Objective: To study the relationship between negative behavior of preschool children and behavior of their mothers. Method.. 742 mothers of children in their 3 ～ 6 year old age were tested by self- made questionnaire. Results: Negative behavior was not significantly related to age and gender of children. It was negatively related to maternal supporting behavior and positively to maternal un- supporting behavior. The culture background (urban/rural), family income and mother' s occupation were found to be important factors mediating maternal un- supporting behavior. Conclusion: Negative behavior of preschool children is influenced by mother' s behavior, which in turn has its cultural - economical background.

Objective:To investigate the routine maintenance and inspection methods of magnetic resonance imaging (MRI) equipment, reduce the failure rate and improve the image quality, and ensure the normal operation of medical image diagnostic equipment.Methods:According to the characteristics of the equipment, to make maintenance inspection goals and complete the daily management of MRI equipment. According to the medical equipment management system requirements, to establish and maintain records to provide data to meet the requirements and the effective operation of quality management system, and to record the data for each equipment for continuity and traceability.Results: There are the potential problems through the management and analysis of MRI equipment data. And the problems were timely solved to make the device operate steady. It’s easy to get a clear and reliable image and to provide an objective and true diagnostic basis for clinical.Conclusion: The routine maintenance and inspection of MRI equipment is an indispensable and important work in medical engineering.

Objective To understand the current situation of multidrug-resistant organism (MDRO)infection in hospitalized patients in a tertiary first-class hospital,as well as efficacy of bundle intervention measures on preven-tion and control of infection. Methods Hospitalized patients who were infected with MDROs in this hospital during 2012-2014 were monitored and conducted bundle intervention. Results In 2012-2014,a total of 1909 MDRO strains were isolated. The isolation rates of MDROs in 2012-2014 were 30.69% ,31 .04% ,and 29.40% respec-tively,bedside intervention rates were 81 .02% ,92.05% ,and 94.23% respectively,implementation rates of clinical isolation were 69.97% ,82.98% ,and 93.04% respectively;MDRO isolation rates during 2012-2014 were not sig-nificantly different(P>0.05);bedside intervention rates and implementation rates of clinical isolation were both sig-nificantly different(both P<0.05). The top 3 isolated MDROs in 2012-2014 were extended-spectrumβ-lactamases (ESBLs)-producing Escherichia coli,multidrug-resistant Acinetobacter baumannii,and ESBLs-producing Klebsiel-lapneumoniae. Conclusion Bundle intervention measures,such as multi-department collaboration and strengthened on-site supervision,can promote more standardized management of healthcare-associated infection,enhance the im-plementation rate of clinical isolation,and effectively prevent and control the spread of MDRO in hospital.

The Medical Care Act of Japan has undergone five major revisions since it went into effect in 1947. Each revision has been designed to target and tackle main problems found in the medical and health sector in the country. These problems range from the making of regional healthcare plans to the establishment of the hospital with specific functions, from the division of rehabilitation beds to the establishment of nursing insurance scheme, from the birth of medical corporations to the establishment of social medical corporations, and from strengthening of non-profit nature of medical institutions to the construction of medical information system. These efforts were made to provide a safe and convenient health service for the Japanese people. These revisions are closely related to hospital management, and its experiences prove useful for the health reform in China.

The clinician training system in Japan is different from that in China as their medical students are allowed to take medical doctor examination immediately following their graduation.But they must undergo at least two years of training in basic clinical knowledge and skills prior to taking any clinical practice.This training system is inspirational for us as follows:China should include standardized training of residents into the law of medical practitioners,and medical graduates must take two years of knowledge training in full medicine before they are qualified for clinical practice.On top of this training,they need to undergo at least three years of specialized doctor training,making them competent clinicians with comprehensive knowledge coverage and outstanding skills in specific areas following such staged training.

For medical insurance systems, medical expense examination is a key measure to keep medical expenses under control. In 1948, Japan established an examination authority of legal person status to operate the medical expense examination. Based on years of modifications and improvement in the organizational system and operation mechanism, the system is running smoothly by now. Authors of this paper made a detailed introduction to the specific operations of such a system, and to China's local features as well. On such basis, the study proposed to build in China a third-party medical expense examination institution as a legal entity, and practice the reexamination system and information disclosure system, in an effort to safeguard legitimate rights of insurance organizations and medical institutions.

Hepatic fibrosis is a wound-healing re-sponse to all kinds of chronic liver injury, which if persistent can lead to cirrhosis. Once develops to cirrhosis, the only ef-fective therapy will be liver transplantation. In recent years,many scholars have taken all kinds of methods to try to pre-vent liver fibrosis developing to cirrhosis. As auto adult stem cell possesses multi-directional differentiation and none reject reaction advantages, it has become the study hotspot of nu-merous researches for hepatic fibrosis therapy and acquired significant progression.

Objective To analyze the recent condition on medication safety of the elderly with chronic diseases in poor areas of Liaoning Province, the structural equation model(SEM) was used to investigate the influencing factors of the medication safety in order to provide the scientific basis for medication safety and the rational use of drugs. Methods The 1 690 elderly with chronic diseases in poor areas of Liaoning Province were selected by the multi-stage random sampling and investigated with the self-designed questionnaire, the database was established on SPSS17.0, the model of structural equation modeling was built by AMOS17.0. Results The four common factors, which were the knowledge,attitude, practice and adherence of medication safety, were extracted by confirmation factor analysis, and the data of the four common factors was fitted, the fitting parameters were: χ2/DF=2.254, GFI=0.913, NFI=0.909, CFI=0.925, AGFI=0.825, RMSEA=0.062, the model fitting was ideal. Conclusions The medication of the elderly with chronic diseases in poor areas of Liaoning Province exists potential security risks, the knowledge, attitude, practice and adherence of medication safety are the important factors which affect the medication safety, the health education about medication safety should be conducted in the elderly with chronic diseases in the poor areas, to develop the safety, effectiveness and economy of medication among the elderly.

The number of people needed to accept radiotherapy is increasing with the higher incidence of tumor,and the continuous development of radiation therapy technology has extended the longterm survival of patients.Avoiding the occurrence of radiation damage is particularly important.Since NF-κB plays an important role in gene transcription and regulation of radiation damage,this article introduced the structure,activation and function of NF-κB,reviewed the findings of NF-κB alterations in radiation injuries of brain and lung,and sketched the studies of NF-κB inhibitor.
