Objective To investigate the distribution and antibiotic resistance of A.baumannii during the last five years in our hospital,the basis for the reasonable clinical use of antibiotic was provided to doctor.Methods The strains of A.baumannii isolated from clinical specimens during 2009-2013 were analyzed by VITEK-32 system,the antibiotic resistance was analyzed by WHONET5.4 software.Results A.baumannii strains were mainly isolated from sputum,accounting for 77.3％;the majority of the strains were isolated from ICU,accounting for 42.3％;the resistance rates of A.baumannii to antibiotics appeared increasing,and over 70％ except cefoperazone-sulbactam and imipenem.Conclusion A.baumannii is the major pathogen,and detection rate of A.baumannii is very high,antibiotic resistance status of A.baumannii is very serious.The management of antibiotic application should be strengthened,and the occurrence and prevalence of antibiotic resistant bacteria should be strictly controlled to prevent outbreak and epidemic of nosocomial infection.

Abstract: Fifteen novel ligustrazine-tetrahydroisoquinoline derivatives were designed and synthesized according to the association principle of pharmaceutical chemistry. The structures were identified by IR, NMR and ESI-MS. The inhibitory activities of platelet aggregation induced by ADP and AA have been measured by Bron method. Preliminary pharmacological results showed that compounds 7g, 7h and 7n had potent inhibitory activity against platelet aggregation induced by AA, and the compound 7o showed significant inhibitory activity against platelet aggregation induced by ADP.

Management of defects on the hand and foot with exposed tendons remains a major challenge for plastic surgeons. Here, we present a case of hand reconstruction with a totally laparoscopic peritoneal flap. The anterior rectus sheath was preserved in situ. The peritoneal free flap supplied by peritoneal branches of the deep inferior epigastric artery was retrieved by laparoscopy to cover the soft tissue defect of the hand. The defect of the dorsal hand was 17 cm ×12 cm. The peritoneal flap measuring 22 cm × 15 cm survived completely without any complications. A following split-thickness skin graft offered the suc- cessful wound closure. Motor and sensory function improved gradually within the first year follow-up. The totally laparoscopic peritoneal free flap is a good choice for reconstruction of the soft tissue de- fects accompanied by exposed tendons on the hand and foot.

Objective To explore the long-term outcomes of endoscopic submucosal dissection (ESD) of gastric GISTs.Methods Data of 25 patients with gastric stromal tumors,who underwent ESD,were reviewed in terms of clinical characteristics,histopathologic results,complications and long-term outcomes.Results Twenty-five patients underwent one-time complete removal of lesion, with a average tumor size of 3.0 cm (range,0.6 to 7.6 cm).The average time of operation was 65 minutes (range,15 to 154 minutes).one case was observed with intraoperative hemor-rhage of 200 mL blood,which was successfully managed by hemostatic forceps.Perforation with incidence rate of 16%occurred in 4 cases and was closed well with clips.Mucosal mechanical laceration of esophagus occurred in 1 case when the big tumor was taken out.The average length of hospi-talization was 7.3 days (range,4 to 21 days).A follow-up for 30 months (range,13 to 54 months) showed no tumor recurrence or metastasis. Conclusion ESD is an effective and safe endoscopic procedure to remove gastric GISTs for long-term outcomes in patients with no metastasis.

OBJECTIVETo identify enterovirus 71 (EV71) strains isolated from patients with hand, foot and mouth disease (HFMD) in Guangdong and Fujian provinces from 2000 to 2001 by using phylogenetic analysis.

METHODSAll 25 samples were first tested for enteric viruses by RT-PCR using enterovirus specific primers EV-1 and EV-2, and then were identified for EV71 by RT-PCR using EV71 specific primers 159S and 162A. The amplicons of 485bp segment (part of the VP1 gene) were cloned into pGEM-T and sequenced. A phylogenetic tree was constructed by comparison of the sequences with other 12 EV71 strains isolated from China, Japan, Hungary, and the United States including the prototype BrCr.

RESULTSThe positive rate of EV71 was about 20%. The sequence analysis showed that the new isolate (GZH2000) shared 94%-96% nucleotide identity with three strains isolated in 1998 and 2000, and 91% with a strain isolated in 1987 from Chinese mainland, but shared only 82%-84% homology with EV71 isolates studied abroad.

CONCLUSIONSEV71 is one of the important pathogens of HFMD in south China. The strains isolated from mainland were closely related with most isolates from Taiwan, but different from most EV71 strains reported abroad. The symptoms of EV71 infection in mainland were not as intensive as those described in Taiwan's outbreak.

OBJECTIVETo investigate the expression of p120(ctn) in non-small cell lung cancer (NSCLC) and its correlation with the clinical and pathologic parameters.

METHODSImmunohistochemistry (S-P method) was used to detect the expression of p120(ctn) in 143 NSCLC cases. The variation of protein expression was further analyzed in 36 cases by Western blot. The correlation with clinical and pathologic parameters was studied.

RESULTSImmunohistochemically, normal bronchial cells showed membranous expression for p120(ctn), while NSCLC was characterized by cytoplasmic or diminished membranous staining. The rate of abnormal p120(ctn) expression was 79.7% (114/143). There was a significant correlation between abnormal expression of p120(ctn) and tumor differentiation, clinical stage, lymph node metastasis and poor prognosis (< 0.05), but not histologic typing. Western blot showed that the total amount of p120(ctn) in normal bronchial cells was significantly higher than that in NSCLC. The p120(ctn) isoform 1 (120,000) and isoform 3 (100,000) were expressed in normal lung tissue, while there was a reduced expression or absence of isoform 1 in NSCLC.

CONCLUSIONThe expression of p120(ctn) is abnormal in NSCLC; p120(ctn) may serve as a useful prognostic marker for NSCLC.

OBJECTIVETo study the effect of supplemented Danggui Shaoyao San (DSS) and its disassembled prescriptions on function of lymphocyte in aged rats.

METHODSRats aged 18 months were administered with decoction of DSS and its disassembled prescriptions separately in groups for 3 weeks to prepare drug containing serum. Samples of ConA induced rats splenic lymphocytes proliferation was treated respectively with prepared drug serum, for testing their effect on lymphocyte proliferation using methyl thiazolyl tetrazolium (MTT) method, and isoprel (ISO) and propranolol were taken as the controls.

RESULTSThe A value of lymphocyte proliferation in the drug serum treated groups was significantly different from that in the control groups (P < 0.01), which could be reduced markedly after treatment with ISO, but could restore to the level before ISO treatment by adding drug serum or propranolol.

CONCLUSIONDSS and/or its disassembled prescriptions could raise the lymphocyte proliferation in aged rats significantly, it also shows antagonizing effect against the inhibition of ISO on lymphocyte proliferation.

OBJECTIVETo investigate the early changes of the blue-on-yellow (B/Y) perimetry in patients with early primary open-angle glaucoma(POAG).

METHODSThirty-one cases (45 eyes) of POAG underwent the central 30 degrees field examination of B/Y as well as routine white-on-white (W/W).

RESULTNo significant difference of mean index deficiency (MD) between B/Y and W/W perimetry was detected (P>0.05). However, there were marked changes in index GHT (glaucoma hemisphere test) and more defect points in B/Y visual field than those in W/W (P<0.01).

CONCLUSIONB/Y perimetry might be more sensitive than W/W perimetry a potentially more and valuable method in detection of early POAG lesion.
