Background Congenital fibrosis of extraocular muscles (CFEOM) affects patient' s appearance and quality of life,and no effective treatment for this disease is available.Imaging study is helpful for exploring the pathogenesis of CFEOM.Objective This study was to describe the characteristics of CFEOM associated with limb movement disorder using magnetic resonance imaging (MRI).Methods A family with CFEOM associated with limb movement disorder was investigated in Renmin Hospital of Wuhan University.Disease history was collected and the pedigree was investigated.Ophthalmologic examinations,including corrected visual acuity,refractive error,slitlamp examination,ophthalmoscopic examination,force of levator palpebrae superioris,ocular movement,eye position,forced duction test,and bell phenomenon examination,were performed.Ocular orbital and cranial MRI was performed in 4 CFEOM patients and 10 normal subjects to compare the structures of the extraocular muscles,motor nerve and cranium.Oral informed consent was obtained from each patient prior to any medical examination.Results A total of 1 1 members from 3 generations were investigated in this study,presenting with 4 cases of disease.The mode of inheritance of this family complied with the Mendelian autosomal dominant inheritance law.Clinical signs included disturbance of eye movement,deviation of eye position,ptosis,lack of Bell sign and positive reaction of passive pull test.In addition,unstable gait,improper body limb alignment,dysphasia and mental retardation were ohserved in 1 patient,which coincided with the diagnostic criteria of type 3 CFEOM.MRI results demonstrated that the levator palpebrae superioris,superior rectus and superior oblique muscle were clearly thinner,and the medial rectus,lateral rectus,inferior rectus muscle were thinning in the patients,showing significant differences in comparison with the normal controls(P<O.05).The oculomotor and abducens nerves became thinner and even absent in the patients.Cranial MRI showed that Ⅲ-3 in the pedigree with callosum was shorter than that of the normal controls,suggesting that patient suffered from corpus callosum hypoplasia.Meanwhile,cranial MRI indicated the presence of cerebellar hypoplasia and the expansion of the fourth ventricle.Conclusions MRI demonstrates consistent abnormalities of the oculomotor nerves and abducens nerves in the affected individuals in this CFEOM 3 family,and some affected members exhibit two types of central nervous system abnormalities-corpus callosum and cerebellar hypoplasia.These findings suggest that CFEOM 3 is primarily a neuronal disease.

INTRODUCTIONHepatitis B virus (HBV) infection is endemic in Asia. Good public knowledge on disease transmission is one way of controlling spread of HBV. We aimed to study the general knowledge on HBV among the general public in Singapore, which is moderately prevalent with HBV.
MATERIALS AND METHODSBefore conducting a public education seminar on liver diseases, a 16-point questionnaire survey was conducted among the participants. Misperceptions (if any) were identified, and factors associated with knowledge score were analysed by multivariate analysis.
RESULTSOne hundred and ninety-two subjects completed the questionnaire. The mean age was 52 years, 78 (41%) were male, 183 (95%) were Chinese, 17 (9%) were known hepatitis B carriers and 73 (38%) had completed college education. The mean knowledge score was 10.7 (out of a maximum of 16). Most misperceptions were in the category of HBV transmission. At multivariate analysis, having college education was the only independent factor associated with a high knowledge score.
CONCLUSIONAlthough HBV infection is moderately prevalent in Singapore, many misperceptions existed among the general public, especially on the mode of transmission. Better education was related to better knowledge of HBV. Further public education should be targeted to clear the misperceptions identified, and be specifically targeted to the less educated.

