Objective To research the occurrence of liver cirrhosis and portal hypertension splenectomy treatment,and analyze the risk factors for postoperative complications.Methods Retrospectivly analyzed the clinical data of 390 liver cirrhosis cases from March 2009 to May 2013 who were admitted to department of digestion and vascular surgery,First Affiliated Hospital of Xinjiang Medical University,for splenic resection.Child classification,diabetes,amount of fluid drainage,drainage time,blood loss,emergency surgery,combined with other surgery were alalysised by Logistic regression.Results Among three hundred and ninty cases of splenectomy patients,liver cirrhosis complications occurred in 53 cases (53/390,13.58％).In these 53 cases,45 cases combined diabetes,Child grade A 12 cases,B 22 cases,C 19 cases,and theirs 24 hours drainage volume was (422.45 ±297.09) mL,drainage time was (4.96 ± 1.48) d,blood loss was (874.72 ± 106.19) mL,K value was 0.10 ±0.06,R15 value was 0.27 ±0.016,albumin concentration was (30.09 ±6.87) g/L,Among the rest 337 cases,228 cases were combined diabetes,Child grade A 134 cases,B 129 cases,C 74 cases,and theirs 24 hours drainage volume was (234.06 ± 171.15) mL,drainage time was (3.18± 1.72) d,blood loss was (261.90±98.27) mL,K value was 0.14 ± 0.09,R15 value was 0.19 ± 0.015,albumin concentration was (32.51 ±5.58) g/L.Multivariate regression analysis had indicated that Child grade,drainage volume of 24 hours,drainagetime,and K value were independent factors affecting the occurrence of complications.Conclusion The major risk factors of incidence happen on postoperative complications in cirrhosis and portal hypertension splenectomy are high Chill grading,draining a long time,and 24 hours blood loss,and k value.

Objective To observe the clinical effects of treating infantile viral myocarditis with Huangqi Injection united Vitamin C. Methods 60 patients with infantile viral myocarditis were randomly recruited into a control group and a treatment group, with 30 patients in each group. Both groups were given comprehensive therapies including rest, anti-infection, myocardium nourishment, etc. The treatment group was additionally treated with Huangqi Injection united Vitamin C on the basis of comprehensive therapies. Results The total effective rate of the control group and the treatment groups was 70.00% 96.67% respectively, the difference showing statistic significance (P<0.05) . Conclusion It was effective to treat infantile viral myocarditis with Huangqi Injection united Vitamin C.

Objective To observe the effect of treating infantile anaphylactoid purpura with self-made Huoxue Huayu decoction. Methods 68 cases with infantile anaphylactoid purpura ,were randomly recruited into a control group and a treatment group, with 34 cases in each group. The control group was taken Cetirizine, Prednisone, Rutin and Vitamin C orally. The treatment group was treated with self-made Huoxue Huayu decoction on the basis of treatment in the control group. Results The total effective rate of the control group and the treatment group was 82.35% and 94.12% respectively. As compared with the effective rate in the control group, the treatment group showed significant improvement. Conclusion It was effective to treat infantile anaphylaetoid purpura with Huoxue Huayu decoction.

Hepatic ischemia-reperfusion injury(IRI)is a critical problem of liver surgery,especially when comes to liver transplantation.Presently.there are no effective measures for diagnosis,prevention and therapy of IRI,as the mechanisms of IRI still remain unclear.This review summarizes several new hepatic ischemia-reperfusion markers related to cell signal transduetion pathway.including transcription factor STAT,HIF-1 and PPARs,transmission factor MAPK,membrane receptor TLR4 and PARs.and iNOS.Animal studies have indicated that IRI was ameliorated by activating or blockading these markers,which might serve as targets for diagnosis,prevention and therapy of IRI.

Objective To construct the eukaryotic expression vector of pprI gene from Deinococcus radiodurans R1 and investigate its radioresistant effects in eukaryotic cells.Methods A recombinant vector pEGFP-c1-pprI was constructed by DNA recombinant technique.The empty vector pEGFP-c1 and the pEGFP-c1-pprI were transferred into human lung epithelial cells Beas-2B by LipofectamineTM 2000,respectively.Then the infected cells were screened in order to develop a cell line with stable expression of pprI gene.Cell survival rate was tested by clone-forming assay.Cell cycle distribution and apoptosis were detected by a flow cytometry.The fluorescence intensity of reactive oxygen species (ROS) was observed by a fluorescent microscope.γ-H2AX foci in the irradiated cell was detected by immunofluorescence.Results The eukaryotic expression plasmid of pprI prokaryotic gene was constructed and PprI fusion protein was expressed in human lung epithelial cells successfully,and the cell line (2BG) with a stable pprI gene expression was established.After irradiation,the cell survival fraction of 2BG cells was significantly higher than Beas-2B cells so that the value of D0 、Dq and N of the survival curve were increased.Moreover,the fluorescence intensity of ROS and the number of γ-H2AX foci in 2BG cells were also lower than those of B eas-2B cells(F =16.73,19.47,6.94,P ＜ 0.05).Between these two cell lines,the apoptosis rate and cell cycle G2 arrest also had significant difference (F =139.73,237.92,P ＜ 0.05).Conclusions The pprI gene from Deinococcus radiodurans RI can be stably expressed in the eukaryotic cells and it allows the transferred cells to have a radioresistant function.

BACKGROUND:The biological substances fixed onto the implant surface, including specific proteins, enzymes, polypeptides, could promote the proliferation and differentiation of osteogenic cells in order to achieve a good osteogenic effect.
OBJECTIVE:To introduce the biological characteristics of the arginine-glycine-aspartic acid (RGD) peptides, cellbiological behavior and implant osseointegration in osteoporosis.
METHODS:Authors retrieved the relevant articles in PubMed database (January 1984 to January 2013), Wanfang database (January 2002 to December 2012) and CHKD database (January 2002 to December 2012) using the key words“RGD peptides, osteoporosis, bone marrow mesenchymal stem cells, osseointegration, osteoblast, induced differentiation”. Papers were included concerning the biological characteristics of RGD peptides, the biological behavior of cells and the bone-implant integration in osteoporosis.
RESULTS AND CONCLUSION:Osseointegration on the surface between implant and bone tissue can be further improved by grafting biological y active substance. Bionics modification, to simulate the extracellular matrix environment in vivo, can promote celladhesion and growth, which is an effective way to improve osseointegration and is also an important direction of research in the field of tissue engineering recently. The future research is focused on designing specific and efficient polypeptides and simple and effective fixation methods.
