Objective To explore the changes of asphyxial neonatal gastric juice pH values,and to provide data for making early intervention measures.Methods Eighty asphyxial neonates were divided into routine group(55 cases)and intervention group(25 cases).Twenty neonates who weren't asphyxial were set as a control group.Those neonates' gastric juice pH values were monitored dynamically.The newborns in intervention group were treated by giving smecta and cimetidine intravenously on the routine treatment.The impairment occurrence conditions of these newborns' gastrointestinal functions were observed.Results The gastric juice pH values of asphyxial neonates were obviously lower than those of the control group at their birth(Pa0.05).The occurrence rate of gastrointestinal functions impairment was lowered(?2=16.0 P

AIM: To investigate the effects of pioglitazone on corneal neovascularization(CNV)induced by alkali burnin rats and on expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (b-FGF).METHODS: CNV was induced by alkaline burn in rats which were then administered pioglitazone subconjunctivally.Corneal angiogenesis was evaluated and observed with a slit lamp microscope and the VEGF and b-FGF level were determined by immunohistochemistry and Western blot at different intervals.RESULTS: The CNV of the rats was shown two days after alkaline burn, and reached its highest level in 7-10 days. The mean values of the area and length of neovascularization and the VEGF and b-FGF levels in the pioglitazone-treated group were significantly lower than those in the control group at various time.CONCLUSTON: Local application of pioglitazone could remarkably inhibit CNV, probably by means of downregulation of VEGF and b-FGF expression.

Objective To observe the changes of type 2 diabetes mellitus patients in blood sugar,TC,TG,HDL C,plasma insulin,body mass index(BMI), microalbuminuria,etc before and after moderate intensity exercise training.Methods 28 patients with mean age of 59.0?7.6 years did moderate intensity exercise training for 1～1.5 hours every day for 12 month.At the same time they received the treatment of diet and oral antidiabetic drug com pared with 40 controls without exercise training. Before and after the observing period we measured the values of items above.Results Plasma glucose level , HbAlc,AUCGS(the area under the curve of glucose sugar) and BMI in fat diabetes with training team were obviously decreased compared with those before observation( P 0.05).Conclusion Exercise training can significantly descend blood sugar, insulin resistance and BMI of obese people ,improve lipidmetabolism and ascend insulin sensitivity. So the action of exercise can't be replaced by the diet and oral drug.

With the development of immunoassay and sensing technologies and the solid waste compost technologies being paid more and more attention,the method of immunosensor can’t be interfered by some interference factors of the commonly used analytical methods,it is of great significance to apply the immunosensor technologies in monitoring,and real-time,online measurement during compost process. The working mechanism and classification of immunosensor are briefly introduced,and the components of the complex compost system are divided into solid phase,liquid phase and gas phase. The development and application of immunosensor in compost is introduced. The latest progress in immunosensor for determination of trace toxicants is reviewed. The application of immunosensor in environmental monitoring and its future development are also discussed.

Objective: To investigate the relationship between intercellular adhesion molecule-1 (ICAM-1) and the signaling pathway of vascular endothelial growth factor receptor-3 (VEGFR-3) in gastric cancer and explore the mechanism underlying the lymphatic metastasis of gastric cancer. Methods: Totally 100 grastic cancer patients were recruited in the study including 13 cases of early gastric cancer and 87 cases of advanced gastric cancer with lymphatic metastasis (50 cases) and without lymphatic metastasis (37 cases). Thirty cases of normal gastric mucosa in the distance of > 5 cm from gastric cancer lesions were used as controls. The expressions of VEGF-C, VEGF-D, VEGFR-3, ICAM-1 and lymphatic microvessel density (LMVD) were detected using immunobistochemical method (EnVision™). The lymphatic and vascular invasions of gastric cancer were observed by microscopy. Results: The positive expression rate of ICAM-1 was increased with The increase in infiltration depth. It was 0% in the control, 7.7% in early stage gastric cancer, and 31.0% in advanced gastric cancer, respectively (P < 0.05). The positive rate of ICAM-1 expression was related with lymphatic metastasis (P < 0.005), depth of tumor invasion (P < 0.025), VEGF-C expression (P < 0.025), and VEGF-D expression (P < 0.005). Logistic regression analysis showed that the positive expression of ICAM-1 correlated with lymph node metastasis and expression of VEGF-D (P = 0.001 2, P = 0.023 7). Conclusion: ICAM-1 expression has positive correlation with expression of VEGF-D. The mechanism may be contributed to regulation of ICAM-1 expression by VEGF-D via VEGFR-2 signaling pathway.

E2F transcription factor 1 (E2F1) is a major member of the E2F transcription factor family and participates in a wide range of physiological regulatory processes, such as cell cycle, survival, apoptosis, and metabolism. It is proved that the activity of E2F1 is related to the G1/S phase regulation of the cell cycle dependent on tumor suppressor retinoblastoma protein (RB). Recent studies have shown that E2F1 is highly expressed in prostate cancer cells, manifested as an oncogene, and its expression level is closely related to the occurrence, development, and poor clinical prognosis of prostate cancer. Androgen receptor (AR) is the main driving factor for the growth and progression of prostate cancer, and the changes of AR pathway play a key role in the pathological progression of prostate cancer. This article provide a systematic and comprehensive summary on recently published articles to review the role of the E2F1 pathway in prostate cancer.

Objective To investigate the characteristics of family environment in children with attention deficit hyperactivity disorder (ADHD) in clinics, and analyse the risk factors for ADHD. Methods Two thousand two hundred and ninety-six children with inattention, hyperactivity or unfavourable school performance were subjected to diagnosis with DSM-Ⅳ criteria in clinics. The characteristics of family environment were investigated by self-prepared questionnaires. The risk factors for ADHD were explored by univariate analysis and noneonditioned multivariate Logistic regression analysis. Results Seven hundred and twenty children were diagnosed with ADHD. There were significant differences in family environment between children with ADHD and those without(P<0.05 or P<0.01). The risk factors for ADHD included discord between parents, parental smoking and maternal depression during pregnancy and after delivery, while older age, female, paternal higher educational background were protective factors for ADHD. Conclusion Unfavourable family environment may be associated with the prevalence of ADHD, and special attention should be paid to the family environment in the treatment of ADHD.

Objective To study the simple preparation method and structure of nano-hydroxyapatite/collagen composite, to investigate new substitute of repairing bone for using in tissue engineering. Methods Porous nano-hydroxyapatite was made of Ca (OH)2 and H3PO4. Collagen was drawn from fresh adult bovine tendon. The two materials were prepared into biomembrane through the glutaraldehyde and freeze-drying. The crystallite phase, micro-morphology, structure, crystallite size of the composite were examined by XRD and scanning electronic microscop (SEM). Results The results showed that the composite structure was porous and consisted of nano-hydroxyapatite (10 nm ? 50 nm - 20 nm ? 80 nm) and collagen fiber. The crystallite phases and size of the composite was similar to that of natural bone. Conclusion The porous nano-hydroxyapatite /collagen composite is expected to be an ideal substitute of repairing bone.
