Objective To explore the changes and clinical significance of iron metabolism indexes such as serum ferritin (sFn),serum transferritin (sTf),serum transferritin receptor (sTfR) in patients with hematologic malignant disease before and after treatment.Methods Fifty-nine patients with hematologic malignant disease were enrolled.We measured the blood routine,bone marrow routine and iron bound of bone marrow cells and sFn、sTf、sTfR before and after treatment.The control group was 43 healthy Volunteers.Result Before treatment the level of patients sFn increased obviously,which was higher than that of control significantly (P ＜ 0.05).After chemotherapy,the level of sFn in remission group decreased obviously,which was still higher than that of normal control.sFn expression in non-remission group was not different from that before therapy or normal control (P ＞ 0.05).The level of sTf was lower than that of control significantly pretreatment and aftertreatment (P ＜ 0.05).While there was no different between remission group and nonremission group after chemotherapy (P ＞ 0.05).The level of sTfR in non-remission group after chemotherapy was higher than that of control.Correlation analysis showed that there was positive correlation between the serum level of sFn and the original and naive bone marrow cells (r =0.347).And there was negative correlation between sFn and hemoglobin (r =-0.207).But there was no significant correlation between sFn and bone marrow iron.Conclusions It is possible to predict treatment response and prognosis in hematologic malignant disease by the decrease of sFn after chemotherapy.But sTf and sTfR are not good indexes to predict treatment response in a short time.Prevalence of anemia among patients with tumor was not only because of iron deficiency.So iron supplementation should be cautious.

Objective To explore the feasibility of clinical applications of the transvaginal cavity mirrors operation on treating ectopic intra-uterine device (IUD) in uterus.Methods The clinical information was collected about 2 patients who suffered from ectopic IUD in pelvic and underwent transvaginal laparoscopic surgery.Results Ectopic devices were taken out by transvaginal laparoscopy operation in all two cases.The operation time was short and quick recovery was quickly.Conclusion Transvaginal laparoscopy operation was proved as a minimally invasive method for ectopic IUD in uterus.

The essential purpose of medical education is to cultivate qualified medical talents for health career.In the course of medical edUCation reform.it is the most important task to focus on the specjalties of mealical education,to follow the rules from medical education,to make jnnovations on the basis of practical conditions and to develop medical edUCation by means of innovation.

With the gradual transformation of the American medical model from biomedical medel to bio-psycho-social model,the advancement both in the medical security and service system,preventire medicine as well as the protection of environment have been emphasized,while the revolution of the medical education has been carried out according to the divemified requirements of the bio-psyeho-social model,and the focus of health care has been moved forward.

Objective To investigate and compare the impacts of health education and psychological intervention on the clinical effects of patients with hypertension. Methods 102 hypertension cases were collected and were randomly divided into three groups, health education group (36 cases), psychological intervention group (30 cases) and comparison group (36 cases). Compliance with prescription,anxiety level and blood pressure were observed both before and after the health education and psychological intervention. Result After health education,compliance with prescription in health education group was significantly improved ( P ＜ 0. 01 ), and blood pressure control of health education group was more preferable than the comparison group ( P ＜ 0. 01 ). After psychological intervention,anxiety level in psychological intervention group was significantly decreased ( P ＜ 0. 05 ), and blood pressures control of psychological intervention group was more preferable than the comparison group ( P ＜ 0. 01 ). Blood pressures had no statistical significance between health education group and psychological intervention group. Conclurion Health education could improve compliance with prescription, and paychological intervention could improve patients' mentl health, and both of them were conducive to the control of blood pressure of patients.

Medical science is both scientific and humanistic,and medical humanities education is an ever-lasting theme.To enhance residents'health,a new health service reform is being carried out by the government to promote the transformation towards the bio-psycho-social medical model.Social reality,mental environment and social factors have significant effects upon health.To impart medical humanities knowledge and cultivate quality of humanities are the missions of higher education.Based upon the practice of medical humanities education in Sun Yat-sen University and the experience of developed countries and regions,and by elaborating the theory to deepen understanding of medical humanities the author is to deal with the real needs and to enhance educational effectiveness of countermeasures.

Objective:To study the relationship between idiopathic thrombocytopenic purpura (ITP) and various virus infections in children.Methods:The human parvovirusB 19(HPV-B 19),Epstein-Barr virus(EBV),Cytomegalovirus and Coxsackie virus (CBV 1-6) were detected using ELISA test in 102 patients with ITP.Results:The HPVB-19 IgM was positive in 41 patients(40.12%).CBV1-6 IgM was positive in 28 patients(27.45%).The CMV IgM was positive in 17 patients(16.66%).The EBV IgM was positive in 7 patients(6.86% ).The total rate of these four viruses was 50.98% of the patients with ITP observed in this study.Except EBV,the virus infections positive rate in this study were significantly higher than that of control group.( P

Objective:To investigate the inhibitive effect of Astragalus injection on CCl 4-ethanol-induced hepatic fibrosis.Methods:40% CCl 4 and 5% ethanol were used to induce hepatic fibrosis.Astragalus injection group:Astragalus injection(800mg/kg?d) was administered during formation of inducing hepatic fibrosis.Model control group only received saline.After 7 weeks,all groups were compared in terms of serum examinations(HA,LN) and liver tissue examinations(change of histology,degree of hepatic fibrosis,level of SOD and MDA,and immunohistochemistry of LN).Results:Compared with model control group,treatment of rats with Astragalus injection remarkably decreased serum HA and LN levels( P

Objective: To study the relationship between the activation of hepatic stellate cell(HSC) and the early stage of liver fibrosis in experimental diabetic tree shrews.Methods: Tree shrews were divided randomly into normal control group and streptozocin(STZ)-treated group.STZ-treated animals were then divided into diabetic group and STZ control group.ALT,AST,Type Ⅳ collagen(Ⅳ-C),Laminin(LN) and Hyaluronic acid(HA) were detected respectively before and after modelling.Liver biopsy was performed at the end of the experiment(8th week).All of the liver specimens were observed in light microscope and transmission electron microscope.?-smooth muscle actin(?-SMA) was detected by immunohistochemistry and computer image analysis system.Results: Early fibrosis of the liver in diabetic tree shrews can be found by both light and electron microscope.There were some ?-SMA positive HSCs,namely,activated HSCs could be observed in the liver of diabetic group but not in other two groups.The expression of ?-SMA increased significantly in the liver of diabetic group as compared with that of other two groups.In addition,the level of expression of ?-SMA was positively correlated with the collagen area density in diabetic group.Conclusion HSC may play an important role in the development and aggravation of liver fibrosis in diabetic tree shrews.

Objective:To explore whether CD36 deficiency promotes insulin resistancein the C57BL/6 mice.Methods:Micewerefedwith a high-fat die(tn=7)for 14 weeks.Intravenous glucose tolerance tests,insulin release and tolerance tests were performed.Triglyceride and free fat acid levels in serum were measured.Results:Compared with the C57BL/6 mice,blood levels of glucose,insulin,triglyceride and free fatty acid were increased in the CD36 knockout mice.Conclusion:The CD36 deficiency indeed promotes insulin resistance in the C57BL/6 mice.
