Integrin is a kind of crucial adhesive molecule on the membrane,and it exerts its function through activating its intra-cellular effectors.One of the most important effectors is integrin-linked kinase (ILK),which is a serine/threonine protein kinase located in focal adhesions and has a key position in transducing many of the biochemical signals.It plays an important roles in regulating fundamental processes such as cell-matrix interactions,growth,proliferation,survival,differentiation,migration,invasion and angiogenesis under both physilogical and pathological processes.

Based on the language problem and cultural background difference of foreign medical students,we applied Problem-based Learning in their pediatric clinic probation teaching. This method could raise students learning activeness,enhance self-teaching ability and cultivate individual clinical thinking,which is a beneficial trial in medical foreign students educational practice.

In the clinical practice of foreign students in neonatal department,the experimental group followed PBL method,while the control group took traditional "master and disciple" way. The performance records of the clinical examination and questionnaire findings are significantly different between the two groups,which confirms that PBL is a good method to be widely used in the foreign students'pediatric clinical practice.

The article is to study the status of academic communications,providing useful exploration to enhance the scientific research ability of postgraduate students.In the base of summing up the forms of the internal and external multi-level academic communications,we point out varies of problems existing inall levels.The level and publicity of some academic communications are poor; the postgraduate students' participation is not powerful enough; the guide form supervisors and graduate management are in shortage. These factors are restricting the role of academic communications in training postgraduate's research ability.Therefore,we should take some appropriate improvements.The effect of academic communications in training graduate students' research ability should be enhanced via improvements at various aspects.

Objective To analyze the clinical effects of bronchoscope combined with hot and cold ablation in treatment of benign and malignant tumors in primary tracheal and bronchial. Methods From January 2013 to November 2015, 30 cases of pathological types of primary tracheal / bronchial benign and malignant tumors patients include: 8 cases of hamartoma, 1 case of lipoma, 4 cases of granuloma, 1case of clear cell carcinoma, 7 cases of small cell lung cancer, 9 cases of squamous cell carcinoma, were treated by using carbon dioxide cryotherapy combined hot ablation under bronchoscope. Then investigated the outcomes. Results 30 patients, 22 males, 8 females, suffered from 1 month to 2 years, underwent surgery bronchoscope interventional treatment under local anesthesia combined with intravenous anesthesia, are taking joint cold ablation technique. All patients airway is completely opened, the lifting of the airway obstruction. Including 19 cases of disposable surgical removal of the lesion; 8 cases of lesions due to wide distribution, 2 times surgery; three cases three times surgery, no serious complications, follow-up without recurrence, blood gas analysis and dyspnea index were significantly improved. Conclusion Bronchoscope cold joint ablation techniques in the treatment of primary tracheal, bronchial benign and malignant tumors is effective, simple, minimally invasive and safe.

Phosphatase and tensin homology deleted on chromosome 10 (PTEN) is a tumor suppressor with dual protein and lipid phosphatase activity.PTEN is involved multisystem diseases and cancer,though the mechanisms of PTEN regulation are far from clear.Recent advances concerning regulation of PTEN including protein-protein interaction,phosphorylation,ubiquitination,oxidation and acetylation will be discussed.

Objective To discuss the common nature of live depression and spleen qi deficiency and liver disease and the changes after the intervention ofXiaoyaopower by the metabonomics method. Methods A total of 40 rats were randomly devided into the normal control group, the liver depression and spleen qi deficiency model group, the liver depression and spleen qi deficiency treatment group, the liver disease group, the liver disease treatment group, 8 in each group. The liver depression and spleen qi deficiency model rat was established by tail-clamping infuriation and Senna gavage method, and the liver disease model rat was established by the CCl4-induced liver injury method. The rats of the liver depression and spleen qi deficiency treatment group and the liver disease treatment group were given 2 g/mlXiaoyao powder, and other groups were given the equal-volume saline. All the treatment lasted 28 days. Twelve hours after the last administration, rat metabolite profiling and contents in the serum were detected by GC-MS, the change of rat liver tissue was observed through HE staining.Results The rats of liver depression and spleen deficiency pattern and liver disease model group appeared liver cell nuclei atrophy, dissolution, degeneration necrosis and lymphocyte infiltration, and at the same time the contents of Glycine, Butanediodic acid, Propanoic acid, Methionine, Glutamine, Phenylalanine in serum were all higher than the normal control group (P<0.05). AndXiaoyao powder could reduce the content of the contents of Glycine, Butanediodic acid, Propanoic acid, Methionine,Glutamine, Phenylalanine in serum (P<0.05).ConclusionXiaoyao powder may play the role of protecting liver by the regulation of one carbon unit, sulfur containing amino acids, aromatic amino acids and amino acid of special metabolism and three tricarboxylic acid cycle.

We reported a case of pulmonary capillary hemangiomatosis (PCH) and introduced its diag-nosis, differential diagnosis, pathogenesis and development of treatment based on the review of Dana Point 2008 Classification of Pulmonary Hypertensiona and current literatures .A 43-year-old female presented progressive dyspnea, elevated pulmonary arterial pressures and CT pulmonary angiography (CTPA) imaging of main pulmonary arterial enlargement and wide spread ill -defined centrilobular nodules of ground-glass opacity.Her histologic features were proliferation of capillary channels within alveolar walls as well as muscularization of arterioles and medial hypertrophy of muscular pulmonary arteries.The treatment with diuretics and warfarin was used promptly , but unfortunately was ineffective. The patient died three months after diagnosis .PCH is a very rare vascular disease with poor prognosis . The diagnosis of PCH rests on the integration of clinical and radiographic information with pathologic fea -tures, however pathology is the most reliable means .Because clinical symptoms, imaging and histological features of pulmonary veno-occlusive disease (PVOD) and PCH broadly overlap, differential diagnosis should be made carefully.Among the various pathologic features proliferation of capillaries within alveolar walls is the key point for diagnosing PCH , which is also the most critical criteria for differentiating PCH from PVOD.So far the only definitive treatment for PCH is lung transplantation , without which the pa-tient will die several months after diagnosis .
