ObjectiveThis paper aims to explore the risk factors for chronic atrophic gastritis （CAG） with turbidity toxin accumulation syndrome and establish a prediction model. MethodsClinical data of 180 patients with CAG who participated in the "clinical study of Xianglian Huazhuo Particles blocking CAG cancer transformation" of Hebei Sheng Zhong Yi Yuan from July 2021 to March 2022 were collected. After confounding factors were controlled by propensity score matching， patients were divided into a training set （namely dev） and a validation set （namely vad） in a seven to three ratio. The risk factors for CAG with turbidity toxin accumulation syndrome in the training set were investigated by using univariate Logistic regression analysis and least absolute shrinkage and selection operator （namely Lasso） regression algorithms. Subsequently， a model， named model 1se， was developed by using the training set data to predict the risk factors for CAG with turbidity toxin accumulation syndrome. The accuracy of the prediction model was assessed by using various methods， including the receiver operating characteristic （ROC） curve， Hosmer-Lemeshow test （H-L）， calibration plot， and decision curve analysis （DCA）. ResultsAge， body mass index （BMI）， family history of cancer， job and life satisfaction， yellow and greasy fur with slippery pulse， and heavy body sensation were independent risk factors of the model. The prediction model showed excellent predictive value for both the training and validation sets. ConclusionThe established prediction model for CAG with turbidity toxin accumulation syndrome has high discrimination and excellent calibration， which could provide an excellent clinical basis for disease diagnosis and individualized treatment of patients.

There are cognitive differences between doctors and patients in the evaluation of doctor-patient relationship. Doctors place more emphasis on evaluation from a professional perspective, including the application of professional knowledge and skills, as well as the evaluation of patient treatment outcomes. While patients pay more attention to meeting their health needs, including the quality and effectiveness of medical services, and the experience of communication and care. This cognitive difference is influenced by factors such as culture, social background, education, information acquisition, etc. To alleviate this difference, it is necessary to strengthen doctor-patient communication and negotiation, strengthen doctor-patient education and interaction, and establish a fair and transparent medical system.

Establishing a targeted and suitable professional healthcare training model for pediatricians at primary level and exploring an effective, sustainable and innovative strategy for talent training are required in caring for children at large. The current study explored the methods and efficacy of " apprenticeship" mode originated from traditional Chinese medicine practice in primary pediatricians training. It is suggested that based on the framework of pediatric alliance, the " apprenticeship" mode could establish a fixed and precise one-to-one teaching mode in a short period, form a close, standard and persistent training system for talented pediatricians, thus effectively improving primary pediatric health care service.

Objective:To investigate the basic information and implementation of medical assistance for children of illness-caused poverty families.Methods:From March through September 2019, a customized questionnaire was used to collect by means of both field survey and on-site verification, the information of the sick children from such families registered on file from 17 counties in 6 provinces. These counties were the first to carry out the assistance pilot work under " Chinese Children Poverty Alleviation by Healthcare Program" . The data so acquired were subject to descriptive analysis.Results:A total of 312 questionnaires were recovered, and the median age of these child patients was 8.54 years. Diseases causing family poverty were mostly those in the circulatory system, nervous system, neoplastic disease of childhood and hematological disease, while unaffordability of medical bills ranked the top challenge when they seek medical services. Hierarchical diagnosis and treatment was made for 251 children: 193(76.89%)of them could be admitted to provincial or lower medical institutions, 43 children needed chronic disease management, and 15 children needed to be admitted by the National Children′s Medical Center for further diagnosis.Conclusions:The assistance for such families in poverty-stricken areas can be upgraded, by such means as disease prevention publicity and education, publicity of healthcare poverty alleviation policy awareness, improvement of medical competency of primary medical institutions and rational application of medical resources.

Objective To investigate the abnormal functional connectivity (FC) between the cores (including sublaterodorsal nucleus (SLD) and ventrolateral periaqueductal gray matter (vlPAG)) and the whole brain in rapid eye movement sleep behavior disorder (RBD) by resting state functional magnetic resonance imaging (rfMRI).Methods A total of 41 subjects recruited in the Department of Neurology,the People's Hospital of Zhengzhou University were enrolled in this study according to international diagnosis criteria,including 20 with idiopathic RBD (iRBD group) and 21 age,sex-matched normal controls (control group).All subjects were examined by Hoehn-Yahr Staging,cognitive tests and rfMRI.Resluts HoehnYahr staging score was 0(0,0) in the iRBD group,which showed no significant difference from that in the control group (0 (0,0),Z =-1.820,P =0.069).The scores of Rey Auditory Verbal Learning Test (AVLT) N1,AVLT N2,Symbol Digital Modalities Test,Rey-Osterrieth Complex Figure Test-Copy were 3.80 ± 1.67,5.10 ± 1.77,33.00(31.25,34.00) and 22.00(20.25,26.00) respectively in the iRBD group,which were significantly lower than that in the control group (4.95 ± 1.28,t =2.482,P =0.017;6.43±1.16,t =2.848,P=0.007;33.00(29.50,35.50),Z=-3.792,P=0.000;35.00(33.00,36.00),Z =-2.351,P =0.019) respectively.The scores of Trail Making Test 1 (86.5 (70.0,100.0))and Trail Making Test 2 (197.0(180.5,211.5)) in the iRBD group were significantly higher than that in the control group (66.0(49.0,91.5),112.0(99.5,173.0) respectively,Z=-2.373,P=0.018;Z =-3.105,P =0.002).Compared with the control group,the FC analysis showed reduced connections from the right SLD to the bilateral cingnlate gyrus (t =-4.173) and bilateral frontal gyrus (t =-2.965(left),-3.662(right)),from the vlPAG to the left precentral-postcentral gyrus(t =3.930),and from the vlPAG to the right frontal gyrus (t =4.141) in the iRBD.There was no statistically significant difference from the left SLD to the whole brain.Conclusion There were abnormal FCs from the SLD and vlPAG to cognitive and motor areas in RBD patients,perhaps leading to clinical RBD symptoms such as cognitive deterioration and movement disorder.
