BACKGROUND: There are a variety of methods for establishing periprosthetic osteolysis animal model, and the models established by different methods and with different animals have their own characteristics.OBJECTIVE: To review the research profiles of the periprosthetic osteolysis and the characteristics of the various models, and to provide a reference for the related research. METHODS: The relevant articles on the periprosthetic osteolysis animal models were searched in PubMed from January 1999 to May 2017, with the key words of "animal model, osteolysis" in English by the computer. Similarly, Chinese Journal Full-text Database was retrieved for related articles published from January 1999 to May 2017, with the key words of "animal model, osteolysis" in Chinese. Articles that were unrelated to the periprosthetic osteolysis animal model were excluded. Classic and recently published articles were selected. RESULTS AND CONCLUSION: (1) The artificial induced animal models are the principal means to establish animal models of periprosthetic osteolysis and they have been widely used in the study of periprosthetic osteolysis pathogenesis, pathological process and treatment. (2) Small-animal models present many advantages: inexpensive to purchase, high physiological turnover, controlled source, homogenous and established genetic background. However, a limitation of these small-animal models is that the temporal pattern of osteolysis is different from the long-term osteolysis that occurs in patients. (3) The large animal model is more similar to the bone dissolution process around the human prosthesis, but the cost is high; the breeding is difficult; the operation requirement is hard. Thus, its widespread use is limited. (4) Furthermore, innovative models that combine the advantages of both are also constantly explored. Overall, the selection of models should be based on research conditions and needs to be considered.

The cardiovascular circulation feedback control treatment instrument (CFCTI) is an automatic feedback control treatment system, which has the function of monitoring, alarming, trouble self-diagnosis and testing on the line in the closed loop. The instrument is designed based on the successful clinical experiences and the data are inputted into the computer in real-time through a pressure sensor and A/D card. User interface window is set up for the doctor's choosing different medicine. The orders are outputted to control the dose of medicine through the transfusion system. The response to medicine is updated continually. CFCTI can avoid the man-made errors and the long interval of sampling. Its reliability and accuracy in rescuing the critical patients are much higher than the traditional methods.

To investigate the influence of Anxin granules combined with tirofiban on acute myocardial infarction (AMI) Patients after elective percutaneous coronary intervention (PCI). One hundred and twenty AMI patients were randomly divided into treatment group and control group. The patients in the two groups were all given Tirofiban 30mins before PCI . The treatment group was added Anxin granules 30 mins before and after PCI. Tissue factor (TF) and von willebrand factor (vWF) were tested at 6 hours after operation. Syndromatology alteration of traditional Chinese medicine (TCM) and bleeding complications were observed at 4 weeks after operation. Both TF and vWF at 6 hours after operation of the treatment group was lower than the control group significantly (P < 0.01), while the condition of myocardial ischemia at 90 mins after operation of the treatment group was better than control group with significance. The syndromatology alteration of TCM especially spontaneous perspiration and hypodynamia of the treatment group were improved significantly compared to control group 4 weeks after operation. All patients in both groups had no bleeding complications and thrombopenia. The study suggests that Anxin granules combined with tirofiba can improve the clinical efficacy and the endothelial function of AMI patients after PCI with no increase in bleeding events.

Objective To analyze the molecular characteristics of the newly isolated two Japanese encephalitis virus strains(JEV) in Wuhan. Methods The mosquitoes were collected in Wuhan from April to October in 2009. The envelope (E) protein gene of JEV was detected using RT-PCR and sequenced.Sequence comparisons and phylogenetic analysis were conducted using DNAstar and MegAlign. Results Two Japanese encephalitis virus (JEV) strains (WHJX09-9, WHJX09-10 ) were isolated from Culex tritaeniorhynchus among 16 mosquito pools and identified as genotype I. The result showed that the homology of the two strains was 98. 9% in nucleotides and 100% in deduced amines. The comparison between the new genotype 1 JEV strains and live attenuated vaccine strain SA14-14-2 in E gene showed that the homology of nucleotide sequence was 87.4% and 87.9% ,the homology of amino acid was 96. 9% (totol 15 amino acid were different) in E gene. The mutation sites of amino acid distributed among three different coding domain,but no antigen binding site and neurotoxin-involved site of amino acid were changed. Conclusion Wuhan had appeared a new genotype of JEV which was different from the former strain isolated in Wuhan,the new JEV strains still had neurotoxicity but had high homology with the vaccine strains adopted in Wuhan. The vaccine could still be adopted to prevent Japanese encephalitis if steps were take to eradicate mosquitos at the same time. laboratory surveillance were also an important task to build an early-warning mechanism against JEV.

OBJECTIVETo verify the obtained immunogenic membrane antigens candidate of pancreatic cancer in the performed research.
METHODSPancreatic cancer cell line SW1990 membrane protein underwent immunoblot with serum IgG purified from clinically collected sera of 66 pancreatic cancer patients. Number 3 and number 8 positive dots of immunoblot were identified by MALDI-TOF mass spectrometry and peptide mass fingerprinting matching. The candidate membrane antigens were further validated in cell lines by RT-PCR, real-time PCR and Western blot, and their different expression level of gene and protein in pancreatic cancer cell lines were contrastly studied.
RESULTSNumber 3 and number 8 positive dots were identified as: voltage-dependent anion channel (VDAC3) and catechol-o-methyltransferase (COMT). RT-PCR, real-time PCR and Western blot showed that gene and protein of VDAC3 and COMT were expressed in the pancreatic cancer cell line SW1990, AsPc and P3 respectively.
CONCLUSIONVDAC3 and COMT might be the candidate immunogenic membrane antigens of human pancreatic cancer, and their gene and protein are differently expressed in the pancreatic cancer cell line SW1990, AsPc and P3.

OBJECTIVETo investigate the causes and treatment of postoperative hyperbilirubinemia after orthotopic liver transplantation.
METHODSClinical data of 368 cases of orthotopic liver transplantation patients from the First Affiliated Hospital of Sun Yat-sen University between 2004 and 2005 were analyzed retrospectively.
RESULTSThree hundred and sixty-eight patients experienced 396 incidents of hyperbilirubinemia, including 183 incidents of preoperative hyperbilirubinemia (46.2%), 46 incidents of ischemia-reperfusion injury (11.6%), 36 incidents of acute rejection (9.1%), 78 incidents of biliary complications (19.7%), 24 incidents of blood vessel complications (6.1%), 23 incidents of recurrence of the primary disease (5.8%) and 6 incidents of tacrolimus (FK506) toxicity (1.5%). The comprehensive management targeted to the etiology and symptoms were applied to all patients with hyperbilirubinemia.
CONCLUSIONHyperbilirubinemia is a common clinical manifestation after liver transplantation with multiple and complicated causes. The key point for successful treatment is to identify the causes. To reach the aim of treatment and obtain long-term survival of the recipients, it is very important to make a correct diagnosis and give reasonable therapeutic regimens as soon as possible.
