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 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.

Objective: To investigate the relationship between serum albumin level and severity of coronary heart disease (CHD). Methods: A total of 237 patients admitted in our hospital from 2008 to 2009 and undergoing coronary angiography were enrolled. CHD severity was evaluated according to clinical types, number of diseased coronary vessels and coronary artery score respectively, and patients were divided into non-CHD group (n=84), angina pectoris group (n=92) and myocardial infarction group (n=61). Serum total protein, albumin and globulin were measured in all patients on second day after admission. Relationship among indexes of CHD severity and serum proteins were analyzed. Results: Compared with non-CHD group, there was significant decrease in albumin level [(40.22±3.56) g/L vs. (39.81±3.56) g/L vs. (38.68±3.43) g/L, P<0.05] in angina pectoris group and myocardial infarction group. Spearman correlation analysis indicated that serum albumin level was significant negatively correlated with clinical types (r=-0.18, P=0.005), number of diseased coronary vessels (r=-0.195, P=0.003) and coronary artery score (r=-0.188, P=0.004). Serum total protein, globulin and ratio of albumin/globulin were not significantly correlated with clinical types, number of diseased coronary vessels and coronary artery score (P>0.05). Conclusion: Serum albumin level is negatively correlated with severity of coronary heart disease. Low serum albumin may be a risk factor for coronary heart disease.

The optimal treatment of elderly women with breast cancer still faces many difficulties. Life expectancy, comorbidity, and functional status influence clinical decision and survival. Standard adjuvant medical treatments should not be withheld from healthy older patients with reasonable life expectancies. In this study, adjuvant medical treatment literatures for elderly breast cancer patients, including endocrine therapy, chemotherapy, and HER2-targeted therapy, were reviewed, focusing on efficacy and toxicity of drugs for elderly women.

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.

Objective To compare the effect of different methods of anesthesia on cerebral autoregulation in patients undergoing neurosurgery.Methods Sixty-nine ASA Ⅱ orⅢ patients with brain tumor, aged 23-62 yr, scheduled for neurosurgery under general anesthesia, were randomly divided into 3 groups ( n = 23 each) : propofol-remifentanil group (group PR), sevoflurane-remifentanil group (group SR) and propofol-sevoflurane-remifentanil group (group PSR) . Anesthesia was induced with target-controlled infusion (TCI) of propofol (target plasma concentration3 μg/ml, PR and PSR groups) or inhalation of 8% sevoflurane (group SR) and iv injection of remifentanil 1 mg/kg and atracurium 0.5 mg/kg. The patients were mechanically ventilated after tracheal intubation. PETCO2 was maintained at 32-35 mm Hg. Anesthesia was maintained with TCI of propofol (target plasma concentration 2.0-3.5 μg/ml) in group PR, with inhalation of 1.5%-2.5% sevoflurane in group SR, with TCI of propofol (target plasma concentration 1.5-3.0 μg/ml) and inhalation of 1% sevoflurane in group PSR, and with TCI of remifentanil (target plasma concentration 2.0-4.5 ng/ml) and iv infusion of atracurium at 6 μg · kg-1 · min-1 in all groups. Auditory evoked potential index was maintained between 40-45. The middle cerebral artery time-average peak flow velocity was recorded before induction (baseline) , immediately after intubation, immediately before craniotomy and at the beginning of skin suture. The unilateral carotid artery was compressed for 7 s at the corresponding time points mentioned above. The transient hyperemic response ratio (THRR) was calculated to reflect cerebral autoregulation. Results Compared with the baseline value at T0, THRR was significantly increased at T2in group PR and decreased at T2,3 in group SR (P <0.05) ,while no significant change was found in THRR at T1-3in group PSR (P >0.05). The THRR was significantly lower in SR and PSR groups than in group PR, and higher in group PSR than in group SR ( P < 0.05). Conclusion Propofol-remifentanil anesthesia can improve cerebral autoregulation, sevoflurane-remifentanil anesthesia can reduce cerebral autoregulation, and propofol-sevofluraneremifentanil anesthesia exerts no effect on cerebral autoregulation in patients undergoing neurosurgery.
