Objective Serologic proteome analysis method (SERPA) was used to compare the different of the serum proteins between normal and pancreatic cancer patients' serum, and to find a new specific pancreatic cancer marker. Methods HPLC was used to eliminate albumin from the serum, two-dimensional electrophoresis was used to separate the proteins. After imaging collection and analysis, the different proteins between pancreatic cancer and normal subjects were cut for mass spectrometry. Results Four discrepancy proteins were obtained. Guanylate cyclase-activating protein 2 was highly expressed in normal serum but not pancreatic cancer. Hp2-alpha, transthyretin and KIAA1018 protein were highly expressed in cancer patients'serum but not normal people. Conclusions KIAA1018 may become a promising tumor marker for screening and early diagnosis of pancreatic cancer.

[Abstract ] Objective To understand the identification and in vitro antifungal susceptibility of Penicillium marneffei(PM)in yeast phase,and guide clinic antifungal application.Methods Strains isolated from blood and bone marrow of 23 patients infected with PM in a hospital between 2009 and 2016 were collected,colony morpholo-gy of PM in yeast phase was observed,susceptibility to itraconazole,voriconazole,amphotericin B,and fluconazole were detected with E-test method.Results Colony morphology of PM were as follows:direct microscopic examina-tion of Wright’s staining of tissue specimens found visible oval or round spore with apparent septum,and mainly lo-cated in macrophage;Gram staining of blood culture specimens found that strains were with bulbous and slightly curved ends,occasionally branched and with septum. PM was dimorphic fungi,presented mycelium at 28° C,pro-duced red pigment and diffused into medium;PM presented yeast form at 35° C,there were typical colony morpholo-gy. Minimum inhibitory concentrations (MICs)of itraconazole,voriconazole,amphotericin B,and fluconazole to PM in yeast phase were 0.002-0.016,0.012-0.125,0.002-0.500,and 0.500-16.000μg/mL respectively. Conclusion Typical colony morphology and fungal spore of PM in bone marrow and peripheral blood are important features for identification. PM is most susceptible to itraconazole,followed by voriconazole and amphotericin B, while fluconazole is less susceptible.

OBJECTIVE To estimate the prevalence of nosocomial infections(NI)and the use of antibacterials in pediatric department,find the problems in management of hospital infection and provide the scientific basis for formulating prevention and control measures.METHODS By bed-visiting and patients' medical records checking,we filled out unified case questionnaire.All patients were investigated on August 22,2007.RESULTS Of the 86 patients investigated,the prevalence rate of NI was 4.65%.There were 19 kinds of antibiotics used daily.The daily antibiotics use rate was 95.35%;all of the infection sites were in upper respiratory tract and delivering rate of bacterial culture was only 14.63%.CONCLUSIONS Management and training should be strengthened on antibacterial drug in the pediatric department.The reasonable use of target antibiotics could prevent the abuse ment.

Objective To prospectively investigate the association between serum uric acid concentration and the risk of brain infarction in Chinese adults.Methods In this prospective cohort study,a total of 95 738 participants (aged 18-98 years old) were included and were categorized into sex-specific quintiles according to serum uric acid concentration which were collected during 2006-2007 by health examinations.The study was followed up for an average of 4 years.We used Cox regression models to calculate hazard ratios (HR) and their 95% confidence intervals (CI).Results (1) Higher concentrations of serum uric acid were associated with older age,obesity,higher blood pressure,higher serum concentrations of total cholesterol,triglycerides,and high sensitivity C-reactive protein,smoking,alcohol drinking,history of hypertension,hyperlipidemia and atrial fibrillation,and antihypertensive medication use.(2) The incidence of brain infarction for sex-specific quintiles were 0.84% (33/3913),0.35% (14/3985),0.44%(17/3888),0.54% (21/3909),0.91% (35/3860) in women (x2 =15.676,P =0.003) and 1.18%(180/15 238),1.26% (191/15 170),1.11% (170/15 323),1.45% (221/15 216),1.82% (277/15 236)in men (x2 =36.641,P =0.000).(3) After adjusting for potential confounders,including age,body mass index,blood pressure,fasting plasma glucose,total cholesterol,triglyceride,smoking,alcohol,and medical history of major chronic conditions and antihypertensive medication use,the HR (95% CI) of brain infarction across serum uric acid quintiles were 2.06 (1.14-3.72),0.91 (0.45-1.84),1.00 (ref),1.11 (0.58-2.09),1.31(0.73-2.34) in women and 1.07 (0.86-1.34),1.02 (0.47-2.25),1.00 (ref),1.23(1.00-1.52),1.24(1.01-1.52) in men.Conclusions In this prospective cohort study,we find a U-shaped relationship between serum uric acid concentrations and brain infarction,a higher risk of developing brain infarction in association with low or high serum uric acid concentrations.Women with lowest or highest serum uric acid concentrations and men with higher serum uric acid concentrations are more likely to develop brain infarction.This probably because women have lower serum uric acid concentrations relative to men.Confirmation of our findings in larger cohorts with longer follow-up duration is warranted.
