Ocular Beh(c)et disease,which usually presents as panuveitis,with characteristic of vision impairment and relapse,is one of the most refractory uveitis entities.Usually,one or more conventional immunosuppressive agents,such as glucocorticoid,ciclosporin,chlorambucil,cyclophosphamide,etc,are needed in disease management.However,long-term use of immunosuppressive agents would result in severe adverse effects.New biologics,such as interferon,antitumor necrosis factor agents,interleukin or its receptor antagonists,provide new therapeutic approaches to the treatment for this disease.This paper reviewed the conventional therapies and biologics applied in ocular Beh(c)et disease.

Objective To investigate the effects of long-term consumption of Fallopia multiflora on mouse hematopoietic system.Methods Forty 10-month old female C57BL/6J mice were equally divided into two groups at random, the control group fed with normal food , and the experimental group , given food with added Fallopia multiflora. After 10 month, the mice were sacrificed, and the peripheral blood, spleen, thymus and bone marrow cells were examined by flow cytometry.Results In the mice fed with Fallopia multiflora, the percentage of B cells in the spleen and CD 4 +cells in the thymus were increased , and CD8 + cells in the thymus and bone marrow hematopoietic stem cells were decreased , among the bone marrow cells , G0 cells were increased , but G1 and G2/S/M cells decreased .Conclusions Long-term proper consumption of Fallopia multiflora can delay the ageing of the hematopoietic system , and sustain its stability.

AIM: To observe the effect of L arginine on blood pressure (BP) in stress rats. METHODS: Thirty rats were divided into three groups. L ARG+stress group: L arginine was added in drinking water and electric stimulus were given intermittently in rat foot plate for 15 days; stress group: electric stimulus was given as above; control group: no stress. The BP levels of tail artery were measured per two days, and the concentrations of nitric oxide (NO) of plasma were detected on 15th day. RESULTS: There were significantly differences on BP between control group and stress group in the 9th,11th,13th,15th day(P

Objective To determine the clinical manifestation,pathologic behavior,therapy and related factors of rare aggressive fibromatosis.Methods Canceration from aggressive fibromatosis to fibrosarcoma in one case of aggressive fibromatosis was analyzed and relevant literatures were reviewed.Results Aggressive fibromatosis was a benign or semimaligrant,non-metastatic proliferations of fibrous tissue that infiltrated surrounding tissues and tended to recur after surgical resection.Pathology showed fibroblastic monoconal proliferation between the cellular center and the collagen periphery.Electron microscope showed an abundant collagen network enclosing a pelymorphous cellular proliferation.Immunohistochemistry defined vimentin and actin positive desmoid tumors.Complete surgical excision was a chief treatment.Several operations were needed in most cases.Recurrence rates may be as high as 10%～70%.Chemotherapy and radiotherapy may be used together with surgery in recurrence or unsatisfactory surgical margin.The disease recurred after operation and one radiation therapy,reoperation and pathology showed fibrosarcoma.Conclusion Aggressive fibromatosis is a rare benign,non-metastatic proliferation tumour of fibrous tissue with a tendency of local recurrent after surgical resection.The cornerstone of therapy is surgery.Radiation therapy and chemotherapy can be used as adjuvant therapy.It is scarce that aggressive fibromatosis cancerates to fibrosarcoma.Maybe surgical stimulus and radiation therapy are the main factors to promote it to cancerate.

