Objective To observe the effect of intravenous small dose of ketamine combined with continuous infusion of propofol and sufentanyl in painless gastroscopy.Methods 62 patients undergoing painless gastroscopy under intravenous anesthesia were randomly divided into the control group and ketamine group with 31 cases in each group. The cases of the control group were treated with continuous infusion of propofol (target controlled infusion rate: 3.0 μg/ml) and sufentanyl (loading dose: 0.15 μg/kg, basal rate 0.15 μg/kg/h); those of the ketamine group were treated with intravenous small dose of ketamine 0.5 mg/kg combined with continuous infusion of propofol (target controlled infusion rate: 3.0 μg/ml) and sufentanyl (loading dose: 0.1 μg/kg, basal rate 0.1 μg/kg/h). The procedure of gastroscopy was started when patients were in unconsciousness and their vital signs were stable, and the infusion of medicine was stopped when the gastroscopy was finished. The systolic blood pressure (SBP) and heart rate (HR) at the time of before anesthesia, 1 minute after anesthesia, inserting the gastroscope, 10 minutes after inserting the gastroscope, and recovering from the anesthesia were recorded. The cases needing special respiratory management (SRM), displaying body movement (BM) in gastroscopy and post-operative nausea and vomiting (PONV) were recorded. The recovery time (RT) after gastroscopy was also recorded.Results No significant difference was found in SBP, HR, BM, PONV and RT between two groups ( P>0.05). Eight cases in the control group and one case in the ketamine group needed SRM before inserting the gastroscope due to transient respiratory depression ( P<0.01).Conclusion The application of intravenous small dose of ketamine combined with continuous infusion of propofol and sufentanyl in painless gastroscopy is effective and safe.

Leptin,a polypeptide hormone coded by Ob-gene,has the functions of depressing appetite,reducing caloric intake and enhancing caloric consumption,etc.Leptin has a close relationship with kidney,for it is metabolized and eliminated via kidney.Meanwhile,leptin can also directly affect kidney functions,influencing the process of chronic renal failure.Furthermore,hyper-leptinemia is associated with anorexia,malnutrition and cardiovascular diseases.Different dialysis patterns may also play different roles in cleaning leptin.For example,common dialysis could not clear leptin,but other dialysis modes such as high permeability dialysis,hemodiafiltration,and mastic absorption hemoperfusion can alleviate hyper-leptinemia through cleaning leptin partly.For kidney transplantation patients,hyper-leptinemia may affect the immune balance which has been maintained for a long time.

OBJECTIVE:To study the new formula of effective components in TCM for anti-allergic rhinitis (AR),and pro-vide reference for developing TCM preparations for anti-AR. METHODS:Using pseudoephedrine hydrochloride (0-13.5 mg/kg), total alkaloid extracts of Aconitum carmichaelii (0-21.18 mg/kg),volatile oil of asari radix (0-0.0092 mL/kg) in Mahuang Fuzi Xixin decoction as formula objects,uniform design method was used for drug grouping,and multiple regression analysis was con-ducted for the behavioral scores before and after administration,contents of histamine and immunoglobulin E (IgE) in serum of AR guinea pigs to obtain the best formula. Using Xinqin granule,Loratadine tablet,Mahuang Fuzi Xixin decoction respectively as positive control,efficacy of the best formula was verified from aspects of behavioral scores before and after administration,con-tents of histamine and IgE of AR guinea pigs. And the safety of the best formula was preliminarily observed through acute toxicity test in mice. RESULTS:The best formula was as follow as pseudoephedrine hydrochloride 11.25 mg/kg,total alkaloid extracts of A. carmichaelii 21.18 mg/kg,volatile oil of asari radix 0.0045 mL/kg. Compared with each positive drug group,there were no sig-nificant differences in behavioral scores before and after administration in the best formula group(P>0.05). While compared with Xinqin granule group and Mahuang Fuzi Xixin decoction group,histamine content in serum in the best formula group was signifi-cantly reduced (P<0.05);compared with Xinqin granule and Loratadine tablet group,IgE content in serum in the best formula group was significant decreased (P<0.05). Median lethal dose of the best formula was 1822.04 mg/kg. CONCLUSIONS:The screened best formula shows better effect than Xinqin granule and Mahuang Fuzi Xixin decoction in terms of reducing histamine content in serum,better than Loratadine tablet and Xinqin granule in terms of reducing IgE content in serum,with good safety, which indicates the feasibility of TCM effective component formula to a certain degree.

