 ml of soda water 2 hours before examination. The clarity score of gastric mucosa and the detection rate of small lesions were compared among the three groups.Results:There were 28 males and 22 females in the control group, aged (47.62 ± 13.83) years old. There were 30 males and 20 females in the water group, aged (44.68 ± 13.61) years old. There were 24 males and 26 females in the soda water group, aged (46.92 ± 12.79) years old. The difference of esophagus, gastric body, gastric antrum and total mucosal clarity scores among the three groups were statistically significant ( F values were 3.68-25.75, all P<0.05). Multiple comparison showed that the esophagus, gastric antrum and total mucosal clarity scores were (1.87 ± 0.58), (1.37 ± 0.34), (6.72 ± 0.92) points in the control group, which were higher than (1.47 ± 0.41), (1.18 ± 0.31), (5.97 ± 0.86) points in the water group, and (1.42 ± 0.41), (1.02 ± 0.22), (5.50 ± 0.79) points in the soda water group, the differences were statistically significant ( t values were 2.67-5.95, all P<0.05). The gastric antrum and total mucosal clarity scores in the water group were higher than in the soda water group, the differences were statistically significant ( t=7.11, 2.71, both P<0.05). The gastric body mucosal clarity score was (1.98 ± 0.74) points in the control group, which was higher than (1.64 ± 0.54) points in the soda water group, the difference was statistically significant ( t=2.66, P<0.05). The gastroscopy examination time and flushin times were (135.20 ± 21.60) s and (1.37 ± 0.43) times in the control group, while (115.52 ± 14.74) s, (0.90 ± 0.29) times and (107.48 ± 13.02) s, (0.62 ± 0.23) times in the water group and soda water group, the control group was higher than the water group and the soda water group, and the water group was also higher than the soda water group, the differences were statistically significant ( t values were 2.38-11.40, all P<0.05). However, there was no statistically significant difference in the detection rate of small lesions among the three groups (all P>0.05). Conclusions:Drinking soda water 2 hours before painless gastroscopy can significantly improve the clarity of patients′gastric mucosa, shorten the examination time and reduce flushing times, but it does not improve the detection rate of small lesions.

Objective:To construct a representative index system for evaluating pediatric orthopedic nursing quality, providing a basis for hospital pediatric orthopedic nursing quality assessment and monitoring.Methods:From April to July 2023, using the "structure-process-outcome" three-dimensional quality structure model as the theoretical framework, a literature review was conducted, and an item pool was formulated. Through two rounds of Delphi method expert consultations, the hierarchical analysis method was finally employed to determine the indicators and their weights at each level.Results:The effective recovery rates of the questionnaire of the two rounds of expert consultations were 100% (20/20), the authority coefficients of experts were 0.87 and 0.88, the coefficients of variation were 0.00 to 0.27 and 0.00 to 0.24. The Kendell harmony coefficients of the second and third indicators in the two rounds of inquiry were 0.140, 0.166 and 0.192, 0.161(all P<0.05). The final pediatric orthopedic nursing quality evaluation index system included 3 primary indicators, 21 secondary indicators and 83 tertiary indicators. Among the primary indicators, the weight of process quality was the highest at 0.493 4, followed by outcome quality at 0.310 8, and the lowest was structural quality at 0.195 8. In the secondary indicators, "assessment criteria of limb blood circulation" had the highest weight at 0.099 8. Conclusions:The constructed pediatric orthopedic nursing quality evaluation index system covers key aspects and is more operationally feasible. It provides better guidance for nursing interventions and quality control.

BACKGROUND:Previous brain studies have mostly focused on adults and fetuses,and the developmental characteristics of young children's brainstems have rarely been studied. OBJECTIVE:To observe the brainstem development characteristics of healthy young children and to explore the age-related differences and their correlation with sex. METHODS:From January 2019 to April 2022,a retrospective study of 3.0T MRI images of 174 children aged 2 to 6 years in the Affiliated Hospital of Inner Mongolia Medical University was conducted,and the median sagittal diameter,area and angle of the brainstem(including midbrain,pons and medulla oblongata)were measured. RESULTS AND CONCLUSION:There is an age-related increase in the anterior and posterior diameters of the midbrain,pons and medulla oblongata in the 2-5 years old group as well as in the longitudinal diameter and area of the midbrain,pons and medulla oblongata in the 2-6 years old group.Except for the longitudinal diameter of the medulla oblongata,all others show a positive correlation with age(r>0,P<0.05).In the 2-3 years old group and 4-5 years old group,the children are in the rapid growth and development stage,and these two age groups can be used as the key observation indicators for the development of young children.The anterior-posterior diameter,longitudinal diameter,area of the pons and total brainstem area are strongly correlated with age,which can be used as the key observation indicators for the brainstem development in young children.

