BackgroundIt is important to measure the corneal curvature, anterior chamber depth (ACD) and axial length accurately for calculating IOL power. The interchange outcomes from different measuring methods and apparatus will cause unreliable IOL power. ObjectiveThe present study was to compare the differences of corneal curvature, anterior chamber depth (ACD) measured by IOLMaster and Orbscan Ⅱbefore and after laser in situ keratomileusis(LASIK) and further compare the axial length measured by IOLMaster and A-ultrasound. Methods One hundred and thirty eyes from 65 consecutive myopic patients before LASIK and 56 eyes of 28 cases with 1-month follow-up duration after LASIK in Henan Eye Institute were enrolled in this study. The K value, ACD between IOLMaster and Orbscan Ⅱ as well as results of axial length between IOLMaster and A-ultrasound were compared by using paired t test. The agreements of the measured values among IOLMaster, Orbscan Ⅱ and A-ultrasound were evaluated using Bland-Altman plot. ResultsBefore LASIK,the K value measured by IOLMaster,Orbscan Ⅱ were ( 43.32 ± 1.52 ) D and ( 42.99 ± 1.45 ) D respectively with the difference value of( 0. 33 ±0. 03 ) D, showing a significant difference(t=10. 380,P=0.000) and a positive relation between them(r=0.971,P=0.000). After LASIK,the K value measured by IOLMaster, Orbscan Ⅱwere(39. 02±2. 14) D and ( 38.91 ±2. 04) D with the difference value (0. 12±0. 33 ) D, presenting a significant differences between them (t =2.715, P =0.009). Bland-Altman plots indicated the disagreement in K value and uninterchangeable. Before LASIK, the ACD measured by IOLMaster,Orbscan Ⅱ and A-ultrasound were ( 3.72 ± 0. 22 ) mm, ( 3.69 ±0. 22 ) mm and ( 3.75± 0.27 )mm respectively and no significant differences were found between them (P ＞ 0. 05 ). Axial length measured by IOLMaster significantly prolonged in comparison with A-ultrasound(25.59± 1. 01 mm vs 25.22±0.99 mm ) , and the difference was( -0. 37 ±0. 30 ) mm, showing significant difference ( t =- 14. 098, P =0. 000 ) and positive correlation ( r =0. 954, P =0. 000 ). Axial length values measured by IOLMaster were ( 25.54 ± 1.05 ) mm in preoperation and ( 25.48 ± 1.01 ) mm in postoperation with the difference (0.052±0. 412)mm, showing statistically insignificant difference between them (t=0. 946,P=0. 348). ConclusionsKeratometries measured by IOLMaster,Orbscan Ⅱ are much more different. Therefore,these two methods are not recommended to use interchangely. ACD measured by IOLMaster,Orbscan Ⅱ and A ultrasound are proved to obtain the similar results and is clinically interchange. Axial length measured by IOLMaster is longer than that measured by A-ultrasound.

Objective:To find out the difference between children with attention-deficit/hyperactivity disorder and normal control,and the difference between boys and girls with ADHD in resting-state.Methods:There were 38 children with ADHD in this study including 31 boys and 7 girls,meanwhile,42 normal controls whose age and gen der were matched with children with ADHD were involved too,including 29 boys and 13 girls.Total scores of ADHD rating scale (ADHD-RS) were used to measure the severity of symptom for both ADHD and normal control.Magnetic resonance imaging was used to collect the resting-state functional magnetic resonance imaging data,and the fractional amplitude of low frequency fluctuation (fALFF) was measured for each child.Analysis of covariance (ANCOVA) was used to find out the difference between the group and the sex.Results:Children with ADHD showed a higher fALFF in the right medial superior frontal gyrus and right supplementary motor area,and a lower fALFF in the left putamen,bilateral cerebellum and bilateral precuneus than controls (all corrected P ＜0.05).ADHD boys showed a lower fALFF in the left cerebellum and a higher fALFF in the bilateral medial superior frontal gyrus than boys without ADHD (all corrected P ＜0.05).ADHD girls showed a higher fALFF in the bilateral cerebellum and in the thalamus than girls without ADHD,and a lower fALFF in the insula than girls without ADHD (all corrected P ＜ 0.05).There was a negative relationship between the fALFF of the left cerebellum of ADHD girls and the scores of inattention symptoms.Conclusion:The fALFF difference exist between ADHD and normal controls,and between boys and girls with ADHD.

OBJECTIVETo present data from a baseline investigation on stroke-related cohort population in rural area of Shanghai.

METHODSA cross-sectional study was carried out in a cluster sampling population aged 40 years and over. General information and data on common risk factors in the population were gathered and cerebral vascular hemodynamic indexes were checked. Hemodynamic score was estimated according to single indexes by unified methods. 5335 persons who had met the inclusion criteria were enlisted in the study. Exposure level of risk factors, prevalence of stroke, and hemodynamic indexes were analyzed and distributional characteristics were described.

