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.

OBJECTIVETo explore the better method of repairing the soft tissue defect of the distal foot.
METHODSThe soft tissue defect in the distal foot of six patients were repaired by the distally based dorsum pedis island flap pedicled with the bust deep artery and(or) the first dorsal metatarsal artery.
RESULTSSix patients were repaired in one stage, the biggest defect was 8 cm x 6 cm, all patients were followed-up 1 to 4 years, the function of foot was evidently improved, the patients were all satisfied with the operative results.
CONCLUSIONSThe bust deep artery and (or) the first dorsal metatarsal artery, with reliable blood supply, were easily dissected and with good texture. So far this kind of flap is a good choice in repairing the defects of the soft tissue in the distal foot.

Eight new diaryltriazine derivatives containing 4-allylamino and 4-azido substitutes guided by molecular docking have been designed and synthesized based on our previous work. The evaluation of HIV inhibitory activity demonstrated that all compounds were potent against HIV-1 replication. The most active compound 7c exhibited activity against HIV-1 (IC50 = 0.034 micromol x L(-1), SI = 6,475) and the double mutant strain (IC50 = 9.39 micromol x L(-1)) in the micromolar range, which was more potent than nevirapine.

OBJECTIVETo explore the relation of angiotensin-converting enzyme (ACE) gene polymorphism, angiotensin II type I receptor (ATIR) gene polymorphism and other factors on cerebral infarction.
METHODSOne thousand three hundred fifty-one subjects from Tangshan coalmine were enrolled with study method of cluster sampling. Face to face interviews were conducted to fill in questionnaires by trained interviewers. ACE gene, ATIR gene and inflammation factors including tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), IL-8, IL-10, C reactive protein (CRP), fibrinogen (Fg), fibrin monome polymerized velocity (FMPV), absorbance maximum (A(max)), FMPV/A(max), were measured.
RESULTSNo different prevalence rates of ACE genotype were found on cerebral infarction. The distributions of AA genotype of ATIR gene in the cerebral infarction was higher than that of the controls. The prevalence of AA genotype was higher than other groups, but the prevalence of combined genotype did not show much difference. Under the existence of factors that related to cerebral infarction, AA genotype frequencies were higher than those of non-smoking and with hypertension. IL-6, ATIR gene polymorphism, sex, FMPV/A(max) were strongly related to cerebral infarction. The level of IL-6 was higher than the normal ones.
CONCLUSIONSThe prevalence of cerebral infarction obviously increased in the hypertensive groups having AA genotype of ATIR gene. In the cerebral infarction groups, the level of IL-6 was higher than that in the normal population, indicating that these can be resulted from local inflammation and immunity reactivity. Environmental and genetic factors in the pathogenesis of cerebral infarction might have coordinating functions.

OBJECTIVETo study the association of beta-fibrinogen(Fg) gene -148 C/T and 448 G/A polymorphisms, plasma Fg concentration, molecular reactivity and the type of cerebral infarction.
METHODSGene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism. The plasma Fg concentration and the molecular reactivity were also determined.
RESULTSThe Fg concentration in MCI patients with T -148 allele was higher than that in PCI patients and controls. The MCI patients with A448 allele had higher Fg concentration, FMPV and FMPV/Amax when compared with controls, and had higher FMPV/Amax when compared with PCI patients.
CONCLUSIONFgB beta -148 and 448 mutational genotypes have impact on Fg concentrationì and therefore increase the risk of MCI.

AIMTo study the metabolites of penehyclidine hydrochloride (PH) raceme, a new anticholinerigic drug invented by the Institute of Pharmacology and Toxicology, Academy of Military Medical Sciences.
METHODSThree healthy rat urine samples were collected within 24 h after a single i.m. dose of PH raceme and PH-d5 [(5 + 5) mg.kg-1] simultaneously. The eight metabolites of PH raceme were identified by the methods of LC-MS/MS, GC-MS, FAB-MS and the stable isotope ion cluster. Mass spectrometry was operated in the positive mode for the method of LC-MS/MS.
RESULTSM1 and M1* were identified as the oxygenated products of PH in the cyclopentyl group; M2 and M2* were as the hydroxylated products of PH in the cyclopentyl group; M3 and M3* were as the oxygented and hydroxylated products of PH at the meta-position of cyclopentyl group; M4 and M4* were identified as the dihydroxylated metabolites of PH, the hydroxylated position were at the cyclopentyl group and quiniuclidinol ring of PH. Among them, M1 and M1*, M2 and M2*, M3 and M3*, M4 and M4* were the isomers of each other.
CONCLUSIONThese characteristics can be used for future structure elucidation in studies of the metabolites of PH optical isomers. The structure data of PH metabolites provide important information for the clinical use and for developing better anticholinerigic drug.

OBJECTIVETo investigate the clinical response, pathological complete response (pCR), tumor resection rate and safety of neoadjuvant chemotherapy with docetaxel and epirubicin (ET) for locally advanced breast cancer (LABC).
METHODSFrom March to December 2001, 40 women with LABC, aged from 28-67 (medium 48) years were alloted. Twenty patients had clinical stage IIIa disease, 15 had stage IIIb disease and 5 stage IV patients who had ipsilateral sura-clavicular metastasis. The dose was: epirubicin (E) 60 mg/m2, docetaxel (T) 75 mg/m2 every 3 weeks, with G-CSF given preventively. After 2 cycles of ET, a pilot clinical response evaluation was performed by investigators for each patient to decide if she should receive another 1-2 cycles of ET before surgery or radiation therapy.
RESULTSThirty-eight patients received 2-3 cycles of ET regimen. The pCR, clinical complete response (cCR) and clinical partial response (cPR) rates were 15.0%, 20.0% and 52.5%, respectively. Tumor resection rate in this group was 92.5%. Incidence of III/IV Grade neutropenia was 8.4%/14.0% of cycles, and 3 patients suffered from neutropenia with fever. Non-hematological adverse events were alopecia, nausea, vomiting, fluid retention, myalgia, arthralgia and nail disorders, which were mild to moderate.
CONCLUSIONNeo-adjuvant chemotherapy with a combination of docetaxel and epirubicin is effective and well tolerated by women with locally advanced breast cancer.
