Duodenal malignant melanoma: Primary and metastatic case series and literature review.

Rationale: Duodenal malignant melanoma is rare, and its early clinical symptoms are insidious, making it difficult to diagnose in its early stages. Combined with previous literature, We explored the clinicopathological characteristics and v-raf murine sarcoma viral oncogene homolog B1 mutations in primary and metastatic duodenal malignant melanoma, in order to provide some experience on its differential diagnosis and treatment.

Patient Concerns: The 2 patients (a 63-year-old female [Patient 1] and a 54-year-old male [Patient 2]) experienced pain and discomfort in their upper abdomen.

Protects against Primary Dysmenorrhea in Mice by Inhibiting Inflammatory Response and Regulating the COX2/PGE2 Pathway.

Peony pollen contains multiple nutrients and components and has been used as a traditional Chinese medicine with a long history, but the effect of the treatment of primary dysmenorrhea remains to be clarified. The aim of this study is to investigate the therapeutic effect of peony pollen on primary dysmenorrhea mice and the potential mechanism. A uterus contraction model in vitro and primary dysmenorrhea mice were used to evaluate the treatment effect of peony pollen on primary dysmenorrhea.

Aim Of The Review: The purpose of this review article was to summarize information on the traditional uses, phytochemistry, pharmacology and pharmacokinetics of MC, as well as to outline the further research directions for the development of new drugs and the associations between traditional uses and pharmacological effects.

Lacunes and type 2 diabetes mellitus have a joint effect on cognitive impairment: a retrospective study.

Objective: To evaluate the joint effects of cerebral small vessel disease (CSVD)-related imaging biomarkers in patients of type 2 diabetes mellitus (T2DM) with cognitive impairment.

Methods: This study is a retrospective cohort study. A total of 227 participants (115 patients with T2DM and 112 healthy control subjects) were enrolled in this study.

Altered Structural and Functional MRI Connectivity in Type 2 Diabetes Mellitus Related Cognitive Impairment: A Review.

Type 2 diabetes mellitus (T2DM) is associated with cognitive impairment in many domains. There are several pieces of evidence that changes in neuronal neuropathies and metabolism have been observed in T2DM. Structural and functional MRI shows that abnormal connections and synchronization occur in T2DM brain circuits and related networks.

Anatomic study of carpal tunnel in adults using monoenergetic reconstruction of dual-energy computed tomography.

Objective: To seek optimal keV settings for imaging carpal tunnel in adults by dual-energy computed tomography (DECT) monoenergetic technique; to describe anatomic characteristics of carpal tunnel and to observe correlation between carpal bony and soft tissue structures.

Methods: DECT images of 20 wrists (11 left and 9 right wrists; 14 men, mean age 26.93±1.

Clinical Factors Associated with Progression and Prolonged Viral Shedding in COVID-19 Patients: A Multicenter Study.

Coronavirus disease 2019 (COVID-19) is a global pandemic associated with a high mortality. Our study aimed to determine the clinical risk factors associated with disease progression and prolonged viral shedding in patients with COVID-19. Consecutive 564 hospitalized patients with confirmed COVID-19 between January 17, 2020 and February 28, 2020 were included in this multicenter, retrospective study.

Magnetic Resonance Texture Analysis in Alzheimer's disease.

Texture analysis is an emerging field that allows mathematical detection of changes in MRI signals that are not visible among image pixels. Alzheimer's disease, a progressive neurodegenerative disease, is the most common cause of dementia. Recently, multiple texture analysis studies in patients with Alzheimer's disease have been performed.

A promising structural magnetic resonance imaging assessment in patients with preclinical cognitive decline and diabetes mellitus.

Subjective cognitive decline (SCD) is frequently reported in diabetic patients. Diabetes mellitus (DM) is associated with changes in the microstructure of the brain arise in diabetic patients, including changes in gray matter volume (GMV). However, the underlying mechanisms of changes in GMV in DM patients with cognitive impairment remain uncertain.

A Diagnostic Accuracy Meta-analysis of CT and MRI for the Evaluation of Small Bowel Crohn Disease.

Rationale And Objectives: This study aimed to evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) and computed tomography (CT) in assessing small bowel (SB) Crohn disease (CD).

Materials And Methods: We systematically searched PubMed, Elsevier, ScienceDirect, Karger, Web of Science, Wiley Online Library, and Springer for studies in which CT or MRI were evaluated to assess SB CD. Bivariate random effect meta-analytic methods were used to estimate pooled sensitivity, specificity, and receiver operating characteristic curves.

Cerebral microbleeds, cognitive impairment, and MRI in patients with diabetes mellitus.

Cerebral microbleeds (CMBs), a typical imaging manifestation marker of sporadic cerebral small vessel disease, play a critical role in vascular cognitive impairment, which is often accompanied by diabetes mellitus (DM). Hence, CMBs may, in part, be responsible for the occurrence and development of cognitive impairment in patients with diabetes. Novel magnetic resonance imaging (MRI) sequences, such as susceptibility-weighted imaging and T2*-weighted gradient-echo, have the capability of noninvasively revealing CMBs in the brain.

[Diffusion tensor imaging map of anterior cruciate ligament contrasted with MRI in healthy adults].

Objective: To measure anterior cruciate ligament (ACL) by diffusion tensor imaging (DTI), combined with ACL half quantitative measurement magnetic resonance imaging (MRI) method as the contrast, and to preliminarily investigate the feasibility of DTI for ACL.

Methods: The ACLs of 31 healthy volunteers were scanned with ordinary MRI and DTI. At ordinary MRI map, sagittal ACL-tibial angle, coronal ACL-tibial angle, Blumensaat line-ACL angle, angle of inclination of the intercondylar roof, and ACL-tibial insertion site were measured.

Surgical treatment for rabbits' femoral arteries subjected to gunshot wounds combining with seawater immersion.

Objective: To investigate the surgical treatment methods and evaluate the outcome of gunshot wounds combining with seawater immersion in rabbits' femoral arteries.

Methods: One hundred healthy New Zealand white rabbits (either sex, 3.14 kg+/-0.

Pathological study of rabbits' femoral arteries subjected to gunshot wounds combining with seawater immersion.

Objective: To investigate pathological characteristics of gunshot wounds concomitant seawater immersion in rabbits' femoral arteries.

Methods: Thirty rabbits were divided randomly into 3 groups: simple gunshot-wound group (Group I, n = 10), gunshot wound with seawater immersion for 30 mins (Group II, n = 10), and 60 mins group (Group III, n = 10). Femoral arteries were impacted by 0.

Relevance of NAC-2, an Na+-coupled citrate transporter, to life span, body size and fat content in Caenorhabditis elegans.

We have cloned and functionally characterized an Na+-coupled citrate transporter from Caenorhabditis elegans (ceNAC-2). This transporter shows significant sequence homology to Drosophila Indy and the mammalian Na+-coupled citrate transporter NaCT (now known as NaC2). When heterologously expressed in a mammalian cell line or in Xenopus oocytes, the cloned ceNAC-2 mediates the Na+-coupled transport of various intermediates of the citric acid cycle.

Methods: Defects of the hind limbs of dogs were repaired with skin, muscle and myocutaneous flaps.

Results: Wounds healed within 2 weeks in the experimental group except one that healed in 3 weeks because of infection.
