Methods Nine patients had premature ejaculation whose frenula were short. Two patients suffered unsatisfied intercourse whose frenula were injured and departed 12 and 6 months ago. Three males endured premature ejaculation whose frenula were hurt in coition 30 min ago.We prolonged short frenulum and reconstructed the ruptured frenulum. To the fresh wound,we debrided the cut,then sutured the injured frenulum vertically. Results Investigated 3 to 6 months,all patients got satisfied sexual intercourse. Conclusion Frenulum is important in erecting time.展开更多

Methods： The data of 101 patients with colorectal cancer in Tianjin Medical University Cancer Institute and Hospital from May 2011 to November 2011 was analyzed. The photos of all patients＇ frenulum labii superioris were taken. Nodule and eminence on frenulum labii superioris were the positive standard. Biopsy and pathological testing for the nodule were carried out on one patient with large nodule on frenulum labii superioris. Results： Patients with positive frenulum labii superioris had a higher risk of recurrence and/or metastasis than patients with negative frenulum labii superioris. There were no significant differences in diagnosis of recurrence and/or metastasis between the status of frenulum labii superioris and the traditional diagnostic criteria （P=0.238）. The Kappa was 0.606 （P〈0.001）. The sensitivity was 76.0% and the specificity was 85.4%. The pathological report demonstrated that the nodule on frenulum labii superioris was mucosal excrescence with normal structure. Conclusion： Nodule and eminence on frenulum labii superioris are potential diagnostic markers for metastatic colorectal cancer.展开更多
