Objective To explore the clinical significance of APACHE Ⅱ score on risk stratification in patients with acute myocardial infarction.Methods One hundred and forty-two patients with acute myocardial infarction were included in the study who were admitted to hospital consecutively from Jan.2011 to Dec.2012.High risk group and low risk group were divided by the APACHE Ⅱ score.Some clinical variables at the first 24 h after admitted to hospital and occurring during the following 1 year were recorded Results The age in high risk group was 78.9 ±8.1,significantly higher than that in low risk group (65.8 ± 10.2;t =6.835,P ＜ 0.001).The cases with Killip Ⅲ and Ⅳ in high risk group were 10(29.4％) and 2(1.8％),lower than in low risk group (6 (1.8％) and 0 (0％) ; x2 =21.950,15.777 ; P ＜ 0.005).The level of creatine kinase-MB (CK-MB) and cardiac troponin Ⅰ in high risk group were (147.7 ±21.5) U/L and (105.5 ± 17.6) U/L,higher than in low risk group((105.5 ± 17.6) U/L,(42.9 ± 6.3) U/L; t =11.541,5.785 ; P ＜ 0.001).The incidence of severe cardiac events(malignant arrhythmia,heart failure,non fatal myocardial infarction and death from any cause in high risk group were 58.8％ (20/34),47.0％ (16/34),17.6％ (6/34) and 17.6％ (6/34),higher than in low risk group (29.6％ (32/108),3.7％ (4/108),6.4％ (7/108) and 6.4％ (7/108) ; x2 =8.274,36.665,3.876 and 3.876 ; P ＜ 0.05).Conclusion APACHE Ⅱ score is likely to be a simple and practical tool for risk stratification in patients with acute myocardial infarction.

Objective To evaluate the effect of intrathecal resveratrol on activation of Ca2+/ calmodulin-dependent protein kinase Ⅱ (CaMK Ⅱ) in spinal dorsal horn neurons of rats with bone cancer pain.Methods Thirty-two adult female Sprague-Dawley rats,weighing 180-220 g,were equally randomized into 4 groups using a random number table:sham operation group (group S),bone cancer pain group (B group),and bone cancer pain + solvent control group (BD group).Walker 256 mammary gland cancer cell suspension (4× 105 cells/ml) 5 μl was injected into the medullary cavity of the right tibia in B,BR and BD groups.Normal saline 5 μl was given in group S.On 12,13 and 14 days after injection of mammary gland cancer cells,resveratrol 200 μg/10 μl was injected intrathecally once a day in group BR,and 1％ dimethyl sulfoxide 10 μl was intrathecally injected once a day in group BD.Before injection of mammary gland cancer cells (T0) and on 3,5,7,10,12 and 14 days after injection of mammary gland cancer cells (T1-6),mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured.The rats were then sacrificed and L4,5 segments of the spinal cord were removed for confirmation of the location of phosphorylated CaMK Ⅱ (p-CaMK Ⅱ) in spinal dorsal horn neurons (by immunofluorescence) and for detection of p-CaMK lⅡ expression (using Western blot).Results Compared with group S,MWT and TWL were significantly decreased at T2-6,and p-CaMK Ⅱ expression was upregulated at T6,and p-CaMK Ⅱ was mainly co-expressed with neurons in B,BR and BD groups.Compared with group B,MWT and TWL were significantly increased at T5,6,and p-CaMK Ⅱ expression was down-regulated at T6 in group BR.There was no significant difference in MWT,TWL,and p-CaMK Ⅱ expression at each time point between group B and group BD.Conclusion Resveratrol can alleviate hyperalgesia in rats with bone cancer pain and inhibited activation of CaMK Ⅱ in spinal dorsal horn neurons may be involved in the mechanism.

Objective To explore the complication and its cause and treatment of pace markers implantation in older patient.Methods Among 205 older patients aged 70 to 90 years,103 were male,the others were female.Of these patients,162 were implanted with single chamber pace marker,43 with dual chamber pace markers.Results 21 patients happened complication(10.2%),the common complications related to operation were blood effusion and hematoma formation in pocket 12 cases,lead dislodgement 4 cases and infection with or without pocket rapture 2 cases.Occurrence of blood effusion was related to aspirin administration,lead dislodgement and infection with or without pocket rapture were related to operation.Conclusion To pay attention to ample preparation,close operation and strict observation can decrease the complication rate when pace marker is implanted.The serious result will be avoided by timely and effective treatment.The older patient with pace markers implantation is safe.