OBJECTIVETo explore the metabolism-related risk factors of cholelithiasis among residents in Beijing.
METHODSThe clinical data including previous disease history, findings of physical examination, and results of cholecystosonography of 2270 patients with cholelithiasis identified in the Health Screening Center of Peking Union Medical College Hospital between August 2007 and August 2010 were retrospectively reviewed (the case group). Meanwhile, 4336 healthy individuals during the same period were randomly chosen as the control group.
RESULTSTotal cholesterol, triglyceride, low-density lipoprotein cholesterol, fasting blood glucose, body mass index, and systolic blood pressure were positively correlated with the incidence of cholelithiasis (P < 0.05), while high-density lipoprotein cholesterol was negatively correlated (P < 0.05). Diastolic blood pressure showed no association with cholelithiasis (P > 0.05).
CONCLUSIONCholelithiasis is resulted from multiple factors including elevated blood lipids, blood glucose, and systolic blood pressure among residents in Beijing.

This study was purposed to investigate the possibility of differentiating the acute promyelocytic leukemia (APL) cells into dendritic cells (DCs) induced by all-trans retinoic acid (ATRA) combined with classic cytokines so as to provide a new approach for development of APL-DC vaccine. The bone marrow mononuclear cells from a new diagnosed patient with APL and HL-60 cells were separately cultured in complete culture medium. The cells were treated by ATRA, GM-CSF, IL-4 and TNFalpha in experimental groups and no ATRA was added in control and blank control groups. The cell morphology was observed by light microscopy, the phenotypes of DCs were detected by flow cytometry, the level of IL-12 was measured by using ELISA, the mixed lymphocyte reaction (MLR) and effect of cytotoxic T-lymphocyte (CTL) were assayed by MTT method. The results indicated that in experiment groups, the cells had dendritic appearance and cytogenetic characteristics of APL; expression of CD1a, CD83, CD80, CD86, HLA-DR and CD1d as well as level of IL-12 obviously increased; the MLR and CTL effects were significant, but increase of CD1a expression in HL60-DCs did not show statistical difference from control and blank control groups. It is concluded that ATRA can successfully induce APL cells to differentiate into functionally mature DSs which obviously mediate MLR and CTL effects. The APL-DCs derived by ATRA can notably express CD1d that may activate CD1d-restricted NKT cells and promote proliferation of NRT cells. The exact mechanism of which should be further studied.

Objective To evaluate contrast-enhanced fluid-attenuated inversion recovery (FLAIR) imaging in the detection of leptomeningeal lesions.Methods Seventeen patients with a variety of leptomeningeal lesions were analyzed.The MRI protocol included un-enhanced and contrast-enhanced FLAIR images and contrast-enhanced T_1WI,Comparisons between contrast-enhanced FLAIR images and T_1WI and between un-enhanced and contrast-enhanced FLAIR images were made to determine which sequence better depicted the lesions.Results Leptomeningeal lesions showed as either diffusely or locally abnormal hyper-intensity along sulci or cistern on three sequences.Comparison between contrast-enhanced FLAIR and T_1WI showed that only contrast-enhanced FLAIR revealed the abnormalities in 7,both revealed the abnormalities but the former was superior in 2 ,and both were conspicuous in 7. In 1 patient of tuberculous meningitis,diffuse abnormalities of sulci were shown only on contrast-enhanced FLAIR, abnormalities of cisterns were shown on both sequences but the former was superior.Comparison between un- enhanced and contrast-enhanced FLAIR showed that only contrast-enhanced FLAIR revealed the abnormalities in 9,both revealed the abnormalities but the former was superior in 3,and both were conspicuous in 4. In 1 patient of tuberculous meningitis,abnormalities of cisterns were shown only on contrast-enhanced FLAIR,diffuseabnormalities of sulci were shown on both sequences but the former was superior.Conclusions Contrast-enhanced FLAIR images were superior to un-enhanced FLAIR images and contrast-enhanced T_1WI in the detection of leptomeningeal lesions. Contrast-enhanced FLAIR images are helpful and should be considered when findings on un-enhanced FLAIR images and/or contrast-enhanced T,WI are inconclusive.

