Achalasia and its subtypes: a Moroccan cohort in Ibn Sina Hospital, Rabat

Introduction: achalasia is an esophageal motility disorder, characterized by irregular peristalsis and inadequate relaxation of the lower esophageal sphincter, typically manifests with dysphagia as its primary symptom. The advent of high-resolution manometry (HRM) has transformed our comprehension of achalasia. It has delineated three distinct subtypes based on variations in pressurization and contractions, contributing significantly to the understanding of this condition. This study aimed to describe and compare clinically and manometrically the patients suffering from the different subtypes of achalasia. Methods: it is a retrospective single-center study including all patients with achalasia diagnosed by high-resolution manometry (HRM) between April 2018 and January 2023. The diagnosis was retained based on the latest Chicago 3.0 classification. Results: out of 103 patients, 25.2% (n=26) had type I achalasia, 66.9% (n=69) type II, and 7.8% (n=8) type III. Patients with type I and II achalasia were younger than patients with type III achalasia (mean age 43.2 years vs. 55.6 years, P=0.0053). A female predominance was found in type I achalasia and a male predominance in type III. The most frequent symptoms were: dysphagia (found in all our patients). At HRM, all our patients had a pathological IRP with a mean of 26.95 mmHg for the 3 types of achalasia. Resting IBS pressures were higher in patients with type III achalasia compared to types I and II (35.28 mmHg vs 32.7 mmHg and 31.04 mmHg, P=0.40). Conclusion: achalasia is one of the most studied esophageal motility disorders. Tools such as HRM have permitted us not only to identify achalasia early but also to define different subtypes, which can have therapeutic implications.

ObjectiveThrough the correlation analysis between intestinal absorption profile and inhibition of macrophage foaming， the pharmacodynamic components of Zhuriheng dripping pills（ZRH） were explored to provide a basis for establishing its quality standard. MethodIntestinal absorption fluids with 0， 5， 10， 15， 20 times clinical equivalent doses were prepared by a rat everted gut sac（EGS）， and the oxidized low density lipoprotein（ox-LDL）-induced RAW264.7 macrophage foaming model was used to investigate the effect of intestinal absorption fluid with different doses on the accumulation of lipids in RAW264.7 cells by oil red O staining and cholesterol content determination， and to screen for the optimal dose. Ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS） was used to analyze and identify intestinal absorption fractions of ZRH intestinal absorption fluids， and partial least squares-discriminant analysis（PLS-DA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were performed on different doses of ZRH intestinal absorption fluids using SIMCA 13.0 with peak area as the independent variable and the pharmacodynamic indicators as the dependent variables to screen the compounds with variable importance in the projection（VIP） value>1.0 as contributing components， and Pearson correlation analysis was used to determine the spectral effect relationship， determined the compounds and positive correlation with pharmacodynamic were as active ingredients. Molecular docking was used to verify the binding energy of peroxisome proliferator-activated receptor α（PPARα）， PPARγ， PPARβ， human retinoid X receptor α（RXRA） and nuclear transcription factor-κB（NF-κB） with the active ingredients in ZRH intestinal absorption fluids. Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was performed to detect the mRNA levels of PPARγ， scavenger receptor A1（SRA1） and adenosine triphosphate-binding cassette transporter A1（ABCA1） in RAW264.7 cells， Westen blot was used to detect the expression level of PPARγ protein in RAW264.7 cells， and enzyme-linked immunosorbent assay（ELISA） was used to detect the levels of interleukin（IL）-1β and NF-κB in RAW264.7 cells. ResultAccording to the results of oil red O staining and cholesterol content determination， the ZRH intestinal absorption fluids could significantly reduce macrophage foaming， and intestinal absorption fluids with 15， 20 times clinical equivalent doses had the best effect， the 15-fold ZRH intestinal absorption fluid was finally determined as the study subject. Spectral effect relationship showed that 52 corresponding peaks in the ZRH-containing intestinal fluid were positively correlated with the efficacy， including organic acids， phenylpropanoids， iridoids， flavonoids， bile acids， coumarins and chromones. Target validation results showed that 86.9%-96.2% of the total components processed good binding activities with the key targets of PPARα， PPARγ， PPARβ， RXRA and NF-κB， and the docking energy values were all less than -6.0 kcal·mol-1（1 cal≈4.19 J）. The results of validation showed that， compared with the normal group， the model group showed a significant increase in the levels of SRA1 and PPARγ mRNA expression， a significant decrease in ABCA1 mRNA expression， a significant increase in the level of PPARγ protein expression， and a significant increase in the levels of IL-1β and NF-κB（P<0.01）， compared with the model group， the 15-fold intestinal absorption fluid group showed a significant decrease in the levels of SRA1 and PPARγ mRNA expression（P<0.05， P<0.01）， ABCA1 mRNA expression level was significantly up-regulated， the levels of IL-1β and NF-κB were significantly reduced（P<0.01）， and PPARγ protein expression level was significantly reduced（P<0.05）. ConclusionThis study identifies 52 components and their metabolites in ZRH intestinal absorption fluid that are positively correlated with the inhibition of macrophage foaming， which may be related to the regulation of the PPARs pathway in cells and the reduction of the levels of inflammatory factors， and can provide a reference for the quality control and clinical application of ZRH.

