OBJECTIVE To investigate the relationship between state trait anxiety and behavioral status in patients with sudden deafness. METHODS From April 2015 to June 2016, 140 cases of hospitalized patients with sudden hearing loss were selected as the observation group, and 140 healthy volunteers in our hospital for medical examination were selected as the control group. Average data, state trait anxiety, quality of life, and behavior survey were investigated in the two groups and correlation analysis was conducted. RESULTS The state trait anxiety score of the observation group was 51.20±4.19 points, and the control group was 34.40±3.49 points, and the state trait anxiety score of the observation group was significantly higher than that of the control group(t=12.949, P<0.05). The scores of physical, compulsive, interpersonal sensitivity, hostility and depression in the observation group were significantly higher than those in the control group(P<0.05). The problem solving and help scores in the observation group were significantly lower than that of the control group, while the fantasy and self accusation scores was significantly higher than that of the control group(P<0.05). In the observation group, Pearson correlation analysis shows anxiety scores were significantly correlated to the dimensions scores of quality of life, fantasy and self accusation scores(P<0.05), and were significantly negative correlated to the problem solving and help scores (P<0.05). CONCLUSION The patients with sudden deafness is accompanied by state trait anxiety and fantasy, self accusation and other bad behavior, it can seriously affect the patient's quality of life and form vicious circle, so the nursing intervention should be strengthened in clinical practice.

Objective: To study the effect of levosimendan treatment in patients of dilated cardiomyopathy (DCM) with different heart fraction. Methods: A total of 145 DCM patients were enrolled, based on left ventricular ejection fraction (LVEF), the patients were divided into 3 groups: Mild heart failure (HF) group, the patients with LVEF≤45%,n=15, Moderate HF group, LVEF≤40%,n=58 and Severe HF group, LVEF≤30%,n=72. LVEF, left atrial diameter (LAD), left ventricular end-diastolic diameter (LVEDD) and blood levels of BNP were examined and compared at prior and 7 days after levosimendan treatment respectively. Results: Compared with prior treatment, fater7 days of levosimendan medication, LVEF was elevated at certain degree in all 3 groups, while the statistic improvement was only found in Severe HF group (26.06±3.59) % vs (24.79±2.81) %,P<0.05; LAD and LVEDD had no obvious changes with levosimendan medication in all 3 groups,P>0.05. After levosimendan treatment, blood levels of BNP were decreased in all 3 groups as in Mild HF group (604.80±631.87) pg/ml vs (1252.17±1435.39) pg/ml, Moderate HF group (2369.78±2478.59) pg/ml vs (3206.90±2677.15) pg/ml and Severe HF group (4879.63±5302.42) pg/ml vs (6004.46±5041.59) pg/ml, allP<0.05. The differences of BNP level between prior and after levosimendan treatment, the ratio for BNP reduction were similar among 3 groups, allP>0.05. Conclusion: Levosimendan may, in short term, improve the cardiac function in DCM patients with mild, moderate and severe HF with similar degree; while it could not really change the cardiac structure.

Since the 1990s, studies on intemet addiction and mobile phone addiction have been concerned.Of which, internet addiction refers to internet surfing via personal computers, and mobile phone addiction is usually set within the phone calls and sending short message.In recent years, the time and frequency people using mobile phones have been increasing rapidly with the popularity of smart phone and the development of mobile Internet.Some severe cases show an excessive use of mobile phone, even dependent or addictive symptoms.These results in a variety of physical, psychological and social problems of the individuals.However, today's mobile phone dependence or addiction is beyond the scope of calling and texting, but more on the use of the network function.So it needs to redefine this behavior addiction and its criteria by combining both internet addiction and cell phone addiction.It is named as mobile internet addiction.The definition would help to study the mechanism of the development of mobile internet addiction, and provide theoretical foundations for developing effective intervention strategies.

