Acute respiratory distress syndrome (ARDS) is a serious state threaten human health with a high mortality about 30%-40%. At present, there is no effective treatment for ARDS. Microvesicles derived from mesenchymal stem cells (MSC-MVs) have a heterogeneous subcellular structure secreted by MSCs. It plays an important role in the repair of tissue and organ damage.Recent studies have shown that MSC-MVs, played an important role in repairing lung injury, may replace MSC for cell therapy. Therefore MSC-MVs may bring new hope for ARDS treatment.

Objective To test the efficiency of gene transfer and expression mediated by ultrasound and microbubble strategy in 293T cell. Methods SonoVue microbubbles were mixed with pla.smid DNA encoding hAng-1 and green fluorescent protein. The mixture of the DNA and microbubbles was administer to cultured 293T cells by ultrasound exposue. The ultrasound condition was 1. 5 W/cm~2 and 30 s. Forty eight hours later, transfer rate was assessed by fluorescence microscopy and flow cytometry. Cell viability was assayed by Trypan Blue staining. RT-PCR and Western blot analysis was used to examine the expression of hAng-1 mRNA and protein. Agarose gel electrophoresis was used to evaluate the integrity of the plasmid. Results The transfection expression rate of eGFP in 293T cells was markedly increased with the additon of 20% microbubbles and 15 mg/L DNA. Fetal calf serum had no influence on the gene transfer rate. Ultrasound irradiation combined with microbubbles couldn't destroy the integrity of plasmid. Conclusions Ultrasound-mediated microbubbles destruction can increase the transfection and expression of hAng-1 gene in 293T.

Objective To investigate the effects of ultrasound and microbubbles on transient transfection of angiopoietin-1(Ang-1) into vascular endothelial CRL1730 cells and the effects of cell migration. Methods CRL1730 cells were divided into four groups:a control group (without any treatment), an Ang-1 group (with Ang-1 added only), a microbubble group (with only microbubbles added) and an ultrasound with microbubbles group (Ang-1, microbubbles and 1 MHz ultrasound irradiation for 30 s). All were cultivated for 24 h. The expression of Ang-1 mRNA and protein were measured using RT-PCR and Western blotting. The cells' migration ability was detected using the Transwell method. Results There was no difference in the expression of Ang-1 mRNA or protein among the control group, the Ang-1 group and the microbubbles group, but the expression of Ang-1 mRNA and protein was increased significantly in the ultrasound plus microbubbles group. Cell migration ability was also enhanced significantly in the ultrasound and microbubbles group compared with the other groups. Conclusion A combination of ultrasound and microbubbles might successfully transfect Ang-1 genes into vascular endothelial cells, and the migration ability of the transfected cells is also enhanced.

Objective To explore the capability of Ang-1 gene delivery to acute myocardial infarction using targeted microbubbles carrying ICAM-1 antibody.Methods Thirty-seven rabbits' left circumfles branch coronary arteries were ligated for models.Three rabbits were injected with microbubbles carrying ICAM-1 to detect the ability of targeting.Thirty-four rabbit models were divided into 3 groups randomly as follow:IM group (n=12,accept direct intramuscular injection),ICAM-1 group (n=12,accept intravenous injection of targeted microbubbles and Ang-1) and control group (n=10,without any treatment).Ultrasonography were executed on all animals before and 2 weeks after the treatment.All rabbits were killed after 2 weeks and examined for Ang-1 mRNA and protein by RT-PCR and Western-Blot respectively.Microvessel density (MVD) counting of infracted myocardium,observed by factor Ⅷ immunochemical staining,was performed to value the proangiogenesis effect of Ang-1 delivered by targeted microbubbles carrying ICAM-1 antibody.The liver and the kidney in ICAM-1 group were taken to assess the systemic delivery.Results IM and ICAM-1 group showed significantly improvement in the ejection fraction (P＜0.05) while control group did not.Ang-1 mRNA and protein could be detected in IM and ICAM-1 group;however,the expression between the two groups showed no siginificant difference.None of the control animals showed Ang-1 expression.compared with ICAM-1 group,the MVD was greater in IM group.Ang-1 was not detected either in liver or in kidney in ICAM-1 group.Conclusions Targeted microbubbles carrying ICAM-1 antibody can deliver Ang-1 gene to ischemic myocardium directly.Meanwhile,it's as effective as IM injections besides the greater angiogenesis effect.This strategy improves the perfusion of acute myocardial infarction and the function of heart.

Objective To evaluate subclinical Cushing syndrome cases and to improve the diagnosis.Methods A retrospective analysis was done on the data of 24 subclinical Cushing syndrome cases.Clinical data included clinical manifestations,endocrinal tests,imaging,treatments,light microscopic and electron microscopic results.Results No typical sign of Cushing syndrome was found in these 24 cases.Endocrine tests showed that 24-hour urine free cortisol increased in 18 cases (75%),cortisol rhythm disappeared in 12 cases(50%),high-dose dexamethasone suppression test was not inhibited in 11 cases (46%),and low-dose dexamethasone suppression test (LDDST) was not suppressed in all 24 cases (100%).CT scan showed the average tumor diameter was 3.1(1.8-4.5)cm.Laparoscopic resections of adrenal tumors were performed for all 24 patients.The light microscopic examination of the tumor specimens showed adrenocortical adenoma,and the electron microscopic examination found a greater number of cytoplasmic secretory granules.After 3 months' followup,patient's blood pressure was normal and the normal cortisol rhythm was detected.Conclusions Endocrine tests,especially LDDST,are important for the diagnosis of subclinical Cushing syndrome.Once a clear diagnosis of subclinical Cushing syndrome is established,the patient should be treated with surgery and will have a satisfactory result in both blood pressure control and endocrinal rhythm.

