Object To establish a method by high performance liquid chromatography/evaporative light scattering detector (HPLC-ELSD) for the determination of contents of D-fructose, D-glucose, and sucrose in Siwu Decoction (SWD). Methods Condensed SWD was analyzed by HPLC-ELSD after dilution, precipitation by ethanol. Results Condensed SWD, 1 mL, contained (33.4?1.5) mg of D-fructose, (24.2?0.9) mg of D-glucose and (112.7?6.1) mg of sucrose. The standard curves were linear within the range of 0.15—3.75 mg/mL for D-fructose and 0.15—5 mg/mL for D-glucose and sucrose. The recovery rates were 128.5% for D-fructose, 114.7% for D-glucose, and 124.7% for sucrose. The relative standard deviations (RSD) within-days were 3.0% for D-fructose, 3.2% for D-glucose, and 4.4% for sucrose. Conclusion SWD contains abundant monosaccharide and disaccharide. HPLC-ELSD can be used to analyse the monosaccharide and disaccharide in SWD.

In the present study, an ultra performance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC/Q-TOFMS) based on chemical profiling approach to evaluate chemical constitution between mixed decoction and co-decoction of monkshood-pinellia combination of the eighteen incompatible medications (Shi Ba Fan) was proposed. Two different kinds of decoctions, namely monkshood-pinellia co-decoction: water extract of the two herbs together, and monkshood-pinellia mixed decoction: water extract of each individual herbs mixed together, were prepared. Batches of these two kinds of decoction samples were subjected to UPLC/Q-TOFMS analysis, the datasets were processed with MassLynx 4.1 to holistically compare the difference between these two kinds of decoction samples. The most changed components during decocting were analyzed. Using the proposed approach, global chemical difference was found between co-decoction and mixed decoction, mesaconitine, aconitine and hypaconitine were identified as the most changed components (changed most significantly) during decocting. Result shows significant difference between two kinds of decoction samples, and the significant differences are probably related to the incompatibility of monkshood and pinellia.

Objective To evaluate the effect of abducens orthosis combined with walker on de-velopmental dysplasia of the hip ( DDH ). Methods A total of 126 patients (224 hips ) with DDH aged 6~36 months in Xiangya Hospital was randomly divided into 2 groups: an orthosis combined with walker group and an improved hip frog cast fixation group. Seventy patients (130 hips) were treated by the orthosis combined with walker and 56 patients (94 hips) were treated by the improved hip frog cast fixation. We compared the effect and complications of the 2 groups. Results The fine-ness rates of the orthosis combined with walker group and the improved hip frog cast fixation group were 89.2% and 90.4% , respectively, with no significant difference (P>0.05). The rate of femoral head osteonecrosis in the orthosis combined with walker group was significantly lower than that in the improved hip frog cast fixation group (1.5 % vs. 5.3 % , P<0.05) , but the re-dislocation rate in the former was significantly higher than that in the latter (6.9 % vs. 1.1% , P<0.05). Conclusion Both methods are effective for DDH. Orthosis combined with walker has a lower propor-tion of femoral head osteonecrosis, but a higher proportion of re-dislocation.

Objective To investigate the effects of component combination in Siwu Decoction (CCSWD) on the proliferation of human bone marrow stromal cell lines HFCL and hematopoiesis-related gene expression and to probe into the mechanism of the stimulative effects of SWD and CCSWD on the proliferation of HFCL cells. Methods MTT and FCM were used for assaying the proliferation potency and cell cycle of HFCL cells, respectively. A human hematopoiesis-related cytokine oligonuleotide microarray was prepared to investigate the diversity of gene expression of HFCL cells in SWD and CCSWD groups. Results The energy metabolism and proliferation potency of HFCL cells treated with CCSWD were more prompted than that of the control group. Meanwhile, the percentage of HFCL cells in G 0/G 1 phase treated with CCSWD was significantly lower, while the proliferation index (PI) was higher than that of the control group. Compared to the control group, expressions of IL 2-R?, NF-?B, and TPO were up-regulated in CCSWD group.Conclusion The proliferation of HFCL cells could be facilitated by CCSWD with up-regulating the expressions of IL 2-R?, NF-?B, and TPO.

