Hedging is an important component of vague language. This paper retrieves high frequency expressions of hedgingby using medical English corpus. Pragmatic functions of hedging are analyzed, which can be summarized as politeness principle, authors' self-protection, avoidance of the absolute, pursuit of objectiveness as well as conversational implication. To medical researchers, it is necessary to cultivate the awareness of hedging and learn how to adopt it in their research papers.

ObjectiveTo investigate the risk factors,prevention measures and treatment methods of the pulmonary fibrosis patients with nosocomial pulmonary fungal infection. Methods50 pulmonary fibrosis patients with nosocomial pulmonary fungal infection were chosen as the observation group. In the same time,50 pulmonary fibrosis patients without nosocomial pulmonary fungal infection were chosen as the control group. The following factors were compared: hospital stay, corticosteroid use, antibiotic use, invasive procedures, a merger of the underlying disease.ResultsThere were 46％ (23/50) patients had long-term use of antibiotics in the observation group, much more than the control group(26％ ,13/50) ,the difference was statistically significant( P ＜0.05) ;More than half of patients in both groups using glucocorticoids, the ratio in the observation group was 84％ (42/50), which was significantly higher than the control group( P ＜ 0.05) ; In the observation group, the rates of patients with long time hospitalization ( ≥30 days), received invasive procedures, and associated with underlying diseases were much higher than the control group( all P ＜ 0.05). ConclusionMultiple risk factors could lead to the occurrence of pulmonary fibrosis patients with nosocomial pulmonary fungal infection,and the positive and effective preventions and standard treatment should be taken.

Objective:To explore the clinical application of permanent needle of deep venipuncture in early management of extensive burn.Methods:88 patients with extensively burn are analyzed.Results:The success rate of venipuncture was 96%.The effect was satisfactory,while the complication was less.Conclusion:The permanent needle of deep venipuncture shows an important role in early management of extensive burn.

Primary central nervous system lymphoma (PCNSL) is a rare type of extranodal lymphoma, and its incidence rate is increasing nowadays. Chemotherapy is the main means for treatment of PCNSL and the efficacy of high-dose methotrexate (HD-MTX) has been confirmed among those chemotherapeutics. Treatments of HD-MTX combined with other drugs have been studied extensively. Progress of HD-MTX and other drugs for PCNSL are reviewed in this article.

Objective To establish the scientific, rational and standard librarian performance appraisal index system in academic library in order to adjust their working behaviors, improve their service quality and increase the overall performance of library.Methods The current librarian performance appraisal situation was investigated according to the literature and on the field inspection.The appraisal indexes and their weight were established by Delphi and step analysis.Results The 3-scale appraisal index system was established, which include 4 No.1 indexes, 10 No. 2 indexes, and 59 No.3 indexes with their weight and score displayed.Conclusion The performance appraisal index system we established can effectively arouse the enthusiasm of librarians in scientific research innovation, manage-ment or social work.

Objective To study changes of serum enzymes among acute mesenteric vasculopathy (AMV) and several surgical acute abdomens for early diagnosis of acute mesenteric vasculopathy.Methods Rabbit models were established for acute mesenteric artery ischemia,acute mesenteric venous ischemia,acute mechanical ileus,acute strangulated intestinal obstruction,acute gastric perforation,acute pancreatitis,sham group,blank control group.Serum enzymes were tested after 0,1,3,6,9 h.Result Compared with blank control,acute mesenteric vasculopathy experienced significantly alterations of the serum enzymes.ALT (alanine aminotransferase),ALP (alkaline phosphatase),r-GT (glutamyl transferthe enzyme) were significantly higher after mesenteric veins blocked 3 hours,LDH (lactate dehydrogenase) was significantly higher after mesenteric venous blocked 6 hours (P ＜ 0.05).ALT was significantly higher after mesenteric artery blocked 6 hours (P ＜ 0.05).Elevated ALT were statistically different in acute mesenteric vasculopathy compared with blank control,sham group,gastric perforation,mechanical ileus,and strangulated intestinal obstruction (all P ＜ 0.05) ; r-GT level was statistically different between acute mesenteric artery ischemia and acute mesenteric venous ischemia.Conclusions Mesurements of serum enzymes level are helpful to make early diagnosis of acute mesenteric vasculopathy.

ObjectiveTo study the correlation between blast lung injury (BLI) and acute posttraumatic stress disorder(PTSD) through the establishment of the model about blasting injury of rats.Methods84 SD male rats were randomly divided into four groups:the normal control group( A),the model groups ( B,C) and the sham model group(D).21 rats in each group.The chest of the model group and sham model group rats,respectively,were exposed to 8＃ instantaneous electric detonator at different distances.Then,emotion and behavior of rats was observed through open field test and elevated plus maze test,at day 1,14,28 after blasting.Group A was not given the explosion of stress treatment.After testing,each group was randomly picked up seven rats for succumbing to draw blood which was used to detecting the level of plasma corticosterone by radioimmunoassay,respectively.Results( 1 ) On day 1,it was a significant difference that the latency time ( LT),crossing frequency (CF),rearing frequency(RF) and modification frequency(MF) which were both group B( (25.34 ± 4.50)s,( 19.73 ± 11.10 ),(0.52±0.11),(0.53±0.21) respectively)and group C((22.13 ±6.54)s,(28.67 ±7.22),(1.07 ±0.26),( 0.89 ± 0.15 ) respectively ) were compared with group A,including LT,CF and RF of group D ( ( 23.71 ± 3.9 ) s,(25.13 ± 12.35 ),( 1.26 ± 0.74 ) respectively ) (P ＜ 0.05 ).Then,on day 28,although there was a significant difference which both the LT,CF and RF of group B,and the CF and RF of group C were compared with group A(P ＜ 0.05 ),no significant discrepancy was observed between group B and C (P ＞ 0.05 ).( 2 ) In the elevated plus maze test,the result was similar to the open field test.(3)On day 1 after blasting injury,it was significant distinction that the level of serum corticosterone of group B,C and D (( 153.15 ± 44.50) ng/ml,( 132.72 ±78.77)ng/ml,(96.16 ±8.96)ng/ml respectively)were higher than group A(P＜0.05).Finally,the level of serum corticosterone of group B,C and D were lower than group A on day 28 (P ＜ 0.05 ).ConclusionBLI model successfully induces acute stress disorder(ASD) of rots which behaved like anxiety,fear,hyperarousal and avoidance,and promots furtherly the development of ASD to PTSD,and establishes the modle of acute PTSD.

Objective To investigate the effect of intensive nursing intervention on the secondary infection in chemotherapy of elderly patients with lung cancer.Methods 168 cases of elderly lung cancer patients whose neutrophil ≤ 1.0×109/L during chemotherapy were randomly divided into two groups,namely,the intensive care group and the control group,with 84 cases in each group.The control group was given routine nursing of infection prevention,while the intensive care group was given intensified nursing for infection prevention.A contrastive analysis was conducted in terms of the incidence,clinical characteristics and the duration of antibiotic treatment of the two groups of patients with secondary infection.Results The secondary infection rate of the intensive care group was lower than that of the control group during chemotherapy.What's more,the duration of fever and treatment of the intensive care group was shorter than that of the control group,hence the patients were safe during infection period.The difference was statistically significant.Conclusions Strengthening the nursing intervention can reduce the incidence rate of secondary infection in aged patients with lung cancer,increase the tolerance of patients to chemotherapy and ensure the successful completion of the chemotherapy cycle,prolong the life span of the patients with an improved quality of life.
