We presented a new method for vessel segmentation and vascular structure recognition for coronary angiographic images. During vessel segmentation, a new vessel function was proposed to attain vessel feature map. Then the region growing algorithm was implemented with an automatic selection of seed point, extraction of main vessel branch, and vessel detail repairing. In the algorithm of vascular structure recognition, a fuzzy operator was used, which can detect the structures of vascular segments, bifurcations, crosses, and tips. The experimental results indicated that there was about 5 percent larger vessel region which was extracted by the proposed segmentation method than that by the simple region growing algorithm, and several thinner vessels were resumed from the lower gray region. The results also indicated that the fuzzy operator could correctly infer the simulative and real vessel structure with 100% and 90.59% correctness rate on the average, respectively.

Objective:To explore the safety of cyclophosphamide combined with taxane chemotherapy in triple-negative breast cancer patients with chronic renal failure and the management strategy of complications.Methods:Data of 8 patients with triple-negative breast cancer and chronic renal failure admitted to our hospital from Jun 2016 to Dec 2019 were retrospectively analyzed.Results:Eight patients received standard cyclophosphamide combined with taxane (TC regimen) chemotherapy after operation, 5 of which received docetaxel 75 mg/m 2 + cyclophosphamide 600 mg/m 2, and 3 received albumin paclitaxel 260 mg/m 2+ cyclophosphamide 600 mg/m 2, during chemotherapy, only leukopenia, hair loss and gastrointestinal reactions occurred in grades 3 to 4, and the incidence was 25%, 25% and 12%, respectively. Four patients adjusted the dosage due to adverse reactions. One patient quit, the remaining patients successfully completed 4 cycles of chemotherapy. The average serum creatinine before chemotherapy was (498±63) μmol/L, and after chemotherapy, it was (518±61) μmol/L ( t=-2.335, P>0.05). Conclusions:Combined with chronic renal failure is not a contraindication to postoperative chemotherapy for patients with breast cancer. It is safe to choose standard TC regimen and adjust the dose of adjuvant chemotherapy for patients with triple-negative breast cancer.

Abstract: To report a case of Aspergillus salwaensis-induced spinal infection and its laboratory detection. The inflammatory granulation and necrotic tissue samples of a patient with spinal infection were collected from, the Affiliated Hospital of Chengde Medical College on June 17, 2020 for direct smear microscopy and culture, and the isolated strain was identified by microscopy by smear staining, matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS), molecular identification and in vitro antifungal susceptibility test. The patient was 62 years old female and presented with recurrent chest and back pain with no obvious cause. The initial diagnosis was spinal infection, after 7 days of treatment with levofloxacin, the effect was not good. Surgery was then performed remove the lesion via posterior thoracic debridement, and fungal hypha was observed under microscope in tissue specimens. The isolated strains had no typical structure, MALDI-TOF-MS was used for identification for many times, but there was no identification result. After 7 days of fluconazole treatment, the patient's condition improved, and her chest and back pain were alleviated compared to before surgery. The patient was discharged and followed up in the outpatient department, the fungus was later identified as Aspergillus salwaensis by sequence analysis of the internal transcribed spacer (ITS) gene sequencing, and the patient's antifungal medication was changed to voriconazole after with the attending physician. The patient consciously recovered well with no pain in the operative area and normal spinal activity at 1 year follow-up. The possibility of spinal fungal infection should be considered in patients with back pain without a clear cause and poor response to routine antibiotic treatment. Direct smear report of microscopic results are very important for guiding clinical antibiotic selection for rare filament fungi with atypical colony and microscopic morphology and unsuccessful MALDI-TOF-MS identification, molecular biological methods such as ITS sequence analysis can be helpful for early identification of the fungal species, improving identification speed.
