The antagonistic effects of L-THP, Ver and Pap to contraction of isolated guinea pig trachea preparations induced by BaCl2 10-3mol/L ,KC1 3?10-2mol/L, 5-HT 2?10-5mol/L, Ach 2?10-5mol/L and His 2? 10-5mol/L were studied.The antagonistic effects of L-THP were different from Ver and Pap. The IC50 value of L-THP for contraction induced by BaCl2, KC1, 5-HT and His was 3 .5? 10-5mol/L , 4.5 ? 10-5mol/L , 2.5?10-3 mol/L and 8.9? 10-5mol/L respectively. It was showed that sensibility of several agonists to inhibition by L-THP was correlated with dependence of extracellular Ca2+. The potencies of L-THP on anti-KCl and anti-5-HT actions were similar. The results suggested that LTHP possesses anti-calcium and anti-5-HT action on guinea pig trachea.

Objective To explore the relevant factors of hematoma enlargement in patients with hypertensive intracerebral hemorrhage(CH) at acute stage.Methods The clinical data of 208 patients with CH(29 patients with hematoma enlargement) were retrospectively analyzed.Results 27 cases(93.1%)of hematoma enlargement group onset at ≤ 24 h after CH.Compared with non-hematoma enlargement group,systolic blood pressure in the hematoma expansion group was significantly increased;and the rates of Glasgow coma scale(GCS) score decreased,basal ganglia hemorrhage,hepatic dysfunction,long-term alcohol drinking,taking Aspirin and diabetes in hematoma expansion group were significantly higher than those in the non-hematoma enlargement group(P

Objective To observe the metabolism characters of plasma glucagon-like peptide 1 (GLP-1) in surgical critical ill patients.Methods Totally 64 selective surgical patients were prospectively enrolled and randomly divided into two groups:enteral nutrition (EN) group (50％ glucose 100 ml orally administered or through nasogastric tube on the next day after operation) and parenteral nutrition (PN) group (50％ glucose 100 ml intravenously infused on the next day after operation).Blood glucose and plasma GLP-1 were determined before operation,after operation,and 0 min,30 min,90 min,and 180 min after the 50％ glucose was used.Then,the EN group was divided into stress hyperglycemia (SH) subgroup and non-stress hyperglycemia (non-SH) subgroup.In both subgroups,plasma tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before operation,after operation,and the next day after operation.Blood glucose,plasma insulin,C-peptide,and GLP-1 were measured before operation,after operation,and 0 min,30 min,90 min,and 180 min after 50％ glucose was used.Results The plasma GLP-1 level (pmol/L) of EN group increased significantly after 50％ glucose was used,and reached the peak at the time of 30 min.In contrast,it did not change in PN group,and were significantly lower than EN group at the time of 30 min [(5.69 ± 2.92) pmol/L vs (33.52 ± 12.32) pmol/L,P ＜0.01] and 90 min [(5.71 ±2.14) pmol/L vs (15.92 ±6.63) pmol/L,P =0.00].Plasma insulin level in SH subgroup were significantly higher than in non-SH group after operation [(18.17±6.18) mU/Lvs (12.10±3.60) mU/L,P=0.01] and30 min [(56.02±14.78) mU/Lvs (43.39±15.60) mU/L,P=0.03] and 90min [(114.58±25.11) mU/Lvs (90.45±25.91) mU/L,P=0.03] after 50％ glucose was used.Plasma C-peptide level in SH subgroup was also significantly higher at the time of 30min [(6.86 ±1.15) μg/L vs (4.76 ± 1.06) μg/L,P=0.04] and 90 min[(12.17 ± 1.96) μg/L vs (9.81 ± 2.35) μg/L,P =0.03] after 50％ glucose was used when compared with non-SH subgroup.Plasma GLP-1 level in SH subgroup was significantly lower than in non-SH group at the time of 30 min [28.76 ± 9.61) pmol/L vs (37.36 ± 10.51) pmol/L,P =0.03] and 90 min [(13.49±4.26) pmol/Lvs (17.33±5.57) pmoL/L,P=0.04] after 50％ glucose was used.Conclusions Early post-operative PN increases plasma GLP-1 level and reduces the SH incidence.In SH patients,endogenous insulin expression increases while plasma GLP-1 level decreases.Post-surgery inflammatory reaction may result in low plasma GLP-1 level and high blood glucose level.
