Objective To analyze the clinical characteristics of children infecting with Epstein -Barr virus. And in purpose to improve the knowledge of children infecting with Epstein -Barr virus.Methods We analyzed retrospectively to 97 cases of children which serodiagnosis of Epstein -Barr virus infectius in the aspects of the onset season,the age,clinical characteristics.And compared with complication group and no complication group in the aspects of the white cell count,neutrophils to white cell count ratio,lymphocyte to white cell count ratio and C -reactive protein.And contrasted the presence of statistical difference.Results The peak months were spring and summer(58 cases);Pre -school age was the peak age of EBV infectious(41 cases),and the rest respectively were toddlers age(33 cases),school age and youth(20 cases)and infant period(3 cases).The most frequently clinical manifestation respectively was pharyngitis,and other such as fever,lymphadenopathy,hepatosplenomegaly.There had no statistical difference in the two groups of complication group and no complication group in the aspects of the white cell count,neutrophils to white cell count ratio,lymphocyte to white cell count ratio and C -reactive protein(P >0.05).Conclusion The infant can suffer from infectious mononucleosis infect with EBV.Infectious mononucleosis have a variety of clinical manifestation,which always have some complications.The diognosis should combinate clini-cal manifestation with laberatory test.

Though parched Chinese herbal medicines contain less effective or index components, their pharmacological actions do not reduce or even become improved to some extent. However, the current studies related to material basis could not explain the changes in property, flavour and efficacy of parched Chinese herbal medicines. Meanwhile, due to the lack of objective and specific evaluation indexes, the quality evaluation could not reflect features of parched Chinese herbal pieces. Therefore, how to break the bottleneck for the studies on parched Chinese herbal pieces, make further innovation and conduct in-depth studies on the material basis of parched Chinese herbal medicines are common problems that medical scholars are facing. According to the findings in the previous studies, the author proposed to explain the material basis of parched Chinese herbal medicines by studying Maillard reaction and establish specific quality evaluation indexes according to the features of parched Chinese herbal pieces, and conducted relevant studies.

Objective To observe the imaging features of ultra-wide field short wave fundus autofluorescence (SW-FAF) in eyes with multiple evanescent white dot syndrome (MEWDS),and analysis the correspondence to conventional images.Methods It was a retrospective case series study.Thirteen patients (14 eyes) diagnosed with MEWDS were enrolled.There were 12 females and 1 male,aged from 22 to 57 years,mean age was 34.5 years.All the eyes underwent fundus color photography,optical coherence tomography (OCT) and ultra-wide field autofluorescence (FAF).Simultaneous fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in 6 eyes.The characteristic changes of SW-FAF in studied eyes were observed and compared with the images of FFA and ICGA.All the eyes were followed up every 1 to 2 weeks,with an average of 16.7 weeks.The characteristic images of SW-FAF and corresponding OCT were studied during follow up.Results MEWDS presented with numerous multiple hyper-autofluorescent spots,sized from 50-500 μm,with a vague boundary in ultra-wide field SW-FAF.These spots located mainly at the peripapillary area and the posterior pole with a confluent pattern.The lesions extended to the mid-peripheral retina as well and became more scattered.The distribution of the hyper-autofluorescent lesions in SW-FAF corresponded roughly to that of the greyish-white spots seen in color photograph and the hyper-fluorescent spots detected by FFA.It was consistent with the distribution of hypo-fluorescent spots in late-phase ICGA as well.But the number of the spot showed in FAF is much more than that in FFA,and slightly less than that in ICGA.The OCT scans through the hyper-autofluorescent lesions in SW-FAF showed impairment of outer retina.After the recovery,the hyper-autofluorescent spots disappeared with the outer retina structure repaired completely.Conclusions MEWDS presented with numerous multiple hyper-autofluorescent spots which located mainly at the peripapillary area in ultra-wide field SW-FAF.The distribution of the hyper-autofluorescent lesions in SW-FAF corresponded roughly to color photograph,FFA and ICGA in late-phase.The OCT scans through the hyper-autofluorescent lesions in SW-FAF showed impairment of outer retina.

Objective The color of the syphilis quality control material adopted by most detection institutes was the same with the detected serum sample and they were all colorless,transparent or light yellow.There were cases of wrong adding,missing adding or insufficient adding due to the color of quality control materials which was hard to distinguish with naked eyes.To avoid this phenomenon,a new method was established for the distinction of quality control materials.Methods A new method of syphilis quality control materials that had been improved three concentrations control materials:0.125,0.250 and 0.500 NCU/mL.The syphilis diagnostic kit that was created by Shanghai Kehua and Xiamen Yingke was adopted to conduct detection and compare results.Results The difference between stained quality control material and unstained quality control materials had no statistical significance (P>0.05).Two different reagents were used to detect quality control materials of different concentration for 20 times and the CV were 11.7 %-13.4% and 9.3 %-12.9 % respectively.Two different reagents were used to detect quality control materials of different concentration for 30 days and the CV range were 10.1 %-13.4 % and 8.08 %-12.8 %.Conclusion Citric yellow staining does not influence the properties of syphilis control materials and it can be used stably for a long time.It is suitable for clinical lab application and promotion.

AIM: To study the relationship between nitric oxide (NO) and gastric mucosal injury induced by reserpine in rats. METHODS: Sixteen healthy male Wistar rats were randomly divided into control group and experimental group (n=8). NO contents and malondialdehyde(MDA) contents in plasma, gastric mucosa of the rats were respectively determined with Cadmium-reduct plus Greiss and TBA; nitric oxide synthase in gastric walls of the rats were observed using NADPH-diaphorase histochemistry and quantitatively measured with image analyzer.RESULTS: The NO contents in both plasma and gastric mucosa of experimental group were significantly lower than that in control group (P

Objective To establish the Flow-FISH method for simultaneous detection of telornere length and cell differentiation antigen. Methods HL60, Raji, Molt4 cells were cultivated. Each step and the conditions of the Flow-FISH procedure were optimized, standardized and validated, then 14 acute leukemia patients were observed for the changes of telomere length combined with differentiation antigen after complete remission by the method. Results Cells were stained with Alexa Fluor(R) 647-labeled antibody. Anti-gen-anfibedy complexes were covalenfly cross-linked onto the cell membrane before telomere staining. Cells were hybridized with telomere-specific fluorescein isothiocyanate (FITC)-conjugated peptide nucleic acid (PNA) probes followed by being counterstained with propidium iodide(PI). Multicolor Flow-FISH was performed to analyze telomere length and differentiation antigen simultaneously. The patients showed longer telomere and lower antigen expression after complete remission. Conclusion The Flow-FISH method for simultaneous detection of telomere length and differentiation antigen was successfully established which might prove to be a promising means for leukemia research especially in those without special molecular markers.
