Select 106 pregnant women with threatened preterm labor between 28 and 37 weeks of gestation. They have been treated continually by the preventing preterm labor therapy including antibiotics and magnesium sulfate. Cervicovaginal fetal fibronectin (fFN) and C-reactive protein (CRP) in serum were detected before treatment and after 3-day and 7-day treatment respectively. 100 normal pregnant women were included as control group. (1) The fFN and CRP had significant differences between study group and control group (P<0.05). (2) The fFN and CPR were different compared in the treatment period (P<0.05). Fetal fibronectin and CRP can be used can be used in therapeutic effect evaluation of threatened preterm labor.

Objective: To investigate the expression ofVEGF-Aand the correlation with the sentinel lymph nodes lymphangiogenesis and its metastasis in non-small cell lung cance(rNSCLC).Methods: The expression of VEGF-A was detected in 65 patients with NSCLC by SP immunohistochemistay. The expression of LYVE-1 was detected by immunofluorescence. The new lymphatic vessel density was counted by LYVE-1 and analyzed with clinicopathologic parameters. Results: The positive rate of VEGF-A was 72.3%(47/65),which was positively correlated with sentinel lympha nodes metastasis(r=0.453,P

0.05).Conclusion:QDs show no effect on cytobiological behavior of living MG-63 cells.

Objective:Assessment ofthe value of B-type natriuretic peptide levels combines TIMI risk scores in predictinglate mortality in patients with ST-segment Elevation Myocardial Infarction(STEMI).Methods:345 patients with STEMI were studied.Blood was drawn and the plasma concentration of BNP was determined within 24 hours after the onset of chest pain and the patients'TIMI risk score was measured.The all-cause mortality,including cardiac and non-cardiac deaths during Long-term follow-up,was recorded.Results:Mortality was 20.0%(n=69)during a follow-up of 314?208 days.The late mortality was related to higher TIMI risk scores(P;P

MIC,according to which,the antibiotics frequently used for treating respiratory infections were divided into three groups:Time-dependent(with minimal or no PAE),Concentration-dependent(with PAE),Time-dependent and Concentration-enhanced(with PAE),In addition,the most appropriate antibiotic administration methods are also explored respectively in the article.Finally,several measures of preventing emergence of resistance are proposed based on the theory of MPC.

Dengue virus receptor is one of the hot issues in the investigation of dengue virus.The structures of many receptors,such as proteins,Fc-R,heparin sulphate and LPS/CD14-associated binding proteins,have been confirmed.Recently,great progress has been made in the research of some special receptors found in cells suseptible to dengue virus,and protein compositions binding to the virus membrane domain have been isolated from several susceptible cell lines.The candidates for the composition of the receptor can be catergorized into heat-shock protein,glucose regulated protein,laminin receptor,DC specific ICAM-3 grabbing non-integrin,etc.This article reviewed the recent advancements in the study of dengue virus receptors.

Objective In order to investigate the ability of flow cytometer (FCM) to diagnose malignant tumor and evaluate prognosis of tumors in salivary glands, the DNA ploidy and cell cycle had been analysed and the association of these parameters with histologic grades, lymph node metastasis were studied. Methods The fresh tissues of benign tumor, mixed tumor and malignant tumor were detected by FCM. Results DNA aneuploid has not been detected in benign tumors; 44 cases of mixed tumor has been detected with DNA aneuploid nd with high SPF; it suggests that these cases have malignant trend; most of malignant tumor were detected with high aneuploid. DI was not correlated with lymph node metastases, but correlated with histologic grades (P

With conventional double-antibody sandwich technique,total IgE level in35 serum samples from malignant lymphoma patients and 35 matched normalcontrols was measured by ELISA.It was found that there was a statisticallyhigher total IgE levels in patients than in the control(p

Pathological changes of Kupffer cells in number and ultrastructure were studied by means of colloidal carbon uptake, endogenous peroxidase cytochemistry, quantitative histology and ultrastructural stereologic morphometry at various time intervals (3,7,14,21,and 28 d) after common bile duct ligation. Kupffer cell phagocytic function and serum fibronectin opsonic activity were measured. The results show the morphological changes of Kupffer cells coinciding with their functional alterations. Alteration of Kupffer cell phagocytic function is mainly due to the changes of number and cellular activity of Kupffer cells.

0.05).The expressions were remarkably of endometrial ER、VEGF and KDR in the study group as extremely lower than those in the control group,and the statistical difference between the two groups were all significant(P0.05).Conclusion:ER、VEGF and KDR may be relevant to the occurrence of hypomenorrhea.
