HM(hibernating myocardium)is an adaptive phenome-non of myocardium against sustained ischemia,which maintains its tissue vitality through balancing energy supply and demand.It widely exists in patients suffering from coronary heart disease. HMhas its own metabolic pattern,instead of regular FAO(fatty acid β-oxidation)-based metabolism,glycolysis became main pro-cedure.Reduction of FAO,TCA (tricarboxylic cacidcycle),ETC (electron transport chain)enzyme has been observed,ROS(reac-tive oxygen species)and UCP2(uncoupling protein 2)have been up-regulated.UCP2,which promotes proton leak across innermembrane of mitochondrial and leads to ATP reduction,has e-merged as an important regulator of the energy production.It is regulated by up-stream proteins such as AMPK,PPARs,PGC-1α,and other factors like FFA(free fat acid),ROS and purine nucleotide.HM has potential function of ischemic myocardium, which can improve cardiac function through reasonable interven-tion.Modulation of UCP2 can optimize energy production,and is essential to HM metabolism.

Objective To establish a multiplex real-time PCR mothed for rapid detection of seven species of intracranial bacteria after surgery. Methods Firstly ,the Gram′s identification was deter mined. Secondly , according to the results of Gram identification ,the bacterium was typed by the specific primers and probes to deter mine the distribution of bacteria. Simul taneously ,the sensitivity and specificity of this method were verified by making intracranial infected sim ulated samples and contrasting national standard method. Results The method established could complete detention within 4 hours with a good specificity. Staphylococcus aureus,Streptococcus pneumoniae ,Escherichia coli ,Pseudomonas aeruginosa pseudomonas ,Klebsiella pneumoniae and Acinetobacter baumannii could be detected at concentrations of ≥102 CFU/mL. Enterococcus faecalis could be detected at concen-trations of≥103 CFU/mL. The lowest detection limita of this method is higher than culture method for Streptococcus pneumoniae. Conclusions Real-time Multiplex PCR method was with high sensitivity and specificity. It reduced the detection time greatly and has great value in early diagnosis of bacteria in intracranial infection. It should be of great significance for guiding clinical treatment.

OBJECTIVE:
To investigate the clinical features, therapeutic methods and therapeutic efficacy of imflammatory myofibroblastic tumor(IMT)of the nasal cavity and paranasal sinuses.
METHOD:
Clinical data of 14 cases diagnosed as IMT by pathology were retrospectively analyzed. There were 8 males and 6 females,age ranging from 18 to 77 years. 12 cases of them were treated by surgery while 2 cases received postoperative radiotherapy.
RESULT:
All cases were operated. All the patients were followed up for a period of 1 to 7 years after operation and two cases were proved low grade IMT pathologically. Eight cases survived with no recurrence until the last follow-up and 6 cases relapsed, of which 4 cases died and 2 were alive with tumor.
CONCLUSION
IMT of the nasal cavity and paranasal sinuses is very rare. The diagonosis of IMT is based on pathology and immunohistochemistry. Proper diagnosis is essential to avoid mutilating and disfiguring surgical procedures. Radical excision is still the first choice of treatment for IMT of the nasal cavity and paranasal sinuses. Chemotherapy and radiotherapy may not be helpful to prevent recurrence after operation. Due to high recurrence rate, long-term follow up is necessary after operation.

Objective:To investigate the correlation between the levels of serum secreted frizzled-related protein 5 (SFRP5), sputum CXC chemokine receptor 2(CXCR2), chemokine receptor 1 (CCR1) and airway inflammation in children with acute asthma.Methods:A total of 53 cases of acute asthma (acute group), 50 cases of asthma at remission stage (stable group) and 50 cases of healthy children (control group) in our hospital from January 2017 to January 2020 were enrolled.The expression levels of serum SFRP5, CXCR2 and CCR1, as well as pulmonary function indicators (FEV1/FVC, FEV1%), fractional exhaled nitric oxide(FeNO), and airway inflammation-related cytokines[interleukin(IL-13), vascular endothelial growth factor(VEGF)] were detected, respectively.Results:The levels of serum SFRP5 was the lowest in acute group, followed by stable group, which was the highest in control group, with statistic difference ( P<0.05). The mRNA expression levels of CXCR2 and CCR1 were the highest in acute group, followed by stable group, which were the lowest in control group, with statistic difference ( P<0.05). The predicted values of FEV1/FVC and FEV1% in acute group were significantly lower than those in stable group and control group, while FeNO in acute group was significantly higher than those in stable group and control group ( P<0.05). The predicted values of FEV1/FVC and FEV1% in stable group were significantly lower than those in control group, and FeNO was significantly higher than that in control group( P<0.05). The values of FEV1/FVC and FEV1% were the lowest in acute group, followed by stable group, which were the highest in control group ( P<0.05). The values of serum IL-13 and VEGF were the highest in acute group, followed by stable group, which were the lowest in control group, with statistic difference( P<0.05). Correlation analysis showed that the level of serum SFRP5 was positively correlated with lung function index FEV1/FVC and FEV1% to the predicted value( P<0.05), and negatively correlated with the levels of inflammatory index IL-13 and FeNO ( P<0.05). The levels of sputum CXCR2 and CCR1 were negatively correlated with lung function index FEV1/FVC and FEV1% to predicted value( P<0.05), and positively correlated with inflammatory index IL-13, VEGF and FeNO( P<0.05). Conclusion:Serum SFPR5 is decreased, and septum mRNA expression levels of CCR1 and CXCR2 are elevated in asthma children, so these three indicators could be used to predict the severity of airway inflammation in asthma children, thus providing reference for clinical diagnosis and treatment.
