As pattern recognition receptors of innate immunity,Toll-like receptors (TLRs) play an important role in the identification of pathogens,regulation of adaptive immunity and signal transduction.With more exploration of the mechanism of microbial keratitis and the acute or chronic rejection after penetrating keratoplasty,the induction and regulation of TLRs on the corneal immune response is increasingly concerned.Up to now,more and more studies of immune signal pathway of TLRs in mediating inflammatory response of bacterial keratitis,fungal keratitis,viral keratitis and graft rejection have been documented.To regulate the expression of TLRs is undoubtedly available for lightening and arresting the immuno-inflammatory response.Here,the current knowledge about TLRs,their signal transduction pathway and their regulation on corneal immunity are summarized,aiming to discuss their significant effects and the potential therapeutic targets.

Branch atheromatous disease (BAD) is a deep cerebral infarction at the entrance or the origin of perforating artery because of atherosclerosis causing lumen stenosis or occlusion. It is common in clinical practice and there is often a clinical feature of progression or fluctuation in the acute phase. Its prognosis is poor and it will bring a heavy burden to the family and society. Therefore, the early intervention for patients with BAD is very important. This article reviews the treatment of BAD.

Objective To investigate the influence of early postoperative enteral nutrition on the immunologic function and inci-sion infection in the patients with colorectal cancer .Methods 81 postoperative cases of colorectal cancer were randomly divided into the early parenteral nutrition(41 cases) ,and the early enteral nutrition(40 cases) by the random number table method .The anal ex-haust time ,ambulation time and occurrence situation of incision infection ,etc .were compared between the two groups ,and the im-munological indexes changes were also compared .Results Postoperative anal exhaust time ,bed activity time and the occurrence rate of incision infection in the early enteral nutrition group were significantly lower than those in the early parenteral nutrition group (P<0 .05);Th1/Th2 and lymphocyte count in the early enteral nutrition group were significantly higher than those in the early parenteral nutrition group(P<0 .05) .Conclusion The early postoperative enteral nutrition support in the patients with colorectal cancer can effectively improve the body's immune function and is an ideal method of nutritional support .

Objective:To investigate the dynamic changes of coagulation system following radiofrequency catheter ablation(RFCA) and effect of molecular weight heparin. Methods:Blood samples were collected at 6 different times to measure the thrombin-antithrombinⅢcomplex (TAT) and hepatocyte growth factor (HGF) in 60 RFCA candidates and 22 controls undergoing electrophysiological study (EPS).Patients were randomly divided into 2 groups.Low molecular weight heparin was given to 31 pationts (subgroup B) after RFCA,but not to the others (subgroup A). Results:①Plasma TAT exhibited a double peaked pattern in the subgroup A.The first peak occurred instantly after RFCA (42.8?15.7 ng/ml),and the second 3 days later (20.1?19.4 ng/ml).The second peak was significantly higher than that of the control group (2.7?1.5 ng/ml) and the subgroup B(4.3?5.2 ng/ml)(P
