Objective: To investigate the potential of conventional cranial computed tomography (CT) in assessing the early neurological deterioration(END), long-term prognosis, and traditional Chinese medicine (TCM) syndrome elements during the acute phase in patients with acute ischemic stroke (AIS). Methods: This study included 101 patients with AIS onset within 24 h in the Emergency Department of Fangshan Hospital, Beijing University of Chinese Medicine, from November 2019 to May 2021. To investigate the correlation between the relevant characteristics of the first conventional cranial CT in patients with AIS onset within 24 h and END, 90 d prognosis, and initial syndrome elements, the presence or absence of END, the 90 d prognosis (non-disabling outcome or functionally independent outcome), and the establishment of syndrome elements (internal fire, phlegm-dampness, blood stasis, qi deficiency, yin deficiency) were used as dependent variables and grouping criteria. Results: This study included 61 males and 40 females, with an age of (64.43±10.56) years. The time from onset to conventional cranial CT examination was 3.50 (1.50, 9.75) h. Among the patients, there were 70 cases (69.3%) of mild AIS, 30 cases (29.7%) of moderate AIS, and one case (1.0%) of severe AIS. Fifteen patients (14.9%) received intravenous thrombolysis. Among the 101 patients, six syndrome elements were observed within 24 h of onset: internal wind in 101 cases (100.0%), internal fire in 58 cases (57.4%), phlegm-dampness in 60 cases (59.4%), blood stasis in 67 cases (66.3%), qi deficiency in 39 cases (38.6%), and yin deficiency in 23 cases (22.8%). The incidence of END was higher in patients with lesions in the contralateral cerebral hemisphere to the affected limb (32.9%) than in those without such lesions (10.7%), showing a strong positive correlation with END occurrence (OR=4.082, P = 0.026). The incidence of END was higher in patients with lesions in the basal ganglia region (33.3%) and the carotid system blood supply area (32.8%) than in those without lesions in the basal ganglia region (15.8%) and the carotid system territory (14.7%), showing moderate positive correlations with END occurrence (OR=2.667, P =0.047; OR=2.836, P=0.044). The proportion of non-disabling outcomes was lower among patients with white matter degeneration (30.8%) and lesions in the contralateral cerebral hemisphere to the affected limb (52.1%) than in those without white matter degeneration (63.6%) and without such lesions in the contralateral cerebral hemisphere to the affected limb (78.6%), both showing strong negative correlations with the occurrence of non-disabling outcomes (OR=0.254, P=0.034; OR=0.296, P=0.015). Similarly, the proportion of functionally independent outcomes was lower among individuals with white matter degeneration (30.8%) and lesions in the contralateral cerebral hemisphere to the affected limb (64.4%) than in those without white matter degeneration (77.3%) and without such lesions in the contralateral cerebral hemisphere to the affected limb (89.3%), both also showing strong negative correlations with the occurrence of functionally independent outcomes (OR=0.131, P=0.001; OR=0.217, P=0.014). The incidence rates of internal fire, blood stasis, and yin deficiency syndrome elements were 66.7%, 73.0%, and 30.2%, respectively, among patients with lesions in the basal ganglia region, compared to 42.1%, 55.3%, and 10.5% among those without lesions in this region. The presence of lesions in the basal ganglia region showed moderate to strong positive correlations with internal fire and yin deficiency syndrome elements (OR=2.750, P=0.016; OR=3.670, P=0.028). Patients with lesions in the centrum semiovale and corona radiata regions (66.7%) had a higher incidence of qi deficiency than those without lesions in this region (33.7%), showing a strong positive correlation with the occurrence of qi deficiency (OR=3.931, P=0.022). No CT characteristics were found to be correlated with phlegm-dampness syndrome elements. Conclusion The first cranial CT in patients with AIS has potential application value in predicting disease progression, assessing prognosis, and diagnosing syndromes, which can provide physicians with diagnostic and treatment decisions to improve the long-term prognosis of patients with AIS.

