Objective: To search for a rapid and efficient method for the isolation of 3 kinds of isoflavone glucosides from the ethanol extract of Semen Sojae Praeparatum. Methods: The crude isoflavones were extracted by 75% aqueous ethanol after removing the oil by Soxhlet extraction. Then 1300 macroporous resin, water and different concentrations of aqueous ethanol (10%, 20%, 30%, 40%, 50%, 70%, and 95%) were used to separate and elute the crude isoflavones. The fraction eluted by 40% aqueous ethanol was subjected to preparative HPLC analysis. The chromatographic conditions: A YWG C18 (10.0 mm × 200 mm, i. d. 10 μm) column was used; the mobile phase consisted of acetonitrile-water-acetic acid at volume ratio of 25: 75: 1 (V/V/V) and a flow rate of 3.0 ml/min; the injection volume was 750 μl; and the detection wave length was set at 260 nm. Results: Daidzin, glycitin and genistin were rapidly separated with the purities over 99% as determined by external standard HPLC. Conclusion: This technique is simple and suitable for the isolation of daidzin, glycitin and genistin from Semen Sojae Praeparatum.

Objective To investigate the anticancer effect of oxymatrine on cervical cancer cell line (HeLa). Methods MTT assay was used to detect the anti-proliferative effect of oxymatrine.Transwell chamber was used to detect the anti-metastatic effect of oxymatrine.Real-time PCR was used to detect the mRNA levels of MMP-2 and MMP-9.Western blot was used to detect the protein levels of MMP-2,MMP-9,AKT,p-AKT and GADPH. Results We found that application of oxymatrine significantly inhibited the growth of HeLa cells at the concentration above 0.8 mg/mL.We also found that oxymatrine (0.1,0.2 and 0.4 mg/mL)inhibited the invasion of HeLa cells under cytotoxic dose,which was (77.07±20.43)%,(53.95±18.17)% and (20.35±11.20)% of cells that migrated through the matrigel when compared with those of non-oxymatrine treatment group (P<0 .0 5 ). Further research found that oxymatrine (0.1,0.2 and 0.4 mg/mL)could reduce the expression of MMP-2 at the mRNA level,i.e.(82.76±8.71)%,(39.51±12.79)% and (21.53±5.38)% of the expression level when compared with that of non-oxymatrine treatment group (P<0 .0 5 ).The protein expression level of MMP-2 in 0 .4 mg/mL group was (64.69 ±16.52)% of non-oxymatrine treatment group (P<0.05).The phosphorylation level of AKT in 0.4 mg/mL group was (41.27±7.13)% of non-oxymatrine treatment group (P<0.05).Conclusion Oxymatrine can inhibit the invasion of HeLa cells by reducing the expression of MMP-2 via inhibiting the activity of AKT signal pathway.All together,our findings bring new insights into the mechanism of the anticancer effects induced by oxymatrine treatment.

Objective:To investigate the effect of all-trans retinoic acid (ATRA) on the differentiation of marrow stromal stem cells(MSCs)into neurons. Methods: Rat MSCs were expanded as undifferentiated cells in culture for 5-7 passages and pretreated with ATRA for 24 h, then induced by modified neuronal medium (MNM) for 18 h. The control cells were directly cultured in MNM without ATRA pretreatment. Immunocytochemistry was used to detect the expression of nestin, neuron-specific enolase (NSE), neuron-specific nuclear protein (NeuN) and microtuble-associated protein (MAP-2) in the experimental groups and the control cells. The change of cell proliferative cycles and the expression of retinoic acid receptor beta (RAR?) were detected before and after ATRA treatment. Results: 1. The expression of nestin, NSE, NeuN and MAP-2 was much higher than that of the control group. 2. No changes were found in the cell proliferative cycles before and after ATRA treatment. 3. No expression of RAR? was found in MSCs; but positive expression of RAR? was detected afer 24 h of ATRA treatment and it was (20.3?4.2)%. Conclusion: ATRA can activate gene transcription via nuclear receptor RAR? and promote MSCs transdifferentiation into neurons.

Objective To evaluate the intestinal barrier function of the patients by two-sugar absorption test with high performance liquid chromatography (HPLC). Methods Nineteen children with confirmed food hypersensitivity (FH) and 19 normal children were included in this study. The average age was (8.1?1.7) months. After 8-hour fasting, subjects drank test solution (5 g lactulose and 2 g mannitol per 100 ml) at the dose of 2 ml/kg. Five-hour urinary excretion ratio of lactulose/mannitol (L/M) were measured using high performance liquid chromatography (HPLC). The condition of HPLC was as follows: Sugar-PakI column with refractive index detector; Mobile phase: pure deionized water; Flow rate: 0.5 ml/min; temperature of column: 85 ℃. Results HPLC chromatogram of urine sample was stable. The retention time of mannitol and lactulose was 13.86 min and 9.27 min respectively. A significant rise in 5 h urinary L/M excretion ratios was found in children with FH (0.18?0.06) as compared to that of controls (0.05?0.03) (P

Objective:To study the effects of marginal vitamin A deficiency (MVAD) on the hippocampal CA1 long-term potentiation (LTP) in young rats. Methods:Six female rats were divided into two groups at random, three in MVAD group, three in control group. The rats were fed VA deficient diet (400IU VA/kg) and VA sufficient diet (6 500IU VA/kg) respectively since 3 w before coitus. Serum VA was assessed by high performance liquid chromatography (HPLC). The young rats were killed at D49. The hippocampal CA1 LTP was detected by electrophysiological technique and the ultrastructure of synapses was observed by electron microscope. Results:The changes of field excitatory postsynaptic potentials (fEPSP) slope (25.4%?2.01%) in MVAD young rats aged 7 weeks were much lower than that in control group (57.5%?8.63%). The changes of slope of fEPSP induced by MVAD in young rats could be replenished after adding retinoic acid (P0.05). The curvature in synaptic interface of MVAD group was less than that of the MVAD supplemented RA group and the control. Conclusion:MVAD during embryonic and early postnatal period can directly impair the hippocampal CA1 LTP of young rats.