Objective To certificate the effects on transfection ratio and cells viability of ultrasound (US) acoustic intensity, radiation duration, microbubbles concentration and DNA concentration in delivery human angiopioetin-1 gene (hAng-1) into 293T cells by SonoVue microbubbles and decide the optimal transfection parameters. Methods Mix 293T cells and SonoVue microbubbles linked with eGFP-C_3-hAng-1 in a different way, detect the gene transfection ratio and cells viability under the various US intensity, radiation duration, microbubbles and DNA concentrations. Results The gene expression would be increased if enhanced the intenstiy of US,radiation time,microbubbles and DNA concentrations,and the cells viability would be kept more than 90% ( P <0. 01). Whereas,if the US intensity increased over 1. 5 W/cm~2 ,the duration over 30 s and microbubbles and DNA concentrations over 20% and 15 mg/L respectively,the gene expression would not increase significantly ( P > 0. 05),whereas coupled with obviously decreased cells viability( P <0. 01). Conclusions The optimal conditions of deliver hAng-1 gene into 293T cells by SonoVue microbubbles was mixing cells and microbubbles in a cell wall-sticky way,US intensity was 1. 5 W/cm~2, duration 30 s,20% microbubbles and 15 mg/L DNA concentration.

Objective To evaluate the value of the RIFLE criteria of acute kidney injury (AKI) for predicting the incidence and prognosis in critically ill patients and to identify the risk factors associated with the outcomes of those patients.Methods All ICU patients admitted over three years and 6-month period were retrospectively studied at Subei People's Hospital.Based on RIFLE criteria,AKI patients were diagnosed and classified into four groups:NAKI (non-AKI),R (risk),I (injury),F (failure)groups.Results (1) AKI occurred in 404 of the 2472 patients (16.3％) during their ICU stay.The mean age of the patients was (61.4 ± 17.4) years.Infectious disease,pulmonary disease,neurological disease and trauma were the major cause of AKI.(2) Mortality in the ICU was much higher in patients with AKI than in patients without AKI (47.3％ vs.23.0％,P ＜ 0.05).The mortality rate was 35.6％ in R group,48.9％ in I group and 60.6％ in F group.(3) The logistic regression suggested that MODS and septic shock were the independent risk factors of AKI,but continuous renal replacement therapy (CRRT) are the independent protective factor of AKI.Conclusions In these ICU patients,AKI is associated with increased hospital mortality.The RIFLE classification is a simple and useful diagnosis tool to detect and stratify the severity of AKI and aid in predicting outcome of patients.

Objective To investigate the effects of different infusion rates of remifentanil infusion on spontaneous ventilation in children received sevoflurane anesthesia. Methods A total of 120 children underwent strabismus surgery were randomly assigned to four groups: C group (administration of saline), L group (remifentanil 0.03 μg · kg-1 · min-1), M group (remifentanil 0.06μg · kg-1 · min-1) and H group (remifentanil 0.09μg · kg-1 · min-1). The mean blood pressure (MBP), heart rate (HR), respiratory rate (RR), tidal volume (VT), minute ventilation (MV), endtidal CO2 [p(CO2)] and endtidal SEV were recorded after laryngeal mask insertion (T1), an initial bolus dose of remifentanil (T2),10 mins after remifentanil infu-sion (T3),15 mins after remifentanil infusion (T4) and laryngeal mask remove (T5) respectively. The adverse events and time of induction, maintenance and emergence were also recoded. Results There were no significant differences in patient age, body mass index, anesthesia time, operation time, HR and MBP at different time points between four groups. No body movement and hypoxemia were observed. The values of RR and MV at T3, T4 and T5 were significantly lower in H group than those of other three groups (P <0.05). Values of p(CO2)at T3 and T4 were significantly higher in H group than those of other three groups (P<0.05). The values of RR at T3, T4 and T5 were significantly lower in L group and M group than those of C group. The values of MV at T3 and T4 were significantly lower in L group and M group than those of C group. p(CO2)at T4 was significantly higher in L group and M group than that of C group(P<0.05), but no significant difference was found be-tween L group and M group. There was no significant difference in value of VT between four groups. Conclusion Remifent-anil infusion at a rate of 0.03~0.09μg·kg-1·min-1 could depress spontaneous ventilation in children received sevoflurane an-esthesia. The respiratory depression effect is mainly manifested by reduction of RR. It is a good option to choose 0.03~0.06μg · kg-1 · min-1 infusion to keep spontaneous ventilation and avoid severe respiratory depression according to the demand of operations in children.

Objective To evaluate the cost-effectiveness of Morphine-midazolam, propofol and midazolam used for sedation in patients with mechanical ventilation. Methods Ninety-three patients with mechanically ventila-Morphine-midazolam group:priming dose 0.05 mg/kg and 0.05 mg/kg of morphine and midazolam,then continuous The index of ideal level of sedation was on the Ramsay scale. The sedation time, the time from discontinuation to ex-tubation, sedation costs, blood pressure were measured. Results The time in midazolam group (6.0±2.4) h was longer than that of propofol (4.6±1.7) h (P<0.01), but there was no significant relationship between morphine-midazolam group (5.6±2.7) h and midazolam group (4.6±1.7) h (P>0.05). The sedation costs in morphine-mi-dazolam group (101.7±20.4) yuan were lower than those of midazolam group (127.7±21.3) yuan (P<0.05) and propofol group(199.7±65.9) yuan (P<0.01). The ratio of hypotension in propofol group (35.4%, 11/31) hap-pened more frequent than that of midazolam group (3.2%, 1/31) (P<0.01) and morphine-midazolam group (9.7%, 3/31) (P<0.05). Conclusions Morphine-midazolam is a safe, effective and economic drug compared with midazolam and propofol used for sedation in patients with mechanical ventilation.
