DNA, as the material basis of all living cells, triggers innate immune responses through TLR9 and other cytosolic recognition receptors. In recent years, the research progress of TLR9 is mainly manifested by the following four aspects: (1) the determinants of TLR9 interacting with its ligands; (2) the mechanisms and the importance of TLR9 translocation from the endoplasmic reticulum to the endosome; (3) the roles of the endosomal acidification and maturation, and subsequent TLR9 cleavage in TLR9 signal transduction pathway; and (4) the possible mechanisms by which the organism distinguish self DNA from microbial DNA. Meanwhile, a series of experiments on TLR9 antagonists and TLR9 deficient mice confirmed the presence of TLR9-independent cytosolic DNA sensors. So far, three TLR9-independent DNA sensors have been found, and they are DAI, AIM2, and RNA polymerase Ⅲ.

Objective To evaluate the perioperative nutritional risk of patients with colorectal cancer. Methods Totally, the nutritional risk of 144 colorectal cancer patients who were newly admitted to our hospital and were radiotherapy-naive or chemotherapy-naive were evaluated using Nutritonal Risk Screening 2002 (NRS2002 ) before operation and two weeks after operation. Meanwhile, hemoglobin, serum levels of albumin and prealbumin, total lymphocyte count were measured and the postoperative complications were observed. Results The incidence of preoperative nutritional risk was 22. 91% (33/144). The predicted incidence of postoperative nutritional risk was 43. 06% (62/144), while the actual incidence was 54. 86% (79/144) (x2 =4. 016, P < 0.05). About 10. 13% of patients whose preoperative nutritional risk score≥3 experienced complications, while only 1. 54% of patients whose preoperative nutritional risk score < 3 had complications (x2 = 3. 065, P < 0.05). Conclusions The perioperative (especially postoperative) nutrition risk is high in patients with colorectal cancer. Patients with higher nutrition risk tend to experience postoperative complications.

Ischemic stroke is one of the diseases with the highest morbidity and disability.Hypertension is recognized as the most important independent risk factor for ischemic stroke.Vascular remodeling during the development of hypertension is the pathological basis of causing ischemic stroke.Studies have shown that vascular smooth muscle cell proliferation and apoptosis will lead to vascular remodeling.In addition,cerebral ischemia-reperfusion can result in neuronal damage and apoptosis.Recent research has shown that vascular remodeling and neuronal apoptosis are associated with chloride channels.At least 3 chloride channels including volume regulated chloride channel,calcium activated chloride channel and cystic fibrosis transmembrane conductance regulator are involved in these processes.This article reviews the roles of the 3 chloride channels in vascular remodeling,neuronal apoptosis,and ischemic stroke.

Objective To observe the THP for locally advanced breast cancer in recent efficacy and toxicity. Methods 32 patients with locally advanced breast cancer received chemotherapy: THP 50mg/m~2 , intravenous injection; day 1: CTX600mg/m 5 - FU500mg/m~2, ivgtt on day 1 and day 8,for a period of 21 days. Results 73% had efficiency,with small heart poisonous side effects. Conclusion New adjuvant chemotherapy with THP - containing regimen for the treatment of locally advanced breast cancer has a higher efficacy, and adverse reactions can be tolerated.

By analyzing the role of shared equipment in the share center of medical equipment, key factors in managing the share center are pointed out. According to the practice and experience in hospital, measures of giving full play to shared equipment are discussed from many aspects which include proper keeping, moderate collocating, concrete exchanging, popular training, timely repairing and precise checking, etc.

Pharmacogenomics refers to all the genes encoding drug-metabolizing enzymes,drug transporters,and other drug targets. Studying the relations betweeen gene polymorphisms and drug effects as well as the prediction of adverse reactions at the gene level will be a new method for the clinical therapy of digestive system diseases. Therefore,pharmacogenomics will be a complement of traditional methods for forming and administering drugs regimens.

Nitric oxide (NO) played an important role in the pathogenesis of many diseases. It selectively dilates the pulmonary vasculare, combats pulmonary hypertension associated with hypoxemia, improves oxygen. At the same time, it could relaxe bronchial smooth muscle, kill pathogens and have anti-inflammatory effect,etc. Inhaled nitric oxide has important significance in the treatment of respiratory diseases.

Objective To investigate the correlations between plasma indoxyl sulfate and p-cresyl sulfate in the pathogenesis of cardiovascular complications in maintenance hemodialysispatients.Methods A total of 145 maintenance hemodialysis patients were selected.The researchers measured the physiological parameters of the subjects,including pre albumin,albumin,hemoglobin,blood urea nitrogen,creatinine,uric acid,calcium,phosphorus,alkaline phosphatase,total cholesterol,triglyceride,low-density lipoprotein cholesterol,high-density fat cholesterol,intact parathyroid hormone,C-reactive protein,apolipoprotein,lipoprotein,homocysteine,beta 2-microglobulin,sulfuric acid indoxyl,sulfuric acid cresol,serum iron,transferrin,ferritin,and N-terminal pro brain natriuretic peptide carrier.Subjects underwent cardiac ultrasound examination.Results The researchers used heart structure and function as the dependent variable.The single factor Cox regression analysis showed that the risk of heart structure and function changes increased with the increase of systolic blood pressure,N-terminal B-type natriuretic peptide,and left ventricular mass index.This study also showed that the risk of heart structure and function changes in patients with previous history of coronary heart disease also increased.The researchers took the systolic blood pressure,coronary heart disease history,N-terminal brain natriuretic peptide,and the left ventricular mass index as the dependent variables.Multifactor Cox regression analysis showed that the history of coronary heart disease,the high left ventricular mass index and the change of the heart structure and function of the patients with acute coronary heart disease were the independent predictors of the change of heart structure and function.The researchers used cardiovascular complications as the dependent variable.Cox regression analysis showed that,with the increase in patient's age,dialysis duration,elevated high C-reactive protein and sulfuric acid p-cresol,patients suffering from the risk of fatal cardiovascular complications rise.The researchers used the complications of cardiovascular deaths as dependent variable,age,duration of dialysis,C-reactive protein,and sulfuric acid p-cresol as covariates,multivariate Cox regression analysis of the results showed that with increasing age,dialysis duration increased,high sulfate of cresol and C-reactive protein,patients suffering from the risk of death from cardiovascular complications rise.Conclusions The history of coronary heart disease,left ventricular mass index,systolic blood pressure,indoxyl sulfate,Nterminal brain natriuretic peptide,age,dialysis age,high C-reaction protein,and p-cresol sulfate are the independent risk factors for cardiovascular complications.The relationship between indoxyl sulfate and sulfuric acid serum concentration of p-cresol and adverse cardiovascular events is most closely.

High mobility group protein box 1 (HMGB1) is a typical nonhistone chromosomal protein. It has many celular functions in nucleus. Studies in recent years have showed that HMGB1 can be released to the outside of cels to exert a wide range of cytological effects. Ischemic stroke is one of the diseases with the highest morbidity and disability. More and more evidence has shown that HMGB1 plays a variety of important roles in the occurrence and development process of ischemic stroke. This article reviews the roles of HMGB1 in ischemic stroke.
