Objective To discuss the clinical value of flat head CT of two-way digital flat angiography system(DSA)in predicting symptomatic intracranial hemorrhage in patients with acute anterior circulation-large vessel occlusion cerebral infarction occurring within 24 hours after operation.Methods A total of 264 patients with acute anterior circulation-large vessel occlusion cerebral infarction,who were admitted to the Shanghai Changhai hospital to receive treatment from January 2020 to January 2023,were selected for this study.Mechanical thrombectomy was carried out in all the patients,and DSA flat head CT examination was performed 24 hours after operation.According to whether the postoperative DSA plate head CT scan showed high-density shadow or not,the patients were divided into observation group(showing high-density shadow,n=176)and control group(showing no high-density shadow,n=88).The clinical data,therapeutic regimen,and intracranial hemorrhage within 24 hours after operation were compared between the two groups.Taking head CT results as the standard,the clinical value of DSA flat head CT scan performed immediately after operation in predicting symptomatic intracranial hemorrhage occurring within 24 hours after operation was evaluated.Results Among the 264 patients with acute anterior circulation-large vessel occlusion cerebral infarction,118 patients developed intracranial hemorrhage within 24 hours after operation,including 24 patients(20.34％)having symptomatic intracranial hemorrhage.No statistically significant differences in clinical data and therapeutic regimen existed between the two groups(P＞0.05).The sensitivity,specificity and accuracy of DSA flat head CT scan performed immediately after operation in predicting intracranial hemorrhage occurring within 24 hours after operation in the observation group were 97.46％,58.22％and 75.76％respectively.The detection rate of symptomatic intracranial hemorrhage occurring within 24 hours after operation in the observation group was higher than that in the control group,the difference between the two groups were statistically significant(P＜0.05).The sensitivity,specificity and accuracy of DSA flat head CT scan performed immediately after operation in predicting symptomatic intracranial hemorrhage occurring within 24 hours after operation were 87.50％,57.48％and 40.15％respectively.The sensitivity,specificity and accuracy of DSA flat head CT scan in predicting the transformation of cerebral hemorrhage were 95.67％,63.12％and 80.23％respectively.Conclusion In patients with acute anterior circulation-large vessel occlusion cerebral infarction,who develop intracranial hemorrhage within 24 hours after mechanical thrombectomy,DSA flat head CT scan performed immediately after operation often shows high-density shadow,which is very helpful in predicting the risk of postoperative intracranial hemorrhage,the clinicians should make an early diagnosis and response to a possible symptomatic intracranial hemorrhage.

Objective To observe the effectiveness and safety of different methods under multi-disciplinary treatment(MDT)model for treating pulmonary arteriovenous malformation(PAVM).Methods MDT were retrospectively performed in 31 patients with PAVM.The effectiveness and safety of interventional therapy,surgical treatment and conservative therapy for PAVM were compared.Results Among 31 cases of PAVM,22 cases underwent interventional therapies(interventional group),4 cases received surgical treatments(surgical group)and 5 cases underwent conservative therapies(conservative group).In interventional group,PAVM was successfully embolized in all 22 cases,with the technical success rate was 100％(22/22).Pleurisy was occurred in 3 cases(3/22,13.64％),while recurrence of PAVM was noticed in 4 cases(4/22,18.18％)during follow-up.No recurrence occurred in interventional group after the second interventional therapies.In surgical group,4 cases were successfully treated with thoracoscopic lobectomy,with the technical success rate of 100％(4/4).No postoperative complication occurred,while recurrence of PAVM was noticed in 2 cases(2/4,50.00％)during follow-up,including 1 case underwent interventional therapy and 1 case underwent conservative therapy.In conservative group,progressive PAVM was observed in 3 cases(3/5,60.00％),including 2 cases who were cured with interventional therapy and 1 case died of stroke after conservative therapy.Conclusion Individualized treatments of PAVM were feasible under MDT model.Compared with surgical treatments and conservative therapies,interventional therapies of PAVM were more effective and relatively safe.

Objective:To observe any effect of family rehabilitation interventions based on digital health management on elderly type 2 diabetes mellitus (T2DM) patients with sarcopenia.Methods:One hundred elderly T2DM patients with sarcopenia who had been discharged from hospital after treatment were divided into an observation group and a control group, each of 50. Both groups continued the diet control and training begun during their hospitalization, but the observation group was additionally provided with family rehabilitation based on digital health management. Before and after 3 months, the glucose and lipid metabolism and sarcopenia of both groups were evaluated with related symptom indexes, and their levels of diabetes self-management were compared.Results:Significant improvement was observed in both groups, but the average glucose and lipid metabolism indexes and sarcopenia-related symptom indexes of the observation group were significantly better than the control group′s averages. Their diabetes self-management was also significantly superior.Conclusion:Family rehabilitation based on digital health management can significantly improve glucose and lipid metabolism and muscle mass in elderly T2DM patients with sarcopenia. Such intervention is worthy of promotion and application in clinical practice.