BACKGROUND:The lower cervical vertebral pedicle is the main stress site of the posterior column of the spine,which is of great significance for the maintenance of the stability of the human center of gravity and the reduction of shock.At present,there are few reports on the characteristics of the internal bone trabeculae,and the characteristics of the joint site of the vertebral pedicle with the articular process and the vertebral body.It is urgent to understand the fine anatomical structure of the vertebral pedicle and the relationship and function of each part. OBJECTIVE:To observe the microanatomical morphology of the vertebral pedicle by Micro-CT scanning of cervical vertebra specimens,and to measure and analyze the microstructure and morphometric parameters of the bone trabecula in the cervical pedicle under normal conditions to evaluate the safety performance of the cervical spine. METHODS:Micro-CT scanning was performed on 31 sets of cervical vertebrae C3-C7.By checking and reconstructing the areas of interest in the bone trabecular within the vertebral pedicle,the morphological characteristics and distribution direction of the bone trabecular within the cervical pedicle were observed,and the bone microstructure parameters were detected,and the differences in the bone microstructure of the C3-C7 vertebral pedicle were analyzed and compared. RESULTS AND CONCLUSION:(1)The Micro-CT images showed that the honeycomb bone trabeculae of the pedicle of the lower cervical spine presented a complex network of microstructures.The trabeculae near the cortical bone were lamellar and relatively compact,extending forward toward the vertebral body and backward toward the articular process lamina.Abatoid bone trabeculae extended into the medullary cavity and transformed into a network structure,and then into rod-shaped bone trabeculae.The rod-shaped bone trabeculae were sparsely distributed in the medullary cavity.(2)Statistical results of morphological parameters of bone trabeculae showed that bone volume fraction values in C4 and C5 were higher than that in C7(P＜0.05).The bone surface/bone volume value in C7 was higher than that in C3,C4 and C6(P＜0.05).The bone surface density of bone trabeculae in C7 was higher than that in C3,C4,C5 and C6(P＜0.05).Trabecular thickness in C7 was higher than that in C3,C4 and C5(P＜0.05).Bone surface/bone volume and bone surface density of the left pedicle bone trabecular were greater than those on the right side(P＜0.05).(3)The microstructural changes of C3-C7 were summarized,in which the load capacity and stress of the C7 pedicle were poor,and the risk of injury was high in this area.

BACKGROUND:Nowadays,there are increasing reports on the digitization and visualization system of acupuncture points for adults in traditional Chinese medicine,and the digitization and visualization system of acupuncture points for children in traditional Chinese medicine and the simulation system of acupuncture manipulation for Mongolian medicine training have been reported.However,there are no reports on relevant systems for children in Mongolian medicine. OBJECTIVE:To develop a simulation system of acupuncture points for children in Mongolian medicine,in the hope that it can be used for clinical teaching,manipulation practice and research on acupuncture safety. METHODS:Based on the tomographic anatomical dataset of preschool boys,a three-dimensional(3D)digital virtual anatomical model of children with multiple internal organs and tissues was constructed by using PhotoShop.2021 and Digihuman Reconstruction System software.The relevant annotation information database of 27 acupoints such as Dinghui acupoint of Mongolian medicine was compiled by the Unity database language.The Mongolian gold needle and silver needle were selected to record the acupuncture point teaching video on the 3D printed head and neck resin model of children.In Unity3D software,children's anatomical model,acupoint annotation information database and acupuncture operation video were integrated and coded,and a 3D digital children's Mongolian acupuncture acupoint visualization system integrating simulation acupuncture training,clinical teaching and acupuncture safety research was successfully created. RESULTS AND CONCLUSION:This study was based on real children's specimens.In order to reduce the error of two-dimensional segmentation,the manual layer-by-layer segmentation section image method was used to ensure the accuracy of the 3D model to the greatest extent.The Digihuman Reconstruction System was used to extract and save the individual segmentation data while maximizing the accuracy of the 3D model.PhotoShop.2021 software was used to complete the 3D reconstruction of the outer skin of the head and neck of children and the internal bony structure,cervical spinal cord,blood vessels and nerves,muscles and ligaments.After 3D reconstruction,the basic morphology of each independent structure and the integrity of the overall contour were verified in MeshLab software and the final fine adjustment and anatomical position confirmation were conducted using 3-matic research 13.0 software.The real anatomical morphology of the head and neck of preschool children was successfully simulated and restored.Unity3D software was used to integrate the 3D model of children,acupuncture operation video and acupoint annotation database,and the 3D digital Mongolian acupuncture acupoint visualization system for children was successfully constructed.Based on the real continuous fault ultra-thin dataset of preschool boys in China,China's first 3D digitization and visualization system of acupuncture points in the head and neck of children in Mongolian medicine was developed.Compared with the previous acupuncture soft works,this system is more suitable for the anatomical morphological development characteristics of Asian children,and has a high value of application in the fields of research on the safety of acupuncture in Mongolian medicine,clinical teaching and acupuncture simulation training.
