Objective: To obtain the bFGF mimic peptide binding to FGFR via phage display, and to provide the base for developing peptide agonist of bFGF. Methods: Using Balb/c 3T3 cells as the target cells and COS-7 cells as the subtractive panning, the phage display heptapeptide library was biopanned for 4 rounds to obtain the single phage clones. The affinity and the specificity of the clones were assessed by ELISA. DNA sequencing was applied to further analyze the positive clones. Results: Twelve positive clones were selected from the enriched phages. A group of hydrophobic peptides containing a conserved motif, PR, was identified. Conclusion: Two bFGF mimic heptapeptides binding to FGFR were selected, which may be used as the candidates for bFGF agonist.

OBJECTIVETo observe the efficacy on primary osteoporosis treated with spreading moxibustion for warming yang and activating blood circulation so as to provide the effective clinical therapeutic methods for osteoporosis.

METHODSSixty cases of primary osteoporosis were randomized into a spreading moxibustion group (30 cases) and a calcium tablet group (30 cases). In the calcium tablet group, caltrate was prescribed for oral administration, 600 mg per day. In the spreading moxibustion group, on the basis of the treatment as the calcium tablet group, the spreading moxibustion was applied at Dazhui (GV 14) to Yaoshu (GV 2) for warming yang and activating blood circulation. The duration of treatment was 12 weeks. Visual analogue scale (VAS) score, TCM clinical symptom score and bone mineral density (BMD) were observed and compared before and after treatment in the patients between the two groups.

RESULTSVAS scores were reduced apparently after treatment in the two groups (both P < 0.01) and the results in the spreading moxibustion group were obviously superior to that in the calcium tablet group (2.36 +/- 0.43 vs 4.52 +/- 0.35, P < 0.01). BMD were all increased in the two groups (P < 0.05, P < 0.01) and the results in the spreading moxibustion group were superior to those in the calcium tablet group (both P < 0.05). The total clinical effective rate was 86.67% (26/30) in the spreading moxibustion group, apparently better than 63.33% (19/30) in the calcium tablet group (P < 0.05). TCM clinical symptom scores after treatment were all reduced apparently in the two groups (both P < 0.01), and the result in the spreading moxibustion group was obviously superior to that in the calcium tablet group (4.72 +/- 1.90 vs 6.82 +/- 2.30, P < 0.01). The total effective rate of TCM symptoms was 93.33% (28/30) in the spreading moxibustion group, apparently better than 70.00% (21/30) in the calcium tablet group (P < 0.05).

CONCLUSIONThe combined therapy of spreading moxibustion for warming yang and activating blood circulation and the oral administration of caltrate apparently relieves pain and TCM clinical symptoms, improves BMD in the patients of osteoporosis and achieves definite clinical efficacy in the patients of osteoporosis.

To improve the efficiency of halophilic actinobacteria screening and carry out the rapid selection of targeted strains, we tested 34 strains of Streptomonospora by PCR-single strand conformation polymorphism analysis (PCR-SSCP) based on genus-specific primers for the PCR identification. This approach employs PCR with two pairs of primers located in the 16S rRNA sequence flanking two variable region, then build clustering tree according as SSCP data. Synchronously, we sequenced all the 16S rRNA partial sequences for these strains to verify them. The results showed that the PCR-SSCP analysis was an efficient, easy-to-handle and economic method for rapid selection of halophilic actinobacteria resources.

The contents of schisandrol A, schisandrol B, schisantherin A, schisandrin A , schisandrin B, schisandrin C in Schisandrae Chinensis Fructus (SCF) were determined simultaneously by HPLC. Collect 100-seed weight, color, pulp content, longitude and latitude of SCF of different batches were collected. SIMCA-P and SPSS were applied to make PLS-DA analysis of 24 batches of SCF and correlation analysis of relevant parameters. According to the 13 parameters, SCF from three different places of origin could be distinguished effectively. It was found that the content of chemical component of SCF increased with latitude and longitude first, and then decrease. The results provide some theoretical basis for study of SCF genuineness and traditional method of identifying just from experience.

Yinchenwuling powder is a classic prescription of hygrosisdissipating and choloplania,which has been commonly used till now,with the further research and development of Yinchenwuling powder,It is not only nourish the liver and gallbladder,but also reducing blood lipid and anti-atherosclerosis,and has good effected in antiallergic,antiinflammation,analgesia and other aspects.Often used in jaundice,hepatitis,hyperlipidemia,gouty Arthritis,etc..Now we discussed the pharmacological action and clinical application of Yinchenwuling powder.

