ObjectiveTo explore the causes and countermeasures for extravasation of intravenous fluids in children. Methods726 cases of intravenous infusion in pediatric surgery department from May to December 2011 in our hospital were observed. ResultsThere were 30 cases with extravasation of intravenous infusion in the 726 cases,the leakage rate was 4.13%.The specific causes of fluid extravasation included:younger age of children,not cooperating with the infusion in 18 cases,accounting for 60.00%,followed by non standardized fixation methods in 5 cases,accounting for 16.67%,and accompanying family members refused to be disturbed accounted for 13.33%,Nursing visits to owe in a timely manner accounted for 6.67%.The rate of younger age of children and lack of cooperation leading to fluid extravasation were significantly higher than other causes,the difference was statistically significant. ConclusionsChildren age,fixation method,cooperation of family members,inspections and other factors can be controlled.Along with the continuous improvement of medical standards and a variety of active and effective implementation of the measures,these factors can be controlled effectively.Strengthening the training of nurses and vocational skills to enhance their own sense of responsibility,to give standardized infusion operation and fixation,and give predictable observation and treatment,can effectively prevent the occurrence of extravasation of intravenous fluids.

Rotundine (1 micromol L(-1)) was incubated with a panel of rCYP enzymes (1A2, 2C9, 2C19, 2D6 and 3A4) in vitro. The remained parent drug in incubates was quantitatively analyzed by an Agilent LC-MS. CYP2C19, 3A4 and 2D6 were identified to be the isoenzymes involved in the metabolism of rotundine. The individual contributions of CYP2C19, 3A4 and 2D6 to the rotundine metabolism were assessed using the method of total normalized rate to be 31.46%, 60.37% and 8.17%, respectively. The metabolites of rotundine in incubates were screened with ESI-MS at selected ion mode, and were further identified using MS2 spectra and precise molecular mass obtained from an Agilent LC/Q-TOF-MSMS, as well as MS(n) spectra of LC-iTrap-MS(n). The predominant metabolic pathway of rotundine in rCYP incubates was O-demethylation. A total 5 metabolites were identified including 4 isomerides of mono demethylated rotundine and one di-demethylated metabolite. The results also showed that CYP2C19, 2D6 and 3A4 mediated O-demethylation of methoxyl groups at different positions of rotundine. Furthermore, the ESI-MS cleavage patterns of rotundine and its metabolites were explored by using LC/Q-TOF-MSMS and LC/iTrap-MS(n) techniques.

Objective To investigate the change of plasma marinobufagenin (MBG) level and the expression of its receptor Na+-K+-ATPase (NKA) in renal biopsy specimens of chronic glomerulonephritis (CGN) patients. Methods Twenty-eight CGN patients and 14 healthy people were enrolled in the study. The plasma MBG concentration was measured by competitive inhibition ELISA system. Immunofluorescence and immunohistochemistry staining were applied to detect the expression of NKA in renal biopsy specimens of 28 CGN patients and analyzed by semi quantitively. Results Compared with healthy controls, CGN patients had significant lower plasma MBG concentration [(0.579±0.214) nmol/L vs (0.715±0.154) nmol/L, P<0.05], without further significant difference between CGN patients with hypertension and with normal blood pressure [(0.595±0.231) nmol/L vs (0.557±0.197) nmol/L, P>0.05]. Meanwhile, proximal tubular staining of NKA was decreased compared with normal controls. The NKA positive staining area of the CGN group was lower than that of normal controls [2.1% (0.5%-6.2%) vs 5.6% (3.5%-10.8%), P<0.01] and correlated with 24-hour urinary sodium excretion (r=0.551, P<0.01).Conclusion Decreased plasma MBG level and its receptor expression on proximal tubules may play a role in the regulation of sodium in CGN.
