Objective:To evaluate the efficacy and safety of micronised fenofibrate on lipid and uric acid metabolism in patients with hyperlipidemia.Methods: A total of 116 patients with hypertriglyceridemia and hyperuricemia received 200 mg micronised fenofibrate for 4 weeks.Physical and laboratory investigations of lipid profiles,serum uric acid,and 24 h urine uric acid,for adverse effects were assessed.Results:(1) Serum triglyceride(TG) was significantly reduced by 51%,whilst high density lipoprotein cholesterol(HDL-C) increased 24% after 4-week fenofibrate treatment.Moreover,serum total cholesterol(TC) and low density lipoprotein cholesterol(LDL-C) were reduced by 10% and 12%,respectively.(2) Serum uric acid levels were significantly reduced by 28.3% [from(462.8?73.5) ?mol/L to(320.1?83.0) ?mol/L] after fenofibrate treatment,independent of baseline uric acid le-vels.There was no difference in serum uric acid changes between male gender and female gender(29.8% and 25.1%,respectively).(3) Urine uric acid levels were increased by 36.0% [from(2 874.2?503.4) ?mol/L to(3 604.2?769.7) ?mol/L].The urine uric acid changes were 41.1% in male gender group and 33.4% in female gender group.The uric acid clearance/creatinin clearance ratio was increased in all cases after treatment.Conclusion: Micronised fenofibrate treatment could significantly improve lipid and uric acid metabolism in patients with hypertriglyceridemia and hyperuricemia,and is ge-nerally safe and well tolerated.The anti-hyperuricemic effect of fenofibrate is a result of increasing the urinary excertion of uric acid,independent of baseline level and gender.

Objective To explore the effect of self-control deficit on ego depletion in patients with type 2 diabetes mellitus (T2DM) on the basis of ego-depletion theory.Methods Dual-Task Paradigms were used to manipulate self-control depletion.This study employed 2×2 between-study design.T2DM patients were chosen as the study group,and healthy volunteers were selected as normal control group,with 30 cases in each group.They were randomly assigned to depleted group (30 cases) or non-depleted group (30 cases).Depleted group completed classical Stroop task,whereas,non-depleted group completed conformant Stroop task.Finally,the ego-depletion effects were investigated by Simon Task.Results The number of reaction errors in the T2DM group was significantly greater than that in the normal group under the compatible condition ((8.73±6.09) vs (5.10±4.35),F(1,58)=7.125,P=0.010),and the incompatible condition((10.60±10.10)vs (3.97±3.97),F(1,58) =10.890,P=0.002).The reaction time in the T2DM group was longer than that in the normal group under the compatible condition ((673.33 ± 83.54) ms vs (663.18± 123.27) ms,F(1,58) =0.139,P=0.711) and the incompatible condition ((691.83± 107.75) ms vs (644.07± 106.69) ms,F(1,58) =2.964,P=0.091),however,the differences were not statistically significant.The number of reaction errors in the depleted group was more than that in the non-depleted group under the compatible condition (F(1,58) =0.821,P=0.369),and the incompatible condition (F(1,58) =0.231,P=0.632),but the difference was not statistically significant.The reaction time in the depleted group was longer than that in the non-depleted group under the compatible condition(F(1,58) =1.623,P=0.208),and the incompatible condition (F(1,58) =0.806,P =0.373),the differences were not statistically significant.The interactions between participants type and experimental conditions were not significant.Conclusion The patients with T2DM are in a state of chronic depletion and self-control will potentially aggravate ego depletion,which leads to decline in self-control ability and difficulties in self-management.

Objective To study the prevalence of retinopathy of prematurity (ROP) in preterm infants in Xiamen, Fujian. Design Retrospective case series. Participants From Oct. 2004 to Dec. 2008, 375 infants with birth weights ≤2500g or gestational age ≤32w were screened in Xiamen the First Hospital. Methods Initial examinations with the binocular indirect ophthalmoscopy and the scleral depression began at 4～6 weeks after birth or at 32 weeks postconception. All infants were followed-up until a stable retinal situation was reached. Main Outcome Measures The prevalence of ROP. Results Retinopathy of prematurity was detected in 10.93% of 375 neonates, including 18 eyes of stage 1, 48 eyes in stage 2, 14 eyes in stage 3, 2 eyes in AP-ROP. The prevalence of ROP in the infants with the birth weight ≤1000g, 1001-1500g and 1501-2000g was 45%, 17.07%, 7.01%, respectively; the occurrence rate of ROP in the infants with the gestational age ≤28 weeks, 29-30 weeks, 31-32 weeks, 33-34 weeks was 34.48%, 2.07%, 12.71%, 8.25%, respectively. Conclusions Earlier screening for ROP is very important. Low birth weight and young gestational age are the most important risk factors in the development of ROP.

