Hemophagocytic syndrome is a dangerous disease,with rapid progression and high mortality,which can be divided into primary and secondary hemophagocytic syndrome.This article reviews the research progress on the diagnosis of hemophagocytic syndrome in recent years.

Objective: To observe the influence of treatment with combiration of sodium ferulate and(astragalus) injection(黄芪注射液) on changes of hemorrheology and renal function in patients with early(diabetic) nephropathy(DN).Methods: One hundred and forty patients with early DN were(randomly) divided into two groups.The control group(n=70) was treated with conventional therapy for (diabetes) and diet(control) method,while the treatment group(n=70) was treated with sodium ferulate(combined) with(astragalus) injection additionally.The therapeutic course was 3 weeks.Results: In the(treatment) group,the hemorrheological parameters were(significantly) decreased(P

AIM: To quantify cyclooxygenase - 2 (COX - 2) mRNA in carcinoma of larynx and evaluate the correlation between the quantity of COX - 2 mRNA and clinical staging or histological grade. METHODS: The expression of COX - 2mRNA in 30 cases of carcinoma of larynx tissue and adjacent non - cancerous tissues were evaluated by PCR, which includes a fluorescence dye , SYBR green Ⅰ , and the sequence specific primer. The GAPDH was used as control. RESULTS: The specificity of products was proved to be COX - 2 and GAPDH by the analysis of the melting curve of the amplified products and agarose gel electrophoresis. The expression of COX - 2 mRNA was detected in all cancerous tissues of 30 patients (100%), but only in 12 adjacent non - cancerous tissues of 30 patients (40%). The NCOX value of carcinoma of larynx tissue and adjacent non - cancerous tissues was 16.54 ± 13.27 and 9.24 ± 6.91, respectively, and the expression levels of COX- 2 mRNA elevated significantly in laryngeal squamous cell carcinoma tissue and there were significant correlation between the expression levels of COX - 2mRNA and clinical stage or histological grade. CONCLUSION: The expression of COX - 2 mRNA in carcinoma of larynx can be determined by real - time PCR technique. An increase in COX - 2 mRNA may be associated with carcinogenesis of carcinoma of larynx, and it may be useful as a biomarker in laryngeal cancer.

The inhibitory effects of two kinds of selective cyclooxygenase-2 inhibitors on the proliferation of human carcinoma of larynx Hep-2 in vitro and their corresponding mechanisms were investigated. Hep-2 cells were cultured with two kinds of selective cyclooxygenase-2 inhibitors (Sc-58125 and Celecoxib) at various concentrations for 24 h. Morphological changes were observed under the phase microscopy and the growth suppression was detected by using MTT colorimetric assay. Apoptotic DNA fragments were observed by agarose gel electrophoresis, and the cell cycle and apoptotic rate were detected by flow cytometry (FCM) respectively. Hep-2 cells became rounded and detached from the culture dish after being treated with Celecoxib for 24 h, however, they remained morphologically unchanged with Sc-58125. Sc-58125 could increase G2 phase cells, whereas, Celecoxib rose G1 phase cells. Both of the two effects were dose-dependent. Moreover, the Hep-2 cells cultured with 50 micromol/L and 100 micromol/L Celecoxib showed obvious apoptosis, with the nuclear DNA of cells exhibiting characteristic DNA ladder. So Sc-58125 could inhibit the proliferation of Hep-2 cells by altering the G2 phase cells. However, Celecoxib had the same effect by changing the G1 phase cells and inducing apoptosis at higher concentration.

As a vital part of human body, the brain executes junior and senior function through coordination and interaction of different functional regions. Modern scientific research showed that there were many human brain functional networks in the resting-state. The resting-state functional magnetic resonance imaging technology, which was getting more and more mature, taking opportunities for brain functional networks and was widely used in nervous and mental diseases, providing new methods and ideas for the diagnosis and assessment of nervous and mental diseases. This paper focused on the brain mechanism research methods based on resting-state networks and its application in nervous and mental diseases.

