Objective: To compare the expression levels of FOXP3 mRNA in the peripheral blood mononuclear cells(PBMC) of hepatitis B patients and healthy persons.Methods: Real-time fluorescence relative quantitative RT-PCR was used to determine the FOXP3 mRNA levels in the PBMCs from 25 patients with chronic hepatitis B and 11 healthy subjects.Results:The FOXP3 mRNA levels were significantly higher in the hepatitis B patients than in the normal subjects(P0.05).Conclusion: The high expression of FOXP3 might be an important factor for the persistence of HBV infection.

Thyroid papillary carcinoma harbors higher rate of lymph node metastasis, so neck dissection is an important part of the treatment. Due to better prognosis, attention to postoperative function and appearance of the patients increased. Low-collar incision with cervical sensory nerve plexus preservation modiifed neck dissection can improve appearance and function in postoperative patients and is gradually applied in clinic. This review mainly examines the thoroughness and safety of this new neck dissection in thyroid papillary carcinoma patients.

Background Retinopathy of prematurity (ROP) causes blindness due to retinal vasculopathy caused by abnormal oxygen dynamics.Studies have clarified the pivotal role of vascular endothelial growth factor (VEGF) in the development of ROP,while the studies on the role of VEGF receptor (VEGFR) in ROP are fewer.Objective This study was to evaluate the relationship between the expressions of VEGFR-1 and VEGFR-2 in retina and post-birth time in the mice with oxygen-induced retinopathy (OIR).Methods Sixty 7-day-old (P7) SPF C57BL/6J mice together with lactating female mice were fed in the environment with (75±2)％ oxygen concentration for 5 days and then returned to normal air to establish OIR models,and other 60 matched mice were kept in normal air environment as the control group.At P8,P11,P12,P13,P14,and P17,both eyes of each mouse were enucleated to prepare the retinal sections.Retinal blood vessels were examined by hematoxylin and eosin stain under the light microscope.Real-time fluorescence quantitative PCR and immunohistochemistry were used to detect the expressions of VEGFR1 mRNA and VEGFR2 mRNA and their proteins in mouse retinas,respectively.The use and care of the animals complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results Many vascular endothelial cell nucleus broke through the internal limiting membrane were seen with disorganized cell proliferation under the internal limiting membrane and retinal neovascularization bud in the P13,P14 and P18 mice in the OIR group,but no similar manifestation was found in the mice of the normal control group.The relative expression values of VEGFR-1 mRNA in retinas were significantly higher only in P12,P13,P14 and P18 mice in the OIR group than those in the normal control group (P=0.046,0.000,0.000,0.042),but the expression values of VEGFR-2 mRNA were all increased in the retinas of P8,P11,P12,P13,P14 and P18 mice in the OIR group,showing significant differences in comparison with the normal control group (all at P=0.000).No considerable difference was found in the expression level of VEGFR-1 protein in P8,P11,P12,P13,P14 and P18 mice between the two groups (M=50.00,36.00,41.00,31.00,28.00,36.00,all at P＞ 0.05).The expression levels of VEGFR-2 protein in retinas of P8 and P11 were close between the two groups (all at P＞0.05).Gradually attenuated expressions were seen in VEGFR-2 protein in P12,P13 mice of the normal control group,however,the expressions were enhanced in the OIR group,with significant differences between the two groups (all at P＜0.01).Enhanced expressions of VEGFR-2 protein were found in P14 mice in both groups,but stronger expressions were in the OIR group (P＜0.01).The positive response of the expression of VEGFR-2 protein was weaker in P18 mice in the normal control group but peaked in the OIR group,showing significant difference between them (M=20.11,P＜0.01).Conclusions VEGFR participates in the neovascularization of OIR mouse,and the effect of VEGFR-2 is stronger than that of VEGFR-1 in the development of OIR neovascularization.