ObjectiveTo investigate the effects of Aconiti Coreani Radix and Typhonii Rhizoma on the urinary metabolites of gerbils with stroke by non-targeted metabolomics technique， and then to clarify the mechanism of the two， as well as their similarities and differences. MethodTwenty-four gerbils were randomly divided into control group（CG）， model group（MG）， Aconiti Coreani Radix group（RA） and Typhonii Rhizoma group（RT）. Except for the CG， ischemic stroke model was constructed using right unilateral ligation of gerbil carotid artery in the remaining groups. Except for the CG and MG， rats in the other groups received whole powder suspension（0.586 mg·g-1） was administered for 14 days. The neurological deficit in each group was scored by Longa scoring on days 0， 3， 7 and 14. After the end of administration， the serum， brain tissue and urine of gerbils in each group were collected， and the rate of cerebral infarction was detected by 2，3，5-triphenyltetrazolium chloride（TTC）， and the levels of interleukin（IL）-6， tumor necrosis factor（TNF）-α， malondialdehyde（MDA）， superoxide dismutase（SOD）， glutathione（GSH）， and nitric oxide（NO） in serum and brain tissue were determined by enzyme-linked immunosorbent assay（ELISA）. The urine metabolomics of gerbils in each group was studied by ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Orbitrap-MS）， and the data were processed by multivariate statistical analysis， and differential metabolites were screened based on value of variable importance in the projection（VIP） of the first principal component>1 and t-test P<0.05. Metabolic pathway analysis of the screened differential metabolites was performed using Kyoto Encyclopedia of Genes and Genomes（KEGG） database and Metaboanalyst 5.0. ResultCompared with the CG， the neurological deficit score was significantly increased in the MG（P<0.05）， compared with the MG， the neurological deficit scores in the RA and RT were significantly reduced after 7 d and 14 d（P<0.05）. Compared with the CG， the rate of cerebral infarction was significantly increased in the MG（P<0.05）， compared with the MG， the rates of cerebral infarction in the RA and RT were significantly reduced（P<0.05）. Compared with the CG， the levels of IL-6， TNF-α， and MDA in the serum and brain tissue of gerbils from the MG were significantly increased（P<0.05）， and the levels of SOD， GSH and NO were significantly reduced（P<0.05）. Compared with the MG， Aconiti Coreani Radix and Typhonii Rhizoma could down-regulate the levels of IL-6， TNF-α and MDA， and up-regulated the levels of SOD， GSH and NO. A total of 112 endogenous differential metabolites were screened by urine metabolomics， of which 16 and 26 metabolites were called back by Aconiti Coreani Radix and Typhonii Rhizoma， and could be used as potential biomarkers for both treatments in stroke gerbils， respectively. The results of the pathway analysis showed that both Aconiti Coreani Radix and Typhonii Rhizoma had regulatory effects on arginine and proline metabolism， pyrimidine metabolism， and aminoacyl-tRNA biosynthesis. In addition， Aconiti Coreani Radix could also regulate riboflavin metabolism， Typhonii Rhizoma could also regulate purine metabolism， glycine， serine and threonine metabolism， arachidonic acid metabolism， biosynthesis of pantothenate and coenzyme A， and β-alanine metabolism. ConclusionBoth Aconiti Coreani Radix and Typhonii Rhizoma have better therapeutic effects on stroke， with Aconiti Coreani Radix having stronger effects. From the metabolomics results， the main metabolic pathways regulated by Aconiti Coreani Radix involve amino acid metabolism， oxidative stress and so on， while Typhonii Rhizoma mainly involve amino acid metabolism， lipid metabolism， energy metabolism， etc.