Objective: To understand the public health emergency response capacity in primary and secondary schools, and to explore the problems and challenges in the prevention and control of public health emergency in primary and secondary schools for specific strategies. Methods: By using the stratified group sampling method, a questionnaire survey on general situation, knowledge, attitude and training, as well as public health emergencies response capacity among 2 988 teachers or leaders responsible for school emergency response in primary and secondary schools from Beijing, Chongqing and Yunnan. Results: Participants varied on their positions, titles, educational background and knowledge accuracy. Higher knowledge accuracy was associated with higher educational background ( χ 2=50.73-203.36, P < 0.05 ). The implementation of regular public health emergency related programs was poorly conducted in high schools (50.0%). Urban schools (42.0%) had higher proportion of qualified health care professionals than rural schools (18.2%), and private schools (48.5%) was higher than public schools (24.7%). The primary challenges included the shortage of guidance from professionals and the lack of related testing equipment (84.91%, 74.03%). Conclusion Although the ability of emergency handling of public health emergencies in schools in the three regions is advancing with the times, there are still many deficiencies, some omissions in the mastery of knowledge. It is suggested to inerease pre service and special training of school health work CDC should strengthen technical guidance and work supervision of infectious disease management in schools.

Objective: To preliminarily develop Health Literacy Scale for pupils, providing a tool for dynamic monitoring and related health literacy research among pupils. Methods: Through policy and literature review, the health literacy evaluation index system of pupils was established. Through two rounds of expert consultation, the evaluation index system and scale item pool of three levels in primary school were formed, and "Evaluation Scale 1.0" was developed. Through two panel discussions, health education experts, teachers and students were invited to provide advices on the content, expression and structure of scale 1.0, turning it into "Evaluation Scale 2.0", and completing the preliminary development of the scale. Results: The health literacy assessment index system of primary school students includes three levels，including level-1 was Grade 1-2, level-2 was Grade 3-4,level-3 was Grade 5-6, covering two level indexes. The scale for primary school students contained five horizontal dimensions and four vertical dimensions. In the Delphi consultation, the response rate was 100%, and the authority coefficient was 0.85. After item selection and modification, the final version of level-1, level-2 and level-3 scales contained 36, 44 and 50 items respectively. Conclusion The development of Health Literacy Evaluation Scale for pupils has high applicability and practical value.

ObjectiveTo investigate the effect of porcine large intestine-processed Dahuang （Radix et Rhizoma Rhei） on defecation in constipation model mice and the possible mechanism. MethodsFifty Kunming mice were randomized to blank group （n=10） and model group （n=40）. Loperamide suspension at the dose of 8 mg/（kg·d） was given by gavage for four consecutive days to establish a model of constipation. The 24 successfully modeled mice were randomly divided into model group， processed Dahuang group， lactulose group， raw Dahuang group， with six mice in each group. Moreover， six randomly selected mice were chosen as control group. Since the fifth day， 8 mg/（kg·d） of loperamide suspension by gavage was given to the model group， processed Dahuang group， raw Dahuang group， and lactulose group； two hours later， the processed and raw Dahuang groups were administered with 0.6 g/（kg·d） of processed and raw Dahuang suspension， respectively， while the lactulose group was given 0.6 g/（kg·d） of latulose suspension， and the blank group and the model group were given 0.2 ml/10 g of distilled water by gavage， all for four days. The general condition， body weight after the last gavage， number of fecal particles within six hours， fecal wet weight， fecal water content ratio， intestinal propulsion rate and colonic histology changes by HE staining of each group were detected. ResultsThe body weight of the mice in the raw Dahuang group was significantly lighter than that in the other groups （P＜0.05 or P＜0.01）. The number of fecal particles， fecal wet weight and intestinal propulsion rate of mice significantly decreased in the model group than in the blank group （P＜0.05 or P＜0.01）. Compared to those in the model group， the number of fecal particles and fecal wet weight in the processed Dahuang group， lactulose group and raw Dahuang group significantly increased， and the fecal water content ratio in the raw Dahuang group increased as well （P＜0.05 or P＜0.01）. Compared to those in the processed Dahuang group， the number of fecal particles and fecal wet weight in the raw Dahuang group decreased， while the fecal water content ratio increased （P＜0.05 or P＜0.01）， and the fecal water content ratio in the lactulose group increased significantly （P＜0.05）. The intestinal propulsion rate in the processed Dahuang group was higher than that in the model group， lactulose group and raw Dahuang group （P＜0.05 or P＜0.01）. Histopathological analysis showed that the colonic crypts and goblet cells in the blank group were normal and clear， and the colonic muscular layer was thicker. The colonic crypts of the mice in the model group were damaged， with reduced goblet cells to varying degrees and changed colonic muscularis. In the lactulose group and raw Dahuang group， part of the crypts were broken， and the goblet cells were damaged to varying degrees， while in the processed Dahuang group， still the colonic tissue structure of the mice was relatively clear， and the colonic crypts and goblet cells were relatively normal， with thickened muscular layer of the colon. ConclusionPorcine large intestine-processed Dahuang could improve defecation in constipation model mice， and reduce the drastic purgation function of raw Dahuang， for which the mechanism may be related to the protection of colon histopathological damage.

