Naive and chronically infected C57BL/6 mice were challenged percutaneously over the ear pinna with Schistosoma japonicum cercariae. After 15 hours, the number of EOS increased significantly in the skin of chronically infected mice. Inflammatory cells aggre-gated in the vicinity of schisto.somula or entrapped intact and disintegrated schistosomula, forming granulocytic micro-abscesses in both groups. Ultrastructure studies revealed that flattened EOS tightly attached to the schistosomulum surface and degranulated. Local tegument damage occurred in the area of attacbment. NEU adherence did not seem to be as intimate as EOS, and degranulation was not seen. The tegument of the attached schis-tosoniulum remained normal. The result suggested that EOS appeared to be the efficient killer cell against skin phase schistosomula of S. japonicum (Figs. 1-6).

Objective To study the therapeutic effect of Fumaderm in Freund' complete adjuvant-induced arthritis (AIA) in Spraque-Dawley rats. Methods Adjuvant-induced arthritis (AIA) was established by intradermal injection of 0.1 mL of Freund' complete adjuvant (CFA) in the palmar surface of the right hindpaw and Fumaderm was delivered by oral gavage for 28 days. After CFA injection, the edema of the hindpaw was determined every two days. On 28 days after CFA injection, the lymphocyte subsets of peripheral blood and the cytokines were determined by flow cytometry, meanwhile the histopathological examination of ankle-joints of the animals was performed. Results Fumaderm had a significant therapeutic effect on AIA. The hindpaw swelling was reduced significantly in a dose-dependent manner. The ratio of peripheral blood T lymphocytes was improved obviously. Multiparameter cytokine analysis from peripheral blood CD4+ T cells showed a decrease of proinflammatory cytokines and an increase of anti-inflammatory cytokines in Fumaderm treated animals. A strongly reduced inflammatory response in the joint synovium was observed. Conclusion Fumaderm has potential anti-inflammatory effects on AIA rats. Further investigation is needed to elucidate the molecular mechanism involved in the clinical effect observed in the AIA model.

OBJECTIVE: To study the mechanism and clinical significance of specific immunotherapy (SIT) on the expression changes of GM-CSF and IL-5 in the tissue samples of recurrent nasal polyps. METHOD: Perennial allergic rhinitis patients with recurrent nasal polyps were randomly divided into 2 groups. The experimental group of 19 patients was treated by SIT and standardized treatment (glucocorticoid nasal spray) , and the control group of 17 patients was only treated by standardized treatment (glucocorticoid nasal spray). We measured the expression levels of GM-CSF and IL-5 in the tissue samples of the nasal polyps by ELISA, and compared the results obtained before treatment with expression levels detected at 6 months and 1 year after the treatment. RESULT: The expression of GM-CSF and IL-5 in the recurrent nasal polyps reduced significantly (P < 0.05) in both groups after 6 months and 1 year post-treatment compared with pre-treatment, and the expression of GM-CSF and IL-5 in the experimental group was much lower than that of the control group. CONCLUSION SIT decreases the expression of GM-CSF and IL-5 and reduces the inflammatory reaction in the tissue samples of recurrent nasal polyps.

