Objective To investigate the vascular effect of hydroxyl-safflor yellow A(HSYA) on rat thoracic aorta and its underlying mechanism. Methods The tension of isolated thoracic aorta rings of rats perfused with different concentrations of HSYA(1?10-6-1?10-4 mol/L) was measured using organ bath technique.The effects of HSYA on the vasocontraction induced by cumulative phenylephrine(PE)(1?10-6-1?10-4 mol/L),KCl(6?10-2 mol/L) and CaCl2(1?10-5-3?10-3 mol/L) were recorded respectively. Results HSYAcaused a concentration-dependent anti-contraction effects by KCl or PE in endothelium-intact and endothelium-denuded aortic rings.HSYA inhibited the CaCl2-induced contraction and downward shifted concentration-response curve of aortic rings.HSYA+HP resulted in more significant anti-contraction effect than single use of HSYA(P0.05).There were significant differences in anti-contraction effect between HSYA+RR and RR or HSYA(P

To study the chemical components and the antifungal activity of extraction from conidia of Trichoderma viride LTR-2.The extraction were obtained by distilling with Methylene dichloride from conidia of Trichoderma viride LTR-2 cultured on wheat bran solid matrix.Antifungal activity were determined by mycelium growth method.The chemical components of the extraction were analysed by GC-MS,the relative components in the extraction were determined by area normalization.The extraction not only have broad-spectrum control,showed antibiosis against eleven different plant fungal pathogens in PDA dish,such as Rhizoctonia solani,Alternaria brassica,Verticillium dahliae,Macrophoma kawatsukai,Fusarium moniliforme,Botrytis cinerea,Rhizoctonia cerealis,Fusarium oxysporum f.sp.vasinfectum,Bipolaris sorokinana,Fusarium graminearum,Alternaria.mali,but also have high inhibitory effect,and had 89.3% suppressive rate to Rhizoctonia cerealis.About sixty components were separated and identified by GC-MS,majority components were Hydrocarbon,the number of the Hydrocarbon were fourty-three kinds.Ergosterol was the major chemical components of the extract,and has 41.90% content.Other components comprised:Ketone,Organic acid,Alcohol,Ene,et al.Conclusion:The extraction from conidia of Trichoderma viride LTR-2 have antifungal activity.The extration comprised 2H-Pyran-2-one,5,6-dihydro-6-pentyl,it has 2.35% content.reference others literature,2H-Pyran-2-one,5,6-dihydro-6-pentyl may be the suppressive component of the extration.

OBJECTIVETo explore the clinical effects of locking plates in the treatment of intertrochanteric hip fractures.

METHODSFrom February 2006 to December 2008,108 patients with intertrochanteric hip fractures treated with locking plate and DHS were retrospective analyzed. Fifty-one patients were treated with locking plates, including 23 males and 28 females, aged 45 to 86 years old (averaged 66.0 years old); and fifty-seven patients were treated with DHS, including 26 males and 31 females,aged 43 to 81 years old (averaged 64.1 years old). The outcome measures collected for statistical analysis on the following aspects: operative time, blood loss, drainage, healing time, complications and Harris scores.

RESULTSOne hundred and eight patients were followed up ranging from 8 to 24 months (averaged 12.5 months). In locking plate group, the operative time was (87 +/- 14) minutes; blood loss was (367 +/- 213) ml; drainage was (63 +/- 14) ml; healing time was (11.9 +/- 3.4) weeks; 7 patients had complications; and the Harriss score was (85 +/- 6). While in DHS group, the operative time was (115 +/- 23) minutes; blood loss was (582 +/- 243) ml; drainage was (98 +/- 16) ml; healing time was (12.4 +/- 2.5) weeks; 9 patients had complications; and the Harriss score was (84 +/- 8). There were no significant differences in the healing time, complications and Harris scores between two groups (P > 0.05),but there were significant differences in the operative time,blood loss, drainage between two groups (P < 0.05). Comparing with DHS group, the locking plate group was of shorter operative time, fewer blood loss and drainage.

CONCLUSIONProximal femoral locking plate is simple, minimally invasive,stable fixation with fewer complications, and is an effective method for intertrochanteric hip fractures.

OBJECTIVETo investigate the splice variants of the calpain 3 gene existing in human skeletal muscle tissue and white blood cells, and to explore the feasibility of gene diagnosis using CAPN3 mRNA extracted from peripheral leukocytes.

METHODSTotal RNA was extracted from peripheral blood and skeletal muscle tissue in healthy individuals. CAPN3 cDNAs were determined by reverse transcriptase polymerase chain reaction and DNA sequencing. CAPN3 cDNAs from peripheral leukocytes were compared with sequences obtained from skeletal muscle tissue.

RESULTSRT-PCR and DNA sequencing showed that the CAPN3 cDNAs comprised 24 exons in human skeletal muscle tissue, while the number of exons was 23 in white blood cells. Exon 15 was spliced out in human white blood cells.

CONCLUSIONSplice variants exist in human skeletal muscle tissue and white blood cells. Gene diagnosis may omit the mutations of exon 15 using mRNA extracted from peripheral leukocytes. These findings suggest that mutation analysis of the CAPN3 cDNA should use skeletal muscle tissue as materials instead of peripheral blood.

OBJECTIVETo probe into a better therapeutic method for functional constipation.

METHODSNinety-five cases of functional constipation were randomly divided into deep puncture at ST 25 group (48 cases), shallow puncture at ST 25 group (24 cases) and medication group (23 cases). In deep puncture at ST 25 group, Tianshu (ST 25) was punctured deeply to the peritoneum, with electric stimulation. In shallow puncture at ST 25 group, Tianshu (ST 25) was punctured shallowly, 5 mm beneath the skin, with electric stimulation. In medication group, Duphalac was administered orally. These cases were treated continuously for 4 weeks in 3 groups and followed up for 6 months. It was to observe the numbers of person who had defecation 4 times a week, difference in weekly defecation frequency and the difference in the Cleveland Clinic Score (CCS).

RESULTSIn deep puncture at ST 25 group, the frequency of weekly defecation and the numbers of person who had defecation 4 times a week increased and CCS decreased, which were similar to the efficacy in shallow puncture at ST 25 group (all P > 0.05). But the efficacy of both ST 25 groups was superior to that in medication group (both P < 0.05). In comparison, the deep puncture at ST 25 group acted more quickly than either shallow puncture at ST 25 group or medication group and its efficacy remained much longer.

CONCLUSIONThe deep puncture at ST 25 with electric stimulation presents similar efficacy on functional constipation as shallow puncture at ST 25, but it acts more quickly than shallow puncture at ST 25, both of them are more advantageous than medication and the long-term efficacy is better.
