Familiarity and strangeness: the ethnographic method in the initial training of physical education students / Familiaridade e estranhamento: o método etnográfico na formação inicial de estudantes de educação física

ABSTRACT If we want - as the current didactic discussion requires - to further consolidate the figures of didactic thought from the "Post-Renewal Movement"1 era, which manifest themselves in a didactic, critical-emancipatory concept open to experience, then we need to consider how future Physical Education teachers can be qualified to this end. This is not an easy process, as Physical Education students begin their studies with a concept that is familiar to them, the concept of sport. This sporting concept is characterized by an "enclosure" of content, of methodology, and an institutional "enclosure". This essay presents a teaching strategy on how future Physical Education teachers can be encouraged to "open themselves" to new ways of thinking as part of their studies. An ethnographic approach is proposed, in which the aim is to learn to question the "familiar", the "self-evident". "Strangeness" methods are suitable for this purpose. We present 5 steps that can lead students to learn to distance themselves from the "familiar", the biographically incorporated sporting concept. We understand that only when this distancing is successful, according to the hypothesis, will students be able to structure didactic ideas from the "Post-Renewal Movement" era, and plan and implement physical education classes open to experience.

RESUMO Se quisermos, como exige a atual discussão didática, consolidar ainda mais as figuras do pensamento didático da era do "Pós-Movimento Renovador"1, que se manifestam em um conceito didático aberto à experiência e crítico-emancipatório, então precisamos considerar como os futuros professores de Educação Física podem ser qualificados para isso. Este não é um processo fácil porque os acadêmicos de Educação Física iniciam os seus estudos com um conceito que lhes é familiar, o conceito de esporte. Este conceito esportivo caracteriza-se pelo "fechamento" de conteúdo, de metodologia e um "fechamento" institucional. Este ensaio apresenta uma estratégia didática de como os futuros professores de Educação Física podem ser estimulados a se "abrirem" a novas formas de pensar como parte dos seus estudos. Propõe-se uma abordagem etnográfica em que se pretende aprender a questionar o "familiar", o "auto evidente". Métodos de "estranhamento" são adequados para isso. Apresentamos 5 passos que podem levar os acadêmicos a aprenderem a se distanciar do "familiar", do conceito esportivo biograficamente incorporado. Entendemos que somente quando esse distanciamento for bem-sucedido, segundo a hipótese, os estudantes poderão estruturar ideias didáticas da era do "Pós-Movimento Renovador" e planejar e implementar aulas de educação física abertas à experiência.

Agrobiological evaluations of newly introduced grapes varieties under climatic conditions of the south of Kazakhstan / Avaliações agrobiológicas de variedades de uvas recém-introduzidas sob as condições climáticas do sul do Cazaquistão

Variety assortment enhancement is a normal task that involves enhancing the assortment's quality and upgrading varieties. The findings of a research of imported grape varieties in the southeast of Kazakhstan, namely in the Almaty region's bottom-mountain zone, are presented in this article. The onset and conclusion of the main phenological phases of a grape plant throughout the vegetative period were directly influenced by the climatic and meteorological conditions of this district. In comparison to the recognized variety Almaty early-maturing, it has been proven that types Priusadebny, Iyulsky, and Kuibyshevsk early-maturing have a high degree of eyes wintering buds and may provide a high-quality crop in this location.

As descobertas de uma pesquisa de variedades de uvas importadas no sudeste do Cazaquistão, ou seja, na zona de base da montanha da região de Almaty, são apresentadas neste artigo. O início e a conclusão das principais fases fenológicas de uma videira ao longo do período vegetativo foram diretamente influenciados pelas condições climáticas e meteorológicas deste distrito. Em comparação com a variedade reconhecida Almaty de maturação precoce, foi comprovado que os tipos Priusadebny, Iyulsky e Kuibyshevsk de maturação precoce têm um alto grau de gomos de inverno de olhos e podem fornecer uma safra de alta qualidade neste local.