Background:Chronic neutrophilic leukemia (CNL) is a rare myeloproliferative neoplasm (MPN), since the first description of CNL in 1920, more than 150 cases have reported in the literature. The World Health Organization (WHO) recognizes CNL, as a MPN and, for the frst time, provides recognized criteria to permit the operational classifcation of this poorly defned disease. Until recently, the molecular pathogenesis of CNL was unknown and the diagnosis was based on morphological aspects, clinical criteria and exclusion of known genetic entities like the Philadelphia translocation indicative of CML, or JAK2 mutations indicative of MPNs. Recent discovery of highfrequency granulocyte-colony stimulating factor receptor (CSF3R) mutations in CNL identifes a new major diagnostic criterion, and lend more specificity to the WHO diagnostic criteria for CNL, which are variably applied in routine clinical practice. In 2013 Maxson et al., and Pardanani and colleagues identified granulocyte-colony stimulating factor 3 receptor (CSF3R) mutations in 8 of 9 (89%), and in 13 of 13 (100%) patients with CNL, respectively. CSF3R mutations fall into 2 classes: nonsense or frameshift mutations that lead to premature truncation of the cytoplasmic tail of the receptor (truncation mutations) and point mutations in the extracellular domain of CSF3R (membrane proximal mutations). These nonsense or frameshift mutations truncate the cytoplasmic tail of CSF3R, impair its internalization,and alter its interactions with proteins such as SHP-1/2 and SOCS family members. These structural and functional alterations are thought to perturb the capacity of CSF3R to regulate granulocyte differentiation and to increase granulocytic proliferative capacity. Thetwo types of CSF3R mutations may have differential susceptibility to classes of tyrosine kinase inhibitors,with CSF3R truncation mutations showing activation of SRC family–TNK2 kinase signaling and sensitivity to dasatinib, and CSF3Rmembrane proximal mutations strongly activate the JAK/signal transducer and activator of transcription pathway and are sensitive to JAK kinase inhibitors such as ruxolitinib.The most common CSF3R mutation in CNL is themembrane proximal mutation: T618I. On September 2012 we got a case (a 67-years-old Chinese man), which had fulflled the WHO diagnostic criteria for CNL with a novel mutation site of colony stimulation factor 3 receptor (CSF3R). In our case was identifed a membrane proximal mutations CSF3RT618I and also a unreported novel mutation site of CSF3R-H54A in the CD34+ and CD15+ cell fractionsby sorting bone marrow samples (BD FACSAria™ III; BD Biosciences) using a PCR-based DNA pyrosequencing method. Thus, we sought to determine CSF3R-FL, CSF3R-T618I, CSF3R-H54A mutations have some correlation with molecular pathogenesis of CNL.Objective:To determine CSF3R-FL, CSF3R-T618I, CSF3RH54A mutations that have some signifcance on the molecular pathogenesis of CNL.Materials/Methods:1. Plasmid construction. Plasmids were constructed by PCR amplifcation of the insert, restriction digestion and ligation using standard molecular biology methods, briefly: the host vectors pLV-EF1α-EYFP-N, pLP-2, pVSV-G, pLP-1 gag pol were purifed with Omegabiotek maxi prep kit and digested by restriction enzymes (ECO RI, NOTI). The linearized vectors were purified from agarose gel using a AxyPrep TM DNA Gel Extraction Kit and the concentration of the samples was estimated on an agarose gel stained with ethidium bromide.The inserts (CSF3R-FL, CSF3R-T618I, CSF3R- H54A) were generated by PCR, the sequences of the primer-pairs used and the conditions of the PCR reactions. The amplifed DNA fragments were purifed from agarose gels using AxyPrep TM DNA Gel Extraction kits and digested by ECO RI, NOTI was used to linearize the acceptor vector. Enzymatic reactions in the case of the i) insert: 100–3000 ng purifed PCR product was digested by appropriate amount of enzyme and 4 µl of 10x reaction buffer in 40 µl of fnal volume for overnight at the appropriate temperature; ii) vector: 2000–4000 ng plasmid DNA was digested by appropriate amount of enzyme and 2 µl of 10x reaction buffer in 20 µl of fnal volume for 4 hours at the appropriate temperature. When necessary Research on the Influence of new oncogenic CSF3R mutations in Chronic Neutrophilic Leukemia Otgonbat Altangerel1, Ming Feng Zhao2, Wu Ri Mao21Department of Internal Medicine, Division of Hematology, Mongolian National University of Medical Sciences, Mongolia 2Department of Hematology, Tianjin First Central Hospital, First Central Clinical College of Tianjin Medical University,P.R. China11 the digested fragments were purifed again and the concentrations of the inserts were estimated on agarose gels, as described above. A 1:3 vector: insert molar ratio was used for the ligation reactions. Chemically competent DH5α Escherichia coli bacteria were transformed with the products of the ligation reactions and were grown on Luria Bertrani (LB) agar plates containing the required antibiotic, such as ampicillin (Sigma). A day later single colonies were picked from the plate, inoculated into and grown overnight in LB medium containing with ampicillin. Plasmids were purifed from the overnight cultures as above and tested by restriction mapping for the presence of the insert. Selected clones were sequenced by Sanger sequencing.2. Lentiviral packaging system we used 3 main components, such as the lentiviral expression vector(Plasmid DNA of CSF3R-FL, CSF3R-T618I), the lentiviral packaging plasmids (pLP-1, pLP-2 plasmids that encode for gag, pol, and rev from the HIV or FIV genome and pVSV-G), 293TNN producer cells. We seed 1X105 293TNN cells per 10 cm2 culture plate in 2-3 ml of culture medium containing DMEM medium supplemented with 4 mM L-glutamine, 4.5 g/l glucose, and fetal bovine serum (10%) without antibiotics. Grow for 18-24 hours at 37 °C with 5% CO 2 so that the cell density reaches ~60 - 80% confluency at the time of transfection. We used a GFP as a positive control, to confrm transfection experiment was successful. Then we collected the cell culture supernatant, which is containing infectious pseudoviral particles.3. Transduction of Pseudotyped Viral Particles into the primary cell of mouse. In the fnal step we have used the Mouse Colony Forming Unit Assay using MethoCultTM to assess the effects of CNL-associated oncogenes on the morphology and number of primary murine cells derived bone marrow. For this purpose cells are transduced with either control, which is without viral construct or a construct expressing the oncogene of interest (CSF3R-FL, CSF3R-T618I).Results:1. On the Plasmid construction step we successfully extracted and purifcated of recombinant plasmids ofCSF3R-FL and CSF3R-T618I cloning, but we still didexperiment to obtain the recombinant plasmid CSF3R- H54A cloning.2. After 24 hours of transfection 293TNN Cells with Packaging Plasmids and the Expression Construct, cells we visualized with green fluorescence protein under the fluorescence microscope.3. The both two of CSF3Rcloning were capable of transforming murine colony forming cells. After transforming, CFU-GM colonies were counted manually by light microscopy seven days after plating. We found that the membrane proximal mutation (T618I) transformed CFU-GM colonies number was more than the full length non-mutants (CSF3RFL), which indicates that T618 mutation of CSF3R conferred the clonal advantage of CNL leukemia cells.Conclusions:1. The establishment of the plasmid reconstruction, lentiviral packaging system and Mouse Colony Forming Unit Assay were done successfully.2. We confrmed the transformation capacity of the CSF3R mutations, especially CSF3R-T618I was higher than CSF3R-FL. This result demonstrates that T618 mutation of CSF3R conferred the clonal advantage of CNL leukemia cells.3. Further studies will be continued and are needed to prove the effects of the novel mutation site CSF3RH54A on the transduced murine bone marrow progenitor cells by using CFC assay

