[Objective] To discuss the nursing to the common complications in perioperational period of lung cancer treated with ultrasonic guidance transdermal radiofrequency ablation(RFA). [Method] 12 cases of peripheral lung cancer treated with ultrasonic guidance transdermal RFA, took active mental nursing, closely cooperated in operation, strictly observed the disease condition after operation, had good nursing of perioperational period, and were strengthened on observation of complications and prevention. [Result] 12 cases had smooth operation, part of them had pain at puncture spot, fever, little aerothorax and hydrops, with blood in sputum at cough, and were relieved timely with active observation and clinical nursing, without other severe complications, final y they were discharged from hospital upon recovery, without death in perioperational period. [Conclusion] The ultrasonic guidance RFA is a safe and effective method to treat peripheral lung cancer with little invasion; the nursing point is to closely observe disease condition before and after operation, and do wel general nursing.

The practice of catastrophic disease insurance in China is an important attempt to decentralize administration and build a service-oriented government.Under the developing model of governmental service purchase, an efficient supervision is the key part of ensuring and upgrading the effectiveness of catastrophic disease insurance system.Starting from theoretical analysis on the service outsourcing of the operating mechanism and its features, this paper discusses the legal attributes and supervision responsibilities of catastrophic disease insurance in China, and then explores the main problems of the current regulation system in view of regulatory responsibilities, supervisory subjects, as well as supervision contents, methods and means, etc.For these problems, it's urgent to re-draw a definite boundary of government responsibilities for the system, determine the supervisory subject as human resources and social security departments, and develop unified standards at provincial level for the bidding process.It's also necessary to establish a scientific performance evaluation system, promote multi-sector joint supervision among different government sectors involved, practice information sharing and means of digital regulation, in order to achieve efficient supervision of catastrophic disease insurance in China.

Objective To observe and study the variation ofinterleukin (IL),trace elements and adhesion molecule in allergic rhinitis patients.Methods Forty-seven allergic rhinitis patients who were diagnosed from March 2011 to March 2013 were selected as observation group.Among the total,intermittence was 27 patients,continuity was 20 patients,mild was 15 patients,moderate was 19 patients,severe was 13 patients.Forty-seven healthy person at the same time were selected as control group.The level of IL,trace elements and adhesion molecule in two groups were compared,and all the indexes of observation group with different types and severity were compared too.Results The level of IL-4,IL-5,IL-6,IL-10,soluble intercellular adhesion molecule (sICAM)-1,soluble vascular cell adhesion molecule (sVCAM)-1,soluble P-selectin (sP-selectin),soluble E-selectin (sE-selectin) in observation group were significantly higher than those in control group [(28.97 ± 3.27) ng/L vs.(4.35 ± 0.65) ng/L,(17.46 ± 2.15) ng/L vs.(2.71 ± 0.34)ng/L,(10.39 ± 1.28) ng/L vs.(5.96 ± 0.94) ng/L,(31.36 ± 3.44) ng/L vs.(5.53 ± 0.76) ng/L,(483.72 ± 39.25) μ g/L vs.(319.65 ± 29.86) μ g/L,(516.85 ± 50.27) μ g/L vs.(327.46 ± 31.53)μg/L,(12.58 ± 1.36) μg/Lvs.(3.43±0.76) μg/L,(31.34 ±2.84) μg/L vs.(10.22± 1.52)lμg/L] (P＜0.05).The level of serum Zn in observation group was significantly lower than that in control group[(7.14 ±1.35) μ mol/L vs.(16.83 ± 1.71) μ mol/L] (P ＜ 0.05).The level of serum Cu and Mn in observation group were significantly higher than those in control group [(23.24 ± 2.79) μ mol/L vs.(13.15 ± 2.08) μ mol/L,(4.13 ± 0.27) μ mol/L vs.(2.24 ± 0.19) μ mol/L] (P ＜ 0.05).In observation group,the change of above indexes in continuity and severe patients had significant difference compared with intermittence and mild,moderate patients (P ＜ 0.05).Conclusions The change of IL,trace elements and adhesion molecule in allergic rhinitis patients are obviously,and among different types and degrees,the change are obviously too.So,these indexes can be the important basis of clinical diagnosis and treatment.

The key policy for the Chinese governments to support the health insurance development has been to provide high percentage of premium subsidies in the 1 . 1 billion Yuan insured for the two of the basic medical insur-ance systems. According to the current policy, governments should share the responsibility of several hundreds of bil-lions Yuan of subsidies per year. However, because of the indistinct of the responsibility between governments at all levels and the shortage of systematic and long-term duty share mechanism, the current system has been directly affect-ing the fairer and more sustainable health insurance system development. Concerning these issues, this paper primari-ly thought about the contributory principle of subsides after analyzing the present situation and the main problems. Therefore, taking the three factors including disposable income per capita, consumption expenditure per capita and fi-nancial revenue per capita into account, it provides a“5 steps approach” about the contribution of the central govern-ment fiscal subsides using entropy evaluation method, and suggests a proposed program on the governments contribu-tion liability at the provincial or decentralized level based on the “fiscal subsides index”. Thoughts and conclusions drawn from this paper have a significant meaning into the establishment of a fairer and more sustainable financial sup-port mechanism for the basic medical insurance.

The standardized resident training is an important and necessary way to cultivate high-quality medical talents.The goals between clinical and imaging residents in standardized training of ultrasound department are different.For clinical residents,the purpose is to understand the ultrasound images of various common diseases,combine clinical manifestation with ultrasound images,and improve the level of clinical diagnosis and treatment.For imaging residents,the goal is much higher and stricter;they need to master solid ultrasonic knowledge,independent operational and diagnostic ability,in order to provide reliable and accurate ultrasonic diagnosis.We individually design the teaching plan and methods in ultrasound department,in order to improve teaching efficiency and quality.

Aim To study the effects of pyrrolidine dithiocarbamate(PDTC) on matrix metalloproteinase-9(MMP-9) expression in alveolar macrophages(AM) induced by TNF-?,and then to explore it's signal pathway.Methods AM were collected from bronchoalveolar lavage fluid in patients with chronic obstructive pulmonary disease.AM were pretreated with PDTC and then stimulated by TNF-? or IL-1.MMP-9 mRNA expression was detected by semi-quantitative reverse transcription-polymerase chain reaction and MMP-9 protein expression was detected by Western blot.Phospho-I?B? protein levels induced by TNF-? or IL-1 were detected by Western blot.NF-?B activity was detected by electrophoretic mobility shift assay.Results Both the mRNA and protein levels of MMP-9 induced by TNF-? in AM were significantly elevated in a dose dependent manner(P0.05).PDTC had distinct effect of inhibiting the activation of NF-?B induced by TNF-? or IL-1 in a dose-dependent manner(P0.05).Conclusions NF-?B plays an important role in MMP-9 expression induced by TNF-? in AM;PDTC can down-regulate MMP-9 expression induced by TNF? in AM possibly through preventing the degradation of I?B? via ubiquitylation-proteasome proteolytic pathway.
