METHODS:Twenty-three cases of CT diagnosed single orbital cellulitis were examined by the visual evoked potentials. The affected eyes as observation group, and healthy eyes as control group. Comparative observation of visual evoked potential changes in amplitude and incubation period before, during and after the treatment. RESULTS: Compared with the control group, the observation group's visual evoked potential changes included reduced amplitude, extended incubation period. With the treatment progress, the observation group had gradual increase in amplitude, gradual reduction in incubation period.
CONCLUSlON: ln infantile orbital cellulitis, the use of visual evoked potentials is a simple, feasible and effective method to monitoring the visual function during the treatment.

Objective To explore the optimal concentration of heparin sodium solution, which to seal up intravenous indwelling needle, in patients with Ⅳ thrombocytopenia. Methods A total of 90 patients withⅣthrombocytopenia who required intravenous indwelling needle were randomly divided into three groups which namely A, B and C groups with 30 cases each. A group was sealed up the tube of intravenous indwelling needle with 1 ml heparin sodium solution of 6.25 U/ml, B group with 12.50 U/ml and C group with 25.00 U/ml. The change of the platelet count, plasma prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (Fbg) after extubation were observed in three groups and the incidence of blocking up and retention time were compared among three groups. Results The change of the platelet count, PT, APTT, Fbg were showed no statistical significance among three groups (P>0.05). The incidence of blocking up was 66.7%(22/30) in A group , 43.3%(13/30) in B group and 16.7%(5/30) in C group. They were showed statistical significance (χ2=15.000, P < 0.01). Retention time of tube above or equal to 3 days were observed respectively 13 person (43.3%,13/30) in A group, 21 cases(70.0%, 21/30) in B group, 25 patients(83.3%, 25/30) in C group. All above were showed statistical significance (χ2=11.000, P<0.01). Conclusions Heparin sodium 25.00 U/ml sealing up the tube of intravenous indwelling needle is safe in patient with Ⅳthrombocytopenia, which will reduce the ration of blocking tube and extend the life of tube.

Objective To evaluate the immunogenicity of an immune complexed hepatitis B vac-cine ( HBsAg-HBIG immune complexes , IC) in mouse and cynomolgus monkeys by using recombinant hepa-titis B vaccine ( Saccharomyces cerevisiae, HBsAg) as the control .Methods BALB/c mice were vaccinated with single dose of IC and single dose of HBsAg respectively and then serum samples were collected at differ -ent time points for the detection of dynamic anti-HBs by using ELISA .The serum anti-HBs titers in BALB/c mice vaccinated with different immunization strategies were also analyzed .ELISPOT assay was performed to detect the numbers of IFN-γSFC and IFN-γpositive rate in splenocytes of BALB/c mice intramuscularly im-munized with IC, HBsAg or standard hepatitis B vaccine at 5μg/mouse.ED50 was measured to evaluate the stability of IC.Twelve cynomolgus monkeys were equally divided into two groups and immunized with high dose (100 μg) and low dose (20 μg) of IC respectively and then , serum anti-HBs levels at different time points were detected .Results The serum anti-HBs titers in IC immunized group at different time points were higher than those immunized with HBsAg .Moreover, the anti-HBs titer induced by two doses of IC reached a level comparable to that elicited by three doses of HBsAg .ELISPOT assay showed that both the numbers of IFN-γSFC and IFN-γpositive rate were the highest in IC immunized group as compared with those immunized with HBsAg and standard hepatitis B vaccine .IC had a lower ED50 than HBsAg, indicating a good long term stability .Cynomolgus monkeys immunized with high or low dose of IC produced high levels of anti-HBs titer during a long time period .Conclusion IC has a higher immunogenicity inducing both hu-moral immunity and cellular immunity as compared with HBsAg or standard hepatitis B vaccine .

Objective To explore the relationship between thyroid hormone and colorectal adenomatous polyps (CAP) in middle-aged and elderly people.Methods We surveyed 3 042 middle-aged employees and retirees aged 45 years and over at a petrochemical enterprise of Ningbo.Their colonoscopic findings,body mass index,waist circumference and thyroid function were analyzed.Results Age and serum free triiodothyronine (FT3) of females with CAP were higher than those of the corresponding non-CAP group,so were age and waist circumference of males with CAP (P ＜ 0.05).Furthermore,these differences were statistically significant.The detection rate of CAP was significantly higher in males than in females (x2 =49.418,P ＜ 0.01).The detection rate of CAP was higher in females with higher levels of FT3.Multivariate unconditional logistic regression analyses showed the effects of thyroid hormone on the CAP differed by gender.Age and FT3 (OR =1.60,95％ CI:1.12-2.28,P =0.01) were correlated with CAP in females.However,only age and waist circumference were correlated with CAP in males.Conclusion Elevated FT3 may be a risk factor of CAP in elderly females.The detection rate of CAP may not be affected by FT3 levels in males.

Objective To investigate the clinical features and human papillomavims (HPV) types in 12 cases of HPV infection characterized by pseudocondyloma of vulvae. Methods Twelve women, who had a history of sexual behavior with non-spouses and presented with pseudocondyloma of vulvae, were included in this study. Tissue specimens were scraped or resected from the lesions of pseudocondyloma of vulvae. PCR-based reverse hybridization assay was performed to determine the genotypes of HPV. Results All the 12 specimens were HPV positive. The reverse hybridization assay generated 13 subgenotypes of HPV, including 3 low-risk genotypes (11, 42 and 43) and 10 high-risk genotypes (16, 18, 31, 33, 35, 39, 51, 52, 58 and 59). All the patients were found to be infected by at least one high-risk genotype. Of the 12 patients, 4 were infected by single type of HPV, 6 by 2 types of HPV, and 2 by 3 or 4 genotypes of HPV. Conclusion The patients characterized by pseudocondyloma of vulvae may suffer from high-risk HPV infection.
