OBJECTIVETo investigate the effect of early high-loading-dose tirofiban on platelet activity for patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention.

METHODSA total of 120 acute STEMI patients were treated with 300 mg aspirin and 600 mg loading dose clopidogrel and randomized to high-dose tirofiban (25 µg/kg bolus followed by 0.15 µg×kg(-1)×min(-1) infusion for 36 hours, n = 40), standard-dose tirofiban (10 µg/kg bolus followed by 0.15 µg×kg(-1)×min(-1) infusion for 36 hours, n = 40) or control (no tirofiban, n = 40) before angiography. Inhibition of platelet aggregation (IPA) was assessed before angiography, at 10 min and 24 hours after tirofiban infusion, and at 12 and 24 hours after stopping tirofiban infusion by the thrombelastography assay.

RESULTSThere was no significant difference in baseline of IPA between the 3 groups (P > 0.05). IPA was significantly higher in high-dose tirofiban group compared with standard-dose tirofiban and no tirofiban group at 10 minutes after tirofiban infusion [(84.2 ± 12.0)% vs. (67.8 ± 26.8)% and (31.5 ± 21.9)%, all P < 0.01]. At 24 hours after tirofiban infusion, the IPA of high-dose and standard-dose tirofiban was similar [(93.0 ± 9.8)% vs. (88.5 ± 18.1)%, P > 0.05] and was significantly higher than no tirofiban group [(40.4 ± 22.8)%, all P < 0.01]. IPA was similar at 12 and 24 hours after stopping tirofiban use among the 3 groups (all P > 0.05). The maximum amplitude of high-dose tirofiban and standard-dose tirofiban groups at different time points was similar (all P > 0.05), and maximum amplitude in both tirofiban groups was significantly lower than in no tirofiban group at 10 min [(47.2 ± 7.6) mm and (50.0 ± 9.8) mm vs. (57.7 ± 6.5) mm, all P < 0.01] and at 24 hours after stopping tirofiban infusion [(54.6 ± 5.6) mm and (54.3 ± 9.0) mm vs. (59.6 ± 4.0) mm, all P < 0.01].

CONCLUSIONEarly use of high-loading-dose of tirofiban on top of 600 mg loading dose clopidogrel is more efficient on inhibiting platelet activity than standard dose of tirofiban in patients with acute STEMI undergoing primary primary percutaneous coronary intervention.

Objective To investigate the diagnostic value of MRI in the infantile developmental dislocation of the hip.Methods Forty-five cases of preoperative hip MRI data of DDH (patient group)and 40 cases of normal hip (control group)MRI data were retrospectively analyzed.Three types were classified according to the standard of Dunn.Then the bony acetabular index (BAI),cartilaginous acetabular index (CAI)were measured on coronal MRI and all the intra-articular structures (articular cartilage,labrum, teres ligament and iliopsoas)in the acetabulum that impeded the reduction of the femoral head were observed.Results There were normal hips (80 hips)and dislocated hips (73 hips).In dislocated hips typeⅠ (30 hips),typeⅡ (20 hips),and typeⅢ (23 hips) were found.The values of BAI were (26.13±2.19)°and (35.87±4.42)°,CAI (13.84±1.07)°and (21.92±4.70)°for patient group and control group.The values of BAI were (31.80±1.74)°,(37.80±3.40)°and (39.17±4.11)°,CAI (17.20±2.68)°,(20.91±2.02)°and (27.50±2.78)°for the typesⅠ,Ⅱ,Ⅲ respectively.Differences of BAI and CAI between patient group and control group were showed (t=-11.048 and -9.188,P =0.000).Statistically significants were found among the typeⅠ,Ⅱ,Ⅲ(F=22.159 and 47.241,P =0.000).There were linear correlations for patient group ,control group,and the typeⅠ,Ⅱ,Ⅲ (r= 0.964,0.844,0.953,0.931 and 0.870,P =0.000).Some pathological changes such as varus labrum,thick teres ligament,iliopsoas spasm,articular cartilage hyperplasia,fat hyperplasia,joint effusion were observed in the type Ⅱand Ⅲ.Conclusion MRI is not only used for measuring the values of BAI and CAI,and a linear correlation among all kinds of DDH,but also some factors hindering the reduction of the femoral head can be found clearly.It can provide an important reference basis for the diagnosis and treatment of DDH.

Objective:To investigate the correlation of Mena protein expression with the invasion and metastasis of Mena SNPs with genetic susceptibility in gastric cancers (GC). Methods:A tissue microarray that simulates the invasion and metastasis process of GC was created, and immunohistochemistry was performed to detect the expression of Mena protein. The Mena gene 5 SNP loci geno-types of 188 healthy people and 389 GC patients were assayed using PCR-based LDR analysis. Results:The expression of Mena pro-tein in GC was significantly upregulated and greatly increased in the intestinal-type and mixed-type GC than that in the diffuse-type and was negatively related to the invasion and metastasis of GC. Patients with Mena overexpression had better prognosis. The frequen-cies of the A and G alleles, as well as the AA, AG, and GG genotypes, at the Mena SNP rs3795443 locus were significantly different be-tween patients with gastric carcinoma and the control groups (OR=2.1489,95%CI 1.4607~3.1613, P<0.01). The frequencies of these five Mena gene SNP loci were not significantly related with the survival of patients with gastric carcinoma. Conclusion:The upregula-tion of Mena expression is involved in maintaining the histological phenotype, invasion, metastasis, and prognosis of gastric adenocarci-noma. Individuals with GG and AG genotypes at the Mena rs3795443 locus have increased risk of gastric carcinoma, which suggests that screening for this genotype would be helpful in assessing the genetic susceptibility of gastric carcinoma.

