Microorganisms can affect the development of body immune system.Intestinal flora regulate immune function by promoting the intestinal immune system development,inducing T cell differentiation to avoid or reduce the incidence of immune-related diseases.Allergic diseases are related with the body's immune system hypoplasia and imperfect immune regulation mechanism.The immune system can be affected by intestinal flora,and the distribution of flora in the body between children with allergies and healthy children are significantly different,indicating that the occurrence of allergic diseases are associated with intestinal microflora.Studies have reported probiotic are helpful to the prevention and treatment of allergic disease,providing a new way for the prevention and treatment of allergic diseases.

Based on clinical features of refractory diseases and clinical practice experience for many years,the author expounded the therapeutic strategies from establishing individualized system of differentiation treatment,treatment strategies of refractory diseases,and the key for medication,and emphasized individual concerned therapy,separating primary and secondary treatment and grasping the physiological state to treat pathological changes.Thus complicated and changeable diseases can be treated clinically.

Cellular functions like proliferation,differentiation,migration,morphogenesis and apoptosis are modulated by the extracellular matrix.Integrins are the prototypic heterodimeric transmembrane matrix receptors with competing affinities for individual extracellular matrix ligands.The intracellular integrin domain clusters cytoplasmic proteins into focal adhesion plaques for bidirectional(outside-in and inside-out) signaling.Integrin-linked kinase(ILK) is an intracellular serine/threonine protein kinase that interacts with the cytoplasmic domains of ?-integrins.ILK organizes the connections of the extracellular matrix via integrins to the cytoskeleton and is involved in adhesion plaque signaling,and it plays a crucial role in the pathogenesis of chronic renal fibrosis.High glucose induces the upregulation of the synthesis and activity of ILK in cultivated mouse podocytes and mesangial cells.The ILK protein level is significantly increased in diabetic glomeruli.ILK activity is likely to provide the basis for an effective therapeutic method for diabetic nephropathy.This review gives an introduction of ILK structure and function,followed by a summary of our current understanding of ILK in diabetic nephropathy with a special focus on glomerular cell-matrix interaction.

A magnitude of 8.0 earthquake struck on Wenchuan on May 12, 2008. Until July 1, 1393 injured persons had been admitted to Deyang People's Hospital. Of all injured persons, 32 were diagnosed with abdominal injury, including 18 men and 14 women. All the abdominal injuries were closed injury, and multiple abdominal viscera were involved in the abdominal injuries after the earthquake. Careful examination is crucial in preventing missed diagnosis. The incidences of the liver and spleen injuries were significantly higher than that of the intestine, and the reason may be that the liver and spleen are the parenchymal viscera. Diagnostic abdominocentesis can timely diagnose the parenchymal viscera with severe blood loss. Diagnostic peritoneal lavage combined with selective CT scan can timely diagnose the abdominal injuries with comparatively low cost.

1he increased peripheral benzodiazepine receptors are more significant than normal ones after cerebral ischemia. Its main reactions are the multiple pathological changes,including microglial activation, participating in neuroinflammation response, and regulation of mitochondrial function. Using radionuclide-laheled specific ligands of the peripheral benzodiaz-epine receptor (such as PK11195) for in vivo imaging contribute to the location and quantitative detection for brain injury and the study of the pathophysiological changes after cerebral ischemi-a. In addition, this receptor is promising to become a new target of neuroprotective treatment.This article reviews the recent progress in research on peripheral benzodiazepine receptors and cerebral ischemia.

Objective To study the relationship between operative procedures and complication of colorectal carcinoma with acute colonic obstruction in the elderly patients. Methods 65 elderly patients undergoing emergency operation for acute colonic obstruction were analyzed retrospectively. One stage tumor resection and anastomosis was performed in 25 cases with right-side colonic lesion and in 26 cases with left-side colonic lesion, Hartmann operation in 8 cases, Dixon operation in 4 cases and proximal colostomy in 2 cases. Results In 65 cases, 13 cases of postopera-tive complications,the rate was 20.0% (13/65) ,which infected with toxic shock two cases,four cases of pulmonary infection,anastomotic leakage two cases, wound infection, split 2 cases, death three cases, the mortality rate was 4.6%. The rates of postoperative complications in right-side colonic lesion, left-side colonic lesion, Hartmann opera-tion and Dixon operation were 69.2% ,0,30.7% and 0 respectively(P < 0.05 ～ 0.01). Conclusion Acute obstruc-tion of colon cancer,the right-side colonic lesion were safe,feasible and few complications in colorectal carcinoma with acute colonic obstruction.

Objective To compare two types of digestive reconstruction and postoperative complications after total gastrectomy in patients with gastric carcinoma. Methods Roux-en-Y esophagojejunostomy and P-type Roux-en-Y esophagojejunostomy were performed in 50 patients with gastric carcinoma after total gastrectomy. The operating time and postoperative complications were observed. Results The gastrointestinal symptoms for Roux-en-Y esophagojeju-nostomy and P-type Roux-en-Y esophagojejunostomy serve as : diarrhea ( 11.8% and 12.1% ), dumping syndrome (3.9% and 3.3% ) and reflux esophagitis(5.9% and 6.0% ) ,the incidence of the difference was not significant ( than,P>0.05 ). The postoperative complications in P-type Roux-en-Y esophagojejunostomy( 13.1% ) slightly higher that Roux-en-Y esophagojejunostomy( 11.1% ) ,but the difference was not significant( P>0.05 ). Roux-en-Y esoph-agojejunostomy average operative time(3.1±0.3)h was significantly reduced than P-type Roux-en-Y esophagojeju-nostomy(3.7±0.2)h(t=3.35,P<0.05). Conclusion Roux-en-Y esephagojejunostomy and P-type Roux-en-Y esophagojejunostomy is a suitable type after total gastrectomy for patients with gastric carcinoma, but the former opera-tive time was shorter.

[ ABSTRACT] AIM:To explore the effects of transcription factor HOXB7 silencing on the viability , invasion and migration of SGC-7901 cells.METHODS:The siRNA was designed to specifically interfere the expression of HOXB7.To assess the silence efficiency of the siRNA , the expression of HOXB7 at mRNA and protein levels was detected by real-time PCR and Western blot in the SGC-7901 cells transfected with siRNA .The cell viability was measured by MTT assay .Cell cycle-related proteins such as cyclin D 1 and CDK4 were determined by Western blot .Transwell assay was performed to an-alyze the migration ability of the SGC-7901 cells.The mRNA and protein levels of the tumor invasion-and metastasis-relat-ed molecules, such as VEGF, PTEN and p-AKT, were also detected by real-time PCR and Western blot .RESULTS:The expression of HOXB7 at mRNA and protein levels was higher in the gastric carcinoma tissues than that in the normal gastric tissues.The expression of HOXB7 at mRNA and protein levels was knockdown by siRNA .After silencing of HOXB7 gene expression, the viability of the SGC-7901 cells decreased, the expression of cyclin D1, CDK4 and VEGF was down-regula-ted, and the phosphorylation level of AKT was also obviously decreased .CONCLUSION:HOXB7 effectively promotes the viability, invasion and migration of gastric carcinoma cells by up-regulating the expression of cyclinD 1, CDK4 and VEGF, and increasing the phosphorylation level of AKT to inhibit PTEN function .
