OBJECTIVETo observe effects of serum Bushen Huoxue prescription(Chinese characters) on classic Wnt/β-catenin signaling pathways of osteoblasts, and explore mechanism of Bushen Huoxue prescription (Chinese characters) for preventing osteoporosis.

METHODSTwenty health female rats were randomly divided into two groups, including Bushen Huoxue (Chinese characters) group and saline group,10 in each group. Bushen Huoxue (Chinese characters) group and Saline group were gavaged Bushen Huoxue and saline every day for 1 week. Bushenhuoxue containing serum and saline containing serum were got according to methods of serum preparation of drug-containing. The osteoblasts was cultured with neonatal rat skull according to Enzyme Consumer Law, and was identified by Wright-Giemsa staining (R-J) and alkaline phosphatase staining (ALP). The third generation of osteoblasts was divided into three groups, including saline group, normal group,Bushen Huoxue (Chinese characters) group. Each group were added to 15% appropriate medium. ALP activity of osteoblasts and osteoblasts proliferation rate were tested, mineralized nodules were observed, the expression of β-catenin, Runx2, Osx mRNA of osteoblasts were tested by RT-PCR.

RESULTSThere was blue granules in cytoplasm, cell nucleus was flint with 1 to 3 nucleoli showed by R-J staining, morphology of osteoblasts were cultured. ALP staining showed cytoplasm with purple granules, the results showed that the cultured cell was osteoblasts. The content of ALP in Bushen Huoxue (Chinese characters)group was (6.272±0.131) ,appreciation rate was (0.81? 0.172), and could significantly improve differentiation and proliferation activity of osteoblasts compared with Saline group (P< 0.01). There were four different size orange nodules, the Maximun nodule was 1.0 x 1.0 cm in Bushen Huoxue (Chinese characters) group after Alizarin red staining, the results showed Bushen Huoxue (Chinese characters)group could obviously improve mineralization of osteoblasts. The expression of mRNA of β-catenin, Runx2 and Osx in Bushen Huoxue (Chinese characters)group were (1.782±0.944), (1.935±0.994) and (1.610±0.811) by RT-PCR,it was significantly increased compared with saline group (P<0.01), but there was no difference between Bushen Huoxue (Chinese characters)group and normal group (P>0.05).

CONCLUSIONBushen Huoxue (Chinese characters)group could obviously promote differentiation, proliferation and mineralization of osteoblasts through activation of Wnt, β-catenin signaling pathway. It suggested that the mechanism of action of Bushen Huoxue (O'f f Il.t)particle clould prevent osteoporosis through the activation of Wnt, β-catenin signaling pathway.

To explore the effect of different processing methods and conditions of coumarin and volatile compounds in Angelica Dahuricae Radix and their change regularity, in order to optimize and establish appropriate drying methods and conditions. After being cleaned, fresh Angelica Dahuricae Radix herbs were baked, sun-dried, shade-dried, sun-dried after sulfur-fumigation, dried by quick-lime embedding, freeze-dried, microwave-dried. Finally, 24 groups of samples were obtained after being mashed and passing through the 60-mesh screen. The HPLC-PDA method was adopted to simultaneously determine the content of coumarin compounds. The GC-MS method was used to determine the content of volatile compounds. The principal component analysis (PCA) was made on the standardized analysis results for the 24 groups of samples processed with different drying methods. According to the PCA results, the comprehensive scores of coumarin and volatile compounds in Angelica Dahuricae Radix herbs processed with different methods in the order from high to low were that unpeeled and dried by quicklime embedding > unpeeled and dried with hot-air at 100 degrees C > unpeeled and dried with hot-air at 40 degrees C > peeled and infrared-dried > peeled and dried with hot-air at 60 degrees C > peeled and dried with hot-air at 40 degrees C > peeled and sun-dried > peeled and dried with hot-air at 60 degrees C > peeled and dried with hot-air at 100 degrees C > peeled and microwave-dried > peeled and dried with hot-air at 80 degrees C > unpeeled and sun-dried > unpeeled and dried with sulfur-fumigation > peeled and dried with sulfur-fumigation > unpeeled and dried with hot-air at 120 degrees C > unpeeled and freeze-dried > unpeeled and infrared-dried > peeled and dried with hot-air at 120 degrees C > peeled and freeze-dried > peeled and dried by quicklime embedding > unpeeled and dried with hot-air at 80 degrees C > peeled and shade-dried > unpeeled and shade-dried > unpeeled and microwave-dried. According to the findings, different drying processing methods have certain impacts on the content coumarin and volatile compounds in Angelica Dahuricae Radix herbs. The traditional method of drying by quicklime embedding is recommended as the optimum origin processing method of Angelica Dahuricae Radix, which is followed by the method for being peeled and dried with hot-air at 100 degrees C.

