Objective To observe the application value of cardiac troponin I (cTnI),cardiac troponin T (cTnT) and creatine kinase MB (CK MB) for the early diagnosis of acute myocardial infarction (AMI).Methods The same serum sample was measured to detect the indexes of cTnI,cTnT and CK MB levels in 60 patients with AMI and 40 patients with UA.Comparison between AMI and UA was performed and all the indexes were analysed contrastively.Results The sensitivity of cTnI and cTnT was higher than that of CK MB,and their positive rates were 63.3%,46.7% and 18.3% respectively (P0.05) and the specificity of the three indexes were almost the same without significant difference.Conclusion cTnI and cTnT,as specific markers of cardiac damage,are more sensitive and specific in the early diagnosis of AMI.As a convenient,swift and accurate measurement method,cTnI has significant clinical value.

Objective To study the effect of gastrin, motilin of chronic atrophic gastritis model in rats by acupuncturing at back-shu points. Methods 60 SD rats were randomly divided into blank control group, model control group, omeprazole group, back-shu points group, with 15 rats in each group, and to establish the model of chronic atrophic gastritis by irregular diet that given rats odd and even days. The blank control group, model control group were fed with normal saline, 2ml/time, 1 time/day. The omeprazole group was given oral gavage(Omeprazole 0.44 mg/kg, Clarithromycin 6.92 mg/kg, Metronidazole 7.6 mg/kg), 1 time/day. Back-shu points group received acupuncture at “Geshu”“Ganshu”“Pishu”“Weishu”“Shenshu”, retaining 15 min, 1 time/day. After 30 days, the content of ELSIA was used to detect the serum gastrin, motilin. Results ①GAS of model control group(54.25±5.70)pg/ml was significantly decreased compared with blank control group(66.63± 5.99)pg/ml, the difference was statistically significant (P<0.05). Compared with the model control group, GAS content of omeprazole group(62.70±8.55)pg/ml and back-shu Points group(66.27±3.79)pg/ml were higher, showed significant differences(P<0.05). ②MOT of model control group(223.60±17.83)pg/ml was significantly increased compared with the blank control group(188.45 ± 8.90)pg/ml, the difference was statistically significant(P<0.05). MOT of omeprazole group(200.16 ± 4.38)pg/ml and back-shu Points group(190.11±10.04)pg/ml were lower than those in the model control group, there was statistically significant difference(P<0.05). Conclusion Acupuncturing at back-shu acupoints can increase the content of GAS, reduce content of MOT, regulate gastrointestinal hormone in rats of chronic atrophic gastritis model.

Objective To analyze the clinical effect of brevisapine injection on high sensitivity C-reaction protein level in the treatment of acute myocardial infarction.Methods The patients were randomly divided into treatment group(n=80)and control group(n=80).Both groups were treated with routine midication,but treatment group were given intravenous drip of 100 mg brevisapine once a day.for 14 days.80 paients who came for diagnosis were selected for healthy control group.The selqlm high sensitivity C-reaction protein levels were measured at 2 d,7 d,and 14 d by ELLSA in treatment group,control group and healthy control group.Mortality,heart function status (Killip class),revaseularization and clinical adverse cardic events including postinfartion angina,new arrhythmia,reinfarction and bleeding complication at 4 weeks were observed.Results Treatment group had a significantly high level of hs-CRP compared with healthy subjects[(6.37±1.43)vs.(2.17±1.12)mmol/L,P＜0.01]at the second day.The serum hs-CRP content of treatment group was obviously lower than that of control group(3.21±1.31)and(2.25±0.34)mmol/L vs.(5.87±1.16)、(3.97±1.21)mmol/L,(P＜0.01)]on the 7th,14th days;The revascularization rate of treatment group was obviously higher than that of control group[62.50%(50/80)vs.51.25% (45/80),P ＜0.01];There was no difference between the two groups in mortality(3.75% vs.4.10%,P ＞0.05).No difference was found in the rate of bleeding between the two groups(6.25% vs.7.50%,P ＞0.05);Patients with Killip class＜Ⅱ of treatment group was obviously higher than that of control group (83.75% vs 61.25%,P ＜ 0.05 );Clinical adverse cardic events rates at 4 weeks of treatment group were obviously lower than those of control group (P ＜ 0.01 ).No obvious adverse reactions related to the treatment group were observed.Condusion The serum hs-CRP level is in close relation with acute myocardial infarction,which is the risk factor.It is effective and safe of brevisapine injection in the treatment of acute myocardial infarction.The effects of brevisapine on acute myocardial infarction might be involved in decreasing the level of hs-CRP and inhibiting the vascular inflammatory reaction.

