Objective To find a convenient, fast, accurate, and cost-saving method for the puncture procedure of intracranial hematoma. Method One hundred patients with intracranial hematoma were selected for puncture treatment. According to the midline position of the CT film, mark the projection positions of the hematoma center on the horizontal plane, coronal plane, and sagittal plane of the body surface respectively. One of the marking points can be used as a puncture point, and the plane of the other two targets can be used as the maximum level and puncture angle of the hematoma, which is called the “one point two planes” method. Results After the puncture procedure, using the “one point two planes” method for positioning. The puncture points were in the hematoma center verified by CD film in the 100 patients. Conclusion The “one point two planes” method is convenient, fast, accurate, and cost-saving method for the puncture procedure of intracranial hematoma and is suitable for basic-level hospitals to treat patients with acute cerebral hemorrhage.

Objective: To investigate th regulatory effects of sericin on liver insulin receptor (IR) in type 2 diabetic rats. Methods: Thirty-six SPF male rats were randomly divided into three groups (normal group, model group and experimental group), with 12 rats in each group. The rat model of type 2 diabetes mellitus was induced by high-fat, high-sugar feeding and intraperitoneal injection of streptozotocin. After modeling, the rats were given sericin by gavaging for 35 days in the experimental group. The glucose oxidase method was used to detect the fasting blood glucose of rats in each group. Real Time Q-PCR was used to detect the expression of IR mRNA in liver. Results: Compared with the rats in model group, the blood glucose of rats in experimental group was significantly reduced, and the expression of liver IR of rats in experimental group increased significantly (P< 0.05). Conclusions: Sericin may enhance the transduction effects of insulin signal by up regulating the expression of IR in liver of diabetes mellitus rats, thus reducing the blood glucose.
