Objective To explore the influence of long -term oral hydroxychloroquine on the blood lipids and left ventricular function in patients with systemic lupus erythematosus (SLE).Methods A total of 110 patients with SLE,who treated in our hospital from January 2012 to December 2013,were selected as the research subjects. They were divided into study group (n =55 )and control group (n =55 )according to the random number table method.The control group received conventional drug treatment,while the study group was orally given hydroxychloroquine on the basis of the control group therapy.The course of treatment was 18 months for the two groups.Then,the changes of blood lipids,left ventricular structure and function indexes before and 6,12,18 months after treatment were observed.Results The levels of TG[(1.7 ±0.3)mmol/L,(1.6 ±0.3)mmol/L,(1.2 ±0.2)mmol/L],TC[(4.5 ± 0.5)mmol/L,(4.3 ±0.4)mmol/L,(4.0 ±0.4)mmol/L],HDL -C[(1.4 ±0.4)mmol/L,(1.5 ±0.3)mmol/L, (1.6 ±0.3)mmol/L],LDL -C[(2.8 ±0.5)mmol/L,(2.3 ±0.4)mmol/L,(2.0 ±0.3)mmol/L],LVEDD[(40.3 ± 3.3)mm,(39.4 ±3.0)mm,(38.5 ±2.9)mm],LVESD[(29.4 ±2.6)mm,(28.3 ±2.3)mm,(26.7 ±3.0)mm], LVST[(9.7 ±0.4)mm,(9.5 ±0.6)mm,(9.5 ±0.5)mm],LVPWT[(10.2 ±0.4)mm,(10.0 ±0.3)mm,(9.8 ± 0.4)mm],FS[(31.4 ±6.8)%,(32.6 ±7.0)%,(32.7 ±7.7)%),LVEF[(60.4 ±5.4)%,(60.7 ±5.7)%, (61.4 ±5.6)%],E /A[(0.8 ±0.2),(0.9 ±0.3),(1.1 ±0.3)]in the study group 6,12,18 months after treat-ment were significantly better than before treatment[(2.0 ±0.4)mmol/L,(4.8 ±0.8)mmol/L,(1.1 ±0.3)mmol/L, (3.4 ±0.4)mmol/L,(42.4 ±3.8)mm,(30.7 ±3.5)mm,(9.9 ±0.6)mm,(11.2 ±0.5)mm,(30.1 ±5.7)%, (55.8 ±4.6)%,(0.7 ±0.1 )],and which were all better than those in the control group,the differences were statistically significant(tTG =2.529,2.828,2.735;tTC =3.609,3.122,3.317;tHDL -C =3.651,3.419,3.733;tLDL -C =2.008,2.144,2.338;tLVEDD =8.933,8.347,8.282;tLVESD =6.445,6.628,6.594;tLVPWT =3.015,3.331,3.905;tLVST =4.571,4.583,4.861;tLVEF =11.021,11.328,10.163;tFS =7.915,8.048,8.253;tE /A =1.886,1.769,1.537;all P <0.05).Conclusion Long -term oral hydroxychloroquine in the treatment of patients with SLE not only can improve the blood lipids situation,but also is good for the left ventricular structure and function,which may avoid the occurrence of vascular events,and it is worthy of clinical promotion.

Evidence based medicine is not quite the same as traditional medicine, as the former stresses the combination of evidence and doctors experience, failure to achieve which will be disadvantageous to patients. In recent years, evidence based medicine has been growing silently in China. At present the ideology of evidence based medicine is being widely applied to the treatment of cardiovascular disease, including hypertension, arrhythmia, heart failure, myocardial infarction, etc. and the regulation of fat metabolism. Some medications harmful to patients have been discarded and curative effects have been improved. Of course, there are still some shortcomings. Yet evidence based medicine has also exerted an effect on people in the medical circle and the making of medical decisions.

SUMO (small ubiquitin-related modifier) is involved in the post-translational modifications of proteins,and this process is referred to as SUMOylation.SUMOylation plays an important role in the regulation of cellular activities such as strengthening the stability of the protein,nucleocytoplasmic transport,DNA repair,DNA replication,mitotic and meiotic chromosome behavior,et al.SUMOylation is a dynamic process and can be reversed by SUMO-specific proteases (SENP).Once the balance between SUMOylation and de-SUMOylation is broken,there will be an aberrant expression of SUMO or SENPs in cells to happen,which may lead to the tumor occturtrence.

Objective To investigate the therapeutic effect of transplantation of limbal epithelial cells and decellularized porcine cornea construct in rabbits with corneal alkali burn.Methods Allogeneic rabbit limbal epithelial cells were cultured and identified.Porcine cornea scaffold was fabricated by decellularization.The LECs-DPC construct was cultured and transplanted to the alkali-burned corneal surface of rabbits(4month follow-up).Results Immunocytochemistry and RT-PCR analyses revealed the presence of ABCG2 positive limbal stem cells.A general view showed the corneas were clear and vessel-free postoperatively.HE and Masson Trichrome staining results indicated the epithelial stratification,fewer cellular infiltration,DPC' integration into host corneal tissues,and more regular collagen configuration.Transmission electron microscopy exhibited formation of desmosomes and microvilli.Conclusion Allogeneic limbal epithelial cells transplantation using DPC as a carrier can restore corneal clarity after alkali burn in a rabbit model.

