Objective To describe the clinical features of invasive fungal disease in Huashan Hospital,Fudan University from January 2004 to December 2006.Methods The medical data were reviewed retrospectively for the patients with fungal infection, which was confirmed by positive fungal culture or microscopic examination with blood,sterile body fluid,deep tissue,sputum specimen or isolation of Aspergillus spp.and Cryptococcus spp.from bronchoalveolar lavage.The proven and probable cases of invasive fungal disease were included in this analysis.Results A total of 111 patients were diagnosed as invasive fungal dis-ease,including 104 proven cases and 7 probable cases.Sixty-one cases were community-acquired and the other 50 were nosoco-mial.The most common site of infection was bloodstream (51,45.9%),followed by central nervous system (44,39.6%)and respiratory system (14,12.6%).The most common pathogens were Candida spp.(50,45%),Cryptococcus (47,42.3%) and Aspergillus spp. (12, 10.8%). The community-acquired fungal infections were mostly found in central nervous system (44,72.1%),and respiratory system (12, 19.7%),mainly caused by Cryptococcus and Aspergillus. The nosocomial fungal infections occurred primarily in blood-stream (96.0%),mainly due to Candida spp.No underlying disease or risk factor was identified in more than half of the pa-tients with community-acquired infection,while almost all the patients with nosocomial fungal infection had underlying disease and predisposing factors.Indwelling venous catheter was closely associated with nosocomial bloodstream infection.Indwelling venous catheter lasted for more than 1 week in 64.7% of the patients with Candida bloodstream infection.The same fungal strain was isolated from both the cather and blood of the same patient in 11 cases.The overall mortality of these invasive fungal diseases was 14.4% (16/111).The mortality rate was 18.0% (9/50)in the patients with nosocomial invasive fungal infection, and 11.5% (7/61)in the patients with community-acquired invasive fungal infection.Conclusions The most common site of in-vasive fungal infection is bloodstream,followed by central nervous system,and respiratory system.Majority of the fungal patho-gens are Candida spp.,Cryptococcus and Aspergillus spp.The community-acquired invasive fungal disease is primarily meningitis caused by Cryptococcus.The nosocomial invasive fungal disease is mainly bloodstream infection caused by Candida spp.

Objective: To compare the efifcacy and safety of rivaroxaban and warfarin on thrombolytic disease prevention in very elderly patients. Methods: A total of 90 patients with high risk of venous thrombosis treated in our hospital from 2012-03 to 2014-03 were enrolled. The patients' mean age was (82.4±5.5) years and randomized into 2 groups: Rivaroxaban group, patients received oral rivaroxaban 10 mg/day,n=44 including 34 male and 10 female; Warfarin group, patients received oral warfarin, INR was monitored and kept at stable level of 1.6-2.5,n=46 including 38 male and 8 female. All patients were followed-up for 12 months. Hemoglobin and platelet levels, coagulation, liver and kidney functions, end point events were monitored before and 1, 3, 6, 12 months after treatment. Major efficacy endpoints included all-cause death, recurrent or new onset of venous thrombosis, pulmonary embolism, cerebral and cardiovascular events; major safety endpoints included massive hemorrhages, clinically relevant bleeding and worsening of liver, kidney functions. Results: No patient died during follow-up period. The average INRs in Warfarin group were (2.02±0.46), (1.98±0.54), (2.03±0.56) and (2.04±0.46) at 1, 3, 6 and 12 months of treatment. Efficacy and safety were similar between 2 groups, Warfarin group had 7 patients with massive hemorrhages at 12 months of treatment and it was 2 patients more than that in Rivaroxaban group which had no statistic meaning. Hemoglobin and platelet levels, coagulation, liver and kidney functions were similar between 2 groups.Conclusion: Oral rivaroxaban was effective for preventing thromboembolic disease in very elderly patients, 10 mg/day was a safe dose; efifcacy of rivaroxaban was similar to warfarin while it was easier to use and with better compliance.