RESULTSExposure rate of hypertension, heart disease, diabetes, family history of hypertension, overweight or obesity in males were 31.74%, 6.09%, 1.16%, 3.22%, 17.64%, 29.68% and were 32.76%, 9.22%, 1.55%, 3.84%, 19.22%, 29.44% in female respectively. Standard prevalence of stroke was 1167.3/100000, which in male was significantly higher than that in female (P < 0.05). The change of cerebral vascular hemodynamic indexes was significantly associated with age. Hemodynamic score in 21.3% of the subjects was below 75 points.

CONCLUSIONSAmong population of 40 years old and over in rural areas, hypertension was the principal risk factor regarding the rate of stroke. Prevalence of stroke in males was significantly higher than that in females. Abnormal rate of hemodynamic score was about 20% in this population.

OBJECTIVE To investigate the therapeutic effect and side effect of ibrutinib long-term treatment in systemic lupus erythematosus (SLE) model mice induced by pristane. METHODS Female 6-week old BALB/c mice were ip given pristane 0.5 mL once for SLE induction. Four weeks later, the SLE model mice were divided into three groups based on the body mass and serum level of anti-double-strand DNA (DS-DNA) antibody and treated with 1%methylcellulose (model control group, ig), ibrutinib (30 mg·kg-1, ig) or prednisone (10 mg·kg-1, ig), respectively, once daily for 28 weeks. Every 4 weeks, body mass of each mouse was measured. Autoantibodies against DS-DNA, single-strand DNA (SS-DAN), and histone were tested by ELISA. The incidence of lupus arthritis and clinical score of inflammation and edema were recorded and graded. Biochemical analysis of urea protein, serum urea nitrogen and creatinine was used to evaluate kidney function. Mice were euthanized post 28 weeks of dosing. Inter-leukin-6 (IL-6), interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) were tested by ELISA. The heart, liver, spleen, lung, and kidney were collected and weighed for organ relative mass calculation. Biochemical analysis of serum glutamic-pyruvic transaminase (GPT), glutamic-oxal(o)acetic transaminase (GOT) and alkaline phosphatase (ALP) was used to evaluate liver function. Hind feet were collected for HE staining and pathological scoring to observe renal injury and inflammation. Immunohistochemical staining was used to study IgG immune complexes deposition in kidneys of lupus. RESULTS Compared with normal control group, autoantibodies (anti-DS-DNA, anti-SS-DNA and anti-histone antibodies), renal function indexes (serum creatinine, urea nitrogen and urine protein), and cytokines (IL-6, IFN-γ and TNF-α) levels in model group were significantly increased (P<0.01). The model group mice had obvious clinical symptoms of arthritis (P<0.01), serious inflammation cell invasion (P<0.01), and the mass of kidneys and spleen increased significantly (P<0.01). Compared with model group, after 28 weeks of treatment, ibrutinib decreased the level of anti-DS-DNA, anti-SS-DNA and anti-histone antibodies (P<0.01), decreased the lupus arthritis score (P<0.01) and the morbidity of arthritis, reduced the level of cyto-kines IL-6, IFN-γand TNF-α(P<0.01), reduced the level of serum creatinine, serum urea nitrogen and urine protein (P<0.01), improved pathological symptoms of hind feet such as inflammation, cartilage destruction, bone resorption and pannus (P<0.01), alleviated renal tissue inflammatory cell invasion and the immune-complex precipitation, and reduced the mass of organs (spleen and kidneys, P<0.01) and the level of liver function (GPT and ALP, P<0.01). CONCLUSION Long-term treatment with ibrutinib has therapeutic effect on the model mice of SLE, and has no obvious side effect.

OBJECTIVETo explore the exposed level of stroke risk factors in Fengxian county of Shanghai and the relationships between risk factors and stroke.

METHODSCommunity based populations including 10,565 individuals aged 40 years old and over were cluster sampled from Fengxian county in 2003 or 2004. Status of exposure on common risk factors such as hypertension, cardiovascular disease, diabetes, family history of stroke, cigarette smoking, alcohol intake were gathered while cerebral vascular hemodynamic index (CVHI) was examined, with CVHI score below 75 points as abnormal. During 2003 to 2006, 78 stroke cases occurred. The relationships between risk factors and stroke were analyzed by univariate and Cox proportional hazards regression models.

RESULTSRates of exposure regarding hypertension, cardiovascular disease, diabetes, family history of stroke, obesity (BMI > or = 28 kg/m2), smoking, drinking and CVHI score abnormal were 21.14%, 6.72%, 1.88%, 5.63%, 4.17%, 34.96%, 17.81% and 29.43%, respectively. Data from Univariate analysis indicated that relative risk (95% CI) of above-mentioned risk factors were 2.76 (1.76-4.32), 2.19 (1.16-4.14), 1.52 (0.38-6.19), 1.58 (0.69-3.62), 1.24 (0.45-3.38), 1.75 (1.12-2.73), 2.10 (1.30-3.39) and 12.72 (7.02-23.06), respectively. Results from Cox proportional hazards regression models analysis showed that cigarette smoking, CVHI score abnormal were screened into equation.

