Objective To investigate the effect of sevoflurane preconditioning on the expression of Toll-like receptor 4(TLR4) during myocardial ischemia reperfusion(IR) in rats.Methods Thirty male SD rats weighing 250-300 g were randomly divided into 3 groups (n=10 each):sham operation group (S group) , IR group and sevoflurane preconditioning group(SP group).Myocardial ischemia was produced by temporary ligation of anterior descending branch of left coronary artery for 30 min followed by 2 h reperfusion. In SP group, the animals inhaled 2.5% sevoflurane for 30 min followed by 15 min washout before ischemia. The rats were sacrificed at 2 h of reperfusion, hearts removed and myocardial tissues obtained for microscopic examination.The expression of TLR4, NF-κB and TNF-α was detected using Western blot. Results The expression of TLR4, NF-κB and TNF-α was significantly up-regulated in IR and SP groups compared with group S (P＜0.05).The expression of TLR4, NF-κB and TNF-α was significantly down-regulated in group SP compared with group IR (P＜0.05).The myocardial injury was attenuated in group SP.Conclusion Sevoflurane preconditioning can attenuate myocardial IR injury by inhibiting the up-regulation of TLR4 expression and reducing the inflammatory response.

Objective To evaluate the value of revised Geneva score, Daniel ECG score and age-adjusted D-dimer for predicting pulmonary embolism(PE).Methods A total of 91 cases suspected as pulmonary embolism were collected, and 52 cases were diagnosed as pulmonary embolism by computed tomographic pulmonary angiography(CTPA) results.Receiver operating characteristic(ROC) curves and diagnostic test evaluation indexes were used to evaluate the probability of PE predicted by the revised Geneva score,Daniel ECG score, age-adjusted D-dimer and combination of these two clinical scores and age-adjusted D-dimer.Results The confirmed PE was 21.4% with a low probability(revised Geneva score 0~3 points),55.4% in intermediate probability(4~10 points),85.7% in high probability(score≥11 points).The prevalence of PE was 33.3% with a low clinical probability (Daniel ECG score<2 points)and 70.7% with a high clinical probability(Daniel ECG score≥2 points).The sensitivity and specificity of age-adjusted D-dimer in predicting pulmonary embolism were 92.3%,69.2%.The area under curve of the ROC curve(AUC)in the revised Geneva score and Daniel ECG score has no significant difference(Z=0.979).The negative predictive value of the revised Geneva score, Daniel ECG score combined with D-dimer in pulmonary embolism were 100.0% and 87.5%.Conclusion All of revised Geneva score, Daniel ECG score and age-adjusted D-dimer have certain predictive value on pulmonary embolism , and the revised Geneva score combined with age-adjusted D-dimer can be more safely exclude pulmonary embolism.

Objective To explore clinical characteristics and treatment of the thrombotic microangiopathy (TMA) induced by malignant hypertension, and provide a better understanding of the disease. Methods The clinical manifestations, laboratory examinations, therapeutic methods and prognosis of 15 TMA patients induced by malignant hypertension were analyzed retrospectively. Results The clinical manifestations were characterized by microangiopathic hemolytic anemia, thrombocytopenia and kidney injury. None of the patients required plasma exchange therapy. After antihypertensive treatment, all of 15 patients were discharged with improved clinical condition, remoglobin levels and platelet count. Conclusions The TMA induced by malignant hypertension is different from the classic TMA. Improving the understanding of TMA induced by malignant hypertension will contribute to early diagnosis and targeted treatment.

In the last decade, next-generation sequencing (NGS) technology, which is characterized by being high-throughput, rapid, sensitive, and accurate, has developed rapidly. Main components of NGS are platforms: 454 sequencing; illumina sequencing; ion torrent sequencing; SOLID sequencing. NGS is used widely for the human immunodeficiency virus (HIV)-1. In this review, we focus on applications of the dynamics of HIV-1 quasispecies.

The effectiveness and efficiency of university educational management would have a direct impact on universities' teaching performance.Moreover,it is important to undertake a further reformation for the educational management system of university and college and establish such a standardized,high efficient educational management system.Since they would be the milestones that improve universities'teaching performance constantly and ensure there is a persistent evolution in universities as well.

Neoadjuvant chemotherapy is one of the common means in multidisciplinary treatment of locally advanced breast cancer,with anthracyclines and taxanes as main chemotherapeutic drugs.In recent years,molecular target agents have significantly improved the efficacy of chemotherapy,as well as have provided more choices and ideas for clinical treatment.Currently,the widely studied molecular targeted drugs include trastuzumab,lapatinib,pertuzumab,T-DM1 and bevacizumab.

Objective To investigate the relationship of self-management skills and the quality of life among solitary elderly patients with hypertension.Methods 110 cases of solitary elderly patients with hypertension were measured with self-designed Self-management of Hypertension Scale and Short Form Health Survey (SF-36) and the correlation of them was analyzed.Results The levels of self-management skills of elderly hypertensive patients was at a middle level,and the mean score of self-management skills was (78.6 ± 5.2) points.The total score of SF-36 of patients with good self-management skills was higher than those with bad self-management skills.The therapy management,catering management,psychosocial management,sports management and overall quality of self-management of elderly patients with hypertension were positively correlated with survival quality.The factors influencing self-management ability of patients incuded education,gender,social resource utilization,psychological conditions.Conclusions Community health nurses should pay attention to self-management skills such as diet,exercise,therapy,social and psychological aspects in elderly hypertensive patients in order to improve their quality of life.Furthermore community nurses should strengthen intervention for solitary eldedy males with lower education level,poor utilization of social resources to improve their self-management skills.
