AIM: To study the apoptotic role of wild-type p53 in induction of plaque instability in atherosclerotic rabbits. METHODS: Fifty-four New Zealand White rabbits underwent balloon-induced abdominal aortic wall injury and then were fed on a diet of 1% cholesterol. At the end of the eighth week, the rabbits were randomly divided into two groups: group A and group B. Recombinant adenovirus carrying p53 and ?-galactosidase (LacZ) genes were injected in group A and B, respectively. Two weeks later, 10 rabbits each in group A and B was killed and the remaining rabbits all underwent pharmacological triggering with injection of Chinese Russell's viper venom and histamine. RESULTS: Compared with group B, p53 gene over-expression in group A resulted in a marked increase in number of positive apoptotic cells (2.5%?0.8% vs 1.0%?0.3%, P

Objective To analyze a population of cells on the right lower lateral of monocyte population in forward scatter/side scatter(FSC/SSC)(X-axis/Y-axis)scatterplot of peripheral blood leucocyte by flow cytometry(FCM)and its influencing factors.Methods The type of cells were identified based on cluster of differentiation antigen(CD)by FCM.The impact of temperature,hemolysin concentration,and incubation time was evaluated.Blood lipid tests were performed to observe the relation between them by statistical methods.Results (1) Phenotypo of this population of cells on the right lower lateral of monocytes in FSc/SSC scatterplot is CD+45 CD+13 CD+14 CD3- CD-19 ,which was the same as monocyte cells:(2)The monocytes in FSC/SSC scatterplot shifted to left side after using haemolysin;(3)The monocytes showed less resistance to antihemolysin in 37℃ than that in 220C:There were more monocytes shifting to left side with the increase of haemolysis time:(4)The swarming ratio of monocytes in patients (31.5%,40/126) Was higher than it in normal controls (5.1%,5/98)(x2=22.74,P<0.01);(5)The levels of total serum cholesterol(TC),triglyeride(TG),low density lipoprotein cholesterol(LDL-C), apoprotein B100(Apo B100) in patients with swarming monocytes were lower than that in the patients without swarming monocytes,(P<0.05).There was no statistical significance between the two groups with respect to levels of total bilirubin(TBIL),albumin(Alb),hish density lipoprotein cholesterol(HDL-C),apoprotein A I(Apo A I),lipoprotein(Lpa).Conclusions Peripheral blood monocytes can be divided in two groups in FSC/SSC scatterplot when analyzed with FCM.The presence of this population of cell Was related to resistance to hemolysin.It can be influenced by haemolysis time and incubation temperature.Therefore,the effect of swarming monocytes and abnormal cell membrane should be taken into consideration when the markers and function of monocytes are detected by FCM.

Objective To investigate the antibiotic resistance and the phenotype and genotype of metallo-β-lactamase in clinical isolates Chryseobacterium spp.Methods The MIC of 18 antibiotics in 50 Chryseobacterium spp.isolates was detected by agar dilution method.Phenotype of metallo-β-laetamase was detected by three-disc synergy test and modified three dimension test.Polymerase chain reaction(PCR)detection for metallo-β-lactamase gene was conducted for all isolates,and then the DNA sequence analysis was conducted for the PCR products which are positive for metallo-β-lactamase and identify genotype.conjugation experiment was used to study the transmission of metallo-β-lactamase encoding gene.pIs of β-lactamase was measured by isoelectric focusing assay. Results The antibiotic resistance of 50 clinical isolates of Chryseobacterium spp.against imipenem,Meropenem was 82.0%and 82.0%respectively.However,these isolated had high resistance to gatifloxacin.levofloxacin and rifampin compared with other antibiotics.Phenotype detection showed 33 isolated produced metallo-β-lactamase using three-disc synergy test and modified three dimension test,and the incidence of producing metallo-β-lactamase was 66.0%.Twenty isolateds producing Chryseobacterium indologenes were detected to have metallo-β-laetamase genotype by PCR amplification,among them 9 isolates containing blaIND-1 genotype and 10 isolateds containing blaIND-2 genotype.Strain CI-25 was identified to represent blaIND-LIKE genotype.Fourteen Chryseobacterium meningosepticum were detected to have metallo-β-lactamase genotype by PCR amplification,including 15 blaB and 2 blaGOB. The number of strain producing blaB1,blaB2,blaB3 and blaB11 in Chryseobacterium meningosepticum was 2,5,4 and 4,respectively. Conjugation experiments showed that metallo-β-lactamase encoding gene cannot be transfered. The extracted plasmid of 4 strains did not harbor metallo-β-lactamase gene.Strain C-5 was proved to have blaIND-1 gene,but its phenotype and IEF of metallo-β-lactamase was negative.Conclusions Chryseobacterium spp.had high frequency of multidrug resistance and high incidence for producing metallo-β-lactamase,and thus it was difficult to be treated.The gene of metallo-β-lactamase located on chromosome of Chryseobacterium spp.and cannot be transfered.There was negative or low lever of expression of blaIND-1.

OBJECTIVETo explore the expression of Ghrelin and high mobility group protein B1 (HMGB1) in the serum and the intestinal tissue of sepsis model rats, and to evaluate the effect of electro-acupuncture (EA) at Zusanli (ST36) on the expression of HMGB1 and Ghrelin.

METHODSForty-eight male Wistar rats were randomly divided into four groups, i.e., the sham-operation (sham), the cecal ligation and puncture group (CLP), the CLP + EA at Zusanli (ST36) group (EA), and the CLP + Ghrelin receptor blocking agent + EA group (GHSRA), 12 in each group. A sepsis rat model was prepared by CLP. The incision of the abdominal wall was immediately sutured along the ventral midline for rats in the Sham group. In the EA group EA at Zusanli (ST36) was performed 20 min after CLP surgery with the constant voltage (2 - 100 Hz, 2 mA) for 30 min. In the GHSRA group, Ghrelin receptor blocking agent, [D-Arg1, D-Phe5, D-Trp79, Leu11]-substance P (700 nmol/kg), was administered through intravenous injection immediately after CLP, and 20 min later, EA at Zusanli (ST36) was performed in the same way as for rats in the EA group. Blood samples were withdrawn 12 h after CLP. The serum levels of Ghrelin and HMGB1 were detected using ELISA. Ghrelin expressions and the number of Ghrelin immunopositive cell in the jejunum were determined by immunohistochemistry. HMGB1 contents of the jejunum tissue were detected by Western blotting.

RESULTSCompared with the Sham group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased and levels of Ghrelin and the expression rate of immunopositive cells significantly decreased in the CLP group (P < 0.05). Compared with the CLP group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly decreased, but levels of Ghrelin and the expression rate of immunopositive cells significantly increased in the EA group (P < 0.05). Compared with the EA group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased in the GHSRA group (P < 0.05), but there was no statistical difference in levels of Ghrelin between the two groups (P > 0.05). The serum level of HMGB1 was negatively correlated with Ghrelin in the Sham group, the CLP group, and the EA group (r = -0. 528, P < 0.01).

CONCLUSIONSEA at Zusanli (ST36) could inhibit the expression of HMGB1 in the jejunum of septic rats, and promote the expression of Ghrelin. The expression of HMGB1 was inhibited by Ghrelin receptor blocking agent, which suggested that the anti-inflammation of EA at Zusanli (ST36) might be associated with Ghrelin.
