OBJECTIVE: To prepare cholesterol-PEG-modified amphotericin B liposomes and amphotericin B liposomes, and evaluate their encapsulation efficiency and pharmacokinetics. METHODS: It was employed to prepare both kinds of liposomes with the film-evaporation, the dynamic light scattering techniques and Ultrafree-CL were used to determine the mean diameter and the encapsulation efficiency, respectively. Pharmacokinetics was evaluated in Wista rats. RESULTS: Mean diameter of the liposomes was (115 ± 20) nm, and the encapsulation efficiency was over 99.9%. Moreover, the pharmacokinetic study in rats indicated that cholesterol- PEG-modified liposomes could significantly increase the ρmax and AUC. CONCLUSION: Amphotericin B liposomes prepared by film-evaporation method have high encapsulation efficiency, and cholesterol-PEG modification can prolong the circulation time of amphotericin B in vivo.

After half a century of self-innovation, the integrated traditional Chinese and Western medicine has witnessed the great progress in both clinical and basic research. However, the theoretical system of the integrative medicine does not break through the limitations of traditional Chinese medicine and Western medicine, which hinders its implication in experimental study and clinical work. In view of the current situation, to develop the integration of traditional Chinese and Western medicine further, efforts should be made in such aspects as educational system construction, talent personnel training, improving the level of clinical practice and corresponding basic research as well as the establishing the basic theoretical system.

Analyzed the prescriptions for phlegm retention syndrome that built by Ma Peizhi by the association rules and clustering algorithm, the frequency of drug usage and the relationship between drugs could be get. And from that we could conclude the experiences for phlegm retention syndrome of Ma Peizhi of menghe medical genre. The results of the analysis were that 18 core combinations were dig out, such as Citri Exocarpium Rubrum-Eriobotryae Folium-Citri Reticulatae Pericarpium. And there were 9 new prescriptions were found out such as Aurantii Fructus-Citri Exocarpium Rubium-Eriobotryae Folium-Citri Reticulatae Pericarpium. The results of the analysis were proved that Ma Peizhi of Menghe Medical Genre was good at curing phlegm retention syndrome by using the traditional Chinese medicine of mild and light, such as the medicines of mild tonification, and clearing damp and promoting diuresis.

The clinical prescriptions of hemoptysis that built by Menghe physician Ma Peizhi were collected, and were analyzed by the method of unsupervised data mining, such as association rules and clustering algorithm. From the prescriptions, we got the frequency of drugs, the association rules among drugs, 10 core drug combinations and 5 new prescriptions. Accordingly, after the analysis, Menghe physician Ma Peizhi had rich experience in the treatment of hemoptysis. His therapy for hemoptysis was clearing heat and moistening lung, dispel heat from blood to stop bleeding, and enriching yin and blood. And we can also make a conclusion that the TCM inheritance support system is of great practical value for minning the old doctors' clinical experiences.
