BACKGROUND:In vitro experiments suggest that LIM mineralization protein-1 (LMP-1) gene can increase the expression of LMP-1 protein in osteoporotic bone marrow mesenchymal stem cells. OBJECTIVE:To investigate the LMP-1 expression in osteoporotic bone marrow mesenchymal stem cells transfected with RV-LMP-1-GFP in vitro. METHODS:Twelve SD female rats were selected and subjected to bilateral ovariectomy for establishment of osteoporosis models. After 2 months of feeding, bilateral femurs, tibiae, and humeri of rats were taken to isolate and culture bone marrow mesenchymal stem cells. Passage 3 cells were taken and randomly divided into ovariectomized group and LMP-1 transfection group. Another six rats only underwent removal of the same amount of fat tissue around the ovary, and passage 3 cells which were harvested as those in the former two groups served as sham group. RT-PCR and western blot assay were performed to determine the expression of LMP-1 protein and mRNA. RESULTS AND CONCLUSION:Under an inverted fluorescence microscope, transfected bone marrow mesenchymal stem cells from osteoporotic rats showed green fluorescent expression. The three groups al could express LMP-1 at the protein and mRNA levels. The expression levels of LMP-1 protein and mRNA in the LMP-1 transfection group were significantly higher than those in the ovariectomized group and sham group (P<0.05), but there was no statistical difference between the latter two groups (P>0.05). The successful expression of the RV-LMP-1-GFP gene in osteoporotic SD rat bone marrow mesenchymal stem cells was realized at the protein and mRNA levels;moreover, the expression of LMP-1 was increased dramatical y. These findings indicate that LMP-1 gene is successful y transferred into osteoporotic SD rat bone marrow mesenchymal stem cells, and significantly elevates the expression of LMP-1 mRNA and protein.

OBJECTIVETo investigate the effects of butyl alcohol extract of Baitouweng decoction ( BAEB) on yeast-to-hyphae transition of Candida albicans isolates from vulvovaginal candidiasis (VVC) in alkaline pH.

METHODSerial 2-fold dilution assay was used to determine the minimal inhibitory concentrations (MICs) of Baitouweng decoction extracts against C. albicans isolates from VVC, XTT assay was applied to determine the metabolic activity of C. albicans hypha treated by BAEB for 6 h. The morphological change of C. albicans treated by BAEB was inspected at different pH by inverted microscope, fluorescence microscope, scanning electron microscopy (SEM). Solid agar plate and semi-solid agar were utilized to evaluate colony morphology and invasive growth of C. albicans, respectively. Quantitative Real-time PCR (qRT-PCR) was adopted to observe the expressions of hyphae-specific genes including HWP1, ALS3, CSH1, SUN41 and CaPDE2.

RESULTThe MIC of BAEB against C. albicans is less than that of other extracts; hyphae grow best at pH 8. 0; 512 mg · L(-1) and 1,024 mg · L(-1) BAEB could inhibit formation of hyphae and influence colony morphology. When treated by 512 mg · L(-1) and 1,024 mg · L(-1) BAEB, the colonies became smooth; while by 0 and 256 mg · L(-1) BAEB, the colonies became wrinkled. In semi-solid agar, the length of hyphae decreased steadily as the concentration of BAEB lowered. The expression of HWP1, ALS3, CSHl, SUN41 were downregulated by 5.12, 4.26, 3.2 and 2.74 folds, and CaPDE2 was upregulated by 2.38 fold.

CONCLUSIONBAEB could inhibit yeast-to-hyphae transition of C. albicans isolates from VVC in alkaline pH.

Near infrared (NIR) spectroscopy as a kind of rapid process analysis technology has been successfully applied in Chinese medicine pharmaceutical process. In this research, the technology was adopted to establish the rapid quantitative analysis models of main indicators from the Lonicera japonica and Artemisia annua alcohol precipitation process of Reduning injection. On-line NIR spectra of 142 samples from alcohol precipitation process were collected and the content of main indicators for each sample were detected through off-line HPLC. With eliminating outliers, determination of spectra pretreatment method and selecting optimal band, the NIR quantitative calibration model for each indicator was established using partial least squares (PLS). These models were used to predict the unknown samples from precipitation process of Reduning injection to achieve the goal of rapid detection. The results showed that the models were ideal. The correlation coefficients of models for neochlorogenic acid, chlorogenic acid, 4-O-caffeoylquinic acid and secoxyloganin were 0.973 872, 0.985 449, 0.975 509 and 0.979 790, respectively and their relative standard errors of prediction (RSEP) were 2.922 49%, 2.341 37%, 2.930 40% and 2.184 60%, respectively. This study indicated that the NIR quantitative calibration model showed good stability and precision, and it can be used in rapid quantitative detection of main indicators of efficacy in order to on-line monitor the alcohol precipitation process of Reduning injection.

Background About one third of congenital cataract is associated with inheriting factor.The inherited heterogeneity has been found in congenital cataract.To seek the pathogenic gene is essential for the gene therapy. Objective Present study was to map and identify the causal gene for autosomal dominant congenital cataract (ADCC) in a Chinese family. Methods The clinical features of all affected members in this family were examined.Blood samples were collected from eleven family members for genetic linkage analysis.Polymorphic microsatellite markers were selected from the regions which harbor all known loci linked with ADCC.Universal fluorescent-labeled M13 primer was used in linkage analysis.Direct genomic sequencing was used to evaluate the candidate gene for example CRYBB2 gene.This study followed Helsinki Declaration and was proved by Tianjin City Ethic Committee.Written informed consent was obtained from each SUbject before any medical procees. Results The maximum two-point LOD score of 1.20 was obtained for marker D22S315 (θ=0).The LOD score of 0.6 was obtained for marker D16S3068.No mutation in all exons of CRYBB2 gene was found in the family. Conclusion CRYBB2 gene associated with ADCC was excluded from the family.A genome-wide linkage screening should be conducted.Genotyping with microsatellite markers using Universal fluorescent-labeled M13 primer can decrease the cost and obtain the same result.

Objective To screen the optimized Buyang Huanwu Decoction (BYHWD);To verify it. Methods H2O2 was used to induce PC12 cell oxidative stress models. MTT method was used to determine the prevention effects of BYHWD at different concentrations (0.1, 0.2, 0.5, 1.0, 2.0, 3.5 mg/mL) on in vitro oxidative stress cell models to define the optimized concentration. Orthogonal design was used to divide BYHWD single medicine into decomposed BYHWD groups, control group (only with DMEM), normal group (without H2O2 and medicine processing), and model group, to investigate the protective effects on PC12 cells. Optimized BYHWD was screened to decide the compatibility ratio of each medicine. MTT was used to detect the cell survival rate in each group. Middle cerebral artery occlusion was used to replicate MACO rat models. SD rats were randomly divided into sham-operation group, model group, BYHWD group and optimized BYHWD high-, medium-and low-dose groups. Each medication group was given relevant medicine for gavage. The screened results were verified. Results Compared with other decomposed BYHWD groups, the protective effects of the compatibility of Astragali Radix+Chuanxiong Rhizoma+Pheretima on PC12 cells was the best (P<0.05), which was nearly equaled to BYHWD. Compared with the model group, BYHWD and the optimized one could evidently reduce cerebral cortex infarction area and improve the impaired brain edema (P<0.05), and the medium-dose group was the best. Conclusion The optimized BYHWD ratio is:Astragali Radix:Chuanxiong Rhizoma:Pheretima=10:3:1.