Objective To investigate the effects of inhalation of different concentrations of sevoflurane on pulmonary inflammatory response in rats. Methods One hundred and twenty adult Wistar rats of both sexes weighing 200-250 g were randomly divided into 4 groups: Ⅰ control group breathing room air (group C, n = 12);Ⅱ oxygen group breathing 40% O2(group O, n = 36);Ⅲ and Ⅳ sevoflurane groups breathing 1.5% and 3.0% sevoflurane in 40% O2 respectively (group S1, S2, n = 36). Group Ⅱ was further divided into 3 subgroups according to the duration of 40% O2 inhalation 4 h, 8 h and 10 h. Group Ⅲ and Ⅳ were further divided into 3 subgroups ( n = 12 each) breathing sevoflurane for 4 h, 8 h and 8 h followed by 2 h O2 (40%) inhalation. The animals were sacrificed at the end of O2 or/and sevoflurane inhalation. Broncho-alveolar lavage was performed in 6 animals in each subgroup. The TNF-α concentration in broncho-alveolar lavage fluid was determined. The TNF-α mRNA expression and MPO activity in the lung tissue were measured in the other 6 animals in each subgroup. Results Inhalation of 1.5% or 3.0% sevoflurane for 4 or 8 h did not induce inflammatory response in the lung as compared with animals breathing room air or 40% O2 . Conclusion Exposure to sevoflurane does not induce pulmonary inflammatory response in rats breathing spontaneously.

Objective To investigate the relationship of polymorphisms at codons 333 and 637 of TAP-1 allele gene to recurrent condyloma acuminatum (CA) in a Chinese population. Methods Amplificatory refraction mutation system-PCR (ARMS-PCR) was performed to detect TAP1 polymorphic residues at codon 333 in 88 patients with recurrent CA and 81 age- and sampling date-matched controls and at codon 637 in 60 patients with recurrent CA and 60 age- and sampling date-matched controls. Results The frequencies of AA,GG and AG genotypes at codon 333 of TAP-1 gene were 86.36%, 0, 13.64%, respectively, in patients with recurrent CA, 79.01%, 0 and 20.99%, respectively, in the controls, and no significant difference was observed between the two groups (χ2 = 1.604, P ＞ 0.05). However, a significant difference was observed in the frequencies of AA, GG and AG genotypes at codon 637 of TAP-1 gene between the patients and controls (3.33% vs 10.0%, 95.00% vs 60.00%, 1.67% vs 30.00%, χ2 = 21.551, P ＜ 0.01 ). Conclusions The recurrence of CA may be associated with the polymorphism at codon 637, but not with that at codon 333, of TAP-1 gene.

Objective To assess the efficacy of laryngeal mask airway Supreme (LMA Supreme) used in patients undergoing laparoscopic surgery. Methods One hundred and twenty ASA I or Ⅱ patients of both sexes aged 35-60 yr weighing 48-85 kg undergoing elective laparoscopic surgery were randomized to 2 groups ( n = 60 each): LMA Supreme group (group S) and tracheal intubation group (group T). Mallampati test was performed before operation in both groups. The patients were classified as I - Ⅲ . In group S the LMA Supreme was inserted after induction of anesthesia with sufentanil 0.2 fig/kg, propofol 2-3 mg/kg and vecuronium 0.1 mg/kg. A gastric tube was inserted through the drain tube of the LMA Supreme. In group T the patients were intubated under direct laryngoscopy. The success rate, LMA placement/intubation time, success rate of gastric tube placement, airway seal pressure, SpO2, PETCO2 , peak airway pressure and complications (hypoxemia, nausea and vomiting, choking hoarseness, sore throat and regurgitation of gastric contents) were recorded. The duration of surgery, anesthesia time, extubation time and emergence time were also recorded. Results There was no significant difference in the success rate between the two groups. The placement and removal time and recovery time were significantly shorter in group S than in group T. The airway seal pressure was (25 ±4) cm H2O in group S. SpO2, PETCO2 and peak pressure were within normal range in both groups. The incidence of postoperative hypoxemia, choking and sore throat were significantly lower in group S than in group T. Conclusion LMA Supreme can provide adequate ventilation during operation with less complications and can be used effectively for laparoscopic surgery.

