The community teaching bases play an important role in training of general practice talents. To raise the training quality, the development of their own capacity is crucial, but community medical institutions also need close cooperation with the departments of general practice in medical schools and the higher-level general hospitals. This article discusses the integration model of management, teaching and research in general practice talent training based on the cooperation of community teaching bases with relevant governmental departments, professional societies/associations, general hospitals and medical schools.

Objective To analyze the morphological alterations of corpus callosum in children with spastic cerebral palsy(SCP)using three-dimensional magnetization prepared rapid acquisition gradient echo(3D-MPRAGE)technology and to investigate the correlation between morphological indexes and gross motor function.Methods Sagittal T1WI 3D-MPRAGE data was collected from 136 children with SCP(SCP group)and 132 age-and gender-matched healthy controls(HC)(HC group),and the gross motor function measure-88(GMFM-88)was applied to assess the gross motor function.Independent sample t-test was used to compare the corpus callosum surface area,volume,maximum anterior-posterior diameter,median sagittal area(total area and area of Ⅰ-Ⅴ zone)between the two groups.Partial correlation analysis was performed to calculate the correlation between morphological indexes of the corpus callosum and GMFM-88 with age as a covariate.Results Children under 3 years old,the corpus callosum surface area of the SCP group(3 914.51 mm2±1 207.97 mm2)was lower than that of the HC group(5 725.51 mm2±1 412.66 mm2).The volume of the corpus callosum(6 108.46 mm3±2 803.97 mm3)in the SCP group was lower than that of the HC group(11 297.96 mm3±4 109.02 mm3).Also,the maximum anterior-posterior diameter of the corpus callosum in the SCP group(53.40 mm±6.31 mm)was lower than that of the HC group(57.74 mm±6.04 mm)(all P<0.05).Children over 3 years old,the corpus callosum surface area of the SCP group(4 970.06 mm2±1 191.31 mm2)was lower than that of the HC group(6 372.55 mm2±1 445.59 mm2).The volume of the corpus callosum(8 330.20 mm3±2 888.20 mm3)in the SCP group was lower than that of the HC group(13 599.82 mm3±3 429.81 mm3)(all P<0.05).Partial correlation analysis showed significant correlation between corpus callosum volume,median sagittal area and gross motor score(P<0.01)with age as a covari-ate.Conclusion The 3D-MPRAGE technology can be useful for the comprehensive assessment of morphological alterations of the corpus callosum in SCP.The corpus callosum volume,and median sagittal area may become neuroimaging references for the assess-ment of motor development in cerebral palsy(CP).

ObjectiveTo discuss the effects of Cistanches Herba phenylethanoid glycosides （CHPhGs） on the intestinal mucosal barrier and gut microbiota in alcoholic liver disease （ALD） mice were discussed. MethodThe 36 C57BL/6N female mice were randomly divided normal group， normal group of CHPhGs， model group， and low， medium， and high-dose groups （175， 350， 700 mg·kg^-1） of CHPhGs， with six mice in each group. The ALD mouse model was built using Lieber-Decarli alcohol liquid feed. The normal group and low， medium， and high-dose groups of CHPhGs were given CHPhGs by gavage daily. Serum aspartate aminotransferase aminotransferase （ALT）， alanine aminotransferase （AST）， triglycerides （TG）， and total cholesterol （TC） levels were detected by an automatic biochemical analyzer. Serum tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， lipopolysaccharide （LPS）， lipopolysaccharide-binding protein （LBP）， D-lactic acid （D-LA）， diamine oxidase （DAO）， and LBP of liver were detected by enzyme-linked immunosorbent assay （ELISA）. The levels of TG and TC in the liver were detected by colorimetry. Liver tissue was treated by oil red O and hematoxylin-eosin （HE） staining. The microstructure of jejunum epithelial cells was observed by electron microscope. Jejunum and colon were treated by HE staining and alcian blue-periodate-scheff (AB-PAS) staining staining， and mucin 2 （Muc2） was treated by immunohistochemistry. The intestinal contents of the normal group， normal group of CHPhGs， model group， and high-dose group of CHPhGs were collected and sequenced. ResultThe ALD model was established successfully. Compared with the normal group， the levels of serum ALT， AST， and TG， as well as the levels of liver TG and TC in the model group were significantly increased （P<0.05）. Histopathology showed that compared with the normal group， the liver cells in the model group showed obvious steatosis. Compared with the model group， the levels of serum TG and liver TG and TC in the low， medium， and high-dose groups of CHPhGs decreased significantly （P<0.05）. The serum ALT， AST， TNF-α， IL-1β， LPS， and LBP in the high-dose group of CHPhGs were also significantly decreased （P<0.05）. The number of liver cells with steatosis in the high-dose group of CHPhGs was significantly reduced， and the microvilli structure of jejunum epithelial cells was basically intact. The expression of Muc2 was reduced in the colon， and the gut microbiota of the high-dose group of CHPhGs changed significantly （P<0.05）. Compared with the normal group， the Allobaculum was significantly up-regulated in the model group （P<0.05）. Compared with the model group， the abundance of Akkermansia in the high-dose group of CHPhGs was significantly increased （P<0.01）. The abundance of Akkermansia was negatively correlated with that of Allobaculum （r=-0.701， P<0.01）. ConclusionCHPhGs can reduce the intestinal barrier injury caused by ALD， which may play a protective role by regulating the abundance and structure of Akkermansia and Allobaculum and affecting the homeostasis of intestinal mucus.

