Objective To investigate the clinical efficacy and safety of recombinant tissue type plasminogen activator(rr-PA) and urokinase(UK) in the treatment of acute myocardial infarction (AMI).Methods According to the digital table,128 patients with AMI were randomly divided into two groups,64 cases in each group.The control group adopted UK intravenous thrombolytic therapy,while the observation group adopted rr-PA intravenous thrombolytic therapy.The recanalization condition at different time after thrombolytic therapy,the incidence rate of cardiovascular events and death rate were compared between the two groups.Results The recanalization rate at 30min,60min and 120min after thrombolysis of the observation group were 29.69 ％,59.38 ％ and 93.75 ％,respectively,which were significantly higher than 14.06％,35.94％ and 68.75％ of the control group(x2 =6.34,7.01,7.45,all P ＜ 0.05) ;The incidence rate of cardiovascular events and mortality rate of the observation group after thrombolytic therapy were 17.19％ and 4.64％,respectively,which were significantly lower than 40.63％ and 12.50％ of the control group (x2 =7.83,7.62,all P ＜ 0.05).Conclusion Recombinant tissue type plasminogen activator intravenous thrombolytic therapy has significant effect in the treatment of acute myocardial infarction after thrombolysis,which can reduce the incidence of cardiovascular events and mortality,with good clinical application value.

Objective To investigate the related factors of phlebitis caused by PICC and support effective preventive nursing measures. Methods 163 patients diagnosed as malignant tumor who first used peripherally inserted central catheters (PICC) were recruited. Patients were observed for 3 months. According to the diagnostic criterion of infection, 34 patients with phlebitis were divided into the phlebitis group and others were divided into the control group. All patients were investigated for general information survey :sex, age, tumor type, allergic history,location of inserted vein, one-time success rate,activity after catheter, elbow bending,phlebitis occurred time, grade and type. Laboratory markers:WBC,neutrophils,immune parameters, fasting plasma glucose. Trait anxiety inventory (T-AI)was used for assessment of emotional state. Case-control study between groups was carried out. Results The results of univariate analysis showed that location of inserted vein,times of inserting vein,activity of inserted limb,elbow bending,blood sugar level and emotion were associated with phlebitis. Sex, age, tumor type, allergic history, immune function,WBC,neutrophils were not involved with phlebitis. The results of multivariate logistic regression analysis showed that PICC through basilica vein was the protective factor. Multiple insertions, more activity of inserted limb,durative anxious emotion were the risk factors of phlebitis. Conclusions Different location of vein,times of inserting vein,activity of inserted limb,elbow bending,high blood glucose level and persistent anxious emotion are the risk factors of phlebitis. Taking effective preventive measures before,during, and after PICC can reduce the incidence of phlebitis.

Objective To investigate the necessity of clamping the indwelling catheters before removal in patients with cervical cancer postoperatively. Methods A total of 198 cases of patients with cervical cancer after radical hysterectomy were divided into the study group (70 cases) and the control group (128 cases) randomly according to operation time. In the study group the catheters were clamped intermittently by patients 2 days before removal, while in the control group the catheters were removed without clamping. The rate of recatheterization, urinary tract infection, as well as the residual urinary volume were compared between groups. Results There were no significant differences in the rate of urinary tract infection and recatheterization between the two groups (P>0.05). The residual urinary volume was significantly higher in the study group than that in the control group ( χ2=10.293, P=0.016). Conclusions There may be no positive effect of training the bladder function by clamping the indwelling catheters before its removal in patients after radical hysterectomy, besides, it can not change the risk of recatheterization and can increase the residual urine in the bladder 24 hours after removal of the catheter.

Objective To discuss the influence of team-based learning (TBL) on autonomous learning ability of undergraduate nursing students. Methods 160 undergraduate nursing students of Grade 2010 were randomly divided into experimental group and control group with 80 students in each group. Students in the experimental group were taught with TBL while students in the control group were taught with lecture-based learning (LBL). The score of autonomous learning ability was measured by scale of self-directed learning ability for nurses. Results Scores of autonomous learning ability in experimental group (120.33 ±16.09) was higher than that of control group (110.87 ±11.89) (P=0.000) and also higher than that of experimental group (100.35±11.15) before the implementation of TBL (P=0.000). The differences were statistically significant. Conclusion Team-based learning (TBL) can be helpful in improving the autonomous learning ability of undergraduate nursing students.

Purpose To investigate the clinicopathologic features of calcifying aponeurotic fibroma (CAF). Methods The clinical and pathologic profiles of 6 cases of CAF were retrospectively analyzed. Results CAF appeared a firm, painless and slowly growing mass with a predilection for the distal portions of the extremities in young children and adolescents. Microscopically, the tumor consis-ted mainly of benign appearing spindle cells, chondroid cells and calcific debris. Immunohistochemically, the tumor cells were positive for vimentin, HHF-35, S-100, Calponin and CD68. Conclusion CAF is a rare, locally aggressive fibroblastic lesion. It can make an accurate diagnosis by integrating the clinical location with histopathological features. Repeated minor trauma to the extremities and some embryologic cell nests maybe its pathogenesis.

Objective: To investigate hard tissue changes produced by maxillary protraction in patients with skeletal Class III malocclusion at different bone age,and to determine the relationship between the effect of maxillary protraction and bone age.Methods:75 subjects of skeletal Class III malocclusion with retruded maxilla were treated by maxillary protraction and rapid maxillary expansion for 6 months.Cephalometric radiographs were taken before and after treatment.The bone age of individual patients was assessed using cephalometric radiographs at the initiation of treatment on the basis of cervical vertebrace maturation indicators(CVMI).Patients were divided into three groups:Prepubertal growth peak group (CVMI Ⅰ-Ⅱ,8.2-11.3 years old), pubertal growth peak group (CVMI Ⅲ,10.2-12.3 yeasr old), and postpubertal growth peak group (CVMI Ⅳ-Ⅵ,11.5-14.5 years old).Results:(1)There was no difference in the maxillary advancement after maxillary protraction between the prepubertal growth peak and the pubertal growth peak groups;(2) in the postpubertal growth peak group, there was a decrease in maxillary skeletal advancement, whereas the dentoalveolar advancement was increased; (3) the posteroinferior rotation of mandible, the increase of lower facial height, and the eruption of maxillary molars showed no correlation with bone age.Conclusion:The importance of performing a biologic evaluation of bone age in the diagnosis and treatment planning of skeletal Class III malocclusions in individual patients must be emphasized.
