By anti-skid gasket, silica gel soft pad and cross insertion rod structure, it is ensured that support is stable and convenient to store and transport. It can be fine-tuned according to the arm shape of different patients, provide accurate ultrasonic probe positioning, improve the success rate of venous blood sampling and patient comfort. The present application is widely applicable to blood sampling and other diagnosis and treatment operations under medical image guidance, and has good market prospect and practical application value.

The invention provides a method for evaluating the health of sows in the perinatal period based on metagenome sequences, a synthetic microbial community and application, and relates to the technical field of animal nutrition and biologication.The method comprises the steps of sample collection, index detection and judgment, microbial correlation analysis, screening platform construction and nutrient screening. According to the method, the problems that traditional diagnosis depends on highly invasive vein blood sampling and feedback lags behind are solved by excavating the relation between pregnant sow excrement microorganisms and serum insulin resistance and inflammatory factors. And early and accurate early warning of the metabolism health state of the sow can be realized by using fecal microorganisms. The constructed SynCom synthetic flora is not a general formula, but is a metabolic synergistic bacterium which is accurately locked based on big data and has the abundance significantly reduced in the perinatal period. Through directional supplement of the deleted members, excessive expansion of proinflammatory flora such as Prevotelasp.and the like can be effectively antagonized, and insulin resistance induced by inflammation is relieved from the source.

FIELD: surgery.SUBSTANCE: used to predict the effectiveness of treatment of acute pancreatitis in the early stages. On the 1st, 4th, 7th and 11th days after hospitalization, venous blood sampling is performed from patients, the level of C-reactive protein, the activity of phospholipase A2 and alpha-amylase in the blood is assessed, and an ultrasound of the abdominal cavity is performed to identify fluid formation in the abdominal cavity. In patients with acute pancreatitis, the probability of developing complications IRO is calculated using the stated formula. With the IRO value less than 3.1 predicts high treatment effectiveness, indicating the absence of the likelihood of complications. With an IRO value from 3.2 to 4.5, average treatment effectiveness is predicted, indicating possible disease progression and development of complications and the need for constant monitoring. If the IRO value is more than 4.5, the treatment is predicted to be ineffective, indicating a high probability of complications and requiring urgent puncture interventions at the site and adjustments to treatment regimens.EFFECT: method provides the possibility of increasing the accuracy of assessing the treatment of acute pancreatitis in the early stages, predicting the course of acute pancreatitis and optimizing treatment by preventing the risk of fluid formations, due to the assessment of the state of the components of the homeostasis system: pancreatogenic, immunoinflammatory, membrane-destabilizing, and visual diagnostics of the abdominal cavity to identify fluid formations in it.1 cl, 4 tbl, 3 ex