To produce antibodies capable of neutralizing botulinum neurotoxin type B(BoNT/B),We cloned the carboxy-terminal end of Hc containing the major determinants responsible for specific toxin,induced and purifed.The heavy-chain and kappa light-chain variable region gene repertoire of immunoglobulin were amplified individually from the spleen cell mRNA by RT-PCR and joined as a single-chain Fv(scFv)DNA fragment.These fragment were cloned into the phagemid pCANTAB5E and the phage display library was constructed.Results showed that the high affinity scFv was obtained after 4 rounds of panning,with its DNA sequence conforming to that of mouse antibody.

Objective:To observe the clinical efficacy of body acupuncture combined with FANG's scalp acupuncture in treating limb dysfunction in the remission stage of stroke and explore the mechanism. Methods:Sixty patients in the remission stage of stroke with limb dysfunction were divided into a control group and a treatment group using the random number table method,with 30 cases in each group.The control group was treated with ordinary acupuncture based on the conventional rehabilitation treatment,and the treatment group was additionally offered FANG's scalp acupuncture.The interventions were conducted once daily with 10 sessions as 1 course.The Fugl-Meyer assessment(FMA)and Barthel index(BI)scores and serum malondialdehyde(MDA)and superoxide dismutase(SOD)levels were compared after 2 treatment courses,and the clinical efficacy was evaluated. Results:After treatment,the FMA and BI scores increased in both groups(P<0.05)and were higher in the treatment group than in the control group(P<0.05).Both groups showed a decreased MDA level and an increased SOD level after the intervention,all showing statistical significance(P<0.05);there were significant differences between the two groups(P<0.05). Conclusion:Based on the conventional rehabilitation treatment,ordinary acupuncture used alone or in combination with FANG's scalp acupuncture can lower the oxidative stress level and improve limb function in treating limb dysfunction in the remission stage of stroke;body acupuncture plus FANG's scalp acupuncture can produce better results.

OBJECTIVETo study the protective effect of formula of removing both phlegm and blood stasis (TYTZ) on myocardial tissues of Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome.

METHODTotally 36 Chinese mini-swine were randomly divided to six groups: the normal control group, the model group, the Danlou tablet group, and TYTZ groups with doses of 2.0, 1.0, 0.5 g x kg(-1), with six in each group. Except for the normal control group, all of other groups were fed with high-fat diet for 2 weeks. Interventional balloons are adopted to injure their left anterior descending artery endothelium. After the operation, they were fed with high-fat diet for 8 weeks to prepare the coronary heart disease model of phlegm-stasis cementation syndrome in Chinese mini-swine. After the operation, they were administered with drugs for 8 weeks. The SOD activity and MDA content of each group were observed at the 0th week (before the experiment), the 2nd week after the high-fat diet (before the operation or drug administration) , the 6th week after the high-fat diet (4 weeks after the drug administration) and the 10th week after the high-fat diet (8 weeks after the drug administration). Meanwhile, the myocardial enzymogram test and the HE staining pathological observation were performed at the end of the experiment. The changes in the myocardial cell ultra-structure were observed under transmission electron microscope.

RESULTCompared with the normal control group, the model group showed significant decrease in serum SOD activity and notable increase in MDA content from the 2nd week to the end of experiment (P < 0.05 and P < 0.01). In the 10th week, the CK, LDH and CK-MB levels in serum also significantly increased in the model group (P < 0.05 and P < 0.01), with obvious structural abnormality in myocardial tissue pathologic morphology and ultra-structure. Compared with the model group, TYTZ groups showed specific increase in serum SOD activity and oblivious decrease in the MDA level (P < 0.05 or P < 0.01). Meanwhile, TYTZ could significantly decrease serum CK and LDH levels in the model group (P < 0.05 or P < 0.01), attenuate the ischemia injury of myocardial tissue, and improve the ultra-structure of cardiomyocytes.

CONCLUSIONTYTZ shows an obvious protective effect on the myocardial injury in Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome. Its mechanism is related to the resistance against free radical oxidation injury and the inhibition of the lipid per-oxidation.