ObjectiveTo investigate the relationship between the polymorphisms of the promoter of a disintegrin and metalloproteinase 10(ADAM10) gene and sporadic Alzheimer's disease (SAD).Methods The promoter of ADAM10 gene in 10 controls and 10 SAD patients was sequenced.Three variations were found,then these variations in 298 SAD patients (SAD group) and 315 healthy controls (control group)were genotyped by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).ResultsThree polymorphisms were found in the promoter of ADAM10 gene: -279G/A (rs653765),- 630G/T( rs514049 ) and - 921GAGA/- ( rs33926666 ).For - 921GAGA/-,there were significant differences in genotype ( GAGA/GAGA:138 (46.3％ ),GAGA/-:155(52.0％),-/-:5(1.7％))and allele frequencies (GAGA:431 (73.6％),-:165 (27.7％) ) between SAD and control (genotype:x2 =34.130,P =0.000; allele:x2 =25.972,P =0.000). For - 279G/A,there were significant differences in genotype and allele frequencies between SAD and control in the subjects without ApoEε4 allele (genotype:x2 =8.734,P=0.013; allele:x2 =5.129,P=0.024). -279G and -921GAGA were relatively protective allele types for SAD,and they were not in linkage disequilibrium.ConclusionThe polymorphisms - 279G/A and - 921GAGA/- of ADAM10 are associated with SAD.Allele G or genotype G/G of -279G/A and the GAGA/GAGA genotype or the GAGA allele of -921GAGA/- might have a protective effect on SAD.

Objective To evaluate the effect of neuromuscular block on the airway sealing pressure of laryngeal mask airway (LMA) i-gel in patients undergoing general anesthesia.Methods Sixty patients scheduled for elective surgery under general anesthesia with LMA i-gel were randomly allocated to one of three groups (n =20 each):control group (group C),rocuronium 0.3 mg/kg group (group R1) and rocuronium 0.6 mg/kg group (group R2).Anesthesia was induced with target-controlled infusion of propofol and remifentanil.The target plasma concentration of propofol was 3.5 μg/ml,and the target effect-site concentration of remifentanil was 3.0 ng/ml.When the patients lost consciousness and after the target plasma and effect-site concentrations were balanced,LMA i-gel was inserted to perform mechanical ventilation.After insertion of LMA i-gel,rocuronium 0.3 and 0.6 mg/kg were injected in R1 and R2 groups,respectively.The airway sealing pressure of LMA i-gel was detected immediately after insertion of LMA i-gel and at 1 min after administration of rocuronium.Results There was no significant difference in the airway sealing pressure of LMA i-gel between groups and within groups(P ＞ 0.05).Conclusion Neuromuscular block has no significant effect on the airway sealing pressure of LMA i-gel in patients undergoing general anesthesia.

OBJECTIVETo establish a general method of focal cerebral ischemia model in different varieties of mice.

METHODEach group of healthy adult KM and C57BL/6 mice were randomly divided into control group (n = 10) and MCAO group (n = 10). The mice in MCAO group were applied in the preparation of the MCAO model by intraluminal occlusion using monofilament. Twenty-four hours after operation,the neurologic function was evaluated,middle cerebral artery blood flow was monitored and the infarction volume was calculated by TTC staining, to evaluate the reliability of the model.

RESULTIn the MCAO group, the base value of the cerebral blood flow down of KM and C57BL/6 mice respectively was (81.65 ± 4.59)%, (83.68 ± 6.25)%. The neurological deficit score respectively was (2.30 ± 0.82), (2.50 ± 0.80). TTC staining can clearly show the infarction area, and relatively stable, 24 hours of the survival rate of KM and C57BL/6 mice were 100% and 80% respectively.

CONCLUSIONThe key link is the optimization and improvement of monofilament, temperature, anesthesia and so on. The modified intraluminal occlusion of MCAO using monofilament is a kind of reliable and simple method to establish experimental cerebral ischemia model in mice.
