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.

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.

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 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 efficacy of endoscopic sinus surgery (ESS)-based multidisciplinary therapy for patients with chronic rhinosinusitis (CRS), nasal polyps and bronchial asthma. METHOD: The study included 32 patients with CRS, nasal polyps and bronchial asthma who received ESS, besides surgery, who also used glucocorticoid inhalation, nasal spray and nasal irrigation perioperatively. The evaluation of the treatment was performed 3 years post after ESS. RESULT: In the 32 cases treated with ESS, 19 cases were cured, 9 cases were improved, 4 cases were inefficient by the treatment. The cure rate was 87.5%. The asthma symptoms were improved in 9 patients (P < 0.01), compared to 2 before surgery. The numbers of patients with improved symptoms were increased from 2 before the surgery to 9 after the surgery. CONCLUSION As the main treatment, endoscopic si- nus surgery was effective on CRS with asthma.

To improve the humanism education in civil undergraduate students management among the military university,to set up management model of humanism we should transform idea,embellish the environment,take efficient inspiring measures,establish scientific assessment system and enhance the manager's comprehensive quality,so that we can achieve the progressive development of civil undergraduate management among the military university.

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.

BACKGROUND:Although tumor stem cel s and their differentiated vascular cel s, which are not sensitive to chemotherapy and molecular targeted therapy, reduce overal blood supply of the tumor, these cel s facilitate the invasion and metastasis of the tumor, eventual y resulting in treatment failure. OBJECTIVE:To investigate the effect of gastric cancer stem cel s in stomach cancer invasion and metastasis as wel as its mechanism in angiogenesis. METHODS:A total of 20 gastric cancer stem cel s and 20 normal gastric cancer cel s SGC7901 were cultured in the medium with DMEM/F12 (1:1), 2%B27 and 20μg/L epidermal growth factors or cultured in 10%PBS, respectively. Invasion of gastric cancer stem cel s was detected by sphere formation assay, colony formation assay and Transwel invasion assay. Levels of mRNA and protein expression of CD44 and E-cadherin were measured to observe tumor metastasis. Besides, angiogenesis was observed by cel scratch test, Transwel migration assay and ring test. RESULTS AND CONCLUSION:Gastric cancer cel s adhered to the medium wal , and gastric cancer stem cel s suspended in the medium, which appeared to be spindle interstitial form. Number of gastric cancer tumor spheres was significantly lower than that of gastric cancer stem cel spheres in the sphere formation assay and colony formation assay (P<0.05). Number of gastric cancer stem cel s through the basement membrane was significantly higher than that of gastric cancer cel s (P<0.05). And the cel migration distance and ring number were significantly increased in the gastric cancer stem cel s as compared with the gastric cancer cel s (P<0.05). In conclusion, the invasion, migration and angiogenesis abilities of gastric cancer stem cel s are stronger than those of gastric cancer cel s, which can further promote the occurrence and progression of gastric cancer.

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.
