Objective To summary our experiences on the clinical management of early complications caused by ureteroscopy and pneumatic lithotripsy. Methods From May 2002 to December 2007,totally 660 patients received ureteroscopy and pneumatic lithotripsy in our hospital,25 of them had surgical complications. Their clinical data were analyzed retrospectively. Results Among the 25 cases,22 patients had ureteral perforation,2 had ureteral disruptions,and 1 showed pelvic hematoma owing to ureteral perforation and injury to the ovary vein. Of the 22 cases of ureteral perforation,13 patients received lithotripsy and placement of a double J stent into the renal pelvis via the perforation site;and 4 patients underwent repair of the ureter. The other 5 of the 22 cases refused open surgery,and showed symptoms of urinary extravasation,loin pain,fever,or hematuria postoperatively;PCN was successfully completed in 3 of them but failed in the other 2,who underwent open surgery afterwards. For the 2 patients with ureteral disruptions,ureteroureteral anastomosis was performed. And in the case of pelvic hematoma,we carried out open surgery to ligate the bleeding vessels. All of the 25 patients were cured and discharged from hospital prosperously. The double J stent was withdrawn in 2 months after the operation,and 1-year follow-up showed no ureteral stenosis or obstruction by intravenous pyelography. ConclusionsPrimary management of ureteral injury by indwelling double J stent or percutaneous nephrostomy results in significantly deceased rate of re-operation. Conversion to open surgery timely can stop the incidence of other severe complications.

Objective To evaluate the efficacy of dural tenting suture and epidural drainage in craniotomy. Methods In 145 cases of intracranial lesions, dural tenting suture and epidural drainage were performed to prevent epidural hematoma. Results Postoperative computed tomography (CT) showed no epidural hematoma required surgery in both groups. Conclusion Both dural tenting suture and epidural drainage are effective in preventing epidural hematoma. Hemostasis is the key step. Dural tenting suture without epidural drainage relieves psychological stress. It decreases the risk of intracranial infection and avoids some unusual complications.

Objective To explore the therapeutic mechanism of blood- activating and blood- stasis- removing (BABAR) therapy for polycythemia vera (PV).Methods Ten first- visit or un- relieved outpatients and inpatients were treated with BABAR therapy for 12 weeks. Healthy volunteers served as the normal control. Before treatment and 1, 4, 8 and 12 weeks after treatment, the apoptotic rates of bone marrow mononuclear cells (BMMC) was analyzed with the TUNEL method. The expression of bcl- 2 and p53 was observed by the method of immunohistochemistry and their mRNA expression by the method of hybridization in site.Results One, four and eight weeks after treatment, the apoptotic rates of BMMC was increased as compared with those before treatment (P 0.05).The gene expression level of Bcl- 2 and p53 and their RNA expression level in the patients before treatment were higher than those in the normal control(P

Objective To construct stable chromokinesin KIF4A knockdown gastric cancer cell lines (SGC-7901) and study the mitotic spindle midzone formation in these cells.Methods Short hairpin RNA (shRNA) expression plasmids of pGPU-GFP-shKIF4A,pGPU-GFP-shNC specific targetting KIF4A and non-sense DNA sequences were constructed respectively and then transfected into SGC-7901 cells.The cells were cultured in selection medium containing G418 to form single clones.Stable KIF4A shRNA expressing SGC-7901 cells were picked up under an fluoroscent microscope and identified by Western Blot.The spindle midzone in these cells was analyzed after immunofluorescence staining.Results Three cell lines stably expressing KIF4A shRNA and one with shNC were successfully constructed.Compare to the control cell line,KIF4A knockdown cell lines represented remarkable elongation of spindle midzone and the less the KIF4A,the longer spindle midzone.Conclusions Stable KIF4A knockdown SGC-7901 cell lines were successfully constructed that can serve for further study of KIF4A ' s function and its role in proliferation and development of gastric cancer.

OBJECTIVETo study the effect of allitridum on rapidly delayed rectifier potassium current (IKr) in HEK293 cell line.

METHODSHEK293 cells were transiently transfected with HERG channel cDNA plasmid pcDNA3.1 via Lipofectamine. Allitridum was added to the extracellular solution by partial perfusion after giga seal at the final concentration of 30 µmol/L. Whole-cell patch clamp technique was used to record the HERG currents and gating kinetics before and after allitridum exposure at room temperature.

RESULTSThe amplitude and density of IHERG were both suppressed by allitridum in a voltage-dependent manner. In the presence of allitridum, the peak current of IHERG was reduced from 73.5∓4.3 pA/pF to 42.1∓3.6 pA/pF at the test potential of +50 mV (P<0.01). Allitridum also concentration-dependently decreased the density of the IHERG. The IC50 of allitridum was 34.74 µmol/L with a Hill coefficient of 1.01. Allitridum at 30 µmol/L caused a significant positive shift of the steady-state activation curve of IHERG and a markedly negative shift of the steady-state inactivation of IHERG, and significantly shortened the slow time constants of IHERG deactivation.

CONCLUSIONAllitridum can potently block IHERG in HEK293 cells, which might be the electrophysiological basis for its anti-arrhythmic action.
