Intracardiovascular smoke-like echo always appears in the regions of stasis.Recently,we experimentally found that its appearance closely related to the erythrocytic rouleaux.(1)In vitro study:Erythrocytic suspension was observed by ultrasound and echofree can be seen on its sonogram.Under mi-croscope.the red blood cells presented dispersed phase.If equal amount of lymphocytic separated solution was put in the suspension,smoke-like echo appeared at the original fluid dark area and the red cells pres-ented pattern of rouleaux.(2)Animal experiment:Under physiological condition,velocity of blood flow israpid and echofree can be seen in the cardiovascular cavity.When blood flow velocity becomes slow or stasis,the shear force will reduce and even disappear,SO.red cells aggregated each other with their concave face and formed a rouleaux.As rouleaux structure was formed,its size became larger and it was nearer orlarger than the wavelength of ultrasound.therefre the reflections were produced and smoke-like echoappeared.It might be the mechanism for the formation of intracardiovascular smoke-like echo.

OBJECTIVE To investigate the antibiotic resistant phenotyping of Acinetobacter spp on NC21 panel. METHODS A total of 275 strains were isolated from clinical specimens.Acinetobacter were identified and antimicrobial susceptibility test performed.Phenotyping was according to David Livermore.Resistance phenotyping analysis included 13 antibiotics. RESULTS The susceptible results of 13 antimicrobial agents in 275 strains of Acinetobacter spp showed imipenem,amikacin,ampicillin-sulbactam,ciprofloxacin,tobramycin,ceftazidime,cefepime,gentamicin and trimethoprim had the greatest susceptibility(97.8%,88.4%,86.6%,82.2%,81.9%,9.6%,76.8%,73.8% and 73.6%,respectively).Beta-lactam agent-resistant phenotypes Ⅰto Ⅴ(wild type,penicillinase,cephalosporinase,penicillinase+cephalosporinase,multi-drug resistance mechanism) and nontyping were 67.3%,1.8%,1.8%,19.6%,0.7% and 8.8%,respectively.74.2% of 275 strains were susceptible to gentamicin,amikacin and tobramycin.Aminoglycosides resistant phenotype(gentamicin-resistant,gentamicin-amikacin-resistant,gentamicin-amikacin-tobramycin-resistant) and nontyping were 7.3%,1.1%,10.9% and 6.5%,respectively.8.7% were the penicillinase-cephalosporinase and gentamicin-amikacin-tobramycin-resistant phenotyps,those strains were all susceptible to imipenem and half to ampicillin-sulbactam. CONCLUSIONS Resistance phenotyping system should be useful in epidemiological studies of Acinetobacter and avoiding unnecessary antibiotics treatment,ampicillin-sulbactam as imipenem shows high antibacterial activities,aztreonam has a lower antimicrobial susceptibility than other 12 antibiotics.

Objective:To investigate the roles of vascular endothelial growth factor C(VEGF-C) and tumor infiltrating dendritic cells(TIDC) in invasion and metastasis of gastric cancer cells and to investigate the relationship between VEGF-C expression and TIDC infiltration in gastric cancer.Methods:Fifty-two patients,who were pathologically diagnosed with gastric carcinoma and received gastrectomy in the First Affiliated Hospital of Chongqing Medical University from 2004 to 2006,were enrolled in this study.The expression of VEGF-C and infiltration of dendritic cells were examined by immunohistochemical staining(S-ABC method),using anti-VEGF-C polyclonal antibody and anti-S-100 polyclonal antibody,and the relationship between them was investigated.Results:(1) In poorly differentiated and well/moderately differentiated cancer patients,the rates of positive of VEGF-C expression were 75.86% and 44.23%,respectively(P 0.05);the rates of serosa invasion in the high density group and low density TIDC patients were 36.36% and 70%,respectively(P

OBJECTIVE To investigate distribution and drug resistance status of Stenotrophomonas maltophilia.METHODS Microscan WalkAway-40 automatic analyzer from American Dade Company was used to identify bacteria.PCIZ and NC11 combination plate was used to perform susceptibility test in vitro.The data were analyzed by WHONET5.3 software.RESULTS The susceptibility to 15 antibiotics was tested in 42 clinic isolates of S.maltophilia from Jan 2005 to Sept 2006.The drug susceptibility test showed that SMZ-TMP had the lowest resistance rate(21.4%).Then resistance rate of S.maltophilia to cefoperazone-sulbactam was 23.8%.And 100.0% isolates were resistant to imipenem and aztreonam.CONCLUSIONS S.maltophilia has natural broad-spectrum resistance.We should strengthen its monitoring and control.

Tumor markers for early diagnosis of cancer is an important auxiliary mean,which for early tumor detection,monitoring and for judging curative effect of treatment regimens play important role.Clinical method for early diagnosis on ovarian cancer is the detection of serum CA125,however,its precision and specificity for early diagnosis are not enough.It has been found that in the development period of the patients with ovarian cancer,SMRP and CA125 is co-expression.This article reviews the value of serum mesothelin on diagnosis of epithelial ovarian cancer to provide reference on early diagnosis and treatment.

After chemoradiation therapy, tumor tissue metabolism changes earlier than its shape in advanced non-small cell lung cancr (NSCLC). Therefore, Positron emission tomography-computed tomography (PET-CT) can early assess the therapeutic efficacy and prognosis. But PET-CT might bring up some false negative or false positive outcome, while combined with the tumor markers, more accurate assessments of therapeutic efficiency and prognosis could be made for advanced(NSCLC).

Drug transporters are functional membrane proteins located in various tissues, which play vital roles in absorption, distribution and excretion of drugs, especially those located in intestine, liver and kidney. The expression and function of transporters will alter in diseases state, which affects the therapeutic effects of drugs by altering their pharmacokinetics. In this review, we focus on the alterations in related transporters and the effect on the drug therapy in common intestinal diseases, liver diseases, kidney diseases and diabetes mellitus.

OBJECTIVE:To investigate the characteristics and general regularity of ADR induced by Danhong injection,and to provide reference for rational drug use in the clinic. METHODS:Using“Danhong injection”and“ADR”as keywords,retrieved from CJFD,literatures published during 2005-2015 were collected and analyzed statistically in repsects of patient’s gender and age,disease and allergic history,drug combination,occurrence time of ADR and clinical manifestations,etc. RESULTS:A total of 24 literatures were collected,involving 360 cases. Female patients were more than male(66.11% vs. 33.89%);ADR often oc-curred within 30 min during medication(169 cases,46.94%);main clinical manifestations were lesion of skin and its appendents (163 cases,42.89%), systemic injury(72 cases,18.95%). The severe one would suffer form allergic shock. CONCLUSIONS:Great importance should be attached to the indication of Danhong injection,treatment based on syndrome differentiation,rational drug use and close monitoring. Constant vigilance is necessary to the occurrence of ADR.