Objective To investigate the effects of iodine excess on spleen cell viability,lactate dehydrogenase (LDH) leakage,mitochondrial superoxide production and peroxiredoxin (Prx)3 expression in methallothionein Ⅰ / Ⅱ knockout (MT-Ⅰ / Ⅱ KO)mice.Methods Spleen cell suspensions were prepared from six to eight-week old and healthy male MT-Ⅰ / Ⅱ KO mice and wild type (WT) mice; the cell number was adjusted to 5 × 107/L and the cells were plated in 96-well plates (100 μl each well); the cells were exposed to various concentrations of KI (0,10-4,10-3,10-2 mol/L) and 10-3 mol/L H2O2,respectively,for two hours,and control group did not give KI nor H2O2.Cell viability was assayed by methyl thiazolyl tetrazolium (MTT) colorimetric method.Cell damage was detected by chemical colorimetric method.Mitochondrial superoxide production in the spleen cells was measured by flow cytometry.Western blotting technology was used to investigate the expression of Prx3.Results In both MT-Ⅰ/Ⅱ KO and WT mice,the differences of cell viability,LDH leakage,mitochondrial superoxideproduction and the expression of Prx3 of spleen cells among the treatment groups were statistically significant (F =357.92,71.03,130.36,10.36,179.58,26.92,187.43,and 7.16,all P ＜ 0.05).Compared to the control group [(100.00 ± 2.00)％,(100.00 ± 1.63)％,(3 202.22 ± 85.63),(3 161.51 ± 144.49)U/L,43.82 ± 1.56,38.60 ± 2.81,0.61 ± 0.09,0.50 ± 0.08],cell viability of 10-4,10-3,10-2 mol/L KI treatment and 10-3 mol/L H2O2 groups [(80.77 ± 1.86)％,(89.89 ± 2.90)％,(76.08 ± 1.92)％,(87.66 ± 1.74),(73.26 ± 1.86)％,(84.30 ± 2.23)％,(66.22 ± 1.71)％,(70.80 ± 1.49)％] was decreased (all P ＜ 0.05); LDH leakage [(3 880.00 ± 190.62),(3 431.17 ± 170.45),(4 178.33 ± 170.43),(3 598.63 ± 189.09),(4 388.61 ± 123.79),(3 863.72 ± 195.64),(4 615.28 ± 196.17),(4 148.12 ± 195.81)U/L] was increased significantly (all P＜ 0.05); and mitochondrial superoxide production in the spleen cells (53.83 ± 3.22,47.03 ± 1.60,58.92 ± 4.00,50.48 ± 2.59,72.72 ± 2.14,68.53 ± 2.97,80.76 ± 4.11,75.26 ± 3.41) was increased significantly (all P ＜ 0.05); Prx3 expressions in 10-3、10-2 mol/LKI and 10-3 mol/L H2O2 treatment groups (0.82 ± 0.12,0.65 ± 0.12,0.96 ± 0.15,0.73 ± 0.16,1.04 ± 0.13,0.85 ± 0.16) significantly increased (all P ＜ 0.05),the differences of Prx3 expressions between 104 mol/L KI groups (0.73 ± 0.15,0.55 ± 0.09),and control groups were not statistically significant (all P ＞ 0.05).In 104,10-3,10-2 mol/L KI and 10-3 mol/L H2O2 treatment groups,cell viability of MT-Ⅰ/Ⅱ KO mice spleen was lower than that of WT mice (t =6.47,10.93,9.30 and 4.96,all P ＜ 0.05); LDH leakage was higher than that of WT mice (t =4.30,5.58,5.56 and 4.13,all P ＜ 0.05); mitochondria superoxide production was higher than that of WT mice (t =4.64,4.33,2.80 and 2.52,all P ＜ 0.05); Prx3 expression was higher than that of WT mice (t =2.54,2.37,2.59 and 2.27,all P ＜ 0.05).Conclusions KI may decline the cell viability,increase the leakage of LDH and increase the production of mitochondrial superoxide production and Prx 3 expression,which are much more significant in MT-Ⅰ /Ⅱ KO mice,suggesting that MT Ⅰ /Ⅱ has some antioxidative effect in high concentration of iodide induced oxidative stress in the spleen.

