Objective To observe the abnormality on behavioral ability of transgenic mice for HRX-EEN fusion gene.Methods Transgenic mice for HRX-EEN fusion gene(transgenic group,n=12)and C57/BL mice(control group,n=12)were tested in hidden platform training(day 1 to day 4)and probe trial testing(day 5)in Morris water maze in which ability of spatial learning and retention was assessed.Results In hidden platform training,the latencies of transgenic group were longer than those in control group,and significant differences were observed between the two groups for day 2,3 and 4(P

Objective To determine the effect of photochemotherapy on the expression of gelatinases. Methods Reverse transcription-polymerase chain reaction and gelatine zymography were employed to detect the effect of photochemotherapy on the expression and bioactivity of gelatinases at mRNA and protein levels respectively. Results Combination of ultraviolet A(UVA,0.8-2.0 J/cm2) and 8-methoxypsoralen(8-MOP,100 ng/mL) resulted in a decrease in the expression and bioactivity of gelatinases. Conclusion Photochemotherapy can inhibit the angiogenesis of endothelial cells through downregulating the expression and bioactivity of gelatinases.

Mycotic vaginitis is a common and frequently-occurring gynaecopathia and easy to attack repeatedly, so painful to patients. In this study, the authors observed the clinical efficacy of Sophora gel combined with Fluconazole capsules in treating mycotic vaginitis, in order to seek an effective method for treating mycotic vaginitis. Totally 85 patients with mycotic vaginitis treated in our hospital between December 2012 and July 2014 were randomly divided into the treatment group (43 patients) and the control group (42 patients). The treatment group was given vaginally Sophora gel (one piece every night for 14 days) and orally Fluconazole capsules (150 mg, once every three days, four times in total); The control group was only administered with Fluconazole capsules. The total efficacy, cure rate, recurrence rate and clinical symptom improvements of the two groups were observed. The results show that the total efficacy, the cure rate and the recurrence rate of the treatment group vs. the control group were respectively 97.7%, 90.7% and 2.6% vs. 83.3%, 71.4% and 20.0%, with statistical significance in their differences (P < 0.05). The treatment group showed reduced leucorrhea, pruritus vulvae disappearance and earlier mucosal hyperemia disappearance than the control group, with statistical significance in their differences (P < 0.05). In conclusion Sophora gel combined with Fluconazole capsules can improve antifungal activity of drugs, relieve clinical symptoms, shorten the course of disease, enhance the cure rate and reduce the recurrence rate; So this therapy can be widely applied in clinic.

Bone marrow mesenchymal stem cells (MSCs), multipotent stem cells, can replicate as undifferentiated cells and have the potential to differentiate into different lineages of mesenchymal tissues, including bone, cartilage,endothelial, neural, smooth muscle, skeletal myoblasts, and cardiac myocyte cells. The ischemia-induced death of cardiomyocytes results in scar formation and reduced contractility of the ventricle. Several preclinical and clinical studies have supported the notion that MSCs therapy may be used for cardiac regeneration.When transplanted into the infracted heart, MSCs prevent deleterious remodeling and improve recovery, but the mechanism is not clear. In this work,we review evidence and new prospects that support the use of MSCs in cardiomyoplasty.

Objective] To evaluate effect of health literacy intervention in occupational groups , explore suitable ways and provide suggestions for workplace health promotion . [ Methods ] In application of convenience sampling , Minhang District , Hongkou District and Qingpu District each selected 2 enterprises respectively according to their type , scale and location , setting one as intervention enterprise and the other as control .Then a six-month comprehensive intervention was conducted among intervention groups .Two hundred employees in each enterprise were randomly investigated before and after intervention to evaluate the effect . [ Results ] The overall health literacy level of participants in the intervention group rose from 16.7% to 33.4%, with improvement on the literacy levels of scientific view , infectious diseases prevention and treatment , chronic disease control and prevention and the three aspects of health literacy content ( P<0 .05 ) , while such improvement was not reflected in the control group , and health skill literacy, safety and first aid literacy declined (P <0.05). [Conclusion] Comprehensive intervention based on health needs could improve the level of health literacy of occupational groups . Intervention in future should focus on improving the literacy of chronic disease control and prevention and basic medical care in occupational population .

Objective To develop an early-warning indicator system of brucellosis outbreak. Methods The methods of literature review and expert discussion were used to formulate the initiatory framework and indicators, and then Delphi method was used to filter indicators, discuss the boundary of indicators and determine the weighting coefficient. Results The average length of service provided by experts who engaged in prevention and control of brucellosis was (25.10 ± 8.80) years and the positive coefficient of the consultant experts of the two-round results were 95% and 68%, respectively. Kendall coefficients were 0.35, 0.54 and X2R value were 81.31 and 285.27, respectively and P value was all less than 0.01. Five first-level indicators(the host animal, high-risk groups,social environment, index case and the level of previous disease) and 13 secondary indicators were selected to develop the early-warning indicator system of brucellosis outbreak. The weight coefficients of the five first-level indicators were 0.21, 0.22, 0.17, 0.21 and 0.19, respectively. Conclusions The early-waming indicator system of brucellosis outbreak is initially established. We propose to develop the early-warning programs according to local conditions and the indicator system.

When the glomerular mesangial cells of rats were cultured in vitro at high glucose concentration,the activity of extraeellular signal-regulated kinase(ERK),the expression of transforming growth factor-?_1(TGF-?_1)mRNA and the content of typeⅣcollagen in the supematant were higher than those at normal glucose concentration.These effects were inhibited by fluvastatin.The results showed that the activation of ERK signal transduction pathways appeared to play a role in the onset and progression of diabetic nephropathy. Furthermore,fluvastatin could protect the kidney by inhibiting ERK signal transduction pathway and TGF-?_1 expression.