Objective To investigate the effects of early physiotherapy in combination with atorvastatin on the levels of serum brain-derived neurotrophic factor (BDNF) and neurological function in patients with acute ischemic stroke.Methods Fifty patients with acute ischemic stroke were randomly divided into either an atorvastatin group (monotherapy group,n =25) or a early physiotherapy + atorvastatin group (combination treatment group,n =25).All patients received the prescribed drugs according to the diagnosis and treatment guidelines for ischemic stroke.The monotherapy group added atorvastatin calcium (20 mg,1 tablet every night orally).On the basis of the monotherapy group,the combination treatment group also conducted early physical therapy.At 2 and 6 weeks before and after treatment,a double-antboody sandwich enzyme-linked immunosorbent assay was used to detect the serum BDNF levels.The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the degree of neurological deficit.Barthel index (BI) was used to evaluate the activities of daily living.The modified Rankin scale (mRS) was used to assess the degree of disability.Results There was no significant difference in demographics and baseline data between the monotherapy group and the combination treatment group.The scores of NIHSS,BI,and mRS in both groups after treatment were significantly better than those before treatment (all P ＜ 0.001).There were no difference in the scores of NIHSS,BI and mRS at 2 weeks before and after treatment,but at 6 weeks after treatment,the scores of NIHSS (2.40 ± 1.38 vs.3.36 ± 1.73; P =0.035) and mRS (1.40 ± 0.87 vs.1.96 ±0.94; P =0.047) of the combination treatment group were significantly lower than those of the monotherapy group,and the BI scores (92.60 ±7.50 vs.85.20 ± 11.68; P=0.011) were significantly higher than those of the monotherapy group.After treatment,the serum BDNF levels were increased significantly in both groups.There were significant differences among all the time points (all P＜0.001).At 2 weeks after treatment,the serum BDNF levels (3.07 ±0.93 ng/ml vs.2.45 ±0.76 ng/ml; t =2.559,P =0.014) and at 6 weeks after treatment,those (2.90 ± 0.93 ng/ml vs.2.31 ± 0.77 ng/ml; t =2.433,P =0.019) in the combination treatment group were significantly higher than those in the monotherapy group.Spearman correlation analysis showed that the serum BDNF levels were significantly negatively correlated with the scores of NIHSS (r =-0.738,P ＜ 0.001) and mRS (r =-0.654,P ＜ 0.001),but they were significantly positively correlated with the BI scores (r =0.716,P ＜ 0.001).No serious adverse reaction occurred in both groups.Conclusions Early physiotherapy in combination with atorvastatin for the treatment of acute ischemic stroke can more effectively promote the recovery of neurological function,and its mechanism may be associated with the increased serum BDNF levels.

BACKGROUND:There is little attention focused on the effect of isokinetic testing about the variation of angular velocity on pain and muscle strength in the evaluation of curative effect of McConnel taping. OBJECTIVE: To evaluate the changes of quadriceps muscle strength and perceived pain levels in patients with patelofemoral pain syndrome before and after corrective McConnel taping in isokinetic testing. METHODS:A total of 34 patients with patelofemoral pain syndrome were evaluated in isokinetic testing for concentric contraction muscular strength, including the maximum torque, the total work, and the average work in 60 (°)/s and 180 (°)/s angular velocity, before and after the interventions of McConnel taping. The visual analogue scale scores were recorded. RESULTS AND CONCLUSION: The visual analogue scale scores were slightly decreased in angular velocity of 60 (°)/s after obturation when compared to before obturation (P > 0.05), while the scores were significantly decreased in angular velocity of 180 (°)/s (P < 0.05). The maximum torque, the total work, and the average work were slightly increased after obturation, but showed no significant difference in angular velocity of 60 (°)/s (P > 0.05), while significantly increased in 180 (°)/s angular velocity (P < 0.05). McConnel taping significantly improves the curative effect in patients with patelofemoral pain syndrome under low load joint movement.

The Community Herbal Monograph (CHM) is an official document which reflects the scientific opinion of European Medicines Agency (EMA) and plays an important role in technical harmonization of the herbal medicinal products. The role of CHM is very similar with the centralized procedure in the EU level as it represents the technical coordination results of the assessment about safety and efficacy of herbal medicine. The monograph and national procedure, decentralized procedure, and mutual recognition procedure together constitute the coexistence characteristic of centralization and decentralization of the EU medical legislation. The CHM and the traditional herbal medicine registration also constitute the core content of Directive 2004/24/EC in the EU and member state level respectively. And the CHM plays an important role in the registration of traditional herbal medicinal products in the EU member state. However, it has not yet been fully studied by domestic experts and scholars. This paper makes intensive studies on the value of CHM and analyzes the application of monograph in traditional herbal medicine registration. The purpose is to clarify the value and importance of CHM in the registration of traditional Chinese medicine in EU and to provide reference for the Chinese enterprises which are aspiring to open up the EU market.
