Objective To explore the cl inical effectiveness of arthroscopic reconstruction of medial patellofemoral l igament (MPFL) with trabs of medial soft tissues in the treatment of patellar instabil ity of adolescence. Methods From January 2005 to December 2006, 23 cases of patellar instabil ity were treated, including 10 males and 13 females with an average age of 16 years old (13 to 20 years old). The locations were left knee in 11 cases, right knee in 12 cases. The disease course was 1-28 weeks (mean 15 weeks). All patients had patellar instabil ity sense and knee arthralgia during strenuous exercise. Preoperative, the International Knee Documentation Committee (IKDC) score and Lysholm score were 48.30 ± 5.77 and 50.80 ± 7.61. The congruence angle, lateral patellar angle, and Q angle were (9.00 ± 2.46), (2.94 ± 2.55) and (19.10 ± 4.16)°. All of the patients experienced the operation of reconstruction of MPFL with trabs of medial soft tissues (medial patellar retinaculum, joint capsule and vastus medial is obl ique muscle fiber) through arthroscope. Results All the wounds healed by first intention, and no postoperative early compl ication occurred. All cases were followed up 19 months on average (12 to 24 months). Apprehensive test and patella tilt test were negative. The range of motion returned to normal. There was no recurrence of dislocation after operation. At 12 months after operation, the congruence angle, lateral patellar angle, and Q angle were (—7.03 ± 0.60), (11.00 ± 3.47) and (11.30 ± 1.90)°; the IKDC score and Lysholm score were 93.20 ± 3.51 and 94.10 ± 4.26. There were statistically significant differences between preoperation and postoperation (P lt; 0.05). Conclusion Arthroscopic reconstruction of MPFL with trabs of medial soft tissues can improved obviously the affected limb function in treatment of patellar instabil ity of adolescence.
Objective To assess the influence of soy foods intake in Adolescence on the female adult’s breast cancer. Methods Literatures about the influence of soy foods intake in Adolescence on the female adult’s breast cancer were retrieved in The Cochrane Library, MEDLINE, EMbase, CNKI, VIP, WanFang Data and CBM from the date of their establishment to August 2011, meanwhile, the references of included papers were also retrieved. The data were extracted according to the inclusion and exclusion criteria by two reviewers independently, the quality of the included studies was assessed according to the Cochrane Newcastle-Ottawa scale and GRAEDprofiler 3.2.2, and meta-analysis was conducted by using Stata 11.0. Results A total of 6 studies involving 6 609 patients and 79 538 controls were included. The results of meta-analyses showed that compared with the non-intake or low intake of soy foods in Adolescence, high soy foods intake in Adolescence was associated with lower risk of breast cancer (OR=0.816, 95%CI 0.670 to 0.993); In the subgroup analysis, soy foods intake in Adolescence was more effective to prevent premenopausal (OR=0.661, 95%CI 0.550 to 0.796) rather than post-menopausal (OR=0.782, 95%CI 0.486 to 1.259) breast cancer; and the effects of soy foods intake in Adolescence were not significantly different between the eastern (OR=0.793, 95%CI 0.569 to 1.105) and western (OR=0.837, 95%CI 0.743 to 0.943) women. Conclusion Soy foods intake in Adolescence may be associated with a small reduction in the risk of adults’ breast cancer, especially for the premenopausal women, though there is no difference between the eastern and western women. However, restricted by quantity and quality of the studies, this conclusion should be confirmed by more studies.