Objective To investigate the role and the mechanism of ppk1 gene (coding for polyphosphate kinase 1) in oxidative stress resistance in uropathogenic Escherichia coli (UPEC).MethodsMutant strains with ppk1-deletion (△pk1) and complemented strains (△pk1-C) were constructed based on the UPEC strain CFT073.A comparative analysis was conducted to analyze survival rates of CFT073, △pk1 and △pk1-C strains at different time points while they were under oxidative stress.Differences in protein expression between CFT073 and △pk1 strains were analyzed using mass spectrometric analysis.Differences between CFT073 and △pk1 strains in expression of katG and katE genes were analyzed using real-time quantitative RT-PCR.Results The survival rate of △pk1 strains was lower than that of CFT073 strains at every time point, while the survival rate of △pk1-C strains was basically the same as that of CFT073 strains.Gel image analysis and mass spectrometric analysis revealed that six proteins were down-regulated and one was up-regulated in △pk1 strains as compared with those in CFT073 strains.Expression of the catalase-coding genes katG and katE in △pk1 strains were respectively (20.5±8.2)% and (20.9±6.9)% of those in CFT073 strains (P<0.05).Conclusion The ppk1 gene plays an important role in oxidative stress resistance in UPEC by modulating the expression of catalase-coding genes katG and katE.

Objective To investigate the effect of state anxiety and trait anxiety on attentional orienting of heroin addicts. Methods State anxiety and trait anxiety was measured by State-Trait Anxiety Inventory (STAI). Forty heroin ad?dicts (36 males and 4 females) and 40 healthy controls (36 males and 4 females) participated in cue-target task. Atten?tional orienting and reorienting were measured in valid cue trials and invalid cue trails. Results Heroin addicts had sig?nificantly greater state anxiety [(42.65 ± 6.58) vs. (36.60 ± 8.91)] and trait anxiety [(44.43 ± 7.67) vs. (37.00 ± 8.63)] values than controls (P<0.05). The state anxiety was significantly correlated with orientation RT difference (r=-0.259, P=0.020) and disengaging/reorientation RT difference (r=0.333, P=0.003) in heroin addicts. Trait anxiety was also significantly cor?related with orientation RT difference (r=-0.248, P=0.026) and disengaging/reorientation RT difference (r=0.356, P=0.001) in heroin addicts. Conclusion Heroin addicts have significantly greater anxiety than healthy controls. Both their state anxiety and trait anxiety are associated with attentional orienting and disengaging/reorienting.

Background Stem cell transplantation represents a promising treatment option for patients suffering from degenerative disorders.Accumulating evidences indicate that mesenchymal stem cells (MSCs) are able to differentiate into retinal pigment epithelial (RPE)-like cells.However,MSCs are difficult to obtain.Human adipose mesenchymal stem cells (ADSCs) are proved to have similar properties to MSCs,but relevant study is less.Objective This study was to assess the feasibility of human ADSCs differentiating into RPE-like cells and the safety of its application in vivo.Methods The third generation of human ADSCs were incubated into 6-well plate,and 100 ng/ml epithelial growth factor,50 μ mol/L taurine and 5×10-7 mol/L retinoic acid were added into the medium 12 hours after cultured to induce the cells,and conventional cultured cells were used as the control group.Induced cells were traced with PKH26,and Pan-cytoke ratin (Pan-CK) monoclonal antibody was used to identify the cells under the fluorescence microscope.Induced RPE-like cell suspension of 1 μl was intravetreally injected in the right eyes of 6 BALB/c mice,and equal volume of PBS was used in the same way in another 6 mice.The animals were sacrificed 1 month after injection,and the retinal morphology was examined by histopathology under the optical microscope.The ultrastructure of retinal ganglion cells (RGCs) was examined by the transmission electron microscope.The use and care of the animals complied with Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results Cultured human ADSCs grew well with the slender polygone shape.Cell membranes showed the red fluorescence for PKH26 after induced.In addition,Pan-CK was expressed in the cell membranes with the red fluorescence in the induced cells,but the response was absent in the control cells.One month after intravitreal injection,induced cells located on the retinal surface,and the retinal morphology was clear under the optical microscope.No abnormality in RGCs was seen under the transmission electron microscope.Conclusions Human ADSCs can differentiate into RPE-like cells after induction.PKH26 can mark induced cells well.There is no adverse effect of induced cells on retina after intravitreal injection in a short-term duration in mice.

