To compare the clinical results of arthroscopic single and double-bundle ACLs reconstructions. From January 2009 to May 2010,45 patients with anterior cruciate ligament tear were divided into two groups. In the first group,the anterior cruciate ligament were anatomical reconstructed with double-bundle semitendinous tendon, and in the second group the anterior cruciate ligaments were anatomical reconstrucated with single bundle semitendinous tendon. There were 22 patients (15 males and 7 females) in double-bundle group, with an average age of (27.04 +/- 3.68) years; 18 patients (13 males and 5 females) in single bundle group, with an average age of (28.16 +/- 4.76) years. Therapeutic effects between two groups were compared according to the IKDC, Lysholm scoring standards and Lachman test, knee pivot shift test, KT-1000. Twenty-two patients in double-bundle group and 18 patients in single-bundle group were followed-up, and the mean duration was 12 months. The IKDC score of patients in single-bundle group improved from preoperative 41.40 +/- 6.30 to postoperatively 95.70 +/- 3.10, Lysholm score increased from preoperative 47.20 +/- 6.30 to postoperative 94.20 +/- 2.40. And the IKDC score of patients in double-bundle group improved from preoperative 40.90 +/- 6.10 to postoperative 96.10 +/-3.40, Lysholm score increased from preoperative 48.10 +/- 6.50 to postoperative 95.10 +/- 2.49. There was no statistically significant difference between the two groups. The Lachman test was positive in 2 patients (1 patient in double-bundle group and 1 patient in single-bundle group); and pivot shift test was positive in 2 patients (1 patient in double-bundle group and 1 patient in single-bundle group). KT-1000 of patients in double-bundle group was (1.5 +/- 1.2) mm, and (1.9 +/- 1.5) mm in single-bundle group, there were no statistically significant differences between the two groups. Arthroscopic single-bundle reconstruction and double-bundle anterior cruciate ligament reconstruction have no significant differences in clinical effects. Source

To explore the characteristics, diagnosis and treatment on traumatic dislocation. From April 2000 to August 2010, 12 patients with acute traumatic dislocation of superior tibiofibular joint were treated including 10 males and 2 females with an average age of 30.6 years old ranging from 18 to 60 years. According to Ogden classification, 8 cases were the anterolateral dislocation, 2 were posterior-medial dislocation, and 2 were upward dislocation. All patients had swelling in lateral-inferior of knee, fibular head prominent, fibular head pain, floating feeling in head of fibula. One case was treated by conservative treatment, and the remaining 11 cases by surgical treatment. All patients were followed-up for 10 months to 3 years (means 18 months). Evaluation by Lysholm scoring,the total scores were 95.08 +/- 2.02, involving limbing 4.92 +/- 0.28, support 4.92 +/- 0.28, interlocking 15.00 +/- 0.00, instability 24.58 +/- 0.79, pain 22.50 +/- 1.24, swell 8.50 +/- 0.90, climbing stairs 9.75 +/- 0.62, squatting 4.92 +/- 0.28; 11 cases achieved excellent results and 1 good. Nerve functional recovered. X-ray was no longer dislocation. The diagnosis of traumatic dislocation is easy misseddiagnosis, surgery is the main treatment method, the prognosis is good. Source

A novel series of quinolone derivatives (6a-n) were designed and synthesized, and their biological activities were evaluated as potential antitumor topoisomerase I (Top I) inhibitors. Among these compounds, 6j exhibited the most potent antitumor activities against multiple cancer cell lines. Docking simulation was performed to insert compound 6j into the crystal structure of DNA-Top I to determine the probable binding model. © 2013 The Pharmaceutical Society of Japan. Source

The aim of this study was to detect novel variants of the Stenotrophomonas maltophilia Smqnr gene family and analyse the prevalence of Smqnr genes in clinical isolates of S. maltophilia in China. In total, 442 clinical isolates of S. maltophilia were collected from nine hospitals in four provinces in China. Antimicrobial susceptibility testing against six commonly used antibiotics was performed on these isolates. The sequences of the Smqnr genes amplified by PCR were aligned with those of known Smqnr genes in GenBank and an Smqnr database. The resistance rate against co-trimoxazole was highest at 48.6 %, followed by resistance rates against ceftazidime, chloramphenicol, ticarcillin/clavulanate and tigecycline at 28.7, 21.3, 19.0 and 16.1 %, respectively. The highest susceptibility was shown to levofloxacin, with a resistance rate of just 6.1 %. Smqnr genes were detected in 114 isolates, and comprised 11 previously identified genes and 20 new variants, bringing the total number of known Smqnr genes to 47. The 20 novel Smqnr genes were designated Smqnr28-47 and the encoded proteins showed only 1-12 amino acid differences among each other. The most common Smqnr genes in China were Smqnr8 and its variant Smqnr35 with prevalences of 17.5% (20/114) and 13.2% (15/114), respectively. Both the known and the novel Smqnr genes were discovered in both quinolone non-sensitive and sensitive isolates with similar frequency, suggesting that the Smqnr gene makes little contribution to quinolone resistance in this organism. © 2012 SGM.

Objective: To evaluate the diagnosis and treatment of malignant nonurothelial tumor of urinary bladder. Methods: Ten cases of malignant nonurothelial tumor of urinary bladder treated from 2000-2008 were reviewed. Six of 10 patients underwent radical cystectomy, 1 partial cystectomy,2 TURBt, I only biopsy. Results: Malignant nonurothelial tumor of urinary bladder accounted for 4.5% of the bladder cancer. Ten cases were followed up from two months to five years. The mean survival time was 17.4 months. Conclusion: Malignant nonurothelial tumor of urinary bladder is rare, with bad prognosis. Radical cystectomy should be regarded as the first choice for these patients, and comprehesive therapy may improve the efficacy. Source