Objective: To observe the effects of pentazocine on emergence agitation.Methods: Totally 60 patients with scheduled upper limb operation with general anesthesia were randomly divided into two groups (n =30).Group Ⅰ was given pentazocine 0.25 mg·kg-1 (diluted to 10ml) and group Ⅱ was treated with 0.9% sodium chloride (10 ml) and both were with slow intravenous injection above 3 min before the surgical stitching.BP and HR were recorded and compared before the induction (T 0), before the extubation (T 1) ,at the extubation (T 2), and 5, 10 and in 15 minutes after the extubation (T 3 , T 4 and T 5).The time of recovery, time of extubation and agitation scores in 15 min after the extubation were recorded and compared, and nausea and vomiting were observed as well in both groups.Results: Compared with those in group Ⅰ, HR and BP in group Ⅱ were significantly higher (P＜0.05) at T 3 , T 4 and T 5.There were no significant differences in the breathing recovery time and awakening time between the groups (P＞0.05).The restlessness score in group Ⅰ was significantly lower than that in groupⅡ (P＜0.05).The incidence and degree of postoperative nausea and vomiting in groupⅠ were significantly higher than those in group Ⅱ (P＜0.05).Conclusion: Pentazocine (0.25 mg·kg-1) given before stitching can maintain stable circulation, reduce emergence agitation and protect the safety of patients.

Objective: To explore levels of salivary IgA, lysozyme, lactate dehydrogenase, alkaline phosphatase and total proteins in unstimulated (UWS) and stimulated (SWS) whole saliva of caries-free children. Methods: 94 caries-free children, aged from 42 to 54 months, were recruited from urban kindergartens in Beijing. 2 ml UWS and 2 ml SWS were collected from each child to measure salivary IgA, lysozyme, lactate dehydrogenase, alkaline phosphatase and total proteins. Results:1) There were no differences in salivary proteins between boys and girls in both UWS and SWS, except total proteins. In UWS, the concentration of total proteins in girls was lower than that in boys (P0.05). 2) The concentration of IgA in SWS was significantly lower than that in UWS (P0.05). Conclusion:In 3-to 4-year old children, the protein composition in stimulated whole saliva is different from that in unstimulated whole saliva, and it is also different between genders. Therefore, it is more reliable to measure salivary proteins in both UWS and SWS when studying saliva of children.

Objectve To investigate the correlation between vertebral artery hypoplasia (VAH) and posterior circulation ischemic stroke (PCIS).Methods The patients who were diagnose as ischemic cerebral stroke and underwent brain magnetic resonance imaging and cervical three-dimensional contrast-enhanced magnetic resonance angiography from March 2012 to March 2014 were enrolled.VAH was defined as vertebral artery diameter ＜ 2 mm and thin or did not develop.They were divided into either an anterior circulation ischemic stroke (ACIS) group or a PCIS group according to the sites of disease.The clinical and imaging data were compared.Results A total of 137 patients were enrolled,including 96 patients (70.07％) with ACIS and 41 (29.93％) with PCIS.Thirty-seven patients were (27.01％) diagnosed as VAH,including 13 on the left and 24 on the right; 14 females and 23 males.The detection rate of females (29.17％) was higher than that of males (25.84％),but the difference was not statistically significant (x2 =0.175; P =0.676).There were significant differences in TOAST classificanon (x2 =6.710; P =0.035),combined with ischemic heart disease (14.6％ vs.61.5％ ; x2 =25.262,P ＜ 0.001) and VAH (58.5％ vs.13.5％ ; x2 =9.505,P ＜0.001) between the PCIS group and the ACIS group.Multivariable logistic regression analysis showed that VAH was independently correlated with PCIS (odds ratio 10.788,95％ confidence interval 3.863-30.131; P ＜ 0.001),and combined with ischemic heart disease was independently correlated with ACIS (odds ratio 0.082,95％ confidence interval 0.024-0.278; P ＜ 0.001).Conclusions VAH is not rare in patients with ischemic stroke.It may promote the occurrence of PCIS.