Fitting Degrees of Animal Models of Diarrhea-irritable Bowel Syndrome with Clinical Characteristics of Western Medicine and Traditional Chinese Medicine / 中国实验方剂学杂志

Diarrhea-irritable bowel syndrome （IBS-D） is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated， effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine （TCM） and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D， we discovered that rats were the preferred animals for modeling， and the models were mainly induced by single factors， double factors， or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition， the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency， and few models were established for the syndromes of spleen-kidney Yang deficiency， spleen-stomach dampness-heat， spleen deficiency and dampness excess， and cold and heat in complexity. Therefore， it is essential to improve the existing or develop new animal models of IBS-D in the future， so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

Characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma(PACG).METHODS: A total of 48 first-degree relatives of PACG patients aged 40-60 who were treated in the Affiliated Eye Hospital of Nanchang University from September 2020 to October 2022 were selected as the observation group. Additionally, 40 cases(40 eyes)of healthy individuals without glaucoma and family history of glaucoma at the same age group were collected as the control group. They were divided into younger group(40-49 years old)and elder group(50-60 years old). All subjects were examined with ultrasound biomicroscopy(UBM)and were measured using camera measure software. The parameters mainly included anterior chamber depth(ACD), anterior chamber area(ACA), anterior chamber width(ACW), anterior segment depth(ASD), angle open distance(AOD500), trabecular iris angle(TIA), trabecular iris area(TISA500), lens vault(LV), iris curve(IC), iris thickness(IT500), scleral ciliary process angle(SCPA), and iris ciliary process distance(ICPD).RESULTS: ACD, ACA, AOD500, TISA500 and TIA in the observation group were lower than those of the control group, and LV and IC were higher than those of the control group(all P<0.05). ACD, ACA, AOD500, TISA500, and TIA of the elder group were lower than those in the age-matched control group, while LV and IC were larger than those of the age-matched control group(all P<0.05). ACD, AOD500, TISA500, and TIA of the younger observation group were smaller than those of the age-matched control group, but LV and IC were significantly larger than those of the age-matched control group(all P<0.05). ACD, ACA, AOD500, TISA500 and TIA of the elder observation group were significantly lower than those of the younger observation group, and LV and IC were significantly larger than those of the younger observation group(all P<0.05). There was a difference in the distribution of ACD between the observation group and the control group(P<0.05), and the proportion of moderate to severe shallow anterior chambers was 10 times that of the control group. Correlation analysis showed that TISA500 was positively correlated with ACD and ACA, and negatively correlated with LV and IC, and TISA500 was mainly influenced by LV. IC had a positive correlation with LV and a negative correlation with ACD and ACA.CONCLUSION: First-degree relatives of PACG with normal axial length have a high risk of angle closure. The anterior segment structures of first-degree relatives of PACG are more crowded than normal individuals, and the lens forward shift may be the initial influencing factor for narrow angle.

Meta-analysis of the efficacy of invisible orthodontic appliances for maxillary molar distalization in adult patients / 口腔疾病防治

Objective@#To evaluate the clinical efficacy of invisible orthodontic appliances without brackets for the distal movement of maxillary molars to improve the ability of orthodontists to predict treatment outcomes.@*Methods@#Web of Science, Cochrane Library, Embase, PubMed, Wanfang Database, CNKI Database, and VIP Database were searched for studies investigating the efficacy of invisible orthodontic appliances for distal movement of maxillary molars in adult patients and published from database inception to August 1, 2023. A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.

Animal Models of Ovarian Cancer Based on Characteristics of Clinical Symptoms of Traditional Chinese and Western Medicine / 中国实验方剂学杂志

