[Summary] When accompanied with pulmonary disease ,the lung functions of diabetic patients usually represent decreases of diffusing capacity ,ventilation function ,bronchomotor tone and respiratory muscles. The mechanisms of lung damage may include non‐enzymatic glycosylation of proteins ,oxidative stress ,IR ,local defensive ability change ,and autonomic neuropathy. Diabetes mellitus is a risk factor for lung function damage ,and lung function damage is an independently predictive factor of diabetes mellitus. The change of lung function in diabetic patients is associated with age ,duration ,blood glucose level and complications.

Cyclin E is expressed starting from the middle G1 phase of the cell cycle,and is accumulated in the G1/S boundry.Cyclin E binds to and activates the cyclin-dependent kinase CDK2.Cyclin E-CDK2 complex initiates a cascade of events that leads to DNA replication by phosphorylating its substrates,such as Rb,CDC6,NPAT and P107,etc.Additionally,cyclin E plays an important role in the regulation of genomic stability,spindle-organizing structure and centrosome cycle.Cyclin E expression is trans-activated by members of the transcription factor E2F family and degrades via the ubiquitin-proteasome pathway.At the same time,it is also negatively regulated by the CIP/KIP proteins.Cyclin E highly expressed in the initiation and progression of different human cancers,such as breast cancers,lung cancers,leukemia,lymphomas and others.

Objective To study the change of serum procalcitonin(PCT) expression level and to investigate its clinical value for predicting the prognosis in the patients with severe acute pancreatitis (SAP) .Methods Totallay 48 inpatients with SAP in our hos‐pital from April 2012 to April 2014 were retrospectively analyzed .The PCT levels during different hospitalization period in the sur‐vial group and the death group were detected and analyzed .The scores of acute physiological and chronic health evaluation Ⅱ (A‐PACHE Ⅱ) were compared between these two groups .Results (1)The clinical characreristics of gender ,body temperature and WBC had no statistically significant differences beween the survival group and the death group (P>0 .05) ,but the PCT level had statistical differencet (P<0 .05) .(2)There was no statistically significant difference in the PCT level and APACHE Ⅱ score at ad‐mission between the two groups .In the later treatment process ,the PCT level and APACHE Ⅱ score in the survival group were progressively decreased ,while which in the death group were progressively inecreased (P<0 .05) .WT5HZ〗Conclusion PCT has an important clinical value in forcasting the prognosis of SAP .

Epithelial-mesenchymal transition (EMT) is an important biological process in embryonic development and tumori-genesis. In this process, epithelial tumor cells can obtain mesenchymal phenotypes and promote tumor invasion and metastasis. EMT is controlled by multiple transcription factors, signal pathways, and microRNAs. EMT and cancer stem cells are closely related. EMT also promotes the self-renewal ability of tumor cells and the overexpression of EMT-related markers in tumor cells with stemness. Some mi-croRNAs can control EMT process and stemness. In this study, recent developments on EMT and cancer stem cells in tumor metastasis were summarized to provide new insights into target therapy of tumor metastasis and recurrence.

[Objective]To evaluate the outcome of the Pemberton osteotomy for the treatment of developmental dysplasia of the hip (DDH) in older children. [Method]There were 21 children (24 hips) older than 7 years in our study , who received the Pemberton osteotomy, and combined with femoral shortening, derotational or varus osteotomies according to the level of dislocation, anteversion and neck-shalf angle of the femur. The average age at operation were 9 years and 7 months (range: 7~13.5 years).[Result]The mean follow-up were 5 years and 5 months. Eighteen hips achieved the excellent or good clinical results according to the McKay's clinical criteria. All of the hips got improvements of the Acetabular Index, Sharp Acetabular Angle, Center-Edge Angle and Acetabular Head Index. The average results were in the normal range. Eighteen hips got ⅠorⅡclass of the Severin’s radiographic classification.However, 9 hips were limited in the range of movement. Four hips got subluxation.Six hips developed avascular necrosis of the femoral head. Three hips got improved osteoarthritis.[Conclusion]The Pemberton osteotomy for the treatment of developmental dysplasia of the hip in older children can mostly achieve well-used, contained or concentric reduction hips, meanwhile need to reduce the complications.

Objective To investigate the influence of neuro-specific DNA repair gene Nbn on the development of granular cells in hippocampus of monatal mouse. Methods The hippocampus development of postnatal mouse was evaluated by comparing the morphological differences of granular cells in hippocampus between the Nbn gene knockout mice (Nbn-CNS-Del) and the controls (Nbn-CNS-Ctr). Serial sections, immunohistochemistry and stereology methods were used to quantitatively analyze the development of granular cells in hippocampus of mice on the postnatal day 7, 14 and 21 (P7d, P14d and P21d). Results In Nbn-CNS-Ctr group, the granular layer in hippocampus manifested "C" in shape, the section area of granular layer was increased, and so was the cell body of granular cells in hippocampus during P7d to P21d; the inner arm granular cells in granular layer of hippocampus emerged on P7d, and most obvious changes occurred during P7d to P14d. While in Nbn-CNS-Del group, the granular layer in "C" shape were seen to form in most of the specimens during P7d to P21d, though they were sparsely distributed. Compared with that of the mice in Nbn-CNS-Ctr group, the development of granular layer in hippocampus of the mice in Nbn-CNS-Del group lagged obviously, and the sectional area of granular cells decreased significantly (P

The corneal refractive surgery is invented and improved constantly from 1970's till now,and the excimer laser corneal refractive surgery is the important method for correcting myopia.The corneal safety of post-operation long time is the key point and always is worried by surgeon due to the surgical procedure directly on the normal corneal tissue by different types of flap and ablation. From the corneal safety of view,the advantages and disadvantages of different corneal refractive surgeries were compared and the indications for different methods were mentioned in order to provide rational clinical data.

Cushing's disease defined as hypercortisolism caused by an ACTH-secreting pituitary adenoma.Transsphenoidal surgery is currently the primary therapeutic option for Cushing's disease.The surgery aim is to resect adenoma totally,correct high cortisol status,conserve pituitary function at same time.This review is just about the recent studies about diagnosis and replacement therapy during pri-operation period of Cushing's disease.

The physical change of astigmatism in human eye is analyzed in this article.Different methods for astigmatism applied in clinic are expound and compared with advantages and disadvantages.It is important that analyzing carefully and designing customized normgram for astigmatism eye to approach the perfect visual function after reasonable treatment.

Radiation therapy (RT) plays an important role in the multimodality management of patients with breast cancer. Traditional RT techniques increase risk of death from cardiovascular diseases. With the development of new techniques, cardiac injury after RT has already been reduced. This article summarizes the studies on reducing cardiac injury by the development of RT techniques, as well as analyzes of risk factors for cardiac injury.Possible causes will also be discussed.
