A satisfaction survey carried out by Beijing Chao-Yang Hospital during the Beijing 2008 Olympic Games, found differences of patient satisfaction between locals and overseas patients in consulting environment, outpatient procedure, quality of service, quality of diagnosis and treatment. The patient satisfaction of overseas patients was lower than locals. Especially noteworthy is the low satisfaction of the former for the hospital coloring, privacy in the sector, registration, vocal communication, patient condition statement, nurse attitude and service quality. Real-time improvement in these aspects of medical services has harvested obvious progress. Results of the satisfaction survey provided valuable reference materials for large-scale activities, and ongoing improvement of medical services in the long run.

To explore the protective effects of trimetazidine on vascular endothelial cells injury induced by hydrogen peroxide (H2O2) and its pharmacological mechanisms of anti-oxidation.Methods Human umbilical vein endothelial cells (HUVECs) were injured by H2O2.Next,the cells were treated with three different concentrations of trimetazidine (1 μmol/L,10 μmol/L,100μmol/L,respectively).The viability of cells was detected by methyl thiazoeyl tetrazolium (MTT) assay.In addition,malondialdehyde (MDA)contents,superoxide dismutase (SOD) and secretion of NO were measured.Results Trimetazidine could enhance the viability of the injured HUVECs induced by oxidation,decrease the level of MDA,enhance the SOD activity,and increase the secretion of nitrogen monoxide.These effects were in a certain dose-dependent manner and the difference was significant among the three concentrations (P<0.05).Conclusions Our results suggest that trimctazidine may protect lipid peroxidation and prevent oxidation-induced cellular dysfunction of HUVECs (J Geriatr Cardiol 2008;5:248-251)

OBJECTIVE Toobservetheeffectoftemozolomide(TMZ)incombinationwithtetran-drine(TET)on cell viability,colony formation,migration and cell apoptosis of human glioblastoma U87 cells.METHODS TheviabilityofU87cellstreatedwithTET(8-64μmol·L-1),TMZ(50-400 μmol·L-1 )and TMZ combined with TET (3.2,6.4 μmol·L-1 )was detected by cytotoxicity assays with Cell Counting Kit-8 (CCK-8),the colony formation was detected by Giemsa staining,cell migration ability was detected by Transwell migration assay,cell apoptosis was assayed by flow cytometry using Annexin Ⅴ /PI double staining,and the expression of apoptosis-related proteins expression was detec-tedbyWesternblotting.RESULTS ThedataofCCK-8showedthatTET(r=0.903,P<0.05)orTMZ (r=0.995,P<0.05)could inhibit U87 cell viability alone in a concentration-dependent manner.The cell viability inhibition rate of U87 cells by TMZ co mbined with TET was higher than by TMZ or TET alone. Data showed that the effect of TMZ combined with TET was additive.TMZ 100 μmol·L-1 inhibited U87 cell colony formation and migration ablility compared with normal control.The inhibition rate of U87 cells by TMZ 100 μmol·L-1 combined with TET (3.2 and 6.4 μmol·L-1 )was more significant than by TMZ alone (P<0.05).Compared with TMZ alone,TMZ combined with TET (3.2 and 6.4 μmol·L-1 )signifi-cantly down-regulated the expression of anti-apoptotic protein Bcl-XL,but significantly up-regulated the expression of cleaved caspase 3 protein and cleaved poly(ADP-ribose)polymerase.CONCLUSION TET combined with TMZ can inhibit U87 cell viability,colony formation and migration by activating caspase-dependent apoptotic pathway,resulting in apoptosis.

ObjectiveTo study the impact of primary PCI in culprit artery on epicardial blood flow of nonculprit artery in patients with STEMI. MethodsEnrolled 117 patients with anterior wall STEMI were treated with primary PCI in the culprit artery, left anterior descending artery (LAD, as study group.Another 100 patients with normal coronary artery evidenced by angiography were enrolled as control group.The differences in CTFC (corrected TIMI frame count measured by using digital subtraction arteriography,TIMI =thrombolysis in myocardial infarction) and MBG (myocardium blood flow perfusion grading)between pre and post primary PCI in both culprit artery and nonculprit artery ( left circumflex artery, LCX),and CTFC and MBG were also detected in the subjects of control group. Blood samples were collected and the levels of CRP (C-reactive protein) were assayed. Clinical and angiographic features were analyzed.ResultsThe CTFC of nonculprit artery (LCX) and the level of MBG in patients with anterior wall STEMI were different from the level of MBG and CTFC in control group ( P<0. 05) before primary PCI. The level of MBG and CTFC in nonculprit artery (LCX) were improved (P < 0. 05 ) after primary PCI, but they did not resume to normal level. Patients without reflow in culprit artery had higher incidence of no reflow in nonculprit artery than patients with re-flow (78% vs. 8%, P < 0. 01 ), and the level of CRP in patients without reflow in nonculprit artery were higher than those in patients with re-flow ( P < 0. 05). Conclusions The perfusion of nonculprit artery may be impaired in patients with STEMI. Although the perfusion of nonculprit artery may be improved after primary PCI in culprit artery, but it was still lower than those in the control group, and inflammation mechanism might contribute to it.

OBJECTIVETo study the effects of JTS, Traditional Chinese Medicine caps. treating cerebral ischemia on metabolism and antioxidant system in cerebral ischemia rat.
METHODSI.m. dexamethasone and ligating common carotid artery, the model of cerebral ischemia rats was established to investigate the effects of JTS caps. and its mechanisms through detecting substance metabolism, energy metabolism and antioxidant system.
RESULTSJTS caps. (1.78 - 3.56 g/kg) could upgrade glucose (Glu), total amino acids (T-AA), ATP, Na(+)-K(+) -ATPase, superoxide dismutase (SOD) and catalase (CAT) of brain tissue and degrade lactic acid (LD), malondialdehyde (MDA) and water content of brain tissue in cerebral ischemia rat (P < 0.05, 0.01). JTS caps. (3.56 g/kg) could also depress extenuation of rat's body weight.
CONCLUSIONJTS caps. has some protections against the cerebral ischemia in rats, and one of the mechanisms may be improving the metabolism and antioxidant system.

OBJECTIVETo study the effects of skin wound induction gel on the glans scabbing rate, class-A wound healing rate, and wound healing time of circumcision for phimosis in pediatric patients.
METHODSWe randomly assigned 48 six to thirteen years old children with phimosis to an experimental group (n = 25) and a control group (n = 23) to be treated by circumcision. After surgery, the patients in the experimental group received application of skin wound induction gel while those in the control group received that of povidone iodine only to the glans and incision. We recorded and compared the glans scabbing rate, class-A wound healing rate, and wound healing time between the two groups of patients.
RESULTSGlans scabbing was observed in 3 cases in the experimental group and 17 cases in the control group (12.0% vs 73.9%, P < 0.01). No statistically significant differences were found in the rate of class-A wound healing between the two groups (100% vs 91.3%, P > 0.05). The wound healing time was significantly shorter in the experimental than in the control group ([10.7 ± 1.7] d vs [11.9 ± 2.1] d, P < 0.05).
CONCLUSIONPost-circumcision application of skin wound induction gel to the glans and incision can effectively reduce glans secreta, alleviate inflammatory reaction, and shorten the healing time in the treatment of phimosis in children.
