OBJECTIVE:To observe analgesic effect and safety of ketorolac tromethamine combined with butorphanol tartrate in the treatment of acute pain after fracture surgery. METHODS:76 acute pain patients after fracture surgery were selected and ran-domly divided into control group and observation group,with 38 cases in each group. Control group was given Ketorolac trometh-amine injection 30 mg,ivgtt,and then 2 ml/h,0.5 mg/kg,ivgtt;observation group was additionally given butorphanol tartrate 10 mg,ivgtt,on the basis of control group. Pain degree was evaluated with VAS before and 10 min,1,2,4 and 6 h after treatment, and the occurrence of ADR was observed in 2 groups. RESULTS:10 min,1,2,4 and 6 h after treatment,VAS score of 2 groups were significantly lower than before,with statistical significance(P<0.05);6 h after treatment,VAS score of observation group was significantly higher than that of control group,with statistical significance (P<0.05);there was no statistical significance in VAS score between 2 groups 10 min,1,2 and 4 h after treatment (P>0.05). The incidence of ADR in observation group (5.26%)was significantly lower than in control group(21.05%),with statistical significance(P<0.05). CONCLUSIONS:Com-pared with ketorolac tromethamine alone,ketorolac tromethamine combined with butorphanol tartrate shows shorter analgesia dura-tion,similar therapeutic efficacy,and lower incidence of ADR.

Objective To investigate the prognostic factots by analyzing clinicopathologlcal characteristics of 972 cases of colonic carcinoma. Methods Clinical and pathological data of 972 patients with colonic carcinoma treated surgically were studied by univariate and multivariate analysis,survival rate was calculated by life-table method and compared by Log-rank test. Results The univariate analysis indicated that the predictors of survival were age,perioperative blood transfusion, perioperative carcinoembryonic antigen(CEA)level,tumor gross type,depth of tumor invasion,lymphatic invasion,liver metastasis,extrahepatic metastasis,local recurrence、peritoneal seeding,pathological type,TNM stage and type of lymph node clearance.The multivariate analysis indicated that the independent predictors of suivival were age,periopemtive CEA level,tumor gross type,lymphatic invasion,liver metastasm,extrahepatic metastasis,local recurrence、peritioneal seeding,pathological type,type of lymph node clearance and TNM stage. Confclusions Lymphatic invasion is the most important independent prognostic factor of patients with colonic carcinoma treated surgically.

Objective To observe the long-term effect of suramin on the inhibition of proliferation of human retinal pigment epithelial (RPE) cells in vitro. Methods RPE cells grown in 9 pieces of 96-well plate (12 wells each plate) were divided into experimental and control group, with 6 wells in each group. The concentration of 0.1 ml RPE cells in each well is 5?104 cells/ml. After the change of the medium, RPE cells were treated with suramin (250 ?g/ml) in experimental group while treated with nothing in the control group. The medium of the 2 groups were changed to the normal medium after 4 days. At the 1~st , 2~nd , and 4~th day after the addition of suramin and at the 1~st , 2~nd , 3~rd , 5~th , 6~th , 7~th , 9~th , 11~th and 13~th day after removing suramin, 1 plate was randomly selected to stop culturing, and the proliferation of RPE cells were detected by methyl thiazolyl tetrazolium (MTT) assay. Results Under reversed microscope, RPE cells in control group were fused completely at the 7~th day after inoculation. The extracellular space of RPE cells in experimental groups was larger than that in the control group, and remained unfused at the 13~th day after inoculation. The inhibitory rate of proliferation of RPE cells at the first day after treated with suramin was 14.85% and increased to the highest 25.79% at the 4~th day. The first day after the suramin-containing media was removed, the inhibitory rate decreased to 12.35%, and then raised gradually to over 20% at the 3~rd to 5~th day. Finally, the rate drop to 14.71%. Conclusion Suramin has the long-term effect on the inhibition of RPE cells induced by serum, especially the inhibitive effect after the remove of suramin, which indicates the specific double-peak inhibition during the whole process.

Aim To investigate the interaction between regulatory proteins related to the activation of eNOS and CYP4A/20-HETE.Methods The endothelia of pulmonary artery of new born bovine were cultured and divided into four groups: controlling group: ethanol solvent as vehicle (the volume is the same with 1?10~ -6 mol?L~ -1 20-HETE) was added to culture dish and incubated for 10 min; 20-HETE 5 min treatment group:1?10~ -6 mol?L~ -1 20-HETE was added to culture dish and incubated for 5 min; 20-HETE 10 min treatment group:1?10~ -6 mol?L~ -1 20-HETE was added to culture dish and incubated for 10 min; VEGF 10 min treatment group: 1?10~ -8 mol?L~ -1 VEGF was added to culture dish and incubated for 10 min. CYP4A,eNOS and proteins related to the activation of eNOS were measured by Immunoprecipitating and immunobloting.Results Expressions of eNOS and phospho-eNOS(Ser1177)in PAECs were upregulated after the cells were treated with 20-HETE, and similar phenomena were observed when 20-HETE was replaced by VEGF; 20-HETE increased the binding of Hsp、Akt and eNOS.Conclusions ①20-HETE phosphorylates eNOS at Ser1177 site which activates the eNOS to catalyze L-aginine to produce nitric oxide.②eNOS binds with Hsp90 and Akt in endothelial cell of pulmonary artery and 20-HETE increase the binding. ③eNOS binds with CYP4A in endothelial cell of pulmonary artery.

