However, little infor- mation is available about the pharmacodynamic basis. The antitumor, immunomodulatory and free radical scavenging effects of SCP were evaluated in this study. Transplanted tumor in vivo method was used to determine the antitumor effect. The effects on spleno- cyte proliferation and phagocytosis of macrophages in tumor-bearing mice were measured by the MTT method and the phagocytizing cock red blood cell (CRBC) method respectively. The scavenging activities of SCP on DPPH and hydroxyl radicals in vitro were investigated. It was found that the medium-dose and high-dose of SCP could significantly inhibit the growth of transplanted hepatic tumor of murine hepatocarcinoma cell line H22, and promote proliferation of splenocytes and phagocytosis of macrophages. SCP possessed noticeable scavenging activities on DPPH and hydroxyl radicals. The antiturnor effects of SCP might be achieved by im- proving immune system and scavenging free radicals, which is in accordance with the viewpoint of traditional Chinese medicine in promoting the body resistance and eliminating pathogenic factors for cancer treatment.展开更多

In this study, we set out to present the characteristics and classification of antibiotics recommended for children according to WHO, EMA and EBM. Also, the aim of this study was to analyze the most prescribed pediatric antibiotics in 2013 in Republic of Macedonia compared with standard treatments. Presented data was collected according to the number of prescribed recipes of pediatric dosage forms covered by the Fund of Republic of Macedonia. The obtained results showed that the most prescribed pediatric antibiotic is amoxicillin with clavulanic acid (875mg + 125mg) in form of tablet, with 280 863 prescribed recipes which corresponds to the recommendations of EBM.展开更多

We used this estimator to construct a prior model of the image intensity and curvature profile of the structure from training images. When segmenting a novel image similar to the training images, the technique of narrow level set method is used. The higher dimensional surface evolution metric is defined by the prior model instead of by energy minimization function. This method offers several advantages. First, SVM for density estimation is consistent and its solution is sparse. Second, compared to the traditional level set methods, this method incorporates shape information on the object to be segmented into the segmentation process. Segmentation results are demonstrated on synthetic images, MR images and ultrasonic images.展开更多

Questionnaires were given to doctors and patients to study the essential factors (indicators and timing) of Sui Zheng Shi Liang strategy in the treatment process of type 2 diabetes (T2DM). METHODS: Two questionnaires were designed for diabetes patients and their doctors. The questionnaires included the most important indicators for determining the patient's condition, the ability of TCM in treating T2DM, the length of time it takes for TCM to be effective, and when to adjust the prescription dosage.The frequency of answers was calculated, summarized, and analyzed after the survey. RESULTS: Twenty questionnaires from doctors and 90 questionnaires from patients were included in the analysis. Doctors and patients recognized thatTCM could decrease blood glucose, improve syndromes, and delay complications. Doctors were mainly concerned about glycosylated hemoglobin, while the patients were concerned about fasting plasma glucose for determining whether treatment was effective. Doctors also paid attention to changes in blood sugar and syndromes 2 weeks after medication was given as the indication to adjust the prescription dosage, while patients were concerned about these factors in 4 weeks.The prescription should be regulated when there are side effects or the medication is ineffective. CONCLUSION: The essential factor in the treatment process of T2DM in Sui Zheng Shi Liang strategy is that if fasting blood glucose level did not decrease after 4 weeks of treatment, the Chinese medicine prescription should be adjusted.展开更多