In the present study, an ultra performance liquid chromatography coupled with time-of-fight mass spectrometry (UPLC-TOF/MS) based chemical profiling approach was used to evaluate chemical constitution between co-decoction and mixed decoction of ginseng and Radix Aconiti Praeparata. Two different kinds of decoctions, namely co-decoction of ginseng and Radix Aconiti Praeparata: water extract of mixed two herbs, and mixed decoction of ginseng and Radix Aconiti Praeparata: mixed water extract of each individual herbs, were prepared. Batches of these two kinds of decoction samples were subjected to UPLC-TOF/MS analysis. The datasets of t(R) m/z pairs, ion intensities and sample codes were processed with supervised partial least squared discriminant analysis (OPLS-DA) to holistically compare the difference between these two decoction samples. Significant difference between the two decoction samples was showed in the results of positive ion mode. The contents of hypaconitine and deoxyaconitine decreased, while that of benzoylmesaconine, benzoylhypaconine and dehydrated benzoylmesaconine increased in the samples of co-decoction of ginseng and Radix Aconiti Praeparata. The content of diester-diterpenoid alkaloids decreased, while that of monoester-diterpenoid alkaloids increased, which is probably the basis of toxicity-attenuated action when combined ginseng with Radix Aconiti Praeparata.

OBJECTIVE To study the mitochondrial toxicity effect of Radix Aconiti Lateralis Praepa?rata(Fuzi)on H9c2 cardiomyocytes. METHODS H9c2 cells were exposed to Fuzi decoction 6.25, 12.5,25,50 and 100 g·L-1 for 24 h. Fluorescence staining and CCK-8 assay were used to detect cell viability. H9c2 cells were exposed to Fuzi decoction 6.25,12.5 and 25 g · L-1 for 24 h,while the effect on mitochondrial membrane potential and reactive oxygen species(ROS)was detected by flow cytometry. The fluorescence molecular probe and laser scanning confocal microscope were used to observe the effect on Ca2+ in cells,Ca2+ and superoxide in mitochondria. The effect on ATP concentration in cells was detected via firefly luciferin and the expression of Pgc-1α,Bcl-2 and Bax mRNA evaluated by real-time PCR,while the expression of Pgc-1α protein was measured by Western blotting. RESULTS H9c2 cell viability was significantly inhibited by Fuzi decoction 12.5-100 g · L-1(P<0.05,P<0.01). The IC50 value was 47.4669 g · L-1,while the 95%confidence limit was 32.5997-69.1145 g · L-1. After treatment with Fuzi decoction 25 g · L-1 ,the fluorescence intensity of ROS in the normal control group increased from 204±67 to 454±78(P<0.05),that of mitochondrial superoxide increased from 5.4±1.8 to 26.8±8.5 (P<0.01),mitochondrial membrane potential decreased from 1.7±0.5 to 0.8±0.4(P<0.05),the fluores?cence intensity of intracellular Ca2+increased from 7.8±0.8 to 22.1±0.5(P<0.05)while that of mitochon?drial Ca2+decreased from 38.0±4.3 to 9.2±1.6(P<0.01),and intracellular ATP concentration decreased from (10.6 ± 0.4)μmol · g-1 to (5.3 ± 1.1)μmol · g-1 protein (P<0.05). qPCR and Western blotting test results showed that compared with the normal control group ,Pgc-1αand Bcl-2 mRNA relative expression level in Fuzi decoction 25 g·L-1 group was decreased from 1.00±0.10 and 1.00±0.10 to 0.09±0.06(P<0.01)and 0.43±0.06(P<0.01),respectively, while the relative expression of Bax mRNA was increased from 1.00 ± 0.03 to 1.17 ± 0.06 (P<0.05),and the expression of Pgc-1α protein was decreased from 0.906±0.034 to 0.541±0.003(P<0.01). CONCLUSION Fuzi has some mitochondrial toxicity to cardiomy?opathy. This effect arises from the combined action of different mechanisms. Mitochondrial toxicity of myocytes may account for the cardiac toxicity of Fuzi.
