Objective To investigate the state of self-perceived burden (SPB) and depression and to explore the relationship between them for patients with chronic respiratory diseases.Methods 95 patients with chronic respiratory diseases were investigated by the Self-Perceived Burden Scale (SPBS) and Self-Rating Depression Scale (SDS).Results The average score of SPBS was (33.64±10.23) points,which was at the middle level,90.5％ of patients showed different levels of burden,and 34.7％ of patients were at the high level.The average score of SDS was (50.23±11.93),the index was 0.63,which was at the middle to high level,74.7％ of patients showed different levels of depression,and 33.7％ of patients were at the high level.There was a positive conrelation between SPB and depression.Conclusions Patients with chronic respiratory diseases had obvious SPB and depression,and there was a close relationship between them.With chronic respiratory diseases breaking out repeatedly and more severe year by year,most patients have high level of burden and negative emotions.Nurses should take proper measures and psychological interventions to help patients face to the diseases optimistically,and to improve patients' emotion state and enhance their physical and mental health.

The paper discusses whether to maintain nonhealthy foetus,the bearing control of patients with hereditary diseases,the aim to apply the technique to distinguish foetus' sex and personal morals and social ethical problems for health staff to do that,points out that the technique can be applied only to check hereditary diseases as to be benefit to bearing good child and arising people's quality ,and the techique should be controlled properly as not to serve for feudal ethic.

Ovarian cancer is highly lethal despite multiple therapies, and new therapies are therefore needed.Retinoids are potential anticancer drugs that can promote apoptosis,inhibit growth and induce differentiation in cancer cells,and all these functions are regulated by the expression of retinoid receptors.Herein the recent researches on the expression of retinoid receptors in ovarian cancer are reviewed.

With the wide application of Chinese herbal medicine, herb-drug interaction (HDI) has become increasingly prominent. Metabolic enzymes and transporters are the main targets of HDI, because the changes in expression and function of enzymes and transporters can influence the disposition of drugs. Metabolic enzymes are responsible for the metabolic clearance of drugs, including cytochrome P450 (CYP), UDP-glucuronyl transferase (UGT) and sulfotransferases (SULT); transporters widely expressed in the intestine, kidney, liver and brain are involved in the oral absorption, distribution and excretion of drugs. Pueraria, ginkgo, ginseng, St. John's wort and other Chinese herbal medicine often induce a HDI because those herbal medicines combined with chemical medicine are widely used in clinic. The components of herb medicines mentioned above are prone to interact with enzymes and transporters, which often induce a HDI. This paper reviews the advances in the study of enzymes and transporters-mediated pharmacokinetic mechanism of HDI.

Objective To study the effects of miR-130b on the neuronal migration in the developing embryonic mice cortex.Methods Pregnancy E15.5 mice were selected and plasmid of miR-130b was injected into the lateral ventricle of the embryonic brain.Two days after eletroporation,murine embryos were collected and cut into frozon coronal slices,then surveyed the neuronal migration under the fluorescence microscope.Results The neuronal migration rates were higher in miR-130b overexpression embryonic cortex,of which 75.1％ eletroporated neurons migrated into MZ,compared with the 22.1％ in control group.On the contrary,only 7.9％ eletroporated neurons stayed in the VZ/ SVZ in the experimental group,compared with the 69.3％ in control group.Conclusions miR-130b accelerates the neuronal migration in the developing embryonic mice cortex,its regulational role is worth studying.

Objective To investigate the expression of Alzheimer′s disease(AD) patients with serum CRP,IL-6,and analyze its clinical significance.Methods The clinical data of 85 patients with AD (AD group)treated in our hospital from March 2015 to June 2016 were retrospectively analyzed,and the data of 85 healthy adults were selected as control group.The differences of serum CRP,IL-6 levels,the mini mental state rating scale(MMSE) and the daily living ability rating scale(BI) score of the two groups were observed,and the correlation between CRP,IL-6 and MMSE and BI scores in patients with AD was analyzed.Results The levels of CRP and IL-6 in the AD group were significantly higher than those in the control group,the difference was statistically significant(P<0.05);The scores of directional function,instantaneous memory,attention and computational power were significantly lower in the AD group than those in the control group,the difference was statistically significant(P<0.05);The daily living ability scores of patients in AD group were lower than those in the control group,such as eating,bathing and dressing,and the difference was statistically significant(P<0.05);Serum CRP and IL-6 levels in patients with AD were negative correlation with MMSE and BI scores(P<0.05).Conclusion The levels of CRP and IL-6 in serum of patients with AD are high,and are closely related to the patients′ mental symptoms and daily living ability.

The control system of the French standard mobile BSL-3 is introduced.The working mode and opening or closing sequence is analyzed.The power safety design,the pressure ladder control using transducer and temperature control method are especially introduced in detail.Advanced control technique is summarized and some defects used in China are provided.Technical support is provided for the using and maintaining of the lab.

The main functions of modern Clinical Engineer(CE) is discussed. By combining experience of clinical engineering in developed country with clinical practice in our country, the work character problem of clinical engineering was proposed. According to the reality of equipment management and operation, the function of CE is not only to ensure medical equipment to run normally but also estimate the value of equipment in before buying or abandoning, PSS and technology study. Through the efforts of CE, the main functions of equipment can be made the best, medical therapy and new method research is more efficient.

Alzheimer's disease (AD) is the most common type of dementi a.PET probes can specifically detect the in vivo amyloid β peptide(Aβ) and Tau protein in AD inpatients' brain.The application of PET probes in AD is important for its early diagnosis and early intervention.US FDA has approved three PET probes for Aβ imaging while probes for Tau are still under research and development.This review summarizes current development of Aβ and Tau PET probes used for AD.
