Aim To explore the role of nicotinamide adenine dinucleotide phosphate ( NADPH ) oxidase in high glucose-induced injury in H9c2 cardiac cells. Methods H9 c2 cardiac cells were exposed to differ-ent concentrations of high glucose(5. 5 mmol·L-1 ,11 mmol · L-1 ,22 mmol · L-1 ,33 mmol · L-1 ,44 mmol ·L-1 , 55 mmol · L-1 ) for 24 h and different time pints of high glucose(0 h,12 h,24 h,36 h,48 h,72 h) . Cell viability was measured by MTT colorimetry, the protein expression of Bcl-2 , Bax and NADPH oxi-dase submits such as p22 phox , p47 phox and p67 phox were determined by western blotting. Results H9c2 cardi-ac cells exposure to high glucose for 24 h showed on decrease in cell survival and the Bcl-2 expression while an increase in the Bax expression ( P<0. 05 ) . Moreo-ver, high glucose could markedly up-regulate the activ-ity of NADPH oxidase characterized by the enhanced expression of p22 phox , p47 phox and p67 phox ( P<0. 05 ) . Conclusion Activating NADPH oxidase may play an important role in high glucose-induced injury in H9 c2 cells.

All of the thrombolytic agents currently approved for use in humans are plasminogen activators, the application of which is limited by bleeding complications at vascular injury sites and plasminogen content in the thrombus. Plasmin is rapidly neutral-ized in the circulation by α2-antiplasmin and tolerated without bleeding. With the application of catheter-based delivery, the unique bio-chemical properties of plasmin make it a safe and effective direct fibrinolytics. Plasmin derivatives, including miniplasmin,Δ-plasmin and microplsmin, display more thrombolysis efficacy and better hemostatic safety in preclinical study and clinical trials. This review sum-marizes the current information on plasmin and its derivatives, including the advances on biochemical properties, preclinical and clinical trials.

Immune system is a security guard to help human body repel or remove bacteria, viruses, parasites and other fore-ign invaders .But when some tissue components or the immune system itself become abnormal, it can not distinguish friend from foe accurately and may attack our own tissue then cause some clinical symptoms, leading to autoimmune diseases. Nearly 5 % of the world's population suffer from various autoimmune diseases. By now in addition to control the formation of autoantigens such as infection,tiredness, the main biologics used in clinic are immunoregulators to block pathological autoimmune response and then to create a new proper immune response. Recently, new biologics to treat autoimmune disease come into being one after another, and this article gives a brief overview about research progress in anti-autoimmune disease biologics.

Objective To explore the pre-requisite "highlight" of information system in a new outpatient building and its significance on outpatient information construction.Methods The importance of new outpatient information system for improving the treatment of the environment and optimizing the outpatient treatment processes were analyzed from information dissemination system,self-service system and intelligent queuing system.Results The systemic design plan and actual role of the three systems were given by combining actual situation of the new outpatient building construction.Conclusion Having greatly improving for the outpatient information construction and the new outpatient building will have a positive impact on hospital management model,medical model and informationation construction.

OBJECTIVE: To investigate the clinical feature,diagnostic and therapeutic methods of ultimobranchial fistula and cyst of thyroid. METHOD: Four cases of ultimobranchial fistula and cyst of thyroid in our hospital were reported and the relevant literatures were reviewed. RESULT: The branchial fistula and cyst of four cases were adhered to thyroid,with unclear anatomical landmarks, the function of recurrent laryngeal nerve were bad before the operation in two cases. The nerve of four cases were retained, the function of thyriod and parathyroid gland were normal and no recurrence were found. CONCLUSION Ultimobranchial fistula and cyst of thyroid is rare and is easier to be misdiagnosed and wrong treated. Surgical excision is effective for it and recurrent laryngeal nerve should be protected when performing the operation.

Objective To investigate the effect of different parts leukoencephalopathy on cognitive function in patients with acute cerebral infarction,and analyze the relationship between injury site of cholinergic pathways and cognitive function.Methods Ninety-seven patients with acute cerebral infarction were divided into leukoencephalopathy group (59 cases) and non-leukoencephalopathy group (38 cases)according to the cranial MRI T2 scanning.The all patients of 2 groups were evaluated by cholinergic pathways hyperintensities scale (CHIPS) and reforming Scheltens scale.The cognitive function of all patients were evaluated by Montreal cognitive assessment (MoCA).The difference of the cognitive function between 2 groups was observed,and the relationship between CHIPS score,reforming Scheltens scale score and MoCA score was investigated.Results There were statistical differences in MoCA total score and visuospatial/execution,memory,attention score between leukoencephalopathy group and non-leukoencephalopathy group [(20.86 ± 4.52) scores vs.(23.47 ± 4.49) scores,(3.80 ± 1.68) scores vs.(3.11 ± 1.47) scores,(2.78 ±1.57) scores vs.(1.95 ± 1.80) scores,(4.00 ± 2.08) scores vs.(3.87 ± 2.04) scores] (P ＜ 0.01 or ＜ 0.05).There were statistical differences in CHIPS score and reforming Scheltens scale score between cognitive dysfunction group (35 cases)and non-cognitive dysfunction group (24 cases)[(47.77 ± 12.36) scores vs.(39.83 ±7.98) scores,(5.14 ± 1.73) scores vs.(2.58 ±2.10) scores] (P ＜0.01).There was negative correlation between MoCA total score and frontal periventricular score,occipital periventricular score,parietal lobe score,periventricular total score,deep alba total score and reforming Scheltens scale total score (P ＜0.01).There was negative correlation between visuospatial/execution score,attention score,fixing score,MoCA total score and CHIPS score (P ＜ 0.01).There was negative correlation between attention score,fixing score,MoCA total score and reforming Scheltens scale score (P ＜ 0.01).Conclusions In acute cerebral infarction patients leukoencephalopathy is probably related to cognitive function,and the severity of leukoencephalopathy correlates with the degree of cognitive function impairment.Different parts leukoencephalopathy can induce different influence on cognitive function.The cognitive function impairment caused by leukoencephalopathy correlates with the impairment of cholinergic pathways,with main effects of visuospatial/execution function,and the severity correlates with the impairment of cholinergic pathways.
