Viral myocarditis can cause severe myocardial injury and even acute heart failure, then evolve into dilated cardiomyopathy, known as inflammatory cardiomyopathy. Immune reaction plays a key role in the transformation from viral myocarditis into dilated cardiomyopathy, including virus RNA continuous replication,immune-mediated injury, cellular apoptosis, other cellular immune response , myocardial antibodies and other humoral immune response. In the clinical treatment, besides anti-heart failure and cardiac nutrition, the use of ribavirin, α1-receptor blockers, β-receptor blockers, calcium channel blockers, angiotensin converting enzyme inhibitors and spironolactone should be emphasized.

Objective To understand the learning needs of nursing students for nursing English in senior high vocational school.Methods A survey was carried out among 982 three-year nursing students in grade 2007-2009 in Cangzhou medical college by questionnaire.The data collected were analyzed using descriptive statistics with SPSS 17.0.Results Most students (93.0％) believed that nursing English was important and had a strong desire for most English skills,especially speaking and listening ability.They (90.7％) expected nursing teachers to take charge of or participate in teaching work and some students (30.6％) were dissatisfied with teaching material.They depended on teachers' instruction and preferred learning in real situations.Conclusions Nursing students in senior high vocational school have strong needs for nursing English,but there is a gap between current teaching situation and learning needs,which the course designers and teachers should take into full consideration in order to make the teaching more effective.

Objective To summarize the experience of nursing cooperation in endoscopic sinus surgery for low temperature plasma radiofrequency ablation of skull base tumor, and to explore the safety and feasibility of this technique. Methods A total of 69 patients with skull base tumor were treated with low temperature plasma radio frequency technology to remove skull base tumor. Results Totally 62 cases of skull base tumors completed total resection in low temperature plasma radiofrequency ablation, 7 cases gained subtotal resection. The operation demonstrated superior advantage of less bleeding, short operation time, less postoperative pain and no adverse events. Conclusions The skull base tumor resection for patients with skull base tumors with low-temperature plasma radiofrequency possesses the advantages of short operation time, less bleeding and thermal damage to the surrounding tissues, besides it can reduce the postoperative discomfort, shorten hospitalization time and reduce the occurrence of nursing adverse events.

AIM: To investigate whether carnosine can inhibit cataract formation and protect Na+-K+ATPase against inactivation induced by a glucocorticoid.METHODS: Two hundred and twenty clear lenses cultured in vitro were randomly divided into five groups: control group (DMEM), steroid group (DMEM+Dexamethason 10μmol/L),lower concentration carnosine-treated group (DMEM+Dexamethason 10μ mol/L+Carnosine 2mmol/L), higher concentration carnosine-treated group (DMEM+Dexamethason 10μmol /L+Carnosine 5mmol/L) and carnosine group (DMEM + Carnosine 5mmol/L). Progression of cataract formation was evaluated daily using a dissecting microscope. On 1, 3, 5 and 7d, 10lenses of every group were homogenized and the activity of Na+-K+ATPase was measured by using spectrophotometer.RESULTS: During the incubation, mistlike opacity was observed in the lenses of the control group and carnosine group,but in the steroid group appeared dense nuclear opacity, while both two carnosine-treated groups came out visible demarcation between nuclear and cortical regions on 7d. A decrease in the activity of Na+-K+ATPase was found in the lens of the steroid group. On 3, 5, 7d, Na+-K+ATPase activity decreased 22.34% (P=0.002),47.98% (P＜0.001),75.37% (P＜0.001) compared with that at 1d, respectively. In the carnosine group,the activity of Na+-K+ATPase remained at the level of the control throughout the 7-d incubation, indicating that carnosine itself did not interfere with the original lens enzyme activity. In the lower concentration carnosine-treated group, on 3, 5, 7d,the activity of Na+-K+ATPase increased 10.8% (P＜0.05),44.6% (P＜0.01), 57.4% (P＜0.01) of control activity, respectively. In the higher concentration carnosine-treated group, on 3, 5, 7d, the activity of Na+-K+ATPase increased 11.3% (P＜0.05), 45.7% (P＜0.01), 57.6% (P＜0.01) of control activity,respectively. The activity of Na+-K+ATPase in both two carnosine-treated groups were only 6.7% and 6.5% lower than that of the control group after 7-d incubation. After the 7-d incubation, the Na+-K+ATPase activity of the lenses in the steroid group decreased significantly compared with carnosine-treated groups (P＜0.01).CONCLUSION: Carnosine prevents the cataract formation induced by a glucocorticoid, and significantly inhibits the inactivation of Na+-K+ATPase induced by a glucocorticoid.

Objective:To investigate the infloence of RNA interference targeting P13K p85α on the invasion and metastasis of colorectal cancer cells. Methods:Foor shRNA vectors and one negative control vector were designed and stably transfected into LoVo cells. Western blotting analysis was used to screen for the groop which had the highest inhibitory rate; the cells were sobjected to woond closore assay and transwell assay to determine the migration of LoVo cells after stable transfection. Results: Western blotting analysis showed that cells transfected with shRNA/324 vector had the strongest inhibition of P13K p85α protein, with the inhibition rate being 77% , and cells in this groop were osed for woond closore assay and transwell assay. Wound cloaore assay showed that the healing ability of P13K p85α-depleted cells was significantly lower than that of the control cells (P<0.05). Transwell assay showed that the cells passing the polycsrhonate membranes was significantly less in P13K p85α-knockdown cells than in the control cells (P<0.05). Conclusion:Depletion of P13K p85α protein can obvioosly inhibit the migration of LoVo cells. P13K p85α may be a new therapeotic target for treatment of colorectal cancer metastasis.

Objective: To assess the synergistic anti-inflammatory effect of sodium ferulate (SF) and kushenin, i.e. oxymatrine (OMT). Methods: The anti-inflammatory effect of the combination of SF and OMT was evaluated on xylene-induced murine ear edema model, carrageenin-induced rat paw edema model, and rat tampon-induced granuloma model in vivo. In vitro, the effect of SF and OMT on the nitric oxide (NO) production induced by LPS was observed on RAW264.7 cells. The content of NO in the supernatant was detected with Griess reagent. Results: When SF was used in combination with OMT, the edema induced by xylene and carrageenin was markedly inhibited, the weight of granuloma caused by tampon was also reduced in the high dose group, and the inhibition rate was more considerable by combined treatment than those by SF or OMT alone. In vitro, the NO production induced by LPS was depressed by combined treatment, and a synergistic anti-inflammatory effect was observed. Conclusion: The present study demonstrate that the combination of SF and OMT could exert conspicuous synergistic anti-inflammatory effect, and the mechanism may be related to the inhibited effect of NO production in inflammatory factors induced by LPS.
