1.Advance in treatment of hyperuricemia by Chinese medicine based on uric acid transporterome.
China Journal of Chinese Materia Medica 2015;40(22):4346-4350
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.

Objective To explore the determination of dioxin in wastewater samples pretreated by solid phase microextraction(SPME). Methods The wasterwater samples were purified and enriched by SPME, then were determined with HRGC-HRMS for the concentration of dioxin in wastewater samples. Results The most suitable conditions of the pretreatment were 30 min microextraction at 45 ℃. The detection limit was 0.05 pg/?l. RSD was lower than 10%. The recovery rates were 99%-102%. The concentration of total dioxins in wastewater sample was 0.78 pg/?l. Conclusion The method of the determination of dioxins in wastewater by SPME was simple and quick, and presented a broad prospects for application.

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 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.

αB-crystallin is the structural protein of vertebrate lens, w hich is w idely expressed in non-lens tissue. As one of the heat shock protein fam ily m em bers,αB-crystallin possesses biological proper-ties of m olecular chaperones and anti-apoptotic effects. Multi-factor injuries, such as retinopathy, inflam-m ation and nervous system diseases, have a closely relationship w ith αB-crystallin. T his paper review s the research progress of the expression and m echanism ofαB-crystallin in retina and extraocular tissues and organs.

Objective To investigate concentration and distribution in blood and tissues of form icacid after m ethanol intoxication in rats. Methods The Sprague-Dawley rats were divided into groups for con-trol group and 3-day and 7-day intoxication treatm ent groups. The experim ental groups were adm inis-tered m ethanol by gavage with the initial dose of 8 m L/kg and followed with 4 m L/kg supplem ental dose 24 h later. After 3 days and 7 days later, rats were killed by decapitation. Then sam ples of cardiac blood, liver, kidney, brain, heart and stom ach of each group were collected. Form icacid concentrations were detected by high perform ance liquid chrom atography. Results Form icacid concentrations in tissues were higher than in blood. Com pared with 3-day intoxication group, there was an increase form icacid of concentration in brain and stom ach in 7-day intoxication group, while a decrease in liver and kidney (P<0.05). Conclusion H igh perform ance liquid chrom atography could be used to accurately detect form icacid. As the m etabolite of m ethanol, form icacid accum ulates in rat blood and tissues after intoxication and the concentrations in organs and tissues are obviously higher than in blood.