Cuando negocian los rebeldes colombianos: indicadores estratégicos del acuerdo de paz con las FARC

¿Porque grupos como las FARC firmaron un acuerdo de paz, mientras otros grupos como el ELN se niegan a hacerlo? La respuesta a este interrogante está ligada al concepto de punto de inflexión, que es el momento crucial en el que los acontecimientos giran hacia su resultado final. National Security Research Division (RAND) ha determinado indicadores comunes a los puntos de inflexión de ochenta y nueve conflictos contrainsurgentes, con el fin de promover e identificar la llegada de esta fase final del conflicto. Este trabajo presenta una metodología de análisis cualitativo basada en estos indicadores de debilitamiento de la insurgencia, que sugieren los posibles resultados de los conflictos contrainsurgentes. Estos indicadores se relacionan con la dinámica del conflicto colombiano, lo que permite validar determinadas condiciones estratégicas que posibilitaron la salida negociada al conflicto con las FARC (Fuerzas Armadas Revolucionarias de Colombia). Las conclusiones incluyen ocho indicadores presentes en el curso del conflicto sin los cuales no hubiese sido posible el acuerdo de paz en el resultado tipo II: Gobierno Gana. El estudio propone criterios de evaluación y gestión del conflicto.

Why did groups like FARC sign a peace agreement while other groups like ELN refuse to do so? The answer to this question is linked to the concept of a tipping point, which is the point at which events take a crucial turn toward their outcome. The National Security Research Division (RAND) determined strategic indicators common to tipping points in 89 counterinsurgency conflicts to promote and identify the arrival of this final phase of the conflict. This work presents a qualitative analysis methodology based on these indicators of insurgency weakening that suggest possible outcomes of counterinsurgency conflicts. These indicators are related to information on the dynamics of the Colombian conflict, which allows validation of certain strategic conditions that enabled the negotiated exit from the conflict with FARC. The conclusions include eight indicators present in the course of the conflict without which the peace agreement would not have been possible in the Type II outcome: Government Wins. The study proposes criteria for conflict evaluation and management.

High-Resolution Manometry Contributions to the Physiology of Phonation

High-resolution manometry (HRM) is a motility diagnostic system that measures intraluminal pressure of the gastrointestinal tract using a series of closely spaced pressure sensors. The topographic plot generated by HRM software makes it possible to visualize phonation pressures at the pharynx, UES, and body of the esophagus in real time, indicating pressure intensity by color, which permits easy data interpretation. It has been largely used for swallowing study and dysphagia diagnosis. Due to the proximity of the pharyngoesophageal and laryngeal structures, this technology instigated voice researchers. Despite the few studies published so far, high-resolution manometry has yet proven to be an extremely useful tool in obtaining entire pharyngoesophageal segment pressure measurements during phonation. It also allows natural voice production not interfering with the mouth area. HRM data already brought light to subglottic pressure, vertical laryngeal excursion, cricopharyngeal muscle activation, air flow, muscle tension associated with vocalization and pressure variations associated with different phonatory stimuli.

La manometría de alta resolución (HRM, por sus siglas en inglés) es un sistema de diagnóstico de motilidad que mide la presión intraluminal del tracto gastrointestinal mediante una serie de sensores de presión dispuestos de manera cercana. El gráfico topográfico generado por el software de HRM permite visualizar las presiones de fonación en la faringe, el EEI y el cuerpo del esófago en tiempo real, indicando la intensidad de la presión mediante colores que facilitan la interpretación de los datos. Ha sido ampliamente utilizado para el estudio de la deglución y el diagnóstico de la disfagia. Debido a la proximidad de las estructuras faringoesofágicas y laríngeas, esta tecnología ha despertado el interés de los investigadores en voz. A pesar de los pocos estudios publicados hasta ahora, la manometría de alta resolución ha demostrado ser una herramienta extremadamente útil para obtener mediciones de presión de todo el segmento faringoesofágico durante la fonación. Además, permite la producción natural de la voz sin interferir en el área de la boca. Los datos de HRM ya han arrojado luz sobre la presión subglótica, la excursión laríngea vertical, la activación del músculo cricofaríngeo, el flujo de aire, la tensión muscular asociada con la vocalización y las variaciones de presión asociadas con diferentes estímulos fonatorios.

