Objective To optimize the volatile oil extraction and inclusion process of Wenweiyang capsules. Methods An orthogonal test was adopted in this study. The extraction technology was optimized for the yield of volatile oil regarding the amount of water loaded, grain size of medicinal material, and decoction time as factors. The inclusion technology was optimized for the inclusion yield and volatile oil inclusion rate using the ratio ofβ-CD:oil, amount of water and grinding time as factors. Results The optimized extraction parameters were as follows:breaking medicinal material through 10 mesh screen, adding 6 fold volume of water and extracting for 5 h. The optimized inclusion progress was grinding at theβ-CD:oil ratio of 81, loading equivalent amount of water and grinding for 30 minutes. The average yield of volatile oil is 1. 72%, the average inclusion rate is 93. 01% and the average volatile oil inclusion rate is 74. 82%. Conclusion The extraction and inclusion technology is simple, reliable, which can effectively retain the volatile oil and provide evidence for the preparation of Wenweiyang capsules.

OBJECTIVETo explore the effect of total flavonoids of Herba Epimedium (FHE) on BMP-2/RunX2/OSX signaling pathway in promoting osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs).

METHODSPassage 3 BMSCs were randomly divided into the control group, the experimental group, and the inhibitor group. BMSCs in the control group were cultured in 0.2% dimethyl sulfoxide + Osteogenuxic Supplement (OS) fluid + DMEM/F12 culture media. BMSCs in the experimental group were intervened by 20 microg/mL FHE. BMSCs in the inhibitor group were intervened by 20 microg/mL FHE and 1 microg/mL NOGGIN recombinant protein. At day 9 alkaline phosphatase (ALP) activity was measured. Calcium nodules were stained by alizarin red staining and the density was observed. The transcription expression of osteogenic differentiation-related proteins (type I collagen, osteocalcin, and osteopontin) and related factors of BMP-2/RunX2/OSX signaling pathway was assayed by RT-PCR.

RESULTSCompared with the control group, ALP activities were enhanced and the density of calcium nodules significantly increased; type I collagen, osteocalcin, and osteopontin expression levels were increased in the experimental group. The expression of osteogenesis-related transcription factor was also increased in the experimental group. Noggin recombinant protein inhibited FHE promoting BMSCs osteogenesis in the inhibitor group. Compared with the experimental group, ALP activity decreased (P < 0.05), the density of calcium nodules was lowered, expression levels of type I collagen, osteocalcin, osteopontin significantly decreased (P < 0.05) in the inhibitor group.

CONCLUSION20 microg/mL FHE promoted osteogenic differentiation process of BMSCs by BMP-2/RunX2/OSX signaling pathway.

OBJECTIVETo systematically review the clinical efficacy of acupuncture on the patients with low back pain (LBP).

METHODSRandomized controlled trials (RCTs) about pure acupuncture therapy versus other treatments in treating LBP were electronically searched in PubMed, CBM, EMbase, The Cochrane Library, CNKI, VIP and Wanfang Data from January 2004 to May 2014. The observed index on the results were the changed scores of VAS, ODI, JOA and RMDQ. Two reviewers independently screened the literatures according to the inclusion and exclusion criteria, as well as the extracted data, and assessed the methodological quality. The results of Meta-analysis was conducted by RevMan 5.2 software.

RESULTSTen RCTs involved 751 patients were finally included. The results of Meta-analysis indicated that the role of pure acupuncture group in improving the VAS score was better than that of the control group, and the combined effect size was RR = -.32, 95% CI (-1.41, -1.22); Z=27.28, P<0.00001; the role of pure acupuncture group in improving the ODI score was better than that of the control group, and the combined effect size was RR = -5.07, 95% CI (-7.50, -2.65); Z=4.10, P<0.0001; the role of pure acupuncture group on improved JOA score was better than that of the control group and the combined effect size was RR=2.83, 95% CI (2.02, 3.63), Z=6.90, P<0.00001. The role of pure acupuncture group in improving the RMDQ score was better than that of the control group, and the combined effect size was RR = -2.80, 95% CI (-3.49, -2.11), Z=7.95, P<0.00001.

CONCLUSIONThe result of meta-analysis demonstrates that pure acupuncture may have a favorable effect on self-reported pain and functional limitations in LBP patients.

OBJECTIVETo explore the theory of "Fei and Dachang being interior-exteriorly related" and the pathogenesis of lung injury by observing changes of inflammatory cytokines and oxygen free radicals in ulcerative colitis (UC) rats.

METHODSTotally 50 healthy male Wistar rats were randomly divided into two groups, the normal control group and the model group, 25 rats in each group. The UC model was established by allergizing colon mucosa combined with TNBS-alcohol (50%) enema. Another 25 rats were recruited as the normal control group. At week 2 and 4 after modeling, the pathomorphological changes of the lung were observed. Furthermore, the contents of tumor necrosis factor alpha (TNF-alpha) and IL-1beta were determined by ELISA. The activities of superoxide dismutase (SOD) and malondialdehyde (MDA) were evaluated with colorimetry.

RESULTSCompared with the normal control group, the pathomorphology of the lung tissue in the model group appeared abnormal at week 2 and 4. Compared with the normal control group, levels of TNF-alpha, IL-1beta, and MDA in the lung tissue significantly increased in the model group (P < 0. 01) and the activities of SOD significantly decreased (P < 0.05, P < 0.01).

CONCLUSIONTNF-alpha, IL-1beta, SOD, and MDA might be common material bases for the large intestine involved in lung disease of UC patients, thus providing a modern scientific basis for the theory of Fei and Dachang being interior-exteriorly related.

Objective To investigate whether the effect of puerarin on right ventricle hypertrophy of pulmonary hypertensive rats induced by chronic hypoxia-hypercapnia was related to new peptide Apelin or its receptor(APJ).Methods Thirty male Sprague-Dawley rats were randomly divided into three groups, they are control group,hypoxia-hypercapnia 4-week model group,and hypoxia-hypercapnia 4-week plus puerarin group.The concentrations of Apelin-36 protein in plasma and homogenate of right ventricular muscle were detected by radioimmunoassay.The mRNA expressions of Apelin and APJ in right ventricu- lar muscle were measured by semi-quantitive reverse transcription polymerase chain reaction(RT-PCR). Results The weight ratio of right ventricle to left ventricle plus septum[RV/(LV+S)] in model group was significantly higher than that in control group(P0.05).The plasma concen- tration of Apelin-36 protein in model group was significantly higher than that in control group(P
