Objective To investigate the protective effects of felodipine on mRNA levels of endothelial nitricoxide synthase (eNOS) and inducible nitricoxide synthase (iNOS) as well as the level of nitrogen monoxidum (NO) from human umbilical vein endothelial cells (HUVECs) injuryed by oxidized low density lipoprotein (ox-LDL). Methods Isolated HUVECs were divided into blank control group,ox-LDL injury group treated with ox-LDL of different concentrations (6,12.5 and 25 mg/L),and intervention group of felodipine (0.1,1.0 and 10 ?mol/L)+ox-LDL (25 mg/L). Then eNOS and iNOS expressions were measured by real time-polymerase chain reaction and the level of NO in the supernatants of the cultures was assayed by nitrate reductase method. Results The mRNA expressions of eNOS and iNOS in HUVECs and NO level in the supernatants during treatment with different ox-LDL concentrations were higher than those in control group. However,felodipine significantly down-regulated the expression of iNOS in HUVECs injured by ox-LDL and inceased NO generation. Conclusion Felodipine has protective effects on endothelial cells. The mechanism may be related to its lowering the mRNA expression of iNOS induced by low ox-LDL concentration and increasing NO production.

Objective To investigate the protective effect of felodipine on reactive oxygen species (ROS) generation,mRNA level of inflammatory factors such as intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1),in human umbilical vein endothelial cells (HUVECs) injured by oxidized low-density lipoprotein (ox-LDL) so as to explore felodipine's anti-atherosclerosis mechanism independent of its anti-hypertensive effect. Methods Isolated HUVECs were treated with ox-LDL at different concentrations (6,12.5 and 25 mg/L) for 24 hours so that the optimal concentration and time of ox-LDL treatment were selected. Then the cells were incubated with ox-LDL and treated with felodipine at different concentrations (0.1,1 and 10 ?mol/L). Intracellular ROS level was determined by flow cytometry (FCM). Expressions of inflammatory factors ICAM-1 and VCAM-1 were measured by real time-polymerase chain reaction (real time-PCR). Results ROS generation was increased in HUVECs after treatment with different concentrations (6,12.5 and 25 mg/L) of ox-LDL for 24 hours and there was a significant difference at 25 mg/L ox-LDL (P

Functional constipation (FC) is a common functional bowel disorder disease that affects life quality of a large number of people. This study aimed to explore the impact of different intensities of electro-acupuncture (EA) treatment for FC patients. Totally, 111 patients with FC meeting the Rome III criteria were randomly assigned to different intensities of EA groups (low and high intensity of EA groups) and medicine-controlled (MC) group. In EA groups, patients were treated with EA at quchi (LI11) and shangjuxu (ST37) bilaterally for 4 weeks, 5 times/week in the first 2 weeks, and 3 times/week in the last 2 weeks. In MC group, 5 mg mosapride citrate was administered orally 3 times/day for 4 weeks. Spontaneous bowel movement frequency each day was recorded using a constipation diary. Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to assess the patients' psychological state. Cortisol (CORT), substance P (SP), and vasoactive intestinal polypeptide (VIP) were evaluated at baseline and at the end of 4 weeks after treatment. As compared with the baseline, there was statistically significant increase in stool frequency every week (P<0.01), but there was no statistically significant difference among the three groups. As compared with the baseline, after 4 weeks of EA therapy, the scores of SDS and serum levels of CORT were decreased significantly in low intensity of EA group (P<0.01), and the serum levels of SP and VIP were increased significantly (P<0.05); the scores of SAS and SDS and serum levels of CORT were decreased significantly in high intensity of EA group (P<0.05), and the serum levels of SP and VIP were increased significantly (P<0.05); the serum levels of CORT and VIP were increased significantly in MC group (P<0.05). As compared with MC group, after 4 weeks of treatment, the serum levels of SP were signifcicantly increased in low intensity of EA group (P<0.01). Low and high intensities of EA could increase the stool frequency, improve the FC patient's anxiety and depression, reduce the serum levels of CORT, and increase the serum levels of SP and VIP effectively. It is concluded that both low and high intensities of EA are effective for FC patients, but there is no significant difference between the low and high intensities of EA.

