Most of clinicians'researches are investigator-initiated clinical trial.There is a great difficulty in not knowing what to choose.Clinicians can think about the etiology and incidence, treatment effect evaluation, diagnostic methods and prognosis prediction.Clinicians can also find topics from clinical practice, from clinical guidelines, from literature and from different perspectives.If there is no high quality level of research evidence, it can be used as a research topic.

Objective In order to reduce patients’ radiation doses and decrease the exposure time of the CT Tube. By summarizing experiential methods from the previous practice work, we hope to draw an optimized scheme of CT scanner. Methods We analyzed the continuous clinical examples in four months, changed the different levels of parameters slowly, optimized acquisition conditions and retrospected the CT radiative dose. In the meantime, we counted the monthly CT Bulb exposure time, exposure time per capita tube data and so on. Results Compared with former result, the average CT radiative dose per person is decreased 84.72%, which conventional bone, the smal joints of the bone, the brain and the heart radiation reduced respectively 83.82%, 88.80%, 86.78% and 84.49%, and the differences are statistical y significant. The exposure time of optimized CT Tube is 2 031 s. Conclusions Using the CT scan optimization scheming has great efforts in the practice of clinical nuclear medicine, can reduce the exposure time of the CT Tube and improve the lifetime of the bulb. Therefore, it can be widely used.

Many advances have been achieved in the clinical and basic studies on metastasis and recurrence of hepatocellular carcinoma (HCC) over the past 20 years.The achievements mainly include the following aspects:(1) a group of molecules related to metastasis and recurrence including osteopontin have been identified,and multi-molecular predictive models for metastasis have been established and optimized;(2) it has been found that the imbalance of immune response in tumor microenvironment is important in promoting metastasis and can be used to predict metastasis and recurrence;(3) it has been found and confirmed that interferon can prevent postoperative recurrence,and patients with a lower miR-26a expression level can achieve greater benefits;(4) the breakthroughs in liquid biopsy and immunotherapy bring a promising future for the prediction,prevention,and treatment of HCC metastasis and recurrence.However,these predictive models still need to be validated by multi-center studies,and the effects of adjuvant transarterial chemoembolization and targeted therapy with sorafenib still need further evaluation.

Objective To evaluate the effect of propofol combined with dezocine on postoperative recovery period agitation and postoperative pain in patients with operation under general anesthesia.Methods A total of 52 patients with operation under general anesthesia were randomly divided into control group and treatment group,26 cases in each group.At 15 min before the end of operation,control group was given dezocine 0.15 mg · kg-1 + fentanyl 0.6 μg · kg-1,intravenous injection.Treatment group was treated with dezocine 0.15 mg · kg-1 + propofol 2.0 mg · kg-1,intravenous injection.Postoperative eye opening time,extubation time,extubation of mean arterial pressure (MAP),heart rate (HR),sedation,pain score and safety were compared between the two groups.Results After surgery,eye opening times in control group and treatment group were (13.28 ± 0.63),(9.21 ± 0.37) min.Extubation times in control group and treatment group were (17.23 ± 1.14),(13.74 ± 1.02) min.The MAP in control group and treatment group were (97.64 ±9.34),(90.13 ± 7.32)mmHg.The HR in control group and treatment group were (86.34 ± 5.27),(78.46 ± 6.47) time · min-1,with significant difference (all P ＜ 0.05).The sedation-agitation scales (SAS) in control group and treatment group were 5.03 ± 0.45,3.49 ± 0.17.The visual analogue scales (VAS) in control group and treatment group were 4.23 ± 0.24,2.11 ± 0.16,with significant difference (all P ＜ 0.05).In control group,adverse drug reactions were dizziness,nausea and vomiting,the incidence of adverse drug reactions was 11.54％ (3/26 cases).The adverse drug reactions in treatment group were nausea,vomiting,hypotension and adverse drug reactions was 7.69％ (2/26 cases),with no significant difference (P ＞ 0.05).Conclusion Compared with fentanyl and dezocine,the propofol and dezocine can significantly reduce the degree of postoperative recovery period agitation and pain after operation in patients with operation under general anesthesia,stable extubation MAP and HR,and do not prolong the time of awakening and extubation,and the safety was high.

Objective To explore the status of resource utilization and oral health of elderly with diabetes mellitus, and to analyze the correlation between the two.Methods Totals of 659 elderly with diabetes mellitus were surveyed by the chronic illness resources survey (CIRS) and the geriatric oral health assessment index (GOHAI).Results Total scores of resource utilization of the elderly with diabetes mellitus were (71.69±15.86) points, and quality evaluation scores of oral health were (47.12±9.05). Dimensions in resource utilization were positively correlated with dimensions in oral health (P<0.05).Conclusions For the elderly patients with diabetes mellitus, the higher the resource utilization is, the better oral health is.

Objective To investigate the value of adenosine triphosphate(ATP)bioluminescence assay for assessing object surface contamination degree in intensive care unit(ICU).Methods 30 groups of high frequency contact object(including ventilator panel,bedside table and computer keyboard)in ICU from January to December 2016 were enrolled for the study. Each object was sampled and evaluated before and after disinfection,and their surface was divided into two areas,whose sur-face contamination degree was evaluated by ATP bioluminescence assay and bacterial culture method that were classified as ATP group and control group.The fluorescence detection value and colony number were compared between two groups be-fore and after disinfection.The correlation between the fluorescence detection value and colony number was analyzed by Pearson correlation in the same sample,and the Kappa consistency test was used for the qualification rates of two detections. Results ①The fluorescence detection value and colony number of ventilator panel,bedside table and computer keyboard af-ter disinfection in two groups were significantly lower than that before disinfection(t=8.107~26.393,all P<0.05).②Pearson analysis result showed that both before and after disinfection,the fluorescence detection value had no significant cor-relation with colony number of ventilator panel,bedside table and computer keyboard(r=0.199~0.338,all P>0.05).③There were no significant differences in the qualification rate between two groups of ventilator panel,bedside table and com-puter keyboard before and after disinfection(χ2=0.000~1.404,all P>0.05).The qualification rate before the disinfection of ATP group and control group were 0 and 8.9%,and that after disinfection were 86.7% and 91.1%,whose Kappa consis-tency test result showed that the Kappa value was 0.776(95%CI:0.575~0.978)>0.75,so the consistency was quite sat-isfied.Conclusion ATP bioluminescence assay could be used as a rapid and handy preliminary screening to assist bacterial culture method to evaluate the object surface contamination in ICU,and the result was satisfactory and it would be worthy of clinical application.
