Objective To investigate the effect of removing laryngeal mask airway (LMA) in anaesthetized state on emergence agitation after sevoflurane anaesthesia in children.Methods Ninety children with subumbilical operation,ASA Ⅰ or Ⅱ grade,were divided into three groups by random digits table with 30 cases each:ET-A group (endotracheal tube and extubation while awake),ET-D group (endotracheal tube and deep extubation) and LMA-D group (insertion of LMA and deep removal).The incidence of preoperative emotional bad,anaesthesia time,sevoflurane administration time,emergence agitation,the numbers of treated with propofol and/or fentanyl and postoperative anaesthesia care unit(PACU)retention time were measured.Results There was no significant difference in incidence of preoperative emotional bad,sevoflurane administration time and anaesthesia time among the three groups (P ＞ 0.05).The incidence of emergence agitation,the numbers of treated with propofol and/or fentanyl and PACU retention time in LMA-D group were significantly lower than those in ET-A group [26.7％(8/30) vs.66.7％(20/30),8cases vs.20 cases and (23.9 ± 4.9) min vs.(32.9 ± 5.8) min,P ＜ 0.01].Conclusion Insertion of LMA and removing LMA in anaesthetized state can decreased emergence agitation in children after sevoflurane anaesthesia,especially suitable for the children who do not suitable for drug treatment.

BACKGROUND: For decades, liposome drug carrier has been used to enhance drug stability and efficacy, reduce drug toxicity and adverse effects. However, they fail to provide long-term delivery due to insufficient stability. Studies have demonstrated that silica is not toxic, with chemically inert and biological compatibility, and can be used as modified material. OBJECTIVE: To characterize the silica coated liposome and investigate the controlled release property. DESIGN, TIME AND SETTING: In vitro observation. The study was performed at the Nanomedicine and Biosensor Laboratory, Biomedical Engineering Center, Harbin Institute of Technology from May 2007 to June 2008. MATERIALS: Dipalmitoylphosphatidylcholine (DPPC) was purchased from Nanjing Kangsente Chemical Engineering Company; tetraethylorthosilicate (TEOS) was purchased from Aldrich, USA. Doxorubicin (DOX) was purchased from Beijing Huafeng United Technology Company; Sephadex G-50 was purchased from Amersham Biosciences, Sweden. All other chemical agents were of analytical purity. METHODS: Liposome was formed from DPPC following the precipitation of silica by sol-gel method. MAIN OUTCOME MEASURES: Zeta-potential and dynamic light scanning were used for zeta-potential measurement and particle size distribution; transmission electron microscopy was used to collect the image of particle morphology; Fourier transform infrared spectroscopy (FTIR) was used to display chemical characteristics of Si-O-Si structure; Spectrophotofluorimetry was used to determine DOX regression equation and was further used for calculation in drug encapsulation efficiency and in vitro release.　RESULTS: ①Silica coated liposome was successfully prepared. ②FTIR proofed the presence of Si-O-Si at 1 166, 1 080, 859 and 526 cm-1. ③The DOX encapsulated silica coated liposome had encapsulation efficiency of 72.4%. ④Drug release profiles showed that sustained release of DOX was achieved after modification of silica on liposome. CONCLUSION: With Si-O-Si as protective layer, the liposome has increased stability and prolonged drug release.

Objective To explore the relationship between serum uric acid and pulmonary hypertension (PH) in patients with systemic sclerosis (SSc). Methods The echocardiography, electrocardiogram, nailfold videocapillaroscopy and laboratory parameters of 62 patients with SSc were retrospectively analyzed . Patients were divided into two groups according to presence of PH . Statistical analysis was performed using SPSS 17 software . Results Compared to patients without PH , patients with PH had significantly higher serum uric acid levels ( P < 0 . 01 ) , systolic pulmonary arterial pressure ( P < 0 . 01 ) , abnormality of electrocardiogram (P < 0.01), abnormality of nailfold video capillaroscopy and lower serum albunin levels (P < 0.01). Systolic pulmonary arterial pressure had correlation with Serum UA ( r = 0 . 26 , P < 0 . 01 ) as well as serum ablumin (r = -0.28, P < 0.03). Moreover, the mean value of serum UA was significantly different in two ECG groups (P < 0.01) and two nailfold videocapillaroscopy groups (P < 0.01). At the cutoff level of 374 μmol/L, serum uric acid had reasonable accuracy for predicting the presence of PH in SSc patients ( sensitivity 66 . 7% and specificity 84 . 0%) . Conclusion The serum uric acid may be useful as a practicable marker for predict PH in patients with SSc .

