Fever in patients with severe craniocerebral injury was a frequent occurrence.The rate of fever patients lead to plant man or death high up to 28％-72％.The univariate analysis found that there was significant association between fever and motality.One of the common cause of fever was non-infectious fever,which related with craniocerebral injury,including central fever,dehydration fever,clonus and rebleading fever.The major complication was central high fever after servere craniocerebral injury.The temperature high up to 39 ℃,which aggravated the original basic diseases,lead to respiratory and circulatory failure.Another cause of fever was infection fever which associated with nosocomial infection.Serious disease,long hospiltal stay,high proportion of invasive operation,coma were the high risk factors of patients with craniocerebral injury.The major type of nosocomial infection were pudmonary infection and surgical site infection.By reviewing domestic and foreign literatures and expert consensus,this article was intended to explore the characteristics and mechanism of fever in patients with craniocerebral injury.In order to reduce the secondary brain injury,decrease the disability rate,increase the sutrvival rate,diagnosis and treatment should be taken early.

ObjectiveTo evaluate the retinal function with central serous chorioretinopathy (CSC) and the fellow eyes (mf-ERG).MethodsTwenty patients (40 eyes) with unilateral CSC, diagnosed by fluorescein angiography, were examined on each eye of the patients by mf-ERG multifocal electroretinography. The patients aged from 31 to 53 (13 men, 7 women; mean age, 41 years), and the CSC eyes had visual acuities of 0.2 to 0.8. None of the patients had significant abnormality in the fellow eyes with visual acuities of 0.8 to 1.5. Twenty-four healthy people (29 normal eyes with visual acuities of 1.0 and more and without any retinal diseases) were studied simultaneously as the normal control. The stimulus matrix of 61 hexagonal elements were grouped into 5 concentric rings from the fovea outward to 30? of the degree of visual field. The first-order responses of mf-ERG were recorded. The first negative wave (N 1-wave) and positive wave (P-wave) of the mf-ERG were measured. Amplitude intensities and latechies for the two configurations were calculated and compared.ResultsCompared with the control eyes, the responses were not only depressed severely in P 1- and N 1-wave amplitude intensities in the ring 1~3 in the CSC eyes with CSC (P0.05). There were no significant differences in N 1- and P 1-wave latencies in 5 concentric rings among the control eyes, the fellow eyes or the CSC eyes.ConclusionsCSC is a kind of macular disease involving both eyes. It may cause the decrease of retinal function in macular area of CSC eyes and also influence the retinal function in macular area of the fellow eyes. mf-ERG is a sensitive way in examining visual function.

OBJECTIVE To investigate pathogenic bacteria and prognosis of abdominal infection and take measures to prevent and control it.METHODS We analyzed the clinical material and prognosis of 31 patients with abdominal infection retrospectively according to the culture results of puncture and drain liquid from abdominal cavity from Nov 2007 to Nov 2008.RESULTS In 31 patients,5 were complicated with pulmonary infectionwhich the infection rate was 16.13%,and 7(22.58%) died.Totally 48 pathogenic strains were isolated from ascitic fluid culture,20 strains(41.67%) were Escherichia coli,11 strains(22.92%) were Enterococus.Some of coagulase-negative Staphylococcus,Streptococcus,Candida,Klebsiella pneumoniae,and Staphylococcus aureus were also isolated.The resistance rates of E.coli to cephalosporins were above 50.00%,to quinolones were above 65.00%.The susceptibility rates of E.coli to some ?-lactamases inhibitors and carbapenem were very high.The resistance rate of Enterococus to rifampicin was 63.64%,to piperacillin/tazobactam and piperacillin was 81.82%,to erythromycin was 100.00%.The susceptibility rates of Enterococus to teicoplanin,vancomycin,and linezolid were 100.00%.CONCLUSIONS The predominant pathogenic bacteria of abdominal infection are E.coli and Enterococcus.Abdominal infection tends to combine with pulmonary infection.The patients who got into multiple organ dysfunction syndrome have high mortality.

Objective To explore the relationships of self-esteem, implicit self-esteem and perfectionism in the depressed patients. Methods Both of the depression group (n=50) and control group (n=45) completed the self-esteem scale (SES), the self-acceptance questionnaire (SAQ), the Chinese Frost multidimensional perfectionism scale (CFMPS), the implicit association test and the Raven’s Standard Progressive Matrices. The implicit association test were performed before (pre-IAT) and after (later-IAT) the Raven’s Standard Progressive Matrices. Results The SES score was lower in depression group than in control group (P=0.002). To the IAT score, the interaction effect of group and time achieved no statistically different (P=0.735). The group main effect of IAT was significant (P=0.001). The IAT score was higher in de?pression group than in control group (P=0.013). The time main effect was significant (P=0.033). The pre-IAT was higher than later-IAT (P=0.007). The depression group had higher scores of concern over mistakes (P=0.007) and doubt about action (P=0.006) dimension of CFMPS, and lower score of parental expectations (P=0.038) dimension than the control group. The later-IAT was negatively related with parental expectations dimension and the total score of CFMPS in the de?pression group (P<0.05). Depressed patients’SES and SAQ scores were negatively related with concern over mistakes and doubt about action dimension and the total score of CFMPS (P<0.05). Conclusion The instability of implicit self-es?teem of depressed patients is associated with negative perfectionism.

Objective:To study the mechanisms of neutrophil elastase (NE) induced expression of respiratory mucin MUC5AC. Methods:Using gene recombination techniques,four luciferase reporter gene plasmids containing different length of human MUC5AC gene promoter were constructed.Site-directed mutagenesis technique was used to establish mutants of Sp-l and NF-?B site in MUC5AC gene promoter; the relative luciferase activities were detected in the transfected human pulmonary A549 cells. Results:Series of luciferase reporter gene containing different sequences of human MUC5AC promotor were constructed successfully.NE could increase the expression of luciferase reporter gene plasmid containing -1300bp,-689bp and-324bp version of MUC5AC promoter in the transfected A549 cells (P

Objective To study metabolism of polyunsantured fatty acid (PUFA) and to investigate the relationship between different PUFA compositions and △6 desaturase (D6D) activity in colorectal carcinoma (CRC).Methods Fresh frozen malignant CRC tissues were obtained from 61 patients and blood samples were detected in 38 patients.The PUFA composition in these samples was determined by gas-liquid chromatography on a capillary column.The fatty acid product-to-precursor ratios in blood and tissue as estimates of desaturase activity (D6D activity index),and its relationship with the ratios between different PUFA compositions were investigated.Results Metabolism of ω-6 PUFA dominated in PUFA metabolism path.The ratio of ω-6/ω-3 PUFA was 4.89 in blood samples and 10.15 in tissues.The ratio of LA/ALA was 101.92 in blood samples and 86.16 in tissues.The ratio of ω-6/ω-3 LC-PUFA was 2.86 in blood samples and 4.51 in tissues.The D6D activity index in ω-6 PUFA metabolic processes both in tissues (t =1 1.609,P =0.00) and blood samples (t =-9.151,P =0.00) were higher than that in ω-3 PUFA.Conclusion In colorectal carcinoma,the ω-6 PUFA metabolic not only plays an important role in the metabolism of PUFA,but also is more active than the ω-3 PUFA metabolic,and in some way links to the development of tumorigenesis in CRC.
