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 provide some suggestions for improving the pharmaceutical advertisement supervision system and standardizing the pharmaceutical advertisement market. Methods: Literature reviews, statistical analysis and interviews were adopted to study the status quo and difficulties of pharmaceutical advertisement supervision and pharmaceutical advertisement trends. Results:The top-level design of pharmaceutical advertisements supervision sys-tem has two defects:the separation between approval and penalty and the obstacles to cooperation at all levels of the drug administration. The worsening status quo of illegal drug advertising has elicited concern from scholars and regu-lators. However, there are still some difficulties in the supervision of drug advertisers, advertising agents, and pub-lishers. Conclusion:It is suggested that the drug advertising regulation system should be perfected by strengthening information supervision, establishing a coordination mechanism and consolidating self-discipline consciousness. Addi-tionally, laws and regulations should be promptly revised as an essential way to improve the effects of supervision.

Purpose To investigate the comparison of miR-106a in fresh and paraffin-embedded tissues and its expression in precan-cerous 1esions of gastric cancer. Methods Human gastric cancer tissues inc1uding 30 coup1es of fresh and 40 coup1es of paraffin-em-bedded samp1es were co11ected,quantitative rea1-time PCR was used to detect the expression of miR-106a in these two samp1es. Anoth-er paraffin-embedded samp1es inc1uding 20 cases of precancerous 1esions and 40 cases of gastric adenocarcinoma were a1so co11ected,in situ hybridization was used to assess the expression of miR-106a in these stages. Results The re1ative expression of miR-106a in fresh tissues was 3. 25 ± 1. 99,in paraffin-embedded tissues was 3. 18 ± 2. 14,indicating that the expression of miR-106a in these two sam-p1es has no statistica1 difference(P>0. 05),corre1ation ana1ysis showed that there was a significant corre1ation of miR-106a expression in these two samp1es(rs =0. 998,P<0. 001). The expression of miR-106a was detected in the stage of precancerous 1esions with the positive rate was 70%. The positive signa1s were 1ocated in dysp1astic epithe1ia1 ce11s and appeared as dark b1ue fine granu1es. The positive rate of miR-106a in gastric cancer tissues was 87. 5% and the frequency and extent increased and enhanced compared with pre-cancerous 1esions. Conclusion miR-106a has significant corre1ation in gastric cancer fresh tissues and paraffin-embedded tissues. Detection of miR-106a with paraffin tissues and its ear1y changes in prema1ignant 1esions can provide va1uab1e information for the ear1y diagnosis of gastric cancer.
