1. Three strategies for hemostasis at femoral artery access site: A comparison of safety and efficacy
Academic Journal of Second Military Medical University 2006;27(6):645-648
Objective: To assess the safety and efficacy of the standard manual compression and 2 arterial puncture closing devices, Angioseal and Perclose, for hemostasis at the femoral artery access site in patients undergoing coronary angiography (CAG) or percutaneous coronary interventions (PCI). Methods: Totally 366 patients undergoing coronary angiography or PCI were assigned to receive either Angioseal (n=128), Perclose (n=110) or standard manual compression (n=128). The efficacy endpoint (immediate hemostasis, successful hemostasis rate, operating time, time of leg immobilization and time to hemostasis) and safety endpoint (vasovagal reflex, major complications, local complications, hematocrit drop, etc.) were evaluated. Risk factors (gender, age, body mass index, comorbid conditions, antiplatelet agents, and anticoagulant agents, etc.) were also analyzed. Results: The successful hemostasis rates were similar be tween Angioseal group and Perclose group, but the rate of immediate hemostasis of Angioseal group was higher than that of Perclose group (P<0.01). Time of leg immobilization and time to hemostasis in Angioseal group and Perclose group was shorter than those of manual compression group(P<0.01). Both vasovagal reflex (9.3%) and major complications (3.1%) were only noticed in manual compression group. The rates of local complications in manual compression group and Angioseal group were both lower than that of Perclose group(P<0.01). Post-procedure unfractionated heparin was associated with increased risk of hematoma (OR=4.382, P<0.05), post-procedure clopidogrel (OR=3.549, P<0.01) and interventional procedures (OR=6.584, P<0.05) were associated with increased risk of blood oozing, and female gender was associated with a reduced risk of blood oozing (OR=0.132, P<0.05). The successful hemostasis rates were lower in the elderly and those receiving PCI. Post-procedure unfractionated heparin and low molecular weight heparin was associated with longer hemostasis time. Conclusion: Perclose and An gioseal can be an alternative of standard manual compression for hemostasis of the femoral artery access site. Angioseal may be better than Perclose regarding the immediate hemostasis and local complications.

Objective:To identify potentially pleiotropic genes for lean body mass ( LBM ) and age at menarche ( AAM).Methods:The discovery sample consisted of 1 692 unrelated female subjects of European ancestry.The replication sample consisted of 801 unrelated female subjects of Han Chinese ancestry.A total of 909,622 single nucleotide polymorphisms (SNPs) were genotyped in both samples with the Affymetrix genome-wide genotyping array SNP 6.0.Bivariate genome-wide association analyses were then performed to the appendicular LBM and AAM.Results: Two SNP rs1860547 and rs11030746 identified by the bivariate GWAS were significant at the genome-wide significance (GWS) level;their P-values were <0.05 after replications.In the upstream of rs1860547, two genes KCNA1 and KCNA5 were found to be important for both LBM and AAM.In the downstream of rs11030746, one gene KCNA4 was found.Univariate GWAS also identified both SNPs to be significant at the GWS level; their P-values were <0.05 after replications.In the upstream of rs1860547 , two genes KCNA1 and KCNA5 are found to be important for LBM.In the downstream of rs11030746 , one gene KCNA4 was found.Conclusion:KCNA1, KCNA4 and KCNA5 are likely to be pleiotropic genes closely related to both LBM and AAM in European females.

K. There was no significant difference in the yield among the treatments of N+K, CK, P, N+P, and N, but the results of these five treatments were significantly higher than that of P+K and K. In addition, cichoric acid content did not considerably changed after treatment of various fertilizer combinations. For the second harvest date the yield of N, N+K, P, and N+P were 47.7%, 35.4%, 33.8%, and 12.3% higher respectively than that of CK, the yield of N+P+K, P+K, and K were 7.7%, 10.8%, and 28.5% lower respectively than that of CK. There was significant difference in the yield between the treatment of N and CK, the yield of K was significantly lower than that of CK. Conclusion The results indicate that cichoric acid content is not significantly affected by the treatment of various fertilizer combinations and the yield is strongly influenced by N fertilizer, weakly by P fertilizer, on the contrary the application of potassium chloride results in a decrease in yield.
5. Study on DNA protection of polysaccharide and flavonoids in Artemisia annua L. from different areas with fluorescence probe
Chinese Pharmaceutical Journal 2012;47(8):581-584
OBJECTIVE: To investigate the DNA protection of polysaccharide and flavonoids in 14 kinds of Chinese herbs of Artemisia annua L. from different growing places such as Hunan, Chongqing, Beijing etc. METHODS: The fluorescence integration intensity of DNA, EB and extracts containing polysaccharide and flavonoids from 14 kinds of Artemisia annua L. were determined with EB as a sensitive fluorescence probe. Constant D was used to directly denote the degree of interaction between the drug molecules with DNA. According to the size of D, the protective action of polysaccharide and flavonoids on DNA was discussed. RESULTS: The order of interaction degree of polysaccharide in extracts with DNA was as follows; Hunan Huaihua > Beijing > Shanxi Yushe > Hunan (Xinzhou cultivation) > Shanxi Xinzhou cultivation in room > Chongqing (Xinzhou cultivation) > Hebei Fuping > Shanxi Dingxiang Nanzhuang > Chongqing > Shanxi Xinzhou Luye > Shanxi Yuxian > Shanxi Grey artemisia (Yangqu) ; The order of interaction of flavonoids in extracts with DNA through determination was as follows; Shanxi Xinzhou Luye > Hunan(Xinzhou cultivation) > Shanxi Xinzhou cultivation in room > Chongqing(Xinzhou cultivation) > Wild Artemisia(Shanxi Xinzhou) > Grey artemisia (Shanxi Yangqu) > Shanxi Dingxiang Nanzhuang > Chongqing > Hebei Fuping > Beijing > Shanxi Yushe > Iron rod Artemisia(Shanxi Xinzhou) > Shanxi Yuxian > Hunan Huaihua. The interaction of artemisia polysaccharide and flavonoids with DNA showed a definite dose-effect relationship. CONCLUSION: The extracts of Artemisia annua L. could interact with DNA, but the degree of interaction was different. The bigger the D was, the stronger the interaction was.

Objective To compare tbe efficacy of conventional therapy,psychotherapy,serotonin reuptake in- hibitor,and psychotherapy combined with serotonin reuptake inhibitor in rehabilitating nerve function in the treatment of post-stroke depression.Methods One hundred and twenty patients with post-stroke depression were divided into a control group(A),a group treated with serotonin reuptake inhibitor (B),a psychotherapy group (C) and a group in which psychotherapy was combined with serotonin rcuptake inhibitor(D).These groups were graded with the SDS for the degree of their depression and with the MESSS for their muscle strength before andafter treatment.Results The anti-depression therapies showed significantly different effects in improving depression.After eight weeks,group D showed significantly less depression than the others.However,muscle strength did not show statistically significant differences until twelve weeks,when group D again showed better progress than the others.Conclusion Psychothera- py combined with serotonin reuptake inhibitor can promote the rehabilitation of nervous function-after stroke.

Protein fulfilling the their roles, one of important ways is through protein-protein interaction. In functional genomic era, identifying all of protein-protein interaction in proteome and mapping the protein interactions that have been attracting many scientists' attention , of which large-scale yeast two-hybrid system is one strategy of most widely used. In recent two years, ambitious projects have launched to examine all of the protein-protein interaction in Saccharomyces cer-evisiae using large-scale yeast two-hybrid system. Nevertheless, huge protein network is larger than that we predict and single yeast two-hybrid system cannot solve all the problems, which need be complemented by other wags.
