Objective To investigate the situation of mental disability in Hebei province. Methods Based on the survey of the Second National Disabled Sample in Hebei province, the data of mental disability were analysed, including the morbidity, severity, causes, and the service and demand. Results The morbidity of mental disability was higher in the countryside than that in the city (χ2=364.24, P<0.01). The severity of the disabled was more in level 3 or 4 than in level 1 and 2 (χ2=221.16, P<0.01). The genetic disease and brain disease were the major causes to the mental disability. The service did not meet the demand. Conclusion The mental disability was more in the countryside than in the city, with severity of mild to moderate.

Person Centred Planning(PCP) is a life planning approach designed for individuals with disabilities to increase their self-determination ability and improve their independence,which contains some commonly used methods,such as Personal Futures Planning,MAPS,Essential Lifestyle Planning,Whole Life Planning and Planning Alternative Tomorrows with Hope(PATH).It pursues social inclusion and designed to enable people to choose their own supports and services,by reflecting of the individual's personal communication mechanisms and assisting them to outline their needs,wishes and goals,rather than attempting to fit with the existed service systems.However,in the process,some people often adopt the form of this planning approach without the philosophical content.The complete solution of this problem need the active cooperation of relevant agencies even the entire community.

Researchers have long focused on the adaptive behavior,quality of life,dual diagnosis,personality motivation and families of persons with mental retardation,but failed to address virtue and well-being.Unlike even a decade ago,we can now well afford to turn the emphasis to the positive,internal states of those with mental retardation.Using the breakthroughs in positive psychology,these findings such as positive trait or positive experience,can proposes a new research agenda to mental retardation.Mental retardation can play an important role in positive psychology,but it needs the research and data support in future.

This paper reviewed the developments of the conception, epidemiology of intelligence disability, and discussed the classification and rehabilitation.

In view of the evaluation of fundus image segmentation, a new evaluation method was proposed to make up insufficiency of the traditional evaluation method which only considers the overlap of pixels and neglects topology structure of the retinal vessel. Mathematical morphology and thinning algorithm were used to obtain the retinal vascular topology structure. Then three features of retinal vessel, including mutual information, correlation coefficient and ratio of nodes, were calculated. The features of the thinned images taken as topology structure of blood vessel were used to evaluate retinal image segmentation. The manually-labeled images and their eroded ones of STARE database were used in the experiment. The result showed that these features, including mutual information, correlation coefficient and ratio of nodes, could be used to evaluate the segmentation quality of retinal vessel on fundus image through topology structure, and the algorithm was simple. The method is of significance to the supplement of traditional segmentation evaluation of retinal vessel on fundus image.

We report a case of asymptomatic COVID-19 infection in a pregnant woman in the third trimester with good maternal and infant outcomes. The patient was admitted to the Second People's Hospital of Hefei on February 11, 2020, because of a "positive novel coronavirus nucleic acid test result for one day" at 38 weeks of gestation. No abnormality was observed during her previous regular prenatal examinations. A throat swab sample was obtained from the patient four days before admission due to the diagnosis of COVID-19 infection in her husband and sister on the 14^th and 7^th day before her admission, and the new coronavirus nucleic acid test showed positive. The patient reported no discomfort before admission. Chest CT on the 3^rd after admission showed a small amount of bilateral pleural effusion. Irregular contractions occurred three days after admission and labor was considered to be imminent. An emergency cesarean section was performed and the patient delivered a live baby girl. No tests were performed on amniotic fluid, cord blood or placenta for new coronavirus nuclei acid. The patient was isolated from the infant without breastfeeding after surgery. All medical staff involved in the cesarean section were isolated after surgery. Neonatal peripheral blood and nasopharyngeal swabs were collected for the new coronavirus nucleic acid tests on the day of birth and one day of age respectively, and nasopharyngeal swabs and anal suabs were taken at nine days after birth. All test results were negative. The patient recovered well after surgery with stable vital signs. Chest CT on the 8^th after operation showed a small amount of bilateral pleural effusion, while the new coronavirus nucleic acid test results of the pharyngeal swabs were positive on the 11^th and 12^th day after operation. The throat swabs of all medical staff involved in the operation were negative 14 days after the operation. The mother and baby were discharged 14 days after the Cesarean section.

Objective:To establish a prediction model of acute gastrointestinal injury (AGI) above grade II in elderly patients with severe pneumonia, and to evaluate and validate the model internally.Methods:A retrospective analysis was performed on 268 patients aged >65 years with severe pneumonia admitted to the Second People′s Hospital of Hefei from June 2019 to May 2022 (207 cases in the training set and 61 cases in the verification set). Sixteen indicators, including age, sex, underlying disease, pneumonia Severity index (PSI) score, dosage of sedative and analgesic drugs, and mechanical ventilation time of all patients were collected. After logistic regression analysis in the training set, a model was established to predict AGI above grade Ⅱ in elderly patients with severe pneumonia. Receiver operating characteristic (ROC) curve was drawed and correction curve was used to evaluate the reliability of the model. The model was internally validated by validation set data.Results:Among 207 patients with severe pneumonia in the training set, 50 patients developed AGI above grade Ⅱ during treatment. The prediction model was established by logistic regression analysis as follows: When L=Sequential Organ Failure Assessment (SOFA)×0.181+ PSI score×0.066+ propofol dosage×0.607+ reifentanil dosage×1.187, L>19.288, it can be considered that patients with severe pneumonia have a 93.24% chance of developing grade Ⅱ or above AGI. The ROC curve showed that the model was well differentiated, AUC=0.960. H-L test indicated (χ 2=7.39, P=0.496>0.05) the model fit was good. The sensitivity and specificity of the model were 82.00% and 96.82% respectively. AUC=94.58% (sensitivity 81.25%, specificity 93.33%), H-L test indicated ( χ 2=4.51, P=0.808>0.05) the prediction accuracy was 90.16%. Conclusions:The prediction model for AGI after severe pneumonia in elderly patients can be used clinically to help predict the occurrence of AGI in elderly patients with multiple injuries.
