Objective To identify the genotypes of ESBLs-producing Klebsiella pneumoniae isolates from the First Affiliated Hospital,Shantou University Medical College.Methods The MICs of 10 antibiotics were determined by agar-dilution against the clinical isolates of ESBLs-producing K.pneumoniae.PCR were performed with specific primers for blaTEM,blaSHV, blaCTX-M and blaOXA respectively.PCR products were cloned and sequenced.Results The results of PCR showed that a- mong the 83 strains of ESBLs-producing K.pneumoniae,75 were positive for blaTEM,41 positive for blaSHV,25 poitive for blaCTX-M,9 positive for hlaOXA.Three genotypes were found in 13 strains(15.7%),2 genotypes in 59 strains (71.1%) and single genotype in only 11 strains(13.2%).The genes of CTX-M-3,TEM-1 and SHV were found co-existent in 9 strains. The strains carrying 2 or 3 ESBL genes were more resistant to antibiotics than those carrying only 1 ESBL gene.Conclusions The genotypes of ESBLs-producing Klebsiella pneumoniae in this hospital are blaTEM,blaSHV,blaCTX-M and blaOXA. Most strains carry 2 or 3 ESBL genes.

In order to provide scientific basics for exploitation and sufficient application of Dendrobium officinale leaves resources, the phenol-sulfuric acid method was applied to determine the polysaccharide content. The monosaccharides were derivated by PMP and the derivatives were identified by HPLC-DAD-ESI-MS(n) and the contents of mannose and glucose were determined simultaneously. Similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (2004A) was employed to generate the mean chromatogram and similarity analysis of the samples was carried out. The results demonstrated that polysaccharide content, monosaccharide compositions and composition ratio had an obvious difference between stems and leaves. The polysaccharide content of stems was higher than that of leaves. Monosaccharide composition in leaf was significantly different from that in stem. The polysaccharide from stems was composed of mannose and glucose, however the polysaccharide of leaves was acid heteropolysaccharide and was mainly composed of five monosaccharides, including mannose, galacturonic acid, glucose, galactose and arabinose. The similarity value of the 14 batches was above 0.9, indicating that similarity of fingerprints among different samples was high. The study can provide evidence for expanding the medicinal parts of D. officinale.

OBJECTIVETo explore the therapeutic effects and mechanisms of Zhubi capsule on adjuvant arthritis (AA) in rats.
METHODThe model of rat was induced by intradermal injection of CFA. The perimeter of ankle joint was measured at different time points. Con A-induced splencyte proliferation was examined by MIT assay and the expression of IL-1, IL-6 in synovium was determined by immunohistochemical method.
RESULTAfter the preventive administration of Zhubi capsule (5.2, 2.6, 1.3 g x kg x d(-1), x 25 d), it was found that Zhubi capsule significantly inhibited the primary and secondary ankle joint swelling. The increased Con A-induced splencyte proliferation reaction and the activated IL1, IL-6 expression of AA rat were suppressed by the treatment with Zhubi capsule.
CONCLUSIONZhubi capsule has a therapeutic effect on AA rats, and its mechanism is related to the immunoregulative function.

OBJECTIVETo evaluate the mRNA and protein expressions of peroxiredoxin II (PrxII) in hepatocellular carcinoma (HCC) and their significance.
METHODSHCC was induced by aflatoxin B1 (AFB1) in 6 tree shrews (Tupaia belangeri chinensis). The expression levels of PrxII mRNA and protein were detected by reverse transcriptase polymerase chain reaction (RT-PCR) and Western blot on HCC tissues and on their surrounding liver tissues (para-HCC). Biopsied liver tissues were taken before the HCC induction (pre-HCC) from the same animals and from a group of blank controlled animals that served as controls. Liver biopsy specimens from 18 cases of human HCC and from 17 healthy human volunteers were studied using the same methods.
RESULTSThe mRNA and protein expressions of PrxII in tree shrew HCC tissues were significantly higher than those in para-HCC and pre-HCC tissues, and also higher than those in the liver tissues from the control animals (all P < 0.05). The expression levels of PrxII mRNA and protein in human HCC tissues were also significantly higher than those in their para-HCC tissues and in the human normal liver tissues (P < 0.05).
CONCLUSIONPrxII might play an important role in hepatocarcinogenesis and might be used as a molecular target for HCC prevention and treatment.

OBJECTIVETo investigate the use of a 32P application device (AD) in the treatment of condyloma acuminatum (CA) in the rectum, and to compare its clinical effect with that of the microwave therapy.
METHODSThis study included 107 cases of CA in the rectum, 99 males and 8 females, aged 21-58 (33.6 +/- 9.4) years. Forty-six of the patients (the AD group) were treated with a self-made 32P application device, which, as a tube-shaped carrier of radionuclide 32P colloid, was fixed in the rectum at the diseased part for medication at 4.9-8.2 Gy for 3-5 hours once and 1-2 times a week. The other 61 (the microwave group) were treated by microwave burning under local anesthesia. Both groups of patients were followed up for over 3 months for comparison of the therapeutic results and observation of the stability and reliability of the 32P application device.
RESULTSThe rates of cure, reoccurrence and adverse reaction were 84, 8%, 13.0% and 8.7% in the AD group, compared with 40.3%, 55.7% and 75.4% in the microwave group, with statistically significant differences between the two groups (P < 0.01).
CONCLUSIONThe 32P application device, with its advantages of low cost, easy operation, good effect, high safety and reliability, low recurrence, fewer adverse events and good acceptability, is highly valuable for the treatment of CA in the rectum.