Objective To study the expression and pathologic significance of CD147,cyclophilin A (CyPA)and cyclophilin B(CyPB)in psoriatic lesions.Methods Immunohistochemical method was ap- plied to detect the expression of CD147,CyPA and CyPB in skin specimens of 15 patients with psoriasis pustulosa(PP),20 patients with progressive psoriasis vulgaris(PPV),and 20 patients with inactive psori- asis vulgaris(IPV).Immunoreactivity intensity distribution index(IRIDI)was calculated to assess the expres- sion intensity of CD147,CyPA and CyPB.Results CD147,CyPA and CyPB were detected in all speci- mens.The IRIDI scores of CD147 and CyPA were significantly higher in keratinocytes of psoriatic lesions than in those of the control specimens(all P0.05).The IRIDI score of CyPB in T lymphocytes of PP lesions was significantly elevated than that in PPV lesions,which was in turn higher than that in IPV lesions(all P0.05).Conclusion CD147,CyPA and CyPB may play a role in the occurrence and development of psoriasis.

A 53-year-old man presented with prunosus nodules and plaques on the trunk and extremities for half a month and with periorbital swelling for 4 days.Hematological examination in a local hospital showed thrombocytopenia,and pulsed corticosteroid therapy did not work.On physical examination,there were splenomegaly and multiple enlarged superficial lymphnodes.Serum calcium and 1-lactate dehydrogenase (LDH)were increased to 3.12 mmol/L and 853 U/L,respectively.Serum immunofixation electrophoresis evidenced the presence of a monoclonal immunoglobulin IgM (κ chain).Positron emission tomography (PET-CT) showed abnormal uptake in multiple lymph nodes,back wall of the pharynx,and spleen.The biopsy of a nodule in the neck revealed a diffuse infiltration of numerous atypical lymphoid cells in the subcutaneous fat tissue,which were medium-sized with round nuclei,obvious nucleoli and karyokinesis, Immunophenotyping of the abnormal lymphocytes indicated positive reactions for L26,CD79a,Bcl-2,cyclin D1,multiple myeloma oncogene 1 (partly),Ki-67 (＞80％),but negative for CD5,CD21,CD23,CD38,CD3,CD10,Bcl-6,CD45RO,terminal deoxynucleotidyl transferase (TdT),myeloperoxidase (MPO),CD30,anaplastic lymphoma kinase (ALK),CD117,or CD34.Fluorescence in situ hybridization (FISH) revealed the presence of a fusion gene (t(11:14) CCND1/IGH) in the abnormal lymphocytes.Based on the above findings,the diagnosis was made as blastoid mantle cell lymphoma with skin and periorbital involvement complicated by hypercalcemia.After treatment with rituximab injection,cyclophosphamide,vincristine,doxorubicin,dexamethasone,and intermittent treatment with intravenous high dose of methotrexate and cytarabine (R-Hyper-CVAD),serum calcium returned to a normal level three days later,and the patient made a quick and excellent recovery on the 6th day,with the regression of skin lesions and poriorbital swelling.Unfortunately,the patient eventually died of severe pulmonary infection one month later.

ObjectiveTo explore the relationship between the changes of neuro-electrophysiology and prognosis in children with Guillain-Barr? syndrome(GBS).MethodsThirty-eight children with GBS were divided into group A(rapid recovery,n=16) and group B(slow recovery,n=22) according to the time required for podosoma motor function recovery,at the same time,they were divided into the better prognosis group(n=22) and the worse prognosis group(n=16),for analyzing the difference between group A and B in terms of age,preceding infections,maximal Hughes grades and neuro-electrophysiology including motor conduction velocity(MCV),distal complex muscle action potential(dCMAP) and F wave,and investigating the related factors with the prognosis of GBS.Results1.MCV of tibial nerve was(40.2?2.53) m/s and(33.4?2.46) m/s in group A and group B,respectively;MCV of peroneal nerve was(45.2?3.23) m/s and(38.3?2.16) m/s in group A and group B,respectively,and the difference between group A and group B was significant(Pa0.05);abnormal rate of F wave(68.42%) was higher than abnormal rate of MCV(42.11%) and dCMAP(42.11%)(Pa
