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.

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.

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.

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 observe the efficacy and safety of atorvastatin calcium combined with metoprolol in the treatment of chronic congestive heart failure (CHF). METHODS:207 CHF patients were randomly divided into control group (102 cases) and observation group (105 cases). Control group received cardiac,diuretic,vasodilating and oxygen inhalation,Metoprolol tar-trate tablet with initial dose of 6.25 mg,2-3 times a day,then increased 6.25-12.5 mg based on the improvement,2-3 times a day. Observation group additionally received 80 mg Atorvastatin tablet,twice a day. The treatment course for both groups was 16 w. Clinical efficacy,cardiac functions [left ventricular ejection fraction(LVEF),left ventricular end systolic diameter(LVESD),mi-tral early diastolic and late diastolic peak flow velocity ratio(E/A)],blood lipids [lipoprotein(a)Lp(a),triglyceride(TG),total cholesterol(TC)] levels before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant (P<0.05). Before treatment,there were no significant differences in cardiac functions and blood lipids in 2 groups(P>0.05). Af-ter treatment,the LVEF and E/A in 2 groups were significantly higher than before,and observation group was higher than control group,LVESD,Lp(a),TG and TC were significantly lower than before,and observation group was lower than control group,the differences were statistically significant (P<0.05). And there was no significant difference in the incidence of adverse reactions (P>0.05). CONCLUSIONS:Based on conventional treatment,the efficacy of atorvastatin calcium combined with metoprolol is su-perior to metoprolol in the treatment of CHF,with better safety.

Objective: To evaluate the clinical effect of the double-orifice technique in the treatment of the anterior leaflet prolapse of mitral valve.
