ObjectiveTo explore the feasibility and safety of the spleen-preserving surgery in the treatment of traumatic rupture.Methods47 patients with traumatic rupture were treated with spleen-preserving surgery:the biological glue which local physical bleeding had 7 cases,suture repair had 13 cases,splenic artery ligation had 10 cases,splenic artery ligation and splenic repair had 9 cases,partial splenectomy had 8 cases.Results47 patients had four cases of infection,and cured after dressing,1 case had postoperative bleeding symptoms and used splenectomy surgery.46 patients with spleen-preserving operation is successful,the average length of stay was 15 days,there is no deaths.After 6 months,all patients used abdominal B-utrasoundor CT scans to confirm the survival of spleen is good and indicator of the examination is normal.Follow-up of these patients had no dangerous infections and complications.ConclusionSpleen-preserving surgery in the treatment of traumatic rupture was safe,feasible,could retain the greatest degree of function,and could be used in clinical practice.

Objective The aim of the study was to determine the diagnostic value of color Doppler ultrasound in the assessment of the breast mass.Methods The results of ultrasonograph of the breast mass were retrospectively observed in 79 operation and pathological proven breast mass parients,in which 47 patients had proven malignant breast mass and 32 patients had proven benign malignant breast mass.Results Color Doppler ultrasound had a sensitivity of 100%for diagnosing breast mass,accuracy of 93.7%(30/32)and 91.4%(43/47)for diagnosing malignant and benign mass.Conclusion Color Doppler ultrasound has high diagnostie value in distinguishing malignant from benign mass.

Objective:To assess the value and indication of endoscopic intervention for acute severe pancreatitis(ASP).Methods:A series of consecutive patients with (26 cases) was treated mainly with endoscopic naso-biliary drainage(ENBD),sphincterotomy (EST) as well as drugs,Abdominal pain duration:raised serum amylase period surgical intervention rate mortality rate and average be in hospital number of days.Results:Abdominal pain duration was (2.5±1.5) days in treatment group with endoscopic and (5.1±2.4) days in control group respectively (P<0.05),raised serum amylase period was (2.8±1.3) days in treatment group with endoscopic and (4.8±1.8) days period in control group respectively(P<0.05),mortality rate was 3.85% (1/26) in treatment group with endoscopic while 16.67% (5/30),P<0.05,average be in hospital number of days was (17.2±5.2) days in treatment group with endoscopic and (26.2±18.2) days in control group respectively.Conclusion:ENBD+EST the intraductal pressure can be lowered and the cause of occlusion be relieved with therapeutic effect.It is considered that endoscopic intervention is a practic of choice for selected.

OBJECTIVE： To investigate the possible role of the alteration of mitochondrial transmembrane potentials(Δ Ψ m) in arsenic trioxide(As2O3)-induced apoptosis of human gastric adenocarcinoma cells(SGC7901).METHODS： Cell apoptosis was assessed through morphology， cell viability， the percentage of sub-G1 cells and phosphatidylserine(PS) externalization.the Δ Ψ m was detected on flow cytometry through double staining of Rhodamine 123 (Rh123) and propidium iodide(PI).RESULTS： The As2O3-induced apoptosis was associated closely with the disruption of the Δ Ψ m.CONCLUSION： The disruption of the Δ Ψ m is one of the mechanisms of As2O3-induced apoptosis.

Objective To study the value of imaging characters in diagnosing mediastinal tumors.Methods X-ray and CT findings of pathologically proved mediastinal tumors in 58 cases were analysed,the findings enabling qualitative diagnosis were recommended. Results There were 40 cases of anterior mediastinal tumors including intrathoracic thyroid tumors [n=32,5 tyroid carcinomas and 1 thyroid cyst ,thymomas (n=3) and teratomas (n=5, 3 cases ruptured)]. All the other 18 cases in posterior mediastinum were neurogenic tumors.Conclusion Based on the combination of the mediastinal compartment knowledge, X-ray and CT findings of the tumors and the clinical information, the qualitative diagnosis of mediastinal tumors will be characterized correctly.

Objective To study the expression of Livin and its relationship with Caspase-3, FHIT in skin squamous cell carcinoma. Methods lmmunohistochemical assay was used to detect the expression of Livin, Caspase-3 and FHIT in 48 cases of sSCC, 20 cases of chronic ulcer and 12 cases of normal skin tissues. Results The rate of positive expression of Livin in SCC tissues was significantly higher than that in the chronic ulcer tissues and normal skin tissues (P <0.01). The rate of positive expression of Caspase-3 and FHIT in SCC tissues was significantly lower than that in the chronic ulcer tissues and normal skin tissues (P < 0.01).The expression of Livin and Caspase-3 had relationship with the lymphatic metastasis and histologic differentiation of SCC(P <0.05). The expression of Livin and Caspase-3 had not relationship with age, sex, the sizes of SCC (P >0.05). There was negative significant correlation between the expression of Livin and the expression of Caspase-3, FHIT. Conclusion There may be relationship between the abnormal expression of Livin and Caspase-3, FHIT and the occurrence, progression of skin squamous cell carcinomas. They may become a new method for preservation and treatment skin of squamous cell carcinomas.

Objective:To investigate the influences of laparoscopic surgery on Th1/Th2 balance in patients with uterine myomas.Methods:In a prospective study,the number of the Th subsets,Th1/Th2 ratio,the serum level of IL-18 and IL-10 in 20 patients submitted to laparoscopic operation and 20 patients undergoing conventional open operation were evaluated preoperatively as well as 2,24,48 h postoperatively.Results:The level of Th1 cell,IL-18,and the Th1/Th2 ratio decreased significantly (laparoscopic group: P
