Objective To analyze and discuss the value and significance of coronary artery bypass grafts in the same period of heart valve replacement in the process of the coronary heart disease with heart valve disease treatment, in order to improve the effect of treatment and reduce the incidence of adverse events. Methods 60 cases with coronary heart disease with heart valve disease , which admitted in our hospital during February 2013-February 2015, were selected as the research objectaccording to random number table method and divided into the-experimental group and the control group , each group of 30 cases according to the principle of double blind control. The experimental group was given the coronary artery bypass grafts in the same period of heart valve replacement and the control group was given the coronary artery bypass grafts without heart valve replacement. The curative ef-fects of different schemes and effects on cardiac function after surgery of the two groups were compared. Results After statistical analysis found thatthe observation indexes of the control group was significantly increased compared with the experimental group, the difference was significant statistically significant (P<0.05). The postoperativecar-diac function indexes of the experimental group was significantly improved then control group , the difference was significant statistically significant (P<0.05). Conclusion Coronary heart disease with heart valve disease in the process of treatment can also take heart valve surgery combined coronary artery bypass surgery. By preoperative and postoperative symptomatic treatment, intraoperative protect myocardium, can effectively prevent and reduce the op-eration of various complications, which is worthy of clinical popularization and application.

Objective To observe the correlation between lipoprotein-associated phospholipase A2(Lp-PLA2) levels and coronary artery disease (CAD), extent of angiographic coronary artery lesions and risk factors of CAD in the elderly. Methods Plasma levels of Lp-PLA2, triglyceride (TG), total cholesterol(TC), low density lipoprotein(LDL-C), high density lipoprotein cholesterol (HDL-C) and high sensitivity C-reactive protein(hs-CRP) were measured in 67 elderly patients with angiographic CAD meanwhile in 23 normal controls without angiographic coronary artery lesions. The extent of coronary artery lesions was evaluated according to the number of vessel lesions (divided into single, double and triple-vessel lesions) and Gensini scoring system. Then the relationship between Lp-PLA2 and CAD was assessed. Results The plasma levels of Lp-PLA2 were significantly higher in the CAD group than in the controls [(352.7 ± 129.0) vs. (204.0 ± 59. 7) μg/L, P < 0. 01]. Lp-PLA2 levels increased with the number of coronary artery lesions and Gensini score, then were positively correlated with age(r= 0. 25, P<0. 05) ,TC(r=0. 33, P<0. 01) ,LDL-C(r=0.27, P< 0. 05),apoB(r=0. 36, P<0. 01). The levels of LP-PLA2 and LP(a) were associated with CAD by using stepwise regression analysis. Conclusions In the eldly, the levels of LP-PLA2 are much higher in angiographic CAD, and these may reflect the severity of CAD. LP-PLA2 is a risk factor for CAD.

Childhood cancers are malignancies occured during childhood,which consist of blood-lymphatic system disorders and solid tumor,usually under the age of 15 years old.Among cancers of childhood,solid tumors account for the mainly proportion and most neoplasms are embryonic origin,which are distinctly different from the adult solid tumors.The pathogenesis of children with an oncologic disease,except from the 2 major elements heredity and environment,some experts consider that there are intense correlations between various carcinogenic environment exposure during pregnancy even progestation and childhood cancers.The placenta is a combination of embryo and the maternal tissues,while is a material exchanged organ between 2 parts.One part has a same origin with fetus biological and genetics,and the other provides comprehensive guarantee for fetus normal development in utero.The research of the placental disease of childhood cancers may have a breakthrough in the study of the etiology of pediatric oncology.

Objective To compare the effect of propofol and Midazolam for the vein puncture and indicators of respiratory cycle in the e-mergency center. Methods According to different anaesthetic,100 patients who needed for central venepuncture in patients,were randomly divided into Propofol group (50 cases) and Midazolam group (50 cases),given different dose input,and evaluated by RSS(Ramsay Sedation Scale,RSS) . In terms of the onset time and recovery time of consciousness,the central venous puncture were performed with all the patients. Results There was no significant difference in the process of sedation effect on respiration and circulation of the patients between 2 groups. And the differences between 2 groups with the time of reaching RSS-5 were no statistical significance,while the differences of consciousness recovery time between 2 groups were statistical significance. Conclusion The appropriate dosage and velocity of Propofol and Midazolam can quickly achieve central vein puncture,with slight influence on respiratory and circulatory system and no serious adverse reaction. But the onset time and consciousness recovery time of the Propofol which has a good controllability was shorter than those of Midazolam.

Objective To improve the understanding of blastic plasmacytoid dendric cell neoplasm (BPDCN). Methods The clinicopathological features of 2 cases with BPDCN diagnosed in the Department of Pathology in Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College were analyzed retrospectively. The relevant literatures were reviewed as well. Results The two BPDCN patients were both elderly men with skin nodules. The tumor cells infiltrated diffusely into the whole dermis with sparing the epidermis. BPDCN cells were small to medium size with round or oval irregular nuclei and small nucleoli. Numerous mitoses figures were seen. Immunohistochemistry stain showed that CD4 and CD56 were positive and CD20 and CD3 were negative in the 2 BPDCN cases. Only 1 case was positive for CD123. Conclusions BPDCN is a rare malignant hematopoietic tumor, which is likely to involve skin. The features of morphology and immunophenotype are crucial to make correct diagnosis.

Objective: To explore the relation between hepatic lipase (HL) promoter-514C/T polymorphism and coronary heart disease (CHD) in population of this district. Methods: Polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) was used to measure HL promoter-514C/T genotypes in 199 CHD patients (CHD group) and 146 non-CHD patients (non-CHD group) in order to explore its influence on blood lipids and apolipoprotein. Results: In male group, there was significant difference in distribution of HL promoter-514C/T genotype between CHD group and non-CHD group (χ2=15.851，P=0.015); but there was no significant difference in female group (χ2=0.249，P=0.969); Compared with LIPC-514-C/T CC male inpatients, there was significant increase in level of high density lipoprotein cholesterol [(34.6±8.9)mg/dl vs. (38.9±10.2)mg/dl, P=0.02] in CT/TT male inpatients. Conclusion: Hepatic lipase promoter-514C/T polymorphism has certain influence on levels of blood lipids in patients with coronary heart disease.

OBJECTIVE: To analyze the clinical manifestations, diagnosis, therapy and prognosis of Langerhans cell histiocytosis (LCH) of the temporal bone in children. METHOD: Seven children with LCH of the temporal bone n our hospital were retrospectively summed up from April 2009 to April 2014. The patients were followed up 1-5 years, their clinical manifestations, imaging findings, diagnosis, therapy and prognosis were studied. Correlation between clinical classifications and prognosis was also analyzed. RESULT: Among the 7 patients, 4 were boys and 3 were girls. 5 cases belonged to the single system group and 2 cases belonged to the multisystem group. The most common clinical characters were temporal tumor, otorrhea, otalgia, hearing loss and granulation of external auditory canal. CT of the temporal bones showed extensive osteolytic destructions with diffuse soft tissure density, without border sclerotization. The cases were. received different therapies. Followed up for 1-5 years, 4 cases were regressive, 1 case kept stable, while 2 cases showed progressive. The two boys then received standard treatment combined steroids with vinblastine. The prognosis in the multisystem group was significantly different from the single system group (P < 0.05). CONCLUSION The clinical manifestations of LCH vary a lot. The diagnosis is based on histological and immunophenotypic examination of lesion tissue. The main therapy includs surgery, chemotherapy and radiotherapy. The prognosis of the single system group is much better than the multisystem group.
