Objective To analyze the second time blood screening results of ALT deferred donors,and to evaluate the importance of alanine aminotransferase(ALT) testing on the improvement of blood safety.Methods The ALT testing results of 565 360 blood donors from Feb.2006 to Jan.2008 of Shanghai Blood Center were studied retrospectively.The screening results and donation intervals of such donors who delayed their donation just because of their former unqualified ALT level were also analyzed.Results A total of 32 042 donors(5.67%) failed in ALT testing among 565 360 donors.And 3 395 ALT deferred donors participated the second time blood donation,among which 2 205(64.95%) passed the blood screening tests,while the other 1 190(35.05%) failed.Among the 1 190 unqualified blood donors,1 151(33.90%)failed again in ALT testing,and 11(0.32%) in Syphilis,12(0.35%) in HBsAg,7(0.21%) in anti-HCV and 1 in anit-HIV(0.03%).Meanwhile,donors failed both in ALT testing combined with HBsAg,anti-HCV,and anit-HIV sero-converted were 1(0.03%),2(0.06%) and 1(0.03%),respectively.And 72.64% of ALT deferred donors participated the second time blood donation within 6 months.The average donation intervals of donors with qualified ALT level but sero-converted were 140 days(from 24 to 267 days),and those with both unqualified ALT level and sero-converted were 158 days(from 91 to 220 days).Conclusion Before the new methods such as NAT were applied to blood donation screening system,ALT test could prevent the window-period failure of ELISA screening so as to improve the blood safety.

Aim To study the protective effect and mechanism of geniposide on human umbilical vein endothelial cell(HUVEC) injury induced by H2O2.Methods The injured model was established by HUVEC treated with H2O2.HUVECs were cultured in vitro and divided into five groups:control group,H2O2 group and geniposide with different concentrations plus H2O2 group respectively.HUVECs were incubated with 400 ?mol?L-1 H2O2 for 12 hours in the absence or presence of various concentrations of geniposide pre-incubation.Survival rate of HUVECs was determined by tetrazolium assay.The intracellular activities of superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),total nitric oxide synthase(NOS) and extracellular nitric oxide(NO) level were detected.The intracellular reactive oxygen species(ROS) level and the apoptotic index and cell cycle alteration were detected by flow cytometry.Results Geniposide concentration-dependently increased the viability of injured endotheial cells,while increased the activity of SOD,GSH-Px,NOS and NO production.The intracellular ROS level and the apoptotic index were reduced by geniposide.The cell proliferation was increased with geniposide incubation.Conclusion Geniposid may be a potential anti-oxidation agent which has a protective effect against HUVEC injuries induced by H2O2.

AIM: To summarize clinical characteristics and pathogenesis of iridocorneal endothelial syndrome ( ICE ) and investigate the treatment and prognosis.
METHODS:The clinical data of 12 cases (12 eyes) who received treatment in southwest hospital during Jun. 2007 to Feb. 2015 were analyzed retrospectively. The essential progressive atrophy of iris included 7 eyes, Chandler syndrome included 3 eyes, Congan - Reese syndrome included 2 eyes.
RESULTS: A total of 8 eyes were carried out once or multiple filtration surgery; 4 eyes were treated with glaucoma valve implantation. Postoperative follow- up time ranged from 15mo to 5y with the average of 30mo. Three months to 16mo after the surgery, the intraocular pressure of 4 patients were elevated again. Postoperative intraocular pressure was poorly controlled.
CONCLUSION:ICE syndrome is a group of clinically rare and serious eye disease. The excessive proliferation of ICE cells causes the existence of the corneal endothelial cells adhesion to the chamber angle and iris surface, which cause iris atrophy, secondary glaucoma, corneal endothelial decompensation. Currently, glaucoma filtration surgery and glaucoma valve implantation can only control intraocular pressure for several months, but the long-term prognosis is poor.

Objective: To observe the morphological changes of enteric deep muscular plexuses interstitial cells of Cajal (ICC-DMP) in rats with multiple organ dysfunction syndrome (MODS). Methods: Forty Wistar rats were randomly divided into control group and MODS model group. The enteric ICC-DMP network was observed using c-kit immunohistochemical staining with whole-mount preparation technique and confocal laser scanning microscopy , and the ultraslructural features of ICC-DMP was evaluated using transmission electron microscope. Results: Compared with those in control group, the distributions and densities of intestine ICC-DMP in MODS group were significantly decreased (P < 0. 05) , the ICC-DMP network was disrupted and the ultrastructural features of ICC-DMP were severely damaged. Conclusion: The ICC-DMP network was severely damaged in rats with MODS, and the mechanism of gastrointestinal dysmotility in MODS may be related to the morphological changes of ICC-DMP.

This report was to retrospectively analyze clinical data of 29 hyperthyroid patients with concurrent hematocytopenia.Our findings demonstrated that 5 patients developed cytopenia without any antithyroidism drugs(ATDs),while the other 24 cytopenia patients were only found after taking ATD.In the drug intervention group,17 patients received methimazole(MMI)and 7 took propylthiouracil(PTU).Most cytopenia was dose-dependent and occurred within the first 6 months of medication.Twenty subjects received radioiodine therapy,with no impact on blood cells.We suggested that cytopenia might occur at the early stage of ATD therapy and be related with drug and its dose.Blood cell amount should be monitored,especially for initial ATD therapy.As for interaction between PTU and MMI,alternative radioiodine therapy might seem to be relatively safe.

Objective To study the correlation between storage time and the content of 5-hydroxymethylfurfural (5-HMF) in Corni Fructus because of the color change caused by storage time. Methods Corni Fructus samples of different storage time with 0, 1, 2, 3, and 4 years were collected. The contents of 5-HMF were determined by HPLC. Results The HPLC determination method of 5-HMF in Corni Fructus was established. The contents of 5-HMF varied from undetected value to 0.292 8%, with the increase of storage time of 0, 1, 2, 3, and 4 years and the color gradually deepened from red, dark red, reddish brown to brown. The contents of 5-HMF in black wine-prepared Corni Fructus were 0.954 4%-1.837%. Conclusion The browning of Corni Fructus is related to the production of 5-HMF. With the extension of storage time of Corni Fructus, the color gradually deepens and the content of 5-HMF increase significantly. The storage time of Corni Fructus can be suggested to be one year.
