Objective To evaluate the diagnosis of ureteral stone by helical CT. Methods 25 patients with acute flank pain. hematuria and suspected of ureteral stone on B ultrasonography yet with negative,KUB and IVU underwent helical CT scanning. Results 24 cases were found to have ureteral stone by helical CT,the accurate rate being 96%.Three cases were fond to have Hydronephrosis,Ureteral dilation,Edema periureteric and secondary signs of ureteral obstraction. Conclusions Helical CT is safe,quick and accurate in diagnosing ureteral stone.

Objective To explore the value of laparoscope in the treatment of biliary leak after laparoscopic cholecystectomy (LC). Methods 16 cases of biliary leak after LC from August 1996 to May 2001 were reviewed retrospectively. Results 14 patients with biliary leak without bile duct injury were operated on under laparoscope. 2 patients with biliary leak and bile duct injury were converted to open operation. Conclusions Laparoscope can confirm reasons of biliary leak and shorten hospitalization time of patients with biliary leak without bile duct injury.

Objective To try different concentrations of nicotine promotes the apoptosis of human umbilical vein en-dothelial cells and its mechanism .Methods Human umbilical vein endothelial cells were cultured .According to the concentration of nicotine , grouped as 10 -6 , 10 -7, 10 -8 mol/L, and control.After 24 h of nicotine treat-ment, proliferation/activity were tested by CCK-8 assay;Annexin V-FITC fluorescence staining detects the apoptot-ic cells.Western blot detects the expression of protein Bax , Bcl-2 and PARP-1, to study the mechanism of apopto-sis.Results Compared with control group , in 10 -6 ,10 -7 mol/L groups the proliferation/activity of HUVECs de-creased ( P<0.05 ) .And the number of apoptotic cells increased ( P<0.01 ) .The target proteins expression of 10 -6、10 -7 mol/L groups were changed as follow: Bax increased ( P <0.01 ) , Bcl-2 decreased ( P <0.01 ) and PARP-1 increased ( P<0.01 ) .Conclusions Nicotine may promote the apoptosis of vascular endothelial cells , which accelerates the development of atherosclerotic disease .

Thanks to the three decades of reform and opening up,hospitals in China have made tremendous achievements in their development,yet facing new ehallenges as well.to address these challenges,there is an urgent need for these hospitals to further their reform under the guideline of the scientific concept of development.This will help them strengthen their hospital culture,quality control,technology,human resources development,and their leadership,in order to achieve a better and faster growth,better serving the role to build a harmonious socialist society.

Objective: To investigate the effects of Ginkgo biloba extract 50 (GBE50) preconditioning on contents of inflammation-related cytokines in rats with myocardial ischemia-reperfusion. Methods: Fifty-eight SD rats were divided into sham-operated group, untreated group, Salviae miltiorrhizae (SM) injection group and low-, medium- and high-dose GBE50 groups. After intragastric administration for 7 d, the left anterior descending (LAD) coronary artery was occluded for 30 min followed by 60-min reperfusion to induce ischemia-reperfuion injury. Myocardium histopathologic change was observed by HE staining under a light microscope; myeloperoxidase (MPO) activity in myocardium was measured by colorimetric detection; tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and IL-8 were detected by radioimmunoassay; IL-4 and IL-10 were tested by enzyme-linked immunosorbent assay (ELISA). Results: Compared with untreated group, rats in medium-dose GBE50 group had lower inflammatory reaction and MPO activity (P<0.01). GBE50 also decreased the content of IL-6 (P<0.05, P<0.01) and increased the content of IL-4 in myocardium (P<0.05, P<0.01) as compared with the untreated group. The content of TNF-alpha in myocardium in the medium-dose GBE50 group was lower and IL-10 was higher than those in the untreated group, but without significant differences. Conclusion: GBE50 can decrease the content of IL-6 and increase the content of IL-4 in myocardium after ischemia-reperfusion injury. It suggests that GBE50 can regulate the inflammatory reaction after ischemia-reperfusion injury via inhibiting inflammatory cytokines and promoting anti-inflammatory cytokines.

Objective To investigate the potential effect of Lactobacillus acidophilus (L. acidophilus) on prevention and treatment of neonatal mice infected with human rotavirus (HRV). Methods Sixty 4-day-old kunming mice were randomly divided into control group. HRV infected group, L. acidophilus pretreated group (treated before HRV infection ) and L. acidophilus treated group(treated after HRV infection). The manifestation and pathological changes in small intestine of neonatal mice were observed. The HRV antigen in the feces and intestines were measured by ELISA and fluorescent-focus assay, respectively. Results The severity and duration of diarrhea as well as mortality in L. acidophilus pretreated group and treated group were lower than those in HRV infected group. The duration of HRV-antigens shedding following infection was considerably prolonged in HRV infected group compared to that in L. acidophilus pretreated group and treated group. Furthermore, decreased expression of HRV antigen and little pathological changes in intestinal mucosa were found in L. acidophilus pretreated group and treated group when compared with HRV infected group. Conclusion L. acidophilus may be used as an alternative approach for the prevention and treatment of neonatal mice infected with HRV.