Objective To investigate the polymorphism of Brucella melitensis biovar 3 ( B.melitensis biovar 3) strains isolated from Guangdong province .Methods PCR assays followed by agar-ose gel electrophoresis and capillary electrophoresis based on the multiple locus variable number of tandem repeats (VNTR) analysis (MLVA) were performed to analyze 43 clinic isolates of B.melitensis biovar 3 strains isolated from clinical patients in Guangdong province .Results MLVA typing showed that the simi-larities of the analyzed locus among 43 strains of Brucella ranged from 68.2%to 100%.32 genotypes identi-fied among the isolates were identical (100%similarity).27 out of 43 strains (62.8%) were single geno-types, while the other 16 strains (37.2%) belonged to 5 other genotypes with 2 to 5 strains in each of them . Conclusion B.melitensis biovar 3 isolates showed polymorphism distribution in Guangdong province as in-dicated by MLVA typing analysis .Single-genotype isolates accounted for 62.8% of all studied strains.No predominant genotype was found among all isolates .

Objective To determine the correlation between the risk factors of cerebral palsy and gestational age of live born infants. MethodsThe gestational age, the risk factors of cerebral palsy and clinical features of 478 children with cerebral palsy were analyzed retrospectively. ResultsFetal distress, threatened abortion, non-infectious diseases during pregnancy, hypoxic-ischemic encephalopathy, neonatal convulsion, infection of newborn, intracranial hemorrhage and haemolysis did not correlated with the gestational age of children with cerebral palsy (P>0.05). Brain malformation, maternal infection, aspiration pneumonia, neonatal asphyxia and hyperbilirubinemia negatively correlated with the gestational age (P<0.05). The incidence of spasmo-diplegia was significantly different between preterm and term infant (P<0.05). ConclusionThe morbidity of cerebral palsy associated with the merging development malformation, maternal infection, aspiration pneumonia, neonatal asphyxia or hyperbilirubinemia increased as the gestational age declined. The spasmo-diplegia more happened in the preterm infants than in the term ones.

One hundred and thirty seven pafients diagnosed by coronary angiography were recruited in the study and divided into coronary heart disease group(CAD)and control group.Relationship between serum apolipoprotein M levels and the severity of stenosis of coronary arteries was analyzed.In covariate analysis,serum apolipoprotein M levels were significantly lower in CAD group than those in control group adjusted for sex,age,body mass index(BMI)(P＜0.05).By stepwise muhiple regression,serum levels of apolipoprotein M were correlated positively with BMI(r=0.65,P＜0.01),and correlated negatively with total cholesterol(TC)(r=-0.53,P＜0.01)and low density lipoproteins(LDL-C)(r=-0.42,P＜0.01).Serum levels of apolipoprotein M were correlated negatively with the score of coronary stenosis(r=-0.62,P＜0.01).The results suggest that apolipoprotein M might be related to the development of coronary artery disease.

Objective To observe the changes of islet cell apoptosis and oxidation-antioxidation before the transplantation, and to explore the pathways of islet protection. Methods Fifteen human pancreases were perfused with the Hanks solution containing collagenase, then digested and isolated. During the procedure, islet cell apoptosis was detected by TUNEL, SOD and MDA in the pancreas were measured by colorimetric method, and the morphologic changes were observed by H-E staining and dithizone staining. Results In the procedure of human islet isolation, especially in the stage of digestion, the apoptosis of human islet cells occurred. In the stages of perfusion and digestion, the MDA contents reached the high levels (6. 18 ± 2. 38 and 9. 21 ± 2. 75 umol/mg protein respectively),and the structures of the islets and tissues around the islets were damaged. Conclusion In the stages of perfusion and digestion, apoptosis of islet cells can be caused by oxidation. It suggests that antioxidation is a pathway for protection of islets before transplantation.
