OBJECTIVE: To explore the materials and selection of esophageal stents, and to discuss the application of covered stants in treating esophageal malignant stenosis.METHODS: CNKI and Medline databases were retrieved by computer for papers published from 1980 to 2009 with search terms of "esophageal carcinoma, esophageal stenosis, esophageal stent, and fabric-covered metallic stent". The language was limited for Chinese and English. A total of 61 iteratures were initial searched by computer, according to inclusive and exclusive criteria, 29 literatures were selected by the first author. Problems including esophageal stent category, material selection, as well as application of covered stents in treating esophageal malignant stenosis were reviewed and summarized.RESULTS: Totally 29 literatures were included in this paper. No concealed allocation or blinding method was described in the literatures. According to preparing materials, the stents could be divided into stainless metal stent, memory metallic stent and polyester plastic stent. As tissue-engineered materials, stents could be assigned into biodegradable polymer matrix stent and non-degradable biodegradable polymers stent. Each material stent possesses distinct advantage and disadvantage. The covered stents could relief esophageal stenosis effectively, interrupt tumor growth, and prevent restenosis. CONCLUSION: As a palliative therapy for treating esophageal malignant stenosis, covered stents can elevate patients' life quality and prolong survival times.

The side effects of cesarean with the increasing rate section began to attract the attention of pediatricians in recent years. Previous studies reported that the incidence of neonatal pnermothorax by full-term cesarean section, especially selective cesarean section, was significantly higher than vaginal birth or non-selective cesarean section. In addition, with an extensive establishment of NICUs in China and widely use of mechanical ventilation, the rate of successful neonatal rescue was improved obviously, but the incidence of pneumothorax was increasing. Studies suggested that the incidence of neonatal iatrogenic pneumothorax was highly relevant with selective cesarean section and mechanical ventilation. The indications for cesarean section and mechanical ventilation should be carefully considered.

ObjectiveTo investigate the psychological state and care measures for patients undergoing pereutaneous coronary intervention (PCI). Methods300 patients treated with PCI from December 2009 to June 2011 in our hospital were chosen as the research object.The factors arousing psychological disorders for PCI patients were taken for comparison.And then the appropriate nursing measures were discussed. ResultsThe most evident negative emotion of PCI patients was depression.The factors arousing negative emotion included the factors of family members and undesirable environment by many people going in and out. ConclusionsEffective measures can avoid the psychological barriers of PCI patients and improve the quality of postoperative recovery for patients.

Objective To investigate the women during pregnancy because of various reason caused by the impact of diabetes on perinatal outcome.Methods The delivery 24-28 weeks pregnant or first diagnosed more than 28 weeks after the gynecology clinic diagnosis with diabetes in 125 singleton pregnant women and newborns were selected as the research object of study.Except giving birth to the same period 95 cases of normal of diabetes single fetus of pregnant women and their newborn for the control group.The complications of pregnancy and gestational age,birth and neonatal intrauterine nutrition status,mode of delivery,neonatal asphyxia,hypoglycemia and jaundice,case analysis,comparison.Results The two groups in the average age,average number of pregnancy pregnancy and intrauterine nutrition(group GDM,PI =2.717,control group 2.469) and the rate of neonatal asphyxia were not statistically significant(P ＞ 0.05).GDM group of 71 cases of cesarean section,natural childbirth in 54 cases,31 cases of control group difference and 64 cases,very significant differences between the two groups (x2 =12.678,P ＜ 0.01),group GDM,the incidence of neonatal jaundice neonatal hypoglycemia respectively 18.4%,24%,and 7.4% in the control group,there was significant difference compared with 12.6% (x2 =4.500,5.577,all P ＜0.05).Conclusion Gestational diabetes is the important reason which caused by adverse perinatal outcome.

Replacement therapy of stem cells transplantation represents a potential treatment for neural retinal diseases.Despite the encouraging results in laboratory,the clinical application of cells replacement therapy is still difficult because the limitation of seed cells,immunologic rejection,oncogenicity and ethical problems,etc.Recent breakthrough in somatic reprogramming provides a promising solution overcoming these obstacles.Further researches on virus-free reprogramming will make the clinical application of stem cell replacement therapy possible.

Nutritional therapy constitutes the basis for the integrated treatment of diabetes.It is essential for diabetic dietary management to be an individualized and balanced diet pattern based on total calorie control Carbohydrates is the main dietary ingredient to affect postprandial blood glucose levels.Dietary structure,way of eating,and physical exercise all contribute to the control of postprandial blood glucose levels.

Objective To observe the clinical efficacy of percutaneous minimally invasive plate osteosynthesis(MIPPO) in treatment of senile proximal humeral fractures(SPHF).Methods The clinical data of 41 SPHF patients treated by MIPPO were analyzed retrospectively.The effect of surgery was evaluated by Neer scoring system.Results 41 patients were follow-up for 5 to 19 months (mean 11.6 months).Based on the Neer scoring criteria:the turn of excellent,good,fair or poor were 25 cases,12 cases,3 cases,1 case,the excellent rate was 90.2％.Never happened avascular necrosis of the humeral head,plate and screw fracture,nerve injury,fractures unhealed or delay healing and other negative phenomena.Conclusion The application of MIPPO in treatment of SPHF is easy to operate,little nerve damage,good fixed performance,high reliability,which is worthy of clinical application.

A comparative study was made for evaluation of peripheral blood T lymphocyte subsets in child (40 days) and adult (5-6 months)rats.There was significant difference between child and adult rats in peripheral blood T cell subsets: in the child, there were more OX-l9+(pan T cell)and W3/25+(Th/i cell) cells, and less OX-8+ (Ts/c cell)cells as compared to the adult. In W3/25+ and OX-8+ subsets, however, the fluorescence intensity of cell surface in FCM histogram presented oppositc trend in comparison with the percentage of these cells. It is assumed that the reason resulting in such change is either T cell maturation of the down regulation of T cell antigen receptors.The data described here are provided with some important information for further study in rat T cell maturation.
