Objective To explore causes of fever in patients after the surgery for congenital heart disease(CHD), and put forward corresponding prevention and control measures.Methods Clinical data of patients undergoing sur-gery for CHD in the department of pediatric surgery of a hospital between January and May 2013 were analyzed ret-rospectively,the whole process of operation and postoperative nursing were observed,environmental hygiene moni-toring was performed at the same time.Results 26 patients all had fever after operation,fever in 21 cases (80.77%)was caused by non-infectious factors,5(19.23%)by infectious factors (ventilator-associated pneumonia in 4 cases,type I incision infection in 1 case).6 cases were absorption fever,20 were abnormal fever,difference in patients’age,duration of invasive manipulation (ventilator,urinary catheter,gastric tube)between two groups of patients were all statistically significant (all P <0.05),patients in the absorption fever group were with older age and short invasive manipulation time.Bacteriological detection rate in 26 patients was 76.92% (n=20),a total of 58 specimens were detected,7 were positive (from sputum specimens of 4 patients),5 isolates (71 .43%)were Pseudomonas aeruginosa .A total of 52 environmental specimens were collected for detection,the qualified rate was 80.77% (n =42).Conclusion Non-infectious factors are the main causes of postoperative fever in patients with CHD,health care workers should enhance the awareness of sterilization,standardize all kinds of medical manipula-tion,and reduce postoperative fever.

Intraocular lens ( IOL) implantation is the major method to replace the cataract lens. How to improve the biocompatibility of IOL has been the focus of current research. Major reactions after the IOL implantation include endophthalmitis, corneal endothelial edema, iritis, uveitis, and posterior capsule opacification, etc. At cellular level, macrophages, monocytes, fibroblasts and lens epithelial cells can be detected on the surface of IOL. Their adhesion, proliferation migration, and transformation may be induced by the operation related cytokines released into the aqueous humor. Detailed analysis of cytokines profile after IOL implantation may be beneficial to explore the mechanism of posterior capsule opacification.

Objective To explore the relationship between the microsatellite markers on chromosome 6 and the phenotypes of atopy. Methods Sixteen microsatellite markers on chromosome 6 were evaluated in 20 affected sib pair and trios families. Linkage disequilibrium analysis was conducted according to asthmatic phenotypes (total IgE, skin prick test, bronchial hyper responsiveness and eosinophil) by ETDT software system. Results Significant P value( P

AIM: To explore the mechanism of the therapeutic effect of hypobaric hypoxia on allergic asthmas guinea pigs. METHODS：After the model of asthma was established with ovalbumin(OA) challenge in OA sensitized guinea pigs, the animals were randomized into the asthmas group(AG), the alleviative group(ALG) and hypobaric hypoxia treated group(HHTG). The levels of plasma cortisol and endothelin(ET), ET in bronchoalveolar lavage fluid(BALF) were determined by radioimmunoassay. The pulmonary pathological changes were observed with optical microscope. RESULTS:(1) Infiltration of eosinophils (EOS) in alveolar septum was found in AG and ALG, while it was reduced in HHTG. (2) The level of plasma cortisol was significantly higher in AG than in normal control group(NCG) (P＜0.01).But it was significantly lower in ALG than in NCG(P＜0.01), there was no difference in plasma cortisol level between HHTG and NCG. (3) The content of ET in plasma was significantly higher in ALG than that in NCG, AG and HHTG(P＜0.01), and ET level in BALF was significantly higher in AG than that in NCG, ALG and HHTG(P＜0.05),however, no significant difference was found among the latter three groups, respectively. CONCLUSION: After the treatment with hypobaric hypoxia, the ET levels of the plasma and BALF were decreaced and the content of plasma cortisol was increaced, and infiltration of EOS in alveolar septum was decreaced in asthmatic guinea pigs.That may be one of the mechanisms by which hypobavic hypoxia prevents and cures asthma.

The fulfillment of the university's macro-policy lies in the teaching management at the departmental level, so it is essential to examine the status quo of departmental management and seek its rationalization and standardization. To restructure the managerial system, to bring to full play the academic management and to improve managers' competence prove to be the effective ways for enhancing the teaching management at the departmental level and the quality of education.

Hepatitis B virus is a serious hazard to human health, and the research and development of anti-hepatitis B virus drugs have become hot topics in the world. Based on the literature at home and abroad, the recent progress of anti-hepatitis B virus agents is reviewed in this paper, including structure characteristics, antiviral mechanism, in vitro and in vivo activity evaluation, and clinical application. Furthermore, the opportunities and challenges for anti-hepatitis B virus drugs in China are prospected.

Objective To investigate the changes of plasma adrenodullin(ADM) and C-type natriuretic peptide(CNP) level in children with chronic heart failure(CHF) and its clinical implications.Methods Forty-two children with CHF were collected.The patients suffered from dilated cardiomyopathy,congenital heart defects,and other heart diseases.According to a modified scoring system described by Ross and Reithman,16 patients were classified as class Ⅱ,14 as class Ⅲ,and 12 as class Ⅳ.Plasma levels of ADM and CNP were measured by radioimmunoassay assay in these patients and 11 healthy children.Echocardiography was performed to measure left ventricular function and the ratio of E/A.Results Plasma ADM and CNP levels of CHF patients were significantly elevated as compared with those of the control subjects [(218.27?106.53) ng/L vs(74.39?53.99) ng/L,P=0;(190.27?108.38) ng/L vs(92.59?(59.46) ng/L),P0.05).ADM levels were elevated with the advancing severity of CHF determined by a modified scoring system described by Ross.However,the plasma CNP levels in the normal state wasn′t significantly different from those observed in class Ⅱ.Likewise,the plasma CNP level in the class Ⅲ was not significantly different from that observed in class Ⅱ.Conclusions ADM and CNP might play a compensatory and defensive roles in the pathophysiology of the pediatric CHF.ADM may be a biochemical marker for evaluation the severity of the chronic heart failure in children,but also a new prognostic indicator of this syndrome.

Objective To discover the role of interleukin-18(IL-18) and CD_(54) in congestive heart failure(CHF),and evaluate the diagnostic value of IL-18 and CD_(54) in CHF.Methods Blood samples were collected from 52 children with CHF,included 18 cases in classⅡ,17 cases in class Ⅲand 17 cases in class Ⅳ.Fifteen healthy children were normal control group.The levels of IL-18 was(detec-)ted by ELISA method and the expression of CD_(54) was examined by flow cytometry.Results The levels of IL-18 and CD_(54) in CHF were significantly higher than those of control subjects(P0.05),but the levels were respectively significantly higher than that of control subjects(P

AIM: To investigate the postoperative changes of binocular visual function in patients with congenital superior oblique palsy.METHODS: Eye position and binocular visual function were examined in 28 patients with congenital superior oblique palsy pre- and post-operatively. The results were statistically analyzed.RESULTS: The normal eye position rate after operation was 89.3%. There were 9 patients who gained simultaneous perception after operation, while 13 patients gained fusion as many as that gained stereoacuity. There was statistically significant difference between postoperative and preoperative eyes (P<0.05). Near stereoacuity was improved after operation. Patients who had better visual acuity and low strabismus degrees as well as fusion had a better recovery.CONCLUSION: The operation could improve the eye position and rebuild the binocular visual function of the congenital superior oblique palsy. The recovery of binocular visual function was related to visual acuity and strabismus degrees of the patients and whether they had fusion function.
