Abstract The basic signs and symptoms of inflammation and wound healing have been appreciated for thousands of years. However, the specific cells involved and their roles in this complex environment are still being elucidated today. In 1926, the origin of the phagocytic mononuclear ameboid wandering cell (macrophage) had not been determined. One popular theory was that the cells were differentiated from the endothelial cells of the nearby blood vessels, whereas others believed that the cells came from the peripheral blood or resting wandering cells. The purpose of this article is to review the seminal article published by Lang regarding this topic nearly 75 years ago. In addition, this article will review what is now known with regard to the role of the macrophage and endothelial cells in the development of angiogenesis, which is arguably the most critical component of successful inflammatory process or wound healing.

Subclinical Diabetes

BACKGROUND Background: At present, the incidence of diabetes is on the rise. When doctors diagnose and treat patients' diseases, they often need to image patients to provide complementary information on patient anatomy and functional metabolism. OBJECTIVE Objective: The aim was to understand the morphological features of peripheral blood vessels of diabetes more accurately and explore its Risk factors for the occurrence of lesions for early diagnosis and early prevention. METHODS Methods: The paper selected subclinical diabetes patients admitted to our hospital from October 2013 to October 2018 as a research object. After performing colour Doppler ultrasonography on peripheral blood vessels, images of ultrasound images were taken. Then the paper proposes a multi-mode medical image registration method based on hybrid optimization algorithm for the multi-extreme problem of mutual information function. Mutual information is used as the similarity measure. The hybrid optimization algorithm is used to search for the best registration exchange parameters. The quasi-colour super images are exchanged for registration purposes. RESULTS Results: The experimental results show that the hybrid optimization algorithm can accurately analyse the colour ultrasound image of the peripheral blood vessels of subclinical diabetes, avoiding falling into the local optimal value, and the accuracy of the registration result reaches the sub-pixel level. CONCLUSIONS Conclusion: With the rapid development of imaging technology, the increasing image resolution, and the increasing amount of image data, parallel performance is high. The quasi-method has a very important significance for multi-modal medical image registration. The parameters in this algorithm can be further optimized. CLINICALTRIAL

Focal Stenosis

Hemodynamic aspects of obliterative processes in peripheral blood vessels were studied on a mechanical model built of distensible tubing, with a fixed peripheral resistance, through which citrated blood was circulated by pulsatile flow. Hemodynamics of progressive focal stenosis, elongated soft stenosis, and elongated rigid stenosis were assessed. By the use of a hydrodynamic model and a series of in vitro experiments, we have measured the pressure and flow characteristics, and calculated the pressure and energy losses for the various stenotic sites. The critical stricture was found to be larger for a rigid stenosis than a soft stenosis. The length of the stenosis was also an important factor. Increasing the length of a rigid stenosis, for example, by 50 percent resulted in an increase of 25 percent in the flow through the stenosis. The energy dissipation was determined as a preferred indication for several parameters such as: pressure drop, pulsed flow, pulse rate, and the geometry and mechanical properties of the stenosis.

Sarcocystis Tenella

Thirty-seven sheep were inoculated orally with 104 to 66 × 106Sarcocystis tenella sporocysts from dogs or coyotes and necropsied between 1 and 276 days postinoculation (DPI). Two single zoites were found in submucosal arteries of small intestines of lambs 3 and 6 DPI. At 9 to 21 DPI, numerous first-generation meronts were found in mesenteric arteries, intestinal blood vessels, and occasionally in other organs. First-generation meronts were 37.0 × 27.3 μm in sections and 54.4 × 46.6 μm in smears. At 16 to 40 DPI, second-generation meronts were found in capillaries of several organs; renal meronts were 20.6 × 12.0 μm in sections. Merozoites were found in peripheral blood at 14 to 16 DPI and at 25 to 32 DPI. Earliest sarcocysts were found at 35 DPI and contained one to three metrocytes. At 40 DPI, sarcocysts were up to 97 × 10 μm and contained 1 to 13 metrocytes. Bradyzoites formed between 52 and 66 DPI. At 75 DPI, sarcocysts had cross-striated walls and were infective for coyotes. Dogs and coyotes fed infected meat shed sporocysts in feces 9 to 10 days later. Gamonts were found in the small intestine between 8 and 21 h postinoculation and sporulation was completed within 8 days.