Background Neovascular diseases such as retinopathy of prematurity often leads to irreversible vision loss.The study on oxidative damage mechanism is becoming more and more important.Whether brain derived neurotrophic factor (BNDF) has protection to retinal ganglion cells(RGCs) has few research reports.Objective The study was to investigate the expression changes of BDNFin mouse retinas of oxygen-induced retinopathy (OIR).Methods Thirty SPF C57BL/6J immature rats were divided into OIR group and normal control group and to fifteen rats for each group.OIR models were established by raising 7-day-old (P7) mice together with maternal mouse in (75±3) ％ oxygen environment for 5 days and then returned to the normal air environment,and the mice of the normal control group were raised in the normal air environment.The P17 mice were sacrificed for retinal histopathological examination by hematoxylin and eosin staining, and the number of vascular endothelial cell nucleus extending the inner limiting membrane was counted.Whole retinal mounts were prepared after fluorescein isothiacyanate-dextran (FITC-dextran) (9 ml/kg) was retrosorbitally injected,and the distribution of retinal vessels was observed in P17 mice.The relative expression levels of BNDF in retinas were detected in P13, P15, P17 mice, and the results were compared between the normal control group and the OIR group.Results Histopathological examination showed that retinal inner limiting membrane was smooth in the normal control group, but a lots of vascular endothelial cell nucleus extending the inner limiting membrane were seen under the optical microscope in the OIR group.The number of the vascular endothelial cell nucleus extending the inner limiting membrane was 1.70±0.68 in the normal group and 45.3±3.13 in the OIR group, showing significant difference between them (t =86.5, P =0.00).Whole retinal mount revealed that normal retinal vessels and network-like capillaries were exhibited in the mice in the normal group, while tortuous vessels,capillary loss and non-perfusion areas were revealed in the OIR group on the whole retina mounts.The relative expressing levels of BDNF in retinas were 263.992±9.451 and 218.432±9.710 in P15 and P17 mice in the OIR group,which were significantly higher than 230.324±7.779 and 115.846±7.305 in the normal control group (t=14.2,42.3 ,P＜0.05).Conclusions OIR can be inhibited by increasing the expression of BNDF.

BACKGROUND:Ankylosing spondylitis is an autoimmune disease involved in chronic systemic inflammation. Tumor necrosis factor and interleukin-6 levels increased in patients with ankylosing spondylitis. Inflammatory factors such as tumor necrosis factor and interleukin-6 can suppress CD36 expression in monocytes. OBJECTIVE: To analyze the correlation between CD36 expression in monocytes and ankylosing spondylitis. METHODS:A total of 84 newly diagnosed ankylosing spondylitis patients and 111 healthy individuals were included in this study. CD36 expressions in monocytes in ankylosing spondylitis patients and healthy individuals were tested using flow cytometer; meanwhile, biochemistry, immunology, routine blood examination and related inflammatory markers were determined between the two groups. RESULTS AND CONCLUSION:Results of baseline data in both groups demonstrated that CD36 fluorescence intensity in monocytes was significantly lower in patients with ankylosing spondylitis compared with healthy controls (P < 0.01). CD36 fluorescence intensity in monocytes was negatively correlated with C-reactive protein, erythrocyte sedimentation, interleukin-6 and tumor necrosis factor. In addition, CD36 fluorescence intensity in monocytes was negatively correlated with BASDAI score. Logistic regression analysis showed that erythrocyte sedimentation, interleukin-6, tumor necrosis factor and CD36 fluorescence intensity in monocytes were associated with ankylosing spondylitis, and risk factors for ankylosing spondylitis (P < 0.05). These findings confirm that inflammatory cytokine in patients with ankylosing spondylitis weakened the expression of CD36 in monocytes. There was a remarkable association between low expression of CD36 expression in monocytes and ankylosing spondylitis. CD36 expression of monocytes clinicaly may be considered to be an effective indicator to evaluate inflammation and disease activity in patients with ankylosing spondylitis.