Using High-Resolution Anoscopy to Detect Anal Dysplasia Due to Papillomavirus in Patients with Inflammatory Bowel Disease

Introduction: Anal squamous cell carcinoma is rare, but its incidence and mortality have been increasing globally; 90% of cases are related to human papillomavirus (HPV) infection(1,2). Patients with inflammatory bowel disease (IBD) have a higher risk of infection with this virus; an incidence of 5.5 per 100,000 patients has been identified in the IBD group compared to 1.8 in the non-IBD group(3). Materials and methods: A descriptive case series study was conducted with 21 patients with IBD and no perianal symptoms between January and July 2022 at the Institute of Coloproctology in Medellín. They underwent anal cytology, HPV genotyping, and high-resolution anoscopy after explanation and acceptance of the procedure. If lesions were found, ablative treatment was performed. Results: 23% of this cohort had low-grade squamous lesions, while 14.2% had high-grade lesions with dysplasia changes during anoscopy. Besides, 90.4% had positive HPV genotyping, of which 76.1% were high-grade. Conclusions: Our study suggests that this series of patients with IBD behaves as a high-risk group for developing premalignant lesions in association with HPV. High-resolution anoscopy is a cost-effective, painless, and affordable method that, in expert hands, may impact the diagnosis and management of premalignant lesions and decrease the incidence of anal cancer in patients with IBD.

Introducción: El carcinoma anal de células escamosas es raro, pero su incidencia y mortalidad han ido en aumento globalmente. El 90% de los casos están relacionados con la infección por el virus del papiloma humano (VPH)1,2 y los pacientes con enfermedad inflamatoria intestinal (EII) tienen un mayor riesgo de infección por este virus; se ha identificado una incidencia de 5,5 por 100.000 pacientes en el grupo de EII frente a 1,8 en el grupo sin EII3. Metodología: Se realizó un estudio descriptivo de serie de casos en el que se incluyó a 21 pacientes con EII, sin síntomas perianales, entre enero y julio de 2022 en el Instituto de Coloproctología de Medellín, a quienes se les realizó citología anal, genotipificación del VPH y anoscopia de alta resolución, previa explicación y aceptación del procedimiento. Si se encontraban lesiones, se realizaba tratamiento ablativo. Resultados: El 23% de esta cohorte tenía lesiones escamosas de bajo grado, mientras que el 14,2% presentaba lesiones de alto grado con cambios de displasia al momento de la anoscopia. El 90,4% tenían genotipificación positiva para VPH, de los cuales el 76,1% eran de alto grado. Conclusiones: Nuestro estudio sugiere que esta serie de pacientes con EII se comporta como un grupo de alto riesgo para desarrollar lesiones premalignas en asociación con el VPH. La anoscopia de alta resolución es un método rentable, indoloro y asequible que, en manos expertas, puede impactar el diagnóstico y manejo de lesiones premalignas y disminuir la incidencia de cáncer anal en pacientes con EII.

La visión de paz del Episcopado colombiano en los gobiernos Uribe (2002-2010)

Este artículo revisó la visión de paz del Episcopado colombiano en los gobiernos de Álvaro Uribe (2002-2010). La constante participación de los prelados en los procesos de paz ha escapado de la atención de la investigación académica, y no ha tenido en su visión de la paz su foco de interés. Este artículo, desde el paradigma hermenéutico-crítico, y el método de Análisis Crítico del Discurso, concluye que dicha participación ha estado marcada por su postura a favor de la paz positiva, que no solo establece la ausencia de guerra y violencia directa, sino también la presencia de la justicia social.

This article reviewed the Colombian Episcopate's vision of peace under Alvaro Uribe's Governments (2002-2010). The constant participation of the prelates in peace processes has escaped the attention of academic research, and their vi sion of peace has not been their focus of interest. This article, from the hermeneutic-critical paradigm, and the method of Critical Discourse Analysis, concludes that such participation has been marked by their stance in favor of positive peace, which not only establishes the absence of war and direct violence, but also the presence of social justice.