OBJECTIVETo compare the difference in clinical efficacy on children attention deficit hyperactivity disorder (ADHD) between the combined therapy of scalp acupuncture and EGG biofeedback and the simple EEG biofeedback therapy so as to search the better therapeutic method for ADHD.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the simple EEG biofeedback therapy was adopted. In the observation group, on the basis of biofeedback therapy, scalp acupuncture was added and applied to Dingzhongxian (MS 5), Dingpangyixian (MS 8), Baihui (GV 20), Sishencong (EX-HN 1), etc. The ten treatments made one session. After four sessions of treatment, FIQ value in Wechsler intelligence scale, CIH score in Conners children behavior questionnaire, the ratio of 0 wave and p wave in EEG, FRCQ and FAQ in the integrated visual and auditory continuous performance test (IVA-CPT) and clinical comprehensive efficacy were observed before and after treatment in the two groups separately.

RESULTSThree cases were dropped out in the observation group and 2 cases were out in the control group. In the two groups, FIQ, FRCQ and FAQ were all increased after treatment (P < 0.01, P < 0.05); the increases in the observation group were much more significant than those in the control group after treatment (all P < 0.05). In the two groups, CIH score and the ratio of 0 wave and p wave were all reduced after treatment (P < 0.01, P < 0.05); the reduction in the observation group were much more apparent as compared with those in the control group (both P< 0.05). The total effective rate was 91.5% (43/47) in the observation group and better than 83. 3% (40/48, P < 0.01) in the control group.

CONCLUSIONThe combined therapy of scalp acupuncture and EEG biofeedback achieves the superior efficacy on children ADHD as compared with the simple biofeedback therapy. This combined therapy rapidly relieves the essential symptoms of ADHD and improves EEG waveform in children patients. Importantly, this therapy obtains and consolidates the significant efficacy.

AIM:To investigate the effect of oleuropein on interleukin-1β( IL-1β)-induced SD rat articular chondrocytes .METHODS:The SD rat articular chondrocytes were isolated by 2 step enzyme digestions .The chondrocytes were cultured in vitro.Inverted microscopic observation was performed during the culture .Alcian blue staining and type II collagen immunohistochemical staining were used to identify the chondrocytes .The effects of oleuropein on the viability of chondrocytes were determined by CCK-8 assay.The cells in 3rd passage were pretreated with oleuropein at 10, 50 or 100 μmol/L and subsequently stimulated with IL-1βat 10 μg/L for 24 h.Production of prostaglandin E 2 ( PGE2 ) and ni-tric oxide (NO) were evaluated by the Griess reaction and an enzyme linked immunosorbent assay (ELISA).The mRNA expression of matrix metalloproteinase ( MMP)-1 and MMP-13 was measured by real-time PCR.The protein levels of in-ducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and nuclear factor-kappa B (NF-κB) were detected by Western blotting .RESULTS:The cell viability of chondrocytes was not significantly impaired by treating with oleuropein at concentration of 10, 50 or 100μmol/L for 24 h compared with control group .Pretreatment with oleuropein significantly in-hibited the production of PGE 2 and NO induced by IL-1β.Oleuropein also significantly decreased the IL-1β-stimulated MMP-1 and MMP-13 mRNA expression in articular chondrocytes .Pretreatment with oleuropein inhibited the IL-1β-media-ted activation of NF-κB by suppressing the degradation of its inhibitory protein IκBαin the cytoplasm .CONCLUSION:Oleuropein inhibits IL-1β-induced inflammatory gene expression by suppressing NF-κB activation at the transcriptional le-vel, suggesting a new mechanism for the anti-inflammatory effects of oleuropein as a novel agent on treating with osteoarthri-tis.

