Objective To study the technique and clinical significance of percutaneous thoracic biopsy using CT fluroscopic guidance.Methods 76 cases including 68 lung nodules, 5 mediastinal masses and 3 pleural lesions were undergone this procedure. Results The successful rate of the procedure was 100% for all the 76 cases. The diagnostic accuracies were 97.9% for malignant lesions (47/48), 92.3% for benign lesions (26/28), with a total accuracy of 96.1%. The complication of pneumothorax was presented in 24 cases of the total members. Conclusions ① The technique of CT fluoroscopy prosseses the virtue of x-ray fluoroscopy and CT. ② Because of the diagnostic high accuracy for malignant and benign lesions, percutaneous biopsy under CT fluoroscopic guidance have important clinical significance for diagnosis of thoracic lesions.

Objective To assess the value of CT in diagnosis and clinical treatment of the traumatic rupture of spleen.Methods There were 35 cases with traumatic repture of spleen,32 cases were comfirmed by operation.Plain CT scans in all cases and contrast-enhanced scans in 4 cases were performed.Results 19 cases were subcapsular hematoma,8 cases were spleen hematoma,6 cases were rended in one place of spleen,2 cases were rended in many places of spleen.Conclusion The difinite diagnosis and classification of traumatic rupture of spleen can be made by CT.The rupture of the organs around the spleen also can be found by CT,that can provide reliable evidence for clinical treatment.

Objective To investigate the effects of four interior-warming drugs( galangal,cinnamon,evodia rutaecarpa,and dried ginger)on the tension of ileum smooth muscle and Ca2+-ATPase on the cell membrane in rabbits. Methods The effects of galangal,cinnamon,evodia rutaecarpa,and dried ginger were examined on normal ileum smooth muscle,in vitro intestinal muscle contraction caused by acetylcholine(ACh),barium chloride(BaCl2 )and histamine(His), and ACh-induced calcium release by using BL-420E+ biological signal collection and processing system.The average tension was measured within 1 min before delivery and within 3 minutes after the treatment,and the inhibition rate was calculated according to the average tension value.The effects of sera containing galangal,cinnamon,evodia rutaecarpa,and dried ginger on Ca2+-ATPase activity on the cell membrane of the intestinal smooth muscle were examined by phosphorus method. Results Galangal,cinnamon,evodia rutaecarpa,and dried ginger at high concentrations could restrain in vitro intestinal contraction in normal circumstances(P<0.05 or P<0.01).Significant inhibitory effects on intestinal contraction caused by ACh,His and BaCl2 were found in low,medium and high concentration groups(P<0.01).There was a dose-effectiveness relationship between the inhibition rate and final drug concentrations.The ACh-induced intracellular and extracellular calcium dependent contraction were significantly inhibited by the four interior-warming drugs( P < 0. 05 or P < 0. 01). The Ca2+-ATPase activities were( 0. 384 ± 0.070),(0.302±0.016),(0.307±0.016),(0.296±0.016),(0.313±0.003)U·mg-1 ,respectively,in intestinal smooth muscle in normal control group and high concentration groups of galangal,cinnamon,evodia rutaecarpa,and dried ginger(P<0.01). Conclusion Interior-warming drugs may relax intestinal smooth muscle by reducing the intracellular calcium release and the extracellular calcium inflow via receptor-controlled calcium channels,and inhibiting the Ca2+-ATPase activity in smooth muscle.

Objective:To investigate the status quo of readiness for hospital discharge of patients with coronary heart disease after percutaneous coronary intervention(PCI)and analyze the main factors affecting readiness for hospital discharge.Methods:With a cross-sectional survey method, a total of 343 patients with coronary heart disease after PCI in the Affiliated Hospital of Southwest Medical University were selected by convenience sampling method and investigated by General Information Questionnaire, Readiness for Hospital Discharge Scale, Care Transitions Measure and Self-Efficacy Questionnaire of coronary heart disease. Multiple linear regression analysis was used to analyze the influence factors.Results:The total score of Readiness for Hospital Discharge Scale of patients with coronary heart disease after PCI was 94.33±8.67. The score of quality of care transitions was 47.59±5.51 and that of self-efficacy was 39.19±8.08. Multiple linear regression analysis showed that five variables including self-efficacy, length of hospital stay, marital status, residence and family history of coronary heart disease entered into the regression equation ( P<0.01), which could explain 50.0% of the variations of readiness for hospital discharge. Conclusions:The readiness for hospital discharge of patients with coronary heart disease after PCI is at the middle level. The main influencing factors are self-efficacy, length of hospital stay, marital status,residence and family history of coronary heart disease. Nurses should attach importance to the self-efficacy of patients and pay attention to high-risk groups. By improving patients′ self-efficacy and giving targeted guidance ahead, in order to improve patients′ perception of readiness for hospital discharge.