CONCLUSIONAmong all the risk factors, rate of hypertension was the highest while hypertension, cardiovascular disease, cigarette smoking, alcohol intake and abnomal CVHI score had remarkable etiological correlations to stroke. Abnormal CVHI score, cigarette smoking seemed to be the independent forecasting factors related to stroke.

OBJECTIVETo investigate the characteristics of RET/PTC and H47PTEN rearrangement and the association between gene rearrangement and clinicopathological properties of thyroid carcinoma.

METHODSRearrangement of RET/PTC-1, RET/PTC-2, RET/PTC-3, ELKS-RET and H4-PTEN (H4/PTEN and PTEN/H4) was analyzed in 139 thyroid tumor tissues by using RT-PCR and sequencing.

RESULTSTwelve RET/PTC-1, 6 RET/PTC-3, 6 H4/PTEN and 7 PTEN/H4 were detected in 126 papillary thyroid carcinomas. In 3 cases, both RET/PTC and H4-PTEN were identified simultaneously. However, repeated experiments did not give the same results of H4-PTEN rearrangement. The overall frequency of rearrangement was 21.4% (27/126). The patients with gene rearrangement were younger (P = 0.02) and had a higher frequency of lymph node involvement (P = 0.02). High frequency of lateral neck lymph node involvement was detected in RET/PTC positive PTC (P < 0.01). PTEN/H4 rearrangement could also be detected in medullary thyroid carcinoma (2/5).

CONCLUSIONSH4-PTEN rearrangement can occur simultaneously with RET/PTC rearrangement in PTC. High predisposition to gene rearrangement is a characteristic of PTC. The patients of PTC with gene rearrangement are younger and have a higher frequency of lymph node involvement.

Objective To describe the distribution of over weight and obesity to discover the level of exposure on risk factors of stroke among people aged 40 and over, in a community-based population.Methods From 2003 to 2004, people aged t≥40 years in a community of Fengxian district in Shanghai were selected by cluster sampling. Out of 11 791 individuals who were selected, 10 565 met the inclusion criteria and responded to the investigation. By face to face interview, a cross-sectional survey was carried out, using a questionnaire for risk factors of stroke. Height, weight and blood pressures were measured and cerebrovascular hemodynamic parameters (CVHP) were checked. Age and gender distribution of over weight and obesity in the population were described. Using 60 year as cut-off point, participants were grouped into three: normal, over weight and obesity by body mass index. Level of stroke risk factor exposure between groups was compared and logistic regression model was used for multiple analyses. Results Proportions of over weight and obesity were 28.5 percent and 4.1 percent in male and 26.3 percent and 4.2 percent in female (P=0.045 ). Systolic and diastolic blood pressure in over weight group were (132.5±19.4)ram Hg and (83.9±10.5)mm Hg(1 mm Hg= 0.133 kPa),which were higher than that in normal weight group and lower than that in obese group (P<0.05). Exposure rate of heart disease,family history of stroke in < 60 year old group and diabetes in ≥60 year group increased along with the increase of weight. Exposure rate of hypertension, abnormality of CVHP score in both age groups were also increased with the increase of weight. Data from multiple logistic regression indicated that hypertension,family history of stroke and heart disease, CVHP score below 75 points, sex and age were independent factors of over weight and obese. Conclusion The prevalence of over weight or obesity in a community-based population among aged 40 years or over was around 30 percent. The overall exposure rate of stroke risk factors were increasing along with the increase of weight, especially for those in the middle age.

OBJECTIVETo investigate the change of early serum TNF-alpha and IL-6 levels in acute cerebral infarction and its significances.

METHODSSerum TNF-alpha and IL-6 levels in 30 health subjects and 35 patients with acute cerebral infarction (ACI) within 6 hours of onset were measured by enzyme linked immunosorbent assay (ELISA); neurological deficits scores (NDS) in all cases were determined, and Spearman test was used for correlation.

RESULTSThe serum levels of TNF-alpha and IL-6 in ACI group were markedly higher than those in health subjects and there was a positive correlation of TNF-alpha and IL-6 levels with 6 h NDS (rs=0.89 and 0.93, P<0.001) and with NDS progression (rs=0.90 and 0.91, P<0.001). Early serum TNF-alpha and IL-6 levels in progressive cerebral infarction (PCI) group were evidently higher than those in stable cerebral infarction (SCI)[(49.56+/-12.12) pg/L compared with (24.30+/-7.4) ng/L and (39.76+/-7.88) ng/L compared with (20.78+/-6.28) ng/L, respectively, P<0.01)].

CONCLUSIONThe early serum levels of TNF-alpha and IL-6 in ACI markedly increase and are closely correlated with disease severity; which may be of value in PCI risk evaluation.
