Objective To study the effects of TGFβ-activated kinase-1 (TAK1)mediated cell autophagy after global cerebral ischemia-reperfusion (IR ) in rats.Methods Seventy-two male Kunming rats were randomly divided into six groups:control group (group C),sham operation group (group S),ischemia-reperfusion group (group IR),TAK1 shRNA lentivirus group (group T),nega-tive lentivirus group (group Y)and normal saline group (group NS)(n = 12 each).The rats in groups T,Y and NS received cerebral ventricles injection of TAK1 shRNA lentivirus,negative lenti-virus and normal saline 10 μl two weeks before preparing animal model.Using thread embolism of the right middle cerebral artery occlusion (MCAO)to cause focal ischemia for 2 h and released for 24 h for reperfusion in groups IR,T,Y and NS.The common carotid arteries were separated but not liga-ted in group S,the rest of the procedure as the same as group IR.The rats of each group were evalua-ted by neurological severity scores (NSS)24 h after reperfusion,the cerebral infarct volume was measured with the method of TTC and the expression of TAK1,LC3Ⅱ/LC3Ⅰ,Beclin1 and p62 pro-tein in rat hippocampus were determined by using Western blot.Results The infarct volume and NSS in groups IR,T,Y and NS were significantly higher than those in group C (P <0.05).The infarct volume and NSS in group T were significantly lower than those in group IR (P <0.05).TAK1 pro-tein of hippocampus in groups IR,Y and NS was significantly higher than that in group C (P <0.05).TAK1 protein of hippocampus in group T were significantly lower than that in group IR (P <0.05).LC3Ⅱ/LC3 Ⅰand Beclin1 protein of hippocampus in groups IR,T,Y and NS were signifi-cantly higher than those in group C,and the p62 protein of hippocampus in groups IR,T,Y and NS was significantly lower than that in group C (P <0.05).The LC3 Ⅱ/LC3 Ⅰand Beclin1 in group T were significantly lower than those in group IR,and the p62 protein of hippocampus in group T was significantly higher than that in group C (P < 0.05 ).Conclusion TAK1 mediated cell autophagy takes part in the mechanism of brain ischemia-reperfusion injury in rats.

Objective To evaluate the clinical features of osteoarticular damage of patients with brucellosis,and to enhance the knowledge of clinical doctors.Methods The demographic characteristics,clinical presentations,accessory examination of 265 patients with brucellosis admitted from January 2011 to April 2014 in Ji'nan Infectious Diseases Hospital were retrospectively analyzed.Patients were classified into two groups:Patients with osteoarticular complications and patients without osteoarticular complications.Results Of the 265 patients,forty-six patients (17.36％) had osteoarticular complications.Spondylitis was the most common complication [50.00％ (23/46)],followed by sacroiliitis [41.30％ (19/46)] and peripheral arthritis [26.09％ (12/46)].Sacroiliitis was more common than other types of osteoarticular damage in females [21.74％ (10/46)],whereas in males spondylitis was more common [36.96％ (17/46)].Peripheral arthritis was more common in individuals under the age of 17 years old [4.35％ (2/46)],and sacroiliitis were more common in the ages of 18-60 years old group [23.91％(11/46)] and spondylitis were more common in over 60-year age group [30.43％ (14/46)].Patients with osteoarticular complications showed longer duration of illness from the onset of the symptoms to its diagnosis (median 45 days),compared to those non-osteoarticular brucellosis (median 30 days,Z =5.74,P ＜ 0.05).Conclusion Due to diversity of osteoarticular damage in patients with brucellosis,in case of a patient with long-term fever and osteoarticular symptoms,medical and epidemiological history should be inquired so as to strengthen early diagnosis and treatment of the disease based on combination with radiological findings.

Objective To compare the bispectral index score ( BIS) correlationbetween standard frontal sensor position and an alternative zygomatic position under general anesthesia with propofol combined with remifentanil during neurosurgery. Methods Twenty patients undergoing neurosurgery were enrolled. Everyone received total intravenous anesthesia by target-controlled infusion of propofol and remifentanil. Two BISTM Quatro sensors mounted on the frontal and zygomatic regions were connected to BIS VistaTM monitors on each patient during general anesthesia.Data from each position were collected and analyzed at the time of awakening ( t1 ) , intubation ( t2 ) , incision ( t3 ) , the end of surgery ( t4 ) , and extubation ( t5 ) . Results At t1 , zygomatic BIS(88.95±6.42) was significantly lower than frontal BIS (84.85±9.64,P<0.01).But during anesthesia,different of BIS value was no statistical significance between the standard frontal position and an alternative zygomatic position(P>0.05). Scatter plot analysis revealed a significant correlation between BIS of frontal positionand that of zygomatic position( R2=0.892,P=0.000) . Conclusion During the anesthesia maintenance period,the zygomatic position can be availably used as an alternative position for monitoring if the operative field renders the standard frontal position unavailable.