Objective To explore the level of hypersensitive C-reactive protein (hs-CRP)in the patients with acute ischemic stroke(AIS)and its clinical significance.Methods The BNⅡhighly sensitive automatical scattering turbidimetric immunity analy-zer was adopted to detect serum hs-CRP level in 64 cases of AIS and contemporaneous 32 individuals with healthy physical examina-tion as the control group.The data of AIS cases were retrospectively analyzed.Results The positive rate of hs-CRP was 53.3% in the AIS group and 9% in the control group with statistically significant difference between them(P <0.05);the overall levels of hs-CRP in the AIS group was in inconformity to the normal distribution,the median was 4.26mg/L,which in the control group was (0.99 ± 0.72 )mg/L,there was statistically significant difference between them (P < 0.05 );the average level of hs-CRP was (5.03±1.51)mg/L in the AIS male group and (2.79 ± 1.09)mg/L in the AIS female group,the difference between them had sta-tostical significance(P <0.05).Conclusion The serum hs-CRP level in the AIS patients is higher than that in the healthy crowd with statistical difference(P <0.05).The age and sex may be the causes influencing serum level of hs-CRP in the AIS patients.The average age in the AIS patients with positive hs-CRP is higher than that with negative hs-CRP.Middle-aged and elderly people with hypertension and diabetes are much more dangerous than healthy people in getting AIS.

BACKGROUND:Many in vivo and in vitro experiments indicate that hypoxic co-cultures promote stem cells differentiate into chondrocytes.
OBJECTIVE:To evaluate the influence of hypoxia on the chondrogenic differentiation of three-dimensional co-cultured adipose-derived stem cells and articular chondrocytes.
METHODS:Adipose-derived stem cells and articular chondrocytes were mixed at the ratio of 3:1, then the mixed cells were seeded onto poly(lactic-co-glycolic acid)-gelatin scaffold at the ultimate concentration of 5.0×1010/L. The cells were cultured in normoxia (20%O 2 ) and hypoxic (5%O 2 ) conditions for 6 weeks. After culture, hematoxylin and eosin staining was performed for histological structure analysis, and alcian blue staining was used to evaluate glycosaminoglycan synthesis. Type II col agen expression was detected by immunohistochemistry staining. The content of DNA, glycosaminoglycan and hydroxyproline in the scaffold-cellcomplex was measured.
RESULTS AND CONCLUSION:In the hypoxia group, hematoxylin-eosin staining showed the formation of massive cells and extracellular matrix;alcian blue staining showed massive glycosaminoglycan formation;immunohistochemistry staining detected strongly positive expression of col agen type II, the content of DNA, glycosaminoglycan and hydroxyproline was higher than the normoxia group. Hypoxia promotes in vitro chondrogenic differentiation of co-cultured adipose-derived stem cells and articular chondrocytes. .

Objective: To observe the clinical efficacy of spleen-invigorating and qi-benefiting pediatric massage (tuina) for treating recurrent respiratory tract infection in children with cerebral palsy due to qi deficiency of spleen and lung. Methods: A total of 70 children with cerebral palsy who suffered from recurrent respiratory tract infection due to qi deficiency of spleen and lung were randomized into an observation group and a control group by the random number table method, with 35 cases in each group. Both groups were treated with conventional rehabilitation training, while the observation group was given additional spleen-invigorating and qi-benefiting pediatric massage, and the control group additionally took oral Yu Ping Feng granule. The clinical efficacy was evaluated by the total effective rate, traditional Chinese medicine (TCM) symptom score, and serum levels of immunoglobulin (Ig) A, IgM and IgG. Results: The difference in total effective rate between the two groups after treatment was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased to varying degrees than those before treatment, and the intra-group differences were statistically significant (all P<0.01); the differences in the scores of various TCM symptoms between the two groups were statistically significant (all P<0.05). After treatment, the levels of IgA, IgM and IgG of the children in both groups increased to varying degrees, and the intra-group differences were statistically significant (all P<0.05). The between-group differences in the IgA, IgM and IgG levels after treatment were statistically significant (all P<0.05). Conclusion: Spleen-invigorating and qi-benefiting pediatric massage can effectively treat recurrent respiratory tract infection due to qi deficiency of spleen and lung in children with cerebral palsy, relieve the clinical symptoms and improve immune function, and thus is worthy of clinical promotion and application.
