Therefore, we recruited the parents/caregivers of 204 ASD cases, 71 ID cases aged 6–18 years from special education schools, and 402 typically developing(TD) children in the same age span from a communitybased population to complete the ASRS and SRS. The results showed that the ID group scored significantly lower on total and subscale scores than the ASD group on both scales(P \ 0.05) but higher than TD children(P \ 0.05).Receiver operating characteristic analyses demonstrated a similar fair performance in discriminating ASD from ID with the ASRS(area under the curve(AUC) = 0.709,sensitivity = 77.0%, specificity = 52.1%, positive predictive value(PPV) = 82.2%) and the SRS(AUC = 0.742,sensitivity = 59.8%, specificity = 77.5%, PPV = 88.4%).The results showed that individuals with ID had clear autistic traits and discriminating ASD from ID cases was quite challenging, while assessment tools such as ASRS and SRS, help to some degree.展开更多

However, data on its prevalence in China are largely missing. Here, we assessed the suitability of the modi？ed Chinese version of a newly-developed ASD screening tool, the Modi？ed Chinese Autism Spectrum Rating Scales（MC-ASRS） in screening for ASD in Chi nese children aged 6–12 years, through comparison with the Social Responsiveness Scale（SRS） that has been widely used for ASD screening. We recruited the par ents/caregivers of 1588 typically-developing children and190 children with ASD aged 6–12 years to complete the MC-ASRS and SRS, and evaluated the validity of both scales in discriminating children with ASD from those developing typically. The results showed that MC-ASRSperformed as well as SRS in sensitivity, speci？city, and area-under-the-curve（both [0.95） in receiver operating characteristic analysis, with a fair false-negative rate.These results suggest that MC-ASRS is a promising tool for screening for children with ASD in the general Chinese population.展开更多

Participants were recruited from Shanghai,Harbin, Guangzhou, and Changsha, China, and their parents and teachers were invited to complete the Chinese Parent version and the Teacher version of the ASRS. In both versions, boys had signi？cantly higher sub-scale scores and total score（T-score） by 1–3 and 4–5 points respectively, than girls（both P ／ 0.001）. Age had weak correlations with some sub-scores and the T-score（r ranged from-0.1859 to 0.0738）, and some reached signi？cance（P ／ 0.03）. The correlations appeared stronger and were more common in females. The T-score based on Chinese norms ideally correlated with the score based on the United States norms in boys and girls for both versions.Norms for the Chinese version of the ASRS for children aged 6–12 years are proposed and may be helpful for screening individuals with autism spectrum disorders from the general population of children.展开更多

Ten college female students aged about 20 were chosen as the subjects, who have participated a preliminary training on subjective prickle evaluation. The prickle of a range of 9 light-weight worsted woven wool and wool blend fabrics and a cotton fabric were tested by using a 1 - 5 rating scale and using a 0 - 10 rating scale respectively at different test parts of body respectively such as forearm, upper arm ball and neck back. The test results were statistically analyzed. It is found that there is a significant correlation coefficient between the evaluation results of using the 1 - 5 rating scale and of using the 0- 10 rating scale. It is also found that there are highly significant correlation coefficients between the evaluation results of using the forearm prickle test and the neck back prickle test, between the evaluation results of using the neck back prickle test and the upper arm ball prickle test, and between the evaluation results of using the forearm prickle test and the upper arm ball prickle test. It is suggested that the forearm prickle test is preferable in evaluating fabric-evoked prickle for its convenience and sensitivity.展开更多

Methods： Probable AD patients（118 cases） diagnosed according to NINCDS-ADRDA criteria and the normal controls（100 cases） were examined with a battery of neuropsychological tests and the dementia severity of AD patients was determined with clinical dementia rating （CDR）. Changed neuropsychological characteristics of different AD dementia severities were analyzed. The discriminant analysis and ROC curve analysis were perfomed to analyze the specificity, the sensitivity, and the general accuracy of various dementia rating scales in the diagnosis of AD, and the area under the ROC curve. Results： The total cognition function in mild （CDR = 1 ）, moderate（CDR = 2） and severe stages（CDR=3） of AD had an obvious trend of continuous decline, with the MMSE values 17.44±2.64, 13.90±4.32, and 5.50 ± 3.90 respectively. The trend of decline of the verbal fluency function in AD was same as that of total cognition function. The visuospatial function was reduced in early stage of AD （CDR = 1 ） and completely lost in moderate and severe AD. Delay memory function began to show decline in the early stage of AD, and the decline turned apparent in moderate and severe AD. Immediate memory function showed unchanged in early stage of AD, while showed decline in moderate AD, and the decline became very quick in severe AD. The impairment of daily living ability and social activity function developed with the severity degree of AD. But the decline of social activity function was very quick in moderate stage of AD. In general, the leading scale to diagnose AD was FOM, followed by RVR, POD, MMSE, BD,ADL and DS. When MMSE was combined with one or more of FOM, RVR, BD, DS, the general accuracy in distinguishing AD from the normal controls was improved. Conclusion： Neuropsychological test is useful in the diagnosis of AD, especially in the early stage. The validity is improved when dementia rating scales are combined correctly.展开更多

