Caffeine is a methylxanthine alkaloid compound,which is not only effective,but also safe and needn't monitor the plasma concentration for the prevention and treatment of apnea in preterm infants,compared with theophylline.In recent years,it has been reported that caffeine is beneficial to improve weaning extubation success rate,reduce the incidence of bronchopulmonary dysplasia in preterm infants,reduce the risk of surgical closure of patent ductus arteriosus,and improve the long-term neurological outcome in preterm infants.

Signal transduction is a very fine and complicated process that indudes participation in the cell propagation, division, maturation and apoptosis.Under normal circumstance disabled-2( Dab2) in human tissues participates in the signal transduction of the cell in order to allow the body to keep normal functions,but under some circumstances the absence of Dab2 influences the normal signal transduction path,leding to atypical cell changes.and the generation of tumors.This paper is a review on the construction and function of Dab2 and its related gene as well as the relation of Dab2 and tumors generation.

Objective:To detect the levels of T help cell 17 (Th17)/regulatory T cell (Treg) in the peripheral blood of patients with ovarian cancer and explore their clinical significances.Methods:55 patients with ovarian cancer and 60 normal controls were enrolled.The percentage of Th17/Treg cells were detected by flow cytometry (FCM).The expression of retinoid-related orphan receptor gamma-t ( RORγt)/foxhead winged-helix box protein 3 ( Foxp3) mRNA was measured by real time PCR and the plasma levels of IL-17/TGF-β1 were detected by enzyme linked immunosorbent assay (ELISA).Results: The percentage of CD4+IL-17+/CD4+T cells,the mRNA expression of RORγt and the plasma levels of IL-17 increased significantly in patients with ovarian cancer than in normal controls (P<0.05).Compared with normal controls,the percentage of CD4+Foxp3+Treg/CD4+T cells,the mRNA expression of Foxp3 and the plasma levels of TGF-β1 increased significantly in patients with ovarian cancer ( P<0.05).Conclusion:The imbalance of Th17/Treg cells may exist in the peripheral blood of patients with ovarian cancer.Th17/Treg cells may participate the pathology of ovarian cancer.

Open-path Fourier transform infrared ( OP/FT-IR) spectra were analyzed with target factor analysis ( TFA) and band-target entropy minimization ( BTEM) respectively, with the purpose to reconstruct spectral characteristics of target molecules from matrices of spectra. Five sessions of continuous OP/FT-IR monitoring were carried out around farms. For each session, the spectra were arranged row-wisely in order of measuring time, which yielded five matrices for data analysis. Results showed that both BTEM and TFA could reconstruct spectral characteristics of target molecules from the spectral data matrix, but the performance of the two methods differed slightly. TFA can retrieve spectral features of target molecules in the presence of interferences, and the reconstructed spectra are similar to corresponding reference. BTEM can implement such spectral retrieval without the reference spectrum. This work presents not only the application of BTEM method to qualitative analysis for OP/FT-IR spectra, but also a thorough comparison between the two methods. The conclusion is helpful to qualitative analysis of complex multi-component systems.

With the development of breast-conserving surgery,the problem of local relapse after conservation therapy became a hot spot for discussion.There was much research done on the influential factors of recurrence after conservation therapy,however,there is little research on the strategy for salvage of relapse.This review summarizes the recent research on the diagnosis,treatment and prognosis of local recurrence of breast cancer after conservation therapy.

Objective To sum up the observation points and nursing measures for patients with subclavian steal syndrome after stent implantation,improve the predictive nursing and reduce the occurrence of postoperative complications. Methods Reviewed and summarized the nursing process and experience of 19 cases after stent implantation. Included prevention from complication, discharge guidance,the close observation of vital signs and the changes of disease. Results All 19 patients were cured after stent implantation and no serious complication occurred. Conclusions Endovascular stenting is an effective way for the treatment of subclavian steal syndrome. meticulous nursing and prevention of complications can ensure the success of surgery in the process of treatment .

Objectives: To explore the epidemiological distribution of body mass index(BMI),waist to hip ratio(WHR) and abdominal circumference in population of Nanjing,Jiangsu Province. Methods: BMI, WHR and abdominal circumference were measured on 3 445 healthy cases aged 18～90 of Nanjing. Epidemiological distribution of BMI,WHR and abdominal circumference were analyzed according to sex and age. Results:The total mean BMI was( 23.28 ?3.49)kg/m 2, and the BMI in male was higher〔(23.80?3.36)kg/m 2〕 than that in female 〔(22.25? 3.49)kg/m 2〕( t =12.75, P

Objective To explore the diagnostic value of ultrasound-guided aspiration biopsy in patients with unexplained refractory ascites.Methods The data of 25 cases of unexplained refractory ascites were retrospectively analyzed.For all the cases the diagnosis was based on the examination of contrast enhanced CT or ultrasound.Ultrasound-guided aspiration biopsy of locally thickened peritoneum or ti- ny masses in ascites was performed.Reults Ultrosonographic image of all cases was as follows.10 cases,with locally thickened peritone- um,were isoechoic or hypoechioc.In 2 of 10 cases contrast enhanced ultrasound examination was done,and the images were characterized by an obvious enhancement in arterial phase and quick wash-out in veinous phase.In 7 cases there was irregularly thickened peritoneum, accompanied by adhesion and caking of the omentum.Cystic formation in ascites or in peritoneum was found in 5 cases.Solid mass in asci- tes was found in 2 cases,and splenomegaly and enlarged pancreas were found in 1 case.Ultrasound-gnided aspiration biopsy was perfomed in all the patients.Among them 4 patients were operated on later.Histopathologic examination showed malignency in 20 patients.Among them,malignant peritoneal mesothelioma accoumted for 6 cases,pancreatic cystoadenoma in 2,mestastic adenocarcinoma in 9,malignant schwannoma in 1,lymphoma in 1,and histiocytoma in 1 patient.In the other 5 cases the lesion was benign,and it was verified by follow- up for about 6 months.Among them there were 3 cases of tuberculosis,1 case of inflammatory disease and 1 case of retroperitonesl fibro- sis.Conclusion Ultrasound-guided aspiration biopsy is valuable in the diagnosis of locally thickened peritoneum and tiny mass in ascitic fluid,and is valuable for diagnosis of unexplained refractory ascites.
