Objective To assess segmental ventricular wall motion abnormalities in patients with coronary artery heart disease by velocity vector imaging (VVI).Methods Eight-six patients of chest pain having underwent coronary angiography were selected,and were divided into myocardial ischemia group (31 cases),myocardial infarction group(25 cases) and normal group (30 cases) according to test results.All the patients were checked with ultrasonic cardiogram in specified time.Systolic rotation angle and speed,diastolic rotation speed in the bottom and apex heart of each segment (anterior,anterior septum,posterior,lateral,inferior wall,interval) was analyzed by VVI.Results Rotary motion of the left ventricle was not consistent in different segment in myocardial infarction group,and the extent and form was different compared with that in normal group.Compared with that in normal group,bottom and apex heart angle of rotation of each segment in myocardial infarction group showed significant difference (P ＜ 0.01 or ＜ 0.05).The rotation angle of each segment in apex and bottom heart between myocardial ischemia group and normal group had no statistical significance (P ＞0.05).In bottom heart:the systolic rotation speed on anterior wall,anterior septum,posterior wall and lateral wall in myocardial infarction group was statistically lower than that in normal group (P ＜ 0.01 or ＜ 0.05),and the diastolic rotation speed on anterior wall,anterior septum,posterior wall,lateral wall,inferior wall was statistically lower than that in normal group (P ＜ 0.01 or ＜ 0.05).The systolic rotation angle between two groups was not statistically significant (P ＞ 0.05).The diastoic rotation speed on anterior interval septum in myocardial ischemia group was statistically lower than that in normal group (P ＜ 0.05),the systolic rotation angle and speed,diastolic rotation speed in other segment was not statistically significant compared with that in normal group (P ＞ 0.05).In apex heart,the systolic rotation speed in anterior wall,anterior septum,posterior wall in myocardial infarction group was statistically lower than that in normal group (P ＜ 0.01 or ＜ 0.05),and the diastolic rotation speed in anterior wall,posterior wall,lateral wall,inferior wall was statistically lower than that in normal group (P ＜ 0.01 or ＜ 0.05).The diastolic rotation speed on anterior and inferior wall in myocardial ischemia group was statistically lower than that in normal group (P ＜ 0.05),and the systolic rotation angle and speed,diastolic rotation speed in other segment was not statistically significant (P ＞ 0.05) compared with that in normal group.Conclusion VVI technique in ultrasonic cardiogram can check out difference between myocardial ischemia and myocardial infarction incipiently.

Although intensive chemotherapy and hematopoietic stem cell transplant (HSCT) are currently used in the treatment of acute myeloid leukemia (AML),a large proportion of patients relapse after treatment.On the other hand,a minority of cases fail to achieve complete remission (CR) after a standard first line treatment.Leukemia relapse and refractory become the main course of treatment failure,which are also the main points and difficulties of treatment for AML.However,the most effective regimen for refractory/relapsed AML has not been established.This review focuses on the progress of the regimens and major chemotherapy for refractory/relapsed AML (except M3).

0.05);the persons with hypersexuality from 25 to 31 age had the highest infection percentage and it taken 75% of all the NGU.The minocycline and doxycycline were sensitive and ciprofloxacin was a resistant drug.CONCLUSIONS In our hospital,the Uu is still a main pathogen,and the minocycline and doxycycline are the fist choice to treat it.At the same time,the NGU survey and the antibacterial susceptibility tests are very important.

Supplementary concept records ( SCB ) can effectively supplement and expand MeSH by forming the mapping between SCB and MeSH. Chinese herbal medicine terms indentified by MeSH Browser in SCB were analyzed in aspects of their distribution,single medicine,abstracted compositions,compound prescription,classical prescription, slef-made prescription, and use frequency,which showed the supplementary concepts in relation with Chinese herbal medicine and the existed problems. Suggestions were put forward for the use of Chinese herbal medicine terms in MeSH SCB, such as promoting their standardization, and use of standard terms when scientists publish their papers and retrieve papers from databases.