Objective To investigate the factors influencing basic rehabilitation service needs of people with disability at Zhabei District in Shanghai .Methods Primary rehabilitation demands and services of 10 311 disabled persons in Zhabei District were surveyed.Results The screening rate of persons with disability having primary rehabilitation demands was 83.5%. And the gender, age, type of disability, disability level, education, employment might be the factors affecting the primary rehabilitation demands of people with disability.Conclusion The primary rehabilitation service demands vary in deferent types of people with disability. The various services based on the extensive rehabilitation services should be provided to deferent categories of people with disability.

Objective To understand the status of special rehabilitation service demands of people with disability at Zhabei District in Shanghai and to provide the basis for the policy development.Methods Screen rate (SR) was used to indicate the level of demand of rehabilitation service, the data were analyzed with SPSS 13.0 statistical software.Results There were 4 349 persons with disability who demanded the special rehabilitation service; the SR of “on-site rehabilitation service” demands was the highest among the whole persons with disability; the SR of “personalized allotment of supplies and appliances” demands of the intellectual disability and mental disability was lower than the other types; the SR of special rehabilitation service demands of the female, the elderly, the low cultural level, the unemployed and the people with severe disability were relatively higher.Conclusion The form of “on-site rehabilitation services” needs to improve based on the demand of the disabilities; “personalized supplies and appliances” for the intellectual disability and mental disability needs to further develop; the rehabilitation services targeted to the female, the elderly, the low cultural level, the unemployed and the people with severe disability need to improve.

Objective To provide the advice on how to optimize the allocation of resources and make other policy through the analysis factors affecting rehabilitation services needs of people with disability at Zhabei district in Shanghai.Methods The factors affecting rehabilitation services needs such as types of disability, disability levels, education, employment, marital status, age and sex were analyzed with Logistic analysis.Results The factors affecting primary rehabilitation services were types of disability, education, employment situation, marital status and sex. And people with disability had the characters of female, hearing disability, retired returned to more primary rehabilitation services, with OR values being 1.219, 1.544 and 1.533 respectively compared with itself controls. And the high educational disable people' will, returning to primary rehabilitation services, was weaker compared with low educational disable people. The factors affecting special rehabilitation services were types of disability and employment situation. And people with disability had the characters of hearing disability, unemployment returned to more special rehabilitation services, with OR values being 2.380 and 1.310 respectively compared with itself controls.Conclusion The rehabilitation needs are different among different groups people with disability, so the factors affecting rehabilitation services needs such as types of disability, education, employment situation, marital status and sex should be taken into consideration while activating primary rehabilitation services, while the types of disability and employment situation should be taken into more consideration while activating special rehabilitation services.

Objective To observe the effect of Kechuanning Oral liquid on the expression of P13K in CD4+and CD8+T cells of asthma rats induced by respiratory syncytial virus (RSV), and explore its mechanism of preventing and treating asthma induced by virus. Methods SD rats were randomly divided into phosphate-buffered saline (PBS) control group, model group, dexamethasone and salbutamol group (positive drug group), and Kechuanning oral liquid group. Ovalbumin asthma rats model was built and induced by RSV. CD4+and CD8+T cells were separated by magnetic beads method. The expressive level of PI3K-110αin T cells was detected by immumofluorescence method with flow cytometry. Results Compared with PBS control group, positive drug group and Kechuanning oral liquid group, the CD4+and CD8+T cells percentage and the expression level of PI3K-110α in CD4+ and CD8+T cells of model group were significantly higher. The differences were statistically significant (P<0.01). The CD4+and CD8+T cells percentage was not associated with the expression level of PI3K-110α in CD4+ and CD8+T cells of each group by Pearson correlation analysis. Conclusion The CD4+ and CD8+T cells involve in the asthma immunity balanced modulation, and the level of PI3K expressed by CD4+ and CD8+T cells increase distinctly. Kechuanning oral liquid can restrain the expression of PI3K in CD4+ and CD8+T cells, which might be one of the immunologic mechanisms of treating asthma.
