ABSTRACT
The characteristics of public health teaching are discussed in this paper from the aspects of public health curriculum system and difficulties of public health curriculum. The application status of flipped classroom, MOOC, distance learning, online course, Elearning, UMU online education platform and other smart teaching methods in public health teaching are summarized. It is suggested that the level of smart public health teaching should be improved from the perspectives of learning autonomy, deep integration of teaching and technology and construction of smart classrooms.
ABSTRACT
Objective:To analyze results of microbiological culture of lesion exudates and drug sensitivity test in patients with pemphigus, and to optimize the management protocol of pemphigus.Methods:Inpatients with pemphigus were collected from Department of Dermatology and Venereology, the First Affiliated Hospital of Anhui Medical University from January to December in 2008, and the results of microbiological culture of skin lesion exudates and drug sensitivity test were retrospectively analyzed.Results:A total of 176 patients were collected, and skin lesion exudate culture yielded 25 kinds of bacteria and 11 kinds of fungi in 156 (88.64%) patients. Of the 156 patients, 1 kind of pathogen was yielded in 104 (66.67%), and 2 or more kinds of pathogens were yielded in 52 (33.33%). Gram-positive cocci were detected in 134 (76.14%) cases, including Staphylococcus aureus in 80, Staphylococcus hemolyticus in 21, and Staphylococcus epidermidis in 16; Gram-negative bacilli were detected in 66 (37.50%) cases; fungi were detected in 24 (13.64%) cases. In addition, 89 (93.68%) of 95 relapsed patients showed positive culture results, 67 (82.72%) of 81 patients with newly developed pemphigus had positive culture results, and the positive rate significantly differed between the two groups ( χ2 = 5.22, P <0.05). Drug sensitivity test for Staphylococcus aureus isolates showed that 71 (97.26%) of 73 were sensitive to vancomycin, 69 (97.18%) of 71 to linezolid, and 61 (87.14%) of 70 to rifampin. Conclusion:Cutaneous infection, especially Gram-positive cocci infection, is very common in patients with pemphigus, and Staphylococcus aureus clinical isolates were highly sensitive to vancomycin, linezolid and rifampicin.
ABSTRACT
Objective To investigate the efficacy and safety of Bevacizumab (Bev) combined with chemotherapy protocols in the patients with metastatic colorectal cancer (mCRC).Methods 43 patients with mCRC were treated with Bev combined with various of chemotherapy protocols.The efficacy was assessed based on Response Evaluation Criterion for Solid Tumors (RECIST),and the adverse events were evaluated according to National Cancer Institute-Common Toxicity Criterion for Adverse Events (NCI-CTCAE) 3.0.Results The data of 43 patients (16 males and 27 females) were analyzed.17 patients achieved partial remission (PR),19 patients stable disease (SD) and 7 patients progressive disease (PD).The median progression-free survival (PFS) time was 10.3 months.The major of 3-4 adverse events included leucocytopenia,neutropenic febrile,and nausea/vomiting.Bey-associated adverse events were proteinuria,hypertension,rhinorrhagia,hemorrhagic hemorrhoid,menstrual blood increased,gastrointestinal perforation and venous thrombosis.Conclusions Bey combined with various chemotherapy protocols is more effective for patients with mCRC.Most patients can tolerate the side effects of the combined treatment.The long-term effects of the combined treatment need to be followed up.