AIM To investigate the neuroprotective effects and possible mechanisms of saponins from Anemarrhena asphodeloides Bge. (SAaB) on neuronal damage induced by amyloid β-protein fragments 25-35 (Aβ25-35). METHODS Cultured mouse peritoneal macrophages were stimulated with Aβ25-35 (20 μmol·L-1) for 0.5, 1, 2 and 6 h or preincubated with SAaB (10, 30 and 100 μmol·L-1)for 10 min or mitogen-activated protein kinase (MAPK) specific inhibitors (p38 MAPK inhibitor SB 203580 and MEK specific inhibitor PD98059) for 30 min prior to the addition of Aβ25-35(20 μmol·L-1). After stimulation with Aβ25-35 for the indicated times, total cellular extracts were prepared for Western blotting of extracellular signal-regulated kinase (ERK) and p38 MAPK. After stimulation with Aβ25-35 for 48 h, the supernatants of cultured macrophages were collected for quantification of tumor necrosis factor-α (TNF-α) and nitric oxide (NO) and protein expression of inducible nitric oxide synthase (iNOS) in macrophages was determined by immunocytochemical staining. To determine whether SAaB has protective effect against neuronal apoptosis mediated by Aβ25-35-induced macrophages activation, macrophages were stimulated with Aβ25-35 in the presence or absence of SAaB (10, 30 and 100 μmol·L-1) for 48 h and then the cell-free supernatant of Aβ25-35-stimulated macrophages was transferred to the culture of cerebellar granule neurons for 72 h. Neuronal apoptosis was quantitated by scoring the percentage of cells with apoptotic nuclear morphology after Hoechst 33258 staining. RESULTS Aβ25-35(20 μmol·L-1) significantly induced increase in phospho-ERK1/2 and phospho-p38 MAPK protein expression without affecting total protein levels and in the production of TNF-α and NO in cultured macrophages. Aβ25-35-induced increase of TNF-α production in macrophages involved activation of ERK1/2 signal pathway. Importantly, TNF-α and NO generated by cultured macrophages after Aβ25-35 stimulation may be responsible for the majority of the neuronal apoptosis. SAaB (30 and 100 μmol·L-1) significantly suppressed Aβ25-35-induced increase in phospho-ERK1/2 and phospho-p38 MAPK protein. In addition, SAaB (10, 30 and 100 μmol·L-1) also decreased the level of TNF-α and NO in supernatants of cultured macrophage and inhibited Aβ25-35-induced increase in iNOS protein expression of macrophages. Neuronal apoptosis mediated by Aβ25-35-induced macrophage activation was also significantly attenuated by treatment with SAaB (10, 30 and 100 μmol·L-1). CONCLUSION SAaB protects neurons against the neuronal cell death induced by Aβ25-35. The beneficial effects of SAaB may be related to the reduction of TNF-α and NO from activated macrophage induced by Aβ25-35.

Objective To explore associations between SG13S114A/T and SG13S32A/C polymorphisms of ALOX5AP gene and the genetic susceptibility of ischemic cerebrovascular diseases (ICVD) in Henan Han population.Methods Two hundred and forty-six ICVD patients and 245 healthy controls were recruited from Han population in Henan province. Polymorphisms of SG13S114A/T and SG13S32A/C in ALOX5AP gene were genotyped in these samples by SnaPshot minisequencing method.Each genotype frequency and allele frequency were statistically analyzed and compared between ICVD group and control group using SPSS16.0 software.Haplotype and linkage disequilibrium were analyzed by SHEsis software.Results The SG13S114 AA genotype frequency ( 18.7% ) and A allele frequency (41.3%) in ICVD group were significantly higher than those in control group (9.0% and 32.7%,respectively; P =0.002 and P =0.005 ).It was also found that in male ICVD group and in younger ICVD group ( <50 years old),the SG13S114 AA genotype frequencies (22.1% and 22.0%,respectively) and A allele frequencies (42.1% and 42.7%,respectively) were significantly higher than those in male control group and younger control group (SG13S114 AA genotype:9.0% and 8.9% ; P =0.010 and P =0.006,respectively) ;A allele frequencies,34.0% and 32.0% ; P =0.048 and P =0.020,respectively.Finally,the prevalence of A-A haplotype in ICVD group was significantly higher than that in control group(30.4% vs 23.5%,OR =1.419,95% CI 1.068-1.885,P =0.015).T-C haplotype frequency of ICVD group was significantly lower than that in control group (22.0% vs 28.8%,OR =0.698,95% CI 0.523-0.932,P =0.014 ).Conclusions The A allele in SG13S114 loci of ALOX5AP may be a genetic risk factor for ICVD in Han population in Henan province.The association is predominant in ICVD patients of male and younger than 50 years old.Maybe A-A haplotype increases the risk of ICVD and T-C haplotype and has a protective effect against ICVD in Henan Han population.

Objective To explore the associations between coagulation factor Ⅶ (FⅦ)polymorphisms and its haplotype with risk of ischemic cerebrovascular diseases (ICVD) in Henan Han population. Methods Five hundred and twelve cases with ICVD as patient group and 560 healthy subjects as control were recruited in the study. The polymorphisms of R353Q, 5'F7 and IVS7 were detected by PCR-RFLP. The genotype frequency and allele gene frequency were compared between ICVD group and control group. The haplotype was analyzed by SHEsis software. Results The RQ genotype frequencies and Q allele frequencies of ICVD group were significantly lower than those of control group. The distribution of H7 allele frequencies and H6H7 genotype frequencies of FⅦ/IVS7 polymorphisms had significant difference between ICVD group and control group. Finally, the prevalence of R-P0-H6 haplotype in ICVD group(53. 3% )was higher than that in control group (47.5%, OR = 1. 219, 95% CI 1. 028-1. 446,P =0.023). Conclusions In Henan Han population, the Q allele of F Ⅶ/R353Q polymorphisms and the H7 allele of F Ⅶ/IVS7 polymorphisms may be protective genetic factors against ischemic cerebrovascular disease, and the R-P0-H6 haplotype may be a risk factor of ischemic cerebrovascular disease.
