Objective To study the effect of batroxobin combined with Yinxingdamo injection on serum endothelin(ET),nitric oxide(NO),superoxide dismutase(SOD),vascular cell adhesion molecule-1(VEGF-1)in patients with sudden deafness(SVCAM-1),to explore the best treatment for patients with sudden deafness.Methods Ninety patients with sudden deafness from June 2014 to June 2015 were recruited as the subjects of this study.The patients in control group were treated with batroxobin and batroxobin and ginkgo dipyridol.The levels of serum ET,NO,SOD,sVCAM-1,time of symptom recovery and the curative effect were observed.Results After treatment,the levels of ET,NO and sVCAM-1 in the observation group were significantly lower than those in the control group [(64.28±5.72)pg/mL vs(67.36±6.31)pg/mL,(43.08±9.53)μmol/(93.24±11.25)NU/mL](P<0.05).The results showed that there was no significant difference between the two groups.The recovery time of tinnitus,auria and vertigo in the observation group were less than those in the control group [(3.86±1.02)d vs(5.97±1.34),(5.03±1.24)d vs(7.37±2.01)d,(8.09±2.10)d vs 9.07±2.37)d](P<0.05).The total effective rate in the observation group was better than that in the control group(93.33％vs 75.55％,P<0.05).Conclusion Batroxobin combined with ginkgo dipyridolum injection can decrease the level of ET,NO and sVCAM-1,improve the level of SOD,and improve the microcirculation of the inner ear.Compared with the single effect of Batroxobin More desirable,worthy of promotion.

With anti-myc and ras oncogene product monoclonal antibodies p62 and p21, 27 cases of squamous epithelial tumors of the skin (SETS) specimens were examined. The results showed that 62.9%(17/27) and 66.7%(18/27) of the specimens expressed p62 and p21 proteins respectively. Thirteen specimens expressed p62 and p21 proteins simultaneously. The results also showed that p62 was mainly seen in the poorly differentiated squamous cell carcinoma specimens, while p21 was mainly in the relatively well-differentiated specimens. The authors consider that myc and ras oncogenes might have different effects on the develpment of the SETS, and their synergy might be associated with the persistant growth of SETS.

Objective To investigate the effects of NB-UVB on the expression of Gadd45α as well as cell apoptosis and cycle of human HaCaT keratinocytes.Methods Cultured HaCaT cells were exposed to various doses (100,200,400 mJ/cm2)of NB-UVB followed by an additional culture of 6,12 and 24 hours,respectively.Reverse transcription PCR and Western blot were performed to detect the mRNA and protein expression of Gadd45α respectively in HaCaT cells,cell counting kit 8 (CCK8)to measure the proliferation of cells,and flow cytometry to determine the cell cycle distribution of HaCaT cells before and after the exposure to NB-UVB.Results Gadd45α was expressed in HaCaT cells.After exposure to NB-UVB of the three doses,the mRNA and protein levels of Gadd45α increased at 6 hours and 12 hours,but declined at 24 hours,and significant changes were observed in HaCaT cells at the three time points after exposure to NB-UVB of the three doses (all P<0.05).The Gadd45α/β-actin mRNA ratio was 1.4360±0.6551.1.8633±0.0979,1.9266±0.1724 in HaCaT cells 12 hours after irradiation to NB-UVB of 100,200 and 400 mJ/cm2,respectively,significantly higher than that in unirradiated cells(0.6000±0.1276,all P<0.05).Also,increased Gadd45α/β-actin protein ratio was noted in HaCaT cells 12 hours after irradiation to NB-UVB of 100,200 and 400 mJ/cm2 compared with unirradiated cells (0.0773±0.0005,0.1936±0.0015,0.2373±0.0015 vs.0.0290±0.0010,all P<0.05).NB-UVB inhibited the proliferation of HaCaT cells in a time-and dose-dependent manner.Flow cytometry showed that irradiated HaCaT cells were blocked in G2 phase of the cell cycle.and the percentage of HaCaT cells in G2 phase was 13.53%±1.03%,17.77%±2.25%,30.03%±4.29%afler exposure to NB-UVB of 100,200 and 400 mJ/cm2,respectively,compared to 9.24%±0.97%in unirradiated cells (all P<0.05).Conclusions The expression of Gadd45α is increased in HaCaT cells after exposure to NB-UVB,and Gadd45α may be involved in the NB-UVB-induced suprression of cell proliferation of and cell cycle arrest in HaCaT cells.

Plasma endothelin-1 (ET-1),von Willebrand factor ( vWF) and fibrin D-dimer (D-D) were determined in 14 children with schnlein-henoch purpuric nephritis (SHN),17 children with schnlein-hen och purp ura (SHP, no abnormal finding in the examination of the urinary system) and 12 children as normal controls, respectively. The results showed that plasma ET-1( 88.48±22.96ng/L),vWF(1.59±0.38U/ml) and D-D(1.45±0.39)mg/L in the SH N group were all significantly higher than those in both of the control group (4 3.73±17.89)ng/L, (0.99±0.3)U/ml and (0.28±0.23)mg/L and the SHP group (57. 54±20.92)ng/L, (1.5±0.31)U/ml and (0.64±0.34)mg/L although no significa ntly difference in the levels of vWF was observed between SHN and SHP groups. It was noticed that the levels of three parameters decreased significantly in the SHN g roup after treatment (all P＜0.01). There was a positive correlati on between the levels of plasma ET-1 and D-D with serum creatinine (all P＜0.01). It is suggested that excessive ET-1 induced by endothelial dam age of renal vessels, intravascular coagulation and secondary fibrinolysis are p robably involved in the process of renal damage.

Objective To predict the effectiveness of gentamicin combined with trisodium citrate for locking solution in preventing catheter-related bloodstream infection.Methods This is a retrospective study,ten kinds of common pathogens in catheter-related bloodstream infections were selected from medical intensive care unit (n =9) and cardiac care unit (n =1) between July 2011 and July 2012,and the diffusion method was used to analyze the inhibitory effect of gentamicin combined with trisodium citrate against tested pathogens.Results When trisodium citrate was tested alone,a certain antimicrobial activity could be detected from 10％ trisodium citrate,only Staphylococcus aureus and Staphylococci haemolyticus were inhibited,and then Enterococcus faecium was inhibited by 30％ trisodium citrate.Compared with trisodium citrate,gentamicin showed stronger antimicrobial activity.Staphylococcus aureus,Staphylococci haemolyticus,Enterococcus faecium and Escherichia coli could be inhibited by 0.32 g/L gentamicin and the antimicrobial activity was enhanced by increasing concentrations.The maximum activity was in 5 g/L gentamicin with 7-17 mm diameters.However,the antimicrobial activity of gentamicin didn't increase when combined with trisodium citrate,especially in 4％ trisodium citrate,the Staphylococci haemolyticus was not inhibited by all of the combinations with any concentration of gentamicin.In 0.32 g/L gentamicin,only the combination with 50％ trisodium citrate could inhibit the four kinds of pathogens (Staphylococcus aureus,Staphylococci haemolyticus,Enterococcusfaecium and Escherichia coli) with 8-21 mm diameters,while in 1 g/L,2 g/L,and 5 g/L gentamicin,these pathogens could be inhibited by the combination with only 10％ trisodium citrate,and the diameters were 5-24 mm,12-27 mm,and 17-28 mm,respectively.Conclusion Based on the data,gentamicin combined with trisodium citrate lock solution may play an important role in preventing catheter-related bloodstream infections caused by Gram-positive bacteria and Escherichia coli.
