Objective It has been known that hepatopulmonary syndrome(HPS) is related to the imbalance between vasoconstrictors and vasodilators. The aim of the study is to examine the levels of plasma calcitonin gene related peptide (CGRP) and endothelin(ET) in patients with HPS for exploring their roles in HPS formation. Methods The levels of CGRP and ET were measured by radioimmunoassay in 16 cases of HPS, 30 cases of liver cirrhosis without HPS and 15 normal controls. Results The levels of plasma CGRP ((65?15)pg/ml) and ET((78?21)pg/ml) in 16 cases of HPS were significantly higher than those in liver cirrhosis (CGRP (51?15) pg/ml, ET (60?14) pg/ml) and in healthy controls (CGRP (32?12) pg/ml, ET (36?11) pg/ml) ( P 0.05). Conclusions The increase of plasma CGRP and ET is closely associated with the intrapulmonar vascular dilation of HPS and hypoxemia. The levels of plasma CGRP and ET in liver cirrhosis were significantly higher than those in healthy controls ( P

Objective To compare the clinical effects between the two-level ladder ultrafiltration and sequential dialysis for hemodialysis patients with excessive water retention.Methods According to our hospital standard,23 patients with water retention during treatment with dialysis from January 2010 to September 2011 were selected.And they conducted a total of 198 dialysis.Both the two-level of high-level segment and sequential ultrafiltration step dialysis were set for 1 hour.Ultrafiltration accounted for one-third of the total,and the remaining two-thirds of the amount of ultrafiltration was completed in the remaining time.The blood pressure,ultrafiltration volume completed,plasma osmotic pressure,detection of vascular access pressure,and other observed indicators during dialysis were compared.Results The occurrence of hypotension and muscle spasms in two-level ladder ultrafiltration was slightly more than that in sequential dialysis,ultrafiltration volume completed actually in two-level ladder ultrafiltration was a little less than sequential dialysis.However,the difference was not statistically significant ( P ＞ 0.05 ).It took more time during sequential dialysis simple ultrafiltration,occasionally dialysis fluid stopped flowing and dialyzer and the trail tube lack of incubation,and some patients could not adapt to it.Amount of heparin( [7.48 ± 1.73 ] mg/h vs[6.25 ± 1.36] mg/h,t =5.374,P ＜ 0.01 ),venous pressure ( [ 128.62 ± 10.53 ] mm Hg vs [ 96.35 ± 11.84 ] mm Hg,t =20.166,P ＜ 0.01 ),trausmembrane pressure( [ 236.84 ± 23.65 ] mm Hg vs [ 175.94 ± 24.72] mm Hg,t =17.516,P ＜ 0.01 ) were significantly higher than those in the high level of ultrafiltration period.Mean arterial pressure ( MAP ) ( [ 100.48 ± 5.78 ] mm Hg vs [ 102.54 ± 5.39 ] mm Hg,t =2.571,P ＜ 0.05 ) and plasma osmotic pressure ( [ 311.42 ± 7.36] mOsm/( kg · H2O ) vs [ 3 1 7.31 ± 6.89 ] mOsm/( kg · H2O ),t =5.774,P ＜ 0.01 ) in high level period were significantly lower than those in the singal ultrafiltration period,and the MAP difference was higher than that in the singal ultrafiltration period ( [ 11.46 ± 6.53 ] mm Hg vs [ 9.42 ± 5.46 ] mm Hg,t =2.385,P ＜ 0.05 ).There is less symptomatic hypotension and other adverse reactions.Conclusion Two dialysis ultrafiltration method can both be used for patients with excessive water retention,they can reduce the ultrafiltraion complications and achieve ultrafiltration targets.Two-level ladder ultrafiltration with dialysis and ultra.filtration unity is more likely to be adopted by the clinic.

Objective To realize the clinical characteristics of fungemia in premature infants.Methods Clinical characteristics of fungemia in premature infants in the intensive care unit of a children''s hospital between January 2011 and December 2015 were analyzed retrospectively, general condition of premature infants, laboratory-related indicators, and antimicrobial susceptibility testing results were compared.Results From January 2011 to December 2015, 42 premature infants with confirmed fungemia were treated in this hospital, 22 (52.38％) of whom were with fungemia caused by Candida albicans(C.albicans), 13 (30.95％) by Candida parapsilosis (C.parapsilosis), 3 by Candida krusei (C.krusei), and 4 by other fungi.Patients were grouped according to the main pathogens causing infection: C.parapsilosis group and C.albicans group.Maternal genitourinary tract infection rate and incidence of fungal meningitis in C.albicans group were both higher than C.parapsilosis group(27.27％ vs 7.69％, 27.27％ vs 0.00％ respectively), peripherally inserted central catheter (PICC) rate in C.albicans group was lower than that in C.parapsilosis group(22.73％ vs 69.23％), platelet count in C.parapsilosis group was lower than C.albicans group, differences were all statistically significant (all P<0.05).Conclusion The major fungi causing fungemia in premature infants were C.parapsilosis and C.albicans, maternal reproductive system infection during pregnancy can easily lead to candidemia, premature infants with candidemia are more vulnerable to developing fungal meningitis;PICC is more likely to lead to C.parapsilosis fungemia, and platelet decline is more obvious.

Objective To predict the biological process and signaling pathways in which hsa-miR-1908 might be in-volved by a series of bioinformatics analysis, so as to lay foundations and provide theoretical basis for the further studies of hsa-miR-1908 biological function in human preadipocytes. Methods The sequence of hsa-miR-1908 was acquired from miR-Base database, and target genes of hsa-miR-1908 were predicted by miRanda, and then the intersection of the results and the results of gene-chip as gene set were further analyzed by gene ontology and pathway enrichment. Results The hsa-miR-1908 had some conserved property among different species. The functions of the target genes were enriched in Wnt receptor signal-ing pathway through beta-catenin, cell cycle, cell apeptosis and other biological processes. The GnRH signaling, MAPK sig-naling, insulin signaling, cell cycle signal transduction pathways and signaling pathway in pancreatic cancer were signiifcantly enriched. Conclusions The target genes set of hsa-miR-1908 were enriched in multiple biological process which are related with the obesity. This study provides guidance for the further study in human preadipocytes.

Objective To investigate the inlfuence of overexpression of miR-26b on the secretion of adipokines dur-ing human adipocyte differentiation. Methods Human preadipocytes were infected with the hsa-miR-26b over-expressing lentivirus and were induced to differentiate, and then the levels of adipokines (IL-6, leptin, resistin, TNF-α) at different time points during differentiation were measured by ELISA. Results Compared with control group, decreased secretions of both IL-6 and leptin, and increased secretion of resistin were found during the differentiation of human adipocytes in miR-26b overexpressed group. However, the secretion of TNF-αwas not measured in both groups. Conclusion The miR-26b can improve the inlfammation and insulin resistance of human adipocytes, which will provide potential targets for obesity treat-ment.
