Objective To explore the relationship between the clinical characteristics and laboratory examinations.Methods Retrospective analysis was performed on the clinical data in 172 patients diagnosed as infectious mononucleosis(IM)in our department recently.Results The onset rate was high from 3 to7 years old.The main clinical presentations included fever,neck lymphadenopathy,pharyngitis,hepatomegaly,and splenomegaly.Some patients accompanied with obvious sonorous.The occurring rate of the complications was 74.4%,especially deteriorated liver function was the most common,next came to the lung infection.The proportion of atypical lymphocytes raised in 73.3% cases.The positive rate of EBV-VCA-IGM was 65.1%.Myocardium ferment chart went up in 27.9% cases,Erythrocyte sedimentation rate increased fast in 61.6%,CRP gently got higher in 62.8%.However,the ratio of atypical lymphocyte and EBV-VCA-IGM positive or negative had little to do with the pathologic condition and complications in IM.Conclusions The clinical progress of most IM is benign and multiple organs can be involved with atypical clinical manifestations.Examination for atypical lymphocytes is an easy and effective means to screen IM.

Objective To investigate the clinical effects and significance of continuous intravenous infusion and sequential therapy in pneumonia in children.Methods 90 patients with pneumonia were randomly divided into the observation group and the control group,with 45 patients in each group,observation group received continuous intravenous infusion,the control group received sequential therapy.The expectoration and rales disappear time,chest X-ray and body temperature return to normal time,clinical efficacy were observed.Results The expectoration and rales disappear time,chest X-ray and body temperature return to normal time were longer than control group,which were significantly different (x2 =6.21,P ＜ 0.05),the total effective rate of observation group was 77.8％,the total effective rate of control group was 97.8％,the differences were statistically significant (t =3.58,4.62,6.18,7.01,all P ＜ 0.05).Conclusion The sequential therapy treatment pneumonia in children has better clinical effect,shorter hospital stay and worthy of clinical application.

Parpillary adenocarcinoma is the most common type of thyroid cancer with high probability of cervicel lymph node metastasis. Prophylactic neck dissection is not necessary for patients with clinical negative neck. Modified radical neck dissection is the standard for therapeutic neck dissection. The range of dissection remains controversial. Level Ⅰ is not included routinely, level Ⅱ is recommended. Dissection of level Ⅴ may cause malfunction of the neck and shoulder, clinical negative level Ⅴ for low-risk group can be avoided with close follow-up. Rountine central lymph node dissection tends to reduce the local recurrence. Selective neck dissection for thyroid parpillary adenocarcinoma needs more investigations.

Objective:To establish a microfluidic chip system for immunoassay.Methods:We use direct-writing laser micromachining technology to fabricate microfluidic chip,establish microfluidic chemiluminescence immunoassay system based on superparamagnetic microbeads,and use this system to detect alpha-fetoprotein. Results:We can complete the analysis within 20 minutes with 5?l sample or reagent,the linear range was 1-800 ng/ml with average intra-assay and inter-assay precision at 6.3% and 7.8%,respectively and average recovery at 94.3%. Conclusion:The microfluidic chip system is a time-saving,cost-low and convenient method for AFP analysis.

Vascular calcification is a common pathology frequently occurred in the process of atherosclerosis ,hypertension , diabetes,chronic kidney disease,vascular injury and aging,resulting in an increased prevalence of cardiovascular events. Along with the social aging process,the incidence becomeshigher,andthis attract more attention. This review summarized a series of our works on vascular calcification in recent years ,including the update concept of vascular calcification ,recent classification and mechanism,and the confusion and hope in experimental and translational researches. This article aiming to promote further studies on the mechanisms and prevention of vascular calcification.

In order to deal with huge work load of processing and reviewing applications,many personnels have been loaned from universities and research institutes to National Natural Science Foundation of China (NSFC) every year.This phenomenon has received much concern.In this paper,the features of NSFC loaned personnel model were analysed,and the necessity for and feasibility of improving the training function of NSFC by reforming current loaned personnel model were discussed.

Objective To study the evaluation of rational use level of drugs in medical institutions.Methods According to the specific requirements of rational use of drugs in medical institutions,a criteria system is established.And a rational use of drugs evaluation model of medical institutions is to be built on the theory of fuzzy evaluation,group decision making and the analysis method of multi-index evaluation.Results Based on the fuzzy evaluation and group decision making,a rational use of drugs evaluation model of medical institutions is presented in the paper and one example is used to show the feasibility and the effectiveness of the proposed model.Conclusion The rational use of drugs evaluation model based on fuzzy evaluation and group decision making can effectively accomplish the evaluation of rational use of drugs of medical institutions,and build the foundation for improving the rational use of drugs of medical institutions and improving the level of universal health care.

Objective To explore the interference situation of several diseases in the detection of treponema pallidum antibody by chemiluminescence method.Methods One hundred and ten samples of 9 kinds of different infectious diseases and 200 clinical random samples were collected.Three hundreds and ten samples were simultaneously detected by using the Abbott ARCHITECT i2000 automatic chemiluminescence immunoassay analyzer and matched reagents,and the Roche E602 automatic chemiluminescence instrument and its matching reagent.The samples of inconsistent results were confirmed by the gelatin particle agglutination test (TPPA).Results There were 5 samples with inconsistent results detected by two instruments,5 samples confirmed by TPPA were negative,and 4 cases were the samples of multiple myelome.Conclusion (1)Abbott ARCHITECT i2000 and Roche E602 have a good consistency in detecting treponema pallidum antibody;(2)for the patients of multiple myeloma,the interference may exist in detecting treponema pallidum antibody by chemiluminescence method,which may cause false positive results and needs to be vigilant in our daily work.

OBJECTIVE To study the washing effect of three different methods with the multienzymatic detergent to keep the surgical instruments moist.METHODS The surgical instruments which were selected within five days were washed by three different methods with the multienzymatic detergent to keep moist.The washing effect was compared by eyes and with 5 times magnifying glass and with OB test paper.RESULTS There were prominent difference to washing effect among three methods to keep the surgical instruments moist(P

Glucokinase (GK) is considered to be the key regulatory enzyme in glucose metabolism, whose activity changing will lead to glucose metabolic disturbance and diabetes. Recently, people have realized that there is a good extensive perspective in diabetes research by means of glucokinase investigation. In this paper, we review the mechanism of diabetes resulting from abnormality of glucokinase activity and the status of glucokinase activators, propose the viewpoint that glucokinase is a powerful target for diabetes therapy and research, and illuminate that searching of glucokinase activators is the guidance in the future.
