Objective To evaluate the technique and clinical effect of arthroscopic treatment of anterior cruciate ligament tibial eminence avulsion fracture with suture bridge fixation technique. Methods From May 2013 to July 2015, 18 patients with anterior cruciate ligament tibial eminence avulsion fracture were treated with arthroscopic re﹣duction and fixation by suture bridge technique. There were 12 males and 6 females with an average age of 29.8 years old (range, 9~45 years). The right knees were involved in 10 cases and left knees in 8 cases. The injury caus﹣es included traffic accident injury in 10 cases, sports injury in 5 cases and other reasons in 3 cases. 2 patients had old fracture, the others had fresh fracture. The results of Lachman and anterior drawer test were both positive. The International Knee Documentation Committee (IKDC) subject score was (53.8 ± 4.2). Based on Meyers-Mckeaver classification, there were 5 cases in typeⅡ, 10 cases in type Ⅲ and 3 cases in type Ⅳ. Results The operation time was 50~80 minutes (mean, 60.5 minutes), X-ray showed satisfactory fracture reduction after surgery. Primary healing of incision were obtained with no infection, all 18 patients were followed up for 6 ~ 31 months (mean, 18.6 months). The results of Lachman and anterior drawer test were both negative in 17 cases, the result was negative for anterior drawer test and was weakly positive for Lachamn test in 1 case. The IKDC subject score were significantly improved to (95.2 ± 3.8) at last follow-up (P< 0.05). Conclusion It could achieve early restoration of knee joint function to treat the anterior cruciate ligament tibial eminence avulsion fracture with suture bridge fixation technique because of satisfactory reduction, reliable fixation, minor trauma, and quick recovery.

Objective: To investigate the effect of puncture-related pain on the quality of life in patients undergoing maintenance hemodialysis through internal arteriovenous if stula. Methods: A total of 180 hemodialysis patients with the arteriovenous ifstula were surveyed by the kidney disease quality of life short form(KDQOL-SF1.3), demographic data questionnaire, visual analogue scale and pain self-effcacy questionnaire. Results: The median score of puncture-related pain was 5 and the score of pain self-efficacy was (31.42±14.59). The quality of life in the patients undergoing maintenance hemodialysis is poor. KDQOL-SF1.3 was (69.45±24.19), SF-36 was (49.82±19.17) and ESRD-targeted was (55.46±18.37). Multivariate analysis demonstrated that the quality of life was positively correlated with the patient gender (β=0.152,P<0.05, OR=1.638, 95% CI 1.241–1.954), working position (β=0.307,P<0.05, OR=2.069, 95% CI 1.206–-3.148), using time of arteriovenous ifstula (β=?0.815, P<0.05, OR=0.223, 95% CI 0.095–0.741), the score of pain (β=-0.017,P<0.05, OR=1.004, 95% CI 0.886–1.431) and pain self-effcacy (β=-0.409,P<0.05, OR=0.803, 95% CI 0.710–0.984). hTere existed negative correlation between the quality of life score and the puncture-related pain score in these patients (r=-0.472,-0.465,-0.381,P<0.01), positive correlation between the quality of life score and the score of pain self-efficacy (r=0.647, 0.203, 0.518,P<0.05), and negative correlation between the puncture-related pain score and the score of pain self-effcacy(r=-0.745,P<0.01). Conclusion: Puncture-related pain is a crucial inlfuential factor on the quality of life in the patients undergoing maintenance hemodialysis through internal arteriovenous ifstula.

AIM: To explore the anti-tumor effect and the mechanism of dihydroarteannuin in C57BL/6J mice with lewis lung cancer. METHODS: Fifty C57BL/6J mice subcutaneously planted with 3LL lung cancer cells (2?106) were randomly divided into 5 groups: blank control group, same volume of normal saline group, positive control DDP group, low, middle and high dose dihydroarteannuin groups. Changes of body weight and inhibitory rate of tumor in each group were observed. The cell cycle and apoptosis rates were analyzed by flow cytometry. RESULTS: The body weights were decreased in middle and high dose group compared with NS group and the inhibitory rate of tumor were 53.50% and 59.24% respectively. FCM assay indicated that Dihydroarteannuin could induce apoptosis of lung cancer cell. At the same time, the number of G0/G1 and G2/M phase cells was decreased. Most of the cells were arrested in S1 phase. CONCLUSION: Dihydroarteannuin has obviously effect on anti-tumor in C57BL/6J mice with lung cancer. Its possible mechanism might be involved in inducing cancer cell apoptosis.
