Objective:To investigate plasma contents of ?-endorphin(?-EP) in patients with coronary heart disease(CHD) and study the relationship between myocardial function and ?-EP in these patients.Methods:At 12,24,48,and 96 h and 7 d after episode,the plasma levels of ?-EP were measured by immunoradiometric assay(IRMA).The left ventricular ejection fraction(LVEF) was measured with echocardiography and the class of cardiac function was assessed according to NYHA. Results:The plasma levels of ?-EP in 58 patients with CHD were higher than those in 20 healthy subjects(P

Cardiac complications(cerebral-cardiac syndrome) very often induced by acute traumatic brain injury include abnomal ECG, decreased myocardial contractile function, increased myocardial enzymes and pathological changes etc. In order to better understand the cerebral-cardiac syndrome related to the traumatic brain injury, the major clinical features, mechanism and clinical significance are reviewed.

Through G protein coupling and intracellular signal transmission, opioid peptides and its receptors in myocardial tissues participate in IPC have the function of early and delayed protection. The molecular mechanism of ”trigger-regulatory medium-effector” is of great significance in the study of the pathogenesis of IPC, as well as exploring the new idea for CHD prevention and cure.

Objective:To assess the therapeutic effects and adverse reactions of MS Contin in the treatment of acute myocardial infarction (AMI). Methods: 42 AMI patients were divided into experiment group and control group. Experiment group were given oral administration of MS Contin for 1 week besides the routine treatment of AMI for patients in the control group. Results: Between the two groups, the differences in the product of heart rate and blood pressure ( HR?BP) , the frequency of angina pecto-ris attack, the recovery time of the ST segment and the incidence of acute arrhythmia were significant. The most common side effects observed were: vomiting, constipation, hallucination, and the most severe toxic side effect was respiratory inhibition. Conclusion : In the treatment of AMI, MS Contin could relieve the pain effectively, reduce the incidence of angina pectoris attack and severe arrhythmia, decrease myocardial oxygen consumption, have tolerable side effects in the majority of patients. It is preferable to use MS Contin as a concurrent treatment of AMI.

This paper describes a detailed procedure for updating of GP TM210 treadmill system without changing the application software.By changing the hardware of computer and updating the operation system,the performance is improved greatly.

BACKGROUND: Human umbilical cord blood stem cells have been widely used in the study of spinal cord injury, but in vitro differentiation of human umbilical cord blood stem cells (hUCBSCs) has been limited by various factors. Mongalian medicine axillary choerospondias fruit extract has protective effects on neural cells, but the action mechanisms are unclear. OBJECTIVE: To observe promoting effects of 3 kinds of Mongalian medicine axillary choerospondias fruit extracts on in vitro differentiation of hUCBSCs. METHODS: Fresh umbilical cord blood was obtained from healthy puerperants to prepare hUCBSC suspension. The purified hUCBSCs were incubated in 40 petri dishes. The Mongalian medicine axillary choerospondias fruit extracts were divided into: sample 1 group: ethanol extraction, ethyl acetate extraction, crude drug mass concentration was 8.25 g/mL; sample 2 group: ethanol extraction, NKA resin isolation, 10% ethanol eluting concentration, crude drug mass concentration was 1.72 g/mL; sample 3 group: ethanol extraction, NKA resin isolation, 70% ethanol eluting concentration, crude drug mass concentration was 2.41 g/mL; control group: incubation of 80% DMEM containing 20% calf serum. Effects of various mass concentrations of Mongalian medicine axillary choerospondias fruit extract on hUCBSCs proliferation were observed. Proportion in S phase was measured using flow cytometry at 24 and 72 hours. RESULTS AND CONCLUSION: The proliferation of hUCBSCs was not significant in the sample 3 group. At day 10, the proliferation was significantly greater in the sample 1 and 2 groups compared with the sample 3 and control groups (P < 0.01). The number of hUCBSCs was significantly increased at 24 and 72 hours in S phase in the sample 1 and 2 groups. Mongalian medicine axillary choerospondias fruit extract (crude drug mass concentration 8.25, 1.72 g/mL) could promote in vitro proliferation of hUCBSCs.

We have been in charge of the teaching of the curriculum of Obstetrics & Gynecology for foreign students from Pakistan since the year of 2005,and hitherto there have been two grades of foreign students who have received this course.We have accumulated some experience through the practice of teaching,and discovered some shortcomings and problems,which are summarized as three respects:teachers and equipment,study of students,and cooperation of patients.In allusion to the shortcomings and problems,we think that we should take measures and make improvement in the respects of teachers,students,patients and so on,in order to improve the quality of the teaching for foreign students in our school.

Objective: To investigate the dynamic changes in the content of endothelin(ET) in the plasma of coronary heart disease(CHD) patients and the relationship between myocardial function and ET.Methods: The plasma ET levels of 62 CHD patients were measured by immunoradiometric assay(IRMA) at 12 h,24 h,48 h,96 h and 7 d after the attack of CHD.The left ventricular ejection fraction(LVEF) was detected by echocardiography and the cardiac function was assessed according to the NYHA classification criteria.Results: The plasma ET level was significantly higher in the CHD patients than in the healthy controls(P

This paper introduces the basic principle,structure of Holter analysis system as well as its introduction,clinical application and development in China.In addition,it also lists some common errors which occurred in the use of the equipment in the past few years and their solutions.

Objective To evalute the indication and clinical application value of microwave abla-tion in spleen-preserving surgery in treament of patients with traumatic rupture.Methods The clinical data of 45 patients with traumatic splenic rupture were retrospectively analyzed.Spleen preserving surgery was feasible by preoperative CT evaluation and intraoperative observation.36 patients received simply mi-crowave ablation,and 9 cases received microwave ablation assisted partial splenectomy.Postoperative com-plications were observed,and the changes of platelet in peripheral blood were detected before and after op-eration in the 3 th,7th,14th day to evaluate the function of spleen.Results 15 patient was complicated with left pleural effusion,1 patient was complicated with splenic fossa fluid associated with infection.Dur-ing the follow-up of at least 2 months,No patients had postoperative bleeding,hemoglobinuria,gastrointes-tinal leak,deep vein thrombosis and pancreatic leak complications,no deaths.Seven days after microwave ablation spleen-preserving surgery,blood platelet count were significantly higher than the levels before the operation (P <0.05)in spleen-preserving patients.Platelets were no statistically significant after operation in the 3 th,14thday compared with the preoperative(P >0.05).The CT scan and the ultrasonic examina-tion that reviewed after operation in the 30-60th day showed good in spleen imaging in spleen-preserving patients,No patients had portal vein thrombosis.Conclusion Microwave ablation spleen-preserving sur-gery in the treatment of partial traumatic splenic rupture will be a safe and effective operation which could expand the spleen-preserving indication and be used in clinical practice.
