Objective: To study and analyze the influence of atorvastatin combined trimetazidine on levels of blood lipids,inflammatory factors and cardiac function in patients with coronary heart disease (CHD).Methods: A total of 128 CHD patients treated in our hospital from May 2015 to Oct 2016 were selected.According to random number table, they were randomly and equally divided into trimetazidine group (received trimetazidine based on routine treatment) and combined treatment group (received atorvastatin based on trimetazidine group).Both groups were treated for three months.Levels of blood lipids, inflammatory factors and cardiac function were measured and compared between two groups before and after treatment.Results: Compared with trimetazidine group after treatment, there were significant reductions in levels of triglyceride [(2.11±0.73) mmol/L vs.(1.83±0.77)mmol/L], total cholesterol [(5.14±0.96)mmol/L vs.(4.35±0.73)mmol/L], low density lipoprotein cholesterol [(2.35±0.68) mmol/L vs.(1.90±0.34) mmol/L], N terminal pro B type natriuretic peptide [(296.61±28.96) pg/ml vs.(187.53±32.63) pg/ml], fibrinogen [(4.44±0.34) g/L vs.(3.63±0.54) g/L] and high sensitive C reactive protein [(2.41±0.96) mg/L vs.(1.96±0.82) mg/L], left ventricular end-diastolic dimension [(59.25±6.17)mm vs.(48.43±4.28)mm] and left ventricular posterior wall thickness [(11.01±1.08)mm vs.(9.05±1.04)mm], and significant rise in level of high density lipoprotein cholesterol [(1.32±0.25)mmol/L vs.(1.47±0.38)mmol/L] and left ventricular ejection fraction [(41.28±7.04)% vs.(48.66±7.54)%] in combined treatment group, P<0.05 or <0.01.Conclusion: Atorvastatin combined trimetazidine can significantly improve blood lipid, inflammatory factor levels,cardiac function and cardiac structure in CHD patients.The therapeutic effect is significant, which is worth extending.

Objective To investigate the expression of nm23,integrin ? 5? 1 and VEGF in breast cancer(BC),and the effect of the expression on the development of BC. Methods The expression of nm23, integrin ? 5? 1 and VEGF in 51 patients with breast cancer were examined by immunohistochemistry,and their correlatios were ananlyzed. Results The low expression of nm23 in BC tissue was associated with lymph nodes metastasis. The low expression of integrin ? 5? 1 and the high expression of VEGF in BC tissues were associated with the lymph nodes metastasis and low differentiation of the tumor.The expression of nm23 and integrin ? 5? 1 in breast cancer tissues had positive correlation(P

Objective:To test the microtensile bonding strength between root canal wall and Bis-Core, and that between root canal wall and Chemil Superior glass-ionomer.Methods:10 human maxillary incisors extracted within one week were kept for another one week after root canal treatment and removeal of the crowns,each root was splited into two parts along with the long axis by Isomet saw, the bonding interface on one third of upside of root dentin smear layer was made with Diamond bur at a high-speed. Then Bis-Core and Chemil Superior glass-ionomer were put on root canal inner surface of each half part of the root respectively, samples with the size of 1.00 mm?1.00 mm were prepared by Isomet saw. Two samples in which bonding interface was perpendiculur to load were selected and fixed in Microtensile testing machine for bonding strength test. Results:Microtensile bonding strength(MPa) between Bis-Core and root canal inner wall and that between root canal inner wall and Chemil Superior glass-ionomer was 20.65?1.72 and 12.89?1.63 respectively(P

Objective:To observe the microstructure of interface between material and dentin after root canal rehabilitation. Methods:Three human maxillary incisors extracted within one week were used. After crowns being removed and received root canal treatment, they were used for the study. The root was split into two parts along the long axis, then the bonding interface was made with high speed diamond bur. Bis-Core and Chemil Superior glass-ionomer were stacked on root canal inner wall respectively and the teeth were split along with the long axis with Isomet saw, in order to expose bonding interface. The microstructure of bonding interface of the samples were analyzed by optical microscope and atomic force microscope(AFM). Results: AFM observation of the adhesive interface specimens showed that Chemil Superior glass-ionomer and teeth knitted together completely and no filling invaded into dentin tube. While the bonding interface between Bis-Core and dentin, dentin primer infiltrated into dentin tube and matrix around through the smear layer and colophony protruded. Conclusion:The observations reveal the extent of resin penetration into the dentinal tubules provides a very strong bonding. This is a fundamental cause of resin better bond to tooth.

Objective To establish a human umbilical artery EC-SMC co-culture model, and mimic the morphological and functional characteristics of human arterial wall, for further reseach of the pathological mechanism and therapy of atherosclerosis and imflammatory damage. Methods We secceeded in the primary culture of human umbilical artery endothelial cells (HUAEC) and human umbilical artery smooth muscle cells (HUASMC) by collagenase perfusion digestion and tissue planting, respectively. HUASMCs were incubated in a medium with ascorbic acid at the concentration greater than 50 μg/mL to produce collagen, which was considered as the extracellular matrix for ECs. Then HUAECs were seeded directly upon HUASMCs in a saturate density for sufficient direct physical interaction between ECs and SMCs. The morphological characteristic of EC-SMC co-culture was identified by immunofluorescence staining, and the function of EC-SMC co-culture was identified by Dil-Ac-LDL uptake test. Results The morphological identification showed that the entire surface of HUASMCs was covered by a confluent monolayer confluent monolayer, which indicated that the model had simulated the morphological characteristic of human arterial wall. The results of Dil-Ac-LDL uptake test showed that there was a fluorescent signal in HUAECs. Compared with EC monoculture, the Dil-Ac-LDL uptake of HUAECs was increased significantly in the co-culture system. All the reseach results indicated that there was an interaction between HUAECs and HUASMCs in the co-culture system. Conclusions In the present study, human umbilical artery EC-SMC co-culture model was constructed successfully, which could mimic the morphological characteristic and basic functions of human arterial wall.

Inflammatory Bowel Disease(IBD) is concerned with heredity,dysimmunity,environment and others,its characterized by chronic or relapsing inflammation within the gastrointestinal.IBD including two independent disease ulcerative colitis and crohn′s disease.In recent years with the incidence of IBD increased year by year,more women in reproductive age facing drug treatment.This article elucidated the effect of IBD and its treatment on perinatal.

It is related to the treatment effect of the disease and the quality of life of the patient that perioperative management of ruptured esophagogastric varices bleeding with portal hypertension.According to the individual characteristics of the patient combined with the experience of the surgeons,the key points of individualized treatment consist of accurate and comprehensive preoperative preparation,fine post-operative treatment,and the changes of pre-and post-operative hemodynamics of portal vein system to choose a reasonable procedure,meanwhile,the delicate postoperative managements can improve the surgical effect of portal hypertension.

Natriuretic factors,include cardionatrin(CN)and digoxin-like immunoreac-tive substances(DLIS),were important humoral factors relating to ascites formation inliver cirrhosis.An observation was made on the levels of plasma CN,DLIS,angiotensinⅡ, aldosterone and serum and urine sodium contents berore and after ascites extinction in40 cirrhotic patients.The results showed that the plasma levels of CN and DLIS had dis-tinct changes before and after ascites extinction and their changes were parallel with theactivity of renin-angiotensin-aldosterone system.These facts suggested that CN and DLIShad certain relation with ascites formation in liver cirrhosis.