Characterization of Achalasia Subtypes Based on High-Resolution Manometry in Patients at a Reference Hospital in Colombia

Introduction: Limited information is available regarding the clinical and manometric characteristics of different subtypes of achalasia. This study aims to describe these characteristics in patients treated at a prominent hospital in Colombia. Methods: This descriptive observational study included patients diagnosed with achalasia using high-resolution esophageal manometry at Hospital Universitario San Ignacio in Bogotá, Colombia, between 2016 and 2020. We documented the clinical manifestations, manometric findings, treatment approaches, and response to treatment based on the subtype of achalasia. Results: A total of 87 patients were enrolled, with a median age of 51 years, and 56.4% of them were female. The majority had type II achalasia (78.1%), followed by type I (16%) and type III (5.7%). All patients presented with dysphagia, 40.2% experienced chest pain, and 27.6% had gastroesophageal reflux. The clinical parameters, including integrated relaxation pressure value (IRP; median: 24 mmHg, interquartile range [IQR]: 19-33), upper esophageal sphincter pressure (UES; median: 63 mmHg, IQR: 46-98), and lower esophageal sphincter pressure (LES; median: 34 mm Hg, IQR: 26-45), were similar across the different subtypes. Esophageal clearance was incomplete in all patients. Among the 35 patients who received intervention, Heller's myotomy was the most commonly employed procedure (68.5%), followed by esophageal dilation (28.6%). All patients experienced symptomatic improvement, with a median pre-treatment Eckardt score of 5 (IQR: 5-6) and a post-treatment score of 1 (IQR: 1-2). Conclusions: Type II achalasia is the most prevalent subtype. The clinical and manometric findings, as well as treatment response, exhibit similarities among the different subtypes of achalasia. In Colombia, the outcomes of this condition align with those reported in other parts of the world.

Resultados: se incluyeron a 87 pacientes (mediana de edad: 51 años, 56,4% mujeres). La mayoría de tipo II (78,1%), seguido por tipo I (16%) y tipo III (5,7%). Todos presentaron disfagia, 40,2% dolor torácico y 27,6% reflujo gastroesofágico. La clínica y los valores del integral de presión de relajación (IRP; mediana: 24 mm Hg, rango intercuartílico [RIC]: 19-33), presión del esfínter esofágico superior (EES; mediana: 63 mm Hg, RIC: 46-98) y presión del esfínter esofágico inferior (EEI; mediana: 34 mm Hg, RIC: 26-45) fueron similares en los diferentes subtipos. El aclaramiento esofágico fue incompleto en todos los pacientes. Entre 35 pacientes que recibieron manejo intervencionista, la miotomía de Heller fue la intervención más utilizada (68,5%), seguido por la dilatación esofágica (28,6%). La totalidad de estos pacientes presentó una mejoría sintomática con la mediana de Eckardt pretratamiento de 5 (RIC: 5-6) y postratamiento de 1 (RIC: 1-2). Conclusiones: la acalasia tipo II es la más común. La clínica y los hallazgos manométricos y respuesta a tratamiento son similares entre los subtipos de acalasia. En Colombia, esta entidad se comporta de forma similar a lo reportado en otras partes del mundo.

Influence of Congenital Heart Defect Types over Cardiopulmonary Bypass, Aortic Cross-Clamping, and Intensive Care Unit Length of Stay and Their Association with Genetic Factors