Objective Depression is a mood disorder that causes a persistent feeling of sadness,with high morbidity rates and great social impairment.Increasingly studies show the abnormalities of brain networks.We summarized the results of resting state functional magnetic resonance imaging study of depression,and demonstrated the neural loops mechanism from neuroimaing perspective.Methods The key words depression, resting state and network were searched in PubMed,CNKI and Wan Fang databases from January 2000 to December 2014.The nodes of depression related network and the alterations of cortex resting-state networks were summarized.Results 24 studies focusing on resting state network of depression were identified.40 studies based on ROI (region of interest) analysis,which included amygdala,frontal lobe,pregenual anterior cingulate cortex and cerebellum.The functional connectivity of ROIs were calculated and compared between groups.8 studies based on ICA (independent component analysis),the resting state networks were extracted and compared between groups.Two based on graph theory,the functional connectivity of whole brain were analyzed and compared.Conclusion There are abnormalities of functional connectivity among limbic system-thalamus-frontal cortex,and the changes of functional connectivity were associated with clinical symptom and drug efficacy of depression.

Tuberous sclerosis complex (TSC) is a genetic disorder affecting every organ system, but disease manifestations vary significantly among affected individuals.The diverse and varied presentations and progression can be life-threatening with significant impact on quality of life.The 2012 international Tuberous Sclerosis Complex Consensus Recommendations provide an evidence-based, standardized approach for optimal clinical care provided for individuals with TSC.

0.05). 3)ALP assay showed that the 7th,14th and 28th day of bBMP implantation, the ALP activities of bBMP in implantation groups were relatively higher than that of the control group (P0.05). 4)Histologically,after the 7th day implantation, a large quantity of mesenchymal cells differentiated with active chondrogenesis. The 14th day later, a large amount of cartilage and woven bone formed, and laminar bone and bone marrow were seen on day 28 after implantation. Conclusion The bBMP possesses active bone induction properties even after 10 years storage in 4℃ . The low-level antibodies of the recipient mice can be detected after implanted with bBMP, but the bone inducing activities are not affected. This may be a reference data for purification and clinical application of native BMP.

Objective To examine the segmental bone defects healing by ? TCP/rhBMP 2 composites with different degradation rate and discuss the relationship between osteogenesis and degradation of ? TCP in vivo. Methods Three kinds of ? tricalcium phosphate(? TCP) with different degradation rate (? TCP1-3) were prepared by means of different techniques. ? TCP/rhBMP 2 composites with different degradation rate(? TCP1/rhBMP 2 and ? TCP2/rhBMP 2)were obtained by combining ? TCP1, ? TCP2 with recombinant human bone morphogenetic protein 2(rhBMP 2), respectively. ? TCP1/rhBMP 2, ? TCP2/rhBMP 2, ? TCP1, ? TCP2 and ? TCP3 were used to repair 15 mm radial segmental defects in 81 Chinese rabbits. When the samples were harvested in 4, 8, 16 and 24 weeks after surgery, a series of examination were carried out, including the roentgenographical, histomorphological, biomechanical and computerized graphical analysis, energy dispersion analysis X ray (EDAX), and measurements of inorganic contents. Results Roentgenographically and histologically, all of the defects that had been treated with implants exhibited new bone formation, increasing with time. The quantity and rate of new bone formation in ? TCP1/rhBMP 2 group and ? TCP2/rhBMP 2 group were higher than those in group of ? TCP alone. The ability of new bone formation in ? TCP1/rhBMP 2 group was strongest. At 24 weeks the defects in ? TCP1/rhBMP 2 group were bridged with the appearance of marrow cavities, the inorganic contents and ratio of calcium to phosphate and biomechanical property in implants approached to those of normal bone. Although degradation occurred to some extent in ? TCP alone the degradation were faster in ? TCP/rhBMP 2 composites. At 24 weeks the degradation rate in ? TCP1/rhBMP 2 group and ? TCP2/rhBMP 2 group were 97.4%and 73.4%, respectively. The defects in blank controls were repaired only by fibrous tissue at 24 weeks. Conclusion ? TCP/rhBMP 2 composites with different degradation rate could repair segmental bone defects, and osteogenesis could accelerate the degradation of ? TCP in vivo.

Objective To investigate the effect of a kind of tissue engineered bone implants on healing of segmental bone defects. Methods A 15 mm bone defect experimental model at the right radius of New Zealand white rabbit was made. 24 animals of this model were divided into three groups at random. PLGA scaffords loaded with 5 mg BMP and about 1?106 BMSCs were implanted in Group 1(n=10); PLGA scaffords loaded with 2.5 mg BMP and about 1?106 BMSCs were implanted in Group 2(n=7); PLGA scaffords loaded with 1 mg BMP and about 1?106 BMSCs were implanted in Group 3(n=7). The osteogenesis at the defect area was observed by regular roentgenography and X-ray analysis, histological changes at the bone defects at 4th, 8th, 12th weeks after operation were studied and the new bone formation was measured by image analysis. Biomechanical analysis was done 12 weeks after operation. Results A large quantity of callus was found in all the 3 groups 4 weeks after repair. At the 12th week, the complete bone healing rate was 7/8, 3/5, 3/5, respectively in Group 1, 2 and 3. Group 1 had the largest quantity of new bone measured by histopathological study and X-ray analysis, and at the 12th week, the medullary cavity in this group became united. The compress stiffness, torsion stiffness and the maximal load in Group 1 were better than those in other groups. Conclusion The tissue engineered bone contructed by PLGA scaffords that are loaded with 5 mg BMP and BMSCs is capable of repairing segmental bone defects.
