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 To compare the effect between autologous fascia and artificial duramater in duramatral neoplas ty.Methods A total of 140 patients with hypertensive intracerebral hemorrhage who underwent craniotomy in Zhoukou Hospital of Traditional Chinese Medicine from February 2014 to May 2017 were selected.The patients were divided into observation group (n =90) and control group (n =50) according to dural repair method.The autologous fascia was used to repair dura mater in the observation group,and the artificial duramater was used to repair dura mater in the control group.The Glasgow Coma Scale (GCS) score,activity of daily living(ADL) and the incidence of postoperative complication were compared between the two groups.Results The eusemia rate of ADL in the observation group and the control group was 98.89％ (89/90) and 90％ (45/50) respectively at three months after operation,the eusemia rate of ADL in the observation group was significantly higher than that in the control group (x2 =6.191,P ＜ 0.05).There was no significant difference in GCS score between the two groups before operation (t =2.362,P ＞ 0.05),the GCS score at three months after operation were significantly higher than that before operation in the two groups (t =7.123,9.612;P ＜ 0.05),the GCS score in the observation group was significantly higher than that in the control group at three months after operation (t =5.710,P ＜ 0.05).The incidence of postoperative cerebrospinal leak,incision infection,cenencephalocele and epilepsy was 1.11％ (1/90),1.11％ (1/90),2.22％ (2/90) and 3.33％ (3/90) respectively in the observation group;and the incidence of postoperative cerebrospinal leak,incision infection,cenencephalocele and epilepsy was 10.00％ (5/50),8.00％ (4/50),12.00％ (6/50) and 14.00％ (7/50) respectively in the control group;the incidence of postoperative cerebrospinal leak,incision infection,cenencephalocele and epilepsy in the observation group was significantly lower than that in the control group (x2 =6.191,5.704,5.514,4.429;P ＜ 0.05).Conclusion The autologous fascia is easy to suture,and there is no rejection reaction.It can significantly improve the prognosis of patients and reduce the incidence of complications in duramatral neoplasty.

Multilocus sequence typing (MLST) is a molecular genotyping method based on nucleotide sequencing. The procedure of this method characterizes isolates of bacterial species using the DNA sequencing of multiple housekeeping genes(usually seven). For each housekeeping gene, the different sequences present within a bacterial species are assigned as distinct alleles.For each isolate, the alleles at each of the loci define the allelic profile or sequence type (ST). MLST has the advantages of being robust (based on genetic data) and electronically portable to generate data that allow rapid and global comparisons between different laboratories. In this paper, the principle, method, data analysis, application, advantages and flaws of MLST are introduced.

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.

There are no convenient techniques to evaluate the degree of facial nerve injury during a course of acupuncture treatment for Bell's palsy. Our previous studies found that observing the electrical response of specific facial muscles provided reasonable correlation with the prognosis of electroacupuncture treatment. Hence, we used the new method to evaluate the degree of facial nerve injury in patients with Bell's palsy in comparison with the House-Brackmann scale. The relationship between therapeutic effects and prognosis was analyzed to explore an objective method for evaluating Bell's palsy.

Objective To evaluate the geometry of mitral valve and annulus in patients with mitral regurgitation, and to quantify the mitral annular remodeling and motion in ischemic mitral regurgitation (IMR) with mitral valve assessment (MVA) software. Methods Seventeen patients were divided into two groups: IMR group (n=10) and non-IMR group (n=7), and other 11 patients without significant mitral regurgitation (＜2+) and mitral structure abnormality were regarded as control group. The imaging was analyzed offline with Siemens MVA software to measure the annular diameters, annular circumference, anterior and posterior annular length, annular area (MAA) and non-planar angel (NPA). The dynamic changes during the cardiac cycle were calculated. Results Compared with control group, the posterior annular length and NPA significantly increased in IMR group (P＜0.05, P＜0.01). During the systole, the posterior annular and annular circumference paradoxically prolonged in IMR group compared with control group (median Δ posterior annular length: -2.71 mm/m2 vs 0.52 mm/m2, P＜0.05). In all patients of non-IMR group, the geometric character of mitral valve lesions shown in 3-dimensional echocardiography was accordant with surgical findings. Conclusion Three-dimensional echocardiography combined with MVA software provides a useful tool for assessment the geometric character of mitral valve lesions and quantification of mitral annulus remodeling, which is helpful to understand the mechanism of MR and guide surgical treatment.
