Objective To analyse the clinical features,predisposing risk factors and treatment of hematologic diseases complicated by pulmonary fungal infection(PFI).Methods The medical records of 97 cases of PFI were retrospectively analyzed.Results Totally 201 fungal strains were obtained from 97 cases of hematologic diseases.The candida strains were 147(73.1%).Two-fungal infection was 17.5%,and secondary bacterial infection was 71.8%;relative death rate was 23.4%.Cure rate of Amphotericin B deoxycholate and Itraconazole was 67.7% and 63.7%.Conclusion Fungal infection is one of the main pathogens in hematologic diseases complicated by infection.Early diagnosis and treatment is the key to beneficial release and long time survival.Amphotericin B deoxycholate and Itraconazole were effective medicines for treated fungal infection.

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 typing and clinical significance of M-protein,to raise the understanding and diagnostic level through analysis of 639 patients with M-protein.Methods To analysis age,sex and disease of M-protein positive patients,charateristic and content difference of multiple myeloma(MM)and monoclonal gammopathy of undeterminal significance(MGUS).Results In 639 patients with M-proteinemia,there were 409 patients with IgG-type(64%),80 IgA-type(12.5%),79 IgM-type(12.4%),4 IgD-type(0.6%),9 ? light chain(1.4%),18 ? light chain(2.8%),27 double clone(4.2%),oligoclone(2.0%).There were 115 MM(18.0%),13 Waldenstrm's macroglobulinemia(2.0%),1 primary amyloidosis of kidney,19 non-Hodgkin's lymphoma(NHL)(3%),5 chronic lymphocytic leukemia(CLL)(0.8%),473 MGUS(74.0%).Conclusion M-proteinemia is a clinical phonomenon,mainly in MM and lymphocytic proliferative disease.There is an improving tendency in MGUS detectable rate.

OBJECTIVE:To establish a method for simultaneous determination of fatty acids in Isaria cicadae,Cordyceps militaris and C.sinensis,and to compare the difference of the contents of fatty acids among above medicinal herbs.METHODS:GC-MS method was adopted.Chromatographic condition:the determination was performed on TG-5MS gas phase capillary column with carrier gas of nitrogen at the flow rate of 1.2 mL/min.The inlet temperature was 290 ℃ by splitlesssampling;valve opening time was 1 min,and volume of sample was 1 μL.Mass spectrometry condition:the ion source is an electrospray ionization source.The temperatures of ion source and transmission line were 280 ℃,the initial temperature of the chromatographic column was 80 ℃ (gradient elution),ionization voltage was 70 eV.Solvent delay time was 5 min,and scan mass range was m/z 30-400.RESULTS:The linear ranges of tetradecanoic acid,pentadecanoic acid,palmitic acid,palmitoleic acid,heptadecanoic acid,heptadecenoic acid,docosahexaenoic acid,methyl oleate,linoleic acid,arachidonic acid,eicosenoic acid,diolefinic acid,eicosatrienoic acid,heneicosanoic acid,behenic acid,tricosanoic acid,lignoceric acid were 1.400-44.520 μg/mL(r=0.999 8),2.091-93.721 μg/mL(r=0.999 7),3.146-85.856 μg/mL(r=0.998 2),1.664-61.444 g/rnL(r=0.998 7),1.773-64.983 g/mL(r=0.999 5),1.781-68.421 μg/ mL (r=0.999 7),1.706-55.606 μg/mL (r=0.999 8),1.439-47.989 μg/mL (r=0.999 6),1.738-66.908 μg/mL (r=0.999 6),2.086-94.206 μg/mL(r=0.999 5),1.356-44.966 μg/mL(r=0.999 4),1.444-56.814 μg/mL(r=0.999 7),1.375-52.335 μg/mL(r =0.999 8),1.512-60.312 μg/mL(r=0.999 5),1.450-59.760 μg/mL(r=0.999 7),1.427-58.757 μg/mL(r=0.999 1),1.269-58.109 μg/ mL(r=0.999 3),respectively.The limit of quantitation was no more than 1 764.71 μg/mL,and the limit of detection was no more than 529.42 μg/mL.RSDs of precision,stability and reproducibility tests were all lower than 2.0％.The recoveries were 84.87％-108.93％ (RSD ranged 0.19％-2.23％,n=6).There were 17 fatty acids in C.militaris,16 fatty acids in Ⅰ.cicadae and 16 fatty acids in C.sinensis.The contents of unsaturated fatty acids in above medicinal herbs were higher than that of saturated fatty acids.The content of fatty acids in artificial cultivated Ⅰ.cicadae was mostly higher than other medicinal herbs.COCLUSIONS:The method is simple,accurate,stable and reproducible.It can be used for simultaneous determination of fatty acids in I.cicadae,C.militaris and C.sinensis.Above 3 kinds of medicinal materials.From the perspective of fatty acid content,the quality of artificial cultivated I.cicadae is best.