Objective To explore the relationship between ischemia/reperfusion (IR) and the expression ET-3 and GFAP. Methods Thirty-six adult male mice were randomly divided into three groups: ⑴ ischemia/reperfusion group(IR,n=24), bilateral common carotid arteries(BCCA) of mice were ligated for 7 minutes and reperfused for 1day,3day,5day and 10day; ⑵ a sham operation group (SO, n=6); ⑶ normal control group(NG, n=6). The ET-3 and GFAP expressions in the layers Ⅲ-Ⅵ of frontal and parietal lobes of mice in the three groups was detected by immunohistochemisty.

Objective To observe the ultrastructural characteristics of human retinal progenitor cells cultured in vitro. Methods Six 5-month-old human fetuses(12 eyes)without eye diseases were selected. Retinal progenitor cells from the retina of one eye of each fetus were cultured in vitro,and observed by transmission electronic microscopy(TEM); while those from the other eye were directly observed by TEM. Results Abundant heterochromatin were found in the karyon of 5-month embryonic retinal neuroepithelial cells,and the figure of the karyons was irregular.A few scattered initial cells were seen in retinal neuroepithelial layer with large karyon,smooth surface,abundant euchromatin,and distinct nucleolus.The human retinal progenitor cells cultured in vitro had the same ultrastructural characteristics as the initial cells:with huge karyon which almost occupied the whole cell,little cytoplasm,distint nucleolus,abundant euchromatin,and little heterochromatin.The cells clung to each other in the neural globoid cell mass.The size of the outer cells was large,and karyokinesis could be found. Conclusion The cultured human retinal progenitor cells are provided with the same ultrastructure characteristics as the initial cells.

Objective To determine whether the antiserum produced by immunizing mice with conotoxin GI coupled with bovine serum albumin (BSA) could neutralize GI conotoxin.Methods The GI-BSA was prepared by glutaraldehyde-coupled method,and the mice were immunized with the GI-BSA to produce antiserum.The antibody neutralization assay was used to test the detoxication of the antiserum.Results The SDS-PAGE protein electrophoresis showed that the coupling reaction of GI hapten with BSA was successful.The two distinct protein bands of GI-BSA were more than 120×103.Each mouse was immunized four times with 99 μg every two weeks.After the fourth immunization,the serum neutralization titer was more than 1:64 000.After the intraperitoneal injection of the mixture of 100 or 200 μl of the antiserum and different doses of GI,75% of the mice survived in the group with 100 μl of the antiserum and 1× LD50 GI(16.3 μg/kg).The same percentage of mice also survived in the group of with 200 μl of serum and 25.8 μg/kg of GI.Conclusion The antiserum produced by immunizing mice with GI-BSA exhibits significant detoxication activity to conotoxin GI.

Objective To evaluate the effect of bifidobacterium-mediated CTP-NPRL2 on the growth and apoptosis of nude mouse renal carcinoma.Methods Recombinant plasmid pET15b-CTP-NPRL2 was constructed and transfected into bifidobacterium by electroporation,and then the expression of fusion protein CTP-NPRL2 was verified by Western blot.The nude mouse renal carcinoma model was constructed by subcutaneous injection of renal carcinoma cells suspension.The nude mice with renal carcinoma were equally and randomly divided into the observation group and control group(8 mice in each group).The mice in the observation group were treated with bifidobacterium containing recombinant plasmid pET15b-CTP-NPRL2 through tail vein injection,and the mice in the control group were treated with normal saline.All mice were treated once a week for four weeks,and then executed for evaluating the weight of mice and bearing tumors.Finally,the apoptosis of renal carcinoma was detected by TUNEL staining.Results The mass of nude mice was(26.24±1.98) g in the observation group and(23.28±2.17) g in the control group.The mass of bearing tumors was(1.37±0.12) g in the observation group and(1.68±0.18) g in the control group,and the differences were statistically significant(P＜0.05).The TUNEL detection results showed that the apoptosis index of renal carcinoma cell in the observation group(23.27±5.14)％ was significantly higher than that in the control group(10.37±2.58)％,and the difference was statistically significant(P＜0.05).Conclusion Bifidobacterium-mediated CTP-NPRL2 has an inhibitory effect on the renal carcinoma growth of nude mouse,and significantly increases the apoptosis of renal carcinoma cells.

Objective To study the effects of Qingjinkangkuoyin (QJKKY) on TNF-α and NE in rats with bronchiectasis.Methods Models were established by intrabronchially injecting with pseudomonas aeruginosa,and divided into 5 groups by random:the QJKKY high dose treatment group (given high dose of QJKKY into stomach),the QJKKY low dose treatment group (given low dose of QJKKY),the levofloxacin group (given levofloxacin),the model group (given normal saline),and the normal contrast group (given normal saline).After 2 weeks of treatment,the histopathology of lung tissue,the levels of TNF-α and inflammatory cells in peripheral blood and NE in rats' lung tissue were detected.Results Compared with the model group (160.425±9.9293)ng/L,QJKKY could decrease the level of TNF-α in blood significantly [high dose of QJKKY treatment group was (137.133±6.1646)ng/L,P＜0.05]; the expression of inflammatory cells in serum were decreased significantly by QJKKY [high dose of QJKKY treatment group was (1.106± 0.3580) 109/L,P＜0.05].Low dose of QJKKY treatment group was (1.086 ±0.2433) 109/L,(P＜0.05) ; the expression of NE in lung tissue were decreased remarkably by QJKKY [high dose of QJKKY treatment group(80.697 ±4.5877)ng/L,P＜0.05]; low dose of QJKKY treatment group is (80.747±3.6925)ng/L,(P＜0.05); and the histopathologic change of lung tissue in QJKKY treatment groups were ameliorated under light microscope by HE staining.Conclusion Qingjinkangkuoyin could cure bronchiectasis by decreasing the expression of TNF-αin peripheral blood and NE in rats' lung tissue.