AIM:To investigate the role of Herceptin in the apoptosis and drug sensitivity of endometrial canc -er Ishikawa cells .METHODS: The IC50 values of Herceptin , adriamycin ( ADR ) , cisplatin ( DDP ) and paclitaxel ( PTX) for Ishikawa cells were detected by MTT method .Ishikawa cells were treated with single drug and combined chemo-therapy for 24 h, the cell cycle and the apoptosis ratio were determined by flow cytometry .RESULTS:The IC50 values of Herceptin, ADR, DDP and PTX were 57.12 mg/L, 0.572μmol/L, 67.4μmol/L and 719.5 nmol/L, respectively.Her-ceptin significantly enhanced the cytotoxicity of the chemotherapeutic drugs , and increased apoptosis ratio statistically . CONCLUSION:Herceptin enhances the apoptosis-inducing ability of the chemotherapeutic drugs and improves the che-motherapeutic sensitivity in Ishikawa cells .

Objective:To investigate characteristics of masticatory movement path in young adults with AngleⅡ1 malocclusion.Meth-ods:1 5 youths with normal occlusion(group Ⅰ)and 1 5 with AngleⅡ1 malocclusion(group Ⅱ)were included.Mandibular movement paths of the incisal point of the incisor during unilateral-sided gum-chewing were recorded by the BioEGN mandibular kinesiography an-alyzer.Both maximal distances and directions (FH-opening/closing angles)in sagittal plane were analyzed.The statistic analyses were performed with SPSS 1 3.0 software.Results:Lateral distances of left masticatory movement path in Group I and Group II were (8.24 ±1 .48)mm and (6.58 ±2.49)mm,those of right(8.05 ±1 .05)mm and (6.42 ±2.47)mm,respectively(P <0.05).The aver-age of FH-opening/closing angle of masticatory movement path in Group I was higher than that in Group II at each level(P <0.05)ex-cept 0.5 mm point in the left masticatory movement path.Conclusion:Maximal lateral distance and FH-opening/closing angle of mas-ticatory path in young adults with AngleⅡ1 malocclusion are less than those with normal occlusion.

Objective To investigate cytotoxicity and its mechanism of bilirubin on different types of neurons of rat in primary culture. Methods Toxic effect of bilirubin on primary cultured neurons (at cerebellar oranule hippocampal and cortical neurons) was observed. Ncuron survival was detected by fluorescei diacetate (FDA) staining. Measurement of fluorescent intensity of intracellular dilirudin were performed by microspectroflurimetry imaging system. Results Biliruin induced cytotoxicity to different type neurons in a dose-dependent manner. Exposed at 8d to different concentrations of bilirubin (4.3 ?mol/L、8.6 ?mol/L and 17.1 ?mol/L); cerebellar gtanule neuron survival werc (50.1?3.1)%,(18.5?2.3)%, (2.0?2.4)%, cortical neuron survival were (90.7?7.8)%, (85.3?5.3)%,(74.5?2.4)%, and hippocampal neuron survival were (75?6)%, (62?5)%, (49?5)% respectively. The toxic effect of bilirubin on ccrebellar granule neuron was significantly higher than that on hippocampal and cortical neurons. The fluorescent intensity of bilirubin in gra- nule, hippocampal and cortical neurons were 33.4?2.3、10.7?3.0、21.9?4.3 respectively three hours after addition of bilirubin to the medium. Significantly higher bilirubin concentration was found in granule neurons than that in hippocampal and cortical neurons (P

Objective: To discuss the role of clinical pharmacists played in the pharmaceutical care for osteomyelitis patients. Methods:Clinical pharmacists participated in the treatment for a special patient with osteomyelitis. Taking the disease features, medi-cal history, adverse drug reactions into account, clinical pharmacists provided consultant opinions for establishing and adjusting the ap-propriate therapeutic regimens and individualized pharmaceutical care. Results:The drug treatment regimens for the patient were safe, effective and rational. By the individualized pharmaceutical care, clinical pharmacists were able to find the problems in the drug treat-ment and implement the efficient solutions. Conclusion: Clinical pharmacists show their own advantages in individual pharmaceutical care, and play an important role in improving the rational drug use.