ObjectiveOvarian cancer is the third most common gynecologic cancer worldwide， with the second highest mortality rate among gynecologic cancers， and age-standardized rates are gradually increasing in many low- and middle-income countries. At present， its etiology and pathogenesis are not clear. There are no obvious symptoms in the early stage， and when the symptoms become obvious， it often indicates the advanced stage. The 5-year survival rate of the advanced stage is only 17%， which poses a great threat to women's health. Therefore， an in-depth study of the etiology and pathogenesis of ovarian cancer is very important to the exploration of prevention and treatment methods for ovarian cancer. Based on the clinical characteristics of ovarian cancer in traditional Chinese and Western medicine， and combined with the existing evaluation methods of animal models， this study evaluated the animal model of ovarian cancer， and provided analysis and suggestions. MethodThis study searched China National Knowledge Infrastructure （CNKI）， Wanfang data， VIP information database， and PubMed database using the keywords "ovarian cancer" and "animal model"， excluded the articles that did not meet the criteria， and then classified the remaining studies. Combined with the clinical diagnostic criteria of Western medicine and traditional Chinese medicine syndrome differentiation， the related indicators of ovarian cancer animal models were assigned and the degree of agreement was evaluated. ResultThe use of the transplanted animal model exhibited the highest frequency， followed by that of the induced model. The degree of agreement of traditional Chinese medicine for each model was lower than that of Western medicine. The induced ovarian cancer model had a high degree of clinical agreement and was similar to human ovarian cancer in terms of tumor growth pattern， disease progression and complications， which is an ideal animal model of ovarian cancer. Although this animal model can simulate the etiology and pathogenesis of ovarian cancer to a certain extent and reflect some indicators of traditional Chinese and Western medicine， it lacks differentiation of traditional Chinese medicine syndromes. ConclusionOn the basis of the original model， the animal model of ovarian cancer was added with Qi deficiency syndrome， blood deficiency syndrome， Qi stagnation syndrome， blood stasis syndrome， heat-toxin syndrome， and Yang deficiency syndrome to establish an animal model combining traditional Chinese medicine disease and syndrome of ovarian cancer， which could better simulate the clinical actual situation of traditional Chinese and Western medicine and lay a solid foundation for the study of integrated traditional Chinese and Western medicine for the treatment of ovarian cancer.

¿Es diferente la conectividad estructural en niños y adolescentes familiares de pacientes con trastorno bipolar? Una revisión narrativa según estudios con DTI

Introducción: El trastorno afectivo bipolar (TAB) se ha asociado con una disminución de la integridad de la sustancia blanca. Los estudios con imágenes con tensor de difusión (DTI) han permitido elucidar con una mayor calidad estos cambios. Debido a la gran heredabilidad del TAB, se han realizado estudios en familiares de pacientes con TAB acerca de la integridad de la sustancia blanca, y se ha encontrado que la conectividad estructural también puede estar afectada. Dicha alteración se ha propuesto como un potencial biomarcador de vulnerabilidad a este trastorno. Sin embargo, los estudios en niños y adolescentes son pocos. Objetivo: Revisar la literatura sobre los cambios en la integridad de la sustancia blanca determinados mediante DTI en niños y adolescentes con alto riesgo. Resultados: Se describe la conectividad estructural cerebral en la población pediátrica en estudios que utilizaron DTI. Se describen los cambios en el proceso de mielinización desde su evolución dentro del neurodesarrollo normal hasta los hallazgos en la anisotropía fraccional (AF) en pacientes con TAB y los familiares en alto riesgo. Conclusiones: Los estudios demuestran que tanto pacientes con TAB como sus familiares en riesgo presentan disminución de la AF en regiones cerebrales específicas. Los estudios en niños y adolescentes con riesgo familiar de TAB señalan una AF reducida en tractos axonales implicados en funciones emocionales y cognitivas. La disminución de la AF puede considerarse como un biomarcador de vulnerabilidad al TAB.

Introduction: Bipolar disorder (BD) has been associated with a decrease in white matter integrity. Diffusion tensor imaging (DTI) studies have enabled these changes to be elucidated with higher quality. Due to BD's high heritability, some studies have been conducted in relatives of BD patients looking at white matter integrity, and have found that structural connectivity may also be affected. This alteration has been proposed as a potential BD biomarker of vulnerability. However, there are few studies in children and adolescents. Objective: To conduct a review of the literature on changes in white matter integrity determined by DTI in high-risk children and adolescents. Results: Brain structural connectivity in the paediatric population is described in studies using DTI. Changes in the myelination process from its evolution within normal neurodevelopment to the findings in fractional anisotropy (FA) in BD patients and their high-risk relatives are also described. Conclusions: Studies show that both BD patients and their at-risk relatives present a decrease in FA in specific brain regions. Studies in children and adolescents with a high risk of BD, indicate a reduced FA in axonal tracts involved in emotional and cognitive functions. Decreased FA can be considered as a vulnerability biomarker for BD.