objecfive To know and compare the intelligence level of children born in different time periods in regions with iodine deficiency disorders(IDD)in Liaoning province.Methods All 7-14 year-old children from ten schools were chosen as the subjects respectively from six villages in each of the six counties and in regions with iodine deficiency,who were respectively born at the initialization of iodinated salt supplying period(1978-1980);non-iodinated salt supplying period(1981-1990);recovery of supplied iodized salt period(1991-1995);universal iodized salt period(1996-2000),respectively.Intelligence quotient(IQ)was measured by Combined Ravens Test in China(CRT-C)and Combined Ravens Test-the Rural,in China,2nd edition(CRT-RC2).Results IQ of children during the non-iodized salt period(91.9±14.3)was significantly lower than the initial supply of iodized salt period(95.8±14.6,q=8.60,P<0.01),recovery of supplied iodized salt period(99.7±14.7)was significantly higher than the initial supply of iodized salt period, non-iodized salt sales period(q = 9.53, 18.13, all P < 0.01 ),universal salt iodization( 104.3 ± 14.9) was significantly higher than the initial supply of iodized salt period, non-iodized salt sales period, recovery of supplied salt iodization(q = 20.00,28.00,10.46, all P < 0.01). Children's rate of mental retardation (IQ≤69) was higher in non-iodinated salt supplying period (6.7%, 88/1314 ) than the initial supply of iodized salt (4.4%, 21/471, χ2 = 3.85, P < 0.05), recovery of supplied iodized salt period(3.3%,48/1470) was significantly lower than non-iodinzed salt supplying period (χ2 = 15.37, P < 0.01), universal salt iodization period(2.7%, 36/1344) was lower than the initial supply of iodized salt period(χ2 = 4.41, P < 0.05) and non-iodinzed salt supplying period(χ2 = 26.34, P < 0.01 ). The IQ and intelligent retarded rates in children born during the initial years of iodinated salt supplying period were not different. The IQ of the children during ten years of non-iodized salt supplying period fluctuated in a "∪" curve, while the intelligent retardation rates in a "∩" curve.The children born during the period of recovery supplied iodized salt increased their IQ and lowered the retardation rates year after year. The IQ of the children in universal iodized salt period kept on increasing while intelligent retarded rates reduced to the lowest level. Conclusions The intelligence level of children born in regions with IDD during non-iodized salt supplying period is remarkably lower than that of the beginning years of iodinated salt supplying period. The intelligence level of children born after universal iodized salt period is remarkably higher than that of the initial iodinated salt supplying period and recovery of supplied iodized salt period, respectively.

OBJECTIVESTo evaluate if the humoral immune response of hepatitis B DNA vaccine pVAX1-S2S could be enhanced by Talpha1 and/or IFNa expression plasmid co-inoculated.
METHODSThe following mammalian expression recombinant plasmids were constructed: the plasmid pVAX1-S2S expressing hepatitis B surface antigen S2S, the plasmid pVAX1-T/I co-expressing thymosin a and IFNalpha, the plasmid pVAX1-I/S2S co-expressing IFNalpha and S2S. These plasmids were inoculated intramuscularly into several BALB/c mice groups in different combinations. In the co-immunization group 1 (pVAX1-I/S2S), each mouse was inoculated with 100 microg of pVAX1-I/S2S; in the co-immunization group 2 (pVAX1-S2S) each mouse was co-inoculated with pVAX1-S2S and 50 microg of pVAX1-TI; in the control group each mouse was inoculated with 100 microg of pVAX1-S2S. All the immunizations were boosted at 2 and 4 week intervals; then the serum samples were collected to detect the anti-HBs and anti-preS2 strengths.
RESULTS3, 5 and 8 weeks after the first inoculation, the positive rates of anti-HBs were 12.5%, 12.5%, 62.5% respectively in the co-immunization group 1 and 25%, 50%, 50% in the co-immunization group 2, while those in the control group were 0, 25%, 37.5%. The titers of anti-preS2 in co-immunization group 2 was 5 times higher than those in the other two groups.
CONCLUSIONThe data shows that Talpha1 and/or IFNalpha expression plasmid co-inoculated with pVAX1-S2S might act as an adjuvant to enhance the humoral immune response induced by pVAX1-S2S.