After one oil extraction, water injection is needed for secondary extraction. With a large amount of calcium and magnesium ions in the water, which is easy to form a large amount of insoluble scale, its formed barium sulfate and strontium sulfate scale are more difficult to handle than carbonate scale. In order to reduce the difficulty of oil production work, this paper mainly targeted the sulfate scale for experiments, and prepared the scale retardant agent CQC-1. Through orthogonal experimental screening, the mass ratio of itaconate acid:methacrylic acid:AMPS:sodium acrylic sulfonate was 2:1:1:1, increase the amount of evocating agent was 8% and the reaction time was 4h, the sulfate scale inhibitor synthesized at the temperature of 80°C had the best performance. Using scale resistance rate, degradation and salt-resistance, the experimental results showed that the scale resistance rate of CQC-1 reached 90.46%. In the four-week degradation experiment, the degradation rate reached over 71% and was maintained by 80.65% at 150°C, while the scale resistance rate still reached 80.35% in simulated saline. It has excellent scale resistance, temperature resistance, salt-resistance and degradation, and has good development prospects.展开更多

However, it is not yet known whether electroencephalography can predict development of post-cerebral infarc- tion depression. A total of 321 patients with ischemic stroke underwent electroencephalography and Hamilton Depression Rating Scale assessment to analyze the relationship between electroencephalography and post-cerebral infarction depression. Our results show that electroencephalograms of ischemic stroke patients with depression exhibit low-amplitude alpha activity and slow theta activity. In con- trast, electroencephalograms of ischemic stroke patients without depression show fast beta activity and slow delta activity. ＂Ihese findings confirm that low-amplitude alpha activity and slow theta activity can be considered as independent predictors for post-cerebral infarction depression.展开更多

文摘The Autism Spectrum Rating Scale(ASRS) and the Social Responsiveness Scale(SRS) have been widely used for screening autism spectrum disorder(ASD) in the general population during epidemiological studies, but studies of individuals with intellectual disability(ID) are quite limited. Therefore, we recruited the parents/caregivers of 204 ASD cases, 71 ID cases aged 6–18 years from special education schools, and 402 typically developing(TD) children in the same age span from a communitybased population to complete the ASRS and SRS. The results showed that the ID group scored significantly lower on total and subscale scores than the ASD group on both scales(P \ 0.05) but higher than TD children(P \ 0.05).Receiver operating characteristic analyses demonstrated a similar fair performance in discriminating ASD from ID with the ASRS(area under the curve(AUC) = 0.709,sensitivity = 77.0%, specificity = 52.1%, positive predictive value(PPV) = 82.2%) and the SRS(AUC = 0.742,sensitivity = 59.8%, specificity = 77.5%, PPV = 88.4%).The results showed that individuals with ID had clear autistic traits and discriminating ASD from ID cases was quite challenging, while assessment tools such as ASRS and SRS, help to some degree.

