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： 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.

Coblation is a new technology widely used in the otolaryngology in recent years.This article described the principle,indications,methods and advantages which the coblation was used in pharynx and throat diseases in children.It's a safe,effective and minimally invasive way.

Objective To study the biological effects of hirudin on the cell circle of fibroblasts in hypertrophic scar.Methods Fibroblasts were taken from normal skin and hypertrophic scar,and cultured in vitro with various concentrations of hirudin.Then,flow cytometry was used for observing cellcycles,and Western blot for some proteins (p27 and cyclin E) related with cell circle.Results With the increasing of the concentrations of hirudin,fibroblasts on G1 phase increased and on S phase decreased,and the expression of protein p27 increased,but that of protein cyclin E decreased.Conclusion Hirudin can influence the cell circle of fibroblasts derived from normal skin and hypertrophic scar by means of the expression of some proteins related with celI circle.Hirudin causes G1 phase arrest and inhibits the production of fibroblasts.Therefore,it seems that hypertrophic scar could be prevented and treated with hirudin.

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 analyze the recent condition on medication safety of the elderly with chronic diseases in poor areas of Liaoning Province, the structural equation model(SEM) was used to investigate the influencing factors of the medication safety in order to provide the scientific basis for medication safety and the rational use of drugs. Methods The 1 690 elderly with chronic diseases in poor areas of Liaoning Province were selected by the multi-stage random sampling and investigated with the self-designed questionnaire, the database was established on SPSS17.0, the model of structural equation modeling was built by AMOS17.0. Results The four common factors, which were the knowledge,attitude, practice and adherence of medication safety, were extracted by confirmation factor analysis, and the data of the four common factors was fitted, the fitting parameters were: χ2/DF=2.254, GFI=0.913, NFI=0.909, CFI=0.925, AGFI=0.825, RMSEA=0.062, the model fitting was ideal. Conclusions The medication of the elderly with chronic diseases in poor areas of Liaoning Province exists potential security risks, the knowledge, attitude, practice and adherence of medication safety are the important factors which affect the medication safety, the health education about medication safety should be conducted in the elderly with chronic diseases in the poor areas, to develop the safety, effectiveness and economy of medication among the elderly.

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.
