Objective To investigate the association between the genetic variant of miRNA-1 target gene COG6 rs9548934 C→T and the risk of premature coronary artery disease (pCAD).Methods This study included 226 pACD patients and 275 gender and age matched pCAD-free controls hospitalized in our hospital,diagnosis was made based on coronary angiography ( CAG ) results.The genotypes of miRNA-1 target gene COG6 rs9548934 C→T were detected by PCR-RFLP.Results Compared with the wide genotype CC,subjects with the variant genotypes CT of rs9548934 C→T was associated with a 45％ lower risk of pACD (adjusted OR =0.55,95％ CI =0.36 -0.82,P =0.003),and the subjects with CT/TT genotypes were also associated with a significantly lower risk of pACD ( adjusted OR =0.64,95％ CI =0.44 - 0.92,P=0.015).Using the median serum TG level (1.20 mmol/L) in control group as the cutoff value,subjects with higher serum TG levels were associated with increased risk of pACD after adjustment for age,gender and BMI ( adjusted OR =2.32,95％ CI =1.57 - 3.41,P ＜ 0.001 ).In addition,subjects with higher HDL-C levels were associated with significantly lower risk of pACD ( adjusted OR =0.48,95％ CI =0.31 -0.75,P =0.001 ).Stratified analyses showed that the risk reduction for pCAD in CT/TT genotypes carriers was more significant in the female subjects ( adjusted OR =0.54,95％ CI =0.30 - 0.97,P=0.040),and in subjects with lower TG,TC,HDL-C and LDL-C levels (adjusted OR =0.62,95％ CI =0.39 - 0.98,P =0.040; adjusted OR =0.55,95 ％ CI =0.35 - 0.85,P =0.008; adjusted OR =0.43,95％CI=0.22-0.87,P=0.018; adjusted OR=0.49,95％CI=0.32-0.75,P=0.001,respectively).Conclusion The polymorphism of miRNA-1 target gene COG6 rs9548934C→T is associated with lower risk of pCAD,especially in female subjects and subjects with lower serum lipid levels.

BACKGROUNDThe blood vessels of a transplanted organ are the interface between donor and recipient. The endothelium in the blood vessels is thought to be the major target for graft rejection. Endothelial cells of a transplanted organ can be of recipient origin after transplantation. In this study, we tested whether endothelial chimerism correlated with the graft rejection and cold ischemia.

METHODSWe studied the biopsy samples from 34 renal transplants of female recipients who received the kidney from a male donor for the presence of endothelial cells of recipient origin. We examined the tissue sections of renal biopsy samples by fluorescence in situ hybridization (FISH) for the presence of endothelial cells containing two X chromosomes using a biotinylated Y chromosome probe and digoxigenin labelled X chromosome probe, and then analyzed the relationship between the endothelial cell chimerism and the rejection and cold ischemia.

RESULTSEndothelial chimerism was common and irrespective of rejections (P > 0.05). The cold ischemic time of chimerism group was longer than no chimerism group ((14.83 +/- 4.03) hours vs (11.27 +/- 3.87) hours, P < 0.05).

CONCLUSIONSThere is no correlation between the percentage of recipient endothelial cells in vascular endothelial cells and the type of graft rejection. The endothelium damaged by ischemic injury might be repaired by the endothelial cells from the recipient.

OBJECTIVETo explore influence factors of dietary supplement used in population aged above 45 years in Beijing.

METHODSUtilizing the data of the survey of dietary supplement (DS) used in Beijing in 2006 was to investigate the influence factors by using multi-factorial logistic regression analysis.

RESULTSAll 2487 samples were included in the analysis. Sex, age, average income of each month for each member of the family, experiences of deficiency of nutrition, attitude to nutrition knowledge, attitude to the need of DS and city-or-rural resident had shown effects on DS using. The percentage of using DS in female was higher than that in male being 19.3% and 11.8% respectively. The percentage grew up as the age became older. The same trend appeared as the economic-status going up, but not as education level change. Use of DS was greater in urban population (16.9%) than in rural population (14.6%). The percentage of using DS in people who had or just been diagnosed as malnutrition/deficiency disease or chronic disease, or those who thought themselves having got these diseases only by their own feeling were higher than those did not.

CONCLUSIONPeople the female, the elder, or those having higher income, having experiences of deficiency of nutrition, are more interested in nutrition knowledge, and more positive in need of DS and those living in rural should be the target population of nutrition education for DS use.

OBJECTIVETo evaluate the cost-effectiveness of combining Chinese medicine (CM) with Western medicine (WM) for ischemic stroke patients.

METHODSHospitalization summary reports between 2006 and 2010 from eight hospitals in Beijing were used to analyze the length of stay (LOS), cost per stay (CPS), and outcomes at discharge.

