Aim To investigate the role of chemokine-like factor 1 ( CKLF1 ) in SH-SY5 Y cell migration and its molecular regulatory mechanism. Methods SH-SY5Y cells were stimulated with CKLF1 for 0. 5 h, 2 h, 8 h and 24 h, respectively. The migration distance and the percentage of migration cells were recorded by CELLocate analysis. The phosphorylation of focal ad-hesion kinase ( FAK) at Tyr-397 site was detected by Western blot analysis. By chemotaxis assays, we con-firmed the chemotaxis of CKLF1. Furthermore, FAK inhibitor PF-573228 and PLCγ inhibitor U73122 were used for the research of molecular regulatory mecha-nisms involved. Results CKLF1 promoted cell migra-tion and induced a strong increase in the phosphoryla-tion level of FAK-pY397 , which were significantly at-tenuated by the presence of U73122 ( a specific inhibi-tor for PLCγ) . In addition, the chemotaxis of CKLF1 was obviously blocked by the FAK inhibitor PF-573228 . Conclusion CKLF1 induces SH-SY5 Y cell migration via PLCγ/FAK signaling pathway.

Phagocytic capacities of both dendritic cells (DC) and macrophages(M?) in the DC-enriched fractions isolated from rat spleen were comparatively observed under electron microscope. Experiments were divided into two groups: in vitro and in vivo. In group 1, candida albicans(CA), cock red blood cells (CRBC) and CRBC opsonized with rat antiserum against CRBC (OCRBC) used as phagocytic markers were incubated with the DC-enriched fractions for 1h at 37℃ separately in vitro. In group 2, colloidal carbon (CC) (india ink) and heat killed Candida albicans (HKCA) were injected in vivo. The animals were sacrificed 18h later and DC-enriched fractions were isolated from the spleens. The results are as follow: generally, in the cytoplasm of DC, no phagocytic markers were identified except a few of DC ingested a small amount of CC in vivo and few CA occationally in vitro, while M? under the same conditions, ingested a lot of the substances mentioned above. It indicates that spleen M? phagocytose actively either to immunogenic or non-immunogenic, opsonized or non-opsonized particles (especially to opsonized particles), while DC in the same preparations are not.

Objective To evaluate the endoscopic managements of acute cholangitis of severe type (ACST) accompanied with multiple organ dysfunction syndrome (MODS). Methods A total of 122 ACST patients accompanied with MODS from January 2000 to October 2008 underwent endoscopic treatment in two time periods. In critical phase, emergent endoscopic retrograde cholangiopancreatography (ERCP) plus en-doscopic naso-biliary drainage (ENBD) were performed to correct critical situation of the patients. After sta-bilization, endoscopic sphincterotomy (EST) plus stone removal, EST plus stent placement, or laparoscopy was performed according to the causes of ACST. Results Emergent endoscopic managements succeeded in all patients of critical phase. At third day post-operation, a reduction in white blood cell count, serum total bilirubin, body temperature, and rate of patients with shock, mental symptoms and purulent bile juice was a-chieved. Recovery rate of dysfunction organs was 60.2% at one week after emergent procedure, and 82. 6% at 2 weeks post-operation. Selective EST plus stone removal was performed in 36 patients with a success rate n one session at 91.7%. Laparoscopic cholecystectomy was performed in 85 patients with a success rate of 95.3%. Stent was placed in 16 patients with an effective rate of 81.3% at 3 months post the procedure. No severe complication or death occurred during the whole therapeutic course. The 6-month survival rate of 10 cancer cases was 70%. Conclusion Therapeutic ERCP plus ENBD is the first choice for acute severe cholangitis accompanied with MODS, while EST plus biliary lithotomy, or EST plus stent placement, or com-bined laparoscopy are ideal methods for subsequent treatment.
