Objective To evaluate more than 5-year follow-up outcome of avulsion fracture of the anterior cruciate ligament from the tibial insertion site in skeletally immature patients treated with modified arthroscopic internal fixation with cannulated screw and washer. Methods Thirty-nine patients with open physis were treated by modified arthroscopic internal fixation with cannulated screw and washer from March 2000 to November 2003. Regular X-ray plain films at AP and lateral views were conducted to detect the healing of avulsed fragments. Follow-up period of 31 patients was more than 5 years. Functional outcome before and after surgery was evaluated using the Lysholm Knee Score and the Tegner Activity Score. Angular deformity, or leg length discrepancy was assessed by clinical examination and anteroposterior-lateral radiographs of the knee. Instrumented knee laxity was performed using the KT-2000 arthrometer. Results Arthroscopic removal of implants was performed between 3 and 6 months postoperatively, when all fractures were revealed to have healed on X-ray films. No growth disturbance, angular deformation or knee instability was found in 31 patients during more than 5-year follow-up. The Lysholm score was improved from (19.2?14.8) (range 12-48) preoperatively to (98.5?3.1) (range 97-100) postoperatively, with significant statistical difference by the student-t test (t=18.395, P=0.000); The Tegner score was improved from (4.1?1.1) (range 3-5) preoperatively to (8.5?0.8) (range 7-9) postoperatively, with significant statistical difference by the student-t test (t=4.13, P=0.008). Physical examination showed Lachman test (+) in 14 of 31 patients. Instrumented knee laxity (KT-2000) showed manual-maximum side-to-side difference greater than 2 mm (range 2.1-3.8 mm) in 14 of 31 patients. Conclusion Modified arthroscopic internal fixation of avulsion fracture of the anterior cruciate ligament from the tibial insertion site with cannulated screw and washer in skeletally immature patients is a simple, safe, and effective ARIF procedure without growth disturbance.

OBJECTIVE:To investigate the utilization of opioid analgesic drugs in a hospital,so as to provide reference for ra-tional drug use in clinic. METHODS:The utilization of opioid analgesic drugs in the hospital during 2014-2016 was analyzed and compared retrospectively in terms of consumption sum,DDDs,DDC,B/A,etc. RESULTS:Annual consumption sum of opioid an-algesic drugs in the hospital increased slightly in 2015,but decreased significantly in 2016. Fentany transdermal patches(8.4 mg), Oxycodone and acetaminophen tablets and Remifentanil hydrochloride for injection always took up the first 3 places in the list of DDDs. DDDs of Fentanyl citrate injection(0.1 mg)and Morphine sulfate sustained-release tablets increased year by year;while DDDs of Fentany transdermal patches(4.2 mg)and Fentany transdermal patches(8.4 mg)decreased year by year. DDC of all opi-oid analgesic drugs decreased in 2016,with the cancel of drug price addition at the end of 2016. B/A values of most drugs were close to 1.0;while B/A value of Oxycodone hydrochloride sustained-release tablets(40 mg)was much less than 1.0,and that of Fentany transdermal patches(8.4 mg)and Oxycodone and acetaminophen tablets were significantly more than 1.0 for consecutive 3 years. CONCLUSIONS: The variety and specifications of opioid analgesic drugs in the hospital is comprehensive during 2014-2016. The clinical utilization of opioid analgesic drugs is generally rational,but still needs to be supervised effectively and par-ticularly,so as to improve standard use of opioid andalgesic drugs.

Objective To assess the clinical outcome of varicose veins with incompetent great saphenous vein(GSV) treated with ultrasound guided foam sclerotherapy. Methods Forty limbs with moderate to severe symptomatic varicose veins with incompetent GSV in 38 patients were injected with foam sclerosing agent (Fibro-Vein) under ultrasound guidance. There were 36 patients with unilateral varicose veins and 2 with bilateral varicose veins. No of them suffered from deep vein incompetence or perforating vein incompetence. Second injection was performed one month after the initial injection in 7 limbs. Thirty-eight of 40 limbs were followed up with clinical examination and duplex ultrasound scan 30-47 months (mean 40 months) after the treatment. Results Among 38 limbs with follow-up mild debilitation was found in two limbs(5. 3%). There were no other symptoms or complications. Duplex ultrasound demonstrated four type of results: type I, sclerosed GSV trunk with no detectable venous flow in 32 of 38 limbs (84. 2%) ;type II,patent GSV trunk in 3 limbs (7. 9%) ,two of them had mild reflux in the GSV trunk;type III,sclerosed GSV trunk and mild reflux in the GSV tributaries, 1/38(2. 6%) ; type IV,sclerosed proximal GSV trunk,patent distal GSV communicated with a superficial vein and mild reflux in the veins, 2/38 (5. 3% ). Conclusions Clinical examination and duplex ultrasound scan demonstrated excellent results of varicose veins with incompetent GSV treated with ultrasound guided foam sclerotherapy 40 months after the treatment. Sclerotherapy is less invasive treatment option for varicose veins with incompetent GSV with satisfactory clinical and cosmetic outcome.

Objective To evaluate the clinical value of double-balloon enteroscopy( DBE)in as-sessing the effect of mucosal healing in patients with moderate small bowel Crohn's disease( CD)treated with low-dose azathioprine. Methods CD patients who were naive to any immunomodulators or biological a-gents with lesions mainly located in ileu were screened by multislice CT enterography and anal-route DBE at baseline. Lesions at 150 cm proximal to ileocecal valve were assessed by DBE with Simple Endoscopic Score for CD( SES-CD)after 12 and 24 months of low-dose azathioprine treatment,respectively. Results A total of 36 patients were enrolled and the average tolerated dose of azathioprine was(61. 8 ± 17. 2)mg/day. The total rates of complete,near-complete,partial and no mucosal healing in 36 patients were 19. 4%(7/36), 5. 6%(2/36),27. 8%(10/36),and 47. 2%(17/36)at month 12 and 30. 6%(11/36),25. 0%(9/36), 33. 3%(12/36),and 11. 1%(4/36)at month 24,respectively. The baseline SES-CD score(OR=2. 71, 95%CI:1. 11-6. 63,P=0. 029)and duration of disease(OR=1. 27,95%CI:1. 10-1. 47,P =0. 001) were two relevant factors associated with mucosal healing of small bowel CD. Conclusion DBE has a signif-icant advantage in assessing post-therapy mucosal healing for patients with small bowel CD. The optimal time point for the first follow-up by DBE is at least 12 months after low-dose azathioprine treatment.