Objective:To analyze the evaluation of the application effect and deficiency of nurses acting as standardized parents in the graduation examination of standardized residency training of pediatrics and further improve and promote the level of standardized parents.Methods:A questionnaire survey was used to collect the scores of nurse standardized parents by students and examiners who took part in the graduation examination of standardized residency training of pediatrics in 2021. And the self-evaluation scores of standardized parents were collected. Counting data were represented by the number of cases and composition ratio. A Chi-square test was used to compare the rates.Results:A total of 125 questionnaires from students and 37 questionnaires from nurse standardized parents were collected, and the overall satisfaction (very satisfied + satisfied) of standardized parents reached 121 (96.80%). In the three dimensions of simulation ability, compliance with question-and-answer rules, and simulated attitude, students believed that the consistency between standardized parents and actual parents in simulated altitude was lower than that in the simulation ability and compliance with question-and-answer rules ( P=0.007, P=0.001). The overall satisfaction of standardized parents (very satisfied + satisfied) reached 87.38% (388/444). There were 26 (70.27%) nurse standardized parents who had the lowest satisfaction with their own performance ability, followed by 28 (75.68%) cases of imitation ability and 30 (81.08%) cases of adaptability. Conclusions:It is feasible to adopt nurse standardized parents in the assessment of standardized residency training of pediatrics, and both students and examiners have higher satisfaction. The next step is to improve the training of nurses standardized parents in the attitude of simulation and, at the same time, enhance the training of imitation ability and adaptability, so as to further expand the construction of standardized parents.

Objective:To evaluate the safety and effectiveness of dual-plane breast augmentation via endoscopic assisted axillary approach.Methods:A retrospective analysis was conducted on 215 female patients who underwent dual-plane breast augmentation via endoscopic assisted axillary approach from March 2019 to March 2021 (15 cases at Longhua Maternal and Child Health Hospital and 200 cases at Chongqing Huamei Hospital). The patient′s age was 22-45 (32.32±5.67) years. 42 cases underwent dual-plane breast augmentation via endoscopic assisted axillary approach, by using a combination of blunt and sharp methods to separate the cavity; while 173 cases used sharp methods to separate cavities. The complications related to breast augmentation were evaluated during a follow-up period of 6 to 18 months.Results:None of the 215 patients experienced wound infection, postoperative hematoma formation, or skin burns. The long-term complications included 1 case (0.46%) of grade Ⅰ capsule contracture, 1 case (0.46%) of grade Ⅲ capsule contracture, and 12 cases (5.58%) of nipple areola sensory impairment or reduction. A patient with grade Ⅲ capsule contracture underwent right capsulotomy and replacement of the prosthesis.Conclusions:The endoscope-assisted transaxillary dual-plane breast augmentation surgery has higher safety and satisfactory, worthy of clinical promotion and application.

Objective To examine the cognitive status and influencing factors of spiritual care among neurosurgery nur-ses,providing a basis for developing a spiritual care management plan for neurosurgery nurses.Methods A convenience sam-pling method was used to select 741 neurosurgical nurses from 35 tertiary hospitals across 14 prefecture-level cities in Guangdong Province from October 2022 to March 2023.A self-developed general information questionnaire and the Chinese version of the Spiritual Care-Giving Scale(C-SCGS)were utilized for the questionnaire survey.Results The average cognitive score for spirit-ual care among neurosurgery nurses was 169.07±27.66.Factors influencing the total score and various dimensions of spiritual care cognition included educational background,receipt of spiritual care education,position,number of night shifts,marital sta-tus,and employment type(P＜0.05).Conclusion Neurosurgical nurses'spiritual care cognition is at a moderate level,indi-cating a need for targeted training programs to enhance their understanding and practice of spiritual care based on their status and characteristics.