Objective To evaluate efficacy of healthy canteen based-nutritional health promotion so as to provide evidence for popularization and application.Methods A total of 429 college professors and administrative staffs with a healthy canteen were selected as the intervention group in 2012 in Changzhou,and another 947 counterparts without a healthy canteen were selected as the control group.Those of the intervention group was further assigned to the ≥2 times/week and＜2 times/week subgroups.Blood pressure,fatty liver,serum triglycerides,blood glucose,total cholesterol,uric acid,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol and body mass index(BMI)were tested before and after the intervention.Results After the intervention,the mean serum glucose[(5.06±0.62)mmol/L],uric acid[(310.57 ± 71.79)μmol/L],total cholesterol[(4.88 ± 0.86)mmol/L],triglycerides[(1.39 ± 0.67)mmol/L]and low-density lipoprotein cholesterol[(2.51 ±0.62)mmol/L]of the intervention group were significantly decreased(t values were 7.513,2.126,2.062,3.731 and 8.891,respectively; all P＜0.05),and mean high-density lipoprotein cholesterol[(1.43±0.34)mmol/L]were significantly increased(t=-2.309,P＜0.05).After the intervention,mean serum glucose and uric acid of the control group were significantly increased(t values were-3.491 and-7.703,respectively; both P＜0.05),although there was no statistically significant difference of mean serum triglycerides,total cholesterol,low-density lipoprotein cholesterol and high-density lipoprotein cholesterol in the control group before and after the intervention(all P＞0.05).The abnormality rates of serum glucose,uric acid,total cholesterol,triglycerides,low-density lipoprotein cholesterol and BMI as well as the incidence of hypertension of the intervention group were significantly decreased after the intervention(x2 values were 4.202,3.940,4.031,7.305,59.422,4.273 and 7.385,respectively; P＜0.05).In the control group,although the abnormality rate of serum uric acid and the incidence of fatty liver were significantly inclined after the intervention(x2 values were 23.740 and 7.408,respectively; both P＜0.05),there were no significant difference of abnormal serum triglycerides,glucose,total cholesterol,low-density lipoprotein cholesterol and BMI as well as the incidence of hypertension before and after the intervention(all P＞0.05).Mean serum triglycerides[(1.15 ±0.68)mmol/L]and low-density lipoprotein cholesterol[(2.4 1±0.60)mmol/L]in the ≥2 times/ week subgroup were significantly lower than those of the＜2 times/week subgroup(t values were-4.884 and-2.513,respectively; both P＜0.05),and mean high-density lipoprotein cholesterol[(1.46±0.33)mmo]/L]of the ≥2 times/week subgroup was significantly higher than that of the＜2 times/week subgroup(t=2.032,P＜0.05).The abnormality rates of serum total cholesterol,triglyceride and low-density lipoprotein cholesterol in the ≥ 2 times/week subgroup were significantly lower than those in the＜2 times/week subgroup(x2 values were 3.963,9.947 and 4.589,respectively; all P＜0.05).Conclusion Healthy canteen based-nutritional health promotion model may provide an effective method to prevent and control the development of noncommunicable chronic diseases.

Objective To investigate the polymorphism profile of cytochrome P_(450)2C19 (CYP2C19) in Chinese patients with invasive fungal infections. Methods Two major single nucleotide polymorphism loci of the CYP2C19 gene (CYP2C19 * 2 and CYP2C19 * 3) were genotyped with PCR and restriction fragment length polymorphism (PCR-RFLP) in 134 patients with invasive fungal infections and 134 healthy volunteers. Allele frequencies and the proportions of metabolizer phenotypes were compared. Results In patients with invasive fungal infections, CYP2C19 * 1, CYP2C19 * 2 and CYP2C19 * 3 alleles showed frequencies of 58.2%, 36.6% and 5.2%. In healthy volunteers, the frequencies of CYP2C19 * 1, CYP2C19 * 2 and CYP2C19 * 3 were 63.4% , 34. 3% and 2. 2%. There was no significant difference in allele frequencies between the two groups. Of the patients with invasive fungal infections, 33. 6% were homozygous extensive metabolizers, 50.0% heterozygous extensive metabolizers and 16.4% poor metabolizers. Of the healthy volunteers, 40.3% were homozygous extensive metabolizers, 48.5% heterozygous extensive metabolizers and 11. 2% poor metabolizers. The proportions of metabolizer phenotypes were similar between the two groups. Conclusions Significant CYP2C19 polymorphism was detected in both groups. Approximately two thirds of the Chinese patients were either heterozygous extensive metabolizers or poor metabolizers. The genetic polymorphism may have important effect on drug metabolism in these patients

Mini health technology assessment (Mini-HTA) was developed from traditional HTA,based on the hospital needs.It is a very important decision making method and reference tool for the hospital policy makers.Currently there is no report of using Mini-HTA ease on introducing new equipment in China.Present paper introduces the Mini-HTA to provide reference for others hospitals in China.

