The major pathogenic bacterium of catheter-related bloodstream infection is gram-positive bacteria.The occurrence of catheter-related bloodstream infection is related with exogenous factors and endogenous factors.It is suggested that catheter-related bloodstream infection should be diagnosed without removing the catheter.It is shown that the catheter should be removed and the patient should use antibiotics as soon as possible if catheter-related bloodstream infection occurred.Buliding a detection system,using antimicrobial dressings and antimicrobial central catheters,and improving patient's nutritional status can decrease the morbidity of catheter-related bloodstream infection.The authors summarize the epidemiology,diagnosis,treatment and prevention strategies of catheter-related bloodstream infection.

Objective To investigate the psychological state of high-risk pregnancy mothers af-ter being separated from their newborns and discuss the influencing factors of psychological state. Methods Nonexperimental descriptive study was used in this study. The investigation adopted state-trait anxiety inventory (STA-Ⅰ) and Edinburgh postnatal depression scale (EPDS). Results The moth-ers' anxiety score was significantly higher than normal women in China, and postnatal depression inci- dence rate was 57.9%. Mothers' psychological state was correlated with gestational age of new-borns, trait anxiety and pregnancy complications. Conclusions The psychological state of high- risk pregnancy mothers after being separated from their newborns should be paid more attention to, and cor-related nursing methods should be taken to improve their mental health.

OBJECTIVE To investigate the relationship between state trait anxiety and behavioral status in patients with sudden deafness. METHODS From April 2015 to June 2016, 140 cases of hospitalized patients with sudden hearing loss were selected as the observation group, and 140 healthy volunteers in our hospital for medical examination were selected as the control group. Average data, state trait anxiety, quality of life, and behavior survey were investigated in the two groups and correlation analysis was conducted. RESULTS The state trait anxiety score of the observation group was 51.20±4.19 points, and the control group was 34.40±3.49 points, and the state trait anxiety score of the observation group was significantly higher than that of the control group(t=12.949, P<0.05). The scores of physical, compulsive, interpersonal sensitivity, hostility and depression in the observation group were significantly higher than those in the control group(P<0.05). The problem solving and help scores in the observation group were significantly lower than that of the control group, while the fantasy and self accusation scores was significantly higher than that of the control group(P<0.05). In the observation group, Pearson correlation analysis shows anxiety scores were significantly correlated to the dimensions scores of quality of life, fantasy and self accusation scores(P<0.05), and were significantly negative correlated to the problem solving and help scores (P<0.05). CONCLUSION The patients with sudden deafness is accompanied by state trait anxiety and fantasy, self accusation and other bad behavior, it can seriously affect the patient's quality of life and form vicious circle, so the nursing intervention should be strengthened in clinical practice.

Objective To study the diagnosis and treatment of syncope by analyzing its etiology.Methods Ninety-six syncope patients admitted to our hospital from 2014-01-01 to 2016-12-21were included in this study.The etiology of syncope was analyzed.Results Of the 96 syncope patients included in this study,50 (52.1 ％) were diagnosed with nerve-mediated reflex syncope,31(32.3％) with orthostatic hypotensive syncope,10 (10.4％) with cardiogenic syncope due to arrhythmia,coronary atherosclerotic cardiopathy or pulmonary embolism,5 (5.2％) with other diseases.Conclusion Nerve-mediated reflex,orthostatic hypotension and cardiogenic factors are the causes of syncope.Attention should thus be paid to syncope caused by nervous system diseases.Clarification of the risk factors for syncope helps to reduce its potential risk.

Objective To investigate the method to prevent the displacement of tissue expander implanted between the panniculus carnosus and deep fasia in rabbits .Method 40 rabbits were divided into two groups randomly: the experimental group and the control group .Through an incision on the back , a pocket was made by dissecting between the rabbit panniculus carnosus and deep fasia .The panniculus carnosus at the pocket boundary were sutured with the deep fascia inside the pocket by interrupted 3-0 sutures.A 50 mL kidney-shaped tissue expander was implanted .The expander was inflated with 10 mL saline after the wound was sutured .7 days after implantation , black tattoos were made on the skin around the expander to mark the site of expander .Two months after implantation , the expanders in the experimental group were inflated with 10 mL saline weekly to a total of 140 mL.7 days after implantation the expanders of control group were inflated with 10 mL saline weekly to a total of 140 mL.The incidence of expander displacement , dehiscence of incision , reversal of injection pot and death were recorded .Results There was no expander displacement in the 19 rabbits of experimental group .All the expanders were located within the tattoo area .There was no expander displacement in 11 rabbits of the control group .4 expanders of the control group moved from the back to belly .The difference between them was statistically significant ( P <0.05 ) .The incidence of dehiscence of incision in the experimental group was not significantly lower than that in the control group ( P >0.05 ) .Meanwhile there was no significant difference in the incidences of reversal of injection pot , infections and deaths ( P >0.05 for all ) .Conclusions Sutures between the panniculus carnosus and the deep fascia at the pocket boundary asisted by delayed inflating can prevent the displacement of tissue expander implanted between the panniculus carnosus and deep fasia in rabbits , thus to obtain effective expansion .