Objective To investigate the clinical significance and serum changes of asprosin(ASP)levels in patients with essential hypertension and early renal damage.Methods According to urinary albumin/creatinine ratio(UACR),160 patients with essential hypertension were divided into the simple hypertension group(78 cases)and the early renal damage group(82 cases).Another 60 healthy subjects were selected as the control group.The differences of serum ASP,interleukin-6(IL-6)and UACR levels were compared between groups.The correlation between ASP and blood pressure,IL-6 and UACR was analyzed.Logistic regression analysis was used to analyze the factors influencing early renal damage in essential hypertension.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of each index for early renal injury.Results The serum levels of ASP,IL-6 and UACR were higher in the early renal damage group than those in the control group and the simple hypertension group(all P＜0.05).The serum levels of ASP and IL-6 showed an increasing trend with the increase of blood pressure.ASP was positively correlated with systolic blood pressure(SBP),diastolic blood pressure(DBP)and IL-6 levels in patients with essential hypertension(all P＜0.05).Serum ASP was positively correlated with SBP,UACR and IL-6 levels in essential hypertension patients(P＜0.05),and serum ASP was positively correlated with UACR and IL-6 levels in the early renal damage group(P＜0.05).Logistic regression analysis showed that higher levels of SBP,ASP and IL-6 were independent risk factors for early renal damage.ROC curve showed that ASP had the largest area under the curve(AUC)of 0.972(95%CI:0.950-0.993).The AUC of combined detection of ASP+IL-6+SBP was 0.986(95%CI:0.972-0.999).Conclusion The increased serum ASP level in patients with early renal damage in essential hypertension is a good predictor of early renal damage.The combined detection of ASP+IL-6+SBP is better than single detection.

Head and neck malignant tumor is one of the most heterogeneous diseases.The multi-disciplinary team(MDT)is an essen-tial component for personal precise diagnosis,treatment and integrated care management of oncologic diseases including head and neck malignant tumor.MDT clinical practice is also an important teaching mode for head and neck malignant tumors,but it is limited by time and space in actual teaching.An internet visualization platform was constructed based on the Internet,hospital HIS/PACS/LIS/EMR system,medical visualization screen,oral endoscope,remote consultation platform and other accessible audio and video terminals,and has been applied in MDT clinical teaching of head and neck malignant tumors,allowing medical students to participate in MDT through a networked visualization platform.Medical students will achieve deep learning for the most heterogeneous malignant tumor.MDT sup-ported by the internet visualization platform provides a new pathway for clinical medical education.

Objective To provide evidence-based references for the prevention of surgical site infection(SSI)by sum-marizing the best evidence for the prevention of SSI in adult inpatients.Methods The'6S'evidence resource pyramid model was used to systematically search the related evidence in domestic and foreign databases,guideline websites,and academic socie-ty websites from the inception of the database to September 30,2023.Four researchers evaluated the quality of the included guidelines,and two researchers independently evaluated the quality of other types of literature and rated the level of evidence.Results A total of 12 articles were included,including 6 clinical decision making and 6 clinical guidelines.Thirty best items of the evidence were summarized from 7 aspects:diagnosis,clinical symptoms,influencing factors,patient prevention strategies,preventive strategies for medical staff,intraoperative and postoperative treatment,and consultation and education.Conclusion Clinical staff should develop a standardized management plan for infection prevention based on corresponding evidence to reduce the incidence of SSI instead of taking a single measurement.Moreover,they need to formulate a standardized work process for preventing SSI based on the clinical practice and patients'preference.

Objective To observe the correlations of pontine biological indicators on fetal brain median sagittal MRI with gestational week.Methods Data of head MRI of 226 normal fetuses without obvious abnormalities of central nervous system(normal group)and 17 fetuses with abnormalities(abnormal group)at gestational age of 23 to 38 weeks were retrospectively analyzed.Pontine biological indicators based on median sagittal MRI were obtained,including pons anteroposterior diameter(PAD),total pons area(TPA),pontine basal anteroposterior length(AP),pontine basal cranio-caudal length(CC),basis pontis area(BPA)and pontine angle of midbrain(MAP).According to the gestational week,the fetuses of normal group were divided into 8 subgroups.The distributing ranges of pontine biological indicators at different gestational weeks were analyzed,and the correlations of pontine biological indicators with gestational week in normal group were explored,and the developmental status of fetal pons in abnormal group were assessed.Results In normal group,PAD,TPA,AP,CC and BPA all showed linear positive correlation(r=0.887,0.914,0.787,0.866,0.865,all P＜0.001),while MAP was not significantly correlated with gestational week(P＞0.05).Among 17 fetuses in abnormal group,abnormal PAD or TPA was found each in 8 fetuses,abnormal AP was observed in 14,abnormal CC was noticed in 3 and abnormal BPA was found in 11 fetuses.Conclusion Fetal pontine biological indicators such as PAD,TPA,AP,CC and BPA on median sagittal MRI were positively correlated with gestational week,hence being able to be used for evaluating fetal pontine development.

