Objective To analyze the clinical efficacy and safety of coronary intervention in elderly patients with coronary heart disease.Methods Totally 163 middle and aged patients with coronary heart disease in our hospital were involved in this study.Clinical data of them were analyzed.Patients were divided into groups aged 75 87 years (n=64),and aged 42 74 years (n=99).After coronary artery disease (CAD) degree assessment,patients were treated with angiography and coronary intervention.Clinical efficacy and complications were compared between groups.Results All patients underwent coronary angiography.The multivessel and complex lesions were more common in aged 75-87 years of CAD patients than in aged 42-74 years of CAD patients (P＜0.05).There were significant differences in operation success rate,incidence of complications and mortality during hospitalization between the the above groups [97.0％ (96 cases) vs.87.5％ (56 cases),4.0 (4 cases) vs.12.5 (8 cases),1.0％ (1 case) vs.10.9％ (7 cases),x2=5.54,4.08,8.21,respectively,all P＜0.05].Conclusions The clinical efficacy and safety of coronary intervention is correlated with age in patients with coronary heart disease.

The tensional relationship between doctors and patients caused by medical ethics and medical ethos is becoming a hot spot at present.It's of great significance to reduce the contradictions between the medical staff and the patients and construct a harmonious doctor-patient relationship by strengthening the construction of medical ethics and medical ethos and improving the professional quality of medical staff.

Objective To explore whether physiological doses of testosterone therapy can modulate cardiomyocyte aging via classical androgen receptor (AR) dependent pathways.Methods Male C57BL/6J mice and testicular feminized (Tfm) mice were divided into five experimental groups:the control group (n=8),the castrated group (n=8),the Tfm group (n=7),the testosterone treated castrated group (n=8),and the testosterone-treated Tfm group (n =8).After isolation of cardiomyocytes from the left ventricle,the activity of superoxide dismutase (SOD) and the amount of malondialdehyde (MDA) were measured using colorimetry,and the expression of the p16INK4a and retinoblastoma (Rb) proteins was detected by Western blotting.Results Compared with the control group,the activity of SOD in the castrated group and the Tfm group declined [(16.55±1.18) U/ml,(17.30±1.32) U/ml vs.(21.57±2.21)U/ml,P＜0.05)],the amount of MDA increased [(7.78±1.27)μmol/L,(6.52±0.82)μmol/L vs.(3.48±0.70)μmol/L],P＜0.01,and the expression of both the p16INK4aand Rb proteins increased [(0.37±0.08),(0.45±0.06) vs.(0.14±0.02),forp16INK4a,P＜0.05; (0.74±0.05),(0.79±0.08) vs.(0.40±0.05),for Rb,P＜0.05].Compared with the castrated group,the activity of SOD in the testosterone treated castrated group increased [(23.00±0.58)U/ml vs.(16.55±1.18) U/ml,P＜0.01],the amount of MDA decreased [(2.63±0.90) μmol/L vs.(7.78±1.27) μmol/L,P＜0.01],and the p16INK4a and Rb proteins were both downregulated (0.13 ± 0.03 vs.0.37± 0.08),for p16INK4a,P＜0.05; (0.45 ±0.05) vs.(0.79±0.08),for Rb P＜0.05.Compared with the Tfm group,the activity of SOD in testosterone-treated Tfm group increased,the amount of MDA decreased,and the p16IN4a and Rb proteins were both downregulated (P＜ 0.05).No significant differences in these markers were detected between the testosterone-treated castrated group and the testosterone-treated Tfm group.Conclusions Physiological doses of testosterone can retard cardiomyocyte aging via androgen receptor independent pathways.