Objective To investigate the relationship between cognitive function and emotional status in functional constipation patients.Methods Thirty-five functional constipation patients (the functional constipation group) and 24 healthy controls (the HCs) were enrolled in an event-related potential (ERP),behavior and electroeneephalogram study while performing an oddball auditory task.Response time,accuracy,latency and P300 amplitude were compared between the two groups.The Hamilton depression rating scale (HAMD-17),Hamilton anxiety scale (HAMA),symptom check list-90 (SCL-90) and Eysenck personality questionnaire (EPQ) were administered prior to the oddball task.Results The average HAMD-17,HAM A and SCL-90 (the somatization,obsessive-compulsive disorder,depression,anxiety and psychosis dimensions) scores of the functional constipation group differed significantly from those of the HCs.The intro-extraversion and neurosis dimensions of the EPQ were also significantly different.There was no significant difference in response time or latency between the two groups.The ERP results showed that the P300 amplitudes at the F3 and F7 sites were significantly different between the functional constipation group and the HCs.But there was no significant difference in P300 latencies at F3 or F7 between the two groups.Conclusions The findings suggest that patients with functional constipation are more susceptible to depression and anxiety,as well as somatization,obsessive-compulsive tendencies and other neurotic personality characteristics.Patients may employ psychological defense mechanisms to avoid the depression and anxiety.The ERP results imply there may be the implicit cognitive dysfunction with emotion in patients with functional constipation.

An analysis of the fundamental concepts for public hospital reform further defined public hospitals and other hospitals,business and non-business in nature,public benefits and welfare,as well as public benefits and profit-oriented hospitals.These distinctions can help reformers of public hospitals clarify their concepts,make clear the purpose and direction of the public hospitals reform,so as to speed up the reform with theory support.

This paper studied the development stages in terms of the public nature of public hospitals in China and analyzed the causes for their weakened public benefits.It proposed the principle of government guidance,achieving government purchasing of healthcare services as the roadmap,as well as building and improving the service purchasing system,performance appraisal system,and payment review system along with supervision system.These measures are designed to make public hospitals in their public benefit nature with scientific system design,powerful institutional guarantee,and efficient execution strategies.

Objective To investigate the change and clinical significance of serum procalcitonin (PCT) level in patients with community-acquired pneumonia (CAP).Methods One hundred and forty-five CAP patients were enrolled.Serum PCT level was measured by immunofluorescent antibody staining method.CURB-65 score and pneumonia severity index (PSI) score were used to evaluate the severity of the patients with CAP.Correlations between PCT and blood white blood cell (WBC) count,serum C-reactive protein (CRP),PSI score,CURB-65 score,hospitalization duration and mortality were analyzed with Pearson correlation analysis,Logistic regression analysis and so on.Results Serum PCT in patients with CAP showed positively correlated with CURB-65 score and PSI score (r =0.606,0.943,P＜ 0.01 ),and serum PCT was also positively correlated with age,serum CRP and hospitalization duration (r =0.753,0.233,0.281,P ＜0.01),but it wasn't correlated with blood WBC count (r =0.152,P ＞0.05).Logistic regression analysis showed that each increment of 1 μ g/L for serum PCT would increase 2.828-fold for the risk of death in CAP patients.Conclusions Serum PCT predicts the sensitivity and specificity of CAP with a similar prognostic accuracy with CURB-65 score and PSI score.Serum PCT in patients with CAP correlates with hospitalization duration and mortality.Therefore,it is a promising prognostic marker to evaluate the severity and outcome of CAP.It may serve as a useful marker for clinicians to evaluate the severity and prognosis of CAP.
