Objectives To clarify the differential diagnostic value for iron deficiency anemia (IDA)and anemia of chronic disease(ACD)with analysis method of multiple parameters.Methods The serum concentrations of iron parameters (SI,TIBC,TF,SF and sTfR),inflammatory index(IL-1,IL-6,TNF-β),CRP and hepcidin were detected in patients with IDA and ACD by biochemical method and ELISA respectively.Results In the differential diagnosis of IDA versus ACD,the SF (98.6 versus 6.0,P=0)and sTfR/logSF[(13.1-±-4.4) versus (27.6 ± 16.5),P=0.002] had clinical value for the differential diagnosis.Inflammatory factors level was increased in two groups,only the difference in CRP between IDA and ACD showed a statistical significance.The hepcidin had the clinical value in differential diagnosis for single disease diagnosis of IDA and ACD and for differential diagnosis between IDA and ACD [(144.6 ±-1.9) versus (86.5-±-3.1),P＜ 0.05].Correlation analysis showed that the sTfR/logSF had a significantly negative correlation with SI(P=0.002),a significantly positive correlation with TIBC and TRF,and no significant correlation with inflammatory factors.The hepcidin had significantly positive correlation with IL-6 and TNF-β,and a significantly negative correlation with SI.The positive correlation was observed between sTfR/logSF and Hepcidin(r=0.376,P=0.005).Conclusions Analysis method of multiple parameters could make a differential diagnosis of ACD in the elderly.

Objective: To learn the epidemiological characteristics of infectious disease related public health emergencies in Zhejiang Province from 2010 to 2018 for the prevention and control. Methods: The surveillance data was extracted from National Public Health Emergency Management Information System. Descriptive epidemiology method was used to analyze main diseases as well as distribution characteristics of time and places. Results: A total of 445 events were reported, which caused 14362 cases and 34 deaths, with a attack rate of 0.69% and mortality rate of 0.24%. There were 298 events with less than 30 cases, accounting for 66.97%. The event classification was dominated by general events ( 242 events, 54.38% ) and ungraded events ( 201 events, 45.17% ). The main diseases were chickenpox ( 134 events, 30.11% ), hand foot mouth disease ( 59 events, 13.26% ) and other infectious diarrhea ( 51 events, 11.46% ). The incidence peaked from April to June ( 129 events, 28.99% ) and from November to December ( 131 events, 29.44% ). Ningbo ranked the top in the number of reported events ( 141 events, 31.69% ). Most events ( 322 events, 72.36% ) occurred in schools. Conclusions The infectious disease related public health emergencies in Zhejiang Province from 2010 to 2018 were mainly caused by chickenpox, hand-foot-mouth disease and other infectious diarrhea. The two peaks of the emergencies occurred from April to June and from November to December. Ningbo was the main area reporting infectious diseases, and schools were the main places.

ObjeCtive To investigate the value of protein biochip in the diagnosis of Lyme borreliosis. Methods The serum IgM and IgG antibodies against flagellin were detected by flagellin coated-and N-hydroxysuccinimide (NHS) modified-biochips in 82 patients with neuroborreliosis (NB),35 patients with erythema migrans (EM) and 44 normal controls.The results were compared with those from enzyme-linked immunosorbent assays (ELISA) and Western blot.Results The levels of both IgM and IgG antibodies were significantly higher in the NB patients than those in the normal controls (P

Objective To investigate the effect of sedation on respiratory mechanic dynamics, intrapulmonary shunt fraction,oxygen metabolism in patients with mechanical ventilation.Method Sixty patients with mechanical ventilation were divided randomly into control group and sedation group.Propofal was administered to patients,whose ramsay scores were kept atⅢorⅣlevels,in sedation group while the equal amount of normal saline was given in control group.Mixed venous blood and arterial blood samples were taken for blood gas analysis in both groups before and at 2 hours after administration.Heart rate,blood pressure,breathing rate and airway resistance all were recorded at the same time.Results There were no significant differences in oxygenation index,blood pressure,blood lactic acid,total lung static compliance and intrapulmonary shunt fraction between two groups before and after administration.Heart rate,respiratory rate,oxygen uptake and airway resistance of patients in sedation group were lower than those in control group,and partial pressure of oxygen in mixed venous blood of patients in sedation group were higher than those in control group.These differences were statistically significant.Conclusions Sedation can decrease oxygen uptake and airway resistance of patients with mechanical ventilation.However,no alteration in the oxygenation index,total lung static compliance and intrapulmonic shunt ratio can be observed.

An oxygen-tolerant denitrifying strain designated as H1 was screened by the procedures of shallow shaking and continuous aeration cultures.With the aid of an nnrS-gfp fusion responsive to nitric oxide (NO)and acetylene inhibition-GC procedure,it was shown that strain H1 was able to produce NO and N_2O but not N_2 under denitrifying conditions.Denitrifying processes were thus determined as NO_3~-→NO_2~-→NO→N_2O,with N_2O as the end product.Strain H1 could denitrify under shallow shaking conditions as well as in the initial atmospheric oxygen concentration ranging from 0～21%.Denitrification processed normally under continuous aeration at the rate of 2 L air per min in a 150 mL medium,but stopped under high aeration rate as 5 L air per min.16S rRNA gene sequence revealed that strain H1 shared 98% similarity to its closet relative Ralstonia taiwanensis,the genus where denitrifying bacteria are frequently found.

Patients with multiple myeloma (MM) have increased constantly in recent years, but treatment for patients with MM is currently unsatisfactory and it is necessary to develop new complementary therapies. Dendritic cells (DCs) are specialized antigen-presenting cells capable of initiating and regulating immune responses. Vaccination with tumor antigen-pulsed DCs has shown to be safe and possesses therapeutic effect against many tumors. In this review, the various types of MM-associated antigens and clinical trials on DC-based immunotherapy in MM are summarized, the development of DC immunotherapy for MM patients in future trials is discussed.

This present work is to study the chemical constituents of Swertia angustifolia. The whole plants of air-dried Swertia angustifolia was extracted with 90% EtOH. The water extract was suspended in H2O and extracted with petroleum ether, EtOAc and nBuOH, successively. The compounds were isolated and purified by column chromatography from the EtOAc fraction, and identified based on spectral analyses (MS, 1H-NMR, 13C-NMR). Fourteen compounds were isolated and characterized as 1, 8-dihydroxy-3, 7-dimethoxyxanthone (1), 1, 8-dihydroxy-3, 5, 7-trimethoxyxanthone (2), 7-hydroxy-3, 8-dimethoxyxanthone-1-O-β-D-glucopyranoside (3), 8-0-[β-D-xylopyranosyl-(1-6) -β-D-glucopyranosyl] -1, 7-dihydroxy-3-methoxyxanthone (4), (+) -syringaresinol (5), ferulic acid (6), trans-coniferyl aldehyde (7), sinapaldehyde (8), trans-coniferyl alcohol (9), 3, 4-dihydroxybenzoic acid (10), 2-hydroxybenzoic acid (11), isophthalic acid (12), 2-furoic acid (13), and 2-methyl-4(3H)-quinazolinone(14). Compounds 2-14 were obtained from this plant for the first time.