Objective To investigate the change regulation of the serum ferritin level and its correlation with the clinical outcomes.Methods The patients with spontaneous intracerebral hemorrhage were enrolled.Their clinical data were collected.The serum ferritin levels were detected within 24 h after admission and on day 3,7,and 14,respectively.The modified Rankin Scale (mRS) were used to evaluate the clinical outcomes at day 90 after onset.mRS 0 to 2 was defined as good outcome and ＞ 2 was defined as poor outcome.Results A total of 32 patients with spontaneous intracerebral hemorrhage were enrolled,including 18 in the good outcome group and 14 in the poor outcome group.There were significant differences in age (66.33 ±12.57 years vs.76.50 ±6.55 years;t =-2.908,P =0.007),baseline National Institutes of Health Stroke Scale (NIHSS) scores (median [interquartile range];9.50 [4.75-11.25] vs.15.00 [11-20];Z=-3.499;P=0.001),diastolic blood pressure (82.16± 13.79 mmHg vs.94.76± 12.17mmHg,1 mmHg=0.133 kPa);t=-1.145,P=0.045),amount of bleeding (4.50 [2.75-9.00] mlvs.11.00 [7.50-15.00] ml;Z=-2.613,P=0.008],blood glucose (5.82±0.87 mmoFL vs.7.09±1.72 mmoFL;t =-2.548,P =0.020),and white blood cell count ([7.26 ± 2.36] × 109/L vs.[10.94 ±5.83] × 109/L;t =-2.440,P =0.021) between the good outcome group and the poor outcome group.The serum ferritin levels of the good outcome group were 139.81 ± 98.50 μg/L,181.77 ± 97.29 μg/L,198.17 ±96.63 μg/L,and 159.59 ±72.43 μg/L,respectively,within 24 h on admission and at day 3,7,and 14.There were no significant differences at each time point (F=1.397,P =0.251),and those of the poor outcome group were 226.07 ± 119.22 μg/L,297.36 ± 81.48 μg/L,305.45 ± 97.05 μg/L,and 307.74 ± 82.54 μg/L,respectively,and they increased progressively over time (F =4.245,P =0.044);at each time point,the good outcome group was significantly lower than the poor outcome group (within 24 hon admission:t =-2.242,P=0.033;at 3 days after onset:t =-3.234,P =0.003;at 7 days after onset:t =-3.149,P =0.004;at 14 days after onset:t =-3.628,P =0.001).Multivariate logistic regression analysis showed that the serum ferritin level within 24 h on admission (odds ratio 1.048,95％ confilence interval 1.004-1.095;P=0.034)and baseline NIHSS score (odds ratio 1.021,95％ confidence interval 1.004-1.039;P =0.016) were the independent risk factors for affecting the outcomes in patients with acute intracerebral hemorrhage.Conclusions The serum ferritin level increases in the poor-outcome patients with acute intracerebral hemorrhage.The increased serum ferritin level is an independent risk factor for poor outcome in patients with acute intracerebral hemorrhage.

Objective To investigate the effect of repetitive transcranial stimulation (rTMS) on learning and memory and on the neuron and synapse ultrastructures of the CA3 region of the hippocampus.Methods Forty Sprague-Dawley (SD) rats were randomly divided into 4 groups (n =l0 in each group):a normal control group,a depression group,an rTMS group and a sham group.Unpredictable mild stress was used to establish depression models in the rats of the latter3 groups.The sucrose water consumption test and open-field test were used to evaluate any depressive behavior of each group.The rTMS group rats were given 15 Hz rTMS for 21 days while the sham group received sham stimulation.The orientational navigation and spatial probe tests were performed on each group using a Morris water maze to evaluate their learning and memory abilities.In addition,changes in the ultrastructure of the CA3 region of the hippocampus were detected using transmission electron microscopy.Results The modelling induced significant differences in the sucrose water consumption test results and in horizontal and vertical behavior in the open-field tests.Escape latency and spatial probe time were significantly different between the rTMS group and the sham and depression groups.There was no significant difference in the behavioral indexes between the depression group and the sham group.Electron microscopy showed pathological changes in the ultrastructures of the neurons and synapses in the CA3 region of the hippocampus among the depression group,while in the rTMS group those ultrastructures tended to be basically normal.Conclusion rTMS can improve learning and memory during depression,at least in rats.A possible mechanism is that rTMS can induce changes in the ultrastructures of neurons and synapses in the CA3 region of the hippocampus.