Real-world outcomes and complications of different surgical approaches for significant submacular haemorrhages

Purpose: To evaluate the outcomes and complications after different surgical management of cases with significant sumacular hemorrhage (SMH) of size more than 4 disc diameter (DD). Methods: It was a retrospective interventional study. All consecutive 103 cases of significant SMHs were treated by vitrectomy and divided into three groups. In Group A (<4 weeks, confined to the macula or extending inferiorly, n = 62), vitrectomy, subretinal cocktail of tissue plasminogen activator (tPA), antivascular endothelial growth factor, and air with SF6 gas; in Group B (4–8 weeks, extending beyond macula, n = 31), subretinal tPA followed by SMH drainage either by retinotomy (Group B?1, n = 17) or by temporal 180?degree retinectomy (Group B?2, n = 14) with silicone oil (SO) tamponade; and in Group C (>8 weeks, extending beyond macula, n = 10), SMH removal with autologous retinal pigment epithelium (RPE)?Choroid patch graft transplantations with SO tamponade were performed. Parameters evaluated were best corrected visual acuity (BCVA), Optos, optical computerized tomography, and ultrasonography as required. Results: Significant visual improvement was seen from mean preoperative to mean postoperative BCVA in Group A (P < 0.001), Group B (P < 0.001), and Group C (P < 0.001). Postoperative complications were recurrent SMH (4.84% vs 12.90% vs 10%), vitreous hemorrhage (6.45%, GroupA), hyphema (4.84% vs 12.90% vs 10%), hypotony (nil vs 3.23% vs 20%), macular hole formation (6.45%, Group A), epiretinal membrane (16.13%, Group B), and retinal detachment (3.23%, Group A and 10%, Group C).

This study evaluated selected structural and physical properties, such as degree of conversion (DC), Vickers hardness (VHN), and compression strength (CS), of three new dual-cure bulk-fill resin-based composites (RBCs; ACTIVA, HyperFIL, and Fill-Up) and compared them to those of a conventional RBC (Filtek Z250) at three clinically relevant depths. Samples (n=180) were prepared in three depths (2,4, and 6mm). Fourier-transform infrared spectroscopy (FTIR) analysis and VHN and CS tests were performed. The DC value was calculated by considering the relative change in the aliphatic C=C peaks. The fractured surfaces of representative samples were characterized using scanning electron microscopy (SEM). Data were statistically evaluated using two-way analysis of variance and post hoc Bonferroni tests (p<0.05). According to the VHN results, Filtek Z250 showed the highest bottom/top hardness ratio (97.94±1.01) at 2mm thickness and ACTIVA showed the lowest bottom/top hardness ratio (43.48±5.64) at 6mm thickness (p<0.001). According to the FTIR results, the DC decreased with increasing thickness in all materials (p<0.05). Filtek Z250 showed the highest (301±12.4 MPa) and ACTIVA exhibited the lowest (232±17.2 MPa) CS values at 2mm thickness (p<0.05). The lowest CS values were obtained for ACTIVA, and the highest values were obtained for Filtek Z250 for samples with thicknesses of 4 and 6mm, respectively (p<0.05). The structural features of restorative composites, such as the resin chemistry and filler type and content, and the operational parameters (i.e., material thickness and curing conditions) strongly affect crosslinking reactions and thus the DC, VHN, and CS values.

