One thousand four hundred and twenty four patients with breast cancer were treated in our hospital from 1980 to 1993. The authors analysed the clinical date of this patients. The results showed that 1193 patients (84.4%) had menopause after 45 years old, 840 patients (59.4%) had menorrhea more than 30 years, 980 patients (80.5 %) had their first pregnancy after 25 years old, and 912 cases (74.9 %) had no history of breast feed. Breast cancer is related to genetic factors, other breast disease, mental factors and trace elements in human hair. The study of breast cancer and its relative factors can be expected to open a new road for the treatment and prevention of this disease.
Objective To explore the clinical epidemiological characteristics of the lung infection after orthotopical liver transplantation. Methods The clinical data included infection morbidity, mortality, infectious times and relative factors, clinical manifestations, the bacterial strains and distributions of the pathogens, the bacterial resistances of the 53 liver transplantation recipients from 2003.3～2006.12 were summarized and analyzed retrospectively. Results Among 53 recipients, 33 developed lung infectious and 6 died .The mobidity was 62.3% and mortality was 18.2%, with a OR of 1.0. Lung infection predominantly occurred in the first month, especially in the first week after transplantation.There were many factors related to lung infections.Various pathogens, especially Klebsialla, Escherichia Coli and Staphylococus Hominis were isolated from sputum, airway suction drainages and throat swabs. Most of the G- bacteria were sensitive to aminoglycosides,β lactam and lactamase compounds and carbapenems while G+ bacteria were sensitive only to glycopeptides. All the bacteria were resistant to quinolones, β lactams of third and forth generation. Conclusions After liver transplantation, the morbidity and mortality of the lung infections are high.The infections develope at earlier stage, manifest nontypical clinical features.Many factors are revealed to be relevant to the lung infections,meanwhile, various drug-resistant pathogen strains are isolated.
Objective To explore the relative prognostic factors of Tile C pelvic injury after iliolumbar fixation. Methods Between March 2007 and March 2010, 60 patients with Tile C pelvic injuries were surgically treated with iliolumbar fixation, including 39 males and 21 females with an average age of 37 years (range, 17-66 years). Of them, 27 cases were classified as Tile C1, 20 as Tile C2, and 13 as Tile C3. The preoperative injury severity score (ISS) was 12-66 (mean, 29.4). The time from injury to surgery was 2-25 days (mean, 8.1 days). Iliolumbar fixation was performed in all patients. Unconditional logistic analysis was used to analyze the relationship between the age, sex, body mass index (BMI), operation opportunity, the preoperative combined injury, classification of fracture, the postoperative complication, reduction outcome, sacral nerve injury, and the time of physical exercise and the prognosis. Results All 60 patients were followed up 12-56 months (mean, 27.3 months). Infection of incisions occurred in 12 cases and were cured after dressing change; healing of incision by first intention was obtained in the other patients. Delay sacral nerve injury was found in 15 patients, 6 patients underwent nerve decompression, and 9 underwent conservative treatment. Ten patients had nail protrusion of Schanz screws at the posterior superior illac spine, and 3 patients had pain, which was relieved after removal of the internal fixator. One patient had bone-grafting nonunion of sacroiliac joint, which was improved by pressured bone graft. Five patients had the beam breakage without significant effect. Six patients had deep vein thrombosis, among them 4 underwent filter and 2 underwent nonsurgical treatment. The healing time of fracture was 3-6 months (mean, 3.9 months). According to the Matta function score, the results were excellent in 31 cases, good in 24 cases, fair in 3 cases, and poor in 2 cases with an excellent and good rate of 91.7% at last follow-up. Majeed score was 58-100 (mean, 86), 28 were rated as excellent, 12 as good, 16 as fair, and 4 as poor with an excellent and good rate of 66.7%. The logistic analysis showed that the age, sex, BMI, and postoperative complications were not prognostic factors; early operation (within 10 days), early function exercises (within 7 days), the better reduction quality, and the less sacral nerve injury were in favor of prognosis; and the worse preoperative combined injury and pelvic injury were, the worse the prognosis was. Conclusion Operation opportunity, the preoperative combined injury, reduction outcome, sacral nerve injury, and the time of physical exercise are all significantly prognostic factors of Tile C pelvic injuries