文摘The reported prevalence of autism spectrum disorder（ASD） has been increasing rapidly in many parts of the world. However, data on its prevalence in China are largely missing. Here, we assessed the suitability of the modi？ed Chinese version of a newly-developed ASD screening tool, the Modi？ed Chinese Autism Spectrum Rating Scales（MC-ASRS） in screening for ASD in Chi nese children aged 6–12 years, through comparison with the Social Responsiveness Scale（SRS） that has been widely used for ASD screening. We recruited the par ents/caregivers of 1588 typically-developing children and190 children with ASD aged 6–12 years to complete the MC-ASRS and SRS, and evaluated the validity of both scales in discriminating children with ASD from those developing typically. The results showed that MC-ASRSperformed as well as SRS in sensitivity, speci？city, and area-under-the-curve（both [0.95） in receiver operating characteristic analysis, with a fair false-negative rate.These results suggest that MC-ASRS is a promising tool for screening for children with ASD in the general Chinese population.
文摘BACKGROUND Autism is the most common clinical developmental disorder in children.The childhood autism rating scale(CARS)and autistic autism behavior checklist(ABC)are the most commonly used assessment scales for diagnosing autism.However,the diagnostic validations and the corresponding cutoffs for CARS and ABC in individuals with suspected autism spectrum disorder(ASD)remain unclear.Furthermore,for suspected ASD in China,it remains unclear whether CARS is a better diagnostic tool than ABC.Also unclear is whether the current cutoff points for ABC and CARS are suitable for the accurate diagnosis of ASD.AIM To investigate the diagnostic validity of CARS and ABC based on a large Chinese sample.METHODS A total of 591 outpatient children from the ASD Unit at Beijing Children’s Hospital between June and November 2019 were identified.First,the Clancy autism behavior scale(CABS)was used to screen out suspected autism from these children.Then,each suspected ASD was evaluated by CARS and ABC.Receiver operating characteristic(ROC)curve analysis was used to compare diagnostic validations.We also calculated the area under the curve(AUC)for both CARS and ABC.RESULTS We found that the Cronbach alpha coefficients of CARS and ABC were 0.772 and 0.426,respectively.Therefore,the reliability of the CARS was higher than that of the ABC.In addition,we found that the correlation between CARS and CABS was 0.732.Next,we performed ROC curve analysis for CARS and ABC,which yielded AUC values of 0.846 and 0.768,respectively.The cutoff value,which is associated with the maximum Youden index,is usually applied as a decision threshold.We found that the cutoff values of CARS and ABC were 34 and 67,respectively.CONCLUSION This result indicated that CARS is superior to ABC in the Chinese population with suspected ASD.

文摘This study aimed to establish norms for the modi？ed Chinese version of the Autism Spectrum Rating Scale（ASRS）. Participants were recruited from Shanghai,Harbin, Guangzhou, and Changsha, China, and their parents and teachers were invited to complete the Chinese Parent version and the Teacher version of the ASRS. In both versions, boys had signi？cantly higher sub-scale scores and total score（T-score） by 1–3 and 4–5 points respectively, than girls（both P ／ 0.001）. Age had weak correlations with some sub-scores and the T-score（r ranged from-0.1859 to 0.0738）, and some reached signi？cance（P ／ 0.03）. The correlations appeared stronger and were more common in females. The T-score based on Chinese norms ideally correlated with the score based on the United States norms in boys and girls for both versions.Norms for the Chinese version of the ASRS for children aged 6–12 years are proposed and may be helpful for screening individuals with autism spectrum disorders from the general population of children.
文摘This article reviews the constructs of stress, appraisal, coping, according to a transactional perspective, and executive function, and presents a stress control rating scale (ECOSTRESS), which design is founded in these constructs. This psychometric tool is useful in the assessment of cognitive control of stress, correlated with the function of dorsolateral prefrontal cortex. It has been validated for its use in the assessment of Portuguese people in situations of stress related to unemployment and economic insufficiency. Also, within the context of the cognitive control of stress, it is highlighted the usefulness of low resolution brain electromagnetic tomography (LORETA).
