ObjectiveTo observe the effects of XinShu parenteral solution (XSPS) on the activation of platelet, the activity of fibrinolysis system after intima denudation of rabbits.Methods20 male Japanese white rabbits (2.5±0.5)kg were randomly divided into the control group and XSPS group .The celiac arterial endothelium of all rabbits were denuded with balloon. Before the operation and 3d, 7d, after balloon denudation, vein blood samples were obtained from each group rabbits for measurement of α granule membrane protein of platelets(GMP-140), tissue-type plasminogen activator(t-PA) and plasminogen activator inhibitor-type Ⅰ(PAI-1).ResultsPlasma GMP-140 and PAI-1 activity obviously elevated after balloon injury, and there was a little elevation in plasma t-PA activity in control group. Activity of plasma GMP-140 in XSPS group remained bottom level after balloon injury, and there was a significant increase in plasma t-PA activity and a marked reduce in PAI-1 activity in XSPS group. There was a notable difference between group B and group C (P<0.05). ConclusionXSPS obviously inhibits platelet activation, and improves fibrinolysis activity after balloon injury.

Objective: To access the risk for smoking on morbidity of acute ST-segment elevation myocardial infarction (STEMI) at different gender and age population. Methods: A case-control study was conducted in 2026 STEMI patients and 2026 control subjects with matched gender and age (±2 years) in our hospital from 2010-01-14 to 2016-02-27. The relationship between smoking and STEMI morbidity was analyzed. Results: Smoking was an important risk factor for STEMI morbidity in male gender and it was negatively related to age, as STEMI in young male smokers (≤45 years): adjusted OR=7.000, 95% CI 4.235-11.570; in middle age male smokers (46-59 years):adjusted OR=5.296, 95% CI 3.904-7.185 and in elder male smokers (≥60 years): adjusted OR=4.686, 95% CI 2.860-4.751. Conclusion: Smoking is a major risk factor for STEMI morbidity, while it is different from age and gender; the young male smokers have the highest risk to suffer from STEMI.

Objective To study the impact of enteral nutrition (EN) or parenteral nutrition (PN) in postoperative colorectal cancer patients on viscera organ function and "passing wind" time.Methods Totally 30 patients with colorectal cancer joined this study with informed consent.Patients were randomly divided into EN group and PN group.Both two groups were given nutritional support from the first post-operative day to the 7th post-operative day.The pre-operative and post-operative viscera organ functions and the recovery time of gastrointestinal functions are observed.Results Total bilirubin was significantly lower in EN group than in PN group (P ＜ 0.05).The length of post-operative hospital stay was significantly shorter in EN group than in PN group (P ＜0.01).The post-operative complications were not significantly different between two groups (P ＞ 0.05).Conclusion Postoperative EN support is beneficial for colorectal cancer patient in terms of lower bilirubin levels,shorter post-operative hospital stay,and lower cost.

Objective To analyze the resistance genes in a muhidrug resistant Klebsiella pneumoniae (MDRKP) strain.Methods A MDRKP strain was isolated from bronchoalveolar lavage fluid in Pediatric Intensive Care Unit of Children's Hospital Affiliated to Soochow University in February 2012.Acquired resistance genes to beta-lactams,aminoglycosides,quinolones,ompK35 and ompK36 gene for outer membrane porin protein,and carbapenems targeting PBP2 gene were analyzed by PCR and verified by DNA sequencing.Results Acquired resistance genes TEM-1,SHV-1 to beta-lactam antimicrobial agents and aac(6′)-I b to aminoglycoside antimicrobial agents were positive in the strain of MDRKP.While 16S rRNA methylase,ompK35 and ompK36 genes for outer membrane porin protein were negative.Compared with susceptible strains,there were 9 synonymous mutations in PBP2 gene sequence of this MDRKP strain,but the amino acid sequences were the same.No mutation in quinolone resistance determining region (QRDR) was observed.Conclusion The multidrug resistance of the isolated Klebsiella pneumoniae strain may be related to 2 kinds of beta-lactam acquired resistance genes,1 kind of aminoglycoside acquired resistance gene,ompK35 and ompK36 genes defects and synonymous mutation in PBP2 gene.

Objective To explore the changes in cardiac index and oxygenation index in sepsis piglets after nitric oxide (NO) gas inhalation. Methods A piglet model of sepsis was induced by intravenous infusion of Gram-negative bacterial endotoxin (LPS), then the piglets were randomly divided into two groups. NO group (n=8) was administered with inhaled nitric oxide of 80ppm via volume control (VC) mechanical ventilation for one hour, while the control group (n = 4) received mechanical ventilation with VC and was observed for one hour to assess the stability of the model. The parameters of oxygenation and hemodynamics were measured by PICCO and arterial blood gas analysis every fifteen minutes for one hour. Results Injection of endotoxin induced a stable pig model of sepsis. PH, HCO3-, arterial oxygen pressure (PaO2), mean arterial pressure (MAP) and cardiac index in this model were significantly lower the baseline values (P < 0.01). Arterial oxygen pressure and cardiac index were significantly higher in N0 group than in the control group (P<0.01). Heart rate (HR), central venous pressure (CVP), global end-diastolic volume index (GEDI) and intrathoracic blood volume index (ITBI) did not significantly differ between NO group and the control group. Conclusions Inhalation of nitric oxide gas can significantly improve oxygenation and cardiac function in piglets with sepsis.

Objective To investigate the association of the rs 2118181 polymorphism of FBN-1 gene ( encoding Fibrillin-1 ) and the risk of acute aortic syndrome ( AAS ) in Chinese Han population. Methods Genomic DNA was extracted from the blood of 206 patients suffering AAS and 209 individual-matched controls.The dideoxy chain termination method was used to determine the genotypes of rs 2118181 single nucleotide polymorphisms .Results The TT frequency of rs 2118181 genotype was significantly higher in the patients with AAS , especially with Intramural Haematoma ( IMH ) than in the controls ( 62.1%, 70.4% vs.52.5%, P<0.05).Carriers of CT or CC genotype had a less risk for AAS , especially for IMH, compared with carriers of TT genotype.The odds ratio were 0.66 (95%CI:0.45-0.98, P=0.040) and 0.46 (95%CI:0.24-0.87, P=0.016) respectively.After adjusting for age, sex, body mass index, hypertension , body mass index , smoking , diabetes mellitus , the odds ratio for AAS was 0.66 ( 95% CI:0.44-0.99 , P=0.048 ) .However , there was no significant difference on the frequencies of rs 2118181 genotype between the two subgroups of classical aortic dissection and intramural haematoma . Conclusions The rs2118181 polymorphism of FBN-1 gene is correlated to the sporadic AAS , especially to IMH, in Chinese Han population .The carriers of TT genotype are vulnerable to AAS , especially to IMH , compared with the non-carriers.

[Summary] The aim of this study was to examine the association between obstructive sleep apnea-hypopnea syndrome ( OSAHS ) and microalbuminuria in type 2 diabetes mellitus patients. We found that severe OSAHS significantly increases the risk of early renal damage in type 2 diabetes mellitus patients with HbA1C<7% ( lowest oxygen saturation:OR=2. 41, 95% CI 1. 19-8. 08; apnea hyponea index: OR=2. 91, 95% CI 1. 50-9. 11), suggesting that OSAHS may increase the risk for early renal damage in type 2 diabetes mellitus, especially in those with successful control of glucose.
