Objective To observe the short-term curative effect and safety of recombinant human erythropoietin(rHu-EPO)on patients with primary brain stem injury. Methods Sixty patients with primary brain stem injury were recruited at Liaocheng People' Hospital from July 2010 to July 2013. All cases were randomly divided into EPO group and control group. The patients in EPO group were injected subcutaneous with rHu-EPO five times at dose of 6 000 U,while patients in the control group were treated with placebo in 2 weeks. All other conventional treatments were the same. NIHSS score and GOS score were evaluated in two weeks and three months respectively. Moreover,blood pressure and hemoglobin were also measured. Results NIHSS score in EPO group was 11. 37 ± 7. 78,significant higher than that of control group after two weeks(19. 41 ± 8. 26,P = 0. 019). GOS score in EPO group was also significant differences in two groups after three months (Z = - 2. 367,P = 0. 009 ). However,no significant difference was observed in the followed-up blood tests. Conclusion Recombinant human erythropoietin could be the exact nerve protective effect,and might be an effective therapy for patients with primary brain stem injury.

ObjectiveTo explore the short-term curative effect and safety of autologous bone marrow mesenchymal stem cells transplantation in patients with primary brain stem injury.MethodsFifty-four cases with primary brain stem injury were hospitalized during Jul.2007 to Jul.2010 at Liaocheng Brain Hospital,Shandong Province.All cases were randomized into transplantation group( n =30)or control group( n =24 ).The transplantation group was treated with autologous bone marrow mesenchymal stem cell transplantation by subarachnoid space injection (n =30).The control group were selected from primary brain stem injury patients without stem cell transplantation who were hospitalized at the same period with patients from the transplantation group.Respectively,National Institutes of Health Stroke Scale (NIHSS) score was employed to evaluate the condition of patients in the two groups one month after treatment,and Glasgow Outcome Scale (GOS) score was used to evaluate curative effects of the two groups at sixth months after treatment.Meanwhile,some other parameters were observed,including blood routine,clotting mechanisms,biochemicalitemsand tumor markers.ResultsThere was significant difference between the transplantation group and the control group in N IHSS score at one month after treatment [ ( 10.86 ± 7.48) vs.( 18.26 ± 8.74),t =2.681,P ＜ 0.05 ].GOS score was significantly different( Z =2.306,P ＜ 0.05 ) between the transplantation group and the control group at sixth month after transplantation.There was no significant difference between the two groups in the blood examination results during the followed-up period.Conclusion Autologous bone marrow mesenchymal stem cells transplantation is confirmed to be an effective and safe therapy in patients with primary brain stem injury in the short-term.Further evaluation still needs for its long-term efficacy on primary brain stem injury

BACKGROUND:Anterior cruciate ligament avulsion fracture at tibial insertion is a special type of intra-articular fracture,which is mostly seen in sports injuries.At present,there are relatively few anatomical studies on this disease,but a large number of studies focus on the injury of the anterior cruciate ligament.It is generally believed that the increase in the posterior slope of the tibial plateau,the decrease of the depth of the medial tibial plateau,and the decrease in the width index of the femoral intercondylar notch are the risk factors for the injury of the anterior cruciate ligament.It is unclear whether avulsion fractures of the anterior cruciate ligament at the tibial insertion point are also related to it. OBJECTIVE:To investigate the correlation between the avulsion fracture of the anterior cruciate ligament at the tibial insertion and the posterior tibial slope,the medial tibial depth,the notch width index of the femoral intercondylar fossa,and the coronal slope angle of the tibial plateau. METHODS:A retrospective analysis was made on 101 patients who were admitted to the Department of Orthopedics of Affiliated Hospital of Xuzhou Medical University due to anterior knee pain from January 2019 to December 2022.Totally 51 patients with tibial insertion avulsion fracture of anterior cruciate ligament who received arthroscopy treatment were taken as the observation group,and 50 patients with anterior knee pain but no knee joint injury confirmed by physical examination and imaging examination were taken as the control group in the same period.The posterior tibial slope,anatomical parameters such as the medial tibial depth,and the notch width index of the femoral intercondylar fossa,were statistically analyzed for the anatomical risk factors leading to the tibial insertion avulsion fracture of the anterior cruciate ligament. RESULTS AND CONCLUSION:(1)There was no significant difference between the two groups in the comparison of the lateral posterior tibial slope,the posterior slope ratio of the lateral/medial tibial plateau,the notch width index of the femoral intercondylar fossa,and the coronary slope angle of the tibial plateau(P>0.05).The medial posterior tibial slope in the observation group was significantly higher than that in the control group(P<0.05).The medial tibial depth in the observation group was significantly lower than that in the control group(P<0.05).(2)Multifactor logistic regression analysis showed that the medial posterior tibial slope and the medial tibial depth were independent risk factors for tibial insertion avulsion fracture of anterior cruciate ligament(P<0.05).(3)The receiver operating characteristic curve shows that the medial posterior tibial slope and the medial tibial depth had certain predictive values for the tibial insertion avulsion fracture of the anterior cruciate ligament.(4)It is indicated that the increased medial posterior tibial slope and the shallower medial tibial depth are the anatomical risk factors for the avulsion fracture of the tibial insertion of the anterior cruciate ligament.