文摘The effect of rating scales and test parts of body on the fabric-evoked prickle evaluation results are studied by carrying out subjective evaluation tests under controlled environment conditions （24 4±1）℃, （65 =l= 5） %RH. Ten college female students aged about 20 were chosen as the subjects, who have participated a preliminary training on subjective prickle evaluation. The prickle of a range of 9 light-weight worsted woven wool and wool blend fabrics and a cotton fabric were tested by using a 1 - 5 rating scale and using a 0 - 10 rating scale respectively at different test parts of body respectively such as forearm, upper arm ball and neck back. The test results were statistically analyzed. It is found that there is a significant correlation coefficient between the evaluation results of using the 1 - 5 rating scale and of using the 0- 10 rating scale. It is also found that there are highly significant correlation coefficients between the evaluation results of using the forearm prickle test and the neck back prickle test, between the evaluation results of using the neck back prickle test and the upper arm ball prickle test, and between the evaluation results of using the forearm prickle test and the upper arm ball prickle test. It is suggested that the forearm prickle test is preferable in evaluating fabric-evoked prickle for its convenience and sensitivity.
文摘In this technical note,a novel rating scale(abdominal integral index)was introduced for assessing the conditions of the working laparoscopic space based on linear measurements to select the optimal one or two-stage surgical treatment for super-obesity.Patients with the same height and similar BMI values had different rating scale scores,reflecting different conditions of laparoscopic bariatric surgery.The rating scale helps surgeons and patients make a safe option for surgery,depending on the experience of the surgeon and technical laparoscopic conditions.
文摘Objective： To study the significance of dementia rating scales in the diagnosis of Alzheimer＇ s disease（AD）. Methods： Probable AD patients（118 cases） diagnosed according to NINCDS-ADRDA criteria and the normal controls（100 cases） were examined with a battery of neuropsychological tests and the dementia severity of AD patients was determined with clinical dementia rating （CDR）. Changed neuropsychological characteristics of different AD dementia severities were analyzed. The discriminant analysis and ROC curve analysis were perfomed to analyze the specificity, the sensitivity, and the general accuracy of various dementia rating scales in the diagnosis of AD, and the area under the ROC curve. Results： The total cognition function in mild （CDR = 1 ）, moderate（CDR = 2） and severe stages（CDR=3） of AD had an obvious trend of continuous decline, with the MMSE values 17.44±2.64, 13.90±4.32, and 5.50 ± 3.90 respectively. The trend of decline of the verbal fluency function in AD was same as that of total cognition function. The visuospatial function was reduced in early stage of AD （CDR = 1 ） and completely lost in moderate and severe AD. Delay memory function began to show decline in the early stage of AD, and the decline turned apparent in moderate and severe AD. Immediate memory function showed unchanged in early stage of AD, while showed decline in moderate AD, and the decline became very quick in severe AD. The impairment of daily living ability and social activity function developed with the severity degree of AD. But the decline of social activity function was very quick in moderate stage of AD. In general, the leading scale to diagnose AD was FOM, followed by RVR, POD, MMSE, BD,ADL and DS. When MMSE was combined with one or more of FOM, RVR, BD, DS, the general accuracy in distinguishing AD from the normal controls was improved. Conclusion： Neuropsychological test is useful in the diagnosis of AD, especially in the early stage. The validity is improved when dementia rating scales are combined correctly.
文摘Objective:In order to improve the quality of life of patients more effectively,this paper introduces the types and usages of scales for screening mild cognitive dysfunction after stroke and provides a basis for early identification of mild cognitive impairment.Methods:Read,analyze,summarize,and sort out relevant literature.Results:The mild cognitive impairment assessment scales are broadly divided into two categories:the comprehensive rating scales and the special assessment scales.There are 7 comprehensive assessment scales for the comprehensive rating scales,among which the Mini-mental State of Examination and the Montreal Cognitive Assessment Scale are the most widely used.The special assessment scales are mainly evaluated by the symptoms of cognitive dysfunction and can be divided into five types.Conclusion:Early diagnosis and intervention in patients with cognitive dysfunction will help improve the prognosis of patients.Each assessment scale has its advantages and limitations in both sensitivity and discrimination.Effective use of appropriate scales to diagnose cognitive dysfunction and to screen early,to prevent early,to treat early can effectively improve the quality of life of elderly patients.