BACKGROUND:Based on the blood and urine biochemical changes in different intensities and types of exercise, this research describes the impact of exercise on bone metabolism. Meantime, these biochemical indexes also show a method of marking physiological differences of certain individuals, and also reflect the impact of exercise on bone. These can be regarded as a monitoring index of bone growth and metabolism. OBJECTIVE:To study exercise effect from the biochemical indicators in bone metebolism, and make a further discussion about its influence on bone formation and bone resorption. METHODS:Databases of CNKI and PubMed were retrieved by computer with key words of “exercise; bone metabolism; biochemical indicators” in Chinese and English, respectively, by screening titles and abstracts to search papers related to exercise effects on the blood and urine biochemical indicators. Totaly 236 papers were initialy found, and only 38 papers were included in result analysis. RESULTS AND CONCLUSION: Low-intensity exercise shows less effect on the bone, but excessive exercise is harmful to the bone that can cause stress fractures. What’s worse, it causes a lack of female hormone and reduce bone mass. Exercise can alter the blood and urine biochemical indicators in aspects of types of exercise and intensities. Only the exercise at appropriate intensity makes positive effects on bone formation and resorption, and assists bone mineral density and bone biomechanical indicators to develop exercise prescription and arrange rehabilitation exercises. MechanismS of bone turnover need further discussion at the celular level.

Objective To evaluate the protective effect of epigallocatechin gallate (EGCG) against interleukin (IL)-17-induced injury to keratinocytes,and to explore its mechanism.Methods Some cultured HaCaT cells were divided into 3 groups to be treated with IL-17 alone at concentrations of 50,70,90 μg/L,respectively,with those receiving no treatment as the blank control group.Some HaCaT cells were divided into 5 groups:IL-17 group treated with 90 μg/L IL-17 alone,IL-17 + EGCG group treated with 90 μg/L IL-17 and 60 μmol/L EGCG,IL-17 + SP600125 group treated with 90 μg/L IL-17 and SP600125 (a JAK signaling pathway inhibitor),IL-17+ EGCG + anisomycin group treated with 90μg/L IL-17,60xmol/L EGCG and anisomycin (a Janus kinase signaling pathway activator),and blank control group receiving no treatment.After different durations of treatment,CCK-8 assay was performed to evaluate cellular proliferative activity,flow cytometry to detect cell apoptosis,enzyme-linked immunosorbent assay (ELISA) to measure expression levels of IL-6,IL-23 and IL-8,and Western-blot analysis to determine protein expressions of c-Jun N-terminal kinase (JNK) and phosphorylated JNK (P-JNK).Results IL-17 promoted cellular proliferation of HaCaT cells,and the proliferation rate,which was correlated with the concentration of IL-17,reached the maximum in the 90-μg/L IL-17 group (P ＜ 0.05).EGCG at 60 μmol/L significantly inhibited cellular proliferation of,promoted apoptosis in,and reduced IL-6,IL-23 and IL-8 expressions in,HaCaT cells induced by 90 μg/L IL-17 (all P ＜ 0.05).Compared with the IL-17 group,the IL-17 + EGCG group and IL-17 + SP600125 group both showed significantly decreased P-JNK expression,cell proliferation rate and IL-6,IL-23 and IL-8 expression levels (all P ＜ 0.05).However,compared with the IL-17 + EGCG group,the IL-17 + EGCG + anisomycin group showed significantly increased protein expression of P-JNK,cell proliferation rate and IL-6,IL-23 and IL-8 expression levels (all P ＜ 0.05).Conclusion EGCG protected against IL-17-induced injury to HaCaT cells,such as abnormal cell proliferation,apoptosis and inflammatory response,likely by inhibiting the JNK signaling pathway.

