1. Preparation of Cholesterol-PEG-Modified Amphotericin B Liposomes and the Pharmacokinetics in Rats
Chinese Pharmaceutical Journal 2018;53(5):371-374
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.

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.

Objective To investigate the relationship between serum adiponectin and metabolic syndrome(MS) in children and adolescents with obesity and nonalcoholic fatty liver disease(NAFLD).Methods Four elementary schools and 4 middle schools were selected from Haidian district in Beijing with representative cluster sampling.Two hundred and eighty obese children(obese group),65 obese children with NAFLD(NAFLD group) and 264 normal weight children(healthy control group) aged 7 to 18 years were recruited from the 8 schools with uncompletely randomized sampling.Data including questionnaire,anthropometric measurements,B type ultrasonographic examination for liver were collected and fasting blood laboratory assay were determined.Variables including triglyceride(TG),adiponectin,alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were skewed distribution and natural logarithmical transformations were performed.Chi-square test for category and multiple binary Logistic regression analysis were used to statistical analysis.Results Body mass index(BMI) and waist circumference(WC) in obese group and NAFLD group were higher than those in healthy control group.All the chi-square tests for trend among the 3 groups were statistically significant(P
