Objective To observe the effective outcome of application of Ruyi golden powder and magnesium sulfate in the treatment of phlebitis caused by amiodarrone.Methods 60 patients were randomly divided into the observation group and the control group (30 cases in each group).The external application of Ruyi golden powder which was prepared with 75% alcohol into a paste was used in the observation group and 50% magnesium sulphate was used in the control group.Results The total effective rate of two groups of patients was 93.3% in the observation group and 66.7% in the control group,the significant difference was found by the comparison of the two groups.Conclusions The external application of Ruyi golden powder with alcohol in the treatment of phlebitis caused by amiodarrone is better than magnesium sulfate.

Objective To investigate the mechanism and clinical characteristics of rapid spontaneous resolution of acute subdural hematoma in children. Methods The clinical data of 9 children with rapid spontaneous resolution of acute subdural hematoma were retrospective analyzed. Results Subdural hematoma of three cases were completely dissolved within 8 h, while those of the other 6 cases were significantly reduced which were completely dissolved in 48-72 h. Conclusions Rapid spontaneous resolution of acute subdural hematoma in children is rare in clinical practice. The redistribution and dilution of hematoma and the anatomical characteristics of the children patient determine the possibility of hematoma dissipation. The conservative treatment can get a good prognosis.

AIM:To determine the relationship between microhistology and cardiac contractility in myocarditis animal model. METHODS:Setting up myocarditis animal model by injecting Coxsackivevirus B 3 (CVB 3) into mice, then observed myocardial morphological changes and measured left ventricular function of mice at the time of first three days and two weeks after injecting CVB 3.RESULTS:Subcellular structure (mitochondria) changed at the first three days after injecting CVB 3. The left ventricular pressure (LVP) and the rate of intraventricular pressure development (d p /d t ) which is the index of reflecting cardiac contractility depressed in this stage (14.2?0.8) kPa and (273.1?10.0)kPa/s, respectively. There were (17.1?0.7)kPa and (359.8?9.3)kPa/s in normal mice, respectively ( P

Objective:
To explore the related factors of subependymal hemorrhage (SEH) and cerebral hemodynamic changes.
Methods:
From October 2012 to October 2017, 200 cases of children with subependymal hemorrhage diagnosed by ultrasound in our department of pediatrics were selected as the observation group , and a total of 150 children who were admitted to the Department of Pediatrics in the same period due to craniocerebral diseases and other serious diseases were selected as control group. The independent risk factors of the children in the observation group were analyzed, and the difference of the maximum systolic blood flow velocity (SV), the diastolic maximum flow velocity (DV), the systolic and diastolic velocity ratio (S/D), the resistance index (RI), and the pulsatile index (PI) were compared between the two groups.
Results:
Neonatal asphyxia, preterm birth, acidosis, neonatal respiratory distress syndrome (NRDS), patent ductus arteriosus and coagulation dysfunction were independent risk factors for subependymal hemorrhage. The bleeding side SV and DV of the observation group were higher than those of the control group, with statistically significant difference (
