Clinical observation on the prevention of postoperative deep vein thrombosis with 3 diffrent measures / 重庆医科大学学报

Objective: To eplore the effective measure to prevent postopelative deep vein thrombosis (DVT).Methods:510 cases of hospitalzed surgical patients from January 2005 to December 2007 were divied into observation group(without any preventive measure) and control group(including physiotheragy group,elastic socks with gradient pressure group and intermittent pressure device group).To observe the patients changes in 10 days after operation.Results:There were 6 cases of DVT in 125 cases of observation group(with the occurrence rate of 4.8%).In control group,there was I case of DVT in 125 cases of physiotherapy group(with the occurrence rate of 0.8%) and no cases of DVT in the other two observation groups.Conclusion:The elastic soks with gradient pressure and the intermittent pressure device can effectively prevent the occurrence of postoperative DVT.

Formulation of College Clinical Learning Environment Scale for Nursing and Test of Its Reliability / 中华医学教育探索杂志

Objective:To draw up a scale of clinical learning environment for nursing to elevate nursing practicing.Methods:Based on the knowledge and studies of the clinical learning environment and focus group discussion with students,reliability of the scale was measured by questionnaire,using reliability and test-retest correlation to evaluate the reliability of the scale.Result:Both the reliability and the test-retest correlation coefficient were more than 0.7(P

Nursing care of patients with deep vein thrombus of lower limb treated with inferior vena cava filter implantation / 重庆医科大学学报

Objective:To investigate the nursing for patients with deep venous thrombosis before and after placing inferior vena cava filter.Methods:A retrospective analysis of the 75 patients who have been placed inferior vena cava filter.Results: Serious complications,for example,overly worried,anxiety,fear,the puncture point hemorrhage,infection,thrombosis falling off, death,and so on,have not occurred during hospitalization of the 75 patients.Conclusion:As long as targeted prevention and nursing,the short term of filtering can be completely prevented.

Alterations of calcium channel gene expression and function in rat ventricular myocytes infected by virus / 中国病理生理杂志

AIM: To investigate the changes of the L-type calcium channel subunit expression and calcium currents (I_~Ca -L) in cultured rat ventricular myocytes infected by coxsackie virus B_3 (CVB_3). METHODS: Primary cultured neonatal rat ventricular myocytes were infected with CVB_3. The changes of L-type calcium channel subunits mRNA in normal and infected myocytes were measured by semi-quantitative reverse transcription-polymerase chain reaction. I_~Ca -L was recorded in two groups respectively using whole cell patch-clamp techniques. RESULTS: The expression of ?_1 and ? subunits of L-type calcium channel mRNA increased in the infected group compared with the normal one (4.00?0.07 vs 2.21?0.41, P0.05). The average current density of I_~Ca -L significantly increased by CVB_3 infection [(-8.66?0.99) pA/pF vs (-6.97?1.75) pA/pF, P