ObjectiveTo compare the diagnostic accuracy of five different weighting methods of Chinese medicine syndrome and then analyze their diagnostic efficacy and characteristics， by taking Diagnostic Standard for Type 2 Diabetes Mellitus （T2DM） with Dampeness-heat Syndrome （abbreviated as diagnostic standard） as an example. MethodsData from expert questionnaire on the diagnostic standard and a cross-sectional survey of 1021 patients were collected. The comparative diagnostic test accuracy （CDTA） method was used to calculate the area under the ROC curve （AUC）， area under the PR curve （AUPR）， accuracy （ACC）， sensitivity， and specificity of five commonly used weighting methods in two categories， including knowledge-driven weighting methods （expert scoring synthesis method， analytic hierarchy process， and precedence chart method） and data-driven weighting methods （logistic regression contribution method and entropy weighting method）. ResultsAmong 1021 patients with T2DM， 389 cases were diagnosed as dampness-heat syndrome. The expert scoring synthesis method， analytic hierarchy process method， and precedence chart method were basically consistent in the weight scores of each item. The expert scoring comprehensive method， analytic hierarchy process method， and entropy weighting method have a smaller difference in the weight scores of each item， while there was larger difference in the weight scores of each item of the precedence chart method and the logistic regression contribution method. The AUC （95% CI）， AUPR， ACC， sensitivity， and specifi-city of the expert scoring synthesis method were 0.913 （0.893， 0.932）， 0.851， 0.870， 0.868 and 0.875， respectively； while those of the analytic hierarchy process method were 0.910 （0.890， 0.930）， 0.838， 0.879， 0.848 and 0.896； of the precedence chart method were 0.919 （0.900， 0.937）， 0.858， 0.875， 0.871 and 0.875； of the logistic regression contribution method were 0.867 （0.842， 0.891）， 0.792， 0.853， 0.769 and 0.898； and of the entropy weighting method were 0.895 （0.873， 0.916）， 0.820， 0.869， 0.802 and 0.908. ConclusionThe knowledge-driven weighting methods are better than the data-driven weighting methods in terms of diagnostic efficacy and reflecting expert experience.

ABSTRACT OBJECTIVE To investigate the current situation of pediatric pharmacist-managed clinic in China, and to provide reference for pediatric pharmacist-managed clinic construction and improvement. METHODS Domestic Children's hospitals, Women's & Children's Hospital, and general hospitals with pediatric unit were selected as the survey objects, questionnaires were distributed through the Wenjuanxing Application, and SPSS 26.0 was used to describe the data. The development of pediatric pharmacist-managed clinic, the qualification of visiting pharmacists, the situation of post training and training needs were analyzed. RESULTS A total of 101 valid questionnaires were collected. Pediatric pharmacist-managed clinics had been set up in 55(54.5%) hospitals, of which 35 were independent pharmacists' clinics, and most had well medical document and patient management processes. However, about 70% of hospitals did not charge registration fees, and more than half of hospitals had fewer than 5 patient-visits per day. 85.5% of the hospitals were visited by clinical pharmacists, and about half of them were senior clinical pharmacists with more than 10 years of working experience. But only 3.6% of visiting pharmacists had the right of specific prescription. In 101 hospitals relevant post training for pharmacists had been carried out in 36 hospitals, of which 25 hospitals had set up pharmacist-managed clinic. In addition to pharmaceutical expertise, more than 50% of pharmacists had a strong demand for the improvement of physician-patient communication and problem-solving ability, and 30%-40% of the demand was focused on the collection of medication history, psychological counseling ability, and case-based learning in the pharmacist-managed clinic. CONCLUSION At present, the domestic pediatric pharmacist-managed clinic shows a vigorous development trend, however, there are insufficient registration fees, visits, and post training. Appropriate service methods of pediatric pharmacist-managed clinic should be actively explored, and a pediatric specialized training system for should be well constructed to improve the competency.
