The 8p11 myeloproliferative syndrome is a rare hematologic malignancy that involves the fibroblast growth factor receptor 1 (FGFR1) gene at chromosome 8p11.The clonal change of the FGFR1 rearrangement is present in BM cells,and in the T-lymphoma cells in the LN.The hematological stem cells transplantation is the only method that can cure this rare hematologic neoplasma.

AIM: To study the dynamic levels of tumor necrosis factor alpha (TNF-?), interleukin-6 (IL-6) and gamma interferon (IFN-?) produced by human dendritic cells infected with Dengue virus. METHODS: Monocytes isolated from healthy human peripheral blood were incubated in medium with GM-CSF and IL-4 for more than 7 days. DCs were then collected and identified by scanning electron microscope, immunohistochemistry and lymphocytes stimulatory ability. Human dendritic cells (DC) were infected with Dengue-2 virus (DV-2) in vitro, culture supernatants were collected in different time postinfection (6 h, 12 h, 24 h, 48 h and 72 h), DV antigen in human dendritic cells were demonstrated by an indirect immunofluorescent assay (IFA), production of TNF-?, IL-6 and IFN-? in the culture supernatants were evaluated by ELISA. RESULTS: After 7 days, typical dendritic cells could be obtained. Virus antigen were detected in infected DC by IFA. Dengue virus induces TNF-? and IL-6 secretion from DC and does not induce IFN secretion. CONCLUSION: Human dendritic cells are target of dengue virus infection. TNF-?, IL-6 production from DC are increased with DV infection. Dendritic cells may play an important role in DV pathogenicity and immunity.

ObjectiveTo investigate the effect of Jiawei Glutinous decoction on gouty nephropathy. Methods54 patients with gouty nephropathy were randomized into two groups, 31 patients in the treated group were treated with Jiawei Glutinous decoction, and 23 patients in the control group were treated with allopurinol. Blood uricacid (BUA), renal function, β2-microglobulin (β2-MG) and 24 h urine protein of patiens in two groups were measured before and after treatment.ResultsImprovements of symptoms and renal function as well as decreasing of BUA, β2-MG and 24h PRO in the treated group was superior to those in the control(P<0.05).ConclusionJiawei Glutinous decoction present good effect in treating gouty nephropathy.

respectively)was significantly higher than that for digital anterograde venography (0.684 and 0.587,P =0.026,respectively).Conclusion Diagnostic accuracy and detection rate of residuaI or recurrent varicose veins with CT phlebography are found to be more superior than that with digital anterograde venography which has high guidance value in preoperation and assesses the efficacy of post-surgery treatment.

Objective The animal model of rheumatoid arthritis was established in Lewis rats by a single intradermal injection of pristane. Methods The degree of pathogenicity and the pathological characteristics were assayed by histiopathological techniques and joint roentgenography. Results The incidence of arthritis in rats immunized by pristane was 62.5%. Peripheral joints were mainly involved. A chronic relapsing and progressive arthritis was developed.As showed by histopathology and roentgenography, typical arthritis pathology such as synovial proliferation, articular cartilage and bone erosien were found. Conclusion Pristane induced arthritis mirrors human rheumatoid arthritis and is a very good animal model for rheumatoid arthritis.

Objective To investigate micrometastasis in axillary lymph nodes and its relationship with nm23 expression of the tumor tissue in breast cancer patients. Methods Paraffin blocks of 832 surgically removed lymph nodes and carcinoma tissues from 52 lymph node negative cases comfirmed by routine pathology were re examined by immunohistochemical staining using monoclonal anti EMA and anti nm23 H1 respectively. Results Micrometastasis were observed in 12 of the 52 patients (23.0%) and in 34 of the 832 lymph nodes ( 4.1% ). The positive rate of micrometastasis that in the tumor larger than 2.0cm or poorly differentiated was significantly higher than in the tumor