Objective:To investigate the effects of ursolic acid on proliferation and apoptosis of hepatic carcinoma cell line HepG2 and its partial mechanism.Methods:The human HepG2 cells were cultured by different concentrations of ursolic acid.The inhibitions of ursolic acid on cell proliferation were determined by using MTT.The effects of ursolic acid on on cell apoptosis and cell cycle were detected by using flow cytometry.The expressions of pERK1/2 and Cyclin D1 proteins after culturing by different concentrations of ursolic acid were tested by using Western blotting.Results:The human hepatoma HepG2 cell proliferations were inhibited by different concentrations of ursolic acid,and the effects showed dose and time-dependent manner(P＜0.05).The cell apoptosis rate for human hepatoma cell line HepG2 was achieved to the maximum under 60 μ mol/L ursolic acid for 72 h,which was (78.723 ± 3.623)％.Ursolic acid could significantly increase the Go/G1 phase cells proportion,and induce HepG2 apoptosis.Ursolic acid could inhibit the expressions of pERK1/2 and Cyclin D1 proteins,and inhibitory effects showed more apparent along with the concentration and time gradually increasing.Conclusion:Ursolic acid could inhibit the proliferation of human hepatic carcinoma HepG2 cell line,block of cells in G0/G1 phase,and promote the cell apoptosis.This might be related with down-regulation of the expressions of pERK1/2 and Cyclin D1 proteins.

Objective To evaluate the effect of immune fluorescence chromatography on glycosylated hemoglobin (HbA1c). Methods The precision of immune fluorescence chromatography was evaluated with samples of 6.0% and 8.0% fixed value. Group of High performance liquid chromatography (HPLC) as control, HbA1c for 200 samples of EDTA-K2 anti-coagulated whole blood were detected by immune fluorescence chromatography to synchronous blinded trial. Results As to the precise of immune fluorescence chromatography in the samples of 6% and 8%, values of coefficient of variation were 5.1% and 5.3%, respectively. The linear regression equation of immune fluorescence chromatography and HPLC was Y=-0.110+1.021X and the correlation coefficient was 0.982. 6.0% and 8.0% as the cut-off value, kappa values were 0.950 (P < 0.001) and 0.922 (P < 0.001), respectively. Conclusion Immune fluorescence chromatography and HPLC is consistent with detection of HbA1c, which can be used for clinical detection of HbA1c.

This paper reviewed the applications and improvements of the major three TCM nursing operations, cupping, Gua-Sha and acupressure. The future developments in moxibustion, auricular point sticking, fumigation and washing therapy and moisten compress therapy were also prospected.

Background At present,a new drug,platelet-derived growth factor-BB (PDGF-BB),as a drug knife for the treatment of glaucoma is under study to expect it directly working on the trabecular meshwork without disrupting the normal physiological structure of anterior chamber angle,clearing the trabecular meshwork aqueous outflow channel so as to achieve the purpose of lowering intraocular pressure.Objective This study aimed to investigate the effect of PDGF-BB on matrix metalloproteinase-2 (MMP-2) expression in cultured bovine trabecular meshwork cells.Methods Trabcular tissue was obtained from fresh bovine eyes,and trabcular meshwork cells were cultured and passaged using explant method.Cultured cells were identified by morphological evaluation and neuronspecific enolase (NSE) staining.The third generation of cells were inoculated to 6-well plate,and different concentrations (0,5.0,12.5,25.0 μg/L) of PDGF-BB was added into the medium for 2 hours.Expression levels (A value) of MMP-2 mRNA (MMP-2 mRNA/β-actin) and protein in the cells were assayed by reverse transcription polymerase chain reaction (RT-PCR) and immunochemistry,respectively.Results Trabcular meshwork cells appeared 5-9 days after cultured.The third generation of cells presented with many process and showed the green influence in cytoplasm.MMP-2 mRNA/β-actin value (A) was 0.127 ± 0.026,0.147 ± 0.045,0.178 ± 0.053 and 0.222±0.062 in the O,5.0,12.5,25.0 μg/L PDGF-BB group,respectively,showing a significant difference among them (F =56.71,P＜0.05),and the MMP-2 mRNA/β3-actin value in the 5.0,12.5,25.0 μg/L PDGF-BB group was elevated in comparison with that of the 0 μg/L PDGF-BB group (all P＜0.05).The expression value (A value) of PDGF-BB protein in the cells was 446.12±13.81,1444.65±54.64,2086.18±73.18,3488.65±25.98 in the 0,5.0,12.5,25.0 μg/L PDGF-BB group,respectively,with a significant difference among the four groups (F=213.12,P＜0.01),and the expression value (A value) of PDGF-BB protein was gradually increased with the ascend of concentration of PDGF-BB(all P＜0.05).Conclusions PDGF-BB can promote the expression of MMP-2 in bovine trabcular meshwork cells in vitro in concentration-dependent manner.