Objective p38 Mitogen-activated protein kinase (MAPK) is a crossing center of various pathways. In this study, protein transduction system based on human immunodeficiency virus (HIV)-1 transactivator of transcription (TAT), which is an efficient delivery peptide of the foreign proteins into cells, was employed to study p38 MAPK functions in eukaryotic cells. Methods p38 And its dominant negative form, p38AF, were constructed into pET-His-TAT vector correctly to verify that the recombinant plasmids were well-founded through restriction enzyme digestion and DNA sequencing. The two proteins, His-TAT-p38 and His-TAT-p38AF, were expressed and purified in Escherichia coli by SDS-PAGE. Then they were incubated with ECV304 cells respectively and readily transduced into cells in a time-dependent and dose-dependent manner. The cells were stimulated by sorbitol. Activating transcription factor (ATF) 2 phosphorylation level was checked using Western blot to assess the activity of endogenous p38. Results Compared with controls, it was found that His-TAT-p38 increased the level ofATF2 phosphorylation in sorbitol-stimulated ECV304 cells, while His-TAT-p38AF inhibited it, indicating p38 MAPK protein delivery system based on TAT was constructed successfully. TAT-p38 and its dominant negative form possessed high biological activity after transduction into ECV304 cells by TAT protein delivery system. The results showed that p38AF fused with TAT could inhibit the transduction of endogenous p38 signal pathway in part, and other pathway might regulate p38 phosphorylation. Conclusions Our study provides a novel pathway to inhibit p38 signal pathway and establish a new method to study p38 function.

Aim To observe the effect and primary mechanism of arctigenin ( ARG) in C6 rat glioma. At the same time, to investigate the effect of ARG com-bined with temozolomide. Methods C6 glioma rat model was established, and 90 rats were divided into six groups, which were subcutaneously administered with model, low and high ARG (0. 05 and 0. 1 mg· kg-1 , sc) , temozolomide (20 mg·kg-1 , p. o. ) , low ARG combined with temozolomide(TMZ / ARG 0. 05) and high ARG combined with temozolomide ( TMZ /ARG 0. 1 ) . The tumor specimens of brain were col-lected after tumor graft. Proliferating cell nuclear anti-gen ( PCNA ) , glial fibrillary acidic protein ( GFAP ) and CD40 in tumor specimens were determined by im-munohistochemistry. Results ① Compared with the model group, the tumor sizes of rats in the arctigenin treatment groups were decreased ( P<0. 05 ) . ②ARG
significantly decreased PCNA and CD40 expression ( P<0. 05 ) and increased GFAP expression ( P<0. 05 ) .③ Compared with model group, arctigenin combined with temozolomide decreased the tumor sizes ( P <0. 01 ) , and the tumor inhibition rate was higher than that of the arctigenin and temozolomide. At the same time, arctigenin combined with temozolomide de-creased PCNA and CD40 expression ( P <0. 01 ) and increased GFAP expression ( P <0. 05 ) , which was better than arctigenin and temozolomide. Conclusion Arctigenin inhibits rat glioma growth, and synergizes with temozolomide, which may be associated with in-hibiting PCNA and CD40 expression and strengthening GFAP expression.
