Objective To explore the methods and curative effect of metallic self-expanding stent in inoperable malignant gas-troduodenal obstruction. Methods The data of 15 cases with gastroduodenal obstruction including 9 cases of carcinoma of head of pancreas and 6 cases of carcinoma of stomach were analyzed retrospectively. The operative procedures of the stent implanted and the tors accepted more radiation dose because the manipulation was under the fluoroscopy in a short distance and with a full field of view. sions, the postoperative eating habit and the development turnover of disease. The main death reasons were tumor transfer and sys-tem exhaustion. Conclusion To pay close attention to the details and main points of operative procedure is the key point to implant stent successfully for malignant gastroduodenal obstruction. The determinative factor to influence the curative effect is the develop-ment turnover of tumor.

To study the effect of wearing overnight orthokeratology ( OK) contact lens on corneal topography and tears in adolescents.METHODS: The diopter, corneal curvature, corneal surface regularity index ( SRl ) , tear break - up time ( BUT ) , Schirmer l test, and corneal fluorescent ( FL ) were recordedon 40 (80 eyes) adolescent myopia patients (mean age 13. 68±2. 32 years), who had worn OK contact lensfor more than 1 year, with mean spherical equivalent refraction -3. 61 ± 1. 48D before wearing OK contact lens. These indexes were tested and recorded before the patients' wearing OK contact lens and 5 times (1wk and 1, 3, 6, 12mo after the first wearing) during the patients' overnight wearing OK contact lens for 8~10 hours per day.RESULTS: Compared with pre - wearing, at post -wearing OK contact lens 12mo, the mean spherical equivalent refraction was apparently decreased from -3.61±1. 48D to -1. 39±1. 31D(P<0. 01). The corneal curvature was significantly flattened from 42. 29 ± 1. 55D to 40.13±1. 41D (P<0. 01). Mean SRl was increased from 0. 34± 0. 01 to 0. 37 ± 0. 01 ( P<0. 01 ). Mean BUT was decreased from 10. 39±2. 25s to 7. 26±1. 77s (P<0. 01). These indexes were stable at 1wk after wearing OK contact lens overnight and had no significant differences during the following (1, 3, 6, 12mo after wearing) tests (P > 0. 05 ). There were no significant differences on Schirmer▏test during the 12mo of OK wearing(P>0. 05). The cases of corneal fluorescent staining increased were mainly grade l, and the number of corneal staining grade l at 1 wk and 1, 3, 6, 12 mo after wearing were 15 eyes (18. 8%), 9 eyes (11. 3%),13 eyes (16. 3%), 9 eyes (11. 3%), and 12 eyes (15. 0%). BUT of corneal staining grade l wasdecreased significantly, compared with the BUT of corneal staining grade 0 during the 12mo of OK wearing (P<0. 05). CONCLUSlON: OK contact lens can significantly decrease the degree of myopia and K value of corneal curvature without changing tear volume. However, tear film stability weakens, which needs regular follow-up.

Objective:To investigate the existence of side population cells with the potency of stem cells in human gallbladder carcinoma cell line GBC-SD and the differences in ABCG2,Oct-4 and CD34 expression among SP cells,non-SP cells and GBC-SD cells.Methods:SP and non-SP cells were sorted from GBC-SD cells by fluorescence-activated cell sorting(FACS).The expression of ABCG2,Oct-4 and CD34 in SP cells,non-SP cells,and GBC-SD cells was detected by reverse transcription-polymerase chain reaction(RT-PCR),Western blot,flow cytometry(FCM)and immunofluorescence chemistry.Results:SP cells with stem cell potency were isolated from GBC-SD cells with a proportion of(0.64±0.08)%.The metastatic ability of SP cells was obviously higher than that of non-SP cells and GBC-SD cells(P<0.05).The expression of ABCG2 was significantly higher in SP cells than in non-SP cells and GBC-SD cells[(89.56±3.86)%vs.(1.32±0.49)%and(12.37±1.61)%,P=0.001].The expression of Oct-4 in these cells was(94.87±1.40)%,(88.16±2.34)%and(90.17±1.61)%,respectively(P>0.05).CD34 was neady absent in these cells on protein level[(1.78±0.51)%vs.(0.63±0.21)%and(0.96±0.381)%,P>0.05)],but it was highly expressed in non-SP cells and GBC-SD cells and absent in SP cells off mRNA leve;.Conclusion:SP calls which hava the potency of stem cells,exist in human gallbladder carcinoma GBC-SD cell line and have the phenotype of ABCG2+Oct-4+CD34-.

Objective To summarize our experience in treating abdominal aorta saddle embolism(ASE).Methods The clinical data of 21 cases of abdominal ASE were treated with Fogarty catheter and other(methods) during January 2000 to July 2006 were retrospectively assessed.Results After the blood flow was restored by operation,4 died in the postoperative early stage because of sudden cardiac asystole due to(hyperkalemia);in the late stage,6 died of multiple organ dysfunction syndrome socondary from acute renal(failure)(ARF).Eleven patients were cured.Of them,bilateral lower extremites were salvaged in 5 patients;and 6 patients received amputation.Ten patients were followed up,and the blood supply of the salvaged legs was good.Conclusions Early diagnosis and embotism removal are the key points to decrease the mortality and amputation rate of ASE.The intra-operative and post-operative prevention and management of(hyperkalemia) and ARF are important for reduction of mortality.

Objective:To evaluate the effect of short-time group psychological guidance on mental quality of college students. Methods:Designed the content of one day's psychological coach.600 college students received psychological coach successively.60 students were randomly chosen as the intervened group,who were treated with one-day group psychological guidance,while 60 students,who never attended the group psychological guidance,were chosen as control.Assessed and compared the mental quality of the intervened group and the control group with the Faith in People Scale (FPS),Personal Evaluation Inventory (PEI),Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale (SDS) on the day before or 1 and 12 weeks after coach.Results:There were no significant differences of the scale of FPS,PEI,SAS,and SDS between two groups before coach and there were significant differences between two groups after coach.Conclusion:Short-time group guidance is helpful to developing college students' ability in interpersonal contact and self-confidence and improving depression and anxiety.

Objective To explore virtual three-dimensional (3D)model for intravascular interventional devices,the method of preoperative simulation and its value in clinical work.MethodsThe virtual models including catheter,guide wire,stent and coil were established by using the 3D moulding software of 3D Studio MAX R3. The interventional preoperative simulation was performed on personal computer including 21 patients of cerebral aneurysm embolization ( anterior communicating artery 5,posterior communicating artery 10,middle cerebral artery 3,internal carotid artery 2,and vertebral artery 1 ),during interventional procedures,the surgeon relied on the simulation results for plastic micro-guide wire,catheter and the release of micro-coils and stents.Results( 1 ) All the virtual instruments and real instruments had similar shape,the overall tine for constructing virtual model was about 20 hours.The preoperative simulation took 50 to 80 minutes. (2) The simulation result of catheter insertion in the 18 cases had relevant value to guide micro-catheter,molding micro-guide wire tip,and shortened the operating time.For embolization,the simulation results of filling coil and releasing stent were similar to surgical results in 76% of the patients (16/21).(3)For teaching and training,93% (38/41) of doctors in training believed that preoperative simulation facilitated the understanding of surgery. ConclusionsThe method of virtual model of intravascular interventional devices was reliable.The preoperative simulation results could be used to guide practical clinical operation with relatively high degree of similarity,and could play a role in promoting researches on interventional virtual operations.
