Objective To observe the changes of lipoprotein‐associated phospholipase A2(Lp‐PLA2) in patients with athero‐thrombosis acute ischemic stroke and the correlation of Lp‐PLA2 with cerebra infarction volume ,neurologic impairment and early prognosis .Methods A total of 104 patients with atherothrombosis acute ischemic stroke and 100 healthy people(controls) were collected .The levels of Lp‐PLA2 were detected by immunoturbidimetry .The cerebral infarction volume was checked by Cranial MRI or CT .The neurological impairment degree was assessed by National Institute of Health Stroke Scale (NIHSS) score .The early prognosis was assessed by Barthel index .The changes of serum Lp‐PLA2 levels in patients with different infarct volumes and neurologic impairment were compared ,the influence of early prognosis were analysised .Results The levels of serum Lp‐PLA2 in the patients with atherothrombosis ischemic stroke were significantly higher than those in control group (P<0 .05) ,and signifi‐cantly correlated with the levels of serum LDLC (r=0 .859 ,P<0 .05) .The levels of serum Lp‐PLA2 were significantly correlated with the increasing of cerebral infarction volume and cerebral neurological impairments (r=0 .531 ,P<0 .05 ;r=0 .623 ,P<0 .05) . The patients with higher level of Lp‐PLA2 has poor prognosis(P<0 .05) .Conclusion The level of Lp‐PLA2 was significantly higher in patients with atherothrombosis ischemic stroke and may reflect the severity and early prognosis in patients with athero‐thrombosis acute ischemic stroke .

Objective The immune hypofunction of the red blood cell on maintenance hemodialysis patients is one main reason of tumor,and oxidative stress is proved to be involved in decrease of existence quality and the occurrence of various complications of patients with hemodialysis.To investigate the status of erythrocyte immune and high oxidative stress of the hemodialysis patients,as well as the effect of Huangqifuzitang on immune function of red blood cell and oxidative stress in patients with hemodialysis.Methods Twenty healthy people were chosen as control group,and 20 patients were selected as the treatment group.CD58,CD59,superoxide dismutase(SOD),malonaldehyde(MDA) were measured before hemodialysis and after 12 days administration of Huangqifuzitang in the treatment group,and compared with those of the control group.Results There was significant difference between before and after taking Huangqifuzitang in treatment group and control group in terms of CD58 ((38.02 ±8.98) vs.(47.39 ±7.78) vs.(59.10±4.59),F=4.506,P=0.000),CD59 ((62.69 ± 20.84) vs.(80.95 ± 20.42) vs.(193.86 ± 19.87) ; F =239.347,P =0.000),SOD ((68.09 ± 11.86) vs.(78.73±10.58) vs.(111.09±16.61) kU/L;F=21.318,P=0.000),MDA((5.98±2.06) vs.(4.54 ±0.62) vs.(3.03 ± 1.10) μmoL/L;F =55.359,P =0.000) levels.Before taking Huangqifuzitang,the concentration of CD58,CD59 and SOD in treatment group was significant decreased compared with control group,but MDA significant increased,and there was significant difference (P ＜ 0.01).After 12 days administration of Huangqifuzitang in the treatment group,the concentration of CD58,CD59 and SOD was significant increased compared with before taking Huangqifuzitang,but MDA significant significant decreased,and there was significant difference (P ＜ 0.01 or P ＜ 0.05) Conclusion The red blood cell surface receptors CD58,CD59 decreased and oxidative stress index SOD decreased significantly,MDA increased significantly in hemodialysis patients.Huangqifuzitang was proved to be with the ability of enhancing the immune of red bloodCD58,CD59 and decreasing the oxidative stress level in patients with hemodialysis.

