Objective To study the clinical features and nursing strategy of rhinocerebral mucormycosis , and to improve the knowledge of the disease and the quality of care .Methods The data of 8 cases with rhinocerebral mucormycosis were reviewed and analyzed .The clinical features and nursing intervention were analyzed throughout the course of disease .Results The underlying immunosuppressive condition of the 8 cases of mucormycosis had diabetes , diabetic ketoacidosis , anaemia or adiotherapy with headache and orbitial apex syndrome as the early symptoms .Nurses focused on local signs observation , perioperative change of intracranial pressure and general conditions , drug adverse reaction observation and nursing care of original disease , mental care, and basic nursing care .There were certain effects for corresponding nursing measures without occurrence of nursing events duration of hospital stay .1 patient died within one week in hospital;4 patients had survived from 3 to 12 months; and 3 patients had been alive over 3 years until now.Conclusions Rhinocerebral mucormycosis was the secondary onset severe diseases for patients with poor immunologic function , implicated in the orbit and brain , and the fatality rate was high .It could hold the development of the disease by clearing up the focus and wiping off the condition of fungi thrive together with medical management and adequacy nursing intervention .

Objective To investigate the application of new portable vein visualizer in venous indwelling needle puncture in children.Methods A total of 432 children from January 2016 to June 2016 in pediatric department were randomly divided into observation group (n=224) and control group (n=208). Children in observation group received self-designed new portable vein visualizer in superficial venous indwelling needle puncture, while children in control group received traditional needle puncture. The one-time puncture success rate, puncture time, pain in children and family satisfaction were compared between two groups.Results The success rate of observation group (95.1%) was significantly higher than control group (73.1%) (χ2=39.881, P<0.05). The puncture time of observation group was shorter (3.400±0.615) than control group (4.850±0.873), with statistically significant difference (t=9.608,P<0.05). The family satisfaction in observation group (96.1%) was significantly higher than control group (85.2%) (χ2=7.037,P<0.05).Conclusions Application of new portable vein visualizer in superficial venous indwelling needle puncture in children improves the success rate, decreases the puncture time, reduces the pain of children and improves family satisfaction.

ObjectiveTo clarify the scientific validity of in vivo pharmacokinetic determination of the whole drug composition in Shenbai nanosuspension in rats， and to provide methodological guidance and theoretical basis for the in vivo study of multi-component complex system of traditional Chinese medicine（TCM） preparations. MethodThe concentration of the overall components， mainly total saponins and total polysaccharides in Shenbai decoction and Shenbai nanosuspension， was determined in rat plasma at different times by area under the absorbance-wavelength curve method（AUAWC）， and the concentration of individual ginsenoside Rg₁ was determined by high performance liquid chromatography（HPLC）， and the methodology was verified. The pharmacokinetic parameters of the whole component were compared with those of ginsenoside Rg₁ to evaluate the in vivo operational characteristics of the two preparations. ResultThe methodological investigations of AUAWC and HPLC were in accordance with the requirements. AUAWC analysis showed that the overall components in both the decoction group and the nanosuspension group showed a one-compartment model， with half-life（t_1/2） of 2.43 h and 2.04 h， respectively. The relative bioavailability of Shenbai nanosuspension was 138.99%. HPLC assay showed that ginsenoside Rg₁ in the decoction group and the nanosuspension group showed a two-compartment model， with distribution half-life（t_1/2α） of 0.13 h and 2.55 h， and elimination half-life（t_1/2β） were 14.28 h and 3.85 h， respectively. The relative bioavailability of Shenbai nanosuspension was 127.49%. Compared with Shenbai decoction， the time to peak（t_max）， peak concentration（C_max） and area under the drug-time curve（AUC） of the overall components and ginsenoside Rg₁ in Shenbai nanosuspension were increased. ConclusionThe established AUAWC can be used for the pharmacokinetic study of the overall components of TCM preparations， which is complementary to the results of individual components measured by HPLC， and can provide useful reference for the in vivo study of new dosage forms of TCM.

The p21 activated kinase 4 (PAK4) is serine/threonine protein kinase that is critical for cancer progression. Guided by X-ray crystallography and structure-based optimization, we report a novel subseries of C-3-substituted 6-ethynyl-1H-indole derivatives that display high potential and specificity towards group II PAKs. Among these inhibitors, compound 55 exhibited excellent inhibitory activity and kinase selectivity, displayed superior anti-migratory and anti-invasive properties against the lung cancer cell line A549 and the melanoma cell line B16. Compound 55 exhibited potent in vivo antitumor metastatic efficacy, with over 80% and 90% inhibition of lung metastasis in A549 or B16-BL6 lung metastasis models, respectively. Further mechanistic studies demonstrated that compound 55 mitigated TGF-β1-induced epithelial-mesenchymal transition (EMT).
