Objective To investigate the etiology,diagnosis and treatment of the delayed gastric emptying after abdominal surgery.Methods From January 2005 to December 2012,the clinical data on diagnosis and treatment of 32 cases of delayed gastric emptying after abdominal surgery were retrospectively analyzed.Results Delayed gastric emptying occurred in 32 cases after 5-8 days after the surgery,which accounted for 40.63％ of gastric surgery.Blood loss was 100-300 mL in 15 cases,9 cases' blood loss was more than 350 mL,accounting for 75％.Thirty cases were cured by conservative treatment,accounting for 93.75％,2 cases on the 20th day after surgery and the 31 th day after surgery to accepted surgery again,accounting for 6.25％.Conclusion The delayed gastric emptying after surgery is closely related to surgical site,methods and surgical sub-injury.Non-occurrence of surgical treatment is the main method to cure this disease.

Objective To investigate the value of emergency bedside focused assessment with sonography for trauma (FAST) in combination with regional organ focused ultrasonography in patients with closed abdominal trauma.Methods Two hundred and thirty-seven patients with closed abdominal trauma underwent bedside ultrasonography in the Emergency Department at General Hospital of Chengdu Military Command.In patients with unstable hemodynamics or severe craniocerebral injury,ultrasonography was ended immediately after FAST screening.In patients with stable vital signs,the focused regional organ injury after FAST screening was determined based on the mechanism of trauma,action location and direction of external force,abdominal symptoms,and signs.The results of operation and CT scanning were considered as golden criteria and used to compare with those of ultrasonography.Results (1) The diagnostic sensitivity of FAST to abdominal organ rupture and ascites due to abdominal organ rupture calling for emergency operation was 79.3％ and 100％,respectively.The total specificity of FAST was 98.2％,positive predictive value 93.9％,and negative predictive value 86.7％.(2) The diagnostic accordance rate of single visceral injury examined by regional organ focused ultrasonography was 91.2％ and that of multiple visceral injury was 63.6％.The missed diagnoses were predominantly contusion and microlaceration.Conclusions FAST can quickly screen out the patients with unstable hemodynamics due to abdominal organ rupture calling for emergency management.Regional organ focused ultrasonography can increase the rate of correct diagnosis of visceral injury and decrease the rate of missed diagnosis.