Objective: To explore the association between digital devices usage and body weight overestimation in children and adolescents aged 7-18, in order to provide a scientific basis for body weight overestimation prevention in children and adolescents. Methods: Based on the data of the Research Special Project for Public Welfare Industry of Health using stratified cluster sampling method in 2012, a tatal of 40 073 children and adolescents from 7 provinces with complete information were chosen. Ordinal multivariable Logistic regression model estimated the association between digital devices usage and body weight overestimation. Results: A total of 4 276(11.8%) students with overestimation of body weight were detected, who spent >300 min/d time in digital devices(5.12%) than others (3.84%)( χ 2=19.14, P <0.01). Univariate analysis showed that students with time spent on digital devices >300 min/d had a higher risk in overestimation of body weight ( OR=1.36,95%CI=1.18-1.57,P <0.01) compared with students who spent on digital devices≤120 min/d. There was still a significant association after confounder adjustment ( OR=1.28, 95%CI= 1.10-1.48,P <0.05). Stratified analysis showed that the association between digital devices usage and overestimation of body weight were only observed in girls, 11-18 years old and non single child( P <0.05). Conclusion The time usage of digital devices is associated with overestimation of body weight in children and adolescents. It may helpful for children and adolescents to prevent overestimation of body weight by reducing time spent on digital devices.

The patient was a young female who developed dizziness, weakness, blurred vision and other symptoms 7 days after injection of botulinum toxin type A. She was diagnosed with iatrogenic botulism. The symptoms disappeared and the patient was discharged after 8 days of antitoxin treatment. As the application of antitoxin for the treatment of iatrogenic botulism was rarely reported, here we described one case. Combined with literature review, we hope to provide supplementary data for the clinical application of antitoxin.

