Objective To investigate the effects of macrophage inflammatory protein-1α (MIP-1α) combined with molecule 4-1BB L on the tumorigenicity of hepatocellular carcinoma cells in vivo. Methods Mouse MIP-1α (mMIP-1α) expressed Hepa 1-6 cells were transfected with m4-1BBL recombinant retrovirus, the anti-histidinol cells clones were selected and amplified. The expression of m4-1BB L was confirmed by flow cytometry. The growth curve of Hepa 1-6 cells transfected with mMIP-1α and m4-1BBL alone or together was drawn and compared. C57B/L Mice were randomly divided into 7 groups, 9 mice in each group, injected with mMIP-1α+m4-1BB L Hepa 1-6 cells, m4-1BB L Hepa 1-6 cells, mMIP-1α Hepa 1-6 cells, Hepa 1-6 cells, pLXSHD Hepa 1-6 cells or PBS respectively. The tumorigenicity of hepatocellular carcinoma cells and the mice survival rate were compared between each groups. Results Hepa 1-6 mMIP-1α+m4-1BB L cells which expressed both mMIP-1α and m4-1BB L were successfully established. The expression of mMIP-1α and m4-1BB L alone or together did not affect the growth curve of Hepa 1-6 cells. Observed for 5 weeks, no tumor developed in Hepa 1-6 mMIP-1α+m4-1BB L injected mice. The tumorigenicity of Hepa 1-6 mMIP-1α+m4-1BB L was lower than that of Hepa 1-6 mMIP-1α or Hepa 1-6 m4-1BB L in vivo. The survival rate of Hepa 1-6 mMIP-1α+m4-1BBL injected mice(9/9) was higher than that of Hepa 1-6 m4-1BB L injected mice (6/9)or Hepa 1-6 mMIP-1α injected mice (1/9). Conclusion Chemokine MIP-1α combined with costimulatory 4-1BB L lowered the tumorigenicity of hepatocellular carcinoma cells in vivo, and prolonged the mice survival period.

OBJECTIVE:To provide reference for vancomycin-induced neutropenia adverse reactions/adverse events in clinical diagnosis. METHODS:With a case of children with neutropenia treated by long-course and large-dose vancomycin,PubMed and CNKI were retrieved to collect related literature and the literature was analyzed. RESULTS:Neutropenia may be associated with vancomycin,based on causality criterion of adverse reaction in China. CONCLUSIONS:Vancomycin-induced neutropenia in chil-dren is most likely associated with prolonged exposure induced by infusion,vancomycin dosage should be reduced or stopped,and routine blood and plasma concentration should be closely monitored.

Objective To study the clincial effectiveness and safety of endoscopic sphincteropapillotomy combined with balloon dilation for decompensated cirrhosis accompanied with choledocholithiasis.Methods Data of 79 cases of decompensated cirrhosis patients with choledocholithiasis who underwent limited endoscopic sphincterotomy plus endoscopic papillary balloon dilation (ESBD,the ESBD group) and 42 cases who underwent endoscopic papillary balloon dilation(EPBD,the EPBD group)were retrospectively analysed and compared for complete stone clearance rate,one-time stone clearance rate and complications.Results The rate of complete stone clearance and one-time stone clearance were 94.9％ (75/79) and 77.2％ (61/79)in ESBD group,and those were 88.1％ (37/42) and 59.5％ (25/42) in EPBD group respectively.The rate of complete stone clearance was a little higher in ESBD group than that in EPBD group.In ESBD group,ERCP-related bleeding occurred in 3 patients (3.8％),post-ERCP hyperamylasemia in 3 (3.8％)and post-ERCP pancreatitis in 2 (2.5％) ; while in EPBD group,post-ERCP hyperamylasemia occurred in 8 patients(19.0％),post-ERCP pancreatitis in 6(14.3％) and ERCP-related bleeding did not occur.There were no significant difference in ERCP-related bleeding between ESBD group and EPBD group (P =0.551).However,the rates of post-ERCP pancreatitis and hyperamylasemia in ESBD group were significantly lower than those in EPBD group(P ＜ 0.05).Conclusion ESBD is a safe and effective procedure for choledocholithiasis accompanied by decompensated cirrhosis,with several advantages over EPBD in terms of higher one-time stone clearance rate,reduced risk of post-ERCP pancreatitis and hyperamylasemia,and without noticeable increase in the risk of bleeding related to ERCP.

As the existing electrical field method for colon hollow structure virtual eversion is time consuming, a new faster method is presented here to overcome this disadvantage. In the new method, the cross section we used is composed of an orthogonal section and an electrical field section rather than the electrical field section only. We have applied this new method to a series of CT data of a patient for virtual eversion. The result shows that the time cost by using the fast method is only about 1/6 of the existing method, and the image quality is also acceptable.
