Objective To investigate the infection prevention effect of prophylactic use of antibiotics for cancer inpatients with leukocyte count ≤ 1 × 109/L.Then to provide the basis for rational use of antibiotics.Methods It was retrospectively surveyed that the infection situation and prophylactic usage of antibiotics in the 426 cancer inpatients with leukocyte count ≤ 1 × 109/L caused by radiotherapy and chemotherapy.Results In the 426 inpatients,the infection rates of patients with and without prophylactic use of antibiotics were 11.0％ and 20.9％ respectively.The difference was statistically significant (x2 =6.815,P =0.009).The leukocyte count median values of patients with and without infection were 0.73 × 109/L and 0.77 × 109/L respectively.The difference had no statistical significance(Z =-1.257,P =0.209).The main infection sites were lower respiratory tract,upper respiratory tract and gastrointestinal tract with infection rates of 48％,12％ and 11％,respectively.The top five pathogens were Klebsiella pneumonia,Enterobacter cloacae,Escherichia coli,Enterobacter aerogenes and Staphylococcus aureus.The most use of antibiotics were cephalosporin.Conclusion When the leukocyte counts of cancer inpatients are less than or equal to 1 × 109/L induced by chemotherapy and radiotherapy,reasonable prophylactic use of antibiotics can reduce hospital infection rates.

OBJECTIVE: To investigate the myeloid differentiation factor 88 (MyD88) expression in laryngeal carcinoma and its clinical significance. METHOD: Fifty-one patients with laryngeal carcinoma were collected, and all patients were confirmed by pathological diagnosis results. The expression of MyD88 protein was detected by immunohistochemical method in laryngeal cancer and its adjacent tissues to investigate the correlation among MyD88 expression, clinicopathological characteristics and prognosis of patients. RESULT: The positive expression rate of MyD88 in laryngeal cancer tissues was 68.6%, significantly higher than that in normal tissues adjacent to carcinoma of which positive expression rate was 11.8%; MyD88 positive rate had nothing to do with laryngeal cancer patients age, sex, differentiation and tumour location (all P > 0.05), but correlated with clinical stage (P < 0.01) and lymph node metastasis (P < 0.05). In addition, the study also found that the expression of MyD88 quantity was inversely proportional with the five-year survival rate. The survival rate of patients with higher expression of MyD88 was significantly lower than that of patients with lower expression (P < 0.05). CONCLUSION MyD88 may be an important participant in the pathogenesis of laryngeal carcinoma, MyD88 targeted therapy may improve the prognosis of patients with laryngeal cancer.