Este estudio evaluó propiedades físicas y estructurales, como el grado de conversión (DC), la dureza Vickers (VHN) y la resistencia a la compresión (CS), de tres nuevos compósitos a base de resina de curado dual tipo bulk (RBC; ACTIVA , HyperFIL y Fill-Up) y los comparó con los de una resina compuesta convencional (Filtek Z250) en tres profundidades clínicamente relevantes. Se prepararon muestras (n=180) en tres profundidades (2,4 y 6mm). Se realizaron análisis de espectroscopia infrarroja por transformada de Fourier (FTIR) y pruebas VHN y CS. El valor de DC se calculó considerando el cambio relativo en los picos alifáticos C=C. Las superficies fracturadas de muestras representativas se caracterizaron mediante microscopía electrónica de barrido (MEB). Los datos se evaluaron estadísticamente mediante análisis de varianza de dos vías y pruebas post hoc de Bonferroni (p<0,05). De acuerdo con los resultados de VHN, Filtek Z250 mostró la relación de dureza inferior/superior más alta (97,94±1,01) con un espesor de 2mm y ACTIVA mostró la relación de dureza inferior/superior más baja (43,48±5,64) con un espesor de 6mm (p<0,001). De acuerdo con los resultados de FTIR, la DC disminuyó al aumentar el espesor en todos los materiales (p<0,05). Filtek Z250 mostró los valores de CS más altos (301±12,4 MPa) y ACTIVA los más bajos (232±17,2 MPa) a 2mm de espesor (p<0,05). Los valores más bajos de CS se obtuvieron para ACTIVA y los valores más altos para Filtek Z250 para muestras con espesores de 4 y 6mm, respectivamente (p<0,05). Las características estructurales de las resinas compuestas de restauración, como la química; además del tipo y contenido del relleno, y los parámetros operativos (es decir, el espesor del material y las condiciones de curado) afectan en gran medida las reacciones de interacción química y, por lo tanto, los valores de DC, VHN y CS.

Discussion on the establishment of the discipline of "organ donation" / 器官移植

Vivid and abundant social practice constantly creates new understanding, which will inevitably lead to the emergence of new disciplines. Organ donation discipline is involved with multiple disciplines, such as ethics, law, medicine, sociology and psychology, etc. After entering a new stage of high-quality development, whether it is necessary to establish the discipline of "organ donation" is worthy of discussion. According to the basic standards for establishing a new discipline, groundbreaking achievements in organ donation could lay a solid foundation for the establishment of "organ donation" discipline. However, current conditions for the establishment of "organ donation" are not fully mature, and the process of discipline establishment will absolutely encounter resistance. In the future, the scope and orientation of organ donation should be further elucidated, and a series of measures should be taken, such as establishing independent academic organizations, offering organ donation courses, carrying out special research and innovation, and strengthening international cooperation and exchanges, aiming to promote the establishment of organ donation discipline. The cooperation between academic community and governments is the key to promote the establishment of the discipline of organ donation. Governments will make final decisions by comprehensively considering the investment of resources, development needs of the discipline and the relationship among existing disciplines.

Fitting Degrees of Cathartic Colon Animal Models with Disease Characteristics of Western Medicine and Syndrome Characteristics of Traditional Chinese Medicine / 中国实验方剂学杂志

Cathartic colon （CC） is a common and refractory digestive system disease， with the pathogenesis not fully clarified. The effective therapies other than laxatives and surgery remain to be developed for CC. Therefore， establishing the CC animal models that fit the disease characteristics of western medicine and syndrome characteristics of traditional Chinese medicine （TCM） is an important link to promote the research on this disease. The fitting degree of animal models with the latest Chinese and western medical diagnostic criteria is an indicator to assess the effectiveness of the animal models in simulating the disease characteristics of western medicine and syndrome characteristics of TCM. The literature review showed that the model animals， drugs and their dosage forms， doses， administration methods， and modeling period of CC varied in different studies， and the available CC animal models presented different fitting degrees with the disease characteristics of western medicine and syndrome characteristics of TCM. Rats were the preferred animals for the modeling of CC. Rhei Radix et Rhizoma preparations were commonly used for model inducing， which， however， may cause water electrolyte disorders， decreased immunity， and even death of animals at the late stage of modeling. The animals were modeled by gradually increasing the starting dose， while the starting dose and increasing dose varied. The maintenance dose was determined based on 50% of the animals having loose stools， and the end for a cycle was determined as the time when loose stools disappeared in 80% of animals. The modeling always lasted for 2-3 cycles， approximately 2-4 months. The CC models established with Rhei Radix et Rhizoma granules and rhein had high fitting degrees with the disease and syndrome characteristics. In addition， the CC animal models of TCM syndromes were still in the exploration stage. There were only the animal models of four TCM syndromes： liver depression and spleen deficiency， both Qi and Yin deficiency， Qi stagnation and blood stasis， and spleen and kidney deficiency. Efforts should be made to establish the animal models that meet the characteristics of disease of western medicine and syndromes of TCM， so as to facilitate the research on CC mechanism and drug development.