RESULTSAmong 12,009 patients (female, 36.44%; mean age, 69.98±13.06 years old), a substantial number of patients were treated by the WM_Chinese patent medicine (CPM)_Chinese herbal medicine (CHM) (38.90%); followed by the WM_CPM (32.55%), the WM (24.26%), and the WM_CHM (4.15%). With adjustment for confounding variables, LOS of the WM_CPM_CHM group was about 10 days longer than that of the WM group, and about 6 days longer than that of the WM_CPM group or the WM_CHM group (P<0.01); CPS of the WM_CPM_CHM group was United States dollar (USD) 1,288 more than that of the WM group, and about USD 600 more than that of the WM_CPM group or the WM_CHM group (P<0.01). Compared with the WM group, odd ratio (OR) of recovered and improved outcome of the WM_CPM_CHM group was the highest [OR: 12.76, 95% confidence intervals (CI): 9.23, 17.64, P<0.01], OR of death outcome of the WM_CPM_CHM group was the lowest (OR: 0.08, 95% CI: 0.05, 0.12, P<0.01). There was no significant difference between LOS, CPS and OR of the WM_CPM group and those of the WM_CHM group (P>0.05). Cost/effectiveness and incremental cost-effectiveness ratio of the WM_CPM_CHM group were robustly higher than those of the WM group.

CONCLUSIONCompared with WM alone, supplementing CPM and CHM to WM provides significant health benefits of improving the chance of recovered and improved outcome, and reducing the death rate, at an expense of longer LOS and higher CPS.

OBJECTIVE: To compare the effect of acupoint injection and intramuscular injection with mouse nerve growth factor (mNGF) on gross motor function development of children with cerebral palsy (CP), and explore the treatment mechanism. METHODS: A total of 63 children with CP were randomly divided into an observation group (32 cases, 4 cases dropped off ) and a control group (31 cases, 3 cases dropped off). Based on the routine rehabilitation therapy, the control group received intramuscular injection of mNGF(18 µg/2 mL), and the observation group received acupoint injection of mNGF at Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23), Sanjiaoshu (BL 22), Shenting (GV 24), Baihui (GV 20), Fengfu (GV 16), Dazhui (GV 14), etc. Of them, 5-6 acupoints alternately were selected each time, and each acupoint was given 0.3-0.5 mL, totally 18 µg/2 mL. Both treatment were carried out once every other day for six months. Before and after treatment, the children's development of brain function was assessed using gross motor function classification system (GMFCS). Before treatment (T), after 2 (T), 4 (T) and 6 (T) months of treatment, the motor function was evaluated by gross motor function measure (GMFM-88). The systolic peak velocity (Vs), mean velocity (Vm) and vascular resistance index (RI) of anterior cerebral artery (ACA) and middle cerebral artery (MCA) were measured, and the level of N-acetyl aspartate acid (NAA), choline (Cho), lactate (Lac) and creatine (Cr) from the basal ganglia, thalamus and periventricular white mater were detected by magnetic resonance spectroscopy (MRS) technology with MAGNETOM Skyra3.0T magnetic resonance imaging system before and after treatment. RESULTS: Compared with before treatment, the GMFCS classification of the observation group after treatment was significantly improved (<0.05); after treatment, the difference of GMFCS classification between the two groups was not significant (>0.05), however, the observation group had a 3.142 times of feasibility for good gross motor function development by more than level 1 compared to the control group (<0.05). After 2, 4, and 6 months of treatment, the GMFM-88 scores of the two groups showed an upward trend (<0.01), and the increase of the observation group was greater than that of the control group (<0.05). Compared with before treatment, in the ACA and MCA, the Vs and Vm increased, RI decreased in both groups after treatment (<0.01), and in the brain, NAA/Cr increased, Cho/Cr and Lac/Cr decreased (<0.01), and after treatment, the Vs, Vm of ACA and MCA and NAA/Cr of brain in the observation group were higher than those in the control group (<0.05), and the RI of ACA and MCA and Cho/Cr and Lac/Cr of brain in the observation group were lower than those in the control group (<0.05). CONCLUSION The mNGF acupoint injection has a better effect on the gross motor function in the children with cerebral palsy compared with the intramuscular injection, and the mechanism may be associated with exhibiting the double effects of acupoint effect and the targeting therapy of drug, which can effectively improve the cerebral hemodynamics and the metabolism of cerebral nervous substances.

