Objective Extramedullary plagmocytoma at diagnose or during the course of multiple myeloma is rare.In order to know this entity better and explore new therapy for it,by combining with literature review,we conducted a retrospective study to describe the clinical and laboratory features of this entity and the outcome of these manirestation.Methods From January 2001 to July 2007,123 multiple myeloma patients were treated in our hospital.We analysed the clinical features of patients with extramedullary plagmocytoma at diagnose or during the course of multiple myeloma.The response to therapy was evaluated according to the EBMT criteria.Results 9 eligible patients out of 123 with MM were retrieved from the hematology department of Beijing Chaoyang hospital.The median age was 55(range:48～66)with a female/male ratio of 1/8.One patients was found to have Extramedullary and extraosseous tumor at the time of MM diagnose,and eight patients developed Extramedullary tumor during the course of the disease.Multiple sites were usually involved.Resistance to traditional chemotherapy wag frequent.With a median follow-up of 19 months(range:3～47),2 patients are alive.Median time from progression of disease to diagnose of Extramedullary disease was 4 and a half months.The median interval from diagnosis of Extramedullary disease to death was 2 months and OS was 23 months.Conclusion Extramedullary plasmocytoma is a rare manifestation of MM,with a cumulative incidence of 7.3% of MM in our department.Multiple sites are usually involved.The resistance to the traditional chemotherapy is frequent and the prognosis is very poor.The new therapy is necessarily explored.

Objective To investigate the effects of right or left transaction of cervical sympathetic trunk (TCST) on left ventricalar remodeling (LVRM) after acute myocardial infarction in rats and the mechanism. Methods Sixty-four adult mule pathogen-free SD rats (230-250 g) were randomly divided into 4 groups (n=16 each): group Ⅰsham operation (group S) ; group Ⅱ LVRM; group Ⅲ left TCST and group Ⅳ right TCST. Myocardial infarct was induced by ligation of left anterior descending branch (LAD) of coronary artery in group Ⅱ, Ⅲ and Ⅳ. Left and right TCST were performed immediately after myocardial infarct was successfully induced in group Ⅲ and Ⅳ respectively. In group S LAD and cervical sympathetic trunk were exposed but not ligated and transected. The animals were killed at 4 weeks after ligation of LAD and TCST. The weight of left ventricle was measured and left ventricle weight index calculated, Left veatricular myocardial tissue volume (V_t), the volume density of myocardial cells (V_v) and myocardial cell volmne (V_c) were quantitatively analyzed by stereological method. The c-fos mRNA expression in myocardium was determined by RT-PCR. Results The left ventricle weight index, V_t, V_c and c-fos mRNA expression were significantly increased in group LVRM (Ⅱ), left and right TCST (Ⅲ, Ⅳ) as compared with group S. Left ventricle weight index, V_v, V_t, V_c and c-fos mRNA expression were all significantly decreased in fight TCST group (Ⅳ), while left ventricle weight index, V_t, V_c and c-fos mRNA expression were significantly increased in left TCST group (Ⅲ) as compared with LVRM group (Ⅱ). Conclusion Right TCST down-regulates the increase in c-fos mRNA expression after acute myocardial infarction and inhibits the left ventricular remodeling while left TCST up-regulates the c-fos mRNA expression and promotes the development of left ventricular remodeling.

Objective To observe vasculogenic mimicry (VM) of human choroidal melanoma cell line OCM-1 cultured in vitro and the expression of PI3K and EphA2 protein,as well as to explore the possible mechanisms.Methods OCM-1 cells were cultured in vitro and stained with periodic acid Schiff (PAS) on days 7,which aimed to observe the formation of PAS-positive cyclic structures,that is,VM formation.Then immunohistochemical staining was performed to detect PI3K and EphA2 on day 1,4,7 and the results were observed.Ressults On day 4 of 3-demintional culture,most of OCM-1 cells were polygonal and the cytoplasm was abundant;the nuclei were round and the nucleoli were visible.A small part of the tumor cells were long spindle.It was found that several long spindle cells were connected to each other to form hemicyclic structure.After 7 days,a large number of tumor cells became long spindle,growing along the collagen scaffold,and long protrusions appeared,forming a ring structure.PAS staining showed that the tumor cells were mostly arranged in a row,and tumor cells imitated the formation of body blood vessels,resulting in cell band and pipeline-like cell layers,with one layer of extracellular matrix (PAS-positive substance) making up the ring structure.Moreover,the expression levels of PI3K and EphA2 on day 4 and 7 were significantly higher than those on day 1 (all P ＜ 0.05),and their expression levels on day 7 were higher than those on day 4 (all P ＜ 0.05).Conclusion EphA2 and PI3K may play an important role in the VM formation in 3-dimentional culture of human choroidal melanoma cell line OCM-1.

Objective:To investigate the relationship of family history , psychosocial factors of PD (Parkinson's Disease) in a rural population in north China. Methods: A case control study was conducted in rural population in China. Cases (n=77) have been diagnosed by a two-phase screening by neurologists and interviewers in May, 2000. Controls (n=154), randomly selected from the same cohort, who were matched with patients (control/cases ra-tio=2) for sex, age (?5 years). Information of participants' characteristics came from the interview in 2001. Data was analyzed by using conditional logistic regression by SAS 6.12. Results: Family history (OR=13.54) .negative life events (OR=3.02), interpersonal communication (OR=2.10) were associated with a significantly elevated risk for the onset of PD. Conclusion: These results indicate that family history, psychosocial factors were risk factors of PD.

Objective To study the relationship between serum lipid level with embryo quality in vitro fertilization cycle.Methods A total of 603 pairs of infertile couples who were treated with in vitro fertilization and embryo transfer technique (IVF-ET) in our hospital from October 2015 to June 2016 were collected.All subjects underwent long-term ovarian hyperstimulation,blood lipid and the embryo quality were measured and evaluated.Results Triglyceride (TG),total cholesterol (TC) and body mass index(BMI) were significantly negatively correlated with fertilization rate,2PN fertilization rate,cleavage rate and embryo rate (P<0.05).Density lipoprotein (LDL) and non-high density lipoprotein (NHDL) and lipoprotein (a) [Lp(a)] were negatively correlated with fertilization rate,2PN fertilization rate,high density lipoprotein.The cholesterol (HDL) were positively correlated with fertilization rate,2PN fertilization rate,cleavage rate and embryo rate(P>0.05).Conclusion There is a linear correlation between blood lipid level and AMI and embryo quality.Serum lipids and AMI can be used to evaluate the quality of embryo and provide suggestion for the quality control of IVF-ET.
