After the concept of risk of literature acquisition was described, its universal, objective, losing, controllable and social featureswere pointed out , followed by an analysis of the factors and related conditions for its occurrence , its consequences and possible losses, with measures proposed for its control.

Objective To explore the therapeutic efficacy for fractures around the knee with concurrent vascular and nerve injury.Methods The clinical data of 75 patients with fractures around the knee with concurrent vascular and nerve injury treated were retrospectively analyzed.And fracture reduction,vascular repair and nerve repair were given depending on degree of injure.Therapeutic efficacy of the treatments was recorded.Results 5 cases were amputation,while the others were alive,the rate of efficacy was 93.06％.27 of the 31 cases of contusion nerve were returned to normal,4 were returned to part of the sensory-motor,11 of 13 cases of completely torn nerve were recovering well,and 2 of which were 2 degree,and the rate of efficacy was 86.36％.Conclusion The appropriate measures and early treatment should be given,by which prognosis of limb could be improved comspicuously,and the order of vascular repair and fractures fixation is influential on surgery success.

The medical teaching assistant terrace has been established and finished in the digital libraries.It has increased library function,satisfied medical teaching innovating demand and advanced library value and position.It has also provided the chance and established the direction of the development for library and its workers.

It is required by objective reality to discuss the teaching conception and mode of evidence-based medicine,based on its nature and from the fundamental differences between it and traditional medicine.

Objective To understand the prevalence of erectile dysfunction (ED) in elderly male and to provide the basis for clinical diagnosis and treatment of ED. Methods The questionnaire about sexual history was used, and related past history, medication and life-style were reviewed. Results Total prevalence of ED was 89.7% in the 272 elderly male persons. The prevalence of 60-years group, 70-years group and 80-88 years group was 75.9%, 78.6% and 100%, respectively. Among ED patients, 95.1% of them suffered from hypertension. Conclusions Prevalence of ED in elderly male persons is associated with the ageing and the hypertension.

Objective To observe the clinical effect of mifepristone combined with intramuscular injection of methotrexate in the treatment of cesarean scar pregnancy.Methods Fifty-six patients with uterine scar pregnancy after cesarean section were divided into observation group and control group by random number method.The control group was intramuscularly injected methotrexate,the observation group was given methotrexate combined with mifepristone therapy.The therapeutic effect,blood β human chorionic gonadotropin(β-HCG) decreased to normal time,vaginal bleeding time,mass size were observed.Results After treatment,the serum β-HCG decreased to normal time[(15.96±3.71)d] and vaginal bleeding time[(5.12±2.08)d] of the observation group were significantly shorter than those of the control group [(25.42±4.02)d,(7.39±3.37)d],the mass size of the observation group [(1.88±0.15)cm] was also significantly smaller than (2.14±0.33) cm of the control group,and there were significant differences between the two groups(t=4.3142,3.0331,3.7954,all P＜0.05).Conclusion Mifepristone combined with intramuscular injection of methotrexate has significant effect on uterine scar pregnancy after cesarean section.

Objective To discuss the influence of Doula delivery and non -Doula delivery on cesarean section(CS)morbidity. Methods796 cases with Doula delivery and 800 cases with non-Doula delivery were compared in CS morbidity, CS causes, dystocia morbidity in vaginal delivery and neonatal distress. ResultsThe main causes of CS in both groups were fetal distress, fetal malposition and cephalopelvic disproportion and uterine inertia (problems of"power"), The CS morbidity in Doula delivery group(24.37%) was significantly lower than that in non-Doula group(38.25%) (P<0.01). In Doula delivery, CS due to uterine inertia was significantly less than that in non-Doula delivery (P<0.05). However, CS rate due to fetal distress was higher in the former group (P<0.05). In the vaginal delivery cases of the two groups, dystocia morbidity in Doula delivery group(6.00%) was statistically lower than that in non-Doula delivery group(9.72%) (P<0.05). The rates of neonatal distress in the two groups were not significantly different (P>0.05). ConclusionDoula delivery can decrease the CS morbidity without increasing the rate of neonatal distress. Therefore, Doula delivery is worth administering in clinical practice.

Objective To explore the value of peak systolic displacement of tricuspid annulus(TAD)in evaluation of right ventricular systolic function by speckle tracking imaging(STI).Methods The study population consisted of 24 healthy subjects(control group)and 16 patients with congestive heart failure(CHF).The apical four-chamber view was obtained and imput to Qlab 6.0 workstation. The TAD at the right ventricular free wall (TADla)and the midpoint of tricuspid annulus(TADmid)were measured and calculated automatically.Right ventricular ejection fraction(RVEF)was measured by real-time three-dimensional echocardiography.The correlation of displacement parameters with RVEF was analyzed.Results In all 40 subjects, the mean value of TADla was(19.3±5.9)mm with s range from 7.8 to 28.4 mm while the mean value of TADmid was(15.3±4.6)mm with a ranging from 7.2 to 22.2 mm.The parameters in CHF group were significantly lower than those of the control group(P<0.01).TADla and TADmid showed an excellent correlation with RVEF(r=0.87 and 0.91 respectively,P<0.01).The cut-off value of TADla for RVEF<45%was 17.2 mm with a sensitivity of 89%and a specificity of 93% while the cut-off value of TADmid for RVEF<45% was 13.1 mm with a sensitivity of 96%and a specificity of 1 00%.Conclusions TAD by STI showed an excellent correlation with RVEF, and it may be a new promising method for routine evaluation of right ventricular systolic function.
