Objective To estimate the value of neck circumference in diagnosis of metabolic syndrome. Methods We analyzed the neck circumference of 523 volunteers and the occurrence of metabolic syndrome among them. Then we updated and revalued their data after follow-up for 1.5 years, meanwhile, we evaulated the value of Body Mass Index (BMI) and neck circumference in predicting metabolic syndrome. Results The increase of neck circumference was closely related to the occurrence of metabolic syndrome , and this tendency continued in the follow-up. Compared with BMI , neck circumference was sensitive in identifying the patients of metabolic syndrome. Conclusion Neck circumference has great value in diagnosis and treatment of metabolic syndrome.

Objective To investigate the clinical characteristics of infectious diseases of CNS.Methods Inpatients treated in the second hospital of Hebei Medical University from 1996 to 2005 were subjected to retrospective study.Results During 10 years,the hospitalization number of infectious diseases of CNS was 3929.The proportion of inpatients with viral meningitis(encephalitis),cerebral cysticercosis,tuberculous meningitis(TBM),purulent meningitis(PM)and cryptococcal meningitis(CM) was 63.8%,17.4%,7.7%,0.7% respectively.The hospitalization number of viral meningitis (encephalitis),TBM,PM and CM in the 2001—2005 5-year period was 53.5%,21.3%,35.3%,and 77.3% higher than that of the 1996—2000 period.Whereas the hospitalization number of cerebral cysticercosis decreased by 32.4% than that of the last 5 years.The peak months of viral meningitis (encephalitis)in a year were July,August and September.The peak months of TBM in a year were April, May and June.The case fatality of viral meningitis(encephalitis),cerebral cysticercosis,TBM,PM and CM was 8.1%,6.9%,22.4%,12.9%,33.3% respectively.Conclusions In the past l0 years,the incidence of common infectious diseases of CNS has increased in Shijiazhuang except cerebral cysticercoids. Our vigilance should be improved and some effective measures should be adopted to keep away infectious diseases of CNS.

AIM:To investigate peripapillary vessel density and its relationship with other ocular parameters in highly myopic eyes with peripapillary intrachoroidal cavitation (PICC), and to analyze risk factors for PICC.METHODS:Cross-sectional study.A total of 35 highly myopic eyes with PICC, 40 highly myopic eyes without PICC and 35 normal eyes were included in this study.All participants underwent fundus photography and spectral-domain optical coherence tomography (SD-OCT).OCT angiography was also performed to image the retinal vasculature in the peripapillary areas of different sectors, including the radial peripapillary capillaries (RPC) and optic nerve head (ONH) layer.The difference of morphology changes in optic disc and peripapillary vessel density between these three groups were compared.Correlations between peripapillary vessel density and PICC and risk factors for the presence of PICC were analyzed.RESULTS: Significant differences were found among the three groups in spherical equivalent refraction (SER), best-corrected visual acuity (BCVA), axial length, peripapillary atrophy β-zone (β-PPA) area, retinal nerve fiber layer (RNFL) thickness and the presence of tilted optic disc, posterior staphyloma and myopic maculopathy (MMD) (P<0.05).There were significant differences among the three groups in the peripapillary vessel density both in RPC (54.34±5.58, 57.54±7.44, 64.42±3.50) and ONH (51.24±7.43, 52.75±9.96, 61.25±4.15) layers (P<0.001).In highly myopic eyes, vessel density was significantly lower in eyes with PICC than in those without in inferotemporal area both in the RPC (56.76±6.62,63.84±6.02,67.52±4.78) and ONH (56.47±5.79,60.38±4.72,64.18±4.37) layers.The vessel density was significantly correlated with the presence of MMD, β-PPA area and RNFL thickness in the RPC layer, whereas correlated with the presence of MMD, PICC and RNFL thickness in the ONH layer (P<0.05).Tilted optic disc and posterior staphyloma were independent risk factors for the presence of PICC (OR=8.007, 95%CI: 2.045-31.348;OR=7.558, 95%CI: 1.398-50.026).CONCLUSION:Highly myopic eyes with PICC had relatively lower peripapillary vessel densities, especially in the temporal area, than those without.Tilted optic disc and posterior staphyloma were independent risk factors for the presence of PICC.

Objective To evaluate the expression of RAR-? gene in cervical carcinoma cell lines SiHa,HeLa,C33A and Caski and to analyze the relation between their gene expression and the promoter methylation of RAR-? DNA.Methods The expression of mRNA and protein of RAR-? gene in the four cell lines were analyzed by RT-PCR,western blot and immunofluoreseence,respectively.Methylation specific PCR(MSP)was used to check whether there was methylation in the promoter of RAR-? gene.The demethylating agent 5-aza-2'-deoxycytidine(5-Aza-cdR)was used to treat methylated cell lines and the change of RAR-? gene methylation and RAR-? gene expression defects were observed.The cell proliferation was assayed with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method.Results The mRNA and protein expression levels of RAR-? in cell lines SiHa,HeLa,Caski and C33A were 0.25 ?0.08,0,0.60?0.19,3.12?0.92 and 0.23?0.07,0,0.14?0.05,0.68?0.21,respectively.The mRNA and protein expression of RAR-? in SiHa,HeLa and Caski cell lines were decreased or silenced, whereas its expression increased in C33A cell line.MSP method showed that there were RAR-? gene methylation in SiHa,HeLa and Caski cell lines,while there was no RAR-? gene methylation in C33A cell line.After treated with 5-Aza-cdR,the mRNA and protein expression levels of RAR-? in SiHa,HeLa, Caski and C33A cell lines were 1.82?0.59,2.13?0.62,1.67?0.43,2.95?0.89 and 0.69?0.21, 0.83?0.29,0.56?0.16,0.64?0.20 respectively.The mRNA and protein levels of RAR-? had a significant difference between before and after interference with 5-Aza-cdR in SiHa,Helm,and Caski cell lines(P0.05).The 5-Aza-cdR treatment could suppress cell proliferation.Conclusions The RAR-? gene expression defects play an important role in the carcinogenesis of cervical cancer.Aberrant methylation in promotor region of RAR-? gene may be an important mechanism for the loss of expression of RAR-? gene.