@#Objective    To establish a machine learning model based on computed tomography (CT) radiomics for preoperatively predicting invasive degree of lung ground-glass nodules (GGNs). Methods    We retrospectively analyzed the clinical data of GGNs patients whose solid component less than 3 cm in the Department of Thoracic Surgery of Shanghai Pulmonary Hospital from March 2021 to July 2021 and the First Hospital of Lanzhou University from January 2019 to May 2022. The lesions were divided into pre-invasiveness and invasiveness according to postoperative pathological results, and the patients were randomly divided into a training set and a test set in a ratio of 7∶3. Radiomic features (1 317) were extracted from CT images of each patient, the max-relevance and min-redundancy (mRMR) was used to screen the top 100 features with the most relevant categories, least absolute shrinkage and selection operator (LASSO) was used to select radiomic features, and the support vector machine (SVM) classifier was used to establish the prediction model. We calculated the area under the curve (AUC), sensitivity, specificity, accuracy, negative predictive value, positive predictive value to evaluate the performance of the model, drawing calibration and decision curves of the prediction model to evaluate the accuracy and clinical benefit of the model, analyzed the performance in the training set and subgroups with different nodule diameters, and compared the prediction performance of this model with Mayo and Brock models. Two primary thoracic surgeons were required to evaluate the invasiveness of GGNs to investigate the clinical utility of the mode. Results    A total of 400 patients were divided into the training set (n=280) and the test set (n=120) according to the admission criteria. There were 267 females and 133 males with an ……

Analysis of doctor′s diagnosis and treatment behavior before and after the implementation of diagnosis-intervention packet based on propensity score matching: taking chronic diseases as an example / 中华医院管理杂志

Objective:To analyze the effect of the implementation of diagnosis-intervention packet (DIP) on the doctors′ diagnosis and treatment behavior of chronic diseases, so as to provide reference for further improving medical insurance payment related policies.Methods:The first page information of chronic disease patients admitted to hospitals with diabetes, hypertension and coronary atherosclerotic heart disease as the main conditions in 103 hospitals at all levels and township health centers in a city from 2016 to 2020 was collected, and the patients were divided into non-DIP group and DIP group according to the implementation time of DIP. After 1∶1 propensity score matching to balance the general conditions of the 2 groups, the diagnosis and treatment behaviors were analyzed from two dimensions: diagnostic behavior and treatment behavior. The grade A rate of medical record writing, admission and discharge diagnosis coincidence rate, and the average length of stay were used to evaluate the diagnostic behavior; the proportion of drugs and the degree of change in the cost structure were used as the evaluation indicators of treatment behavior.Results:After matching, 41 050 patients were included in both the non-DIP group and the DIP group.From the perspective of diagnostic behavior, the grade A rate of medical record writing in the non-DIP group and the DIP group was 99.40% and 99.83%, the coincidence rate of admission and discharge diagnosis was 58.42% and 61.79%, the average hospital stay was 8.03 days and 7.04 days respectively, and the difference between the groups was significant ( P<0.05). From the view of treatment behavior, the proportion of drugs decreased from 33.00% in the non-DIP group to 27.59% in the DIP group, with a significant difference ( P<0.05); the drug cost represented by Western medicine changed negatively, while the diagnostic cost showed a positive change. Conclusions:DIP has played a certain role in regulating doctors′ diagnosis and treatment behavior for chronic diseases. Among them, doctors have significantly improved their diagnostic behavior for chronic diseases, and the proportion of drugs in treatment behavior has been well controlled.
