Purpose:To study the clinical characteristics and therapy of acquired fungemia in acute leukemia patients. Methods:Retrospective analysis of the clinical characteristics and therapy of 34 acquired fungemia patients from 127 acute leukemia patients was done. Results:52 fungus strains were isolated from the blood culture of 34 acquired fungemia patients. Monilia was the main pathogen (92.4%). 24 fungemia patients also had bacteremia and the percentage was (70.6%). The overall mortality rate was 55.7% .The mortality rate of fungemia and fungemia together with bacteremia were (23.5%) and 76.4% respectively. The effective rates were 70.8% for diflucan treated group, 66.7% for the liposome treated group, and 75% for the combined treatment group respectively. Conclusions:Fungus infection has been one of the main causes of death in acute leukemia patients. So timely monitoring of the fungus infection and appropriate antifungal therapy have become the principle management to reduce the incidence rate and mortality rate of fungemia in acute leukemia patients. Diflucan and liposome are still effective antifungal drugs.

Objective To understand the distribution of the genotypes of ?-lactamases in Chryseobacterium/Flavobacterium spp.Methods Minimum inhibitory concentrations (MICs) of 43 Chryseobacterium meningosepticum strains,22 Chryseobacterium indologenes strains and 10 Chryseobacterium gleum strains against 15 antibiotics were determined by agar dilution method.3-D test and modified 3-D test were used to identify carbapenamase.2-mercaptopropionic acid inhibitory test was used to confirm metallo-?-lactamases (MBL).Genes of ?-lactamases were amplified with 6 pairs of primers special for Chryseobacterium/Flavobacterium spp.and the amplified genes were sequenced.Results MIC_(50) and MIC_(90) of quinolones were lower comparing to other antibiotics.MICs of C.gleum against 15 antibiotics were lower than other Chryseobacterium/Flavobacterium spp.Among 43 C.meningosepticum strains,26 strains (60.5%) produce MBL,but all strains (100%) produced extended-spectrum ?-lactamases (ESBLs);12 C.indologenes strains (68.8%) produced MBL;6 (60%) C.gleum strains had MBL.Genotypes of MBL in C.meningosepticum strains were Bla-B 1,2,3,5 and 11,and Bla-GOB 2,4,6 and 8,respectively.Only one genotype,namely CME-1,was identified for ESBL in C.meningosepticum.The genotype of MBL in 3 C.indolgenes strains was IND-1,and the 6 C.gleum strains contained CGB genotype.Meanwhile,there were 8 C.indolgenes strains and 3 C.gleum strains were confirmed to produce ?-lactamase,but their genotypes were unable to be detected using the current primers,implying that there were possible novel genotypes.Conclusions Investigation of genotypes distribution of ?-lactamase in Chryseobacterium/ Flavobacterium spp.can provide theoretical evidences and rational in the selection of antibiotics,control of noscomical infection and development of novel antibiotics.

Objective To assess the effects of surgical treatment for patients with blepharochalasis and its associated abnormali- ties. Design Retrospective case series, Participants 35 cases (52 eyes) with blepharochalasis in stable phase. Methods The correction of the abnormalities in upper eyelids: after designing the lid crease incision, the redundant eyelid skin and prolapsed fat were excised, and prolapsed lacrimal glands were sutured back into position in 18 cases (36 eyes) and ptosis was treated in 10 cases (16 eyes). The correction of abnormalities in lower eyelids: lower eyelid retraction was corrected in 4 cases (6 eyes). The correction of lateral canthus malformation: lateral canthus rounding was treated in 7 cases (14 eyes), accompanied with or followed by correction of baggy eyelid or ptosis. Main Outcome Measures The shape, location and movement of bilateral eyelids, the location of lacrimal glands and the cir- cumstance of tear secretion. Results During the follow-up of 6~60 months, the appearance and location of bilateral eyelids and can- thuses were satisfying, the function of eyelids were normal, and no dry eye symptoms were found. Two cases (3 eyes) appeared recurrent lacrimal gland prolapse 29 and 36 months postoperation and received surgeries for correction again. There was no recurrence after the second prolapse correction surgery in the follow-up of 18 and 24 months respectively. Conclusions Surgical treatment for patients with blepharochalasis and its associated abnormalities is safe and effective. Its recurrence rate is low.

Objective To observe the effect of intra-articular injection of dehydroepiandrosterone (DHEA)on the experimental osteoarthritis in rabbits and study the mechanism.Methods Forty rabbits un derwent unilateral anterior cruciate ligament transection(ACLT)and then divided into two groups randomly. 100?mol/L DHEA resolved in the dimethylsulphoxide were injected into the knees of experimental rabbits 4 weeks after transection,once a week for five weeks.Rabbits in the control group were treated under the same schedule using dimethylsulphoxide.All rabbits were killed 9 weeks after ACLT and the knee joints were evalu- ated by gross morphology and histology.The mRNA expression of metalloproteinases-3(MMP-3),tissue in- hibitor of metalloproteinases-1(TIMP-1)and interleukin-lbeta(IL-1?)in the cartilage and synovium was analyzed using reverse transcription polymerase chain reaction(RT-PCR).Results Gross morphologic in- spection and histological evaluation showed that the extent and grade of cartilage and synovium damage in the experimental group were less severe than the control group.The mRNA expression of MMP-3 in cartilage and synovium decreased significantly in the experimental group(both P<0.05).The mRNA expression of TIMP-1 in cartilage and synovium increased significantly in the experimental group compared with that in the control group(both P<0.05).No significant difference of IL-1?mRNA expression in cartilage was found between the experimental and the control groups(P>0.05).The mRNA expression of IL-1?in the synovium was signifi- cantly suppressed in the experimental group compared with that in the control group(P<0.01).Conclusion DHEA protects against cartilage degradation,alleviates synovium inflammation and inhibits the progression of osteoarthritis in the experimental model.Down-regulation of MMP-3 and up-regulation of TIMP-1 in cartilage and synovium and IL-1?in the synovium may be the mechanism of the protective effect of DHEA on os- teoarthritis.
