With the development of the quality of life, the morbidity of hyperuricemia is increasing year by year. At the same time, it appears that this disease attacks the young people currently. As the study of pathogenesis of hyperuricemia advanced, a series of uric acid transporters were found during this process. Meanwhile, the definition of transporterome was proposed. They were divided into three groups according to the functions: reabsorption proteins, excretion proteins and skeleton proteins. At moment, the drugs for hyperuricmia mainly include uric acid composition inhibitors and uric acid excretion promoters. Since the excretion of uric acid plays a leading role during the process of attack of hyperurecimia, it makes sense to explore Chinese medicines with clear mechanism targeting the transporterome. Therefore, this paper would focus on transporterome and summarize the mechanisms of Chinese medicines in treating hyperuricemia.

OBJECTIV: e To find the correlation between real best corrected visual acuity (BCVA) and testing results of microperimetry and visual evoked potential (VEP) and to explore a new method in recording BCVA in macular disease. METHODS: Sixty-two patients with macular disease (macular disease group, 62 eyes) and eighteen healthy volunteers (control group, 36 eyes) had BCVA, microperimetry and VEP recorded. RESULTS: (1) By microperimetry, the values of retinal mean sensitivity and fixation percentage in macular disease group were lower than that in control group. The bicurve ellipse area in macular disease group was higher than that in control group. By VEP, P100 amplitude under 0.5 cpd and 2 cpd in macular disease group were significantly higher than that in control group and the latency was prolonged (P < 0.05). (2) In macular disease group, BCVA had significant positive correlation with retinal mean sensitivity, bicurve ellipse area, macular central 2 degrees and 4 degrees fixation percentage, respectively (P < 0.05). There was a significant correlation between retinal mean sensitivity and P100 amplitude (P < 0.05). (3) Multiple linear regression equation was y = 0.053 x1+0.008 x3+3.897 (y was BCVA, while x1 was retinal mean sensitivity and x3 was P100 amplitude under 2 cpd). CONCLUSION Combined use of microperimetry and VEP is useful in the assessment of BCVA in macular disease.

Objective To establish the murine congenital infection model by MCMV and observe the pathological changes and infection status of brain tissue.Methods After anesthesia,mice who were pregnant 11-13.5 days (E11-13.5 d) were intra-amniotic injected one uterus by one with virus (MCMV K181 suspension,1 μl,1×103 PFU).The control group of the same period was intra-anmiotic injected with culture medium DMEM (1 μl).Carefully reset the uteruses and close the abdomen.After 5 days of separated feeding,kill the pregnant mice,take the fetus out of the uterus,anesthetize and kill them.Make frozen sections of these fetal brains.Some sections were stained using conventional HE method,to observe the pathological changes under the light microscope.Detect MCMV early antigen in the brain tissue by immunohistochemistry staining and immunofluorescence assay.Results The survival rates of the infected group were 71.9％.Compared with the control group,intra-amniotic inoculation of MCMV does not affect the rate of fetal survival,fetal absorption,fetal death and the average weight of the heads,but decrease their average weight of the bodies.The pathological changes are found in the brain tissue of the mouse in the infection group.Through enzyme immunohistochemistry assay,there are many MCMV infected cells in brain-ventricular zone,brain subependymal zone,cerebral cortex and hippocampus area in the infection group.Similar findings were observed by immunofluorescence method.Conclusion By intra-amniotic injection of MCMV suspension,murine model of MCMV congenital infection can be successfully established.This model could be used to study the mechanisms of encephalodysplasia caused by congenital CMV infection in vivo.

Objective To investigate the effects of cognitive therapy combined with picture recognition training on depression after stroke (PSD).Methods Sixty patients with PSD after cerebral infarction were randomized into study and control groups.All accepted routine rehabilitation therapy.In addition,the study group accepted cognitive therapy combined with picture recognition training.The effects were assessed in terms of average reaction time and accuracy in picture recognition,and using the Hamilton depression rating scales (HAMDs) and the Barthel index (BI) before and after 4 weeks of treatment.Results The average reaction time and accuracy in picture recognition and the HAMD and BI scores improved significantly in both groups.The effects in the study group were significantly better than those of the control group.Conclusion Cognitive therapy combined with picture recognition training can alleviate depression symptoms and improve ability in the activities of daily living after stroke.