OBJECTIVE: To summarize clinical predictors and imaging characteristics of critically ill children infected with SARS-CoV-2 Omicron with neurological complications in Shenzhen during the peak of the first round of infections. METHODS: The clinical data of 11 critically ill children with neurological complications infected with SARS-CoV-2 Omicron in Shenzhen Children's Hospital from December 12 to 31, 2022, were retrospectively collected and analyzed. Laboratory test results related to liver parenchymal injury, histiocytic injury, inflammation, and coagulation function were collected, and imaging characteristics including CT and/or magnetic resonance imaging (MRI) were analyzed. The differences in CT/MRI score, acute necrotizing encephalopathy severity scale (ANE-SS) score and total score (CT/MRI score + ANE-SS score) were compared between the two groups with different prognosis during hospitation. RESULTS: Among 11 children, 7 were male and 4 were female. The age ranged from 10 months to 16 years. There were 5 cases of acute necrotizing encephalopathy (ANE) and 6 cases of acute fulminant cerebral edema (AFCE). During hospitalization, 3 patients survived and 8 patients died of multiple organ dysfunction syndrome (MODS), including 2 cases of ANE and 6 cases of AFCE. All cases had fever (> 38.5 centigrade), and 3 cases had ultra-high fever (> 41 centigrade). Within 48 hours of onset, all cases had disorders of consciousness and 9 cases had seizures. The 8 dead children had complications with multisystem involvement, including shock, respiratory failure, disseminated intravascular coagulation (DIC), liver failure, renal failure or myocardial damage, and the laboratory predictors related to hepatocellular injury [alanine aminotransferase (ALT), aspartate aminotransferase (AST)], histocyte injury [creatine kinase (CK), lactate dehydrogenase (LDH)], inflammation [procalcitonin (PCT), interleukin-6 (IL-6), serum ferritin (SF)], coagulation function (D-dimer) and blood glucose (Glu) increased in different quantities, of which PCT was specifically increased in 6 cases with AFCE, PLT was specifically decreased in 3 cases with AFCE, and ALT and LDH were significantly increased in 2 cases with ANE. Imaging analysis showed subarachnoid hemorrhage, basal ganglia and thalamus lesions in all 6 cases with AFCE, while thalamus lesions in all 5 cases with ANE. The ANE-SS score of 8 deceased children ranged from 2 to 7 (of which 6 cases were ≥ 5), and the ANE-SS score of 3 surviving children ranged from 0 to 2. Eight dead children had a CT/MRI score of 1-4 (of which 6 cases were 4), and 3 surviving children had a CT/MRI score of 1-2 (of which 2 cases were 1). The total score of 8 deceased children was 6-10 (of which 6 cases ≥ 8), and 3 surviving children was 1-4. CONCLUSIONS The neurological complications of critically ill children infected with SARS-CoV-2 Omicron in Shenzhen progressed rapidly to ANE and AFCE, with high mortality. High fever (> 40 centigrade), convulsion/disturbance of consciousness, and multiple organ failure were the most common symptoms in ANE and AFCE cases. PCT increased and PLT decreased specifically in AFCE cases. Poor prognosis (death) was more common in age < 4 years old, predictors of ALT, AST, CK, LDH, PCT, D-dimer, Glu, IL-6 increased significantly, PLT decreased significantly. The common imaging feature of ANE and AFCE is the involvement of dorsal thalamus, a new imaging sign of AFCE (subarachnoid hemorrhage) was found. The higher the ANE-SS score, CT/MRI score and total score, the greater the risk of death.

Objective:To explore status and influencing factors of medication deviation in elderly patients with brain infarction during the hospital-family transition, and to explore the relationship between medication deviation and adverse drug events.Methods:From November 2021 to May 2022, 218 elderly patients with brain infarction from Neurology Department of the First Affiliated Hospital of Chengdu Medical College were selected as the research objects by the convenience sampling method. General data questionnaire and Self-Efficacy for Appropriate Medication Use Scale were used to investigate patients. One month after discharge, patients were investigated by telephone using Medication Discrepancy Tool and Morisky Medication Adherence Scale with Eight-Item, and the incidence of adverse drug events was collected. Logistic regression analysis was used to explore the influencing factors of medication deviation. Spearman correlation analysis was used to investigate the correlation between adverse drug events and medication deviation. A total of 218 questionnaires were distributed in this study, and 207 valid questionnaires were effectively recovered, with an effective recovery rate of 95.0%.Results:The incidence of medication deviation in elderly patients with brain infarction was 48.8% (101/207) . Logistic regression analysis results showed that hypertension, stroke severity, medication compliance and medication quantity were the influencing factors of medication deviation ( P<0.05) . Spearman correlation analysis results showed that adverse drug events were positively correlated with medication deviation ( r=0.234, P<0.01) . Conclusions:The incidence of medication deviation in elderly patients with brain infarction during the hospital-family transition was higher. Hypertension, stroke severity, medication compliance and medication quantity were the influencing factors of medication deviation. Medical staff should formulate targeted intervention measures based on the influencing factors of medication deviation, so as to reduce the incidence of medication deviation.