Objective To evaluate the feasibility,security and efficiency of general anaesthesia compared with regional anaesthesia for minimally-invasive thyroid surgery(MITS)with short-stay discharge.Methods 103 cases undergoing MITS with short-stay discharge from Jan.2013 to Jun.2013 in Fuzhou General Hospital were collected.54 patients were operated under regional anaesthesia and 49 under general anaesthesia.All variables of patients including demographic characteristics,vital signs (blood pressure,heart rate,blood glucose) during the operation,duration and type of operation,postoperative complications,difficulty in airway management and anesthesia consumption were recorded and analyzed.Results There was no difference in respect to level of blood glucose,length of hospital stay,discharge time,patient or operator satisfaction rate,anesthesia or operation complications rate between the two groups.Blood pressure (T1:(90 ± 7.0) vs (79 ± 8.3) mmHg,T2:(88 ± 6.8) vs (80 ±7.6) mmHg,P ＜0.05) and heart rate(T1:(130 ± 18.2) vs(101 ± 12.0)/min,T2:(120 ± 19.7) vs(103 ± 13.3)/min,P ＜ 0.05)level were higher,while the recovery time of anesthesia((0.3 ± 0.14)vs(0.8 ± 0.35)h,P ＜ 0.05)) and anesthesia consumption ((1350 ± 78) vs (2580 ± 220) yuan,P ＜ 0.05)) were lower in the regional anaesthesia group compared with those in the general anaesthesia group.Conclusions Both general anaesthesia and regional anaesthesia for MITS with short-stay discharge are safe and effective.General anesthesia has less psychological trauma,while regional anaesthesia has shorter recovery time and lower anesthetic consumption.

AIM: To investigate the affected proteins by tumor necrosis factor (TNF)-? in endothelial cells, and further explore the potential molecular mechanism of TNF-? on endothelial cells. METHODS: Nitric oxide (NO) production in the cultured human umbilical vein endothelial cells (HUVECs) was measured by a NO assay kit. Proteomic alterations were analyzed using two-dimensional electrophoresis, and peptide mass fingerprinting with matrix-assisted laser desorption/ionization-time of flight mass spectrometry. RESULTS: NO production in HUVECs decreased significantly after TNF-? treatement. Proteomics analysis showed 21 protein spots were changed including 9 spots that were increased and 11 spots that were decreased after TNF-? stimulation, and 1 spot was only detected in TNF-? activated cell gels. CONCLUSIONS: The decreased expression of ecNOS by TNF-? might result in decrease in NO production. Up-regulated MAP/ERK kinase 3 expression might imply that TNF-? activates the expression of adhesion molecules. Cytoskeletal protein actin is also involved in TNF-? injuried HUVECs. Proteomic analysis can find some clues for identifying new potential target of TNF-?. [

OBJECTIVETo observe the effect of transcutaneous acupoint electrical stimulation (TAES) on brain tissue oxygen and glucose metabolism of the brain tissue in peri-operative period of the craniocerebral operation.

METHODSFifty patients scheduled for neuro-surgery were randomly assigned to the treatment group and the control group equally. Anesthesia applied after induction on all patients was continuous sevoflurane inhalation and intermittent intravenous injection of sulfenany and vecurnium bromide, but to the treatment group TASE was applied additionally from 30 min before anesthesia to the end of operation. Blood samples were taken from artery and jugular venous bulb at different time points, i. e. before induction (T0) , before skin incision (T1) , at the end of operation (T2) , and 10 min after extubation (T3) , for blood-gas analysis. The difference of oxygen, glucose and lactate contents between blood samples of arterial and jugular bulb (Da-jvO2, Da-jvGlu and Da-jvLac) at respective time point were determined and calculated.

RESULTSDa-jvO2 decreased in both group at T1, T2 and T3, and all lower than that at T0 (P < 0.05 or P < 0.01), but significant difference was shown in comparison of the index at T2 and T3 with the same time points in the control group in the treatment group (P < 0.05 or P < 0.01) , and that between groups at T2 and T3 (P < 0.01). Da-jvGlu in the treatment group decreased at T2 and T3 (P < 0.05), but keep unchanged relatively in the control group before and after anesthesia, inter-group comparison showed it was lower at T2 and T3 in the treatment group than that in the control group respectively (P < 0.05). Da-jvGlu in the treatment group at T1, T2, and T3 were all lower than that at the same time points (P < 0. 01).

CONCLUSIONTAES can significantly decrease the oxygen and glucose metabolism of the brain tissue in the perioperative period of the craniocerebral operation.

To investigate the influence of the difference enhancers on the transport mechanism of chlorogenic acid (CGA) across Caco-2 cells model, a RP-HPLC method was adopted to detect the concentrations of CGA. At the concentrations of 20 to 80 microg x mL(-1), the difference of absorption rate constants (K(a)) was not statistically significant. At the concentrations of 40 and 20 microg x mL(-1), the ratios of apparent permeability coefficients (P(app)) of the apical to basolateral and the basolateral to apical were 1.14 and 1.18, respectively. With the effect of enhancers K(a) and P(app) increased, the absorption half-life (T1/2) decreased. CGA passed through the Caco-2 cell membrane mainly by passive transport. It showed that monocarboxylic acid transporter (MCT) could be involved in the across membrane transport process of CGA. Borneol had no effect on the cell membrane transport processes. The order of increasing absorption of CGA caused by the enhancers was sodium lauryl sulphate > sodium taurocholate > carbomer.