Objective To investigate whether cesarean section on pregnant women with chronic hepatitis B virus (HBV) infection may reduce mother-to-infant transmission risk of HBV.Methods Preserved serum samples of pregnant women at 15-20 weeks of gestation which were collected from July 2002 to August 2004 in 14 counties of Jiangsu Province were analyzed retrospectively.These samples were tested for HBV serologic markers with enzyme immunoassay,and 419 cases of positive hepatitis B surface antigen (HBsAg) were found.HBV DNA level of these HBsAg-positive women were further quantitatively measured with real-time polymerase chain reaction assay.Children of these 419 HBsAg-positive mothers were followed up during October 2009 to March 2010 and 298 of them were contactable (71.1％),among which 281 were enrolled in final analysis as they had complete information and had been vaccinated with three regular doses of HBV vaccine during infantile period.The 281 children were tested for serum HBV markers.The HBV infection rate in these children at age 5-7 was compared between those born by cesarean setion (CS group,n =136) and by vaginal delivery (VD group,n=145).T-test,x2 test or Fisher's exact test was used to analyze relevant parameters.Results(1) Maternal HBeAg-positive rates [25.7％ (35/136) vs 34.5％ (50/145)],HBV DNA levels in HBeAg-positive women [(2.30 × 106) IU/ml vs (2.09× 106) IU/ml],the percentages of HBIG injection after birth [38.2％ (52/136) vs 35.9％ (52/145)],breastfeeding ratios [82.4％ (112/136) vs 75.9％ (110/145)],and children' s ages at the follow-up [(5.9 ± 0.8) vs (6.0±0.6)] were comparable between CS group and VD group (all P＞0.05).(2) Among these 281 children,272 (96.8％) were HBsAg-negative,9 (3.2％) were HBsAg-positive and 163 (58.0％) were anti-HBs-positive.The prevalence of HBsAg-positive [(2.9％ (4/136) vs 3.4％ (5/145)],HBsAg negative and anti HBc positive [0.0％ (0/136) vs 1.4％ (2/145)] and anti-HBs positive [57.4％(78/136) vs 58.6％(85/145)] in CS group were similar to those in VD group.Conclusions Cesarean section does not reduce the risk of mother-to-infant transmission of HBV.In clinical practice,elective cesarean section should not be suggested in order to prevent HBV vertical infection.

Objective To retrospectively analyze the importance of preoperative ultrasound and D-dimer determination for patients with traumatic fractures so as to evaluate the value of vascular color Doppler ultrasound in diagnosing of vein thrombosis and the correlation between D-dimer level and lower extremity vein thrombosis. Methods The study involved 1000 in-patients with multiple traumatic fractures, femoral fractures, tibial fractures or tibiofibular fractures admitted from March 2008 to April 2009 who were prepared for open reduction surgery. There were 568 males and 432 females, at age range of 20-90 years ( average 54.8 years). Vein D-dimer was examined in the morning on the second day after admission. Vascular color Doppler ultrasound was performed on the lower extremity one day before operation (after the swelling faded away, about 4-10 days after fracture). Results The vascular color Doppler ultrasound on the lower extremity showed vein thrombosis of the lower extremity in 64 patients (6.4%) including 26 patients with iliac- femoral vein thrombosis, 10 with popliteal-tibial vein thrombosis and 28 with gastrocnemius or soleus muscle vein thrombosis. On the second day after operation, out of 736 patients (73.6%) with D-dimer above normal (324 μg/L), 56 patients (7.6%) developed thrombosis afterwards;of 264 patients (26.4%) with normal D-dimer, eight patients (3.03%) developed thrombsis. Incidence of thrombosis in patients with D-dimer above 650 μg/L was higher than that in patients with D-dimer below 650 μg/L (P＜0. 01). Conclusions Preoperative lower extremity vein Doppler ultrasound in traumatic fracture patients can lower the risk of fatal lung thrombosis caused by existing deep vein thrombosis.D-dimer above normal level indicates tendency of thorombosis. However, normal D-dimer still have the possibility to develop thrombosis, which deserves attention.