The problems caused by proximal contact loss(PCL)of dental implants have been a mainstream research topic in recent years,and scholars are unanimously committed to analyzing their causes and related factors,aiming to identify solutions to the problems related to PCL.The effects of the anterior component of force(ACF),the lifelong re-molding of the adult craniofacial jaw and alveolar socket,and the osseointegration characteristics of dental implants are the main causes of PCL.On the one hand,the closing movement of the mandible causes the ACF of the tooth to move through the posterior molar cusp.Moreover,drifting between the upper and lower posterior teeth and mandibular anteri-or teeth can cause the anterior teeth of the upper and lower jaws to be displaced labially.On the other hand,reconstruc-tion of the jaw,alveolar socket and tooth root,the forward horizontal force of the masticatory muscles,the dynamic com-ponent of the jaw and the forward force generated by the oblique plane of the tooth cusp can cause the natural tooth to experience near-middle drift.Additionally,natural teeth can shift horizontally and vertically and rotate to accommodate remodeling of the stomatognathic system and maintain oral function.Nevertheless,the lack of a natural periodontal mem-brane during implant osseointegration,the lack of a physiological basis for near-medium drift,the small average degree of vertical motion and the integrated silence of dental implants without the overall drift characteristics of natural teeth increases the probability of PCL.The high incidence of PCL is clearly associated with the duration of prosthesis delivery and the mesial position;but it is also affected by the magnitude of the bite force,occlusion,the adjacent teeth,restora-tion design,implant location,jaw,and patient age and sex.PCL has shown a significant correlation with food impaction,but not a one-to-one correspondence,and did not meet the necessary and sufficient conditions.PCL is also associated with peri-implant lesions as well as dental caries.PCL prevention included informed consent,regular examinations,se-lection of retention options,point of contact enhancement,occlusal splints,and the application of multipurpose digital crowns.Management of the PCL includes adjacent contact point additions,orthodontic traction,and occlusal adjust-ment.Existing methods can solve the problem of food impaction in the short term with comprehensive intervention to seek stable,long-term effects.Symmetric and balanced considerations will expand the treatment of issues caused by PCL.

Objective To explore the potential influencing factors and complex pathways affecting rehabilitation effect for children with autism spectrum disorder(ASD)from the perspective of parental efficacy in doctor-patient communication,and to provide evidence for improving the quality of rehabilitation service for children with ASD. Methods An anonymous face-to-face questionnaire survey was conducted to collect general demographic information of parents of children with ASD at designated rehabilitation institutions in Gansu province.The data included paren-tal efficacy in doctor-patient communication,parental compliance of treatment and children's rehabilitation out-comes were collected.A structural equation model was used to explore the impact mechanism of parental commu-nication efficacy on the rehabilitation outcomes of children with ASD. Results Data from 519 parents at 37 rehabilitation institutions across 13 cities/counties in Gansu province were collect-ed.Significant positive correlations were found between parental efficacy in doctor-patient communication,doc-tor-patient relationships,parental compliance with treatment and rehabilitation outcomes for children with ASD(P＜0.05).Through structural equation model analysis,the standardized direct effect of children with ASD from parents'doctor-patient communication efficacy was 0.151(P=0.023).The mediating effect of doctor-patient rela-tionship and parental compliance with treatment were 0.160(P=0.001)and 0.111(P=0.001),respectively,with a chained mediating effect of 0.035(P=0.001).The pathway"parental efficacy in doctor-patient communica-tion → doctor-patient relationship → ASD child's rehabilitation outcome"accounted for the highest proportion of the total mediating effect,at 52.29%. Conclusion Parental doctor-patient communication efficacy may positively impact on the rehabilitation outcomes of chil-dren with ASD directly,and indirectly through the doctor-patient relationship and parental compliance with treat-ment.Rehabilitation institutions should focus on fostering parental communication skills and enhancing high-quality and humanized rehabilitation services.
