Objective To explore the efficacy of mycophenolate mofetil (MMF), which is a kind of immuno-suppressant drugs, on the treatment of Connective tissue diseases-pulmonary arterial hypertension (CTD-PAH). Methods Medical charts of eleven cases of hospitalized patients who were diagnosed as CTD-PAH and treated by MMF in Beijing Chaoyang Hospital affiliated to the Capital Medical University, from January 2014 to June 2016 were collected and analyzed. Results In the 11 cases of CTD-PAH, the systemic lupus erythematosus (SLE) related pulmonary hypertension (SLE-PAH) were 7, while the systemic sclero-derma associated pulmonary hypertension (SSc-PAH) were 2, and rheumatoid arthritis related pulmonary hy-pertension (RA-PAH) was 1, and the mixed connective tissue disease related pulmonary hypertension (MCTD-PAH) was 1. All patients were women, and the average age was (40 ±14) years, and the average duration of PAH was (34 ±35) months. The combination therapy of corticosteriods and MMF was applied to 7 cases, meanwhile the therapy of corticosteriods, MMF and bosentan was used in 1 case, corticosteriods, MMF and sildenafil was prescribed for 3 cases, and symptoms of the patients alleviated. Except for one case having been followed up for 7 months and one for 6 months, 9 patients completed the 1-year follow-up, and the survival rate was 100%(9/9). Notably, one patient, who had been alleviated for 111 months with therapy of corticosteriods and MMF, adopted the combination therapy of corticosteriods, MMF and bosentan for aggravated chest distress, and became stable eventually. Conclusion MMF may have therapeutic effects on inducing and even maintaining the stabilization of CTD-PAH.

Objective To study the effects of Cad-Ⅱgene on osteogenic differentiation of human mesenchymal stem cells in vitro. Methods The human marrow mesenchymal stem cells (hBMSCs) were isolated and cultured in vitro before they were divided into 2 groups. In the transfeetion group, the hBMSCs were transfeeted with Cad- Ⅱgene;in the simple osteogenic inducement group, they were cultured in the condition medium. Then the expressions of Cad- Ⅱ protein were determined and the alkaline phosphatase (ALP) activities and the expressions of ostcocalein were measured at 3, 7, 14 and 21 days for comparison between the 2 groups. Results The ALP activity and positive expression of osteoealcin were regulated significantly higher in the transfeetion group than in the simple osteogenic inducement group at different times (P <0.05). The mineralized nodes began to appear at 14 days in the 2 groups and increased with time. Conclusion Cad-Ⅱgene transfeetion can promote differentiation of hBMSCs into the osteoblasts.

In the present study, packaging system composed of pAAV-CMV-GFP, pAAV-RC and pHelper were transfected into human embryonic kidney 293 cells (HEK293 cells) mediated by polyethyleneimine (PEI) to explore an optimal transfection condition. Different total plasmid DNA dosages (1, 2, 3, 4, 5, 6 μg) and different PEI/Plasmid ratios (1:1, 3:1, 5:1, 7:1) were tested with detection of green fluorescence protein (GFP) with ImagePro Plus6. 0 Software. Then transfection efficiency of the optimized transfection system was further observed for different time periods(12, 24, 36, 48, 60, 72 h). The results showed that total plasmid dosage of 4 μg/well with PEI/plasmid ratio of 3 : 1-5 : 1 was an efficient transfection condition. Transfection efficiency-time curve was an S-shaped curve. Transfection efficiency reached a plateau at 60 h after transfection. The optimized conditions for PEI-mediated transfection at the optimal time result in enhanced transfection efficiency of triple plasmid into HEK293 cells.

A set of central composite design experiments were designed by using four factors which were ethanol amount, ethanol concentration, refrigeration temperature and refrigeration time. The relation between these factors with the target variables of the retention rate of schizandrol A, the soluble solids content, the removal rate of fructose and the removal rate of glucose were analyzed with Bayesian networks, and ethanol amount and ethanol concentration were found as the critical process parameters. Then a network model was built with 2 inputs and 4 outputs using back propagation artificial neural networks which was optimized by genetic algorithms. The R2 and MSE from the training set were 0.983 8 and 0.001 1. The R2 and MSE from the test set were 0.975 9 and 0.001 8. The results showed that network analysis method could be used for modeling of Schisandrae Chinensis Fructus ethanol precipitation process and identify critical operating parameters.

A study on the microbial transformation of glycyrrhetinic acid (GA) was conducted by a fungus, Cunninghamella blakesleeana CGMCC 3.970 systematically. After incubation with the cell cultures of C. blakesleeana CGMCC 3.970 at 25 degrees C for 7 days on a rotary shaker operating at 135 r x min(-1), GA was converted into one major product and five minor products. The products were extracted and purified by solvent extraction, macroporous adsorbent resin, silica gel column chromatography, and semi-preparative RP-HPLC chromatography. Their structures were identified as 3-oxo-15α-hydroxy-18β-glycyrrhetinic acid(1), 3-oxo-15β-hydroxy-18β-glycyrrhetinic acid (2), 7β,15α-dihydroxy-18β-glycyrrhetinic acid (3), 3-oxo-7β, 15α-dihydroxy-18β-glycyrrhetinic acid (4), 7β-hydroxy-18β-glycyrrhetinic acid(5) and 15α-hydroxy-18β-glycyrrhetinic acid(6) by the analyses of MS, 1H-NMR and 13C-NMR spectroscopic data respectively. Among them, 2 was a new compound. These results suggest that C. blakesleeana CGMCC 3.970 has the capability of selective ketonization and hydroxylation for GA.