Objective To investigate the effect of the exogenous fragile hisdidine triad(FHIT) gene on the proliferation and the apoptosis of cutaneous carcinoma cell line A431,and to explore the mechanism of tumor suppression by the FHIT gene.Methods The plasmids pcDNA3-FHIT and pcDNA3-vector were transfected into the cutaneous carcinoma cell line A431 without FHIT gene expression,and then the transfected cells were screened by G418 and the expression of FHIT was determined by the immunocytochemical staining technique.The effect of FHIT on the growth characteristics of cutaneous carcinoma cell line A431 was observed by MTT,colony forming test and flow cytometry.Results Stable FHIT gene expressing A431 cells were produced,the proliferation activity and colony forming capability of A431FHIT were suppressed,whereas the apoptosis was increased.All these differences between A431-FHIT cells and the two control groups of cutaneous carcinoma cells had statistical significance.Conclusion Transfecting the exogenous FHIT gene into cutaneous carcinoma cells line A431can suppress the proliferation of tumor cells,and can also induce apoptosis and cell cycle arrest.

Objective To evaluate effects of ursolic acid (UA) on interleukin?33 (IL?33) expression in HaCaT cells induced by interferon?γ(IFN?γ), and to explore their mechanism. Methods Some HaCaT cells were treated with UA at different concentrations(0, 0.1, 1, 5, 10, 20, 40 and 80μmol/L)for 24, 48 and 72 hours separately. Then, methyl thiazolyl tetrazolium(MTT)assay was conducted to evaluate cell proliferative activity. A cell model of inflammation was established by culture of HaCaT cells with the presence of 200μg/L IFN?γ. Some HaCaT cells were classified into several groups to be treated with IFN?γ(200μg/L)and UA(10 and 15μmol/L)alone or in combination (firstly treated with IFN?γ followed by UA treatment), and those receiving no treatment served as the blank control group. Reverse transcription PCR (RT?PCR) was performed to detect mRNA expressions of IL?6 and IL?33, and Western?blot analysis to measure IL?33 protein expression after 12?hour culture. The expressions of extracelluar signal?regulated kinase 1/2(ERK1/2)and phosphorylated ERK1/2(p?ERK1/2)were also measured by Western?blot analysis after 5?and 60?minute treatments with IFN?γand UA alone or in combination. Results MTT assay showed that the treatments with 5-20μmol/L UA for 24 hours had no effects on cell proliferative activity, while 40-80μmol/L UA could significantly inhibit it at 24, 48 and 72 hours (all P < 0.05). Thus, 10 and 15 μmol/L were chosen as the concentrations of UA for further study. After the treatment with 200μg/L IFN?γ, there was a significant increase in the expressions of IL?33 mRNA(0.812 ± 0.036 vs. 0.412 ± 0.021), IL?6 mRNA(0.947 ± 0.091 vs. 0.595 ± 0.030)and IL?33 protein(1.317 ± 0.119 vs. 0.147 ± 0.036)in HaCaT cells compared with the blank control group(all P<0.05). Compared with the IFN?γgroup, the IFN?γ+10?μmol/L UA group and IFN?γ+15?μmol/L UA group both showed significantly decreased expressions of IL?33 mRNA(0.447 ± 0.042 and 0.438 ± 0.028 respectively, both P<0.05), IL?6 mRNA(0.437 ± 0.099 and 0.350 ± 0.075 respectively, both P<0.05)and IL?33 protein(0.923 ± 0.058 and 0.564 ± 0.113 respectively, both P<0.05). There were no significant differences in IL?33 mRNA expression between the IFN?γ+10?or 15?μmol/L UA group and blank control group(P>0.05), while IL?33 protein expression was significantly lower in the IFN?γ+15?μmol/L UA group than in the IFN?γ+10?μmol/L UA group(P<0.05). The p?ERK1/2 protein expression significantly increased in HaCaT cells treated with IFN?γ for 5 and 60 minutes compared with the blank control group, but significantly decreased in the IFN?γ+15?μmol/L UA group compared with the IFN?γgroup(0.458 ± 0.053 vs. 0.941 ± 0.042 at 5 minutes, 0.302 ± 0.054 vs. 0.509 ± 0.032 at 60 minutes, both P < 0.05). However, no significant differences were observed in the total ERK1/2 protein expression between the IFN?γ+15?μmol/L UA group and IFN?γgroup at 5 or 60 minutes. Conclusion UA can suppress IL?33 expression in HaCaT cells induced by IFN?γ, likely by regulating expressions of the ERK signaling pathway?related proteins.
