Objective To evaluate the curative effect,safety,advantages and disadvantages of helix hydro-jet and holmium laser lithotripsy in the treatment of intrahepatic bile duct stones.Methods 158 patients of intrahepatic bile duct stones were divided into helix hydro-jet group (n =82) and helix hydro-jet group (n =76).Time of lithotripsy,frequencies of lithotripsy,residual stone,intraoperative hemorrhage,postoperative hemorrhage,stone recurrence rate,postoperative fever,and therapeutic efficacy were compared between the two groups.Results There was no significant difference between the two groups on frequency of lithotripsy,residual stone rate and stone recurrence rate (P > 0.05) ; whereas intraoperative washing normal saline (2 300 ± 275) ml vs (2 850 ± 331) ml,(P =0.002),the time of lithotripsy (54.2 ± 15.3) min vs (38.1 ± 12.7) min,P =0.041,intraoperative hemorrhage (19 cases vs 29 cases,P =0.041),Intraoperative analgesia (2 cases vs 9 cases,P =0.032),postoperative hemorrhage (11 cases vs 21 cases,P =0.037),and postoperative fever (30 cases vs 62 cases,P =0.027) had significant differences(P < 0.05).Conclusions Both helix hydro-jet and the holmium laser lithotripsy is safe and effective for the treatment of intrahepatic bile duct stones.Holmium laser is more efficient than Helix Hydro-jet,while helix hydro-jet is safer than holmium laser in lithotripsy.

Objective:
: This study analyzed the influence of p120-catenin (catenin [cadherin-associated protein], delta 1 [CTNND1]) on the malignant characteristics of glioma and elucidated the potential underlying mechanism.
Methods:
: The p120 expression level was assessed in the brain tissues of 42 glioma patients and 10 patients with epilepsy by using the immunohistochemical method. Meanwhile, quantitative polymerase chain reaction (QT-PCR) technology was employed to assess the expression of p120 in the brain tissues of 71 glioma patients and 13 epilepsy patients. LN229, U251, and U87 glioma cells were used for in vitro analysis and categorized into four treatment groups : siRNA-blank control (BC) group (no RNA sequence was transfected), siRNA-negative control (NC) group (transfected control RNA sequences with no effect), and siRNA-1 and siRNA-2 groups (two p120-specific interfering RNA transfection). p120 expression in these treatment groups was quantified by western blotting assay. The migratory and invasive capabilities of glioma cells were studied by wound healing assay and Transwell invasion assay, respectively, under different treatment conditions. MTT (3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide) assay and cell cycle and apoptosis assay were used to determine glioma cell proliferation and apoptosis, respectively. Enzymelabeled assay was performed to measure intracellular calcium ion concentration. Immunofluorescence assay was performed for determining microtubule formation and glioma cell distribution.
Results:
: Brain tissues of the glioma group exhibited a remarkable increase in the p120 expression level as compared to brain tissues of the nontumor group (p<0.05). Furthermore, a strong positive correlation was noted between the malignancy degree in glioma brain tissues and p120 expression in Western blotting (r=0.906, p<0.0001) and QT-PCR (F=830.6, p<0.01). Compared to the BC and NC groups, the siRNA transfection groups showed a significant suppression in p120 expression in glioma cells (p<0.05), with a marked attenuation in the invasive, migratory, and proliferative capabilities of glioma cells as well as an increase in apoptotic potential (p<0.05). Enzyme-labeled assay showed a remarkable increase in calcium concentration in glioma cells after siRNA treatment. Immunofluorescence assay revealed that the microtubule formation ability of glioma cells reduced after siRNA treatment.
Conclusion
: p120 has a pivotal involvement in facilitating glioma cell invasion and proliferation by potentially modulating these processes through its involvement in microtubule formation and regulation of intracellular calcium ion levels.
