Objective To compare the effects of patient's tolerance to laryngeal mask airway (LMA) and tracheal tube (TT) on the appropriate level of sevoflurane anesthesia.Methods Eighty ASA Ⅰ or Ⅱ patients aged 30-60 yr weighing 50-70 kg undergoing elective thyroid or breast surgery were randomly divided into 2 groups (n=40 each):LMA group and TT group.Anesthesia wag induced with propofol 1.6mg/kg,fentanyl 3μg/kg and recuronium 0.6mg/kg.LMA or tracheal tube was inserted,and the patients were mechanically ventilated.Anesthesia was maintained with inhalation of 1.5%-3.0% sevoflurane and 50% N2O in O2 in group LMA,and with 2.5%-5.0% sevoflurane and 50% N2O in O2 in group TT.The flow of O2 and N2O was 0.7-1.0L/min,and the concentration of sevofluranee was adjusted to maintain AAI at 15-25.ECG,HR,MAP,SpO2,PETCO2,AEP and end-tidal sevoflurane concentration were continuonsly monitored.The end-tidal sevoflurane concentration was recorded at 1,5 and 10 min after LMA/TT was placed (T1-3),at 1h after skin incision (T4) and at the end of operation before removal of LMA or extubation (T5).The recovery time of consciousness,adverse cardiovascular events and adverse reactions were recorded.Results The end-tidal sevoflurane concentration was significantly lower,the recovery time of consciousness and removal of LMA or extubation time were shorter,and the incidence of adverse cardiovascular events and adverse reactions was lower in LMA group than in TT group.Conclusion At the same depth of anesthesia (AAI 15-25),sevoflurane concentration is significantly lower in LMA group than in TT group,with fewer complications and smaller cardiovascular reaction.

OBJECTIVE:To prepare Weiyoukang intragastric floating tablet,and to investigate in vitro releasing characteristics of it. METHODS:Weiyoukang intragastric floating tablet was prepared by full powder compression method using HPMC-K15M (framework material),octadecanol(low density bleaching promoter),sodium bicarbonate(foaming agent),PVP-K30(release reg-ulator)and magnesium stearate(lubricant)as excipients. The amounts of HPMC-K15M,octadecanol and PVP-K30 were optimized by orthogonal test and validated with 2 h,4 h and 8 h accumulative release rate of berberine (Y2 h,Y4 h,Y8 h) as index,start time (T1)and duration(T2)of floating as adjunctive index. The releasing regularity of berberine,tetrahydropalmatine,baicalin and glyc-yrrhizic acid in Coptis chinensis,Corydalis vanhus,Scatellaria baicalensis and Glycyrrhiza uralensis were measured by release model fitting method and Peppas equarion fitting method. Similar factor(f2)method was used to investigate the similarity of 4 com-ponents. RESULTS:The optimized formulation was as follows as HPMC-K15M 40 g,octadecanol 14 g,PVP-K30 2 g for 200 tab-lets. Y2 h,Y4 h and Y8 h of berberine of preparations were 31.94%,55.88%,93.34%(RSDs were 1.2%,1.5% and 1.5%,n=3),re-spectively. T1 and T2 were about 1 min and 13 h. The drug release of four ingredients all fitted Higuchi models,and were synergis-tic action of diffusion and matrix erode. The f2 were all more than 80,indicating that the release of four ingredients were similar. CONCLUSIONS:Weiyoukang intragastric floating tablet is prepared successfully,showing fast onset,long floating,sustained-re-lease and balanced release of multiple indigents.

Objective To detect the expressions of vascular endothelial growth factor(VEGF) and Periostin in patients with diabetic retinopathy (DR),and to explore its chnical significance.Methods A total of 52 patients with DR (DR group),36 non-DR diabetic patients (non-DR group) and 30 healthy person (normal control group) were enrolled.The 52 cases of DR patients were divided into non-proliferative DR (PDR) group (non-PDR group,24 cases) and PDR group (28 cases).The expressions of serum VEGF and Periostin were detected with enzyme-linked immunosorbent assay analysis.Results The serum expressions of VEGF and Periostin were significantly higher in non-DR group and DR group than those in normal control group [(122.63 ±28.74),(163.58 ±42.37) mg/L vs.(91.53 ± 19.58) mg/L,(110.15 ±32.62),(146.51 ± 41.74) mg/L vs.(82.26 ± 21.17) mg/L,P ＜ 0.05 or ＜ 0.01].The serum expressions of VEGF and Periostin were significantly higher in DR group than those in non-DR group (P ＜0.05).The serum expressions of VEGF and Periostin were significantly higher in PDR group than those in non-PDR group [(174.15 ±47.31) mg/L vs.(147.66 ±38.25) mag/L,(160.31 ±46.43) mg/L vs.(132.14 ±35.62)mg/L,P ＜ 0.05].The serum expression of VEGF was positively related with Periostin (r =0.415,P ＜ 0.01).Conclusion The high-expressions of VEGF and Periostin are found in DR patients,and which maybe play a key role in the early diagnosis and assessment the progression of DR patients.

Objective To investigate the effects of electro-acupuncture on gastric emptying and Fos expression in the neuron of vagal-solitary complex (VSC) of rat bulbus after lipopolysaccharide (LPS) intraperitoneal injection (i.p.). Methods 40 male SD rats were randomly assigned to 4 groups: control group, LPS i.p. group, LPS i.p. plus electro-acupuncture at Tsusanli point group and LPS i.p. plus electro-acupuncture at non-meridian-non-acupoint group, 10 rats for each group. Immunohistochemical techniques were used to detect the Fos expression in VSC. The animal's gastric emptying was measured by phenol red method. Results The rats with gastric emptying decreased greatly to (20.7±4.5)% 2.5 hours after LPS injection, and Fos-positive neurons were significantly found in VSC (83.2±6.6) compared with control group. However, in the group of LPS i.p. plus electro-acupuncture at Tsusanli point, the gastric emptying was up-regulated to (44.1±6.2)%, and the expression of Fos -positive neurons were down-regulated to (37.9±3.8) compared with LPS i.p. group. No significant difference was found between the group of LPS i.p. plus electro-acupuncture at non-meridian-non-acupoint and the group of LPS i.p. Conclusion LPS i.p. can retard the gastric motility in rats, electro-acupuncture at Tsusanli point may well regulate the function in LPS model rats. This function may be connected with its protective effects on Fos immunoreactive neurons activity in VSC of rat bulbus.
