Objective To compare the hemodynamic responses to orotracheal intubation during emergency operation with the proseal laryngeal mask airway and endotracheal Intubation.Methods Fifty six patients who were ASA GRADE Ⅰ-Ⅱ before onset undergoing orotracheal intubation were randomly dirideed into either without laryngoscope direct proseal laryngeal mask intubation(PLMA) group or direct laryngoscope endotracheal intubation(TT) group.SBP、DBP、HR and SpO2 were recorded before,durring and 5 minutes after intubation.Intubation time and first attempt insertion success rate were recordeddso.All patients were followed up postoperatively for adverse effects like sore throat or hoarseness.Results In intubation time、first attempt insertion success rate and adverse effects like sore throat or hoarseness,PLMA group was 96.43%,(19.7?5.7)s and 7.1%,TT group was 100%,(27.9?11.3)s and 39.29%.Intubation time was significantly shorter and adverse effects like sore throat or hoarseness were lower in the PLMA group than TT group(P

Sepsis is an infection induced systemic inflammatory response syndrome and is a major cause of morbidity as well as mortality in intensive care units. A growing body of evidence suggests that the activation of a proinflammatory cascade is responsible for the development of immune dysfunction, susceptibility to severe sepsis and septic shock. The present theories of sepsis as a dysregulated inflammatory response and immune function, as manifested by excessive release of inflammatory mediators such as high mobility group box 1 protein (HMGB1), are supported by increasing studies employing animal models and clinical observations of sepsis. HMGB1, originally described as a DNA-binding protein and released passively by necrotic cells and actively by macrophages/monocytes, has been discovered to be one of essential cytokines that mediates the response to infection, injury and inflammation. A growing number of studies still focus on the inflammation-regulatory function and its contribution to infectious and inflammatory disorders, recent data suggest that HMGB1 formation can also markedly influence the host cell-mediated immunity, including T lymphocytes and macrophages. Here we review emerging evidence that support extracellular HMGB1 as a late mediator of septic complications, and discuss the therapeutic potential of several HMGB1-targeting agents in experimental sepsis. In addition, with the development of traditional Chinese medicine in recent years, it has been proven that traditional Chinese herbal materials and their extracts have remarkable effective in treating severe sepsis. In this review, we therefore provide some new concepts of HMGB1-targeted Chinese herbal therapies in sepsis.

Ultrasonography examinations were performed for carotid atherosclerosis in 548 patients with type 2 diabetes mellitus (T2DM). Blood glucose, glycosylated hemoglobin, total serum bilirubin, uric acid, total cholesterol ( TC ), triglycerides ( TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL) were measured. Total serum bilirubin level in T2DM patients without carotid atherosclerosis was (13.0±7. 1 )μmol/L, while that was (10. 9 ± 4. 9 )μmol/L in patients with carotid atherosclerosis (P ＜0. 01 ). The logistic analysis showed that total serum bilirubin level was negatively related to the presence of carotid atherosclerosis ( P ＜ 0. 05 ), which indicated that higher level of total serum bilirubin might be a protective factor for macroangiopathy in T2DM.

OBJECTIVE: To observe the expression of discs large homolog 4 (DLG4) protein in hippocampus, amygdala and frontal cortex of rats and evaluate postsynaptic density in heroin dependence. METHODS: The rat heroin dependent model was established by increasing intraperitoneal injection of heroin. DLG4 proteins in hippocampus, amygdala and frontal cortex of heroin dependent 9, 18, 36 days rats were detected with immunohistochemical staining and compared with that in the control group. RESULTS: DLG4 proteins in hippocampus, amygdala and frontal cortex were gradually reduced with extension of heroin dependent time. CONCLUSION Heroin dependence can affect postsynaptic density of hippocampus, amygdala and frontal cortex. The changes become more apparent with extension of heroin dependence time.

Metastatic epidural compression of the spinal cord is a significant source of morbidity in patients with systemic cancer. With improvment of oncotheray, survival period in the patients is improving and metastatic cord compression is en- countered increasingly often. Surgical management performed for early circumferential decompression for the spinal cord com- pression with spine instability, and spine reconstruction performed. Patients with radiosensitive tumours without spine instabili- ty, radiotherapy is an effective therapy. Spinal stereotactic radiosurgery and minimally invasive techniques, such as vertebro- plasty and kyphoplasty, percutaneous pedicle screw fixation, radiofrequency ablation are promising options for treatment of cer- tain selected patients with spinal metastases.