Severe tracheal stenosis can not only cause critical medical problems such as severe shortness of breath, hypoxia, and even orthopnea, but also impose overwhelming challenges on the physicians, particularly the anesthesiologist. Life-threatening airway obstruction can make the patient's gas exchange extremely difficult.Though several options could be offered regarding the treatment of tracheal stenosis, normally, tracheal resection and following reconstruction is the first choice for severe airway stenosis. Successful surgical intervention relies on the close communication and cooperation between surgeons and anesthesiologists. In these cases, airway management is the top issue for the anesthesiologist, and the level of difficulty varies with stenosis location, severity of stenosis, and surgical technique. Extracorporeal membrane oxygenation (ECMO), or cardiopulmonary bypass (CPB), is rarely utilized for the surgery, but for those impossible airways due to nearly complete tracheal obstruction, ECMO or CPB could be the final choice for anesthesiologists. Here we report a case of successful urgent airway management for tracheal resection and reconstruction assisted by temporary CPB.

Objective To investigate feasibility and early stage postoperative complications of lapa-roscopic radical cystectomy ( LRC) . Methods We retrospectively analyzed the data of 63 consecutive pa-tents (58 males and 5 females) who underwent LRC from Oct .2011 to Oct.2013 in our institute.Of these patients, 46 patients underwent ileal conduit , 9 patients underwent ureterocutaneostomy , and 8 patients un-derwent orthotopic ileal neobladder urinary diversion .The average age and body mass index of patients were 67.7±11.1 (33-84) years and 23.3±2.1 (18.8-28.7) kg/m2, respectively.The mean hemoglobin and al-bumin of patients were (130.7±20.3) g/L and (38.9±4.1) g/L, respectively.Comorbidities of hyperten-sion, diabetes, coronary heart disease and decompensated liver cirrhosis were found in 10, 6, 2 and 1 pa-tient, respectively.10 of 61 patients had a history of abdominal surgery .The indications for cystectomy were classified as muscle invasive bladder cancer for 30 patients, unresectable superficial bladder cancer for 19 patients and recurrent bladder cancer for 14 patients.Postoperative data and early stage postoperative compli-cations within 3 months after surgery were collected . Results The median operative time for LRC and uri-nary diversion was 390 (260-480) min, with a median estimated blood loss of 400 (100-1 500) ml.This was one patient converted to open surgery .The mean postoperative hemoglobin and albumin of patients was 108.5±14.7 g/L and 29.5±3.7 g/L, respectively, both of which significantly reduced compared with pre-operative data (P<0.01).The median duration of hospital stay was 15 days.The median time for liquid in-take, abdominal drainage removal and ureteral stent removal was 4 days, 9 days and 2 months after surgery , respectively.Catheter was removed 2 weeks after laparoscopic orthotopic cystectomy .21 (33.3%) of 63 pa-tients suffered from perioperative complications .15 of 46 patients (32.6%) in ileal conduit group had com-plications including ileus ( 5, 1 of 5 need re-operation ) , lymphatic fistulas ( 5) , pulmonary infection ( 1) , pyelonephritis (1), delirium (1), anastomotic leak (1, re-operation was needed) and pneumothorax (1). 2 of 9 patients (22.2%) in ureterocutaneostomy group had complications such as ileus (1) and lymphatic fistulas (1).4 of 8 patients (50.0%) in orthotopic ileal neobladder group suffered from complications like ileus (2, 1 of 2 required re-operation), lymphatic fistulas (1) and arrhythmia (1). Conclusions LRC is technically feasible and safe .It reduces the estimated blood loss and postoperative complications .It is noteworthy to surgeons that serum albumin significantly reduced after LRC , nutrition should be kept balanced after surgery.

C57BL/6 mice were inoculated intranasally (50 microl) with serial 10-fold dilution of HAB/01 H5N1 virus. Three and five days later, three mice of each group were euthanized. Lung injury was assessed by observation of lung histopathology, virus titers and MCD50 were also measured. Our data showed that H5N1 viral infection in mice resulted in mainly epithelial injury and interstitial pneumonia, featuring significant weight loss, dramatically increased lung wet weight:body weight ratio, inflammatory cellular infiltration, alveolar and interstitial edema, hemorrhage in lungs with high virus titers, and MCD50 was 10(-6.5)/ 0.05 mL. These results suggested that a mouse model of H5N1 viral infection was successfully established which may benefit study of H5N1 avian influenza virus and pathogenic mechanism of host.