Objective To observe the effects of berberine on inflammatory factors, adipokines and fatty acid metabo-lism in 3T3-L1 adipocytes, and to investigate the molecular mechanism underlying berberine’s role of improving insulin re-sistance. Methods mRNA level of inflammatory molecules, adipokines, key enzymes and protein in fatty acid metabolism in 3T3-L1 cells were determined by quantitative real time polymerase chain reaction (qRT-PCR) after cells were treated with different concentrations of berberine (0, 5, 10, 20, 40μmol/L) for 24 hours and with 10μmol/L berberine at different du-rations (0,4,8,24,48 h). These factors mainly included interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), leptin, adipo-nectin, visfatin, fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), adipose triglyceride lipase (ATGL) and adipocyte fatty acid binding protein (AFABP). Results In 3T3-L1 adipocytes, transcription level of IL-6, TNF-α, leptin, FAS, AT-GL, AFABP reduced with addition of berberine dosage at 10~40μmol/L(P＜0.05)while visfatin mRNA level increased(P＜0.05)compared with the control group. No significant difference was found in expression of adiponectin(P>0.05). Tran-scription level of IL-6, TNF-α, leptin, AFABP, ATGL, FAS decreased with time after 10μmol/L berberine intervention (8-48 h) compared with the control group(P＜0.05). On the other hand, visfatin mRNA level increased(P＜0.05)compared with the control group. Adiponectin mRNA decreased only after cells were treated with berberine for 48 h(P＜0.05). No sig-nificant difference was found transcription of ACC between each groups treated with berberine(P > 0.05). Conclusion mRNA level of inflammatory factors, adipokines, key enzymes and protein in fatty acid metabolism in 3T3-L1 adipocytes can be affected by berberine and this effect depend on its dose and time . This might be the mechanisms underlying berber- ine to improve insulin resistance.

Objective:To observe the interventative effect of Ziyin-Huatan Decoction by regulating exosomes on subcutaneous tumor of mice with gastric cancer. Methods:MGC-803 cells were randomly divided into exosome control group, low-dose group and high-dose group. The low-dose group and high-dose group were intervened with Ziyin-Huatan Decoction of 25 μg/ml and 100 μg/ml respectively. After 48 hours, the exosomes secreted by MGC-803 cells in each group were extracted. Twenty BALB/c male mice were randomly divided into exosome control group, low-dose Ziyin-Huatan Decoction group, high-dose Ziyin-Huatan Decoction group and blank control group, with 5 mice in each group. Except for the blank control group, the mice in the other groups were injected with exosomes extracted from the cells of the corresponding group through the orbit, 10 μg/time for each mouse, once every other day, a total of 15 times; the blank control group was injected with the same amount of PBS. Then SGC-7901 cells were inoculated into mice to establish a tumor model. The tumorigenic rate and body weight of mice were observed. The levels of CD31, VEGF and bFGF in tumor tissues were detected by immunohistochemistry. Results:Compared with the blank control group, the tumor weight [(170.00 ± 10.00) mg vs. (343.33 ± 20.82) mg] and the expression of CD31 (37.43 ± 0.55 vs. 63.30 ± 0.85), VEGF (11.37 ± 1.19 vs. 70.30 ± 0.72) and bFGF (43.77 ± 1.53 vs. 84.97 ± 1.86) in the high-dose Ziyin-Huatan Decoction group significantly decreased ( P<0.05). Compared with exosome control group, the expressions of CD31, VEGF and bFGF in low and high dose Ziyin-Huatan Decoction groups were decreased ( P<0.05). Conclusion:Ziyin-Huatan Decoction can significantly inhibit the growth of subcutaneous tumor of gastric cancer in mice by regulating exudation, which may be related to the inhibition of tumor angiogenesis.
