Objective To study the ecological characteristics of toxigenic fungi in soil of the suburban villages of Zhangzhou, Fujian. Methods 48 soil samples were collected from 24 natural villages in Zhangzhou and cultured in bengal rose agar plate, then the fungal count and species identification were carried out. Results The numbers of fungi in unit area in 48 soil samples were in the normal rang. 3357 strains of 34 fungal genera were found in sampled soil samples. Fusarium and Penicillium were the dominant genera, as well as Trichoderma, Parcilomyces, Cladosporium which were commonly detectable. 4 strains of Aspergillus flavas were found, 2 of them were toxigenic. Aflatoxin B 1 production were 6?7 ng/g respectively and they didnt produce AFB 2? AFG 1? AFG 2. 2 strains of A. versicolor both produced sterigmatocystin. Conclusion Aspergillus flavus showed lower proportion in mycoflora and weaker capability for producing aflatoxins in soil of suburban villages of Zhangzhou. This data obtained could be used as the basis for agriculture areal programme.

OBJECTIVE To investigate the drug resistance of Gram-negative bacteria in our hospital′s intensive care unit(ICU).It′s important to apply rationally antibiotics in clinic.METHODS We recruited all samples from infected patients of ICU during from Jan 2005 to Feb 2006.Totally 245 strains were identified to be Gram-negative bacteria.Kirby-Bauer method was performed to test extended spectrum ?-lactamases.RESULTS The first 3 of 245 strains were Pseudomonas aeruginosa(22.4%),Escherichia coli(20.8%) and Klebsiella pneumoniae(16.3%).Antibiogram analysis shew that CTX-M was the major type.CONCLUSIONS Imipenem keeps the highest sensitivity and antibacterial activity for Enterobacteriaceae and nonfermenters.Cefoperazone/sulbactam,cefepime,ceftazidime and amikacin keep the higher antibacterial activity.

Objective To compare the difference of the sense of security and social support between left-behind women and non left-behind women in rural area.Methods Social Support Rating Scale (SSRS) and security questionnaire(SQ) were used to measure social support and sense of security of 98 left-behind women and 151 non left-behind women.The data was analyzed by SPSS17.0.Results ①In the social support rating,compared with the non left-behind women,the left-behind women has lower score in the total score((40.561±6.692) vs (59.722±8.699),t=18.530),determining the control factor((21.459±3.891) vs (30.013±4.950),t=14.450) and human security factor((19.102±3.737) vs (29.709±4.849),t=18.392) and the differences were statistical significant(all P＜0.05).②In the social support rating scale,left-behind women had lower scores in total score,exploitation degree of support,subjective support and objective support than the left-behind women(all P＜0.05).③The total score and each factor score of security scale,and the total score and each factor score of social support rating scale in the left-behind women showed significantly positively correlated(r=0.245-0.507,P＜0.05).Conclusion The sense of security and social support of the left behind women were worse than that of non left-behind women.It is necessary to carry out psychological intervention for them.

OBJECTIVETo study the relationship between Chinese medical syndrome types and metabolomics of non-small cell lung cancer (NSCLC) patients.

METHODSTotally 120 NSCLC patients were assigned to asthenia syndrome group and sthenia syndrome group, 60 in each group. Meanwhile, 60 cases of benign pulmonary nodules in physical examinations were recruited as the control group. Tumor tissues or benign pulmonary nodules tissues were obtained by thoracoscope. Changes of their metabolites were observed using gas chromatography-mass spectrometry (GC-MS). Their differences were studied using principal component analysis (PCA) and partial least-squares discriminant analysis (PLS-DA). ROC curve analysis was performed in different metabolic compounds of sthenia and asthenia syndromes groups. The area under the curve (AUC) was calculated to evaluate the sensitivity of diagnosing syndrome types.

RESULTSCompared with the control group, difference existed in 16 compounds. Of them , contents of citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, linoleic acid, oleic acid, lactic acid, inositol were more in the two tumors group than in the control group. Difference existed in 10 compounds between the sthenia syndrome group and the asthenia syndrome group. Of them, citric acid, pyruvic acid, alanine, choline phosphate, glycerol phosphate choline, lactic acid, and inositol were more in the asthenia syndrome group than in the sthenia syndrome group. Contents of valine, glucose, and glutamine were more in the sthenia syndrome group than in the asthenia syndrome group. ROC curve analyses of different compounds indicated that AUC of lactic acid and glucose was more than 0.8 (P < 0.01); AUC of inositol, choline phosphate, and glycerol phosphate choline was more than 0.7 (P < 0.01); AUC of valine, citric acid, glutamine, alanine, and pyruvic acid was more than 0.6 (P < 0.05).

CONCLUSIONSThere existed certain correlation between CM syndrome types and metabolomics of lung cancer. Lactic acid, glucose, inositol, choline phosphate, glycerol phosphate choline, valine, citric acid, glutamine, alanine, pyruvic acid were sensitive diagnostic compounds, and the first four kinds were most sensitive compounds.

Objective To investigate the infection sites,the offending species,diagnosis and prognosis of deep fungal infections (DFI) in patients with systemic lupus erythcmatosus (SLE).Methods Fifty-one patients with fungal infections in 1466 SLE patients admitted to Peking Union Medical College (PUMC) Hospital from 2000 to 2006 were reviewed retrospectively.Results Candida albicans was ranked the first pathogen,followed by ncoformans and Aspergillus species.The infection sites were lungs,cerebral meninges and blood in the order of prevalence.The overall mortality was 20%(10/51).Aspergillasis carried the highest mortality which couht be as high as 80%.Hypoproteinemia,multiple focus of fungal infections,Aspergillasis and fungemia might he the independent risk factor for mortality.Conclusion Candida albicans is the most frequent species of fungal infections in SLE patients.Iungs are the most prevalent location of infection.Earlier diagnosis is important.Special attention should be paid to aspergillasis.

Abstract：Objective To analyse the level of measles antibody and serological susceptibility of the enterprise employees in Jin⁃ shan District，Shanghai in 2019，to provide references for measles prevention and control of enterprise employees. Methods A total of 1 796 employees were selected from 6 enterprises in Jinshan District by using a stratified random sampling method，of which serum samples from intravenous blood were collected and determined for IgG antibody level of measles by ELISA. Geo⁃ metric mean concentration（GMC）of measles IgG antibody，antibody positive rate and antibody protection rate were calculated and the susceptibility factors of measles in enterprise employees were analyzed by using the unconditional multivariate Logistic regression model. Results The GMC of measles antibody in 1 796 monitoring objects was 639. 71 mIU／mL，the positive rate was 87. 58% and the protection rate was 29. 06%. Multivariate Logistic regression analysis showed that the odds ratio（OR）of measles susceptibility was 1. 55（95% CI：1. 14 ~ 2. 12）in native subjects compared with non⁃resident subjects，while 2. 35 （95% CI：1. 35 ~ 4. 08）in subjects aged 40 ~ 49 years compared with those aged ≥ 50 years. Conclusion In 2019，the measles antibody level of enterprise employees in Jinshan District of Shanghai was low，and people aged 40 ~ 49，especially the nativeadults，wereathighriskofsusceptibilitytomeasles. Supplementaryimmunizationwithmeaslesvaccineshouldbecarried out for high⁃risk enterprise employees to reduce the risk of measles infection and control the epidemic situation of measles.
