Objective:To explore the effect of applying the multi-disciplinary team（MDT）model led by specialized nursing care in the treatment carried out at early stage in intensive care unit of hyperbaric oxygen（ICU-HBO）for patients with brain complications after Stanford type A aortic dissection（AD）surgery.Method:From January 2018 to December 2020，a total of 18 patients with brain complications after AD surgery were included and treated by ICU-HBO with MDT model. The patients’ ventilator tolerance and weaning time，outcome，occurrence of adverse events，and satisfaction rate of nursing care were observed.Results:（1）Fifteen mechanically ventilated patients were successfully weaned off the machine after 1-5 times of ICU-HBO treatment.（2）Sixteen patients regained their consciousness to the normal level after 2-13 times of ICU-HBO treatments，with the total effective rate of 88.89%；two patients in persistent vegetative state（deep coma）discontinued the treatment after two times of ICU-HBO treatments as their family gave up. During the follow-up period of six months to two years，11 cases were found clinically cured，one case was considered effective，four cases lost contact，and the two cases that had gave up treatment died of complications.（3）No adverse medical event（related to safety）occurred during the ICU-HBO treatment.（4）The satisfaction rate of nursing care was 100%.Conclusion:In the early ICU-HBO treatment of patients with brain complications after Stanford type A AD surgery，the application of MDT mode led by specialized nursing care is beneficial to the treatment risk control，ensure the treatment effectiveness，and improve the long-term prognosis，and quality of life of AD patients.

Objective To evaluate the efficacy of the new treatment regimen versus the standardized scheme for the initial treatment of smear-positive tuberculosis in the elderly.Methods A total of 302 elderly patients meeting the inclusion and exclusion criteria were selected from 14 tuberculosis-designated medical institutions in Beijing.The patients received the initial treatment of smear-positive tuberculosis from January 2014 to August 2016 in the combined prospective and retrospective study.All patients were divided into observation group(n=63)receiving treatment with 6L2 HELfx regimen from August 1,2015 to August 31,2016,and control group (n =239) receiving treatment with 6L2HELfx regimen from January 1,2014 to January 31,2015.The nation-unified standard chemotherapy regimen 2RHZE/4RH was used in tuberculosis medical service institutions for all patients.The differences between the two groups were analyzed and compared in the completion of treatment,negative conversion of sputum culture or smear,adverse drug reactions and treatment outcome.Results The completion rate of long-course therapy was significantly higher in the observation group than in control group [90.5％ (57/63) vs.79.5％ (190/239),x2 =4.034,P =0.045].The rate of negative conversion of sputum culture or smear at the end of the 2nd month was higher in the observation group than in control group,but had no significant difference[87.0％ (47/54)vs.81.6％(155/190),x2 =0.879,P=0.349].The incidence of adverse reactions was much lower in observation group than in control group[46.0％ (29/63) vs.65.3％ (156/239),x2 =7.777,P =0.005].The success rate of treatment(cure or completion of long-course therapy)was higher in observation group than in control group [90.5％ (57/63) vs.77.4％ (185/239),x2 =5.350,P =0.021].ConclusioNS As compared with the standard chemotherapy regimen,the L and Lfxcontaining treatment regimen has better effects,higher success rate of treatment and less adverse reactions in elderly patients with the initial treatment of smear-positive tuberculosis.

AIM: In order to investigate the change of CD36 expression in atherosclerosis. METHODS: Chinese minipigs were fed a normal control diet (CD) or a high fat/high cholesterol diet (HFHC) for 12 months after common carotid artery injury induced by balloon denudation. Plasma total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) were determined by commercially enzymatic methods. CD36 mRNA and protein levels were determined by reverse transcriptase-polymerase chain reaction (RT-PCR), Western blotting and immunohistochemistry, respectively. RESULTS: After HFHC for 12 months, plasma total cholesterol, HDL cholesterol and triglyceride in HFHC minipigs were increased compared with the control. CD36 expression and aorta PPAR? in HFHC minipigs were upregulated. CONCLUSION: HFHC may induce hyper cholesterolemia, hypertriglyceridemia and upregulation of CD36 and aortic PPAR? expression.