To investigate the effects of isovitexin Ⅳ on transient outward potassium current in rat ventricular myocytes. In this study, MTT assay was used to investigate the safe range of isovitexin. The results showed that the IC₅₀ of the drug was in the range of 10-30 μmol•L⁻¹, and the drug concentration of 1-3 μmol•L⁻¹ for the patch clamp test was within the safe range. In addition, the single ventricular myocytes were obtained by single-enzymatic hydrolysis through aortic retrograde perfusion. The transient outward potassium current (Ito) of rat ventricular myocytes was guided and measured by whole-cell patch-clamp technique and the changes of current characteristics were recorded after isovite was applied. When the concentration of IV was less than 0.1 μmol•L⁻¹, there was no significant effect on Ito. However, with the increase in the concentration of IV (≥0.3 μmol•L⁻¹), the peak of Ito was decreased gradually, from (32.32±2.9) pA/pF to （25.83±4.3） pA/pF, 1 μmol•L⁻¹ IV and (19.51±3.5) pA/pF, 3 μmol•L⁻¹ IV respectively, with an inhibition effect in a concentration-dependent manner. In the range of 1-3 μmol•L⁻¹, IV down-regulated the I-V curve of Ito significantly. The activation curve showed that IV can enable the maximum half activation potential (V1/2) to move to the positive direction, and the V1/2 was increased from (19.59±1.6) mV to (22.81±1.7) mV and (28.86±1.4) mV at concentration of 1, 3 μmol•L⁻¹, meanwhile the activation curve moved to the right. However, the maximum half inactivating potential (V1/2) of the steady-state inactivation curve of Ito was significantly decreased from (－51.43±0.99) mV to (－61.81±1.3) mV with concentration of 1 μmol•L⁻¹ and (－71.50±1.4) mV with concentration of 3 μmol•L⁻¹. The inactivation time constant of recovery from inactivation (τ) was up-regulated significantly from (94.89±0.73) ms to (118.5±1.5) ms and (162.4±1.4) ms at concentration of 1, 3 μmol•L⁻¹ respectively. Meanwhile IV could enable the inactivation recovery curve to move to the right, which suggested that it can prolong the recovery time from inactivation of the transient outward potassium channel. In conclusion, isovitexin had a high inhibitory effect on Ito in rat ventricular myocytes.

Objctive To investigate the protective effect of resveratrol on oxidative stress damage of follicular granulosa cells induced by hydrogen peroxide. Methods Granulosa cells were collected from the follicular fluid of in vitro fertilization(IVF) patients after oocyte retrieval and cultured. The cultured granulosa cells were divided into four groups: control group, injury model group, 10 μmol / L resveratrol group and 50 μmol / L resveratrol group. Cell viability was determined by CCK-8 assay, malondialdehyde(MDA) content by thiobarbituric(TBA) assay, superoxide dismutase(SOD) level by water soluble tetrazdium-1(WST-1) assay, apoptosis by AnnexinV-FITC / PI double-staining flow cytometry, Bcl-2 and Caspase-3 protein expression by Western blotting, and progesterone secretion by competitive ELISA. Resutls Compared with the control group, the cell viability, SOD level, Bcl-2 protein expression and progesterone secretion were significantly decreased in the injury model group, while MDA content, apoptosis rate and Caspase-3 apoptotic protein expression were significantly increased (P<0. 05) . Compared with the injury model group, the 10 μmol / L resveratrol group showed no statistically significant differences in various parameters; however, the cell viability, SOD level, progesterone secretion, and Bcl-2 and silent information regulator factor 2 related enzyme 1(SIRT1) protein expression were significantly increased, and the MDA content, apoptosis rate, and Caspase-3 apoptotic protein expression were significantly decreased in the 50 μmol / L resveratrol group (P < 0. 05) . Conclusion 50 μmol / L resveratrol can increase the activity of SIRT1, enhance the anti-oxidation and anti-apoptosis ability of granulosa cells and improve the function of granulosa cells.

The peeled root,stem or twig of Syringa pinnatifolia is a representative Mongolian folk medicine with the effects of antidepression and pain relief. It has been used for the treatments of heart tingling,heart palpitations,upset,insomnia and other symptoms. Inspired by Mongolian medical theory and clinical practices,this study evaluated the analgesic effect of S. pinnatifolia ethanol extract( T) through three analgesic models including acetic acid writhing test,formalin test,and hot plate test,and the sedative effect of T was evaluated by locomotor activity and synergistic sleeping experiments,and furthermore the effects of T on the GABAergic nervous system were investigated by ELISA,immunohistochemistry,Western blot,and PCR methods. The results showed that T can significantly reduce the number of writhing,the time of paw licking and extend the thermal threshold of mice,suggesting the analgesic effect of T.T also can indicate its sedative effect by reducing the number of activities,decreasing latency of sleeping and extending sleeping time of mice. ELISA results showed that T can increase the content of GABA/Glu in rat cortex,hippocampus,and hypothalamus,and the most significant increase in hypothalamus. The immunohistochemistry and Western blot results showed that T can up-regulate the expression of GAD67 protein in hypothalamus,and the PCR results showed that T can up-regulate the expression of GABAA Rα1,α2,α3,α5,β1-3,γ1-3 genes,suggesting a sedative effect through the GABAergic nervous system. In conclusion,this study shed insight into the theoretical basis and clinical application of S. pinnatifolia,and also provides inspiration for subsequent development and application.