Hepatitis B virus (HBV)-related liver failure is an end-stage liver disease with a high mortality.Biomarkers,which are of interest,are helpful for diagnosis and treatment of liver failure.The purpose of this review is to highlight the recent advances in this field.Although many new biomarkers can improve the prognostic efficacy,the dynamic biochemical function of liver and kidney as well as the function of coagulation are still the most practical and common indexes for the development and prognosis evaluation of liver failure.

Objective To investigate the impact of using antithrombotic drugs (anticoagulants or antiplatelet aggregation drugs)before the onset of cerebral infarction on hemorrhagic transformation after acute cerebral infarction. Methods The consecutive patients with acute cerebral infarction from Chengdu Stroke Registry Project admitted to the Department of Neurology,West China Hospital,Sichuan University from January 1,2004 to January 1,2014 were enrolled. The baseline data on admission,previous usage of anticoagulants and anti-platelet aggregation drugs,as well as CT/ MRI and other imaging data of all patients were collected. According to the results of CT/ MRI reexamined at 72 h after admission,the patients with hemorrhagic transformation were enrolled into a hemorrhagic transformation group;the patients with non-hemorrhagic transformation were enrolled into a non-hemorrhagic transformation group according to the ratio
of 1 ∶ 1. Their gender and age were matched with the hemorrhagic transformation group. The baseline data and drug used of the patients in both groups were compared. The differences of risk factors between the two groups were analyzed with multivariate Logistic regression analysis. The relationship between hemorrhagic transformation and premorbid use of antithrombotic drugs were observed. Results A total of 6 916 patients with acute cerebral infarction were enrolled,including 433 (6. 3%)hemorrhagic transformation (hemorrhagic transformation group)and 433 non-hemorrhagic transformation. (1)There were significant differences between the patients of the two groups on admission in the National Institutes of Health Stroke Scale (NIHSS)score,atrial fibrillation,previous cerebral infarction,and blood glucose levels on admission (all P < 0. 05). (2)The proportions of using anticoagulants and antiplatelet aggregation agents in the hemorrhagic transformation group were higher than those of the non-hemorrhagic transformation group (anticoagulants:14. 1% [n = 61]vs. 3. 9% [n = 17];P < 0. 01,OR,4. 01,95% CI 2. 303 -6. 993;anti-platelet aggregation drugs:14. 3% [n =62]vs. 8. 3% [n = 36];P = 0. 005,OR,1. 84,95% CI 1. 194 -2. 846). (3)The results of multivariate Logistic regression analysis showed that the use of anticoagu-lants,anti-platelet aggregation drugs,NIHSS score on admission,and random blood glucose on admission were the independent risk factors for hemorrhagic transformation (OR [95% CI]3. 302 [1. 860 -5. 862], 2. 081 [1. 281 -3. 382],1. 047 [1. 026 -1. 069],and 1. 055 [1. 011 -1. 100],respectively (all P <0. 05). Conclusion The NIHSS score and blood glucose levels on admission are the independent risk factors of hemorrhagic transformation. Using anticoagulants or anti-platelet aggregation drugs before symptom onset is independently associated with hemorrhagic transformation,however,its relationship with the long-term prognosis of acute cerebral infarction need to be further studied.

So far, the major therapeutic drugs of diabetes are western medicine , but side effects of hypoglycemic western med-icine are large and not easy to take for a long time .In recent years , we found the side effects of some kind of hypoglycemic Chinese herbal medicine were small , much easier to be accepted by the patients .Thus, the clinical treatment of diabetes may have new meth-ods.According to the mechanisms of Traditional Chinese Medicine for protection of islet function , this review will discuss them from re-ducing oxidative stress , increasing the number of islet cells and promoting βcells to secrete, relieving insulin resistance , increasing in-sulin sensitivity and so on .All of these aspects reflect the unique role of Traditional Chinese Medicine in the treatment of diabetes and protection of islet function .
