The authoritative coefficients were 0.83 and 0.84, the coordination coefficients were 0.586 and 0.601, respectively. The index system consisted of 2 first-level indexes and 21 second-level indexes. Conclusions A reliable and scientific risk factors evaluation index system for peri-operative hypothermia was developed. It can be utilized to provide theoretical foundation for the prevention of peri-operative hypothermia.

The prevalence of childhood primary hypertension is increasing each year,not only bring-ing symptoms to these children,but also causing damage to multiple target organs such as heart,kidney,blood vessels,eyes and nerve system. Childhood hypertension is a risk factor of adult hypertension. Paying atten-tion to and preventing childhood hypertension has become a public health challenge. There are many associat-ed risk factors for childhood primary hypertension,including parental hypertension,overweight and obesity, low birth weight,and so forth. From the analysis of these factors,suggestions can be given about how to pre-vent childhood primary hypertension.

Objective To observe the changes of serum soluble form of triggering receptors expressed on myeloid cell-1 (sTREM-1) level in full-term newborns with infection and to investigate the relationship between serum sTREM-1 and neonatal bacterial infection.Methods Eighty-five full-term newborns admitted to the neonatal ward of Shanghai Children s Hospital of Shanghai Jiaotong University were selected into this study.According to the locations and severity of infection,patients were divided into 3 groups: severe infection group (n = 27),mild infection group (n = 28),non-infection group (n = 30).The samples of infection groups were collected before using antibiotics and within 48 h after infection symptom occurred; others were collected during hospitalization.For the neonates with organ dysfunction in the severe infection group,samples were also collected at the third and seventh day of infection.Serum sTREM-1 was measured by enzyme-linked immunosorbent assay.Analysis of variance was used to compare the difference between groups.Receiver operating characteristic (ROC) curve was used to calculate the sensitivity,specificity,positive and negative predictive value and Youden index.Results (1) Serum sTREM-1 level of severe infection group[(91.2±47.3) pg/ml] was significantly higher than that of mild infection group[(68.8 + 30.4) pg/ml] and non-infection group[(35.5±17.6) pg/ml],respectively (P＜0.05).(2) Serum sTREM-1 level of the survival newborns (n= 17) in the severe infection group was lower than that of dead ones[(73.1±34.9) pg/ml vs (121.6±49.3) pg/ml,t= - 2.995,P = 0.006].(3) For the survival patients,the serum sTREM-1 level decreased in the first week of infection,while that of dead patients increased,the cut-off value was 100.6 pg/ml.(4) Based on the ROC analysis,43.8 pg/ml was selected as the the cut-off value,area under the curve was 0.868,and sensitivity was 85.5%,specificity 80.0%,positive predictive value 0.887,negative predictive value 0.750,Youden index 0.655.Conclusions Serum sTREM-1 level increases in neonatal infection.The change of serum sTREM-1 level in patients with severe infection is correlated to the prognosis.

Aim To observe the effects of amlodipine on cell cycle,cell cycle-related genes and cyclin expression of human breast carcinoma MCF-7 cells.And to probe effects of amlodipine on cell cycle and its mechanism of human breast carcinoma MCF-7 cells.Methods In vitro growth inhibitory effects of amlodip-ine on human breast carcinoma MCF-7 cells were determined by MTT assay,cell cycle distribution was detected by flow cytometry,the Mrna expression levels of cell cycle-related genes cyclinD1 and p21 were treated by RT-PCR,and the protein expression of cell cycle protein cyclinD1 and p21 were assessed by Western blot.Results With dose and time dependently,amlodipine could inhibit the proliferation of human breast carcinoma MCF-7 cells in vitro.The IC_(50) was 14.439 μmol·L~(-1).When breast cancer cells MCF-7 were treated with 7.22 μmol·L~(-1)(1/2 IC_(50)),14.439 μmol·L~(-1)(IC_(50))and 28.88 μmol·L~(-1)(2IC_(50))amlodipine for 48 h,the ratios in the G_0/G_1 phase were significantly increased as compared with control group(P<0.05).Amlodipine inhibited the expression of Mrna and protein of cyclinD1,while increased the expression of Mrna and protein of p21.Conclusions Amlodipine exhibits obvious anti-tumor activities on human breast carcinoma MCF-7 cells and arrest cell cycle in G_1 phase.The mechanism of G_1 phase arresting may be related to modulating the Mrna and protein expression of cell cycle-related gene cyclinD1 and p21.

Objective To observe the clinical efficacy of grain-sized moxibustion in treating cancer-related fatigue and improving the quality of life of patients with malignant tumor. Method Forty-six patients with malignant tumor were randomized into a grain-sized moxibustion group and a control group. The grain-sized moxibustion group received grain-sized moxibustion plus regular treatment, while the control group received the regular treatment only. The cancer-related fatigue intensity [Karnofsky Performance Status (KPS), European Organization for Research on Treatment of Cancer Core Quality-of-life Questionnaire (EORTC QLQ-C30), Piper Fatigue Scale (PFS)], white blood cell count, hemoglobin level, lymphocyte count, and neutrophil count were compared before and after treatment between the two groups. The correlation between cancer-related fatigue and the observed indexes was also analyzed. Result The grain-sized moxibustion group was better than the control group in mitigating the cancer-related fatigue, up-regulating hemoglobin level, and improving the symptoms (P<0.05). Conclusion Grain-sized moxibustion can effectively mitigate cancer-related fatigue via improving anemia condition and the symptoms of malignant tumor patients, and it can also enhance the quality of life of the patients.