Aim: Surgical correction of congenital heart defects (CHD) often requires interruption of blood flow through cardiopulmonary bypass (CPB) and aortic cross-clamping (ACC), for which duration(s) are considered to be prognostic factors, along with intensive care unit (ICU) length of stay (ICULOS). The aim of this study was to evaluate these surgical prognostic factors in pediatric patients with different types of CHD regarding their type of lesion and associated genetic factors. Study Design: Cross-sectional cohort study with 307 pediatric patients. Place and Duration of Study: Pediatric Intensive Care Unit (ICU) of Hospital da Criança Santo Antônio, in Porto Alegre/RS, Brazil, from 2006-2009 (3 years) Methodology: After inclusion criteria, we studied 266 pediatric patients admitted for the first time in a reference cardiac pediatric ICU from Southern Brazil following cardiac surgery. Intraoperative prognostic factors such as duration of CPB, ACC and ICULOS, in addition to dysmorphological and cytogenetic examinations were compiled and analyzed. P-values of <0.05 were considered significant. Results: CPB time was associated to four outflow tract defects (Tetralogy of Fallot [ToF], transposition of the great arteries [TGA], double outlet right ventricle, and truncus arteriosus [TA]), atrioventricular septal defect, and hypoplastic left heart syndrome (HLHS) (P < 0.001). ACC duration was associated with three outflow tract defects (ToF, TGA, and TA) and HLHS (P < 0.001). Moreover, CPB and ACC times showed an association with cyanotic and complex heart defects, as well as prolonged ICULOS (P < 0.001). There was no relationship between these prognostic factors and syndromic aspects or cytogenetic findings. Conclusions: CHD type has an impact over CPB and ACC duration and ICULOS, whereas genetic factors are not associated with those prognostic factors.

Empatía y disposición a la reconciliación socioemocional en adolescentes penalizados

(analítico) Este estudio analiza la relación entre la empatía y la disposición a la reconciliación socioemocional en adolescentes infractores de la ley. Con un diseño no experimental, correlacional-predictivo, participaron 171 jóvenes entre 15 y 23 años, judicializados con medida privativa de la libertad en Colombia, 81.1% (n = 137) hombres y 19.9 % (n = 34) mujeres. Se utilizó el índice de reactividad interpersonal y la escala de reconciliación socioemocional. Se hallaron correlaciones positivas (p < 0.05) entre la empatía y la reconciliación socioemocional. El análisis de regresión mostró que la empatía tiene efecto predictor positivo (p < 0.001) sobre la reconciliación socioemocional total (R2=0.154), intrapersonal (R2 = 0.081) e interpersonal (R2 = 0.185). Se concluye que la empatía incide en los procesos de reconciliación socioemocional de los adolescentes judicializados.

Clinical Value Evaluation of DR Corneal Suture Ring Localization and CT 3D Reconstruction Localization of Orbital Foreign Body / 中山大学学报(医学科学版)

ObjectiveTo investigate the clinical value of DR corneal suture ring localization and CT 3D reconstruction localization of orbital foreign bodies. MethodsRetrospective analysis was performed on patients （51 cases） suspected of ocular foreign bodies admitted to our hospital from January 2016 to December 2020 At the same time， DR corneal suture ring localization and CT three-dimensional reconstruction localization of orbital foreign bodies were performed， and the detection rate of foreign bodies by the two methods was calculated to analyze the location of ocular foreign bodies. ResultsThere were 38 cases of intraorbital foreign body identified by DR corneal suture ring localization method， and 46 cases of intraorbital foreign body identified by CT three-dimensional reconstruction localization method. The accuracy of CT three-dimensional reconstruction localization method was 90.20%， which was higher than that of DR corneal suture ring localization method 74.51% （P<0.05）. Intraocular foreign bodies in 23 cases could be distinguished by DR corneal suture ring localization， and 25 cases by CT 3D reconstruction localization. The maximum diameter of intraocular foreign bodies that could be distinguished by CT 3D reconstruction localization was （2.65±0.14） mm. The diameter of intraspherical foreign body was （2.94±0.36） mm （P<0.05） lower than that which could be distinguished by DR corneal suture ring localization method. The results of DR corneal suture ring localization of orbital foreign body showed no difference compared with the results of CT 3D reconstruction localization （P>0.05）. Forty cases of high density images inside and outside the eye could be clearly distinguished by CT 3D reconstruction. By using DR corneal suture ring localization method， 23 cases were confirmed to be intraocular high-density shadows， and 15 cases could not be confirmed to be intraocular high-density shadows （P < 0.05）. ConclusionsFor the location of intraorbital foreign bodies， CT three-dimensional reconstruction can be used as a conventional method for locating ocular foreign bodies with high resolution and accuracy， and can detect fine metal particles inside the eyeball. Meanwhile， for a few small foreign bodies in the iris root， ciliary body and lateral suspension ligament， it is necessary to locate orbital foreign bodies with DR corneal suture ring.
