Objective To observe the effects of intervention with Simvastatin and Aspirin on carotid artery atherosclerosis(CAA).Methods 120 patients with ischemic cerebrovascular disease and complicated CAA and blood-lipid abnormality were randomly divided into the Simvastatin group,Aspirin group,Simvastatin+ Aspirin group.Each group received corresponding therapy for 6 months.The changes of serum C-reactive protein(CRP) level,blood-lipid level,the carotid artery intimal and media thickness(IMT),the plaque areas before and after treatment and the recurrence rate of cerebrovascular event among the 3 groups were compared.Results Compared with before treatment,the levels of serum CRP were significantly decreased in the 3 groups after treatment(all P

Objective Sylvian Veins morphology analysis contributes to cortex veins protection for clear surgical fields, a better choice for operation plan evaluation. Methods 33 cases diagnosed as epilepsy, male∶female=19∶14, mean ages 18.7y (9-52). Results 4 types of Sylvian Veins spreading were observed from the procession of functional surgery: long stem pattern 49%(16/33), short stem pattern 15%(5/33), long truncks pattern 33%(11/33), and absent stem pattern 3%(1/33). Conclusion Sylvian Veins morphology analysis shows that there exist 4 main patterns, which may contribute to functional surgery about frontal operculum, temporal operculum and insular lobe or intracranial electrode placement.

Objective:To explore a method of improving the nursing service ability after total hip arthroplasty (THA) among nurses in villages and towns medical health institutions under the county medical community model and to evaluate its effects.Methods:From June 1 2018 to September 30 2019, we took Department of Orthopedics, Dazhu County People's Hospital of Dazhou of Sichuan Province, as the core, and united with county medical community built by villages and towns medical health institutions with the country in organizing the nursing theoretical knowledge and specialist service ability training after THA for 140 nurses of villages and towns medical health institutions within county medical community. Before and after training, we carried out the theoretical test and practice ability test in trainers, and implemented the consistency analysis in scores of nursing assessment scales for specialist service so as to evaluate the subjective training effect. We also compared the incidence of postoperative complications, functional recovery of hip joint as well as the satisfaction among 30 THA patients before (October 2017 to September 2018) and after (October 2018 to September 2019) training so as to explore the clinical effect.Results:Before and after training, scores of theoretical achievements of nurses of villages and towns medical health institutions were 60 (56, 62) and 82 (79, 85) respectively, and scores of practice ability were 52 (47, 62) and 86 (81, 91) respectively with statistical differences ( P<0.01) . After training, the incidence of postoperative complications was lower than that before training (6.67% vs. 26.67%) ; the postoperative satisfaction, scores of Harris Hip Score (HHS) one month and three months after surgery were higher than those before training [90.00% vs. 66.67%, (73.1±6.00) vs. (57.6±6.67) , (86.6±4.49) vs. (74.5±6.20) ]among 30 THA patients with statistical differences ( P<0.05) . Conclusions:Training with the county medical community model can improve the nursing service ability of nurses in villages and towns medical health institutions among THA patients, postoperative function of hip joint of THA patients as well as patient satisfaction.

The tumor immune microenvironment (TIME) is broadly composed of various immune cells, and its heterogeneity is characterized by both immune cells and stromal cells. During the course of tumor formation and progression and anti-tumor treatment, the composition of the TIME becomes heterogeneous. Such immunological heterogeneity is not only present between populations but also exists on temporal and spatial scales. Owing to the existence of TIME, clinical outcomes can differ when a similar treatment strategy is provided to patients. Therefore, a comprehensive assessment of TIME heterogeneity is essential for developing precise and effective therapies. Facilitated by advanced technologies, it is possible to understand the complexity and diversity of the TIME and its influence on therapy responses. In this review, we discuss the potential reasons for TIME heterogeneity and the current approaches used to explore it. We also summarize clinical intervention strategies based on associated mechanisms or targets to control immunological heterogeneity.