Objective To analyze the clinical features of patients with uncommon fungal infections in central nervous system (CNS).Methods Thirty-five patients with uncommon CNS fungal infections who were admitted to Huashan Hospital from 1997 to 2010 were retrospectively reviewed.The pathogens,symptoms and signs.treatments of patients were evaluated.The data were analyzed by rank sum test and Fisher'S exact test.Results Twenty-nine of the 35 patients met the definition criteria of prover CNS fungal infections,while the other 6 had probable diagnosis.Predisposing factors were found in 86% of all patients.The most common pathogens were Aspergillus and Candida species.The symptoms and signs commonly occurred including fever(22 cases),headache(19 cases), cranial neuropathy(12 cases),and meningeal irritation sign(12 cases).High white blood cell count,high protein level,and low glucose level were the main findings of cerebrospinal fluid (CSF) analysis.Patients with cerebral aspergillosis were more frequently accompanied with immunocompromised conditions, and they often got CNS aspergillosis from hematogenous dissemination or direct extension of paranasal sinus infection.Cerebral granuloma and abscess were the common clinical characteristics of CNS aspergillosis.Cerebral candidiasis often arose from neurosurgical surgery or traumatic brain injury,and these patients were usually presented with meningitis.All patients were treated with antifungal drugs and (or) surgical intervention and 77%(27/35) of the patients achieved complete or partial responses. Antifungal agents combined with surgical resection might improve outcome of patients with CNS aspergillosis; while removal or replacement of drainage tubes in combination with antifungal treatment showed satisfactory efficacy in patients with cerebral candidiasis who usually had shunt manipulation. Conclusions The incidence of CNS fungal infection, such as cerebral aspergillosis and candidiasis, is increasing. Early diagnose and therapeutic intervention are crucial for improving outcome.

Objective To describe the distribution of mannose binding lectin (MBL) genetic polymorphisms in non-acquired immunodeficiency syndrome (AIDS) patients with cryptococcosis in China and to verify the association of MBL polymorphisms with susceptibility to cryptococcosis.Methods The case-controlled genetic association study was conducted and 167 non-AIDS patients with cryptococcosis and 208 healthy controls were recruited. Genome DNA was extracted from the peripheral blood and MBL gene was amplified by polymerase chain reaction (PCR). Six singlenucleotide polymorphisms ( SNP) of MBL gene were sequenced. The association of MBL polymorphisms with susceptibility to cryptococcosis were analyzed. The comparison between patients and controls was performed by chi square test or Fisher's exact test. The differences of MBL plasma concentrations between groups with different MBL genotypes were compared by single factor variance analysis. Results There were no differences between patients and controls in terms of MBL genotype frequencies, haplotypes and genotypes (all P>0. 05). Compared with healthy control, the deficient MBL-producing genotypes were strongly associated with cryptococcal meningitis (16. 5% vs 8. 7%,χ2=4.25, P=0.0392, OR = 2.09), particularly in patients without underlying immunocompromised conditions (21. 4% vs 8. 7%, χ2 =7. 15, P = 0. 0075, OR = 2. 88). Individuals with MBL deficiency genotypes showed significantly higher rates of central nervous system (CNS) cryptococcal infection rather than non-CNS cryptococcosis (16. 5% vs 3. 1%, Fisher's exact test, P = 0. 010, OR = 6. 13).The difference was even more significant in the immunocompetent patients (21. 4% vs 4. 0%, P =0.009, OR= 6. 55). Conclusion MBL deficiency is associated with cryptococcal meningitis and may play a role in CNS Cryptococcus infection.

Objective:To study the effect of immunological molecules expressive state upon the telomerase activation ( TA) of bone marrow mononuclear cells ( BMMNC ) in the hemopoietic microenvironment of patients with immune related hematocytopenia ( IRHS) ,and to explore the immunologic mechanism as well as the clinical significance of hematoclasis in marrow of IRHS patients .Methods:①TRAP-PCR-ELISA method was performed to detect the TA of BMMNC in marrow of 366 IRHS patients before and after therapy.②The molecules HLA-DR,anti-hunman IgG,FcγⅡR,mannose receptor ( MR),IL-17A and its receptor ( IL-17AR) were analysed by immunochemistry and immunofluorescence staining .③The flow cytometric ( FCM) was used to analyse the proportion of CD3+CD4+T cells as well as CD3+CD8+T cells ,CD3-CD19+B cells and CD3-CD16/56+NK cells in peripheral blood lymphocyte.60 cases of health examination were selected as the control group , and 30 cases hypoferric anemia patients were selected as disease control.The differences between patient group and control group were analysed with statistic method .Immunochemistry and immunofluo-rescence staining were performed to in situ analyze the activation-characteristics of immunocyte in bone marrow slides of IRHS ,and the dependablity of cellular immunologic injury was also checked.Results: ①The levels of TA was 0.261 7 ±0.021 6 before treatment , higher than the disease control group (0.061 6±0.031 3 ,P<0.01).Among of them HLA-B27+patients were higher than HLA-B27-patients (0.301 3±0.020 6 vs.0.192 3±0.012 9,P<0.05).Serious IRP patients with HLA-B27+IgG+were obviously higher than HLA-B27-IgG+patients (0.401 6±0.017 2 vs.0.221 1±0.011 0,P<0.01).②In marrow of HLA-B27+IgG+patients,both cell immunity and humoral immunity were in disorder in the hemopoietic microenvironment ,and immonocyte in marrow expressed HLA-DR, FcγⅡR,IL-17A,IL-17RA and MR,and Th,Ts,B cell and NK cell in peripheral blood increased in different degree ,inducing the in-flammation of haemocyte and lead to destruction.③Humoral immunity was in the dominant level in morrow;humoral immunity of HLA-B27-IgG+patients,immonocyte expressed FcγⅡR in high level,but IL-17A was seldom expressed,only CD19+B cell was increased slightly ,the antibody dependent cellular cytotoxicity ( ADCC) was the main mode of destruction.After therapy glucocorticoids associated with ciclosporin A ,the TA level of BMMNC decreased to 0 with devitalization.Conclusion: The telomerase activation of bone marrow mononuclear cells in IRHS is related with the immune state of hemopoietic microenvironment and the pathologic lesion degree of hema -topoietic cell in marrow.It is viral infection and immunological activation as well as a variety of inflammatory factors play a part in the immunologic injury that might be an important factor of the enhancement in TA.

