Objective To study the changes of the urinary ?-1 microglobulin and urinary immunoglobulin G(IgG) and to investigate the relationship between these two proteins and the allograft function after renal transplantation.Methods Twenty-nine renal transplant recipients were included in the study.Urinary ?-1 microglobulin and urinary IgG were analyzed at d 1,7,14,21,28 after renal transplantation.The allograft function was evaluated based on the clinical manifestations,laboratory and imaging examinations,and the relationship between urinary ?-1 microglobulin,IgG and serum cretinine(SCr) were analysed. Results Urinary ?-1 microglobulin and urinary IgG correlated with SCr after renal transplantation in one month.Of all the 29 cases,14 experienced allograft function recovery(group A),and 15 failed(group B).Urinary ?-1 microglobulin decreased significantly in group A(P

With the development of organ transplantation for nearly half a century, currently the hot issues in clinical renal transplantation have already shifted to the application of low toxicity immunosuppressive drugs and their projects, as well as the research of technique which induces low or no immunity response to the specific donor. At present the main effective strategies of inducing immune tolerance are donor specific blood transfusion and donor specific bone marrow transplantation. This article summarizes the background, mechanism and clinical application of these two strategies.

The major goal of microbial ecology is to study the structure and function of complex micro-bial communities. New molecular biological techniques have been successfully applied to analyze mi-crobial community structure. However they do not provide information on the physiologic properties of the detected microorganisms. A new tool for structure-function analyses in microbial ecology, micro-autoradiography combined with fluorescence in situ hybridization (MAR-FISH) can be used to simul-taneously examine the phylogenetic identity and the specific activity of microorganisms within a com-plex microbial community at a single-cell level. This article reviews the principle, experimental steps of MAR-FISH technique. The application of this technique in study of the environmental microbial com-munity and function is also summarized.

Objective T o evaluate the application value for the prognosis of m echanical ocular injury cases using ocular traum a score (O TS). Methods Four hundred and eleven cases of m echanical ocular traum a w ere retrospectively review ed. O f the 449 eyes, there w ere 317 closed globe injury and 132 open globe injury. O T S variables included num erical values as initial visual acuity, rupture, endophthalm itis, perforat-ing or penetrating injury, retinal detachm ent and relative afferent pupillary block. T he differences be-tw een the distribution of the final visual acuity and the probability of standard final visual acuity w ere com pared to analyze the correlation betw een O T S category and final visual acuity. T he different types of ocular traum a w ere com pared. Results C om pared w ith the distribution of final visual acuity in standard O T S score, the ratio in O T S-3 category w as statistically different in present study, and no differences w ere found in other categories. Final visual acuity show ed a great linear correlation w ith O T S category (r=0.71) and total score (r=0.73). C om pared w ith closed globe injury, open globe injury w as generally associated w ith low er total score and poorer prognosis. R upture injury had poorer prognosis com pared w ith penetrating injury. Conclusion T he use of O T S for the patients w ith ocular traum a can provide re-liable inform ation for the evaluation of prognosis in forensic m edicine.

Objective To evaluate dexmedetomidine-induced cardioprotection in a mouse model of lung ischemia-reperfusion (I/R) and the relationship with endoplasmic reticulum stress.Methods Forty healthy SPF male C57BL/6J mice,weighing 20-24 g,aged 8-10 weeks,were divided into 4 groups (n=10 each) using a random number table:sham operation group (Sham group),lung I/R group (I/R group),dexmedetomidine group (Dex group) and dexmedetomidine plus atipamezole (specific α2-adrenergic receptor antagonist) group (DA group).The model of lung I/R injury was established by clamping the left hilum of lung for 30 min followed by 180 min of reperfusion.In group Sham,only sternotomy was performed,the hilum of lung was not clamped,and the mice were mechanically ventilated for 210 min.In Dex and DA groups,dexmedetomidine 20 μg/kg and dexmedetomidine 20 μg/kg plus atipamezole 250 μg/kg were injected intraperitoneally,respectively,at 30 min before establishment of the model.At 180 min of reperfusion,blood samples were collected from the orbit for determination of creatine kinase-MB (CK-MB) and lactic dehydrogenase (LDH) activities in serum.The animals were then sacrificed,and hearts were removed for determination of apoptosis in cardiomyocytes (by TUNEL) and expression of phosphorylated c-Jun N-terminal kinase (p-JNK),caspase-12,CCAAT/enhancer-binding protein homologous protein (CHOP) and glucose-regulated protein 78 (GRP78) in myocardial tissues (by Western blot),and expression of JNK,caspase-12,CHOP,GRP78 mRNA in myocardial tissues (by real-time polymerase chain reaction).Apoptosis index was calculated.Results Compared with Sham group,the serum CKMB and LDH activities and apoptosis index were significantly increased,the expression of p-JNK,JNK mRNA,and caspase-12,CHOP and GRP78 protein and mRNA was up-regulated in I/R,Dex and DA groups (P<0.01).Compared with I/R group,the serum CK-MB and LDH activities and apoptosis index were significantly decreased,the expression of p-JNK,JNK mRNA,and caspase-12 and CHOP protein and mRNA was down-regulated,the expression of GRP78 protein and mRNA was up-regulated in group Dex,and the expression of GRP78 protein and mRNA was significantly up-regulated (P<0.01),and no significant change was found in the other parameters in group DA (P>0.05).Compared with DEX group,the serum CK-MB and LDH activities and apoptosis index were significantly increased,the expression of pJNK,JNK mRNA,and caspase-12 and CHOP protein and mRNA was up-regulated (P<0.01),and no significant change was found in the expression of GRP78 protein and mRNA in DA group (P>0.05).Conclusion Dexmedetomidine can reduce myocardial injury induced by lung I/R,and the mechanism may be related to activation of α2-adrenergic receptors and inhibition of endoplasmic reticulum stress in myocardial cells of mice.
