OBJECTIVE To investigate the manifestation,fungal spectrum,diagnosis,antifungal therapy and(outcome) of deep fungal infection(DFI) in patients with hematopoietic malignancies.METHODS Fifty-two(patients) of SFI admitted in Shandong Provincial Hospital during Oct 1998 to Sept 2004 were enrolled in this(investigation,) including 34 males and 18 females with mean age of 54 years old.Clinical data,such as manifestation,fungal(spectrum,) treatment and outcome,were observed prospectively and retrospectively.RESULTS Lower respiratory tract,gastrointestinal tract,urinary tract and blood were the main DFI infection sites by order of prevalence.The clinical manifestation was various among cases.Pathogen detection determined the subtypes of fungi were Candida albicans(57.14%),C.tropicalis(21.43%),yeast(47.14%),C.parapsilosis(7.14%),and Aspergillus((5.36%).) Nystatin,fluconazole,flucytosine,and(amphotericin) B were used alone or in(combination) to treat DFI.The rates of curing,improvement and death were 44.23%,23.08% and 32.69%,(respectively).(Among) 52 cases,25(48.08%) were occurred during Oct 2002 to Sept 2004,compared with 27((51.92%)) during Oct 1998 to Sept 2002,suggested the elevated incidence of DFI.CONCLUSIONS The incidence of DFI in patients with hematopoietic malignancies is increasing these years.The clinical manifestation of DFI may be nonspecific.It is critical to pay more attention to the fungal infection among the high-risk patients,therefore fungus detection from various(samples) should be recommended for the sake of early diagnosis of DFI. Though(C.albicans) remains the top in pathogen spectrum analysis,infection of other fungi tends to increase.The mortality of DFI is still very high thus more investigations about early diagnosis and treatment of DFI should be conducted.

Objective:To assess incidence of malnutrition and malnutrition risk of six department patients.Methods:The information of 1 200 patients were collected,200 in each of 6 departments in our hospital.Nutrition status was assessed according to Nutrition Risk Screening(NRS)published by ESPEN in 2001.Results:The incidence of malnutrition and malnutrition risk varied from 7.5% to 59% and 36% to 72% respectively in different department.Conclusion:The incidence of malnutrition is closely related to the kind and severity of the disease.It is nessissary to assess the nutrition status of high risk patients in time.NRS can be used simply and fastly in most inhospital patients.

Objective To investigate the correlation between Young′s elastic modulus (EI) using shear wave elastography (SWE) and liver pathology .Methods Liver biopsy was performed on 231 patients with chronic hepatitis B (CHB) under supersonic guidance ,and SWE with EI of liver was obtained concurrently .The correlation between measured liver stiffness and pathology was analyzed by using the liver pathology as golden standards .One‐way analysis of variance and Spearman rank correlation analysis were performed for the comparison between groups and correlation between two variables , respectively .Receiver operating characteristic (ROC) curve was used to explore the predictive value of shear modulus for the liver inflammation grades and fibrosis stages .Results The EI medians of different liver inflammation grades were 6 .78 kPa (G1) ,7 .30 kPa (G2) ,9 .93 kPa (G3) and 14 .93 kPa (G4) , respectively ,which were statistically different (H=55 .19 ,P<0 .01) .And EI medians of various fibrosis stages were 6 .62 kPa (S0 -S1) ,7 .15 kPa (S2) ,9 .78 kPa (S3) and 14 .62 kPa (S4) ,respectively , which were also significantly different (H=62 .14 ,P<0 .01) .EI was positively correlated with both liver inflammation grades (r=0 .454 6 ,P<0 .01) and liver fibrosis stages (r=0 .505 6 ,P<0 .01) .The areas under the ROC for G≥2 ,G≥3 and G=4 were 0 .68 (95% CI:0 .61 -0 .75) ,0 .77 (95% CI:0 .70 -0 .84) and 0 .85 (95% CI:0 .77-0 .92) ,respectively .The areas under the ROC for S≥2 ,S≥3 and S=4 w ere 0 .73 (95% C I:0 .66 -0 .79 ) ,0 .78 (95% C I:0 .72 -0 .85 ) and 0 .83 (95% C I:0 .75 -0 .91 ) , respectively .Conclusion The EI measured by SWE is correlated with liver pathology of CHB patients , which may be used to dynamically monitor the progress of liver fibrosis .

Objective:To understand the epidemic situation of Redondoviridae in Beijing and analyze its epidemiologic characteristics.Methods:Pharyngeal swab samples of healthy people and patients with acute respiratory infection in Beijing, including influenza like cases and severe acute respiratory infection (SARI) cases in hospitals were collected. Real time PCR was used to detect the nucleic acid of Redondoviridae. The positive samples were amplified and sequenced to analyze their species. The age and sex distribution of patients and species distribution of Redondoviridae were obtained through statistical analysis. Multiplex PCR was used to detect other common respiratory pathogens in the positive samples of Redondoviridae in influenza like cases and SARI cases, and the pathogenicity of Redondoviridae was analyzed.Results:The positive rates of Redondoviridae in healthy people and acute respiratory infection cases were 20.48% (189/923) and 11.23% (43/390), respectively, with a statistically significant difference ( P<0.05). The positive rate of male was higher than that of female in the healthy population, and the positive rate of the elderly group was higher than that of the adult group and the underage group, with a statistically significant difference ( P<0.05). The positive rate of male patients with acute respiratory tract infection was higher than that of female patients, but there was no significant difference. The proportion of Vientovirus in the positive samples of Redondoviridae was higher than that of Brisavirus, and the difference was statistically significant ( P<0.05). Among the throat swabs of respiratory tract infection cases, 43 were positive for Redondoviridae, of whom 24 were not detected for other pathogens. Conclusions:Redondoviridae widely exists in healthy people of all age groups in Beijing, and is also found in acute respiratory infection cases. The positive rate of Redondoviridae is different in different ages and genders. Both Vientovirus and Brisavirus were detected, and the proportion of Vientovirus was significantly higher than Brisavirus.

Objective:To understand the etiological characteristics of an acute gastroenteritis outbreak.Methods:Real-time polymerase chain reaction (PCR) and bacteria cultures were performed for the samples, including stool samples from patients and cooks, environmental swabs, raw food material (chicken meat), collected during the outbreak. Pulsed-field gel electrophoresis, antibiotics susceptibility test and whole-genome sequencing were performed for the Campylobacter jejuni isolates. Results:Four stool samples from patients were positive for Campylobacter jejuni by real-time PCR, in which 1 Campylobacter jejuni strain was isolated from a case who had no antibiotic treatment. Twelve Campylobacter jejuni and 7 Campylobacter coli isolates were obtained from 4 raw chicken meat samples. The Campylobacter jejuni strain isolated from the case was resistant to nalidixic acid, ciprofloxacin, chloramphenicol, florfenicol and tetracycline. The MLST analysis with the whole-genome sequences confirmed that the Campylobacter jejuni isolate from the case belonged to ST10075. Antimicrobial resistance genes cmeABCR, tetO/M and blaOXA-61 were found in the genome of the isolate from the patient by the whole-genome sequencing. No mutation in 23S rRNA was found and the C257T mutation in gyrA was identified in this isolate. Conclusion:Laboratory analysis indicated that Campylobacter jejuni infection might be the major cause of this gastroenteritis outbreak.