To establish a LC-MS/MS method for quantification of chlorogenic acid, caffeic acid, 3,4-DCQA, ferulic acid and cinnamic acid in rats plasma and study its pharmacokinetics after administration of Mailuoning injection at a single dose to rats. Plasma samples were acidified with hydrochloric acid and extracted with ethyl acetate. The analytes were determined by LC-MS-MS using a ZOBAX SB C18 column with a mobile phase of methanol-water (containing 2 mmol x L(-1) ammonium acetic) (60:40)at a flow rate of 0.5 mL x min(-1) and detected using ESI with negative ionization mode. Ions monitored in the multiple reaction monitoring (MRM) mode were m/z 353.1/191.0 [M-H]- for chlorogenic acid, m/z 178.9/134.9 [M-H]- for caffeic acid, m/z 515.2/353.0 [M-H]-for 3,4-DCQA, m/z 193.0/133.9 [M-H]-for ferulic acid, m/z 146.9/102.9 [M-H]- for cinnamic acid and m/z 246.0/125.8 [M-H]- for tinidazole (IS). After administration of Mailuoning injection at a single dose to eight Sprague-Dawley rats, the concentrations of chlorogenic acid, caffeic acid, 3,4-DCQA, ferulic acid and cinnamic acid in plasma were determined by LC-MS/MS method. The main pharmacokinetics parameters of measured data were caluculated by using DASver 1.0 software. The linear concentration ranges of the calibration curves for chlorogenic acid, caffeic acid, 3,4-DCQA and cinnamic acid were 2.006-1,027 microg x L(-1) (r = 0.999 6), 1.953-1,000 microg x L(-1) (r = 0.999 7), 28.51-1.459 x 10(4) microg x L(-1) (r = 0.998 9), 1.836-940.0, g x L(-1) (r = 0.997 7) and 4.780-2,447 microg x L(-1) (r = 0.998 6) respectively. The inner and inter-days relative standard deviations were both less than 5.0%, indicating legitimate precise and accuracy to the requirement of biological sample analysis. For chlorogenic acid, the pharmacokinetic parameter t1/2, AUC0-t, and CL were (49.78 +/- 12.81) min, (123.55 +/- 14.82) mg x min x L(-1) and (0.004 3 +/- 0.000 5) L x min(-1), respectively. For caffeic acid, the pharmacokinetic parameter t1/2, AUC0-t, and CL were (36.65 +/- 10.59) min, (91.67 +/- 11.77) mg x min L(-1) and (0.005 7 +/- 0.000 7) L x min(-1), respectively. For 3,4-DCQA, the pharmacokinetic parameter t1/2, AUC0-t, and CL were (50.08 +/- 13.78) min, (278.34 +/- 31.82) mg x min x L-1 and (0.001 6 +/- 0.000 2) L x min(-1), respectively. For ferulic acid, the pharmacokinetic parameter t1/2, AUC0-t, and CL were (51.39 +/- 15.52) min, (34.72 +/- 4.67) mg x min x L(-1) and (0.000 4 +/- 0.0001) L x min(-1), respectively. For cinnamic acid, the pharmacokinetic parameter t1/2, AUCo-t, and CL were (74.42 +/- 18.32) min, (34.63 +/- 4.82) mg x min x L(-1) and (0.007 7 +/- 0.001 1) L x min-', respectively. The assay method is proved to be sensitive, accurate and convenient. It can be applied to the pharmacokinetic study of chlorogenic acid, caffeic acid, 3,4-DCQA, ferulic acid and cinnamic acid.

OBJECTIVETo study the effects of Jisuikang (Chinese characters) on Nogo-NgR gene expression, and to explore the protective effects and mechanism of Jisuikang (Chinese characters) on spinal cord injury in rats.

METHODSOne hundred eighty female rats were randomly assigned to 6 groups(30 rats per group). Sham group: T10 lamina was resected only and spinal cord was untreated. Model group: spine cord injury (SCI) was created with a modified impinger of Allen's by impacting on the T10 spinal cord. Prednisolone group: Prednisolone (0.06 g/kg) was given by intragastric administration at a time interval of 24 hours after operation. The Jisuikang (Chinese characters) high, moderate and low dose groups: Jisuikang (Chinese characters) was supplied with different dose (50 g/kg, 25 g/kg, 12.5 g/kg) by intragastric administration in rats after operation,for the first time at 30 min after surgery. Animals were killed 3, 7, 14 days after surgery. The expression levels of Nogo-A and NgR were observed by Western Blot and Real-time PCR.

RESULTSThe expression of Nogo-A and NgR was at the basic level at all time points in sham group. Compared with model group, the protein expression levels of Nogo-A and NgR in sham, prednisolone, Jisuikang (Chinese characters) moderate dose groups were statistically significant at all time points (P < 0.05). No difference was found in Jisuikang (Chinese characters) high and low dose groups (P > 0.05). Three days after surgery, the mRNA levels of Nogo-A and NgR in treatment group were significantly lower than that in model group (P < 0.01); 7 days after surgery,Nogo-A and NgR mRNA expression were dramatically upregulated and peaked; 14 days after operation, the expression was decreased, but still significantly higher than that in other treatment groups (P < 0.01). Prednisolone and Jisuikang (Chinese characters) moderate dose groups showed the most significant effects among all groups,but there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONThe decoction Jisuikang (Chinese characters) can promote the nerve cell regeneration by regulating Nogo-A and NgR gene expression, activating Nogo- NgR signaling pathways after acute spinal cord injury.
