0.05). This study suggest that unlike other autonomic ganglia, the enteric nerve ganglia may exhibit a relatively high capacity of autonomic regulation and compensatory adaptation, and also provide some histochemical evidences for the transneuronal degeneration changes.

Objective To investigate the effects of propofol on nitric oxide (NO), superoxide dismutase (SOD) and malondialdehyde (MDA) levels in blood and lung during endotoxic shock in rats.Methods Seventy-two male Wistar rats weighing 180-220 g were randomly divided into thiee groups :group Ⅰ control (C) ( n = 8) ; group Ⅱ endotoxic shock (L) ( n = 32) and group Ⅲ propofol + endotoxic shock (P) ( n = 32) . The animals were anesthetized with 3% pentobarbital 25 mg?kg-1 , tracheostomized and mechanically ventilated . Carotid and pulmonary artery were cannulated for MAP and MPAP monitoring. In group Ⅱ (L) and Ⅲ (P) endotoxin 10 mg?kg-1 was injected intraperitoneally. In group P 10 min before endotoxin administration subcutaneous propofol infusion was started at a rate of 20 mg?kg-1?h-1 . In control group normal saline(NS) was given ip instead of endotoxin. Venous blood samples were taken at 30, 90, 180 and 360 min after intraperitoneal endotoxin or NS injection. In group L and P 8 animals were killed at each time point respectively and in control group the 8 animals were killed at 360 min after ip NS injection. The lungs were immediately removed. Blood and lung NO and MDA levels and RBC SOD content were measured.Results The serum and lung NO concentration measured at all 4 time points were significantly lower in group Ⅲ than those in group n (P

Diffuse choroidal retinal atrophy (DCA) is a type of myopic macular disease that presents with yellowish-white atrophic changes at the posterior pole of the eyeball. DCA is an important critical feature in the diagnosis of pathological myopia. Early intervention and treatment of this disease are of great significance in delaying the progression of pathological myopia and reducing the impairment of visual function. Ophthalmic imaging data can be used to diagnose the disease, and color fundus photography is the most simple and intuitive. Choroidal thickness is also a key indicator in the diagnosis of DCA, but the diagnostic critical value of choroidal thickness has not been clearly defined. With the development and popularization of artificial intelligence technology, the analysis of lesion imaging data is more objective and accurate. In the future, it is expected to actively establish a standard quantitative evaluation system for DCA by means of artificial intelligence to achieve early detection, early diagnosis and early treatment of pathological myopia.
