Post-translational modification by ubiquitin and ubiquitin-like modifiers(Ubls) is one of the most important mechanisms regulating a wide range of cellular processes in eukaryotes.Previous research showed that,through covalently modification by ubiquitin or ubls,the substrate proteins can be regulated in many different ways like stability,subcellular localization,enzymatic activity,protein-protein interaction and so on.Therefore,we believe,that ubiquitin and ubls play very important roles in cellular and biological processes by modifying plenty of proteins.To better understand the ubiquitin and ubls system,proteomic approaches have been developed to purify and identify more protein substrates.Large-scale idendification of ubiquitin/ubls-modification sites by mass spectrometry is particularly important for understanding the molecular mechanism and function of ubiquitin/ubls modification.Upto the present,more and more scientists are getting interested and participating in proteomics research of ubiquitin/Ubl modifications.This review summarizes the rencent results in this field.

ObjectiveTo explore the effects of hemofiltration on serum enzyme (SE),endotoxin (ET) and malonaldehyde (MDA) of dogs with heat stroke caused shock.MethodsSixteen healthy male hybrid dogs were randomly divided into 2 groups,8 for each:as heat stroke group (HS group ) and hemofiltration group (HF group).Severe heat stroke model was induced with high temperature.The dogs were taken out of the heating cabin when it reached heat stroke level,and then observed under normal temperature without treatment.The dogs in HF group was immediately treated with hemofiltration.The changes of SE,ET,MDA of two groups of dogs were observed and the survival time between two groups was compared,ResultsThe time from heat exposure to shock was ( 107.00 ± 28.52 ) and ( 111.38 ± 22.24 )minutes in HS group and HF group respectively ( t =- 0.354,P =0.729 ).The SE ( CK,LDH,ALT,AST) of the dogs were all higher after heat stroke,and the dogs of two groups showed no siginificant difference (P > 0.05).At three hours after heat stroke,the SE increased apparently in HS group and HF group,but the level was significantly lower in HF group. Before heat stroke,the serum ET showed no siginificant difference between two groups ( P > 0.05 ).After heat stroke,the serm ET was much higher than before ( P <0.01 ),but there was still no siginificant difference between two groups ( P >0.05 ).At three hours after heat stroke,the ET increased both in HF group and HS group,but the level was lower in HF group.Before heat stroke,the serm MDA had no siginificant difference between two groups ( P > 0.05 ).After heat stroke,the serm MDA was much higher than before ( P < 0.0l ),but there was still no siginificant difference between two groups (P > 0.05 ).After heat stroke in three hours,the MDA of HS group rose apparently while HF group slowly declined.The median survival time of HF group was 180 min while HS group was 75 min,the survival rate showed siginificant difference (P < 0.01 ).Conc4usions HF can improve the prognosis of dogs with heat stroke caused shock,prolong its survival time,reduce mortality.The mechanism is probably that HF clear serum MDA,partially clear serum ET and then eventually reduce cell and tissue injury and reduce SE.

Objective With the isocentric C-arm (Iso-C) three-dimensional computerized navigation system,cadaveric pelvic specimens were used to imitate double screw fixation of the symphysis pubic.Practicability and safety of the screw trajectory were examined postoperatively by local cadaveric dissections and imaging tests.Methods Pelvic specimens were harvested from 8 male and 7 female adult cadavers.Double screw placement in symphysis pubic was performed using the Iso-C three-dimensional navigation and entry point and safety trajectory was achieved.With the detailed local dissection postoperatively,distances from screw entry and exit points to unilateral structures (spermatic cord,femoral artery and vein,femoral nerve,obturator artery and vein,obtrurator nerve,and so on) were measured respectively.After complete removal of surrounding soft tissues of the specimen with only bony structure kept,the entry angle and length were calculated.Accuracy of double screw fixation of symphysis pubic was further checked using X-ray and CT.Results Entry point of the first screw was at the junction of unilateral pubic tubercle and transitional site of superior pubic ramus.Mean angle of the first screw with the horizontal plane was (7.7 ± 1.9) ° in men and (8.1 ± 1.7) ° in women.Mean angle between the first screw and coronal plane was (7.8 ± 1.8)° in men and (7.7 ±2.0)° in women.Entry point of the second screw was in the same place in the contralateral pubic tubercle.Mean angle between the second screw and horizontal plane was (30.6 ± 4.0) ° in men and (30.8 ± 3.4) ° in women.Mean angle between the second screw and coronal plane was (9.1 ± 3.0)°in men and (9.2 ± 3.3)°in women.Conclusions With the three-dimensional computerized navigation system,the bony channels of double screws implanted in the symphysis pubic are achieved and reliable.Percutaneous double screw fixation is feasible to treat the pubic symphysis diastasis.
