Objective To investigate the clinical significance of neutrophil parameters Neut‐X and Neut‐Y in the diagnosis of blood stream infection(BSI) .Methods The data in106 patients with blood stream infection and 51 cases in the healthy control group were retrospectively analyzed .The results of WBC ,neutrophil percentage ,Neut‐X ,Neut‐Y and procaclitonin (PCT ) were compared .Results Neut‐X and Neut‐Y in the BSI group were 1 393 .5 ± 33 .4 and 416 .2 ± 30 .0 respectively ,which were signifi‐cantly higher than 1 371 .9 ± 32 .7 and 391 .7 ± 23 .7 in bacterial culture negative group and 1 347 .2 ± 26 .2 and 371 .9 ± 21 .5 in the healthy control group ,the differences were statistically significant (P<0 .05) .Neut‐X and Neut‐Y had good correlation with PCT . Neut‐X and Neut‐Y levels in the Gram‐negative bacterial group were higher than those in the Gram‐positive bacterial group .Conclu‐sion Neut‐X and Neut‐Y parameters in the patients with BSI are significantly increased and can be used as the assistant diagnosis parameters of blood stream infection .

Objective To investigate the performance of surgical management in facial skin malignancies.Methods From January 2000 to December 2006,65 patients with facial skin malignancies,including47 cases of basal cell carcinoma.10 cases of squamous cell carcinoma,3 cases of dermatofibrosarocoma protuberans,2 cases of malignant melanomas,and one case of malignant acanthoma,hemangioendotheliosar-coma and sebaceous carcinoma,respectively,were collected and managed with wide resection followed by reconstruction.In order to achieve a thorough resection,frozen sections were prepared and subjected to pathological examination during the operation process to ensure the margins of resection were free of malignancy.Reconstruction was carried out by direct closure,or with local random flaps,extended flaps,free skin grafts.Resuits All defects were managed by one-stage reconstruction.The survival rate of skin flaps/grafts was 100%,and a satisfactory appearance and function was achieved.During the follow-up from 6 months to 5 years,local relapse was observed in one patient with basal cell carcinoma and one with squamous eell carcinoma,lymphatic metastasis in one with squamous cell carcinoma.Distant metastasis occurred in a patient with malignant melanoma.who died consequently.Conclusions Thorough resection is the key to prevent relapse of facial skin malignancies after surgery.Appropriate reconstruction may favor the restoration of facial appearance,and local random flaps appear to be the best reconstruction strategy.

To study the coumarins of Anemone raddeana Regel, the compounds were separated by silica gel column chromatography and HPLC. Their structures were identified by their physicochemical property and spectral analysis. Two new compounds were isolated and identified as 4, 7-dimethoxyl-5-methyl-6-hydroxy coumarin (1) and 4, 7-dimethoxyl-5-formyl-6-hydroxycoumarin (2). The bioassays indicated that compounds 1 and 2 could significantly inhibit the proliferation of cancer cell, and showed the agonist effect on the transactivity of retinoic acid receptor-alpha (RARalpha). In addition, the two compounds had inhibitory effect against human leukocyte elastase (HLE).

Objective To discuss the characteristics of extended-spectrum beta-lactamases(ESBLs)-producing Shigella and the relation between them and drug-resistance plasmid. Methods The suspicious ESBLs-producing isolates were screened by K-B disc diffusion method, and the ESBLs-producing strains were confirmed by confirmatory test recommended by the National Committee for Clinical Laboratory Standards. Furthermore, the partial blageneof these isolates were detected by PCR using universal primers for TEM, SHV, CTX-M-1 group, CTX-M-2 group and CTX-M-9 group, respectively. The entire blaCTX-M-9 and blaTEM were amplified by PCR using the primers outside the open reading frame (ORF) of these β-1actamases and products were directly sequenced. The conjugation experiment was performed to determine whether the resistance was transferable. Minimal inhibitory concentration (MIC) was detected with double agar dilution method. Results Of the 275 isolates, 12 strains were identified as ESBLs producers. Among them, 8 strains were CTX-M-14 carriers and 4 strains were CTX-M-3 carriers. All ESBLs-producing isolates are positive for plasmid conjugative transfer test. The transconjugants are only resistance to betalactams. Conclusions High resistance to beta-laetams in Shigella is caused by production of ESBLs in the local area. The ESBLs-produeing isolates can transfer the drug resistance through lateral transfer of plasmid.

OBJECTIVE: To compare the vertigo controlling situation between the endolymphatic sac decompression(ELSD) and semicircular canal occlusion (SCO) in stage 4 Ménière disease. METHOD: Fourteen patients who underwent endolymphatic sac decompression and 9 patients who underwent semicircular canal occlusion from 2009 to 2013 were followed. All patients has complete preoperative examination and postoperative follow-up. RESULT: The vetigo control of the patients underwent endolymphatic sac decompression: completely control 35.7%; basic control 28.6%; partly control 14.3%; the vetigo control of the patients underwent semicircular canal occlusion: completely control 88.9%; basic control 11.1%. CONCLUSION ELSD and SCO are alternative methods for the patients of stage 4. SCO has a much highter complete vertigo control rate. For the patients without practical listening, SCO is a better choice.

OBJECTIVE: To study on the expression and significance of MMP-2 and MMP-9 in the nasus epithelial carcinoma and their signification. METHOD: Fifty cases of epithelial carcinoma tissue and 50 cases of normal nasus tissue were detected for MMP-2 and 9 by immunohistochemistry technique (SP), and analysed their relationships between expression of MMP-and some clinical symptoms. RESULT: The positive ratio of expression of MMP-2 in 50 cases of epithelial carcinoma was 52.0% (26/50), which was significantly higher than those in the normal nasus tissue 28.0% (14/50), P < 0.05. The positive ratio of expression of MMP-9 in 50 cases of epithelial carcinoma was 58.0% (29/50), which was significantly higher than those in the normal nasus tissue 10.0% (5/50), P < 0.05. CONCLUSION It was suggested that there was a close relationship between pathogenesis and development of nasus epithelial carcinoma and the expression of MMP-2, MMP-9 in the epithelial carcinoma tissues. The positive results of MMP-2, MMP-9 is partly valid for diagnosis of prognosis rate of MMP-2 and MMP-9 expression was high in nasus epithelial carcinoma tissues, MMP-2 and MMP-9 expression levels might be able to provide prognostic information.

Histone lysine specific demethylase 1 (LSD1) has been recognized as an important modulator in post-translational process in epigenetics. Dysregulation of LSD1 has been implicated in the development of various cancers. Herein, we report the discovery of the hit compound (IC = 3.93 μmol/L) and further medicinal chemistry efforts, leading to the generation of compound (IC = 49 nmol/L, and = 16 nmol/L), which inhibited LSD1 reversibly and competitively with H3K4me2, and was selective to LSD1 over MAO-A/B. Docking studies were performed to rationalize the potency of compound . Compound also showed strong antiproliferative activity against four leukemia cell lines (OCL-AML3, K562, THP-1 and U937) as well as the lymphoma cell line Raji with the IC values of 1.79, 1.30, 0.45, 1.22 and 1.40 μmol/L, respectively. In THP-1 cell line, significantly inhibited colony formation and caused remarkable morphological changes. Compound induced expression of CD86 and CD11b in THP-1 cells, confirming its cellular activity and ability of inducing differentiation. The findings further indicate that targeting LSD1 is a promising strategy for AML treatment, the triazole-fused pyrimidine derivatives are new scaffolds for the development of LSD1/KDM1A inhibitors.
