OBJECTIVE:To provide reference for rational use of human serum albumin for surgical inpatients. METHODS:The utilization of human serum albumin for surgical inpatients in a hospital during Jan.-Mar. 2014 was analyzed and evaluated by UHC Guidelines for the Use of Album,Nonprotein Colloid,and Crystalloid Solutions(2010 edition)and European Immune Globu-lin and Albumin Use Recommendation. RESULTS:Among the 556 patients,totally 895 human serum albumin application were con-ducted,mainly involving development of gastrointestinal surgery(29.7%),hepatobiliary surgery(25.9%)and cardiothoracic sur-gery(13.1%). The main reasons were correcting hypoalbuminemia(62.9%),followed by albumin supplemented during major sur-gery(7.9%)and alleviating ascites in patients with cirrhosis(4.4%);only 95 applications(10.6%)were considered appropriate. The most prevalent inappropriate reason was for correcting hypoalbuminemia. CONCLUSIONS:Human serum albumin in the surgi-cal inpatients in the hospital shows a large amount,and low consistent rate between indications and guidelines. The rational stan-dardized utilization of human serum albumin should be strengthened.

Objective To investigate the antitumor effect and its mechanism of microbubble contrast combined with Mitoxantrone exposed to low-frequency ultrasound on human breast cancer cell MCF-7. Methods MTT method was applied to examine the growth inhibition of MCF-7 treated with Mitoxantrone. MCF-7 cells were randomly divided into 4 groups:Mitoxantrone group (group D), ultrasound+Mitoxantrone group (group U+D), ultrasound+microbuble +Mitoxantrone group (group U+M+D) and control group (group C). The cytoactive of each group was examined with MTT. The intracellular drug content in each group was measured with high performance liquid chromatography. The morphology of MCF-7 cells apoptosis was observed with transmission electron microscopy (TEM). Results The IC_(50) of Mitoxantrone was 2.87 μg/ml. The differences of cytoactive among all groups were significant (P<0.05). The intracellular drug content of group U+M+D was higher than that of group U+D, and the latter was higher than that of group D. The morphological changes of apoptosis were observed with TEM. Conclusion Low-frequency ultrasound can promote intracellular drug content as to enhance the sensitivity of chemotherapy drugs on tumor cells, and this effect can be enhanced by microbubble contrast exposure to low-frequency ultrasound.

Academic Journal of Second Military Medical University 2019;40(5):497-506
Objective To propose a conditional random field (CRF) model based on the new word segmentation method Re-entity, and to compare with bi-directional long short-term memory neural network (BiLSTM)-CRF and Lattice-long short-term memory neural network (LSTM). Methods After analyzing the existing entity recognition methods, we proposed CRF method based on Re-entity, BiLSTM-CRF and Lattice-LSTM for the China Conference on Knowledge Graph and Semantic Computing in 2018 (CCKS2018) task one: Chinese clinical named entity recognition, and trained character vector sets at different parameter levels based on different corpora. The comparative experiments on model performance were carried out in the different neural network models for each methods. Finally, the comparative study was carried out based on different input lengths such as the sentence level and the text level. Results Re-entity method can improve the performance of CRF model. Lattice-LSTM model based on sentence level achieved a strict F1-measure of 89.75% on this task, which was higher than the highest F1-measure (89.25%) on the task one of CCKS2018. Conclusion The CRF model based on Re-entity can effectively improve the recognition rate of traditional Chinese medicines in electronic medical records by using normalized Chinese clinical drug. Re-entity method can improve the error accumulation caused by word segmentation in data preprocessing. Lattice structure can better combine the latent semantic information of characters and word sequences. At the same time, sentence-level input can effectively improve the recognition accuracy of neural network models.