文摘Most of the oil wells enter the middle and late stages of extraction. After one oil extraction, water injection is needed for secondary extraction. With a large amount of calcium and magnesium ions in the water, which is easy to form a large amount of insoluble scale, its formed barium sulfate and strontium sulfate scale are more difficult to handle than carbonate scale. In order to reduce the difficulty of oil production work, this paper mainly targeted the sulfate scale for experiments, and prepared the scale retardant agent CQC-1. Through orthogonal experimental screening, the mass ratio of itaconate acid:methacrylic acid:AMPS:sodium acrylic sulfonate was 2:1:1:1, increase the amount of evocating agent was 8% and the reaction time was 4h, the sulfate scale inhibitor synthesized at the temperature of 80°C had the best performance. Using scale resistance rate, degradation and salt-resistance, the experimental results showed that the scale resistance rate of CQC-1 reached 90.46%. In the four-week degradation experiment, the degradation rate reached over 71% and was maintained by 80.65% at 150°C, while the scale resistance rate still reached 80.35% in simulated saline. It has excellent scale resistance, temperature resistance, salt-resistance and degradation, and has good development prospects.

文摘BACKGROUND Peroral endoscopic esophageal myotomy(POEM)is an innovative,minimally invasive endoscopic technique that has been widely adopted and recognized for the clinical management of achalasia because of its advantages of minimal trauma and rapid recovery.Nevertheless,clinical data have indicated that approximately 67%of patients experience esophageal pain after POEM.This high prevalence of pain not only affects patients’post-POEM recovery experience and quality of life but also presents challenges to its clinical implementation.Therefore,it is urgently necessary to explore effective intervention strategies.AIM To accurately determine the incidence of post-POEM pain and to comprehensively investigate the potential risk factors for the development of post-POEM pain.METHODS In this study,123 patients who were clinically diagnosed with achalasia and who underwent POEM were included.Baseline demographic characteristics,post-POEM numerical rating scale(NRS)pain scores,and anesthesia/surgery-related parameters were systematically collected.Patients were categorized into a pain group and a non-pain group on the basis of whether the NRS score exceeded 4 at 12 hours post-POEM.Univariate and multivariate logistic regression analyses were conducted to identify independent risk factors associated with post-POEM pain.RESULTS On the basis of the predefined inclusion and exclusion criteria,123 eligible patients were enrolled.After adjusting for confounding factors,stepwise multivariate logistic regression analysis revealed that the preoperative Eckardt score[odds ratio(OR)=1.317,95%confidence interval(95%CI):0.992-1.748,P=0.057]and preoperative anxiety status(OR=5.195,95%CI:1.691-15.959,P=0.004)were independent risk factors for post-POEM pain.Our multifactor model exhibited robust predictive ability for postoperative pain following POEM,with an area under the receiver operating characteristic curve of 0.760(95%CI:0.661–0.859).CONCLUSION Patients with achalasia who underwent POEM presented a high prevalence of post-POEM pain,which was moderate or severe in 26.8%of these patients.After adjusting for confounding factors,multivariate analysis revealed that preoperative anxiety and a higher Eckardt score were independent risk factors for post-POEM pain.
文摘BACKGROUND Traditional postoperative nursing methods implemented after laparoscopic hepatectomy often leads to slow patient recovery.As a new nursing mode,enhanced recovery after surgery(ERAS)has been widely used in the peri-and postoperative care of patients.However,its effects after laparoscopic hepatectomy remains unclear.AIM To explore the influence of nursing under the ERAS concept on time to first ambulation and complications after laparoscopic hepatectomy.METHODS Data from 119 patients,who underwent laparoscopic hepatectomy for various indications between January 2020 and March 2025,were divided into 2 groups according to nursing mode:Observation[nursing based on the ERAS concept(n=59)],and control[basic nursing(n=60)].Time to first ambulation,complications,length of hospital stay,and numerical rating scale(NRS)scores were compared between the groups.Statistical analysis was performed using SPSS version 26.0(IBM Corp.,Armonk,NY,United States).Differences with P<0.05 were considered statistically significant.RESULTS Findings indicated that after post-nursing intervention,the observation group experienced significantly sooner initial discharge times and shorter hospital stays than the control group(P<0.05).The NRS score of the observation group was lower than that of the control group(P<0.05).The observation group experienced a significantly lower incidence of postoperative complications than the control group(P<0.05).CONCLUSION Operating room nursing based on the ERAS concept significantly shortens the time to first ambulation,reduces the incidence of postoperative complications,and improves patient quality of life after laparoscopic hepatectomy.

文摘Electroencephalography is a sensitive indicator for measuring brain condition, and can reflect early changes in brain function and severity of cerebral ischemia. However, it is not yet known whether electroencephalography can predict development of post-cerebral infarc- tion depression. A total of 321 patients with ischemic stroke underwent electroencephalography and Hamilton Depression Rating Scale assessment to analyze the relationship between electroencephalography and post-cerebral infarction depression. Our results show that electroencephalograms of ischemic stroke patients with depression exhibit low-amplitude alpha activity and slow theta activity. In con- trast, electroencephalograms of ischemic stroke patients without depression show fast beta activity and slow delta activity. ＂Ihese findings confirm that low-amplitude alpha activity and slow theta activity can be considered as independent predictors for post-cerebral infarction depression.

文摘Acupuncture has been shown to lessen the inflammatory reaction after acute spinal cord injury and reduce secondary injury.However,the mechanism of action remains unclear.In this study,a rat model of spinal cord injury was established by compressing the T8-9 segments using a modified Nystrom method.Twenty-four hours after injury,Zusanli（ST36）,Xuanzhong（GB39）,Futu（ST32）and Sanyinjiao（SP6）were stimulated with electroacupuncture.Rats with spinal cord injury alone were used as controls.At 2,4 and 6 weeks after injury,acetylcholinesterase（ACh E）activity at the site of injury,the number of medium and large neurons in the spinal cord anterior horn,glial cell line-derived neurotrophic factor（GDNF）m RNA expression,and Basso,Beattie and Bresnahan locomotor rating scale scores were greater in the electroacupuncture group compared with the control group.These results demonstrate that electroacupuncture increases ACh E activity,up-regulates GDNF m RNA expression,and promotes the recovery of motor neuron function in the anterior horn after spinal cord injury.