Objective To measure the daily nursing workload by simplified therapeutic intervention scoring system and provide information for reasonable dynamic management of nursing manpower and improving nursing service satisfaction of patients in elderly ICU.Methods 113 patients in elderly ICU were selected from July 2012 to June 2013.The Therapeutic Intervention Scoring System 28(TISS-28) was used to measure the nursing workload,reasonably arranged the nursing staff according to the daily total nursing workload.The average daily working time and service satisfaction were compared before and after the application of dynamic management of nursing manpower.Results After the application of dynamic management of nursing manpower,the average daily working time of nurses decreased,satisfactory degree of patients with nursing service increased,and satisfactory degree of medical workers with nursing manpower management also increased.Conclusions Measurement of nursing workload by TISS-28 can provide the basis for the dynamic management of nursing manpower in elderly ICU and improve satisfaction degree of medical workers.

Objective To research the 50% effective anesthetic volume ( EAV50) of 0.5% ropivacaine in nerve stimulator-guided vertical infraclavicular brachial plexus block. Methods Thirty patients scheduled for forearm or hand surgery were blocked using 0. 5% ropivacaine in nerve stimulator-guided vertical infraclavicular brachial plexus block. The EAV50, which is the anesthetic volume corresponding to 50% success and 50% failure was determined by up-and-down sequential test. The starting dose of 0. 5% ropivacaine was 0. 55ml/kg. Block failure resulted in a dose increase 110% , and block success in a reduction 110%. The sensory and motor blockade were accessed at 5- min intervals (up to 60 min). Results In nerve stimulator-guided vertical infraclavicular brachial plexus block, EAV50 for 0.5% ropivacaine was 0.417ml/kg. In up-and-down sequential test, there were significantly different in the block success rates of lateral, medial and posterior cord ( P <0.01). Conclusion In nerve stimulator-guided vertical infraclavicular brachial plexus block, enough anesthetic volume must be given to increase block success rates of all the cords of brachial plexus, and EAV50 for 0. 5% ropivacaine was 0.417ml/kg.

Objective To systematically investigate the efficacy and safety of sublingual immunotherapy( SLIT) in the treatment of a-dults with seasonal allergic rhinitis( SAR) .Methods Literature was retrieved online in CNKI,CBM,VIP,Wanfang data,PubMed,EMBase, Medline,Cochrane Library,et al.After screening literature,data collection and assessment quality,randomized controlled trials relevant to our study were selected independently based on inclusion and exclusion criteria by two researchers.Statistical analyses were conducted by RevMan 5.2 software.Results A total of 13 RCTs were enrolled.The meta-analysis revealed that SLIT provided a significant improvement in aspect of reducing Symptom Scores(SS) and Medication Scores (MS)of adults with SAR,the difference had statistical significance(P<0.000 01). Compared to placebo,SLIT could increase the rate of adverse events( AEs) in the treatment of adults with SAR compared to placebo.The fre-quently reported AEs during clinical trials were oral pruritus,tongue edema,ear pruritus,throat irritation,et al.Conclusion Sublingual im-munotherapy could improve the symptoms significantly and reduce the SS and MS in the treatment of adults with SAR.And its safety could be well tolerated.

Objective To study MR findings in 20 children aged from 10 months to 14 years with mitochondrial encephalomyopathy.Methods MRI evaluations were done in 20 children with mitochondrial encephalomyopathy proved by muscle biopsy and biochemical laboratory examinations.Results Brain parenchymal lesions in all cases were low signal intensity on T 1-weighted and high signal intensity on T 2-weighted images.Brain atrophy was showed in different degrees in 8 children.18 patients had involvement of gray matter,10 had only the deep gray matter involved and 4 cases had both the deep gray matter and the cerebral cortex involved simultaneously.4 patients showed deep gray matter abnormalities and cerebral infarction with involvement of cortex and subcortical white matter.2 patients had exclusively involvement of white matter,which were nonspecific white matter changes of the trigonal area.Conclusion MRI findings in mitochondrial encephalomyopathy are varied when gray matter especially deep gray matter involved,brain atrophy,untypical infarction and involvement of peripheral white matter are showed on MR,and associated with a variety of neuromuscular symptoms in children mitochondrial encephalomyopathy should be consider.