Objective To study the clinical features and antifungal therapeutic effects in nonacquired immune deficiency syndrome(AIDS)patients with cryptococcal meningitis. Methods One hundred and fifty-four non-AIDS patients with cryptococcal meningitis admitted to Huashan Hospital, Fudan University from 1997 to 2007 were reviewed retrospectively. Clinical characteristics, initial antifungal therapies and outcome of these patients were analyzed. Continuous variables were analyzed using t test and categorical variables were compared by X~2 test or Fisher's exact test. Kaplan-Meier survival curves of different therapies were compared with log-rank test. Results Fifty-one patients (33.12%)had one or more predisposing factors. Headache, fever, meningeal irritation, vomiting and altered mental status were common clinical symptoms and signs during the course of diseases. The positive rates of cerebrospinal fluid(CSF)smear, CSF culture and detection of CSF cryptococcal capsular polysaccharide antigen were 88.44%,78.95%and 100.00%,respectively.Twelve cases were excluded because treatment durations were less than 7 days, including 9 died,2 discharged against medical advice due to illness exacerbation and 1 lost after against medical advice discharge. The remaining 142 patients were evaluated for therapeutic effects. The effective rates in amphotericin B (AmB)group, fluconazole group and AmB plus fluconazole group were 78.3%(36/46),33.3%(8/24)and 76.0%(38/50),respectively. The therapeutic effects in AmB group and AmB plus fluconazole group were superior to fluconazole group(X~2=13.6354,12.5509;P＜0.01).Eleven patients were lost during 1-year follow-up. The attributable and overall mortality in the remaining 143 patients were 19.58% and 28.67%,respectively.The 1-year survival rates in AmB group and AmB plus fluconazole group were significantly higher than that in fluconazole group. Conclusions The mortality of non-AIDS cryptococcal meningitis is still high,which is closely correlated with initial antifungal therapies. AmB alone or combined with flucytosine is related to both higher successful response and higher survival rate, while the efficacy of initial fluconazole alone or combined with flucytosine is poor.

OBJECTIVETo evaluate the methods of CT-guided percutaneous removal of osteoid osteoma.

METHODSFrom February 2003 to December 2003, there were 11 patients, at a mean age of 19.3 years old (from 14 to 32 years old). Seven cases were male, and 4 cases were female. Diagnosis was supported by the complete clinical and imaging file. Eleven cases with osteoid osteomas were treated with CT-guided percutaneous excision. The location involved were femoral neck (6 cases), acetabulum (4 cases), humeral neck (1 case). At first, CT scanning was done in the whole nidus with thin slices (2 mm thick), and the CT scan slice passing through the center of the nidus was selected. Then the whole nidus was removed by trephine along the guidewire which was inserted into the bone up to the nidus and was protected by the trocar. Finally complete lesion resection was checked with CT.

RESULTSNine cases had a final pathological diagnosis of osteoid osteomas. Complete pain relief was obtained in these patients after the day of operation. There were no complications, no recurrence and patients remained symptom free at follow-up of 8-18 months (mean, 15.2 months).

CONCLUSIONThe methods of CT guided percutaneous removal of osteoid osteoma is a minimally invasive technique that represents the efficacy and safety.
