Objective To explore the application of plastic pancreatic stents and/or nasal biliary drainage for choledocholithiasis patients having DSBC during Endoscopic Retrograde Cholangiopancreatography (ERCP).Methods Retrospective analysis on clinical data of 57 ERCP cases aiming at choledocholithiasis patients having DSBC from January 2010 to December 2015 has been carried out. According to the guide wire cannulation in an operation, patients are divided into three groups, i.e. plastic pancreatic stents group, nasal biliary drainage group, and plastic pancreatic stents + nasal biliary drainage group, so as to observe the success rate of operation and the occurrence rate of postoperative complications, such as pancreatitis or hyperamylasemia, as well as to compare the differences between the three groups.Results Out of the 57 patients receiving ERCP, 13 patients are in the plastic pancreatic stents group, with two successful operations (15.4%), one case of hyperamylasemia (7.7%), two cases of postoperative pancreatitis (15.4%), one case of fever (7.7%) and one case of hemorrhage (7.7%); 20 patients are in the nasal biliary drainage group, with 20 successful operations (100.0%), no occurrence of hyperamylasemia or postoperative pancreatitis or other complications including hemorrhage and fever; 24 patients are in the plastic pancreatic stents + nasal biliary drainage group, with 19 ERCP operations succeeded at the first attempt (79.2%) and 5 ERCP operations succeeded at the second try (20.8%), as well as 4 cases of hyperamylasemia (16.7%), 2 cases of hemorrhage (8.3%) , no occurrence of fever cases and postoperative pancreatitis. In comparison between the three groups, the occurrence of postoperative pancreatitis and successful rate of operation show a significant difference.Conclusion By adopting plastic pancreatic stents and/or nasal biliary drainage for patients having a dififcult selective biliary cannulation during ERCP, the success rate of operation can be improved, and the occurrence of pancreatitis can also be reduced.

By using the method of clonal analysis the evidence to prove that Hemophagocytic syndrome (HPS) is reactive or malignant was investigated to probe into the pathogenesis of HPS and its relations with clinical prognosis. The macrophages abnormally proliferated in bone marrow were isolated. Electrophoresis analysis was made after DNA extraction, enzyme restriction of human ardrogen receptor (HUMARA) genetic locus, and PCR amplification. In the 9 specimens, clonal proliferation was found in 2 cases and nonclonal proliferation in 7. Among the 7 cases of nonclonal proliferation, 3 were voluntarily discharged without clinical outcome, 2 cases fully recovered after 2-3 week treatment of large dose gamma globulin intravenous drip and hormone therapy, 1 case died at the 43th day after the hormone and anti-infection therapy, and one case was found to have granular leukoblast in peripheral blood after 3 weeks and diagnosed as having M2a after bone puncture. For the two patients with clonal proliferation, one obtained remission after chemotherapy and the other was died after 32 days without chemotherapy. It was concluded that there do exist clonal or malignant proliferation in HPS, so not every case is reactive.

Objective:To analyze the correlation of single nucleotide polymorphisms ( SNP) of ATP binding cassette transporter A1 gene (ABCA1) and lower extremity atherosclerotic disease (LEAD). Methods: The clinical data and peripheral blood were col-lected from 630 participants (314 LEAD cases and 316 normal controls) in Han population of Minnan. The 9 SNP genotypes in the ABCA1 gene were detected by Sequenom MassArray. Results:Among the 9 SNP genotypes, rs2980083 was rejected because it wasn' t in accordance with Hardy-Weinberg equilibrium. Obvious linkage disequilibrium was found between rs2066714 and rs2066715, rs1800976 and rs2246293, rs2246293 and rs2980083, and rs1800976 and rs2980083(D′>0. 9,r2 >1/3). There were no significant differences (P>0. 05) in 6 haplotypes of ABCA1 gene groups between the LEAD cases and the normal controls. No significant differ-ences (P>0. 05) were found in frequency distribution between the LEAD cases and the normal controls in 8 SNP according to the re-sults of genotype statistics. There was no onset risk of LEAD according to the gene logistic regression analysis. Conclusion:The SNPs of rs10124755, rs2980083, rs1800976, rs4149341, rs2066714, rs2066715, rs2066716, rs2230808 and rs2246293 might not correlate with the susceptibility of LEAD in Han population of Minnan.

Apoptosis and autophagy are common life phenomenon in various cells, which widely involve in physiological and path-ological processes, and interact with one another by many factors and multiple pathways. This intricate relationship runs through a vari-ety of cardiovascular diseases, and plays an important role in the occurrence, development and prognosis of many cardiovascular disea-ses. The effects of apoptosis and autophagy and their interrelationship in cardiovascular diseases were reviewed and summarized in this paper.

Human cytomegalovirus (HCMV) late mRNA expression in megakaryoblast and in turn the pathogenesis of idiopathic thrombocytopenic purpura (ITP) patients with HCMV infection, and effectiveness of ganciclovir were investigated. Colony forming unit-megakaryocytes (CFU-MK) of 46 ITP patients with HCMV infection were incubated from patients' bone marrow mononuclear cells (MNC). Reverse transcriptase-polymerase chain reaction (RT-PCR) was subsequently used for CFU-MK for HCMV-late mRNA detection. Ganciclovir therapy was given to both HCMV-late mRNA positive and negative groups for comparison of therapeutic effectiveness. The results in 19 of 46 CFU-MK culture cells specimens with positive HCMV-DNA by PCR or positive CMV-IgM by enzyme linked immunosorbent assay (ELISA) in the correspondent serum of peripheral blood were positive for HCMV-late mRNA. Sixteen out of 19, patients with positive HCMV-late mRNA CFU-MK had a positive response to ganciclovir. Amongst 27 patients with negative HCMV-late mRNA CFU-MK, only 4 positive responders to ganciclovir therapy were observed. Curative effectiveness of ganciclovir in HCMV-late mRNA positive group was significantly higher than that in HCMV-late mRNA negative group (P<0.01). It was suggested that HCMV could directly infect CFU-MK, which might be one of the mechanisms responsible for HCMV related ITP. The ganciclovir is an effective therapy in resulting in the increases in thrombocyte in the ITP patients whose HCMV- late mRNA was positive in their CFU-MK.
